Detailed implementation manners

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the following further describes the present utility model in detail with reference to the attached Figures 1-11 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] Refer to Figures 1-4, A drawer with a fall prevention function, comprising an upper partition 1, a lower partition 2, a drawer unit 3, a fall prevention hook 4 and a tension spring 5. The upper partition 1 and the lower partition 2 are both fixedly arranged and kept parallel to each other. The drawer unit 3 is slidably arranged between the upper partition 1 and the lower partition 2. One side of the drawer unit 3 is set as a side plate 31. In order to prevent the drawer unit 3 from completely sliding out and falling between the upper partition 1 and the lower partition 2 during the process of pulling the drawer unit 3, the fall prevention hook 4 is set to include a hook body part 41 and a connecting rod part 42. The connecting rod part 42 of the fall prevention hook 4 is hinged to the side plate 31 of the drawer unit 3, and the two ends of the tension spring 5 are respectively fixed to the connecting rod part 42 and the side plate 31, and the tension spring 5 and the hook body part 41 are located at both ends of the connecting rod part 42.

[0032] Correspondingly, a baffle 6 is vertically arranged at one end of the upper partition 1, so that the baffle 6 protrudes from the bottom end of the upper partition 1. Under the action of the tension spring 5, the hook body part 41 of the fall prevention hook 4 is turned upwards, so that the horizontal position height of the top end of the hook body part 41 is higher than the horizontal position height of the bottom end of the baffle 6. When the drawer unit 3 is pulled outwards between the upper partition 1 and the lower partition 2, the hook body part 41 of the fall prevention hook 4 abuts against the baffle 6 under the action of the tension spring 5, and the baffle 6 plays a role in limiting the outward sliding of the drawer unit 3.

[0033] Refer to Figure 4 , Figure 5 and Figure 6 , when it is necessary to clean the inside of the drawer unit 3, in order to facilitate the removal of the drawer unit 3 between the upper partition 1 and the lower partition 2 to clean the inside of the drawer unit 3, a lifting part 43 is also arranged in the fall prevention hook 4, so that the lifting part 43 and the hook body part 41 are respectively located at both ends of the connecting rod part 42. When it is necessary to clean the inside of the drawer unit 3, lift the lifting part 43 to make the fall prevention hook hinged to the side plate 31 rotate, so that the horizontal position height of the top end of the hook body part 41 is lower than the horizontal position height of the bottom end of the baffle 6. Thus, when the drawer unit 3 is completely pulled out between the upper partition 1 and the lower partition 2, the baffle 6 will not produce a blocking limit on the hook body part 41. At the same time, a lifting groove 311 is formed at the top end surface of the side plate 31, and the position of the opened lifting groove 311 corresponds to the position of the lifting part 43. Lift the fall prevention hook 4 from the lifting groove 311. The opening of the lifting groove 311 facilitates the lifting of the fall prevention hook 4, so that the drawer unit 3 is pulled out and removed between the upper partition 1 and the lower partition 2.

[0034] In order to achieve the hinge connection between the connecting rod portion 42 of the anti-falling hook 4 and the side plate 31, a hinge post 312 is fixedly provided on the side plate 31. Correspondingly, a hinge hole 421 is formed in the connecting rod portion 42. The hinge post 312 on the side plate 31 passes through the hinge hole 421 of the connecting rod portion 42, thereby enabling the anti-falling hook to be hinged to the side plate 31. In order to fix the two ends of the tension spring 5 to the connecting rod portion 42 and the side plate 31 respectively, a first fixing post 422 is provided on the connecting rod portion 42, and a second fixing post 313 is provided on the side plate 31, thereby fixing the two ends of the tension spring 5 to the first fixing post 422 and the second fixing post 313 respectively.

[0035] The distance dimension between the hinge post 312 and the hook body portion 41 is set to "A", the distance dimension between the first fixing post 422 and the hinge post 312 is set to "L", and the distance dimension between the first fixing post 422 and the lifting portion 43 is set to "D", and A = L = D is satisfied. This makes the fixing position of the tension spring 5 on the connecting rod portion 42 maintain an appropriate distance from the hinge position of the connecting rod portion 42, avoiding the situation where the distance is too small and making it difficult for the tension spring 5 to pull the hook body portion 41 in the reverse direction, resulting in a poor abutting effect between the hook body portion 41 and the baffle 6; at the same time, it also avoids the situation where the distance is too large, and the hinge position of the tension spring 5 on the connecting rod portion 42 is too close to the lifting portion 43, making it inconvenient to release the abutting between the hook body portion 41 and the baffle 6 by lifting the lifting portion 43. At the same time, the position of the hook body portion 41 on the side plate 31 is controlled, thereby controlling the maximum extraction degree of the drawer unit 3.

[0036] The lifting portion 43 is set to be waist-shaped. In order to limit the flipping angle of the anti-falling hook 4, a sliding groove 431 is formed along the length direction of the lifting portion 43. Correspondingly, a guiding post 314 is fixedly provided on the side plate 31, and the guiding post 314 on the side plate 31 is engaged in the sliding groove 431 of the lifting portion 43. When the guiding post 314 abuts against the bottom end of the sliding groove 431, the abutting between the hook body portion 41 and the baffle 6 is released, and the drawer unit 3 can be pulled out from between the upper partition 1 and the lower partition 2. By engaging the guiding post 314 in the sliding groove 431 of the lifting portion 43, the flipping of the anti-falling hook 4 is guided.

[0037] Refer to Figure 7 and Figure 8, In addition, in order to further restrict the flipping of the anti-falling hook 4 and further facilitate the lifting of the lifting part 43, a horizontal plate 32 is horizontally and fixedly arranged at the top end of the side plate 31, so that the horizontal plate 32 protrudes from the surface of the side plate 31, and a first through groove 321 and a second through groove 322 are formed by opening in the horizontal plate 32. The position of the opened first through groove 321 corresponds to the position of the hook body part 41, so that the hook body part 41 passes through the first through groove 321, and the position of the opened second through groove 322 corresponds to the position of the lifting part 43, so that the lifting part 43 passes through the second through groove 322. The opening of the second through groove 322 further facilitates the lifting of the lifting part 43. In addition, the setting of the horizontal plate 32 plays a limiting role in the flipping of the anti-falling hook 4.

[0038] Referring to Figure 9 , Figure 10 and Figure 11 , the specific implementation principle of the embodiment of the present application is as follows: The anti-falling hook 4 on one side of the drawer unit 3 flips under the action of the tension spring 5, so that the horizontal position height of the top end of the hook body part 41 is higher than the horizontal position height of the bottom end of the baffle 6. When the drawer unit 3 is pulled out of the cabinet body, the hook body part 41 of the anti-falling hook 4 abuts against the baffle 6; thereby playing a limiting role in the pulling out of the drawer unit 3, preventing the drawer unit 3 from being separated from the cabinet body, and causing the phenomenon that the drawer unit 3 falls.

[0039] When it is necessary to clean the inside of the drawer unit 3 and take out the drawer unit 3 from the cabinet body, the lifting part 43 is lifted from the lifting groove 311 of the side plate 31 and the second through groove 322 of the horizontal plate 32, so that the anti-falling hook 4 flips, resulting in the descent of the hook body part 41 until the horizontal position height of the top end of the hook body part 41 is lower than the horizontal position height of the bottom end of the baffle 6. When the drawer unit 3 is pulled out of the cabinet body, the abutment between the hook body part 41 of the anti-falling hook 4 and the baffle 6 is released, and thus the drawer unit 3 can be directly pulled out of the cabinet body. Therefore, not only does it have a good anti-falling effect on the drawer unit 3, effectively protecting the drawer unit 3 and personal safety; at the same time, it is convenient to release the anti-falling function of the anti-falling device of the drawer unit 3.

[0040] The present utility model also discloses a power distribution cabinet, including a cabinet body and a drawer, and the drawer is the drawer with an anti-falling function of the present utility model. A plurality of drawer slots are arranged in the cabinet body, an upper partition plate 1 and a lower partition plate 2 are fixed in the drawer slots, the upper partition plate 1 is fixed on the upper surface of the drawer slot, and the lower partition plate 2 is fixed on the lower surface of the drawer slot. The drawer unit 3 can be pulled out between the upper partition plate 1 and the lower partition plate 2, and under the action of the anti-falling hook 4 and the tension spring 5, the maximum pulling-out degree can be controlled. When cleaning is required, the abutment between the hook body part 41 of the anti-falling hook 4 and the baffle 6 is released, and thus the drawer unit 3 can be directly pulled out of the cabinet body.

[0041] The present utility model has been described exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above-mentioned manner. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
