Description

Technical Field

[0001] This utility model relates to the field of door and window installation technology, and in particular to a quick-installation clip for aluminum-plastic doors and windows. Background Technology

[0002] Aluminum-plastic composite doors and windows are a general term for modern doors and windows that combine the strength of metal with the thermal insulation performance of plastic. They include types such as aluminum alloy, PVC and aluminum-plastic composite. They have high heat insulation and sound insulation performance and are widely used in residential buildings and buildings in extreme climates. The installation steps of the window frame mainly include the assembly of the frame and the fixing of the frame to the wall.

[0003] When assembling traditional aluminum-plastic door and window frames, auxiliary components such as connectors are first used to splice the entire frame together to pre-position the frame. Then, wrenches or screwdrivers are used with screws to tighten the connectors at the four corners of the frame one by one. The operation is cumbersome and does not improve the speed of door and window assembly. Utility Model Content

[0004] To solve the above problems, this utility model provides a quick-installation clip for aluminum-plastic doors and windows.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-installation buckle for aluminum-plastic doors and windows, comprising two first frames and two second frames disposed between the two first frames, the two second frames being symmetrically arranged about the middle of the first frames, transparent glass being disposed on both the two first frames and the two second frames, and T-shaped locking plates being detachably connected to both ends of the second frames, and locking slots for inserting into the corresponding locking plates being provided at both ends of the first frames, and a buckle assembly for automatically locking the locking plate to the second frame on each locking plate.

[0006] By adopting the above technical solution, when assembling doors and windows, firstly, insert the locking plates at both ends of one of the second frames into the corresponding slots on the two first frames, until the locking plates can no longer move. At this time, the buckle assembly automatically locks the locking plates and the second frame. Then, fix the other second frame to the two first frames in the same way. This eliminates the cumbersome operation of connecting the first and second frames with connectors and then using tools and screws to fasten the first and second frames, which is required in the existing technology. This improves the speed of assembling door and window frames.

[0007] Furthermore, the card plate has an installation groove on the side wall near the second frame. The buckle assembly includes a buckle strip that is fixed in the installation groove and has elasticity, and a buckle block that is fixed on the side wall of the card groove and the buckle strip respectively. The buckle strip has an L-shaped structure, and the horizontal section of the buckle strip abuts against the buckle block.

[0008] By adopting the above technical solution, during the process of inserting the card plate into the card slot, the buckle bar moves along the card slot. The buckle bar will first contact the buckle block. Since the buckle bar is made of elastic material, the buckle bar deforms under force and moves along the side wall of the buckle block until the card plate can no longer move. As the buckle block releases the restriction on the buckle bar, the buckle bar deforms in the opposite direction and resets. The side wall of the horizontal section of the buckle bar away from the middle of the first frame fits against the side wall of the buckle block near the middle of the first frame. The buckle block limits the buckle bar, thereby fixing the card plate in the card slot, thus achieving the purpose of automatic locking between the card plate and the second frame.

[0009] Furthermore, limit strips are fixed to both ends of the two second frames, and limit grooves are provided on the side walls of the two first frames to be inserted and connected to the corresponding limit strips.

[0010] By adopting the above technical solution, the setting of the limiting strip and the limiting groove improves the stability of the connection between the first frame and the second frame.

[0011] Furthermore, a limiting plate is fixed on the limiting strip, and a limiting groove communicating with the limiting strip is opened on the second frame, and the limiting plate is inserted into the corresponding limiting groove.

[0012] By adopting the above technical solution, the setting of the limiting plate and the limiting groove improves the stability when the limiting strip and the limiting groove are connected.

[0013] Furthermore, the card plate is provided with an L-shaped and elastic buckle plate, and the end face of the first frame is provided with a connecting through hole extending to the other end of the first frame. The buckle plate is located inside the corresponding connecting through hole, and a positioning groove is provided in the connecting through hole to engage with the vertical section of the buckle plate.

[0014] By adopting the above technical solution, the good limiting effect between the positioning groove and the buckle plate ensures the stability of the connection between the buckle plate and the second frame.

[0015] Furthermore, the connecting through hole and the card plate are connected by a reinforcing block, and the reinforcing block is plugged into the connecting through hole.

[0016] Furthermore, a first inclined surface is provided at the junction between the end of the buckle plate near the middle of the first frame and the end of the buckle plate near the positioning groove.

[0017] By adopting the above technical solution, the reinforcing block is inserted into the connecting through hole, which in turn drives the buckle plate connected to the reinforcing block to move. The first inclined surface of the buckle plate contacts the inner wall of the connecting through hole, and the buckle plate deforms under force until the buckle plate moves to the position of the positioning groove. Since the connecting through hole releases the restriction on the buckle plate, the buckle plate deforms in the opposite direction and resets. Finally, the vertical section of the buckle plate is inserted into the positioning groove, thereby completing the operation of fixing the buckle plate to the second frame. The setting of the first inclined surface makes it easy for the buckle plate to pass into the connecting through hole.

[0018] Furthermore, a second inclined surface is provided at the junction of the end of the card plate near the middle of the first frame and the side walls on both sides of the card plate, and the distance between the two second inclined surfaces gradually decreases from the end face of the first frame to the middle of the first frame.

[0019] By adopting the above technical solution, the setting of the second inclined surface facilitates the insertion of the card plate into the card slot.

[0020] In summary, the present invention has the following beneficial effects: In this application, by improving the existing technical structure, the cumbersome operation of connecting the first frame and the second frame with connectors and then fastening the first frame and the second frame with tools and screws is eliminated, thereby improving the assembly speed of door and window frames.

[0023] 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.

[0024] like Figure 1-6 As shown in the figure, this application discloses a quick-installation buckle for aluminum-plastic doors and windows, including a first frame 1, a second frame 2, and transparent glass. The first frame 1 has two members. The second frame 2 has two members, each positioned between the two first frame 1 members. The transparent glass is mounted on both the two first frame 1 members and the two second frame 2 members. Both ends of the second frame 2 are detachably connected to T-shaped clamping plates 3. The clamping plates 3 have mounting grooves 6 on their sidewalls near the second frame 2. Both ends of the first frame 1 have corresponding clamping slots 4 for insertion into the clamping plates 3. When assembling doors and windows, firstly, insert the clips 3 at both ends of one of the second frames 2 into the corresponding slots 4 on the two first frames 1, until the clips 3 can no longer move. At this time, the buckle assembly 5 automatically locks the clips 3 and the second frame 2. Then, fix the other second frame 2 to the two first frames 1 in the same way. This eliminates the cumbersome operation of connecting the first frame 1 and the second frame 2 with connectors and then fastening the first frame 1 and the second frame 2 with tools and screws, which is required by existing technology. This improves the speed of assembling door and window frames.

[0025] The latching assembly 5 is disposed on the latching plate 3, and the number of latching assemblies 5 is equal to the number of latching plates 3, with each assembly corresponding to the other. The latching assembly 5 is used to automatically lock the latching plate 3 to the second frame 2. The latching assembly 5 includes a latching strip 51 and a latching block 52. The latching strip 51 is fixed in the mounting groove 6 and is elastic. The latching strip 51 has an L-shaped structure, and the latching block 52 is fixed in the latching groove 4 on the side wall corresponding to the latching strip 51. The horizontal section of the latching strip 51 abuts against the latching block 52. During the process of inserting the card plate 3 into the card slot 4, the buckle strip 51 moves along the card slot 4. The buckle strip 51 will first contact the buckle block 52. Since the buckle strip 51 is made of elastic material, the buckle strip 51 deforms under force and moves along the side wall of the buckle block 52 until the card plate 3 can no longer move. Since the buckle block 52 releases the restriction on the buckle strip 51, the buckle strip 51 deforms in the opposite direction and resets. The side wall of the horizontal section of the buckle strip 51 away from the middle of the first frame 1 fits against the side wall of the buckle block 52 near the middle of the first frame 1. The buckle block 52 limits the buckle strip 51, thereby fixing the card plate 3 in the card slot 4, thus achieving the purpose of automatic locking between the card plate 3 and the second frame 2.

[0026] Limiting strips 7 are fixed to both ends of the two second frames 2, and limiting grooves 8 are provided on the side walls of the two first frames 1 to connect with the corresponding limiting strips 7. The setting of limiting strips 7 and limiting grooves 8 improves the stability of the connection between the first frames 1 and the second frames 2.

[0027] A limiting plate 9 is fixed on the limiting strip 7, and a limiting groove 10 communicating with the limiting strip 7 is opened on the second frame 2. The limiting plate 9 is inserted into the corresponding limiting groove 10. The setting of the limiting plate 9 and the limiting groove 10 improves the stability when the limiting strip 7 and the limiting groove 8 are connected.

[0028] The card plate 3 is provided with an L-shaped, elastic snap-fit ​​plate 11. A connecting through hole 12 extending to the other end of the first frame 1 is provided through the end face of the first frame 1. The snap-fit ​​plate 11 is located inside the corresponding connecting through hole 12. A positioning groove 13 is provided in the connecting through hole 12 to engage with the vertical section of the snap-fit ​​plate 11. The good limiting effect between the positioning groove 13 and the snap-fit ​​plate 11 ensures the stability of the connection between the card plate 3 and the second frame 2.

[0029] The connecting through hole 12 is connected to the card plate 3 by a reinforcing block 14, and the reinforcing block 14 is plugged into the connecting through hole 12.

[0030] A first inclined surface is provided at the junction between the end of the buckle plate 11 near the middle of the first frame 1 and the end of the buckle plate 11 near the positioning groove 13. When the reinforcing block 14 is inserted into the connecting through hole 12, the buckle plate 11 connected to the reinforcing block 14 is moved. The first inclined surface on the buckle plate 11 contacts the inner wall of the connecting through hole 12, and the buckle plate 11 is deformed under force until the buckle plate 11 moves to the position of the positioning groove 13. Since the connecting through hole 12 releases the restriction on the buckle plate 11, the buckle plate 11 deforms in the opposite direction and resets. Finally, the vertical section of the buckle plate 11 is inserted into the positioning groove 13, thereby completing the operation of fixing the buckle plate 3 and the second frame 2. The setting of the first inclined surface makes it easy for the buckle plate 11 to pass into the connecting through hole 12.

[0031] A second inclined surface is provided at the junction of the end of the card plate 3 near the middle of the first frame 1 and the side walls on both sides of the card plate 3. The distance between the two second inclined surfaces gradually decreases from the end face of the first frame 1 to the middle of the first frame 1. The second inclined surface is provided to facilitate the card plate 3 to pass into the card slot 4.

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.
