Abstract
A lock tumbler sheet for preventing keyhole from blocking is provided with a raised slanting sheet in the middle of one end of the prior lock tumbler sheet. When the lock tumbler sheet is mounted on the lock, the end of the raised slanting sheet is outside the opening of back end of the key hole, thereby avoiding blocking the back end of the key hole. Even if the sundries block the key hole, the front end of the key hole is poked by the key, thereby squeezing the sundries from the back end of the key hole by the slanting sheet and avoiding trouble of unlocking after the key hole is blocked. The utility model is of a simple structure and convenient to be used for users.
Description
Technical field
The utility model relates to lock, especially a kind of tapered end rotatable lamella of preventing key hole plug.
Background technology
The tapered end rotatable lamella is mounted on the tapered end, and its effect is the rotation by it, and the latch fitting that drives in the lock body moves, and moving back and forth of latch fitting can reach opening or closing of lock.When existing tapered end rotatable lamella is installed on the tapered end, basically the rear end of the keyhole in the tapered end is blocked, if foreign material are arranged this moment to be filled in the keyhole in the tapered end, foreign material are gone out except the preceding end hook from key, can not disclose from the rear end of keyhole, and will the foreign material hook be gone out quite difficulty from the front end of keyhole.If the foreign material hook is not gone out, key does not advance keyhole, and lock does not just leave.
Summary of the invention
The purpose of this utility model just provides a kind of tapered end rotatable lamella of preventing key hole plug simple in structure.
The tapered end rotatable lamella of preventing key hole plug is in the design of the middle part of existing tapered end rotatable lamella one end an oblique sheet of having lifted up to be arranged, its oblique sheet end of having lifted up is outside the port of keyhole rear end, do not block the rear end of keyhole, even foreign material are arranged like this blocks keyhole, as long as disclose into from the keyhole front end with key at the front end of keyhole, foreign material just are extruded by oblique sheet from the rear end of keyhole easily, after foreign material are removed, key can stretch into and put in place, and lock also just can have been opened.
The tapered end rotatable lamella of this preventing key hole plug is compared with existing tapered end rotatable lamella, has the following advantages:
1, because the rear end of keyhole is not plugged, helps foreign material are removed, can solve the problem that is difficult to unblank after the common obstruction that exists of present various security door lockset;
2, simple in structure, cost does not increase, and has but increased a kind of anti-clogging function, helps being user-friendly to.
Description of drawings
Fig. 1 is the structural representation that the tapered end rotatable lamella that foreign material fill in is arranged;
Fig. 2 is the structural representation of the utility model tapered end rotatable lamella;
Fig. 3 be among Fig. 2 A to diagrammatic sketch.
The specific embodiment
The tapered end rotatable lamella of preventing key hole plug is in the design of the middle part of tapered end rotatable lamella 2 one ends an oblique sheet 5 of having lifted up to be arranged, and when tapered end rotatable lamella 2 was installed on the tapered end 1, the rear end of keyhole 3 was not blocked in its oblique sheet 5 ends of having lifted up outside keyhole 3 rear end ports.Even foreign material 4 are blocked keyhole 3, as long as disclose into key at the front end of keyhole 3, foreign material 4 just can be extruded by oblique sheet 5 from the rear end of keyhole 3.The problem that has been difficult to unblank after having avoided keyhole to stop up.
Claims (2)
