Description

Technical Field

[0001] This utility model relates to the field of sealing strip technology, and in particular to a weather-resistant sealing strip structure for aluminum-plastic doors and windows. Background Technology

[0002] PVC windows and doors are made primarily from polyvinyl chloride (PVC) resin, along with a certain proportion of stabilizers, colorants, fillers, and UV absorbers. The mixture is extruded into profiles, which are then cut, welded, or screwed together to form window and door frames. Sealing strips, weatherstripping, and hardware are added. To enhance the rigidity of the profiles, steel reinforcement (stiffening ribs) is added to the cavities of profiles exceeding a certain length. PVC windows and doors are widely used in daily life; however, most PVC windows currently available have poor sealing, with gaps between two sliding PVC windows, making it cold to sit near them in winter.

[0003] Chinese utility model patent CN208441743U discloses a PVC window and door sealing strip structure, including a PVC window body. A sealing groove is embedded on one side of the front of the PVC window body, and an insertion port that communicates with the sealing groove is provided on the side of the PVC window body. In this utility model, when installing the fixing plate, the fixing plate is inserted into the insertion port on the side of the PVC window body. The smooth curved surface of the locking block is pressed and retracts into the groove. After the fixing plate enters the groove, the locking block pops out and locks into both ends of the sealing groove. When the fixing plate is inserted into the sealing groove, the sealing plate slides into the surface of the PVC window body. When the locking block is locked into the sealing groove, the sealing plate is fixed. When removing the fixing plate, the actuating block is pulled to retract the locking block into the groove and pull the fixing plate outward. When the PVC window is closed, the two PVC windows fit tightly together, and the two sealing strips between them are tightly squeezed together, providing good sealing and preventing cold air from entering the room.

[0004] Regarding the aforementioned technology, the inventors believe it suffers from the following drawbacks: The device seals the window frame using two sealing strips mounted on two sealing plates. During use, the operator must connect the fixing plate to the insertion port to ensure stability under the action of the locking block. However, in actual use, due to tolerance issues in the manufacturing of the locking block, a gap may remain between the locking block and the sealing groove when the fixing plate is connected to the insertion port. This gap can easily cause slight shaking of the fixing plate under external force, resulting in a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a weather-resistant sealing strip structure for aluminum-plastic doors and windows.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a weather-resistant sealing strip structure for aluminum-plastic doors and windows, including a PVC window body, an insertion port provided on the side wall of the PVC window body, a fixing plate slidably disposed in the insertion port, a sealing plate provided on the side wall of the fixing plate, a sealing strip connected to the sealing plate, sliding grooves provided on the upper and bottom surfaces of the fixing plate, and a limiting component for limiting the fixing plate.

[0007] By adopting the above technical solution, when workers need to install the sealing strip, they simply connect the fixing plate to the insertion port and push the fixing plate, which automatically stabilizes the fixing plate under the action of the sliding rod. Furthermore, workers only need to activate the drive device to allow the sliding rod to continue moving upwards, thereby improving the tightness of the connection between the fixing plate and the insertion port and reducing the probability of slight shaking when the fixing plate is subjected to external force. Furthermore, workers only need to close the two PVC window bodies to ensure that the two sealing strips on the two PVC window bodies are pressed together, thus improving the sealing performance of the PVC window bodies.

[0008] Furthermore, the limiting component includes a sliding rod slidably disposed in the sliding groove, a compression spring fixed at one end to the bottom surface of the sliding rod, and a driving device disposed on the fixing plate for driving the sliding rod. The other end of the compression spring is fixed to the inner bottom wall of the sliding groove, and fixing holes matching the sliding rod are provided on the inner top wall and inner bottom wall of the insertion port.

[0009] Furthermore, a first threaded groove is formed on the inner wall of the sliding groove, and a first inclined surface is formed on the edge of the sliding rod where the side wall away from the compression spring intersects with the side wall away from the first threaded groove.

[0010] By adopting the above technical solution, when the operator connects the fixing plate to the insertion port, the first inclined surface abuts against the edge of the insertion port, thereby causing the sliding rod to move completely into the sliding groove under the action of the fixing plate. Subsequently, when the sliding groove is aligned with the fixing hole, the sliding rod connects with the fixing hole under the action of the compression spring, thus initially stabilizing the sliding rod. Furthermore, the operator only needs to activate the drive device to allow the sliding rod to continue moving upward under the action of the drive device, thereby improving the tightness of the connection between the sliding rod and the fixing hole, and further improving the tightness of the connection between the fixing plate and the insertion port.

[0011] Furthermore, the driving device includes a threaded rod threadedly connected in the first threaded groove and a triangular block fixed in the fixing hole away from the inner wall of the sliding groove. The sliding rod has a mounting groove on the side wall near the first threaded groove, and a second inclined surface is formed on the edge where the inner wall of the mounting groove away from the compression spring intersects with the side wall of the sliding rod near the first threaded groove.

[0012] By adopting the above technical solution, when the sliding rod is connected to the fixed hole under the action of the compression spring, the operator only needs to connect the threaded rod to the first threaded groove and rotate the threaded rod to move the threaded rod closer to the sliding rod, thereby pressing the threaded rod against the second inclined surface. This allows the sliding rod to continue moving upward under the action of the threaded rod, and then press the sliding rod against the inclined surface of the triangular block, thereby squeezing the inner wall of the fixed hole and improving the tightness of the connection between the sliding rod and the fixed hole.

[0013] Furthermore, the sidewall of the triangular block near the insertion opening is flush with the inner wall of the fixing hole.

[0014] Furthermore, a third inclined surface is provided on the edge where the inner wall of the mounting groove near the compression spring intersects with the side wall of the sliding rod near the first threaded groove, and a second threaded groove matching the threaded rod is provided on the inner wall of the sliding groove.

[0015] By adopting the above technical solution, when workers need to inspect the fixing plate, they must separate the sliding rod from the fixing hole. At this time, workers need to separate the threaded rod from the first threaded groove, connect the threaded rod to the second threaded groove, and rotate the threaded rod. This will move the threaded rod closer to the sliding rod and press against the third inclined surface, causing the sliding rod to move downwards under the action of the threaded rod and completely into the sliding groove. Furthermore, workers only need to pull the fixing plate to separate it from the insertion port.

[0016] Furthermore, a silicone sheet is fixed to the side wall of the fixing plate to improve its stability.

[0017] Furthermore, a handle is fixed to the end of the threaded rod to reduce the difficulty for workers to turn the threaded rod.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. In this application, when the worker needs to install the sealing tape, the worker needs to connect the fixing plate and the insertion port and push the fixing plate, which will automatically keep the fixing plate stable under the action of the sliding rod. Furthermore, the worker only needs to turn on the drive device, which will allow the sliding rod to continue to move upward under the action of the drive device, thereby improving the tightness of the connection between the fixing plate and the insertion port, thus reducing the probability of slight shaking of the fixing plate when subjected to external force;

[0020] 2. In this application, when the operator connects the fixing plate to the insertion port, the first inclined surface abuts against the edge of the insertion port, thereby causing the sliding rod to move completely into the sliding groove under the action of the fixing plate. Subsequently, when the sliding groove is aligned with the fixing hole, the sliding rod connects with the fixing hole under the action of the compression spring, thus initially stabilizing the sliding rod. Furthermore, the operator only needs to activate the drive device to allow the sliding rod to continue moving upward under the action of the drive device, thereby improving the tightness of the connection between the sliding rod and the fixing hole, and further improving the tightness of the connection between the fixing plate and the insertion port. Furthermore, the operator only needs to close the two PVC window bodies to allow the two sealing strips on the two PVC window bodies to abut against each other, thereby improving the sealing performance of the PVC window bodies.

[0021] 3. In this application, when the sliding rod is connected to the fixed hole under the action of the compression spring, the operator only needs to connect the threaded rod to the first threaded groove and rotate the threaded rod to move the threaded rod closer to the sliding rod, thereby making the threaded rod press against the second inclined surface, so that the sliding rod continues to move upward under the action of the threaded rod, thereby making the sliding rod press against the inclined surface of the triangular block, thereby making the sliding rod squeeze the inner wall of the fixed hole, thus improving the tightness of the connection between the sliding rod and the fixed hole.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-5 As shown in the illustration, this application discloses a weather-resistant sealing strip structure for aluminum-plastic windows and doors, including a PVC window body 1, a fixing plate 2, a sealing plate 21, a sealing strip 3, a limiting component 4, and a silicone sheet 8. An insertion port 11 is provided on the side wall of the PVC window body 1. The fixing plate 2 is a plate-shaped structure and is slidably disposed within the insertion port 11. The sealing plate 21 is a plate-shaped structure and is disposed on the side wall of the fixing plate 2, with the sealing strip 3 connected to the sealing plate 21.

[0030] Sliding grooves 31 are provided on both the upper and lower surfaces of the fixed plate 2. A limiting component 4 is disposed on the fixed plate 2 to limit its movement. The limiting component 4 includes a sliding rod 41, a compression spring 42, and a driving device 5. The sliding rod 41 is a rectangular rod structure and is slidably disposed within the sliding groove 31. One end of the compression spring 42 is fixed to the bottom surface of the sliding rod 41, and the other end of the compression spring 42 is fixed to the inner bottom wall of the sliding groove 31. Fixing holes 43 that match the sliding rod 41 are provided on both the inner top and inner bottom walls of the insertion port 11.

[0031] A first threaded groove 6 is formed on the inner wall of the sliding groove 31, and a first inclined surface 61 is formed on the edge of the sliding rod 41 where it intersects with the side wall away from the compression spring 42 and the side wall away from the first threaded groove 6. When the operator connects the fixing plate 2 to the insertion port 11, the first inclined surface 61 abuts against the edge of the insertion port 11, thereby allowing the sliding rod 41 to move completely into the sliding groove 31 under the action of the fixing plate 2. Subsequently, when the sliding groove 31 is aligned with the fixing hole 43, the sliding rod 41 connects with the fixing hole 43 under the action of the compression spring 42, thereby initially stabilizing the sliding rod 41. Furthermore, the operator only needs to activate the drive device 5 to allow the sliding rod 41 to continue moving upward under the action of the drive device 5, thereby improving the tightness of the connection between the sliding rod 41 and the fixing hole 43, and further improving the tightness of the connection between the fixing plate 2 and the insertion port 11.

[0032] A driving device 5 is mounted on the fixed plate 2 and is used to drive the sliding rod 41. The driving device 5 includes a threaded rod 51 and a triangular block 52. The threaded rod 51 is threaded into the first threaded groove 6. The triangular block 52 is a triangular block structure and is fixed to the inner wall of the fixed hole 43 away from the sliding groove 31. The side wall of the triangular block 52 near the opening of the insertion port 11 is flush with the inner wall of the fixed hole 43. A mounting groove 53 is provided on the side wall of the sliding rod 41 near the first threaded groove 6. A second inclined surface 54 is provided on the edge where the inner wall of the mounting groove 53 away from the compression spring 42 intersects with the side wall of the sliding rod 41 near the first threaded groove 6.

[0033] When the sliding rod 41 is connected to the fixed hole 43 under the action of the compression spring 42, the operator only needs to connect the threaded rod 51 to the first threaded groove 6 and rotate the threaded rod 51 to move the threaded rod 51 closer to the sliding rod 41, thereby pressing the threaded rod 51 against the second inclined surface 54. As a result, the sliding rod 41 continues to move upward under the action of the threaded rod 51, thereby pressing the sliding rod 41 against the inclined surface of the triangular block 52, thereby squeezing the inner wall of the fixed hole 43, thus improving the tightness of the connection between the sliding rod 41 and the fixed hole 43.

[0034] A third inclined surface 7 is provided on the edge where the inner wall of the mounting groove 53 near the compression spring 42 intersects with the side wall of the sliding rod 41 near the first threaded groove 6, and a second threaded groove 71 matching the threaded rod 51 is provided on the inner wall of the sliding groove 31.

[0035] When the worker needs to inspect the fixing plate 2, the worker needs to separate the sliding rod 41 from the fixing hole 43. At this time, the worker needs to separate the threaded rod 51 from the first threaded groove 6, connect the threaded rod 51 to the second threaded groove 71, and rotate the threaded rod 51. This will move the threaded rod 51 towards the sliding rod 41 and press it against the third inclined surface 7, thereby causing the sliding rod 41 to move downward under the action of the threaded rod 51 and move completely into the sliding groove 31. Furthermore, the worker only needs to pull the fixing plate 2 to separate the fixing plate 2 from the insertion port 11.

[0036] To improve the stability of the fixing plate 2, a silicone sheet 8 is fixed to the side wall of the fixing plate 2.

[0037] To reduce the difficulty for workers to rotate the threaded rod 51, a handle 9 is fixed to the end of the threaded rod 51.

[0038] The working principle of the weather-resistant sealing strip structure for aluminum-plastic doors and windows in this embodiment is as follows: When the worker needs to install the sealing strip 3, the worker needs to connect the fixing plate 2 with the insertion port 11 and push the fixing plate 2, which will automatically keep the fixing plate 2 stable under the action of the sliding rod 41. Furthermore, the worker only needs to turn on the driving device 5, which will allow the sliding rod 41 to continue to move upward under the action of the driving device 5, thereby improving the tightness of the connection between the fixing plate 2 and the insertion port 11, thus reducing the probability of slight shaking when the fixing plate 2 is subjected to external force. Furthermore, the worker only needs to close the two PVC window bodies 1, which will cause the two sealing strips 3 on the two PVC window bodies 1 to abut against each other, thereby improving the sealing performance of the PVC window bodies 1.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
