Description
Technical Field
The invention relates to an installation and fixation scheme of a computer function expansion card, in particular to a computer expansion board card pressing and fixation device.
Background
In an industrial computer, equipment with one machine and multiple cards is required to be configured, and most of the installation and fixing methods for the computer function expansion card in the industry at present are fixing schemes such as semicircular rotation pressing fixing and screw extension. The structure of the proposal has large volume and high development cost, and has certain limitation on the height and the size of the PCB part of the board card.
Disclosure of Invention
In view of the above problems, the present invention is directed to a computer expansion board clamping and fastening device with simple and compact structure, low cost and stable use.
In order to realize the technical purpose, the scheme of the invention is as follows: a computer expansion board clamping and fixing device comprises a body serving as a supporting structural member of the whole device, a transverse moving mechanism and a pressing plate mechanism; the transverse moving mechanism consists of a pushing screw rod arranged on the body and a sliding block, wherein the threaded sleeve can move along the axial direction of the screw rod along with the rotation of the screw rod on the screw rod, and the screwing end of the pushing screw rod is arranged at the outer side end of the body; the pressing plate mechanism consists of a pressing plate which can rotate around a positioning shaft fixed on the body and a pressing plate rebound spring; the slider is arranged close to the inner side face of the pressing plate, one end, close to the positioning shaft, of the inner side face is of a wedge-shaped structure, and the slider moves to be switched into the pressing plate to open and close through the wedge-shaped structure.
For more convenient use, the transverse moving mechanism and the corresponding pressing plate mechanism are arranged on the body in more than one group in a horizontal distribution manner.
For the smooth transition of pushing down, the end part of the pressing plate far away from the positioning shaft is of an arc-shaped structure.
As a further improvement, the device also comprises a cover body which is arranged on the body in a covering mode.
The press-fixing device has low development and manufacturing cost; the assembly and use are simple, the structure is compact, and the internal space of the whole machine is greatly saved; the pressing and fixing of the expansion board card are more stable when the expansion board card is used; the integrated circuit board fixing device can simultaneously fix various integrated circuit boards with different dimensions inside a case.

Detailed Description
The invention is described in further detail below with reference to the figures and specific embodiments.
As shown in FIG. 1, the present invention relates to a computer expansion board clamping and fastening device, which comprises a body 2 as a supporting structure of the whole device, a transverse moving mechanism and a pressing plate mechanism; wherein:
the transverse moving mechanism consists of a pushing screw rod 4 arranged on the body 2 and a slide block 3 which is sleeved on the screw rod 4 and can move along the axial direction of the screw rod along with the rotation of the screw rod, and the screwing end of the pushing screw rod 4 is arranged at the outer side end of the body; the front and back movement of the sliding block is realized by screwing the screw rod to rotate left and right.
The pressing plate mechanism consists of a pressing plate 5 which can rotate around a positioning shaft 6 fixed on the body and a pressing plate rebound spring 7; the platen rebound spring 7 ensures that the platen retracts towards the position of the body without the action of external forces.
The slider 3 is hugged closely the medial surface setting of clamp plate 5, and the one end that this medial surface is close to the location axle sets up to the wedge structure, and the removal of slider 3 converts opening and shutting of clamp plate 5 into through this wedge structure.
The transverse moving mechanism and the corresponding pressing plate mechanisms are more than one group and are horizontally distributed and installed on the body, and a plurality of groups of pressing plate mechanisms can be arranged on one body.
In the specific embodiment, the end of the pressing plate 5 far from the positioning shaft 6 is in an arc-shaped structure, and the body 2 is further provided with a cover body 1 which is covered on the body.
During specific use, twist and promote screw rod 4 and by keeping away from the gradual drawing-in of location axle 6 with slider 3, the slider is at the in-process that removes, gives the wedge structure application of force of survey face in the clamp plate 5, makes the clamp plate overcome clamp plate rebound spring 7's elasticity and around location axle 6 external rotation, does the expansion action of keeping away from body 2, see fig. 2 and 3, the clamp plate also from this presses to the extension integrated circuit board that needs the pressure to be fixed, realizes the stable fixed of extension integrated circuit board.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any minor modifications, equivalent replacements and improvements made to the above embodiment according to the technical spirit of the present invention should be included in the protection scope of the technical solution of the present invention.
