Description

Technical field

The invention relates to the field of bathroom appliances, in particular to an open-close type shower door with an automatically closing door closing system, which is mounted in a shower room.

Background technology

At present, when people decorate, a shower room is usually arranged in a toilet, and the shower room usually uses a shower door with a glass sheet. The shower door comprises an open-close type shower door, and is generally provided with a side frame against a wall. The side frame can be made of metal, and the side frame is connected with a fixed glass sheet to realize fixed installation of the fixed glass sheet. A vertical frame is connected to the other side of the fixed glass sheet, or another vertical frame is set against the wall. One side of the movable glass sheet is provided with a vertical rotational shaft, and the rotational shaft is generally made of metal. In order to realize the rotation of the movable door, a metal rotational shaft on the movable door is usually leaned against one side of the fixed glass sheet with the vertical frame. A fixed rotational shaft seat is arranged at an upper end and a lower end of the vertical frame. The rotational shaft seat is matched with the metal rotational shaft. The fixed door and the movable door are connected into a whole, and the movable door can rotate around the rotational shaft, so that the movable door can be opened and closed. Typically the fixed glass sheet is referred to as a fixed door and the shower door comprises at least one movable glass sheet rotatable about the fixed glass sheet. Typically the movable glass sheet is referred to as a movable door.
An existing shower door is usually provided with an automatically closing door closing system. A common closer is provided, one end of the closer is connected with the movable door, and the other end of the closer is connected with a fixed position in the shower room, so that the movable door can be automatically closed. One end of the closer is fixedly connected with the movable door through a clamping piece, and the other end of the closer is rotatably connected with a fixed position. However, in this way, generally, the clamping piece connected with the movable door at one end of the closer is close to the rotational shaft of the movable door, and the rotating central shaft of the rotatable part at the other end is far away from the rotational shaft of the movable door, so that the movable door needs more closing force when closing the door, and a buffer with a larger size is needed to realize the function of the movable door.
In addition, when the existing closer is used on shower doors with different shapes, different fixed pieces need to be matched, and universality is poor in different installation occasions. The existing clamping piece is usually fixed through a lock screw abutting against the glass sheet, but when the shower door is opened and closed, the lock screw is easy to slip on the glass sheet, so that the automatic closing system fails. The existing clamping piece and the main body of the closer are connected by matching the lock nut with the countersunk head screw, and when the shower door is mounted in a left-right interchange mode, the part needs to be disassembled, so that the connection of the part is easy to be loose in use.

As shown in FIGs. 10 through 11, the fitting of the fixed seat 206, the clamping seat 102 and the closer 400 of the present embodiment is suitable for mounting in different scenes. Before installation, the second cavity 219 of the extension piece 208 is preassembled and connected with a tail end of the sliding body 402 of the closer 400, and the connecting block 103 is preassembled and connected with the third cavity 404 of the second end of the main body 401 of the closer 400. Disassembly is not needed when the shower door is mounted, and connection failure caused by repeated disassembly is avoided. When the movable door 100 is used in the manner shown in Fig. 1, from the perspective of Fig. 1, the movable door 100 is positioned on the right side of the side frame 300, and the fixed seat 206 is positioned on the left side of the closer 400, and the clamping seat 102 is positioned on the right side of the closer 400 to be mounted, that is, the fixed seat 206, the clamping seat 102 and the closer 400 need to be connected in a first manner as shown in Fig. 10. The extension piece 208, the connecting block 103, and the closer 400 will now be pre-assembled and connected, to place the extension piece 208 on the left side of the closer 400 and the connecting block 103 on the right side of the closer 400, fixing the projecting strip 216 of the extension piece 208 extending into the right side of the through hole 213, mounting and fixing the clamping table 111 of the clamping plate 104 towards the fourth cavity 109 of the connecting block 103, mounting the fixed plate 210 on the pull rod 203, and mounting the clamping plate 104, the cover plate 105 or the like on the top end of the movable door 100. When the movable door 100 is used in another way, from the perspective of Fig. 1, when the movable door 100 is positioned on the left side of the side frame 300, the fixed seat 206 needs to be positioned on the right side of the closer 400, and the clamping seat 102 is positioned on the left side of the closer 400, that is, the fixed seat 206, the clamping seat 102 and the closer 400 need to be connected in a second way as shown in Fig. 11. At this time, the extension piece 208, the connecting block 103 and the closer 400 will now be pre-assembled and connected, to place the extension piece 208 on the right side of the closer 400, the connecting block 103 on the left side of the closer 400, fixing the projecting strip 216 of the extension piece 208 extending into the left side of the through hole 213, mounting and fixing the clamping table 111 of the clamping plate 104 towards the fourth cavity 109 of the connecting block 103, and mounting the fixed plate 210 on the pull rod 203 to fix the clamping plate 104, the cover plate 105 or the like to the top end of the movable door 100. That is, the projecting strip 216 of the extension piece 208 and the through hole 213 of the fixed piece 207 can be exchanged and assembled leftwards and rightwards, and the fourth cavity 109 of the connecting block 103 and the clamping table 111 of the clamping plate 104 can be exchanged and assembled upwards and downwards, so that the closer 400 can be mounted in shower doors in different directions, without disassembling the connecting part of the extension piece 208 to the sliding body 402 of the closer 400 and the lock nut and stud at the connecting part of the connecting block 103 to the main body 401 of the closer 400.

Of course, the above-described embodiments are only preferred embodiments of the present invention, and when actually applied to a shower room, the same components as those of the above embodiments can be used without changing any parts, or with only changing individual parts, to achieve the object of the present invention.

Industrial applicability

As can be seen from the movement process of the switch-type shower door, the structure of the shower door is more reasonable in mechanics, the same function can be realized by the buffer with smaller size and force, and the structure is simpler, so that the manufacturing cost and difficulty can be saved. Meanwhile, the appearance is more attractive.
The components used by the shower door are advantageous in universality on different shower doors, wider in application range and small in assembly difficulty. The connecting structure of the two ends of the closer is not influenced by replacement. The failure of the connection part of the two ends of the closer due to frequent disassembly and assembly is avoided. The replacement is easy, the shower door can be assembled and replaced on site in a shower room, and the use requirements of different occasions can be met.
