The connecting channel 100 is coaxial with the cylinder, so that the thickness of the material from the inner wall of the connecting channel 100 to the outer wall of the cylinder is kept consistent, and the structural strength of the columnar body 1 is ensured.
The lower part of the columnar body 1 comprises an elastic expansion structure 2, and the elastic expansion structure 2 can be made of elastic materials such as rubber and the like, so that the subsequent outer diameter of the elastic expansion structure 2 is conveniently increased. The connecting channel 100 is communicated to the elastic expansion structure 2, an expansion structure is arranged at the elastic expansion structure 2 in the connecting channel 100, the expansion structure can be a contraction structure with the inner diameter smaller than that of the connecting channel 100, and when the connecting stud is located at the expansion structure, the connecting stud drives the expansion structure to move outwards, so that the elastic expansion structure 2 is driven to expand.
Before installing the wall body plug-in, the wall body plug-in is required to be drilled at a preset position of the wall surface, and then the wall body plug-in is inserted into the wall surface hole. When the wall plug-in is installed, the elastic expansion structure 2 at the lower part of the columnar body 1 is firstly inserted into the wall surface opening, and then the columnar body 1 is completely or partially inserted into the wall surface opening. Then inserting a connecting stud of the background wallboard into the connecting channel 100, when the connecting stud continuously contacts and presses the expansion structure in the connecting channel 100, pushing the expansion structure and the elastic expansion structure 2 to expand towards the wall surface opening, and fixing the wall body plug-in the wall surface opening by matching the outer wall of the elastic expansion structure 2 with the wall surface opening, wherein the wall body plug-in is abutted with the wall surface opening, so that the gap between the wall body plug-in and the wall surface opening is reduced, and the contact area and the connection strength between the expansion sleeve and the wall body are increased; in addition, the wall plug-in can assist the connecting stud to be well driven into the wall, the inner wall of the connecting channel 100 is flat compared with the wall surface opening, the contact area and the connecting strength of the wall plug-in and the connecting stud are improved, and the construction efficiency is also improved.
In some implementations of the present embodiment, the expansion feature is an expansion protrusion 201 protruding toward the connection channel 100.
In the above embodiment, the expansion structure is the expansion protrusion 201 protruding toward the connection channel 100, and the inner diameter of the connection channel 100 is reduced at the expansion protrusion 201, so that when the connection stud abuts against the expansion protrusion 201 and is continuously inserted into the connection channel 100, the connection stud drives the expansion structure to move outwards, and further drives the elastic expansion structure 2 to expand.
In some implementations of this embodiment, the longitudinal section of the expansion lobe 201 is semi-circular.
In the above embodiment, the expansion protrusion 201 with a semicircular longitudinal section makes the edge transition of the expansion protrusion 201 smoother, and reduces the resistance when the connection stud abuts against the expansion protrusion 201 and continues to be inserted into the connection channel 100.

In some implementations of the present embodiment, the elastically expandable structure 2 is provided with an axially extending expansion slit 203.
In the above embodiment, the expansion slit 203 penetrates through the connection passage 100 and the elastic expansion structure 2, and in general, the larger the expansion slit 203 is, the higher the degree of deformation of the elastic expansion structure 2 is, because the expansion slit 203 affects the tensile strength (i.e., the ability to resist external force) of the surrounding structure. When the elastic expansion structure 2 expands outwards, the area of the expansion gap 203 correspondingly increases, so that the maximum expansion degree of the elastic expansion structure 2 can be improved.
In some implementations of the present embodiment, the expansion protrusions 201 are a plurality of, and the plurality of expansion protrusions 201 are circumferentially disposed along the inner wall of the elastic expansion structure 2.
In the above embodiment, if the expansion slit 203 is only a single one, the elastic expansion structures 2 on both sides of the expansion slit 203 are less stressed when the elastic expansion structures 2 are expanded, the elastic expansion structures 2 on other parts are more stressed, and the material around the expansion slit 203 is easily pulled. The expansion gaps 203 are multiple, and the expansion gaps 203 are circumferentially arranged along the outer wall of the columnar body 1, so that uniformity of the expansion gaps 203 is increased, uniformity of stress of the elastic expansion structure 2 is also improved, and service life of the elastic expansion structure 2 is guaranteed.
In some implementations of this embodiment, the outer peripheral side of the elastically expandable structure 2 is provided with fixation barbs 202.

When the hole is formed in the preset position of the wall surface, vibration generated by the hole can possibly cause larger pits to be formed in the inner wall of the hole of the wall surface, and when the elastic expansion structure 2 expands, the fixing protruding thorns 202 can be placed in the pits in the inner wall of the hole of the wall surface, so that the contact area between the elastic expansion structure 2 and the hole of the wall surface is increased by the fixing protruding thorns 202.
In some implementations of this embodiment, the outer diameter of the elastically expandable structure 2 increases gradually from top to bottom.
In the above embodiment, the outer diameter of the expanded and expanded lower end of the elastic expansion structure 2 is larger, so as to improve the abutting effect of the elastic expansion structure 2 and the wall surface opening.
In some implementations of this embodiment, the upper end of the columnar body 1 is provided with a locating collar 3, the outer diameter of the locating collar 3 being greater than the outer diameter of the columnar body 1.
In the above embodiment, the positioning collar 3 can be limited when the columnar body 1 is driven into the wall surface opening, so that the positioning collar 3 at the upper end of the columnar body 1 is positioned outside the wall surface, and the subsequent manual disassembly of the wall body plug-in is facilitated.
