[0023] Please combine Figures 1 to 5A quickly disassembled buffer hinge for a bathroom intermittent door is shown, comprising a fixed seat 1 and a movable seat 2, wherein a first sleeve 11 protruding outward is provided at a lower end of one side of the fixed seat 1, and a second sleeve 21 protruding outward is provided at an upper end of one side of the movable seat 2, wherein the first sleeve 11 and the second sleeve 21 are rotatably connected via an energy storage mechanism 3; the energy storage mechanism 3 provides an elastic force for the fixed seat 1 and the movable seat 2 to rotate back to their original positions;

[0024] Specifically, the energy storage mechanism 3 includes a torsion spring seat 31 and a torsion spring 32. The torsion spring seat 31 is hollow and tubular. The two ends of the torsion spring seat 31 are respectively inserted into the first sleeve 11 and the second sleeve 21. The torsion spring 32 is arranged in the torsion spring seat 31. The two ends of the torsion spring 32 are respectively bent to form a first connecting portion 321 and a second connecting portion 322. The inner bottom of the first sleeve 11 is provided with a clamping groove 111. The first connecting portion 321 extends out of the torsion spring seat 31 and is clamped with the clamping groove 111. A latch 311 is arranged on the inner top of the torsion spring seat 31. The second connection portion 322 is connected to the latch 311; to be precise, the first connection portion 321 and the second connection portion 322 are U-shaped, and the clamping groove 111 is a cross groove. During installation, the second connection portion 322 of the torsion spring 32 is correspondingly inserted into the torsion spring seat 31, and the latch 311 is inserted into the torsion spring seat 31 and passes through the second connection portion 322, so that one end of the torsion spring 32 is connected to the torsion spring seat 31, and then the first connection portion 321 of the torsion spring 32 is correspondingly inserted into the cross groove of the first sleeve 11, and the first step of installing the energy storage mechanism 3 is completed;

[0025] The upper end of the outer side of the torsion spring seat 31 is provided with a limiting hole 312. To be precise, a plurality of limiting holes 312 are provided, and the plurality of limiting holes 312 are distributed on the outer wall surface of the torsion spring seat 31 along the axis of the torsion spring seat 31. A screw hole 211 is opened at the side wall of the second sleeve 21 close to the movable seat 2. A top screw 212 is screwed in the screw hole 211. The top screw 212 is twisted to move it toward one of the limiting holes 312. The top screw 212 is clamped in the limiting hole 312 in the locked state, so that the torsion spring seat 31 is fixed in the second sleeve 21. When the fixed seat 1 and the movable seat 2 rotate and unfold relative to each other, the torsion spring 32 is compressed and stored in the torsion spring seat 31, and provides an elastic force when the fixed seat 1 and the movable seat 2 are relatively closed and returned, so that the door leaf realizes the self-closing function; it should be understood that, refer to Figure 5 When performing rescue work, it is only necessary to rotate the door leaf for a certain distance, and then use a tool to rotate the top screw 212 to disengage the top screw 212 from the limiting hole 312. The torsion spring seat 31 rotates in the first sleeve 11 and the second sleeve 21 when it is disengaged from the limit of the top screw 212. At this time, the first sleeve 11 and the second sleeve 21 are no longer restricted by the potential energy of the torsion spring 32, and the door leaf equipped with the movable seat 2 can be easily removed.

[0026] The end of the torsion spring seat 31 is provided with an inner hexagonal groove 313. After the buffer hinge is installed, the top screw 212 is first twisted out, and the outer hexagonal wrench is inserted into the inner hexagonal groove 313 to rotate the torsion spring seat 31. Then, according to different self-closing door closing speed requirements, the top screw 212 is twisted into one of the corresponding limit holes 312 to adjust the door closing speed.

[0027] The fixed seat 1 or the movable seat 2 is provided with a buffer mechanism 4, which provides a buffering force for the fixed seat 1 and the movable seat 2 when the buffer hinge is in a closed state; to be precise, the buffer mechanism 4 is two groups of buffer components, and the buffer component includes a damper 41 and a slider 42. An active cavity 12 is opened on the rear side of the fixed seat 1, and the damper 41 and the slider 42 are arranged in the active cavity 12. One end of the damper 41 abuts against the wall of the active cavity 12, and the other end abuts against the slider 42. The movable seat 2 applies force on the slider 42 before rotating back to a fully closed state. It should be understood that when the buffer hinge is closed, the side of the movable seat 2 contacts the end of the slider 42, and the damper 41 provides a buffering force for the energy storage mechanism 3, so that the buffer hinge closes slowly; specifically, the end of the slider 42 away from the damper 41 is arc-shaped, and this structure makes the buffer hinge smoother when closing.

[0028] Specifically, guide blocks 421 are provided on both side edges of the slider 42, and limit blocks 422 are provided at the ends of the guide blocks 421. Guide grooves 121 are provided on both side walls of the active cavity 12. The guide blocks 421 slide in cooperation with the guide grooves 121, and steps 122 are formed at the ends of the guide grooves 121. When the buffer hinge is in the unfolded state, the steps 122 abut against the limit blocks 422. On the one hand, the guide blocks 421 cooperate with the guide grooves 121 on the both side walls of the active cavity 12 to enable the slider 42 to move more smoothly in the active cavity 12. On the other hand, by providing the limit blocks 422 at the ends of the guide blocks 421, when the slider 42 slides in the active cavity 12, the setting of the limit blocks 422 prevents the slider 42 from sliding out of the active cavity 12 as a whole.

[0029] Specifically, an installation cavity is provided on the front end surface of the fixed seat 1 and the movable seat 2, and a plurality of installation holes are provided in the installation cavity. Screws are used to pass through the installation holes for installation. After the fixed seat 1 and the movable seat 2 are fixed, the installation cavity is provided with a decorative cover 5 adapted thereto. To be precise, the decorative cover 5 is snapped into the installation cavity. The decorative cover 5 is used to cover the screws in the installation cavity to prevent the screws from being exposed, making the door body more beautiful.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
