[0022] As shown in the drawings: a symmetrical roller waistband buckle, comprising a shell 2, a roller 4 and a connecting part, the shell 2 is a symmetrical structure with thick middle and thin ends, the shell 2 is provided with a sliding groove 10 penetrating from top to bottom, the roller 4 is arranged in the sliding groove 10, the inner side of the right end of the shell 2 is provided with a connecting part, the connecting part comprises a pressing plate 6 and a bolt 7, the end of the waistband is fixed on the shell 2 through the cooperation of the bolt 7 and the pressing plate 6; preferably, the shell 2 adopts a symmetrical design to prevent the shell 2 from being thick on one side and thin on the other side, the end of the waistband is fixed on the shell 2 through the cooperation of the pressing plate 6 and the bolt 7, and the symmetrical feature of the shell 2 is combined, thereby avoiding the situation that the end of the shell 2 connected with the belt 1 is thick, and improving the use comfort of the belt 1 buckle.

[0023] In the embodiment, the sliding groove 10 is arranged at the left end of the shell 2 and is arranged in parallel with the inner side line of the shell 2. The parallel arrangement of the sliding groove 10 and the inner side line of the shell 2 effectively avoids that the roller 4 is too tight with the belt 1 after the belt 1 is stressed, affects the convenience of use of the belt 1 buckle, reduces the difficulty of pulling open with great force when the roller 4 is loosened, and ensures the effect of the roller 4 on the belt 1.

[0024] In the embodiment, the inner side of the shell 2 is provided with a reinforcing rod; the reinforcing rod is arranged to improve the structural strength of the shell 2. Preferably, the reinforcing plate comprises an end limiting rod 3 and a middle connecting rod 5, and the end limiting rod 3 is arranged at the left end of the shell 2. The arrangement of the limiting rod 3 and the connecting rod 5 facilitates the guiding and restraining effect on the belt 1, enhances the structural strength of the shell 2, increases the contact area between the shell 2 and the human body, reduces the compression of the shell 2 on the body, and improves the use comfort.

[0025] In the embodiment, the surface of the roller 4 is a rough surface, and the rough surface comprises knurling, strip pattern or wave pattern. The rough surface design of the roller 4 improves the friction between the roller 4 and the belt 1, and avoids that the belt 1 is too smooth to be buckled by the belt buckle.

[0026] In the embodiment, the connecting part is provided with a limiting tooth 8, and the limiting tooth 8 is welded and fixed on the shell 2. The connecting strength between the end of the belt 1 and the belt buckle is improved.

[0027] In the embodiment, the pressing plate 6 is an arc-shaped pressing plate 6, the limiting tooth 8 is fixed on the arc-shaped pressing plate 6, or the limiting tooth 8 is arranged on the shell 2 and the pressing plate 6. Preferably, the arrangement of the arc-shaped pressing plate 6 facilitates the pressing of the end of the belt 1, and also has a guiding effect on the belt 1 to avoid the jamming of the belt 1 in the shell 2. The shell 2 is provided with a counterbore or a stud 9 matched with the bolt 7. Preferably, the shell 2 is provided with the stud 9, the stud 9 is provided with an internal thread, and the belt 1 is punched to match the stud 9 during installation, which further improves the fixing effect on the end of the belt 1.

[0028] In this embodiment, the surface of the housing 2 is provided with an electroplated layer. This prevents the belt buckle 1 from rusting and scratching, and improves the appearance of the housing 2. Preferably, a decorative piece is provided on the outer side of the housing 2. The decorative piece is integrally formed with the housing 2, or the decorative piece is fixedly connected by welding or adhesive. The design of the decorative piece helps to improve the appearance of the belt buckle 1.

[0029] This invention adopts a symmetrical design for the housing 2, which is more visually harmonious. The straight inner line conforms to ergonomics. The groove 10 is set parallel to the inner line of the housing 2, which reduces the problem of the belt 1 being too tight on the roller 4 and improves the comfort of use. In addition, the method of connecting the belt 1 to the housing 2 by the detachable arc-shaped pressure plate 6, combined with the groove 10 being located at the front end of the belt buckle, avoids the problem of the roller belt having one end thick and the other thin when using a rotating connection method, thus solving the problem of the symmetrical design of the housing 2.

[0030] Preferably, the number of limiting teeth 8 is set to 4. The top of the limiting teeth 8 is rounded to avoid being too sharp and damaging the leather surface. The gap between the limiting teeth 8 on the housing 2 and the pressure plate 6 is half the thickness of the belt 1. The belt 1 can be made of split film double leather with a fabric reinforcement layer in the middle to maintain toughness and tensile strength, ensuring the durability and comfort of the belt 1. During use, holes are drilled at the end of the belt 1, the holes of the belt 1 are clamped on the stud 9 and fastened on the limiting teeth 8, and then the end of the belt 1 is fixed to the housing 2 by the pressure plate 6 and bolts 7. When in use, the belt 1 is passed through the housing 2 and adjusted to a suitable tension position. Then, the roller 4 is pulled to the left end of the housing 2 to tighten the belt 1. When loosening, the roller 4 is pulled to the other side along the slide groove 10 to loosen and remove the belt 1.

[0031] like Figure 4 As shown: This utility model of roller belt buckle has symmetrical 11 and 12, equal thickness of 13 and 14, the thickest part of 15 is located in the center of the buckle head, the inner line of 16 is straight, and the groove 10 is parallel to the inner line. Under the premise of keeping parallel to the inner line, the front end of the groove 10 is at the front end without affecting the buckle head's firmness, and the tail end of the groove 10 is at the thickest part of the buckle head. This achieves the goal of locking the belt body in front of the roller and allowing the belt body to pass smoothly behind. The buckle head's connection to the belt uses a combination of limiting teeth, studs, arc-shaped pressure plates, and bolts to tightly connect the belt body to the buckle head. The arc of the arc-shaped pressure plate ensures that it does not block the other end of the belt body from the roller while fixing the belt body, thus giving the buckle good belt body passage.

[0032] The above describes the preferred embodiment of this utility model and the technical principles used therein. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solution of this utility model without departing from the spirit and scope of this utility model shall fall within the protection scope of this utility model.
