Description

Technical Field

[0001] The utility model relates to the technical field of steel strands, in particular to a steel strand connector. Background Art

[0002] A steel strand connector is a device used to connect steel strands. Its main function is to firmly connect the steel strands, ensure the stability and reliability of the connection points, and prevent the steel strands from loosening or falling off due to excessive vibration and other reasons, thereby ensuring the safety and reliability of the connection.

[0003] The Chinese utility model patent with patent application number 202223613336.4 discloses a steel strand connector, including a sleeve and a wire clamping assembly arranged inside the sleeve. The wire inlet end of the sleeve is connected to a guide piece, and the guide piece has a through hole with a conical cross-section, which gradually expands from the inside to the outside. Although the utility model makes the threading of the steel strand more convenient by providing a guide piece, and the wire inlet end of the sleeve is wrapped and protected by the provided edge guard to prevent the wire inlet end of the sleeve from rusting, the guiding effect of the guide piece is only for a short distance. After the steel strand passes through the guide piece, it can no longer play a guiding role, and the steel strand may still get stuck. At the same time, the edge guard is only provided at one end of the sleeve, and rainwater can still easily enter the sleeve, causing the sleeve or the wire clamp to rust, thereby affecting the fixing effect of the steel strand.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figures 1 to 3The utility model provides a technical solution: a steel strand connector, comprising a sleeve 1, and two wire clamps 10 arranged inside the sleeve 1, a first sealing sleeve 3 is installed at one end of the sleeve 1, a tapered portion 4 is provided on the first sealing sleeve 3, the tapered portion 4 is used to guide the steel strand, so that one end of the steel strand is gathered and enters the groove 12, a guide head 17 is provided between the wire clamp 10 and the first sealing sleeve 3, the guide head 17 is used to guide and gather one end of the steel strand, so that the steel strand can pass through the sleeve 1 more easily, which is convenient for the staff to install, and a circular arc portion is provided on the side of the guide head 17 close to the wire clamp 10 13. A groove 12 is provided on one side of the guide head 17 close to the first sealing sleeve 3. A second sealing sleeve 5 is installed on the other end of the sleeve 1. The second sealing sleeve 5 and the first sealing sleeve 3 can seal the two ends of the sleeve 1 to prevent rainwater from entering the sleeve 1, causing the wire clamp 10 or the sleeve 1 to rust together with the steel strand, affecting the fixing effect of the steel strand. A through hole 11 is penetrated by the second sealing sleeve 5. The through hole 11 facilitates the steel strand to pass through the second sealing sleeve 5. A chamfer 7 is provided on the inner side of the second sealing sleeve 5. The chamfer 7 is used to guide the guide head 17, so that the guide head 17 is easier to align and pass through the through hole 11.

[0018] Among them, a spring 8 is installed between the second sealing sleeve 5 and the wire clamp 10. The spring 8 is used to push the wire clamp 10 so that the wire clamp 10 automatically resets, thereby clamping the steel strand. The spring 8 can also apply a thrust to the second sealing sleeve 5 so that the second sealing sleeve 5 is close to the sleeve 1 to improve the sealing effect of the second sealing sleeve 5. A groove 6 is provided at one end of the second sealing sleeve 5 close to the spring 8. The groove 6 is used to limit the spring 8 so that the spring 8 and the second sealing sleeve 5 will not be misaligned.

[0019] The inner wall of the sleeve 1 is integrally formed with a retracted portion 14 , and the outer side of the first sealing sleeve 3 is provided with a convex ring 18 , which cooperates with the convex ring 18 to restrict the first sealing sleeve 3 so that no movement occurs between the first sealing sleeve 3 and the sleeve 1 .

[0020] A positioning groove 15 is provided at one end of the sleeve 1, and a positioning rod 16 matching the positioning groove 15 is provided on the conical portion 4. The positioning groove 15 and the positioning rod 16 cooperate to limit the first sealing sleeve 3 so that the first sealing sleeve 3 and the sleeve 1 do not rotate.

[0021] The second sealing sleeve 5 and the first sealing sleeve 3 are both made of rubber, which has good sealing performance, good corrosion resistance and long service life.

[0022] Among them, a protrusion 9 is provided on the inner side of the wire clamp 10, and the protrusion 9 is used to increase the friction between the wire clamp 10 and the steel strand, so that the wire clamp 10 can clamp the steel strand more firmly. A convex edge 2 is provided on the outer side of the sleeve 1, and the convex edge 2 facilitates the clamping of the sleeve 1 with other parts.

[0023] Specifically, when in use, one end of the steel strand is inserted from the first sealing sleeve 3, and one end of the steel strand enters the groove 12 through the convergence of the tapered portion 4. The steel strand pushes the guide head 17 to move, and the guide head 17 pushes the two wire clamps 10 to move. The wire clamps 10 compress the spring 8, and the two wire clamps 10 gradually move to a larger position of the sleeve 1. The two wire clamps 10 will gradually separate until the guide head 17 can pass through the wire clamp 10. After the steel strand is guided by the guide head 17, it passes through the wire clamp 10 and the spring 8 in turn, and then passes through the outside of the sleeve 1 from the through hole 11. The second sealing sleeve 5 and the first sealing sleeve 3 are both close to the steel strand to seal and prevent rainwater from entering the sleeve 1.
