As far as the actuator 200 is concerned, there is a button 10 that can be switched between a first height position and a second height position that is different from the first height position by pressing, and the first height position and the second height position are preferably are designed to be in the same vertical direction. The button 10 is connected with the extruding plate 2 through the support arm 6, and is used to drive the extruding plate 2 to move up and down. The pressing plate 2 is used to drive the deformation of the sealing member 300 so that the sealing member 300 is in sealing contact with the inner wall of the container body 400 .

The support arm 6 has a first fulcrum portion 631 , a second fulcrum portion 632 and a third fulcrum portion 633 . The first fulcrum part 631 is rotatably connected with the button 10, or is rotatably and slidably connected with the button 10, and the second fulcrum part 632 is rotatably connected with the cover body 100, or is rotatably and slidably connected with the cover body 100, The third fulcrum portion 633 is rotatably connected with the extruding plate 2 , or is rotatably and slidably connected with the extruding plate 2 . In order to ensure that the button 10 can normally drive the extrusion plate 2 to move, at least two of the first fulcrum portion 631 , the second fulcrum portion 632 and the third fulcrum portion 633 are rotatably and slidably connected. The two fulcrum parts that are rotatably and slidably connected are preferably designed to slide horizontally in the sliding direction, and the sliding directions of the two fulcrum parts can also be designed to be the same direction.

It can be seen from the above technical solutions that the sealing cover disclosed in the present application is constructed by the actuator 200 , the support arm 6 , the extruding plate 2 and the sealing member 300 . Therein, there is provided a button 10 that can be switched between a first height position and a second height position different from the first height position by pressing.

Wherein, the first fulcrum part 631 is used for connecting the button 10, the second fulcrum part 632 is used for connecting the cover body, and the third fulcrum part 633 is used for connecting the extruded plate 2, and at least two fulcrum parts among the three fulcrum parts can be Turn to slidably connect. Therefore, the movement of the button 10 can drive the support arm 6 to swing up and down, and then drive the third fulcrum part 633 to move up and down to drive the extrusion plate 2 to move up and down. Through the design of the arm 6, the overall structure is simple, the operation is more convenient and labor-saving, and the user experience is improved.

The above is the first embodiment of a sealing cover provided by the embodiment of the present application, and the following is the second embodiment of a sealing cover provided by the embodiment of the present application, please refer to FIG. 1 to FIG. 15 for details.

Based on the scheme of the first embodiment above:

Further, in order to better realize the driving of the pressing plate 2 by the button 10 through the support arm 6 . Any two of the first fulcrum portion 631 , the second fulcrum portion 632 and the third fulcrum portion 633 are rotatably and slidably connected, and the other fulcrum is rotatably connected. That is, the first fulcrum part 631 and the second fulcrum part 632 may be rotatably and slidably connected, while the third fulcrum part 633 may be rotatably connected. Or the first fulcrum part 631 is rotatably connected, and the second fulcrum part 632 and the third fulcrum part 633 are rotatably and slidably connected.

Further, in the present application, the first fulcrum portion 631 , the second fulcrum portion 632 and the third fulcrum portion 633 may be distributed in a non-collinear manner as shown in FIG. 6 on the side projection plane. This non-collinear distribution mode can make the structural arrangement flexible, and is conducive to further simplifying the structure.

Further, in the present application, the fulcrum part that is rotatably connected can be rotatably connected as a whole, that is, the support arm 6 is integrated with the cover body 100, or with the button 10, or with the extrusion plate 2 forming. In the integral molding design, the hinged fulcrum of the support arm 6 is connected with the corresponding parts to be integrally formed in a repeatable bending manner, and then the fulcrum of the support arm 6 can be hinged after integral molding Therefore, the assembly work for the fulcrum portion is reduced. Those skilled in the art can make appropriate transformations based on this, and there is no specific limitation. The specific integral molding situation can be as follows. When the support arm 6 and the button 10 are integrally formed, the second fulcrum portion 632 and the third fulcrum portion 633 are respectively rotatably and slidably connected. When the supporting arm 6 and the cover body 100 are integrally formed, the corresponding first fulcrum portion 631 and the third fulcrum portion 633 are rotatably and slidably connected. When the supporting arm 6 is integrally formed with the extrusion plate 2 , the corresponding first fulcrum portion 631 and the second fulcrum portion 632 are rotatably and slidably connected. It should be noted that the part of the support arm 6 and the cover body 100 can be integrally formed according to the structure of the cover body 100. For example, if the cover body 100 has an upper cover 4 and a lower cover 5 as an example, then the support arm 6 can be It is integrally formed with the upper cover 4 or the lower cover 5 , and its integral forming can refer to the aforementioned integral forming design between the button 10 and the straight arm 6 , and will not be described in detail.

Further, the distance between the rotation axis of the first fulcrum part 631 and the rotation axis of the second fulcrum part 632 is greater than the distance between the rotation axis of the second fulcrum part 632 and the rotation axis of the third fulcrum part 633 . It should be noted that, in this embodiment, the rotation axis refers to an axis around which the fulcrum part can rotate relatively. Through such a design, the strokes of the button 10 and the pressing plate can be different, so that the pressing of the button 10 can save effort, and at the same time, the thickness of the cover can be reduced while maintaining a better operating experience.

Further, in terms of the structure of the support arm 6 , as shown in FIG. 9 , it includes a power arm 61 and a resistance arm 62 .

The first end of the resistance arm 62 is vertically connected to the power arm 61, and the distance between the resistance arm 62 and the power arm 61 is T-shaped distribution as shown in FIG. A third fulcrum portion 633 is provided. In this embodiment, in order to better adapt to the connection with the button 10, the first end of the power arm 61 can be provided with an inwardly concave avoidance groove 611, which can form a kind of clamping for the button 10 and improve The stability of the connection. Taking the first fulcrum part 631 rotatably set, the second fulcrum part 632 and the third fulcrum part 633 rotatably and slidably set as an example, the principle of the button 10 driving the extrusion plate 2 through the support arm 6 is as follows:

When the button 10 moves down, the power arm 61 is driven to swing downwards. When the power arm 61 swings downwards, it also drives the resistance arm 62 to move down. Since the first fulcrum portion 631 is rotatably arranged, the power arm 61 moves downward. The swing and the subsequent downward movement of the resistance arm 62 will generate a horizontal displacement component, and the horizontal displacement component produced by the power arm 61 can be released by the second fulcrum part 632 which is rotatably and slidably arranged on the power arm 61, so that the power arm 61 can swing down smoothly. The horizontal displacement component generated by the resistance arm 62 can be released by the rotatable and slidable third fulcrum portion 633 on the resistance arm 62 , so that the resistance arm 62 can move down smoothly to push the extrusion plate 2 .

Further, as shown in FIG. 9 , in terms of the structure of the fulcrum, the first fulcrum 631 , the second fulcrum 632 and the third fulcrum 633 can all be shafts, then the button 10 , the cover 100 and the extrusion The plate 2 can also be correspondingly provided with a hole or groove structure matched with the shaft.

Wherein, the upper cover 4 is installed on the top of the lower cover 5 , and the bottom surface of the upper cover 4 and the top surface of the lower cover 5 are spaced apart to form a gap cavity 101 for the extrusion plate 2 to move. The upper cover 4 is also provided with an escape hole 41 for the escape button 10 .

The positioning part 15 is arranged in the middle of the inner bottom surface of the cover body 100, and the whole is also in a cylindrical structure. The bottom surface of each convex strip 151 is provided with a slope that cooperates with the second rotating tooth 132 of the rotating part 13, so that it can be pushed during the actuation process. The rotating member 13 rotates. When the rotating member 13 is rotated due to actuation, and when the channel 131 of the rotating member 13 is no longer aligned with the protrusion 151 of the positioning member 15, the protrusion 151 will abut against the second rotating tooth 132 of the rotating member 13, thereby The rotating member 13 is positioned at a lower position, that is, the extrusion plate 2 is restricted at a lower position at this time, thereby maintaining the extrusion of the extrusion plate 2 to the sealing member 300 .

As far as the structure of the button 10 is concerned, it may be composed of a gland 11 and a rotating auxiliary part 12. It should be noted that the gland 11 and the rotating auxiliary part 12 may be detachable or integrally formed. The gland 11 moves upwards to protrude from the avoidance hole 41 of the cover body 100 . Its design purpose is to facilitate the user's pressing operation, and at the same time, it can be matched with the cover body 100 to improve the overall aesthetics. Of course, it is also possible not to set the pressing cover 11, that is, the button 10 is directly the rotation auxiliary part. In this embodiment, the first fulcrum portion of the support arm 6 is specifically connected to the rotation assisting member 12 .

Taking the configuration of the gland 11 as an example, the rotation auxiliary part 12 is connected to the bottom of the gland 11 and has a cylindrical structure as a whole. Specifically, the rotation auxiliary part 12 is provided with a rotating shaft 14 for installing the rotating part 13, and the rotating part 13 is buckled. 133 is clamped on the rotating shaft 14 of the rotating auxiliary member 12 .

In this application, as shown in Fig. 3, Fig. 4 and Fig. 9, Fig. 10, as far as the design of the gap cavity 101 is concerned, the gap cavity 101 can be designed to penetrate horizontally or the side of the cover body 100 can have a visible The visible area of the gap cavity 101 is communicated so that the extruded plate 2 can be observed through the design or the visible area. The extruding plate 2 is provided with a prompting part that can leak out after the driving sealing member 300 is deformed, so that when the user observes the prompting part, it can be considered that the sealing cover has been sealed. In addition, when the sealing member 300 is installed, it can form a shield to the visible area before deformation, thereby reducing the exposure of the internal structure of the cover and improving the aesthetics; The situation of the prompt part is observed in the visible area, so as to avoid the situation that affects the judgment of the user. That is, when the user cannot observe the prompting part of the pressing part, it can be judged that the sealing cover is in the open state. After the sealing member 300 is deformed, it can form an observation gap 102 connected with the gap cavity 101 in the vertical direction between it and the cover body 100 , so that the user can observe the prompt part through the observation gap 102 . That is, when the user can observe the prompt part through the observation gap 102, it can be judged that the sealing cover is in a sealed state.

Take the extruded plate 2 with an observable design and the upper cover 4 with an extended flange 44 as an example:

The working process of the sealing cover from the open state to the sealed state:

Put the lid on the opening of the container body 400, press down the gland 11, the rotating auxiliary part 12 and the rotating part 13 will move downward accordingly, push the support arm 6 to swing downward, and the third fulcrum part 633 of the support arm 6 will go down accordingly. Move and push the extrusion plate 2 to move down. The extrusion plate 2 moves down and squeezes the sealing member 300 on the lower cover 5, so that the sealing member 300 is deformed, and the second sealing ring part 72 of the sealing member 300 is squeezed on the inner wall of the container body 400, so that the mouth of the tank is in a sealed state . At this moment, since the second sealing ring part 72 deforms and moves down, a certain height difference will be formed between the second sealing ring part 72 and the extending flange 44 , thereby forming an observation gap 102 . At the same time, the extrusion plate 2 is exposed from the observation gap 102 between the upper cover 4 and the sealing member 300 , and the user can see the extrusion plate 2 from the side of the container body 400 . When the movement value of the upper surface of the gland 11 is slightly lower than the upper surface of the upper cover 4, the gland 11 moves to the lowest point, and the rotating member 13 triggers the rotation, and the gland 11 is released at this time. The elastic force of the spring 3 makes the gland 11 rebound slightly, and the groove 131 of the rotating member 13 is no longer aligned with the raised line 151 of the positioning member 15 due to the rotation of the rotating member 13, and the raised line 151 and the second rotating tooth 132 of the rotating member 13 are offset , the height position of the rotary member 13 is locked, so that the position of the gland 11 is locked. At this time, the upper surface of the gland 11 and the upper surface of the upper cover 4 are at the same height, the sealing member 300 is still pressed on the inner wall of the container body 400, the extrusion plate 2 can still be observed from the side of the container body 400, and the sealing cover is completely opened from the open state. Switch to sealed state.

The working process of the sealing cover from the sealed state to the open state:

Press down the gland 11 again, and the rotating member 13 will trigger the rotation. At this time, the gland 11 will be released, and the channel 131 of the rotating member 13 will be aligned with the protrusion 151 of the positioning member 15. The rotating member 13 will be unlocked, and the elastic force of the spring 3 will make the rotating member 13, rotate The auxiliary part 12 and the gland 11 continue to reset upward to the initial position, and at the same time drive the support arm 6 to swing upward, and the third fulcrum portion 633 of the support arm 6 moves upward accordingly and drives the extrusion plate 2 to move upward. The extrusion plate 2 no longer squeezes the sealing member 300, the sealing member 300 returns to its original shape under its own elasticity, and no longer clings to the inner wall of the container body 400, the sealing member 300 and the extended flange 44 of the upper cover 4 contact again, or The sealing member 300 does not cover the bottom of the extended flange 44 upwards, thereby covering the extrusion plate 2 so that it cannot be observed from the side of the container body 400, and the sealing cover completes the switch from the sealed state to the open state.
