The term "and / or" used in the description of the present utility model includes any and all combinations of one or more of the related listed items.
[0029] The following Figures 1 - 4 describes the anti-theft sealing device for an electric vehicle license plate of the present utility model.
[0030] As Figure 2 , Figure 3 and Figure 4 shown, in one embodiment, an anti-theft sealing device for an electric vehicle license plate includes a rod portion 100, a cap portion 200, a fastening ring 300, and an anti-theft ring 500.
[0031] The rod portion 100 has a smooth section 110 and a threaded section 120.
[0032] The cap portion 200 is fixedly connected to the free end of the smooth section 110, and the cap portion 200 has a first card slot 230, a screwdriver slot 250, and a cap 240. The first card slot 230 communicates with the screwdriver slot 250, the cap 240 is snap-fitted in the first card slot 230, and the screwdriver slot 250 is a cross slot or a plum blossom slot or a flat slot.
[0033] The fastening ring 300 is sleeved on the outer wall of the rod portion 100. The fastening ring 300 has a first groove 350, a circular ring groove 360, and a threaded hole 310 that is in threaded engagement with the threaded section 120. The first groove 350 communicates with the circular ring groove 360. One side of the first groove 350 has a second right-angled surface 352, and the other side of the first groove 350 has an inclined surface 351. The second right-angled surface 352 is in the same locking direction as the rod portion 100.
[0034] The anti-theft ring 500 is sleeved on the outer wall of the fastening ring 300. The inner wall of the anti-theft ring 500 has a second groove 510, a clamping post 530, and a spring 520. The spring 520 is fixed in the second groove 510. The clamping post 530 is fixed at the free end of the spring 520. The clamping post 530 abuts against the second right-angled surface 352.
[0035] When the anti-theft sealing device of the electric vehicle license plate is in use, a screwdriver is clamped in the screwdriver groove 250, and then the cap portion 200 is rotated to make the rod portion 100 penetrate through the mounting hole of the electric vehicle license plate. Finally, the fastening ring 300 is tightened on the outer wall of the rod portion 100. During the process of tightening the fastening ring 300 as required, the clamping post 530 always abuts against the second right-angled surface 352, so as to facilitate driving the fastening ring 300 to rotate by rotating the anti-theft ring 500. After the position of the fastening ring 300 is fixed, when a thief rotates the anti-theft ring 500 in the reverse direction, under the action of the spring 520, the clamping post 530 moves from the first groove 350 to the circular ring groove 360, and a relative rotation occurs between the anti-theft ring 500 and the fastening ring 300, so that the anti-theft ring 500 can only be tightened and cannot be removed from the rod portion 100, which increases the difficulty of disassembly, can play an anti-theft role to a certain extent, reduces the probability of license plate theft, maintains social order, and at the same time reduces the losses of users.
[0036] In this embodiment, a protrusion 320 is fixedly connected to the outer wall of the anti-theft ring 500. One side of the protrusion 320 has an arc surface 330. The arc surface 330 is tangent to the outer wall of the fastening ring 300. A locking angle 340 is formed between the other side of the protrusion 320 and the fastening ring 300. The locking angle 340 is an acute angle and is in the same locking direction as the threaded section 120. The locking angle 340 can provide a force application point during the process of tightening the fastening ring 300, making the installation more labor-saving. Since the arc surface 330 is tangent to the outer wall of the fastening ring 300, it is difficult to form a force application point during disassembly, thus increasing the difficulty of disassembly and improving the anti-theft effect.
[0037] In this embodiment, the protrusion 320 has a third end portion 321 and a fourth end portion 322. The cross-sectional area of the third end portion 321 gradually decreases in the direction of the fourth end portion 322, and a tip is formed at the fourth end portion 322. The protrusion 320 is perpendicular to the rod portion 100, reducing the force application point for reverse disassembly on the protrusion 320 and further improving the anti-theft effect.
[0038] As Figure 1 shown, in one embodiment, since traditional theft methods usually involve stuffing a cloth strip between the cap portion 200 and the license plate, and then twisting the rod portion 100 by rotating the cloth strip, to further improve the anti-theft effect, the surface of the cap portion 200 is smooth, and the cap portion 200 has a first end portion 210 and a second end portion 220. The first end portion 210 is located at one end away from the smooth section 110, and the cross-sectional area of the first end portion 210 gradually decreases towards the second end portion 220.
[0039] It should be added that an elastic gasket 400 is provided between the cap portion 200 and the fastening ring 300. The elastic gasket 400 is sleeved on the outer wall of the rod portion 100, and the size of the elastic gasket 400 is the same as that of the second end portion 220.
[0040] On the one hand, since the elastic gasket 400 is located between the cap portion 200 and the license plate, it is difficult for the cloth strip to be stuck between the cap portion 200 and the license plate. On the other hand, since the cross-sectional area of the first end portion 210 gradually decreases towards the second end portion 220, and the size of the elastic gasket 400 is the same as that of the second end portion 220, even if the cloth strip is stuck between the cap portion 200 and the license plate, it is difficult to apply a torque force to the rod portion 100, further improving the anti-theft effect.
[0041] In this embodiment, the first card slot 230 and the cap 240 are both located on the first end portion 210. The surface of the cap 240 is flush with the first end portion 210. The cap portion 200 has a second card slot 260. Elastic support plates 270 are symmetrically and fixedly connected to the bottom of the cap 240, and the elastic support plates 270 are snapped into the second card slot 260.
[0042] After the anti-theft sealing device finishes fixing the license plate to the electric vehicle, press the elastic support plates 270 on both sides to snap the cap 240 into the first card slot 230. At this time, the elastic support plates 270 are exactly snapped into the second card slot 260, and the surface of the cap 240 is flush with the first end portion 210, facilitating the blocking of the screwdriver slot 250 and further improving the anti-theft effect.
[0043] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0044] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the appended claims.
