Description

Technical Field

[0001] This invention relates to the field of computer technology, specifically to a dust cover structure for a computer external interface. Background Technology

[0002] A computer, commonly known as a PC, is one of the most advanced scientific and technological inventions of the 20th century. It is a modern intelligent electronic device capable of running programs and automatically and rapidly processing massive amounts of data. It consists of a hardware system and a software system. A computer without software installed is called a bare machine. Computers can be classified into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers. Cutting-edge fields include biological computers, photonic computers, and quantum computers.

[0003] According to Chinese announcement number CN219696778U, a computer interface card slot is disclosed, relating to the field of computer interface technology. The device features a dust cover rotatably hinged to the outer side of the computer interface body near the slot. A buckle is fixedly mounted on the outer side of the dust cover. A locking block is fixedly mounted on the outer side of the computer interface body near the dust cover. A handle is fixedly mounted on the side of the dust cover near the buckle. When the computer interface body is not in use, the dust cover is secured in the locking block via the buckle, thus protecting the slot from dust accumulation caused by prolonged exposure to the outside. This achieves the purpose of protecting the computer interface body.

[0004] The aforementioned existing computer interface card slot has the following drawbacks: the device only uses a dust cover to protect the computer body from dust when the plug is detached from the computer body, and cannot protect the computer body from dust when the plug is inserted into the computer body, thus limiting its dust protection and making it impractical. Summary of the Invention

[0005] The purpose of this invention is to provide a dust cover structure for a computer external interface to solve the technical problems affecting the stability of detection mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The device of the present invention uses a dustproof net, which enables air circulation at the connection point, preventing short circuits caused by excessive heat, and effectively improving the protection and safety of the connection between the plug and the computer body by preventing dust. The dustproof net is designed as two pieces, forming a connection hole when they abut. The plug power cord is tightly fitted into the connection hole, thereby preventing the plug from easily detaching from the computer body due to external pulling, improving the stability between the plug and the computer body, and preventing dust from entering the connection between the plug and the computer body, effectively playing a dustproof role. The two dustproof nets can move relative to each other with the help of the dustproof frame and the first sliding plate, facilitating the insertion and removal of the plug. The limiting and rebounding component can limit the outward movement distance of the dustproof net, and after the external force is removed, it rebounds to the abutting state, thereby providing a real-time dustproof effect and achieving the objectives of the present invention.

[0007] This invention discloses a dust cover structure for a computer external interface, including a connecting assembly, a dustproof component, and a limiting and rebounding component. The connecting assembly includes a mounting plate and bolts threaded into the computer body, with a through hole at the center of the mounting plate. The dustproof component includes a dustproof frame, two dustproof nets, and two first sliding plates. The protective frame is a square tube structure with longitudinal grooves and transverse sliding openings that communicate with the inner cavity of the protective frame on its upper and lower side walls. The grooves and sliding openings are connected to form a T-shaped structure. The inner ends of the two dustproof nets each have semi-circular through holes, which, after contact, form connection holes for sliding plug power cords. The outer ends of the two dustproof nets are respectively fixedly mounted with first sliding plates, and the outer ends of the two first sliding plates are respectively slidably fitted into the upper and lower sliding openings of the protective frame. The protective frame is fixed to the outer side of the mounting plate, and the center holes of the two are connected. The limiting and rebounding component is used to limit the outward movement distance of the dustproof nets and the first sliding plates, and to apply a rebound force to the outwardly moved dustproof nets and first sliding plates. After the tension is removed, the two dustproof nets can quickly return to the contact state.

[0008] Preferably, the limiting and rebounding component includes a spring, a second sliding plate, and a limiting rod; a limiting hole is provided near the outer end face of the first sliding plate; the limiting rod is structurally matched with the limiting hole; the spring and the limiting rod are respectively fixed to the left and right sides of the second sliding plate; there are two sets of limiting and rebounding components, with the limiting rods respectively sleeved in the upper and lower limiting holes of the first sliding plate, the spring and the second sliding plate respectively located in the upper and lower sliding grooves of the protective frame, and the other end of the spring is respectively fixed to the bottom wall of the upper and lower sliding grooves.

[0009] More preferably, the spring and the limiting rod are coaxially arranged.

[0010] Preferably, the outer end face of the first slide plate is provided with a force-applying structure to facilitate applying tension to the first slide plate.

[0011] More preferably, the force-applying structure is a tension plate.

[0012] Preferably, the mounting plate has an inverted U-shaped structure.

[0013] Preferably, the groove is located in the middle of the slide opening.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows: When the plug is inserted into the inner wall of the computer body, the two dustproof nets are in an abutting state, allowing one side of the dustproof net to tightly fit onto the surface of the plug's power cord, limiting one side of the plug and preventing it from easily detaching from the computer body due to external pulling, thus improving the stability between the plug and the computer body. Furthermore, the dustproof nets enhance the protection of the connection between the computer body and the plug, preventing dust from entering the connection point and affecting connection performance. The two dustproof nets can move relative to each other using the dustproof frame and the first sliding plate, facilitating plug insertion and removal. The limiting and rebounding component restricts the outward movement distance of the dustproof nets and rebounds to the abutting state after the external force is removed, thus providing real-time dustproof protection. In addition, this device, by setting up dustproof nets, allows air circulation at the connection point, preventing overheating and short circuits, effectively improving the protection and safety of the connection between the plug and the computer body.

The protective frame 4 is a square tubular structure with longitudinal grooves 5 and transverse sliding openings 6 on its upper and lower side walls, which communicate with the inner cavity of the protective frame 4. The grooves 5 are located in the middle of the sliding openings 6, and the two are connected to form a T-shaped structure. A pull plate 10 is provided at the center of the outer end face of the first sliding plate 14, and a limiting hole 11 is provided near the center of the outer end face. The dustproof net 12 consists of two pieces, with the inner end faces of the two dustproof nets 12 abutting each other.
