[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-6A one-time insertion device for a low-voltage cabinet drawer includes an insertion body 1, which is installed inside the low-voltage cabinet drawer via a convenient mounting bracket 2. The insertion body 1 is provided with a mounting plate 11, which is installed in the mounting slot 23 of the convenient mounting bracket 2. The convenient mounting bracket 2 has an installation opening 24 at the mounting slot 23. Sliding brackets 3 are symmetrically and vertically arranged on both sides of the mounting slot 23 of the convenient mounting bracket 2. Sliding seats 4 are vertically slidably fitted on both sides of the sliding brackets 3. A limiting plate 44 is provided on the top of the sliding seat 4 to block the mounting plate 11. A dust cover 5 is provided between the limiting plates 44 on both sides to prevent the mounting plate 11 from falling off the convenient mounting bracket 2.

[0016] The mounting plate 11 has symmetrical first mounting holes 111 on both sides. The first mounting holes 111 ensure that the plug-in body 1 can still be installed on the low-voltage cabinet drawer even without the convenient mounting bracket 2.

[0017] In addition, the convenient mounting bracket 2 has a third mounting hole 22 symmetrically opened on both sides of the mounting slot 23. The convenient mounting bracket 2 has a second mounting hole 21 on the other side away from the third mounting hole 22 and the mounting slot 23. The second mounting hole 21 is used to install the convenient mounting bracket 2 onto the low-voltage cabinet drawer.

[0018] Furthermore, the sliding frame 3 includes a first sliding rod 32 and a second sliding rod 33. Mounting feet 31 are provided on the upper and lower sides of the first sliding rod 32 and the second sliding rod 33. The mounting feet 31 are installed at the third mounting hole 22. A sliding seat 4 is slidably fitted on the first sliding rod 32 and the second sliding rod 33. A spring 34 is provided on the first sliding rod 32 for pressing the sliding seat 4. The spring 34 prevents the sliding plate 41 from easily shifting.

[0019] Meanwhile, the sliding seat 4 includes a connecting rod 43, and a sliding plate 41 is symmetrically arranged at the bottom of the connecting rod 43. Each sliding plate 41 is provided with a sliding hole 42. The sliding plate 41 slides on the first sliding rod 32 and the second sliding rod 33. A limit plate 44 is provided at the top of the connecting rod 43.

[0020] In addition, the dust cover 5 has a receiving cavity 51, the connection end of the plug-in body 1 located outside the low-voltage cabinet drawer is set in the receiving cavity 51, the dust cover 5 has multiple wiring ports 52, and the top of the dust cover 5 is provided with a handle 53, which makes it easy to lift the entire dust cover 5 and the sliding seat 4.

[0021] In this embodiment, to save time spent disassembling the main body 1 when repairing a plug-in, a convenient mounting bracket 2 is installed. The convenient mounting bracket 2 is installed on the outer wall of the drawer of the low-voltage cabinet through the second mounting hole 21. When installing the main body 1, the dust cover 5 and the sliding seat 4 are lifted by the handle 53. The sliding plates 41 on both sides slide vertically on the first sliding rod 32 and the second sliding rod 33. During the sliding process, the spring 34 is squeezed, so that the limiting plate 44 no longer blocks the mounting port 24 and the mounting slot 23. Thus, the main body 1 can be inserted into the mounting port 24, so that the connecting end located inside the low-voltage cabinet drawer can enter the low-voltage cabinet drawer.

[0022] After the mounting plate 11 is installed into the mounting slot 23, the handle 53 can be released, the spring 34 releases its elastic potential energy, thereby resisting the sliding plate 41 and preventing it from moving upward. The limiting plate 44 locks the mounting plate 11, and the dust cover 5 rests against the top of the plug-in body 1. When disassembling and installing the plug-in body 1, only the dust cover 5 needs to be pulled up, without spending more time disassembling the fixing parts.

[0023] By setting the dust cover 5 between the two limit plates 44, its receiving cavity 51 can completely cover the electrical connection end of the plug body 1 exposed outside the drawer, effectively preventing the intrusion of dust and foreign objects, ensuring the cleanliness and safety of the electrical connection, and improving the long-term operational reliability of the plug.

[0024] The mounting plate 11 on the main body 1 can be quickly installed using the convenient mounting bracket 2, or it can be directly installed on the low-voltage cabinet drawer using the first mounting hole 111 on it. This design provides flexibility, allowing it to adapt to different installation needs and application scenarios.

[0025] The sliding seat 4 forms a stable sliding fit with the first sliding rod 32 and the second sliding rod 33 through the sliding plate 41 and the sliding hole 42, ensuring the smooth movement of the limiting plate 44. The continuous downward pressure provided by the spring 34 ensures that the limiting plate 44 firmly and reliably limits the mounting plate 11, preventing it from loosening under vibration or other conditions.

[0026] In this invention, by setting up a convenient mounting bracket 2, a sliding bracket 3 with a spring 34, and a sliding seat 4 that slides with it, the operator only needs to lift the handle 53 to move the dust cover 5 and the sliding seat 4 upwards to insert or remove the mounting plate 11 of the plug-in body 1 into or remove the mounting slot 23. After releasing, the restoring force of the spring 34 pushes the limiting plate 44 downwards and locks the mounting plate 11, completing the fixation. This process requires no tools, greatly simplifying the operation steps, improving maintenance efficiency, and realizing the quick installation and removal of the plug-in on the low-voltage cabinet drawer in one go.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
