Abstract

The utility model discloses a lockset, particularly a trick lockset, which comprises a coding lock device. The utility model is characterized in that an inner hole 13 of a coding wheel 12 on the coding lock is matched with a key shell 7; the interior of the key shell 7 is provided with a key 6; the key 6 and the key shell 7 form a slide way fit; one end of the key 6 is provided with a key hole 10; the key hole 10 is matched with an end 14 of a trick key 3. The utility model has the advantages of multiple insurance, close fit among locks, mutually promoted functions, trick tooth shape, not easy imitation, etc.

Description

Built-in lock

The utility model belongs to a kind of lockset, particularly a kind of built-in lock.

Present cabinet door lock tool, especially silver-colored cabinet etc. all adopt cipher wheel lockset, built-in lock etc., cooperation useless between each lock, the function that can only finish out separately or lock, also have shaped as key bit expose, easily by imitated shortcoming.

The built-in lock of many insurances that the purpose of this utility model provides that a kind of cipher wheel lock cooperatively interacts with other locksets, mutually promote on the function, profile of tooth is hidden.

Technical solution of the present utility model is: a kind of built-in lock, comprise coded lock device, it is characterized in that: the endoporus 13 and the key shell 7 of the cipher wheel 12 on the coded lock match, be provided with key 6 in the key shell 7, cooperate for slideway between key 6 and the key shell 7, key 6 one ends are provided with keyhole 10, and keyhole 10 cooperates with the termination 14 of built-in key 3.

The endoporus of described cipher wheel 12 is square hole or polygon hole or elliptical aperture.

The utility model compared with prior art has advantages such as multilayer is insured, respectively promotion mutually, profile of tooth are hidden on close fit, the function between the lock, difficult quilt is imitated.

Below in conjunction with the drawings and the specific embodiments the utility model is further described:

Fig. 1 is the utility model specific embodiment structural representation.

As shown in the figure: 1 is the cabinet door, on cabinet door 1 coded lock device is installed, and which is provided with door lock lockhole 11 and cipher wheel 12.The endoporus 13 of cipher wheel 12 is a square hole.The appearance of key shell 7 is square, matches with endoporus 13, and promptly key shell 7 can insert in the endoporus 13.Endoporus 13 also can adopt rectangular with the shape of key shell 7 appearances or other polygons or oval the cooperation.

A key 6 is arranged in shell 7, and there is a built-in keyhole 10 rear end of key 6, on key shell 7 inside walls slideway 8 is arranged, and the rear end of key 6 has boss to cooperate with slideway 8.Be provided with pellet shot from a slingshot 9 and spring on the lockset between key 6 rear ends and the key shell 7.The profile of tooth of key 6 is hidden in the key shell 7, does not expose.

Built-in keyhole 10 matches with the termination 14 of built-in key 3.One termination of built-in key 3 has driving lever 4.Built-in at ordinary times key 3 places in the door 1, and stretch out outside the door 1 from the long slot bore 2 on the door 1 termination of driving lever 4.One end door 1 of long slot bore 2 is provided with the long slot bore 5 placing or take out key shell 7.

Use is as follows: when opening the door, earlier key shell 7 is put into door 1, position as shown in the figure together with the key in it 6 from long slot bore 5.Rotational password wheel 12 aligns the square inner bore of all cipher wheel 12, stirs driving lever 4 more to the left, built-in key 3 is moved to the left, and insert in the built-in keyhole 10 termination 14, and the tooth top on the termination 14 is to pellet shot from a slingshot 9 at this moment, key 6 can be moved to the left along slideway 8, continuation is to left translation, and key shell 7 moves in the endoporus 13, and key 6 inserts in the door lock lockhole 11, the rotational password wheel 12 again, can drive key shell 7 and rotate, drive key 6 again and rotate, reach the purpose of opening the door.Stir driving lever 4 at closing time to the right, key 6 is brought back to as shown in the figure position by the tooth on the termination 14.Key 6 also takes out thereupon when taking out key shell 7.

Claims

1. built-in lock, comprise coded lock device, it is characterized in that: the endoporus (13) of the cipher wheel on the coded lock (12) matches with key shell (7), be provided with key (6) in the key shell (7), cooperate for slideway between key (6) and the key shell (7), key (6) one ends are provided with keyhole (10), and keyhole (10) cooperates with the termination (14) of built-in key (3).

2. built-in lock according to claim 1 is characterized in that: the endoporus of described cipher wheel (12) is square hole or polygon hole or elliptical aperture.
