Description

Technical Field

[0001] This utility model relates to the field of dining table technology, and more specifically, to a scratch-resistant dining table. Background Technology

[0002] Many existing table height adjustment mechanisms often rely on traditional manual knobs or lever structures. These designs are prone to inaccurate adjustments during use and require considerable force. Users may need to operate repeatedly to achieve the desired height, making the operation cumbersome and unintuitive. Some existing table height adjustment mechanisms also fail to provide smooth and uniform height adjustment. During the adjustment process, the tabletop may wobble or tilt, causing inconvenience to users, especially in situations where quick and stable tabletop height adjustments are required, often resulting in user discomfort.

[0003] Most scratch-resistant dining tables on the market still use relatively traditional fixing methods, such as screws and slots. These fixing methods are usually quite complicated and require tools or professionals to install and disassemble. In actual use, users often have to spend a lot of time and energy during assembly or disassembly, which affects the convenience of using the furniture. The connection structure between the dining table and the base is mostly quite strong and complex, which makes disassembly work extremely difficult when it is necessary to move, adjust or clean it. Especially in some small spaces, the connection between the dining table and the base is not easy to separate quickly, which can easily cause extra space waste or inconvenience in operation. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a scratch-resistant dining table to solve the technical problems mentioned in the background art, such as the inconvenience of height adjustment and the inconvenience of installation and disassembly between the dining table and the base frame.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a scratch-resistant dining table, comprising a tabletop, a height adjustment mechanism, a mounting and snapping mechanism, and a snapping auxiliary mechanism. The height adjustment mechanism includes an anti-scratch plate, a bottom support plate, a top support plate, a hinge frame, and a hydraulic cylinder. The anti-scratch plate is installed at the top end of the tabletop. The bottom end of the top support plate is connected to the bottom end of the tabletop through the mounting and snapping mechanism. The hinge frame is installed between the bottom support plate and the top support plate. The two ends of the hydraulic cylinder are rotatably connected to the hinge frame and the bottom support plate. The bottom end of the bottom support plate is supported by a contact surface. The mounting and snapping mechanism includes a snap-fit ​​tube, a snap-fit ​​rod, an annular groove, an embedded plate, a turntable, and a driving plate. The annular groove is located on the side wall of the snap-fit ​​rod, which can extend into the snap-fit ​​tube. The turntable is rotatably mounted inside the side wall of the snap-fit ​​tube. The driving plate is mounted on the outer end face of the turntable. The embedded plate is slidably mounted on the turntable. The rotation of the turntable causes the embedded plate to extend into or move away from the annular groove.

[0008] The present invention is further configured such that the snap-fit ​​auxiliary mechanism includes a bottom fixing ring, a spring support pin, a rotating ring, a threaded ring, and a clamping ring. The rotating ring is rotatably mounted on the outer wall of the snap-fit ​​tube, and the top end of the rotating ring is fixedly connected to the driving plate. The bottom fixing ring is fixedly mounted on the bottom end of the outer wall of the snap-fit ​​tube. Multiple sets of spring support pins are mounted on the bottom fixing ring, and the other end of the spring support pins pushes against the bottom end of the rotating ring, so that the rotating ring and the driving plate stably drive the turntable to rotate. The threaded ring is threadedly connected to the outer wall of the snap-fit ​​tube, and the clamping ring is mounted on the bottom end of the threaded ring. The clamping ring presses against the top end of the driving plate, so that the driving plate and the turntable are fixed in the rotation direction.

[0009] The present invention is further configured such that the hinged frames are arranged in pairs, and a linkage rod is installed between the two sets of hinged frames. The linkage rod makes the desktop lifting more uniform and stable, thereby improving the comfort and safety of use.

[0010] The present invention is further configured such that an installation plate is installed on one side of the top support plate and a bottom clamp is installed at the bottom end of the table. The design of the bottom clamp and the installation plate not only enhances the stability of the structure, but also ensures that the connection between the locking rod and the locking tube is simpler and more stable, reducing the structural instability or damage that may be caused by poor connection.

[0011] The present invention is further configured such that a connecting plate is installed at the bottom end of the side wall of the card tube, and the connecting plate is fixedly installed on one end face of the bottom clamp. By fixing the card tube to the end face of the bottom clamp, the connecting plate improves the tightness of the overall structure and enhances its durability.

[0012] This invention is further configured such that one end of the snap-fit ​​rod can pass through the bottom clamp and the mounting plate, and engages with the snap-fit ​​tube for quick snap-fit ​​connection, making the connection between various components simpler, stronger, and more reliable. In particular, the telescopic design of the snap-fit ​​rod allows for quick installation and disassembly.

[0013] The present invention is further configured such that a bottom guide groove is provided at the top end of the turntable, and the bottom end of the embedded plate is slidably guided in cooperation with the bottom guide groove.

[0014] The present invention is further configured such that a top guide groove is provided inside the side wall of the clamping tube, and the top end of the embedded plate is slidably guided in cooperation with the top guide groove. The design of the bottom guide groove and the top guide groove of the turntable in cooperation with the embedded plate not only ensures the sliding stability of the embedded plate, but also improves the accuracy of the clamping process.

[0029] Please see Figures 1-5The scratch-resistant dining table includes a tabletop 1, a height adjustment mechanism, a mounting clip mechanism, and a clip auxiliary mechanism. The height adjustment mechanism includes a scratch-resistant plate 2, a bottom support plate 3, a top support plate 4, a hinge frame 5, and a hydraulic cylinder 6. The scratch-resistant plate 2 is installed at the top end of the tabletop 1. The bottom end of the top support plate 4 is connected to the bottom end of the tabletop 1 via the mounting clip mechanism. The hinge frame 5 is fitted between the bottom support plate 3 and the top support plate 4. The two ends of the hydraulic cylinder 6 are rotatably connected to the hinge frame 5 and the bottom support plate 3. The bottom of the bottom support plate 3... The end and contact surface are supported and the mounting and snapping mechanism includes a snap-fit ​​tube 7, a snap-fit ​​rod 8, an annular groove 9, an embedded plate 10, a turntable 11, and a driving plate 12. The annular groove 9 is set on the side wall of the snap-fit ​​rod 8, and the snap-fit ​​rod 8 can extend into the snap-fit ​​tube 7. The turntable 11 is rotatably mounted inside the side wall of the snap-fit ​​tube 7. The driving plate 12 is mounted on the outer end face of the turntable 11. The embedded plate 10 is slidably mounted on the turntable 11. The rotation of the turntable 11 causes the embedded plate 10 to extend into or away from the annular groove 9.

[0030] In this embodiment, the hinged frame 5 is installed between the bottom support plate 3 and the top support plate 4, designed as a pair. A linkage rod 18 is installed between the two sets of hinged frames 5 to ensure synchronous lifting on both sides. The hinged frame 5 adopts a scissor-type structure design, which can be extended or retracted under the action of the hydraulic cylinder 6, thereby realizing the change of height. The two ends of the hydraulic cylinder 6 are respectively rotatably connected to the hinged frame 5 and the bottom support plate 3. When the hydraulic cylinder 6 extends, it pushes the hinged frame 5 to extend, and the top support plate 4 moves upward to increase the height of the table. When the hydraulic cylinder 6 retracts, the hinged frame 5 retracts, and the top support plate 4 descends to reduce the height of the table. A snap-fit ​​mechanism is installed to connect the top support plate 4 and the table 1 and to provide convenient disassembly and assembly. The drive plate 12 is installed on the outer end face of the turntable 11 to facilitate the operation of the turntable 11. When it is necessary to connect the top support plate 4 and the table 1, the snap-fit ​​rod 8 is first passed through the bottom clamp 20 and the mounting plate 19 and inserted into the snap-fit ​​tube 7. At this time, the turntable 11 is in a position that keeps the embedded plate 10 away from the annular groove 9. Then, rotating the drive plate 12 causes the turntable 11 to rotate. The rotation of the turntable 11 is guided by the bottom guide groove 22 and the top guide groove 23, causing the embedded plate 10 to move horizontally and extend into the annular groove 9 on the side wall of the snap-fit ​​rod 8, forming a snap-fit ​​lock and completing the firm connection between the top support plate 4 and the tabletop 1. Reverse rotation causes the drive plate 12 to rotate, and the turntable 11 rotates, causing the embedded plate 10 to exit from the annular groove 9, releasing the snap-fit ​​lock. Then the snap-fit ​​rod 8 can be pulled out to separate the top support plate 4 from the tabletop 1, making the disassembly and assembly of the tabletop 1 simple and quick, and convenient for transportation and storage.

[0031] The locking auxiliary mechanism includes a bottom fixing ring 13, a spring support pin 14, a rotating ring 15, a threaded ring 16, and a clamping ring 17. The rotating ring 15 is rotatably mounted on the outer wall of the locking tube 7, and the top end of the rotating ring 15 is fixedly connected to the driving plate 12. The bottom fixing ring 13 is fixedly mounted on the bottom end of the outer wall of the locking tube 7. Multiple sets of spring support pins are mounted on the bottom fixing ring 13, and the other end of the spring support pins pushes against the bottom end of the rotating ring 15, so that the rotating ring 15 and the driving plate 12 stably drive the turntable 11 to rotate. The threaded ring 16 is threadedly connected to the outer wall of the locking tube 7. The clamping ring 17 is mounted on the bottom end of the threaded ring 16 and presses against the top end of the driving plate 12, so that the driving plate 12 and the turntable 11 are fixed in the rotation direction.

[0032] In this embodiment, multiple sets of spring-loaded pins are installed on the bottom fixing ring 13. The other end of the spring-loaded pins pushes against the bottom end of the rotating ring 15. The spring-loaded pins can provide a uniform pushing force to the rotating ring 15, so that the rotating ring 15 and the driving plate 12 can stably drive the turntable 11 to rotate, eliminating the shaking or instability that may occur during rotation. When the turntable 11 rotates to the position where the embedded plate 10 extends into the annular groove 9, the threaded ring 16 is tightened, and the clamping ring 17 will press against the top end of the driving plate 12, so that the driving plate 12 and the turntable 11 are fixed in the rotation direction, preventing accidental rotation from causing jamming and unlocking.

[0033] Please see Figures 1-5 As a supplementary embodiment of the scratch-resistant dining table to the height adjustment mechanism, the mounting snap-fit ​​mechanism, and the snap-fit ​​auxiliary mechanism: the hinge frame 5 is set in pairs, and a linkage rod 18 is installed between the two sets of hinge frame 5. A mounting plate 19 is installed on one side of the top support plate 4. A bottom clamp 20 is installed at the bottom end of the tabletop 1. A connecting plate 21 is installed at the bottom end of the side wall of the snap-fit ​​tube 7, and the connecting plate 21 is fixedly installed on one end face of the bottom clamp 20. One end of the snap-fit ​​rod 8 can pass through the bottom clamp 20 and the mounting plate 19, and is quickly snapped in conjunction with the snap-fit ​​tube 7. A bottom guide groove 22 is opened at the top end of the turntable 11. The bottom end of the embedded plate 10 is slidably guided in conjunction with the bottom guide groove 22. A top guide groove 23 is opened inside the side wall of the snap-fit ​​tube 7, and the top end of the embedded plate 10 is slidably guided in conjunction with the top guide groove 23.

[0034] More specifically, the user activates the hydraulic cylinder 6, which drives the hinge frame 5, top support plate 4, and bottom support plate 3 to move, thereby adjusting the table height. During the adjustment process, the turntable 11 with the snap-fit ​​mechanism rotates to drive the embedded plate 10, which extends into or away from the annular groove 9, ensuring a stable connection between the table and the base. The rotating ring 15, spring pin, and driving plate 12 further ensure that the turntable 11 remains stable during the adjustment process. When the table is adjusted to the required height, the threaded ring 16 and the clamping ring 17 apply pressure to the driving plate 12 to ensure a firm connection between the tabletop 1 and the base, preventing loosening during use.

[0035] In summary, during the use or operation of the overall equipment: when the height adjustment mechanism is required, the hinged frame 5 is installed between the bottom support plate 3 and the top support plate 4, designed as a pair. A linkage rod 18 is installed between the two sets of hinged frames 5 to ensure synchronous lifting on both sides. The hinged frame 5 adopts a scissor-type structure design, which can be extended or retracted under the action of the hydraulic cylinder 6, thereby realizing the change of height. The two ends of the hydraulic cylinder 6 are respectively rotatably connected to the hinged frame 5 and the bottom support plate 3. When the hydraulic cylinder 6 extends, it pushes the hinged frame 5 to extend, and the top support plate 4 moves upward, raising the table height. When the hydraulic cylinder 6 retracts, the hinged frame 5 retracts, and the top support plate 4 descends, lowering the table height.

[0036] When the snap-fit ​​mechanism is installed, it connects the top support plate 4 and the tabletop 1, providing convenient assembly and disassembly. The drive plate 12 is installed on the outer end face of the turntable 11 for easy operation. When connecting the top support plate 4 and the tabletop 1, the snap-fit ​​rod 8 is first passed through the bottom clamp 20 and the mounting plate 19 and inserted into the snap-fit ​​tube 7. At this time, the turntable 11 is positioned so that the embedded plate 10 is away from the annular groove 9. Then, the drive plate 12 is rotated, causing the turntable 11 to rotate. The rotation of the turntable 11 is guided by the bottom guide groove 22 and the top guide groove 23, causing the embedded plate 10 to move horizontally and extend into the annular groove 9 on the side wall of the snap-fit ​​rod 8, forming a snap-fit ​​lock and completing the firm connection between the top support plate 4 and the tabletop 1. The drive plate 12 is rotated in the opposite direction, and the turntable 11 rotates, causing the embedded plate 10 to exit from the annular groove 9, releasing the snap-fit ​​lock. Then, the snap-fit ​​rod 8 can be pulled out to separate the top support plate 4 and the tabletop 1, making the assembly and disassembly of the tabletop 1 simple and quick, and convenient for transportation and storage.

[0037] When the locking auxiliary mechanism is in operation, multiple sets of spring-loaded pins are installed on the bottom fixing ring 13. The other end of the spring-loaded pins pushes against the bottom end of the rotating ring 15. The spring-loaded pins can provide a uniform pushing force to the rotating ring 15, so that the rotating ring 15 and the driving plate 12 can stably drive the turntable 11 to rotate, eliminating the shaking or instability that may occur during rotation. When the turntable 11 rotates to the position where the embedded plate 10 extends into the annular groove 9, the threaded ring 16 is tightened, and the clamping ring 17 will press against the top end of the driving plate 12, fixing the driving plate 12 and the turntable 11 in the rotation direction and preventing accidental rotation from causing locking and unlocking.

[0038] The user activates hydraulic cylinder 6, which drives the hinge frame 5, top support plate 4, and bottom support plate 3 to move, thereby adjusting the table height. During the adjustment process, the turntable 11 with the snap-fit ​​mechanism rotates to drive the embedded plate 10, which extends into or away from the annular groove 9, ensuring a stable connection between the table and the base. The rotating ring 15, spring pin, and driving plate 12 further ensure that the turntable 11 remains stable during the adjustment process. When the table is adjusted to the required height, the threaded ring 16 and the clamping ring 17 apply pressure to the driving plate 12 to ensure a firm connection between the tabletop 1 and the base, preventing loosening during use.

[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
