Abstract
Description
Technical Field
[0001] This utility model relates to the field of hinge technology, and in particular to a rotating mechanism and hinge. Background Technology
[0002] Hinges are widely used hardware accessories in home furnishings, mainly used for the opening and closing connection between doors and cabinets in furniture. Currently, common hinges on the market mainly include an adjustable mounting base, a hinge cup, and a hinge arm. Generally, the mounting base is fixedly installed on the inner wall of the cabinet, the hinge cup is fixedly installed on the door, one end of the hinge arm is connected to the mounting base, and the other end of the hinge arm is rotatably connected to the hinge cup.
[0003] Since the mounting bracket is the most easily visible part when the door is opened during use, and in order to improve the product's refinement and aesthetics, the design of the hinge mounting bracket tends to be thinner and smaller. Therefore, larger parts such as torsion springs and dampers are designed in the hinge cup, while the easily visible mounting bracket tends to be thinner.
[0004] For example, the invention patent with publication number CN 119177808 A specifically discloses a modular ultra-thin hinge chassis system and hinge. Based on its disclosed technical content and accompanying drawings, paragraph
[0055] of the specification discloses that "the modular ultra-thin hinge chassis system further includes two connecting plates, which are vertically disposed on opposite sides of the connecting strip and extend along the second direction. Each connecting plate is provided with a second positioning hole. The modular ultra-thin hinge chassis system also includes a rotating shaft, which spans between the second positioning holes of the two connecting plates. Both ends of the rotating shaft protrude from the second positioning holes, wherein the protruding portion of the rotating shaft is used for rotatably connecting with the hinge arm, so that the hinge arm can rotate around the axis of the rotating shaft, thereby adjusting the angle between the hinge arm and the connecting strip through the adjusting column." In the aforementioned patent, the rotating shaft passes sequentially through the hinge arm and the second positioning hole of the connecting plate, thereby achieving a rotatable connection between the connecting strip and the hinge arm. However, in practical applications, because the weight of the door is borne by the hinge wall, the rotating shaft deforms under gravity, causing one end of the rotating shaft to easily detach from the second positioning hole of the connecting plate. This prevents adjustment of the angle between the hinge arm and the connecting strip. Even with two limiting plates to limit the rotating shaft, this issue persists in the existing technical documents. Figure 1-2 It can be seen that the length of the limiting plate in the longitudinal direction of the hinge arm is relatively short, and the limiting plate is easy to deform after being subjected to force, so its limiting effect on the rotating shaft is also limited. Utility Model Content
[0005] In order to overcome the defects of the existing technology, this utility model provides a rotating mechanism and a hinge.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a rotating mechanism, including a slide and a connecting seat. The connecting seat has a receiving groove. The bottom of the receiving groove is integrally formed with two limiting plates and two bushings. The two ends of the two limiting plates extend to the two walls of the receiving groove, respectively. The axial direction of the two bushings is perpendicular to the length direction of the limiting plates. One end of the two bushings extends to the other two walls of the receiving groove, respectively. The other end of the two bushings is close to the two limiting plates, and the other end of the two bushings forms a limiting groove with the two limiting plates. The slide is placed in the receiving groove, and the two sides of the slide are integrally formed with hinge plates, and the two hinge plates are hinged to the limiting grooves on both sides by pins.
[0007] As a further embodiment, the two limiting plates and the two bushings are mirror-symmetrical about the center line of the receiving groove.
[0008] As a further embodiment, the hinge plates on both sides are perpendicular to the slide block; Two pins are provided, and the two pins pass through the through holes on the two side walls of the receiving groove, the bushing, and the hinge hole on the hinge plate in sequence, and abut against the two limiting plates respectively. Alternatively, the pin passes through the through hole, bushing, hinge hole on the hinge plate, and limiting plate on one side of the receiving groove, and passes through the limiting plate, hinge hole on the hinge plate, bushing, and through hole on the other side of the receiving groove.
[0009] As a further embodiment, the rotating mechanism further includes a fixed seat, an adjusting member, and an eccentric wheel. The fixed seat is placed on the slide block so that the slide block is located between the fixed seat and the connecting seat. The bottom end of the adjusting member is riveted to one end of the slide block. The adjusting member passes through an adjusting hole on the connecting seat and is screwed to the adjusting hole. The bottom end of the eccentric wheel is riveted to the fixed seat. The eccentric wheel passes through the other end of the slide block and is placed in the first oblong hole of the connecting seat, and the eccentric wheel is movably engaged with the first oblong hole.
[0010] As a further embodiment, the top of the adjusting member is provided with a first driving part.
[0011] As a further embodiment, the eccentric wheel includes an integrally formed rotating shaft, an eccentric part, and a second driving part disposed on the top surface of the eccentric part. The rotating shaft is riveted to the fixed seat, and the eccentric part is placed in the first waist-shaped hole and movably engages with the first waist-shaped hole.
[0012] As a further solution, a second oblong hole is provided at the other end of the slide, and the rotating shaft is movably engaged with the second oblong hole.
[0013] As a further solution, the fixing base is provided with fixing holes, and both ends of the fixing base are integrally formed with positioning hooks.
[0014] As a further embodiment, the rotating mechanism also includes a decorative cover that covers the connecting seat and seals the through hole.
[0015] This utility model also provides a hinge, including the above-mentioned rotating mechanism. The hinge further includes a hinge cup, a hinge arm, and a damping mechanism. One end of the hinge arm is rotatably connected to the hinge cup, and the other end of the hinge arm is fixedly connected to a connecting seat. The damping mechanism is installed inside the hinge cup and is used to provide damping force when the hinge arm rotates relative to the hinge cup.
[0016] The beneficial effects of this utility model are as follows: This utility model uses two limiting plates and two bushings integrally formed with the connecting seat, and the other end of the two bushings forms a limiting groove between the two limiting plates. The hinge plates on both sides of the slide are hinged to the limiting grooves on both sides by pins, thereby limiting the hinge plates on both sides of the slide. This improves the load-bearing capacity when the hinge plates on both sides of the slide are rotatably connected to the pins, and prevents the pins from disengaging from the hinge plates when the connecting seat is under force, thereby improving the stability of the rotatable connection between the slide and the connecting seat.

Detailed Implementation
[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0020] It should be noted that, as shown in the attached document... Figure 9 As shown in the following description, the up-down direction is perpendicular to the horizontal plane and perpendicular to the sliding direction of the slide block 2; the left-right direction is parallel to the horizontal plane and perpendicular to the sliding direction of the slide block 2; the front-back direction is parallel to the horizontal plane and also parallel to the sliding direction of the slide block 2.
[0021] Example 1 As attached Figure 7 As shown, the present invention provides a rotating mechanism including a slide 2 and a connecting seat 3. The connecting seat 3 is used to connect with a hinge arm 9. The connecting seat 3 has a receiving groove 31. The bottom of the receiving groove 31 is integrally formed with two limiting plates 32 and two bushings 33. The two limiting plates 32 are spaced apart, and the two bushings 33 are also spaced apart. The two ends of the two limiting plates 32 extend to the two groove walls of the receiving groove 31, thereby forming an integral structure between the two limiting plates 32 and the groove walls of the receiving groove 31, enhancing the load-bearing capacity of the two limiting plates 32.
[0022] As attached Figure 5-7 As shown, the axial directions of the two bushings 33 are perpendicular to the length direction of the limiting plate 32. One end of each bushing 33 extends to the other two groove walls of the receiving groove 31, that is, one end of each bushing 33 is integrally formed with the other two groove walls of the receiving groove 31, thereby enhancing the load-bearing capacity of the two bushings 33. The other ends of each bushing 33 are close to the two limiting plates 32, and the other ends of each bushing 33 form limiting grooves 34 between the two limiting plates 32. The slide 2 is placed in the receiving groove 31, and hinge plates 21 are integrally formed on both sides of the slide 2. Both hinge plates 21 are hinged to the limiting grooves 34 on both sides by pins 1. The limiting plates 32 and bushings 33 limit the hinge plates 21.
[0023] This utility model uses two limiting plates 32 and two bushings 33 integrally formed with the connecting seat 3, and the other end of the two bushings 33 respectively forms a limiting groove 34 between the two limiting plates 32. The hinge plates 21 on both sides of the slide 2 are hinged to the limiting grooves 34 on both sides by pins, thereby limiting the hinge plates 21 on both sides of the slide 2. This improves the load-bearing capacity when the hinge plates 21 on both sides of the slide 2 are rotatably connected with the pins 1, and prevents the pins 1 from disengaging from the hinge plates when the connecting seat 3 is under force, thereby improving the stability of the rotatable connection between the slide 2 and the connecting seat 3.
[0024] Further details are attached. Figure 7 As shown, the two limiting plates 32 and the two bushings 33 are mirror-symmetrical about the center line of the receiving groove 31, ensuring that the force on both sides of the slide block 2 is uniform.
[0025] In a preferred embodiment, both hinge plates 21 are perpendicular to the slide block 2. Two pins 1 are provided, which pass sequentially through the through holes 35 on both sides of the receiving groove 31, the bushing 33, and the hinge holes 22 on the hinge plate 21, and abut against the two limiting plates 32 respectively. Through the cooperation of the side walls of the receiving groove 31, the bushing 33, and the limiting plates 32, the two pins 1 are limited in the radial and axial directions respectively.
[0026] Alternatively, in some embodiments, the pin 1 passes through the through hole 35, bushing 33, hinge hole 22 on the hinge plate 21, and limiting plate 32 on one side of the receiving groove 31, and also passes through the limiting plate 32, hinge hole 22 on the hinge plate 21, bushing 33, and through hole 35 on the other side of the receiving groove 31. That is, the hinge plates 21 on both sides of the slide 2 are hinged in the limiting grooves 34 on both sides by the same pin 1. Therefore, the pin 1 needs to pass through two limiting plates 32, which is a feasible embodiment.
[0027] In some embodiments, as shown in the appendix Figure 3-5As shown, the rotating mechanism also includes a fixed base 4, an adjusting component 5, and an eccentric wheel 6. The fixed base 4 is placed on the slide 2 so that the slide 2 is located between the fixed base 4 and the connecting base 3. Specifically, the fixed base 4 has a fixing hole 41, and screws are used to pass through the fixing hole 41 to fix the fixed base 4 to the inner wall of the cabinet 10. The bottom end of the adjusting component 5 is riveted to one end of the slide 2, so that the adjusting component 5 can rotate along the riveting point. In addition, the adjusting component 5 passes through the adjusting hole 36 on the connecting base 3, and the adjusting component 5 is screwed to the adjusting hole 36. The slide 2 and the connecting base 3 are connected as one unit by the adjusting component 5, and the included angle formed between the connecting base 3 and the slide 2 can be adjusted by the screwing of the adjusting component 5 to the adjusting hole 36, thereby adjusting the left and right offset distance of the hinge arm 9. Specifically, the top of the adjusting member 5 is provided with a first driving part 51. The first driving part 51 can be a slotted or Phillips head that is compatible with a screwdriver, or an internal hexagonal head that is compatible with a hex wrench. A screwdriver or a hex wrench or other tools are inserted into the slotted or Phillips head or internal hexagonal head to turn the first driving part 51 to apply force, thereby causing the adjusting member 5 to rotate relative to the adjusting hole 36.
[0028] Furthermore, the bottom end of the eccentric wheel 6 is riveted to the fixed seat 4, and the eccentric wheel 6 passes through the other end of the slide 2 and is placed in the first oblong hole 37 of the connecting seat 3, with the eccentric wheel 6 and the first oblong hole 37 in a movable fit. Specifically, the length direction of the first oblong hole 37 is perpendicular to the sliding direction of the slide 2. Through the movable fit between the eccentric wheel 6 and the first oblong hole 37, the connecting seat 3 is driven to move in the front-back direction, thereby adjusting the front-back offset distance of the hinge arm 9.
[0029] For details, see attached. Figure 5 As shown, the eccentric wheel 6 includes an integrally formed rotating shaft portion 61, an eccentric portion 62, and a second drive portion 63 disposed on the top surface of the eccentric portion 62. The rotating shaft portion 61 is riveted to the fixed seat 4, and the eccentric portion 62 is placed in the first oblong hole 37 and movably engages with the first oblong hole 37. The diameter of the eccentric portion 62 is larger than the diameter of the rotating shaft portion 61. The rotating shaft portion 61 is a circular wheel, riveted to the fixed seat 4, allowing the eccentric wheel 6 to rotate relative to the fixed seat 4. The eccentric portion 62 can be a circular wheel or a cam body. The centerline of the eccentric portion 62 is offset from the rotation axis of the rotating shaft portion 61, but both axes are parallel to the left-right direction. The second drive portion 63 can be referenced from the first drive portion 51. With the movable engagement of the eccentric portion 62 and the first oblong hole 37, the connecting seat 3 is pushed to move in the front-back direction, thereby adjusting the front-back offset distance of the hinge arm 9.
[0030] The specific adjustment principle is as follows: The second drive unit 63 can be turned. Since the center of the eccentric part 62 is not at the rotation point, the distance between the farthest position of the eccentric part 62 on the outer edge and the rotation point is not equal to the distance between the closest position of the eccentric part 62 on the outer edge and the rotation point. Therefore, when the action is applied to the farthest position and gradually moved to the closest position, a displacement variable will be generated, which is the adjustable displacement variable of the eccentric part 62. When the eccentric part 62 rotates, since the fixed seat 4 that interacts with the rotating shaft part 61 is fixed, the position of the rotation point remains unchanged. When the eccentric part 62 is in movable engagement with the first waist-shaped hole 37, it causes the connecting seat 3 to slide in the sliding direction of the slide 2, that is, in the front-back direction, thereby realizing the linear sliding adjustment of the hinge arm 9 in the front-back direction, and thus achieving the purpose of adjusting the front-back offset distance of the hinge arm 9.
[0031] Furthermore, as attached Figure 4 As shown, a second oblong hole 23 is provided at the other end of the slide 2. The rotating shaft 61 is movably engaged with the second oblong hole 23. The length direction of the second oblong hole 23 is parallel to the sliding direction of the slide 2. Since the slide 2 also slides along with the connecting seat 3 in the sliding direction of the slide 2 (i.e., the front-to-back direction) when the eccentric part 62 is movably engaged with the first oblong hole 37, and the rotating shaft 61 is positioned at a single point, the second oblong hole 23 is required to engage with the rotating shaft 61.
[0032] In actual installation, to ensure that door 101 and the outer wall of cabinet 10 remain on the same plane when the door is open, a rectangular strip is usually added to the inner wall of cabinet 10, with the length of the strip running vertically. (See attached image.) Figure 2 , 5 As shown, positioning hooks 42 are integrally formed at both ends of the fixing base 4. The positioning hooks 42 make it easy to clamp the fixing base 4 onto the strip, which facilitates installation.
[0033] In some embodiments, as shown in the appendix Figure 1-3 As shown, the rotating mechanism also includes a decorative cover 7, which covers the connecting seat 3 and seals the through hole 35. The purpose of sealing the through hole 35 is to prevent the pin 1 from falling out of the through hole 35, so that the pin 1 can be confined in the through hole 35 when the connecting seat 3 is under force, thereby improving the stability of the rotating connection between the slide 2 and the connecting seat 3.
[0034] Example 2 As attached Figure 8-9As shown, this embodiment provides a hinge, including the aforementioned rotating mechanism. The hinge also includes a hinge cup 8, a hinge arm 9, and a damping mechanism 81. One end of the hinge arm 9 is rotatably connected to the hinge cup 8, and the other end of the hinge arm 9 is fixedly connected to the connecting seat 3, preferably by welding. The damping mechanism 81 is installed inside the hinge cup 8 and provides damping force when the hinge arm 9 rotates relative to the hinge cup 8. The hinge cup 8 can be used to connect and fix to the door body 101. By slowing down the relative rotation speed between the hinge arm 9 and the hinge cup 8, the damping mechanism 81 can reduce the direct impact and friction between mechanical parts, reduce the wear rate, and thus extend the service life of the hinge.
[0035] At this time, by adjusting one of the above-mentioned rotating mechanisms, the door 101 is aligned with the cabinet 10 in the left-right direction, and the gap between the door 101 and the cabinet 10 is adjusted in the front-back direction.
[0036] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
