Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Such as figure 1 As shown, a computer expansion card pressing and fixing device of the present invention includes a body 2 as a supporting structure of the whole device, and also includes a lateral movement mechanism and a pressing plate mechanism; wherein:

[0015] The lateral movement mechanism is composed of a push screw 4 installed on the body 2 and a screw sleeve on the screw 4 that can move along the axial direction of the screw with the screw 4. The screw end of the push screw 4 is arranged on the outer end of the body; The front and rear movement of the slide block is realized by turning the screw rod left and right.

[0016] The pressure plate mechanism is composed of a pressure plate 5 that can rotate around the positioning shaft 6 fixed on the body and a pressure plate rebound spring 7; the pressure plate rebound sp...

Abstract

The invention discloses a simply structured, low-cost and stably used pressing fixing device for a computer expansion card. The pressing fixing device comprises a main body, a lateral moving mechanism and a pressing plate mechanism, wherein the lateral moving mechanism is composed of a pushing screw rod and a sliding block; the pushing screw rod is mounted on the main body; the sliding block is sleeved on the pushing screw rod with the help of threads and can move along the axial direction of the pushing screw rod following the rotation of the pushing screw rod; the pressing plate mechanism is composed of a pressing plate and a pressing plate rebounding spring; the pressing plate can rotate around a positioning shaft fixed on the main body; the sliding block is clung to an inside wall of the pressing plate; one end of the inside wall that closes to the positioning shaft has a wedge-shaped structure; and the movement of the sliding block is switched to the opening and closing of the pressing plate with the help of the wedge-shaped structure. The pressing fixing device provided by the invention has the advantages that developing and manufacturing costs are low, assembling and use are simple, a structure is compact, an interior space of the whole device is greatly saved, an expansion card is more stably pressed and fixed during a use process, and various expansion cards in different dimensions can be pressed and fixed in a chassis at the same time.

Description

technical field [0001] The invention relates to a scheme for installing and fixing computer function expansion cards, in particular to a computer expansion card pressing and fixing device. Background technique [0002] Industrial computers often need to be equipped with multiple cards in one machine. At present, the installation and fixing methods of computer function expansion cards in the industry are mostly fixed by semicircular rotation and compression and screw extension. This type of solution has a large structure and high development cost, and has certain limitations on the height and dimension of the PCB part of the board. Contents of the invention [0003] In view of the above problems, the present invention aims to provide a computer expansion card pressing device with simple and compact structure, low cost and stable use. [0004] In order to achieve this technical purpose, the solution of the present invention is: a computer expansion card pressing and fixing ...
