Description

Technical Field

[0001] The utility model relates to a switch cabinet, in particular to a switch cabinet with an emergency tripping device for preventing accidental touch. Background Art

[0002] A switch cabinet is a conventional electrical equipment. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, circuit breakers, various AC contactors and other devices. The emergency tripping device can trip the circuit breaker inside the switch cabinet. In order to prevent accidental contact, a connecting frame is generally set on the outside of the push rod. When performing the tripping operation, the connecting frame needs to be set between the circuit breaker and the push rod; however, the existing tripping device causes the connecting frame to be easily offset during the tripping operation, thereby affecting the tripping effect; when the emergency device is tripped, there is also the hidden danger of personnel accidentally opening the cabinet door and causing misoperation. Utility Model Content

[0003] In order to solve the problems mentioned in the above background technology, a switch cabinet with an anti-accidental-touch emergency tripping device is proposed. The tripping is achieved by turning the knob 90° counterclockwise and pressing the guide rod to ensure that the emergency tripping operation can only be performed when the circuit breaker cabinet door is in the closed state.

[0004] The technical solution of the present utility model is a switch cabinet with an emergency tripping device to prevent accidental touching, characterized in that it includes a cabinet body, an emergency tripping button and an emergency tripping device, the cabinet body includes a cabinet door, the emergency tripping device includes a knob and a main body, the main body is rotatably connected to the knob, the main body includes a guide rod, the main body is parallel to the cabinet door, when the knob is rotated 90° counterclockwise relative to the cabinet door, it drives the main body to rotate axially perpendicular to the cabinet door, at this time the main body is on one side of the emergency tripping button, and the guide rod is abutted against the emergency tripping button by pressing the knob.

[0005] Preferably, a pressure plate is provided on the side of the emergency trip device close to the knob, and the pressure plate is located above the guide rod.

[0006] Preferably, the pressure plate is slidably connected to a cover plate, and the cover plate is located below the guide rod. When the knob rotates counterclockwise relative to the cabinet door, the pressure plate can be driven by the cover plate to move in a direction away from the guide rod.

[0007] Preferably, the knob is located on the outside of the cabinet door, one side of the knob is engaged with a rotating member, the rotating member is located on the inside of the cabinet door, the rotating member includes a first push rod and a second push rod, and the first push rod is connected to the pressure plate.

[0008] Preferably, a clamping member is provided on one side of the pressure plate, and the clamping member is connected to the second push rod. When the pressure plate moves toward the clamping member, the clamping member is driven to connect between the cabinet door and the cabinet door panel.

[0009] Preferably, a rubber sleeve is provided on the side of the guide rod that contacts the emergency trip button.

[0010] Preferably, the emergency tripping device includes a cover body, and the cover body is connected to the guide rod via a spring.

[0011] Preferably, a nut is provided on the side of the guide rod away from the cover body, and the guide rod is connected to the main body through the nut.

[0012] Preferably, a circuit breaker status auxiliary device is connected to one side of the emergency tripping device for detecting abnormalities in the circuit breaker starting to trip.

[0013] Preferably, a universal wheel is provided at the bottom of the cabinet body, and a locking piece is provided on one side of the universal wheel for opening and closing the universal wheel.

[0014] Compared with the prior art, the present invention provides a switch cabinet with an anti-accidental-touch emergency tripping device, which has at least one of the following beneficial effects:

[0015] 1. The knob can only be pressed after it is turned 90° counterclockwise so that the pressure plate is away from the guide. At the same time, the pressure plate pushes the clamp between the cabinet door and the fixed plate during the knob rotation process, which can effectively prevent employees from opening the cabinet door by accidental touch, ensuring that the cabinet door can be opened in an emergency when it cannot be opened, thereby improving the reliability of operation.

[0016] 2. A pressure plate is provided above the guide rod. When the knob is turned, the pressure plate moves away from the guide rod, which also prevents the emergency stop trip device from popping out when an abnormality occurs, thereby improving product safety.

[0017] 3. A circuit breaker status auxiliary device is provided at one end of the emergency tripping device. The circuit breaker status auxiliary device is used to detect the cause of the circuit breaker tripping, thereby improving product reliability. BRIEF DESCRIPTION OF THE DRAWINGS
