Abstract
The utility model discloses a key with double rows of snakelike grooves. The key comprises a key blank. A straight guide groove is formed in one face of the key blank. The snakelike grooves are formed in the other face of the key blank. The groove walls of the snakelike grooves unevenly stretch in the width direction of the key blank to form password teeth. The snakelike grooves comprise the left snakelike groove and the right snakelike groove, and a protruding ridge is formed between the left snakelike groove and the right snakelike groove. A single snakelike groove structure in the traditional technology is abandoned, displacement space of blades is limited, when the numbers of the blades are similar or when a key with the number similar to the numbers of the blades is used, a lock cylinder can not be opened by slowly repeatedly pulling and moving the blades through hand feeling or other means, the phenomenon that a lock is easily opened by a key with similar numbers is avoided, and safety of the key is greatly improved.
Description
Technical field
The utility model relates to key, is the key with Double-row S-shaped groove specifically.
Background technology
Key coordinates lockset to use, and its object is to protect individual privacy or property not to be encroached on.Key has many types at present, now on market, the key of commonplace use is that one side at spoon base mills out a snakelike tank, the concavo-convex password tooth that extends to form of cell wall of snakelike tank, after key is inserted in lock core, password tooth is corresponding one by one with the blade number in lock core, V-type groove all align on blade is arranged on an axis, thereby interior door bolt is dropped in V-type groove, key can be with movable lock core to rotate.But this single snakelike tank structure, because distance between snakelike tank cell wall is larger, make the displacement space of blade larger, particularly close number is easily opened mutually and is opened lock core, cause the safety of this kind of lockset lower, therefore traditional Key structure is need further to improve and promote.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of key with Double-row S-shaped groove, and it has can effectively prevent that adjacent number from opening mutually, the feature such as simple and reasonable.
The utility model solves the technical scheme that its technical problem adopts:
The key with Double-row S-shaped groove, comprise a spoon base, the one side of described spoon base is provided with guiding straight trough, the another side of spoon base is provided with snakelike tank, the cell wall of described snakelike tank is along the concavo-convex password tooth that extends to form of spoon base width, described snakelike tank comprises left snakelike tank and right snakelike tank, between described left and right snakelike tank, is formed with convex ridge.
As the improvement of technique scheme, the two side of described convex ridge respectively with snakelike tank cell wall opposed with it in the concavo-convex extension of spoon base width, left and right snakelike tank groove width separately equates everywhere.
As the further improvement of technique scheme, the notch of described left and right snakelike tank forms respectively two trumpet-shaped targeting ports.
The beneficial effects of the utility model are: the utility model is by arranging left and right two snakelike tanks, abandoned the single snakelike tank structure in conventional art, define the displacement space of blade, make when blade number is close or use the close key of number, cannot slowly overlap examination moving blade and lock core is opened by means such as feels, avoid occurring that close number easily opens phenomenon mutually, improved greatly the safety of key, and the simple and reasonable compactness of the utility model, enforcement is convenient, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another angle schematic diagram of the present utility model;
Fig. 3 is the decomposing schematic representation that the utility model coordinates with lock core.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to Fig. 1 ~ Fig. 3, the key with Double-row S-shaped groove of the present utility model, comprise spoon base 1, the one side of described spoon base 1 is provided with guiding straight trough 11, gib block in the slot of guiding straight trough 11 and lock core 2 is corresponding, being convenient to key looks for position to be inserted in lock core 2 smoothly, the another side of described spoon base 1 is provided with snakelike tank 12, the cell wall of described snakelike 12 grooves is along the concavo-convex password tooth 15 that extends to form of spoon base 1 width, described snakelike tank 12 comprises left snakelike tank 121 and right snakelike tank 122, a described left side, right snakelike tank 121, between 122, be formed with convex ridge 13, after described key is inserted in lock core 2, convex clip 211 on blade 21 snaps onto a left side, right snakelike tank 121, in 122, the utility model has been abandoned the single snakelike tank structure in conventional art, define the displacement space of blade 21, define blade 21 in the removable amount of spoon base width, make when blade number is close or use the close key of number, cannot slowly overlap examination moving blade and lock core is opened by means such as feels, avoid occurring that close number easily opens phenomenon mutually, improved greatly the safety of key, and the simple and reasonable compactness of the utility model, it is convenient to implement, cost is low.
In the present embodiment, the two side of preferred described convex ridge 13 respectively with the cell wall of snakelike tank 12 opposed with it in the concavo-convex extension of spoon base width, left and right snakelike tank 121,122 groove width separately equates everywhere, this structure can further limit card 21 in the removable amount of spoon base width, better avoids occurring that close number easily opens phenomenon mutually.
In the present embodiment, the notch of described left and right snakelike tank 121,122 forms respectively two trumpet-shaped targeting ports 14, and when the setting of targeting port 14 is convenient to insert key, the convex clip 211 on blade 21 imports in left and right snakelike tank 121,122.
The above, be better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
