[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A manual film rolling cart includes a main body 1. A base plate 2 is symmetrically fixedly installed at the bottom of the main body 1. Two casters 3 with self-locking function are rotatably installed on the rear sides of the two base plates 2. Support seats 4 are symmetrically fixedly installed on the front sides of the base plates 2. Rotation grooves are formed on the upper surfaces of the two support seats 4, and support bearings 5 ​​are inserted into the two rotation grooves. A roller 6 is provided between the two support seats 4. A connecting shaft 7 is horizontally fixedly installed on the roller 6. The two ends of the connecting shaft 7 are respectively inserted into the inner rings of the two support bearings 5. Bearing seat covers 9 are installed on both support seats 4 by bolt fasteners 8.

[0024] The roller 6 is fixedly sleeved in the middle of the connecting shaft 7. When installing the roller 6, two support bearings 5 ​​are respectively sleeved on both ends of the connecting shaft 7. Then, the two support bearings 5 ​​are placed in the rotating grooves opened in the two support seats 4. The roller 6 is installed between the two support seats 4. Then, the bearing seat cover 9 is placed on top of the support seat 4. The support bearings 5 ​​are pressed between the support seat 4 and the bearing seat cover 9. The support seat 4 and the bearing seat cover 9 are fixed together with bolts and fasteners 8, thus completing the installation of the roller 6. The heavy-duty roller 6 structure greatly enhances the load-bearing capacity of the manual film rolling cart, which can easily cope with the transportation of film rolls of various weights. It greatly reduces the damage to the roller 6 caused by insufficient support force and reduces the cost of use.

[0025] The support bearing 5 is a tapered roller bearing, which is press-fitted between the support seat 4 and the bearing seat cover 9. The support bearing 5 is a high-precision tapered roller bearing with high load capacity. This type of bearing can withstand radial load and axial load at the same time, ensuring the stability and smoothness of the roller 6 during operation.

[0026] Both ends of the connecting shaft 7 are provided with annular grooves 10, and elastic retaining rings 11 are embedded in both annular grooves 10. A positioning ring 12 is provided between the elastic retaining ring 11 and the support base 4. A rotating ring 13 is rotatably mounted on the side of the positioning ring 12. The positioning ring 12 and the rotating ring 13 are sandwiched between the support base 4 and the elastic retaining ring 11. The positioning ring 12 contacts the support base 4 and the bearing housing cover 9, and the rotating ring 13 contacts the elastic retaining ring 11. An annular rotating groove is provided on the side of the positioning ring 12. The longitudinal section of both the rotating groove and the rotating ring 13 is an isosceles trapezoid. The rotating ring 13 is rotatably inserted into the rotating groove.

[0027] Two elastic retaining rings 11 are fitted into the annular grooves 10 at both ends of the connecting shaft 7. Due to the elasticity of the material of the elastic retaining rings 11, the positioning ring 12 and the rotating ring 13 are clamped between the support base 4 and the elastic retaining rings 11. The elastic retaining rings 11 are located on the outside of the two support bases 4, which can restrict the axial movement of the connecting shaft 7 during rotation and ensure the stability of the roller 6 when rolling. When the connecting shaft 7 rotates, it drives the elastic retaining rings 11 to rotate together. The elastic retaining rings 11 contact the rotating ring 13. Under the action of mutual friction, the rotating ring 13 can be driven to rotate on the positioning ring 12. The elastic retaining rings 11 can reduce the friction between themselves and the support base 4 through the action of the positioning ring 12 and the rotating ring 13. The longitudinal section of the rotating ring 13 and the rotating groove is an isosceles trapezoid, which can prevent the rotating ring 13 from detaching from the rotating groove.

[0028] The surface of roller 6 is designed with anti-slip patterns, with a depth of 3mm. The surface of roller 6 undergoes a special heat treatment process, significantly increasing its surface hardness and enhancing its wear resistance. Simultaneously, the diameter of roller 6 is significantly larger than that of the traditional omnidirectional wheel 3. The larger diameter of roller 6 effectively distributes the weight carried by the film-rolling cart, reducing pressure per unit area and further improving load-bearing capacity. The unique anti-slip pattern on the surface of roller 6 provides better friction under different road conditions, preventing slippage during operation and significantly improving the stability and safety of the manual film-rolling cart.

[0029] In this invention, the roller 6 is fixedly sleeved in the middle of the connecting shaft 7. When installing the roller 6, two support bearings 5 ​​are respectively sleeved on both ends of the connecting shaft 7, and then the two support bearings 5 ​​are respectively placed in the rotating grooves opened in the two support seats 4. The roller 6 is installed between the two support seats 4, and then the bearing seat cover 9 is placed on top of the support seat 4. The support bearings 5 ​​are pressed between the support seat 4 and the bearing seat cover 9. The support seat 4 and the bearing seat cover 9 are fixed together with bolts and fasteners 8, thereby completing the installation of the roller 6. The heavy-duty roller 6 structure greatly enhances the load-bearing capacity of the manual film rolling cart, which can easily cope with the transportation of film rolls of various weights, greatly reducing the damage to the roller 6 caused by insufficient support force and reducing the cost of use.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
