Description

Technical Field

[0001] This utility model relates to the technical field of door and window installation, and in particular to a connection device for quick installation and disassembly of door and window profiles. Background Technology

[0002] Currently, the installation of door and window profiles requires pre-cutting slits in the profiles to accommodate connectors. These connectors are designed to ensure the stability of the entire door and window structure, securely linking various parts of the profile (such as the window frame, sash, atrium, and transmission rod). During installation, the connectors are inserted through the slits into the profile grooves before assembling the various parts. This not only affects the aesthetics of the product but may also damage the structure and sealing of the door and window profiles. If the connectors do not achieve a good seal after installation, rainwater can easily seep in, affecting the waterproof performance of the doors and windows. Replacing the connectors in this case requires manually cutting new slits in the profiles to remove the old connectors and install the new ones, which is cumbersome and can easily cause secondary damage to the structure and sealing of the door and window profiles. Furthermore, over time, the material around the pre-cut openings may age or develop micro-cracks, making the doors and windows prone to breakage when subjected to external impacts (such as during heavy rain or storms), posing a significant safety hazard.

[0003] To overcome the technical problems of difficult installation and disassembly of existing connecting devices, which easily damage the structure and sealing of door and window profiles, this utility model provides a quick-installation and quick-disassembly connecting device for door and window profiles, including a connecting seat. The connecting seat includes a first positioning member and a second positioning member. The first positioning member has a limiting cavity with an opening. The second positioning member has an elastic connecting section and an operating section connected to the elastic connecting section. The elastic connecting section extends into the limiting cavity, and the operating section is located outside the opening. The second positioning member has a first position and a second position relative to the first positioning member. The operating section of the second positioning member located in the first position is used to connect to one of the contact walls of the profile groove, and the operating section of the second positioning member located in the second position is separated from the contact wall.

[0004] Furthermore, the elastic connecting segment has a C-shaped structure, with claws at both ends that can extend and expand, and the claws are connected to the inner wall of the limiting cavity.

[0005] Furthermore, the first positioning member also has a limiting wall located in the limiting cavity, the limiting wall restricting the elastic connecting segment from disengaging from the limiting cavity.

[0006] Furthermore, the operating section has a hook end that engages with the limiting wall.

[0007] Furthermore, the operating segment has an antenna and a protrusion, the antenna is located at the top of the protrusion, the antenna and the protrusion are fixedly connected, and the antenna has an operating gap with the outer edge of the opening.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] Please refer to Figures 1 to 7 A quick-installation and quick-disassembly connection device for door and window profiles includes a connecting seat 101. The connecting seat 101 includes a first positioning member 1 and a second positioning member 2. The first positioning member 1 has a limiting cavity 11 with an opening 111. The second positioning member 2 has an elastic connecting section 21 and an operating section 22 connected to the elastic connecting section 21. The elastic connecting section 21 extends into the limiting cavity 11, and the operating section 22 is located outside the opening 111. The second positioning member 2 has a first position and a second position relative to the first positioning member 1. When the second positioning member 2 is in the first position, the operating section 22 is used to connect to one of the contact walls 5 of the profile groove. When the second positioning member 2 is in the second position, the operating section 22 is separated from the contact wall 5.

[0027] In this technical solution, the cooperation between the first positioning member 1 and the second positioning member 2 of the connecting seat 101 enables the connecting device to be quickly positioned and fixed in the profile groove. The first positioning member 1 is connected to the second positioning member 2. The first positioning member 1 has a limiting cavity 11 with an opening 111 to provide space for the elastic connecting section 21 of the second positioning member 2. The elastic connecting section 21 of the second positioning member 2 extends into the limiting cavity 11 and can change position within the limiting cavity 11. The operating section 22 of the second positioning member 2 is located outside the opening 111 of the limiting cavity 11. The operating section 22 is used to engage with the contact wall 5 of the profile groove. By changing the operating section 22, the second positioning member 2 can be positioned relative to the profile groove. The first positioning element 1 can change position. During installation, one end of the first positioning element 1 is engaged with one of the contact walls 5 of the profile groove, the second positioning element 2 is in the first position, and the operating section 22 is engaged with the other contact wall 5 of the profile groove, so that the connecting device can be stably installed in the profile groove without the need to pre-cut on the profile groove, thus avoiding the defect of the prior art that requires pre-cutting to install the connecting device. When the second positioning element 2 is in the second position, the operating section 22 is separated from the contact wall 5 of the profile groove, and the first positioning element 1 is also separated from the contact wall 5 of the profile groove. The connecting device can be detached from the profile groove for replacement, solving the defect of the difficulty in disassembling and replacing the connecting device in the prior art, and giving users a good product experience.

[0028] It is worth noting that the assembly relationship between the first positioning component 1 and the second positioning component 2 is determined by... Figure 4 As shown, the first positioning member 1 also has a limiting wall 12, which is located in the limiting cavity 11 and restricts the elastic connecting section 21 from disengaging from the limiting cavity 11. In this technical solution, the elastic connecting section 21 is elastic, and the limiting wall 12 is located in the limiting cavity 11. The limiting wall 12 is vertically set on the bottom wall surface of the limiting cavity 11. The elastic connecting section 21 extends from the opening 111 into the limiting cavity 11 until the hook end 22a of the operating section 22 is fastened to the limiting wall 12, realizing the mutual connection between the first positioning member 1 and the second positioning member 2. The second positioning member 2 is not easy to fall off, and the structure is stable. The second positioning member 2 can realize the position change in the limiting cavity 11. When it is in the first position, the hook end 12 is squeezed by the contact wall 5 of the profile groove and moves away from the limiting wall 12. At this time, the two ends of the elastic connecting section 21 are squeezed and contracted in the limiting cavity 11. When it is in the second position, the two ends of the elastic connecting section 21 expand in the limiting cavity 11, the operating section 22 moves away from the limiting cavity 11, and the hook end 22a of the operating section 22 is fastened to the limiting wall 12, realizing the elastic change of the elastic connecting section 21. The structure is simple and stable.

[0029] It should be noted that in this technical solution, the elastic connecting section 21 and the operating section 22 of the second positioning component 2 are integrally set and formed into a whole structure through injection molding, ensuring the stability and reliability of the connection. The elastic connecting section 21 has a C-shaped structure and has claws 21a that can extend and retract. In this embodiment, there are two claws 21a, which are arranged opposite to each other. When the claws 21a retract in the limiting cavity 11 (i.e., the elastic connecting section 21 is completely located in the limiting cavity 11), the operating section 22... It is one of the contact walls 5 that is snapped into the profile groove, that is, the second positioning member 2 is located in the first position; while the claw 21a expands in the limiting cavity 11 (that is, the claw 21a of the elastic connecting section 21 expands towards the inner wall surface of the limiting cavity 11 in the limiting cavity 11 and abuts against the inner wall surface of the limiting cavity 11, the part of the elastic connecting section 21 away from the claw 21a extends out of the opening 111, and the hook end 22a is fastened to the limiting wall (12)), the operating section 22 has separated from the contact wall 5, and the second positioning member 2 is located in the second position.

[0030] The operation segment 22 is used to determine whether the second positioning element 2 has changed position. A specific embodiment is provided below. Figure 1 and Figure 4 As shown, the operating segment 22 has an antenna 221 and a protrusion 222. The antenna 221 is located at the top of the protrusion 222. The antenna 221 and the protrusion 222 are fixedly connected. The outer edge of the opening 111 of the antenna 221 has an operating gap 3. In this embodiment, the antenna 221 passes through the opening 111 and is fixed on the outer edge of the opening 111. The antenna 221 and the outer edge of the opening 111 form an operating gap 3. The antenna 221 can reciprocate along the length of the operating gap 3. The second positioning member 2 can move smoothly during the movement, avoiding jamming and exhibiting high flexibility. When the second positioning member 2 is in the first position, the protrusion 222 engages with the contact wall 5 of the profile groove, the antenna 221 moves toward the operating gap 3, the hook end 22a is squeezed away from the limiting wall 12, and the claws 21a of the elastic connecting section 21 are restricted by the wall of the limiting cavity 11, achieving contraction. When the second positioning member 2 is in the second position, the protrusion 222 separates from the contact wall 5 of the profile groove, the claws of the elastic connecting section 21 regain their elasticity, and expand within the limiting cavity 11 until the hook end 22a engages with the limiting wall 12, thereby achieving a positional change of the second positioning member 2 relative to the first positioning member 1. Preferably, by Figure 1 and Figure 4As shown, the protrusion 222 has an inclined surface 2221. The inclined surface 2221 protrudes outward toward one end of the antenna 221. The outwardly protruding part is inclined downward. When installing the connecting device, one end of the connecting seat 101 is fixed on one of the contact walls 5 of the profile groove. Then, the connecting device is pressed, and the inclined surface 2221 gradually abuts against the other contact wall 5 of the profile groove, guiding the antenna 221 to move toward the operating gap 3. The outwardly protruding part of the protrusion 222 moves toward the operating gap 3 along with the antenna 221, guiding the entire inclined surface 2221 to move better along the direction of the contact wall 5 of the profile groove, so that the protrusion 222 can be better engaged on the contact wall 5 without jamming, resulting in high installation efficiency and stable structure.

[0031] Among them, by Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the first positioning member 1 also has a snap-fit ​​wall 13, which is located at the end of the first positioning member 1 away from the limiting cavity 11 and is used to snap onto another contact wall 5 of the profile groove. The snap-fit ​​wall 13 has an L-shaped structure, which facilitates snapping onto the contact wall 5 of the profile groove. It should be noted that the shape and structure of the contact wall 5 of the profile groove are conventional technical means and will not be described in detail here. When the connecting device is installed, the snap-fit ​​wall 13 of the first positioning member 1 snaps into one of the contact walls 5 of the profile groove. At this time, one end of the connecting device of the entire structure is inclined upward from the contact wall 5 of the profile groove, while the other end of the connecting device is against the other contact wall 5 of the profile groove and is not fixedly installed in the inner cavity of the profile groove. At this time, the inclined surface 2221 of the protrusion 222 gradually enters the inner cavity of the profile groove, and the inclined surface 2221 of the protrusion 222 contacts the other contact wall 5 of the profile groove. The adjusting angle 221 moves towards the operating gap 3 until the inclined surface 2221 can contact the contact wall 5. At this time, the external force pressing on the connecting device is removed, the angle 221 moves away from the operating gap 3, and the protrusion 222 pops out and snaps into the contact wall 5 of the profile groove. The connecting device can be matched and installed in the profile groove without considering the pre-cut installation of the connecting device.

[0032] For stable installation of the structure, by Figures 2 to 4As shown, the connecting device also includes a locking element 103. The connecting seat 101 has a vertically penetrating locking hole 104, and the locking element 103 is inserted and fixed in the locking hole 104. In this embodiment, the locking element 103 is a locking pin, with one end passing through the locking hole 104 and the other end located at the top of the locking hole 104 for adjusting the position of the locking pin. The locking pin is riveted to the connecting seat 101. When the connecting device is connected to the transmission rod of the door or window, the door or window can be adjusted to be closed or open by the locking pin. When the door or window is closed or opened, the transmission rod moves, driving the connecting device to move. If it is found that the door or window is difficult to push, the locking pin can be loosened or tightened to allow the connecting device to move with the transmission rod for easy adjustment, ensuring smooth closing or opening of the installed door or window and providing users with a good product experience.

[0033] Furthermore, the assembly relationship between the transmission rod and the connecting device is determined by... Figure 3 and Figure 7 As shown, the connecting device also includes a connecting block 102 and a fastener 106. The connecting block 102 is fixedly installed on the end of the connecting seat 101 away from the locking member 103. The connecting block 102 has a through-hole 107. The left and right sides of the connecting block 102 are bent downward to form an inner cavity 108 for fitting the transmission rod 4. The connecting block 102 has a foolproof protrusion 105 on the side facing the inner cavity 108. The foolproof protrusion 105 fits into the foolproof groove 41 of the transmission rod 4. In this embodiment, the fastener 106 is a fastening screw. The fastening screw passes through the fastening hole 107 and is fixedly connected to the transmission rod 4 to prevent the transmission rod 4 from shifting. The transmission rod 4 for installing doors and windows is a conventional technical means and will not be described in detail here. In this embodiment, the transmission rod 4 is inserted into the inner cavity 108 of the connecting block 102, and the connecting block 102 is provided with a foolproof protrusion 105 on the side facing the inner cavity 108. The foolproof protrusion 105 can be adapted to the foolproof groove 41 of the transmission rod 4 to guide the transmission rod 4 to move along the length direction of the profile groove and prevent the transmission rod 4 from being misaligned in the profile groove.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
