Detailed ways

An automatic lock body with a clutch device for handle unlocking of the present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

As shown in Figures 1 to 6, in a preferred embodiment, an automatic lock body with a handle unlocking and clutch device of the present invention includes a lock body shell 1 and a lock tongue assembly 2, and also includes a lock body for driving the lock tongue. The motor assembly 3 that the assembly 2 moves, the lock body housing 1 is also provided with a handle connection assembly 4, a drive assembly 5, a gear assembly 6 and a clutch device 7, the motor assembly 3 is connected with the gear assembly 6 and can drive the gear assembly 6 rotate, the gear assembly 6 is connected with the deadbolt assembly 2 and can drive the deadbolt assembly 2 to move; the clutch device 7 is arranged between the motor assembly 3 and the gear assembly 6, and can connect the motor assembly 3 and the gear assembly 6. The synchronous rotation state is switched to connection or separation. Since the motor assembly will limit the rotation of the gear assembly, the mechanical unlocking can be easily achieved only when the motor assembly and the gear assembly 6 are separated; the handle connection assembly 4 is connected to the handle outside the lock body, and when the handle drives the handle When the connecting assembly 4 rotates, the clutch device 7 is first opened, and then the locking tongue assembly 2 is driven to move by the driving assembly 5, so as to realize the smooth and fast operation of the mechanical handle switch lock at any time.

In this embodiment, the handle connection assembly 4 includes a main tongue shifting block 41, and also includes a main tongue driving piece 43 and a reversing piece 44 that are sleeved on the main tongue shifting block 41 and rotate synchronously with the main tongue shifting block 41, The reversing piece 44 is provided with a flange 441 for pushing the clutch device 7, and a column 442 for driving the main tongue driving piece 43; The reversing piece 44 and the main tongue driving piece 43 are rotated synchronously by the extension portion 432 that drives the driving assembly 5 to rotate. When the handle connection assembly 4 rotates, it preferentially drives the main tongue shifting block 41 to rotate, and the main tongue shifting block 41 then drives the reversing piece 44 to rotate. The motor assembly 3 does not rotate with the gear assembly 6, and at the same time drives the main tongue driving piece 43 to rotate through the upright column 442, and the extension 432 on the main tongue driving piece 43 drives the driving component 5 to rotate, and the driving component 5 rotates to drive the lock tongue. Telescopic to achieve door lock switch.

The handle connection assembly 4 also includes a main tongue paddle 42 and a reversing screw 45. The main tongue paddle 42 is sleeved on the main tongue paddle 41 and rotates synchronously with the main tongue paddle 41. The main tongue paddle 41 is connected to the main tongue paddle 41. The tongue paddle 42 can also be designed as a part, and the reversing screw 45 can detachably connect the main tongue paddle 42 and the reversing piece 44 to realize the synchronous rotation of the main tongue paddle 42 and the shifting paddle 44 . At this time, the main tongue switch piece 42 and the main tongue switch piece 41 have matching edges, that is, they can rotate synchronously through the action of the at least one edge, and the main tongue drive piece 43 and the reversing piece 44 are sleeved on the main tongue switch The cavity at the block 41 is circular, and the rotation of the main tongue shifting block 41 will not directly drive the main tongue driving piece 43 and the reversing piece 44 to rotate, but first drive the main tongue shifting piece 42, and then drive it through the reversing screw 45. The reversing piece 44 rotates, and finally the column 442 on the reversing piece 44 drives the main tongue driving piece 43 to rotate.

More optimally, in order to better use the door lock and realize the separate control of different combinations of the left door and the right door or the inner door and the outer door, the main tongue paddle 41 and the main tongue paddle 42 are one on the front and the bottom on the top. , the main tongue paddle 42 is sleeved on the main tongue paddle 41 and rotates synchronously with the main tongue paddle 41, and a gasket 46 is arranged between the two main tongue paddles 41 to ensure that the square bar connecting the handle and the handle assembly is The combination of the main tongue and one of the main tongues is fast linked, so that the front and rear main tongues 41 can be rotated independently. At the same time, by setting the reversing screw 45 on one of the main tongue picks 42, the reversing screw 45 detachably connects one of the main tongue picks 42 and the reversing piece 44, so as to realize one of the main tongue picks The plate 42 rotates synchronously with the reversing plate 44, so that one lock body can adapt to different combinations of left, right and inner and outer door openings, meet the installation requirements of different door opening methods, and realize the versatility of the product.

More optimally, the lock tongue assembly 2 includes a lock tongue 21 and a drive block 22 fixed on the lock tongue 21. A rack 221 is provided on one side of the drive block 22. The rack 221 is matched with the gear assembly 6, and the motor assembly 3. Drive the gear assembly 6 to rotate through the rotating shaft, so as to drive the lock tongue 21 to move through the rack 221.

In order to ensure the stability of the clutch device 7, the clutch device 7 includes a clutch paddle 73, a clutch gear 71, a clutch moving block 72 and a manual clutch bracket 74; the clutch gear 71 is sleeved on the rotating shaft of the motor assembly 3, and the clutch gear 71 It rotates relative to the rotating shaft and is connected with the gear assembly 6; the clutch moving block 72 is sleeved on the rotating shaft of the motor assembly 3 and rotates synchronously with the rotating shaft. The manual clutch bracket 74 can drive the clutch moving piece 73 to move, and the clutch moving piece 73 can drive the clutch moving block 72 Separated from the clutch gear 71 . The front end of the manual clutch bracket 74 is connected with the lock body shell 1 as a rotating point, and the rotating connection can be a rotating column, a bolt, a bearing or other rotatable connection; When rotating, its flange 441 contacts with the push column 741 to push the manual clutch bracket 74; the rear end of the manual clutch bracket 74 can contact with the clutch paddle 73 and push the clutch paddle 73 to move to realize the ejection of the clutch device 7; A return spring 75 is provided between the clutch moving block 72 and the motor assembly 3 . When the force of the clutch paddle 73 acting on the clutch moving block 72 is removed, the return spring 75 pushes the clutch moving block 72 to engage with the clutch gear 71 . In addition, the clutch paddle 73 is provided with a bayonet 731 near the clutch bracket 74, and the lower end of the clutch bracket 74 is snapped into the bayonet 731; the clutch paddle 73 is provided with a blocking piece 732, and the blocking piece 732 is clamped on the clutch paddle 732. On the moving block 72 , the clutch moving block 72 can be provided with a bayonet, groove, protrusion and other structures that cooperate with the blocking piece 732 , all of which can achieve the technical effect of using the blocking piece 732 to push the clutch moving block 72 to move. When the door handle is rotated, the flange 441 on the reversing piece 44 in the handle connecting assembly 4 pushes the push column 741. Due to the S-shaped structure of the manual clutch bracket 74, its rear end is a free end, and the free end can drive the clutch. The paddle 73 moves, and the blocking piece 732 on the clutch paddle 73 pushes the clutch moving block 72 away from the clutch gear 71 to realize the opening of the clutch device 7, and the motor assembly 3 no longer affects the rotation of the gears in the gear assembly 6, which can be easily Handle unlocking. When the handle is released, under the action of the return spring 75, the clutch moving block 72 engages in the clutch gear 71 again to realize linkage.

In this embodiment, one side of the rotating shaft of the motor assembly 3 is a plane, and correspondingly, the middle hole of the clutch moving block 72 is a corresponding half tooth shape, that is, the clutch moving block 72 can be driven to rotate by the plane on the rotating shaft, and the clutch gear The middle hole of 71 which is sleeved on the rotating shaft is circular and may not rotate with the rotating shaft. Similarly, the rotating shaft can also have other edge shapes, which can also achieve the same technical effect.
