the end face of the other end of the threaded column is provided with a cross groove, and the side face of the threaded column is provided with a thread in the same direction as the screw; and the first nut and the second nut are sequentially in threaded connection on the threaded column.
Further, the other end edge of the threaded column has a chamfered slope.
Further, the threaded post has a diameter larger than the screw.
Furthermore, a first washer and a second washer are further sleeved on the threaded column, and the first washer and the second washer are arranged between the first nut and the second nut; a space for fixing the mounting section bar is formed between the first gasket and the second gasket.
The screw thread sleeve is hollow in the axis, an internal thread is arranged on the inner wall of the screw thread sleeve, and an external thread is arranged on the outer wall of the screw thread sleeve; the outer wall of the extension screw is provided with external threads; the inner diameter of the threaded sleeve is matched with the outer diameters of the threaded column and the extension screw rod, and two ends of the threaded sleeve are respectively sleeved on the threaded column and the extension screw rod and are in threaded connection with the threaded column and the extension screw rod.
The expansion screw for flexibly mounting the section bar, provided by the utility model, has the advantages that the other end of the screw is provided with the threaded column, so that an adjustable mounting space is provided for the section bar. The profile is clamped in the middle through the first nut and the second nut, the fixed position of the profile on the threaded column can be adjusted, and then the distance between the profile and the wall surface is adjusted, so that the profile is more convenient and flexible to mount, and can be widely applied to various different engineering scenes. Compared with the expansion screw in the prior art, the expansion screw can further reduce the gap between the plane material and the wall surface, so that the plane material is more firmly installed, and the structural stability is improved.

Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and fig. 2, an expansion screw for flexibly mounting a profile provided by an embodiment of the present invention includes an expansion sleeve 1, a screw main body 2, a first nut 31 and a second nut 32, where the screw main body 2 includes a screw 21 and a threaded column 22, one end of the screw 21 is fixedly connected with one end of the threaded column 22, a radially protruding limit table 20 is provided at a connection between the screw 21 and the threaded column 22, and the limit table 20 divides the screw 21 and the threaded column 22 into two sections; the expansion sleeve 1 is sleeved on the screw 21;
the end face of the other end of the threaded column 22 is provided with a cross groove, and the side face of the threaded column 22 is provided with a thread in the same direction as the screw 21; the first nut 31 and the second nut 32 are in turn screwed onto the threaded post 22.
Further, the other end (the end having the cross-shaped groove) edge of the threaded post 22 has a chamfered slope. The chamfer slope can provide a guiding function when the first nut 31 and the second nut 32 are installed, so that the installation process is smoother.
Further, the threaded post 22 has a larger diameter than the screw 21.
Further, the threaded column 22 is further sleeved with a first washer 41 and a second washer 42, and the first washer 41 and the second washer 42 are disposed between the first nut 31 and the second nut 32. A space for fixing the mounting profile is formed between the first washer 41 and the second washer 42.
The expansion screw for flexibly mounting the section bar, provided by the utility model, has the advantages that the other end of the screw is provided with the threaded column, so that an adjustable mounting space is provided for the section bar. The profile is clamped in the middle through the first nut and the second nut, the fixed position of the profile on the threaded column can be adjusted, and then the distance between the profile and the wall surface is adjusted, so that the profile is more convenient and flexible to mount, and can be widely applied to various different engineering scenes.
Specifically, when the expansion sleeve is used, the expansion sleeve is firstly inserted into a pre-drilled mounting hole on a wall surface, and then one end of the screw 21 of the screw main body 2 is inserted into the middle of the expansion sleeve 1. The screw 21 can be screwed into the expansion sleeve 1 by a screwdriver through the cross groove on the end surface of the threaded column 22, so that the screw body 2 is fastened on the wall surface; alternatively, the first nut 31 may be screwed into the threaded column 22, and then the wrench may be used to continue to screw the first nut 31 to screw the screw 21 into the expansion shell 1. During screwing the screw 21, the limiting table 20 plays a limiting role, so that the threaded column 22 is exposed outside the wall surface.
After the screw 21 is in place, the first nut 31, the first washer 41, the profile, the second washer 42 and the second nut 32 are mounted in sequence on the threaded post 22. By adjusting the first nut 31 and the second nut 32, the position of the profile on the threaded column 22 can be adjusted, and the distance between the profile and the wall surface can be adjusted.
