The utility model sets a rotating ring and a limiting rod, and the rotating ring is bonded and rollingly connected to the two sides of the guide wheel, so as to realize the limiting effect of the guide wheel by the limiting rods on both sides, and because the rotating ring can rotate, it has no effect on the outer surfaces of the two sides of the guide wheel that affects the rotation of the guide wheel;

[0004] The guide wheel axle seat in this patent requires the disassembly of parts during installation, and requires manual coordination for positioning and installation. During use, the inclination angle of the guide wheel cannot be adjusted accordingly according to the actual installation requirements on site, and the installation is not very convenient.

[0015] Beneficial effects:

[0016] The guide wheel axle seat that can be quickly disassembled and assembled is provided with the first fixing bracket, the second fixing bracket, the limiting plate and the guide wheel clamping assembly. When the guide wheel is installed, the first fixing bracket and the second fixing bracket can be directly pulled outward so that the guide wheel can be placed in the guide wheel clamping assembly, and the self-limiting clamping effect is realized by the guide wheel clamping assembly to fix the shafts at both ends of the guide wheel.

By cooperating with each other, the rotational position of the first rotating plate 6 and the second rotating plate 8 can be fixed to avoid the inclination angle of the first rotating plate 6 and the second rotating plate 8 from being offset during use. The lower ends of the first fixed bracket 3 and the second fixed bracket 4 are fixedly installed with a slider 12, and the outer side of the slider 12 is fixedly connected with a telescopic spring 13. Through the setting of the telescopic spring 13, when installing the guide wheel, the first fixed bracket 3 and the second fixed bracket 4 can be directly pulled outward so that the guide wheel can be placed in the guide wheel clamping assembly 7. The guide wheel clamping assembly 7 realizes a self-limiting clamping effect to fix the shafts at both ends of the guide wheel. After loosening the first fixed bracket 3 and the second fixed bracket 4, they move inward by the elastic force of the lower telescopic spring 13, thereby clamping the two ends of the guide wheel. It is very convenient to install and disassemble.

[0024] A snap ring 14 is provided on the outside of the connecting shaft 11, and a groove corresponding to the snap ring 14 is provided on the outside of the limiting plate 5. Through the cooperation between the snap ring 14 and the groove, the first rotating plate 6 and the second rotating plate 8 can be firmly fixed on the limiting plate 5. The other end of the telescopic spring 13 is fixedly installed on the inner wall of the fixed frame 2. A sliding groove corresponding to the slider 12 is provided on the surface of the fixed frame 2.
