[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0027] Reference Figs. 1-3 An embodiment provided by the utility model: a kind of steering machine speed reducer, including speed reducer body 1, connecting frame 4 is fixedly connected in speed reducer body 1 front side, connecting frame 4 front side is provided with connecting frame 5, bolt 6 is uniformly screw-connected in the inside four quarters of connecting frame 5, connecting frame 5 front side is provided with protection assembly, for protecting bolt 6, connecting frame 5 is fixedly connected with connecting frame 4 by bolt 6, speed reducer body 1 lower part left and right sides are fixedly connected with mounting block 2, mounting hole 3 is set in the front and rear sides of mounting block 2, protection assembly includes mounting sleeve 9, mounting sleeve 9 is slidingly connected in the outside of connecting frame 5, mounting sleeve 9 four quarters are fixedly connected with guard plate 10, baffle 7 is provided in the front side of guard plate 10, handle 8 is fixedly connected in the front side of baffle 7, baffle 7 is fixedly connected in the front side of bolt 6, bolt 6 is slidingly connected in the inside of guard plate 10.

[0028] By rotating handle 8, handle 8 drives baffle 7 to rotate, and then baffle 7 drives bolt 6 to rotate, so that bolt 6 is separated from connecting frame 4. At this time, the worker can pull connecting frame 5 to make it separate from connecting frame 4, so as to facilitate the repair and maintenance of steering machine speed reducer. After repair is completed, the worker can push connecting frame 5 to move it to the front side of connecting frame 4. Finally, by rotating handle 8 again, handle 8 drives baffle 7 to rotate, so that baffle 7 drives bolt 6 to reconnect connecting frame 5 and connecting frame 4. This design not only facilitates the repair and maintenance of steering machine speed reducer, but also effectively protects bolt 6 through baffle 7 and guard plate 10, thereby significantly improving the service life of bolt 6 and ensuring the long-term stable operation of the equipment.

[0029] Reference Figs. 1-3The mounting sleeve 9 is made of engineering plastic material, the protective plate 10 and the baffle 7 are made of glass fiber reinforced plastic material, and the handle 8 is made of aluminum alloy material.

[0030] In order to improve the performance and service life of each component of the equipment, different high-performance materials are used for optimization design. First, the mounting sleeve 9 is made of engineering plastic material. This material has excellent wear resistance, which can effectively prolong the durability of the mounting sleeve 9 when it is in contact with other components during long-term use, reduce wear and tear, and improve the stability and reliability of the overall equipment. Second, the protective plate 10 and the baffle 7 are made of glass fiber reinforced plastic GF-PP material. This composite material has excellent impact resistance and durability, which can effectively disperse energy when facing external impact force, reduce the risk of damage, and ensure the continuous and stable operation of the equipment in harsh working environments. In addition, in order to ensure the structural strength of the handle 8, aluminum alloy material is selected. Aluminum alloy has high strength and good corrosion resistance, which can prevent the handle 8 from deforming or being damaged when subjected to external force, thereby prolonging the service life. In order to improve the comfort and slip resistance of the handle 8, a plastic coating is added to the surface of the aluminum alloy. This coating not only provides a better grip to prevent slipping during use, but also has good slip resistance, improving the safety and comfort of the user during operation. Through the reasonable application of multiple materials, the performance of each component has been significantly improved, thereby improving the durability, safety and user experience of the entire equipment.

[0031] Working principle: when the steering machine reducer needs to be maintained and repaired, the handle 8 is rotated to drive the baffle 7 to rotate, the baffle 7 drives the bolt 6 to rotate to make the bolt 6 disengage from the connecting frame 4, then the connecting frame 5 is pulled to make the connecting frame 5 disengage from the connecting frame 4, so that the worker can maintain and repair the steering machine reducer. After the maintenance is completed, the connecting frame 5 is pushed to move to the front side of the connecting frame 4, and finally the handle 8 is rotated to drive the baffle 7 to rotate, the baffle 7 drives the bolt 6 to connect the connecting frame 5 and the connecting frame 4, thereby realizing the steering machine reducer which is convenient to maintain and repair, and the bolt 6 is protected by the baffle 7 and the protective plate 10, thereby improving the service life of the bolt 6.
