[0007] In the above technical solution, a plurality of screw holes cooperating with the screws are evenly distributed in the circumferential direction on the side wall of one end of the lock nut away from the back plate.
[0008] In the above technical solution, corresponding strip-shaped slots are respectively provided on both sides of the inner wall of the track slot, and a plurality of strip-shaped buckles are provided on the other end of the lock nut opposite to the screw hole. The buckles are inserted into the slot along the depth direction of the slot, and the buckles cooperate with the slot.
[0009] In the above technical solution, there are two buckles, which are symmetrically arranged along the lock nut.
[0010] In the above technical solution, the track groove as a whole is an inverted "U"-shaped structure with one side open and the other side closed, and the end of the lock nut where the buckle is located is close to the closed surface of the track groove.
[0011] In the above technical solution, the lock nut is provided with an inner diameter larger than the outer diameter of the wire tube.
[0012] In the above technical solution, there are two screw holes, which are symmetrically arranged along the lock nut.
[0013] In the above technical solution, the line connecting the two buckles is perpendicular to the line connecting the two screw holes.
[0014] The utility model track type lock nut fixing device has the following beneficial effects:
[0015] The utility model can solve the problem of wire pipe blockage caused by inadequate protection of the pipe mouth, and avoid the wire pipe being moved during the concrete pouring process, causing the wire pipe to be out of straightness or offset. The device can significantly improve the qualified rate of later pipe threading, reduce the rework costs caused by wire pipe blockage in the later stage, increase the aesthetics of secondary piping, and reduce the difficulty of secondary piping.

[0021] See also Figures 1 to 4 The utility model provides a track-type lock nut fixing device, comprising a strip-shaped back plate 1 and a lock nut 4 that can be coaxially inserted with the wire tube. In one or more embodiments, the lock nut 4 is provided with an inner diameter greater than the outer diameter of the wire tube (not shown in the figure), and one side of the back plate 1 is provided with a track groove 2 arranged along the length direction of the back plate 1, and the outer diameter of the lock nut 4 matches the inner walls on both sides of the track groove 2.
[0022] The side wall of one end of the lock nut 4 away from the back plate 1 is evenly distributed with a plurality of screw holes 5 cooperating with screws (not shown in the figure). In one or more embodiments, there are two screw holes 5 symmetrically arranged along the lock nut 4.
[0023] Corresponding strip-shaped slots 3 are respectively provided on both sides of the inner wall of the track slot 2, and a plurality of strip-shaped buckles 6 are provided at the other end of the lock nut 4 opposite to the screw hole 5. The buckles 6 are inserted into the slot 3 along the depth direction of the slot 3, and the buckles 6 cooperate with the slot 3. In one or more embodiments, there are two buckles 6, which are symmetrically arranged along the lock nut 4, and the connecting line of the two buckles 6 is perpendicular to the connecting line of the two screw holes 5.
[0024] The track groove 2 is an inverted "U"-shaped structure with one side open and the other side closed. The end of the lock nut 4 where the buckle 6 is located is close to the closed surface of the track groove 2.
[0025] The back plate 1 is provided with a track groove 2 along the length direction, and a clamping groove 3 is provided on both sides of the track. To ensure the convenience of construction, the back plate 1 should not be too long, and the length can be 200 to 500 mm.
