Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, and in particular to a quick-installation and quick-disassembly connection mechanism between a hinge and a door / window sash. Background Technology

[0002] In the field of door and window installation, the convenience and aesthetics of hinge connection structures have always been key industry concerns. Traditional door and window connection mechanisms mostly use screw fixing, locking the hinge components to the window frame and sash with threads. While this structure provides a stable connection, it has significant drawbacks: when users need to disassemble, clean, or maintain the screen, tools must be used to remove the screws, making the process cumbersome and time-consuming. Frequent disassembly can also lead to stripped screws or loose mounting holes, affecting structural reliability. Furthermore, exposed screw heads are prone to accumulating dust and rust, compromising the overall appearance of the product.

[0003] To improve assembly and disassembly efficiency, quick-assembly and quick-disassembly connection structures have gradually emerged in the market, but their design still faces the following technical bottlenecks:

[0004] 1. Bushing-fixed quick-install structure: This structure uses a pull-type unlocking mechanism for quick disassembly, but the fixed end still needs to be pre-fixed to the window frame / window sash with screws or screws. Although it simplifies disassembly, pre-drilling holes and tightening screws are still required in the main structure during installation, which does not significantly reduce the overall process complexity, and the problem of exposed screws at the fixed end remains unresolved.

[0005] 2. Screw-unlocking quick-release structure: This type of structure relies on loosening the screws to achieve separation. While it eliminates the traditional multi-screw fixing step, tools are still needed to adjust the screw tightness during disassembly, making it less convenient to operate. Furthermore, the unlocking screw is directly exposed, affecting aesthetics and posing a risk of accidental loosening.

[0006] This utility model is based on the above-mentioned circumstances. Utility Model Content

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] like Figures 1 to 8 The invention relates to a quick-installation and quick-disassembly connection mechanism for a hinge and a door / window sash. The mechanism includes a first connecting seat 1 for connecting the door / window sash and a second connecting seat 2 for connecting the hinge. A connecting device is provided between the first connecting seat 1 and the second connecting seat 2 to connect the two and to disengage the first connecting seat 1 and the second connecting seat 2 when the external force exceeds a preset value. A plug-in 3 is connected to the second connecting seat 2, and a plug-in slot 10 is provided on the first connecting seat 1 for the plug-in 3 to be inserted.

[0035] In some embodiments, the connecting device includes a slot 41 on the connector 3 and an elastic insert 42 on the first connecting seat 1 that extends into the slot 41 after the connector 3 is inserted into the slot 10 to form a locking mechanism. The elastic insert 42 may be an arc-shaped locking block or ring on the first connecting seat 1, relying on its own deformation to engage or disengage, or it may be a spring-loaded pin structure on the first connecting seat 1.

[0036] In some embodiments, the connecting device includes a slot 41 on the wall of the insertion slot 10 and an elastic insert 42 on the insertion member 3 that extends into the slot 41 after the insertion member 3 is inserted into the insertion slot 10 to form a locking mechanism. The elastic insert 42 may be an arc-shaped locking block or ring on the outer wall of the insertion member 3 that engages or disengages based on its own deformation, or it may be a spring-loaded pin structure on the outer wall of the insertion member 3.

[0037] This product adopts a mating design of connector 3 and connector slot 10. Through the automatic locking mechanism of built-in elastic plug 42 and slot 41, the connection can be completed without tools during installation. When disassembling, only vertical force is needed to push it out, eliminating the traditional screw fixing steps. It is especially suitable for screen window scenarios that need to be frequently removed and cleaned. Its connection structure is completely hidden in the mating gap, with no exposed fasteners. The appearance is simple and flat, which meets the aesthetic requirements of modern door and window concealed design.

[0038] In one embodiment, a pushing structure 6 is provided between the groove wall of the slot 41 and the elastic plug 42 to help the elastic plug 42 exit the slot 41 when the external force pushing out the first connecting seat 1 exceeds a preset value. The pushing structure 6 includes a first inclined surface structure or a first arc-shaped surface structure. The pushing structure 6 may be provided only on the groove wall of the slot 41, or only on the elastic plug 42, or both the groove wall of the slot 41 and the elastic plug 42 may be provided with mutually cooperating pushing structures 6.

[0039] In one embodiment, a slot 41 is provided on the side wall of the connector 3, the elastic plug 42 is connected to the first connecting seat 1, and the end of the connector 3 is provided with a second inclined surface structure or a second arc-shaped surface structure 31 for pushing the elastic plug 42 when it is inserted into the connector slot 10. It is most preferred that the end of the connector 3 is provided as a spherical surface or a conical platform.

[0040] In some embodiments, the elastic insert 42 includes a top bead 421 and an elastic element 422 disposed between the top bead 421 and the first connecting seat 1. One side of the first connecting seat 1 has a receiving groove 11, within which a plug-in block 7 is disposed. A plug-in cavity 101 is formed between the groove wall of the receiving groove 11 and the plug-in block 7. The other side of the first connecting seat 1 has a plug-in interface 102 communicating with the plug-in cavity 101. The plug-in interface 102 and the plug-in cavity 101 form a plug-in groove 10. The plug-in block 7 includes a back 71 and a side arm 72 connected to the back 71 and extending into the plug-in cavity 101. The side arm 72 has a mounting groove 721 for placing the top bead 421 and the elastic element 422, and an inner hole 722 for the top bead 421 to extend out and insert into the slot 41. The opening of the plug-in groove 10 can be located on the side of the first connecting seat 1 near the mounting surface, thereby forming a shield and improving aesthetics. Meanwhile, the separate processing of the plug-in block 7 makes the mechanism easier to process and disassemble.

[0041] Furthermore, the wall of the through hole 722 is provided with a protrusion 723 to prevent the top bead 421 from dislodging from the through hole 722. One end of the elastic element 422 abuts against the top bead 421, and the other end abuts against the groove wall of the receiving groove 11. The elastic element 422 may be a spring or other elastic element.

[0042] Furthermore, two side arms 72 are symmetrically arranged on both sides of the back 71, or the back 71 is ring-shaped with multiple side arms 72 evenly arranged along the circumference, and the connector 3 is inserted into the inside of the side arms 72, thereby improving the stability of the connection.

[0043] The door / window sash includes an outer frame 81 and a movable sash 83 connected to the outer frame 81 via hinges 82. The first connecting seat 1 has locking structures 12 on both sides for engaging with the movable sash 83. The second connecting seat 2 has a connecting mechanism 20 that allows it to be fixedly connected to the hinges 82. The locking structure 12 can be a slot or a block, or other easily detachable structure. The connecting mechanism 20 can be a mounting hole, connected via a hinge pin or other connecting structure.

[0044] In some embodiments, the second connecting seat 2 includes a connecting plate 22 for connecting the plug-in member 3. A limiting plate 21 for restricting the swing of the second connecting seat 2 is held between the connecting plate 22 and the hinge. A locking groove 24 for engaging with the movable fan 83 is provided between the connecting plate 22 and the hinge. The limiting plate 21 has a locking section 211 that is narrower at the front and wider at the back. The two side walls of the locking section 211 form the bottom of the locking groove 24, thereby gradually locking the movable fan 83 when it is plugged in. The lower part of the connecting plate 22 has a protrusion 221 that extends into the locking groove 24 to further lock the movable fan 83. The limiting plate 21 can be connected to the hinge 82 via other connecting structures such as a hinge seat or an elastic buckle. The connecting plate 22 can be connected to the limiting plate 21 by other connecting structures such as hinge seats or elastic buckles. The connecting plate 22 or the limiting plate 21 is provided with positioning holes 200. When the connecting plate 22 is provided with positioning holes 200, the limiting plate 21 is provided with positioning blocks 23 that can be inserted into the positioning holes 200. When the limiting plate 21 is provided with positioning holes 200, the connecting plate 22 is provided with positioning blocks 23 that can be inserted into the positioning holes 200, thereby restricting the hinge 82 from swaying left and right or up and down.

[0045] Furthermore, the connecting plate 22 is a metal part and the support plate 21 is a plastic part. Compared with the noise caused by hard friction between metal parts, the fit between the metal parts and the plastic parts can further reduce the noise caused by friction between the support plate 21 and the hinge 82.

[0046] In one embodiment, the connector 3 is threaded or riveted to the second connector 2. Of course, the connector 3 can also be connected to the second connector 2 by other connection methods such as glue or welding, and the connector 3 and the second connector 2 can also be an integral structure.
