[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 1 - Figure 8 As shown, this utility model provides a technical solution for a closing interlocking mechanism for a power distribution cabinet drawer, including a cabinet body 1, a cabinet cavity 2 arranged in a linear array on one side of the cabinet body 1, a drawer box 3 slidably connected inside the cabinet cavity 2, a box cavity 4 on the upper part of the drawer box 3, a controller 5 installed inside the box cavity 4, a connecting rod 6 on a rotary switch on one side of the controller 5, a turntable 7 fixedly connected to the end of the connecting rod 6, the turntable 7 rotatably connected to the front end of the drawer box 3, a first gear 8 fixedly sleeved on the outside of the connecting rod 6, a first rack rod 9 meshing with both sides of the first gear 8, a sliding groove formed in the inner wall of the cabinet cavity 2, the first rack rod 9 slidably connected in the sliding groove cavity, a pin fixedly connected to the front end of the first rack rod 9, and pin grooves 26 for insertion and connection with the pins on the top and bottom walls of the cabinet cavity 2.

[0027] Drawer box 3 is a drawer. When drawer box 3 is inserted into cabinet cavity 2, the plug 13 on drawer box 3 is connected to the main power socket 14. At this time, controller 5 is not turned on yet. Then, turntable 7 is rotated. Turntable 7 drives the rotary switch on controller 5 to rotate through connecting rod 6, thereby turning on controller 5. At the same time, turntable 7 also drives the first gear 8 to rotate. The first gear 8 drives the two first rack rods 9 to slide relative to each other and insert the pin into the cavity of pin groove 26, thereby locking drawer box 3. Conversely, turning the turntable 7 releases the locked state of drawer box 3 and disconnects the power to controller 5.

[0028] The controller 5, plug 13 and main power socket 14 used in this application are all purchased components. They are selected according to power and size requirements. The controller 5 and rotary switch system use modules provided by the corresponding vendors. This application will not elaborate further.

[0029] like Figure 6 As shown, a first spring is provided at the end of the first rack rod 9 away from the pin. The movable end of the first spring is fixedly connected to the inner wall of the sliding groove. A transparent plate is rotatably sleeved on the outer side of the connecting rod 6. The transparent plate is fixedly connected to the groove opening on one side of the sliding groove.

[0030] When the drawer 3 is in the locked state, the first spring is compressed by the first rack 9. When the operator releases the force applied to the turntable 7, the first rack 9 will return to its original position due to the spring force, and the turntable 7 will rotate back to its original position.

[0031] like Figure 4 and Figure 7 As shown, a handle 10 is fixedly connected to one side of the turntable 7. A limiting groove is opened at the front end of the handle 10, which passes through the turntable 7. A second gear 11 is rotatably connected in the limiting groove, and two second rack rods 12 are slidably connected. The two second rack rods 12 are respectively meshed with the two sides of the second gear 11. A second spring is provided between one end of the second rack rod 12 and the inner wall of the limiting groove. A limiting hole 25 is opened at the front end of the drawer 3, and the limiting hole 25 is inserted into the other end of the second rack rod 12.

[0032] The operator needs to hold the handle 10 and press the end of the protruding second rack rod 12 with his thumb. This second rack rod 12 uses the second gear 11 to drive another second rack rod 12 to slide out of the limiting hole 25, thereby releasing the locking state of the turntable 7. Then the turntable 7 can be rotated. At this time, the second rack rod 12 compresses the second spring.

[0033] After the turntable 7 is reset, the second rack rod 12 will be reset due to the elastic force of the second spring, and the corresponding movable end of the second rack rod 12 will be inserted into the limiting hole 25, thereby locking the turntable 7.

[0034] like Figure 2 and Figure 3 As shown, a plug 13 is provided at the rear end of the drawer 3, and the plug 13 is electrically connected to the controller 5. A main power socket 14 is provided on the inner wall of the cabinet cavity 2, and the main power socket 14 is electrically connected to the plug 13.

[0035] The main power socket 14 is electrically connected to the power supply.

[0036] like Figure 1 and Figure 8As shown, a sealing plate 15 is rotatably connected to the top wall at the opening of the cabinet cavity 2. Two track rods 16 are fixedly connected to the top wall inside the cabinet cavity 2. The track rods 16 are located above the drawer box 3. A slider 17 is slidably sleeved on the outside of the track rods 16. A rotating rod 18 is rotatably connected between the slider 17 and the movable end of the sealing plate 15. A third spring is provided between the slider 17 and the inner wall of the cabinet cavity 2. The third spring is slidably sleeved on the outside of the track rods 16.

[0037] After the drawer box 3 is removed from the cabinet cavity 2, the sealing plate 15 will rotate due to its own weight and the elastic force of the third spring, so that the sealing plate 15 is vertical and blocks the opening of the cabinet cavity 2.

[0038] After the drawer box 3 is placed into the cavity of the cabinet 2, the drawer box 3 pushes the movable end of the sealing plate 15 to rotate and reset, while the sealing plate 15 uses the slider 17 on the rotating rod 18 to compress the third spring.

[0039] like Figure 6 As shown, the connecting rod 6 includes a thick rod 601 and a thin rod 602. The thin rod 602 has a hexagonal cross-section. One end of the thick rod 601 has a hexagonal cavity that is slidably connected to the thin rod 602. One end of the thick rod 601 is fixedly connected to one side of the turntable 7. The other end of the thick rod 601 is slidably sleeved on one end of the thin rod 602. A movable plate 19 is rotatably sleeved on the outer side of the thin rod 602. The movable plate 19 is set on the inner wall of the box cavity 4. A connecting plate 20 is fixedly connected to the movable end of the thin rod 602. A connecting groove is opened on one side of the connecting plate 20. The connecting groove is adapted to the rotary switch.

[0040] like Figure 5 and Figure 6 As shown, a worm gear 21 and a worm 22 are rotatably connected to one side of the movable plate 19. A rocker arm is fixedly connected to the top of the worm 22. The worm gear 21 and the worm 22 are meshed with each other. A threaded rod 23 is fixedly connected to one side of the worm gear 21. A threaded tube 24 is threadedly sleeved on the movable end of the threaded rod 23. The threaded tube 24 is fixedly connected to the inner wall of the box cavity 4. A wire groove is formed on the inner wall of the box cavity 4. The wire groove is slidably connected to the movable plate 19. The cross-section of the wire groove is a convex-shaped cavity. A convex-shaped wire block is fixedly connected to the bottom of the movable plate 19. The wire block is slidably connected to the wire groove.

[0041] By rotating the worm gear 22, the worm gear 22 drives the threaded rod 23 to rotate via the worm wheel 21. The threaded rod 23 then drives the moving plate 19 to move via the threaded tube 24, thereby adjusting the length of the connecting rod 6. This allows the distance between the controller 5 and the turntable 7 to be adapted according to the installation position of the controller 5, so that the turntable 7 can drive the rotary switch on the controller 5 to rotate via the connecting rod 6.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
