Description

Technical Field

[0001] The utility model relates to the technical field of computer external plug-in cards, in particular to a screw-free fixing device for a computer external plug-in card. Background Art

[0002] A computer add-in card (also called an expansion card or plug-in card) is a circuit board that can be inserted into a computer motherboard to expand its functions. These cards usually plug into the motherboard's expansion slot. The main functions of an add-in card are generally to enhance graphics processing capabilities, suitable for gaming and professional graphics processing, improve the quality of audio output and input, suitable for music production and high-quality audio playback, increase network connectivity, and be used to add additional storage devices. A computer add-in card with a screwless fixing device is a device that is firmly fixed to the expansion slot on the motherboard without the need for screws. The advantage of this device is that it simplifies the installation and removal process and improves user convenience.

[0003] Most existing plug-in cards are fastened to the computer chassis using screw attachments, which are usually secured with tools such as an electric screwdriver. Manual removal of the card is time-consuming and labor-intensive, and does not allow for quick access to the computer card. Furthermore, most devices are one-to-one and cannot accommodate cards of other sizes. Therefore, we propose a screw-free fixing device for computer plug-in cards. Utility Model Content

[0004] The purpose of the utility model is to provide a screw-free fixing device for a computer external card to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a screw-free fixing device for a computer external card, comprising a device main body, a clamping assembly installed in the device main body for fixing the external card, a card slot fixed in the device main body for placing the computer external card, the clamping assembly comprising two groups of fixed shafts symmetrically fixed in the device main body, the outer walls of the two groups of the fixed shafts are rotatably connected with a V-shaped turning rod, one end of the V-shaped turning rod is installed with a sliding assembly, the other end of the V-shaped turning rod is fixed with a rectangular splint, the outer wall of the rectangular splint is installed with a number of limit assemblies, the rectangular splint is fixed with a protective plate through the card slot, and the card slot is provided with a hole for the rectangular splint to pass through.

[0006] Furthermore, the sliding assembly includes a concave slider slidably arranged at the bottom of the inner wall of the device body, the concave slider is fixed with a rotating shaft, one end of the V-shaped rotating rod is rotatably connected to the rotating shaft, and two groups of first springs are symmetrically fixed at both ends of the concave slider, and the other end of the first spring is fixedly connected to the bottom of the inner wall of the device body.

[0007] Furthermore, the limiting assembly includes a plurality of pawls rotatably connected to the top of the rectangular clamping plate, a fixing plate is fixed near the pawls, a second spring is fixed to the front outer wall of the fixing plate, and the other end of the second spring is fixedly connected to the pawl.

[0008] Furthermore, the inner wall of the device body is symmetrically provided with four groups of rectangular slide grooves on both sides of the card slot, and rectangular sliders are slidably provided on the inner walls of the four groups of rectangular slide grooves. The two groups of rectangular sliders on the same side are fixed with bevel racks on their facing sides.

[0009] Furthermore, the bevel rack is adapted to the pawl, and a T-shaped pull rod is fixed on the facing side of the bevel rack.

[0010] Furthermore, the T-shaped pull rod passes through the device body, and a through slot for the T-shaped pull rod to pass through is provided on the top of the device body.

[0011] Compared with the prior art, the beneficial effect of the present invention is as follows: by setting the device main body, clamping components, etc., when in use, the device main body is fixed in the corresponding position, and then the external card is inserted into the card slot. When the external card is inserted, the concave slider will be squeezed, and two sets of V-shaped rotating rods are rotatably connected in the concave slider. When the concave slider slides to the left, it will drive the V-shaped rotating rod to rotate, so that the rectangular splint fixes the external card in the card slot. Several ratchets are fixed on the rectangular splint, and the ratchets engage with the bevel rack, so that the external card can be fixed. When you want to take out the external card, you push the T-shaped pull rod downward, and the T-shaped pull rod will drive the bevel rack to slide, thereby disengaging the engagement state. At this time, the external card pops out, and external cards of different sizes can be inserted into the card slot. Through the above design, the computer external card can be quickly fixed and removed, and it can adapt to the insertion of external cards of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS
