Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of buffer structures for sliding doors and windows, and more specifically, to buffer structures for aluminum alloy sliding doors and windows. Background Technology
[0002] In modern architectural decoration, aluminum alloy sliding doors and windows are widely used in various buildings due to their advantages such as good lighting and ventilation, as well as their aesthetic appeal, durability, and high space utilization. However, in terms of user experience, traditional aluminum alloy sliding doors and windows, lacking a buffer structure, cause violent collisions between the door / window sash and the frame during closing, generating significant noise. This noise not only affects the normal life and work of people inside but may also disturb nearby residents. Long-term violent collisions accelerate the wear and tear of door and window components. Under the impact of collisions, door and window glass frames, door / window frames, and connecting parts are prone to deformation, loosening, or even damage. Furthermore, some doors and windows use simple rubber strips or sponge strips as buffer components, which have limited buffering effect and are prone to aging and deformation, losing their buffering performance and affecting the usability. Therefore, a buffer structure for aluminum alloy sliding doors and windows is proposed. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an aluminum alloy sliding door and window buffer structure to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy sliding door and window buffer structure, including a fixed frame embedded in the bottom of the door and window glass frame and mounting plates fixed at both ends of the bottom of the door and window frame. The upper and lower sides of the middle ends of the fixed frame are provided with embedding grooves. The middle part of the embedding grooves is respectively embedded with a first magnetic plate and a second magnetic plate. The first magnetic plate and the second magnetic plate are limited and fixed by the embedding grooves. The inner cavity of the fixed frame is provided with buffer pads and buffer strips on both sides. The buffer pads and buffer strips can absorb the impact force generated by the collision of the door and window sashes, further reduce the collision noise, and reduce the hard friction and wear between the door and window sashes and the fixed frame.
[0005] One end of the fixed frame is inserted with a rod, and two sides of one end of the rod are symmetrically fixed with third magnetic plates. Through the cooperation of the third magnetic plate, the first magnetic plate, and the second magnetic plate, the magnetic attraction or repulsion can generate buffer resistance, slow down the closing speed of the door and window sash, and ensure the buffering effect of the rod being pulled and pushed. The other end of the rod is fixedly connected with an end plate, and a fourth magnetic plate is embedded on one side of the end plate. When the end plate is attached to the edge of the door and window frame, it is initially fixed by adsorption. An arc groove is opened at the bottom of the end plate, and a fixing block is fixedly connected to one side of the mounting plate. The fixing block is located directly below the end plate.
[0006] A top block is inserted into the top of the fixing block, and a limit strip is fixedly connected to the bottom of the top block. A spring is provided at the bottom of the limit strip. When the end plate moves from the top of the top block, it will press the top block, causing the top block to press against the spring until the top block corresponds to the arc groove. By pushing the top block with the spring, the top of the top block is inserted into the interior of the arc groove, fixing the position of the end plate. When the door and window glass frame drives the fixing frame to move, the end plate can drive the insertion rod to move out.
[0007] Preferably, the width of the fixing frame is the same as the width of the bottom cavity of the door and window glass frame. The fixing frame has first mounting holes at both ends and an opening on one side. The fixing frame can be easily installed and fixed through the first mounting holes, and the first magnetic plate and the second magnetic plate can be separated and removed through the opening on one side of the fixing frame.
[0008] Preferably, the first magnetic plate is disposed at both ends of the inner cavity of the fixed frame near the buffer pad, and the second magnetic plate is disposed at both ends of the inner cavity of the fixed frame near the buffer strip. The movement of the insertion rod can be buffered by the buffer pad and the buffer strip to avoid collision.
[0009] Preferably, the third magnetic plate has the same size as the first and second magnetic plates, a limiting groove is formed in the middle of the insertion rod, a limiting block is fixedly connected to one end of the middle of the fixing frame, the limiting block passes through the middle of the limiting groove, the limiting block and the limiting groove cooperate to limit and guide the movement of the insertion rod, and improve the stability of the movement of the insertion rod.
[0010] Preferably, the top of the top block is configured as an arc-shaped structure, the top block corresponds to the arc-shaped groove, the top of the top block extends to the middle of the arc-shaped groove, and the top block can be inserted into the interior of the arc-shaped groove to limit the position of the end plate.
[0011] Preferably, the limiting strip and the spring are both located in the middle of the fixing block, and the mounting plate has a second mounting hole in the middle. The mounting plate can be easily installed and fixed through the second mounting hole. The limiting strip and the spring limit the top block and make the top block generate an upward force.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model firstly uses a plug rod to drive the third magnetic plate to move between the first and second magnetic plates. The resistance generated between the third magnetic plate and the first and second magnetic plates can increase or decrease the resistance to the movement of the plug rod, thereby buffering the force of pulling and pushing the door and window. Furthermore, the buffer pad and buffer strip can prevent the plug rod from colliding with the fixed frame. The pressure of the end plate on the top block can further play a buffering role, reducing the impact and friction of the door and window sash and the door and window frame during the closing process, and reducing the wear of the door and window components.
[0014] 2. This utility model also uses a spring to push the top block, which allows the top block to be inserted into the arc-shaped groove to fix the position of the end plate. The fourth magnetic plate can be used to fit the end plate with the door and window frame to improve the closing effect of the door and window. The limiting block can slide inside the limiting groove to improve the stability of the insertion rod movement. The cooperation of the first mounting hole and the second mounting hole facilitates installation and fixing.
[0015] In summary, through the interaction of the above-mentioned multiple functions, the force of pulling and pushing the doors and windows can be buffered, reducing the collision impact and friction between the door and window sash and the door and window frame during the closing process, and reducing the wear and tear on the door and window components.

[0023] As attached Figure 1-3The aluminum alloy sliding door and window buffer structure shown includes a fixed frame 1 embedded in the bottom of the door and window glass frame and mounting plates 15 fixed at both ends of the bottom of the door and window frame. The upper and lower sides of the middle two ends of the fixed frame 1 are provided with embedding grooves 20. The middle part of the embedding grooves 20 is respectively embedded with a first magnetic plate 2 and a second magnetic plate 3. The first magnetic plate 2 and the second magnetic plate 3 are limited and fixed by the embedding grooves 20. The inner cavity of the fixed frame 1 is provided with buffer pads 4 and buffer strips 5 respectively. The buffer pads 4 and buffer strips 5 can absorb the impact force generated by the collision of the door and window sash, further reduce the collision noise, and reduce the hard friction and wear between the door and window sash and the fixed frame 1.
[0024] A rod 6 is inserted into one end of the fixed frame 1. A third magnetic plate 7 is symmetrically fixed to both sides of one end of the rod 6. Through the cooperation of the third magnetic plate 7, the first magnetic plate 2, and the second magnetic plate 3, a buffer resistance can be generated by magnetic attraction or repulsion to slow down the closing speed of the door and window sash and ensure the buffering effect of the rod 6 being pulled and pushed. An end plate 8 is fixedly connected to the other end of the rod 6. A fourth magnetic plate 9 is embedded on one side of the end plate 8. When the end plate 8 is attached to the edge of the door and window frame, it is initially fixed by adsorption. An arc groove 13 is opened at the bottom of the end plate 8. A fixing block 14 is fixedly connected to one side of the mounting plate 15. The fixing block 14 is located directly below the end plate 8.
[0025] A top block 17 is inserted into the top of the fixing block 14. A limit strip 18 is fixedly connected to the bottom of the top block 17. A spring 19 is provided at the bottom of the limit strip 18. When the end plate 8 moves from the top of the top block 17, it will press the top block 17, causing the top block 17 to press against the spring 19 until the top block 17 corresponds to the arc groove 13. By pushing the top block 17 with the spring 19, the top of the top block 17 is inserted into the interior of the arc groove 13, fixing the position of the end plate 8. When the door and window glass frame drives the fixing frame 1 to pull, the end plate 8 can drive the insertion rod 6 to move out.
[0026] As attached Figure 1-5As shown, the width of the fixed frame 1 is the same as the width of the bottom cavity of the window glass frame. First mounting holes 12 are provided at both ends of the fixed frame 1. An opening is provided on one side of the fixed frame 1. First magnetic plates 2 are located at both ends of the cavity of the fixed frame 1 near the buffer pad 4. Second magnetic plates 3 are located at both ends of the cavity of the fixed frame 1 near the buffer strip 5. Third magnetic plates 7 have the same dimensions as the first magnetic plates 2 and 3. A limiting groove 11 is provided in the middle of the insertion rod 6. A limiting block 10 is fixedly connected to one end of the middle of the fixed frame 1. The limiting block 10 passes through the middle of the limiting groove 11. The top of the top block 17 is designed with an arc shape, corresponding to the arc groove 13. The top of the top block 17 extends to the middle of the arc groove 13. The limiting strip 18 and the spring... Springs 19 are all located in the middle of the fixing block 14. The middle of the mounting plate 15 has a second mounting hole 16. The fixing frame 1 can be easily installed and fixed through the first mounting hole 12. The first magnetic plate 2 and the second magnetic plate 3 can be separated and removed through the opening on one side of the fixing frame 1. The buffer pad 4 and the buffer strip 5 can buffer the movement of the insertion rod 6 to avoid collision. The limiting block 10 cooperates with the limiting slide 11 to limit and guide the movement of the insertion rod 6, improving the stability of the movement of the insertion rod 6. The top block 17 can be inserted into the arc groove 13 to limit the position of the end plate 8. The mounting plate 15 can be easily installed and fixed through the second mounting hole 16. The top block 17 is limited by the limiting strip 18 and the spring 19, and the top block 17 generates an upward force.
[0027] The working principle of this utility model is as follows: When in use, the mounting plate 15 and the fixing block 14 are installed at both ends of the bottom of the door frame by bolts passing through the second mounting hole 16, and the fixing frame 1 is embedded in the bottom two sides of the door and window glass frame by bolts passing through the first mounting hole 12.
[0028] When the doors and windows are pushed to fit against the frame, the third magnetic plate 7 corresponds to the first magnetic plate 2, the fourth magnetic plate 9 fits against the door and window frame, the top block 17 is located in the middle of the arc groove 13, and the end plate 8 fits against the wall of the fixed frame 1.
[0029] Pulling the door and window causes the fixed frame 1 to move. Through the fourth magnetic plate 9 and the suction force, the resistance of the top block 17 sliding inside the arc groove 13, and the resistance generated by the misalignment of the third magnetic plate 7 and the first magnetic plate 2, the resistance of pulling the fixed frame 1 can be increased until the top block 17 separates from the arc groove 13 and the fourth magnetic plate 9 separates from the door and window frame. At this time, the third magnetic plate 7 corresponds to the second magnetic plate 3, and the fixed frame 1 separates from the door and window frame.
[0030] When the door and window move toward the door and window frame and are about to collide, the end plate 8 presses against the top block 17 to increase the sliding resistance. The third magnetic plate 7 and the second magnetic plate 3 are misaligned to generate resistance. The process of the third magnetic plate 7 moving to correspond with the first magnetic plate 2 will also generate resistance, which can buffer when the door and window are closed.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
