Embodiment Construction

[0017] The present invention as Figure 1-3 As shown, it includes a half shaft 1 and several switching plates 2 , the half shaft 1 is cylindrical, and one end of the switching plate 2 is sleeved on the half shaft 1 and connected with the half shaft 1 as a whole.

[0018] The above-mentioned "connected as one" structure is representatively described below with three specific embodiments:

[0019] The switching plate 2 and the half shaft 1 are connected as a whole through casting.

[0020] The switching plate 2 and the half shaft 1 are connected as a whole by welding.

[0021] Axle sleeves 3 and clamping nuts 4 are arranged between the half shaft 1 and the plurality of switching plates 2, and the plurality of shaft sleeves 3 are in one-to-one correspondence with the plurality of switching plates 2, and are connected with the half shaft 1 as a whole. The outer diameter of the shaft sleeve 3 decreases successively from the center to both sides;

[0022] The bushing 3 includes a...

Abstract

An integral circuit breaker semi-shaft relates to the field of circuit breaker structural parts, in particular to an improvement proposed for the semi-shaft therein. The structure is exquisite, the processing is convenient, the stability is good, and the quality of the half shaft can be effectively guaranteed under the premise of retaining the original functions. The switching plate and the half shaft are connected as a whole through casting. The switching plate and the half shaft are connected as a whole by welding. Axle sleeves and clamping nuts are arranged between the semi-shaft and several switching plates, the several shaft sleeves correspond to the several switching plates one by one, and are connected with the semi-shaft as a whole, and the outer diameters of the several shaft sleeves are from the center Decrease to both sides in turn; the bushing includes a clamping section, a supporting section and a threaded section that are successively adjacent and whose outer diameters are successively decreasing, the switching plate is sleeved outside the supporting section, and the clamping nut It is connected with the threaded section through threads. It has the characteristics of exquisite structure, high processing efficiency, stable structure and good overall quality.

Description

technical field [0001] The invention relates to the field of circuit breaker structural parts, and in particular to improvements proposed for the half shaft therein. Background technique [0002] Most of the half-shafts of circuit breakers in the prior art are as shown in a Chinese invention patent application titled "Processing Method of Universal Circuit Breaker Half-shaft" with application number "201410409532.0" published by the State Administration of Technology on January 7, 2015. , its actual production structure is as follows Figure 4 As shown, an annular groove for accommodating the switching plate is first opened on the body of the half shaft, and then a positioning hole is opened in the annular groove, so that the positioning between the half shaft and the switching plate is completed by a positioning bolt. [0003] However, after using this type of half shaft for a long time, people found that because the annular groove and the positioning hole are all set on th...
