Description

Technical Field

[0001] This utility model relates to the field of bracket installation technology, specifically to a bracket leg splicing buckle for laser instrument brackets. Background Technology

[0002] As a support carrier for precision optical equipment, the stability of the laser instrument's legs directly affects the positioning accuracy and safety of the laser instrument. Traditional leg splicing clips typically use metal materials to directly clamp the legs, which has the following drawbacks: direct contact between the metal clips and the legs is prone to wear, and the clamping force decreases after long-term use, leading to loosening of the legs; the low coefficient of friction of the metal surface makes it easy to slip during clamping, making it difficult to ensure the fixing accuracy of the legs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a support leg splicing buckle for laser instrument brackets. By installing a detachable anti-slip pad in the fixed buckle and flip buckle, the support leg is indirectly contacted and clamped, thus solving the problems of wear, slippage and insufficient stability caused by direct clamping of traditional buckles.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A leg splicing buckle for a laser instrument bracket includes a connecting shaft, two sets of fixed buckles rotatably mounted on the connecting shaft and arranged facing each other, a flip buckle rotatably connected to one end of the fixed buckle via a rotating shaft, and a locking structure fixedly connected to the end of the fixed buckle away from the rotating shaft; both the fixed buckle and the flip buckle are fitted with removable anti-slip pads, wherein the fixed buckle and the flip buckle indirectly clamp and fix the leg through the anti-slip pads.

[0006] By adopting the above solution, the splicing buckle of the support leg indirectly contacts the splicing buckle of the support leg through a detachable anti-slip pad. The elastic deformation and anti-slip texture of the anti-slip pad enhance the friction, while reducing direct wear and significantly improving the stability of the support leg fixation.

[0007] In a preferred embodiment of the splicing buckle for the legs of a laser instrument bracket, the anti-slip pad inside the fixing buckle is a flat anti-slip pad. Its flat design is for better fitting the end face of the connecting shaft. The surface of the flat anti-slip pad facing away from the leg has at least one protrusion arranged in a linear array. The end face of the connecting shaft inside the fixing buckle has a groove that mates with the protrusion. The anti-slip pad inside the flip buckle is an arc-shaped anti-slip pad. Its arc-shaped design is for better fitting the surface of the flip buckle. The surface of the arc-shaped anti-slip pad facing away from the leg has at least one protrusion arranged in a circumferential array. The inner surface of the fixing buckle has a groove that mates with the protrusion. By using an interference fit for both the protrusion and the groove, the anti-slip pad can be quickly installed and positioned, preventing it from falling off during clamping and further enhancing the fixing reliability of the anti-slip pad.

[0008] In a preferred embodiment of the splicing buckle for the legs of a laser instrument bracket, the flat anti-slip pad has protruding clamps at both ends of the side facing the leg. When the flat anti-slip pad contacts the leg, only the clamps at both ends contact the leg. Similarly, the curved anti-slip pad has protruding clamps at both ends of the side facing the leg. When the curved anti-slip pad contacts the leg, only the clamps at both ends contact the leg. This design reduces the contact area between the anti-slip pad and the leg, concentrating the clamping force at both ends, resulting in four-point force application on the leg. This avoids leg deformation due to excessive pressure in the middle area and increases the friction per unit area by reducing the contact area.

[0009] As a preferred embodiment of the splicing buckle for the legs of a laser instrument bracket, the anti-slip pad is integrally molded from an elastic material (such as rubber or silicone). The elastic material allows the anti-slip pad to undergo elastic deformation when compressed, filling the tiny bumps and depressions on the surface of the legs and enhancing friction. The surface facing the legs is provided with multiple anti-slip textures. These multiple anti-slip textures (such as grid patterns, stripes, or dotted protrusions) further increase the roughness of the contact interface, effectively preventing the legs from sliding.

[0010] In a preferred embodiment of the leg splicing buckle for a laser instrument bracket, the locking structure includes a locking bolt fixedly connected to one end of the fixed buckle, a locking groove formed at the corresponding end of the flip buckle, and a locking nut mounted on the locking bolt and capable of locking the flip buckle. By rotating the locking nut, the clamping force between the flip buckle and the fixed buckle can be adjusted to ensure that the anti-slip pad fits tightly against the leg, thus achieving self-locking fixation.

[0011] In a preferred embodiment of the support leg splicing buckle for a laser instrument bracket, the side of the connecting shaft has two annular grooves, each adjacent to a fixing buckle. An annular retaining ring is installed within each groove, and one side of the retaining ring has an opening for adjusting the tightness. The elastic deformation of the retaining ring through the opening adjusts the tightness of its fit with the connecting shaft. This tightness can be adjusted using needle-nose pliers, thus preventing the fixing buckle from detaching from the connecting shaft.

[0012] The beneficial effects of this utility model are:

[0013] 1. Indirect contact reduces wear: The anti-slip pads indirectly contact the feet, avoiding direct friction between the metal clips and the feet, thus extending the service life of the clips and feet.

[0014] 2. Elastic anti-slip for enhanced stability: The elastic anti-slip pad, combined with the anti-slip texture, deforms and fills the defects on the surface of the support leg when under pressure, increasing friction and significantly improving clamping stability;

[0015] 3. Detachable design for easy maintenance: The anti-slip mat is installed using a locking mechanism with protrusions and slots, making it easy to disassemble and replace, thus reducing maintenance costs;

[0016] 4. Concentrated clamping force to prevent deformation: The design with only two ends in contact concentrates the clamping force, preventing deformation in the middle area of ​​the legs due to excessive pressure, while also increasing the friction per unit area. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] like Figures 1 to 3 , Figure 9 As shown, a leg-joining buckle for a laser instrument bracket is provided, used to fix the legs of the laser instrument bracket to each other. Specifically, it includes a connecting shaft 1, two sets of fixing buckles 2 rotatably mounted on the shaft of the connecting shaft 1 and facing each other, a flip buckle 4 rotatably connected to one end of the fixing buckle 2 via a rotating shaft 3, and a locking structure fixedly connected to the end of the fixing buckle 2 away from the rotating shaft 3. Both the fixing buckle 2 and the flip buckle 4 have removable anti-slip pads installed within them, and the fixing buckles 2 and the flip buckle 4 indirectly clamp and fix the legs 5 (only part shown in the figure) through the anti-slip pads. The leg-joining buckle indirectly contacts the leg 5's joint buckle through the removable anti-slip pads, utilizing the elastic deformation and anti-slip texture of the anti-slip pads to enhance friction while reducing direct wear, significantly improving the stability of the fixed legs 5.

[0030] like Figures 4 to 8As shown, the anti-slip pad inside the fixing buckle 2 is a flat anti-slip pad 6. Its flat design is to better fit the end face of the connecting shaft 1. The surface of the flat anti-slip pad 6 facing away from the support leg 5 has at least one protrusion 7 (there are three in total in the figure). The end face of the connecting shaft 1 inside the fixing buckle 2 has a groove 8 that mates with the protrusion 7. The anti-slip pad inside the flip buckle 4 is an arc-shaped anti-slip pad 9. Its arc-shaped design is to better fit the surface of the flip buckle 4. The surface of the arc-shaped anti-slip pad 9 facing away from the support leg 5 has at least one protrusion 10 (there are three in total in the figure). The inner surface of the fixing buckle 2 has a groove 11 that mates with the protrusion 10. The protrusions and grooves are all interference fits to achieve quick installation and positioning of the anti-slip pad, prevent the anti-slip pad from falling off during clamping, and further enhance the fixing reliability of the anti-slip pad.

[0031] like Figure 3 , Figures 7 to 8 As shown, the flat anti-slip pad 6 has protruding clamps 12 at both ends of the surface facing the support leg 5. When the flat anti-slip pad 6 contacts the support leg 5, only the clamps 12 at both ends contact the support leg 5. The curved anti-slip pad 9 has protruding clamps 23 at both ends of the surface facing the support leg 5. When the curved anti-slip pad 9 contacts the support leg 5, only the clamps 23 at both ends contact the support leg 5. This design reduces the contact area between the anti-slip pad and the support leg 5, concentrating the clamping force at both ends, and the support leg 5 forms a four-point force distribution (see [link to relevant documentation]). Figure 3 This design avoids deformation of the support legs 5 in the middle area due to excessive pressure, and also increases the friction per unit area by reducing the contact area.

[0032] Continue as Figures 7 to 8 As shown, the anti-slip mat is made of an elastic material (such as rubber or silicone) in one piece. The elastic material allows the anti-slip mat to deform elastically when pressed, filling the tiny bumps and depressions on the surface of the foot 5 and enhancing the friction. The surface facing the foot 5 has multiple anti-slip grooves with a depth of 1mm, which can be in the range of 0.5-2mm. The multiple anti-slip grooves (such as grid patterns, stripes or dotted protrusions) further increase the roughness of the contact interface, effectively preventing the foot 5 from sliding.

[0033] like Figure 2 As shown, the locking structure includes a locking bolt 14 fixedly connected to one end of the fixed buckle 2, a locking groove 15 opened at the corresponding end of the flip buckle 4, and a locking nut 16 assembled on the locking bolt 14 and capable of locking the flip buckle 4. By rotating the locking nut 16, the clamping force between the flip buckle 4 and the fixed buckle 2 can be adjusted to ensure that the anti-slip pad and the support leg 5 fit tightly together, thus completing the self-locking fixation.

[0034] like Figure 9As shown, the side of the connecting shaft 1 has two annular grooves 17 respectively close to the fixing buckle 2. An annular retaining ring 18 is installed in the annular groove 17 for limiting, and an opening for adjusting the tightness is opened on one side of the annular retaining ring 18. The tightness of the annular retaining ring 18 with the connecting shaft 1 can be adjusted by the elastic deformation of the opening. The tightness can be adjusted with needle-nose pliers, thereby preventing the fixing buckle 2 from falling off the connecting shaft 1.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
