Description

Clutch device for lock body

Technical Field

The utility model belongs to the technical field of the lock body, refer in particular to an engaging and disengaging gear for lock body.

Background

At present, most lock bodies are double-movable and double-quick in the using process, so that the steps of the lock bodies in the processing and assembling process are more, and the production cost is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a stable in structure, production efficiency height, low in production cost's clutch for lock body.

The purpose of the utility model is realized like this: a clutch device for a lock body comprises a shifting block, a clutch block which is rotatably arranged in the shifting block and a square rod which is arranged in the clutch block and the shifting block in a penetrating way, wherein an annular groove is formed in the upper end surface of the shifting block; the outer wall of the upper end of the clutch block is provided with a clamping block, the clamping block is slidably arranged in the annular groove, one end in the annular groove is provided with a fixing piece, and the fixing piece is fixedly arranged on the lock body; the clutch block is provided with a clutch hole perpendicular to the square rod, and the clutch hole is clamped with a clutch pin penetrating through the outer wall of the shifting piece block.

Preferably, the outer wall of the shifting piece block is provided with an opening, and a fixed block for limiting the clutch pin on the shifting piece block and a return spring for controlling the clutch pin to keep an initial position under the condition of no external force are arranged in the opening; when the clutch pin overcomes the elasticity of the return spring and is inserted into the clutch hole, the lock body is in an unlocking state, otherwise, the lock body is in a locking state.

Compared with the prior art, the utility model outstanding and profitable technological effect is: the utility model discloses a clutch has reduced the quantity of square bar for traditional lock body with two square bars to reduce lock body manufacturing cost and increased the efficiency of its processing and assembly.

FIG. 1 is one of the schematic structural diagrams of the present invention;

FIG. 2 is a second simplified structural diagram of the present invention;

fig. 3 is a schematic view of the present invention.

Detailed Description

The invention will be further described with reference to specific embodiments.

As shown in fig. 1-3, a clutch device for a lock body comprises a shifting piece block 1, a clutch block 2 rotatably arranged in the shifting piece block 1, and a square rod 3 penetrating through the clutch block 2 and the shifting piece block 1, wherein an annular groove 4 is formed in the upper end surface of the shifting piece block 1; the outer wall of the upper end of the clutch block 2 is provided with a clamping block 5, the clamping block 5 is slidably arranged in an annular groove 4, one end in the annular groove 4 is provided with a fixing piece 6, and the fixing piece 6 is fixedly arranged on the lock body; the clutch block 2 is provided with a clutch hole 7 vertical to the square rod 3, and the clutch hole 7 is clamped with a clutch pin 8 penetrating through the outer wall of the shifting block 1.

Compared with the traditional lock body with two square rods 3, the clutch device of the technical scheme reduces the number of the square rods 3, thereby reducing the production cost of the lock body and increasing the processing and assembling efficiency of the lock body.

Preferably, an opening 9 is formed in the outer wall of the disc-pulling block 1, a fixing block 10 for limiting the clutch pin 8 on the disc-pulling block 1 and a return spring for controlling the clutch pin 8 to keep an initial position under the condition of no external force are arranged in the opening 9; when the clutch pin 8 overcomes the elasticity of the return spring and is inserted into the clutch hole 7, the lock body is in an unlocking state, otherwise, the lock body is in a locking state.

When a user uses the lock body, the motor in the lock body presses the clutch pin when the outer door plate sends a signal to the lock body through a fingerprint or a password, the clutch pin 8 is clamped in the clutch hole 7, the square rod 3 is rotated to drive the clutch block 2 to rotate, and the clamping block 5 drives the shifting block 1 to rotate to one side of the fixing part 1 all the time to realize the unlocking process; in the figure, the position of the clamping block 5 on the clutch block 2 is the position of the handle when the handle is normal, when a user needs to lock, the clutch pin 8 is not in the clutch hole 7, the square rod 3 rotates in the opposite direction, and the clamping block 5 abuts against one end, far away from the fixing piece 6, of the annular groove 4 at the moment, so that the whole poking piece block 1 is pushed to move, and locking is achieved.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
