Publication number is that the model utility of 204025871U discloses a kind of valve handle, the joint of handle is with sleeve joint hole, the front end of joint is stitched with the adjustment communicated with sleeve joint hole, the fork arm of seam both sides is regulated to adopt bolt arrangement to be interconnected, the front end of described locking plate is bent with location piece downwards, the angle that the position stop piece fiting constraint handle on location piece and valve rotates.Bolt arrangement adjustment is adopted to regulate the width of seam in the valve handle that the utility model provides, and then the width of sleeve joint hole is changed, thus the elasticity of adjustable valve rod in sleeve joint hole, make it more reasonable with coordinating of valve rod, and valve handle carries location piece to limit the angle of handle unlatching, avoid and rely on the location piece arranged separately to carry out locking handle, thus saved cost.But this model utility does not do detailed restriction for fixing positioning hole, cause locating effect in using process and bad, and handle is long easily causes misoperation.
Model utility content
Problem to be solved in the utility model is to provide a kind of high security valve handle, increases the safety in utilization of valve, the probability that minimizing accident occurs.
A kind of high security valve handle, comprise valve body and handle, described handle comprises underpart and upper end portion, described underpart is connected by brace with described upper end portion, described underpart is connected with described valve body, described brace is arranged the locked collar and two hole clippings, described locked collar lower end arranges protruding fixture block, on described valve body, corresponding described protruding fixture block arranges draw-in groove, on the described locked collar, corresponding described hole clipping arranges fixed hole, below described upper end portion, rotating shaft is set, described rotating shaft is arranged L shape fixture, described L shape fixture comprises fixed end and handle end, the corresponding described hole clipping of described fixed end arranges two bayonet locks, described fixed end is connected with described upper end portion by locking spring.
Further, described upper end portion comprises front-end and back-end, and described front end is connected by bending axle with described rear end.
Further, above the described locked collar, pushing block is set.
Further, described handle end adopts flexible rod, and described handle end arranges Anti-slip cover.
The utility model provides a kind of high security valve handle, comprise valve body and handle, described handle comprises underpart and upper end portion, described underpart is connected by brace with described upper end portion, described underpart is connected with described valve body, described brace is arranged the locked collar and two hole clippings, described locked collar lower end arranges protruding fixture block, on described valve body, corresponding described protruding fixture block arranges draw-in groove, on the described locked collar, corresponding described hole clipping arranges fixed hole, below described upper end portion, rotating shaft is set, described rotating shaft is arranged L shape fixture, described L shape fixture comprises fixed end and handle end, the corresponding described hole clipping of described fixed end arranges two bayonet locks, described fixed end is connected with described upper end portion by locking spring.The utility model relies on protruding fixture block to stretch in draw-in groove to realize fixing, lockable handle be in order to realize valve handle open or off state time by locked or avoid the generation of misoperation, traditional is just fixed for the handle under off state, also need during rotatable handle to carry out hand steered to the locked collar, operation bothers very much, the application adopts two hole clippings, the hole clipping of bottom and bayonet lock carry out being fixed handle when being engaged in valve closing, when valve turned on by needs, bayonet lock is extracted out, the locked collar moves obliquely, when the fixed hole on the locked collar corresponding with the hole clipping on brace top neat after use bayonet lock to fix, no longer need manpower to remove the fixing locked collar like this when rotatable handle, prevent its downward landing from affecting the normal rotation of handle.Bayonet lock is arranged on L shape fixture, and when bayonet lock is extracted out by needs, the bayonet lock of fixed end just can be extracted out by user's rotating handles end from hole clipping, facilitates the movement of the locked collar, operates very simple.
Described upper end portion comprises front-end and back-end, and described front end is connected by bending axle with described rear end.The upper end part of handle is two parts, adopts bending axle to connect, is convenient to the bending of upper end portion, namely shortens the outreach of handle, can greatly reduce valve and turn on the rear probability by mistake touched, improve the Security of valve.
Above the described locked collar, pushing block is set, the convenient movement to the locked collar.
Described handle end adopts flexible rod, described handle end arranging Anti-slip cover, when not using handle end, the length of handle end can be shortened, and avoids that handle end is long to be impacted in Production Regional.
The beneficial effects of the utility model: the utility model can improve on original Handle base, can carry out locked to handle when valve turns off, the operation of handle is not affected when handle rotates, the less probability by mistake touching handle of energy after valve opening, considerably increase the safety in utilization of valve, decrease the probability had an accident, facilitate the operation of workman.
