Abstract
The invention discloses a rotary connecting rod lock, which comprises a locking core, a transmission rod and a lock frame; two transmission rods are provided; circular grooves are arranged at two ends of the transmission rod; the lock core is pin-connected in the central position of the housing; circular bumps matched with the circular grooves on the transmission rod are arranged at two sides of the lock core; a limiting rod is arranged on the lateral surface of the lock core; and a circular bump connected with the transmission rod is arranged in the corresponding position of the lock frame. By setting the limiting rod on the lock core, the accuracy of lock is improved. Meanwhile, by using the lock frame, the connecting frame can do directly up and down vertical movement. Consequently, the accuracy of lock is improved.
Description
Technical field
The invention belongs to the locking device field of locking door, especially relate to a kind of rotary connection lock that is applied on cabinet used in everyday, the door.
Background technology
Link lock is a kind of mechanical lock that often uses in daily life or the industry; Traditional link lock mainly by swiveling wheel, lock core,, spring leaf, connecting rod and a plurality of drive disk assembly form; Drive each drive disk assembly through lock core, realize its function thereby drive disk assembly drives connecting rod again.But find that in long-term practice the degree of accuracy of lock is not high, i.e. link lock descending and be difficult to up and down accurately put in place; Simultaneously because traditional link lock drive disk assembly is many, internal structure is complicated, so send after the fault not easy-maintaining.
Summary of the invention
The technical problem that the present invention will solve provides a kind of degree of accuracy height, simple in structure, rotation link lock of being convenient to keep in repair of locking.
The present invention is realized that by following technical scheme a kind of rotary link lock comprises lock core, drive link and lock frame; Said drive link has two, and the drive link two ends are provided with circular groove; Said lock core pin is connected to the shell center, and said lock core both sides are provided with the round boss that is complementary with the drive link upper groove, and said lock core side is provided with gag lever post, and the relevant position is provided with the round boss that is connected with drive link on the said lock frame.
Further, said shell is a hollow-core construction, and the shell center is provided with hole and the boss that is complementary with lock core.
Further, said lock frame is connected with connector, and said connector is an open column shape, and the connector sidewall is provided with through hole.
Further, said lock core is connected with handgrip.
Beneficial effect of the present invention is: one, through adopting the lock frame, realized the vertical motion straight up and down of connecting rod, and improved the degree of accuracy of lock; Two, through gag lever post is set on the lock core, make under the connecting rod stop to continue behind this position descending, the degree of accuracy that has also improved lock; Three, give the lock frame through drive link with the power transmission of lock core, because the lock frame is fixedly connected with connecting rod, so lock is simple in structure, the fault that has reduced lock takes place.

The specific embodiment
As shown in Figure 1: a kind of rotary link lock comprises lock core 4, drive link 3 and lock frame 1; Said drive link 3 has two, and drive link 3 two ends are provided with circular groove; Said lock core 4 is pinned at the shell center, and said lock core 4 both sides are provided with the round boss that is complementary with drive link 3 upper grooves, and said lock core 4 sides are provided with gag lever post, and the relevant position is provided with the round boss that is connected with drive link 3 on the said lock frame 1; Said shell 7 is a hollow-core construction, and shell 7 centers are provided with hole and the boss that is complementary with lock core 4; Said lock frame 1 is connected with connector 2, and said connector 2 is an open column shape, and connector 2 sidewalls are provided with through hole; Said lock core 1 is connected with handgrip 5.
The course of work of this instance is: connecting rod is connected with connector 2 through bar hole 6, and when locking, handgrip 5 turns clockwise; Lock core 4 promotes lock frame 1 outside vertical motion through drive link 3 and gag lever post, owing to lock frame 1 is connected with connector 2, so connector 2 moves with it under the drive of lock frame 1 in the same way; Connector 2 and then promotion connecting rod outwards move; When gag lever post moves to certain position, will be blocked by lock frame 1, this moment, the other end of connecting rod accurately got into lockhole, thereby realized locking function; When unblanking, the handgrip 5 that turns clockwise, lock core 4 is through drive link 3 dilatory lock frame 1 inside vertical motions; Because lock frame 1 is connected with connector 2; So connector 2 moves with it under the drive of lock frame 1 in the same way, connector 2 and then dilatory connecting rod inwardly move, and when gag lever post moves to certain position, will be blocked by shell 7; This moment, the other end of connecting rod accurately broke away from lockhole, thereby realized unlocking function.
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.
