[0028] like Figures 1 to 5 As shown, a USB interface dustproof device includes a dust cover 1, a baffle 2 rotatably connected to one side of the dust cover 1, an insertion port with a size smaller than that of the baffle 2 in the center of the dust cover 1, a connecting frame 3 slidably connected to one side of the dust cover 1, a pressing plate 4 fixedly connected to one side of the connecting frame 3, an adhesive tape 5 fixedly connected to one side of the pressing plate 4, several springs 6 fixedly connected to one side of the pressing plate 4, and four limiting rods 7 rotatably connected to one side of the dust cover 1, the length of the limiting rods 7 being greater than the width of one side of the connecting frame 3.
[0029] A first groove is provided on one side of the dust cover 1. The inner surface of the first groove is adapted to the outer surface of the baffle 2. One side of the baffle 2 is rotatably connected to the inside of the first groove.
[0030] A second groove is provided on one side of the dust cover 1. The inner surface of the second groove is adapted to the outer surface of the connecting frame 3. One side of the connecting frame 3 is slidably connected to the inside of the second groove. In use, the connecting frame 3 moves downward, causing the pressing plate 4 to drive the adhesive tape 5 to move downward.
[0031] A third groove is provided on one side of the dust cover 1. The inner surface of the third groove is adapted to the outer surface of the pressing plate 4. The pressing plate 4 is slidably connected inside the third groove.
[0032] The outer surface of the adhesive tape 5 is adapted to the inner surface of the third groove. The adhesive tape 5 is slidably connected inside the third groove. Then, the limiting rod 7 is rotated so that the limiting rod 7 is inserted into the groove of the dust cover 1 to restrict the connecting frame 3.
[0033] The diameter and height of the spring 6 are smaller than the width and depth of the third groove, respectively. The spring 6 is fixedly connected inside the third groove. Due to the action of the spring 6, downward pressure is applied to the pressing plate 4 and the adhesive tape 5, so that the dust cover 1 is tightly bonded to the USB interface.
[0034] A fourth groove is provided on one side of the dust cover 1. The inner surface of the fourth groove is adapted to the outer surface of the limiting rod 7. One side of the limiting rod 7 is rotatably connected to the inside of the fourth groove.
[0035] A fifth groove is provided on one side of the connector 3. The inner surface of the fifth groove is adapted to the outer surface of one side of the limiting rod 7. One side of the limiting rod 7 is rotatably connected to the inside of the fifth groove. The baffle 2 is used to block the insertion port of the dust cover 1, thereby preventing dust from entering the interface and protecting the USB interface.
[0036] Compared with the prior art, the present invention has the following advantages:
[0037] The baffle 2 protects the insertion port of the dust cover 1, preventing dust from entering the USB interface and affecting the lifespan and communication performance of the USB. The elasticity of the spring 6 applies pressure to the pressing plate 4 and the adhesive tape 5, ensuring that the dust cover 1 is firmly attached to the USB interface, preventing the dust cover 1 from loosening, falling off, and losing its protective effect.
