[0014] The beneficial effects of the utility model include: a safety cabinet for preventing electric shock, in which when the door panel is opened by mistake by non-professionals, the pull rod loses the pressure of the door panel and moves forward under the action of the spring, driving the connecting rod and the hook plate to move forward, pushing the operating handle to flip forward, thereby disconnecting the circuit breaker and cutting off the circuit in the cabinet, avoiding the risk of electric shock due to mistaken operation; when operated by professionals, they first rotate the shaft before opening the door panel, use the cam to drive the connecting rod and the hook plate to flip up, avoiding the operating handle, and then open the door panel to avoid disconnection of the circuit breaker and ensure the normal operation of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a structural schematic diagram of the utility model;
[0016] Figure 2 yes Figure 1 A partial enlarged view of part A;
[0017] Figure 3 yes Figure 2 Schematic diagram of the structure after the middle link is flipped up. DETAILED DESCRIPTION
[0018] Combine the following Figure 1~Figure 3 The technical solution of the utility model is further illustrated by specific embodiments.
[0019] like Figure 1 and Figure 2 The electric shock protection safety cabinet shown includes: a cabinet body 1, a door panel 2, a pull rod 4, a spring 6, a connecting rod 13, a hook plate 14 and a circuit breaker 16. The door panel 2 is arranged on the front of the cabinet body 1, and a door lock 3 is arranged on the door panel 2 to improve safety.
[0020] A mounting frame 17 is provided in the cabinet 1, and the circuit breaker 16 is provided on the mounting frame 17 to control the main circuit in the cabinet 1. The circuit breaker 16 can be an air switch, and an operating handle 15 is provided on the circuit breaker 16. After the operating handle 15 is flipped forward, the circuit breaker 16 can be disconnected to cut off the power supply in the cabinet 1.
[0021] The pull rod 4 is horizontally arranged in the cabinet 1, with the front end of the pull rod 4 pointing to the inner side of the door panel 2, and the closed door panel 2 is used for position limiting. In this embodiment, a pad 5 is arranged at the front end of the pull rod 4, and the pad 5 can increase the contact area with the door panel 2 to avoid damage to the door panel 2.
[0022] The cabinet 1 is provided with a first guide sleeve 12 and a second guide sleeve 11 corresponding to the pull rod 4 at intervals in front and back to guide the pull rod 4 to move horizontally forward and backward. The first guide sleeve 12 and the second guide sleeve 11 are fixed in the cabinet 1 with screws 18, and the structure is stable.
[0023] The pull rod 4 is provided with a stop pin 7 located between the first guide sleeve 12 and the second guide sleeve 11. The spring 6 is provided on the pull rod 4 and located between the stop pin 7 and the second guide sleeve 11. The stop pin 7 is elastically supported by the spring 6, giving the pull rod 4 a driving force to move forward.
[0024] The connecting rod 13 is disposed at the tail end of the pull rod 4 and is located above the circuit breaker 16 so as to be flippable upwards. In this embodiment, a hinge 8 connected to the connecting rod 13 is disposed at the tail end of the pull rod 4 to allow the connecting rod 13 to flip upwards.
[0025] In order to realize the upward turning operation of the connecting rod 13, a rotating shaft 9 extending horizontally to the bottom of the connecting rod 13 is provided on one side of the cabinet 1. The axial direction of the rotating shaft 9 is perpendicular to the axial direction of the pull rod 4 and does not affect each other. The rotating shaft 9 is provided with a cam 10 located below the connecting rod 13, and the end of the rotating shaft 9 is provided with a rotating handle located outside the cabinet 1. Figure 3 As shown, the rotating shaft 9 is rotated by turning the handle to realize the rotation of the cam 10 and drive the connecting rod 13 to turn up.
[0026] The hook plate 14 is arranged at the tail end of the connecting rod 13 and extends downward to the rear of the operating handle 15. Figure 2 As shown, when the door panel 2 is opened by mistake by non-professionals, the pull rod 4 loses the pressure of the door panel 2 and moves forward under the action of the spring 6, driving the connecting rod 13 and the hook plate 14 to move forward, pushing the operating handle 15 to flip forward, thereby disconnecting the circuit breaker 16 and cutting off the circuit in the cabinet 1, avoiding the risk of electric shock due to mistaken operation.
[0027] like Figure 3 As shown, when a professional operates, he first rotates the shaft 9 before opening the door panel 2, and uses the cam 10 to drive the connecting rod 13 and the hook plate 14 to flip up to avoid the operating handle 15, and then opens the door panel 2 to avoid the disconnection of the circuit breaker 16, thereby ensuring the normal operation of the equipment in the cabinet 1.
[0028] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
