As shown, the lift support frame comprises an upper beam 3, a lower beam 4, a drive mechanism and a lift support 6. In the scheme, the upper beam 3 and the lower beam 4 are both in a straight structure, and only two guide support columns 7 are arranged between the upper beam 3 and the lower beam 4. In this scheme, the upper beam 3 and the lower beam 4 both have a head end and a tail end along the length direction, one of the guide support columns 7 is vertically arranged between the head end of the upper beam 3 and the head end assembly of the lower beam 4, the other guide support column 7 is vertically arranged between the tail end of the upper beam 3 and the tail end of the lower beam 4, and the two ends of each guide support column 7 are uniformly distributed with the upper beam 3 and the lower beam 4 to be fixedly connected, so that the upper beam 3 and the lower beam 4 are matched with the two guide support columns 7 to form a square structure. Lifting support 6 is located between upper beam 3 and underbeam 4 on vertical direction, and this upgrading support is all vertically run through to two guide support post 7.

The driving mechanism comprises a driving assembly and a screw rod 5, the screw rod 5 is vertically arranged between the upper beam 3 and the lower beam 4 and can rotate around the axis of the screw rod 5, and the screw rod 5 is positioned between two guide support columns 7 along the length direction of the upper beam 3. The lifting support 6 is located vertically between the upper beam 3 and the lower beam 4, and the lead screw 5 also vertically penetrates through the lifting support. Meanwhile, the screw rod 5 is also provided with a nut 15, and the nut 15 and the lifting support member 6 are kept relatively fixed in the length direction of the screw rod 5. The driving component acts on the screw 5 or the nut 15 to drive the nut 15 and the lifting support 6 to move along the height direction of the screw 5.

As a specific embodiment, referring to fig. 2 and 3, the driving assembly in this embodiment includes a driving motor 11, a worm 14 and a worm wheel 13, wherein the driving motor 11 and the lifting support 6 are relatively fixed. The driving motor 11 is further provided with a box body 12, the driving worm wheel 13 and the worm 14 are contained in the box body 12, an output shaft of the driving motor 11 penetrates through the side wall of one side of the box body 12, extends into the box body 12 and is connected with the worm 14, and the worm 14 is meshed with the worm wheel 13. Meanwhile, the worm wheel 13 is coaxially provided with a transmission rod, and the transmission rod penetrates through one side of the box body 12 and is exposed out of the box body 12. The transmission rod is provided with a first bevel gear 18, the screw 15 is coaxially provided with a second bevel gear 19, and the first bevel gear 18 is meshed with the second bevel gear 19. In addition, a cavity is formed in the lifting support member 6, the screw 15, the first helical gear 18 and the second helical gear 19 are all accommodated in the cavity of the lifting support member 6, and the screw 15, the first helical gear 18 and the second helical gear 19 are all fixed with the lifting support member 6 along the length direction of the lead screw 5. The lead screw 5 penetrates through the upper end face and the lower end face of the lifting support member 6 to be in spiral fit with the nut 15. When the driving motor 11 drives the worm 14 to rotate, the worm 14 drives the worm wheel 13 to rotate, and the worm wheel 13 drives the screw 15 to lift along the length direction of the screw rod 5 through the first helical gear 18 and the second helical gear 19, so as to drive the lifting support member 6 to lift along the height direction of the guide support column 7. And the lifting support member 6 is connected to the table 1. The lifting support pieces 6 on the lifting support 2 at two sides of the table plate 1 drive the table plate 1 to synchronously lift when lifting along the height direction of the guide support columns 7.

Preferably, as shown in fig. 2, a cross beam 17 is disposed between the lifting support members 6 in the two lifting brackets 2 in the present solution, the cross beam 17 connects the two lifting support members 6 into a whole, and the cross beam 17 abuts against the bottom end surface of the table board 1. The cross beam 17 not only enables the lifting support members 6 in the two lifting brackets 2 to be kept at the same height all the time, but also prevents the table plate 1 from being inclined due to the fact that the lifting support member 6 at one side is too high in lifting height and the lifting bracket 2 at the other side is relatively low in lifting height. Meanwhile, the cross beam 17 can also form a bottom support for the table board 1 so as to improve the strength of the whole structure.

Simultaneously, lift support piece 6 includes first supporting shoe 8 and second supporting shoe 9 in this scheme, and wherein first supporting shoe 8 is located the top of second supporting shoe 9 on vertical direction, through connecting piece 10 fixed connection between first supporting shoe 8 and the second supporting shoe 9. And the drive assembly is arranged on the first support block 8. It is easy to understand that, because the driving component is disposed on the first supporting block 8, and the first supporting block 8 is located above the second supporting block 9, when the second supporting block 9 descends to abut against the lower beam 4, a space is still left between the driving component and the ground, so as to protect the driving component.

In addition, in this scheme, the interval between two guide support posts 7 is 20 ~ 40 cm. And the length of the guide support column 7 is 180-220 cm. It will be readily understood that the height of the lifting bracket 2 is the height of the guide support column 7 plus the thickness of the upper beam 3 and the thickness of the lower beam 4. The length of the guide support pillars 7 may enable the table 1 to be switched between a standing position and a sitting position. When the table board 1 is lifted to the standing position, the user can stand and use the table board 1, and the table board 1 is approximately positioned in the chest of the user. When the table 1 is lowered to the seating position, the user can sit on the chair and use the table 1, the table 1 still being in a substantially chest position. Similarly, the width of the lifting bracket 2 is the space between the two guide support columns 7 plus the width of the two guide support columns 7. Because the interval between two guide support posts 7 is only 20 ~ 40cm, the width of lifting support 2 will be narrower relatively, is difficult for taking place the interference with other parts. And because only two guide support columns 7 are arranged between the upper beam 3 and the lower beam 4, the screw rod 5 is positioned between the two guide support columns 7, the space is sufficient, and the installation of the screw rod 5 cannot be influenced.

Example 2: referring to fig. 4 and 5, the main difference between this embodiment and the lifting table in embodiment 1 is that the driving assembly in this embodiment includes a driving motor 11, a worm 14, a worm wheel 13 and a box 12, wherein the driving motor 11 and the lifting support 6 are relatively fixed. The case 12 is fixedly installed on the driving motor 11, and the nut 15, the worm 14, and the worm wheel 13 are all housed inside the case 12. An output shaft of the driving motor 11 penetrates through a side wall of one side of the box body 12, extends into the box body 12 and is connected with the worm 14, and the worm 14 is in meshing transmission with the worm wheel 13. The worm wheel 13 is coaxially provided with the nut 15. The screw rod 5 on the lifting bracket 2 penetrates through the box body 12, the screw nut 15 and the worm wheel 13 and is in spiral fit with the screw nut 15. When the driving motor 11 drives the worm 14 to rotate, the worm 14 drives the worm wheel 13 to rotate so that the nut 15 ascends and descends along the length direction of the screw rod 5. Meanwhile, the nut 15 drives the driving motor 11 through the box body 12 to support the lifting support piece 6 to do lifting action along the height direction of the guide support column 7.

Because the nut 15 is accommodated in the box body 12, the box body 12 is fixedly connected with the driving motor 11, and the driving motor 11 can synchronously move along with the nut 15 in the lifting process so as to support the lifting support member 6 to do lifting motion. In the process, the driving motor 11 is not only a driving part but also a supporting part, and plays a role in supporting the lifting supporting part 6 and the table board 1. And the whole structure only needs one worm 14 and worm wheel 13 assembly to realize transmission, and the structure is compact and small, and is convenient to install on the lifting support piece 6.

It should be noted that, in the present embodiment, the structures and the assembly relationships of the upper beam 3, the lower beam 4, the guiding and supporting columns 7 and the lifting and supporting members 6 in the lifting bracket 2 are all the same as those in embodiment 1, so the structures and the assembly relationships of the upper beam 3, the lower beam 4, the guiding and supporting columns 7 and the lifting and supporting members 6 are not shown in fig. 4, but the structures thereof are also clear.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
