[0022] In the following description, embodiments of the floor-to-ceiling window railing of this utility model will be described with reference to the accompanying drawings. Example 1

[0023] Figure 1-4 This invention illustrates an embodiment of a floor-to-ceiling window railing, comprising a railing 1, with a buffer sleeve 14 fitted on the surface of the railing 1. Mounting holes 3 and 8 are aligned. The corners of the fixed base plate 5 are rounded. Four symmetrical connecting pipes 2 are fixedly connected to the bottom of the railing 1. Mounting holes 3 are provided on the left side of each connecting pipe 2. A mounting base pipe 4 is provided below each connecting pipe 2. A fixed base plate 5 is fixedly connected to the bottom of the mounting base pipe 4. A limit ring 6 is fixedly connected to the surface of the mounting base pipe 4. A fixed sleeve 7 is fixedly connected to the top of the mounting base pipe 4. A threaded collar 12 is fixedly connected to the surface of the fixed sleeve 7. A protective sleeve 13, which is funnel-shaped, is threaded onto the surface of the threaded collar 12. The sleeve 13 is designed so that after the fixing bolt 9 fixes the connecting pipe 2 and the fixing sleeve 7, the protective sleeve 13 is threadedly connected to the threaded collar 12. This allows the protective sleeve 13 to be fitted onto the surface of the fixing bolt 9, preventing the fixing bolt 9 bracket from being exposed to the air and reducing the rate of corrosion of the fixing bolt 9. The bottom of the protective sleeve 13 fits against the top of the limiting ring 6. The protective sleeve 13 is fitted onto the surface of the connecting pipe 2. The surface of the protective sleeve 13 is provided with anti-slip texture. The connecting pipe 2 is located in the inner cavity of the fixing sleeve 7. The left side of the fixing sleeve 7 has a second mounting hole 8. The inner cavity of the second mounting hole 8 is slidably connected to the fixing bolt 9. The fixing bolt 9 passes through the second mounting hole 8 and the first mounting hole 3 and is threadedly connected to a nut. Example 2

[0024] Figure 1-4This invention illustrates a floor-to-ceiling window railing according to an embodiment of the present invention. It includes a railing 1, with four symmetrical connecting pipes 2 fixedly connected to the bottom of the railing 1. Each connecting pipe 2 has a mounting hole 3 on its left side. A mounting base pipe 4 is located below each connecting pipe 2, and a fixing base plate 5 is fixedly connected to the bottom of the mounting base pipe 4. A limit ring 6 is fixedly connected to the surface of the mounting base pipe 4, and a fixing sleeve 7 is fixedly connected to the top of the mounting base pipe 4. Two symmetrical positioning grooves 10 are provided on the top of the fixing sleeve 7. Positioning blocks 11 are fixedly connected to both the front and back of each connecting pipe 2. The positioning grooves 10 and positioning blocks 11 are adapted to each other. When the connecting tube 2 enters the inner cavity of the fixed sleeve 7, the positioning groove 10 and the positioning block 11 can position the connecting tube 2 and the fixed sleeve 7, preventing the fixed sleeve 7 from deflecting on the surface of the connecting tube 2 and ensuring the neatness of the mounting hole 1 3 and the mounting hole 2 8. The positioning block 11 is rectangular, and the fixing bolt 9 is a hexagonal bolt. The fixing bolt 9 does not contact the inner wall of the protective sleeve 13. The connecting tube 2 is located in the inner cavity of the fixed sleeve 7. The fixed sleeve 7 has a mounting hole 2 8 on the left side. The mounting hole 2 8 is slidably connected to the inner cavity of the mounting hole 2 8. The fixing bolt 9 passes through the mounting hole 2 8 and the mounting hole 1 3 and is threaded with a nut.

[0025] Working principle: When using this utility model, the user places the fixing sleeve 7 on the surface of the connecting pipe 2, making the mounting hole 3 and the mounting hole 8 coincide, so that the fixing bolt 9 passes through the mounting hole 3 and the mounting hole 8 and is threadedly connected to the nut. Then, the fixing base plate 5 is placed next to the floor-to-ceiling window and fixed with the expansion bolts, thereby completing the installation of the railing 1. This avoids the need for users to break and cut it when dismantling and replacing it, improving the convenience of dismantling and replacing the floor-to-ceiling window railing. With the setting of the protective sleeve 13, after the fixing bolt 9 fixes the connecting pipe 2 and the fixing sleeve 7, the protective sleeve 13 is threadedly connected to the threaded collar 12, so that the protective sleeve 13 can be placed on the surface of the fixing bolt 9, preventing the fixing bolt 9 bracket from being exposed to the air and reducing the rate of corrosion of the fixing bolt 9.

[0026] In summary, this floor-to-ceiling window railing, by fitting the fixing sleeve 7 onto the surface of the connecting pipe 2, allows the fixing base plate 5 to reach the side of the floor-to-ceiling window. The fixing base plate 5 is then fixed with expansion bolts, and the fixing bolts 9 pass through mounting holes 1 and 2 and are threaded onto the nuts. This confines the connecting pipe 2 within the inner cavity of the fixing sleeve 7, achieving a secure connection for the floor-to-ceiling window railing. This avoids the need for users to break and cut the railing during disassembly and replacement, thus improving the convenience of disassembly and replacement of the floor-to-ceiling window railing.
