[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The following is combined with Figure 1-4 The utility model is described in further detail.

[0029] Example 1

[0030] See also Figure 1-4, this embodiment provides a technical solution: a steering gear tie rod structure, including a cross bar body 1, a mounting block 2, a fixing portion 3 and a connecting rod 4. The cross bar body 1 is made of high-strength steel as a whole to prevent the cross bar body 1 from breaking during use. The mounting blocks 2 are fixed at both ends of the cross bar body 1. The mounting blocks 2 are connected to the cross bar body 1 by bolts, which is convenient for staff to disassemble. The fixing portion 3 is arranged above the mounting block 2. The fixing portion 3 has a fixing frame 301 fixed above the mounting block 2. The fixing frame 301 is connected to the mounting block 2 by welding to prevent the fixing frame 301 from separating from the mounting block 2. An inner frame is fixed inside the fixing frame 301 302, the inner frame 302 is connected to the fixed frame 301 by welding to ensure the stability of the overall structure. The outer wall of the inner frame 302 is provided with a threaded groove, and the threaded groove of the inner frame 302 is threadedly connected with a threaded ring 303. The threaded ring 303 can rotate to perform vertical movement under the influence of the thread. The threaded ring 303 is rotatably connected to a push ring 304 above the threaded ring 303. The vertical movement of the threaded ring 303 can drive the push ring 304 to perform vertical movement. The upper surface of the push ring 304 is hinged with a connecting rod 305. The vertical movement of the push ring 304 can drive the connecting rod 305 to rotate. The top of the connecting rod 305 is hinged with a fixed block 306. The rotation of the connecting rod 305 can drive the fixed block 306 to perform water movement. The fixing block 306 is slidably connected to the inner frame 302, the inner frame 302 is provided with a square hole, and the fixing block 306 is embedded in the square hole of the inner frame 302. The connecting rod 4 is arranged above the fixing frame 301, and the bottom of the connecting rod 4 is embedded in the inner frame 302, and the fixing block 306 is slidably connected to the bottom of the connecting rod 4. The connecting rod 4 is fixed by the fixing block 306 to ensure the stability of the connecting rod 4 after being fixed. A limiting rod 307 is fixed on the inner wall of the fixing frame 301, and the limiting rod 307 is slidably connected to the fixing block 306. The fixing block 306 is limited by the limiting rod 307 to ensure the stability of the fixing block 306 during the horizontal movement. A limiting protrusion 308 is fixed on the inner wall, and the limiting protrusion 308 is slidably connected to the push ring 304. The limiting protrusion 308 limits the push ring 304 to prevent the push ring 304 from rotating together with the threaded ring 303. The inner wall of the push ring 304 is slidably connected to the inner frame 302, and the push ring 304 is slidably connected to the inner wall of the fixed frame 301. The fixed frame 301 and the inner frame 302 limit the push ring 304 to ensure the stability of the push ring 304 during vertical movement. The threaded ring 303 is made of stainless steel, and six groups of circular holes are opened on the outer wall of the threaded ring 303 to facilitate the staff to insert tools into the circular holes to drive the threaded ring 303 to rotate.

[0031] Example 2

[0032] See also Figure 1-4The fixing portion 3 also has a protective ring 310 arranged at the bottom of the fixing frame 301. The protective ring 310 is made of magnetic stainless steel to prevent the protective ring 310 from rusting. A sliding ring 309 is fixed on the inner wall of the top of the protective ring 310. The protective ring 310 is connected to the sliding ring 309 by welding. The movement of the protective ring 310 can drive the sliding ring 309 to move, and the sliding ring 309 is slidably connected to the outer wall of the fixing frame 301. A magnetic block 311 is fixed on the bottom of the threaded ring 303, and the magnetic block 311 is connected to the outer wall of the fixing frame 301. The inner wall of the protective ring 310 is in contact with the protective ring 310, and the protective ring 310 can be fixed by the magnetic block 311 to prevent the protective ring 310 from shaking during the placement process. The protective ring 310 protects the threaded ring 303 to prevent the threaded ring 303 from rotating due to external collisions. There are two groups of magnetic blocks 311, and both groups of magnetic blocks 311 are in contact with the inner wall of the protective ring 310. The two groups of magnetic blocks 311 can better fix the protective ring 310 to prevent the protective ring 310 from loosening.

[0033] Working principle: First, when the connection rod 4 needs to be released, slide the protective ring 310 upward to separate it from the magnetic block 311. While keeping the protective ring 310 pulled upward, manually rotate it or use a tool to insert the hole of the threaded ring 303 to rotate it. Since the threaded ring 303 is threadedly connected to the outer wall of the inner frame 302, the threaded ring 303 rotates and gradually moves downward under the influence of the thread. The vertical movement of the threaded ring 303 drives the push ring 304 to perform the same movement.

[0034] Secondly, since the push ring 304 is hinged to the bottom end of the connecting rod 305, and the top end of the connecting rod 305 is hinged to the fixed block 306, the vertical movement of the push ring 304 will drive the fixed block 306 to move horizontally under the action of the connecting rod 305. The fixed block 306 moves horizontally and separates from the bottom groove of the connecting rod 4. Then, the connecting rod 4 can be pulled upward to complete the disassembly.

[0035] Finally, when the connecting rod 4 needs to be installed, the bottom of the connecting rod 4 is inserted into the inner wall of the inner frame 302, and then the protective ring 310 is pulled upward again and the threaded ring 303 is rotated. The rotation of the threaded ring 303 will drive the push ring 304 to move upward. The upward movement of the push ring 304 will drive the fixing block 306 to move horizontally under the action of the connecting rod 305. The fixing block 306 moves horizontally and is inserted into the groove at the bottom of the connecting rod 4 to complete the fixation. Then the protective ring 310 is slid downward so that the threaded ring 303 is accommodated in the protective ring 310. The threaded ring 303 is protected by the protective ring 310 to prevent the threaded ring 303 from rotating due to external influences.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
