[0018] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

[0019] In the description of the present invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence relationship of the indicated technical features.

[0021] In the description of the present utility model, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0022] Please refer to Figures 1-3 , the present utility model provides a technical solution: a wear-resistant threaded sliding sleeve, including a threaded sliding sleeve 2, a guide block 1 is fixedly connected to the upper end of the threaded sliding sleeve 2, through grooves 6 are formed on the sides of the guide block 1 and the threaded sliding sleeve 2, a limiting strip 7 is slidably connected to the inner wall of the through groove 6, a limiting block 8 is fixedly connected to the inner wall of the through groove 6, the limiting strip 7 is slidably connected with the limiting block 8, the limiting strip 7 is in an "L" shape, and the materials of the guide block 1 and the threaded sliding sleeve 2 are both stainless steel, and the surfaces of the guide block 1 and the threaded sliding sleeve 2 are both chrome-plated.

[0023] The design of the through groove 6 makes the adjustment and maintenance of the threaded sliding sleeve 2 more convenient. Precise limit settings can be made according to actual needs, and replacement or repair can be carried out when necessary. Chrome plating the surfaces of the guide block 1 and the threaded sliding sleeve 2 forms a hard and wear-resistant protective layer on the surfaces of the guide block 1 and the threaded sliding sleeve 2, thereby extending their service life and improving the wear resistance of the guide block 1 and the threaded sliding sleeve 2.

[0024] A first groove 3 is formed on the inner surface of the guide block 1, a limiting ring 4 is slidably connected to the inner wall of the first groove 3, a second groove 9 is formed on the surface of the limiting strip 7, and the limiting block 8 is in contact with the second groove 9.

[0025] It is convenient to use bolts to limit the limiting strip 7 by the limiting ring 4 and the limiting block 8, which is convenient to improve the stability of the limiting strip 7. By fixing the limiting strip 7, the stability of related components in the predetermined position can be ensured, preventing displacement due to vibration or external force, and improving the stability of the connection.

[0026] Fiber strips 5 are formed on the outer surface of the threaded sliding sleeve 2, and internal threads 10 are formed on the inner surface of the threaded sliding sleeve 2.

The thread structure helps to disperse the stress between the connecting components, reduce the damage caused by stress concentration, and improve the durability of the threaded sleeve 2 and the connecting components. The tight fit of the internal and external threads helps to prevent the connecting components from loosening or falling off during use, improving the reliability of the connection.

[0028] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present utility model.
