Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a sliding 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 base 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 base tends to be thinner and smaller. Therefore, larger parts such as torsion springs and dampers are designed in the hinge cup.

[0004] The invention patent application with publication number CN 120061659 A specifically discloses a modular ultra-thin hinge chassis and system based on an integrated molding process. According to its disclosed technical content and accompanying drawings, it is achieved by hinged a second arm to one end of a movable plate. The angle between the second arm and the movable plate is adjusted using an adjusting screw, thereby adjusting the movement of the second arm along the Z-axis. Rotating the first adjusting member allows the movable plate to move relative to the base along a first direction, thereby causing the ultra-thin hinge arm assembly and hinge cup to also move along the first direction, i.e., along the X-axis. However, the movable plate's connection to the base relies solely on the first adjusting member and the adjusting screw. When adjusting the first adjusting member and the adjusting screw, the movable plate becomes unstable in the Z-axis direction, easily becoming loose, leading to door wobbling during adjustment. Utility Model Content

[0005] In order to overcome the defects of the existing technology, this utility model provides a sliding mechanism and hinge to solve the problem of door shaking.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a sliding mechanism, including a fixed seat, a sliding seat and a connecting seat. Both sides of the sliding seat are fixed with hinge plates, one end of each hinge plate is hinged to the connecting seat, and both hinge plates are provided with notches. Both sides of the fixed seat are fixed with limit hooks, and the limit hooks on both sides are respectively close to the hinge plates on both sides, and the hook parts of the limit hooks on both sides are respectively placed in the notches on both sides.

[0007] As a further option, the hook portion of the limiting hook can slide within the notch along the sliding direction of the slide block.

[0008] As a further embodiment, each of the limiting hooks is provided with limiting posts on both sides, the limiting posts are connected and fixed to the fixing base, and each limiting post is located on the outside of the hinge plate and close to the hinge plate.

[0009] As a further option, the cross-section of the limiting post is circular or elliptical.

[0010] As a further embodiment, the sliding mechanism also includes an adjusting member and an eccentric wheel. The bottom end of the adjusting member is riveted to one end of the slide block. The adjusting member passes through the 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.

[0011] As a further embodiment, the top of the adjusting member is provided with a first driving part.

[0012] 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.

[0013] 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.

[0014] As a further embodiment, the connecting seat is provided with a receiving groove, and the fixed seat and the sliding seat are both placed in the receiving groove, with the sliding seat located between the fixed seat and the connecting seat. The bottom of the receiving groove is integrally formed with two limiting plates, the length direction of the two limiting plates is parallel to the sliding direction of the sliding seat, and the two limiting plates are respectively located on the inner side of the two hinge plates and are respectively close to the hinge plates.

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: By fixing limit hooks on both sides of the fixed base, the limit hooks on both sides limit the hinge plates on both sides in the vertical direction, thereby ensuring that the slide and connecting seat maintain linear movement when sliding in the front-back direction. Furthermore, the hook parts of the limit hooks on both sides are respectively placed in the notches on both sides, thereby restricting the swaying of the slide and connecting seat in the left-right direction and preventing the door from shaking.

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 7-8 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 1-3As shown, the present invention provides a sliding mechanism including a fixed base 1, a slide 2, and a connecting base 3. The connecting base 3 is used to connect and fix with the hinge arm 7. The fixed base 1 can be provided with fixing holes, and screws are passed through the fixing holes to fix the fixed base 1 to the inner wall of the cabinet 8 so that it remains stationary. Hinges 21 are fixed to both sides of the slide 2. Specifically, the hinges 21 can be fixed to both sides of the slide 2 by welding or integral molding, and the hinges 21 are perpendicular to the slide 2. One end of each hinge 21 is hinged to the connecting base 3. Specifically, a pin can be used to hinge them, so that the slide 2 and the connecting base 3 are rotatably connected and form an integral unit. At the same time, notches 211 are provided on both sides of the hinge 21 at the edge of the hinge 21.

[0022] As attached Figure 2 As shown, limit hooks 11 are fixed on both sides of the fixed base 1. Specifically, the limit hooks 11 are fixed to both sides of the fixed base 1 by welding or integral molding, and the limit hooks 11 are perpendicular to the fixed base 1. The limit hooks 11 on both sides are close to the hinge plates 21 on both sides, so that the limit hooks 11 on both sides limit the hinge plates 21 on both sides in the vertical direction, thereby keeping the slide 2 and the connecting seat 3 in a straight line when sliding in the front-back direction. Moreover, the hook parts 12 of the limit hooks 11 on both sides are placed in the notches 211 on both sides, and the hook parts 12 of the limit hooks 11 are close to the hinge plates 21, thereby limiting the swaying of the slide 2 and the connecting seat 3 in the left-right direction, thereby preventing the door body 81 from shaking.

[0023] The present invention solves this problem by fixing limit hooks 11 on both sides of the fixed base 1, so that the limit hooks 11 on both sides limit the hinge plates 21 on both sides in the vertical direction, thereby ensuring that the slide 2 and the connecting base 3 maintain linear movement when sliding in the front-back direction. Furthermore, the hook parts 12 of the limit hooks 11 on both sides are respectively placed in the notches 211 on both sides, thereby limiting the swaying of the slide 2 and the connecting base 3 in the left-right direction, thus preventing the door 81 from shaking.

[0024] Furthermore, compared to existing technologies, the technical solution of this utility model uses fewer parts and has a simpler structure.

[0025] Further details are attached. Figure 2 As shown, along the sliding direction of the slide block 2, the hook part 12 of the limiting hook 11 can slide within the notch 211. That is, the notch 211 provides sufficient redundant space for the hook part 12 of the limiting hook 11 in the front-back direction, so as not to restrict the sliding of the slide block 2 in the front-back direction.

[0026] In some embodiments, as shown in the appendix Figure 2 , 5As shown, each limiting hook 11 has a limiting post 13 on both sides. The limiting post 13 is connected and fixed to the fixed base 1, and each limiting post 13 is located on the outside of the hinge plate 21 and close to the hinge plate 21. The limiting post 13 plays a limiting and guiding role for the hinge plate 21, that is, the slide 2, which reduces the swaying of the slide 2 in the vertical direction and further ensures that the slide 2 maintains linear movement when sliding in the front-back direction. Specifically, the cross-section of the limiting post 13 is circular or elliptical, which can reduce the resistance between the slide 2 and the limiting post 13 when sliding.

[0027] As attached Figure 3 As shown, the sliding mechanism also includes an adjusting member 4 and an eccentric wheel 5. The bottom end of the adjusting member 4 is riveted to one end of the slide block 2, allowing the adjusting member 4 to rotate along the riveted joint. Furthermore, the adjusting member 4 passes through the adjusting hole 33 on the connecting seat 3, and the adjusting member 4 is screwed into the adjusting hole 33. The slide block 2 and the connecting seat 3 are connected as a whole by the adjusting member 4, and the angle formed between the connecting seat 3 and the slide block 2 can be adjusted by screwing the adjusting member 4 into the adjusting hole 33, thereby adjusting the left and right offset distance of the door body 81.

[0028] Specifically, the top of the adjusting member 4 is provided with a first driving part 41. The first driving part 41 can be a flat slot or a cross slot that is compatible with a screwdriver, or an internal hex slot that is compatible with a hex wrench. A screwdriver or a hex wrench or other tools are inserted into the flat slot, cross slot or internal hex slot, and the first driving part 41 is turned to apply force, thereby causing the adjusting member 4 to rotate relative to the adjusting hole 33.

[0029] Furthermore, as attached Figure 3 As shown, the bottom end of the eccentric wheel 5 is riveted to the fixed seat 1. The eccentric wheel 5 passes through the other end of the slide 2 and is placed in the first oblong hole 34 of the connecting seat 3, and the eccentric wheel 5 is movably engaged with the first oblong hole 34. Specifically, the length direction of the first oblong hole 34 is perpendicular to the sliding direction of the slide 2. Through the movable engagement of the eccentric wheel 5 with the first oblong hole 34, the connecting seat 3 is driven to move in the front-back direction, thereby adjusting the front-back offset distance of the door body 81.

[0030] For details, see attached. Figure 5As shown, the eccentric wheel 5 includes an integrally formed rotating shaft portion 51, an eccentric portion 52, and a second drive portion 53 disposed on the top surface of the eccentric portion 52. The rotating shaft portion 51 is riveted to the fixed seat 1, and the eccentric portion 52 is placed in the first waist-shaped hole 34 and movably engages with the first waist-shaped hole 34. The diameter of the eccentric portion 52 is larger than the diameter of the rotating shaft portion 51. The rotating shaft portion 51 is a circular wheel, riveted to the fixed seat 1, allowing the eccentric wheel 5 to rotate relative to the fixed seat 1. The eccentric portion 52 can be a circular wheel or a cam body. The centerline of the eccentric portion 52 is offset from the centerline of the rotation axis 51 of the rotating shaft portion 51, but both axes are parallel to the left-right direction. The second drive portion 53 can be referenced to the first drive portion 41. With the movable engagement of the eccentric portion 52 and the first waist-shaped hole 34, the connecting seat 3 is pushed to move in the front-back direction, thereby adjusting the front-back offset distance of the door body 81.

[0031] The specific adjustment principle is as follows: The second drive unit 53 can be turned. Since the center of the eccentric part 52 is not at the rotation point, the distance between the farthest position of the eccentric part 52 on the outer edge and the rotation point is not equal to the distance between the closest position of the eccentric part 52 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 52. When the eccentric part 52 rotates, since the fixed seat 1 that interacts with the rotating shaft part 51 is fixed, the position of the rotation point remains unchanged. When the eccentric part 52 is in movable engagement with the first waist-shaped hole 34, it causes the slide 2 and the connecting seat 3 to slide in the sliding direction of the slide 2, that is, in the front-back direction, thereby achieving the purpose of adjusting the front-back offset distance of the door body 81.

[0032] Furthermore, as attached Figure 2-3 As shown, a second oblong hole 22 is provided at the other end of the slide 2, and the rotating shaft 51 is movably engaged with the second oblong hole 22. The length direction of the second oblong hole 22 is parallel to the sliding direction of the slide 2. Since the slide 2 slides in the front-back direction along with the connecting seat 3 when the eccentric part 52 is movably engaged with the first oblong hole 34, while the rotating shaft 51 is positioned at a single point, the second oblong hole 22 is needed to engage with the rotating shaft 51.

[0033] As attached Figure 4 , 6As shown, the connecting seat 3 has a receiving groove 31, and both the fixed seat 1 and the slide 2 are placed in the receiving groove 31, with the slide 2 located between the fixed seat 1 and the connecting seat 3. The connecting seat 3 conceals the fixed seat 1 and the slide 2 within the receiving groove 31, making the overall design more streamlined. The bottom of the receiving groove 31 is integrally formed with two limiting plates 32. The length direction of the two limiting plates 32 is parallel to the sliding direction of the slide 2, and the two limiting plates 32 are located on the inner side of the two hinge plates 21 and are close to the hinge plates 21. The two limiting plates 32 also limit the hinge plates 21 on both sides in the vertical direction, thus ensuring that the slide 2 and the connecting seat 3 maintain linear movement when sliding in the front-back direction. Furthermore, it can be improved by sealing the notches 211 on both sides of the bottom of the receiving groove 31, reducing the gap between the bottom of the receiving groove 31 and the hook portion 12 of the limiting hook 11, further ensuring that the slide 2 maintains linear movement when sliding in the front-back direction.

[0034] Example 2 As attached Figure 7-8 As shown, this embodiment provides a hinge including the aforementioned sliding mechanism. The hinge also includes a hinge cup 6, a hinge arm 7, and a damping mechanism 61. One end of the hinge arm 7 is rotatably connected to the hinge cup 6, and the other end of the hinge arm 7 is fixedly connected to the connecting seat 3, preferably by welding. The damping mechanism 61 is installed inside the hinge cup 6 and provides damping force when the hinge arm 7 rotates relative to the hinge cup 6. The hinge cup 6 can be used to connect and fix to the door body 81. By slowing down the relative rotation speed between the hinge arm 7 and the hinge cup 6, the damping mechanism 61 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 sliding mechanisms mentioned above, the door 81 is aligned with the cabinet 8 in the left and right directions, and the gap between the door 81 and the cabinet 8 is adjusted in the front and back directions.

[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.
