Abstract

The utility model relates to a lock which is a locking device for a machine cabinet. The locking device is designed aiming at defects of different kinds of products. The designed key point is as follows: a connecting plate, a first torsion spring, a second torsion spring, a bolt, a hoisting cable, a first rivet, a second rivet, a baffle plate and a lock plate are arranged between a base plate and a cover board of the locking device for the machine cabinet, and the base plate and the cover board are riveted by the first rivet and the second rivet which have different external diameters. When the hoisting cable is pulled upwards, a connecting piece is driven to move upwards to drive the baffle plate to rotate widdershins so that the baffle plate is separated from the lock plate which rotates widdershins under the actions of the first torsion spring and the second torsion spring, and the locking device for the machine cabinet is in a non-locking state at the time. A fastening buckle pushes the lock plate to rotate deasil, the first torsion spring and the second torsion spring reset automatically, that is, the reset forces of the torsion springs drive the connecting piece and the hoisting cable to reset automatically, and the locking device for the machine cabinet is in the locking state. The locking device has high security performance and fulfills the aim of linkage.

Description

Cabinet Lock Catch Device

Technical field

The utility model relates to lockset, is a kind of Cabinet Lock Catch Device.

Background technology

At present, Chinese patent application number 02266285.5, notice of authorization CN2565765, name is called " parallel interlock lock tooth stepless speed regulation snap close ", it comprises the snap close pedestal, the snap close pull bar, the rotation lock tooth, pedestal rotating shaft and rod shaft are formed, snap close pedestal cross section is " ∏ " shape, the snap close pull bar is that an end is connected with and can allows the tabular entity of the through hole that belt passes, by pedestal rotating shaft and rod shaft two of the pin joints similar leg-of-mutton rotation lock tooth of end face that can rotate around rod shaft side by side, above-mentioned two rotating shafts are located at the two ends on a limit of rotation lock tooth triangle between snap close pedestal and the snap close pull bar.This utility model can be used for belt, also can be used for the locking of other ribbon.

Chinese patent application numbers 200520129234.2, publication number CN2823477, name is called " improvement of the latch part of locomotive anti-theft lock ", it refers in particular to an end side surface of establishing a locking bar and offers a lockhole, and holding the end to be provided with a tapered end, the other end of locking bar then articulates with an end of a catch member, then curved the establishing of the other end of catch member is an arc hook part then, and offer a locating hole in the side of arc hook part, when making the arc hook part of catch member insert in the above-mentioned lockhole, in the time of can being locked by tapered end, its core inserts in locating hole, make the arc hook part can't withdraw from lockhole, and then make catch member be able to the location that locked.Therefore, beat towards the locking bar side, desire to force when separating between catch member and the locking bar, then catch on and stop, cause catch member to be difficult to by breaking away from the locking bar, and then reach more strong thief-proof ability because of arc hook part brute force when stealing person's attempt.

Above-mentioned former structure is slightly complicated, and the latter is used for locomotive anti-theft lock, and both all have certain pinning function; Also exist the deficiency of some aspect.

" Cabinet Lock Catch Device " of the applicant 2007.04.12 application, Chinese patent application numbers 200720108074.2, it is desirable that this structure is in use also owed.

Summary of the invention

For overcoming above-mentioned deficiency, purpose is to provide a kind of structure comparatively simple to this area, pins the higher Cabinet Lock Catch Device of security performance.The purpose of this utility model is to adopt following technical scheme to realize.

A kind of Cabinet Lock Catch Device, this device main points are that junction plate, first torsion spring, bolt, wire rope, first rivet, second rivet, baffle plate, jam plate, second torsion spring are set between base plate and the cover plate, by first rivet and second rivet base plate and cover plate are riveted.Described connector is provided with cross-drilled hole, plane, vertical core, wire rope is that the cross-drilled hole and the connector that pass connector are connected and fixed, one section columniform plane of connector is inserted in the oblong aperture of base plate, this direction of connector is connected with the oblong aperture of base plate is embedded, bolt is inserted in connector, in the hole of an end round corner section inserting bolt of first torsion spring.The pulling of wire rope will drive first, second torsion spring, the interlock of baffle plate, jam plate, clip is stirred also to the orientation of jam plate will drive first, second torsion spring, the interlock of baffle plate, jam plate, and only the two interlock makes the direction of rotation of baffle plate and jam plate different.

Described first rivet, second rivet are provided with different external diameters, and purpose is to realize the following function of setting.

Stage casing external diameter socket first torsion spring of first rivet, its epimere external diameter is inserted in first bottom plate hole, and the end of epimere is encased inside pad and base plate riveted joint, and the hypomere external diameter is inserted in first baffle holes, and the extension of hypomere places first plate hole of cover plate.

Stage casing external diameter socket second torsion spring of second rivet, its epimere external diameter is inserted in second bottom plate hole, and rivet mutually with base plate the end of epimere, and the hypomere external diameter is inserted in the plate hole of jam plate, and the extension of hypomere places second plate hole of cover plate.

Described base plate is provided with first U-lag, and described cover plate is provided with second U-lag, and these two U-lags are corresponding settings.First bottom plate hole of base plate and the corresponding setting of first plate hole of cover plate, second bottom plate hole of base plate and the corresponding setting of second plate hole of cover plate.In the both sides of cover plate long side plate is set, short side plate plays spacing effect.

The periphery of described baffle plate is provided with groove, first boss, and first deep-slotted chip breaker, the periphery of described jam plate is provided with concave surface, second deep-slotted chip breaker, second boss.

Above-mentioned machine components put in place through assembling, and especially offseting of first boss and concave surface stirred, and the cooperating of the corresponding arc of first deep-slotted chip breaker and jam plate, interlocking or separating in time of second deep-slotted chip breaker and clip all will be regulated in assembling.The drawing that wire rope is used external force makes first torsion spring, second torsion spring is stressed or by the guiding dial-out of clip through track, realize that Cabinet Lock Catch Device is in two states, will describe in the specific embodiment.

This Cabinet Lock Catch Device structure is comparatively simple, is easy to produce in batches, and cost is lower; The pinning security performance is higher, easily reaches the purpose of interlocking.
