[0002] A table is a commonly used furniture for placing items. It can be divided into many categories according to its function. In terms of structure, a table generally includes a table top and supporting feet under the table. The supporting feet of a general table are fixed structures. , and the supporting legs of some foldable tables can be unfolded when in use through the cross foldable structure, and can be folded and folded when not in use, which can greatly reduce the storage space, but the supporting legs of this type of structure It is mainly to realize the storage of the table, and it cannot realize the height adjustment of the table. When using it, only a fixed height can be used. When people use the table, they

Embodiment 1

[0035] Such as Figure 1 to Figure 5As shown, a shrapnel and sector tooth lifting device includes a first cross arm 11 and a second cross arm 12 hinged together, and the hinge point is located in the middle of the first cross arm 11 and the second cross arm 12 . The second cross arm 12 is provided with an auxiliary piece 124 at the hinge shaft 13, the auxiliary piece 124 is affixed to the second cross arm 12, and there is a place for the first cross arm 11 to be inserted between the auxiliary piece 124 and the second cross arm 12. gap. Both sides of the second cross arm 12 and the auxiliary piece 124 are provided with end caps 14 , and the hinge shaft 13 passes through the end caps 14 to hinge the two end caps 14 and the first cross arm 11 and the second cross arm 12 together. The first cross arm 11 is provided with a spring piece 111 and a card 112 near the hinge shaft 13, the elastic end of the spring piece 111 abuts against the card 112, and the first cross arm 11 is provi...

Embodiment 2

[0043] An elevating platform comprising a shrapnel and a fan-shaped tooth elevating device, the other structures are the same as in Embodiment 1, and the similarities will not be repeated here, except that:

[0044] Such as Figure 6 to Figure 8 As shown, the lifting platform is provided with two X-shaped support structures, any one of which is the shrapnel and fan-shaped tooth lifting device 10 described in the present application, and the other side is an ordinary X-shaped support structure, that is, two cross arms are hinged It is used to support the table top 20 and lift and descend following the shrapnel and the fan-shaped tooth lifting device 10, and does not have structures such as spring pieces 111 and cards 112 itself.

Abstract

The invention relates to a lifting device for shrapnel and sector teeth, comprising a first cross arm and a second cross arm hinged together, the hinge point is located in the middle of the first cross arm and the second cross arm, and the first cross arm is located near the hinge axis The position of the spring and the card are provided, and the elastic end of the spring is in contact with the card. The first cross arm is provided with a spring positioning hole for accommodating the spring and the card, and the second cross arm is provided with a number of teeth corresponding to the card. The lifting table of the shrapnel and fan-shaped tooth lifting device described in one item includes a table top and a table foot, and a table rail is provided at the bottom of the table. One end of the other cross arm is slidably connected to the table track; when the horizontal positions of the lower ends of the first cross arm and the second cross arm remain unchanged, the upper horizontal positions of the first cross arm and the second cross arm rise or fall, And each tooth position corresponds to a height position, and can stop at any level in the middle.

Description

technical field [0001] The invention relates to the field of lifting platforms, in particular to a lifting device for shrapnel and sector teeth and a lifting platform including the lifting device.
