Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window technology, and in particular, to a low-noise, high-sealing aluminum alloy door and window. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made of extruded aluminum alloy profiles for the frame, mullions, and sashes, often simply called aluminum doors and windows. Aluminum alloy doors and windows have excellent corrosion resistance and weather resistance, adapting to various climates, are not prone to rust, and can ensure long-term normal use. Aluminum alloy doors and windows can be divided into sliding doors and windows and top-hung doors and windows according to their opening and closing methods. As the name suggests, sliding doors and windows have two sashes that slide horizontally on the same plane, while top-hung doors and windows are fixed at the top, with the sashes opening at an angle from the bottom. Considering both ease of opening and minimal space occupation, sliding doors and windows have gradually become the mainstream product in the decoration and building materials industry and are increasingly favored by consumers.

[0003] Sliding aluminum alloy doors and windows consist of a window frame and door panels installed within the frame. The doors and windows are opened or closed by horizontally pushing the door panels within a plane. However, in actual operation, excessive force can cause the door panels to open or close too quickly, resulting in a violent collision between the door panel and the window frame. This collision generates significant noise, disturbing nearby residents and posing a considerable risk of damage to the door panels. To mitigate these issues, some manufacturers install anti-collision strips on the inside of the door panels. These strips, made of rigid plastic, silicone, or rubber, can reduce noise to some extent when the door panel collides with them. A fixed anti-collision block is also installed at the bottom of the inner side of the window frame within the same plane. When the door is opened or closed, the bottom of the door panel's sidewall directly collides with the anti-collision block, reducing the impact area and thus lowering noise levels. However, regardless of whether the anti-collision strip is made of rigid plastic or silicone / rubber, its deformation is relatively limited when the door panel collides with it, making it difficult to guarantee a proper seal between the window frame and the door panel, resulting in poor sound insulation. Therefore, it is necessary to improve the structure of aluminum alloy doors and windows to overcome the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, an aluminum alloy door and window with good sealing performance and low noise is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a low-noise, high-sealing aluminum alloy door and window, including a window frame, a fixed door leaf and a movable door leaf. The fixed door leaf is fixedly installed in the window frame. The window frame has sliding grooves on the upper and lower sides and adapter grooves on the left and right sides. The movable door leaf is located in front of the fixed door leaf and is slidably connected to the sliding grooves. An anti-collision strip made of elastic material is fixedly installed in the adapter groove. The anti-collision strip has a sealed cavity inside, which is filled with filling gas. A locking member is movably inserted on the front surface of the window frame away from the fixed door leaf. A locking hole is opened on one side of the movable door leaf corresponding to the locking member. The end of the locking member can be inserted into the locking hole.

[0006] Furthermore, the side of the movable door leaf near the locking member is provided with an inclined surface, which can abut against the end of the locking member, and an elastic element is provided between the locking member and the window frame in a telescopic manner along the direction of movement of the locking member.

[0007] Furthermore, a fixing sleeve is fixedly installed on the window frame. One end of the fixing sleeve is open, and the locking member can be movably inserted through the fixing sleeve. A retaining edge is protruding from the outer wall of the locking member inside the fixing sleeve. One end of the elastic member abuts against the inner wall of the fixing sleeve, and the other end of the elastic member abuts against the retaining edge.

[0008] Furthermore, the elastic element is a spring sleeved on the outside of the locking element.

[0009] Furthermore, a limiting edge is provided on the outer wall of the locking member outside the fixed sleeve, and the limiting edge can abut against the end of the fixed sleeve.

[0010] Furthermore, one end of the locking member extends into the adapter groove under the elastic force of the elastic member, and a pull ring is fixedly installed on the end of the locking member located outside the adapter groove.

[0011] Furthermore, the anti-collision strip is made of rubber material.

[0012] Furthermore, the filling gas is nitrogen.

[0013] The beneficial effects of this utility model are as follows: The low-noise, high-sealing aluminum alloy door and window of this utility model has an anti-collision strip fixedly connected in the adapter groove. The anti-collision strip is made of elastic material and has a sealed cavity inside. The sealed cavity is filled with gas. When the frame of the movable door leaf collides with the anti-collision strip, the anti-collision strip can adapt to the shape of the edge of the movable door leaf, so that the anti-collision strip can fit more closely to the side wall of the movable door leaf, thereby forming a good seal and playing a buffering role. While reducing noise, it also prevents the movable door leaf from being easily damaged by collision. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Please see Figures 1-7 This utility model provides a low-noise, high-sealing aluminum alloy door and window, including a window frame 1, a fixed door leaf 2, and a movable door leaf 3. The window frame 1 has a rectangular frame structure. The fixed door leaf 2 is fixedly installed inside one side of the window frame 1, and the movable door leaf 3 is slidably installed inside the window frame 1. When the movable door leaf 3 is slidably installed inside the other side of the window frame 1, the fixed door leaf 2 and the movable door leaf 3 completely fill the space inside the window frame 1. Specifically, the movable door leaf 3 is located in front of the fixed door leaf 2. When the movable door leaf 3 is slidably installed to completely overlap with the fixed door leaf 2, the aluminum alloy door and window is in a half-open state; when the movable door leaf 3 is slidably installed to completely offset from the fixed door leaf 2, the aluminum alloy door and window is in a closed state.

[0025] Please see Figure 5 , Figure 7 The window frame 1 has sliding grooves 101 on the upper and lower sides and fitting grooves 102 on the left and right sides. In this embodiment, the window frame 1 is formed by four aluminum profiles with U-shaped cross-sections fixedly connected at the ends. Specifically, the window frame 1 includes two horizontal frames 11 on the upper and lower sides and two vertical frames 12 on the left and right sides. The opposing surfaces of the two horizontal frames 11 are recessed to form sliding grooves 101, and the opposing surfaces of the two vertical frames 12 are recessed to form fitting grooves 102. The movable door 3 is slidably installed in the sliding grooves 101 in the horizontal direction. When the movable door 3 is moved to either the left or right side of the window frame 1, the side of the movable door 3 is inserted into the fitting groove 102 on the corresponding side.

[0026] In this embodiment, a crash strip 4 is fixedly connected to the bottom wall of the adapter groove 102 by adhesive. The crash strip 4 is made of elastic material and has a long strip structure. A sealed cavity 41 is formed inside the crash strip 4 along its length. The sealed cavity 41 is filled with filling gas and expands under the action of the filling gas. In this embodiment, the crash strip 4 is made of rubber material and the filling gas 4 is nitrogen. When the movable door 3 moves to the left or right edge of either side of the window frame 1, the movable door 3 may collide with the crash strip 4. The crash strip 4 will deform under the impact of the movable door 3, so that the sealed cavity 41 is gradually squeezed and deformed. During this process, the crash strip 4 can play a buffering role, effectively avoiding excessive collision between the movable door 3 and the window frame 1, reducing the noise generated during the collision, and reducing the impact on the movable door 3, preventing the movable door 3 from being easily damaged.

[0027] In this embodiment, a locking member 5 is movably inserted into the front surface of the window frame 1 on the side away from the fixed door leaf 2. A locking hole 31 is provided on one side of the movable door leaf 3 corresponding to the locking member 5, and the end of the locking member 5 can be inserted into the locking hole 31. When the movable door leaf 3 moves away from the fixed door and window 2 into the adapter groove 102 of the window frame 1, the movable door leaf 3 compresses the anti-collision strip 4 under the action of external force, and finally makes the locking hole 31 and the locking member 5 aligned. At this time, the locking member 5 is inserted inward, so that the end of the locking member 5 can be inserted into the locking hole 31, thereby locking the movable door leaf 3 onto the window frame 1, thus realizing the fixing effect between the two. Since the interior of the anti-collision strip 4 is a sealed cavity and the anti-collision strip 4 is made of deformable material, the anti-collision strip 4 can adapt to the shape of the edge of the movable door leaf 3, which plays a buffering role and also makes the anti-collision strip 4 fit more closely to the side wall of the movable door leaf 3, thereby forming a good seal and greatly reducing the noise generated by the collision. In addition, the elastic force generated when the anti-collision strip 4 is deformed under pressure will act on the movable door leaf 3, thereby pushing the movable door leaf 3. This force can prevent the locking member 5 from easily moving out of the locking hole 31, thus improving the locking stability of the locking member 5 on the window frame 2 and the movable door leaf 3.

[0028] In a preferred embodiment, the side of the movable door leaf 3 near the locking member 5 is provided with a slope 32. An elastic member 6 is provided between the locking member 5 and the window frame 1 along the moving direction of the locking member 5. Under the elastic force of the elastic member 6, the locking member 5 has a tendency to move inward. Therefore, when the elastic member 6 is in its natural state, one end of the locking member 5 extends into the adapter groove 102. When the movable door leaf 3 moves towards the side where the locking member 5 is located, the slope 32 on the movable door leaf 3 will abut against the end of the locking member 5. As it continues to move, it forces the end of the locking member 5 to slide along the slope 32. At this time, the locking member 5 gradually moves outward and finally abuts against the front surface of the movable door leaf 3. When the movable door leaf 3 moves to the locking hole 31 and aligns with the locking member 5, the locking member 5 will automatically move inward under the elastic force of the elastic member 6 and then insert into the locking hole 31 to lock the movable door leaf 3 onto the window frame 1. One end of the locking element 5 is spherical to facilitate contact with the inclined surface 32 and to prevent excessive wear on the inclined surface 32.

[0029] Furthermore, a fixing sleeve 7 is fixedly installed on the window frame 1. The fixing sleeve 7 is a cylindrical structure with one open end. The locking member 5 is a cylindrical structure and can movably pass through the fixing sleeve 7. A retaining edge 51 is protruding from the outer wall of the locking member 5 inside the fixing sleeve 7. An elastic member 6 is sleeved on the outside of the locking member 5. One end of the elastic member 6 abuts against the inner wall of the fixing sleeve 7, and the other end of the elastic member 6 abuts against the retaining edge 51. In this way, the locking member 5 has an inward tendency to move, ensuring that one end of the locking member 5 can extend into the fitting groove 102 when the elastic member 6 is in its natural state. In this embodiment, the elastic member 6 is a spring.

[0030] In a preferred embodiment, a limiting edge 52 protrudes from the outer wall of the locking member 5 outside the fixed sleeve 7, and the limiting edge 52 abuts against the end of the fixed sleeve 7. When the movable door leaf 3 is not inserted into the adapter groove 102, the limiting edge 52 abuts against the end of the fixed sleeve 7 under the elastic force of the elastic member 6. Therefore, the length of the locking member 5 extending into the adapter groove 102 can be limited, thereby ensuring that the inclined surface 32 can contact the end of the locking member 5 and ultimately push the locking member 5 to move when the movable door leaf 3 moves.

[0031] In this embodiment, a pull ring 53 is fixedly installed on one end of the locking member 5 located outside the adapter groove 102. The pull ring 53 can be gripped by the user to pull the locking member 5 outward so that the locking member 5 is disengaged from the locking groove 31, and then the movable door leaf 3 can be further moved.

[0032] In addition, in this embodiment, rubber strips 33 are fixedly installed on the left, upper and lower side frames of the rear surface of the movable door leaf 3. When the movable door leaf 3 is completely closed, the rubber strip 33 on the left side frame is in contact with the right side frame of the fixed door leaf 2, while the rubber strips 33 on the upper and lower side frames are in contact with the side wall of the groove 101, thereby ensuring the sealing of the four sides of the movable door leaf 3 and improving the sound insulation effect.

[0033] Furthermore, both the fixed door leaf 2 and the movable door leaf 3 are composed of a quadrilateral frame and transparent glass fixed within the frame.

[0034] This utility model discloses a low-noise, high-sealing aluminum alloy door and window. An anti-collision strip 4 is fixedly connected in the adapter groove 102. The anti-collision strip 4 is made of elastic material and has a sealed cavity 41 inside. The sealing cavity 41 is filled with the filling gas. When the frame of the movable door leaf 3 collides with the anti-collision strip 4, the anti-collision strip 4 can adapt to the shape of the edge of the movable door leaf 3, so that the anti-collision strip 4 can fit more closely to the side wall of the movable door leaf 3, thereby forming a good seal and playing a buffering role. While reducing noise, it also prevents the movable door leaf 3 from being easily damaged by collision.

[0035] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
