[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, such as Figure 1 - Figure 3As shown, this utility model provides a quick-assembly buckle for building templates, including a building template body 1. A length adjustment component 2 is inserted into the building template body 1. The length adjustment component 2 includes a pin 201. A slot 202 is formed on the front surface of the pin 201. A locking block 203 is inserted into the slot 202. A through hole 204 is formed inside the locking block 203. A hole 205 is formed inside the pin 201. A moving block 206 is disposed inside the hole 205. A slider 207 is connected to both the upper and lower ends of the moving block 206. A groove 208 is formed on the inner wall of both the upper and lower ends of the hole 205. A bearing 209 is disposed on one inner wall of the moving block 206. A connecting rod 210 is connected to one side of the bearing 209. A screw body 211 is connected to one side of 210. A handle 212 is fixedly connected to the outer surface of the screw body 211. A threaded groove 213 is opened at the position where the pin 201 matches the screw body 211. The screw body 211 and the pin 201 are threadedly connected through the threaded groove 213. The connecting rod 210 is rotatably connected to the moving block 206 through the bearing 209. The moving block 206 is cylindrical in shape. The inner wall of the slide groove 208 is in contact with the outer surface of the slider 207. The slider 207 and the slide groove 208 are slidably connected. The position and size of the slot 202 match the position and size of the block 203. The block 203 is trapezoidal in shape. The block 203 and the slot 202 are engaged.

[0030] The effect achieved in Embodiment 1 is that when it is necessary to insert the pin 201 into the building template body 1 of different thicknesses for fixing, the length of the pin 201 can be quickly adjusted by rotating the handle 212 in the opposite direction. When the handle 212 rotates, it drives the screw body 211 to rotate synchronously. The screw body 211 generates axial displacement through the thread engagement with the pre-set threaded groove 213 in the pin 201, and then moves outward. During this process, the screw body 211 converts the rotational force into the linear motion of the moving block 206 through the connecting rod 210. The moving block 206 maintains smooth sliding under the constraint of the guide structure formed by the slider 207 and the groove 208, ensuring that there is no deviation during the adjustment process. At the same time, the setting of the bearing 209 effectively isolates the rotation of the screw body 211. The screw thread transmission mechanism ensures the continuity and accuracy of the length adjustment, avoiding the rotation of the moving block 206 and achieving only axial extension and retraction. When it is necessary to shorten the pin 201 to accommodate a thinner template, rotating the handle 212 in the forward direction will cause the screw body 211 to rotate in the reverse direction. The inward contraction of the moving block 206 will drive the pin 201 to shorten as a whole. The entire adjustment process can be completed by operating the handle 212 with one hand. Compared with the traditional segmented or snap-on adjustment structure, the operation steps are significantly simplified. The threaded transmission mechanism ensures the continuity and accuracy of the length adjustment and avoids structural wear caused by frequent disassembly and assembly. Ultimately, the pin 201 can be efficiently adapted to templates of different thicknesses, greatly improving construction efficiency and tool usability. Then, the locking block 203 can be fixed by inserting it into the locking slot 202 with a tool hammer.

[0031] Example 2, as Figure 3 and Figure 6 As shown, a spacing adjustment component 3 is provided on the outside of the pin 201. The spacing adjustment component 3 includes a fixing frame 301. A bidirectional screw 302 is inserted into the inside of the fixing frame 301. A handle 303 is fixedly connected to the top of the bidirectional screw 302. Two sets of adjustment blocks 304 are symmetrically connected to the surface of the bidirectional screw 302. Threaded holes 305 are opened through the inside of both sets of adjustment blocks 304. A lifting frame 306 is fixedly connected to the outer surface of the threaded holes 305. The bidirectional screw 302 forms a threaded connection with the adjustment blocks 304 through the threaded holes 305. The adjustment blocks 304 are rectangular in shape, and the outer surface of the adjustment blocks 304 is in contact with the inner wall of the fixing frame 301.

[0032] The effect achieved in Embodiment 2 is that when the spacing needs to be adjusted, rotating the handle 303 drives the bidirectional screw 302 to rotate. Its symmetrical threaded sections form a helical transmission with the threaded holes 305 of the two sets of adjusting blocks 304. According to the difference in the direction of the thread, the two sets of adjusting blocks 304 move synchronously in opposite directions along the screw axis, thereby driving the lifting frame 306 and the pin 201 to move at equal distances or close together. This design ensures that the adjusted spacing remains stable under vibration conditions through its self-locking characteristics. At the same time, the fixing frame 301 is made of welded steel, which effectively improves the overall resistance to deformation. In actual use, the operator only needs to rotate the handle 303 with one hand to achieve a spacing adjustment with a precision of 0.5mm. Compared with the traditional solution where the pin 201 needs to be adjusted separately, this component improves the efficiency of template installation and has a wider range of adaptable hole spacing, meeting the installation needs of most building templates.

[0033] Working principle: When the length of the pin 201 needs to be adjusted, the handle 212 can be turned to drive the screw body 211 to rotate, and the overall length of the pin 201 can be adjusted through the threaded connection. The operation is simpler. After that, the adjusted pin 201 is inserted into the building formwork body 1 and fixed by inserting the locking block 203 into the locking slot 202. This avoids the problem of the cumbersome process of adjusting the length of the existing pin 201 and improves the practicality of the pin 201. When using the pin 201 to fix the building formwork body 1, the pin 201 can also be inserted through the lifting frame 306, so that the two sets of pins 201 can be fixed by the fixing frame 301 to improve stability. The fixing frame 301 also has the function of adjusting the distance between the two sets of lifting frames 306, which is convenient for use in different environments.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
