Referring to fig. 1 to 2, an embodiment of the present utility model provides a stepless quick lock device 1, which includes a handle 10, an unlocking trigger assembly 20, a conical disk 30, a sleeve 40 and a lock cylinder 50. The conical disc 30 is sleeved on the sleeve 40, the lock cylinder 50 is fixed through the sleeve 40 and the handle 10, and the unlocking touch assembly 20 is mounted on the handle 10. When the unlocking touch assembly 20 is abutted with the conical disc 30, self-locking is completed. That is, when the unlocking trigger assembly 20 abuts against the conical disc 30, the locking mechanism is in a self-locking state. When the unlocking trigger assembly 20 is pressed, the unlocking trigger assembly 20 pushes the conical disk 30 downward, and the handle 10 can be rotated downward, thereby unlocking. Compared with the mode of realizing the advanced anti-loosening through a ratchet wheel, the utility model realizes the stepless anti-loosening through the conical disk, namely, the anti-loosening is immediately performed on a locking point, and the condition of loose locking can not occur.

In some embodiments, the sleeve 40 is a restraining sleeve, and the sleeve 40 includes a sleeve body and a ring 420. The ring 420 is sleeved on the sleeve body, so as to divide the sleeve body into a first sleeve body 411 and a second sleeve body 412. The first sleeve body 411 is sleeved with a first spring 11, one end of the first spring 11 abuts against the circular ring 420, and the other end of the first spring 11 abuts against the conical disc 30. The second sleeve body 412 is sleeved with a second spring 12, one end of the second spring 12 abuts against the ring 420, and the other end of the second spring 12 abuts against the box body.

In some embodiments, the outer surface of the lock cylinder 50 is provided with external threads 510, the inner wall of the sleeve body is provided with internal threads (not shown) matched with the external threads 510, and the lock cylinder 50 and the sleeve 40 are connected through the internal threads and the external threads 510.

In some embodiments, the unlock trigger assembly 20 includes a button 210, a trigger 220, and a connector 230. One end of the trigger piece 220 is fixed to the button 210, and the other end of the trigger piece 220 abuts against the conical disk 30. The middle part of the touch member 220 is provided with a through hole, the handle 10 is provided with a mounting hole with the same size as the connecting member 230, the connecting member 230 passes through the through hole and is fixed in the mounting hole of the handle 10, and then the touch release assembly 20 is fixed with the handle 10. Further, the handle 10 is a handle with a tapered opening, and a groove (not shown) is provided on the handle 10, and the button 210 is installed in the groove.

According to the stepless quick lock device provided by the embodiment of the utility model, through a stepless anti-loosening principle, the handle rotates upwards to be in a locking state, and rotates downwards to be in an unlocking state. The spring, conical disk, sleeve allow the handle to freely rotate upwards, but at any time limit the handle from rotating downwards. Only when the unlocking touch assembly is pressed, the conical disc is pushed down by the unlocking touch assembly, and the handle can rotate downwards at the moment, so that stepless anti-loosening can be realized, namely, the anti-loosening is immediately performed on a locking point, and the condition of loose locking can not occur.

In other embodiments, the utility model also provides a box body, and the two adjacent box bodies are locked and fixed by the stepless rapid locking device 1.
