CN2377311Y - Runner type synchronous three-way theftproof lock - Google Patents

Abstract

The utility model discloses a slide groove type synchronous three-way theft proof lock. A connecting rod is added on a lock bolt of an ordinary theft proof and a slide groove is added on a lock shell. An upper and a lower slide plates which are symmetrical are arranged in the slide groove, and inclined grooves on the two slide plates are penetrated and connected by the connecting rod of the lock bolt. When a key hole is twisted by a key and the lock bolt is laterally moved, the upper and the lower slide plates are respectively moved upwards and downwards simultaneously, and thus the goal of three-way door locking can be achieved and the defect of one-way door locking of an ordinary lock is overcome. The problems of easy failure happening and high cost of a three-way lock with a spring structure can be solved.

Description

The synchronous three-dimensional theftproof lock of chute-type

The utility model belongs to the synchronous three-dimensional lock of innovation, particularly chute-type chute-type synchronous up and down, that locking bolt is stretched, contracted to three directions of side of anti-money door latch structure.

The inside of the three-dimensional theftproof lock of Xiao Shouing is spring structure in the market, breaks down the cost height easily.

The purpose of this utility model is the problem at above-mentioned existence, adopts the chute-type structure to replace spring structure, not only simplifies production technology, reduces product cost, the more important thing is that to make theftproof lock safe and reliable, reduces fault.

The purpose of this utility model is achieved in that

Appropriate location on the locking bolt of the transversal stretching of common theftproof lock inside increases a locking bolt connecting rod, and locking bolt connecting rod and locking bolt synchronous horizontal in the reversing of key moves.In the lock housing outer side edges chute is installed, two upper slide and lower skateboards to lining are arranged in the middle of the chute.Upper slide and lower skateboard respectively have an oblique chute and two straight runners, on, the straight runner of lower skateboard is overlapping, locate by the straight runner pilot pin, tiltedly chute is worn by the locking bolt connecting rod and is connected, in the time of need locking a door key being inserted keyhole reverses, locking bolt and locking bolt connecting rod move synchronously laterally, the locking bolt connecting rod promotes oblique chute, upper slide is moved up, and lower skateboard moves down, and the upper end of upper slide is fixed a connecting rod and locked lever linkage, the bottom of lower skateboard, fix a connecting rod and following locking bar interlock, on, following locking bar makes progress synchronously, move down, reach the purpose that the synchronous three-dimensional of chute-type is locked a door.

Owing to adopt the utility model, increase promotes upper and lower slide plate simultaneously on the locking bolt that laterally moves of common theftproof lock, reaches the purpose that three directions are locked a door synchronously.

Fig. 1 is the utility model structural representation, and Fig. 2 is the upper slide structural representation, and Fig. 3 is the lower skateboard structural representation.

In conjunction with the accompanying drawings and embodiments, further describe structure of the present utility model.

Outer side edges [9] in common antitheft lock housing [13] goes up installation chute [14], in the chute [14] lining is installed slide plate [2] and lower skateboard [5], and a connecting rod [11] is fixed in the upper end of upper slide [2], the connecting rod [11] and the lever linkage of locking; A connecting rod [12] is fixed in the lower end of lower skateboard [5], connecting rod [12] and following locking bar interlock.The straight runner [3] of upper slide [2] is overlapping with the straight runner [3] of lower skateboard [5], by reference column [10] location, guarantees that straight runner [3] can only move up and down, can not move left and right.The locking bolt connecting rod [8] that the skewed slot [4] of upper slide [2] and lower skateboard [5] is fixed on locking bolt [6] simultaneously passes.Key is inserted keyhole [7] to be reversed, when locking bolt [6] laterally moves laterally, locking bolt connecting rod [8] also laterally moves, the skewed slot [4] that promotes upper slide [2] and lower skateboard [5] moves to oblique respectively, upper slide [2] is moved up, and the connecting rod [11] of upper slide [2] upwards promotes to go up locking bar and moves; Locking bar moved under the connecting rod [12] of lower skateboard [5] promoted downwards, finished horizontal stroke, upper and lower task of locking a door simultaneously.When opening the door,, finish the task that lock leaves door lock simultaneously as long as a key reverses round about.

Claims (1)

1, the synchronous three-dimensional theftproof lock of chute-type, form by antitheft lock housing, locking bolt, it is characterized in that, outer side edges [9] in above-mentioned antitheft lock housing [13] goes up installation chute [14], in the chute [14] lining is installed slide plate [2] and lower skateboard [5], a connecting rod [11] is fixed in the upper end of upper slide [2], the connecting rod [11] and the lever linkage of locking; A connecting rod [12] is fixed in the lower end of lower skateboard [5], connecting rod [12] and following locking bar interlock, the straight runner [3] of upper slide [2] is overlapping with the straight runner [3] of lower skateboard [5], locate by reference column [10], guarantee that straight runner [3] can only move up and down, can not move left and right, the appropriate location in above-mentioned locking bolt [6], fix a locking bolt connecting rod [8], the locking bolt connecting rod [8] that the skewed slot [4] of upper slide [2] and lower skateboard [5] is fixed on locking bolt [6] simultaneously passes.
