Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy screen window frames, specifically to a push-pull aluminum alloy screen window frame with a buffer noise reduction mechanism. Background Technology

[0002] In traditional sliding aluminum alloy screen window designs, the opening and closing of the window sash is often accompanied by significant impact and noise. Especially under rapid pushing and pulling or inertia, the rigid collision between the window sash and the window frame not only produces a harsh sound, but long-term use can also easily lead to potential hazards such as profile deformation, loose hardware, and even glass breakage.

[0003] To alleviate this problem, some manufacturers have tried to add simple rubber buffer blocks or spring structures to the end of the window sash track. Although these basic buffering methods can absorb some impact energy, they still have obvious defects in actual use: the rubber blocks are prone to aging and hardening and lose their buffering effect, while the springs, due to the lack of damping control, cause the window sash to rebound or collide again, making it impossible to achieve smooth braking.

[0004] Therefore, it is necessary to invent a sliding aluminum alloy screen window frame with a buffer noise reduction mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a sliding aluminum alloy screen window frame with a buffer and noise reduction mechanism. The buffer is achieved through the cooperation of the window sash and the buffer mechanism, which solves the problems in the prior art where the rubber block is prone to aging and hardening and loses its buffering effect, and the spring causes the window sash to rebound or collide again due to the lack of damping control, thus failing to achieve smooth braking.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a push-pull aluminum alloy screen window frame with a buffer noise reduction mechanism, including a window sash. Buffer mechanisms are installed at the four corners inside the window sash. Each buffer mechanism includes four sets of fixed housings fixedly connected to the four corners of the window sash. A sliding part slides inside each fixed housing. A stabilizing block is fixedly connected to the inner wall of each fixed housing. Two sets of sliding rods are slidably connected to the inner wall of each stabilizing block. The sliding rods are fixedly connected to the sliding parts. A buffer rod is fixedly connected to the end of each sliding rod away from the sliding part. A limiting block is slidably connected to the outer wall of each buffer rod, and the limiting block is fixedly connected to the inside of the fixed housing. A buffer spring is sleeved on the outer wall of each buffer rod, and the buffer spring is fixedly connected to the limiting block. Two sets of soft buffer blocks are provided on the side of the buffer rod away from the stabilizing block. A hard buffer block is fixedly connected to the side of the soft buffer block away from the stabilizing block. The hard buffer block is fixedly connected to the inner wall of the fixed housing. A composite buffer is formed by the hard buffer block, the soft buffer block, and the buffer spring.

[0007] Preferably, a fixed cylinder is fixedly connected to the outer wall of the buffer rod, and a gap is left between the fixed cylinder and the hard buffer block, so as to further control the buffering force by cooperating with the hard buffer block and the soft buffer block.

[0008] Preferably, the inner wall of the window sash is provided with a sliding groove, a glass sealing strip is fixedly connected to the inner wall of the sliding groove, and a U-shaped sealing strip is fixedly connected to the inner wall of the sliding groove. The U-shaped sealing strip is located below the glass sealing strip, and the sliding groove and the U-shaped sealing strip initially reduce noise.

[0009] Preferably, a window frame is slidably connected inside the sliding groove, and an auxiliary sliding groove is provided at the bottom end of the window frame. A limiting protrusion slides inside the auxiliary sliding groove, and the window frame is used to install the screen window.

[0010] Preferably, a window screen is fixedly connected inside the window frame, the limiting protrusion is fixedly connected to the bottom wall of the sliding groove, and the two sides of the window frame are in contact with the glass sealing strip and the U-shaped sealing strip.

[0011] Preferably, the window sash has two sets of sound insulation layers and two sets of heat insulation layers installed inside it. The heat insulation layer is located inside the sound insulation layer, and the heat insulation layer and the sound insulation layer respectively achieve heat preservation and noise reduction.

[0012] Preferably, the inner wall of the window sash is fixedly connected with reinforcing ribs to increase the structural strength of the window sash.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] Through the cooperation of the window sash and the buffer mechanism, multi-level composite buffering is achieved through the built-in buffer mechanism at the four corners of the window sash. The buffer spring provides initial elastic energy absorption, while the soft and hard buffer blocks absorb the remaining impact force in sequence, effectively avoiding the aging and failure of traditional rubber blocks and the problem of spring rebound. At the same time, the sliding cooperation between the sliding rod and the limiting block creates a damping effect, ensuring smooth braking when the window sash is pushed or pulled to the end, completely eliminating secondary collision noise. The U-shaped sealing strip on the inside of the window sash is interference-fitted with the side of the window frame, forming a double sealing barrier with the glass sealing strip, significantly reducing wind noise and the risk of mosquito intrusion. The composite filling of the sound insulation layer and the heat insulation layer further blocks noise transmission and improves heat insulation performance. The precise guiding design of the auxiliary sliding groove and the limiting protrusion enhances the sliding stability of the window frame, while the reinforcing ribs greatly improve the overall deformation resistance of the window sash, making the product quiet, durable and highly airtight.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1-4The sliding aluminum alloy screen window frame with a buffer noise reduction mechanism shown includes a window sash 1. Buffer mechanisms 2 are installed at each of the four corners inside the window sash 1. Each buffer mechanism 2 includes four sets of fixed housings 201 fixedly connected to the interior of the four corners of the window sash 1. A sliding part 202 slides inside the fixed housing 201. A stabilizing block 203 is fixedly connected to the inner wall of the fixed housing 201. Two sets of sliding rods 204 are slidably connected to the inner wall of the stabilizing block 203. The sliding rods 204 are fixedly connected to the sliding part 202. A buffer rod 207 is fixedly connected to the end of the sliding rod 204 away from the sliding part 202. A limiting block 205 is slidably connected to the outer wall of the buffer rod 207, and the limiting block 205 is fixedly connected to the interior of the fixed housing 201. A buffer spring 206 is sleeved on the outer wall of the buffer rod 207, and the buffer spring 206 is fixedly connected to the limiting block 205. Two sets of soft buffer blocks 210 are provided on one side away from the stabilizing block 203. A hard buffer block 209 is fixedly connected to the side of the soft buffer block 210 away from the stabilizing block 203. The hard buffer block 209 is fixedly connected to the inner wall of the fixed housing 201. The hard buffer block 209, the soft buffer block 210 and the buffer spring 206 form a composite buffer. A fixed cylinder 208 is fixedly connected to the outer wall of the buffer rod 207. A gap is left between the fixed cylinder 208 and the hard buffer block 209. The cooperation of the hard buffer block 209 and the soft buffer block 210 further controls the buffering force. A sliding groove 5 is opened on the inner wall of the window sash 1. A glass sealing strip 6 is fixedly connected to the inner wall of the sliding groove 5. A U-shaped sealing strip 7 is fixedly connected to the inner wall of the sliding groove 5. The U-shaped sealing strip 7 is located below the glass sealing strip 6. The sliding groove 5 and the U-shaped sealing strip 7 initially reduce noise.

[0024] Refer to the instruction manual appendix Figure 1-4The window frame 3 is slidably connected inside the sliding groove 5. An auxiliary sliding groove 8 is provided at the bottom of the window frame 3, and a limiting protrusion 9 slides inside the auxiliary sliding groove 8. The window frame 3 is used to install the screen. A window screen 4 is fixedly connected inside the window frame 3. The limiting protrusion 9 is fixedly connected to the bottom wall of the sliding groove 5. The two sides of the window frame 3 are in contact with the glass sealing strip 6 and the U-shaped sealing strip 7. Two sets of sound insulation layers 10 and two sets of heat insulation layers 11 are installed inside the window sash 1. The heat insulation layer 11 is located inside the sound insulation layer 10. Heat insulation and noise reduction are achieved through the heat insulation layer 11 and the sound insulation layer 10, respectively. A reinforcing rib 12 is fixedly connected to the inner wall of the window sash 1, increasing the structural strength of the window sash 1. Through the cooperation of the window sash 1 and the buffer mechanism 2, multi-level composite buffering is achieved through the buffer mechanisms 2 built into the four corners of the window sash 1. Spring 206 provides initial elastic energy absorption, while soft buffer block 210 and hard buffer block 209 absorb the remaining impact force in sequence, effectively avoiding the aging and failure of traditional rubber blocks and the problem of spring rebound. At the same time, the sliding cooperation between sliding rod 204 and limiting block 205 forms a damping effect, ensuring smooth braking when window sash 1 is pushed or pulled to the end, completely eliminating secondary collision noise. The U-shaped sealing strip 7 on the inner side of window sash 1 is interference-fitted with the side of window frame 3, forming a double sealing barrier with glass sealing strip 6, significantly reducing wind noise and the risk of mosquito intrusion. The composite filling of sound insulation layer 10 and heat insulation layer 11 further blocks noise transmission and improves heat insulation performance. The precise guiding design of auxiliary sliding groove 8 and limiting protrusion 9 enhances the sliding stability of window frame 3, while reinforcing rib 12 greatly improves the overall deformation resistance of window sash 1, making the product quiet, durable and highly airtight.

[0025] The working principle of this practical application is as follows:

[0026] Refer to the instruction manual appendix Figure 1-4 When the window sash 1 is pushed or pulled along the sliding groove 5 to near the end, the sliding parts 202 at the four corners of the window sash 1 first contact the limiting structure of the window frame 3, pushing the sliding rod 204 to move into the fixed housing 201, causing the buffer rod 207 to compress the buffer spring 206. At this time, the spring absorbs most of the kinetic energy through elastic deformation. As the buffer rod 207 continues to move, the fixed cylinder 208 at its end gradually approaches the rigid buffer block 209, and the soft buffer block 210 in the middle is squeezed and deformed, further dissipating the remaining impact force. If the impact force is large, the fixed cylinder 208 eventually contacts the rigid buffer block 209, preventing the window sash 1 from moving excessively through rigid limiting. During this process, the precise sliding cooperation between the sliding rod 204 and the stabilizing block 203 generates frictional damping, while the restoring force of the buffer spring 206 is constrained by the limiting block 205, together ensuring that the window sash 1 remains stationary without rebound. Simultaneously, the U-shaped sealing strip 7 and the glass sealing strip 6 are always pressed tightly on both sides of the window frame 3 to form a dynamic seal; the sound insulation layer 10 inside the window sash 1 absorbs high-frequency noise, while the heat insulation layer 11 reduces heat conduction, ultimately achieving synergistic optimization of buffering, noise reduction, sealing and structural strength.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
