[0027] An outer pipe 1 and an inner pipe 2, wherein the inner pipe 2 is sleeved inside the outer pipe 1;

[0028] A support and fixing assembly 4, wherein the support and fixing assembly 4 is arranged outside the outer pipe 1;

[0029] A reinforcement filling component 3 is arranged outside the outer pipe 1 and the inner pipe 2. The reinforcement filling component 3 includes an outer annular groove 3-1. The outer annular groove 3-1 is opened on the two end faces of the outer pipe 1. A fitting sleeve 3-2 is connected inside the outer annular groove 3-1. The surface of the fitting sleeve 3-2 is provided with a plurality of through holes 3-3. A pull rod 3-4 is inserted and connected inside the through holes 3-3. Both ends of the pull rod 3-4 are screwed with fastening nuts 3-5 by threads. A filling hole 3-6 is opened on the surface of the fitting sleeve 3-2. Threaded grooves 3-7 are opened at both ends of the surface of the inner pipe 2. A reinforcement plate 3-8 is screwed in the threaded groove 3-7. A notch 3-9 is opened on the surface of the reinforcement plate 3-8.

[0030] In this embodiment, in order to achieve the effect of firmly fixing the outer pipe 1 in the wall hole, a supporting and fixing component 4 is designed, and outer annular grooves 3-1 are provided at both ends of the outer pipe 1, and a fitting sleeve 3-2 is installed in the outer annular groove 3-1. The fitting sleeve 3-2 is used to fit on the wall surface to form a closed space between the outer pipe 1 and the wall, and a filling hole 3-6 is provided on the surface of the fitting sleeve 3-2. Filling material such as foam glue can be injected into the filling hole 3-6 to fill the internal space and improve the sealing effect, and a through hole 3-3 is provided on the surface of the fitting sleeve 3-2. A pull rod 3-4 can be connected between the through holes 3-3. The pull rod 3-4 has the effect of reinforcing the filler and is screwed and connected with a fastening nut 3-5 for fixing. Threaded grooves 3-7 are provided at both ends of the outer surface of the inner pipe 2, and a reinforcing plate 3-8 is screwed and connected in the threaded groove 3-7 to fix the inner pipe 2 in the outer pipe 1 without the inner pipe 2 coming out due to external pulling.

[0031] Furthermore, the support and fixing assembly 4 includes a plurality of threaded holes 4-1, the threaded holes 4-1 are opened on the inner surface of the outer pipe 1, a support screw 4-2 is screwed in the threaded hole 4-1, a fixing block 4-3 is arranged at the upper end of the support screw 4-2, and a screw cap 4-4 is arranged at the lower end of the support screw 4-2.

[0032] In this embodiment, in order to achieve the supporting and fixing effect between the external pipe 1 and the wall hole, a supporting and fixing component 4 is designed. Two threaded holes 4-1 are opened on the four opposite sides of the external pipe 1. A supporting screw 4-2 is screwed in the threaded hole 4-1. A fixing block 4-3 is arranged at the upper end of the supporting screw 4-2. The fixing block 4-3 is used to support in the wall hole and adjust the length of the supporting screw 4-2 at each position, and adjust the axial position of the external pipe 1. A screwing cap 4-4 is arranged at the lower end of the supporting screw 4-2, and the supporting screw 4-2 can be operated by screwing the screwing cap 4-4.

[0033] Furthermore, the surface of the fixing block 4 - 3 is an arc-shaped spherical surface structure.

[0034] In this embodiment, the spherical structural surface allows the fixing block 4 - 3 to be firmly supported in the wall hole, making it more stable.

[0035] Furthermore, a plurality of fastening screws 5 are connected between the fitting sleeve 3-2 and the docking groove.

[0036] In this embodiment, the fitting sleeve 3-2 and the docking groove are pre-fixed and connected by tightening the nut 3-5 to facilitate subsequent installation and adjustment.

[0037] Furthermore, sealing layers 6 are provided at both ends of the inner surface of the outer pipe 1 , and the sealing layer 6 is sealed and fitted to the surface of the inner pipe 2 .

[0039] Furthermore, there are two filling holes 3-6, which are distributed at two opposite ends of the surface of the fitting sleeve 3-2.

[0040] In this embodiment, by installing the filling holes 3 - 6 at two opposite positions, the filling foam glue can be distributed more evenly.

[0041] Furthermore, the maximum diameter of the fitting sleeve 3-2 is greater than the maximum extension height of the support screw 4-2 and the fixing block 4-3.

[0042] In this embodiment, the position supported by the fixing block 4-3 is the maximum diameter of the wall hole, and it is necessary to ensure that the fitting sleeve 3-2 is larger than its supporting position to ensure that the fitting sleeve 3-2 can cover the wall hole.

[0043] When installation is required, place the outer pipe 1 into the wall hole, then screw the support screw 4-2 by screwing the cap 4-4, support the fixing block 4-3 in the wall hole and adjust the axial position, then put the fitting sleeve 3-2 into the outer ring groove 3-1 at both ends, and then install the fastening screws 5 to fix it. After fixing the position, inject foam glue into the filling hole 3-6, then put in the inner pipe 2, adjust the length of both ends of the inner pipe 2, and then screw the reinforcement plate 3-8 into the threaded groove 3-7 until it fits on the surface of the fitting sleeve 3-2, finally pass the pull rod 3-4 through the through hole 3-3, and finally screw the fastening nut 3-5 to the pull rod 3-4 to connect.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
