Abstract

The utility model discloses a lock in particular to a mechanical code lock head. The code lock head consists of a dead bolt cylinder and a shell outside the cylinder. The utility model is characterized in that the cylinder has front and back two sections, the front section is the front cylinder for the dead bolt spring and the back section is the back cylinder connected with the lock body; the drive plates A and B are hanging between the front cylinder and the back cylinder; the drive plate A has convex points in the front and back sides and the drive plate B has convex point in the front side; the drive plate A, the drive plate B, the front cylinder and the back cylinder cover have inner sockets which can form a line. The utility model effectively solves the disadvantages of the common mechanical lock head and has the advantages of a simple structure and a reliable function.

Description

Trick lock

(1) technical field under

The utility model relates to a kind of lockset, particularly a kind of mechanical code tapered end.

(2) background technology

Tapered end in the lockset is divided into mechanical type and electronic type two classes at present, the electronic type tapered end is owing to cost of production height, unstable properties are difficult to apply, and mechanical type is occupied an leading position, but because development of science and technology, people have grasped the method for many unlatching tapered ends, cause its security performance to descend greatly.

(3) summary of the invention

The utility model provides a kind of effective trick lock that improves security performance in order to remedy the deficiencies in the prior art.

The utility model is achieved by the following technical solution:

A kind of trick lock comprises the lock housing of cylinder type lock core, lock core outside, and its special character is: before and after described lock core is divided into two sections, leading portion is for installing the preceding lock core of marble spring, and back segment is for connecting the rear lock core that lock body is unblanked; Be followed successively by dial A, the dial B that suspends between preceding lock core, the rear lock core, the both sides, front and back of dial A are respectively equipped with salient point, and the front side of dial B is provided with salient point; Dial A, dial B and preceding lock core, rear lock core have the interior cutter that can form a line.

Trick lock of the present utility model, the surface of described dial A, dial B have and are contained in the corresponding concave point of steel ball, spring in the lock housing.

The cylinder type lock core is divided into two sections of front and back, and preceding lock core is installed marble spring, and rear lock core connects lock body unblanks; Two groups of dials are put in the centre, with the circle card front and back two lock cores are fixed on lock housing inside, and two groups of dials that suspend all can rotate in lock housing.The key reverse side inserts, the salient point of rotatable preceding lock core afterbody, and drive dial A, the salient point behind the dial A drives dial B and resets to a bit, and lock core drive dial A resets to a bit before the counter-rotating then, makes dial A become a line with dial B and the interior scalpriform of front and back lock core.After extracting key, key is inserted from the front, rotation is unblanked again.

The utility model efficiently solves the drawback of standard machinery tapered end, has advantage simple in structure, dependable performance.

(4) description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is the structural representation of matched key of the present utility model;

Fig. 3 is the structural representation of the utility model lock housing;

Fig. 4 is a connection diagram of the present utility model.

Among the figure, 1 lock housing, 2 preceding lock cores, 3 rear lock cores, 4 dial A, 5 dial B, 6 salient points, 7 interior cutters, 8 concave points, 9 keys.

(5) specific embodiment

Accompanying drawing is a kind of specific embodiment of the present utility model.As Fig. 1, shown in Figure 4, this embodiment comprises the lock housing 1 of cylinder type lock core, lock core outside, and lock core is divided into two sections of front and back, and leading portion is for installing the preceding lock core 2 of marble spring, and back segment is for connecting the rear lock core 3 that lock body is unblanked; Be followed successively by dial A4, the dial B5 that suspends between preceding lock core 2, the rear lock core 3, the both sides, front and back of dial A4 are respectively equipped with salient point 6, and the front side of dial B5 is provided with salient point 6; Dial A4, dial B5 and preceding lock core 2, rear lock core 3 have the interior cutter 7 that can form a line.The surface of dial A4, dial B5 has and is contained in the corresponding concave point 8 of steel ball, spring in the lock housing.

As shown in Figure 2, this matched key 9, during positive the insertion, preceding leptoprosopy is in two dials and rear lock core 3, and rotate when unblanking in preceding lock core 2 wide of back, also has the effect of the front and back lock core of connection; When reverse side inserted, preceding leptoprosopy was in preceding lock core 2, and lock core 2 before rotating during with digital corresponding on the lock housing 1, can be used as the coded lock handle.

As shown in Figure 3, be carved with password figure on the lock housing 1.Main pellet shot from a slingshot, spring, steel ball, the password figure installed, with inside and outside card fixedly front and back lock core and two dials, and the effect that connects main lock body.

Its antitheft mode can have two kinds:

A, Jiang Men lock, after key 9 extracted from the front, key 9 is extracted its forward rotation from inserting preceding lock core 2 interior (this moment, key 9 can only be inserted in the preceding lock core 2) on the contrary after the week, make the interior cutter 7 in two dials interlaced, and the interior cutter in the front and back lock core 7 is cut off, be senior anti-theft modes this moment.

After B, Jiang Men lock, key 9 is extracted from the front, made interior cutter 7 in front and back lock core and two dials also on a line, key 9 can directly insert when unblanking, and this is common anti-theft modes.

Claims
