Specific embodiments

[0021] In order to better understand the technical means of the present invention and implement it according to the content of the specification, the following further describes the specific embodiments of the present invention in detail with reference to the drawings and embodiments. The following embodiments are used to illustrate the present invention but not to limit the scope of the present invention.

[0022] A quick-change structure based on a light-load double-speed chain, as Figures 1 - 4 shown, includes symmetrically arranged profile bodies 1 and a chain detachably connected to the profile body 1. Adjacent profile bodies 1 are fixedly connected by a reinforcing rib 8. The profile body 1 is provided with a conveying cavity 2 for accommodating the upper half of the chain and a return cavity 3 for accommodating the lower half of the chain. The top of the conveying cavity 2 is open, and the top of the upper half of the chain extends out of the conveying cavity 2;

[0023] On both sides of the chain at the top of the profile body 1, an outer buckle strip 40 and an inner buckle strip 41 are detachably connected in the vertical direction respectively. On the side where the outer buckle strip 40 and the inner buckle strip 41 are close to each other, a limiting part 401 for restricting the chain from disengaging from the conveying cavity 2 in the vertical direction is provided. The setting of the limiting part 401 can make the upper half of the chain stably arranged in the conveying cavity 2; and the transportation surface of the chain for transporting materials extends out between the two limiting parts 401 to prevent the limiting part 401 from blocking the chain and thus affecting the transportation efficiency of the chain.

[0024] On both sides of the open part of the conveying cavity 2, there are respectively an outer guiding part 11 and an inner fixing part 12. The outer buckle strip 40 and the inner buckle strip 41 are respectively detachably connected to the outer guiding part 11 and the inner fixing part 12. The horizontal height of the outer guiding part 11 is greater than that of the inner fixing part 12. The setting of the outer guiding part 11 can limit and guide the transported materials, making the transportation of the materials more stable. Both the outer buckle strip 40 and the inner buckle strip 41 are made of PE plastic and have good elasticity. On both sides of the outer guiding part 11 and the inner fixing part 12, there are clamping grooves 13. At the bottom of the outer buckle strip 40 and the inner buckle strip 41, there are clamping parts 400 that cooperate with the clamping grooves 13. When the outer buckle strip 40 and the inner buckle strip 41 are buckled onto the outer guiding part 11 and the inner fixing part 12 in the vertical direction, the two clamping parts 400 are deformed and move away from each other. When fully buckled, the clamping parts 400 return to their original state through their own elasticity and extend into the clamping grooves 13, thereby restricting them from moving away in the vertical direction and completing the fixation of the outer buckle strip 40 and the inner buckle strip 41.

[0025] An installation groove 21 is formed on the inner bottom wall of the conveying cavity 2. A pair of symmetrically arranged load-bearing steel bars 6 are detachably connected in the installation groove 21, and there is a gap between the two load-bearing steel bars 6. An embedding groove 211 is formed on the inner side wall of the installation groove 21. The cross section of the load-bearing steel bar 6 is L-shaped and can be inserted into the embedding groove 211. The top of the load-bearing steel bar 6 extends into the conveying cavity 2 and contacts the inner side wall of the chain. The load-bearing steel bar 6 is provided to support and guide the chain, making the movement of the chain smoother. A groove 22 is formed on the inner bottom wall of the installation groove 21. A fixing member 221 is fixedly connected in the groove 22, and there is a gap between the fixing member 221 and the inner side wall of the groove 22. The top of the fixing member 221 is detachably connected with a pressing buckle strip 7 in the vertical direction. The two sides of the pressing buckle strip 7 are provided with extrusion parts 71 extending towards the side wall of the load-bearing steel bar 6. The pressing buckle strip 7 is also made of PE plastic and has good elasticity. When the pressing buckle strip 7 is inserted vertically between the two load-bearing buckle strips, the extrusion part 71 contacts the load-bearing steel bar 6 and deforms elastically by itself, so that the load-bearing steel bar 6 approaches the inner side wall of the installation groove 21 and is inserted into the embedding groove 211, thereby restricting the load-bearing steel bar 6 from detaching from the installation groove 21 in the vertical direction and completing the installation of the load-bearing steel bar 6. When the pressing buckle strip 7 is taken out of the groove 22, the load-bearing steel bar 6 can be easily taken out of the installation groove 21, which is convenient for the later maintenance or replacement of the load-bearing steel bar 6. A clamping part 400 is also provided at the bottom of the pressing buckle strip 7, and clamping grooves 13 are also formed on both sides of the fixing member 221. The clamping part 400 is embedded into the clamping groove 13 to complete the installation of the pressing buckle strip 7, so that the pressing buckle strip 7 can also be detachably connected with the fixing member 221 in the vertical direction. A depression is provided at the top of the pressing buckle strip 7, so that there is a gap between the chain and the pressing buckle strip 7, so that the chain will not touch the pressing buckle strip 7 during movement and will not cause wear, ensuring the service life of the pressing buckle strip 7 and affecting the fixing efficiency of the load-bearing steel bar 6.

[0026] On the inner bottom wall of the return cavity 3, protrusions 31 are symmetrically arranged. A return friction strip 32 is detachably connected to the protrusions 31 in the vertical direction. There is a gap between the two return friction strips 32. The return friction strip 32 is provided to support the lower half of the chain and ensure the smoothness of the chain movement.

[0027] Working principle: Place two load-bearing steel bars 6 in the installation groove 21 of the conveying cavity 2 and arrange them symmetrically with each other. When the press-fitting buckle strip 7 is inserted vertically between the two load-bearing buckle strips, the extrusion part 71 contacts the load-bearing steel bar 6 and through its own elastic deformation, the load-bearing steel bar 6 is made to approach the inner side wall of the installation groove 21 and inserted into the embedding groove 211, thereby restricting the load-bearing steel bar 6 from disengaging from the installation groove 21 in the vertical direction and completing the installation of the load-bearing steel bar 6; after placing the chain on the profile body 1, buckle the outer buckle strip 40 and the inner buckle strip 41 vertically on the outer guiding part 11 and the inner fixing part 12. The two clamping parts 400 on the outer buckle strip 40 and the inner buckle strip 41 deform and move away from each other. When fully buckled, the clamping parts 400 return to their original state through their own elasticity and extend into the clamping groove 13, thereby restricting them from moving away in the vertical direction and completing the fixation of the outer buckle strip 40 and the inner buckle strip 41. At this time, the limiting part 401 is located above the chain, enabling the upper half of the chain to be stably arranged in the conveying cavity 2.

[0028] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
