[0033] The present invention is further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0034] See also Figure 1-Figure 10 The quick disassembly and assembly structure of concealed hinges for doors and windows of the present invention comprises a hinge seat 2, a hinge body 1 arranged on the hinge seat 2, and a disassembly and assembly structure for realizing quick disassembly and assembly of the hinge seat 2 and the hinge body, wherein the disassembly and assembly structure comprises a clamping strip 5, a front buckle 7 arranged on the front side of the clamping strip 5, and a tail buckle 9 arranged on the rear side of the clamping strip 5, wherein the clamping strip 5 is installed on the hinge body 1; the front buckle 7 is rotatably connected to the front side of the clamping strip 5; the tail buckle 9 is rotatably connected to the rear side of the clamping strip 5; in this embodiment, the front buckle 7 is rotatably connected to the clamping strip 5 through a front buckle pin 6; the tail buckle 9 is rotatably connected to the clamping strip 5 through a tail buckle pin 8; a front clamping position is provided on the front side of the hinge seat 2 at a position corresponding to the front buckle 7; a rear clamping position is provided on the rear side of the hinge seat 2 at a position corresponding to the tail buckle 9; when the hinge body 1 is installed on the hinge seat 2, the front buckle 7 and the tail buckle 9 are respectively fastened to the clamping grooves on the front and rear sides of the hinge seat 2.

[0035] See also Figure 1-Figure 10The front buckle 7 is a spring-type front buckle, which includes a front buckle body 701, a front clip 702 and a spring piece 703 arranged on the front buckle body 701, wherein the bottom of the front clip 702 is an arc-shaped portion, and a slot is arranged at the upper end of the arc-shaped portion; the spring piece 703 is a U-shaped structure, one end of the spring piece 703 is installed on the front buckle body 701, and the other end is connected to the elastic limiting portion 704; a front buckle protrusion 12 is arranged at the front end of the clamping strip 5; when the hinge body 1 is installed on the hinge seat 2, the front buckle protrusion 12 is located between the elastic limiting portion 704 and the front buckle 702. With the above arrangement, when the front buckle 7 is installed on the clamping strip 5, it is necessary to ensure that the front buckle protrusion 12 on the clamping strip 5 is located between the elastic limiting portion 704 and the front buckle 702; in this way, when the hinge body 1 is installed on the hinge seat 2, the arc-shaped portion at the bottom of the front buckle 702 in the front buckle 7 will contact the front clamping position on the hinge seat 2. In the process of mutual squeezing, the front clamping position will prompt the front buckle 7 to rotate clockwise. At this time, the front buckle protrusion 12 will contact the elastic limiting portion 704. Under the limitation of the position part 704, the spring piece 703 of the U-shaped structure will undergo elastic deformation, that is, the front buckle 702 overcomes the elastic force of the spring piece 703 and rotates clockwise. When the front clamping position passes over the arc-shaped part at the bottom of the front buckle 702 and enters the slot above it, the front buckle 702 will rotate counterclockwise under the elastic reset of the spring piece 703, so that the slot on the front buckle 702 is inserted into the front clamping position of the hinge seat 2, thereby realizing the quick installation of the front buckle 7.

[0036] In this embodiment, the front buckle body 701, the front buckle 702, the spring piece 703 and the elastic limiting portion 704 are two groups, and the two groups are symmetrically arranged and form an integrated structure.

[0037] See also Figure 1-Figure 10 The tail buckle 9 includes a tail buckle body 901, a tail clip 902 arranged on the tail buckle body 901, and a rotation driving part 903; wherein, the bottom of the tail clip 902 is also an arc-shaped part, and a card slot is arranged at the upper end of the arc-shaped part; the rotation driving part 903 extends outward at an angle; in order to realize the elastic reset of the tail buckle 9, a torsion spring 10 is arranged on the tail buckle needle 8, one end of the torsion spring 10 acts on the clamping strip 5, and the other end acts on the tail buckle 9, and the elastic force of the torsion spring 10 prompts the tail buckle 9 to rotate downward.

[0038] Through the above arrangement, when the hinge body 1 is installed on the hinge seat 2, the arc-shaped portion at the bottom of the tail buckle 902 in the tail buckle 9 will contact the rear clamping position on the hinge seat 2. In the process of mutual squeezing, the rear clamping position will prompt the tail buckle 9 to overcome the elastic force of the torsion spring 10 and rotate counterclockwise. When the rear clamping position passes over the arc-shaped portion at the bottom of the tail buckle 902 and enters the clamping groove above it, the tail buckle 902 will rotate clockwise under the elastic reset of the spring piece 703, so that the clamping groove on the tail buckle 902 is clamped into the rear clamping position of the hinge seat 2, thereby realizing the rapid installation of the tail buckle 9.

[0039] See also Figure 1-Figure 10 Two positioning holes 201 are symmetrically arranged on the hinge seat 2; a positioning portion 11 cooperating with the positioning hole 201 is arranged on the clamping strip 5 at a position corresponding to the positioning hole 201; by setting the positioning hole 201 and the positioning portion 11, it is convenient for the installer to determine the relative position between the hinge body 1 and the hinge seat 2 during installation, which helps to achieve rapid installation between the hinge body 1 and the hinge seat 2.

[0040] See also Figure 1-Figure 10 The hinge seat 2 is provided with limit blocks 202, and the limit blocks 202 are symmetrically arranged on both sides of the hinge seat 2; when the hinge body 1 is installed on the hinge seat 2; the outer side surfaces of the two groups of limit blocks 202 are in contact with the inner side surfaces on both sides of the clamping strip 5, so as to prevent the hinge seat 2 and the hinge body 1 from being offset to the left and right.

[0041] See also Figure 1-Figure 10 The clamping strip 5 is a hollow structure, which is helpful to reduce the weight of the clamping strip 5 and reduce its manufacturing cost.

[0042] See also Figure 1-Figure 10 A limit adjustment wire 3 is provided on the hinge body 1, and a U-shaped groove 501 cooperating with the limit adjustment wire 3 is provided on the clamping strip 5; in addition, an eccentric nail 4 is also provided on the hinge body 1, and an adjustment groove 502 is provided on the clamping strip 5 at a position corresponding to the eccentric nail 4.

[0043] In this embodiment, the structures and functions of the above-mentioned limit adjustment wire 3 and eccentric nail 4 can be implemented with reference to the relevant structures in the existing hinges, and no further description will be given again.
