Abstract

The utility model discloses a lockset which comprises a lock case, a key cylinder and a key; the utility model is characterized in that a lock blade (4) and a rubber post (5) are provided in the key cylinder (2); a setback type arc (4-1) is provided in the center hole of the lock blade (4); furthermore, a semicircle gap (4-2) is provided on the lock blade; semicircle posts (3-1) in different radius are provided on a key 3; the center holes of the lock blade (4) of the setback type arc (4-1) match with the semicircle posts (3-1) of the key (3) which matches with the lock blade. The semicircle posts of the key are assembled at random; with the corresponding assembly of the lock blade in the key cylinder, the accuracy of opening and closing the lockset increases and the publicity rate between the locksets is lowered; moreover, the processing of the key is convenient and the safety factor of the lockset is high. The lockset designed according to the design motif in the utility model offers positive application effect to all users.

Description

A kind of lockset

Technical field

The utility model relates to a kind of improvement invention of lockset.

Background technology

In the prior art, structure thousand strange hundred samples of lockset, structure is different, a kind of lockset is wherein arranged, also be provided with locking plate in its lock core, the lockhole shape of this locking plate also will match with its key, the form that this locking plate lockhole matches with key has two kinds, a kind of is groove milling on the arc surface of key, this groove that mills is that its radian with radian mills into 10 ° according to locking plate sheet number, 30 °, 50 °, the number of degrees variation according to groove reaches the lockmaking purpose then, and also having a kind of is to become 10 ° before key is got on the bus, 30 °, 50 ° of different gradients, reach the purpose of lockmaking according to the variation of gradient, above-mentioned dual mode, no matter employing is any, the processing of its key is very inconvenient, the bigger error of the number of degrees can appear man-hour adding, also very unstable when unblanking, can open sometimes, difficulty is opened sometimes, mutual opening rate between each lockset is higher, and safety factor is also lower.

Summary of the invention

In view of the problem that known technology exists, it is easy to process that the purpose of this utility model aims to provide a kind of key, the accuracy of unblanking height, stable performance, and the lock that mutual opening rate is low and safety factor is high is individual.For achieving the above object, the utility model takes following mode to finish: this lockset includes lock housing, lock core and key, be provided with locking plate and rubber column in the described lock core, the centre bore of described locking plate is provided with the step circular arc and is provided with half round cut on locking plate, the described semicolumn that is provided with different radii on the key, the described locking plate centre bore that is provided with the step circular arc follows the semicolumn on the key that matches with it to be complementary, locking plate in the described lock core is identical with the quantity of semicolumn on the key, it is highly identical for the different semicolumn of described radius on the key, and the setting angle unit of differing of each locking plate upper semi-circle breach is 30 °.

The utility model is because employing semicolumn arbitrary combination on the key, following the interior locking plate of lock core along with respective combination, accuracy height when lockset is opened and closed, the mutual opening rate of asking of each lockset is low, and the key of this lockset is easy to process, the safety factor height of lockset, and the half round cut setting angle unit on the locking plate is 30 °, accurately putting in place when making key turns, according to the lockset of the utility model design motif made, will be that vast house user brings positive result of use.

Description of drawings

The utility model has following accompanying drawing:

Fig. 1 is the structural representation of the utility model after decomposing;

State diagram when Fig. 2 is the locking of the utility model lock core;

State diagram when Fig. 3 spends for the utility model lock core rotation 60;

State diagram when Fig. 4 unblanks for the utility model lock core.

The specific embodiment

Accompanying drawing has been represented structure of the present utility model and embodiment, further describes each relevant details of embodiment below more in conjunction with the accompanying drawings.This kind lockset, include lock housing 1, lock core 2 and key 3, be provided with locking plate 4 and rubber column 5 in the described lock core 2, the elasticity of described rubber column 5 its rubbers of usefulness is withstood locking plate 4, make the locking plate 4 can't rotation, the centre bore of described locking plate 4 is provided with step circular arc 4-1, and on locking plate 4, be provided with half round cut 4-2, described key 3 is provided with the semicolumn 3-1 of different radii, described locking plate 4 centre bores that are provided with step circular arc 4-1 follow the semicolumn 3-1 on the key 3 that matches with it to be complementary, the quantity of semicolumn 3-1 on locking plate 4 in the described lock core 2 and the key 3 is identical, that is to say that several semicolumn 3-1 are arranged, several locking plates 4 that are complementary with semicolumn 3-1 are so just arranged, it is highly identical for the different semicolumn 3-1 of radius on the described key 3, and the setting angle unit of differing of each locking plate 4 upper semi-circle breach 4-2 is 30 °.Separate with partition 6 between each locking plate 4, partition 6 and lock core 2 do not disturb when rotating mutually.In the present embodiment, key 3 is provided with three kinds of different semicolumn 3-1 of height same outer diameter as, its external diameter is respectively 7mm, 6mm, 5mm, we are with each semicolumn called after A ', B ', C ', equally, each locking plate that is complementary with it is with its called after A, B, C, semicolumn 3-1 on the present embodiment key 3 is provided with seven, it presses A ' B ' C ' C ' B ' C ' C ' in proper order, when so locking plate 4 being installed, just must put ABCCBCC in the lock core 2, put into shim 6 between each locking plate and the locking plate again, in lock core 2, put into lock 7 and rubber column 5 then, locking plate after the combination is inserted and buckled jump ring 8 in the lock housing 1, this moment, lock core 2 was blocking (as Fig. 3), during blocking, lock 7 is stuck in 2 of lock housing 1 and lock cores, and because the elastic reaction of rubber column 5, lock core 2 can't be rotated, owing to be the unit installation between the half round cut 4-2 of each locking plate with 30 °, when so key 3 rotates, can be with 30 °, 60 ° of rotations, when key 3 rotates, semicolumn A ' drive locking plate A on the key 3 rotates 60 °, makes the half round cut 4-2 on the locking plate A aim at lock 7, because of semicolumn B ' external diameter on the key less, idle running earlier just can be met locking plate B for 30 °, only drive the locking plate rotation and make locking plate B upper semi-circle notch alignment lock for 30 °, in the present embodiment, locking plate C just makes the half round cut 4-2 on it aim at lock when installing, and, can not drive locking plate and rotate because the semicircle external diameter on the key 3 that is complementary with it is less.After the half round cut 4-2 of above-mentioned three kinds of locking plates all aimed at lock 7, key 3 again, drove lock core 2 and rotated, and at this moment, lock 7 slips into lock core 2, breaks away from locking plate, and lock housing 1 is blocked and unblanked.
