Abstract
Description
Technical Field
[0001] This utility model relates to the field of fastener technology, specifically to a fastener with adjustable webbing length. Background Technology
[0002] Buckles, a common type of fastener, consist of a male buckle and a female buckle. They are fastened by inserting the tongue on the male buckle into the slot of the female buckle. They are widely used in products such as backpacks, seat belts, child seats, and clothing.
[0003] Currently, buckles lack anti-slip mechanisms. Typically, buckles use D-rings to adjust the webbing length. However, in scenarios such as backpacking, transportation, and equipment operation, continuous high-frequency vibrations can gradually loosen the webbing's locking position at bends, causing it to slowly slip. Furthermore, after prolonged use, wear on the anti-slip structure of the central crossbar and changes in the webbing material reduce friction between the crossbar and the webbing, making the webbing prone to shifting in position and affecting the buckle's effectiveness and stability. Therefore, this paper proposes an adjustable webbing buckle with an added auxiliary anti-slip mechanism. By increasing the buckle's friction, it effectively reduces webbing movement after prolonged use, improving the buckle's stability and reliability, and ultimately enhancing its performance. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides an adjustable webbing buckle, which effectively reduces the positional movement of the webbing after prolonged use by increasing the friction of the buckle, thereby improving the performance.
[0005] The technical solution adopted by this utility model to solve its technical problem is an adjustable webbing buckle, including a snap buckle, a D-ring buckle and an anti-slip component. The anti-slip component is sleeved on the outside of the D-ring buckle, and a protective component is sleeved on the outside of the snap buckle. The anti-slip component includes a sleeve, an anti-slip pad is adhered to the outer surface of the sleeve, the surface of the anti-slip pad is provided with anti-slip protrusions, and a retaining strip is provided on the inner side of the sleeve.
[0006] By adopting the above technical solution, the friction between the webbing and the D-ring is increased, making the webbing less prone to shifting.
[0007] Specifically, the protective component includes a U-shaped sleeve, and the U-shaped sleeve is slidably connected to a buckle, with a protrusion provided on the inner side of the U-shaped sleeve.
[0008] Specifically, a magnetic strip is fixedly installed inside the card strip, a crossbar is installed inside the D-ring buckle, and a card slot corresponding to the card strip is opened inside the crossbar.
[0009] Specifically, the snap fastener includes a female buckle and a male buckle. A sliding groove is formed on the surface of the female buckle, and a convex block is slidably connected to the sliding groove. A compression spring is installed on the top of the convex block in the sliding groove through a spring seat.
[0010] Specifically, a slot is formed in the female buckle, and a tongue is provided at the bottom of the male buckle.
[0011] Advantages of the present utility model: For the buckle for adjusting the length of a webbing provided by the present utility model, by providing a snap fastener, a D-ring, a sleeve, an anti-slip pad, anti-slip bumps and a strip, the anti-slip mechanism of the webbing is increased, the friction between the webbing and the D-ring is improved, and the position of the webbing is less likely to move, thereby improving the stability and reliability of the buckle.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] To improve performance by increasing the friction of the fasteners, thus effectively reducing the movement of the webbing after prolonged use, the following measures can be taken: Figure 1-3 As shown, the adjustable webbing buckle of this utility model includes a snap buckle 1, a D-ring buckle 2 and an anti-slip component 3. The anti-slip component 3 is sleeved around the D-ring buckle 2, and a protective component 4 is sleeved around the snap buckle 1. The anti-slip component 3 includes a sleeve 301, an anti-slip pad 302 is adhered to the outer surface of the sleeve 301, anti-slip protrusions 303 are provided on the surface of the anti-slip pad 302, and a clip 304 is provided on the inner side of the sleeve 301.
[0017] When in use, the anti-slip mechanism of the webbing is increased by the card sleeve 301, anti-slip pad 302 and anti-slip protrusions 303, which increases the friction between the webbing and the D-ring buckle, making the webbing position less likely to move.
[0018] Both the anti-slip mat 302 and the anti-slip bumps 303 are made of rubber.
[0019] To improve the stability and safety of fasteners, for example, such as Figure 1 , Figure 3 As shown, the present invention also includes a protective component 4 comprising a U-shaped sleeve 401, wherein the U-shaped sleeve 401 is slidably connected to a buckle 1, and a protrusion 402 is provided on the inner side of the U-shaped sleeve 401.
[0020] When in use, the U-shaped sleeve 401 and the protrusion 402 can increase the protective mechanism and form a protective structure around the female buckle 101, reducing the loosening of the buckle caused by accidental contact or squeezing.
[0021] For example, such as Figure 2 , 4 As shown, the present invention also includes a magnetic strip 305 fixedly disposed inside the card strip 304, a crossbar 201 disposed inside the D-ring buckle 2, and a card slot 202 corresponding to the card strip 304 being opened inside the crossbar 201.
[0022] When in use, the magnetic strip 305 facilitates the magnetic fixation of the crossbar 201, which is not only convenient for disassembly and assembly, but also inexpensive. It can be replaced after subsequent damage, reducing resource waste. The top and bottom of the slot 202 are provided with iron pieces corresponding to the magnetic strip 305.
[0023] For example, such as Figure 5 As shown, the present invention also includes the buckle 1, which includes a female buckle 101 and a male buckle 102. The surface of the female buckle 101 is provided with a sliding groove 103, and the protrusion 402 is slidably connected to the sliding groove 103. A compression spring 104 is installed in the sliding groove 103 at the top of the protrusion 402 through a spring seat.
[0024] In use, the female buckle 101, male buckle 102, slide groove 103 and compression spring 104 can be used in conjunction with the protective component 4 through guiding and limiting methods, and can also be automatically reset by pushing with elastic force.
[0025] For example, such as Figure 5 As shown, the present invention also includes a slot 105 provided in the female buckle 101 and a tongue 106 provided at the bottom of the male buckle 102.
[0026] In use, the female buckle 101 and the male buckle 102 are easily inserted and fixed by the slot 105 and the tongue 106. The male buckle 102 includes a resilient locking block.
[0027] In use, one end of the webbing is first passed through the D-ring buckle 2 and the male buckle 102 for fixation, and then the other end of the webbing is connected and fixed to the female buckle 101. By inserting the tongue 106 of the male buckle 102 into the slot 105 of the female buckle 101, the connection and fixation of the buckle can be completed by using the elastic locking block. In actual use, the anti-slip pad 302 and the anti-slip protrusion 303 can increase the friction between the webbing and the crossbar 201 of the D-ring buckle 2, improve the stability of the webbing, and make it less prone to slippage due to shaking and vibration, thereby ensuring the fixation of the length of the webbing. Furthermore, when opening the fastener, the U-shaped sleeve 401 needs to be pushed upward in advance so that the elastic locking blocks can be pushed out from both sides of the female buckle 101 to complete the separation of the fastener. This greatly improves the safety and stability of use, avoids loosening caused by external squeezing or accidental contact, and has a simple structure, low cost, and is more reasonable and reliable in use.
