Abstract
The invention discloses a rotary catch lock comprising a lock cylinder, a lock body and a catch. A dust-proof window is arranged outside a lock hole; the lock cylinder is connected with the catch through a transmission shaft; two sides of the catch are respectively provided with a screw; the transmission shaft is connected with the lock body through the screws and fixing washers; the lock body is fixed on a door through a fixing piece. Because the dust-proof window is arranged outside the lock hole, dust can be effectively prevented from entering the lock body, and the lock body can be protected to some extent.
Description
Technical field
The invention belongs to the lock field, especially relate to a kind of catch lock that is provided with dust-proof window.
Background technology
Lock is a kind of instrument that often uses in the daily life; And according to the difference of actual conditions, the pattern of lock is also different, but traditional lock seldom adopts dust-proof window to lockhole; Make and be locked in the long-term use; Dust or moisture are easy to get into lock core through lockhole, and then the parts in locking are produced corrosion, the precision that influence is unblanked and locked.
Summary of the invention
The technical problem that the present invention will solve provides a kind of simple in structure, can prevent that dust from getting into the rotary catch lock of lock core.
The present invention is realized that by following technical scheme a kind of rotary catch lock comprises lock core, lock body and catch; The lockhole outside is provided with dust-proof window, and said lock core is connected with catch through power transmission shaft, and respectively there is a screw on said catch both sides, and said drive link is connected with lock body through screw, setting-up piece, and said lock body is fixed on the door through fixture.
Beneficial effect of the present invention is: through in the lockhole outside dust-proof window being set, stoped dust or moisture to get into lock core via lockhole, avoided the erosion to the lock body internal part of dust or moisture, improved the precision of unblanking and locking, prolonged the life-span of lock.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein,
1, dust-proof window, 2, lockhole, 3, fixture, 4, setting-up piece, 5, screw, 6, catch.
The specific embodiment
As shown in Figure 1: a kind of rotary catch lock comprises lock core, lock body and catch 6; Lockhole 2 outsides are provided with dust-proof window 1, and said lock core is connected with catch 6 through power transmission shaft, and respectively there is a screw 5 on said catch 6 both sides, and said drive link is connected with lock body through screw 5, setting-up piece 4, and said lock body is fixed on the door through fixture 3.
The course of work of this instance is: the process of unblanking: open dust-proof window 1, key is inserted lockhole 2, screw key drives the inner transfer device of lock body, and then drives drive link revolving force is passed to catch 6, and catch 6 back door that rotates to an angle is opened; The process of locking: key is inserted lockhole 2, and screw key drives the inner transfer device of lock body, and then drives drive link revolving force is passed to catch 6, and intersect with door catch 6 back that rotates to an angle, and lock successfully this moment, covers dust-proof window 1.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
