Description

Antitheft multiple rows of tooth-engraved key

Technical field

It the utility model is related to a kind of lock system, more particularly to a kind of antitheft multiple rows of tooth-engraved key.Belong to daily hardware Product technical field.

Background technology

At present, the mechanical lock of hardware lockset market sale, antitheft principle is generally all upper and lower pinball structure, by two sections of bullets Son composition, one section is the detent ball for blocking lock core, and one section is the different number pellet of length, when key inserts lock gall, key The depth of upper tartar coordinates with the length of number hoodle, the contact surface of upper and lower two hoodles is on the circumference of lock gall, you can Lock gall is rotated to unlock.And the important parameter for weighing lockset theftproof performance is the different tooth numbers of key, the number of different tooth numbers It is to be arranged in a combination by hoodle number and hoodle level difference, hoodle quantity is geometric progression relation from different tooth numbers, so will The amount of different tooth numbers is set to increase the quantity that must just increase hoodle, mechanical lock in the market is due to by technology and lockset The limitation of structure can not possibly design many marble holes on single, tartar arrangement at most also with regard to three row's tartars, this lockset due to Tartar columns is few, and the quantity of hoodle is corresponding also just few, causes that the secret key amount of lockset is small, mutual opening rate is high, and theftproof performance is also just poor. The center line of other existing lockset hoodle hole is all machined to vertical, hoodle hole so between row and row with key surface Can be arranged in parallel so that key by simple processing with regard to reproducible, exist easily opened by technology, instrument unlatching, skeleton key etc. Mode is opened.

Utility model content

Technical problem to be solved in the utility model is for above-mentioned prior art deficiency, there is provided a kind of antitheft multiple rows of tooth Flower key, improves the theftproof performance of lockset, satisfies social needs.

The technical scheme in the invention for solving the above technical problem is：A kind of antitheft multiple rows of tooth-engraved key, including key Spoon body, the cross sectional shape of the key body are the flat key of rectangle, are symmetrically offered on four faces of key body Tartar, because the same center of circle is pointed at all hoodle centers, so an inclined angle be present with key surface in key tooth flower, Corner angle tartar is milled with four corner angle of key body, tartar alternates arrangement on two row's corner angle, in the key body Head is provided with crescent structure, it is ensured that the pellet in the same center of circle is will focus on during key insertion lock core along crescent moon towards surrounding Diffusion pushes back marble hole.

Preferably, the tartar insertion groove milling on key surface, teeth form shape is hidden.

Compared with prior art, the utility model has the advantage of：

1st, the key cross sectional shape that the system uses is the flat key of rectangle, and flat key has four faces and four ribs Angle, the milling tartar on corner angle, has more two row tartars now（Tartar on another two corner angle is because the positive and negative use of key is so be pair Claim）, each column tartar has multiple hoodle positions.Which adds the combination of substantial amounts of key, improve system security and Anti-theft.

2nd, the center line of all marble holes of the system points to the same center of circle, so marble hole exists necessarily with key surface Angle of inclination, cooperating therewith tartar on the key also should mutually have an angle with key surface, when duplication of going beyond one's commission key with The angle of inclination of this lockset design is slightly different, and for mutually level hoodle in the tartar of different angle, hoodle just can fall tooth Flower bottom, pellet will be higher by lock core periphery, prevent it from opening lockset.The key of this design is that angle of inclination is difficult to survey Amount, the tartar of key is replicated from going beyond one's commission, play good anti-theft effect.

3rd, the system key employs crescent structure, and feature is center when key insertion lock gall initially touches hoodle A point, then as the insertion of key, the directive hoodle of institute can spread along crescent moon towards surrounding, ensure key insertion When will can often arrange hoodle and push back hoodle hole, key is smoothly entered lock core.

4th, in the groove milling of tartar position, it is therefore an objective to disturb the tartar of bad attempt to identify, prevent duplication of going beyond one's commission.Groove is with tartar The depth is risen and fallen and has flute profile different in size, and flute profile amount of variability is very big, and it can be had influence on to tartar depth, marble hole away from, pellet The judgement at hole angle of inclination, form more efficient anti-copying means.

Embodiment

The utility model is described in further detail with reference to embodiments.

As shown in Fig. 1-4, a kind of antitheft multiple rows of tooth-engraved key, including key body 1, the key the utility model is related to The cross sectional shape of spoon body 1 is the flat key of rectangle, and flat key has four faces and four corner angle, the two of key body 1 Tartar 1.1 is symmetrically offered in plane, the tartar points to the same center of circle so certain angle all be present, in key due to hoodle hole Corner angle tartar 1.2 is milled with the corner angle of body 1, has more two row tartars, each column tartar has multiple hoodle positions and two groups of corner angle teeth 1.2 are spent to alternate arrangement, above design just prevents tartar from going beyond one's commission to replicate and add substantial amounts of key tooth flower combination, improved The security and anti-theft of system, used because key is tow sides, tartar along rectangle diagonal be it is symmetrical, this There have been 10 row's tartars on key body 1 for sample.

Lock body part corresponding with the key, the center line of all marble holes points to the same center of circle, so marble hole and key There is certain angle of inclination in spoon plane, cooperating therewith tartar on the key also should mutually have an angle with key surface, when Go beyond one's commission duplication key and angle of inclination that this lockset designs it is slightly different, tartar of the mutually level hoodle in different angle Interior, hoodle just can fall tartar bottom, and pellet will be higher by lock core periphery, prevent it from opening lockset.The pass of this design Key is that angle of inclination is difficult measurement, the tartar of key is replicated from going beyond one's commission, plays good anti-theft effect.

Because all hoodle holes all point to the same center of circle so that pellet all leans in the presence of pellet spring to circle center Hold together, space is not left in lock core, therefore the key in the utility model employs crescent structure, i.e., described key body 1 Head be crescent structure 1.3, be a point at center when key initially touches hoodle, then as key insert Entering, the directive hoodle of institute can spread along crescent moon towards surrounding, and hoodle will can often be arranged during key insertion by, which ensureing, pushes back hoodle hole, Key is set smoothly to enter lock core.

Tartar 1.1 in described 1 liang of plane of key body penetrates groove milling, it is therefore an objective to disturbs the tartar of bad attempt to know Not, assignment of going beyond one's commission is prevented, as the tartar depth rises and falls and has flute profile different in size, flute profile amount of variability is very big, can influence for groove milling To tartar depth, judgement of the hoodle hole away from, hoodle hole angle of inclination, more efficient anti-copying means are formed.

In addition to the implementation, the utility model also includes other embodiment, all to use equivalents or equivalent The technical scheme that substitute mode is formed, all should fall within the protection domain of the utility model claims.
