CN2315277Y - Compact anti-theft lock - Google Patents

Abstract

The lock and the lock catch form a fastening device, and the lock body can be axially and movably matched, so that the anti-theft lock has the advantages of compact structure, pick-proof, shear-proof and beating-proof performance, convenience in operation, strong universality and the like.

Description

The tight type theftproof lock

The utility model relates to the lock of special construction, the lock that particularly a kind of lock core can separate with lock body.

Lockset for the single side open and close door wing, padlock is modal a kind of, its use, locking are all very convenient, but also make padlock have obvious defects thus: because padlock is buckled on the crossette of a wing or doorframe, lockset exposes fully, spaces many, that exert oneself, space are also big, thus its pick-proof, anti-cut, the anti-poor performance of beating.

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of tight type theftproof lock simple, convenient, the structure close and firm of manipulating is provided.

The purpose of this utility model is achieved by the following technical solution: the tight type theftproof lock, the snap close that includes lock body, tapered end, is loaded on lock core in the tapered end, is fastened with tapered end etc., special feature is that lock body is discrete two parts, correspondence is fixed on a wing and the doorframe respectively, and tapered end and snap close also are loaded in the discrete lock body respectively; Form a fastening device between tapered end and the snap close, and tapered end can axially movablely cooperate with lock body.

Such structure, after Men Yiyu doorframe closure, two discrete lock bodies closely side by side, tapered end inserts in the snap close, and tapered end, snap close, locking bolt are enclosed in the lock body compactly, each component space is little, thereby pick-proof, anti-ly cut, the anti-performance of beating is good; Meanwhile, when opening the door wing, need only use key operated lock core, tapered end is taken out in the lock body fully get final product, easy to operate, highly versatile.

Below in conjunction with drawings and Examples the utility model is further elaborated.

Fig. 1 is the structural representation of the utility model when sealed;

Fig. 2 is the lateral view of Fig. 1;

Fig. 3 is the utility model assembling schematic diagram.

Referring to Fig. 1, Fig. 2 and Fig. 3, the lock body of present embodiment is divided into left lock body 3 and right lock body 6 two parts (also can be upper and lower two parts), solid welding or be anchored on a wing and the doorframe respectively, all coaxial installing hole that has of two parts lock body is respectively in order to install tapered end 2 and snap close 7.Tapered end 2 is the multidiameter structure, and butt end is loaded in the right lock body 6, and the knob end has shoulder hole then to overhanging in the tapered end 2, and lock core 8 and locking bolt 5 are housed respectively in it, and lock core 8 axially links with locking bolt 5.Locking bolt 5 stretches out in outside the tapered end 2 to snap close 7 directions, and locking bolt 5 terminations also are fixed with perpendicular bolt 4; Snap close 7 is fixed in the left lock body 3, is milled with the clevis 1 and the step trough that are fastened with the rotation of locking bolt 5 ends on the snap close 7, forms fastening device.

Referring to Fig. 1, in the time will opening wing, key inserts the lock core 8 in the right lock body 6, and half-twist, lock core 8 drives locking bolts 5 and perpendicular bolt 4 around the axis half-twist, thereby makes the breach of the perpendicular just corresponding clevis 1 of bolt 4, remove the padlock state, then lock core 8 is extracted out in right lock body 6, in snap close 7, extracted out, Men Yi can be opened together with locking bolt 5, perpendicular bolt 4; Otherwise, when wanting the latching door wing, earlier Men Yi is closed, the right lock body 6 that makes hollow and the left lock body of button 7 with lock 3 are corresponding to be penetrated right lock body 6 straight cuttings with tapered end 2 together with perpendicular bolt 4, locking bolt 5 then and goes in the snap close 7 of left lock body 3 side by side, makes the breach of the clevis 1 that perpendicular bolt 4 can just pass through enter clevis 1, key again, drive locking bolt 5, perpendicular bolt 4 half-twists by lock core 8, the perpendicular bolt 4 and the breach of clevis 1 are staggered, form the snapping blocking.

In sum, the utility model has obvious advantage:

1, compact conformation opens and closes simple to operate;

2, whole lock connects closely, and the member gap is little, and is solid and reliable;

3, crashproof, pick-proof, the anti-performance of cutting are good;

4, the tapered end highly versatile is easy to use.

Claims (2)

1, tight type theftproof lock, the snap closes that include lock body, tapered end, are loaded on lock core in the tapered end, are fastened with tapered end etc. is characterized in that:

Lock body is discrete two parts, and correspondence is fixed on a wing and the doorframe respectively, and tapered end and snap close also are loaded in the discrete lock body respectively; Form a fastening device between tapered end and the snap close, and tapered end can axially movablely cooperate with lock body.

2, theftproof lock according to claim 1 is characterized in that being projected with locking bolt to the snap close direction on the tapered end, and the locking bolt termination is fixed with perpendicular bolt, and the lock core shaft in locking bolt and the tapered end is to interlock; Then have the clevis that is fastened with the rotation of locking bolt end on the snap close, form fastening device.
