Embodiment 1

[0037] A pressing device for a lock head. The lock head 1 includes a lock seat 10 and a pressing device 11. The pressing device 11 includes a mounting seat 112, a pressing part 111, two sets of rotating shafts and a one-way Bearings, both ends of the pressing part 111 are embedded with a first one-way bearing 114 and a second one-way bearing 116 with different inner diameters. One end of the first rotating shaft 113 is fixedly connected to the mounting seat 112, and the other end is connected to the first one-way The bearing 114 is rotatably connected, and the pressing part 111 and the first one-way shaft 114 rotate coaxially to realize the one-way rotation of the pressing part 111;

[0038] Further, one end of the second rotating shaft 115 passes through the second one-way bearing 116 and is rotatably connected with the mount 112, and the other end passes through the first one-way bearing 114 and the first rotating shaft 113 and is rotatably connected with the mount 112; The ...

Embodiment 2

[0041] On the basis of Embodiment 1, a one-way locking buckle includes a lock head 1 and a lock tongue 2 made of elastic material. The lock head 1 includes a belt threading groove 12, a lock seat 10 and the embodiment The above-mentioned pressing device 11, the threading groove 12 is connected with the lock seat 10, the pressing device 11 is hinged with the lock seat 10 through the hinge shaft 6, and one end of the hinge shaft 6 is connected to the concave shape on the pressing part 4 of the pressing device 11. The limiting groove 41 abuts, and a gap for the lock tongue 2 to pass is provided between the pressing device 11 and the lock seat 10 .

[0042] Specifically, the pressing part of the pressing device 11 is a ratchet 111 structure, and the pressing device 11 also includes a mounting seat 112, a first rotating shaft 113 and a first one-way bearing 114, and the mounting seat 112 is fixed to the lock seat 10. A rotating shaft 113 is fixed to the mounting seat 112, the first...

Embodiment 3

[0051] A buckle with one-way locking. The difference from the second embodiment is that an elastic member is provided between the lock seat 10 and the mounting seat 112 for pressing the ratchet wheel 111 against the dead bolt 2. The elastic member is a pressing Tighten the double torsion spring 7, the compression double torsion spring 7 is sleeved on the peripheral side of the hinge shaft 6, the central axis of the compression double torsion spring 7 abuts against the mounting seat 112 of the compression device 11, and the two legs are respectively connected to the lock seat 10, and the pressing device 11 is in tight contact with the deadbolt 2 by pressing the double torsion spring 7. In this way, with the hinge shaft 6 as the center, by compressing the elastic force of the double torsion spring 7, the lock seat 10 is rotated in a direction away from the dead bolt 2, and the ratchet 111 can be separated from the dead bolt 2, thereby releasing the ratchet 111 against the lock. ...

Abstract

The invention relates to the technical field of fastening belts, and provides a pressing device of a lock head and a one-way locking lock catch comprising the pressing device. The one-way locking lock catch comprises the lock head and a spring bolt; the lock head comprises a lock base, a belt penetrating groove and the pressing device; the pressing device comprises a pressing part, at least two sets of rotating shafts and one-way bearings used in cooperation with the rotating shafts; one-way bearings with different inner diameters are embedded in the two ends of the pressing part side by side, and rotating shafts matched with the one-way bearings are arranged in the one-way bearings in a sleeved mode; one end of the first rotating shaft is fixedly connected with an installation base, and the other end of the first rotating shaft is rotationally connected with the first one-way bearing; the inner diameter of the first one-way bearing is larger than that of the second one-way bearing; and the first one-way bearing and the second one-way bearing rotate coaxially. The one-way locking lock catch can achieve one-way locking and fine adjustment functions through transmission matching of the one-way bearings with different inner diameters and the rotating shafts, so that the problems that an existing one-way lock catch is complex in structure and locking operation, and fine adjustment and unlocking rollback cannot be achieved are solved.

Description

technical field [0001] The invention relates to the technical field of fastening belts, in particular to a pressing device for a lock head and a one-way locking buckle comprising the same. Background technique [0002] A lock is an object used to fasten two items. It is generally composed of a movable part and a fixed part. Locking and unlocking are achieved through the combination and separation of the movable part and the fixed part. The one-way locking seat belt buckle is one of the buckles. It is widely used in the bandages of bandaging products, various belts or various seat belts. A device that is fastened by a seat belt and can be released quickly. [0003] The current one-way locking seat belt buckle still has some problems in the process of assembly and use: the structure is complex, there are difficulties in assembly, and the cost is too high due to the complex structure, and the locking operation is complicated, or it can only be locked , it is impossible to fin...
