CN2372527Y - Combined lock for valve - Google Patents

Abstract

The utility model relates to a valve lock, particularly a combined lock for valves, which belongs to the technical field of locks and is composed of a lock body, a seal cap, a lock rod, a lock core and other parts to form a set of special-purpose lockset for a water supply and air supply valve. The combined lock for valves can carry out convenient lock for various pipeline valves which do not need water, gas and heating supply. When the pipeline valves need water supply, or gas supply or heating, the user only needs a key to open and remove the lockset, and then presses an upper rotary hand wheel to recover the use. The lockset can be reused on other pipeline valves which need to be locked.

Description

The combination brake switch and proporting door lock

The utility model relates to a kind of valve, and especially a kind of combined valve lock belongs to lock technology field.

Only a kind of valve on the present Domestic market, in use lack flexibility, must begin in the construction at pipeline, no matter whether user's valve needs to pin, the valve that water supply, air feed or heating unit all will install and fix at user's entrance place, this not only gives and supplies water, the heating unit brings very big inconvenience on key management, and disposable infusion of financial resources is too big, supplies water, the warm unit of worker is difficult to bear.

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, provide a kind of infusion of financial resources less, the door lock of combination brake switch and proporting flexibly easy to use.

For achieving the above object, the technical solution adopted in the utility model is: by the combination brake switch and proporting door lock that lock body, sealing cap and locking bar are formed, the synchronous dead bolt of cross lock core and two ends symmetry is arranged in the lock body, the bottom is provided with the sealing cap positioning hole that matches with the sealing cap upper end; Be provided with the space that the integral body with valve opening and closing bar and lock nut matches in the middle of the sealing cap, be used for closing valve rotating open-close bar and lock nut, two ends, sealing cap bottom are provided with the locking bar stable hole that is connected as a single entity with locking bar; The bottom of locking bar is provided with the curved or chain type various type chain of U-shaped that matches with valve bottom cylindrical body, and two corresponding positions of synchronous dead bolt on two upright end and the lock body respectively are provided with a teeth groove.

Locking bar is striden across the cylindrical body of valve bottom, pass the locking bar stable hole, insert in the lockhole of lock body, and make dead bolt snap in the integral locking state that forms in the teeth groove pipeline valve, this moment is because the lock nut of valve has covered the rotating open-close bar of valve and the lock nut of bottom, make pipeline valve lose the switching function, thereby reach the purpose of cutting off the water, stopping the supple of gas or steam or stopping to heat.

The utility model is compared with the prior art, and is easy to use owing to the structure that has adopted compound mode, good reliability, and disposable less investment, reusable, be the suitable valve of a kind of ideal that solves control water supply, air feed or heating at present.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 8 is a locking state schematic representation of the present utility model.

As Fig. 1, Fig. 2, shown in Figure 3, the combination brake switch and proporting door lock is made up of lock body 1, sealing cap 2 and locking bar 3, adorns cross lock core 7 and two synchronous dead bolts 6 and two lockholes 9 in the lock body 1, and the lower end of lock body 1 is provided with the sealing cap positioning hole 8 that matches with sealing cap 2 upper ends; As Fig. 1, Fig. 4, Fig. 5, shown in Figure 8, the centre of sealing cap 2 is provided with the space that matches with valve opening and closing bar 13 and lock nut 14 integral body, and its upper end is a valve screw rod sealing chamber 7, and its two ends, bottom are provided with the locking bar stable hole 10 that is connected with locking bar; As Fig. 1, Fig. 6, shown in Figure 8, the bottom of locking bar 3 is provided with the curved or chain type various type chain locking bar 12 of U type that matches with valve bottom cylindrical body 15, the outside of U-shaped crook is with locking bar plastic sleeve 4, and two of locking bar 3 upright ends respectively are provided with a teeth groove 5 with dead bolt 6 corresponding positions in the lock body 1.

When needs pin valve, at first shed the hold-doun nut on the valve rotation hand wheel, take down handwheel, sealing cap 2 is enclosed within on valve opening and closing bar 13 and the lock nut 14, again the sealing cap positioning hole 8 on the lock body 1 is buckled in the top of sealing cap 2 and pushes down, then locking bar 3 or chain locking bar 15 are striden across the cylindrical body 15 of valve bottom, pass the locking bar stable hole 10 on the sealing cap, produce excessive degree of vacillating now to the left, now to the right, continue upwards to insert the lockhole 9 in the lock body 1 to prevent locking bar, and dead bolt 6 is snapped in the teeth groove 5 on the locking bar 3, block locking bar and make it and to retreat, thereby make lock body 1 push down the upper end of sealing cap 2, as shown in Figure 8, at this moment, because sealing cap 2 is enclosed within valve rotating open-close bar 13, its underpart has covered the lock nut 14 of valve, and the valve opening and closing structure all is closed in the sealing cap 2, lost the switching function, so far valve has been pinned securely.
