Description

Technical Field

[0001] This application relates to the field of computer component technology, specifically a dustproof and waterproof device for a computer interface. Background Technology

[0002] With the continuous development of computer technology, the USB interface, as one of the important interfaces for connecting computers to external devices, is becoming increasingly widely used. However, during use, USB interfaces are often exposed to the outside world and are easily affected by dust and water. This not only affects the normal use of the USB interface but may also cause damage and shorten its lifespan.

[0003] To address the aforementioned issues, a Chinese utility model patent (publication / announcement number CN213584359U) proposes a waterproof and dustproof device for a computer USB interface. This device, through the inclusion of a movable groove, side wall sealing groove, bottom sealing groove, sealing baffle, fixing groove, and fixing plate, achieves complete sealing of the USB interface when not in use, effectively preventing the intrusion of water and dust, thereby ensuring the safety of the USB interface and extending its service life.

[0004] However, despite its significant dust and water protection effectiveness, this dustproof device presents operational inconveniences in practical use. Specifically, the process of manually moving the connecting plate upwards to insert the external connector into the computer interface is relatively cumbersome and inconvenient for users. This can be particularly time-consuming and inefficient in urgent situations or when rapid connection to external devices is required.

[0005] Therefore, this application provides a dustproof and waterproof device for a computer interface to solve the above problems. Utility Model Content

[0006] This application provides a dustproof and waterproof device for a computer interface, aiming to solve the problems mentioned in the background art, such as the need to manually move the connecting plate upwards to insert the external connector into the computer interface during use, which is a relatively cumbersome operation and causes inconvenience to users.

[0007] To achieve the above objectives, this application provides the following technical solution: a computer interface dustproof and waterproof device, comprising a computer interface and a shielding structure for dustproofing and waterproofing the computer interface;

[0008] The shielding structure includes a positioning plate fixedly mounted on the computer interface, a through-hole on the positioning plate corresponding to the computer interface, a fixed plate fixedly mounted on the positioning plate at the end away from the computer interface and above the through-hole, a shielding plate movably latched onto the bottom of the fixed plate to shield the through-hole, and an elastic element disposed within the shielding plate to drive the shielding plate to move closer to the fixed plate. When the computer interface is not in use: the elastic element is in its natural state, driving the shielding plate to fit tightly against the fixed plate, forming a sealed structure to prevent dust and water from entering the computer interface. When the computer interface is in use: the user moves the shielding plate downwards, causing the elastic element to be compressed and hold force. At this time, the external connector can pass through the through-hole between the shielding plate and the fixed plate and be smoothly inserted into the computer interface. After insertion, the elastic element releases the stored force, pushing the shielding plate and the fixed plate to stably fit against the bottom and top of the external connector, forming a secondary sealing structure to prevent dust and water from entering the computer interface during use.

[0009] Preferably, to facilitate fixing the positioning plate to the computer interface: screws are inserted into both the top and bottom of the positioning plate, and the screws are threaded into the computer interface. By using the threaded connection between the screws and the computer interface, users can easily fix the positioning plate to the computer interface without complicated installation steps or tools, greatly improving the ease of installation.

[0010] Preferably, to improve the sealing performance between the positioning plate and the computer interface: a sealing ring is provided at one end of the positioning plate near the computer interface to seal the gap between the positioning plate and the computer interface. The sealing ring can fit tightly around the computer interface, effectively filling the tiny gap between the positioning plate and the computer interface, thereby preventing the infiltration of dust and moisture.

[0011] Preferably, the elastic element includes protective plates symmetrically inserted into the baffle plate, a limiting groove formed within the baffle plate, a limiting plate movably disposed within the limiting groove and fixedly connected to the lower end of the protective plate, and a spring fixedly disposed inside the limiting groove and between the limiting plate and the limiting groove. The addition of the protective plate and spring provides a more reliable driving and protection mechanism for the baffle plate. Even during the insertion and removal of the external connector, it effectively prevents the intrusion of dust and moisture, further improving the dustproof and waterproof effect.

[0012] Preferably, to prevent the spring from deforming under compression: a guide rod is slidably inserted into the limiting plate and fixedly connected to the limiting groove, and the spring is fitted onto the guide rod. Adding the guide rod effectively prevents unnecessary deformation or displacement of the spring under compression. This ensures that the spring maintains a stable axial force during deformation, thereby improving the reliability and stability of the baffle's movement.

[0013] Preferably, to facilitate the insertion of the external connector into the computer interface: both the fixing plate and the shielding plate have beveled edges at the ends away from the positioning plate, and the two beveled edges form a wide-mouth groove. By adding the beveled edges and the wide-mouth groove, the ease of insertion of the external connector is improved. Users do not need to laboriously adjust the angle or position of the external connector; they can easily complete the insertion operation by simply pushing it gently along the direction of the beveled edges.

[0014] This application, through its shielding structure, effectively prevents dust and water from entering the computer interface, whether it is in use or not, ensuring the interface's safety and stability. When using the computer interface, users simply need to move the shield downwards to easily insert the external connector, making the operation simple and quick. The combination of the shielding structure and the elastic element effectively extends the lifespan of the computer interface and reduces damage caused by dust and water intrusion.

[0015] This application improves the ease of connection of the external connector by adding a bevel and a wide slot. Users do not need to laboriously adjust the angle or position of the external connector; they can easily complete the connection operation by simply pushing it gently along the bevel.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] This embodiment provides a dustproof and waterproof device for a computer interface, such as... Figure 1-6 As shown, the dustproof and waterproof device includes a computer interface 1 and a shielding structure 2 for dustproofing and waterproofing the computer interface 1.

[0026] The shielding structure 2 includes a positioning plate 21 fixedly mounted on the computer interface 1, a through-hole 22 on the positioning plate 21 corresponding to the computer interface 1, a fixing plate 23 fixedly mounted on the positioning plate 21 at the end away from the computer interface 1 and above the through-hole 22, a shielding plate 24 movably latched onto the bottom of the fixing plate 23 to shield the through-hole 22, and an elastic element 25 disposed within the shielding plate 24 to drive the shielding plate 24 to move closer to the fixing plate 23. Through the shielding structure 2, dust and water can be effectively prevented from entering the computer interface 1 when it is in use or not, ensuring the safety and stability of the interface. When using the computer interface 1, the user only needs to move the shielding plate 24 downwards to easily plug the external connector into the interface, making the operation simple and quick. The cooperation of the shielding structure 2 and the elastic element 25 effectively extends the service life of the computer interface 1 and reduces interface damage caused by dust and water intrusion. When the computer interface 1 is not in use: the elastic element 25 is in its natural state, driving the shield 24 to fit tightly against the fixed plate 23, forming a sealed structure to prevent dust and water from entering the computer interface 1. When the computer interface 1 is in use: the user moves the shield 24 downwards, causing the elastic element 25 to be compressed and store force. At this time, the external connector can pass through the opening 22 between the shield 24 and the fixed plate 23 and be smoothly inserted into the computer interface 1. After insertion, the elastic element 25 releases the stored force, pushing the shield 24 and the fixed plate 23 to fit stably against the bottom and top of the external connector, forming a secondary sealing structure to prevent dust and water from entering the computer interface 1 during use.

[0027] Specifically, to facilitate fixing the positioning plate 21 to the computer interface 1, screws 211 are inserted into both the top and bottom of the positioning plate 21, and the screws 211 are threaded into the computer interface 1. Through the threaded connection of the screws 211 to the computer interface 1, users can easily fix the positioning plate 21 to the computer interface 1 without complicated installation steps or tools, greatly improving the ease of installation. The tightening effect of the screws 211 makes the connection between the positioning plate 21 and the computer interface 1 more secure, effectively preventing loosening or detachment due to external forces or long-term use, thereby ensuring the overall stability and dustproof and waterproof effect of the shielding structure 2. This screw 211 fixing method is applicable to various types and specifications of computer interfaces 1, has good versatility and compatibility, and enables the invention to be widely used in various computers and electronic devices.

[0028] To improve the sealing performance between the positioning plate 21 and the computer interface 1, a sealing ring 212 is provided at the end of the positioning plate 21 near the computer interface 1 to seal the gap between the positioning plate 21 and the computer interface 1. The sealing ring 212 can fit tightly around the computer interface 1, effectively filling the tiny gap between the positioning plate 21 and the computer interface 1, thereby preventing the infiltration of dust and moisture. The sealing ring 212 is made of elastic material; silicone and rubber materials have good sealing performance and aging resistance.

[0029] Specifically, the elastic element 25 includes a protective plate 251 symmetrically inserted into the baffle plate 24, a limiting groove 252 formed within the baffle plate 24, a limiting plate 253 movably disposed within the limiting groove 252 and fixedly connected to the lower end of the protective plate 251, and a spring 254 fixedly disposed inside the limiting groove 252 and between the limiting plate 253 and the limiting plate 253. The addition of the protective plate 251 and spring 254 provides a more reliable driving and protection mechanism for the baffle plate 24. Even during the insertion and removal of the external connector, it effectively prevents the intrusion of dust and moisture, further improving the dustproof and waterproof effect. The elastic force of the spring 254 ensures that the baffle plate 24 remains firmly attached to the bottom of the external connector or the fixed plate 23, forming a tight seal. This design not only improves the sealing performance but also enhances the overall stability of the baffle structure 2. Users can easily insert and remove the external connector by simply moving the baffle plate 24 up and down, without additional tools or steps, greatly improving the ease of operation. When it is necessary to insert the external connector, the user moves the baffle plate 24 downwards. During this process, the baffle 24 compresses the spring 254 towards the limit plate 253 via the limiting groove 252, causing the spring 254 to deform and store energy. Simultaneously, the baffle 24 moves the limiting groove 252 downwards along the protective plate 251, which remains on both sides of the opening 22 to prevent dust and moisture intrusion. As the baffle 24 moves downwards, the external connector passes through the gap between the baffle 24 and the fixing plate 23 into the opening 22 and is successfully inserted into the computer interface 1. At this time, due to the elastic force of the spring 254, the baffle 24 adheres tightly to the bottom of the external connector, while the fixing plate 23 adheres tightly to the top of the external connector, forming a tight seal that effectively prevents dust and moisture intrusion. When the external connector is pulled out, the spring 254 releases its stored energy, pushing the limit plate 253 and the protective plate 251 upwards along with the baffle 24 until the baffle 24 re-adheres tightly against the fixing plate 23, restoring the original dustproof and waterproof state.

[0030] More specifically, to prevent the spring 254 from deforming under compression, a guide rod 2541, which is fixedly connected to the limiting groove 252, is slidably inserted into the limiting plate 253, and the spring 254 is fitted onto the guide rod 2541. The addition of the guide rod 2541 effectively prevents unnecessary deformation or displacement of the spring 254 under compression. This ensures that the spring 254 maintains a stable axial force during deformation, thereby improving the reliability and stability of the movement of the baffle plate 24. During the downward movement of the baffle plate 24, the limiting plate 253 slides along the guide rod 2541 and compresses the spring 254. Due to the limiting effect of the guide rod 2541, the spring 254 can only deform in the axial direction of the guide rod 2541, thus avoiding unnecessary displacement or twisting of the spring 254 under compression.

[0031] Furthermore, to facilitate the insertion of the external connector into the computer interface 1, both the fixing plate 23 and the shielding plate 24 have beveled edges 3 at their ends away from the positioning plate 21, forming a wide-mouth groove 31. The addition of the beveled edges 3 and the wide-mouth groove 31 improves the ease of insertion of the external connector. Users do not need to laboriously adjust the angle or position of the external connector; they can easily complete the insertion operation by simply pushing it gently along the direction of the beveled edge 3. Even during the insertion and removal of the external connector, the sealing performance of the opening 22 is maintained due to the synergistic effect of the shielding plate 24 and the protective plate 251. This effectively prevents the intrusion of dust and moisture, further extending the service life of the computer interface 1. Due to the ease of insertion and the reliability of the sealing performance, users can enjoy a smoother and more reassuring operating experience when using this invention. This not only improves user work efficiency but also enhances user satisfaction and trust in the product. When it is necessary to insert the external connector, the user only needs to align the head of the external connector with the opening end of the wide-mouth groove 31 and push it inward along the direction of the beveled edge 3. Guided by the inclined side 3, the external connector can easily slide into the gap between the fixing plate 23 and the shield 24, gradually approaching the computer interface 1. As the external connector goes deeper, its head contacts the upper surface of the shield 24, pushing the shield 24 downward. During this process, the shield 24 compresses the spring 254. At the same time, the shield 24 drives the limiting groove 252 to move downward along the protective plate 251, which remains on both sides of the opening 22 to prevent dust and moisture from entering. When the external connector is fully inserted into the computer interface 1, the shield 24 will be pressed tightly against the bottom of the external connector by the elastic force of the spring 254, forming a tight seal with the fixing plate 23. When it is necessary to remove the external connector, the user only needs to gently pull the external connector outward. At this time, the shield 24 will automatically move upward by the elastic force of the spring 254 until it is tightly pressed against the fixing plate 23 again, restoring its original dustproof and waterproof state.
