Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to an inward tilting and sliding door. Background Art

[0002] Initially, sliding doors were only used in bedrooms or dressing rooms. However, with the advancement of technology and the diversification of decoration methods, the functions and applications of sliding doors have continuously expanded, from traditional sheet materials to glass, fabric, rattan, and aluminum alloy profiles, and from sliding doors to folding doors and partition doors. In this context, the applications of sliding doors have become more diverse and rich. In addition to the most common partition doors, sliding doors are widely used in bookcases, wall cabinets, living rooms, showrooms, and sliding doors.

[0003] Existing sliding doors are all made of aluminum alloy, which has the advantages of high strength and not easy to deform. When the single door of the sliding door is pushed sideways to open, it facilitates air circulation. However, in the absence of people walking, the flow of air can easily allow mosquitoes from outside to enter the room. Of course, there are also sliding screen doors and windows installed on the door frame, but the screen will be exposed to the outside when not in use, and foreign objects can easily pierce the screen, affecting the overall appearance.

Two staggered sliding door bodies 3 are slidably installed between the vertical frames 1 and 2. A slit hole 4 is opened on the surface of the vertical frame 1. The inner wall of the slit hole 4 is rotatably connected to two symmetrically arranged auxiliary shafts 6 through a support 5. The support 5 is installed on the inner wall of the vertical frame 1, and its bottom is flush with the inner wall of the slit hole 4.

[0030] See also Figure 6-Figure 8The inner top wall and the inner bottom wall of the vertical frame 1 are fixedly installed with a shell seat 7, and a shell cover 8 is provided on the surface of the shell seat 7. A bearing seat 9 is embedded in the shell cover 8. A rotating shaft 10 is rotatably installed inside the bearing seat 9. Both ends of the outer side of the rotating shaft 10 are fitted with coil springs 11. One end of the inner side of the coil spring 11 is fixedly connected to the outer wall of the rotating shaft 10 through an extension plate 12, and the other end of the outer side of the coil spring 11 is fixedly connected to the inner wall of the shell seat 7 through the extension plate 12; when the gauze 13 is unfolded, the rotating shaft 10 will drive the coil spring 11 to tighten, and vice versa, the coil spring 11 is driven to restore its deformation, so that the rotating shaft 10 can reel in the gauze 13.

[0031] See also Figure 6-Figure 8 A gauze 13 is fixedly installed on the middle section of the outer side of the rotating shaft 10. The gauze 13 is inserted between the two auxiliary shafts 6. When the gauze 13 is pulled open, it will drive one of the auxiliary shafts 6 to rotate, so that the direct friction when the gauze 13 is unfolded is converted into rolling friction, thereby improving the service life of the gauze 13.

[0032] See also Figure 6-Figure 8 A magnetic strip 14 is fixedly installed at the other end of the gauze 13, and an L-shaped holder 15 corresponding to the two magnetic strips 14 is fixedly installed on the surface of the horizontal frame 2. The magnetic strips 14 are inserted into the inside of the L-shaped holder 15 and magnetically attracted to it, so as to fix the unfolded gauze 13; the two symmetrically arranged magnetic strips 14 on the left and right are magnetically fixed to each other, and the unfolded area of the two gauze nets 13 is larger than the inner area of the frame composed of the vertical frame 1 and the horizontal frame 2, so as to ensure that the entire door frame is blocked and mosquitoes are reduced from entering the room.

[0033] See also Figure 1-Figure 5 The sliding door body 3 can also be hinged between the vertical frame 1 and the horizontal frame 2 in an inward tilting opening mode. This not only ensures that the sliding door body 3 can be opened horizontally, but also has an inward tilting opening mode. Multiple opening modes are suitable for different air circulation. The inward tilting opening mode is a common technology in existing doors and windows. Manufacturers can add this technology according to the situation to meet customer needs.

[0034] Working principle: When the screen 13 is not unfolded, the coil spring 11 will twist the shaft 10 to wrap the screen 13 around its outside, and the magnetic strip 14 will be adsorbed on the gap hole 4 on the surface of the vertical frame 1. The magnetic strip 14 will block the two auxiliary shafts 6 to ensure that the entire door and window has a beautiful appearance when the screen 13 is not in use.

[0035] When the gauze 13 is unfolded, the gauze 13 is pulled and unfolded by the magnetic strip 14, and the rotation of the rotating shaft 10 will deform the coil spring 11, and then the magnetic strip 14 is inserted into the L-shaped holder 15 to prevent the gauze 13 from retracting. At the same time, the coil spring 11 will restore some strength to ensure that the gauze 13 is taut; on the contrary, the magnetic strip 14 is removed and loosened, the coil spring 11 is completely reset, and the rotating shaft 10 completely rewinds the gauze 13, hiding the gauze 13 in the vertical frame 1; in this process, not only the gauze 13 is unfolded to intercept mosquitoes, but also the gauze 13 is hidden after being rolled up, which is both beautiful and convenient.
