[0034] like Figure 1-9As shown, a new belt buckle is provided, comprising: a buckle body 1, a tail clip 2 is provided at the rear of the buckle body 1, and the tail clip 2 is used to clamp the belt; upwardly protruding convex parts 3 are provided on both sides of the front of the buckle body 1; a jumping rod 4, the jumping rod 4 is arranged between the convex parts 3, the jumping rod 4 is provided with a cavity 5 along the axial direction, the cavity 5 is provided with a groove 6 along the axial direction, and a clamping assembly 7 is provided on the circumferential surface of the jumping rod 4, and the clamping assembly 7 is used to clamp the belt; a spring 8, the spring 8 is arranged in the cavity 5, the first end of the spring 8 is provided with a first fixing strip 9 extending radially outward, the first fixing strip 9 is placed in the groove 6 and fixed to fix the spring 8; the second end of the spring 8 is provided with a second fixing strip 10 extending radially inward; a plug 11, the first end of the plug 11 is provided with a first clamping part 12 cooperating with the second fixing strip 10; the second end of the plug 11 is detachably connected to the convex part 3.

[0035] In view of the technical problems recorded in the background technology, a new belt buckle is provided. In the above technical solution, the tail clip 2 is used to clamp the belt, and a fixed tooth structure is set on the tail clip 2 to press and fix the belt by rotation. The belt can be a woven belt, an automatic buckle belt with grooves, or a toothless belt.

[0036] An integrally formed protrusion 3 is provided at both ends of the buckle body 1, and an opening 13 structure is provided on the protrusion 3. The opening 13 structure can be in the form of a round hole or a square hole, etc., and the specific selection is made according to the implementation situation. A jumper 4 is installed between the protrusions 3, and the jumper 4 has a cavity 5. The cavity 5 is in the form of a blind hole, that is, it passes through one end of the jumper 4 and is not passed through the other end of the jumper 4. A groove 6 is arranged transversely in the cavity 5. As for the structure of the spring 8, the first end of the spring 8 extends radially to form a first fixing strip 9. During installation, the first fixing strip 9 of the spring 8 is placed along the groove 6 to install and position the first end of the spring 8. A second fixing strip 10 is extended inwardly along the diameter at the second end of the spring 8, a plug 11 is provided at the second end of the spring 8, a first clamping portion 12 is provided on the plug 11 to connect with the second fixing strip 10 of the spring 8, and the first clamping portion 12 is designed as a clamping groove structure that cooperates with the second fixing strip 10. The torsional force of the spring 8 can be adjusted by rotating the plug 11. After appropriate adjustment, the second end of the plug 11 is connected and fixed to the opening 13 of the protrusion 3.

[0037] Through the above-mentioned structural setting, a groove 6 is set in the jumping rod 4, and the first fixing strip 9 of the spring 8 is placed in the groove 6 to fix the first end of the spring 8. A plug 11 is set in the other end of the jumping rod 4, and the plug 11 is provided with a first clamping portion 12 connected to the second fixing strip 10 of the spring 8, which makes the installation of the spring 8 more convenient; the traditional requirement of two plugs 11 is adjusted to only one plug 11.

[0038] The adjustment of the torsional force of the spring 8 is more convenient. The torsional force of the spring 8 can be adjusted by rotating the plug 11 with external force, and the pressing effect of the jumping rod 4 can be indirectly adjusted; the elastic force of the spring 8 is used to push the plug 11 out and cooperate with the protrusion 3 to limit the position.

[0039] When the belt is in use, after it has gone around a circle, it passes through the lower part of the jumping rod 4 and is pressed against the corresponding position on the belt by the clamping assembly 7 to limit the belt and fix the belt position. When the belt needs to be withdrawn, the jumping rod 4 is rotated by external force, driving the clamping assembly 7 to rotate until the resistance with the belt is released. At the same time, it will drive the twisting of the spring 8 in the jumping rod 4. Since the spring 8 is connected to the plug 11, the spring 8 plays the role of a torsion spring. When the external force disappears, the spring 8 will drive the jumping rod 4 and the clamping assembly 7 to reset, so that the clamping assembly 7 again presses against the belt to achieve locking; the spring 8 plays the dual role of elastic force and torsion spring, and the locking structure is simple in structure, reduces production cost, has a stable structure after installation, has good use effect, and is easy to be widely promoted.

[0040] like Figure 9 and Figure 11 As shown, an opening 13 is provided on the convex portion 3, and a first limiting portion 14 is provided at the first end of the jumping rod 4 embedded in the opening 13; the plug 11 is provided at the second end of the jumping rod 4 and embedded in the opening 13 of the convex portion 3 on the other side.

[0041] As a preferred embodiment, a first limiting portion 14 is set at the first end of the jumping rod 4. The first limiting portion 14 is in a cylindrical form, and the corresponding opening 13 of the convex portion 3 is set to a circular hole form. Therefore, the first limiting portion 14 is conveniently embedded in the opening 13 of the convex portion 3, which is convenient for installation and the jumping rod 4 can rotate relative to the convex portion 3 when rotating.

[0042] A second clamping portion 15 is provided at the second end of the plug 11 , and the second clamping portion 15 is embedded in the opening 13 of the protrusion 3 .

[0043] In order to keep the spring 8 having a torsional force in the jumper 4, the opening 13 connecting the protrusion 3 and the plug 11 is designed as a square hole to ensure that the connection between the plug 11 and the square hole of the protrusion 3 does not rotate. Under the action of the elastic force of the spring 8, the plug 11 is pushed out and fixed to the square hole of the protrusion 3, so that both ends of the spring 8 are fixed, ensuring that the spring 8 has a torsional force, and the jumper 4 is reset when the external force is removed.

[0044] like Figure 11 The jumping rod 4 is provided with a swinging portion 16 near the second end position, and the swinging portion 16 is driven by an external force to drive the jumping rod 4 to rotate, so that the clamping assembly 7 releases the clamping of the belt.

[0045] In order to facilitate the rotation of the jumping rod 4 and release the abutment limit on the belt, a swinging portion 16 is provided on the jumping rod 4, thereby making it convenient for the user to bend and rotate the jumping rod 4.

[0046] like Figure 9 and Figure 11 As shown, a step 17 is provided on the convex portion 3, and a blocking portion 18 is provided on the circumferential surface of the jumping rod 4 to cooperate with the step 17. The blocking portion 18 is used to limit the rotation of the jumping rod 4.

[0047] When the external force is removed, the jumping rod 4 is reset, and the blocking portion 18 provided on the jumping rod 4 contacts the step 17 on the convex portion 3, limiting the rotation angle of the jumping rod 4.

[0048] Reference Figure 12 As shown, the clamping assembly 7 includes a first clamping portion 19 arranged on the outer peripheral surface of the jumping rod 4 and a second clamping portion 20 arranged on one side of the first clamping portion 19. The height of the first clamping portion 19 is greater than the height of the second clamping portion 20, so that the first clamping portion 19 and the second clamping portion 20 are used to clamp belts of different thicknesses.

[0049] Since the clamping assembly 7 on the existing belt buckle is usually a single clamping part, it can only be adapted to automatic buckle belts, that is, automatic buckle belts with teeth and grooves, and cannot be applied to other belts.

[0050] To address this issue, a clamping assembly 7 is provided on the jumper 4. The clamping assembly 7 mainly includes a first clamping portion 19 and a second clamping portion 20. The first clamping portion 19 is higher than the second clamping portion 20. The first clamping portion 19 can be adapted to thinner belts, while the second clamping portion 20 can be adapted to thicker belts. In the design, the width of the second clamping portion 20 can be smaller than the first clamping portion 19, for example, the second clamping portion 20 can be designed to fit and securely engage with the tooth groove of an automatic buckle belt.

[0051] With this structural design, when using some thinner woven belts, the second clamping portion 20 can be used to abut against the woven belt, and when using some thicker belts or belts with grooves, the second clamping portion can be used to abut and fix them. It can adapt to various styles of belts and has better use effect.

[0052] The first clamping portion 19 and the second clamping portion 20 are bent toward the direction in which the belt enters the buckle body 1 so as to better fix the belt.

[0053] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
