At the end, the coupling hole 213 of the pipe plug 21 is aligned with the second channel 122 of the inner pipe 12, and the stopper 211 is abutted against the end of the inner pipe 12, and then the bolts 216 are used respectively. After matching with a washer 217 , the second channel 122 and the coupling hole 213 are locked and fixed with the nut 215 in sequence from outside to inside, thereby installing the two abutting units 20 on the two inner tubes 12 The linear displacement state of the abutting column 22 is achieved through the cooperation of the inner tube 12 and the limiting member 23 in the square structure, so that the telescopic displacement of the abutting column 22 can be adjusted through the screwing of the adjusting nut 221 , so that the abutting portion 222 can push outward against the wall to achieve the purpose of fixing the support rod 10 between the two walls.

For the actual use state of its structure, please refer to Figure 2 in conjunction with Figures 7 and 8. Before the support rod 10 is used, the extension length of the inner tube 12 should be adjusted according to the distance between the two walls of the installation position. The two positioning rods 13 respectively pass through the positioning holes 111 of the outer tube 11 and the positioning holes 121 of the inner tube 12 in series for positioning, and then connect the two tightening nuts 132 and the two positioning rods from the bottom of the outer tube 11 13. Lock and fix to limit the length of the inner tube 12 protruding from the two ends of the outer tube 11, thereby obtaining the use length of the support rod 10. At this time, the abutting unit 20 of the outer end of the inner tube 12 Both of them contact the two walls with the abutting portion 222 of the abutting column 22, and finally the adjusting nut 221 is screwed. The abutting post 22 will not rotate with the adjusting nut 221 , but can only perform a telescopic motion of linear displacement, and then push the abutting post 22 outward and insert the annular insert 223 of the abutting portion 222 In the wall, accordingly the support rod 10 is tightly fixed between the two walls, and the first and second channels 112 and 122 connected to one side of the outer tube 11 and the inner tube 12 can be used to set up a plurality of The bracket 14 is connected to provide other structures for assembling and use. Please see from the 9th and 10th figures at the same time, it is the curtain upper rail 30 for installing the curtain structure. The curtain structure can be generally If you see the curtains or roller blinds, the installation of the curtains on the rail can be completed without the use of electric and pneumatic tools, and at the same time, the wall is prevented from being damaged and the smoothness of the wall is ensured.

In addition, another use state of its structure, please see Fig. 11 again, the first and second channels 112, 122 formed by the support rod 10 in the outer tube 11 and the inner tube 12 that communicate with each other can also directly provide curtains Pieces and curtains are assembled, the curtain or the upper end of the curtain is provided with a plurality of sliding seats 40, and the sliding seats 40 are slidably installed on the first and second channels 112, 122, and accordingly the The support rod 10 is used as a curtain upper rail for the curtain sheet and the curtain to slide on the support rod 10 to open or close, so as to adjust the indoor light.

Another use state of its structure, please refer to Fig. 12 again, the support rod 10 can also be erected between the ground and the floor to form a use state of the support rod 10 like the sky and the ground. In actual use, First, the two inner tubes 12 of the support rod 10 are telescopically adjusted from both ends of the outer tube 11, and then the two positioning rods 13 are respectively passed through the positioning holes 111 of the outer tube 11 and the two positioning holes of the inner tube 12. 121 are connected in series, and then the two tightening nuts 132 and the two positioning rods 13 are locked and fixed by the bottom of the outer tube 11, thereby limiting the use length of the support rod 10. When the support rod 10 stands up, its upper end The abutting unit 20 of the upper part can be pressed against the upper floor first, and then the adjusting nut 221 of the abutting unit 20 at the lower end of the support rod 10 can be adjusted by screwing, so that the abutting column 22 can be extended against the ground, and at the same time The support rod 10 is pushed upward to make the abutting unit 20 at the upper end push up against the floor, so as to stand and fix the support rod 10 between the floor and the floor, so that a support rod 10 or A plurality of parallel support rods 10 are standing and fixed, and the connecting brackets 14 are installed in the first and second grooves 112 and 122 of the support rods 10 for the installation of the laminates 50 , which constitutes a one-layer frame structure.

With the structure of the above-mentioned specific embodiment, the following benefits can be obtained: the support rod 10 is formed by passing the outer tube 11 through at least two of the inner tubes 12, so that the support rod 10 can be seen between the two walls. The distance telescopically adjusts the length, which helps to improve the applicability of the support rod 10, and the abutting unit 20 is connected to the outer end of the inner tube 12 of the support rod 10, and the abutting unit 20 is used. After the abutting column 22 is screwed, it is firmly embedded in the two walls, and the assembly strength of the support rod 10 is improved, thereby completing the installation of the support rod 10, so as to provide a curtain structure or a laminate structure for assembly and use. The installation of the structure can be easily completed without electric and pneumatic tools, which greatly simplifies the installation process of the structure.

To sum up, the present invention has indeed achieved a breakthrough structural design, and has an improved content of the invention, and at the same time can achieve industrial applicability and progress, and the present invention has not been found in any publications, and it is also novel.
