[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 5The utility model provides an embodiment: a non-powered resin roller, including a base 1, a plug-in tube 2 is fixedly connected to the left and right sides of the base 1, the two plug-in tubes 2 are arranged in mirror image, and the two plug-in tubes 2 are arranged on the separated sides of the two plug-in tubes 2. A notch 1 is provided on the side of the plug-in tube 2 away from the base 1, and a notch 2 is provided on the side of the plug-in tube 2 3 close to the base 1. A slide groove 13 is arranged on the inner wall of the notch 1 and a slide rail 12 is arranged on the inner wall of the notch 2. The slide rail 12 is slidably connected to the inside of the slide groove 13, and a telescopic airbag 11 is arranged inside the plug-in tube 1 2 and the plug-in tube 2 3. The outer walls of the plug-in tubes 1 2 at both ends and the plug-in tubes 2 3 at both ends are sleeved with resin jackets 14. Bearings 4 are provided on the separated sides of the two plug-in tubes 2 3, and a connecting shaft 6 is sleeved inside the bearing 4;

[0026] Specifically, the resin jacket 14 has a smooth surface property, which can significantly reduce the friction between the roller and the object being transported, and can effectively protect the surface of the object being transported from damage or wear, especially when transporting fragile or high-value items, to prevent scratches or damage caused by friction. Insertion barrel 1 2 and insertion barrel 2 3 are made of stainless steel, have a certain rigidity and strength, and can carry the transportation of heavy objects, thereby extending the service life of the roller. When the notch on the insertion barrel 2 3 moves and slides along the notch on the insertion barrel 1 2, the slide rail 12 will slide along the slide groove 13 to prevent the displacement of the insertion barrel 2 3, thereby improving the stability of the elongated structure.

[0027] Reference Figure 2 and Figure 3 , two telescopic airbags 11 are arranged in a mirror image, one end of the telescopic airbag 11 is fixedly connected to the inner wall of the insert tube 2 3, and the other end of the telescopic airbag 11 is fixedly connected to the side of the base 1 close to the insert tube 1 2, and a connecting air pipe 9 is fixedly located inside the base 1, and both the left and right ends of the connecting air pipe 9 are connected to the telescopic airbag 11, and the front end of the connecting air pipe 9 passes through the front side of the base 1, and an air plug 10 is arranged on the front side of the base 1, and the rear end of the air plug 10 is threadedly connected to the inside of the connecting air pipe 9;

[0028] Specifically, when the length of the roller needs to be extended, the air plug 10 is opened and gas is injected into the connecting air pipe 9, so that the gas enters the telescopic airbag 11 along the connecting air pipe 9, thereby expanding and extending the telescopic airbag 11, pushing the insert tube 2 3 to slide on the insert tube 1 2, and after the length adjustment is completed, the air plug 10 is plugged back into the air inlet of the connecting air pipe 9, and the resin jacket 14 of corresponding length is sleeved on the outer wall of the insert tube 1 2 and the insert tube 2 3. The telescopic airbag 11 is used to support the insert tube 1 2 and the insert tube 2 3 to prevent retraction, improve the stability of the elongation structure, and can adapt to various specifications of external structures for installation after the length adjustment, and carry out transportation and loading work, which greatly improves the flexibility of the roller.

[0029] Reference Figure 4 A cavity is formed inside the sleeve 7 fixedly connected to the outer wall of the connecting shaft 6. A plurality of snap-fit ​​springs 8 are arranged on the outer wall of the connecting shaft 6. The end of the snap-fit ​​springs 8 away from the connecting shaft 6 penetrates the outer wall of the sleeve 7. The outer wall of the end of the insert sleeve 3 close to the connecting shaft 6 is threadedly connected with a plurality of abutment bolts 5. The end of the abutment bolts 5 close to the connecting shaft 6 abuts against the outer wall of the bearing 4.

[0030] Specifically, the abutment bolt 5 is used to increase the fixation of the insert sleeve 2 3 on the outer wall of the bearing 4 to stabilize the rolling of the roller. When the insert sleeve 1 2 and the insert sleeve 2 3 and the base 1 rotate using the connected bearing 4, the insert sleeve 2 3 is prevented from slipping on the bearing 4 to prevent idling, and then the roller is rotated using the bearing 4 with higher rotation efficiency to improve the efficiency and stability of feeding. The sleeve 7 is used to connect to the connection of the structure used to connect the roller outside. When the sleeve 7 is inserted into the connection, the snap-on spring piece 8 will be deformed, so that the sleeve 7 can enter the connection normally. After the sleeve 7 enters the connection, the reset of multiple snap-on spring pieces 8 will abut against the inner wall of the connection, increasing the friction between the sleeve 7 and the inner wall of the connection, preventing the sleeve 7 from spinning at the connection, thereby improving the stability of the roller rotation.

[0031] Working principle: When installing the drum, align the sleeve 7 with the drum connection of the external structure and insert the sleeve 7 into the connection. When the sleeve 7 is inserted into the connection, the snap-fit ​​spring piece 8 will be deformed, so that the sleeve 7 can enter the connection normally. After the sleeve 7 enters the connection, the reset of multiple snap-fit ​​spring pieces 8 will be against the inner wall of the connection, increasing the friction between the sleeve 7 and the inner wall of the connection, preventing the sleeve 7 from spinning at the connection. When it is necessary to extend the length of the roller, the air plug 10 is opened and gas is injected into the connecting air pipe 9, so that the gas enters the telescopic air bag 11 along the connecting air pipe 9, thereby expanding and stretching the telescopic air bag 11, pushing the insert 2 3 to slide on the insert 1 2, and the slide rail 12 will slide along the slide groove 13 to prevent the insert 2 3 from shifting when it is displaced. After the length adjustment is completed, the air plug 10 is plugged back into the air inlet of the connecting air pipe 9, and the resin jacket 14 of corresponding length is sleeved on the outer wall of the insert 1 2 and the insert 2 3.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
