Description

Technical Field

[0001] This invention relates to the technical field of cabinet door gas spring fittings, specifically, a two-way buffer device and a cabinet. Background Technology

[0002] A gas strut is an accessory that provides support, cushioning, braking, height adjustment, and angle adjustment. Gas struts are widely used for connecting cabinet doors in cabinets, furniture, filing cabinets, bathroom vanities, and other cabinetry. Since the gas strut does not provide cushioning during its expansion when the cabinet door is opened, a cushioning cup hinge or cushioning mechanism is usually required. This mechanism connects to the gas strut for synergistic action. For example, Chinese patent document CN221779278U discloses a cushioning mechanism and cabinet, including a mounting base, a connector, and a lever. The mounting base is fixed to the cabinet door, thus connecting to it. One end of the mounting base has a first damping buffer. The connector can be connected to the cabinet body via a gas spring. One end of the connector can be hinged to the other end of the mounting base via a pin, allowing the connector to rotate relative to the mounting base. The other end of the connector has a second damping buffer. The lever is rotatably disposed inside the mounting base, meaning it can rotate relative to the mounting base and is located between the mounting base and the connector.

[0003] However, in the aforementioned buffer mechanism, since an internal lever is required for swinging, and the first and second damping buffers are arranged vertically, a height difference is formed in the squeezing part when the door is opened or closed. This directly results in the entire buffer mechanism being relatively thick, large in volume, and relatively expensive. Moreover, after being installed on the cabinet door, users are prone to bumping into the buffer mechanism when taking items out of the cabinet. Summary of the Invention

[0004] In order to overcome the defects of the prior art, the present invention provides a bidirectional buffer device and cabinet, which aims to solve the problems in the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is: a bidirectional buffer device, comprising: A base, wherein corresponding hinge seats are provided on both sides of the base; A gas spring connector is hinged between two hinged seats on both sides. One end of the gas spring connector is provided with a first pressure block and the other end is provided with a second pressure block. The first damping buffer is horizontally engaged between the base and the gas spring connector. When the gas spring connector is swung to one end, the first pressure block presses against the first damping buffer. The second damping buffer is horizontally snapped between the base and the gas spring connecting seat. The second damping buffer is arranged parallel to one side of the first damping buffer. When the gas spring connecting seat is swinging to the other end, the second pressure block squeezes the second damping buffer. An eccentric adjustment damping module is located on the base of the second damping buffer at the end away from the second pressure block. The eccentric adjustment damping module is used to adjust the extension length of the buffer shaft of the second damping buffer.

[0006] After implementing the above technical solution, the first damping buffer and the second damping buffer are arranged in parallel with each other. The first damping buffer and the second damping buffer are switched and squeezed by the swing of the gas strut connecting seat, thereby achieving the buffering effect of opening and closing the door. This makes the thickness of the entire structure thinner than the traditional structure, reducing the phenomenon of accidental collisions during use. Moreover, the structure is simpler and more convenient than the traditional one, greatly reducing the cost of use. At the same time, the eccentric adjustment damping module can adjust the damping effect of the second damping buffer, making it more convenient to use.

[0007] In the aforementioned bidirectional buffer device, a first slot and a second slot are provided between the two hinge seats on the base. A third slot and a fourth slot are provided on the outer wall of the gas strut connector. The third slot and the fourth slot are both arranged along the swing direction of the gas strut connector. The first slot and the third slot are vertically aligned, and the second slot and the fourth slot are vertically aligned. The first damping buffer is engaged in the first slot, and the second damping buffer is engaged in the second slot.

[0008] After implementing the above technical solution, the first damping buffer and the second damping buffer can be better engaged in the base, making the overall volume smaller. During the swinging process of the gas strut connector, the first damping buffer and the second damping buffer can also be limited by the third and fourth slots to prevent the first damping buffer and the second damping buffer from detaching from the base, making the overall structure more compact and stable.

[0009] In the aforementioned bidirectional buffer device, the first pressure block is located at one end of the third slot, and the second pressure block is located at the end of the fourth slot away from the first pressure block, so that the top view projections of the first pressure block and the second pressure block do not overlap.

[0010] After implementing the above technical solution, the gas support connecting seat can squeeze the corresponding damping buffer through the first and second pressure blocks during the swing process, thereby achieving a bidirectional buffering effect.

[0011] In the aforementioned bidirectional buffer device, a limiting boss is provided at the end of the first slot away from the first pressure block. A cavity communicating with the first slot is provided in the limiting boss, so that the buffer shaft of the first damping buffer is pressed against the limiting boss. The eccentric adjustment damping module is located at the end of the second slot away from the limiting boss, and the buffer shaft of the second damping buffer is pressed against the eccentric adjustment damping module.

[0012] After implementing the above technical solution, the limiting boss can better hold the first damping buffer in the first slot to prevent loosening, the structure is more compact, and the eccentric adjustment damping module can be used to adjust the damping stroke of the second damping buffer, making it more convenient to use.

[0013] In the aforementioned bidirectional buffer device, the eccentric adjustment damping module includes an eccentric wheel and a movable slider. The buffer shaft of the second damping buffer presses against the slider. The eccentric wheel is rotatably mounted on the base and is in contact with the slider.

[0014] After implementing the above technical solution, by rotating the eccentric wheel, the slider is pushed and moved, causing the slider to squeeze the second damping buffer, thereby adjusting the damping stroke of the second damping buffer, making the adjustment more convenient.

[0015] In the aforementioned bidirectional buffer device, the base is provided with a slide block, and the slide block is provided with a slider cavity with an open lower end. The slider cavity is connected to a second slot, and the slider is disposed in the slider cavity. The end of the slide block near the eccentric wheel is provided with a through hole.

[0016] After implementing the above technical solution, the slider moves within the slider cavity, preventing the slider from detaching, and the slider movement is more stable.

[0017] In the aforementioned bidirectional buffer device, the end face of the slider facing the eccentric wheel is a concave arc-shaped surface. Multiple raised first limiting ribs are provided on the surface of the arc-shaped surface, and multiple second limiting ribs are provided on the outer wall of the eccentric wheel. The second limiting ribs are engaged between two adjacent first limiting ribs.

[0018] After implementing the above technical solution, the contact surface between the eccentric wheel and the slider is an arc surface. When the slider is squeezed in the opposite direction by the second damping buffer, the slider also squeezes the eccentric wheel. Under the action of the first limit rib and the second limit rib, the accidental rotation of the eccentric wheel is prevented from causing the damping stroke of the second damping buffer to change, thereby improving the compactness of the structure and making it more stable in use.

[0019] In the aforementioned bidirectional buffer device, an eccentric wheel connection hole is provided on the base, and the eccentric wheel is threadedly connected to the eccentric wheel connection hole via a screw.

[0020] After implementing the above technical solution, the eccentric wheel can be rotatably mounted on the base, thereby facilitating the rotation of the eccentric wheel to adjust the position of the slider and realize the damping stroke adjustment of the second damping buffer.

[0021] In the aforementioned bidirectional buffer device, a cover is provided at the opening at the lower end of the slider cavity, a support rib is provided on the side of the cover facing the slider, a positioning post is also provided on the cover, a positioning groove is provided at the opening at the lower end of the slider cavity, and the positioning post is embedded in the positioning groove.

[0022] After implementing the above technical solution, the slider can be installed more stably in the slider cavity, and the structure is simpler and the assembly is more convenient.

[0023] In the aforementioned bidirectional buffer device, the gas support connecting seat is provided with a gas support connecting screw hole.

[0024] After implementing the above technical solution, it is convenient to connect the gas strut connector to the gas strut rod.

[0025] The present invention also discloses a cabinet, including the above-mentioned bidirectional buffer device, and a cabinet body, wherein a cabinet door is hinged to the upper end of the opening of the cabinet body; a gas strut is provided on one side of the inner wall of the cabinet body, the gas strut is provided with a gas strut body and a rod body, the gas strut body is hinged to the inner wall of the cabinet body, the end of the rod body is threadedly connected to the gas strut connecting seat, and the base is provided with a mounting hole, so that the base is fixed to the cabinet door by bolts passing through the mounting hole.

[0026] The beneficial effects of this invention are that a single bidirectional buffer device can achieve the buffering effect of opening and closing the door. Moreover, the thickness of the entire bidirectional buffer device is thinner and smaller than that of the traditional structure, and it occupies less space, reducing the occurrence of accidental collisions during use. Furthermore, the structure is simpler and more convenient than the traditional one, greatly reducing the cost of use. Attached Figure Description

[0038] The specific embodiments of the present invention 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 the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Combination Figures 1 to 10The bidirectional buffer device shown includes: a base 1, a gas spring connecting seat 4, a first damping buffer 2, a second damping buffer 3, and an eccentric adjustment damping module. The base 1 has corresponding hinge seats 11 on both sides. The gas spring connecting seat 4 is hinged between the two hinge seats 11. One end of the gas spring connecting seat 4 is provided with a first pressure block 40, and the other end is provided with a second pressure block 41. The first damping buffer 2 is horizontally engaged between the base 1 and the gas spring connecting seat 4. When the gas spring connecting seat 4 swings to one end, the first pressure block 40 presses against the first damping buffer 2. The second damping buffer 3 is horizontally engaged between the base 1 and the gas spring connecting seat 4. The second damping buffer 3 is parallel to one side of the first damping buffer 2. When the gas spring connecting seat 4 swings to the other end, the second pressure block 40 presses against the first damping buffer 2. 1. The second damping buffer 3 is compressed; the eccentric adjustment damping module is located on the base 1 at the end of the second damping buffer 3 away from the second pressure block 41. The eccentric adjustment damping module is used to adjust the extension length of the buffer shaft of the second damping buffer 3; in this embodiment, the first damping buffer 2 and the second damping buffer 3 are arranged parallel to each other. The compression of the first damping buffer 2 and the second damping buffer 3 can be switched by swinging the gas strut connecting seat 4, thereby achieving the buffering effect of opening and closing the door. This makes the thickness of the entire structure thinner than the traditional structure, reducing the phenomenon of accidental collisions during use. Moreover, the structure is simpler and more convenient than the traditional one, greatly reducing the cost of use. At the same time, the eccentric adjustment damping module can adjust the damping effect of the second damping buffer 3, making it more convenient to use.

[0040] It is worth noting that the first damping buffer 2 and the second damping buffer 3 in this embodiment are both existing technologies, and their structural principles will not be described in detail here.

[0041] In this embodiment, a first slot 12 and a second slot 14 are provided between the two hinge seats 11 on the base 1. Both the first slot 12 and the second slot 14 are strip-shaped slots that match the shape of the damping buffer. A third slot 43 and a fourth slot 44 are provided on the outer wall of the gas spring connecting seat 4. The length direction of the third slot 43 and the fourth slot 44 are both arranged along the swing direction of the gas spring connecting seat 4, so that the third slot 43 and the fourth slot 44 are arranged around the outer wall of the gas spring connecting seat 4. The first slot 12 and the third slot 43 are vertically aligned, and the second slot 14... Corresponding vertically to the fourth slot 44, the first damping buffer 2 is engaged in the first slot 12, and the second damping buffer 3 is engaged in the second slot 14. The first damping buffer 2 and the second damping buffer 3 can be better engaged in the base 1, making the overall volume smaller and the thickness thinner. During the swinging process of the gas strut connecting seat 4, the first damping buffer 2 and the second damping buffer 3 can also be limited by the third slot 43 and the fourth slot 44 to prevent the first damping buffer 2 and the second damping buffer 3 from detaching from the base 1, making the overall structure more compact and stable.

[0042] It is worth noting that in this embodiment, the first pressure block 40 is located at one end of the third slot 43, and the second pressure block 41 is located at the end of the fourth slot 44 away from the first pressure block 40, so that the top view projections of the first pressure block 40 and the second pressure block 41 do not coincide, that is, the top view projections of the first pressure block 40 and the second pressure block 41 are not on the same straight line; this allows the gas strut connecting seat 4 to squeeze the corresponding damping buffer through the first pressure block 40 and the second pressure block 41 during the swinging process, thereby achieving a bidirectional buffering effect. For example, see Figure 9 The swinging state of the gas spring connecting seat 4 during the door opening process is shown. The first pressure block 40 presses against the first damping buffer 2, so that when the cabinet door 9 is fully opened, it can stabilize the cabinet door 9 and prevent the cabinet door 9 from colliding with the cabinet body 8; see also Figure 10 The swinging state of the gas spring connecting seat 4 during the closing process is shown. The second pressure block 41 presses against the second damper 3, and the first pressure block 40 swings away from the first damper buffer 2, so that when the cabinet door 9 is close to the closed state, it plays a buffering role and prevents the cabinet door from colliding with the cabinet body 8.

[0043] In this embodiment, a limiting boss 13 is provided at the end of the first slot 12 away from the first pressure block 40. The limiting boss 13 is semi-circular and protrudes relative to the surface of the base 1. A cavity communicating with the first slot 12 is provided in the limiting boss 13, so that the buffer shaft of the first damping buffer 2 is pressed against the limiting boss 13. The eccentric adjustment damping module is located at the end of the second slot 14 away from the limiting boss 13, and the buffer shaft of the second damping buffer 3 is pressed against the eccentric adjustment damping module. The limiting boss 13 can better lock the first damping buffer 2 in the first slot 12 to prevent loosening, and the structure is more compact. The eccentric adjustment damping module can be used to adjust the damping stroke of the second damping buffer 3, making it more convenient to use.

[0044] Specifically, the eccentric adjustment damping module includes an eccentric wheel 6 and a movable slider 5. The buffer shaft of the second damping buffer 3 presses against the slider 5. The eccentric wheel 6 is rotatably mounted on the base 1 and is in contact with the slider 5. By rotating the eccentric wheel 6, the slider 5 is pressed and moved, causing the slider 5 to squeeze the second damping buffer 3, thereby adjusting the damping stroke of the second damping buffer 3, making adjustment more convenient.

[0045] More specifically, in this embodiment, the base 1 is provided with a slide 15, and the slide 15 is provided with a slider cavity 17 with an open lower end. The slider cavity 17 is connected to the second slot 14. The slider 5 is disposed in the slider cavity 17. The end of the slide 15 near the eccentric wheel 6 is provided with a through hole 16. The slider 5 moves in the slider cavity 17 to prevent the slider 5 from falling off, and the movement of the slider 5 is more stable.

[0046] Furthermore, in this embodiment, the end face of the slider 5 facing the eccentric wheel 6 is a concave arc-shaped surface 50. Multiple raised first limiting ribs 51 are provided on the surface of the arc-shaped surface 50, and multiple second limiting ribs 60 are provided on the outer wall of the eccentric wheel 6. The second limiting ribs 60 are engaged between two adjacent first limiting ribs 51. The contact surface between the eccentric wheel 6 and the slider 5 is an arc surface. When the slider 5 is pressed in the opposite direction by the second damping buffer 3, the slider 5 also presses the eccentric wheel 6. Under the action of the first limiting ribs 51 and the second limiting ribs 60, the eccentric wheel 6 is prevented from rotating accidentally, which would cause the damping stroke of the second damping buffer 3 to change, thereby improving the compactness of the structure and making it more stable in use.

[0047] It is worth noting that the base 1 in this embodiment is provided with an eccentric wheel connection hole 19, and the eccentric wheel 6 is threadedly connected to the eccentric wheel connection hole 19 by a screw; so that the eccentric wheel 6 can be rotatably mounted on the base 1, thereby facilitating the rotation of the eccentric wheel 6 to adjust the position of the slider 5 and realize the damping stroke adjustment of the second damping buffer 3.

[0048] More notably, a cover 7 is provided at the lower opening of the slider cavity 17, and a support rib 71 is provided on the side of the cover 7 facing the slider 5. A positioning post 70 is also provided on the cover 7, and a positioning groove 18 is provided at the lower opening of the slider cavity 17. The positioning post 70 is embedded in the positioning groove 18. This allows the slider 5 to be installed more stably in the slider cavity 17, and the structure is simpler and easier to assemble.

[0049] The gas spring connector 4 has a gas spring connecting screw hole 42, which facilitates connecting the gas spring connector 4 to the gas spring rod.

[0050] This embodiment also discloses a cabinet using the aforementioned bidirectional buffer device. The cabinet includes a cabinet body 8, with a cabinet door 9 hinged to the upper end of the opening of the cabinet body 8. A gas strut is provided on one side of the inner wall of the cabinet body 8. The gas strut has a gas strut body 80 and a rod 81. The gas strut body 80 is hinged to the inner wall of the cabinet body 8, and the end of the rod 81 is provided with an external thread. The rod 81 is threaded to the gas strut connecting screw hole 42 of the gas strut connecting seat 4, which is easy to assemble. The base 1 has a mounting hole 10, so that the base 1 is bolted into the mounting hole 10 and fixed to the cabinet door 9. This embodiment uses a single bidirectional buffer device to achieve the buffering effect of opening and closing the door. The installation of the cabinet is simpler, and the thickness of the entire bidirectional buffer device is thinner and smaller than the traditional structure, occupying less space and reducing the occurrence of accidental collisions during use. Moreover, the structure is simpler and more convenient than the traditional one, greatly reducing the cost of use.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention 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 the present invention, and these variations still fall within the protection scope of the present invention.
