The specific embodiment
Below in conjunction with specific embodiment the technical scheme among the present invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on embodiments of the invention, those of ordinary skills belong to protection scope of the present invention not making the every other embodiment that obtains under the creative work prerequisite.
The below is described in further detail the embodiment of the invention.
The present embodiment provides a kind of safety anti-theft lock for membrane structure, can be used in the membrane structure locking after the film stretch-draw, and shown in Fig. 1-5, this safety anti-theft lock comprises: plate, latch and tapered end after lock housing, lock housing header board, the lock housing,
Wherein, lock housing 1 is the square structure of inner hollow, one sidewall 101 of lock housing 1 is provided with tapered end load hole 11, the lock housing top board 102 that faces mutually with the upper end of described tapered end load hole 11 place sidewalls 101 is provided with spacing hole 12 (structure of lock housing 1 is referring to Fig. 6), and spacing hole can adopt the strip through hole;
Plate 3 (seeing Fig. 8) after lock housing header board 2 (seeing Fig. 7) and the lock housing is set respectively, the corresponding through hole 21,31 that is provided with installation latch two ends on the plate 3 after lock housing header board 2 and the lock housing on the lock housing 1 at tapered end load hole 11 place sidewalls 101 two ends;
Tapered end 4 structures are seen Figure 10, can adopt the tapered end that is consisted of by lock body 42 and lock bow 41, lock bow 41 can be buckled on the lock body 42 tapered end 4 is in the lock state, the lock bow 41 of tapered end 4 front ends and part are locked body 42 and are arranged in the described lock housing 1 by tapered end load hole 11, the lock bow 41 of tapered end 4 front ends is sleeved between the limited post and stopper pin on the latch 5, the lock bow 41 of tapered end 4 is in the lock state, the stopper pin 52 of latch 5 abuts on the lock body 42 of tapered end 4, the limited post 51 of latch 5 abuts on the lock bow 41 of tapered end 4 and is in spacing hole 12 1 ends on the lock housing 1, thereby make limited post and stopper pin spacing lower of tapered end 4 on lock housing and mortise lock, can't move, and also spacing lower at lock housing and tapered end of latch, can't move, thereby guaranteed that tapered end is fixed in the lock housing, make the lock bow part of tapered end can not prized and damage, improved the safety of lockset.
In the above-mentioned safety anti-theft lock, the locking for ease of the lock bow 41 of tapered end 4 can arrange jacking block 13 by the inwall with respect to tapered end load hole 12 in lock housing 1, and when tapered end 4 pushed in the lock housing 1, lock bow 41 just in time withstood on the jacking block 13, latching operation on the convenience.
In the above-mentioned safety anti-theft lock; the length sum of the radical length of the cylinder of described latch 5 and stopper pin 52 (is seen the mark L among Fig. 9; if be that latch is cylindrical; then be the height sum of diameter and the stopper pin of latch) less than its lock bow 41 interior length (seeing the W that marks among Figure 10) under tapered end 4 unlocking conditions; the length sum of the radical length of the cylinder of latch 5 and stopper pin 52 is greater than length in the lock bow under the tapered end lock-out state; after so both can having guaranteed the tapered end locking; latch is to the position-limiting action of lock body; also can protect under the tapered end unlocking condition, can not affect the transverse shifting of latch in lock bow.
In the above-mentioned safety anti-theft lock, lock body 42 profiles of the shape of the tapered end load hole 12 on the described lock housing, size and tapered end 4, size are complementary, and are encased in the lock housing 1 by tapered end load hole 12 so that the lock bow of tapered end 4 and part are locked body.
The safety anti-theft lock of the embodiment of the invention, by all being arranged on tapered end and latch in the lock housing, the lock housing two ends arrange respectively after lock housing header board and the lock housing in the plate, the lock bow of tapered end is enclosed between the limited post and stopper pin of latch, and when the tapered end lock bow was in the lock state, then tapered end and latch were under the effect of lock housing, play mutually spacing effect, because the lock bow end of tapered end is arranged in the lock housing, can not damaged by sled the good safe antitheft effect of therefore playing.This safety anti-theft lock is simple in structure, easy to use, has antitheft, tamper-resistant function.Use this safety lockset in membrane structure, can be easily to locking after the membrane structure stretch-draw, can make membrane structure under the prerequisite of pneumatic and artificial destruction, guarantee the safety that membrane structure is stressed, the reliable guarantee of the safety that membrane structure integral body is stressed, so that under membrane structure is subjected to pneumatic and artificial destruction, can use safely.
The above; only for the better specific embodiment of the present invention, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
