Description
Technical Field
[0001] This utility model relates to the field of door and window accessories, and in particular to a quick-installation and quick-disassembly connection structure between a hinge and a door or window sash. Background Technology
[0002] In the field of door and window hinge connections, traditional technology commonly uses screws to fasten components. While this method provides a stable connection, it has significant drawbacks in practical applications. Especially for applications like screens that require frequent cleaning, users must manually remove each screw to detach the screen, a cumbersome and time-consuming process. Furthermore, repeated disassembly and reassembly can cause wear on the screw holes, affecting the long-term reliability of the connection. As users increasingly demand convenience, traditional screw fastening methods are no longer sufficient to meet the needs of modern home products for quick maintenance.
[0003] To address the aforementioned issues, existing technologies have proposed two types of quick-assembly and quick-disassembly structural improvement schemes. The first type employs a bushing fixing mechanism, which achieves rapid separation by setting a sliding unlocking component on the connecting seat. However, the core drawback of this structure is that the fixing component still relies on screws or threaded fasteners for initial installation, resulting in the overall assembly process still including the complex steps of traditional screw fixing, failing to completely simplify the installation process. The second type of improvement scheme uses a screw unlocking mechanism, that is, separating the connecting components by loosening the screws. However, this method still essentially relies on tool operation, and the screw tightening angle needs to be precisely controlled during the unlocking process, resulting in high operational complexity and making it difficult to achieve true "one-click" assembly and disassembly. A more prominent common problem is that existing quick-assembly structures generally use exposed mechanical components, such as protruding locking pins, visible screw heads, or unlocking levers, which not only disrupts the overall appearance of the product but also poses safety hazards such as components hooking foreign objects or accidental unlocking.
[0004] This utility model is based on the above-mentioned circumstances. Utility Model Content
[0005] This invention overcomes the shortcomings of the prior art and provides a quick-install and quick-release connection structure for hinges and door / window sashes that is easy to install and remove and does not require screws for fastening.
[0006] This utility model is achieved through the following technical solution:
[0007] A quick-install and quick-release connection structure for a hinge and a door / window sash includes a first connecting seat for connecting the door / window sash and a second connecting seat for connecting the hinge. The second connecting seat is provided with a limiting part, and a pressing member is movably connected to the first connecting seat. The pressing member includes a latching part that can lock with the limiting part to connect the second connecting seat and the first connecting seat. The latching part is provided with a pressing part that can drive the latching part to disengage from the limiting part when pressed. The pressing member is elastically connected to the first connecting seat so that the pressing member can be reset and the latching part can be locked with the limiting part.
[0008] As described above, in a quick-installation and quick-release connection structure between a hinge and a door / window sash, the pressing component is slidably connected to the first connecting seat.
[0009] As described above, a quick-installation and quick-disassembly connection structure for a hinge and a door / window sash is provided on the first connecting seat, which is provided with a guide structure to guide the sliding of the pressing member. The guide structure includes a guide groove or a guide block provided on the first connecting seat. The pressing member is provided with a slider that cooperates with the guide groove or a sliding groove that cooperates with the guide block.
[0010] As described above, in a quick-installation and quick-release connection structure between a hinge and a door / window sash, the middle part of the pressing member is rotatably connected to the first connecting seat, the locking part is the tail of the pressing member, and the pressing part is the head of the pressing member.
[0011] As described above, a quick-install and quick-release connection structure for a hinge and a door / window sash is provided in the first connecting seat, which has a receiving cavity to provide space for the movement of the pressing part, and a socket for the limiting part to be inserted into the receiving cavity is provided on one side of the first connecting seat.
[0012] As described above, in a quick-installation and quick-disassembly connection structure between a hinge and a door / window sash, the first connecting seat is provided with a first limiting block that extends into the socket, and the first limiting block circumferentially positions the limiting part within the socket.
[0013] As described above, in a quick-installation and quick-disassembly connection structure between a hinge and a door / window sash, the receiving cavity is further provided with a second limiting block that can guide and limit the insertion of the limiting part.
[0014] As described above, in a quick-installation and quick-release connection structure between a hinge and a door / window sash, the latch is located within a receiving cavity, and one side of the first connecting seat is provided with a through hole or clearance groove for the pressing part to pass through.
[0015] As described above, in a quick-installation and quick-disassembly connection structure between a hinge and a door / window sash, an elastic reset member is provided between the pressing member and the first connecting seat, which can reset the pressing member and thus lock the latching part and the limiting part together.
[0016] As described above, a quick-install and quick-release connection structure for a hinge and a door / window sash includes a second connecting seat comprising a connecting plate for connecting a limiting part. A support plate for limiting the swing of the second connecting seat is clamped between the connecting plate and the hinge. A snap-fit groove for engaging with the movable sash is provided between the connecting plate and the hinge. The support plate is provided with a snap-fit section that is narrower at the front and wider at the back. The side walls of the snap-fit section are the bottom of the snap-fit groove. The lower part of the connecting plate is provided with a protrusion that extends into the snap-fit groove to further engage the movable sash.
[0017] Compared with the prior art, the present invention has the following advantages:
[0018] This invention utilizes a flexible linkage design between the pressing component and the first connecting seat. Users only need to press the pressing component to trigger the locking part to disengage from the limiting part, eliminating the need for a screwdriver or other tools. Compared to traditional screw fixing and the unlocking methods in existing quick-release structures that still require unscrewing screws, operational efficiency is greatly improved.
[0019] The first and second connecting seats are directly engaged with the limiting part via a locking buckle, eliminating the need for traditional screw fixing or the pre-tightening step of the fixing seat in existing quick-installation structures. During installation, only alignment and pressing are required to lock the seat, without the need for screws for fixing, and there are no exposed screws or pins, thus making the product more aesthetically pleasing.
[0020] The pressing component is elastically connected to the first connecting seat. After pressing, it automatically pushes the locking part to reset and lock, eliminating the error of manual reset. Its elastic preload can adapt to the slight deformation of the limiting part, and it still maintains stable locking under the conditions of door and window sash vibration or temperature expansion. Compared with rigid locking structures without elastic compensation, the connection of this case is more reliable. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings:
[0032] like Figures 1 to 9 The diagram illustrates a quick-install and quick-release connection structure between a hinge and a door / window sash, comprising a first connecting seat 1 for connecting the door / window sash and a second connecting seat 2 for connecting the hinge. The second connecting seat 2 is provided with a limiting part 3. A pressing member 4 is movably connected to the first connecting seat 1. The pressing member 4 includes a latching part 41 that can lock with the limiting part 3 to connect the second connecting seat 2 and the first connecting seat 1. The latching part 41 is provided with a pressing part 42 that can drive the latch to disengage from the limiting part 3 when pressed. The pressing member 4 is elastically connected to the first connecting seat 1, thereby allowing the pressing member 4 to reset and thus locking the latching part 41 with the limiting part 3.
[0033] This utility model adopts an elastic linkage design between the pressing part 4 and the first connecting seat 1. The user can quickly unlock the locking part 41 by pressing it off from the limiting part 3. Compared with the traditional screw fixing and quick-installation structure that requires screw tightening, the operation efficiency is significantly improved. The first connecting seat 1 and the second connecting seat 2 are directly snapped together by the locking part 41, eliminating the pre-tightening step and eliminating exposed screws. During installation, the locking is completed by pressing the alignment part, which is both convenient and aesthetically pleasing. The pressing part is elastically connected to the first connecting seat. After pressing, the locking part 41 is automatically reset and a pre-tightening force is continuously provided. It can adapt to the slight deformation of the limiting part 3 and maintain stable locking under vibration or temperature change conditions, which is more reliable than the traditional rigid locking structure.
[0034] The door / window sash includes an outer frame 61 and a movable sash 63 connected to the outer frame 61 via a hinge 62. In some embodiments, the first connecting seat 1 has locking grooves 16 on both sides for engaging with the outer frame 61 or the movable sash 63, thus eliminating the need for screws to connect the first connecting seat 1 to the outer frame 61 or the movable sash 63, making the connection very convenient and quick. The second connecting seat 2 is provided with a connecting mechanism 20 that allows it to be fixedly connected to the hinge 62. The connecting mechanism 20 can be a mounting hole, connected via a hinge pin or other connecting structure.
[0035] In some embodiments, the pressing element 4 is made of an elastic material and can be reset by its own elasticity.
[0036] In some embodiments, an elastic reset member 5 is further provided between the pressing member 4 and the first connecting seat 1, which can reset the pressing member 4 and thus lock the locking part 41 with the limiting part 3. The elastic reset member 5 may be a reset spring or other elastic structure.
[0037] In some embodiments, the limiting part 3 may be a connecting ear, hook, slot or pin, or other structure that can be fastened to the locking member 41. The locking member 41 may also be a connecting ear, hook, slot or pin.
[0038] In some embodiments, the first connecting seat 1 is provided with a receiving cavity 10 that provides space for the pressing member 4 to move. The limiting part 3 may be provided outside the first connecting seat 1 or inside the receiving cavity 10.
[0039] In some embodiments, the first connecting seat 1 includes a housing 14 and a baffle 15 connected to the housing 14. The receiving cavity 10 is formed by the housing 14 and the baffle 15. The pressing part 42 is provided with a first positioning post 421. The baffle 15 is provided with a second positioning post 151 opposite to the first positioning post 421. One end of the elastic reset member 5 is sleeved on the first positioning post 421, and the other end is sleeved on the second positioning post 151.
[0040] Furthermore, the outer casing 14 is provided with at least two insertion posts 141, and the baffle 15 is provided with insertion holes 152 at the corresponding positions of the insertion posts 141. Of course, the baffle 15 can be connected to the outer casing 14 by interference fit between the insertion posts 141 and the insertion holes 152. The baffle 15 can also be connected to the outer casing 14 by connection structures such as snap-fit, welding, hot melt or glue.
[0041] like Figures 1-4 As shown, in some embodiments, the pressing member 4 is slidably connected to the first connecting seat 1, and the side wall of the receiving cavity 10 is provided with a guide structure 11 to guide the sliding of the pressing member 4. The guide structure 11 ensures the locking accuracy of the locking part 41 by constraining the sliding trajectory of the pressing member 4. Specifically, the guide structure 11 includes a guide groove or guide block provided on the side wall of the receiving cavity 10, and the pressing member 4 is provided with a slider 43 that cooperates with the guide groove or a sliding groove that cooperates with the guide block.
[0042] Furthermore, the locking part 41 is located in the receiving cavity 10. The first connecting seat 1 has a through hole 140 or a relief groove on one side for the pressing part 42 to pass through, which makes it easier to operate. The baffle 15 has an insertion port 150 for the locking part 41 to enter, which makes the structure more compact and reduces the size of the product.
[0043] like Figures 5-6 As shown, in some embodiments, the middle part of the pressing member 4 is rotatably connected to the first connecting seat 1 via a pivot, thereby forming a seesaw structure. The locking part 41 is the tail of the pressing member 4, and the pressing part 42 is the head of the pressing member 4. When the pressing part 42 is pressed, the locking part 41 can be lifted to unlock it. When the pressing part 42 is released, the pressing part 42 is reset by its own elasticity or by the elastic reset member 5, thereby driving the locking part 41 to lock with the limiting part 3. Further, the outer shell 14 is provided with a clearance hole 142 to avoid the pressing member 4.
[0044] In some embodiments, the locking part 41 and the pressing part 42 are an integral structure, eliminating the weak areas of welding points or screw connections in traditional separate structures. This reduces the risk of breakage and improves fatigue resistance. It also improves the accuracy of transmission and movement.
[0045] In some embodiments, the first connecting seat 1 has an insertion port 12 on one side for the limiting part 3 to be inserted into the receiving cavity 10. The insertion of the limiting part 3 into the receiving cavity 10 makes the structure of the product more compact, and at the same time, it can also cover the limiting part 3 and the locking part 41, making the product more aesthetically pleasing.
[0046] In some embodiments, the first connecting seat 1 is provided with a first limiting block 12 that extends into the socket 12. The first limiting block 12 positions the limiting part 3 circumferentially within the socket 12. The receiving cavity 10 is also provided with a second limiting block 131 that can guide and limit the insertion of the limiting part 3. The cooperation of the first limiting block 13 and the second limiting block 131 restricts the left-right and front-back swaying of the limiting part 3, thereby reducing the shaking and abnormal noise of the movable fan 63 when it is opened and closed.
[0047] like Figures 8-9As shown, in some embodiments, the second connecting seat 2 includes a connecting plate 22 connecting the limiting part 3. A support plate 21 for limiting 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 63 is provided between the connecting plate 22 and the hinge. The support 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 63 when it is inserted. 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 63. The support plate 21 can be connected to the hinge 62 via other connecting structures such as a hinge seat or an elastic buckle. The connecting plate 22 can be connected to the support plate 21 by other connecting structures such as hinge seats or elastic buckles. The connecting plate 22 or the support plate 21 is provided with positioning holes 200. When the connecting plate 22 is provided with positioning holes 200, the support plate 21 is provided with positioning blocks 23 that can be inserted into the positioning holes 200. When the support 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 62 from swaying left and right or up and down.
[0048] 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 62.
