In the embodiment of the present invention, as shown in fig. 1 to fig. 6, the switch cabinet with high stability includes a cabinet body 10, a first door body 20, a second door body 30 and a driving assembly 40. Wherein,

the cabinet 10 has a circuit breaker chamber 11, and a set of stationary contact seats (not shown) as a stationary contact device is fixed in the circuit breaker chamber 11, and the stationary contact seats have stationary contacts for incoming and outgoing lines to communicate with an external high-voltage power circuit. In addition to the circuit breaker compartment 11, the cabinet body 10 also has control compartments, bus bar compartments, cable compartments, etc., which are not shown one by one in the present embodiment since they are conventional designs of high-stability switch cabinets.

The first door 20 and the second door 30 are slidably disposed on the cabinet 10 to slide relative to each other to open and close the circuit breaker chamber 11. Specifically, when the first door body 20 and the second door body 30 are closed, the stationary contact seat in the circuit breaker chamber 11 can be isolated, and when the first door body 20 and the second door body 30 are opened, the circuit breaker handcart can conveniently enter and exit the circuit breaker chamber 11.

The driving assembly 40 includes a screw rod 41, a first slider 42, a second slider 43 and a driving member 44, wherein the screw rod 41 includes a first screw 411 and a second screw 412 extending along the sliding direction of the first door 20, and a gear 413 having two axial ends connected to the first screw 411 and the second screw 412 respectively. Specifically, the first screw 411 and the second screw 412 have opposite screw threads.

The first sliding block 42 is sleeved on the first screw 411 and is in threaded connection with the first screw 411, and the first sliding block 42 is connected with the first door body 20; the second slider 43 is sleeved on the second screw 412 and is in threaded connection with the second screw 412, and the second slider 43 is connected with the second door 30.

The driving member 44 includes a rack 441, and the rack 441 is slidably disposed on the side wall 12 of the cabinet 10 and is engaged with the gear 413.

Specifically, when the rack 441 slides, the gear 413 is driven to rotate, and further the first screw 411 and the second screw 412 are driven to rotate, and then the first slider 42 and the second slider 43 drive the first door body 20 and the second door body 30 to slide. Since the screw threads of the first screw 411 and the second screw 412 are opposite, when the rack 441 slides, the first door body 20 and the second door body 30 approach or move away from each other. Therefore, the first door body 20 and the second door body 30 can be driven to be opened and closed synchronously by the driving assembly 40.

It can be understood that, in the switch cabinet with high stability of the present application, the gear 413 is driven to rotate by the rack 441 of the driving part 44, and then the lead screw 41 is driven to rotate, and when the lead screw 41 rotates, the first slider 42 and the second slider 43 slide along with the lead screw, so as to drive the first door body 20 and the second door body 30 to slide, thereby realizing the synchronous opening and closing of the first door body 20 and the second door body 30. Therefore, according to the technical scheme of the application, the first door body 20 and the second door body 30 are driven to be opened and closed through the screw rod 41 sliding block structure, and compared with a switch cabinet which drives the valve through a link mechanism, the switch cabinet has the advantages that the door body is not easy to clamp and the stability of opening and closing the door body is good.

Further, the high-stability switch cabinet of the present application further includes a limiting member 50. The limiting member 50 is used for limiting the driving member 44 when the first door body 20 and the second door body 30 are opened, so as to maintain the opened state of the first door body 20 and the second door body 30.

It can be understood that, by limiting the driving member 44 by the limiting member 50, the opening state of the first door body 20 and the second door body 30 can be maintained, thereby facilitating the entry and exit of the circuit breaker handcart.

When the restriction of the driving member 44 is to be released, the plug 51 is simply pulled out of the restriction insertion groove 443. It can be understood that the driving member 44 is limited by the engagement of the latch 51 with the limiting insertion groove 443, which has the advantages of simple structure and convenience.

Specifically, in the present embodiment, the retaining slot 443 is disposed on the rack 441.

Further, the position limiting member 50 further comprises a driving spring 52, one end of the driving spring 52 is connected with the cabinet 10, and the other end of the driving spring is connected with a latch 51, and the latch 51 has a tendency to move towards the driving member 44 under the elastic force of the driving spring 52.

Specifically, when the latch 51 is aligned with the limit slot 443 of the driving member 44 during the process of opening the first door body 20 and the second door body 30, the latch 51 is inserted into the limit slot 443 by the driving spring 52, so as to automatically limit the driving member 44. It can be understood that the driving spring 52 is arranged to drive the latch 51, so that the driving member 44 can be automatically limited, and the opening state of the first door body 20 and the second door body 30 can be automatically maintained. Therefore, manual operation can be reduced, and the use by a user is facilitated.

Further, the position-limiting member 50 further includes a lever 53, one end of the lever 53 is connected to the plug 51, and the other end of the lever 53 extends from the plug 51 to the surface of the sidewall 12 of the cabinet 10.

Specifically, the user may dial the plug pin 51 through the lever 53 to remove the plug pin 51 from the retaining slot 443. It will be appreciated that this arrangement facilitates actuation of the stop 50 by the user, and thus is convenient for the user to use.

Further, the side wall 12 is provided with a sliding slot 10a, and the rack 441 is slidably connected to the sliding slot 10 a.

It can be understood that, by providing the sliding groove 10a on the side wall 12 for the sliding connection of the rack 441, it is not only beneficial to limit the sliding direction of the rack 441, but also beneficial to protect the rack 441, so as to prolong the service life of the rack 441.

In particular, the driving member 44 further comprises a handle 442, the handle 442 being provided at an end of the rack 441 facing away from the gear 413. It can be understood that, in particular, the user can drive the rack 441 to slide by the handle 442 to open or close the first door body 20 and the second door body 30. It can be understood that, by providing the handle 442 at an end of the rack 441 opposite to the gear 413, the user can conveniently drive the rack 441, thereby facilitating the user experience.

Further, the rack 441 is provided with a limit stopper 444, the handle 442 is rotatably connected to the rack 441, the handle 442 has a first state where the extending direction intersects with the rack 441 and a second state where the extending direction is parallel to the rack 441, and when the handle 442 is in the first state, the limit stopper 444 abuts against a side of the handle 442 facing the screw rod 41.

Specifically, when the user wants to open the first door 20 and the second door 30, the handle 442 may be rotated to the second state, and at this time, the limit stopper 444 abuts against a side of the handle 442 facing the screw 41 to limit the rotation angle of the handle 442, so that the user can drive the rack 441 through the handle 442. When the first door body 20 and the second door body 30 are in the closed state, the user may rotate the handle 442 to the first state so as to receive the handle 442. It can be understood that the handle 442 is rotatably connected to the rack 441, so that the handle 442 can be conveniently folded on the premise of meeting the convenience of driving the rack 441 by a user, and the space occupied by the handle 442 in a non-use state is reduced.

Further, the sidewall 12 is provided with an accommodating groove 10b, and the handle 442 is accommodated in the accommodating groove 10b in the second state. It can be understood that, by accommodating the handle 442 through the accommodating groove 10b, the space occupied by the handle 442 in the non-use state can be further reduced.
