Description

Technical Field

[0001] The utility model relates to the technical field of image acquisition cards, in particular to an image acquisition card for anti-misalignment installation. Background Art

[0002] A frame grabber, also known as an image capture card, is a hardware device that captures, stores, and plays back digitized video information. Many frame grabbers can also capture audio simultaneously with the video, allowing the audio and video components to be stored and played back simultaneously during digitization. A PCI frame grabber generally consists of a baffle and a board.

[0003] For example, the application number is 202021049806.7, which is an image acquisition card that is easy to disassemble and assemble. The utility model describes an image acquisition card that is easy to disassemble and assemble. By adding a connecting block to the right side of the image acquisition card, the connection plate on the left side of the image acquisition card is used to fix the acquisition card from two positions on the left and right, thereby improving the stability of the acquisition card and better protecting the signal transmission of the gold finger. At the same time, a tightening knob with a threaded rod is used to fix the acquisition board, and the knob is elastically locked by a locking spring. On the one hand, there is no need to use a special screwdriver for disassembly, and on the other hand, the locking effect is improved. However, after analyzing the above-mentioned comparative patents and most existing PCI image acquisition cards, it was found that the connection plate and the plate body of most PCI acquisition cards are connected and fixed by two screws and screw holes. If the distribution of the connectors is symmetrical up and down, it is easy to cause the connection plate to be installed upside down, affecting the next step of installation.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an image acquisition card with anti-misalignment installation is proposed. Utility Model Content

[0009] Preferably, a limiting sliding groove is provided inside the square hole plate, and the outer surface of the disassembly rod is fixedly connected to a limiting sliding block.

[0010] Preferably, a heat dissipation fan is provided in the middle of the front surface of the plate body, and through holes are provided on the four outer surfaces of the heat dissipation fan that are connected to the front surface.

[0011] Preferably, a circular groove is formed on the front surface of the heat dissipation fan and extends to the interior of the through hole. A filter is provided inside the circular groove, and a screw hole plate is fixedly connected to the ring position of the filter.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a plate body, a circular joint, a gold finger, a circular hole, a square hole, a mounting mechanism, a baffle, a screw hole position, a circular hole plate, a square hole plate, a self-locking mechanism, a socket, a self-locking spring, a tapered block, a locking block, and a disassembly rod. When the plate body is installed on the baffle, the circular joint can be first inserted into the preset hole on the baffle, and then the square hole is clamped on the socket. During the insertion process, the locking block is retracted into the socket, squeezing the tapered block and the self-locking spring. After the self-locking spring is reset, the tapered block pushes out the locking block to lock the plate body. The circular hole plate and the plate body are then fixed by screws and the circular hole. When disassembling the square hole, the disassembly rod is pressed hard into the inside of the socket to retract the locking block into the inside of the socket. This design can distinguish the upper and lower installation positions when installing the baffle, and prevent the circular joints from being symmetrically distributed up and down, which leads to upper and lower misaligned installation.

The through-hole ensures the amount of air entering and improves the heat dissipation efficiency. The filter screen inside the circular groove can be disassembled for easy cleaning operation.
