Description
Technical field
The utility model relates to automobile lock core field, especially relates to a kind of automobile automotive lock locking plate anti-drop structure.
Background technology
At automobile manufacturing field, anti-theft device is very important system, GB-15740 has enforceable requirement to alarms and security systems for automobiles, and the complete vehicle lock core (containing ignition lock, car door lock etc.) with locking plate is the important component part of alarms and security systems for automobiles.
Each lock core generally has 7 ~ 8 locking plates, locking plate coordinates with key and controls lock core mechanism locking, the key combination that often group cylinder lock locking system uses all is greater than 1000 kinds, so locking plate assembling is very complicated time-consuming work, locking plate adopts artificial or automatic mechanism assembling, locking plate after installing very easily comes off, loses in operation circulation handling process, and causing does over again reprocesses or reprocess to make mistakes and cause locking plate not mate with key, therefore needs the structure designing a kind of locking plate slip-off preventing to address this problem.
Utility model content
The purpose of this utility model is to provide a kind of automotive lock locking plate anti-drop structure, solves existing automobile locking plate easy loss that drops in lock core in the process of carrying, reprocesses inconvenient problem.
The utility model solves the technical scheme that its technical problem adopts: a kind of automotive lock locking plate anti-drop structure, comprise lock core, locking plate, in locking plate plug-in mounting and lock core, the sidewall of lock core offers the notch for locking plate turnover, one of them lateral wall of described locking plate is provided with outwardly step surface, described lock core inside wall is provided with boss, between step surface and boss, is provided with recoil press spring; The position limiting structure of restriction locking plate landing is provided with between described lock core and locking plate.
Further, described locking plate is provided with projection relatively and on the outer wall of step surface opposite side, described lock core inwall to be provided with projection suitable first and to step down groove, and described first the step down stroke of the length of groove and locking plate is suitable.
Alternatively, described locking plate is provided with groove of stepping down relatively with on the outer wall of step surface opposite side, described lock core inwall is provided with first projection suitable with groove of stepping down, described in the step down stroke of the length of groove and locking plate suitable.
Preferably, described projection and locking plate integrated punching shaping.
The beneficial effects of the utility model: by arranging the projection of cooperation and groove of stepping down on lock core and locking plate, namely ensure that locking plate has certain active strokes in lock core, can ensure that again locking plate can not drop with the overlap joint of groove of stepping down because of protruding in the notch of lock core, prevent from losing in the process of carrying.Described projection and locking plate integrated punching shaping, structure is simple, and easy to process, cost is low.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the first sectional view of stepping down groove fit on locking plate projection and lock core in the utility model.
Fig. 2 be in the utility model on lock core first protruding with locking plate on to step down the sectional view of groove fit.
Detailed description of the invention
Embodiment 1:
A kind of automotive lock locking plate anti-drop structure, as shown in Figure 1, comprise lock core 1, locking plate 2, in locking plate 2 plug-in mounting and lock core 1, the sidewall of lock core 1 offers the notch 3 passed in and out for locking plate 2, described one of them lateral wall of locking plate 2 is provided with outwardly step surface 21, described lock core 1 inside wall is provided with boss 11, between step surface 21 and boss 11, is provided with recoil press spring 10.Described locking plate 2 is provided with protruding 4 relatively and on the outer wall of step surface 21 opposite side, and protruding 4 is shaping with locking plate 2 integrated punching.Described lock core 1 inwall is provided with groove 6 of stepping down with protruding 4 suitable first, described first the step down length of groove 6 is suitable with the movement travel of locking plate 2 in lock core, ensures the normal moving range of locking plate 2, plays the function of unblanking with locking.
During assembling, make locking plate be fit in lock core by certain extruding force, after having assembled, projection is stuck in first and steps down in groove, and locking plate can not be dropped out easily, and needing to apply certain power could extract locking plate from lock core.
Embodiment 2:
A kind of automotive lock locking plate anti-drop structure, as shown in Figure 2, comprise lock core 1, locking plate 2, in locking plate 2 plug-in mounting and lock core 1, the sidewall of lock core 1 offers the notch 3 passed in and out for locking plate 2, described one of them lateral wall of locking plate 2 is provided with outwardly step surface 21, described lock core 1 inside wall is provided with boss 11, between step surface 21 and boss 11, is provided with recoil press spring 10.Described locking plate 2 is provided with groove 5 of stepping down relatively and on the outer wall of step surface 21 opposite side, and described lock core 1 inwall is provided with first projection 7 suitable with groove 5 of stepping down, described first projection 7 and the machine-shaping of lock core 1 one.Length and the movement travel of locking plate 2 in lock core of described groove 5 of stepping down are suitable, ensure the normal moving range of locking plate 2, play the function of unblanking with locking.
During assembling, make locking plate be fit in lock core by certain extruding force, after having assembled, the first projection is stuck in steps down in groove, and locking plate can not be dropped out easily, and needing to apply certain power could extract locking plate from lock core.
