Abstract

A fixing device for a planar display panel includes a fastening fixture for fixing the planar display panel on a carrier stage in which a plurality of slide slots are provided. The fastening fixture includes a driving rod capable of being inserted into one of the slide slots, a fixture body and a bottom plate. The driving rod is connected with the fixture body and the bottom plate, which are respectively provided on two sides of the carrier stage in operation, and a spring is wound around the driving rod and capable of driving the bottom plate to move.

Claims

1. A fixing device for a planar display panel, including a fastening fixture for fixing the planar display panel on a carrier stage in which a plurality of slide slots are located, wherein the fastening fixture includes:

a driving rod capable of being inserted into one of the slide slots;

a fixture body; and

a bottom plate, wherein the driving rod is connected with the fixture body and the bottom plate, which are respectively located on two sides of the carrier stage in operation, and a spring is wound around the driving rod and capable of biasing the bottom plate towards the fixture body;

wherein a through hole is provided in the fixture body, into which the driving rod is inserted, the driving rod is provided with a press lever at a first end and fixed on the bottom plate at a second end, a first overhang lever is located on the driving rod, the spring is disposed in the through hole under the first overhang lever, the first overhang lever has a length extending radially that is larger than the diameter of the spring, and the diameter of the through hole at a middle portion of the through hole is smaller than the diameter of the spring; and

wherein a second overhang lever is located on the driving rod under the first overhang lever, a groove is located in an inner wall of the through hole at the middle portion of the through hole and adapted for the second overhang lever to slide therein, a length of the groove extending in an axial direction of the through hole is smaller than the depth of the through hole wherein the groove is not formed in an upper portion and a lower portion of the through hole, the spring is located above the groove and between the first and second overhang levers, and the groove has a length extending radially that is larger than or equal to a length extending radially of the second overhang lever, wherein pressing the press lever compresses the spring as the second overhang lever slides within the groove, the driving rod moving the bottom plate away from the carrier stage and allowing the position of the fastening fixture to be adjusted.

2. The fixing device as claimed in claim 1, wherein the first overhang lever is of an in-line shape or a crossed shape.

3. The fixing device as claimed in claim 1, wherein the second overhang lever is of an in-line shape or a crossed shape.

4. The fixing device as claimed in claim 1, wherein a plurality of groups of locating holes are provided at two sides of each slide slot, and locating pins are provided at two ends of the bottom plate corresponding to the locating holes.

5. The fixing device as claimed in claim 4, wherein catch holes are provided in the fixture body corresponding to the locating pins.
