CN2046909U - Cylinder lock with two pin valve - Google Patents

Abstract

The utility model discloses a cylinder double-pin valve lock, relating to the study to the cylinder structural valve lock. On the basis of the lock body of an existing valve lock and the lock control structure, the lower end of a lock core of the cylinder double-pin valve lock is provided with two convex axles which correspond with each other; a clutch composed of a clutch sleeve, a double pin, and a pin spring is designed. When the cylinder double-pin valve lock is used, the fixed position do not need to be rotated and selected after a key is inserted; the use and operation is convenient thereby, besides, with the double pin being taken as a clutch executive piece, the large radial torsion can be born; so the service life of the cylinder double-pin valve lock is improved thereby.

Description

Cylinder lock with two pin valve

The utility model belongs to the lock class.

At present, mainly contain two about the open report to valve lock research: the disclosed application number of first utility model patent communique is: 86207564 " the lock control arrangement of clutch of valve " are when this device uses in reality, after need pressing on-of pin with hand, can key lock, obviously operation is real is inconvenience; It two also is disclosed 827,129 99 " Clutch locks " of utility model patent communique.This is locked in must be by key rotation lock core to a permanent position in the use, the opening and closing of ability control lock; The lock of this structure also will be processed with screw thread on lock core in addition, and then very inconvenient to making it limited by the permanent position, and its processing is manufactured also complicated.Moreover: on the structure of above-mentioned two kinds of products, it is stressed bigger all to exist on-of pin, just produces flexural deformation to the problem that lockset was lost efficacy.

And the improvement that the utility model carries out at the existing problem of the valve lock of said structure just design.A kind of novel valve lock is provided, makes it when reality is used, after key inserts, need not rotate and select the permanent position, obviously made things convenient for and used operation; In addition the utility model with two latchings as the clutch executive item, this pair latching can bear bigger radially torsion, there is not the stressed flexural deformation of pin and makes the lockset failure phenomenon, improved the practicality of product, and then make problem obtain solution, realized the design's purpose.

The valve lock that the utility model provides is a billiards structure, it is on structure design, based on the lock body and the lock control structure of existing valve lock, different one be the structure of having improved former lock core, the 2nd, designed one and half from the work clutches.That is: this pellet shot from a slingshot double-pin valve lock kept existing valve lock by handle (4), the lock body that lock housing (14) connects firmly by steady pin (11) reaches by lock core (6), bottom billiards (9), last pellet shot from a slingshot (10), marble spring (3) is decided core spring (5), is decided the lock control structure that core pellet shot from a slingshot (8) is formed.Its improved technical essential is the lock core in the lock control structure (6) structure is improved, and improvement place is for being provided with two corresponding mutually protruding axles in lock core (6) lower end; Newly designed in addition by clutch cover (1), twin columns pin (12).And the semi-automatic clutch of pin spring (17) composition.Twin columns pin (12) in this clutch is to be integrally combined by a pin spring (17) by two single pins centres to form, the contraction of its pin is controlled by key and the lock core that has protruding axle, and stretching out of twin columns pin is after key inserts, and finishes automatically under spring action.

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is an overall structure schematic diagram of the present utility model:

Fig. 2 is the front view of lock core (6) structure;

Fig. 3 is the vertical view of lock core (6) structure:

Fig. 4 is the front view of single latch structure;

Fig. 5 is single latch structure vertical view.

With reference to accompanying drawing 1: steady pin (11) is fixed on lock housing (10) to handle (4) and goes up the two and constitute lock body, decide core pellet shot from a slingshot (8) and decide core spring (5) with lock core (6) movingly in lock housing, bottom billiards (9), last pellet shot from a slingshot (10) and marble spring (3) are arranged in respectively on the lock core (6), constitute a lock control structure.The lower end of lock core (6) processes two protruding axle (19) (20), and its two protruding axle can become 30 ° of degree angles with the core groove.Each protruding axle drives a pin respectively, adorns a pin spring (17) in the boring in the middle of two pins.Two pins are combined into a pair of pin.Plug (16) with clutch cover (1) pin extremely valve (15) on, be contained in lock housing (14) lower end, fixed cover (18) blocks clutch cover (1), and is dead with pin (13) pin below.Behind two protruding (19), (20) of key (7) and lock core (6), 75 ° of degree of drive twin columns pins (12) rotation, the twin columns pin is withdrawn in to the lining hole from two of clutch cover (1), extract key (7), last pellet shot from a slingshot (10) enters under the promotion of marble spring (3) in the lock core lock core (6), rotate handle (4) this moment and can not drive clutch cover (1) and valve handle (15), valve handle (15) is at locked state.Behind key (7) insertion lock core, it is protruding under the effect of pin spring (17) to rotate handle (4) twin columns pin, and can insert automatically clutch cover (I) to the lining hole in, rotate handle (14) this moment, clutch cover (1) and valve lock (15) rotate thereupon, and valve is in opening to (15).

The utility model structure improvement is made simply, and is easy to use, practical, can be widely used in rotary torsion less than on all Valve with lock of 200 kilograms.

Claims (1)

1. pellet shot from a slingshot double-pin valve lock, it includes handle (4), lock housing (14) by the fixing lock body of forming of steady pin (11), by lock core (6), bottom billiards (9), following pellet shot from a slingshot (10), marble spring (3) is decided core pellet shot from a slingshot (8), decides the lock control structure that core spring (5) is formed; It is characterized in that:

The lower end of the lock core (6) in a. described lock control structure is provided with two protruding axle (19) (20),

B. it also is provided with by clutch cover (1), twin columns pin (12), the semi-automatic clutch that pin spring (17) is formed, wherein twin columns pin (12) is to be combined as a whole by a pin spring (17) in the middle of the two single pins.
