Description

Technical field

The present invention relates to the field of electricity, in particular to a two-motor electric cabinet with pull-out drawers.

State of the art

Electrical cabinets with pull-out drawers are currently known. One of the devices is described in Chinese Patent Application WO2013060127 CN.

Manual work is required to remove existing electrical cabinet removable drawer units. This is an inconvenience when using. Because the pull-out operation is performed using energy, the pull-out drawer cannot be pulled out manually and smoothly. This causes inconvenience in the maintenance of electrical cabinets. A more sophisticated mechanical and electronic design is required for convenient maintenance to achieve pull-out of the pull-out drawer (pushing and manual disassembly). This will have an adverse effect on maintenance and equipment cost.

The essence of the invention

It is an object of the present invention to provide an electric motor cabinet with pull-out drawers that can overcome the aforementioned defects.

According to the present invention, a two-motor electric cabinet with pull-out drawers has a frame and a pull-out drawer. The intermediate wheels are mounted on both sides of the bottom of the pull-out drawer. The spacer wheels are used to align with the transverse guide bar at the bottom of the storage cavity, which is used to place the retractable drawer so that the retractable drawer can be pushed in and out of the storage cavity. The transverse rack is fixedly mounted in the frame at the bottom of the transverse guide bar. The transverse rack holds the drive sliding block member. The drive sliding block member has two support plates mounted on the left and right sides, a U-shaped frame consisting of bottom walls fixedly connected between the two support plates and a sliding block which slides between the two U-shaped frame support plates. The holes in the slab, which are aligned with each other, are located on both support plates. The freestanding unit has two flexible plate guides mounted in the front and rear and a contour bottom which is located between two flexible plates (wires and rigidly connects them. Two flexible plates (wires used to press into the notch on the underside of the drawer drawer, to move the retractable drawer to the left and to the right The contour bottom includes the left vertical plane, the slope portion, the horizontal plane part, and the right vertical plane left to right The lower side of the contour bottom is connected to the upper side of the lower wall through the pressure spring. the vertical part and the right part of the vertical plane are connected respectively to one of the two support plates. The horizontal part is connected to the lower edge of the transverse batten by a pressure spring. passes through the holes in the plate and passes through two flexible plates (wires. The bolt hole is mounted in the bottom wall by aligning it with a threaded rod screwed to the first motor so that the freely sliding block moves to the left and to the right. The other end of the threaded rod is connected to the second motor. The second motor is used to rotate the threaded rod. The downward pressure rod which extends to the right side is rigidly mounted on the left side of the frame. The downward pressure slope is mounted at the end of the pressure bar to connect a portion of the slope so that the freely sliding unit overcomes the pressure spring and is pressed down. This way, two flexible panels (wires would leave a groove.

Because of the use of a stationary downwardly pressed bar, it can be mounted with a freely sliding block and continue to be pushed to achieve disengagement, provided the drawer is pulled in place. In addition, the drawer can easily be pulled out of the entire drawer unit frame for further maintenance. Since there are two motors where the first motor cannot operate normally, the second motor can start rotating the threaded rod so as to push the U-shaped frame and ensure that the electric pull-out drawer can be used in a stable manner. The whole unit does not require additional electronic sensors and other complicated equipment. In addition, the unit can ensure simple and reliable operation. Each element of the whole unit is tensioned in a stable and balanced manner. Thus, the unit can meet the energy stability and reliability requirements.

Detailed implementation

The present invention is described in detail with reference to Figure 1-2.

Referring to Figure 1-2, a two-motor electric cabinet with pull-out drawers has a frame (9) and a pull-out drawer (8). The intermediate wheels (81) are mounted on both sides of the lower part of the pull-out drawer (8). The spacer wheels (81) are used to align with the transverse guide bar (92) at the bottom of the insertion cavity (91), which is used to accommodate the retractable drawer (8) so that the retractable drawer (8) can be pushed in and out of the insertion cavity (91). The cross-member (41) is fixedly mounted in the frame (9) at the bottom of the transverse guide rail (92). The transverse shelf (41) holds the drive sliding block member (7). The drive sliding block element (7) has two support plates (731, 732) mounted on the left and right sides, a U-shaped frame (73) consisting of bottom walls (735) fixedly connected between the two support plates and freely sliding. a block (72) which slides between two support plates of the U-shaped frame (73). The panel holes (734), which align with each other, are arranged on both support plates (731, 732). The freely sliding block (72) has two flexible plate tongues (721) which are mounted in the front and rear directions and a contour bottom (71) which is interposed between the two flexible plate tongues (721). Two slabs of the flexible plate (721) are used to press into the recess (82) on the underside of the lower wall of the pull-out drawer (8) so as to move the pull-out drawer (8) to the left and right. The contour bottom (71) includes a left vertical plane portion (713), a slope portion (711), a horizontal plane portion (712), and a right vertical plane portion (714) from left to right. The lower half of the contour bottom (71) is connected to the upper half of the lower wall (735) via a pressure spring (75). The left vertical plane (713) and the right vertical plane (714) are connected to one of the two support plates (731, 732) respectively. The portion (712) of the horizontal plane is connected to the lower edge of the transverse strip (41) by applying a pressure spring (75). The transverse strip (41) passes through the holes (734) of the panel and passes through the recesses (721) of the two flexible panels. The bolt hole is provided in the bottom wall (735) by aligning it with a threaded rod (51) screwed to the first motor (5) so that the freely sliding block (72) moves left and right. The other end of the threaded rod (51) is connected to the second motor (55). The second motor (55) is used to rotate the threaded rod (51). The downward pressure rod (6) extending to the right is rigidly mounted on the left side of the frame (9). The downward pressure slope (61) is mounted at the end of the pressure bar (6) to engage the slope portion (711) such that the freely sliding block (72) overcomes the pressure spring (75) and is pressed down. In this way, the two flexible panel rims (721) would leave a groove (82).

According to an embodiment, the upper side of the transverse strip 41 is slidably mounted with the upper side wall of the panel hole 734 holding the U-shaped frame 73.

The first motor 5 moves the U-shaped frame 73. Then, in action, the two flexible slabs of the plate and the notch 82 are pushed out of the pull-out drawer 8 to move left and right. When the pull-out drawer 8 is pushed outward, i.e. to the left, the end of the downwardly pressing rod 6 does not contact the slope portion of the contour bottom 71, provided that drawer 8 is not required. When drawer 8 is to be withdrawn, the first motor continues to push the U-shaped frame 73 to move to the left. The downwardly pressing rod then contacts the slope portion so that the freely sliding block is pressed downward. In this way, the two slabs of the flexible plate are pressed down to leave a notch 82. At this point, the retractable drawer 8 can be manually pulled out of the frame.

The second engine 55 is a standby engine. When the first motor 5 is not able to operate normally, the second motor 55 can start to rotate the threaded rod 51. Thus, the U-shaped frame 73 is pushed to move and provide stable operation of the electric pull-out drawer.

Based on the above, various modifications can be made by those skilled in the art according to the mode of operation as defined within the scope of the present invention.
