Detailed Description

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1 to 7, an embodiment of a lock clutch mechanism of the present utility model is presented:

a lock clutch mechanism comprises a handle 1, a handle seat 2, a clutch seat 3, a reset torsion spring, a connecting bolt 5 and a limiting piece 4.

The handle 1 is arranged outside the lock shell 6 and penetrates through the lock shell 6 to be connected with the handle seat 2 in the lock shell 6 in a threaded connection mode, two arc-shaped handle protruding blocks 11 different in size are arranged at the tail end of the handle 1, a handle seat positioning groove 21 matched with the handle protruding blocks 11 is arranged on the handle seat 2, and the handle seat positioning groove 21 is matched with the handle protruding blocks 11 to avoid wrong installation direction during installation. In which a smaller handle projection 11 passes through and protrudes onto the outside of the handle seat 2. The handle seat 2 is provided with a handle seat connecting groove 22 on the side.

The clutch seat 3 is provided with a clutch seat connection hole 33 on a side surface thereof, which is adapted to the handle seat connection groove 22, and the clutch seat connection hole 33 is composed of an inner clutch seat connection hole 331 and an outer clutch seat connection hole 332 on an outer side, and the radius of the clutch seat connection hole 331 is smaller than that of the clutch seat outer connection hole 332. The outer side of the connecting bolt 5 is provided with an annular limiting clamping block 51 in a surrounding mode, and the radius of the annular limiting clamping block 51 is larger than that of the connecting hole 331 in the clutch base and smaller than that of the connecting hole 332 outside the clutch base. The connecting pin 5 is disposed in the clutch seat connecting hole 33, and when the external structure pushes the connecting pin 5, a portion of the connecting pin 5 on the front side of the annular limit clamping block 51 is inserted into the handle seat connecting groove 22 from the clutch seat connecting hole 33 so that the handle seat 2 is connected with the clutch seat 3. A return spring is arranged between the annular limiting clamping block 51 and the clutch seat connecting hole 331, and the external structure is reset through the return spring after stopping pushing.

The clutch seat 3 top is provided with the last clutch groove 32 of with spacing lug 41 adaptation, and clutch seat 3 top is provided with last clutch groove 32. The middle of the upper clutch groove 32 is provided with a clutch seat threaded hole 323, the center of the limiting piece 4 is provided with a limiting piece through hole 42, and a screw penetrates through the limiting piece through hole 42 to be in threaded connection with the clutch seat threaded hole 323, so that the limiting piece 4 is limited and arranged in the upper clutch groove 32. The bottom of the limiting piece 4 is provided with a limiting projection 41, and the top of the limiting piece 4 is provided with a limiting piece connecting groove for connecting with the lock body.

The lower clutch groove 31 is an arc-shaped groove, the handle lug 11 is arranged at one end in the lower clutch groove 31, and a first limit groove 321 with the same size as the limit lug 41 and an arc-shaped second limit groove 322 are arranged in the upper clutch groove 32.

When in use, if the limit bump 41 is arranged at the correct end of the second limit groove 322, namely, when the downward rotation is clockwise, the limit bump 41 is arranged at the clockwise starting end of the second limit groove 322, and when the downward rotation is anticlockwise, the limit bump 41 is arranged at the anticlockwise starting end of the second limit groove 322. Even if the clutch seat 3 and the handle seat 2 are connected through the connecting bolt 5 during upward rotation, the clutch seat 3 cannot drive the limiting piece 4 to rotate, namely, the upward rotation has no effect. When rotating downwards, the clutch seat 3 can drive the limiting part to rotate, so that the lock body is driven to move to open the door.

If the limit bump 41 is arranged in the first limit groove 321, the lower clutch groove is matched with the handle bump, so that no matter whether the left door is opened or the right door is opened, when the clutch seat 3 and the handle seat 2 are not connected through the connecting bolt 5, the downward rotation is not influenced, and when the handle rotates upwards, the handle can drive the clutch seat 3 to rotate, thereby driving the limit piece 4 to rotate through the clutch seat 3, and finally driving the lock body to rotate for locking. When the connecting bolt 5 is connected with the clutch seat 3 and the handle seat 2, the limiting piece 4 can be driven to rotate through the clutch seat 3 when the handle seat 2 rotates downwards, so that the lock body is driven to move to open the door.

The functions required by the locks with two different functions can be realized by changing the positions of the limit lugs 41 in the upper clutch grooves 32, thereby reducing the stock cost and the mold opening cost and improving the final economic benefit.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the present utility model and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the present utility model.
