Technical Field

The utility model relates to an anti-unlocking lock belongs to tool to lock technical field.

Background

The existing valves such as lock valves and the like which can be opened and closed are generally operated by padlocks, switches or secret locks which are opened and closed by utilizing internal magnets, the unlocking modes of the existing valves are easy to be mastered by related people, the anti-theft performance is not enough, no trace can be left after the existing valves are opened by theft, and the existing valves are inconvenient for evidence collection and supervision.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a prevent unblanking, can only carry out the destructiveness after the closure and unblank, its theftproof performance is good, easily supervises.

Prevent the open lock include: a lock shaft; the annular lock groove is arranged at one end of the lock shaft; the stop head is fixed at the other end of the lock shaft; and a locking mechanism locked with the annular locking groove.

When the valve core switch of the valve is arranged in the valve opening pipe, the locking shaft is arranged above the valve core switch of the valve and penetrates through the valve opening pipe, and the distance between the stop head and the locking mechanism is matched with the pipe diameter of the valve opening pipe.

The locking mechanism comprises a lock cap, and a first accommodating cavity, a second accommodating cavity and a third accommodating cavity are sequentially arranged on one side of the lock cap; the sleeve is connected with the first accommodating cavity through external threads; and a collar engaged with the annular locking groove; the rand sets up in the second holds the intracavity, the third holds the chamber and suits with lock shaft tip size.

During installation, the clamping ring can be placed in the second accommodating cavity, an open slot can be formed in one end of the sleeve, and the sleeve is screwed into the first accommodating cavity through a special tool.

Preferably, the gasket is arranged in the first accommodating cavity.

Preferably, the outer side of the stop is arc-shaped.

The retaining head is not convenient to be fixed, and the phenomenon that the locking shaft is pulled through the fixed retaining head to damage the clamping ring and the clamping of the annular locking groove can be effectively avoided.

Preferably, the end of the lock shaft is arc-shaped.

The clamping ring is convenient to be sleeved and clamped in the process of inserting the lock shaft into the locking mechanism.

Preferably, the locking cap is in a shape of a circular truncated cone.

The locking cap is not convenient to be fixed, and the locking shaft can be effectively prevented from being pulled through fixing the locking cap to damage the clamping ring and the clamping of the annular locking groove.

Preferably, the other side of the third accommodating cavity penetrates through the lock cap.

The use principle and the process are as follows: the locking mechanism is assembled in the early stage, specifically, the clamping ring is placed in the second containing cavity, the sleeve is screwed into the first containing cavity through a special tool, a gasket is sleeved on the lock shaft during use, then the lock shaft penetrates through the valve opening pipe above the valve core switch, finally the lock shaft end is locked with the locking mechanism, and specifically, when the end part of the lock shaft sequentially penetrates through the sleeve, the gasket and the clamping ring and enters the third containing cavity, the annular locking groove on the lock shaft is locked with the clamping ring. When a worker needs to open and close the valve, the stop head on the lock shaft is damaged, and the valve can be normally opened and closed by taking down the lock shaft; when the valve is locked again, a new locking shaft is taken to be locked with the locking mechanism, so that the reuse cost is reduced.

The utility model has the advantages that: the anti-unlocking structure is simple, the installation is convenient, the lock can be unlocked only destructively after being locked, and the anti-theft performance of the valve is greatly improved.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Example 1

As shown in fig. 1-5, the anti-unlocking lock of the present invention comprises a lock shaft 1; an annular lock groove 2 arranged at one end of the lock shaft 1; a stopper 3 fixed at the other end of the lock shaft 1; and a locking mechanism locked with the annular locking groove 2. The locking mechanism comprises a locking cap 4, and a first accommodating cavity 5, a second accommodating cavity 6 and a third accommodating cavity 7 are sequentially arranged on one side of the locking cap; the sleeve 8 is connected with the first accommodating cavity 5 through external threads; and a retainer ring 9 engaged with the annular lock groove 2; the clamping ring 9 is arranged in the second accommodating cavity 6, and the third accommodating cavity 7 is adaptive to the size of the end part of the lock shaft. And a gasket 10 disposed in the first receiving chamber 5. The outer side of the stop head 3 is arc-shaped. The end part of the lock shaft 1 is arc-shaped. The lock cap 4 is in a circular truncated cone shape.

In this embodiment, the valve opening pipe 13 is a circular pipe, the corresponding stopper 3 and the corresponding washer 11 are adapted to the outer wall radian of the valve opening pipe 13, the locking cap 4 is adapted to the outer wall radian of the valve opening pipe 13, the locking shaft 1 is arranged above the valve core switch 12 of the valve and penetrates through the valve opening pipe 13, and the distance between the stopper 3 and the locking mechanism is adapted to the pipe diameter of the valve opening pipe 13.
