Technical Field

[0001] This utility model relates to the field of belt buckle technology, specifically a novel belt buckle. Background Technology

[0002] Belt buckles are an important component of belts, mainly used to secure and adjust the tightness of the belt. Depending on their design, material, and function, belt buckles can be divided into various types.

[0003] Existing belt buckles have a very simple structure. They are generally limited by pressing and only have a limiting function. This makes them prone to slipping when pulled from the outside, affecting their stability. Furthermore, their single function affects the user experience.

[0004] Therefore, a new type of belt buckle is proposed to solve the problems mentioned above. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a new type of belt buckle that can solve the problems of single function and insufficient tightness.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a fixed base and a pressing piece rotatably mounted on one side of the fixed base, wherein a placement groove is provided in the middle of the pressing piece, and a guide frame is fixedly provided on the side of the fixed base away from the pressing piece;

[0007] The outer side of the rotating part of the pressing piece is provided with several positioning cones. A ventilation groove is provided through the bottom of the placement groove. The ventilation groove is connected to the outer side of the fixed base. A rotating support groove is provided below the guide frame. A limiting arc frame is rotatably provided inside the rotating support groove. An arc-shaped support cone groove is provided in the middle of the upper end of the limiting arc frame.

[0008] Preferably, the positioning cones are horizontally and evenly distributed, and a fastening plate is provided on the inner side of the upper end of the pressing plate, which is engaged with one side of the inside of the fixing seat.

[0009] Preferably, one side of the inner wall of the placement groove is in close contact with the fastening plate, and a limiting plate is provided on the other side of the placement groove. The limiting plate is used for limiting and supporting the placement of the aromatherapy material.

[0010] Preferably, a pressing handle is rotatably provided on the outer side of the guide frame, and the inner rotating shaft of the pressing handle passes through one side of the fixed seat and the rotating shaft passes through the limiting arc frame.

[0011] Preferably, the limiting arc frame has a positioning groove inside, the limiting arc frame is inserted into the positioning groove, and a return spring is sleeved on the outside of the limiting arc frame. One end of the return spring is fixedly disposed on the inner wall side of the positioning groove, and the other end of the return spring is fixedly disposed inside the fixing seat near the placement groove.

[0012] Preferably, at least two limiting blocks are provided on the outer side of the limiting arc frame, and the limiting blocks are used for limiting support.

[0013] Preferably, the outer side of the support cone groove is provided with a plurality of auxiliary cones, and the part of the auxiliary cones that contacts the waist belt is cone-shaped.

[0014] Compared with the prior art, this utility model provides a novel belt buckle, which has the following beneficial effects:

[0015] 1. By setting the support cone groove into a V-shaped structure, the waist belt deforms under pressure, and the V-shaped space provides space for its deformation. Then, the shorter side at the rear end comes into contact with the waist belt by compression, and the space where the compression and deformation occur also moves into the V-shaped space, forming a double sequential limiting.

[0016] 2. The placement slot provides space for aromatherapy materials, and the ventilation slot facilitates the release of the aromatherapy materials' scent.

[0017] 3. Under the elastic action of the return spring, the limiting arc frame automatically returns to the vertical position, causing the support cone groove to press against the waist belt, thus creating a limiting effect on the waist belt.

[0018] 4. By setting two limit blocks, the limit blocks are made to contact the bottom surface of the rotating support groove when the limit arc frame rebounds and resets, so that the limit arc frame can be in an accurate vertical state.

[0019] 5. By setting several auxiliary cones on the two top edges of the support cone groove, and by using the cone-shaped support of the auxiliary cones themselves, it is easy to increase the pressure on the waist belt and improve the fastening strength of the waist belt positioning.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1 - Figure 4 A novel belt buckle in this embodiment includes a fixed base 1 and a pressing piece 2 rotatably mounted on one side of the fixed base 1. The pressing piece 2 has a placement groove 4 in the middle, and a guide frame 3 is fixedly provided on the side of the fixed base 1 away from the pressing piece 2.

[0028] Several positioning cones 202 are provided on the outer side of the rotating part of the pressing plate 2. A ventilation groove 401 is provided through the bottom of the placement groove 4. The ventilation groove 401 is connected to the outer side of the fixed base 1. A rotating support groove 301 is provided below the guide frame 3. A limiting arc frame 302 is rotatably provided inside the rotating support groove 301. An arc-shaped support cone groove 305 is provided in the middle of the upper end of the limiting arc frame 302.

[0029] The positioning cone 202 on the pressing plate 2 can lock the belt and prevent it from slipping. The placement groove 4 provides a space for the aromatherapy material (such as aromatherapy tablets). The ventilation groove 401 facilitates the release of the aromatherapy material's scent. The guide frame 3 provides guidance and support for the placement of the belt, ensuring the accuracy of the belt's direction of use.

[0030] Furthermore, by setting the support cone groove 305 into a V-shaped structure, with a higher front and lower back, and an arc shape, within a distance of 1.5-3CM from the top, the front end of the support cone groove 305 first presses against the waist belt. At this time, the waist belt deforms, and the V-shaped space can provide space for its deformation. Then, the lower rear end presses against the waist belt, and the space where the compression and deformation occur also moves into the V-shaped space, forming a double sequential limiting effect and providing placement space for material deformation.

[0031] By setting both top edges of the support cone groove 305 to be arc-shaped, it is designed so that the middle part is limited to contact with the waist belt, and after gradual compression, the two sides then contact and compress with the waist belt, thus creating a limiting effect of different degrees.

[0032] The positioning cones 202 are horizontally and evenly distributed. A fastening piece 201 is provided on the inner side of the upper end of the pressing piece 2. The fastening piece 201 is engaged with one side of the inside of the fixing base 1.

[0033] One side of the inner wall of the placement groove 4 is in close contact with the fastening plate 201, and the other side of the interior of the placement groove 4 is provided with a limiting plate 402, which is used for limiting support for the placement of aromatherapy materials.

[0034] The combination of placement slot 4, limiting plate 402, and fixing seat 1 provides more space for the placement of aromatherapy materials. The aromatherapy materials can be placed either internally or externally. By adjusting the position of ventilation slot 401, which is opened on the lower surface of placement slot 4 or on the side of placement slot 4, the aromatherapy materials can release their scent through the surface or side openings, thus improving the versatility and comfort of the device.

[0035] A pressing handle 308 is rotatably provided on the outer side of the guide frame 3. The inner rotating shaft of the pressing handle 308 passes through one side of the fixed base 1, and the rotating shaft passes through the limiting arc frame 302.

[0036] The limiting arc frame 302 has a positioning groove 304 inside. The limiting arc frame 302 is inserted into the positioning groove 304. A return spring 306 is sleeved on the outside of the limiting arc frame 302. One end of the return spring 306 is fixedly set on the inner wall side of the positioning groove 304, and the other end of the return spring 306 is fixedly set on the side of the fixed base 1 near the placement groove 4.

[0037] At least two limiting blocks 303 are provided on the outer side of the limiting arc frame 302, and the limiting blocks 303 are used for limiting support;

[0038] By pressing the handle 308, the rotating shaft and the limiting arc frame 302 rotate synchronously, and the return spring 306 is in a contracted state, so that the upper end of the limiting arc frame 302 gradually moves inward to a horizontal position. After the waist belt passes through the guide frame 3 and the limiting arc frame 302, the handle 308 is released. Under the elastic action of the return spring 306, the limiting arc frame 302 automatically returns to a vertical position, so that the support cone groove 305 is pressed into contact with the waist belt, forming a limiting effect on the waist belt.

[0039] Among them, under the combined support of two return springs 306, and by adjusting the direction of the limit block 303, the control mode of the pressing handle 308 can be pressed to the left or moved to the right, so that the adjustment direction of the limit arc frame 302 has multiple options.

[0040] Among them, such as Figure 3As shown in the placement part, a support groove is provided on the outer side of the rotating shaft. By setting the return spring 306 inside the support groove, and combining the simultaneous positioning of the return spring 306 at both ends, a limiting space is provided for the return spring 306, further ensuring the accurate and reliable position of the return spring 306 when it acts elastically.

[0041] Specifically, by setting two rotating shafts inside the positioning groove 304, rotational support is provided on both sides of the limiting arc frame 302, and the rotating shafts are fixedly connected to the limiting arc frame 302 to provide stable rotational support for the limiting arc frame 302. Under the elastic support of the two return springs 306, the required tightening force is ensured when the limiting arc frame 302 is reset and tightened. By fixing both ends of the limiting arc frame 302 to the limiting arc frame 302 and the fixed seat 1 respectively, the stability of the position of the return spring 306 when it acts elastically is ensured.

[0042] By setting two limiting blocks 303, when the limiting arc frame 302 rebounds and resets, the limiting blocks 303 contact the bottom surface of the rotating support groove 301 to limit the movement, so that the limiting arc frame 302 can be in an accurate vertical state.

[0043] Example 2:

[0044] The outer side of the support cone groove 305 is provided with several auxiliary cones 307, and the part of the auxiliary cones 307 that contacts the belt is cone-shaped;

[0045] By setting several auxiliary cones 307 on the two top edges of the support cone groove 305, and by using the cone-shaped support of the auxiliary cones 307 themselves, it is easy to increase the pressure on the waist belt and improve the fastening strength of the waist belt positioning.

[0046] Furthermore, the direction of the support cone groove can be adjusted to be vertical, outward, or inward, all of which can achieve the corresponding fastening effect, while providing multiple options for the device.

[0047] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
