For example, the Chinese patent No. 200920026066.2 discloses an electric lift table, including a desktop, a motor, a cross bar, a vertical rod, a transmission shaft, etc., the cross rod is directly fixed with the vertical rod, and the vertical rod and the motor are connected by a drive shaft. The following defects generally exist in existing lift tables:

The assembly of the entire product usually requires a certain degree of professionalism, and professionals need to go to the user's site to assemble and debug the components one by one, which increases the cost of personnel for the seller. For such defects, people usually complete the entire assembly of the table before leaving the factory, and then send it to the buyer in a large package. During the entire assembly process, the installation requirements of the crossbar and the column are the highest, and the structure of this part occupies the most packaging and transportation space. However, the horizontal bar and the vertical bar are usually directly fixed together and cannot be folded, which is inconvenient for packaging.

Utility model content

A foldable support device, comprising a beam and a lifting mechanism, the lifting mechanism includes at least a pair of lifting columns that are arranged oppositely, and the lifting columns are respectively connected to the ends of the beam through a connecting device, one end of the connecting device is connected to the lifting column. The column is fixedly connected, and the other end is rotatably connected to the beam.

The connection device includes a connection code fixed on both sides of the upper end of each lifting column, and the other end of the connection code away from the lifting column is provided with a shaft hole, and the connection code and the beam are installed on the shaft hole. The end of the movable pin is connected, and the lifting column is integrated with the connecting yard and rotates around the beam with the movable pin as the axis, thereby performing folding.

Preferably, reinforcing ribs are provided on the connecting bracket.

The lifting column of the support device is connected with the beam through the connecting code, and the lifting column and the connecting code can be folded around the beam together, so that the floor space is reduced during transportation, the packaging size is relatively small, and it is easy to store and transport; Moreover, when installing, the user only needs to follow the instructions to install the foldable lifting table, and the installation effect can be guaranteed; there are also U-shaped protruding ribs on the surface of the connecting code body, which further improves the carrying capacity of the connecting code .

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figures 1 and 2, an embodiment of a foldable support device of the present invention includes a beam 2 and a lifting mechanism 3, and the lifting mechanism 3 includes at least a pair of lifting columns 31 that are arranged oppositely. The columns 31 are respectively connected to the ends of the crossbeam 2 through connecting devices 5 , one end of the connection device 5 is fixedly connected to the lifting column 31 , and the other end is rotatably connected to the crossbeam 2 .

The connecting device 5 includes a pair of connecting codes respectively positioned at both sides of the lifting column 31, the lifting column 31 on the left side is connected with the beam 2 through a pair of short connecting codes 51, and the lifting column 31 on the right side is connected with a pair of long connecting codes 51. Connected with the beam 2, one end of the connection code is fixedly installed on both sides of the upper end of the outer tube 312 of the lifting column 31 by four screws; the other end of the connection code is provided with a shaft hole 511, and the connection code is connected to the The crossbeam 2 is connected by the movable pin 52 inserted from the shaft hole 511, the lifting column 31 and the connection code 51 are connected as a whole and rotate around the crossbeam 2 with the movable pin 52 as the axis, so as to be folded, as shown in Figure 1 Folding is performed to obtain the folded scene as shown in FIG. 2 . the

As shown in 3, the first mounting hole 512 is provided on the connection code to be fixedly installed with the lifting column 31 by screws and other fasteners, and there is also a first installation hole 512 which is fixed and installed with the beam 2 by screws and other fasteners around the shaft hole 511. The second installation hole 513, in this embodiment, according to the principle of three-point positioning, the first installation hole 512, the second installation hole 513 is set at least 3, in order to make the installation more firm, can increase the installation hole appropriately; U-shaped protruding reinforcing ribs 514 are also provided on the surface of the connecting code body, which further improves the bearing capacity of the connecting code.

In order to avoid the situation that the folded two lifting columns 31 are located on the same horizontal plane so that the ends overlap or even interfere and cannot be placed, thereby requiring a larger placement space, the connection codes connected to the two lifting columns 31 are set to be long and short. The two different ones are connection codes (51, 51ˋ), which can solve the above problems well. In this embodiment, the short connection code 51 is connected as shown in the figure. 1 and 2 are located on the left column, and the long connection Code 51 is connected as shown in Figure 1 and 2 and is positioned on the column on the right, wherein in the implementation process short connection code 51 and long connection code 51 are interchangeable with the installation position of the column.

The lifting column 31 is connected to the beam 2 through the connecting code, and the lifting column 31 and the connecting code can be folded around the beam 2, so that the floor space is reduced during transportation, the packaging size is relatively small, and it is easy to store and transport ; and when installing, the user only needs to follow the instructions to install the foldable lift table, and the installation effect can be guaranteed.

As shown in Figure 4, the utility model is used in the embodiment on the lifting table, and the lifting table includes a desktop 1, a crossbeam 2 supported on the bottom of the desktop 1, a lifting mechanism 3 and a driving mechanism 4 for driving the lifting mechanism 3 to lift. , as shown in Figure 1-4, first unscrew the lifting column 31 as shown in Figure 2, perpendicular to the beam 2, install the driving mechanism 4 on the beam 2, and connect the power supply, install the caster 8 on the foot 7 , and the lifting column 31 is fixedly connected with the connection code, the beam 2 and the connection code through fasteners such as screws, and the anchor 7 is placed on the lifting column 31 and fixed and installed through fasteners such as screws; the support arms 6 are respectively Install it on the lifting column 31, then install the hand controller on the beam 2, switch on the power supply, and adjust the lifting by the hand controller.

In a word, the above descriptions are only preferred embodiments of the present utility model, and all equal changes and modifications made according to the patent scope of the utility model should fall within the scope of the utility model patent.
