AI Technical Summary
The existing groove wires are easily loose when the nuts and bolts are poorly matched or the tightening torque is insufficient. The nuts may be loose when subjected to external forces, resulting in the clamping plate being unable to clamp the wire, and the stability of use is poor.
A trench clamp for steel strands is designed. By setting screw heads, L-shaped rods, external tooth ring sheets, internal teeth and other structures at the connection between the screw and the nut, the nut is restricted by the meshing connection between the extension rod and the sleeve. The wire retardation rotates and increases stability through threaded connections between the studs and the nuts.
It effectively prevents the nut from retiring, enhances the stability of the groove clamp, avoids the occurrence of loosening, and improves the firmness during use.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] like Figure 1-4 As shown, a parallel groove wire clamp for steel strands comprises a lower clamping plate 1, an upper clamping plate 2 is arranged above the lower clamping plate 1, rod grooves 3 are cut at both ends of the lower clamping plate 1 and the upper clamping plate 2, stoppers 5 are fixed at both ends of the bottom of the lower clamping plate 1 located at the rod groove 3, screws 61 are inserted between the perpendicular rod grooves 3, screw heads 62 are arranged at one end of the screw 61 located at the bottom of the lower clamping plate 1, gaskets 7 are sleeved on the outer walls of one end of the screw 61 passing through the two rod grooves 3, nuts 8 are threadedly connected to the outer walls of one end of the screw 61 passing through the gasket 7, and the nuts 8 are close to each other. An L-shaped rod 9 is welded to one end, a stud 4 is welded to the top of the upper clamping plate 2 between the rod grooves 3, two outer toothed ring pieces 10 are sleeved on the outer wall of the bottom end of the stud 4, an extension rod 11 is fixed to the end of the outer toothed ring pieces 10 away from each other, a sleeve 12 is fixed to the end of the extension rod 11 away from the outer toothed ring pieces 10, a nut 16 is threadedly connected to the outer wall of the top of the stud 4, a pressure ring 13 is sleeved on the outer wall of the stud 4 below the nut 16, arc plates 14 are fixed to the two ends of the bottom of the pressure ring 13, and inner teeth 15 are provided on the inner wall of the arc plate 14.
[0021] Specifically, the pressure ring 13 is located above the two outer toothed ring pieces 10, the arc plates 14 are respectively located at the front and rear ends between the two outer toothed ring pieces 10, the inner teeth 15 are respectively meshed with the outer walls at the front and rear ends of the outer toothed ring pieces 10, and the length distance from the top to the bottom of the inner teeth 15 is greater than the sum of the distances from the top to the bottom of the two outer toothed ring pieces 10, thereby preventing the outer toothed ring pieces 10 from rotating.
[0022] Specifically, the inner diameter of the sleeve 12 matches the outer diameter of the L-shaped rod 9, and the sleeve 12 is respectively sleeved on the outer wall of the L-shaped rod 9. If the outer gear ring 10 does not rotate, the sleeve 12 cannot rotate either. If the sleeve 12 does not rotate, the nut 8 connected to one end of the L-shaped rod 9 cannot be rotated to withdraw the wire.
[0023] Specifically, the screw head 62 is located between the two stoppers 5 , and the side walls of the screw head 62 are in contact with the side close to the stoppers 5 , so as to prevent the screw head 62 from rotating.
