Description

A kind of improved board-like lock

The utility model relates to lockset, or rather, relates to a kind of improved board-like lock.

Conventional lock comprises padlock and bicycle lock etc., and its locking bar is a cylindricality, and is fluted on it, and after locking bar inserted lock body, dead bolt was stuck in groove, and locking bar can not be deviate from lock body, finishes lock function.This class lock survivability is not strong, and the one, the cylindricality locking bar subjects to " locking pliers " and destroys, even the overstriking locking bar of φ 10 also can be cut off by " locking pliers "; The 2nd, dead bolt blocks the strength deficiency of the groove of locking bar, prizes with crowbar, or pounds with sledgehammer, all is easy to and will destroys herein.At the problems referred to above, novel board-like lock (patent No. 95106774.5 and 95214324.0) has had significant improvement in safety.It adopts cross section is the plate shape locking bar of narrow and long rectangular, the shear failure that can resist " locking pliers " effectively; Dead bolt hole on the plate shape locking bar is a through hole, enters that the cylindricality dead bolt runs through this hole locking behind the lock body, makes crowbar and sledgehammer all be difficult to it is damaged.In addition, the dead bolt hole on this plate shape locking bar has several that are in diverse location, can be according to the latched position that need adjust different locking bar length, with locked object body " holding tightly " relatively, thereby more be difficult to destroy.Yet this new technology also has its weak point: at first, have on the lock body two narrow and long rectangular shape of cross sections with plate shape locking bar identical run through latch arm hole, this four jiaos is that right angle and not only narrow but also dark rectangular opening are difficult to processing; Secondly, this is designed to the double lock tongue locking, and the dead bolt hole position symmetry on the locking bar biside plate is consistent, must separate certain distance again between the dead bolt hole, so use the gear of hour locking lever adjustable-length position insufficient; Once more, the end cross-sectional of this plate shape locking bar is onesize narrow and long rectangular also, is difficult for inserting the latch arm hole of lock body during use; In addition, this lock body and locking bar are the metal manufacturing, easily wear-out failure are caused in the locked object surface.

Task of the present utility model is to provide a kind of handling ease, and is easy to use, has the improved board-like lock of very strong ability of resisting destruction again.

This task is finished in the following way: the cross section of (1), plate shape locking bar changes the narrow and long rectangular of long and narrow chains round or four jiaos of chamferings or circular arc into, makes that the latch arm hole that runs through of same shape is easy to processing on the lock body; (2), adopt Single spring holt lock fixed, staggering mutually in the dead bolt hole position of locking bar biside plate, uses hour locking lever adjustable length position to double approximately; (3), with plate shape locking bar end chamfering or circular arc, make it be easy to insert latch arm hole on the lock body; (4), add one section plastics or rubber sleeve, on lock body, add plastics or rubber support, to prevent the locked object surface of wearing and tearing at the round part of plate shape locking bar; (5), the pellet shot from a slingshot hole of lock core placed locking bar inserts a side on the lock body, just can't destroy pellet shot from a slingshot after the pinning, thus safer.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the profile schematic diagram of lock body and plate shape locking bar.

Fig. 2 is the schematic diagram of three kinds of shape of cross sections of plate shape locking bar.

Fig. 3 is the generalized section of lock body.

Fig. 4 is the schematic diagram that lock body adds plastics or rubber support.

Fig. 5 is the schematic diagram that plate shape locking bar adds plastics or rubber sleeve.

11 is lock body among the figure, and 12 is latch arm hole, and 13 is the pellet shot from a slingshot hole, and 14 is spring, and 15 is dead bolt, and 16 is lock core, and 17 is plastics or rubber support, and 21 is plate shape locking bar, and 22 is dead bolt hole, and 23 is plastics or rubber sleeve.

Fig. 1 is a profile of the present utility model.Have identical with the plate shape locking bar 21 shape of cross sections latch arm hole 12 that runs through on the lock body 11; Have the dead bolt hole 22 that runs through on the plate shape locking bar 21, and 22 positions of the dead bolt hole on the biside plate face stagger mutually, locking bar 21 end chamfering or circular arcs make it be easy to insert latch arm hole 12 on the lock body 11; The orientation in the pellet shot from a slingshot hole 13 on the lock body (the fixing and firm lock core of card is used) is taken at locking bar and inserts a side, and this hole is sheltered from by locking bar and locked object after the locking, so can't destroy.

Fig. 2 is three kinds of difformities of plate shape locking bar cross section, the long and narrow chains round of the first, and promptly circular arc is processed on narrow and long rectangular two narrow limits, and another is a narrow and long rectangular, four jiaos of chamferings, also having a kind of is that narrow and long rectangular is processed little circular arc for four jiaos.These several processing all are easy to for plate shape locking bar, and the latch arm hole 12 identical with these several shape of cross sections also relatively easily processed on the lock body 11 simultaneously.

Fig. 3 is the generalized section of lock body.Cylindricality dead bolt 15 cross sectional shapes are identical with dead bolt hole 22 shapes on the plate shape locking bar 21, and dead bolt 15 is supported by spring 14, and stretched out or withdrawn by lock core 16 (concrete structure is omitted) control.After plate shape locking bar 21 inserted latch arm hole 12, the dead bolt of being controlled by lock core 16 15 stretched out the different dead bolt holes that insert the locking bar side plate, and several different latched positions can be arranged; Jam plate inserts latch arm hole again behind axial Rotate 180 degree, the dead bolt hole of another side plate of plate shape locking bar 21 is locked by dead bolt, and several different latched positions are arranged again in addition.With double lock tongue locking phase ratio, Single spring holt lock is about one times of different latched position how surely, and as long as dead bolt material and sectional dimension are suitable, have enough intensity opposings and destroy.This user of being improved to brings bigger convenience and more safe and reliable.

Fig. 4 and Fig. 5 are equipped with plastics or rubber support 17 and plastics or rubber sleeve 23 respectively on lock body 11 and locking bar 21, like this, with the locked object body " hold tightly " locking after, can not cause wearing and tearing to its surface.

Compare with the design of former plate-shape lock, it is easier to the utlity model has processing, use more convenient, And more safe and reliable characteristics. It not only can lock bicycle, motorcycle, door, case and bag etc., And can be used for the lock automobile after adding some auxiliary accessories.

Each part of the utility model all adopts the metal manufacturing.
