Abstract
Description
Technical Field
[0001] This utility model relates to the field of low-pressure cabinet technology, and in particular to a low-pressure cabinet drawer and its anti-fall device. Background Technology
[0002] Please see Figure 1 , Figure 1 This is a structural schematic diagram of an embodiment of a prior art low-pressure drawer cabinet. Figure 1 When using the low-pressure cabinet drawers, staff need to hold the front panel of the drawer with both hands and press the unlock button to pull it out. Because there is no limit stop, it is easy to pull the drawer directly out of the cabinet. Furthermore, due to the weight of the drawer, it is easy to fall directly to the ground, which can easily damage the important primary and secondary moving parts behind the drawer, causing losses.
[0003] Additionally, please see Figure 2 For safety reasons, when performing simple repairs or inspections, staff often pull the drawers directly out of the cabinet to perform the work, which is time-consuming and laborious. Utility Model Content
[0004] This invention aims to at least partially solve one of the technical problems in the related art. Therefore, one objective of this invention is to provide a low-pressure cabinet drawer that prevents the drawer from falling out when it is pulled out of a cabinet.
[0005] The technical solution adopted in this utility model is:
[0006] In a first aspect, this utility model provides an anti-fall device for a low-pressure cabinet drawer, comprising: two anti-fall brackets, which are respectively fixedly installed on the left and right outer sides of the drawer; one end of each anti-fall bracket is provided with a protrusion that can swing up and down, which normally tilts upwards; and an L-shaped crossbeam, one side of which is fixed to the upper edge of the drawer opening of the drawer box, and the other side of which is bent vertically at the first side, forming an L-shape; wherein, when the drawer is pulled out of the drawer box to the end position, the protrusion hooks onto the other side of the L-shaped crossbeam from the left and right sides respectively, thereby limiting the drawer to the drawer box; when the drawer is closed, the protrusion is automatically pressed downwards and separated from the other side, thereby allowing the drawer to be closed.
[0007] When the drawer needs to be fully pulled out, manually push the other end of the anti-fall bracket upwards to make the protrusion swing downwards, separating the protrusion from the other side, thereby allowing the drawer to be fully pulled out.
[0008] The anti-fall bracket is long and narrow, with a through hole in the middle. A first screw is located in the middle of the drawer, and the first screw passes through the through hole to fix the anti-fall bracket to the drawer, so that the anti-fall bracket can swing up and down on the first screw.
[0009] The anti-fall bracket is horizontally mounted on the drawer. One end of the anti-fall bracket has a protrusion, and the other end has a vertical slot. The protrusion is located at the end of the drawer, and the slot is located at the front end. A second screw is located at the front end and passes through the slot. When the other end is moved up and down, the slot moves up and down along the second screw. When the other end is moved down so that the top of the slot is suspended at the position of the second screw, one end of the anti-fall bracket tilts upward, and the protrusion tilts upward. When the other end is moved upward, the protrusion swings downward and moves away from the L-shaped crossbeam.
[0010] The other end of the fall arrestor is a rectangular block with an elliptical opening groove.
[0011] When the opening slot is suspended on the second screw, the center position of the rectangular block is lower than the height of the first screw.
[0012] The protrusion is approximately triangular, with its first side being the hypotenuse and its second side being the vertical side.
[0013] Both the first screw and the second screw are M6 non-standard screws.
[0014] The fall arrestor is also equipped with a reinforcing member, which is located between the through hole and the opening groove to increase the strength of the fall arrestor.
[0015] Secondly, this utility model provides a low-pressure cabinet drawer, including the anti-fall device as described above.
[0016] The beneficial effects of this utility model are:
[0017] This invention overcomes the technical problem in the prior art where drawers are prone to falling off when pulled out by adding anti-fall brackets on the left and right sides of the drawer, with the protrusions of the anti-fall brackets hooking onto the crossbeams on the drawer box.
[0018] Additionally, when the drawer is closed, the protrusion is automatically pressed downwards and separated from the crossbeam, thus allowing the drawer to close.
[0019] In addition, the protrusion can be manually pressed down to separate it from the crossbeam, allowing the drawer to be fully pulled out. Attached Figure Description

[0023] Figure 4 yes Figure 3 A schematic diagram of an embodiment of the anti-fall bracket 1. Detailed Implementation
[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Example 1
[0025] Please refer to the following: Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of one embodiment of the anti-fall device for the low-pressure cabinet drawer of this utility model. Figure 3 As shown, the anti-fall device includes an anti-fall bracket 1 and an L-shaped crossbeam 2.
[0026] There are two anti-fall brackets 1, which are fixedly installed on the left and right outer sides of the drawer respectively. Each anti-fall bracket 1 has a protrusion 11 that can swing up and down. The protrusion 11 is normally tilted upwards. One side of the L-shaped beam 2 is fixed to the upper edge of the drawer opening of the drawer box, and the other side of the L-shaped beam 2 is bent vertically at the first side, forming an L-shape with the other side.
[0027] Specifically, please refer to Figure 4 ,like Figure 4 As shown, the anti-fall bracket 1 is long and narrow. A through hole 12 is provided in the middle of the anti-fall bracket 1. A first screw 3 is provided in the middle of the drawer. The first screw 3 passes through the through hole 12 to fix the anti-fall bracket 1 to the drawer, so that the anti-fall bracket 1 can swing up and down on the first screw 3.
[0028] Furthermore, the anti-fall bracket 1 is horizontally disposed on the drawer. One end of the anti-fall bracket 1 is provided with the protrusion 11, and the other end of the anti-fall bracket 1 is provided with a vertical slot 13. The protrusion 11 is disposed at the end of the drawer, and the slot 13 is disposed at the front end of the drawer. A second screw 4 is disposed at the front end, and the second screw 4 passes through the slot 13. When the other end is moved up and down, the slot 13 can move up and down along the second screw 4.
[0029] When the other end is moved downward so that the top of the opening slot 13 is suspended at the position of the second screw 4, one end of the anti-fall bracket 1 tilts upward and the protrusion 11 tilts upward; when the other end is moved upward, the protrusion 11 swings downward. When the protrusion moves downward to a certain position (for example, when the bottom of the opening slot 13 abuts against the second screw 4), the protrusion 11 leaves the L-shaped crossbeam 2, thereby allowing the drawer to be fully pulled out.
[0030] The other end of the fall arrestor 1 is a rectangular block (not shown in the figure), on which an elliptical opening slot 13 is provided. It should be noted that when the opening slot 13 is suspended from the second screw 4, the center of the rectangular block is lower than the height of the first screw 4. This ensures that when the opening slot 13 is suspended from the second screw 4, the protrusion 11 can move upwards to hook onto the L-shaped crossbeam 2.
[0031] like Figure 4 As shown, the protrusion 11 is approximately triangular, with the first side of the protrusion 11 being the hypotenuse and the second side being the vertical side.
[0032] Both the first screw 3 and the second screw 4 are M6 non-standard screws.
[0033] The fall arrestor bracket 1 is also provided with a reinforcing member 14, which is disposed between the through hole 12 and the opening groove 13 to increase the strength of the fall arrestor bracket 1.
[0034] The working method of this utility model is as follows:
[0035] Pulling out the drawer: Normally, the opening slot 13 is suspended on the second screw 4, and the protrusion 11 is raised upward. When the drawer is pulled out of the drawer box to the end position, it hooks the other side of the L-shaped crossbeam from the left and right sides respectively, thereby limiting the drawer to the drawer box.
[0036] Closing the drawer: As the drawer is pushed into the drawer box, the protrusion 11 is automatically pressed down, and the protrusion separates from the other side of the L-shaped crossbeam, thereby closing the drawer;
[0037] To fully open the drawer: Manually push the other end (i.e., the rectangular block) of the anti-fall bracket 11 upwards. The opening slot 13 disengages from the second screw 4 and moves upwards, causing the protrusion 11 to swing downwards. The protrusion 11 separates from the other side of the L-shaped beam, thereby allowing the drawer to be fully pulled out.
[0038] This utility model has a simple structure, is easy to install, has high versatility, can effectively solve the danger of drawers falling off, and is applicable to all low-pressure drawer cabinets. Example 2
