Background

The universal circuit breaker is also called frame type circuit breaker, and is a mechanical switch electric appliance which can connect, bear and break the current under the normal circuit condition, and can also connect, bear and break the current for a certain time under the specified abnormal circuit condition. Conventional circuit breakers are used to distribute electrical energy and to protect lines and power equipment from overloads, undervoltages, short circuits, etc. The face guard of current universal circuit breaker is provided with the button that is used for realizing circuit breaker separating brake or combined floodgate, and current universal circuit breaker face guard includes face guard body, button, and the button adopts the buckle mode with the face guard body to be connected, because can produce the giant air pressure when the circuit breaker divides absolutely, when the button receives the giant air pressure, is rushed out in the face guard, produces the potential safety hazard. Meanwhile, the small buckle is a plastic piece, so that the small buckle is easy to break and damage due to aging or other artificial reasons, and the use is influenced.

Disclosure of Invention

An object of the utility model is to overcome prior art's defect, provide a simple structure, compact structure, dependable and stable performance's universal circuit breaker face guard.

In order to realize the purpose, the utility model adopts a universal circuit breaker mask, which comprises a mask body, two buttons for driving the circuit breaker to open or close, and a handle movably arranged in a handle groove on the mask body, the mask body is provided with a button groove, the mask body is provided with a button hole communicated with the button groove, the button comprises a button body, a pressure spring, a driving piece and a damping washer, wherein the pressure spring, the driving piece and the damping washer are arranged in a button groove and matched with the button body, the button body comprises a panel and a guide rod with a T-shaped section, the compression spring is sleeved on the guide rod, one end of the guide rod penetrates through the button hole and is connected to the panel through threads, the damping cushion is arranged between the guide rod and the inner wall of the mask body, the driving piece is in threaded connection with the other end of the guide rod, and one end of the driving piece is provided with a spherical driving part which is matched with the circuit breaker operating mechanism.

The beneficial effect of above-mentioned structure is: the guide bar of this button body designs into the T type, and guide bar and panel adopt threaded connection, thereby be convenient for the assembly of button body and face guard body, and set up between guide bar and the face guard body and damping shock-absorbing gasket, can avoid the button to rush out the face guard body because of atmospheric pressure, and driving piece and guide bar adopt the assembly of threaded connection mode, rotate the driving piece, the action stroke of adjustable this button, thereby the face guard body of the different specifications of this button adaptation, application range is more extensive. Therefore, the universal circuit breaker mask has the advantages of simple structure, compact structure and stable and reliable performance.

In particular, one end of the handle is arranged on the circuit breaker operating mechanism, and the other end of the handle is provided with an opening part extending outside the handle groove. Be provided with the opening part on the handle, the user of being convenient for takes out the handle fast, and the operation is more convenient.

Particularly, the inner wall of panel on correspond the one end department of pressure spring and be provided with the spacing groove, the button inslot correspond the other end department of pressure spring and be provided with the constant head tank, the both ends of pressure spring block respectively in spacing groove, constant head tank, and constitute the joint cooperation of pressure spring and face guard body, button body. The pressure spring clamps between panel and face guard body, and the pressure spring of being convenient for and the assembly of panel, face guard body assemble more conveniently, and can guarantee that the button can reliably reset, is favorable to improving this universal circuit breaker face guard reliability of work.
