[0007] By adopting the above technical solution, when the corresponding USB interface is not in use, the baffle will cover it, thereby reducing dust entry and increasing the use effect.

[0008] Preferably, a bending portion is provided at the other end of the torsion spring, and an outer wall of the bending portion is in contact with the bottom of the baffle.

[0009] By adopting the above technical solution, the use effect is increased.

[0010] Preferably, a threaded mounting sleeve is also provided on the inner side of the mounting block.

[0011] By adopting the above technical solution, the mounting block can be installed at the corresponding position.

[0012] Preferably, the positioning frame is clamped on the inner side of the mounting block.

[0013] By adopting the above technical solution, disassembly and assembly can be carried out.

[0014] In summary, the present application has the following beneficial technical effects: by setting a baffle, the plug interface can be blocked when the USB interface is not in use to reduce the entry of dust, and by setting a torsion spring, the baffle can be well reset to increase its use effect.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The following is combined with Figure 1-5 This application is described in further detail.

[0025] Reference Figure 1-Figure 4 , a dustproof device for a vehicle-mounted USB charging port, comprising a mounting block 1, two groups of plug-in slots are opened on the mounting block 1, a baffle 2 is further arranged on the mounting block 1 and located at the positions of the two groups of plug-in slots, a dial block 3 is arranged on the outer side of the baffle 2, by pressing the dial block 3 downward, the baffle 2 can be lowered, and then the USB connector can be inserted, when the USB interface is not needed, the baffle 2 blocks the plug-in slot to reduce the entry of dust, a positioning frame 4 is arranged on the back side of the mounting block 1, the baffle 2 is slidably connected to the inside of the positioning frame 4, a mounting column 7 is fixedly connected to the bottom of one side of the positioning frame 4, a torsion spring 6 is sleeved on the mounting column 7, one end of the torsion spring 6 abuts against the bottom of the positioning frame 4, and the other end of the torsion spring 6 contacts the bottom of the baffle 2.

[0026] Reference Figure 5 The other end of the torsion spring 6 is provided with a bending portion 8, and the outer wall of the bending portion of the bending portion 8 is in contact with the bottom of the baffle 2, which can increase its use effect.

[0027] Reference Figure 2 A threaded mounting sleeve 5 is also provided on the inner side of the mounting block 1 , and the positioning frame 4 is clamped on the inner side of the mounting block 1 .

[0028] The implementation principle of this embodiment is: when the USB interface needs to be used, the dial block 3 is toggled so that the blocking piece 2 enters the interior of the positioning frame 4, exposing the plug-in slot, and then the USB connector is plugged in. At this time, the USB connector prevents the blocking piece 2 from being reset. When the USB interface is not in use, the blocking piece 2 is reset under the action of the torsion spring 6, which can shield the plug-in slot, reduce dust from entering the interior from the plug-in slot, and increase its dust-proof effect.
