Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0016] like Figures 1-5 As shown, an embodiment of the present invention discloses a foldable height-adjustable table, including a height-adjustable table body, the height-adjustable table body including a table frame and a tabletop 10, the tabletop being fixedly disposed on the top of the table frame, the table frame being formed by two parallel long frame tubes 11 and two parallel short frame tubes 12, and one long frame tube 11 being fixedly connected to an adjacent short frame tube 12. The lifting table body 1 is lifted by a lifting mechanism, and the lifting mechanism and a folding mechanism capable of folding the lifting table body enable the lifting table to be in a folded state when the lifting table body is lowered to the lowest point. The folding mechanism comprises an inner side leg support 20 and an outer side leg support 21, and the two ends of the outer side leg support 21 are respectively hinged to the middle parts of the two sides of the inner side leg support 20. Two groups of sliding groove groups are respectively arranged on the two inner sides of the long frame tube 11, each group of sliding groove groups comprises two sliding grooves 22 arranged in parallel, a table leg connecting tube 23 is arranged between the two sliding grooves 22 in the same group, and the two ends of the table leg connecting tube 23 are respectively connected to the two sliding grooves 22 on the corresponding side in sliding mode; one of the table leg connecting tubes 23 is fixedly connected to the top of the inner side leg support 20, and the other table leg connecting tube 23 is fixedly connected to the top of the outer side leg support 21. The middle parts of the two table leg connecting tubes 23 are fixedly connected to the connecting iron pieces 24. The lifting mechanism comprises a nitrogen spring 30, a connecting square tube 31 and a first connecting iron sheet 32, one end of the nitrogen spring 30 is fixedly connected to the side surface of one end of the connecting square tube 31 through an L-shaped iron sheet 33, the bottom surface of the other end of the connecting square tube 31 is fixedly connected to the middle part of the top of the first connecting iron sheet 32, one end of the bottom of the first connecting iron sheet 32 is hingedly connected to a second connecting iron sheet 33, the other end of the bottom of the first connecting iron sheet 32 is hingedly connected to a third connecting iron sheet 34, the other end of the second connecting iron sheet 33 is hingedly connected to one of the connecting iron pieces 24, and the other end of the third connecting iron sheet 33 is hingedly connected to the other connecting iron piece 24.

[0017] The lifting structure of the lifting table of the embodiment is simple, and the lifting table as a whole is relatively light, so the lifting table can be lifted and no noise is generated during lifting by the above-mentioned arrangement. The specific lifting adjustment process is that when the lifting table needs to be lowered to the lowest position, the piston rod of the nitrogen spring is moved to the right, thereby driving the one end of the connecting square tube connected thereto to move to the right, and the other end of the connecting square tube moves to the left. Thus, the second connecting iron sheet hingedly connected to the one end of the connecting square tube moving to the right moves to the right, thereby driving the connecting iron piece on the corresponding side to move to the right; at the same time, the third connecting iron sheet hingedly connected to the one end of the connecting square tube moving to the left moves to the left, thereby driving the connecting iron piece on the corresponding side to move to the left; the two table leg connecting tubes respectively move in the sliding grooves in the direction away from each other, thereby driving the lower ends of the inner side leg support and the outer side leg support to also move in the direction away from each other synchronously, thereby realizing the lowering of the lifting table to the lowest position and the complete folding state, so that the lifting table is conveniently stored when not in use.

[0018] When it is needed to raise the lifting table to the highest position, the piston rod of the nitrogen spring can be moved to the left, thereby moving the one end of the connecting square tube connected therewith to the left and moving the other end of the connecting square tube to the right. Thus, the second connecting iron sheet hinged to the one end of the connecting square tube moving to the left drives the connecting iron piece on the corresponding side to move to the left, and the third connecting iron sheet hinged to the one end of the connecting square tube moving to the right drives the connecting iron piece on the corresponding side to move to the right, so that the two table corner connecting tubes are moved to each other, thereby driving the lower ends of the inner side leg supports and the lower ends of the outer side leg supports to move to each other, and then the lifting table is raised to the highest position.

[0019] In the embodiment, the other end of the nitrogen spring 30 is fixedly connected with the nitrogen spring connecting assembly 4, the nitrogen spring connecting assembly 4 is fixedly arranged on the top of the welding iron block 5, the welding iron block 5 is fixedly arranged on the inner side of one end of one of the long frame tubes 11, the nitrogen spring connecting assembly 4 is connected with the nitrogen spring starting assembly 6 through a pipeline, and the nitrogen spring starting assembly 6 is fixedly arranged on the inner side of the middle part of one of the short frame tubes 12.

[0020] It should be noted that the nitrogen spring starting assembly 6 in the embodiment includes a pulling block 60, a limiting plate 61 and a U-shaped mounting bracket 62, and the bottom of the pulling block 60 is rotatably connected with the U-shaped mounting bracket 62. One side of the pulling block 60 is fixedly connected with the pipeline, and the other side of the pulling block 60 is located on the side of the limiting plate 61 away from the pipeline.

[0021] The embodiment can achieve the following effects through the above arrangement. When it is needed to lower the lifting table to the lowest position, the pulling block is manually pulled to move outward, thereby driving the piston rod of the nitrogen spring to move to the right; when it is needed to raise the lifting table to the highest position, the pulling block is manually pulled to move inward, thereby driving the piston rod of the nitrogen spring to move to the left, so that the height position of the lifting table is adjusted. Meanwhile, the nitrogen spring is arranged to be infinitely adjusted within the effective telescopic distance thereof, and the pressure resistance thereof can meet the bearing requirement of furniture.

[0022] In the embodiment, two first table top bearing patches 7 and two second table top bearing patches 8 are further arranged between the two long frame tubes 11, and the two ends of the two first table top bearing patches 7 and the two ends of the two second table top bearing patches 8 are fixedly connected with the inner sides of the two long frame tubes 11, respectively. The top of the two first table top bearing patches 7 and the top of the two second table top bearing patches 8 are fixedly connected with the bottom of the table top plate 10.

[0023] The embodiment can achieve the mounting and fixing of the two first table top bearing patches and the two second table top bearing patches through the above arrangement.

[0024] In this embodiment, the bottom center of the two second desktop load-bearing patches 8 is fixedly connected to both ends of the fourth connecting iron plate 9, and the bottom of the fourth connecting iron plate 9 is hinged to the top of the connecting square tube 31.

[0025] This embodiment enables the installation of the fourth connecting iron plate through the above-described settings.
