The terms or positional relationships of the orientations of "upper", "lower", "left", "right", "front", "rear", etc. described in the embodiments are based on the orientation of the wearer's body in fig. 1, and are merely for convenience in describing the present utility model and simplifying the description, and are not intended to indicate or imply that the apparatus or elements must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the scope of the present utility model.
Example 1A self-locking buckle
As shown in fig. 1 to 5, the present embodiment includes a latch base 11, a latch plate 12 for clamping an object to be locked is rotatably connected to a surface of the latch base 11, a gap for passing through the object to be locked is left between a rotation center of the latch plate 12 and the latch base 11, and when in use, the latch plate 12 is rotated to press the object to be locked passing through the gap against the latch base 11. The object to be fastened is a shoelace 8 in this embodiment.
Specifically, as shown in fig. 1, a rotation shaft 9 is disposed in the middle of the latch base 11, the rotation shaft 9 is parallel to the latch base 11, an arc latch plate 12 bent to the latch base is rotatably connected to the rotation shaft 9, that is, the rotation center of the latch plate is a portion corresponding to the rotation shaft, in this embodiment, cylindrical rotation heads may be disposed on two side surfaces of the latch plate 12, and the rotation heads may be rotatably clamped into the latch base 11 to realize rotation connection; the end of the locking piece 12 contacting with the shoelace 8 is a smooth locking part 13, and the locking part 13 is made of rubber.
The distance between the rotation shaft 9 and the locking portion 13 on the locking piece 12 is greater than the distance between the rotation shaft 9 and the locking base 11. In use, the self-locking device 1 is in an open state, see figure 2. The shoelace 8 is passed through the gap between the locking piece 12 and the locking base 11, and then the locking piece 12 is folded in the direction of the arrow in fig. 2, so that the locking part 13 is contacted with and clamped with the shoelace 8, and the shoelace 8 is clamped without damaging the shoelace 8 due to the smooth end of the rubber material of the locking part 13.
The shoelace 8 passes through the gap state of the self-locking buckle 1 as shown in fig. 3, the locking buckle piece 12 is rotated according to the arrow direction as shown in fig. 3, and the distance between the rotating shaft 9 and the locking part 13 on the locking buckle piece 12 is larger than the distance between the rotating shaft 9 and the locking buckle base 11, so that the locking part 13 on the locking buckle piece 12 is in a vertical state with the locking buckle base 11 at one moment in the rotating process, at the moment, the shoelace 8 and the locking buckle base 11 which are contacted with the locking part 13 are deformed due to extrusion, and at the moment, the locking buckle piece 12 is in the tightest state for propping the shoelace 8, see fig. 4; continuing to rotate the latch tab 12 in the direction of the arrow in fig. 3, the position of fig. 5 is finally reached, at which point the shoelace 8 is fully tightened against the latch base 11. The key to locking the shoelace 8 is, among other things, the position of fig. 5.
If the shoelace 8 has a downward sliding trend, the locking portion 13 contacting with the shoelace 8 will also have a downward sliding trend, but at this time, the end of the locking piece 12 away from the locking portion 13 is already in tight contact with the locking base 11, even if the shoelace 8 has a downward sliding trend, the self-locking buckle 1 will not be opened, and natural loosening of the shoelace 8 is avoided.
The distance between the rotating shaft 9 and the locking part 13 on the locking piece 12 is not more than the sum of the distance between the rotating shaft 9 and the locking base 11 and the maximum deformation generated by the locking base 11, otherwise, the locking part 13 is already abutted against the locking base 11 and cannot rotate to the position of fig. 5 when the locking piece 12 is not in the vertical state between the locking part 13 and the locking base 14 in fig. 4 in the rotating process.
The end of the latch plate 12 far away from the locking part 13 is a handle part 14, the distance from the rotating shaft 9 to the locking part 13 on the latch plate 12 is smaller than the distance from the rotating shaft 9 to the handle part 14, and when the latch plate 12 is closed, the handle part 14 of the latch plate 12 is higher than the top edge of the latch base 11, wherein the top edge refers to the uppermost edge of the latch base 11.
If the shoelace 8 is to be loosened, the latch 12 will be opened in the direction of the arrow in fig. 5, and the state of fig. 4 will be passed during the opening process, since fig. 4 is the tightest state of the latch 12 against the shoelace 8, and if the state of fig. 3 (i.e. the shoelace 8 is completely loosened) is to be achieved, a sufficient force is required to break the latch 12 through a position perpendicular to the latch base 11, so that the state of fig. 3 can be returned.
Because the handle portion 14 of the latch tab 12 is higher than the top edge of the latch base 11, the handle portion 14 of the latch tab 12 can be more easily touched when a firefighter wants to break the latch tab 12 apart; because the distance between the rotating shaft 9 and the locking part 13 is smaller than the distance between the rotating shaft 9 and the handle part 14, the force arm from the handle part 14 of the locking piece 12 to the rotating shaft 9 is larger than the force arm from the rotating shaft 9 to the locking part 13, and according to the lever principle, if a firefighter wants to take off the boot, the locking piece 12 can be broken off more labor-effectively, so that the shoelace 8 is loosened.
Therefore, during rescue, the self-locking buckle 1 can ensure that the shoelace 8 is firmly clamped on the buckle base 11 and cannot be naturally loosened; and when the firefighter wants to take off the boot, the locking piece 12 can be broken off more labor-saving, so that the shoelace 8 is opened.
