DETAILED DESCRIPTION

[0017] In order to make the technical solution more clear to those skilled in the art, Figure 1 -4 Detailed description of the technical solution of the utility model:

[0018] A power box for an elevator with a novel locking mechanism comprises a front door 1, a rear shell 2 connected to the front door 1 by a hinge, a circuit breaker 3 arranged in the rear shell 2, a lock 4 arranged on the front door 1, a connecting buckle 5 arranged on the rear shell 2 and corresponding to the lock 4, and a socket 6 arranged on the upper side of the rear shell 2. When the cover is closed, the lock 4 is stuck under the connecting buckle 5, and the circuit breaker 3 is fixedly installed in the rear shell 2 by a terminal board. The lock 4 cooperates with the connecting buckle 5 to complete the opening and closing of the power box, which is convenient to operate and simple to use.

[0019] In order to observe the working status of the circuit breaker 3, a visual window 7 is provided on the front door 1 at a position corresponding to the circuit breaker 3, so that people can observe the working status conveniently.

[0020] The structure of the lock buckle 4 will be described in detail below. The lock buckle 4 includes a moving column 41, a moving block 42 arranged on the moving column 41, a clamping block 43 arranged on the moving block 42, a torsion spring 44 arranged on the moving block 42, and a positioning column 45 arranged on the front door 1. The torsion spring 44 is sleeved on the positioning column 45 and is clamped on the moving block 42. One end of the moving column 41 protrudes from the surface of the front door 1, and the other end of the moving column 41 is fixedly connected to the moving block 42. When the front door 1 is covered with the rear shell 2, the clamping block 43 presses against the positioning column 45. It is placed under the connecting buckle 5, and a runway-shaped groove is provided on the moving block 42 for installing the positioning column 45. When working, people press the moving column 41, and the moving column 41 drives the moving block 42 to move, thereby driving the clamping block 43 to disengage from the connecting buckle 5 and complete the opening state. Among them, due to the setting of the torsion spring 44 and the positioning column 45, after the pressing is completed and released, under the action of the torsion spring 44, the clamping block 43, the moving column 41, and the moving block 42 return to their original positions, which has a good use effect and is easy to operate. The runway-shaped groove and the positioning column 45 can limit the moving angle of the moving block 42.

[0021] More preferably, two locks 4 are provided and are symmetrically arranged on the front door 1 front and back.

[0022] In order to facilitate opening of the front door 1 after the front door 1 and the rear shell 2 are opened, a lifting plate 8 is provided between the two lock buckles 4 on the front door 1. The lifting plate 8 is fixedly mounted on the front door 1, and people can hold the lifting plate 8 to control the rotation of the front door 1.

[0023] Among them, the circuit breaker 3 includes a main switch area 31, a shaft lighting area 32, and a car lighting area 33. The windows on the front door 1 located in the shaft lighting area 32 and the car lighting area 33 are embedded with a flip cover 9. The open and closed states of the flip cover 9 can realize whether the external side can control the opening and closing of the circuit breaker 3 of the lighting part when the front door 1 is in a closed state; it can facilitate the operation control during the maintenance process of the lighting circuit. The internal control circuit breaker 3 is divided into a lighting part and an elevator power main switch control part. The elevator main switch control part is not operable unless it is necessary. The lighting circuit and the elevator main switch control are separate circuits and work independently. Under normal circumstances, they require frequent maintenance and repair; considering the convenience of the control operation of the lighting part, the operability of the circuit breaker 3 of the lighting part can be realized by flipping the cover 9 when the front door 1 is closed.

[0024] The socket 6 is also pin-connected with a socket cover plate to protect the socket 6 .

[0025] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
