[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a buffer-type stainless steel hinge, which includes a hinge assembly 1 and a buffer assembly 2. By setting the hinge assembly 1 and the buffer assembly 2, the hinge is driven by the force when it rotates, and buffer protection is provided during the opening and closing of the hinge, thereby reducing vibration and noise during the opening and closing of the hinge. In addition, the buffer strength can be manually adjusted according to the installation requirements, thereby improving the applicability of the hinge.

[0033] Specifically, the hinge assembly 1 includes a movable hinge 11, a movable sleeve 17 fixed on one side of the movable hinge 11, a fixed hinge 12 on one side of the movable hinge 11, a fixed sleeve 16 fixed on one side of the fixed hinge 12, an intermediate sleeve 19 fixed at the middle of one side of the fixed sleeve 16, a rotating shaft 14 slidably connecting the inner cavities of the fixed sleeve 16 and the movable sleeve 17, and an annular groove 110 formed on the outer ring of the intermediate sleeve 19.

[0034] Specifically, the buffer assembly 2 is located on the outer ring of the intermediate sleeve 19 and includes a rotating sleeve 21 that is movably fitted inside the annular groove 110. Torsion springs 22 are provided at the top and bottom of the intermediate sleeve 19. An adjustment groove 24 is provided on the inner wall of the annular groove 110. A shaped cavity 26 is provided on the surface of the rotating sleeve 21. An adjustment component 27 is provided inside the shaped cavity 26.

[0035] Example 2, refer to Figures 2-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, it also includes mounting holes 13 on the surfaces of both the movable hinge 11 and the fixed hinge 12, and a connecting sleeve 15 between the fixed sleeve 16 and the movable sleeve 17.

[0037] Specifically, a first slot 18 is provided on one side of the movable sleeve 17, and a second slot 25 is provided in the inner cavity of the rotating sleeve 21.

[0038] Specifically, the top and bottom of the intermediate sleeve 19 are provided with first rotating grooves 28, and the top and bottom of the inner wall of the annular groove 110 are provided with second rotating grooves 23.

[0039] Specifically, one end of the torsion spring 22 is fixed to the inner cavity of the first slot 18, and the other end of the torsion spring 22 is fixed to the second slot 25.

[0040] Specifically, the adjusting member 27 includes an adjusting rod 271 that is slidably connected inside the irregular cavity 26, with one end of the adjusting rod 271 located inside the adjusting groove 24.

[0041] By setting multiple adjustment slots 24, the adjustment rod 271 can be fixed in different positions, so that the rotating sleeve 21 can be stably fixed after rotation, ensuring the gradual adjustment of the buffer strength.

[0042] Specifically, a special-shaped baffle 274 is fixed to the other end of the adjusting rod 271, a retaining ring 273 is fixed to the outer ring of the adjusting rod 271, and a spring 272 is sleeved on the outer ring of the adjusting rod 271.

[0043] By setting a manually rotatable irregular baffle 274, the buffer strength can be adjusted without the need for additional tools, simply by rotating it manually, which improves the ease of operation and lowers the operating threshold.

[0044] By setting spring 272, when the irregular baffle 274 rotates to the exposed outlet of the irregular cavity 26, it can drive the retaining ring 273 and the adjusting rod 271 to pop out automatically, so that the adjusting rod 271 is disengaged from the current adjusting groove 24.

[0045] By setting a retaining ring 273, the adjusting rod 271 can be limited when it pops out, preventing the adjusting rod 271 from completely disengaging from the irregular cavity 26, and at the same time preventing the spring 272 and the irregular baffle 274 inside the irregular cavity 26 from falling off.

[0046] Specifically, one end of the spring 272 is fixed to the inner wall of the irregular cavity 26, and the other end of the spring 272 is fixed to the surface of the retaining ring 273.

[0047] By setting a torsion spring 22, when the door and window are closed, the movable hinge 11 and movable sleeve 17 are rotated, so that the torsion spring 22 generates a stable torque, which buffers and protects the hinge during the closing process, reducing vibration and noise.

[0048] Specifically, one end of the torsion spring 22 passes through the first rotating groove 28 and the second rotating groove 23 in sequence, and the surface of the torsion spring 22 is slidably connected to the inner walls of the first rotating groove 28 and the second rotating groove 23 respectively.

[0049] Specifically, the surface of the irregular baffle 274 is in close contact with the outlet end of the irregular cavity 26, and a rotating plate is fixed on the surface of the irregular baffle 274.

[0050] By setting the irregular baffle 274, it can be used as a "handle" so that after it pops out, it can be manually held to rotate the rotating sleeve 21.

[0051] In use, the movable hinge 11 is movably fitted onto the surface of the pivot 14 via the movable sleeve 17, and the fixed hinge 12 is movably fitted onto the surface of the pivot 14 via the fixed sleeve 16. The fixed hinge 12 is the fixed end, used to fix it in the installation position, and the movable hinge 11 is the movable end, used to fix it on the door or window. The fixed sleeve 16 and the movable sleeve 17 are alternately distributed on the surface of the pivot 14, and the two are connected by the connecting sleeve 15.

[0052] When the doors and windows are closed, the movable hinge 11 and the movable sleeve 17 are rotated. Since one end of the torsion spring 22 is inserted into the first slot 18 on the movable sleeve 17, and the other end of the torsion spring 22 is inserted into the second slot 25 on the fixed sleeve 16, one end of the torsion spring 22 is fixed and the other end is movable. Therefore, the torsion spring 22 will twist. The torsion of the torsion spring 22 is used to buffer and protect the hinge when it is closed.

[0053] When the buffer strength needs to be adjusted, manually rotate the irregular baffle 274 to expose the part that was blocked by the outlet end of the irregular cavity 26. At this time, the spring 272 will reset and pop out, thereby driving the retaining ring 273 and the adjusting rod 271 to pop out, so that the adjusting rod 271 is disengaged from the current adjusting groove 24. At this time, the irregular baffle 274 moves out of the irregular cavity 26, but because the retaining ring 273 blocks it, the adjusting rod 271 will not pop out completely.

[0054] At this time, hold the irregular baffle 274 as a "handle" and rotate it to make the rotating sleeve 21 rotate, and the adjusting rod 271 will rotate accordingly. When it rotates to another adjusting groove 24, press the irregular baffle 274 so that it is located inside the irregular cavity 26 and rotated to the outlet end of the irregular cavity 26 to block and restore it. At this time, the torsion spring 22 is manually pressed to increase the torque. The torque is greater during buffering, thereby achieving the effect of adjusting the buffering strength. Then repeat the above operation to adjust to different levels of buffering strength.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
