Abstract
The utility model relates to a dead bolt lock, comprising a bolt box installed on the door and a latch box on the doorframe; wherein the bolt box is provide with a bolt, a tapered end, a drive bar, a handle and a safety button; the cut-in surface of the latch box corresponding to the bolt is a bevel; lower end surface of the bolt is a level; wherein the latch box is provided with a bolt cut-inlet with a width greater than the width of lower end of the bolt. The lower end surface of the bolt has a plurality of alveolus. The lower end surface of the utility model is a level of certain width. Thus even pressed by a hard slice inserted from crack, the bolt will not flex with high safety porperty. Besides, hard slice is easier to be blocked in alveolus positioned on lower end surface of the bolt, the bolt never flex, improving anti-theft effect; the latch box can be provided with a plurality of corresponding bolt cut-inlet in accord with the structure of the bolt. The utility model has the advantage of simple structure, low fabrication cost, easy installation and convenient use.
Description
(1) technical field
The utility model relates to a kind of pin tumbler lock of pick-proof.
(2) background technology
Existing pin tumbler lock is nested and works with being fixed on keeper on the doorframe by the telescopic ramped shaped dead bolt that is installed on the body.Because telescopic dead bolt is ramp type, so, not only can open with key, the thin slice of usefulness hard is oppressed the inclined-plane of dead bolt from crack between a door and its frame in door, also lock can be opened, thereby have potential safety hazard.
(3) summary of the invention
In order to overcome the shortcoming that existing pin tumbler lock is easily opened by hard sheet, no matter providing a kind of, the utility model which kind of thin slice to oppress dead bolt with at the crack between a door and its frame place, all can not make the pin tumbler lock of the safety of lock unlatching.
The technical scheme in the invention for solving the technical problem is:
A kind of pin tumbler lock, include the dead bolt box that is installed on the body, be installed in the keeper on the doorframe, be provided with dead bolt, tapered end, transmission bar, handle, stop button in the described dead bolt box, the approaching side of the corresponding keeper of described dead bolt is an inclined-plane, described dead bolt lower surface is a horizontal plane, described keeper is provided with the dead bolt entry, and the width of described dead bolt entry is greater than the width of described dead bolt lower surface.
The lower surface of described dead bolt is provided with a plurality of teeth groove.
Further, described dead bolt entry structure is: the keeper correspondence position is a ramp structure, and the inclination spacing between keeper upper surface and the lower surface is a dead bolt entry width.
Further, described dead bolt entry structure is: the keeper correspondence position is an engraved structure, and the width of openwork part is a dead bolt entry width.
The beneficial effects of the utility model are: 1, the lower surface of dead bolt is arranged to the horizontal plane of certain width, even if insert hard sheet compressing dead bolt from crack between a door and its frame, dead bolt can not stretch yet, and is safe in utilization; 2, in the dead bolt lower surface teeth groove is set, in case hard sheet inserts crack between a door and its frame, very easily snaps in teeth groove, dead bolt more can not stretch, and has improved anti-theft effect; 3, keeper is according to the structure of dead bolt, can set out multiple corresponding with it dead bolt entry, and is simple in structure, cost of manufacture is low; 4, installation procedure is simple, and is easy to use.
(4) description of drawings
Fig. 1 is a kind of structural representation of the utility model;
Fig. 2 is the another kind of structural representation of the utility model.
(5) specific embodiment
