DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and beneficial effects of the utility model more clearly understood, the technical scheme in the utility model will be further described below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0023] Referring to Figs. 1-2The utility model provides a kind of portable table, comprising:

[0024] Table board 1 has inner chamber 101 with opening downward;

[0025] Bottom plate 2 is liftable along up and down;

[0026] Connecting assembly, including at least one group of first connecting rod 3 and second connecting rod 4 arranged in cross, two ends of the first connecting rod 3 are hinged to the table board 1 and the bottom plate 2 respectively, one end of the second connecting rod 4 is hinged to the table board 1, and the other end is movably connected to the bottom plate 2, under the action of external force, the second connecting rod 4 has first state and second state, in the first state, the included angle between the first connecting rod 3 and the second connecting rod 4 gradually decreases, for making the bottom plate 2 unfold below the inner chamber 101, in the second state, the included angle between the first connecting rod 3 and the second connecting rod 4 gradually increases, for making the bottom plate 2 hide in the inner chamber 101;

[0027] Driving part, for driving the second connecting rod 4 to switch between first state and second state.

[0028] In this embodiment, the table board 1 is designed with a downwardly opening inner chamber 101, which provides a hidden space for the bottom plate 2, ensuring the compactness of the table when not in use. The bottom plate 2 can be adjusted in the up-down direction to hide in the inner chamber 101 when not in use, or to be lowered away from the table board 1 when in use. A connecting assembly is provided between the table board 1 and the bottom plate 2, which is composed of at least one set of first connecting rods 3 and second connecting rods 4 arranged in cross. To ensure stability, the connecting assembly can be provided with two or more sets. In this embodiment, one set of first connecting rods 3 and second connecting rods 4 arranged in cross is taken as an example. The two ends of the first connecting rod 3 are hinged to the table board 1 and the bottom plate 2, and one end of the second connecting rod 4 is hinged to the table board 1, and the other end is movably arranged on the bottom plate 2. The first connecting rod 3 and the second connecting rod 4 form a frame structure that can change shape. When an external force is applied, the relative position of the second connecting rod 4 to the first connecting rod 3 will change, so that the second connecting rod 4 has two states, thereby driving the bottom plate 2 to unfold or fold. In the first state, the end of the second connecting rod 4 on the bottom plate 2 moves relative to the first connecting rod 3 and gradually approaches the end of the first connecting rod 3 on the bottom plate 2, and the included angle between the two gradually decreases, thereby driving the bottom plate 2 to unfold below the inner chamber 101. In the second state, the end of the second connecting rod 4 on the bottom plate 2 moves relative to the first connecting rod 3 and gradually moves away from the end of the first connecting rod 3 on the bottom plate 2, and the included angle between the two gradually increases, thereby driving the bottom plate 2 to hide in the inner chamber 101. The driving member is used to control the conversion of the second connecting rod 4 between the first state and the second state, thereby realizing the unfolding and folding of the bottom plate 2. The driving member can drive the included angle of the second connecting rod 4 to the first connecting rod 3, that is, control the overall height of the table.

[0029] The table board 1 and the bottom plate 2 are respectively provided with first hinge points 5 and second hinge points 6, and the two ends of the first connecting rod 3 are arranged at the first hinge points 5 and the second hinge points 6. Further, the table board 1 is provided with third hinge points 7, and the end of the second connecting rod 4 close to the table board 1 is arranged at the third hinge points 7.

[0030] In this embodiment, the two ends of the first connecting rod 3 are arranged at the first hinge points 5 and the second hinge points 6, and the end of the second connecting rod 4 close to the table board 1 is arranged at the third hinge points 7, and the other end is movably arranged on the bottom plate 2. When the second connecting rod 4 moves away from the second hinge point 6, the second connecting rod 4 rotates counterclockwise around the third hinge point 7, and the first connecting rod 3 rotates clockwise around the first hinge point 5 with the second hinge point 6 as the support point, and the included angle between the first connecting rod 3 and the second connecting rod 4 gradually decreases, thereby driving the bottom plate 2 to unfold below the inner chamber 101.

[0031] The driving member comprises a threaded rod 8 rotatably arranged on the bottom plate 2 and a sliding block 9 sleeved on the threaded rod 8, and one end of the second connecting rod 4 close to the bottom plate 2 is hinged to the sliding block 9.

[0032] In the embodiment, the driving member is a threaded rod 8 rotatably arranged on the bottom plate 2 and a sliding block 9 sleeved on the threaded rod 8, and one end of the second connecting rod 4 close to the bottom plate 2 is hinged to the sliding block 9. Under the rotation of the threaded rod 8, the sliding block 9 slides on the threaded rod 8, and the second connecting rod 4 is connected and slides, realizing the lifting function of the bottom plate 2, and the threaded rod 8 can freely control the lifting height of the bottom plate 2.

[0033] The sliding block 9 is provided with a supporting rod 10, and one end of the second connecting rod 4 close to the bottom plate 2 is provided with a supporting hole 11, and the supporting rod 10 is rotatably inserted into the supporting hole 11.

[0034] In the embodiment, the sliding block 9 is provided with a supporting rod 10, and one end of the second connecting rod 4 close to the bottom plate 2 is provided with a supporting hole 11, and the supporting rod 10 is rotatably inserted into the supporting hole 11, ensuring that the second connecting rod 4 can flexibly follow the movement of the sliding block 9. Further, the bottom plate 2 is provided with a guide rail 12, and the supporting rod 10 is slidably arranged in the guide rail 12. The supporting rod 10 is provided with a plurality of rollers 13, and the rollers 13 are located on the side of the second connecting rod 4. The design of the supporting rod 10 on the sliding block 9 and the supporting hole 11 on the second connecting rod 4 ensures the flexibility and stability of the connection, avoids jamming and wear, and the guide rail 12 is arranged on the bottom plate 2, the supporting rod 10 is slidably arranged in the guide rail 12, and a plurality of rollers 13 are arranged on the supporting rod 10 to reduce friction, ensuring that the movement of the supporting rod 10 is smoother when the sliding block 9 moves.

[0035] The table plate 1 and the bottom plate 2 are detachably provided with a stand column 14, and the stand column 14 has a telescopic structure for supporting the table plate 1 in a first state.

[0036] In the embodiment, when the second connecting rod 4 approaches the second hinge point 6, the center of gravity of the table plate 1 is unstable, and the stand column 14 with a telescopic structure can be selected to abut between the table plate 1 and the bottom plate 2 at an adaptive height when the second connecting rod 4 is stationary, so as to increase the stability.

[0037] One of the table plate 1 and the bottom plate 2 is provided with a receiving opening 15 for receiving the stand column 14 in a second state.

[0038] In the embodiment, the receiving opening 15 for receiving the stand column 14 is arranged on the table plate 1, which is convenient for carrying.
