Description

TW3182PA 200817622 # IX, invention description: [Technical Field] The present invention relates to a lifting support device and a display device using the same, and more particularly to an adjustable support device for adjusting the height of a display screen and using the same Display device. [Prior Art] Nowadays, when electronic products such as televisions or flat panel displays are used, most of them will be matched with the base. In addition to supporting these f-electronic products, these bases have more or less the ability to adjust the height and angle of rotation to meet user needs. For example, the lifting and supporting device of the conventional liquid crystal display is usually designed by the design of elastic force, gravity and friction. Please refer to Fig. 1, which shows the schematic of a conventional lifting support device. As shown in Fig. 1, the lifting support device 1 includes a bottom plate 11, a first casing 12, a second casing 13, and a constant force spring 14. The first housing 12 is vertically disposed on the bottom plate 11, and the weight of the first housing 12, the second housing 13 and the constant force spring 14 is supported by the bottom plate 11. The second housing 13 is slidably coupled to the first housing 12. The electronic product (not shown) is mounted on the second casing 13 to adjust the height of the electronic product by sliding the second casing 13 relative to the first casing 12. One end of the constant force spring 14 is rotatably disposed on the second casing 13 and the other end is fixed to the inner side surface of the first casing 12. When the second housing 13 is biased to move downward, the constant force spring 14 is stretched, 7

'W3182PA 200817622 The elastic force (elastic restoring force) of the Cosmetology magazine 14 is applied to the first casing 12 and the second casing 13 at the same time. Since one end of the constant force spring 14 is fixed to the first casing 12, a thrust is generated to the second casing 13 to push the second casing 13 upward. When the electronic product is mounted on the lifting support device 1, the lifting adjustment of the lifting support device 1 is mainly caused by the friction between the inner casing surface of the first casing 12 and the outer casing surface of the second casing 13, the constant force spring 14 The elastic force, the second housing 13 and the electronic products mounted thereon and the gravity of other parts are controlled. In general, gravity and spring force are constant, and the frictional force is not completely consistent in the process of pushing up and down the second casing 13, so that the mechanism of lifting is mainly controlled by friction. Since the constantness of the friction is poor, it is easy to automatically or automatically fall, so the design of this type of lifting support device is difficult for the designer. Since the friction of each product must be regulated on the production line, the instability of the product is increased. SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a lifting support device and a display device using the same, and a positioning switch and a stop portion are designed in the lifting support device to adjust the lifting mechanism. Allows the user to control the lift simply by performing a simple operation. In the design of the positioning switch and the stop, the problem of automatic or automatic falling can be effectively solved. In addition, since the slider is used as the sliding interface between the first housing and the second housing, the frictional force between the first housing and the second housing is greatly reduced.
