Description

Technical Field

[0001] This utility model relates to the field of fixing buckle devices, specifically a telescopic webbing fixing buckle. Background Technology

[0002] Fasteners, such as aluminum buckles, are accessories used on retractable webbing in products such as backpacks and shoes. They are mainly used to adjust and lock the length of the webbing to prevent it from slipping freely.

[0003] For example, Chinese Utility Model Patent No. ZL201921858584.0 discloses an aluminum buckle and an aluminum buckle assembly. The aluminum buckle includes a first sleeve and a press buckle. The first sleeve is a hollow cylindrical structure. The press buckle is located at the end of the first sleeve away from the bottom plate. The press buckle is a columnar structure, and one end of the press buckle is slidably connected to the inner wall of the first sleeve. The press buckle is provided with a second rope hole corresponding to the first rope hole. In this utility model, when the press buckle is pressed, the second rope hole is exposed, which facilitates the insertion of a drawstring and allows for adjustment of the drawstring's position to achieve the purpose of adjusting the tightness of the drawstring. After the drawstring is installed, the press buckle is released, and the first elastic element elastically resets the press buckle, causing it to slide away from the first sleeve. The first and second rope holes press and fix the drawstring. Furthermore, a limiting protrusion is provided at the opening of one end of the first sleeve to ensure that the press buckle will not pop out of the first sleeve, effectively improving the stability of the equipment.

[0004] Although the aforementioned patents improve the stability of the equipment, their complex structure makes them inconvenient for later assembly and use. Utility Model Content

[0005] The purpose of this utility model is to provide a telescopic webbing fixing buckle, which has an anti-slip limiting effect through a first mounting hole, a second mounting hole and a matching anti-slip boss, and has a simple structure, making it easy to assemble and use later.

[0006] This utility model is implemented as follows: a telescopic webbing fixing buckle includes a fixing buckle body, one end of which extends upward at an angle to form a bent portion. The fixing buckle body has a first mounting hole, a second mounting hole, and a third mounting hole sequentially formed from front to back. The first mounting hole and the second mounting hole are telescopic webbing mounting holes, and the telescopic webbing can slide along the first mounting hole and the second mounting hole in the forward or reverse direction to adjust its length. The third mounting hole is a fixing webbing mounting hole. The first mounting hole is located on the bent portion. An anti-slip protrusion is provided on one side of the first mounting hole. The anti-slip protrusion extends at an angle towards the middle of the first mounting hole, forming a multi-directional bend for the telescopic webbing that passes through, and forming a limit or anti-slip for the forward and reverse sliding of the telescopic webbing.

[0007] Furthermore, the angle between the upward tilt of the bent portion and the ground is 10-60 degrees.

[0008] Furthermore, the first mounting hole, the second mounting hole, and the third mounting hole are arranged at equal intervals, and all three sets of mounting holes are vertically arranged along the width direction of the fixing buckle body.

[0009] Furthermore, the anti-slip protrusion is arranged along the vertical length direction of the first mounting hole, and the length of the anti-slip protrusion is less than or equal to the vertical length of the first mounting hole.

[0010] Furthermore, the silicone sealant has an annular structure, and the anti-slip protrusion is located near the front end of the bent portion and adjacent to the first mounting hole.

[0011] Furthermore, the main body of the fixing buckle is made of metal or plastic.

[0012] Furthermore, the anti-slip protrusion and the fixing buckle body are integrally die-cast or integrally injection molded.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0022] like Figures 1-3As shown, a retractable webbing fastener includes a fastener body 1, with its front end extending upwards to form a bent portion 10. The fastener body 1 has a first mounting hole 11, a second mounting hole 12, and a third mounting hole 13 sequentially formed from front to back. The first mounting hole 11 and the second mounting hole 12 are mounting holes for the retractable webbing, allowing the retractable webbing to slide forward or backward along the first mounting hole 11 and the second mounting hole 12 to adjust the length of the retractable webbing. The third mounting hole 13 is a webbing fixing hole for securing the webbing. After passing through the third mounting hole 13, both ends are fixed to the bag with stitching. The first mounting hole 11 is located on the bending part 10. Since the bending part 10 is not horizontal, it forms a certain angle with the rear end, so that the first mounting hole 11 and the second mounting hole 12 are arranged in a V-shape. When the two ends of the elastic webbing pass through the first mounting hole 11 and the second mounting hole 12 respectively, the first bending effect is formed. An anti-slip protrusion 14 is provided on one side of the first mounting hole 11. The anti-slip protrusion 14 extends and protrudes at an incline towards the middle of the first mounting hole 11. When the elastic webbing is extended... When the two ends of the telescopic webbing are stretched horizontally in the same direction through the first mounting hole 11 and the second mounting hole 12, the anti-slip boss 14 forms a second bend on the telescopic webbing passing through the first mounting hole 11, creating a multi-directional bending effect on the telescopic webbing and limiting or preventing the telescopic webbing from sliding in both directions. Users can adjust the length of the telescopic webbing by pulling the end of the telescopic webbing passing through the first mounting hole 11. Furthermore, the telescopic webbing generates a certain damping force when sliding, and the telescopic webbing passing through the second mounting hole 12... Due to the multi-directional bending effect of the telescopic webbing, when both ends of the telescopic webbing are forward of the bending part 10, the telescopic webbing is in a limited locking state and cannot be length adjusted. That is, the telescopic webbing located in the second mounting hole 12 cannot be pulled forward of the bending part 10. When the telescopic webbing located at one end in the second mounting hole 12 is opposite to the other end of the telescopic webbing passing through the first mounting hole 11, the length can be adjusted by pulling the telescopic webbing located in the second mounting hole 12. The telescopic webbing has a certain damping force when sliding.

[0023] In this way, by opening the first mounting hole 11, the second mounting hole 12 and the anti-slip protrusion 14 at the first mounting hole 11 on the main body of the fixed buckle, a multi-directional bending effect is formed on the telescopic webbing, and an anti-slip limit is formed for the telescopic webbing that slides in the forward or reverse direction, thereby improving the stability of the telescopic webbing after adjustment and preventing it from sliding at will.

[0024] like Figure 1-3As shown, the upward tilt angle of the bending portion 10 is 10-60 degrees with the ground, so that the first mounting hole 11 and the second mounting hole 12 are on different horizontal planes. This creates a bending effect on the telescopic webbing passing through the first mounting hole 11 and the second mounting hole 12, and also increases the damping force for the telescopic webbing sliding through the first mounting hole 11 and the second mounting hole 12. The first mounting hole 11, the second mounting hole 12 and the third mounting hole 13 are arranged at equal intervals, and all three sets of mounting holes are vertical along the width direction of the fixing buckle body 1. The three sets of mounting holes are rectangular holes. The anti-slip protrusion 14 is set along the vertical length of the first mounting hole 11. The length of the anti-slip protrusion 14 is less than or equal to the vertical length of the first mounting hole 11. The anti-slip protrusion 14 is located near the front end of the bending part 10 and adjacent to the first mounting hole 11. The fixing buckle body 1 is made of metal or plastic. The anti-slip protrusion 14 and the fixing buckle body 1 are integrally die-cast or integrally injection molded. In this embodiment, the fixing buckle body 1 is made of metal, such as stainless steel or aluminum alloy.

[0025] Thus, the overall structure of this utility model is simple, easy to assemble and use, and very practical.

[0026] In summary, this utility model, by opening a first mounting hole 11 and a second mounting hole 12 on the fixing buckle body and setting an anti-slip protrusion 14 at the first mounting hole 11, forms a multi-directional bending effect on the telescopic webbing and provides anti-slip limit for the telescopic webbing sliding in the forward or reverse direction, thereby improving the stability of the telescopic webbing after adjustment and preventing it from sliding at will. Moreover, the overall structure is simple and easy to assemble and use later, making it very practical.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
