Abstract
The utility model provides a prevent to break off with fingers and thumb mortise lock courage disconnected and that take out, includes a rectangular shape lock core shell, two plungers form lock core, locates two shift fork and clutch assembly between the lock core, and the shift fork of saying has about 30 perhaps bigger angle of deflections under blocking state, and its crucial part lies in: handing -over department at lock core and shift fork respectively is equipped with an annular wild card slot and puts into circlip on every lock core, simultaneously the shift fork suitably the department be equipped with corresponding annular alan faneca slot, use making two assembled lock cores, can fuse with the shift fork lock joint through circlip, and then guarantee the shift fork that deflects in advance, in any case can both firmly block in the lock body.
Description
Technical field
The technology of the present invention belongs to mechanical lock field, especially relates to the lock pin lock gall on security door.
Background technology
The existing lock pin lock gall be contained on security door, wherein most form of structure all roughly as shown in Figure 1, be not difficult to find out, middle screw 11 place is a fatal weak link, be easy to be broken by force to turn round by force break and be separated with lock body, then Special Tool can just be inserted door-lock opening, for this reason, industry proposes the multiple lock pin lock gall that prevents by the design scheme interrupted, add Baogang's skin or embedded steel disc such as to lock gall shell, or be carry out splicing lock core housing etc. with steel bar, but limit by bulk, its actual effect is difficult people's will to the greatest extent still.
Summary of the invention
For this reason, the present invention proposes a kind of design scheme of uniqueness, make the lock pin lock gall applying this technology, broken even unfortunate, also still cannot take out, thus reached the generation effectively stoping pirate of the open behavior.
The present invention is realized by the technical scheme of the following stated: a kind of preventing breaks lock pin lock gall that is disconnected and that take out, comprise a strip lock core shell with at least two sections of pipe cavitys, said two sections of pipe cavity places on an axis, wherein distinguish each sheathed piston-shaped lock core, shift fork and clutch component is provided with between these two lock cores, said shift fork is relative to the ymmetry center plane of said strip lock core shell, there is about 30 ° or larger deflection angle in the lockout condition, its crucial part is: in the junction of lock core and shift fork, each lock core be respectively provided with an annular exterior bayonet slot and insert circlip, be provided with corresponding annular inner card cage at the suitable place of shift fork simultaneously, use two lock cores making to assemble, can be connected with the inner card cage snapping of shift fork by circlip.
On the shift fork of above-mentioned lock pin lock gall, at the circumference of each annular inner card cage, be laid with 3 or 4 radial direction through hole, so that when needs dismounting lock core, the obstruction of back-up ring can be removed by insertion tool.
A kind of preventing breaks lock pin lock gall that is disconnected and that take out as above, because two lock cores are wherein and said shift fork snapping and be linked to be one, the anti-damage performance significantly improving whole lock gall on the one hand, and be owing to having preset deflection angle on the other hand, said shift fork can be blocked in mortise lock body, thus, even this lock pin lock gall is unfortunately broken disconnected, also still cannot take out from lock body, thus further increase by the difficulty of pirate of the open.
Accompanying drawing explanation
Fig. 1 is the structural perspective of lock pin lock gall of the present invention.
Fig. 2 is that the local of lock pin lock gall of the present invention is disassembled and partial schematic sectional view.
Detailed description of the invention
Elaborate below in conjunction with the embodiment of accompanying drawing to lock pin lock gall of the present invention.
As depicted in figs. 1 and 2, lock pin lock gall of the present invention comprises the lock core shell 1 of a strip, this lock core shell is provided with the pipe cavity running through two, and this pipe cavity is in centre, and suitable place is divided into two sections by grooving, one piston-shaped lock core 2 is respectively set in each section of pipe cavity, between these two lock cores, is provided with shift fork 3, and is located at the clutch component 4 in shift fork, suitable place below shift fork, said lock core shell is provided with installation screw 11.Be not difficult to find out, this installation screw whereabouts is a fatal weak link, be easy to be twisted off or produce serious flexural deformation by force, in order to avoid the generation of this situation, improve the anti-damage performance of lock pin lock gall, the present invention, to the assembling mode between lock core and shift fork, has made improvement drastically.
Be exactly specifically: in existing lock pin lock gall, its lock core is all directly be fixed on lock core shell, its shift fork is then the end being socketed in two lock cores by the cavity being located at two ends, if the weak part in the middle part of lock core shell is broken, two lock core is also separated with shift fork at once.And in lock pin lock gall of the present invention, lock core holds the annular exterior bayonet slot 21 of back-up ring 5, by between shift fork and lock core shell, move on in the cavity of shift fork, meanwhile, be also provided with annular inner card cage 31 at the correspondence position of said cavity, so, assemble between later lock core and shift fork, be just linked to be one by back-up ring snapping, thus drastically increased the integrated explosion proof system performance of lock pin lock gall.
In order to improve lock pin lock gall of the present invention further, the deflection angle of about 30 ° also preset by said shift fork, that is, when this lock pin lock gall is in locking states, between the ymmetry center plane of shift fork and the ymmetry center plane of lock core shell, there is the angle of about about 30 °, or also can deflect a larger angle, for example 45 ° or 60 ° etc., its effect will allow shift fork can block in lock body exactly, when there is no key rotation lock core, just this lock pin lock gall can not be disassembled from the lock body door.
In order to further improve lock pin lock gall of the present invention, particularly consider the needs being convenient to dismantle lock core, suitable place on its shift fork, namely at the circumference of each said annular inner card cage, also uniformly be provided with several radial direction through hole 32, so that insertion tool extrudes the back-up ring in draw-in groove, until back-up ring departs from draw-in groove, and said number of openings is often to enclose 3 to 4 as well.
Claims (2)
1. one kind prevents from breaking lock pin lock gall that is disconnected and that take out, comprise a strip lock core shell with at least two sections of pipe cavitys, said two sections of pipe cavity places on an axis, wherein distinguish each sheathed piston-shaped lock core, shift fork and clutch component is provided with between these two lock cores, said shift fork is relative to the ymmetry center plane of said strip lock core shell, there is about 30 ° or larger deflection angle in the lockout condition, it is characterized in that: in the junction of lock core and shift fork, each lock core be respectively provided with an annular exterior bayonet slot and insert circlip, be provided with corresponding annular inner card cage at the suitable place of shift fork simultaneously, use two lock cores making to assemble, can be connected with the inner card cage snapping of shift fork by circlip.
2. lock pin lock gall according to claim 1, is characterized in that: on described shift fork, at the circumference of each annular inner card cage, is laid with 3 or 4 radial direction through hole, so that when needs dismounting lock core, can remove the obstruction of back-up ring by insertion tool.
