Description
Technical field
The utility model relates to a kind of handle operation mechanism of isolating switch of low-voltage electrical apparatus, refers to that especially handle is provided with the operating mechanism of self-locking device.
Background technology
General isolating switch, include an operating mechanism and a stored energy mechanism, described operating mechanism generally includes operating grip and contact support, and the isolated location needs indication explanation in addition, described stored energy mechanism mainly is spring, when the needs insulating power supply, operating grip drives the contact support makes moving contact separately, and stored energy mechanism makes handle be in open position, and there is special indicated number isolating switch to be in open position, this mechanism is generally comparatively complicated, and parts size precision is had relatively high expectations, thereby the cost of product is also fine, fatigue can take place in spring in addition, influences the useful life of product.
In addition, also there is the isolating switch that stored energy mechanism is not set, it is the patent of 200720193959.7 the operating mechanism of insulating power supply " be used for " as the patent No., it is provided with snap portions and has contact with realization shell setting by handle, and both cooperate, guarantee that moving contact is in the demonstration of open position and fixing, such designs simplification use complexity that stored energy mechanism exists and the problem of demonstration, but have unsafe hidden danger: particularly operating personnel manually do not buckle when having contact with snap portions yet, run into handle easily and make its false switching, abnormally dangerous.
Summary of the invention
The utility model overcomes the problem that prior art exists, and a kind of novel handle operation mechanism that can automatically lock handle after isolating switch disconnects is provided
Realize above-mentioned purpose, the utility model adopts following technology: a kind of handle operation mechanism that is used in the band self-locking device on the isolating switch, include the hinged base of isolating switch and the insulated handle that covers of being arranged on, the inboard of described handle is provided with moving contact, it is characterized in that: the back side, the outside of described handle is provided with elastic component, this elastic component has the extended end of an end for stretching automatically along the Width of handle at least, elastic component is provided with one can press the forced section that extended end is resetted for instrument or hand, the base of described isolating switch or and cover and be provided with lockhole or the locked groove that can constitute lock fit with the extended end of elastic component, after the perk of isolating switch separating brake handle the extended end of elastic component stretch automatically slip into lockhole or locked groove constitute handle and base or and lid between automatically lock and cooperate.
By adopting such scheme, we can cooperate lock handle with lockhole or locked groove by the automatic stretching, extension of elastic component, so just can fine customer service the problem of the misoperation that exists in the prior art, improved the fail safe of isolating switch greatly, in release, need realize release by the artificial forced section of pressing elastic component painstakingly in addition, can solve other locking mechanism problem of unstable like this.
Further setting of the present utility model is: be respectively arranged with projection on the back side, the outside of described handle and on the both sides of broad ways, be respectively arranged with through hole on the projection, the whole archwise of described elastic component, two extended end of elastic component are straight pin, straight pin is located in the through hole, and the length of two straight pins is greater than the length of through hole, the base of described isolating switch and cover and be respectively arranged with lockhole, the straight pin of elastic component stretches automatically and constitutes handle automatically locking with base and between covering in the lockhole that slips into seat and lid and cooperate after the perk of isolating switch separating brake handle.
By adopting such scheme, elastic component is realized making locking more firm to the locking between base and the lid.
Of the present utility model further the setting again is: the other end that described handle is positioned at hinged end is provided with draw ring; Described base and covering has been wholely set protruding bow portion respectively, and described lockhole is arranged in the protruding bow portion.
By adopting such scheme, make product more convenient in the use, the effect that draw ring is set is the work that makes things convenient for handle.
Below in conjunction with drawings and embodiments the utility model is described further.

Specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, a kind of handle operation mechanism that is used in the band self-locking device on the isolating switch, include the hinged base 1 of isolating switch and the insulated handle 4 on the lid 3 of being arranged on, the inboard of described handle 4 is provided with moving contact, the back side, the outside of described handle 4 is provided with elastic component 2, as long as specifically satisfying elastic component 2 firmly is arranged on the handle 4, this elastic component 2 has the extended end 21 of an end for stretching automatically along the Width of handle 3 at least, elastic component 2 is provided with one can press the forced section 22 that extended end is resetted for instrument or hand, the base 1 of described isolating switch or and lid 3 be provided with lockhole 6 or the locked groove that can constitute lock fit with the extended end 21 of elastic component 2, after 4 perks of isolating switch separating brake handle the extended end 21 of elastic component stretch automatically slip into lockhole 6 or locked groove constitute handle 4 and base 1 or and lid 3 between automatically lock and cooperate.By adopting such scheme, we can cooperate lock handle with lockhole 6 or locked groove by the automatic stretching, extension of elastic component 2, so just can fine customer service the problem of the misoperation that exists in the prior art, improved the fail safe of isolating switch greatly, in release, need make extended end break away from lockhole 6 or locked groove by the artificial forced section of pressing elastic component 22 painstakingly in addition, the handle realization release of can turning round so effectively solves other locking mechanism problem of unstable.
In the utility model embodiment, be respectively arranged with projection 7 on the back side, the outside of described handle 4 and on the both sides of broad ways, be respectively arranged with through hole 71 on the projection 7, described elastic component 2 whole archwises, two extended end of elastic component 2 are straight pin 21, straight pin 21 is located in the through hole 71, and the length of two straight pins 21 is greater than the length of through hole 71, can guarantee that so straight pin 21 inserts lockhole 6 after aiming at through hole 71, in the present embodiment, more firm in order to lock, be respectively arranged with through hole 71 on the base 1 of described isolating switch and the lid 3, the straight pin 21 of elastic component stretches automatically to slip into seat 1 and cover to constitute handle 4 with base 1 and cover automatically locking between 3 in 3 the lockhole 6 and cooperates after 4 perks of isolating switch separating brake handle.
In the utility model embodiment, the other end that described handle 4 is positioned at hinged end is provided with draw ring 5, and setting is drawn, and 5 effect is the work that makes things convenient for handle.Be wholely set protruding bow portion 11,31 on described base 1 and the lid 3 respectively, described lockhole 6 is arranged in the protruding bow portion 11,31, and the entire product outward appearance is relatively coordinated rationally like this, and we also can not arrange protruding bow portion 11,31 certainly.
The utility model discloses, and is a kind of of preferred embodiment, and patent category of the present utility model is not all taken off in Ju Bu change or modification and come from technological thought of the present utility model and be easy to the person of knowing by inference by the people who has the knack of this technology such as.
