The insertion of one end of the limiting rod 10103 into the inner side of the limiting hole 10002 improves the assembly accuracy between the first anchor plate 100 and the second anchor plate 101, thereby enhancing the stability of the entire anchor structure.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5One end of the limiting rod 10103 is tapered. The top of the second anchor plate 101 has a second insertion hole 10102. A second locking bolt 106 is installed inside the second insertion hole 10102. The top and bottom ends of the first anchor plate 100 both have second threaded holes 10003. The second locking bolt 106 and the second threaded hole 10003 engage with each other via threads. The inner diameter of the first anchor hole 10001 is the same as the inner diameter of the second anchor hole 10101. The outer diameter of the extrusion cylinder 105 is larger than the inner diameter of the first anchor hole 10001. The tapered shape of one end of the limiting rod 10103 makes it easier to insert into the limiting hole 10002, reducing installation difficulty and improving installation efficiency. The second locking bolt 106 is installed inside the second insertion hole 10102. Multiple connection safeguards are provided between the first anchor plate 100 and the second anchor plate 101, further enhancing the reliability of the connection between them, effectively dispersing stress, preventing connection failure due to excessive local stress, and improving the stability and safety of the anchor under complex stress conditions. The fact that the inner diameter of the first anchor hole 10001 is the same as the inner diameter of the second anchor hole 10101 ensures the smooth passage of the steel strand 102 through the first anchor plate 100 and the second anchor plate 101. The fact that the outer diameter of the extrusion cylinder 105 is larger than the inner diameter of the first anchor hole 10001 prevents the extrusion cylinder 105 from entering the anchor hole, thereby ensuring that the extrusion cylinder 105 can effectively extrude and fix the end of the steel strand 102 on the outside of the anchor, preventing the steel strand 102 from coming out of the anchor and improving the anchoring effect.

[0033] Specifically, the working principle of this non-tensioned end compression anchor is as follows: During use, the first anchor plate 100 and the second anchor plate 101 cooperate, and steel strands 102 are placed in their corresponding anchor holes. This provides stable positioning and anchoring for the steel strands 102. The connecting mechanism 1103 firmly connects the first anchor plate 100 and the second anchor plate 101, ensuring the integrity and stability of the entire anchor structure while facilitating user disassembly and maintenance. The compression spring 104 and compression cylinder 105 enhance the fixing effect on the end of the steel strands 102, preventing loosening or displacement during use. This ensures the reliability of the anchoring. The connecting plate 10301 and the first locking bolt 10303 facilitate installation and disassembly while ensuring a strong connection. This allows for easy assembly and maintenance of the anchor under different usage environments or installation requirements. Welding one side of the connecting plate 10301 to the outer side of the first anchor plate 100 further enhances the connection strength between the connecting mechanism 103 and the first anchor plate 100. Inserting one end of the limiting rod 10103 into the inner side of the limiting hole 10002 improves the assembly accuracy between the first anchor plate 100 and the second anchor plate 101, thus enhancing the anchoring reliability. The stability of the entire anchor structure is enhanced by the tapered shape of one end of the limiting rod 10103, which facilitates insertion into the limiting hole 10002, reducing installation difficulty and improving efficiency. A second locking bolt 106 is installed inside the second insertion hole 10102, providing multiple connection guarantees between the first anchor plate 100 and the second anchor plate 101, further enhancing the reliability of the connection, effectively dispersing stress, preventing connection failure due to excessive local stress, and improving the stability and safety of the anchor under complex stress conditions. The inner diameter of the first anchor hole 10001... The inner diameter of the first anchor hole 10001 is the same as that of the second anchor hole 10101, ensuring the smooth passage of the steel strand 102 through the first anchor plate 100 and the second anchor plate 101. The outer diameter of the extrusion cylinder 105 is larger than the inner diameter of the first anchor hole 10001, preventing the extrusion cylinder 105 from entering the anchor hole. This ensures that the extrusion cylinder 105 can effectively extrude and fix the end of the steel strand 102 on the outside of the anchor, preventing the steel strand 102 from coming out of the anchor and improving the anchoring effect. This utility model can effectively realize the split structure of the anchor plate, which is convenient for the inspection and maintenance of the steel strand and has high practical value.
