The hinge for shower room of the embodiment is provided with the connecting seat 25 on the movable hinge 22, the hinge cavity 231 and the second hinge hole 251 are machined on the connecting seat 25, the buffer mechanism 23 is matched and installed with the connecting seat 25, then the fixed hinge 12 is hinged with the movable hinge 22 through the hinge shaft 24, then the fixed pressing plate 11 is oppositely arranged with the fixed hinge 12, and the movable pressing plate 21 is oppositely arranged with the movable hinge 22, so that the hinge parts are more convenient to machine and assemble, the difficulty is reduced, the efficiency of hinge machining and assembly is improved, and the production cost is reduced.

[0025] In the embodiment, the buffering mechanism 23 comprises a buffering seat 232, a buffering spring 233, a buffering roller 234 and a buffering pivot 235. The front end and the rear end of the connecting seat 25 are respectively provided with a front sliding groove 252 and a rear sliding groove 253 for limiting the movement of the buffering seat 232. The buffering seat 232 is provided with a front sliding strip 2321 and a rear sliding strip 2322 which are respectively matched with the front sliding groove 252 and the rear sliding groove 253. When the buffering seat 232 is assembled with the connecting seat 25, the front sliding strip 2321 and the front sliding groove 252 are matched to limit the movement, and the rear sliding strip 2322 and the rear sliding groove 253 are matched to limit the movement. The buffering seat 232 can slide forward and backward relative to the connecting seat 25. The connecting seat 25 comprises a limiting baffle 254, and the buffering seat 232 is straddled on the limiting baffle 254. The two ends of the buffering spring 233 are respectively abutted against the rear end of the buffering seat 232 and the limiting baffle 254. The buffering roller 234 is installed at the front end of the buffering seat 232 through the buffering pivot 235. Specifically, the front end of the buffering seat 232 is provided with a roller mounting position 2323 which can accommodate the buffering roller 234 and a first rotating hole 2324 through which the buffering pivot 235 passes. The first rotating hole 2324 is arranged on both sides of the roller mounting position 2323. The buffering roller 234 is provided with a second rotating hole 2341 through which the buffering pivot 235 passes. The middle part of the buffering pivot 235 is matched with the second rotating hole 2341. The two ends of the buffering pivot 235 are matched with the first rotating hole 2324 on both sides of the roller mounting position 2323. The outer side wall of the buffering roller 234 is tightly attached to the outer side wall of the hinged part 121 under the elastic force of the buffering spring 233. When the movable part 2 rotates, the buffering roller 234 rolls along the outer side wall of the hinged part 121. The outer side wall of the hinged part 121 comprises a free section 1211 which is free to rotate when matched with the buffering roller 234 and a return section 1212 which automatically guides the movable part 2 to return when matched with the buffering roller 234. The free section 1211 is a circular arc structure with the center of the circle located on the center axis of the hinged shaft 24. The return section 1212 is a curved structure which is concave to the free section 1211. Under the elastic force of the buffering spring 233, the buffering roller 234 continuously applies pressure to the hinged part 121.When the free section 1211 of the hinge part 121 cooperates with the buffer roller 234, the pressure applied by the buffer roller 234 to the free section 1211 is perpendicular to the tangent direction of the two, so in this state, the arbitrary position of the movable shower door stops when the external force disappears; when the return section 1212 cooperates with the buffer roller 234, the pressure applied by the buffer roller 234 to the return section 1212 is not perpendicular to the tangent direction of the two, under the pressure of the buffer roller 234, a torque force is generated on the hinge part 121 relative to the hinge shaft 24, driving the movable part 2 to automatically rotate the movable shower door to the return position until the movable shower door rotates to the state that the pressure applied by the buffer roller 234 to the return section 1212 is perpendicular to the tangent direction of the two, thereby realizing that the movable shower door can automatically return and close when it is closed to a certain extent, and reaching the completely closed state.

[0026] In the embodiment, the side of the limiting baffle 254 facing the hinge part 121 is provided with a rotating gasket 26, and the rotating gasket 26 is provided with an arc-shaped inner recess surface 261 abutting against the outer side wall of the hinge part 121, and the arc-shaped inner recess surface 261 is adapted to the outer side wall of the hinge part 121. Through the abutting pressure of the rotating gasket 26 to the hinge part 121 and the adaptation of the arc-shaped inner recess surface 261, the rotation of the movable part 2 can be more stable.

[0027] In the embodiment, the outer side wall of the connecting seat 25 is provided with a waterproof gasket 27, which seals the outer side of the second hinge hole 251 and the rear end of the connecting seat 25, so that the inside of the connecting seat 25 is sealed, preventing water from entering the inside of the connecting seat 25 from the second hinge hole 251 or the rear end of the connecting seat 25, and affecting the rotation of the movable part 2.

[0028] In the embodiment, in order to improve the tightness and safety of the installation between the fixed part 1 and the fixed partition, and between the movable part 2 and the movable shower door, the opposite side of the fixed pressing plate 11 and the fixed hinge 12 is provided with a rubber pad, and the fixed pressing plate 11 and the fixed partition are attached through the rubber pad, and the fixed hinge 12 and the fixed partition are also attached through the rubber pad, thereby preventing the problems of unstable connection or connection too tight to damage the glass when the fixed part 1 and the fixed partition are installed and connected. Similarly, the opposite side of the movable pressing plate 21 and the movable hinge 22 is provided with a rubber pad, and the movable pressing plate 21 and the movable shower door are attached through the rubber pad, and the movable hinge 22 and the movable shower door are also attached through the rubber pad.

[0029] The above only describes the preferred embodiments of the present application, and any technical solutions achieving the same purpose by basically the same means shall fall within the protection scope of the present application.
