Abstract
The utility model discloses a kind of internal tooth key structure, comprise key (1), locking plate (2), lock core (3), locking plate spring (4), lock body (5), it is characterized in that: it is novel every position tooth (6) that key (1) is provided with the profile of tooth coordinated with locking plate (2), the novel tooth position every position tooth (6) is increased to eight, be divided into upper and lower both sides, tooth position, 4, every limit, and the tooth position on every limit is all that spaced teeth position is connected, the crest of each tooth position and trough are the transition of varied angle line; Key (1) is provided with the I-groove A(7 coordinated with locking plate (2), lock core (3)); Locking plate (2) is provided with the I-groove B(8 coordinated with key (1)); Lock core (3) is provided with the concave groove (9) coordinated with key (1).Compared with the existing technology, tartar number of combinations increases the utility model, and mutual opening rate reduces, and pick-proof, theftproof improve; Contact engaging and separating force reduces, and uses feel very smooth and easy.
Description
Technical field
The utility model belongs to key technical field, relates to a kind of internal tooth key structure particularly.
Background technology
Automobile key is in use most important to the safe antitheft of automobile, therefore to the structure of key and quality requirements higher.In prior art, there is following problem in key: key tooth flower number of combinations is few, and mutual opening rate is high, and theftproof reduces; Key contact engaging and separating force is large, and the use feel of plug key has some setbacks; Can put in lockhole with the stripe object outside non-key, open lock, pick-proof, theftproof reduce, and therefore product exists potential safety hazard, and result of use is bad.
Summary of the invention
It is many that the purpose of this utility model is to provide a kind of tartar number of combinations, and mutual opening rate is low, and pick-proof and anti-theft is high; Contact engaging and separating force is low, uses feel internal tooth key structure smoothly, to overcome the deficiencies in the prior art.
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: a kind of internal tooth key structure, comprise key, locking plate, lock core, locking plate spring, lock body, it is characterized in that: it is novel every position tooth for being provided with the profile of tooth coordinated with locking plate on the key, the novel tooth position every position tooth is increased to eight, be divided into upper and lower both sides, tooth position, 4, every limit, and the tooth position on every limit is all that spaced teeth position is connected, the crest of each tooth position and trough are the transition of varied angle line; Be provided with the I-groove A coordinated with locking plate, lock core on the key; Locking plate is provided with the I-groove B coordinated with key; Lock core is provided with the concave groove coordinated with key.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the profile of tooth coordinated with locking plate on the key of the present utility model is novel every position tooth, and key tooth flower number of combinations increases, and mutual opening rate reduces, and theftproof improves greatly; Key contact engaging and separating force reduces, and the use feel of plug key is very smooth and easy.Owing to being provided with the I-groove coordinated with locking plate, lock core on the key, locking plate is provided with the I-groove coordinated with key, lock core is provided with the concave groove coordinated with key, and cannot put in lockhole with any stripe object outside non-key and open lock, pick-proof and anti-theft improves greatly.Therefore the utility model compared with the existing technology, and tartar number of combinations increases, and mutual opening rate reduces, and pick-proof, theftproof improve; Contact engaging and separating force reduces, and uses feel very smooth and easy.

Fig. 2 is the partial enlarged drawing of Fig. 1,
Fig. 3 is the structural representation of key of the present utility model;
Fig. 4 is the structural representation of locking plate of the present utility model;
Fig. 5 is the structural representation of lock core of the present utility model;
Fig. 6 is the novel structural representation every position tooth of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to according to a kind of internal tooth key structure detailed description of the invention, feature and the effect thereof that the utility model proposes, be described in detail as follows.
See Fig. 1-6, a kind of internal tooth key structure, comprise key 1, locking plate 2, lock core 3, locking plate spring 4, lock body 5, it is characterized in that: it is novel every position tooth 6 that key 1 is provided with the profile of tooth coordinated with locking plate 2, the novel tooth position every position tooth 6 is increased to eight, is divided into upper and lower both sides, tooth position, 4, every limit, and the tooth position on every limit is all that spaced teeth position is connected, the crest of each tooth position and trough are the transition of varied angle line; Key 1 is provided with the I-groove A7 coordinated with locking plate 2, lock core 3; Locking plate 2 is provided with the I-groove B8 coordinated with key 1; Lock core 3 is provided with the concave groove 9 coordinated with key 1.
The profile of tooth coordinated with locking plate on the key of the present utility model is novel every position tooth, and key tooth flower number of combinations increases, and mutual opening rate reduces, and theftproof improves greatly; Key contact engaging and separating force reduces, and the use feel of plug key is very smooth and easy.Owing to being provided with the I-groove coordinated with locking plate, lock core on the key, locking plate is provided with the I-groove coordinated with key, lock core is provided with the concave groove coordinated with key, and cannot put in lockhole with any stripe object outside non-key and open lock, pick-proof and anti-theft improves greatly.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, anyly do not depart from the technical solution of the utility model content, the any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
