Detailed Description
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Referring to fig. 1-4, an embodiment of the present utility model is provided: the brake separating mechanism of the high-voltage switch mechanism comprises a first side plate 1 and a second side plate 2, and a brake separating mechanism body 3 arranged between the first side plate 1 and the second side plate 2; the brake release mechanism body 3 comprises a support frame 30 rotatably arranged between the first side plate 1 and the second side plate 2; the support frame 30 is also provided with a support seat 31, and a latch 37 is rotatably arranged on the support seat 31; the detent 37 is also provided with a step surface 39 and is contacted with cams inside the two side plates through the step surface 39.
In summary, the step surface 39 contacts the cams inside the two side plates. The stress point of the latch 37 can be changed, namely the wall thickness of the stress point is enlarged, so that the problem of cracking caused by the stress defect of the thin wall can be changed, and the service life and the quality of the latch are ensured.
Meanwhile, as the pawl 37 is rotatably mounted on the supporting seat 31, the dismounting of the pawl 37 is simple and convenient, and the instant impact of the cam on the pawl 37 is buffered by utilizing the rotation of the pawl 37 on the supporting seat 31.
Further, since the pin hole 310 is further provided on the latch 37, and the latch 37 is rotatably mounted on the support 31 after the provided pin shaft 32 passes through the support 31 and the pin hole 310, the latch 37 can be reliably rotated on the support 31.
Furthermore, since the mounting groove 33 is further provided on the supporting seat 31, and one end of the pawl 37 rotates in the mounting groove 33, the movement of the pawl 37 is limited by two sides of the pawl 37 on the side of the mounting groove 33, so that the pawl 37 can only rotate in a directional manner, that is, the shaft pin 32 is used as a rotation shaft to swing up and down, in addition, when the pawl 37 contacts with the lower bottom surface of the mounting groove 33, the pawl 37 can be limited to continue to rotate, so that the stability of the pawl 37 is further improved while buffering impact during working.
In order to enlarge the contact area between the detent 37 and the cam, so that the detent 37 can stably support the cam, the detent 37 is also provided with an arc groove 38.
On the basis of the above scheme, since the two ends of the supporting frame 30 are respectively provided with a supporting shaft 34, and the supporting shafts 34 are connected with the first side plate 1 and the second side plate 2 through shaft sleeves 36. Thus, the support frame 30 is supported and the support frame 30 is also convenient to rotate on the two side plates.
Further, a collar 35 is further provided on the outer wall surface of the support shaft 34, and the support shaft 34 is connected to the shaft sleeve 36 through the collar 35, so that the wear speed of the support shaft 34 can be reduced by rotating the collar 35 in the shaft sleeve 36.
In summary, the support frame 30 can rotate stably and reliably between the two side plates, and particularly, when the collar 35 and the shaft sleeve 36 are made of copper, the noise generated during the rotation between the support frame 30 and the two side plates can be reduced while avoiding the rapid wear of the support frame 30.
The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
