The embodiments of the present disclosure may be executed independently of each other, or may be executed together in a mutually dependent relationship.

[0025] Refer to Figures 1 to 4, the present utility model discloses a trackless single-opening shower door, which includes a fixed door 1 and a movable door 2. The periphery of the fixed door 1 is provided with a fixed frame. The fixed frame is preferably made of aluminum profiles, and includes side frame bars 3 located on both sides of the fixed door 1 and end frame bars 4 located at the upper and lower ends. An end groove is provided on the end frame bar 4, and the end edge of the fixed door 1 is embedded in the end groove. A side groove is provided on the side frame bar 3, and the end of the end frame bar 4 and the side of the fixed door 1 are both embedded in the side groove. The side frame bar 3 and the end frame bar 4 are both square. Glue is applied in both the end groove and the side groove to fix the fixed door 1. The side frame bar 3 against the wall is fixed to the wall by screws. The side frame bar 3 against the wall has an extension plate, which is convenient for installing an anti-collision rubber strip. The periphery of the movable door 2 is also provided with a frame, and its structure is similar to that of the fixed frame of the fixed door 1, so it will not be described in detail. The movable door 2 is slidably matched with the lower guide rail through rollers 5. A connecting member 6 is provided on the fixed door 1, and an upper frame bar 7 is provided on the movable door 2. The upper frame bar 7 is a part of the frame of the movable door 2. A guide groove 8 is provided on the upper surface of the upper frame bar 7, and an installation groove 9 is provided on the lower surface of the upper frame bar 7. For the convenience of processing, the guide groove 8 and the installation groove 9 are square grooves and both ends are through. The upper end of the fixed door 1 is embedded in the installation groove 9 and fixed by applying glue. A guide member 10 is provided on the connecting member 6 to prevent the movable door 2 from swaying in cooperation with the guide groove 8. The guide member 10 is located in the guide groove 8 and can slide in contact with the inner wall of the guide groove 8 when the movable door 2 moves, so as to avoid the upper end of the movable door 2 from swaying.

[0026] As shown in the figure, the guide member 10 is preferably a guide wheel. The guide wheel is located in the guide groove 8, and the guide wheel is rotatably connected to the connecting member 6 through a guide shaft 11. In this way, the guide wheel is in rolling contact with the inner wall of the guide groove 8, greatly reducing the friction and improving the service life of the guide member 10. Of course, the guide member 10 can also be non-rotating, and a cylindrical or frustum-shaped structure made of nylon can be used to slide-friction with the inner wall of the guide groove 8.

[0027] As shown in the figure, the connecting member 6 includes a connecting plate 12 and a cantilever plate 13. The guide shaft 11 is fixed to the cantilever plate 13. The connecting plate 12 and the cantilever plate 13 are square plates formed integrally by bending. The connecting plate 12 and the cantilever plate 13 are perpendicular to each other. The connecting plate 12 is fixed to the side frame bar 3 by screws. In this way, when the connecting plate 12 is fixed, the guide shaft 11 is just above the guide groove 8.

[0028] As shown in the figure, the guiding shaft 11 includes a boss 14 and a shaft rod 15. The diameter of the boss 14 is larger than that of the shaft rod 15. Therefore, a step surface is formed at the intersection of the boss 14 and the shaft rod 15. A connecting screw hole is provided at the end of the shaft rod 15. The shaft rod 15 passes through the inner hole of the guiding wheel and is connected with a locking screw (not shown in the figure) to fix the guiding wheel to the guiding shaft 11. In this application, the guiding wheel is preferably a bearing. The inner ring of the bearing is fixed by being pressed by the step surface and the locking screw. Of course, we can also use a rubber wheel with an inner hole. In the structure, the length of the shaft rod 15 is longer than the inner hole of the rubber wheel. After the locking screw is assembled with the shaft rod 15 through the connecting screw hole, it will not be pressed, so that the rubber wheel is not locked and can rotate, but it cannot come off the shaft rod 15.

[0029] The above has introduced in detail an upper-rail-free single-opening shower door provided by an embodiment of the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
