[0029] like Figures 1 to 4 As shown, this embodiment provides a crimping locking device, which is used to press a workpiece against the work platform 100. The crimping locking device includes a frame 1, an operating handle assembly 2, and a crimping assembly 3. One end of the operating handle assembly 2 is hinged to the frame 1. The crimping assembly 3 includes a crimping rod 31 and a movable cam 32. The crimping rod 31 has a first end 311 and a second end 312 that are relatively arranged. The first end 311 is hinged to the frame 1, and the second end 312 is used to crimp the workpiece. The movable cam 32 is fixedly connected to the crimping rod 31. The crimping rod 31 has a free state and a locked state. When the crimping rod 31 is in the locked state, the second end 312 presses the workpiece to restrict the workpiece to the work platform 100 to prevent the workpiece from shaking or moving. The crimping rod 31 is movably connected to the operating handle assembly 2. The operating handle assembly 2 can move along the contour surface of the movable cam 32 and drive the crimping rod 31 to rotate around its own first hinge shaft 313, so that the crimping rod 31 is converted from a free state to a locked state. When the crimping rod 31 is in the locked state, the highest point of the protrusion of the movable cam 32 can prevent the operating handle assembly 2 from moving in the opposite direction so that the crimping rod 31 remains in the locked state, thereby tightly crimping the workpiece on the work platform 100, preventing the crimping fixation of the crimping rod 31 from failing during the maintenance operation, and reliably locking the workpiece. When it is necessary to release the crimping fixation of the crimping rod 31 on the workpiece, the operating handle assembly 2 is rotated in the opposite direction so that it passes the highest point of the protrusion of the movable cam 32, and the crimping rod 31 can be restored to a free state. The crimping locking device has a simple structure, is lightweight, and is easy to use. The locking and unlocking operations only require rotating the operating handle assembly 2.

[0030] In one embodiment, the operating handle assembly 2 includes a handle bar 21 and a driving member 22. One end of the handle bar 21 is hinged to the frame 1, and the driving member 22 is connected to the handle bar 21. The second hinge axis 211 and the first hinge axis 313 of the handle bar 21 are spaced apart, and the handle bar 21 and the pressing rod 31 are cross-connected. When the handle bar 21 rotates about the second hinge axis 211, the driving member 22 can abut the movable cam 32 and move along the contour of the movable cam 32 to drive the pressing rod 31 to rotate. In other words, the handle bar 21 drives the pressing rod 31 to rotate by the driving member 22 moving along the contour of the movable cam 32.

[0031] In order to reduce the friction between the driving member 22 and the movable cam 32 , the driving member 22 is a roller, which is rotatably connected to the handle rod 21 and rolls against the contour surface of the movable cam 32 .

[0032] In one embodiment, the handle bar 21 includes a first shaft 212 and a second shaft 213. The first shaft 212 and the second shaft 213 are parallel to each other and detachably connected. A roller is clamped between the first shaft 212 and the second shaft 213. A guide gap 214 is formed between the first shaft 212 and the second shaft 213. The pressing rod 31 is inserted into the guide gap 214 to cross the pressing rod 31. The first shaft 212 and the second shaft 213 constrain the pressing rod 31, ensuring that the pressing rod 31 is always in a cross-connected state with the handle bar 21, facilitating the handle bar 21 to drive the pressing rod 31 to switch states.

[0033] To enhance the reliability of the locking mechanism of the pressing rod 31, the operating handle assembly 2 further includes a locking member 23 connected to the handle rod 21. The locking member 23 has a locking surface 231 that aligns with the contour of the movable cam 32. When the pressing rod 31 is locked, the locking surface 231 abuts against the contour of the movable cam 32, restricting reverse rotation of the pressing rod 31. Friction is generated between the locking surface 231 and the contour of the movable cam 32, preventing the movable cam 32 from moving and unlocking, thereby enhancing the reliability of the locking mechanism.

[0034] In order to make the locking surface 231 and the contour surface of the movable cam 32 fit better, the operating handle assembly 2 also includes an elastic member 24, one end of the elastic member 24 is connected to the handle rod 21, and the other end is connected to the locking member 23. The elastic member 24 always has the tendency to drive the locking member 23 to move toward the direction of pushing the movable cam 32 so that the crimping rod 31 remains in a locked state.

[0035] Specifically, the elastic member 24 is an elastic pin, and the locking member 23 is rotatably connected to the handle bar 21. The locking member 23 also includes a connecting portion 232. The connecting portion 232 and the locking surface 231 are located on either side of the rotating shaft, forming an inverted T-shaped structure. The elastic pin elastically abuts the connecting portion 232 to drive the locking member 23 to rotate. The elastic pin elastically pushes against the connecting portion 232, causing the locking member 23 to rotate, thereby improving the fit between the locking surface 231 and the contour of the movable cam 32. Furthermore, this elastic abutment prevents the movable cam 32 and the elastic member 24 from becoming stuck.

[0036] In order to constrain the crimping rod 31 in a free state, the frame 1 is provided with a stopper 11. The crimping rod 31 in a free state can abut against the stopper 11. The stopper 11 is used to abut and limit the reverse rotation of the crimping rod 31, thereby preventing the crimping rod 31 from rotating in the reverse direction at too large an angle and generating an impact force on the handle rod 21.

[0037] To enable the crimping and locking device to be used on equipment, the frame 1 is provided with a mounting hole 12. A fastener passes through the mounting hole 12 and is removably connected to the equipment on which the work platform 100 is located. Specifically, the frame 1 can be installed at a corresponding position on the equipment based on the position of the work platform 100 to ensure the relative position of the crimping assembly 3 and the workpiece is accurate. The equipment includes but is not limited to cigarette making equipment.

[0038] In one embodiment, the work platform 100 includes a first limit plate 101 and a second limit plate 102 arranged at an angle. The first limit plate 101 and the second limit plate 102 are positioned on either side of a workpiece. The crimping rod 31 crimps the workpiece to position it within the angle and abut against the first and second limit plates 101 and 102, thereby constraining the workpiece. The second end 312 has a crimping arc surface 3121, which creates linear contact with the workpiece to prevent scratches.

[0039] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
