[0002] The raw materials, semi-finished products and finished products in the tire production process need to be frequently transported between various production links. The use of lightweight trolleys can make the transportation process easier and more efficient, while reducing the labor intensity of workers and improving work efficiency. The existing lightweight trolleys for tire production can basically meet daily use needs, but there are still some shortcomings that need to be improved.

[0003] Most of the lightweight tire production trolleys widely used on the market adopt a single cart design. When in use, the finished tires need to be moved to the trolley, but the placed tires cannot be quickly and effectively fixed. Once the trolley is bumped during transportation, the tires on the trolley are likely to fall off and roll around. For this reason, we propose a lightweight tire production trolley to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a lightweight trolley for tire production includes a trolley frame 1 and a roller 2 installed at the bottom of the trolley frame 1. A placement seat 3 is fixed at the lower end of the trolley frame 1, and two groups of placement grooves 4 are opened on the placement seat 3. A sleeve seat 5 is installed in the middle of the upper end of the trolley frame 1, and a servo motor 6 is installed at the rear end of the sleeve seat 5. A threaded rod 7 is rotatably connected inside the sleeve seat 5, and the output end of the servo motor 6 is connected to the end of the threaded rod 7. Guide grooves 8 are opened on both sides of the sleeve seat 5, and the threaded rod 7 is externally threaded. A threaded sleeve 9 is connected, and guide blocks 10 are fixed on both sides of the threaded sleeve 9. The two groups of guide blocks 10 are located in the guide grooves 8 on both sides of the sleeve 5. A cross bar 11 is fixed to the opposite end of the two groups of guide blocks 10. Through holes 12 are opened on the two groups of cross bars 11. Connecting rods 13 are movably inserted in the two groups of through holes 12. Clamps 14 are fixed to the bottom ends of the two groups of connecting rods 13. A handle 15 is fixed to the top of the two groups of connecting rods 13. The cross bars 11 are connected to the connecting rods 13 through height positioning components.

[0022] By installing a placement slot 4 at the bottom of the trolley frame 1, the tire to be transported can be placed in the two sets of seats 5 on the placement slot 4, and then a movable clamping plate 14 is installed in the placement slot 4. When a tire needs to be placed in the placement slot 4, the pull handle 15 can be pulled upward to allow the connecting rod 13 to drive the clamping plate 14 to move upward along the through hole 12 on the cross bar 11, so as to facilitate the placement of the tire in the placement slot 4 on the placement seat 3. When the tire is placed, the clamping plate 14 can be moved to the placement slot 4 on the placement seat 3, and then the servo motor 6 is started to allow the servo motor 6 to move upward. The servo motor 6 drives the threaded rod 7 in the sleeve seat 5 to rotate, so that the threaded sleeve 9 outside the threaded rod 7 can drive the two groups of cross bars 11 to move laterally under the guidance of the thread and the two groups of guide blocks 10, so that the two groups of clamping plates 14 can move laterally along the placement groove 4 on the placement seat 3 under the drive of the cross bar 11, so that the clamping plates 14 can move to the side of the tire in the placement groove 4, and the clamping plates 14 can squeeze and fix the tire in the placement groove 4, thereby effectively preventing the tire from accidentally falling off during the movement of the trolley frame 1, thereby improving the stability of the device during use.

[0023] In other embodiments, the height positioning assembly includes a positioning groove 16, a sliding sleeve 17, a slider 18, a positioning rod 19, a second pull handle 20 and a return spring 21. The two groups of connecting rods 13 are provided with positioning grooves 16 at both ends, and the two groups of crossbars 11 are fixed with sliding sleeves 17 at the side ends of the through holes 12. The two groups of sliding sleeves 17 are slidably connected with sliders 18. The two groups of sliders 18 are fixed with positioning rods 19 at the opposite ends. The two groups of positioning rods 19 can be inserted into the positioning groove 16 on the connecting rod 13 at the opposite ends. The two groups of sliders 18 are fixed with second pull handles 20 at the tops, and the two groups of sliding sleeves 17 are provided with return springs 21.

[0024] By installing a laterally movable positioning rod 19 on the cross bar 11, when the height of the splint 14 needs to be adjusted, the handle 20 can be pushed laterally, so that the handle 20 drives the slider 18 to slide along the sliding sleeve 17, so that the positioning rod 19 leaves the positioning groove 16 on the connecting rod 13, and the slider 18 squeezes the return spring 21 to shrink the return spring 21, and then the handle 15 can be pulled to allow the connecting rod 13 to drive the splint 14 to move along the through hole 12. When the splint 14 moves to a suitable position, the force on the handle 20 can be released, and the return spring 21 releases its elastic force to push the slider 18 to slide along the sliding sleeve 17, so that the slider 18 drives the positioning rod 19 to be quickly inserted into the positioning groove 16 at the corresponding position on the connecting rod 13, so that the slider 18 can quickly form a movable limiting effect on the connecting rod 13, thereby quickly adjusting the height of the splint 14, thereby improving the convenience of using the device.

[0025] In other embodiments, rubber gaskets are glued to the outer walls of the two sets of clamps 14;

[0026] This design can effectively prevent the outer wall of the clamping plate 14 from wearing the tire surface.

[0027] In other embodiments, the outer wall of the guide block 10 is fully fitted with the inner wall of the guide groove 8 on the sleeve 5, and the guide block 10 is slidably connected with the guide groove 8;

[0028] Through this design, the two groups of guide blocks 10 can slide smoothly and quickly along the guide grooves 8 on both sides of the sleeve 5, thereby improving the stability of the device when in use.

[0029] In other embodiments, the outer wall of the handle 15 is provided with anti-slip textures;

[0030] Through this design, the friction between the handle 15 and the user's hand can be effectively increased, making it easier to pull the handle 15 upward.

[0031] In other embodiments, the width of the positioning rod 19 is the same as the width of the positioning slot 16 on the through hole 12;

[0032] With this design, when the positioning rod 19 is inserted into the positioning groove 16 on the connecting rod 13 , it can effectively prevent the positioning rod 19 from shaking in the positioning groove 16 , so that the positioning rod 19 forms a stable limiting effect on the connecting rod 13 .

[0033] In other embodiments, the two ends of the return spring 21 are respectively connected to the outer wall of the slider 18 and the inner wall of the sleeve 17, and the slider 18 is elastically connected to the inner wall of the sleeve 17 through the return spring 21;

[0034] With this design, the two groups of return springs 21 can exert elastic forces in opposite directions on the two groups of sliders 18 , so that the two groups of sliders 18 can drive the positioning rod 19 to quickly insert into the positioning groove 16 on the connecting rod 13 .

[0035] The electrical components mentioned in this article are all conventionally known devices.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
