Abstract
The utility model discloses an anti-theft lock for a rolling gate. The anti-theft lock comprises a lock frame, a cylinder component, a locking bar and a return spring, two ends of the lock frame are provided with guiding blocks extending upwards, the cylinder component is installed on the middle portion of the lock frame, two sides of the cylinder component are respectively provided with a lock bar, one end of the lock bar is connected with a lock bolt of the cylinder component, the other end of the lock bar extends from a passing hole arranged on each guiding block, a spring seat hole is arranged on the lock bar positioned outside each guiding block, a guiding post parallel to the lock bar in the length direction is arranged inside the spring seat hole, the return spring is mounted on the spring guiding post, one end of the return spring abuts on the lateral wall of the spring seat hole, and the other end of the return spring abuts on the lateral surface of each guiding block. Because the return spring is disposed axially on the lock bar and then the lock bar can not generate a component force, the anti-theft lock has the advantages of enlarging horizontal elastic force and increasing lock security on the one hand, on the other hand, realizing closing and opening the rolling gate easily and flexibly because no friction can be produced between the lock bolt and a lock case.
Description
Technical field
The utility model relates to lock, specifically, is a kind of burglary-proofing lock for rolling door.
Background technology
Rolling-gate is widely used in places such as shop, paving, warehouse, is the first safe road guarantee.Because rolling-gate is because the theftproof of lock is not good mostly by prying open, for improving its security personnel's performance, people have done many improvement to rolling gate door lock, on July 19th, 2000 Chinese patent CN2388285, a kind of rolling-gate safety lock is disclosed, form by lock core parts, trace, stop mechanism, guide pad, back-moving spring and swivel hook mechanism, the fixedly connected pin block of carrying that has the inclined-plane in end at the dead bolt of lock core parts door lock, door lock drives the trace action by carrying pin block, has locking groove with the corresponding position of stop mechanism on the trace.Also respectively there is a latch hook both sides at stop mechanism, can in vertical plane, do counterclockwise or the clockwise direction rotation with stretching of trace, hook or throw off the fixedly snap close (this snap close utilizes setscrew and splayed reinforcing bar reinforcement of weld) that is embedded in the concrete surface of rolling-gate below, like this, after opening and mentioning rolling-gate, the end of trace withstands in the gathering sill of rolling-gate both sides doorframe under action of reset spring, trace inserts the lockhole of both sides doorframe automatically when closing rolling-gate under action of reset spring, drive latch hook simultaneously and hook fixedly snap close in the concrete surface, laterally, vertically all locked.Yet, be arranged between guide pad and the trace because back-moving spring is oblique, therefore, will produce component simultaneously at vertical direction and horizontal direction, like this, reduced required horizontal direction elastic force on the one hand, the safety that causes locking reduces; On the other hand, vertical direction elastic force makes the dead bolt of lock core parts and the frictional force between the lock housing increase, and causes opening and closing effort, operates dumb.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of flexible operation, safe burglary-proofing lock for rolling door.
In order to address the above problem, the technical solution of the utility model is: a kind of burglary-proofing lock for rolling door, comprise the lock frame, the lock core assembly, bolt and back-moving spring, the two ends of lock frame are provided with the guide pad that protrudes upward, described lock core assembly is installed at the middle part of this lock frame, respectively be provided with a described bolt in the both sides of this lock core assembly, one end of this bolt is connected with the dead bolt of described lock core assembly, the other end stretches out from the via hole on the described guide pad, on the bolt that is positioned at outside the described guide pad, be provided with spring base hole, in this spring base hole, have one with the parallel lead of described bolt length direction, on this spring lead, described back-moving spring is housed, one end of this back-moving spring is pressed on the sidewall of spring base hole, and the other end is pressed on the side of described guide pad.
One end of above-mentioned spring lead is fixedlyed connected with the sidewall of spring base hole, and the via hole of the other end and described guide pad movingly.
Compared with prior art, the beneficial effects of the utility model are: the utility model will be obliquely installed back-moving spring between guide pad and bolt originally and change into and being axially disposed within on the bolt, bolt just can not produce component like this, has increased horizontal elastic force on the one hand, has increased the safety of lock; Can not produce frictional force between dead bolt and the lock housing on the other hand, easy and flexible all when opening and closing rolling-gate.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is Fig. 1 left view.
The specific embodiment
Further the utility model is illustrated below in conjunction with drawings and Examples.
