Abstract

The utility model relates to a locking device of a pin type lock. The utility model can lock a rotating valve, and can also lock a plane device. The utility model is composed of a lock core sleeve, a lock core and a rotating lock stopper, wherein, the outer end of the lock core is provided with a pin shaft hole, and one end of the pin shaft hole is an open type. The rotating lock stopper is radially provided with a groove, and is rotated. A lock shaft and a rotating pin stopper are fixed together by a pin. The utility model has the advantages of simple structure and easy realization, and is especially suitable for a valve with a big opening diameter of unit heating.

Description

Pin formula lock locking closure

The utility model relates to lock technology field, and exactly it is a kind of pin formula lock locking closure.

At present, the valve that industries such as chemical industry, hot-water heating are used can be opened or close mostly with general utility tools such as hand or spanners, should not carry out management.And in unified heating system, with the family is that the unit heating is a developing direction, and after promptly the user paid heating cost, the professional workforce can realize heating with the valve open that common conduit is led to this user, but anyone all can arbitrarily open existing valve, can't realize management.

The purpose of this utility model provides a kind of pin formula lock locking closure, and it makes common people be difficult to open the opening and closing of lock, must use private key, and can use in valve and plane device, thereby the unlatching of control valve effectively realizes the purpose of managing.

The purpose of this utility model is achieved by the following scheme, it is made up of lock core cover, lock core and rotation backset, it is characterized in that: lock core cover (6) outer end has the open pin shaft hole of an end (10), rotate backset (7) and radially have groove (11), rotating backset (7) can rotate, and lock shaft (3) is fixed together with pin (4) with rotation backset (7).

The utility model has the advantages that: simple in structure, realize can controlling the unlatching of large bore valves effectively, and can using in the control of plane of motion device easily, for being that the unit heating provides assurance with the family, and have anti-theft effect preferably.

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

Fig. 1 is a structural representation of the present utility model.

Left view when Fig. 2 removes lock and lock body for Fig. 1.

1 is that lock, 2 is that lock body, 3 is that lock shaft, 4 is that pin, 5 is that bearing pin, 6 is that lock core cover, 7 is that rotation backset, 8 is that key, 9 is that lock core, 10 is that pin shaft hole, 11 is a groove among the figure.

Embodiment 1:

The utility model is relatively simple for structure, and general Lock Factory all can produce.Key can be selected antitheft door cruciate flower Key structure for use, can be applicable to radially or plane structure.When lock is valve seat, lock body is a spool, this moment can be with the utility model from radially packing into, can be on valve seat and the lock tube pin shaft hole corresponding position bearing pin of packing into, rotate backset when lock is locked and blocked by bearing pin, lock core cover and lock core all can not take out, and have entered in the spool owing to rotate the backset front end, lock core can not rotate, and has reached the purpose of pinning valve.

Embodiment 2:

Present embodiment structure and embodiment 1 are identical, just when diameter valve is big, can eccentric be contained in the Vertical direction of spool, and using method is with embodiment 1.

Embodiment 3:

Present embodiment structure and embodiment 1 are identical, and just lock and lock body are the structure of plane combination, and the utility model vertically is contained in the lock body, rotate backset and pack in the lock, can realize pinning the device of plane structure.

Claims

1, pin formula lock locking closure, it is made up of lock core cover, lock core and rotation backset, it is characterized in that: lock core cover (6) outer end has the open pin shaft hole of an end (10), rotate backset (7) and radially have groove (11), rotating backset (7) can rotate, and lock shaft (3) is fixed together with pin (4) with rotation backset (7).
