Technical Field

[0001] This application relates to the field of tire repair technology, and more particularly to a tire repair device. Background Technology

[0002] Tires are an important component of a car, and their condition affects the car's speed, safety, and driving experience. The outer tire is in constant contact with the road surface and is also affected by debris on the road, such as nails, broken glass, and metal pieces, which often leads to localized damage and requires repair.

[0003] The tire repair device disclosed in the related technology is a fixed installation on the ground. It uses mechanical clamps to fix the tire, places the tire in a vertical position and fixes its bottom, and uses the relatively flat positions such as the tire sidewall and tread of the tire repair device for repair.

[0004] However, due to the excessive curve at the shoulder position of low aspect ratio tires, it is difficult to fix the repair material to the outside of the tire shoulder position using the tire repair device disclosed in the related technology, thereby ensuring the formation of a reliable tire and tread pattern. Utility Model Content

[0005] This application provides a tire repair device that solves the problem that existing tire repair devices struggle to completely adhere the repair material to the outer side of the tire shoulder, thereby improving the reliable adhesion of the repair material to the tire shoulder.

[0006] This application provides a tire repair device, including:

[0007] A support frame is provided with an inner cavity for accommodating the tire sidewall, and the support frame includes a first connecting part and a second connecting part, the first connecting part and the second connecting part being correspondingly provided;

[0008] A heating support block is fixedly connected to the first connecting part, and a fixing part for connecting the repair template is provided on one end face of the heating support block facing the second connecting part;

[0009] The lifting cylinder is fixedly connected to the second connecting part, and the piston rod of the lifting cylinder is arranged facing the side close to the heating support block.

[0010] In some embodiments, it also includes:

[0011] The lower fixing head is connected to one side of the piston rod of the lifting cylinder, and the end face area of ​​the lower fixing head away from the lifting cylinder is larger than the cross-sectional area of ​​the piston rod of the lifting cylinder.

[0012] In some embodiments, a rubber layer is connected to one end of the piston rod of the lower fixing head away from the lifting cylinder, and the cross-sectional area of ​​the rubber layer is larger than the end face area of ​​the lower fixing head.

[0013] In some embodiments, the end face of the rubber layer away from the lower fixing head is roughened.

[0014] In some embodiments, the heating block has a temperature measuring hole for accommodating a temperature sensor.

[0015] In some embodiments, at least two fixing blocks are fixedly connected to the outer wall of the heating support near the temperature measuring hole, and the fixing blocks have fixing grooves for connecting the fixing brackets of the temperature measuring sensor made of heat insulation material.

[0016] In some embodiments, the gap between the fixing groove and the cross section perpendicular to the outer ring direction of the temperature measuring hole gradually decreases.

[0017] In some embodiments, a through-hole weight-reducing groove is also provided on the side wall of the inner cavity of the support frame.

[0018] In some embodiments, the inner wall of the weight-reducing groove is configured as an arc-shaped surface.

[0019] In some embodiments, the support frame includes:

[0020] The first frame, the second frame, and the third frame are connected in sequence;

[0021] Wherein, the length direction of the first frame is parallel to the length direction of the third frame, and one end of the second frame is fixedly connected to the first frame, and the other end of the second frame is fixedly connected to the third frame. The first connecting part is disposed on the first frame, and the second connecting part is disposed on the third frame.

[0022] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0023] This embodiment of the application utilizes a support frame to connect the heating block and the lifting cylinder. During tire repair, the supplementary rubber material is first placed on the shoulder area of ​​the tire to be repaired, and then the corresponding repair template is attached to the outer wall of the tire. Simultaneously, the heating block is attached to the repair template, and then the piston rod of the lifting cylinder extends. The piston rod of the lifting cylinder, together with the heating block, fixes the repair template, the supplementary rubber material, and the tire. Finally, the heating surface of the heating block heats up, raising the temperature of the repair template, thereby achieving pressure vulcanization of the supplementary rubber material. This ensures that the repaired tire has a reliable shoulder arc surface and a complete tread pattern, facilitating reliable and convenient tire repair. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0033] This application provides a tire repair device, including:

[0034] The support frame 1 is provided with an inner cavity for accommodating the tire sidewall, and the support frame 1 includes a first connecting part 11 and a second connecting part 12, with the first connecting part 11 and the second connecting part 12 being provided correspondingly.

[0035] The heating support block 2 is fixedly connected to the first connecting part 11, and the end face of the heating support block 2 facing the second connecting part 12 is provided with a fixing part for connecting the repair template;

[0036] The lifting cylinder 3 is fixedly connected to the second connecting part 12, and the piston rod of the lifting cylinder 3 is arranged towards the side close to the heating support block 2.

[0037] For example, the support frame 1 can be implemented as a one-piece steel material, the support frame 1 is C-shaped, and the first connecting part 11 and the second connecting part 12 are both provided on the inner cavity side wall of the support frame 1. The heating block 2 can be implemented as an aluminum heating head with a heating tube; and the lifting cylinder 3 can be implemented as an SC40*100 small cylinder, which drives its piston rod to move through an external air source.

[0038] Using a support frame 1 to connect the heating block 2 and the lifting cylinder 3, during tire repair, the replenishing rubber is first placed on the shoulder of the tire to be repaired, and then the corresponding repair template is attached to the outer wall of the tire. At the same time, the heating block 2 is attached to the repair template, and then the piston rod of the lifting cylinder 3 extends. The piston rod of the lifting cylinder 3 and the heating block 2 work together to fix the repair template, the replenishing rubber, and the tire. Finally, the heating surface of the heating block 2 heats up, which increases the temperature of the repair template, thereby achieving pressure vulcanization of the replenishing rubber. This ensures that the repaired tire has a reliable shoulder arc surface and a complete tread pattern, making tire repair reliable and convenient.

[0039] Reference Figure 1 Optionally, the support frame 1 provided in this application embodiment includes: a first frame 13, a second frame 14 and a third frame 15 connected in sequence;

[0040] The length direction of the first frame 13 is parallel to the length direction of the third frame 15, and one end of the second frame 14 is fixedly connected to the first frame 13, and the other end of the second frame 14 is fixedly connected to the third frame 15. The first connecting part 11 is provided on the first frame 13, and the second connecting part 12 is provided on the third frame 15.

[0041] For example, the first frame 13, the second frame 14 and the third frame 15 are formed into a C shape by integral molding, which facilitates the fixing of the lifting cylinder 3 and the heating support block 2, and ensures the reliability of tire repair.

[0042] Reference Figure 2 In some embodiments, based on the tire repair apparatus disclosed in the above embodiments, the tire repair apparatus provided in this application further includes:

[0043] The lower fixing head 4 is connected to one side of the piston rod of the lifting cylinder 3, and the end face area of ​​the lower fixing head 4 away from the lifting cylinder 3 is larger than the cross-sectional area of ​​the piston rod of the lifting cylinder 3.

[0044] For example, the lower fixing head 4 can be made of steel or aluminum. The bottom end of the lower fixing head 4 is connected to the piston rod of the lifting cylinder 3 by means of a threaded connection. At the same time, the piston rod of the lifting cylinder 3 increases the contact area with the tire to be repaired through the lower fixing head 4, thereby ensuring that when the piston rod of the lifting cylinder 3 is extended, the lower fixing head 4 and the heating block 2 together form a structure for pressurizing and fixing the tire.

[0045] Reference Figure 3In some embodiments, in order to avoid the tire inner wall from being worn due to direct contact between the lower fixing head 4 and the tire inner wall, the tire repair device provided in this application has a rubber layer 5 connected to one end of the piston rod of the lower fixing head 4 away from the lifting cylinder 3. The cross-sectional area of ​​the rubber layer 5 is larger than the end face area of ​​the lower fixing head 4.

[0046] For example, the end face of the rubber layer 5 away from the lower fixing head 4 is roughened. The roughened surface can be obtained by engraving multiple grooves on the end face of the rubber layer 5 or by slightly polishing it with a grinding wheel.

[0047] Meanwhile, because the rubber layer 5 has a certain degree of elasticity, an inner cavity with an opening area smaller than the end face area of ​​the lower fixing head 4 and the same shape and size as the end face of the lower fixing head 4 is created on the rubber layer 5. The elasticity of the rubber layer 5 allows it to fit over the surface of the lower fixing head 4, thus preventing direct contact between the lower fixing head 4 and the inner wall of the tire, which could lead to wear on the tire's inner wall.

[0048] Reference Figure 4 and Figure 5 In order to facilitate operators to detect the operating temperature of the heating block 2, the tire repair device provided in this application embodiment has a temperature measuring hole 21 for accommodating a temperature sensor in the heating block 2.

[0049] In some embodiments, at least two fixing blocks 22 are fixedly connected to the outer wall of the heating support block 2 near the temperature measuring hole 21. The fixing blocks 22 have fixing grooves 221 for connecting the fixing brackets of the temperature measuring sensor made of heat insulation material.

[0050] For example, in this embodiment of the application, there are two fixing blocks 22, and the two fixing blocks 22 are spaced apart along the outer wall of the temperature measuring hole 21, and the fixing groove 221 is opened on the side of the fixing block 22 near the inner wall of the temperature measuring hole 21.

[0051] Optionally, the gap of the fixing groove 221 perpendicular to the cross section along the outer ring direction of the temperature measuring hole 21 gradually decreases, and the fixing groove 221 can be implemented as a right trapezoidal projection shape along the outer wall of the temperature measuring hole 21.

[0052] Based on the tire repair device disclosed in the above embodiments, the support frame 1 provided in this application also has a through-hole weight reduction groove on the side wall of the inner cavity.

[0053] For example, the inner wall of the weight-reducing groove is set as an arc-shaped surface.

[0054] By setting the weight-reducing groove on the support frame 1 as an arc surface, stress concentration on the surface of the support frame 1 due to the weight-reducing groove is avoided, thus ensuring the strength of the support frame 1 itself.

[0055] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.

[0056] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this application.
