Problems solved by technology

This kind of limiting method is realized by the cooperation of two components, and requires slotting on the hinge body, which increases the processing steps of the hinge body and makes the structure complicated. In addition, because of the weight of the liquid crystal display, the limiting piece The friction with the limit groove is relatively large, and the limit piece of the limit washer is prone to wear or deformation after long-term use, and the service life is short

Embodiment Construction

[0012] The lifting mechanism provided by the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] see figure 1 The lifting mechanism 10 includes a first pivot assembly 20, a second pivot assembly 30, a first elastic member 40 connected between the first pivot assembly 20 and the second pivot assembly 30, a first link 50, a second Two connecting rods 60 , a first bracket 70 and a second bracket 80 and a rotating assembly 90 .

[0014] Please also see figure 2 and image 3 , the first pivot assembly 20 includes a first pivot seat 21 , two friction members 23 and two limiting members 25 .

[0015] The first pivot seat 21 includes a body 211 , a receiving portion 213 protruding from the body 211 , and a first hook portion 215 protruding from the receiving portion 213 . The body 211 is a rectangular plate. The receiving portion 213 is substantially half-moon-shaped and protrudes from the middle of ...

Abstract

The invention relates to an elevator mechanism, which comprises a first pivoting component, a second pivoting component, a first support, a first connecting rod and a second connecting rod, wherein the first support, the first connecting rod and the second connecting rod are connected with the first pivoting component and the second pivoting component; and the first support is connected with the first pivoting component through a pivot. The elevator mechanism also comprises a locating part sleeved on the pivot; and the limit part is positioned between the first connecting rod and the second connecting rod to limit a rotation angle of the first connecting rod and the second connecting rod relative to the first pivoting component. The elevator mechanism has the advantage of simple and durable structure of a limit unit.

Description

technical field [0001] The invention relates to a lifting mechanism, in particular to a lifting mechanism used on an electronic device. Background technique [0002] With the wide application of computers, their functions are increasing and perfecting day by day, and their volumes tend to be thinner and lighter. Since liquid crystal displays have the advantages of smaller size and lighter weight compared to CRT (Cathode Ray Tube, cathode ray tube) displays, they gradually replace CRT displays as the main components of computers. [0003] In order to facilitate people to watch the liquid crystal display from different viewing angles, the liquid crystal display is usually provided with a lifting mechanism to adjust the height and inclination of the liquid crystal display. Common lifting mechanisms mostly use a hinge structure to adjust the height and inclination of the LCD screen. In order to make the height or inclination change within a suitable range, in the hinge structu...
