Description

Technical Field

[0001] This utility model relates to the field of clothing and accessories technology, and in particular to a novel belt buckle. Background Technology

[0002] A traditional belt consists of a belt body and a buckle. The buckle has a buckle body, a mounting component, and a buckle pin. The buckle body is a square frame formed by four rods. The first end of the buckle pin is movably connected to a rod on the first end of the buckle body. The second end of the buckle pin extends to the second end of the buckle body. The rod on the buckle body connected to the buckle pin is fixedly connected to the mounting component. The mounting component has a recessed groove on its side facing away from the buckle body for fixing the first end of the belt body. The second end of the belt body has a through hole. In application, the second end of the belt body extends into the hollow cavity of the buckle body, and the buckle pin passes through the through hole of the belt body, thus forming a closed loop, thereby achieving the waist-cinching effect of the belt.

[0003] However, the aforementioned belt buckle, with its fixed combination of buckle body, mounting parts, and buckle pin, can only present one fixed style, making it impossible to freely combine different belt buckles, resulting in poor versatility.Therefore, a double-sided belt buckle is provided, such as a universal double-sided belt buckle (2019106853392), which includes a buckle body, a mounting component, a buckle pin, and a belt loop. The buckle body is located on the left side of the mounting component. The first end of the buckle pin is rotatably mounted on the right side of the buckle body, and the second end of the buckle pin extends to the left to the left side of the buckle body. The right side of the mounting component has a mounting groove for the belt body to be inserted into. The belt loop has two opposing side bars and an upper crossbar integrally formed with the upper ends of the side bars. The lower ends of the side bars are correspondingly connected to the front and rear sides of the mounting component. The upper crossbar is located above the mounting component. The right side of the buckle body is provided with a mounting rod extending in the front-to-back direction. The width of the mounting rod in the left-to-right direction is smaller than that of the mounting rod. The width in the vertical direction is such that a through-cavity extending to the right and penetrating both the front and rear sides of the mounting component is provided on the left side of the mounting component. The vertical width of the through-cavity is greater than the vertical width of the mounting rod, and the vertical width of the through-cavity facing the mounting rod matches the horizontal width of the mounting rod. The mounting rod is inserted into the through-cavity through the left side opening and rotates within it. A receiving recess is provided on the left side of the mounting component at the first end of the buckle pin, communicating with the through-cavity and allowing the buckle pin to be accommodated and rotate within it. The two looped rods are respectively hinged to the front and rear side walls of the mounting component. Furthermore, the distance between the hinge point of the aforementioned side rod and the mounting component and the aforementioned upper horizontal rod is longer than the distance between the hinge point of the aforementioned side rod and the mounting component and the left side surface of the mounting component; the aforementioned mounting component has an upper plate and a lower plate formed at this through-cavity, and an elastic limiting member is provided at both the front and rear ends of the aforementioned through-cavity. The aforementioned elastic limiting member has an upper horizontal part extending along the left and right direction of the mounting component and a lower horizontal part located below the upper horizontal part and having a spacing that allows for relative compression and elastic deformation. The right side of the aforementioned upper horizontal part and the right side of the lower horizontal part are integrally connected by a U-shaped elbow. The upper horizontal part, the lower horizontal part, and the U-shaped elbow form a horizontally placed U-shaped component. A connecting piece is integrally formed between the right side of the aforementioned upper plate and the right side of the lower plate. The front side of the aforementioned connecting piece and The rear side is provided with U-shaped protrusions that are horizontally oriented in the left-right direction. The outer wall of the U-shaped protrusion and the cavity wall of the through cavity have a U-shaped channel that is adapted to the U-shaped structure of the elastic limiting member. The elastic limiting member is pressed and sleeved on the outside of the U-shaped protrusion and matched with the U-shaped channel. The left end of the upper horizontal part and the left end of the lower horizontal part are both located on the left side of the rod body installed in the through cavity. The left end of the upper horizontal part and the left end of the lower horizontal part are provided with limiting protrusions that are arranged opposite to each other. The distance between the two limiting protrusions is less than the width of the rod body in the left-right direction. The top surface of the upper limiting protrusion has an upper gap with the upper plate body, and the bottom surface of the lower limiting protrusion has a lower gap with the lower plate body.During application, since the width of the mounting rod in the left-right direction is smaller than its width in the top-bottom direction, the mounting rod should be held vertically during installation. The left-right width of the mounting rod should be aligned with the opening of the through-cavity. At this point, the mounting rod can be easily pushed in with a slight force to fit snugly into the through-cavity. Then, rotate the buckle to straighten it. Since the top-bottom width of the mounting rod is larger than the opening of the through-cavity, the mounting rod will not easily slip out, completing the buckle and installation. Installation of the component; accordingly, the mounting rod is erected again, and then pulled straight outward with a little force to disengage the mounting rod from the through cavity, thus separating the buckle from the mounting component; at the same time, due to the rotational cooperation between the side rod and the mounting component, the strap can flip downward or upward around the hinge point, and the distance between the hinge point of the side rod and the mounting component and the upper horizontal bar is longer than the distance between the hinge point of the side rod and the mounting component and the left side of the mounting component, so the strap can flip downward to the bottom of the buckle, realizing the double-sided use of the belt buckle.

[0004] This universal double-sided belt buckle is installed by keeping the mounting rod vertical and rotating the buckle body to make it horizontal, thus installing the buckle body and the mounting piece. However, when the user is operating the belt through the buckle body, they usually pull the buckle body outward along the mounting piece, which can easily cause the mounting rod to change from a horizontal to a vertical position. The mounting rod can then easily slip out of the through cavity, leading to operator error and separation of the buckle body from the mounting piece, making it inconvenient to use.

[0005] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content

At this time, the spherical ball is inserted into the first front positioning groove 601 under the action of the compression spring, realizing the positioning engagement of the positioning part and the guide sliding part. Even after rotating 180 degrees, the positioning strip 32 can still slide from front to back into the strip groove through the insertion port. At this time, the spherical ball is inserted into the first rear positioning groove 602 under the action of the compression spring, realizing the positioning engagement of the positioning part and the guide sliding part. This allows the belt buckle to be used on both sides, and the buckle body and the mounting part can be freely disassembled and assembled, making it more flexible to use.

[0035] In this novel belt buckle, the upper plate 11 and lower plate 12 are opened relative to each other. One end of the belt body extends between the upper plate 11 and lower plate 12, pressing them together so that the front positioning protrusion and the rear positioning protrusion are arranged side by side. Then, the front positioning protrusion and the rear positioning protrusion are slid into the strip groove from front to back through the insertion port. The front positioning protrusion and the rear positioning protrusion are embedded in the strip groove, and with the positioning cooperation of the positioning bead 4 and the positioning groove structure, the front positioning protrusion... The protrusion and the rear positioning protrusion can be confined within the strip groove to achieve the positioning of the positioning part. To remove the positioning strip from the strip groove, simply hold the mounting part 1 and apply slight force from back to front. Under the action of the compression spring, the spherical body can be dislodged from the positioning groove structure. Compared with the prior art, which requires back-and-forth movement of the mounting part to separate the buckle and the mounting part, the user is less likely to make mistakes during the operation of the belt passing through the buckle, which would lead to the separation of the buckle and the mounting part. The operation is more convenient.

[0036] This invention relates to a novel belt buckle, specifically Embodiment Two. The difference between Embodiment Two and Embodiment One lies in the placement of the positioning structure; for example... Figure 4As shown, the positioning structure has a positioning groove 700 and a component 1 that can be inserted into the positioning groove 700 and is mounted with it. The positioning bead structure can still be engaged in the positioning groove 700 even after a 180-degree rotation; specifically, the positioning strip 32 is a cylindrical structure, and the corresponding strip groove is also a cylindrical structure. The inner sidewall of the front end of the strip groove 100 is recessed outward to form the aforementioned positioning groove 700. The outer sidewall of the front end of the positioning strip 32 is recessed to form a first front-mounting groove opposite to the positioning groove. The first front-mounting groove is located on the front positioning protrusion. The first front-mounting groove extends along the circumferential direction of the positioning strip 32 and has a non-closed annular structure. The positioning groove can be opened in the annular space that falls into the first mounting groove. A first lower bead 51 that can be engaged in the positioning groove 700 is provided in the first front-mounting groove at the position corresponding to the positioning groove. The outer sidewall of the upper end of the positioning strip 32 is recessed to form a first rear-mounting groove that can be engaged with the positioning groove after the positioning strip 32 rotates 180 degrees. The first rear-mounting groove extends along the circumferential direction of the positioning strip 32 and has a non-closed annular structure. A rear-mounting groove that extends along the circumferential direction of the positioning strip 32 at the position corresponding to the positioning groove is provided in the first rear-mounting groove. A 180-degree rotation allows the first upper bead 52 to be inserted into the positioning groove. The first lower bead 51 and the first upper bead 52 constitute the above-mentioned positioning bead structure. The specific structure of the first lower bead 51 and the first upper bead 52 and their installation method with the connector are similar to the installation method of the positioning bead and the connector in Embodiment 1, and will not be described in detail here. In application, the positioning strip 32 is embedded into the strip groove from front to back. If the positioning groove is set on the lower left inner side wall of the strip groove, the positioning groove extends in the left and right direction. The first lower bead 51 and the first upper bead 52 are respectively set on the bottom of the left inner groove of the first front insertion groove and the bottom of the left inner groove of the first rear insertion groove. The left end of the first lower bead 51 and the first upper bead 52 both extend out of the left side of the positioning strip 32. When the positioning strip extends into the positioning groove from front to back, the first lower bead 51 can also enter the positioning groove under the action of the compression spring. Moreover, after the positioning strip 32 is rotated 180 degrees, the first upper bead 52 can also extend into the positioning groove 700 from front to back, so as to realize the positioning of the positioning strip 32. Similarly, if the positioning groove is set on the inner sidewall of the lower end of the strip groove, the first lower bead 51 is set on the inner sidewall of the first front insertion groove, and the first upper bead 52 is set on the inner sidewall of the first rear insertion groove. The top surface of the first lower bead 51 extends out of the top surface of the lower end of the positioning strip 32 and can extend into the positioning groove 700. The bottom surface of the first upper bead 52 extends out of the bottom surface of the upper end of the positioning strip 32 and can still extend into the positioning groove 700 after the positioning strip 32 is rotated 180 degrees. If the positioning groove is set on the inner sidewall of the lower end of the strip groove, the bottom surface of the first lower bead 51 extends out of the bottom surface of the lower end of the positioning strip 32 and can extend into the positioning groove. The top surface of the first upper bead 52 extends out of the top surface of the upper end of the positioning strip 32 and can still extend into the positioning groove after the positioning strip 32 is rotated 180 degrees.

[0037] This invention relates to a novel belt buckle, as shown in Embodiment 3. Figures 5-6 As shown, the difference between this embodiment and Embodiment 1 lies in the specific location of the positioning structure and the connection method between the mounting body 2 and the connecting body 3. Specifically, the positioning strip 32 is a square column structure extending in the front-back direction, and the corresponding strip groove is a hollow square column structure. The inner wall of the rear end of the strip groove 100 is recessed with a second mounting groove 502 facing upward, downward, or to the left.
