Description

Technical Field

[0001] The present invention relates to the technical field of door and window installation, and particularly to a connecting device for quick installation and disassembly of door and window profiles. Background Art

[0002] At present, for the installation of door and window profiles, notches need to be pre-opened on the door and window profiles to accommodate the connecting pieces. And this connecting device is to ensure the stability of the entire door and window structure. This connecting device is used to firmly connect various parts of the door and window profiles (such as window frames, window sashes, atriums, transmission rods, etc.). During installation, the connecting device needs to be inserted into the profile groove of the door and window profiles through the notch, and then various parts of the door and window profiles (such as window frames, window sashes, atriums, transmission rods, etc.) are assembled. This notch not only affects the aesthetics of the product, but also may damage the structural integrity and sealing performance of the door and window profiles. If the connecting device does not achieve a good sealing effect after installation, it is easy to cause rainwater to seep in, affecting the waterproof performance of the doors and windows. At this time, to replace the connecting device, it is necessary to manually open another notch on the door and window profiles to remove the old connecting device and install a new one, which is troublesome to operate and prone to secondary damage to the structural integrity and sealing performance of the door and window profiles. In addition, over time, the materials around the pre-opened notch may age or develop tiny cracks. When the door and window are impacted by external forces (such as during heavy rain and strong wind weather), they are prone to breakage, and the existing potential safety hazards cannot be ignored. Summary of the Invention

[0003] To overcome the technical problems in the prior art that the installation and disassembly of the connecting device are difficult and prone to damage the structural integrity and sealing performance of the door and window profiles, the present invention provides a connecting device for quick installation and disassembly of 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 is provided with a limiting cavity having 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 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 in the second position is separated from the contact wall.

[0004] Further, the elastic connecting section has a C-shaped structure, and both ends thereof are provided with claw teeth having telescopic and expanding functions. The claw teeth are connected to the inner wall surface of the limiting cavity.

[0005] Further, the first positioning member further has a limiting wall located in the limiting cavity. The limiting wall restricts the elastic connecting section from detaching from the limiting cavity.

[0006] Further, the operating section has a hooked end which is snap-fitted to the limiting wall.

[0007] Further, the operating section has an antenna and a bump. The antenna is located at the top end of the bump. The antenna and the bump are fixedly connected. There is an operating gap between the antenna and the outer edge of the opening.

[0008] Further, the bump has an inclined surface which protrudes outward towards one end of the antenna. The outward protruding part is inclined downward.

[0009] Further, the first positioning member further has a clamping wall which is located at the end of the first positioning member away from the limiting cavity and is used for clamping to another contact wall of the profile groove.

[0010] Further, the clamping wall is in an L-shaped structure.

[0011] Further, the connecting device further includes a locking member. The connecting seat is provided with a locking hole penetrating up and down. The locking member is inserted and fixed in the locking hole.

[0012] Further, the connecting device further has a connecting block and a fastener. The connecting block is fixedly installed at the end of the connecting seat away from the locking member. The connecting block is provided with a fastening hole penetrating up and down. The left and right sides of the connecting block are bent downward to form an inner cavity for adapting to the transmission rod. The connecting block is fixedly connected to the transmission rod through the fastener passing through the fastening hole. An anti-fooling convex point is provided on one side of the connecting block facing the inner cavity. The anti-fooling convex point is adapted to the anti-fooling groove of the transmission rod. Beneficial effects

The first positioning member is connected to the second positioning member. The first positioning member is provided with a limiting cavity having an opening to provide a moving space for the elastic connecting section of the second positioning member. The elastic connecting section of the second positioning member extends into the limiting cavity, and the elastic connecting section can achieve position changes within the limiting cavity. The operating section of the second positioning member is located outside the opening of the limiting cavity. The operating section is used to be clamped to the contact wall of the profile groove. By changing the operating section, the second positioning member can generate position changes relative to the first positioning member. During installation, one end of the first positioning member is clamped to one contact wall of the profile groove, the second positioning member is in the first position, and the operating section is clamped to the other contact wall of the profile groove, realizing the installation of the connecting device in the profile groove opening without pre-setting a notch on the profile groove, avoiding the defect in the prior art that a notch needs to be pre-set for installing the connecting device.

[0017] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 to 7 , a connection device for quick installation and disassembly of door and window profiles, including a connection seat 101. The connection seat 101 includes a first positioning member 1 and a second positioning member 2. The first positioning member 1 is provided with a limiting cavity 11 having an opening 111; the second positioning member 2 has an elastic connection section 21 and an operating section 22 connected to the elastic connection section 21. The elastic connection 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.

[0019] In this technical solution, the mutual 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 is provided with a limiting cavity 11 having an opening 111 to provide a moving 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 the elastic connecting section 21 can change its 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 be clamped to the contact wall 5 of the profile groove. By changing the operating section 22, the second positioning member 2 can change its position relative to the first positioning member 1. During installation, one end of the first positioning member 1 is clamped to one of the contact walls 5 of the profile groove, the second positioning member 2 is in the first position, and the operating section 22 is clamped to the other contact wall 5 of the profile groove, realizing the stable installation of the connecting device in the profile groove opening without pre-setting a notch on the profile groove, avoiding the defect in the prior art that a notch needs to be pre-set to install the connecting device. When the second positioning member 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 member 1 is also separated from the contact wall 5 of the profile groove. The connecting device can be detached from the profile groove opening for replacement, solving the defect in the prior art that it is difficult to disassemble and replace the connecting device, and giving users a good product experience.

[0020] It should be noted that the assembly relationship between the first positioning member 1 and the second positioning member 2 is shown by Figure 4 The first positioning member 1 further has a limiting wall 12. The limiting wall 12 is located in the limiting cavity 11. The limiting wall 12 restricts the elastic connecting section 21 from detaching from the limiting cavity 11. In this technical solution, the elastic connecting section 21 has elasticity. The limiting wall 12 is located in the limiting cavity 11 and is vertically arranged on the bottom wall surface of the limiting cavity 11. The elastic connecting section 21 extends into the limiting cavity 11 from the opening 111 until the hook end 22a of the operating section 22 is buckled on 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 change its position in the limiting cavity 11. When 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, both ends of the elastic connecting section 21 are squeezed and contracted in the limiting cavity 11. When in the second position, both 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 buckled on the limiting wall 12, realizing the elastic change of the elastic connecting section 21. The structure is simple and stable.

[0021] It should be noted that the elastic connection section 21 and the operation section 22 of the second positioning member 2 in this technical solution are integrally provided and form an integral structure through an injection molding process to ensure the stability and reliability of the connection. The elastic connection section 21 has a C-shaped structure and has pawls 21a that can be telescoped and expanded. In this embodiment, the number of the pawls 21a is two, and the two pawls are arranged oppositely. When the pawls 21a contract in the limiting cavity 11 (that is, the elastic connection section 21 is completely located in the limiting cavity 11), the operation section 22 is clamped to one of the contact walls 5 of the profile groove, that is, the second positioning member 2 is located at the first position; when the pawls 21a expand in the limiting cavity 11 (that is, the pawls 21a of the elastic connection section 21 expand towards the inner wall surface of the limiting cavity 11 in the limiting cavity 11, abut against the inner wall surface of the limiting cavity 11, and the part of the elastic connection section 21 away from the pawls 21a extends out of the opening 111, and the hook end 22a is buckled on the limiting wall (12)), the operation section 22 has been separated from the contact wall 5, and the second positioning member 2 is located at the second position.

[0022] And the part of the operation section 22 for driving the second positioning member 2 to change its position, the specific embodiment is composed of Figure 1 and Figure 4 As shown, the operation section 22 has an antenna 221 and a convex block 222. The antenna 221 is located at the top of the convex block 222. The antenna 221 and the convex block 222 are fixedly connected. The antenna 221 has an operation gap 3 with the outer edge of the opening 111. 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 operation gap 3. The antenna 221 can reciprocate back and forth along the length direction of the operation gap 3. The second positioning member 2 can move smoothly during the movement, avoiding jamming and having high flexibility. When the second positioning member 2 is in the first position, the convex block 222 is clamped to the contact wall 5 of the profile groove, the antenna 221 moves towards the operation gap 3, the hook end 22a is squeezed away from the limiting wall 12, and the pawls 21a of the elastic connection section 21 are restricted by the wall surface of the limiting cavity 11 to achieve contraction; when the second positioning member 2 is in the second position, the convex block 222 is separated from the contact wall 5 of the profile groove, the pawls of the elastic connection section 21 recover their elasticity and expand in the limiting cavity 11 until the hook end 22a is buckled on the limiting wall 12 to achieve a position change of the second positioning member 2 relative to the first positioning member 1; preferably, by Figure 1 and Figure 4As shown, the bump 222 has an inclined surface 2221. The inclined surface 2221 protrudes outward toward one end of the antenna 221, and the outward protruding part is inclined downward. When installing this connecting device, one end of the connecting seat 101 is fixed on one of the contact walls 5 of the profile groove, and then the connecting device is pressed. The inclined surface 2221 gradually abuts against the other contact wall 5 of the profile groove, guiding the antenna 221 to move toward the operation gap 3. The outward protruding part of the bump 222 moves along with the antenna 221 toward the operation gap 3, guiding the entire inclined surface 2221 to move better along the direction of the contact wall 5 of the profile groove, so that the bump 222 is better clamped on the contact wall 5 without jamming, with high installation efficiency and stable structure.

[0023] Among them, as shown by Figure 2 , Figure 4 , Figure 5 and Figure 6 shown, the first positioning member 1 also has a clamping wall 13. The clamping wall 13 is located at one end of the first positioning member 1 away from the limiting cavity 11 and is used to clamp on the other contact wall 5 of the profile groove. The clamping wall 13 has an L-shaped structure, which is convenient for clamping on 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 elaborated here. When installing this connecting device, the clamping wall 13 of the first positioning member 1 is clamped on 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, and the other end of the connecting device leans 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 bump 222 gradually enters the inner cavity of the profile groove, and the inclined surface 2221 of the bump 222 contacts the other contact wall 5 of the profile groove, adjusting the antenna 221 to move toward the operation gap 3 until the inclined surface 2221 can contact this contact wall 5. At this time, the external force pressing on the connecting device is removed, the antenna 221 moves away from the operation gap 3, and the bump 222 pops out and is clamped on the contact wall 5 of the profile groove. Without considering the preset notch for installing the connecting device, the connecting device can be matched and installed in the profile groove.

[0024] For the stable installation of the structure, as shown by Figures 2 to 4As shown, the connecting device further includes a locking member 103. The connecting seat 101 is provided with a locking hole 104 that penetrates up and down, and the locking member 103 is inserted and fixed in the locking hole 104. In this embodiment, the locking member 103 is a locking pin. One end of the locking pin passes through the locking hole 104, and the other end of the lock is 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. After the connecting device is connected to the transmission rod of the door and window, the closing or opening state of the door and window is adjusted through this locking pin. When the door and window are closed or opened, the transmission rod moves, driving the connecting device to move. If it is found that it is difficult to push the door and window, the locking can be loosened or tightened so that the connecting device can move along with the transmission rod, which is convenient for adjustment, ensuring that the installed door and window closes or opens smoothly, and giving users a good product experience.

[0025] Further, the assembly relationship between the transmission rod and the connecting device is composed of Figure 3 and Figure 7 As shown, the connecting device also has a connecting block 102 and a fastener 106. The connecting block 102 is fixedly installed at one end of the connecting seat 101 away from the locking member 103. The connecting block 102 is provided with a fastening hole 107 that penetrates up and down. The left and right sides of the connecting block 102 are bent downward to form an inner cavity 108 for adapting to the transmission rod 4. One side of the connecting block 102 facing the inner cavity 108 is provided with an anti-fooling convex point 105, and the anti-fooling convex point 105 is adapted to the anti-fooling groove 41 of the transmission rod 4. In this embodiment, the fastener 106 is a fastening screw, and 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. Among them, installing the transmission rod 4 of the door and window is a conventional technical means and will not be elaborated in detail here. In this embodiment, the transmission rod 4 is inserted into the inner cavity 108 of the connecting block 102, and one side of the connecting block 102 facing the inner cavity 108 is provided with an anti-fooling convex point 105, which can be adapted to the anti-fooling groove 41 of the transmission rod 4 to guide the transmission rod 4 to move along the length direction of the profile slot and prevent the transmission rod 4 from being misinstalled in the profile slot.

[0026] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
