[0019] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0020] REFERENCE Figs. 1 to 3The side sliding hinge of the embodiment comprises a sliding rail 1 fixed with a window frame, a sliding block 2 slidingly installed on the sliding rail 1, a second connecting rod 3 fixed with a window sash and hingedly connected with the sliding block 2 at one end, and a first connecting rod 4 hingedly connected with the sliding rail 1 at one end and the other end of the second connecting rod 3; the second connecting rod 3 and the first connecting rod 4 and the second connecting rod 3 and the sliding block 2 are all provided with detachable connecting structures 5. Taking the detachable connecting structure 5 between the first connecting rod 4 and the second connecting rod 3 as an example, the detachable connecting structure 5 connecting the two is a lock catch structure, which comprises a cylindrical pin shaft 51 fixed perpendicularly on the first connecting rod 4, the pin shaft 51 is provided with a clamping groove 511 around the circumference, an installation cavity provided in the second connecting rod 3, a U-shaped clamping spring 52 installed in the installation cavity along the length direction of the second connecting rod 3, the two arms of the U-shaped clamping spring 52 are provided with a vertical installation hole 53 and an unlocking hole 54, the installation hole 53 penetrates through the second connecting rod 3, and in the reset state, the two arms of the U-shaped clamping spring 52 radially expose the edges of the installation hole 53 and the unlocking hole 54; the diameter of the pin shaft 51 and the installation hole 53 is matched, when the pin shaft 51 penetrates through the installation hole 53, the U-shaped clamping spring 52 is elastically clamped in the clamping groove 511, and when the two arms of the U-shaped clamping spring 52 are separated from the clamping groove 511 by supporting the two arms from the unlocking hole 54, the first connecting rod 4 and the second connecting rod 3 can be detachably hingedly connected and installed.

[0021] The side sliding hinge is provided with the detachable connecting structure 5, during installation, the sliding rail 1 is first fixed with the window frame, the second connecting rod 3 is then fixed with the window sash, and then the two ends of the second connecting rod 3 are assembled with the first connecting rod 4 and the sliding block 2 through the detachable connecting structure 5, which simplifies the installation and improves the safety. During installation, only the installation hole 53 of the second connecting rod 3 needs to be aligned with the pin shaft 51 of the first connecting rod 4 and clamped in, the U-shaped clamping spring 52 is automatically clamped in the clamping groove 511 to complete the installation and can be relatively rotated, and when the two arms of the U-shaped clamping spring 52 are separated by supporting the two arms from the unlocking hole 54 with a special tool, the installation and disassembly are simple.

[0022] In a preferred scheme, the second connecting rod 3 of the embodiment is provided with two limiting holes 55 corresponding to the free ends of the two arms of the U-shaped clamping spring 52, and the free ends of the two arms of the U-shaped clamping spring 52 are respectively inserted into the two limiting holes 55 after being bent. Further, the limiting holes 55 are elongated holes provided along the length direction of the U-shaped clamping spring 52. The limiting holes 55 increase the strength required for the deformation of the U-shaped clamping spring 52, ensure the clamping strength of the pin shaft 51, and make the structure more reliable. The limiting holes 55 are elongated holes, so that the free ends of the U-shaped clamping spring 52 can only move along the length direction of the limiting holes 55 during deformation, further increasing the strength required for the deformation of the U-shaped clamping spring 52.

[0023] In a preferred embodiment, the second connecting rod 3 has a flat base plate 31, a cover plate 32 fixedly attached to one side surface of the base plate 31, and a recess 321 formed on the side surface of the base plate 31 by stamping. The recess 321 and the base plate 31 form the mounting cavity. The mounting cavity is formed by attaching the cover plate 32 to the base plate 31, which simplifies the production and assembly.

[0024] In a preferred embodiment, the mounting cavity has an arc-shaped side wall 3211 adapted to abut against the outer side of the bent end of the U-shaped spring 52. The arc-shaped side wall 3211 limits the outer side of the bent end of the U-shaped spring 52, which not only improves the stability of the U-shaped spring 52, but also increases the force required for the deformation of the U-shaped spring 52.

[0025] In a preferred embodiment, the mounting cavity has a limiting column 56 fixedly arranged vertically therein and adapted to abut against the inner side of the bent end of the U-shaped spring 52. The limiting column 56 limits the inner side of the bent end of the U-shaped spring 52, which improves the stability of the U-shaped spring 52.

[0026] In a preferred embodiment, the mounting hole 53 is located at the middle of the U-shaped spring 52, and the unlocking hole 54 is located between the mounting hole 53 and the free end of the U-shaped spring 52. The mounting hole 53 is far away from the free end of the U-shaped spring 52, and thus requires a greater force for deformation, while the unlocking hole 54 requires a smaller force, which ensures the bonding strength and facilitates the unlocking.

[0027] In a preferred embodiment, the distance between the two arms of the U-shaped spring 52 corresponding to the position of the unlocking hole 54 is smaller than the distance between the two arms of the U-shaped spring 52 corresponding to the position of the mounting hole 53, and the diameter of the unlocking hole 54 is smaller than the diameter of the mounting hole 53. The larger diameter of the mounting hole 53 ensures the bonding strength, while the smaller diameter of the unlocking hole 54 reduces the probability of accidental unlocking.

[0028] The above description is not intended to limit the technical scope of the present application. Any modification, equivalent change, and modification made to the above embodiments according to the technical essence of the present application are still within the scope of the technical solution of the present application.
