Description

Technical Field

[0001] This utility model relates to the field of tire repair tools, and in particular to an auxiliary device for automobile tire repair. Background Technology

[0002] During car tire repair, there are significant safety hazards when repair personnel work on tires with rim lock rings. On the one hand, the steel rim may pop out and cause injury due to improper operation; on the other hand, in manual tire removal scenarios, when the tire changer is out of service or when dealing with tires that are too large for the changer to handle, and during tire repair, there is a lack of reliable tire securing methods, affecting the safety and efficiency of the repair work. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an auxiliary device for automobile tire repair, which solves the problem of the lack of reliable tire fixing methods in the existing tire repair process, thus affecting the safety of the repair work.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] An auxiliary device for automobile tire repair includes a cross-shaped base, a support column installed on the center line of the cross-shaped base, the tire being fitted onto the support column, a first support frame and a second support frame installed opposite to each other on both sides of the cross-shaped base, a first limiting plate hinged to the top of the first support frame, and a second limiting plate hinged to the top of the second support frame, with semi-circular slots opened at the free ends of the first and second limiting plates, and the first and second limiting plates being engaged with the support column through the slots after rotating relative to each other towards the support column.

[0006] Furthermore, an adjusting column is rotatably mounted on the support column, the tire is mounted on the adjusting column, and there is an interference fit between the tire and the adjusting column. A limiting bolt is provided on the upper outer wall of the adjusting column, and the threaded end of the limiting bolt abuts against the surface of the support column.

[0007] Furthermore, the free end of the first limiting plate is provided with a snap-fit ​​protrusion, and the free end of the second limiting plate is provided with a snap-fit ​​groove, and the snap-fit ​​protrusion and the snap-fit ​​groove are connected in cooperation.

[0008] Furthermore, the outer wall of the adjusting column is provided with external threads, on which a first limiting ring, a second limiting ring and a third limiting ring are fitted. The first limiting ring limits the tire on the adjusting column. After the second limiting ring and the third limiting ring are tightened relative to each other, they clamp and limit the free ends of the first limiting plate and the second limiting plate.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model utilizes a cross-shaped base, a support column, an adjusting column, and a limiting plate in combination. The tire is mounted on the adjusting column, which is fixed relative to the support column. The first and second limiting plates are engaged with the support column through slots, and their free ends are connected by engaging protrusions and engaging slots. A limiting ring further clamps and limits the free ends of the limiting plates. This multi-structure coordinated fixing method can securely restrain the tire, greatly reducing the possibility of the steel rim popping out due to improper operation, effectively preventing injuries, and solving the safety hazards existing in current maintenance practices.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] An auxiliary device for automobile tire repair includes a cross-shaped base 1, a support column 4 installed on the center line of the cross-shaped base 1, a tire 9 mounted on the support column 4, a first support frame 2 and a second support frame 6 installed opposite to each other on both sides of the cross-shaped base 1, a first limiting plate 3 hinged to the top of the first support frame 2, a second limiting plate 5 hinged to the top of the second support frame 6, and semi-circular slots 14 opened opposite to each other on the free ends of the first limiting plate 3 and the second limiting plate 5. After the first limiting plate 3 and the second limiting plate 5 rotate relative to each other towards the support column 4, they engage the support column 4 through the slots 14.

[0017] An adjusting column 10 is rotatably mounted on the support column 4. The tire 9 is mounted on the adjusting column 10, and there is an interference fit between the tire 9 and the adjusting column 10. A limiting bolt is provided on the upper outer wall of the adjusting column 10, and the threaded end of the limiting bolt abuts against the surface of the support column 4.

[0018] The free end of the first limiting plate 3 is provided with a snap-fit ​​protrusion 8, and the free end of the second limiting plate 5 is provided with a snap-fit ​​groove 7. The snap-fit ​​protrusion 8 and the snap-fit ​​groove 7 are connected in cooperation.

[0019] The outer wall of the adjusting column 10 is provided with external threads, on which a first limiting ring 11, a second limiting ring 12 and a third limiting ring 13 are fitted. The first limiting ring 11 limits the tire 9 on the adjusting column 10. After the second limiting ring 12 and the third limiting ring 13 are tightened relative to each other, they clamp and limit the free ends of the first limiting plate 3 and the second limiting plate 5.

[0020] When using:

[0021] Place the cross base 1 stably on the ground, put the tire 9 that needs to be repaired on the adjusting column 10, and use the interference fit between the tire 9 and the adjusting column 10 to initially fix the tire 9. Depending on the repair situation on site, the tire 9 can be rotated to the corresponding position at any time. Then, the adjusting column 10 is limited by the limiting bolt at the top of the adjusting column 10. The first limiting ring 11 is installed on the adjusting column 10 to limit the tire 9 and prevent the tire 9 from moving axially on the adjusting column 10.

[0022] Rotate the first limiting plate 3 and the second limiting plate 5 so that their free ends rotate towards the support column 4. When the semi-circular slots 14 on the first limiting plate 3 and the second limiting plate 5 are aligned with the support column 4, continue rotating so that the slots 14 engage with the support column 4. At the same time, the engaging protrusion 8 on the free end of the first limiting plate 3 engages with the engaging groove 7 on the free end of the second limiting plate 5 to further enhance the limiting effect. Finally, install the second limiting ring 12 and the third limiting ring 13 on the adjusting column 10 and tighten them relative to each other to clamp and limit the free ends of the first limiting plate 3 and the second limiting plate 5.

[0023] After tire 9 is secured, maintenance personnel can perform various maintenance operations on tire 9. When it needs to be used in conjunction with a tire changer, this device can be placed on the working surface of the tire changer for use, which enhances the practicality of on-site operations. Maintenance personnel can carry out tire change, tire repair and other work more conveniently and efficiently, improve the efficiency of maintenance work, and make up for the shortcomings of existing maintenance methods in terms of the flexibility and applicability of fixing methods.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
