Description

Technical Field

[0001] The present invention relates to the technical field of webbing adjustment structures, and particularly to a quick-release adjustment structure for webbing. Background Art

[0002] Webbing adjustment structures are widely used in many fields, such as belts, backpacks, gloves, ready-to-wear clothes, hats, etc. Common webbing disassembly and adjustment structures on the market, such as the structure disclosed in Chinese Utility Model (CN202020045024.X), that is, a protruding buckle piece is fixedly arranged in the middle of the notch for threading the webbing. Using this structure, when adjusting the length of the webbing, the end of the webbing that needs to be shortened is retracted into the notch, and then the end that needs to be lengthened is pulled out to complete the adjustment of the webbing. Another common webbing disassembly and adjustment structure, such as the structure disclosed in Chinese Utility Model (Application No.: 201920742505.3), that is, a transversely slidable adjusting rod is arranged in the mounting hole for threading the belt. After putting on the belt, the adjusting rod is forced to press the belt in the opposite direction of the external force. If the length of the belt needs to be adjusted, the adjusting rod needs to be toggled so that the belt is not pressed, thereby realizing the adjustment of the belt. The above two webbing adjustment structures are complex in operation, cannot be quickly disassembled and assembled, and the webbing is prone to sliding. Chinese Utility Model Patent (Application No.: CN201720662065.1) discloses a webbing adjustment structure, which combines a toothed pressing piece with a spring to fix the webbing passing through the webbing passage. Pressing the pressing piece releases the webbing, enabling the webbing to be easily adjusted in length. Releasing the pressing piece, the spring makes the pressing piece press the webbing tightly. This structure can achieve the quick disassembly, assembly and adjustment of the webbing, but the structure is relatively complex, and after long-term use, the spring force becomes weak and the webbing cannot be pressed tightly. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the prior art, the purpose of the present invention is to provide a webbing quick-release adjustment structure with simple structure, wide application, convenient adjustment, and quick disassembly and assembly.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A webbing quick-release adjustment structure includes a switch sliding piece, a webbing threading ring, and a base that are integrally formed respectively; the switch sliding piece is arranged above the webbing threading ring and is hinged to the base by the same pin shaft; the switch sliding piece is provided with a first hinged part, the first hinged part is provided with an oblate hinged hole, and the switch sliding piece is provided with a protruding part; an L-shaped groove matching with the protruding part is arranged on the inner side wall of the base.

[0006] Preferably, one end of the base is provided with a mounting through hole, and the inner shape of the mounting through hole matches the outer shapes of the switch sliding piece and the webbing threading ring; a switch push block is arranged on the upper part of the switch sliding piece.

[0007] Preferably, one end of the tape threading loop is provided with a first tape threading hole, the other end of the tape threading loop is a second hinge portion, and the outer side wall of the first tape threading hole away from the second hinge portion is provided with first anti-slip teeth.

[0008] Preferably, the first tape threading hole is of a rectangular structure.

[0009] Preferably, the first hinge portion protrudes downward; the second hinge portion is two horizontally arranged D-shaped structures that are symmetrical left and right, and the inner distance between the two horizontally arranged D-shaped structures is greater than the length of the first hinge portion; the left and right sides of the installation through hole are provided with first base hinge holes corresponding to the switch sliding piece and the tape threading loop.

[0010] Preferably, the inner side wall of the installation through hole away from the first base hinge hole is provided with second anti-slip teeth.

[0011] Preferably, a material-saving hole is formed in the middle of the switch sliding piece.

[0012] Preferably, the protruding portions are symmetrically arranged on the left and right sides of the switch sliding piece, and the L-shaped grooves are symmetrically arranged on the left and right inner sides of the base.

[0013] Preferably, the end of the base away from the installation through hole is provided with a second tape threading hole or a male snap fastener or a female snap fastener.

[0014] Preferably, the webbing quick-release adjustment structure further includes a webbing clamping member. A groove is provided at the end of the base away from the installation through hole, and second base hinge holes are formed on both sides of the groove. The webbing clamping member is hinged in the groove.

[0015] The present invention has the following advantages and effects compared with the prior art:

[0016] The main structure of the present invention is simple, with only three parts: a switch sliding piece, a tape threading loop, and a base. The parts are integrally formed, easy to assemble, and have low production costs.

[0017] The cooperation between the convex part and the L-shaped groove enables the switch sliding plate and the base to clamp the webbing on the threading loop, fixing the webbing. Therefore, the threading loop only needs to be set as a simple open-hole structure to allow the webbing to pass through smoothly. The webbing is threaded into the first threading hole. Rotate the switch sliding plate towards the mounting through-hole end of the base, and then gently push the switch sliding plate to clamp the webbing. At the same time, since the clamped webbing has a certain thickness, it can press the convex part upwards against the edge of the L-shaped groove, making it not easy to slide. The oval hinge hole of the switch sliding plate allows the switch sliding plate to slide back and forth, while restricting its sliding distance to prevent the convex part from sliding out of the L-shaped groove. When unfastening, only need to lift the tail of the webbing clamped by this webbing quick-release adjustment structure towards the end of the base away from the mounting through-hole, driving the switch sliding plate to slide towards the end of the base away from the mounting through-hole, thereby driving the convex part to slide out of the L-shaped groove and opening the switch sliding plate, so that the length of the webbing can be adjusted or the webbing can be taken out. Therefore, the disassembly, assembly, and length adjustment of the webbing can be quickly completed.

[0018] The setting of the mounting through-hole can prevent the situation where the switch sliding plate cannot be pressed down due to the excessive thickness of the webbing, making it difficult for the convex part to slide into the L-shaped groove, resulting in the inability to clamp the webbing. In addition, the switch sliding plate and the threading loop can be installed in the mounting through-hole of the base, making the product design flat. It can be used alone as a buckle or in combination with a buckle as the webbing connection end of the buckle, and is used in various products such as belts, backpacks, gloves, ready-to-wear clothes, hats, etc.

[0019] The horizontally arranged D-shaped structure of the second hinge part and the material-saving holes can both play a role in saving raw materials and reducing costs.

[0020] The setting of the first anti-slip teeth and the second anti-slip teeth can make the webbing less likely to slip when clamped. BRIEF DESCRIPTION OF THE DRAWINGS
