Description
Technical Field
[0001] This utility model belongs to the technical field of door and window accessories, and in particular relates to thermally broken aluminum door and window sliding supports. Background Technology
[0002] Common aluminum alloy door and window frames are made of aluminum alloy. However, aluminum, as a metal with good thermal conductivity, does not effectively insulate against indoor and outdoor temperatures. This results in rapid heat loss from the interior in winter and indoor temperatures approaching outdoor temperatures in summer, significantly reducing insulation performance. Thermally broken aluminum doors and windows offer superior performance compared to ordinary aluminum alloy profiles. Thermally broken aluminum involves breaking the aluminum alloy in the middle and connecting the broken sections with a rigid plastic. Plastic conducts heat much slower than metal, making it difficult for heat to pass through the entire door and window, thus improving insulation performance. A sliding support is a component that connects the window sash and frame profile. With the development of the construction industry and the improvement of people's living standards, people's demands for the aesthetics and safety of doors and windows are increasing. To ensure that the window sash has a high degree of structural concealment and aesthetics during use, a linkage structure sliding support has emerged.
[0003] In window and door sliding supports, the slider moves within a fixed track, during which wear occurs between the two. To reduce frictional loss, a thermally broken aluminum window and door sliding support is needed. By applying solid lubricant to the surface of the slider and using a spring, the solid lubricant can be coated onto the inner wall of the fixed track, thus lubricating the inner wall and reducing frictional loss during actual use. Utility Model Content
[0004] The purpose of this utility model is to provide a sliding support for aluminum alloy doors and windows. By setting a solid lubricant on the surface of the slider and by setting a spring, the solid lubricant can be applied with elastic force, so that the solid lubricant can be applied to the inner wall of the fixed slide rail, thereby lubricating the inner wall of the fixed slide rail, and reducing the friction loss of the door and window sliding support in actual use, so as to solve the technical problems mentioned in the background art.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A thermally broken aluminum window / door sliding support includes a fixed slide rail; a slider is slidably connected to the inner wall of the fixed slide rail; a connecting rod one is rotatably connected to the surface of the fixed slide rail via a rotating shaft; a connecting rod two and a connecting rod three are rotatably connected to the surface of the slider via a rotating shaft; a window sash and a window frame are provided on the outer side of the fixed slide rail; a top block is fixedly connected to the top of the slider; a rectangular block is provided on the top of the top block; a strip is integrally formed at the bottom of the rectangular block; a bolt rod is provided through the surface of the strip; a rectangular cavity and a slot are opened inside the rectangular block; a sliding plate is provided inside the rectangular cavity; an L-shaped lever and a solid lubricant block are fixedly connected to the surface of the sliding plate; and a spring is fixedly connected between the sliding plate and the inner wall of the rectangular cavity.
[0006] Preferably, the second connecting rod is rotatably connected to the first connecting rod via a pivot, and both the first connecting rod and the third connecting rod are rotatably connected to the window sash via pivots. The fixed slide rail is fixedly installed on the surface of the window frame by bolts.
[0007] Preferably, the end of the bolt rod passes through the strip and extends into the interior of the top block, and the surfaces of the strip and the top block are respectively provided with through holes and threaded holes adapted to the bolt rod.
[0008] Preferably, a sleeve block is fixedly connected to the surface of the skateboard, and the inner wall of the sleeve block is in contact with a solid lubricant block.
[0009] Preferably, the surface of the skateboard is integrally formed with a limiting block, and the inner wall of the rectangular cavity is provided with a limiting groove that matches the limiting block.
[0010] The beneficial effects of this utility model are:
[0011] This utility model uses the combination of strips and bolts to fix a rectangular block to the top of the top block. The spring force applies force to the sliding plate, which in turn causes the solid lubricant block to adhere tightly to the inner wall of the fixed slide rail. This achieves the purpose of applying solid lubricant to the surface of the slider and applying elastic force to the solid lubricant through the spring, so that the solid lubricant can be applied to the inner wall of the fixed slide rail, thereby lubricating the inner wall of the fixed slide rail and reducing friction loss of door and window sliding supports in actual use.
[0012] 2. By setting the sleeve block, this utility model limits the connection of the solid lubricant block on the skateboard surface, further improving the stability of the solid lubricant block fixed on the skateboard surface, thereby improving the positional stability of the solid lubricant block.
[0013] 3. This utility model uses the combination of limiting blocks and limiting grooves to limit the movement of the skateboard, preventing the skateboard from shaking during movement and thus improving the stability of the skateboard during movement. Attached Figure Description

A rectangular block 9 is provided on the top of the top block 8. A strip 10 is integrally formed on the bottom of the rectangular block 9. A bolt rod 11 is provided through the surface of the strip 10. The end of the bolt rod 11 passes through the strip 10 and extends into the interior of the top block 8. Through holes and threaded holes adapted to the bolt rod 11 are respectively opened on the surface of the strip 10 and the top block 8. A rectangular cavity 12 and a groove 13 are opened inside the rectangular block 9. A sliding plate 14 is provided in the inner cavity of the rectangular cavity 12. An L-shaped locating plate 15 and a solid lubricant block 16 are fixedly connected to the surface of the sliding plate 14. A spring 18 is fixedly connected between the sliding plate 14 and the inner wall of the rectangular cavity 12. Example 2
[0024] Figure 1-5 This invention illustrates an embodiment of a thermally broken aluminum window / door sliding support, comprising a fixed slide rail 1; a slider 2 slidably connected to the inner wall of the fixed slide rail 1; a connecting rod 3 rotatably connected to the surface of the fixed slide rail 1 via a pivot; a connecting rod 4 and a connecting rod 5 rotatably connected to the surface of the slider 2 via a pivot; a window sash 6 and a window frame 7 are provided on the outer side of the fixed slide rail 1; a top block 8 is fixedly connected to the top of the slider 2; a rectangular block 9 is provided on the top of the top block 8; a strip 10 is integrally formed at the bottom of the rectangular block 9; a bolt rod 11 is provided through the surface of the strip 10; a rectangular cavity 12 and a groove 13 are provided inside the rectangular block 9; a sliding plate 14 is provided inside the rectangular cavity 12; an L-shaped trolley 15 and a solid lubricant block 16 are fixedly connected to the surface of the sliding plate 14; and the surface of the sliding plate 14 is fixedly connected to... A sleeve 17 is attached, and the inner wall of the sleeve 17 fits against the solid lubricant block 16. The sleeve 17 limits the connection of the solid lubricant block 16 on the surface of the slide plate 14, further improving the stability of the solid lubricant block 16 fixed on the surface of the slide plate 14, thereby improving the positional stability of the solid lubricant block 16. A spring 18 is fixedly connected between the slide plate 14 and the inner wall of the rectangular cavity 12. A limiting block 19 is integrally formed on the surface of the slide plate 14. A limiting groove 20 adapted to the limiting block 19 is opened on the inner wall of the rectangular cavity 12. Through the cooperation of the limiting block 19 and the limiting groove 20, the movement of the slide plate 14 is limited, avoiding the slide plate 14 from shaking during movement, thereby improving the stability of the slide plate 14 during movement.
[0025] Working principle: When using this utility model, the user moves the L-shaped lever 15 relative to the inner cavity of the lever groove 13 by moving it. This causes the L-shaped lever 15 to compress the spring 18 through the slide plate 14 and drive the solid lubricant block 16 back into the rectangular block 9. Then, the rectangular block 9 is placed on the top of the top block 8. Next, the rectangular block 9 is fixed to the top of the top block 8 by the cooperation of the strip plate 10 and the bolt rod 11. Then, the L-shaped lever 15 is released. At this time, the spring force of the spring 18 applies force to the slide plate 14. Then, the slide plate 14 drives the solid lubricant block 16 to stick tightly to the inner wall of the fixed slide rail 1. When the slider 2 slides on the inner wall of the fixed slide rail 1, the solid lubricant block 16 can be applied to the inner wall of the latter. This realizes that by setting solid lubricant on the surface of the slider and setting the spring, the solid lubricant can be applied to the solid lubricant, so that the solid lubricant can be applied to the inner wall of the fixed slide rail, thereby lubricating the inner wall of the fixed slide rail and reducing the friction loss of the door and window sliding support in actual use.
[0026] In summary, this thermally broken aluminum window and door sliding support, through the combined use of strip plate 10 and bolt rod 11, fixes rectangular block 9 to the top of top block 8, and applies force to slide plate 14 through the elastic force of spring 18. Subsequently, slide plate 14 drives solid lubricant block 16 to adhere tightly to the inner wall of fixed slide rail 1. This achieves the purpose of applying solid lubricant to the surface of the slider and applying elastic force to the solid lubricant through the spring, so that the solid lubricant can be applied to the inner wall of the fixed slide rail, thereby lubricating the inner wall of the fixed slide rail and reducing friction wear of the window and door sliding support in actual use.
