Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a double-layer tempered glass fixing structure. Background Technology

[0002] Tempered glass is a type of safety glass. It is actually a prestressed glass. To improve the strength of the glass, chemical or physical methods are usually used to create compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the load-bearing capacity and enhancing the glass's resistance to wind pressure, temperature changes, and impact.

[0003] A search of patent number "CN219884457U" reveals a "Double-Layer Tempered Glass Fixing Structure," which relates to the field of tempered glass technology. This utility model includes a fixing block, with a positioning plate fixed to its upper surface; several grooves are formed on the upper surface of the fixing block, and a sliding plate is slidably connected inside the grooves; an adjusting plate is fixed to the top of the sliding plate, and a clamping plate is fixed to the bottom of the sliding plate; a tension spring is fixed between the adjusting plate and the positioning plate; a limiting groove is formed on one side of the fixing block, and a limiting block is fixed to one side of the clamping plate, with the limiting block slidably connected to the limiting groove; threaded tubes are fixed to both sides of the fixing block; threaded rods are threadedly connected inside the threaded tubes, and a baffle is fixed to one end of the threaded rods. Through the function of the fixing block, this utility model can fix multiple double-layer tempered glass panes while protecting their edges and corners, preventing damage to the edges and corners due to collisions between the double-layer tempered glass panes during subsequent transportation.

[0004] Relying solely on the elastic compression force of springs to fix double-glazed windows will cause the springs to gradually loosen due to metal fatigue when subjected to the weight of the glass, deformation caused by temperature changes, and environmental vibrations over a long period of time. This will lead to misalignment and displacement between the double-glazed windows. This dynamic displacement not only damages the seal but also causes uneven stress on the glass edges under wind pressure or mechanical vibration, ultimately leading to the risk of the glass loosening, making abnormal noises, or even falling off. Utility Model Content

[0005] The purpose of this invention is to provide a double-layer tempered glass fixing structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-layer tempered glass fixing structure, including a window frame and an inner frame, and further comprising:

[0007] A rubber layer is bonded to the inner frame. A cylindrical body is embedded at each of the four corners of the inner frame surface. An air extraction component is installed inside the window frame. A positioning block is installed through the inner surface of the window frame, and the positioning block is rotatably connected to the window frame through the window frame.

[0008] A screw rod is rotatably connected to both sides inside the window frame. A threaded sleeve is threadedly connected to the surface of the screw rod. A connecting rod is welded to one end of the threaded sleeve. A wedge block that cooperates with the positioning block is bolted to the other end of the connecting rod. A gear set is provided below the surface of the screw rod. Rotating columns are rotatably connected to both sides of the front of the window frame.

[0009] Preferably, the air extraction assembly includes a vertical cylinder, a connecting pipe, and a piston. There are two sets of vertical cylinders, which are respectively fixed on both sides inside the window frame. The connecting pipe is connected to the cylinder body, and the other end of the connecting pipe is connected to the vertical cylinder. The piston is slidably connected to the inner wall of the vertical cylinder. A movable column is also bolted to the surface of the piston. One end of the movable column extends to the outside of the vertical cylinder and is bolted to a connecting rod.

[0010] Preferably, the end of the rotating column is provided with a hexagonal groove.

[0011] Preferably, vertical strips are bolted to both sides of the inner wall of the window frame, and the threaded sleeve is slidably connected to the surface of the vertical cylinder.

[0012] Preferably, a horizontal column is bolted inside the window frame, a sliding sleeve is bolted to the bottom of the positioning block, and the sliding sleeve is slidably connected to the surface of the horizontal column. A limit block is also welded to the surface of the horizontal column.

[0013] Preferably, the gear set is composed of meshing bevel gears of different sizes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a rotating column and gear set to drive the screw to rotate, causing the threaded sleeve to lower the connecting rod and wedge block. This allows the positioning block to move and contact the glass surface, engaging with the inner frame for clamping and fixation. Simultaneously, the use of an air extraction component draws air from inside the cylinder to create negative pressure. Under the pressure difference between the inside and outside, the double-layered glass is further adsorbed and fixed. Combined with the use of the positioning block, the fixation is more secure, effectively preventing the glass from shifting or misaligning. Attached Figure Description

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] Please see Figures 1-9As shown, a double-layer tempered glass fixing structure includes a window frame 1 and an inner frame 2. The inner frame 2 is bolted to the inside of the window frame 1. A rubber layer 3 is bonded to the surface of the inner frame 2. Cylinders 4 are embedded in the four corners of the surface of the inner frame 2. An air extraction assembly 5 is installed inside the window frame 1. A positioning block 6 is installed through the inner surface of the window frame 1 and is rotatably connected to the through-hole of the window frame 1. A horizontal post 11 is also bolted to the inside of the window frame 1. A sliding sleeve 12 is bolted to the bottom of the positioning block 6 and is slidably connected to the surface of the horizontal post 11. When the positioning block 6 slides along the through-hole of the window frame 1, the positioning block 6 can drive the sliding sleeve 12 to slide along the surface of the horizontal post 11. A limit block 13 is also welded to the surface of the horizontal post 11 to control the range of motion of the sliding sleeve 12. To limit the movement and prevent the movable block from falling too deep into the interior of the window frame 1, screws 7 are rotatably connected to both sides of the interior of the window frame 1. Threaded sleeves 8 are threadedly connected to the surface of the screws 7. Vertical bars 14 are also bolted to both sides of the inner wall of the window frame 1. The threaded sleeves 8 are slidably connected to the surface of the vertical cylinder 51, allowing the threaded sleeves 8 to move up and down along the surface of the vertical bars 14, preventing the threaded sleeves 8 from rotating with the screws 7. A connecting rod 9 is welded to one end of the threaded sleeve 8, and a wedge block 10 that cooperates with the positioning block 6 is bolted to the other end of the connecting rod 9. A gear set 15 is provided below the surface of the screws 7. Rotating columns 16 are rotatably connected to both sides of the front of the window frame 1. The end of the rotating column 16 is provided with a hexagonal groove for inserting a hexagonal prism to rotate the rotating column 16.

[0028] First, place the double-layered tempered glass to be installed inside the window frame 1 and make contact with the rubber layer 3 and the end of the cylinder 4. Then, insert the hexagonal prism into the hexagonal slot at the end of the rotating column 16 to rotate it. The gear set 15 is composed of meshing bevel gears of different sizes. The gear ratio between the large bevel gear and the small bevel gear is 5:1. The rotating column 16 drives the screw 7 to rotate. The small gear drives the large gear to achieve the effect of saving effort. Then, the threaded sleeve 8 on the surface of the screw 7 drives the connecting rod 9 and the wedge block 10 to descend.

[0029] The air extraction assembly 5 includes a vertical cylinder 51, a connecting pipe 52, and a piston 53. Two sets of vertical cylinders 51 are fixed to the two sides inside the window frame 1. The connecting pipe 52 is connected to the cylinder body 4, and the other end of the connecting pipe 52 is connected to the vertical cylinder 51, linking the cylinder body 4 and the vertical cylinder 51. The piston 53 is slidably connected to the inner wall of the vertical cylinder 51. A movable column 54 is also bolted to the surface of the piston 53. One end of the movable column 54 extends to the outside of the vertical cylinder 51 and is bolted to the connecting rod 9. When the threaded sleeve 8 drives the connecting rod 9 to descend, it can drive the piston 53 to descend, increasing the volume above the interior of the vertical cylinder 51, decreasing the air pressure, and thus... Air from inside the cylinder 4 and the connecting pipe 52 enters the interior of the vertical cylinder 51, reducing the air pressure in the cylinder 4. Under the action of the pressure difference between the inside and outside, the glass is assisted in adsorption. At the same time, the wedge block 10 and the positioning block 6 come into contact with each other. When the two sets of inclined surfaces come into contact with each other, they are converted into a horizontal thrust that pushes the positioning block 6 toward the glass, so that the positioning block 6 comes into contact with the other side of the double-layer tempered glass and is fixed. The fixation is more secure. Then the same operation is performed on the other side. The self-locking friction of the screw 7, the combined downward gravity of the threaded sleeve 8, connecting rod 9, wedge block 10, and movable column 54 can all prevent the external air pressure from pushing the movable column 54 upward.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
