Abstract

A chassis vehicle used for a switchgear includes a crossbeam, a leading screw, a vehicle frame, a lock plate and a lock pin. The leading screw includes a lock part. The vehicle frame is screwed to theleading screw. The lock plate can slide along the crossbeam, and a leading screw control hole and a lock plate control hole are formed in the lock plate. The leading screw control hole includes a leading screw unlock hole section and a leading screw lock hole section. The lock plate control hole includes a lock plate lock hole section and a lock plate unlock hole section. The lock pin passed through the lock plate control hole and has a lock block part and a passing part. Under the condition that the lock plate is in a lock position, the lock block part inserts into the lock plate lock hole section, the lock part inserts into the leading screw unlock hole section, and the vehicle frame is allowed to be extracted; under the condition that the lock plate is in an unlock position, the passing part inserts into the lock plate lock hole section, the lock part inserts into the leading screw unlock hole section, and the vehicle frame is prevented to be extracted. The chassis vehicle has advantages of simple structure, convenient production and convenient assembling. The invention also provides a switchgear of the chassis vehicle.

Description

technical field [0001] The invention relates to a chassis vehicle, in particular to a chassis vehicle used for a switch cabinet. The invention also relates to a switchgear comprising the above-mentioned chassis vehicle. Background technique [0002] As the moving part of the circuit breaker located in the switch cabinet, the chassis must have the function of restricting and interlocking with the grounding switch of the switch cabinet to ensure safe operation. Usually, a chassis vehicle interlock assembly that can be used in conjunction with the grounding switch interlock assembly is provided in the chassis vehicle. The existing chassis vehicle interlock assembly has a complex structure, is inconvenient to produce and assemble, and has an unstable linkage function. Contents of the invention [0003] The purpose of the present invention is to provide a chassis vehicle, which has a simple structure, is convenient for production and assembly, and has a more stable linkage fun...
