[0022] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments in the following description are only as examples, and other obvious modifications can be conceived by those skilled in the art.

[0023] Referring to Figures 1-4 As shown in FIG. 1, a kind of anti-loose electrically operated adjusting steering machine bushing includes bushing body 1 and the abutting mechanism for positioning bushing body 1 firmly in steering gear mounting hole;

[0024] The abutting mechanism includes several movable channels 2 around the bottom surface of bushing body 1, and several accommodating grooves are longitudinally formed on the outer wall of bushing body 1 and communicated with movable channels 2, abutting block 3 is slidably arranged in accommodating grooves, and novel pressure transmission part is arranged in movable channels 2 and matched with abutting block 3.

[0025] Through the arrangement of abutting mechanism, when bushing body 1 is installed in steering gear mounting hole, novel pressure transmission part is previously deeply arranged in mounting hole and contacted with the inner wall of bottom end of mounting hole, and then novel pressure transmission part is continuously compressed in movable channels 2 and extrudes abutting block 3 in the process of putting bushing body 1 into mounting hole, so that abutting block 3 is extended outward from accommodating grooves and contacted with the inner wall of mounting hole, so that the stability of bushing installed on steering gear is ensured by the contact effect between abutting block 3 and the inner wall of mounting hole.

[0026] Further, referring to Figure 3 As shown in FIG. 2, it is worth noting that novel pressure transmission part includes slide 4 vertically sliding in the inner side of movable channel 2, and pressing block 5 below abutting block 3 is vertically fixed on one side wall of slide 4, and the opposite side of pressing block 5 corresponding to abutting block 3 above is provided with inverted bevel angle.

[0027] When bushing body 1 is put into steering gear mounting hole, slide 4 is contacted with the inner wall of bottom end of mounting hole and shrunk to the inner side of movable channel 2, so that pressing block 5 is contacted with abutting block 3 along with the movement of slide 4, so that abutting block 3 is extruded and withdrawn from accommodating grooves.

[0028] However, in actual application scenario, a certain amount of lubricating oil is usually stored in the mounting hole of steering gear, and this common working condition brings serious challenge to the technical solution, because the existence of lubricating oil can greatly weaken the friction between abutting block 3 and the inner wall of mounting hole, so that the contact effect between them is greatly reduced, and finally the stability of bushing body 1 installation cannot be effectively guaranteed.

[0029] Therefore, referring to Figure 3 And Figure 4 As shown in FIG. 3 and FIG. 4, it is worth noting that wall wiping assembly is arranged at the bottom of slide 4.

[0030] The wall wiping assembly comprises a connecting block 6 vertically fixed outside the sliding seat 4 and a sponge 7 glued to the end of the connecting block 6, and the side of the sponge 7 away from the connecting block 6 is at the same level as the outer wall of the movable channel 2;

[0031] Through the arrangement of the wall wiping assembly, during the process of deepening the sliding seat 4 into the installation hole, the sponge 7 in the wiping assembly can vertically wipe the inner wall of the installation hole at the same time, thereby cleaning the lubricating oil on the inner wall of the installation hole, so that when the abutting block 3 contacts the inner wall of the bushing main body 1, direct contact can be formed between the two, thereby improving the contact effect;

[0032] Further, as shown in Figure 3 , it is worth noting that the bottom end surface of the bushing main body 1 is also provided with a relief gap 12 corresponding to the connecting block 6;

[0033] Through the arrangement of the relief gap 12, when the bushing main body 1 is completely embedded in the steering gear installation hole, the sponge 7 and the connecting block 6 can be completely accommodated inside the relief gap 12, thereby reasonably storing the wall wiping assembly, so that the bushing main body 1 can be in good contact with the inner wall of the deep part of the installation hole and be installed in place.

[0034] Further, as shown in Figure 3 and Figure 4 , it is worth noting that the bottom end of the sliding seat 4 is open, and a limiting rail assembly is arranged in the open end of the sliding seat 4;

[0035] The limiting rail assembly comprises a limiting support column 8 vertically sliding in the inside of the sliding seat 4 and a magnetic block 9 fixed to the bottom end of the limiting support column 8;

[0036] Through the arrangement of the limiting rail assembly, when the sliding seat 4 is deepened into the installation hole, the magnetic block 9 first contacts the inner wall of the installation hole and forms a stable magnetic attraction with the metal steering gear shell, and the limiting support column 8 is vertically fixed. After that, the sliding seat 4 can only vertically slide along the rod body of the limiting support column 8, and the wiping track of the sponge 7 is accurately limited, which can make the wiping plate uniformly, comprehensively and efficiently clean the lubricating oil on the inner wall of the bushing main body 1, and ensure that the abutting block 3 and the inner wall of the installation hole achieve ideal direct contact, thereby enhancing the stability of the bushing installation.

[0037] Further, as shown in Figure 4 , it is worth noting that the top end of the limiting support column 8 is fixed with a limiting ring 11, the rod body of the limiting support column 8 is slidingly sleeved with a fixed sleeve 10, the outer wall of the fixed sleeve 10 is fixed with the inner wall of the open end of the sliding seat 4, and the limiting ring 11 is located above the fixed sleeve 10;

[0038] Through the arrangement of the limiting ring 11 and the fixed sleeve 10, the limiting support column 8 can be effectively limited, preventing the limiting support column 8 from directly separating from the inside of the sliding seat 4 and affecting the use effect.

[0039] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection required by the present application is defined by the appended claims and their equivalents.
