The term "and / or" used in the specification of the present utility model includes any and all combinations of one or more related listed items.

[0030] Combine the following Figure 1-Figure 4 The utility model describes a special sealing device for electric vehicle license plate.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, a special sealing device for an electric vehicle license plate includes a cap portion 100 , a rod portion 200 , a fastening ring 300 , and a protective ring 400 .

[0032] The rod portion 200 has threads.

[0033] The cap 100 is fixed to one end of the rod 200 . The cap 100 has a smooth surface and is provided with a screwdriver slot 130 . The screwdriver slot 130 is in a cross shape, a plum blossom shape, or a straight line shape.

[0034] The fastening ring 300 has a spiral groove 320 , an annular groove 330 and a threaded hole 310 which is interference fit with the rod 200 . The starting end of the spiral groove 320 is connected to the annular groove 330 , and the spiral direction of the spiral groove 320 is consistent with the locking direction of the rod 200 .

[0035] The protection ring 400 is sleeved on the outer wall of the fastening ring 300 , and the inner wall of the protection ring 400 has a sliding member 410 .

[0036] When the rod 200 and the license plate are locked by the fastening ring 300 , the slide 410 abuts against the terminal end of the spiral groove 320 . After the locking is completed, the slide 410 moves from the spiral groove 320 to the annular groove 330 .

[0037] When the electric vehicle license plate special sealing device is in use, the screwdriver is first clamped in the screwdriver groove 130, and then the cap 100 is rotated to make the rod 200 pass through the license plate and the mounting holes of the electric vehicle, and then the fastening ring 300 is used to fix the position of the license plate. During this process, the slide 410 always abuts against the terminal end of the spiral groove 320. After the position of the license plate is fixed, the protective ring 400 is rotated in the opposite direction to move the slide 410 from the spiral groove 320 to the annular groove 330. No matter which direction the protective ring 400 is rotated, the slide 410 always rotates in the annular groove 330, while the fastening ring 300 remains stationary. At the same time, if the rod 200 is rotated from one end of the cap 100, it is easy to make the fastening ring 300 rotate synchronously, so that it is difficult to remove the license plate of the electric vehicle, reducing the chance of theft and maintaining social order to a certain extent.

[0038] In this embodiment, the cap portion 100 has a first end portion 110 and a second end portion 120. The first end portion 110 is fixedly connected to the rod portion 200. The cross-sectional area of ​​the first end portion 110 gradually decreases toward the second end portion 120, further reducing the torsional stress point of the cap portion 100 and reducing the chance of the license plate being stolen.

[0039] In this embodiment, an elastic gasket 500 is sleeved on the outer wall of the rod portion 200 , and the elastic gasket 500 is located between the cap portion 100 and the fastening ring 300 . The elastic gasket 500 makes the license plate and the electric vehicle more tightly connected.

[0040] It should be supplemented that the size of the elastic gasket 500 is the same as the size of the first end portion 110 .

[0041] In this embodiment, the outer wall of the protective ring 400 has a plurality of bending corners 420 , and the bending corners 420 are arranged in a circular array with the axis of the protective ring 400 as the center. The bending corners 420 make it easier to install the license plate on the electric vehicle.

[0042] In this embodiment, a bending portion 340 is fixedly connected to the outer wall of the fastening ring 300, and the protective ring 400 is located between the bending portion 340 and the fastening ring 300. The bending portion 340 and the fastening ring 300 are perpendicular to each other, and the bending portion 340 and the protective ring 400 are in close contact with each other. The bending portion 340 can conveniently hide the difference between the fastening ring 300 and the protective ring 400, making the device more beautiful.

[0043] like Figure 3 and Figure 4 As shown, in one embodiment, a rubber block 430 is fixedly connected to the side wall of the slide 410, and the rubber block 430 is located on the side away from the terminal end of the spiral groove 320. Since the friction between the rubber block 430 and the fastening ring 300 is relatively large at the contact point, it can effectively prevent the slide 410 from automatically moving from the spiral groove 320 to the annular groove 330 during transportation.

[0044] In this embodiment, the rubber block 430 is slidably connected in the spiral groove 320 or the annular groove 330 .

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the attached claims.
