[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution for a connecting rod structure of an automobile:

[0021] according to Figure 1-4As shown, it includes a connecting rod body 1, which is composed of a first connecting part 2, a second connecting part 3 and an intermediate stretching part 4. The first connecting part 2 and the second connecting part 3 are both provided with a socket 10 at the end, the intermediate stretching part 4 is inserted and connected between the two sockets 10, and a fixing component is arranged between the intermediate stretching part 4 and the first connecting part 2 and the second connecting part 3.

[0022] Specifically, the connecting rod body 1 can adjust the length of the connecting rod body 1 according to needs through the cooperation of the first connecting part 2, the second connecting part 3 and the intermediate stretching part 4, and can adapt to the use of changes within a certain length range, thereby effectively improving the practicality of the connecting rod body 1.

[0023] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixing assembly includes a tooth block 8 and a bolt 5. The bolts 5 are threadedly connected to both sides of the inner wall of the socket 10. The tooth block 8 is rotatably connected to the end of the bolt 5. Tooth grooves 11 are provided at both corners on both sides of the middle stretching part 4. The tooth block 8 is meshed with the tooth grooves 11.

[0024] Specifically, the bolt 5 pushes the tooth block 8 to move, so that the tooth block 8 is engaged with and separated from the tooth groove 11, which facilitates the fixation of the middle stretching part 4.

[0025] Both ends of the middle stretching portion 4 are fixed with fixing blocks 9 , and the sizes of the two fixing blocks 9 are the same as the inner diameter of the insertion hole 10 , and the insertion hole 10 is convex.

[0026] Specifically, by disposing the fixing block 9, the separation of the intermediate stretching portion 4 from the first connecting portion 2 and the second connecting portion 3 during the stretching process is reduced.

[0027] An assembly hole is provided in the middle of the first connection part 2, and multiple arc grooves 7 are provided at equal distances on both sides of the inner wall of the assembly hole. Solid lubricating blocks 12 are embedded in the multiple arc grooves 7. Specifically, the solid lubricating blocks 12 can lubricate the connection part.

[0029] Reinforcement ribs are fixedly provided on both sides of the first connection part 2 and the second connection part 3. Specifically, the structural strength of the first connection part 2 and the second connection part 3 is increased by providing the reinforcement ribs.

[0030] Working principle: The utility model provides a connecting rod structure of an automobile. When using the connecting rod body 1, firstly, the length of the connecting rod body 1 is adjusted according to demand, and the bolts 5 on both sides of the first connecting part 2 and the second connecting part 3 are manually loosened to separate the tooth block 8 from the tooth groove 11. Then, the first connecting part 2 and the second connecting part 3 are manually pulled to both sides. When pulled to the set length, the bolts 5 are manually turned again to push the tooth block 8 to move through the bolts 5 to engage the tooth block 8 with the tooth groove 11 to complete the length adjustment of the connecting rod body 1. Before the connecting rod body 1 is assembled with the connecting shaft, the solid lubricating block 12 is nested in the arc groove 7, so that the friction between the connecting rod body 1 and the connecting shaft is reduced during the rotation of the connecting rod body 1, thereby improving the practicality of the connecting rod body 1.
