Abstract
Description
Technical Field
[0001] This utility model relates to the field of top and bottom axis technology, and in particular to a top and bottom axis with a buffer function. Background Technology
[0002] Top and bottom hinges (also known as top and bottom hinges or upper and lower hinges) are mainly used to connect and support the upper and lower ends of doors or windows, allowing them to open and close smoothly.
[0003] Existing hinges typically achieve opening and closing by installing a hinge at each end of the door or window, ensuring that the door or window can rotate smoothly and reliably. However, since the hinges need to be fixed with fasteners such as bolts, installation and disassembly are inconvenient, time-consuming, and labor-intensive, resulting in low efficiency in the installation and maintenance of doors.
[0004] Therefore, a top and bottom hinge with a buffer function has been developed that can quickly and easily complete assembly and disassembly, so as to improve installation and maintenance efficiency and save manpower. Utility Model Content
[0005] To overcome the shortcomings of existing hinges, which require bolts and other fasteners for fixing, making installation and disassembly inconvenient, time-consuming, and labor-intensive, resulting in low efficiency in door installation and maintenance, this utility model provides a hinge with a buffer function that can be quickly and easily assembled and disassembled, thereby improving installation and maintenance efficiency and saving manpower.
[0006] The technical solution is as follows: A top-bottom hinge with a buffer function includes rotating glass, side columns, bushings, rotating plates, a first column, a partition assembly, and a buffer waterproof assembly. The rotating glass has two sides, left and right, and bushings are snapped onto the opposite sides of the rotating glass. A rotating plate is rotatably connected to each bushing, and a side column is snapped onto each rotating plate. The first column is placed on the ground and is located between the rotating glass sections. A partition assembly capable of separating the space is provided on the first column, and a buffer waterproof assembly for buffering and waterproofing is provided between the rotating glass and the first column.
[0007] Preferably, handles are provided on both the front and back sides of the rotating glass.
[0008] Preferably, the partition assembly includes a second column and fixed glass. The second column is placed on the ground and is located behind the first column. The fixed glass is snapped between the first column and the second column.
[0009] As a preferred option, both the fixed glass and the rotating glass are coated with a frosted film.
[0010] As a preferred embodiment, the buffer waterproof component includes a protective sleeve, a magnetic waterproof strip, a matching strip, and an L-shaped column. The protective sleeve is snapped onto the side of the rotating glass that is close to each other, and the protective sleeve is connected to the magnetic waterproof strip. The L-shaped column is snapped onto the left and right sides of the first column, and the matching strip is connected to the side of the L-shaped column that is close to each other.
[0011] Preferably, the protective case is made of flexible material.
[0012] The beneficial effects of this utility model are as follows: By fixing the rotating glass to the bushing, then fixing the rotating plate to the side column, and then fixing the L-shaped column to the first column, when the magnetic waterproof strip and the matching strip are worn and aged, the protective sleeve and the L-shaped column can be removed and replaced. When the rotating glass needs to be replaced or repaired, the rotating plate can be removed from the side column. This achieves quick and convenient assembly and disassembly, which improves the efficiency of installation and maintenance, and saves manpower. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] A type of top and bottom axis with a buffer function, such as Figures 1-3 As shown, the device includes a rotating glass 1, side pillars 2, bushings 3, a rotating plate 4, a first column 9, a partition assembly, and a buffer waterproof assembly. The rotating glass 1 has two parts, left and right, and handles are provided on both the front and back sides for easy gripping. The bushings 3 are snapped onto the opposite sides of the rotating glass 1, and the rotating plate 4 is rotatably connected to each bushing 3. The side pillars 2 are snapped onto each rotating plate 4. The first column 9 is placed on the ground and is located between the rotating glass 1s. The first column 9 is equipped with a partition assembly, and a buffer waterproof assembly is provided between the rotating glass 1 and the first column 9.
[0019] like Figures 1-3As shown, the partition assembly includes a second column 10 and a fixed glass 11. The second column 10 is placed on the ground and is located behind the first column 9. The fixed glass 11 is snapped between the first column 9 and the second column 10. Both the fixed glass 11 and the rotating glass 1 are covered with frosted film to block external views.
[0020] like Figures 1-3 As shown, the buffer waterproof assembly includes a protective sleeve 5, a magnetic waterproof strip 6, a matching strip 7, and an L-shaped column 8. The protective sleeve 5 is snapped onto the side of the rotating glass 1 that is close to each other. The protective sleeve 5 is made of flexible material for easy protection. The magnetic waterproof strip 6 is connected to the protective sleeve 5. The L-shaped column 8 is snapped onto the left and right sides of the first column 9. The matching strip 7 is connected to the side of the L-shaped column 8 that is close to each other.
[0021] When using this utility model, firstly, the side column 2, the first column 9, and the second column 10 are installed between the ceiling and the floor. Then, the fixed glass 11 is fixed between the first column 9 and the second column 10. The rotating glass 1 is fixed on the bushing 3. Then, the rotating plate 4 is fixed on the side column 2. Subsequently, the L-shaped column 8 is fixed on the first column 9. When the user opens and closes the rotating glass 1, the bushing 3 rotates on the rotating plate 4. The protective sleeve 5 protects the sides of the rotating glass 1. When closed, the magnetic waterproof strip 6 and the matching strip 7 magnetically attract each other to buffer the rotating glass 1 and prevent moisture from leaking out. When the magnetic waterproof strip 6 and the matching strip 7 are worn and aged, the protective sleeve 5 and the L-shaped post 8 can be removed and replaced. When the rotating glass 1 needs to be replaced or repaired, the rotating plate 4 is removed from the side post 2, and then the rotating glass 1 is removed from the bushing 3. This allows for quick and convenient assembly and disassembly, improving installation and maintenance efficiency and saving manpower.
[0022] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
