Description

Elastic reset lock

Technical Field

The utility model relates to the technical field of valves, specifically an elasticity lock that resets.

Background

Valves are plumbing accessories used to open and close a pipe, control flow direction, regulate and control parameters of the transport medium (temperature, pressure and flow). According to their function, they can be classified into shut-off valves, check valves, regulating valves, and the like.

The current manual valve can not be reset when in operation, which affects the actual use effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an elasticity lock that resets to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a spring return lock comprising:

the bracket is arranged on the manual ball valve;

the connecting shaft is connected with a valve rod of the manual ball valve;

the handle is rotatably arranged on the bracket, and one end of the handle is matched with the connecting shaft;

and the elastic resetting piece is arranged on the handle and used for driving the handle to reset.

As a further technical scheme of the utility model, elasticity resets and includes:

a pull rod mounted within the handle;

the reset spring is sleeved outside the pull rod, and when the handle rotates, the reset spring stretches.

As a further technical scheme of the utility model, fixed mounting has the limiting plate that is used for restricting handle pivoted on the support.

As a further technical scheme of the utility model, the turned angle of handle is no more than 90.

Compared with the prior art, the beneficial effects of the utility model are that: the rotating handle and the reset spring are stretched, the driving handle returns to the original state under the action of the pull rod, the rotating angle of the handle is 90 degrees under the action of the limiting plate, the handle is connected with the connecting shaft, the connecting shaft is connected with the valve rod of the valve, the rotating handle drives the connecting shaft to drive the valve rod of the valve to rotate so as to open or close the valve, and the automatic reset device is mainly used for rotating 90-degree valves such as ball valves, butterfly valves and the like.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The embodiment of the utility model provides a so realize, as the elasticity that fig. 1, fig. 2 show locks that resets, include:

the bracket 2 is arranged on the manual ball valve 3;

the connecting shaft 1 is connected with a valve rod 5 of the manual ball valve 3;

the handle 6 is rotatably arranged on the bracket 2, and one end of the handle 6 is matched with the connecting shaft 1;

and the elastic resetting piece is arranged on the handle 6 and used for driving the handle 6 to reset.

When the utility model is used in practice, the handle 6 is connected with the connecting shaft 1, the connecting shaft 1 is connected with the valve rod 5 of the manual ball valve 3, the rotating handle 6 drives the connecting shaft 1 to drive the valve rod 5 of the manual ball valve 3 to rotate, and the valve is opened or closed; when the handle 6 is rotated, the elastic reset piece is stressed, and when the external force is removed, the elastic reset piece drives the handle 6 to return to the original state.

As shown in fig. 2, as a preferred embodiment of the present invention, the elastic restoring member includes:

a pull rod 8 mounted within the handle 6;

and the return spring 7 is sleeved outside the pull rod 8, and when the handle 6 rotates, the return spring 7 stretches.

In one aspect of this embodiment, when rotating the handle 6, the return spring 7 is stretched, and under the effect of the pull rod 8, the driving handle 6 returns to the original state, preferably, the fixed mounting has the limiting plate 4 for limiting the rotation of the handle 6 on the support 2, specifically, the handle 6 has a rotation angle of 90 ° under the effect of the limiting plate 4, thereby being better applied to the automatic reset of the valve rotating 90 ° such as a ball valve, a butterfly valve, etc.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
