DETAILED DESCRIPTION
[0021] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0022] Example:
[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:
[0024] The top of the operating table 1 is symmetrically fixedly connected to the bracket 2, and the top of the inner side of the bracket 2 is rotatably connected to the first connecting shaft 3. The inner side of the bracket 2 and the lower side of the first connecting shaft 3 are rotatably connected to the second connecting shaft 4. The first connecting shaft 3 and the outer side of the second connecting shaft 4 are fixedly connected to the half gear 5. The half gear 5 is provided with two groups, and the two groups of half gears 5 are adapted for use. The outer side of the half gear 5 is fixedly connected to the first linkage rod 6. The end of the first linkage rod 6 away from the half gear 5 is rotatably connected to the second linkage rod 7, and the end of the second linkage rod 7 away from the first linkage rod 6 is rotatably connected to the extrusion plate 8. When it is necessary to spray the inside of the tire, the tire is placed on the top of the operating table 1 and the half gear 5 is toggled to achieve meshing between the half gears 5 and mutual rotation, thereby driving the first linkage rod 6 and the second linkage rod 7 to expand and be in a parallel state, thereby driving the two groups of extrusion plates 8 to approach each other and limit the tire.
[0025] For further information, see Figure 1 and Figure 2In this embodiment, a mounting bracket 9 is fixedly connected to the side away from the extrusion plate 8, and the second linkage rod 7 is rotatably connected to the extrusion plate 8 through the mounting bracket 9. The side close to the extrusion plate 8 is provided with anti-slip grooves, and the anti-slip grooves are distributed at equal intervals. Through the design of the mounting bracket 9, the second linkage rod 7 moves more smoothly, and the anti-slip grooves effectively increase the friction between the extrusion plate 8 and the tire, thereby further enhancing the limiting effect on the tire.
[0026] For further information, see Figure 1 and Figure 2 In this embodiment, a square groove 10 is formed in the middle of the extrusion plate 8, and a lower pressure plate 11 is slidably connected to the inside of the square groove 10. A spring 12 is fixedly connected to the bottom of the lower pressure plate 11. When the extrusion plate 8 contacts the tire, the lower pressure plate 11 is pulled upward to expand the spring 12. When the tire is limited, the lower pressure plate 11 is released, so that the spring 12 drives the lower pressure plate 11 to return to its original position, thereby limiting the top of the tire.
[0027] For further information, see Figure 1 and Figure 2 In this embodiment, one end of the first connecting shaft 3 extending to the outside of the bracket 2 is fixedly connected to a half worm gear 13, the bottom of the half worm gear 13 is meshed with a worm 14, and the outer rotation of the worm 14 is connected to a fixed frame 15. By connecting one end of the worm 14 to the driving motor, the worm 14 rotates and meshes with the half worm gear 13, thereby driving the half worm gear 13 to rotate, thereby driving the first connecting shaft 3 to rotate with the half worm gear 13.
[0028] For further information, see Figure 1 、 Figure 3 and Figure 4 In this embodiment, a chassis 16 is fixedly connected to the middle of the top of the operating platform 1, a motor is fixedly connected to the middle of the top of the chassis 16, and support frames 17 are symmetrically fixedly connected to the top of the chassis 16. Telescopic rods 18 are fixedly connected between the support frames 17, and a ring 19 is fixedly connected to the top of the telescopic rod 18. By arranging the outer tire on the outside of the chassis 16 and starting the telescopic rod 18, the height of the ring 19 is adjusted. The design of the support frame 17 effectively lifts the ring 19 when it is not in use.
[0029] For further information, see Figure 1 、 Figure 3 and Figure 4In this embodiment, an annular groove 20 is provided inside the circular ring 19, and the output end of the motor is fixedly connected to the vertical shaft 21, and the top of the vertical shaft 21 is fixedly connected to the connecting sleeve 22. The internal rotation of the connecting sleeve 22 is connected to the plug shaft 23, and one end of the plug shaft 23 is fixedly connected to the steering rod 24, and the steering rod 24 is adapted for use with the annular groove 20. The side of the plug shaft 23 away from the steering rod 24 is fixedly connected to the spray gun 25, and the spraying operation is completed on the inside of the outer tire by the spray gun 25. When the height of the outer tire is too high, the circular ring 19 is pressed down by the telescopic rod 18, so that the annular groove 20 presses down the steering rod 24, thereby driving the plug shaft 23 to rotate, so that the spray gun 25 completes the angle offset and tilts upward, which is adapted to outer tires of different heights. The vertical shaft 21 is driven by the motor to rotate, so that the spray gun 25 completes the rotational motion.
[0030] In this embodiment, the implementation scenario is specifically as follows: by arranging the outer tire on the outside of the chassis 16, by connecting one end of the worm 14 to the drive motor, the worm 14 is rotated and meshed with the half worm gear 13, thereby driving the half worm gear 13 to rotate, thereby driving the first connecting shaft 3 to rotate with the half worm gear 13, thereby achieving meshing between the half gears 5 and rotating with each other, thereby driving the first linkage rod 6 and the second linkage rod 7 to expand and be in a parallel state, thereby driving the two sets of extrusion plates 8 to approach each other, limiting the outer tire, and by pulling the lower pressure plate 11 upward, Thereby, the spring 12 is expanded. When the outer tire is limited, the lower pressure plate 11 is released, so that the spring 12 drives the lower pressure plate 11 to return to its original position, thereby limiting the top of the outer tire, and the spraying operation is completed on the inside of the outer tire through the spray gun 25. When the height of the outer tire is too high, the telescopic rod 18 drives the ring 19 to press down, so that the annular groove 20 presses down the steering rod 24, thereby driving the plug shaft 23 to rotate, so that the spray gun 25 completes the angle offset and tilts upward to adapt to outer tires of different heights. The vertical shaft 21 is driven by the motor to rotate, so that the spray gun 25 completes the rotational movement.
[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
