DETAILED DESCRIPTION

[0021] The specific embodiments of the present application will be further described below with reference to the accompanying drawings. The same parts are denoted by the same reference numerals in the drawings. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" refer to the directions towards or away from the geometric center of a particular part.

[0022] In order to make the content of the present application more easily understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. The same parts are denoted by the same reference numerals.

[0023] The present embodiment provides a single-sealing cable anchor, which includes connecting ring one 1, connecting ring two 2, adjusting assembly 3, limiting assembly 4, protective steel strand 5, sealing assembly one 6, and sealing assembly two 7. Connecting ring one 1 and connecting ring two 2 serve as the main structure, and the relative position is adjusted by adjusting assembly 3 to adapt to the requirements of cables of different lengths. Limiting assembly 4 is used to ensure the stability after adjustment and prevent position deviation caused by external force. Protective steel strand 5 passes through the entire structure to provide additional strength support. Sealing assembly one 6 and sealing assembly two 7 together constitute a multiple sealing system to ensure that the inside of the anchor is not eroded by the external environment.

[0024] In this embodiment, the adjusting assembly 3 includes adjusting threaded sleeves 301 fixedly arranged on the inner walls of the first connecting ring 1 and the second connecting ring 2, and adjusting threaded rods 302 threadedly connected in the adjusting threaded sleeves 301. One end of each adjusting threaded rod 302 is matched with the adjusting threaded sleeve 301, and the other end is provided with an anchor body 303 for connecting the cable. In order to fix the adjusted position, locking nuts 304 and 305 are threadedly connected on the adjusting threaded rods 302 and located on the two sides of the adjusting threaded sleeves 301, respectively. By tightening the two nuts, the position of the adjusting threaded rods 302 can be effectively locked, and the stability of the anchor device is ensured.

[0025] In this embodiment, the limiting assembly 4 mainly consists of a limiting ring plate one 401 fixedly arranged on the outer wall of the adjusting threaded sleeve 301 and a limiting ring plate two 402 fixedly arranged on the outer wall of the anchor body 303. The limiting ring plate one 401 is provided with a limiting bolt 403 inserted therein, and the limiting bolt 403 passes through the limiting ring plate two 402 and is fixed by a limiting nut 404. This design not only limits the axial movement of the anchor body 303, but also further enhances the overall stability of the structure through the fastening effect of the bolt and the nut.

[0026] In this embodiment, the sealing assembly one 6 is used to provide effective sealing protection to prevent moisture, dust and other impurities from entering the inside of the anchor device. Specifically, the lower end surface of the anchor body 303 is provided with a sealing groove one 601, and the anchor bodies 303 are provided with a sealing protection sleeve 602. The sealing protection sleeve 602 is provided with sealing rubber rings one 603 at both ends, which are tightly inserted into the sealing groove one 601 to form the first sealing barrier. In addition, the sealing protection sleeve 602 is also provided with a plurality of uniformly arranged sealing holes 604, through which the protective steel strands 5 are inserted, which not only ensures the strength of the structure, but also avoids direct penetration of the sealing layer, reducing the risk of leakage.

[0027] In the embodiment, the sealing assembly two 7 comprises a sealing ring plate one 701 fixedly arranged on the outer wall of the sealing protective sleeve 602 and a sealing ring plate two 702 fixedly arranged on the anchor body 303. The upper end surface of the sealing ring plate one 701 is provided with a sealing groove two 703, and the lower surface of the sealing ring plate two 702 is provided with a sealing rubber ring two 704 which is tightly inserted into the sealing groove two 703 to form a second sealing barrier. In addition, the lower surface of the sealing ring plate two 702 is also fixedly provided with a plurality of sealing screws 705 arranged uniformly, and the sealing screws pass through the sealing ring plate one 701 and are fixed by a sealing nut 706. This design not only enhances the reliability of the sealing, but also further improves the stability of the structure through the fastening effect of the screw and the nut. The sealing rubber ring one 603 and the sealing rubber ring two 704 are made of high-elasticity rubber or polyurethane material. These materials have good elasticity, wear resistance and corrosion resistance, and can maintain stable sealing performance in various harsh environments, thereby prolonging the service life of the anchor.

[0028] The above is only a preferred embodiment of the utility model patent, and is not used to limit the utility model patent. Any modification, equivalent replacement and improvement within the spirit and principle of the utility model patent should be included in the protection scope of the utility model patent.
