Description
Technical Field
The invention belongs to the technical field of low-voltage circuit breakers, and particularly relates to a universal low-voltage circuit breaker with a main shaft separated from an operating mechanism and fixed on a bakelite piece.
Background
The main shaft of the conventional universal low-voltage circuit breaker is assembled with the operating mechanism body, and the main shaft is arranged on a side plate of the operating mechanism body through a bearing bush or a bearing, so that the structure has a large load on the side plate of the operating mechanism body, and the side plate plays an important role in the performance of the operating mechanism body of the universal low-voltage circuit breaker. The outward force of main shaft acts on the curb plate when the circuit breaker divides and shuts, can arouse the deformation of curb plate and destroy even, leads to operating device's whole function to become invalid, and the curb plate after the deformation can make the main shaft take place skew moreover, leads to each contact resistance size after closing a floodgate to differ, influences its electric life. Therefore, reasonable improvement is needed to improve the service life of the universal low-voltage circuit breaker.

The technical problem to be solved by the invention is as follows: the main shaft is separated from the side plate of the operating mechanism body and is arranged on the bakelite part, so that the service life of the operating mechanism body is prolonged.
In order to solve the technical problem, the technical scheme of the invention provides a universal low-voltage circuit breaker with a main shaft separated from an operating mechanism, which comprises the main shaft, an operating mechanism body and a bakelite piece, and is characterized in that the main shaft and the operating mechanism body are respectively arranged on the bakelite piece, the main shaft is connected with the bakelite piece through a bearing and a bearing seat, a swing arm is arranged on the main shaft, a brake-separating spring shaft on the operating mechanism body passes through a shaft hole on the swing arm to connect the main shaft with the operating mechanism body, a brake-separating spring shaft sleeve is arranged outside the brake-separating spring shaft, the brake-separating spring shaft sleeve is slightly shorter than the brake-separating spring shaft, one end of a brake-separating spring is connected with the brake-separating spring shaft sleeve, and the other end of the brake-separating spring is connected with a second shaft on the operating mechanism body; the curb plate and the bakelite spare of operating mechanism body are connected, and the one side of being connected with the bakelite spare on the curb plate is equipped with the notch in order to avoid interfering with the main shaft.
Preferably, the two ends of the main shaft are respectively provided with a hoop, and the hoops clamp the two ends of the main shaft and are connected with the bakelite part.
The invention has the beneficial effects that: the main shaft is independently installed on the bakelite part and separated from the side plate of the control mechanism body, and firstly, the precision of the main shaft can be independently detected before installation, so that the mixed use of unqualified parts is avoided. Secondly, the outward force of the main shaft does not act on the side plate but acts on the bakelite part, thereby prolonging the service life of the operating mechanism body and being convenient for maintaining and replacing the operating mechanism body.

Detailed Description
In order to make the invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The invention relates to an universal low-voltage circuit breaker with a main shaft separated from an operating mechanism, which comprises a main shaft 3, an operating mechanism body 10 and a bakelite part 1, wherein the main shaft 3 and the operating mechanism body 10 are respectively arranged on the bakelite part 1, the main shaft 3 is connected with the bakelite part 1 through three sets of bearings and bearing seats 5, two ends of the main shaft 3 are respectively provided with an anchor ear 9, the anchor ears 9 clamp two ends of the main shaft 3 and are connected with the bakelite part 1, and a swing arm 4 is welded on the main shaft 3; the opening spring shaft 8 on the operating mechanism body 10 penetrates through a shaft hole on the swing arm 4 to connect the main shaft 3 with the operating mechanism body 10, an opening spring shaft sleeve 11 is sleeved outside the opening spring shaft 8, the opening spring shaft sleeve 11 is slightly shorter than the opening spring shaft 8, one end of an opening spring 12 is sleeved on the opening spring shaft sleeve 11, and the other end of the opening spring is sleeved on a second shaft 6 on the operating mechanism body 10; the side plate 2 of the operating mechanism body 10 is connected with the bakelite 1, and a notch is formed in one side of the side plate 2 connected with the bakelite 1 to avoid interference with the main shaft 3.
The assembly mode of the invention is different from the traditional universal low-voltage circuit breaker in that: the main shaft 3 and the operating mechanism body 10 of the traditional universal low-voltage circuit breaker are integrated when the operating mechanism body 10 of the traditional universal low-voltage circuit breaker is assembled, but the main shaft 3 and the operating mechanism body 10 of the invention are separated, because the opening spring shaft 8 needs to penetrate through the swing arm 4 welded on the main shaft 3, the opening spring shaft 8 cannot be installed in the operating mechanism body 10 firstly, therefore, compared with the traditional product, the invention adds the opening spring shaft sleeve 11, the opening spring shaft sleeve 11 is slightly shorter than the opening spring shaft 8, and does not need to penetrate through the swing arm 4, so that the opening spring shaft 8 can be installed in advance to replace the opening spring shaft 8 to provide a preloading force for the opening spring 12.
When the operating mechanism body 10 and the main shaft 3 are assembled with the bakelite part 1, the main shaft is firstly installed on the bakelite part 1 through the bearing, the bearing seat 5 and the hoop 9, the operating mechanism body 10 needs to be provided with the installation clamp 7 on the side plates 2 at two sides, the installation clamp 7 props against the opening spring shaft sleeve 11 to align the hole of the opening spring shaft sleeve 11 with the hole of the swing arm 4, then the opening spring shaft 8 penetrates through the hole of the swing arm 4 and the hole of the opening spring shaft sleeve 11 to assemble the main shaft 3 and the operating mechanism body 10 together, and the installation clamp 7 is taken down after the assembly is completed.
The main shaft is independently arranged on the bakelite part and separated from the side plate of the control mechanism body, so that the service life of the universal low-voltage circuit breaker is prolonged, and the control mechanism body is convenient to maintain and replace.
