Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage draw-out safety switch cabinets, and more particularly to a low-voltage draw-out safety switch cabinet. Background Art

[0002] Low-voltage withdrawable safety switchgear is widely used in power systems. It uses a drawer housing to protect and isolate circuits. However, this type of switchgear suffers from a technical issue: the drawer housing cannot effectively control the damping force. This issue seriously impacts safety and creates risks during operation.

[0003] Specifically, existing low-voltage withdrawable safety switchgear has certain design limitations. Such switchgear typically consists of a drawer housing, a damping mechanism, an operating mechanism, and electrical connections. However, due to design limitations, the drawer housing cannot effectively control the damping force during operation, potentially generating excessive impact force or excessive speed during withdrawal, posing a safety threat to the operator. This suboptimal damping control presents a safety hazard during operation of low-voltage withdrawable safety switchgear, compromising its safety. Utility Model Content

[0015] (3) Beneficial effects

[0016] Compared with the existing technology, the present invention provides a low-voltage withdrawable safety switch cabinet with the following beneficial effects:

[0017] 1. The design of the adjustment mechanism enables flexible control of the damping force of the low-voltage withdrawable safety switchgear, improving the safety of operation. By changing the position of the top rod, the friction between the elastic plate and the inner wall of the cabinet can be adjusted, thereby changing the damping force. This design allows the operator to adjust the pulling force of the pull-out shell according to actual needs, ensuring the smoothness and safety of operation.

[0018] 2. The clamping mechanism achieves precise control of the position of the push rod through the cooperation of the push plate, the insert block and the limit sleeve. The one-way piece is clamped in the annular groove, so that the insert block can stably contact the middle plate, thereby completing the adjustment of the push rod position. This design makes the damping force adjustment of the switch cabinet more precise and improves the accuracy and efficiency of the operation. The use of the clamping mechanism not only simplifies the adjustment process, but also enhances the overall stability of the switch cabinet.

[0019] 3. The unlocking mechanism realizes the rapid release of the connection between the one-way plate and the annular groove by setting the unlocking sleeve and the follower plate. When it is necessary to adjust the damping force or perform maintenance, the push sleeve can be easily pushed to make the unlocking sleeve contact the one-way plate, thereby unlocking the connection between the two. This design makes the maintenance and adjustment of the switch cabinet more convenient, reduces the operation time, and improves the work efficiency. The use of the unlocking mechanism not only improves the flexibility of the switch cabinet, but also enhances the reliability and durability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

A spring 9 is sleeved on the push rod 7. , the spring 9 abuts against the fixed sleeve 5, the clamping mechanism includes a push plate 10, an insert block 11 and a limit sleeve 12, the limit sleeve 12 is installed in the fixed sleeve 5, a plurality of insert blocks 11 are provided, and the plurality of insert blocks 11 are respectively installed on the push plate 10, and the plurality of insert blocks 11 are respectively slidably connected to the limit sleeve 12, an intermediate disk 13 is provided on the push rod 7, and the plurality of insert blocks 11 respectively abut against the intermediate disk 13, a plurality of one-way pieces 14 are provided on the side wall of the fixed sleeve 5, a plurality of annular grooves 15 are opened on the side wall of the insert block 11, and the plurality of one-way pieces 14 are respectively stuck in the annular grooves 15, a plurality of push springs 16 are provided in the fixed sleeve 5, and an insert sleeve 17 is provided on the push spring 16, and the plurality of insert blocks 11 are respectively inserted into the insert sleeve 17.

[0030] In this embodiment, when the damping force needs to be adjusted, the position of the top rod 8 is first changed so that the top rod 8 can be made to contact the movable end of the elastic plate 4. Since the other end is in a fixed state, the friction between the elastic plate 4 and the inner wall of the cabinet 1 will change, thereby changing the damping force. Then the pulling force of each pull-out shell 2 can be adjusted, thereby completing the adjustment process.

[0031] See also Figure 4 , as an implementation method of the untying mechanism: the untying mechanism includes an untying sleeve 18 and a follower plate 19, a plurality of follower plates 19 are provided, and the plurality of follower plates 19 are respectively installed on the untying sleeve 18, the untying sleeve 18 is slidably connected to the plurality of insertion blocks 11, the plurality of insertion blocks 11 are provided with a push sleeve 20, the push sleeve 20 is provided with a compression spring 21, and the compression spring 21 abuts against the limit sleeve 12.

[0032] More specifically, when it is necessary to change the position of the push rod 8, first press on the push plate 10, and then the one-way piece 14 can be stuck in different annular grooves 15, and then the insertion block 11 is pressed on the intermediate disk 13, thereby completing the position adjustment of the push rod 8.

[0033] In summary, when the overall equipment is in use or running: when it is necessary to adjust the damping force, first change the position of the push rod 8, so that the push rod 8 can be made to contact the movable end of the elastic plate 4. Since the other end is in a fixed state, the friction between the elastic plate 4 and the inner wall of the cabinet 1 will change, thereby changing the damping force. Then the pulling force of each pull-out shell 2 can be adjusted, thereby completing the adjustment process. When it is necessary to change the position of the push rod 8, first press on the push plate 10, and then the one-way piece 14 can be stuck in different annular grooves 15. Then, because the insertion block 11 is pressed on the intermediate disk 13, the position adjustment of the push rod 8 is completed. When it is necessary to release the connection between the one-way piece 14 and the annular groove 15, first push the push sleeve 20 so that the unlocking sleeve 18 is pressed against the one-way piece 14, and then release the connection between the one-way piece 14 and the annular groove 15.
