[0025] refer to Figures 1 to 6 According to a preferred embodiment of the present invention, a low-voltage withdrawable switchgear with protective function is provided. It should be noted that the structure of the low-voltage withdrawable switchgear with protective function is as follows: Figure 1 As shown, it includes a box body 10, which is welded from multiple profile plates. The box body 10 has a first opening and a first cavity 101. The first opening communicates with the first cavity 101, and multiple first partitions 20 are fixed inside the first cavity 101. The multiple first partitions 20 are spaced apart and arranged vertically, as shown in the diagram. Figure 2 As shown. It is worth mentioning that there are two first partitions 20 on the same side, that is, they are located on the front and rear sides of the box body 10.

[0026] It should also be noted that the low-voltage withdrawable switchgear with protective function further includes multiple cabinet bodies 30, each of which cooperates with multiple first partitions 20. Notably, each cabinet body 30 is slidably mounted on its corresponding first partition 20. Furthermore, as... Figure 1 and 2 As shown, each cabinet body 30 has a second opening and a second cavity 301 on its top. The second opening is connected to the first cavity 101 and the second cavity 301 respectively. When the cabinet body 30 is pulled out, the second opening is connected to the outside. In addition, the components of the pull-out switch cabinet are placed in the second cavity 301 and the first cavity 101.

[0027] Specifically, the low-voltage withdrawable switchgear with protective function also includes multiple handle assemblies 40, which are respectively engaged with multiple cabinet bodies 30. Each handle assembly 40 includes a first handle 41 and a second handle 42. The first handle 41 and the second handle 42 are arranged opposite to each other and spaced apart by a predetermined distance. Both the first handle 41 and the second handle 42 are fixed to the outer wall of the corresponding cabinet body 30.

[0028] It should be noted that the first handle 41 has a protrusion 411, which is fixed to the wall of the cabinet body 30. The protrusion 411 has a first insertion hole, and the outer wall of the cabinet body 30 also has a second insertion hole. The second insertion hole corresponds to the first insertion hole and is also connected to the second cavity 301.

[0029] It is worth mentioning that each of the handle assemblies 40 includes a pressing rod 43, which has an insertion part and a supporting part. The insertion part is connected to the supporting part, and the insertion part passes through the first insertion hole and the second insertion hole in sequence and is placed in the second cavity 301. It should be noted that the first insertion hole is implemented as a stepped hole, and the supporting part is spaced at a predetermined distance from the stepped surface of the first insertion hole.

[0030] Furthermore, each of the handle assemblies 40 includes a first elastic member 44, which is disposed within the first insertion hole. One end of the first elastic member 44 abuts against the stepped surface of the first insertion hole, and the other end abuts against the end of the abutment portion facing the insertion portion. That is, the first elastic member 44 applies a force to the abutment portion of the pressing rod 43, causing the pressing rod to move away from the first insertion hole. It should also be noted that a limiting baffle 100 is fixed to the end of the insertion portion located in the second cavity 301. The limiting baffle 100 is configured to limit the position of the pressing rod 43 to prevent the pressing rod 43 from disengaging from the first insertion hole.

[0031] It should be noted that a second partition 200 is also fixed near the wall of the handle assembly 40 to form the second cavity 301, and each handle assembly 40 also includes a limiting component 45, one end of which cooperates with the second partition 200, and the other end is located at the bottom of the cabinet body 30.

[0032] Specifically, the bottom wall forming the second cavity 301 also has a limiting groove 302. The bottom of the limiting component 45 cooperates with the limiting groove 302 to limit the position of the cabinet body 30. Specifically, in the initial state, when the cabinet body 30 moves outward, the bottom of the limiting component 45 will abut against the first partition 20 located on the same side, so that the cabinet body 30 will not be pulled out.

[0033] The limiting component 45 includes a limiting plate 451 and a guide post 452. One end of the guide post 452 is fixed to the bottom of the second partition 200, and the top of the limiting plate 451 has a connecting hole. The other end of the guide post 452 is movably engaged with the connecting hole; specifically, the diameter of the connecting hole is larger than the cross-sectional diameter of the guide post 452. Furthermore, the limiting component 45 also includes a second elastic element 453, which is sleeved on the guide post 452. One end of the second elastic element 453 abuts against the bottom of the second partition 200, and the other end abuts against the top of the limiting plate 451. Additionally, it should be noted that in the initial state, the bottom of the limiting plate 451 always abuts against the bottom wall forming the second cavity 301, and the bottom of the limiting plate 451 also has a stop block 4511. The stop block 4511 passes through the limiting groove 302 and is located at the bottom of the cabinet body 30. It is configured to contact the corresponding first partition 20 to limit the position of the limiting plate 451. Furthermore, as... Figure 6As shown, the limiting plate 451 is movable in a manner in which it has a plurality of evenly distributed waist-shaped grooves 45102, and each of the waist-shaped grooves 45102 is provided with a threaded component to limit the position of the limiting plate 451 so that the limiting plate 451 can move up and down a predetermined distance.

[0034] It should be noted that the limiting plate 451 also has a pressure groove 45101. The pressure groove 45101 is implemented as an inclined groove, and the end of the insertion part placed in the second cavity 301 is directly opposite the pressure groove 45101. That is, when the pressure rod is squeezed, the insertion part will squeeze to form the top wall of the pressure groove 45101, so that the limiting plate 451 moves upward a predetermined distance. At this time, the stop block 4511 will retract into the limiting groove 302. At this time, the stop block 4511 will not interfere with the first partition 20, thereby allowing the user to pull out the cabinet body 30.

[0035] In summary, the low-voltage withdrawable switchgear with protective function described in the embodiments of this application is explained, which provides advantages such as self-locking, simple structure, and high practicality for the low-voltage withdrawable switchgear with protective function.

[0036] It is worth mentioning that, in the embodiments of this application, the low-voltage withdrawable switchgear with protective function has a simple structure, does not involve complex manufacturing processes or expensive materials, and has high economic efficiency. At the same time, for manufacturers, the low-voltage withdrawable switchgear with protective function provided in this application is easy to produce and has low cost, which is more conducive to controlling production costs and further facilitates product promotion and use.
