Description

Technical Field

[0001] This utility model belongs to the technical field of electrical cabinet equipment, specifically relating to a novel drawer interlocking mechanism. Background Technology

[0002] A large interlocking mechanism, also known as a cross-lock or interlocking mechanism, is a type of mechanism installed between different drawers to ensure interlocking or interlocking between different circuits within the same distribution cabinet. Drawer interlocking mechanisms are safety protection devices used in low-voltage drawer-type switchgear. They primarily function as mechanical interlocking devices for the drawers, ensuring the safety of the equipment during maintenance or operation. By mechanically restricting drawer movement, they prevent accidental operation when the power supply is not completely disconnected or safety conditions are not met. For example, when a drawer is in the test position, the interlocking mechanism will lock other operating positions, avoiding the risk of live operation.

[0003] Existing drawer cabinets mostly use a simple rotating locking mechanism to prevent the drawers from sliding out. This locking mechanism has poor interlocking and is inconvenient for the operator. Therefore, we propose a new type of drawer interlocking mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a novel drawer interlocking mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel drawer interlocking mechanism includes a cabinet body, a drawer body located on the inner side of the cabinet body, a connecting block mounted on one inner surface of the cabinet body, a groove formed on the surface of the connecting block, a slider slidably mounted on the inner side of the groove, a heart-shaped slide rail formed on the surface of the slider, a sliding shaft slidably mounted on the inner side of the heart-shaped slide rail, a connecting rod slidably sleeved on the surface of the sliding shaft, one end of the connecting rod rotatably mounted on one side of the connecting block, a spring fixedly connected to one inner side of the groove, the other end of the spring fixedly connected to one side of the slider, and a top rod slidably passing through the inner surface of the groove, one end of the top rod fixedly connected to one side of the slider.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a novel drawer interlocking mechanism, including a cabinet body 1, a drawer body 4 on the inner side of the cabinet body 1, a connecting block 6 installed on one inner surface of the cabinet body 1, a groove 8 on the surface of the connecting block 6, a slider 9 slidably installed on the inner side of the groove 8, a heart-shaped slide rail 10 on the surface of the slider 9, a sliding shaft 12 slidably installed on the inner side of the heart-shaped slide rail 10, a connecting rod 13 slidably sleeved on the surface of the sliding shaft 12, one end of the connecting rod 13 rotatably installed on one side of the surface of the connecting block 6, a spring 14 fixedly connected to one inner side of the groove 8, the other end of the spring 14 fixedly connected to one side of the slider 9, a top rod 15 slidably passing through the inner surface of the groove 8, one end of the top rod 15 fixedly connected to one side of the slider 9, and a through opening at the bottom of the groove 8. There is a sliding hole 16, and a fixing block 17 is slidably inserted through the inner side of the sliding hole 16. The top of the fixing block 17 is fixedly connected to the bottom of the slider 9. A through hole 24 is opened on the bottom surface of the fixing block 17. Guide holes 18 are symmetrically opened through the two sides of the through hole 24. A sliding rod 23 is slidably connected to the inner side of the guide hole 18. Fixing rods 19 are symmetrically fixedly installed on the two sides of the bottom of the slider 9. The inner side of the fixing rod 19 is rotatably connected to one end of the connecting rod 20. One side of the sliding rod 23 extends into the interior of the through hole 24, and the end is rotatably connected to the fixing rod 19. The end of the sliding rod 23 extending into the interior of the through hole 24 is fixedly connected to the end of the connecting rod 20. A pull hook 21 is installed on one end of the connecting rod 20. A limit block 22 is installed on one bottom end of the drawer body 4.

[0021] Specifically, one side of the connecting block 6 is fixed to the inner surface of the cabinet 1 using screws 7.

[0022] Specifically, L-shaped slide rails 2 are symmetrically fixedly installed between the two inner surfaces of the cabinet 1. Slide rails 3 are slidably installed inside the L-shaped slide rails 2, and the top of the slide rails 3 is fixedly connected to the bottom of the drawer body 4.

[0023] Specifically, a handle 5 is fixedly installed on one side of the drawer body 4.

[0024] Specifically, the heart-shaped slide 10 has a slot 11 on one side and the guide hole 18 is set at an angle.

[0025] Specifically, a rubber sleeve 25 is fitted on the contact end face between the top rod 15 and the drawer body 4.

[0026] In this embodiment, the drawer body 4 is pushed into the cabinet 1 to contact the end rubber sleeve 25 of the top rod 15, and the compression of the top rod 15 causes the slider 9 to slide inside the slide groove 8, thereby compressing the spring 14. Figure 4 The original positions of connecting rod 13 and sliding shaft 12 are at the leftmost pad of the heart-shaped slide 10. When slider 9 slides to the left inside the slide groove 8, sliding shaft 12 will slide to the position of slot 11 inside the heart-shaped slide 10, thus limiting the sliding shaft 12. Simultaneously, as slider 9 moves, it will cause the bottom fixing block 17 to slide inside the slide hole 16. Figure 3 Because the guide hole 18 is inclined, when the fixing block 17 slides to the left, it will drive the slide rod 23 to move obliquely upward. Since the angle between the slide rod 23 and the connecting rod 20 is fixed, the upward movement of the slide rod 23 will drive the hook 21 at the end of the connecting rod 20 to move upward, thereby forming a locking effect between the limiting block 22 at the bottom of the drawer body 4, realizing the automatic fixing of the drawer body 4. Then, the drawer body 4 is pushed to the inside of the cabinet 1 again, and the sliding shaft 12 will move from the inside of the slot 11 to the other side of the heart-shaped slide 10, thus returning to the original position. The spring 14 will drive the mechanism to reset, so that the hook 21 at the end of the connecting rod 20 is separated from the limiting block 22, thereby realizing the automatic unlocking effect of the drawer body 4.
