[0029] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0030] Embodiment 1

[0031] Please refer to Figures 1 to 5 As shown, a KYN cabinet trolley manual priority structure includes a trolley door 1, a tension spring 4, a travel switch 5, a push plate 3, a limit plate 7 and a chassis car bumper 2;

[0032] A chassis truck operation hole 101 is provided at the lower part of the hand door 1. The limit plate 7 is fixedly connected to the inner side of the hand door 1. A first hanging lock member 701 protruding outward is provided on one side of the outer surface of the limit plate 7. The first hanging lock member 701 passes through the chassis truck operation hole 101 and is located on one side of the chassis truck operation hole 101. The chassis truck bumper plate 2 is fixed to the inner side surface of the limit plate 7. A channel for the push plate 3 to move is provided between the chassis truck bumper plate 2 and the limit plate 7. The channel is communicated with the chassis truck operation hole 101. One side of the push plate 3 is movably connected to the channel. A second hanging lock member 302 protruding outward is provided at one end of one side of the push plate 3. The second hanging lock member 302 moves within the range of the chassis truck operation hole 101. A holding member 301 bent inward is provided at the other end of the other side of the push plate 3. The tension spring 4 is connected between the holding member 301 and the chassis truck bumper plate 2. The travel switch 5 is located above the bottom inside the hand door 1. An electrical interlock is provided between the travel switch 5 and the power supply of the electric chassis truck.

[0033] In this embodiment, a switch mounting plate 6 is further included;

[0034] The switch mounting plate 6 is fixed to the top surface of the bottom inside the hand door 1. The travel switch 5 is fixed to the top of the switch mounting plate 6.

[0035] In this embodiment, a hanging lock plate 8 is further included;

[0036] The hanging lock plate 8 is provided with a through hole adapted to the chassis truck operation hole 101. The hanging lock plate 8 is fixed to the outside of the hand door 1, and the position of the through hole coincides with the position of the chassis truck operation hole 101, which can play a role in protecting the chassis truck operation hole 101 to a certain extent.

[0037] In this embodiment, a connecting member 201 protruding inward is provided on the inner side of the chassis truck bumper plate 2. The tension spring 4 is connected between the holding member 301 and the connecting member 201.

[0038] In this embodiment, the shape of the limit plate 7 is in a U shape, so as to form a channel for the push plate 3 to move between the limit plate 7 and the chassis truck bumper plate 2.

[0039] The working principle of the utility model is that an electrical interlock is provided between the travel switch and the power supply of the electric chassis vehicle. In the initial state, the push plate 3 is affected by the tension of the tension spring 4, and the second padlock 302 at one end of the push plate 3 fits with the first padlock 701 on the limit plate 7, which can be used to hang a five-protection padlock. The abutment 301 at the other end of the push plate 3 abuts against the switch button of the travel switch 5. The travel switch 5 is in a closed state, and the circuit breaker trolley can be remotely controlled to perform various remote operations such as shaking in and out. When the switch cabinet equipment is repaired, the five-protection padlocks on the lock holes of the first and second padlocks 302 need to be removed, and the push plate 3 is manually pushed to make its abutment 301 away from the switch button of the travel switch 5. Under the continuous action of the manual thrust, the travel switch 5 is in a disconnected state, and the circuit breaker trolley cannot be remotely controlled to perform related operations. When the manual operation is completed, the manual thrust on the push plate 3 disappears, and the abutment 301 at the other end of the push plate 3 resumes abutting against the switch button of the travel switch 5, and the travel switch 5 returns to the closed state. At this time, the circuit breaker trolley can be remotely controlled again.

[0040] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
