Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a side table with a height-adjustable tabletop. Background Technology

[0002] A side table is a type of home furniture, typically placed next to a sofa or bed, serving as a small additional tabletop. Existing sofa side tables are usually small tables or cabinets with simple structures. Because the small table of a side table is usually fixed in place, and the cabinet itself is limited by its small size, and the height of the small table is difficult to adjust, its flexibility is relatively low. Utility Model Content

[0003] The purpose of this invention is to provide a side table with a height-adjustable tabletop to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a side table with a height-adjustable tabletop, comprising: Cabinet; Tabletop; The lifting column assembly includes a lifting component, a base, and two guide plates. The base is fixed inside the cabinet. The lower ends of the two guide plates are detachably connected to the base. The two guide plates face each other, and a guide groove extending vertically is formed between the two guide plates. The horizontal cross-section of the guide groove is elliptical. The lifting assembly includes a first plate, a second plate, a third plate, and several elastic components. The elastic components are sandwiched between the first plate and the third plate, and the second plate is distributed between the first plate and the third plate. The elastic components pass through the second plate. The first plate and the third plate are slidably connected inside the guide groove, and the second plate is detachably connected to the bottom surface of the table.

[0005] Preferably, when the first plate, the second plate, and the third plate are distributed sequentially along the short diameter of the horizontal cross section of the guide groove, the elastic component is in a compressed state, and the elastic component applies elastic force to the first plate and the second plate.

[0006] Preferably, when the first plate, the second plate, and the third plate are distributed sequentially along the long diameter of the horizontal cross-section of the guide groove, the elastic component is in a static state.

[0007] Preferably, both the first plate and the third plate include a first substrate. The first substrate includes a first surface and a second surface, both of which extend in a vertical direction. The first surface and the second plate are opposite to each other, and the second surface is opposite to the inner wall of the guide groove. The second surface is an arc surface.

[0008] Preferably, the first plate and the third plate further include a plurality of guide posts, the first surface is a plane, the guide posts are fixed at intervals to the first surface, and the guide posts are slidably connected to the second plate.

[0009] Preferably, the first plate and the third plate further include a plurality of positioning rods, the positioning rods being distributed between two adjacent guide posts, the elastic component being a compression spring, and the positioning rods being sleeved inside the elastic component.

[0010] Preferably, the first plate and the third plate further include a plurality of damping sleeves, which are uniformly spaced on the first substrate along the vertical direction.

[0011] Preferably, the tabletop includes a second base plate, a bottom plate, and a fastening component. The bottom plate is detachably connected to the bottom surface of the second base plate, the fastening component penetrates through the bottom plate, one end of the fastening component is embedded in the bottom surface of the second base plate, and the other end of the fastening component is detachably connected to the top surface of the second plate.

[0012] Preferably, the fastening component includes a head end and a connecting end that are fixedly connected to each other. The head end is a regular square prism or a regular hexagonal prism, and the connecting end is a screw. A through groove is formed on the bottom surface of the second substrate. The groove width a, the distance b between the two opposite sides of the head end, and the length c of the diagonal of the head end satisfy the following relationship: b≤a<c.

[0013] The beneficial effects of this utility model are as follows: the second plate positions the elastic component, and the elastic component generates elastic force to drive the first plate and the third plate away from each other. Since the first plate and the third plate are both fitted inside the guide mechanism, the first plate and the third plate moving away from each other will press the narrow inner wall of the guide groove along the short diameter of the guide groove. At this time, the relative position of the lifting component and the guide groove is fixed, thereby fixing the height of the small table.

[0014] Since the guide groove is elliptical, when the first plate and the third plate are distributed along the long diameter of the guide groove by the rotating lifting assembly, the elastic component is in a stationary state. The first plate and the third plate will no longer press against the inner wall of the guide groove. At this time, the lifting assembly can move up and down along the guide groove to adjust the height. Attached Figure Description

"Inner" and "outer" refer to the inner and outer parts of a specific outline. "Far" and "near" refer to the distance or proximity relative to a particular component.

[0019] like Figures 1-3 As shown in the figure, an embodiment of the present invention provides a side table with a height-adjustable tabletop, comprising: Cabinet 1; Tabletop 2; The lifting column assembly includes a lifting component, a base 4 and two guide plates 5. The base 4 is fixed inside the cabinet 1. The lower ends of the two guide plates 5 are detachably connected to the base 4. The two guide plates 5 are opposite to each other, and a guide groove extending vertically is formed between the two guide plates 5. The horizontal cross-section of the guide groove is elliptical. The lifting assembly includes a first plate 6, a second plate 7, a third plate 8, and several elastic components. The elastic components are sandwiched between the first plate 6 and the third plate 8. The second plate 7 is distributed between the first plate 6 and the third plate 8. The elastic components pass through the second plate 7. The first plate 6 and the third plate 8 are slidably connected inside the guide groove. The second plate 7 is detachably connected to the bottom surface of the tabletop 2.

[0020] When the first plate 6, the second plate 7, and the third plate 8 are sequentially distributed along the short diameter of the horizontal cross-section of the guide groove, the elastic component is in a compressed state, and the elastic component applies elastic force to the first plate 6 and the second plate 7. The rotating lifting assembly causes the elastic component to be in a compressed state when the first plate 6 and the third plate 8 are distributed along the short diameter of the guide groove. The first plate 6 and the third plate 8 will press against the inner wall of the guide groove along its short diameter, thereby fixing the height of the small table 2.

[0021] When the first plate 6, the second plate 7, and the third plate 8 are distributed sequentially along the long diameter of the horizontal cross-section of the guide groove, the elastic component is in a stationary state. When the rotating lifting assembly is used, the elastic component is in a stationary state when the first plate 6 and the third plate 8 are distributed along the long diameter of the guide groove. The first plate 6 and the third plate 8 will no longer press against the inner wall of the guide groove. At this time, the lifting assembly can move up and down along the guide groove to adjust the height.

[0022] Both the first plate 6 and the third plate 8 include a first substrate. The first substrate includes a first surface and a second surface, both of which extend vertically. The first surface and the second plate 7 are opposite to each other, and the second surface is opposite to the inner wall of the guide groove. The second surface is a rough, arc-shaped surface. The second surface and the inner wall of the guide groove are opposite to each other, and the frictional force that fixes the height of the tabletop 2 is generated by the second surface pressing against the inner wall of the guide groove.

[0023] The first plate 6 and the third plate 8 also include a plurality of guide posts 9. The first surface is a plane, and the guide posts 9 are fixedly spaced on the first surface. The guide posts 9 are slidably connected to the second plate 7. The center line of the guide posts 9 extends radially along the guide groove. The guide posts 9 guide the relative movement direction of the first plate 6 and the third plate 8, so that the first plate 6 and the third plate 8 move horizontally inside the guide groove.

[0024] The first plate 6 and the third plate 8 also include several positioning rods 10, which are distributed between two adjacent guide posts 9. The elastic component is a compression spring, and the positioning rods 10 are sleeved inside the elastic component. The positioning rods 10 position the compression spring, allowing it to extend and retract along the positioning rods 10. This ensures that the direction of the elastic force generated by the compression spring is perpendicular to the first plate 6 and the third plate 8.

[0025] The first plate 6 and the third plate 8 also include several damping sleeves, which are evenly spaced vertically on the first base plate. The damping sleeves generate frictional force that hinders the relative movement of the first plate 6 and the guide plate 5. The damping sleeves also generate frictional force that hinders the relative movement of the third plate 8 and the guide plate 5. Sufficient friction from the damping sleeves helps to fix the height of the tabletop 2. The damping sleeves can be made of hard rubber rings.

[0026] The tabletop 2 includes a second base plate, a bottom plate 3, and a fastening component. The bottom plate 3 is detachably connected to the bottom surface of the second base plate. The fastening component passes through the bottom plate 3, with one end embedded in the bottom surface of the second base plate and the other end detachably connected to the top surface of the second plate 7. The second plate 7 and the second fastener of the tabletop 2 are connected by the fastening component, and the upper end of the fastening component is detachably mounted on the bottom surface of the second base plate via the bottom plate 3.

[0027] The fastening component includes a head end and a connecting end that are fixedly connected to each other. The head end is a regular square prism or a regular hexagonal prism, and the connecting end is a screw. A through groove is formed on the bottom surface of the second base plate. The groove width 'a', the distance 'b' between the two opposite sides of the head end, and the length 'c' of the head end's diagonal satisfy the following relationship: b ≤ a < c. The base plate 3 is symmetrically distributed on both sides of the connecting end. The head end of the fastening component can slide along the through groove to adjust its position. The fastening component is detachably connected to the base plate 3 by a nut, and the relative position of the fastening component and the second base plate can be adjusted.

[0028] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these should all be considered to be within the scope of this specification.
