Display lifting device

The present invention relates to a lifting device, and more particularly to a display lifting device.

In the past, in order to enable the position of the display to be quickly adjusted to the position and height of the display depending on the user, a single-type lifting display lifting device has been developed. It supports the weight of the display through a constant force spring in the lifting device.

However, each display of different sizes has different weights, and the heavier weight requires a spring with a larger supporting force. Therefore, the conventional single-size display lifting device can only be applied to a single-size display corresponding to each other. . Therefore, whenever the size of the display is different, it is also necessary to assemble with different single-size display lifting devices, but this will increase the manufacturing cost and also make it necessary to replace the size of the display. Replace the appropriate display lifts.

In addition, although an adjustable lifting device that utilizes the force of adjusting the compression spring to change its load capacity has been developed. However, when the user uses such an adjustable lifting device that adjusts the strength of the compression spring, the adjustment process will be very time consuming and the adjusted result will be adjusted when assembling the display of different sizes and sizes. It may also be impossible to achieve the load-bearing capacity required for the loaded display.

In view of the above problems, the present invention provides a display lifting device that cuts through The spring used to load the display is changed so that when the display of different specifications is loaded, it is only necessary to adjust the lifting device to the appropriate load capacity by switching the switch.

In order to achieve the above objective, an embodiment of the present invention provides a display lifting device including a support frame, a limit seat, a carrier, a first fastener, a second fastener, and a first force. a piece, a second constant force piece and a switch. The support frame has a supporting surface, and the limiting seat is disposed on the supporting surface, and the bearing seat is slidably disposed on the supporting frame. The first card firmware and the second card firmware are disposed on the carrier. One end of the first force-fixing member is fixed to the first fastener, and the other end of the first force-applying member is connected through the carrier. One end of the second force-fixing member is fixed to the second fastener, and the other end of the second force-applying member is connected through the carrier. The switch is disposed on the limit seat, and the switch is switched to a first position connected to the first fastener to be operated together with the first force member or to be connected to the second card to The second position of the second force-applying member is actuated together.

The utility model can be provided in the display lifting device provided by the embodiment of the invention, which can switch the position of the switch by selecting the force-changing member to be adjusted to adjust the display lifting device, so that the display lifting device has the display and the display The weight is consistent with the load capacity.
