Description

Technical Field

[0001] The utility model relates to the technical field of connecting rods, in particular to a connecting rod with high rigidity. Background Art

[0002] Connecting rods are usually used in mechanical systems to connect two parts or mechanisms and enable the mechanism or system to achieve specific functions by transmitting force and motion. In mechanical transmission systems, connecting rods can connect two rotating or translating parts to achieve transmission effects by transmitting force and motion. For example, the connecting rod in a car engine is a strong connecting rod that connects the crankshaft and the piston to achieve the operation of the engine.

[0003] For some existing connecting rods, the two connecting rod covers are connected by bolts and fixing plates during installation. However, after long-term use, the bolts in this connection method may cause a certain gap between them due to friction with the connection points or the influence of vibration and shock. When used again, the bolts may become loose, reducing their strength or directly affecting the vehicle. Utility Model Content

[0022] 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.

[0023] Example 1

[0024] like Figure 1 - Figure 3 As shown, the utility model provides a technical solution: a connecting rod with high rigidity, comprising: a reinforcement mechanism 1, the reinforcement mechanism 1 comprising a first connecting rod cover 11, retaining rings 12 are arranged on both sides of the first connecting rod cover 11, first fixing plates 13 are arranged on both sides of the surface of the first connecting rod cover 11, a second connecting rod cover 14 is arranged near the inner side of the first connecting rod cover 11, bearing bush baffles 15 are arranged on the inner walls of the first connecting rod cover 11 and the second connecting rod cover 14, second fixing plates 16 are arranged on both sides of the surface of the second connecting rod cover 14, the inner wall of the threaded groove opened in the second fixing plate 16 is provided with a connecting mechanism 2, fixing tubes 17 are arranged on the inner walls of the clamping grooves opened on both sides of the second connecting rod cover 14, elastic members 18 are arranged on the inner walls of the two fixing tubes 17, push rods 19 are arranged on the other side of the two elastic members 18, clamping blocks 110 are arranged on the other ends of the two push rods 19, and pressing members 111 are arranged on the other side of the two clamping blocks 110.

[0025] In this embodiment, the first connecting rod cover 11 is fixedly connected with a snap ring 12 on both sides, and the grooves defined by the two snap rings 12 are fixedly engaged with the corresponding protrusions of the block 110, and the first connecting rod cover 11 and the inner wall of the second connecting rod are connected with a bearing bushing baffle 15; when installing, the user can first align the two snap rings 12 with the grooves defined by the two sides of the second connecting rod cover 14, and then push the first connecting rod cover 11 to fix the snap ring 12 and the block 110. After the snap ring 12 is engaged with the block 110, the first connecting rod cover 11 and the second connecting rod cover 14 will also be limited. It is more convenient for the user to fix it again through the fixing piece 21 later. The fixing method of the clamping ring 12 and the clamping block 110 can not only effectively avoid the problem of gap between the bolt and the connection due to friction during long-term use, which in turn causes the loosening of the bolt to affect the use of the connecting rod, thereby improving the stability and reliability of the connection. The fixing method of the clamping ring 12 and the clamping block 110, on the basis of limiting, and then fixing the first connecting rod cover 11 and the second connecting rod cover 14 for a second time through the fixing piece 21, can also increase the strength of the connection, improve the load-bearing capacity, and avoid failures and damages caused only by loose bolts.

[0026] Compared with the traditional method of fixing with only a single bolt, this method can avoid the gap between the bolt and the connection due to friction during long-term use, which may cause the bolt to loosen and affect the use of the connecting rod.

[0027] The first connecting rod cover 11 is fixedly connected with the first fixing plate 13 on both sides of the surface, and the second connecting rod cover 14 is fixedly connected with the second connecting rod cover 14 on both sides of the surface; when the user engages the clamping ring 12 with the clamping block 110 to limit the first connecting rod cover 11 and the second connecting rod cover 14, the fixing piece 21 can be rotated to thread the fixing piece 21 with the first fixing plate 13 and the second fixing plate 16, so as to increase the strength of the first connecting rod cover 11 and the second connecting rod cover 14. By using the fixing piece 21 to threadably fix the fixing plate, the rigidity and stability of the connecting piece can be increased, so that the connection between the first connecting rod cover 11 and the second connecting rod cover 14 is more secure.

[0028] The inner walls of the slots opened on both sides of the second connecting rod cover 14 are fixedly connected with fixing tubes 17, the inner walls of the two fixing tubes 17 are connected with elastic members 18, the other sides of the two elastic members 18 are provided with push rods 19, the other ends of the two push rods 19 are provided with clamping blocks 110, the other sides of the two clamping blocks 110 are provided with pressing members 111, and the other side surfaces of the two pressing members 111 are respectively fixedly connected with the slots opened on both sides of the second connecting rod cover 14; when the user needs to disassemble the first connecting rod cover 11 and the second connecting rod cover 14 for maintenance and other operations, the fixing member 21 can be rotated in the opposite direction first to remove the fixing member 21 from the first fixing plate 13 and the fixing plate 14. The second fixing plate 16 is unloaded from the threaded groove, and then the pressing member 111 is pressed. When the pressing member 111 is pressed, the clamping block 110 and the push rod 19 are pushed to move synchronously. When the push rod 19 moves, the elastic member 18 is squeezed. When the elastic member 18 is squeezed, it will shrink to the other side. When the elastic member 18 shrinks, the clamping block 110 will also move and release the limit from the clamping ring 12. The method of pressing the pressing member 111 can not only make the disassembly operation more convenient, but also avoid the traditional method of fixing with multiple bolts to increase its strength, and other complicated steps such as using multiple tools when disassembling. This method improves the efficiency and convenience of disassembly and can be more convenient for users.

[0029] Example 2

[0030] like Figure 1 - Figure 4 As shown, the connecting mechanism 2 includes a fixing member 21, and there are two fixing members 21. The inner walls of the threaded grooves opened in the two first fixing plates 13 and the second fixing plates 16 are threadedly connected with the fixing members 21, and the one end surfaces of the two fixing members 21 are in contact with gaskets 22, and the one end surfaces of the two fixing members 21 are threadedly connected with nuts 23.

[0031] In this embodiment, by using a threaded connection, friction is formed between the fixing member 21 and the inner wall of the thread groove, which not only increases the friction resistance of the connection, improves the tightness of the connection, and enhances the stability and reliability of the connection, but the use of the gasket 22 can also disperse the load at the connection, so that the load is transmitted over a larger surface area, reducing stress concentration at the connection, and reducing the risk of damage and failure caused by stress concentration.

[0032] Working principle:

[0033] like Figure 1 - Figure 4As shown, when installing, the user can first align the two snap rings 12 with the slots opened on both sides of the second connecting rod cover 14 respectively, and then push the first connecting rod cover 11 to fix the snap ring 12 and the block 110. When the snap ring 12 is engaged with the block 110, the first connecting rod cover 11 and the second connecting rod cover 14 will also be limited. When they are limited, it will be more convenient for the user to fix them again through the fixing member 21. When the user engages the snap ring 12 with the block 110 to limit the first connecting rod cover 11 and the second connecting rod cover 14, the fixing member 21 can be rotated to thread the fixing member 21 and the first fixing plate 13 and the second fixing plate 16, and finally the nut 23 can be installed, so as to increase the strength of the first connecting rod cover 11 and the second connecting rod cover 14.

[0034] When the user needs to disassemble the first connecting rod cover 11 and the second connecting rod cover 14 for maintenance or other operations, the user can first rotate the fixing member 21 in the opposite direction to remove the fixing member 21 from the threaded groove formed by the first fixing plate 13 and the second fixing plate 16, and then press the pressing member 111. When the pressing member 111 is pressed, the clamping block 110 and the push rod 19 are pushed to move synchronously. When the push rod 19 moves, the elastic member 18 is squeezed. When the elastic member 18 is squeezed, it will shrink toward the other side. When the elastic member 18 shrinks, the clamping block 110 will also move to release the limit of the snap ring 12, and the user can separate the first connecting rod cover 11 from the second connecting rod cover 14.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
