[0019] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be an element centered thereon. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may also be an element centered thereon. When the number of an element is referred to as having "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings:

[0023] like Figure 1-3As shown, in this embodiment, a new type of left-right rotating lock buckle is provided, including an annular buckle body 1, the buckle body 1 is provided with an opening, the buckle body 1 is used to pull and buckle the rope, and the opening is provided for the rope to enter and exit, and change clothes. One end of the buckle body 1 is hinged with a movable pin 3, and a stress spring 10 is provided at the hinge between the movable pin 3 and the buckle body 1. The movable pin 3 is used to prevent the movable pin 3 from being detached from the buckle body 1. The stress spring 10 is inserted into the movable pin 3. The stress spring 10 is always enabled outward so that the movable pin 3 can be pushed outward all the time to ensure that the other end of the movable pin 3 is continuously in contact with the buckle body 1. That is, when it is necessary to replace the rope or pull out the rope, it is necessary to overcome the force of the stress spring 10 before the movable pin 3 can be pressed inward. At the same time, in order to prevent the movable pin 3 from being opened by mistake, a limit piece is sleeved on the movable pin 3. A torsion spring 9 is fixedly arranged coaxially inside the movable pin 3. The torsion spring 9 is provided with a fixed end extending outward, which is fixedly connected to the limit piece, that is, the torsion spring 9 is used to limit the position of the limit piece on the movable pin 3. If the movable pin 3 is to be opened, the stress of the torsion spring 9 needs to be overcome to rotate the limit piece 2 open (which will be further mentioned below) so that it no longer covers the upper part of the limit abutment groove 7. At this time, the movable pin 3 is not restricted and can be pressed downward to open the opening of the buckle body 1.

[0024] In this embodiment, a limited abutment groove 7 is defined at one end of the movable pin 3 that abuts the buckle body 1. The movable pin 3 abuts the buckle body 1 through the limited abutment groove 7. The limiting member is provided with a forward-extending blocking piece 4, which covers the limited abutment groove 7. When the movable pin 3 is opened, the movable pin 3 moves vertically toward the inside of the buckle body 1, that is, the limited abutment groove 7 is disengaged vertically toward the inside of the buckle body 1. Thus, the buckle body 1 is opened.

[0025] In this embodiment, a pair of through grooves 11 are provided at one end of the limiter near the hinge between the movable pin 3 and the buckle body 1. The through grooves 11 are symmetrically arranged on both sides of the limiter. When the movable pin 3 moves downward (when it is flipped into the buckle), part of the end of the buckle (the end of the opening) will abut against it.

[0026] To further explain, the baffle 4 is provided with a top sheet 5 extending integrally to both sides, the top sheet 5 is bent and formed in contact with the outer side of the movable pin 3, and the movable pin 3 is fixedly provided with a positioning block 6. The positioning block 6 is located between a pair of top sheets 5, and the symmetry axis of the top sheet 5 and the symmetry axis of the pair of through grooves 11 are collinear. That is to say, when the top sheet 5 abuts against the positioning block 6, there must be a through groove 11 facing upward and a through groove 11 facing downward to ensure that the movable pin 3 and the limit sheet 2 can move downward smoothly. Because after the limit sheet 2 is rotated into place, the top sheet 5 will limit the limit sheet 2 from excessive rotation, and the pair of through grooves 11 will be coplanar with the direction of rotation of the movable pin 3, thereby smoothly flipping over, because when flipping, the buckle 5 is buckled. The end portion of the body 1 (specifically, the hinged portion between the movable pin 3 and the buckle body 1) will abut against the through groove 11 of the limiting plate 2. Therefore, after flipping, the limiting plate 2 will remain flipped, so that even if the limiting plate 2 is released, it will not rotate and reset. When the movable pin 3 is released, the movable pin 3 will reset upwards all the time. When the end of the buckle body 1 is separated from the through groove 11, the limiting plate 2 will reset under the action of the torsion spring 9. At this time, a sequential reset will be triggered. That is, after the user releases the movable pin 3, the movable pin 3 will reset upwards due to the stress spring 10. After one end of the buckle body 1 is mounted in the limiting abutment groove 7, the limiting plate 2 will rotate and reset, and the blocking plate 4 will reset to rotate above the limiting abutment groove 7. This technical feature is also one of the reasons why the present invention can be operated with one hand. The surface of the limiting plate 2 is provided with a circle of friction lines, and the friction lines are arranged on the limiting plate 2.

[0027] Taking into account the user's handedness, the limit plate 2 of the present invention is bidirectionally rotatable to enable one-handed operation. This is why the through slot 11 and the top plate 5 are paired, so that the limit plate 2 no longer limits the movable pin 3 whether it rotates counterclockwise or clockwise; that is, the blocking plate 4 no longer covers the limit abutment slot 7.

[0028] In this embodiment, a slot 8 extends inward along the middle of the limiting plate 2, and the fixed end of the torsion spring 9 is clipped into the slot 8 and fixedly connected to the limiting plate 2. This clipping method facilitates disassembly and assembly. Alternatively, the fixed end of the torsion spring 9 can be directly welded to the limiting plate 2, but this is not conducive to disassembly and replacement.

[0029] The technical features of the above-described embodiments can be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there are no contradictions in the combination of these technical features, they should be considered to be within the scope of this specification. For those skilled in the art, without departing from the concept of the utility model, they can also make several variations and improvements, which fall within the scope of protection of the utility model. Therefore, the scope of protection of this utility model patent shall be based on the appended claims.
