[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] It will be understood that the terms "first," "second," etc. used herein may be used to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element.

[0028] In one embodiment, a rope buckle is proposed, including a shell 100, a push block 200 and an elastic member 300. The shell 100 is slidably connected to the push block 200, and the elastic member 300 is arranged between the two. A pressure block 210 is provided on the push block 200, and a guide rope space is formed between the pressure block 210 and the inner wall of the shell 100. A first clamping block 220 is also provided on the push block 200, a groove 110 is provided on the shell 100, and a second clamping block 120 is provided on the groove 110. The first clamping block 220 is restricted in the groove 110 by the second clamping block 120.

[0029] In this embodiment, the cord lock is suitable for strip-shaped objects that can be assembled with fasteners, such as ropes, straps, or connecting wires. The housing 100 is hollow and contains the cord 400. The push block 200 and the housing 100 can only slide relative to each other in one direction. An elastic member 300 is disposed between the two to provide a compressive force; the elastic member 300 can be a coil spring, gas spring, or rubber spring. In this embodiment, a first clamping block 220 is provided on the push block 200, and a groove 110 and a second clamping block 120 are provided on the housing 100. This confines the first clamping block 220 within the groove 110, preventing the push block 200 from being pushed out by the elastic member 300 and improving installation convenience.

[0030] In an optimized solution of this embodiment, the pressing block 210 is provided with a plurality of limiting plates 230, which form a space for accommodating the elastic member 300. The number of limiting plates 230 is at least two, and the purpose is to construct an accommodating space on the side of the pressing block 210 for placing the elastic member 300 and prevent the elastic member 300 from shifting.

[0031] In an optimized solution of this embodiment, the elastic member 300 is a spring, a first protrusion 240 is provided between the plurality of limit plates 230, a second protrusion 130 is provided inside the housing 100, and the ends of the elastic member 300 are respectively inserted into the first protrusion 240 and the second protrusion 130. The spring is locked into the first protrusion 240 and the second protrusion 130 to prevent displacement.

[0032] In an optimized solution of this embodiment, the housing 100 is provided with a sliding groove 140, the push block 200 is provided with a connecting block 250, and the pressing block 210 is provided on the connecting block 250. The connecting block 250 is slidably connected to the sliding groove 140. The connecting block 250 is smaller than the pressing block 210. After installation, the pressing block 210 is located inside the housing 100, so that the push block 200 can only reciprocate in the direction restricted by the sliding groove 140.

[0033] In an optimized solution of this embodiment, the pressing block 210 is provided with a plurality of reverse teeth 260 on the side close to the rope 400. The direction of the reverse teeth 260 is opposite to the direction of pulling out the rope 400, and is used to increase the bite force between the pressing block 210 and the inner wall of the housing 100.

[0034] In an optimized solution of this embodiment, the first engaging blocks 220 are provided on both sides of the connecting block 250, and the grooves 110 are provided on both sides of the sliding slot 140. Both the second engaging block 120 and the first engaging block 220 are provided with inclined surfaces for insertion. This arrangement facilitates installation: by pushing the pushing block 200 in the direction of the sliding slot 140, the first engaging block 220 and the second protrusion 130 move along the inclined surfaces, ultimately achieving insertion.

[0035] In an optimized solution of this embodiment, an anti-slip protrusion 270 is provided on the pushing surface of the pushing block 200 .

[0036] In an optimized solution of this embodiment, two rope holes 150 are provided on the housing 100, and two rope guiding spaces are formed between the pressing block 210 and the inner wall of the housing 100, and the rope guiding spaces are connected to the rope holes 150. The buckle can clamp the rope 400 through the U-shaped structure, making it more secure.

[0037] The installation method of the structure combining all the above features is as follows: the elastic member 300 is inserted into the first protrusion 240, and the push block 200 is slid into the housing 100, so that the connecting block 250 slides relative to the sliding groove 140, and the first clamping block 220 moves relative to the second protrusion 130 along the inclined surface, and is clamped and confined in the groove 110.

[0038] The working principle of the structure combining all the above features is as follows: after installation, push the push block 200 to squeeze the spring, pass both ends of the rope 400 through the rope hole 150 and the rope guide space, then release the push block 200, and the reverse teeth 260 on the pressure block 210 bite the rope 400 to achieve the tightening effect.

[0039] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
