Technical Field

[0001] This invention relates to the field of door and window hinges, and more specifically, to a quick-release hinge kit. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. As a commonly used door and window hardware accessory, hinges are generally used in the door and window industry to fix the sash frame to the window frame profile, and the opening and closing of the sash frame is achieved through the linkage mechanism of the hinge.

[0003] In the existing technology, the installation of the sash frame requires the cooperation of upper and lower hinges. The upper hinge has a mounting base for fixing to the window frame and a fixing hinge for fixing to the top of the window sash. When installing the upper hinge, the fixing hinge is placed on the window sash, and a certain space must be reserved between the mounting base and the edge of the window sash. The length of this space is determined by measurement. At this time, one hand is needed to hold the position of the hinge to ensure that it does not shift back and forth. The position of the fixing hinge also needs to be fixed with bolts, which is very inconvenient for installation. Summary of the Invention

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] The embodiments of the present invention will now be described in further detail with reference to the accompanying drawings, as follows:

[0026] A quick-release hinge kit includes a window frame fixing part 3 connected to a window frame 1 and a sash frame fixing part 4 connected to a sash frame 2. A rotating arm 5 is rotatably connected to the upper surface of the window frame fixing part 3, and a long connecting rod 6 is hinged to one end. The rotating arm 5 is rotatably connected to one end of the sash frame fixing part 4, and the long connecting rod 6 is rotatably connected to the middle of the sash frame fixing part 4, forming a linkage mechanism that opens or closes relative to the window frame fixing part 3. A barb 7 is provided extending from one end of the rotating arm 5 in the sash frame fixing part 4. A lock body 9 is provided above the barb 7 in the sash frame fixing part 4. The lock body 9 cooperates with the barb 7. An elastic member 8 is provided at the other end of the sash frame fixing part 4 to abut against it.

[0027] During installation, the present invention first uses the fan frame fixing part 4 to measure the depth to which the fan frame fixing part 4 is inserted into one end corner of the fan frame 2. Then, the elastic element 8 is inserted into the fan frame 2 at the corresponding depth, so that the fan frame fixing part 4 contacts the elastic element 8 after insertion and presses the spring 15 of the elastic element 8. Then, the fan frame 2 is tightened by rotating the flat end set screw 18, so that the hook of the elastic element 8 is engaged with the fan frame 2, thereby fixing the elastic element 8. The lock body 9 is inserted into the other end corner of the fan frame 2, and the barb 7 protrudes. In the first position, the window frame fixing part 3 is installed on the window frame 1 by means of the locking piece 25, thus fixing the hinge. When installing the sash frame 2, simply insert the sash frame 2 into the sash frame fixing part 4 of the hinge, so that the locking hook 11 and the barb 7 are engaged with each other, and the installation of the sash frame 2 is completed. The installation steps of the upper hinge and the lower hinge of the sash frame 2 are the same, and will not be repeated here. When disassembling the sash frame 2, simply press the pressing part 26 to push the locking hook 11 away from the barb 7, and the sash frame 2 can be disassembled.

[0028] The lock body 9 includes a lock seat 10, a pressing member 26 mounted on the upper end of the lock seat 10, and a lock hook 11 movably mounted on the bottom of the lock seat 10. A first push rod 12, penetrating the lock seat 10, is connected to the bottom of the pressing member 26, and the first push rod 12 contacts one end of the lock hook 11. The middle part of the lock hook 11 is rotatably connected to the lock seat 10 via a pivot 13, forming a lever structure. When the first push rod 12 pushes one end of the lock hook 11, the other end of the lock hook 11 separates from the barb 7. A second push rod 14 is mounted on the lock seat 10 at the other end of the lock hook 11. One end of the second push rod 14 contacts the lock hook 11, and a spring 15 is provided between the other end and the lock seat 10. The lock seat 10 is hollow above the second push rod 14 and is connected via... The set screw 17 is tightened to the upper end of the second push rod 14, so that the second push rod 14 and the spring 15 are installed in sequence to achieve the limit. The second push rod 14 has a stepped structure, which can prevent the second push rod 14 from falling off the lock seat 10. The spring 15 applies a pushing force to the second push rod 14, so that the end of the second push rod 14 protruding from the lock seat 10 abuts against the lock hook 11, so that the lock hook 11 can be moved back and forth by the first push rod 12 and the second push rod 14. The middle part of the pressing member 26 has a waist-shaped groove 16, and the screw 17 passes through the waist-shaped groove 16 to connect the pressing member 26 to the lock seat 10. By passing the screw 17 through the waist-shaped groove 16, the pressing member 26 can be fixed after the fan frame 2 is installed, so as to prevent the fan frame 2 from being disengaged from the hinge by accidentally touching the pressing member 26.

[0029] One side of the lock body 9 is movably inserted into the fan frame 2, and the lock body 9 is fixed to the fan frame 2 by passing through the flat-end set screw 18. The elastic element 8 is movably inserted into the fan frame 2 and is fixed to the fan frame 2 by the flat-end set screw 18.

[0030] A pad 19 is provided between the fan frame fixing part 4 and the long connecting rod 6, and between the fan frame fixing part 4 and the rotating arm 5. The fan frame fixing part 4 and the rotating arm 5 are connected by a pin 20. The pad 19 can reduce the friction between the fan frame fixing part 4 and the long connecting rod 6 and between the fan frame fixing part 4 and the rotating arm 5 during rotation, effectively improving the service life of the hinge. In addition to fixing the fan frame fixing part 4 and the rotating arm 5, the pin 20 can also achieve the positioning effect by cooperating with the lock body 9 at the top.

[0031] One end of the window frame fixing part 3 is connected to a fastener 21 with an L-shaped structure. The fastener 21 is located at one end of the window frame fixing part 3 and is connected by a positioning pin 22. The other end is provided with a connecting hole 23. The connecting hole 23 is used to connect one end of the fastener 21 to the window frame 1, and the other end of the fastener 21 is connected to the window frame fixing part 3. This can reduce the force exerted by the hinge on one side of the window frame 1, making the hinge installation more stable. An offset screw 24 is connected between the window frame fixing part 3 and the fastener 21. Locking pieces 25 are rotatably connected to the bottom of both ends of the window frame fixing part 3, and the window frame fixing part 3 is connected to the window frame 1 through the two locking pieces 25.

[0032] The present invention adds a barb 7 to the hinge and installs a lock body 9 on the sash frame 2 above the barb 7. An elastic element 8 is installed on the end of the sash frame 2 opposite to the barb 7. The cooperation between the barb 7 and the lock body 9 enables the sash frame 2 to be quickly installed on the window frame 1. The elastic force of the elastic element 8 on the rotating arm 5 can effectively prevent the barb 7 from falling off, so as to achieve a stable connection between the hinge and the sash frame 2 and facilitate installation and disassembly.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
