Abstract
The invention discloses a circuit breaker draw bar, which comprises a draw bar body, wherein one end of the draw bar body is axially provided with a mounting hole. The circuit breaker draw bar is characterized in that the other end of the draw bar body is axially provided with an auxiliary hole opposite to the mounting hole. The circuit breaker draw bar has a simple technical scheme, and a problem that a shaft is difficult to disassemble can be solved by adding one auxiliary hole on the basis that the original shape structure of the circuit breaker draw bar is not changed and the use characteristics of the circuit breaker draw bar is not affected. In addition, by using the circuit breaker draw bar, the shaft is convenient to disassemble and the whole draw bar does not need to be damaged when the shaft is disassembled, the production cost is favorable to save while the production efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of circuit breaker draw bar.
Background technology
Draw bar is the interior parts that are connected an outbalance of snap close of the connecting rod operating mechanism of circuit breaker, and it all is to adopt axle to be fixed on the mechanism rack together with the snap close combine and assemble usually.In conjunction with the accompanying drawings shown in 1,2, present as can be known circuit breaker draw bar, its draw bar body 1 one ends have axial installing hole 2, and the other end then is solid, mid portion is used to connect snap close, and it is fixing with mechanism rack, draw bar and snap close combination serial connection successively that axle inserts installing hole 2 from an end.In case the parts in the connecting rod operating mechanism go wrong, and then must at first pull down axle, could carry out repair and replacement and adjustment to each parts.
Yet, the shortcoming that existing this class circuit breaker draw bar exists is as follows: owing to have only an end perforate, like this after axle inserts from an end and is connected in series each parts, if problem is want axle is pulled down is very difficult, this be because the axle with draw bar on installing hole 2 are close-fittings, be difficult to axle is extracted from an end, could remove spool so have only draw bar destroyed.And circuit breaker will be through the debugging and the effect of multistep from parts to a finished product switch, so the coherence request to the parts assembling is very strict, parts on the connecting rod operating mechanism particularly, all can involve draw bar as long as occurred problem basically, all draw bar must be destroyed, mechanism could be disassembled, and then the problem parts are keeped in repair, change and adjust, so not only influence production efficiency, and also caused unnecessary waste, increase production cost.
Summary of the invention
The present invention seeks to: a kind of circuit breaker draw bar that axle is disassembled from it of being easy to is provided, and this circuit breaker draw bar applies to can effectively enhance productivity and save production cost in the circuit breaker connecting rod operating mechanism.
Technical scheme of the present invention is: a kind of circuit breaker draw bar, comprise the draw bar body, and described draw bar body one end axially has installing hole, it is characterized in that the other end of described draw bar body axially has the fabrication hole relative with installing hole.
Preferably, the diameter of fabrication hole described in the present invention is less than the diameter of installing hole.With the diameter less than installing hole of the diameter of fabrication hole design, its purpose guarantees that for the assembling degree of depth of Control Shaft axle can not fall to fabrication hole when installing hole inserts, thereby influences the fitted position precision of whole connecting rod operating mechanism.
Preferably, the coaxial heart of fabrication hole described in the present invention and installing hole.
This circuit breaker draw bar provided by the invention is the same with routine techniques when assembling, and axle inserts successively from an end mechanism rack, draw bar and snap close combination serial connection are fixed.In case the connecting rod operating mechanism is in debugging, during verification, when its inner parts go wrong and need tear open spool, can insert from fabrication hole one end with the shaft-like object (for example screw pocket knife, technology axle) of a diameter less than fabrication hole and non-frangibility, axle ejected disassemble, process is extremely succinctly convenient.
Advantage of the present invention is:
1. technical scheme of the present invention is very simple, and it is not changing the original appearance structure of circuit breaker draw bar, and does not influence on the basis of its operating characteristic, by increasing a fabrication hole, has solved the difficult problem of axle dismounting.
2. because this circuit breaker draw bar provided by the invention, conveniently tear axle open, and need not whole draw bar is destroyed during dismounting, so when enhancing productivity greatly, help saving production cost.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is the front view of existing circuit breaker draw bar;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is a front view of the present invention;
Fig. 4 is the left view of Fig. 3.
Wherein: 1, draw bar body; 2, installing hole; 3, fabrication hole.
Embodiment
Embodiment: at first in conjunction with Fig. 1, shown in Figure 2, existing circuit breaker draw bar as can be known, it only has axial installing hole 2 at draw bar body 1 one ends, and the other end then is solid, and mid portion is used to connect snap close.Owing to have only an end perforate, after axle inserts and be connected in series each parts from an end, be very difficult if problem is want axle is pulled down like this, this is because axle is close-fittings with installing hole 2 on the draw bar, be difficult to axle is extracted from an end, could remove spool so have only draw bar destroyed.
In conjunction with Fig. 3, shown in Figure 4 be this circuit breaker draw bar provided by the invention, its draw bar body 1 one ends axially have installing hole 2, mid portion is used to connect snap close, and axially has the fabrication hole 3 relative with installing hole 2 at the other end of draw bar body 1.And the fabrication hole described in the present embodiment 3 and the installing hole 2 coaxial hearts, the diameter of described fabrication hole 3 is less than the diameter of installing hole 2 simultaneously.
This circuit breaker draw bar that present embodiment provides is the same with routine techniques when assembling, and axle inserts successively from installing hole 2 these ends mechanism rack, draw bar and snap close combination serial connection are fixed.In case the connecting rod operating mechanism is in debugging, during verification, when its inner parts go wrong and need tear open spool, can with a diameter less than fabrication hole 3 and not the shaft-like object of frangibility (for example screw pocket knife, technology axle) insert from fabrication hole 3 one ends, axle ejected disassemble, process is extremely succinctly convenient.
Technical scheme of the present invention is very simple, and it is not changing the original appearance structure of circuit breaker draw bar, and does not influence on the basis of its operating characteristic, by increasing a fabrication hole 3, has solved the difficult problem of axle dismounting.
Because this circuit breaker draw bar provided by the invention, conveniently tear axle open, and need not whole draw bar is destroyed during dismounting, so when enhancing productivity greatly, help saving production cost.
Certainly the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All modifications that the spirit of main technical schemes is done according to the present invention all should be encompassed within protection scope of the present invention.
