Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt buckles, and more particularly to a detachable belt buckle for fixing belts. Background Technology
[0002] Traditional belt buckles typically consist of a buckle body and a latch. The buckle body has holes on both sides, and the latch is hinged into these holes via a rotating shaft. However, this type of belt buckle has the following drawbacks:
[0003] 1. Traditional belts are usually fixed to the buckle with strong adhesive only. The belt is easy to slip due to force and is difficult to replace. The buckle structure is complicated and the operation is cumbersome when replacing the belt or adjusting the belt length.
[0004] 2. Severe wear of the fixing teeth: After long-term use, the fixing teeth are prone to wear, which reduces the locking effect between the belt and the belt buckle. At this time, the entire belt needs to be replaced, which is costly.
[0005] Therefore, there is an urgent need to design a belt buckle that is structurally sound, easy to operate, and securely fixed to solve the above problems. Utility Model Content
[0006] This invention addresses the shortcomings of existing technologies by providing a detachable belt buckle for securing belts.
[0007] The present invention solves the above-mentioned technical problems through the following technical solution:
[0008] A detachable belt buckle includes a buckle body and a matching cover plate. The buckle body includes a receiving portion and a snap-fit portion on both sides. The bottom of the receiving portion has an open protrusion for installing the matching cover plate. The matching cover plate has a matching protrusion that mates with the open protrusion. The matching protrusion engages within the opening of the open protrusion, allowing the matching cover plate to be detachably fixed to the receiving portion. The outer end of the matching cover plate in the x-axis direction has continuous fixing teeth extending along the y-axis direction. The fixed end of the belt extends into the receiving portion along the x-axis direction and is engaged by the fixing teeth, locked by the engagement between the matching cover plate and the receiving portion. This design enables quick installation and removal of the belt and buckle. Through the engaging structure of the matching protrusion and the open protrusion, the fixing teeth and the receiving portion work together to increase the clamping force at the belt end, allowing the belt end to be fixed by the detachable matching cover plate. This facilitates maintenance and replacement of belts of different lengths and styles. When the fixing teeth wear severely after long-term use, only the matching cover plate needs to be replaced, reducing maintenance costs.
[0009] Preferably, the accommodating part has sidewalls on both sides in the y-axis direction to limit the belt.
[0010] Preferably, a partition extending in the z-axis direction is provided between the receiving part and the snap-fit part, so that the receiving part and the snap-fit part form independent chambers respectively. This limits the length of the fixed end of the belt entering the receiving part, preventing excessive length from causing the belt end to twist and affecting the closing of the matching cover plate.
[0011] Preferably, it also includes a buckle body, which is inserted into the buckle portion and engages with the buckle portion.
[0012] Preferably, the buckle body has at least two cord-threading holes extending along the y-axis and penetrating the buckle body along the z-axis on the side away from the buckle body, for the movable end of the belt to pass through and be secured. Grooves are provided on both sides of the buckle body along the y-axis for engaging with the buckle body. The length of the belt is adjusted in real time by the length of the portion of the belt's movable end that passes through the cord-threading holes.
[0013] Preferably, the belt buckle body also includes a rotating shaft on both sides of the buckle part in the y-axis direction, and a pawl is installed on the rotating shaft. The pawl on both sides can rotate around the pawl as an axis, and the pawl locks into the groove to achieve fixation.
[0014] Preferably, both sides of the latches have a pressing part and a claw part, with the rotating shaft located between the pressing part and the claw part. The pressing part protrudes from the left and right sides of the buckle body, and the claw parts are arranged facing each other. The latches on both sides are connected to a return spring that drives the claw parts to swing inward. The exposed pressing part facilitates user operation; the facing claw parts enhance the clamping force; and the return spring enables automatic reset, improving ease of use.
[0015] Preferably, the return spring is a torsion spring mounted on the rotating shaft and connected at its end to the chuck. The torsion spring has a simple structure and is easy to install. The torsion spring connects to the chuck, providing a stable restoring force and ensuring that the chuck quickly clamps the fastener after release.
[0016] Preferably, the snap-fit part is provided with a main cover plate, which cooperates with the snap-fit part to form a cavity into which the snap-fit body extends. The cavity structure protects the internal snap-fit components and prevents dust from entering.
[0017] Preferably, the belt buckle body is made of a single piece of molded plastic. Plastic material reduces production costs, facilitates assembly, and makes the belt buckle more aesthetically pleasing.
[0018] This utility model, by adopting the above technical solution, has significant technical effects:
[0019] This invention solves the problems of insecure fastening, inconvenient replacement, and unstable structure of existing belt buckles, providing a detachable, easily replaceable, and reliably fastening belt buckle. It features concealed fastening at the belt end and is very convenient for belt replacement, facilitating quick assembly and disassembly. Because the connections between the belt buckle and the belt, and between the various components of the belt buckle, are not fixed but rather secured using interlocking or snap-fit structures, each component can be replaced independently. Repairing or replacing belt buckle components, or changing to belts of different lengths or styles, is very convenient. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0026] Example 1
[0027] A detachable belt buckle for securing a belt, such as Figure 1-4 As shown, the belt buckle includes a belt buckle body 1 and a matching cover plate 2. The belt buckle body 1 includes a receiving portion 11 and a buckling portion 12 provided on both sides. The bottom of the receiving portion 11 is provided with an opening protrusion 13 for installing the matching cover plate 2. The matching cover plate 2 has a matching protrusion 21 that cooperates with the opening protrusion 13. The matching protrusion 21 is engaged in the opening of the opening protrusion 13 so that the matching cover plate 2 is detachably fixed to the receiving portion 11. The outer end of the matching cover plate 2 in the x-axis direction is provided with a continuous fixing tooth 22 extending along the y-axis direction. The fixed end of the belt extends into the receiving portion 11 along the x-axis direction and is engaged by the fixing tooth 22 and locked by the cooperation between the matching cover plate 2 and the receiving portion 11.
[0028] The accommodating part 11 has sidewalls 14 on both sides in the y-axis direction to limit the belt.
[0029] A partition 16 extending in the z-axis direction is provided between the accommodating part 11 and the snap-fit part 12, so that the accommodating part 11 and the snap-fit part 12 each form an independent chamber.
[0030] It also includes a buckle body 3, which is inserted into the buckle part 12 and engages with the buckle part 12.
[0031] The buckle body 3 has at least two rope holes 31 extending along the y-axis and penetrating through the buckle body 3 in the z-axis direction on the side away from the buckle body 1, for the movable end of the belt to be wound through and locked. The buckle body 3 has grooves 32 on both sides in the y-axis direction for cooperating with the buckle body 1.
[0032] The belt buckle body 1 also includes a rotating shaft 15 on both sides of the buckle part 12 in the y-axis direction. The rotating shaft 15 is equipped with a claw 5. The claws 5 on both sides can rotate around the claw 5 as the axis. The claws 5 lock into the groove 32 to achieve fixation.
[0033] Each of the two side claws 5 has a pressing part 51 and a claw part 52. The rotating shaft 15 is located between the pressing part 51 and the claw part 52. The pressing part 51 protrudes from the left and right sides of the buckle body 1, and the claw parts 52 are arranged facing each other. The two side claws 5 are connected to a return spring that drives its claw parts 52 to swing inward. The return spring is not shown in the figure. The return spring can be a torsion spring set on the rotating shaft 15 and connected to the claw 5 at its end. The return spring can also be a spring connected to a certain part of the buckle body 1 and the claw 5. When the user presses the pressing part 51 of the claw 5, the claw parts 52 move in opposite directions, disengaging from the groove 32 of the buckle body 3, so that the buckle body 3 can be separated from the two ends of the belt of the buckle body 1. After the pressing part 51 of the claw 5 is stopped, the claw parts 52 rotate in opposite directions under the elastic force of the return spring.
[0034] When the buckle body 3 enters the belt buckle body 1, the claw 52 is opened by the buckle body 3, and the claws 52 of the latch 5 move in opposite directions. The return spring accumulates elastic potential energy. When it reaches the end, the elastic potential energy of the return spring is released, and the claw 52 of the latch 5 rotates and engages with the groove 32 of the buckle body 3, thus fixing the buckle body 3 to the belt buckle body 1. The length of the belt is adjusted in real time by the length of the part of the belt that passes through the rope hole 31 around the movable end of the belt.
[0035] The buckle part 12 is provided with a main cover plate 6, which cooperates with the buckle part 12 to form a cavity into which the buckle body 3 extends. The buckle body 1 is a one-piece molded plastic buckle body. The connection between the buckle body 1 and the main cover plate and the matching cover plate 2 is a snap-fit structure, which does not require other connection structures that rely on welding. It can be made of one-piece molded plastic material, which can reduce the cost of the buckle and make it more adaptable in appearance.
[0036] Assembly process when replacing or installing belts:
[0037] 1. Insert the fixed end of the belt into the receiving part;
[0038] 2. Cover the mating cover plate, so that its mating protrusion engages with the opening protrusion, and the fixing teeth on the mating cover plate bite the fixing end of the belt to achieve fixation;
[0039] 3. The fastener is inserted into the latching part, and the claws on both sides lock the fastener in place. It can be quickly opened by pressing the pressing part.
