Therefore, the working efficiency is improved by 10 times.
Description
Technical field
The utility model relates to car switch moving contact tool specially for attaching and detaching.
Background technology
At present, the dismounting of the on-the-spot car switch moving contact of known electric operating, need to remove the constraint spring of moving contact, and car switch moving contact disassembles, and car switch moving contact is all whole buying.In actual use, the decomposition of car switch moving contact is lost time, and after decomposing, the pulling force of spring decreases, and can affect the clamping degree of moving contact and fixed contact, and serious even can cause the accident that contact is overheated.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of car switch moving contact tool specially for attaching and detaching, and this instrument is that steel wire loop the inside is inserted in the outside of car switch moving contact, back and forth moves action bars, steel wire loop is drawn little, shrink to the center of circle the outside of moving contact, and open outside the center of circle inboard of moving contact, and light and switch connecting rod departs from, whole operating process, car switch moving contact does not need to decompose, and does not change the clamping degree of spring, and operating efficiency improves 10 times.
The utility model solves the technical scheme that its technical problem adopts:
Car switch moving contact tool specially for attaching and detaching, include: tooth bar, gear box, gear, operating grip, front hock, rear hock, described gear is arranged in gear box by gear shaft, one end of operating grip is connected with gear shaft, the middle part of operating grip is provided with front hock connecting axle, one end of front hock is connected on front hock connecting axle, and the other end of front hock rides in the teeth of gear; Hock back-moving spring before overlapping on front hock connecting axle.One end of rear hock is connected with rear hock connecting axle, and the other end of rear hock rides on gear, and rear hock connecting axle is fixed in gear box.On rear hock connecting axle, overlapping rear hock back-moving spring, the front end of tooth bar 1 is through gear box, and gear is meshed with the tooth bar that is positioned at gear box, and the afterbody of tooth bar has cross bore, the two ends of steel wire rope are through a side that is connected to gear box after cross bore, and the afterbody of steel wire rope forms steel wire rope lasso trick.
One side of described gear box is provided with gear box side plate, and bolt with holes is installed on gear box side plate, and, through passing bolt with holes after cross bore, lock steel wire rope with locking nut at the two ends of steel wire rope again.
The beneficial effect that the utility model has is: the utility model is comprised of structures such as operating grip, gear, gear box, tooth bar, front hock, rear hock, steel wire loops, when dismounting is used, steel wire loop the inside is inserted in the outside of car switch moving contact, back and forth move action bars, steel wire loop is drawn little, and shrink to the center of circle the outside of moving contact, and open outside the center of circle inboard of moving contact, light and switch connecting rod departs from, and during installation, process in contrast.Whole operating process, car switch moving contact does not need to decompose, and does not change the clamping degree of spring.Operating efficiency improves 10 times.Having solved operation field does not in the past have specific purpose tool, completely manual problem of decomposing dismounting.Reasonable in design, guaranteed the fast assembling-disassembling of operation field.Increase work efficiency, improve repair quality.Operating grip back and forth operates, and in the time of need to unclamping, can a step gear box be back into starting point.Use simply, safe and reliable, do not need other aid.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the utility model working state schematic representation.
