DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0023] A sealing device for tire retreading includes a base 1, a hanger 2 is fixedly connected inside the base 1, a turntable 3 is symmetrically rotatably connected on the inner side wall of the hanger 2, a transverse axis 4 is fixedly connected inside the turntable 3, two groups of movable sleeves 5 are slidably connected outside the transverse axis 4, and the two groups of movable sleeves 5 are rotatably connected outside the support plate 6, and one end of the transverse axis 4 away from the turntable 3 is fixedly connected to a limiting plate 7. To retread a waste tire, it is first necessary to solve the hole in the tire, by placing the tire on the outside of the support plate 6, and according to the inner diameter of the tire, to open the support plate 6, so that the support plate 6 can complete the contact with the inside of the tire and complete the clamping and fixing of the tire.

[0024] For further information, see Figure 1 and Figure 2 In this embodiment, a cross plate 8 is fixedly connected to the outside of the horizontal axis 4 and to one side close to the turntable 3. A groove 9 is opened inside the cross plate 8. The support plate 6 extends to the outside of the groove 9. The end of the support plate 6 close to the limiting piece 7 is designed with an inclined structure. The end of the support plate 6 away from the limiting piece 7 is fixedly connected with a blocking block 10. The support plate 6 is connected to the groove 9 through the blocking block 10. The support plate 6 is moved inside the groove 9 by moving the support plate 6. The support plate 6 is limited by the design of the groove 9 to achieve linear motion. In addition, the design of the blocking block 10 effectively prevents the support plate 6 from leaving the preset position inside the groove 9.

[0025] For further information, see Figure 1 and Figure 2In this embodiment, a first spring 11 is provided on the fixed sleeve outside the transverse axis 4 and located on the side away from the two groups of movable sleeves 5. The outside of the movable sleeve 5 is rotatably connected with a linkage rod 12. The end of the linkage rod 12 away from the movable sleeve 5 is rotatably connected with the support plate 6. By pressing the support plate 6, the linkage rod 12 is driven to contract, thereby realizing the movement of the movable sleeve 5 outside the transverse axis 4, and driving the first spring 11 to contract, so that the inner sleeve of the outer tire is arranged on the outside of the support plate 6, so that it is reset by the expansion and contraction energy storage of the first spring 11, driving the movable sleeve 5 to reset, and fixing the outer tire.

[0026] For further information, see Figure 1 and Figure 2 In this embodiment, an elastic sealing membrane 13 is fixedly connected between the support plates 6, and the interior of the horizontal axis 4 is designed as an open structure. An air pipe 14 is fixedly connected to one end of the horizontal axis 4 close to the turntable 3, and the air pipe 14 extends to the outside of the hanger 2. The air pipe 14 is connected to the hanger 2 in a rotating manner. When the support plates 6 are unfolded, the elastic sealing membrane 13 is straightened to increase the sealing between the support plates 6. By connecting the output end of the air pump to the air pipe 14 and rotating it toward the outer tire, the leakage position can be known at the first time.

[0027] For further information, see Figure 1 and Figure 3 In this embodiment, the top of the inner side of the hanger 2 is fixedly connected with an insertion shaft 15, and the outside of the insertion shaft 15 is symmetrically slidably connected with a slider 16. The outside of the insertion shaft 15 and the side away from the two groups of sliders 16 are sleeved with a second spring 17. The bottom of the slider 16 is rotatably connected with a swing rod 18, and the end of the swing rod 18 away from the slider 16 is rotatably connected with a receiving seat 19. The outside of the receiving seat 19 is symmetrically fixedly connected with a support rod 20, and a roller 21 is rotatably connected between the support rods 20. The surface of the roller 21 is provided with air holes. By rotating the outer tire, the heights of outer tires of different sizes are also different, thereby squeezing the roller 21, so that the support rod 20 is unfolded, and then the slider 16 will slide on the outside of the insertion shaft 15, so as to adjust the height of the roller 21, and the sealant flows out through the air hole and is smeared on the surface of the outer tire. Finally, the slider 16 is reset by the second spring 17.

[0028] In this embodiment, the implementation scenario is specifically as follows: by pressing the support plate 6, the linkage rod 12 is driven to contract, so that the movable sleeve 5 is moved outside the horizontal axis 4, and the first spring 11 is driven to contract, and the support plate 6 is limited by the design of the groove 9 to achieve its linear movement. The design of the blocking block 10 effectively prevents the support plate 6 from being separated from the preset position inside the groove 9, and drives the first spring 11 to contract, so that the inner sleeve of the outer tire is set on the outside of the support plate 6, so that the first spring 11 is retracted to store energy for resetting, driving the movable sleeve 5 to reset and the support plate 6 to reset. The plate 6 is unfolded to fix the outer tire, and the elastic sealing membrane 13 is straightened through the support plate 6 to increase the sealing between the support plates 6. By connecting the output end of the air pump with the air pipe 14 and rotating it towards the outer tire, the leakage position can be known at the first time. The heights of outer tires of different sizes are also different, so the roller 21 is squeezed, so that the support rod 20 is unfolded, and then the slider 16 will slide on the outside of the plug shaft 15, so as to adjust the height of the roller 21, and the sealant flows out through the air vent and is smeared on the surface of the outer tire, and finally the slider 16 is reset by the second spring 17.
