[0029] The present utility model will be further described in detail below in conjunction with the embodiments and the drawings, but the embodiments of the present utility model are not limited thereto.

[0030] Refer to Figures 1 - 11, the quick disassembly and assembly structure of the concealed hinge for doors and windows of the present utility model includes a hinge seat 2, a hinge body 1 arranged on the hinge seat 2, and a disassembly and assembly structure for realizing the quick disassembly and assembly of the hinge seat 2 and the hinge body. Among them, the disassembly and assembly structure includes a strip 5, a front buckle 7 arranged on the front side of the strip 5, and a tail buckle 9 arranged on the rear side of the strip 5. Among them, the strip 5 is installed on the hinge body 1; the front buckle 7 is rotatably connected to the front side of the strip 5; the tail buckle 9 is rotatably connected to the rear side of the strip 5; in this embodiment, the front buckle 7 is rotatably connected to the strip 5 through a front buckle pin 6; the tail buckle 9 is rotatably connected to the strip 5 through a tail buckle pin 8; a front clamping position is arranged at the corresponding position of the front side of the hinge seat 2 with respect to the front buckle 7; a rear clamping position is arranged at the corresponding position of the rear side of the hinge seat 2 with respect 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.

[0031] See Figures 1 - 11 , the front buckle 7 is a spring plate type front buckle. The spring plate type front buckle includes a front buckle body 701, a front buckle 702 arranged on the front buckle body 701, and a spring plate 703. Among them, the bottom of the front buckle 702 is an arc part, and a clamping groove is arranged at the upper end of the arc part; the spring plate 703 is a U-shaped structure, one end of the spring plate 703 is installed on the front buckle body 701, and the other end is connected to an elastic limiting part 704; a front buckle bump 12 is arranged at the front end of the strip 5; when the hinge body 1 is installed on the hinge seat 2, the front buckle bump 12 is located between the elastic limiting part 704 and the front buckle 702. Through the above setting, when installing the front buckle 7 on the strip 5, it is necessary to ensure that the front buckle bump 12 on the strip 5 is located between the elastic limiting part 704 and the front buckle 702; in this way, when the hinge body 1 is installed on the hinge seat 2, the arc part at the bottom of the front buckle 702 in the front buckle 7 will contact the front clamping position on the hinge seat 2. During the mutual extrusion process, the front clamping position will cause the front buckle 7 to rotate clockwise. At this time, under the limitation of the front buckle bump 12 on the elastic limiting part 704, the U-shaped spring plate 703 will undergo elastic deformation, that is, the front buckle 702 rotates clockwise against the elastic force of the spring plate 703. When the front clamping position passes over the arc part at the bottom of the front buckle 702 and enters the clamping groove above it, the front buckle 702 will rotate counterclockwise under the elastic force reset of the spring plate 703, so that the clamping groove on the front buckle 702 is clamped into the front clamping position of the hinge seat 2, thereby realizing the quick installation of the front buckle 7.

[0032] In this embodiment, the front buckle body 701, the front buckle 702, the spring plate 703, and the elastic limiting part 704 are two groups, which are symmetrically arranged and are of an integral structure.

[0033] See also Figures 1 - 11 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 the upper end of the arc-shaped part is provided with a card slot; 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 provided 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.

[0034] Through the above-mentioned 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 latching position on the hinge seat 2. During the mutual squeezing process, the rear latching position will prompt the tail buckle 9 to overcome the elastic force of the torsion spring 10 and rotate counterclockwise. When the rear latching position passes over the arc-shaped portion at the bottom of the tail buckle 902 and enters the slot above it, the tail buckle 902 will rotate clockwise under the elastic reset of the spring piece 703, so that the slot on the tail buckle 902 is locked into the rear latching position of the hinge seat 2, thereby realizing the rapid installation of the tail buckle 9.

[0035] See also Figures 1 - 11 Two positioning holes 201 are symmetrically provided on the hinge seat 2; a positioning portion 11 cooperating with the positioning hole 201 is provided on the clamping strip 5 at a position corresponding to the positioning hole 201; by providing 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, thereby helping to achieve rapid installation between the hinge body 1 and the hinge seat 2.

[0036] See also Figures 1 - 11 , a limit block 202 is provided on the hinge seat 2, 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 card strip 5, which can prevent the hinge seat 2 and the hinge body 1 from shifting left and right.

[0037] See also Figures 1 - 11 The clip strip 5 is a hollow structure, which helps to reduce the weight of the clip strip 5 and reduce its manufacturing cost.

[0038] See also Figures 1 - 11 A limit adjustment wire 3 is provided on the hinge body 1, and a U-shaped groove 501 is provided on the clamping strip 5 to cooperate with the limit adjustment wire 3; 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.

[0039] 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 hinge, and no further description will be given again.

[0040] See also Figure 12 and Figure 13 , Figure 12 and Figure 13 What is shown is another embodiment of the quick disassembly structure of concealed hinges for doors and windows of the present invention, the main difference being that the structure of the hinge base 2 is different and the two sides of the hinge base 2 do not extend outwards.
