[0036] Example 1

[0037] like Figures 1 to 7As shown, a hinge described in an embodiment of the present invention includes a fixed part 1 and a movable part 2 that rotates around the fixed part 1, the fixed part 1 is provided with an open accommodating cavity 10, the movable part 2 is installed in the accommodating cavity 10 of the fixed part 1, and the movable part 2 is provided with a mounting portion that passes through the accommodating cavity 10, the opening includes a first opening and a second opening, a torsion spring 23 that is twisted along a certain angle in the rotation direction is installed between the movable part 2 and the fixed part 1, the two ends of the torsion spring 23 respectively abut against the movable part 2 and the fixed part 1, and the elastic force generated by the torsion spring 23 to reset drives the mounting portion of the movable part 2 to rotate from the first opening to the second opening, so that the movable part 2 rotates around the fixed part 1 and opens.

[0038] In this embodiment, the opening of the accommodating cavity 10 includes a first opening and a second opening perpendicular to each other. The first opening and the second opening are adjacent to each other and are connected to each other. The movable member 2 is installed in the accommodating cavity 10. The mounting portion of the movable member 2 protrudes outward from the accommodating cavity 10 through the first opening or the second opening. The mounting portion rotates from the first opening on the horizontal side to the second opening on the vertical side. Figure 4 The direction of the arrow is the rotation direction of the movable part 2, and the periphery of the second opening is the mounting part of the fixed part 1. The mounting part of the movable part 2 and the mounting part of the fixed part 1 are both flat, which can be fitted and fixed on the door body and the door frame. In the closed state, the mounting part of the movable part 2 protrudes outward through the first opening, and the mounting part of the movable part 2 is perpendicular to the mounting part of the fixed part 1. In the open state, the mounting part of the movable part 2 protrudes outward through the second opening, and the mounting part of the movable part 2 is parallel to the mounting part of the fixed part 1.

[0039] In this embodiment, the movable member 2 is provided with an open recess 21, which is mounted within the accommodating chamber 10. The recess 21 opens in the same direction as the opening of the accommodating chamber 10. First pin holes 211 are provided on opposite side walls of the recess 21, and second pin holes 13 are provided on the side walls of the accommodating chamber 10. The first and second pin holes 211 and 13 are coaxially arranged. The ends of a rotating shaft 22 pass through the first and second pin holes 211 and 13, respectively. A sleeve 24 is mounted on the rotating shaft 22, which is fitted with a torsion spring 23 that is twisted along the rotational direction by a certain angle. A track groove 210 is provided at the bottom of the recess 21, and a spring hole 11 is provided on the bottom wall of the accommodating chamber 10 at a position corresponding to the track groove 210. One end of the torsion spring 23 passes through the track groove 210 and into the spring hole 11, while the other end abuts against the side wall of the recess 21. Due to the twisting applied during installation, the torsion spring 23 generates a torsional force on the side walls of the recess 21, driving the movable member 2 to rotate about the rotating shaft 22 from the first opening to the second opening.

[0040] In this embodiment, a first pin hole 211 is provided on the side wall of the groove 21, and a second pin hole 13 is provided on the side wall of the accommodating cavity 10. The first pin hole 211 and the second pin hole 13 are coaxially arranged, and the two ends of the rotating shaft 22 pass through the first pin hole 211 and the second pin hole 13 in sequence. The fixing part 1 is installed with an axis baffle 4 perpendicular to the outer wall of the rotating shaft 22. The axis baffle 4 is provided with a limiting groove 41 for axially limiting the end of the rotating shaft 22. The limiting groove 41 is arranged opposite to the first pin hole 211 or the second pin hole 13. The side wall of the limiting groove 41 is in limiting contact with the outer periphery of the rotating shaft 22, and the bottom wall of the limiting groove 41 is in limiting contact with the end face of the rotating shaft 22.

[0041] In this embodiment, a third opening 12 is provided on the accommodating cavity 10, and a rotating baffle is provided on the side of the groove 21 opposite to the opening. The movable part 2 is installed in the accommodating cavity 10, and the rotating baffle passes through the third opening 12 of the accommodating cavity 10. When the movable part 2 rotates from the first opening to the second opening, the rotating baffle moves along the opening in a direction perpendicular to the rotation axis 22 until one side of the rotating baffle contacts the upper edge of the third opening 12.

[0042] The hinge described in the present invention is simple to assemble, compact in structure, and occupies little space. It can be installed on household appliances, doors, windows, or boxes. The door body is opened by the elastic force of the spring without relying on manpower, which improves the user experience. Under the action of the torsion spring 23, the door body will not be automatically closed by the external environment. After closing, the door body needs to be locked.

The opening includes a first opening and a second opening. A third opening 12 for the rotating baffle to pass through is provided on the bottom wall of the accommodating cavity 10, and the third opening 12 extends in an arc shape along the bottom wall. The two sides of the rotating baffle are respectively in limited contact with the two side walls of the third opening 12 parallel to the axial direction of the rotating shaft 22 in the closed or open state.

[0045] In this embodiment, the periphery of the first opening is provided with a flat flange perpendicular to the direction in which the arc extends. The flange is arranged parallel to the mounting portion of the movable member 2 in the closed state. Two mounting posts 15 are provided on the flange near the upper edge of the third opening 12. The two mounting posts 15 are fixed to either side of the opening. Buffer pads 3 are mounted on the mounting posts 15. The two buffer pads 3 are arranged opposite each other, and the distance between the two buffer pads 3 is less than the width of the rotating baffle along the rotation axis 22. Preferably, the buffer pads 3 are rubber structural members. When the movable member 2 rotates around the fixed member 1, the rotating baffle on the movable member 2 rotates along the opening toward the flap. After the movable baffle rotates to the buffer pads 3, it is clamped between the two oppositely arranged buffer pads 3. The two ends of the movable baffle are in contact with the buffer pads 3 and rotate slowly, thereby preventing the torsion of the torsion spring 23 from causing a large impact and collision with the movable baffle cabinet fixed member 1.

[0046] In this embodiment, spring holes 11 are provided on both sides of the third opening 12 for inserting one end of the torsion spring 23. A groove 21 is provided on the movable part 2, and a penetrating track groove 210 is provided on the bottom wall of the groove 21. The spring holes 11 are arranged opposite to the track groove 210 of the movable part 2. One end of the torsion spring 23 passes through the track groove 210 and is inserted into the spring hole 11, and the other end abuts against the side wall of the groove 21. A first pin hole 211 is provided on the side wall of the groove 21, and a second pin hole 13 is provided on the side wall of the accommodating cavity 10. The first pin hole 211 and the second pin hole 13 are coaxially arranged, and the two ends of the rotating shaft 22 pass through the first pin hole 211 and the second pin hole 13 in sequence. The fixing member 1 is perpendicular to the outer wall of the rotating shaft 22 and the shaft baffle 4 is installed. The shaft baffle 4 is provided with a limiting groove 41 for axially limiting the end of the rotating shaft 22. The limiting groove 41 is arranged opposite to the first pin hole 211 or the second pin hole 13. The side wall of the limiting groove 41 is in contact with the outer periphery of the rotating shaft 22. The limiting groove 41 The bottom wall is in limited contact with the end face of the rotating shaft 22. In order to facilitate the installation of the rotating shaft 22 and the torsion spring 23, the second pin hole 13 is a rectangular hole. The rectangular hole extends perpendicular to the bottom wall of the accommodating cavity 10. One end of the rectangular hole away from the bottom wall of the accommodating cavity 10 is corresponding to the first pin hole 211 on the movable part 2 for the rotating shaft 22 to pass through, which facilitates the installation and disassembly of the rotating shaft 22. The rectangular hole extends from the bottom wall of the accommodating cavity 10 to the position corresponding to the first pin hole 211. The two ends of the rotating shaft 22 pass through the first pin hole 211 of the movable part 2 and the rectangular hole of the fixed part 1 in sequence.

[0047] In this embodiment, the periphery of the second opening extends horizontally in a direction perpendicular to the opening direction of the second opening to form a mounting portion of the fixing member 1. For the convenience of description, the mounting portion of the fixing member 1 is referred to as the first mounting portion 14, and the mounting portion of the movable member 2 is the second mounting portion 25. The first mounting portion 14 and the second mounting portion 25 are planes.

The fixing member 1 and the movable member 2 are fixed by bolts. Preferably, the second mounting hole 251 is a countersunk hole.

[0048] Example 3

[0049] like Figure 6 As shown, the movable part 2 described in this embodiment includes an open groove 21, and a coaxial first pin hole 211 is provided on the two opposite side walls of the groove 21, and a second pin hole 13 is provided on the side wall of the accommodating cavity 10. The first pin hole 211 and the second pin hole 13 are coaxially arranged, and the two ends of the rotating shaft 22 are respectively inserted into the first pin hole 211 and the second pin hole 13 in sequence. A penetrating track groove 210 is provided inside the groove 21, and a spring hole 11 arranged opposite to the track groove 210 is provided on the bottom wall of the accommodating cavity 10. One end of the torsion spring 23 passes through the track groove 210 and is inserted into the spring hole 11, and the other end abuts against the side wall of the groove 21.

[0050] In this embodiment, the track groove 210 extends perpendicular to the axial direction of the rotating shaft 22, and the track groove 210 extends from the bottom wall of the groove 21 to the side wall of the groove 21 that contacts the end of the torsion spring 23, so that when the movable part 2 rotates from the first opening to the second opening, the track groove 210 and the end of the torsion spring 23 inserted into the spring hole 11 of the fixed part 1 produce relative movement.

[0051] In this embodiment, movable member 2 is provided with a rotating baffle that protrudes in the direction opposite to the opening of recess 21. A third opening 12 is formed on the bottom wall of accommodating chamber 10, through which the rotating baffle passes. Third opening 12 corresponds to the first and second openings. Under the action of torsion spring 23, the rotating baffle of movable member 2 rotates along the sidewall of third opening 12 perpendicular to the axial direction of rotation axis 22. In the open state, the rotating baffle is in positional contact with the upper edge of the opening; in the closed state, the rotating baffle is in positional contact with the lower edge of the opening.

[0052] In this embodiment, the plane on one side of the opening of the groove 21 parallel to the bottom wall of the groove 21 is the mounting portion of the movable member 2, and the mounting portion of the movable member 2 is the second mounting portion 25. The second mounting portion 25 is provided with a second mounting hole 251. In the closed state, Figure 1 As shown, the second mounting portion 25 and the first mounting portion 14 are vertically arranged. In the open state, as shown in FIG. Figure 4 As shown, the second mounting portion 25 and the first mounting portion 14 are arranged in parallel.

[0053] Example 4

The fixed part 1 and the movable part 2 can rotate around the rotating shaft 22. The axial extension direction of the rotating shaft 22 is perpendicular to the rotation direction of the movable part 2 from the first opening to the second opening. Two torsion springs 23 twisted along the rotation direction by a certain angle are provided on the rotating shaft 22. The torsion springs 23 generate a reset elastic force, and the elastic force of the torsion springs 23 causes the movable part 2 to rotate relatively around the rotating shaft 22.

[0055] In this embodiment, the torsion spring 23 includes a first end that is in limited contact with the fixed part 1 and a second end that is in limited contact with the movable part 2. The first end of the torsion spring 23 passes through the track groove 210 of the movable part 2 and is inserted into the spring hole 11 on the bottom wall of the accommodating chamber 10. The spring is twisted by a certain angle along the rotation direction of the spring. The second end of the spring is limited on the side wall of the groove 21. Since the spring is in a forced state, the second end of the spring provides an elastic force to the side wall of the groove 21, so that the movable part 2 rotates open from the first opening to the second opening of the accommodating chamber 10.

[0056] In this embodiment, a sleeve 24 is provided on the rotating shaft 22, and a torsion spring 23 is provided on the outer periphery of the sleeve 24, which can avoid the noise generated by the direct contact and friction between the rotating shaft 22 and the torsion spring 23 when the movable part 2 rotates around the fixed part 1 to open or close. One end of the sleeve 24 protrudes radially to form a shoulder, which limits the axial position of the torsion spring 23.

[0057] Example 5

[0058] like Figure 8 As shown, an axis baffle 4 is installed on the outer side wall opposite to the fixing part 1 described in this embodiment, and a limiting groove 41 is provided on the axis baffle 4 for axially limiting the end of the rotating shaft 22. The limiting groove 41 is arranged opposite to the first pin hole 211 or the second pin hole 13, and the side wall of the limiting groove 41 is in limiting contact with the outer periphery of the rotating shaft 22, and the bottom wall of the limiting groove 41 is in limiting contact with the end face of the rotating shaft 22.

[0059] In this embodiment, the second pin hole 13 is a rectangular hole, which is convenient for the installation of the rotating shaft 22. The shaft baffle 4 limits the movement of the rotating shaft 22 toward both sides of the fixed part 1 and along the extension direction of the long hole. The shaft baffle 4 is provided with a limiting groove 41 at the corresponding position of the pin hole. The end of the rotating shaft 22 passes through the pin hole of the movable part 2 and the rectangular hole of the fixed part 1 in turn and then extends into the limiting groove 41. The side wall of the limiting groove 41 is in limiting contact with the outer periphery of the rotating shaft 22, and the bottom wall of the limiting groove 41 is in limiting contact with the end face of the rotating shaft 22.

[0060] In this embodiment, the shaft baffle 4 is fitted and fixed to both sides of the fixing member 1. The shaft baffle 4 is a rectangular block structure. The side of the shaft baffle 4 that is fitted to the fixing member 1 protrudes toward the fixing member 1 to form a protrusion, which extends into the rectangular hole of the fixing member 1. The top of the protrusion corresponds to the first pin hole 211 to form the side wall of the limiting groove 41. The side of the protrusion facing the limiting groove 41 is fitted with the outer periphery of the rotating shaft 22, and both ends of the rotating shaft 22 extend into the inside of the limiting groove 41.

[0061] In this embodiment, one end of the shaft stopper 4 is provided with a mounting portion protruding in the same direction as the protruding portion. A threaded hole 42 is provided on the mounting portion. The shaft stopper 4 is detachably fixed to the fixing member 1 by bolts.

[0062] Example 6

[0063] This embodiment introduces a disinfection cabinet, including a disinfection cabinet body and a door body installed on the disinfection cabinet body, using the hinge described in any one of the above embodiments one to five, the hinge including a fixed part 1 and a movable part 2, the movable part 2 is fixed on the door body, the fixed part 1 is fixed on the disinfection cabinet body, the movable part 2 and the fixed part 1 are both fixed by bolts, the hinge is installed on the side where the door body and the disinfection cabinet body rotate relative to each other, the first mounting part 14 is fit and fixed to the edge of the disinfection cabinet body, the second mounting part 25 is fixed to the edge of the door body, and the torsion spring 23 pushes the mounting part of the movable part 2 to rotate from the first opening to the second opening, so that the door body rotates 90° around the disinfection cabinet body to open.

[0064] The door is installed in the open state, with the first mounting portion 14 of the fixing member 1 fixed to the edge of the disinfection cabinet body, and the second mounting portion 25 of the movable member 2 fixed to the edge of the door body adjacent to the edge of the disinfection cabinet, and the movable member 2 and the fixing member 1 are fixed to the door body and the disinfection cabinet body respectively by bolts. The present invention is easy to install and disassemble and has strong versatility.

[0065] In the closed state and the open state, the door body is in two positions perpendicular to each other.

[0066] Since the torsion spring 23 has a certain torsional force, the door body needs to be locked after it is closed, for example, by means of a buckle and a slot. A buckle is provided on the disinfection cabinet body, and a slot is provided at the corresponding position of the door body. When the buckle is disengaged from the slot, the door body automatically opens, or other methods are used to lock it. When the door body needs to be opened and unlocked, the movable part 2 rotates around the fixed part 1 under the elastic force of the torsion spring 23, driving the door body to rotate and open. The door body relies on the torsion force of the torsion spring 23 during the opening process, and does not need to rely on external force. After the door body is opened, it will automatically close due to the elastic force of the torsion spring 23 and will not be affected by external wind force or other factors.
