[0030] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-Figure 6 As shown, a road blocking device includes a main body 1, and retractable road blocking frames 2 are arranged on both sides of the main body 1, and a plurality of levers 21 are arranged on the road blocking frame 2, each lever 21 is provided with a warning light 3, and the warning light 3 is wirelessly connected to the main body 1, and the warning light 3 has a built-in circuit board 31 and a power supply 32, and a lamp bead 33 is arranged on the circuit board 31.

[0032] At the same time, each gear lever 21 is provided with a hollow mounting column 28 on the side close to the main body 1, and a coil 26 is wound around the outside of the mounting column 28, and the power supply 32 is electrically connected to the circuit board 31 and the coil 26 respectively, and a detachable iron core 24 is provided on the road sealing frame 2, and one end of the iron core 24 is located in the main body 1 and is sleeved with a coil 27, and the other end of the iron core 24 passes through the mounting column 28 of each gear lever 21, and an alternating current or pulsed direct current is supplied to the coil 2 27 to generate a changing magnetic field, thereby allowing the coil 26 to generate current and charge the power supply 32.

[0033] Therefore, in actual use, through the setting of wireless connection, the signal reception between the warning light 3 and the main body 1 does not use wire connection. Secondly, by supplying alternating current or pulsed direct current to the coil 27 to generate a changing magnetic field, the coil 1 26 generates current and charges the power supply 32, so that the charging of the warning light 3 does not use wire connection, and the appearance will not be affected by the wire, and there will be no problems existing in the wire connection.

[0034] The specific principle of wireless charging is electromagnetic induction wireless charging, and this type of charging system is mainly composed of two coils, a primary coil and a secondary coil. By passing alternating current or pulsed direct current of a certain frequency through the primary coil, a certain current will be generated in the secondary coil due to the effect of electromagnetic induction, so energy begins to be transmitted and then charged.

[0035] Secondly, the lever 21 is provided with a mounting groove 29 at one side close to the main body 1 , and a hollow mounting column 28 is disposed in the mounting groove 29 .

[0036] Therefore, in actual use, the mounting column 28 is internally mounted and not exposed, thereby protecting the coil 1 26 .

[0037] like Figure 3 As shown, the structure of the iron core 24 is: first, the barrier rod 21 at one end of the road sealing frame 2 away from the main body 1 is the end barrier rod, and the iron core 24 includes an iron core 1 241 and an iron core 242, and the iron core 1 241 is U-shaped and includes two horizontal bars and a vertical bar, wherein the vertical bar is located in the main body 1 and is sleeved with a coil 27, and the horizontal bar passes through the main body 1 and is exposed so as to pass through the mounting column 28.

[0038] At the same time, one end of the second iron core 242 passes through the end stop rod and contacts the first iron core 241, and this end is separated from the first iron core 241 when the road closing frame 2 is unfolded, and the other end of the second iron core 242 is connected to the end stop rod.

[0039] Therefore, in actual use, the warning light 3 can only be charged when the road blocking frame 2 is retracted. In addition, a handle 23 is provided on the end lever away from the main body 1, and the other end of the iron core 242 abuts against the inner wall of the handle 23, wherein the setting of the handle 23 facilitates the extension and retraction of the road blocking frame 2.

[0040] like Figure 4 As shown, the connection between the lever 21 and the warning light 3 is that the lever 21 is provided with a placement slot 211, and the warning light 3 is located in the placement slot 211, and a fastener is used to connect the lever 21 and the warning light 3. The fastener is a screw.

[0041] Furthermore, the warning light 3 is provided with inclined plane 1 36 at both ends of the side close to the shift lever 21 , and the placement groove 211 is provided with inclined plane 212 corresponding to the inclined plane 1 36 , and the fastener passes through the inclined plane 1 36 and the inclined plane 212 .

[0042] Therefore, in actual use, the contact area is increased by setting the inclined surface, thereby making the connection more stable.

[0043] like Figure 1-Figure 6 As shown, the warning light 3 is provided with a plurality of grooves 37 on a side away from the shift lever 21 , and a protrusion 38 is provided between two adjacent grooves 37 .

[0044] Therefore, in actual use, the light emitted by the lamp bead 33 is reflected and refracted through the concave and convex settings, so that the light irradiation range is wider and the brightness is stronger.

[0045] like Figure 2 As shown, the structure of the road blocking frame 2: first, the road blocking frame 2 includes a plurality of telescopic components, and each telescopic component includes a stop rod 21 and two telescopic rods 22, and the two telescopic rods 22 are located at both ends of the stop rod 21, wherein two adjacent telescopic components are connected by the socket connection between the telescopic rods 22, and along the direction away from the main body 1, the diameter of the telescopic rod 22 of each telescopic component gradually decreases.

[0046] Therefore, in actual use, the diameter of the telescopic rod 22 closest to the main body 1 is the largest, and then the diameter is successively smaller, and the two adjacent telescopic rods 22 are relatively movable, thereby achieving telescopic movement.

[0047] Secondly, the telescopic structure of the road sealing frame 2 itself is a relatively common prior art, and reference may be made to the telescopic stairs and the utility model with patent number 2017216106486.

[0048] Moreover, the telescopic rod 22 closest to the main body 1 is connected to the main body 1 and has a section located inside the main body 1, and the section has a certain length. Therefore, in order to avoid interference from the road blocking frames 2 on both sides and minimize the length of the main body 1, the road blocking frames 2 on both sides of the main body 1 are not on the same longitudinal plane, that is, one is close to the front of the main body 1, and the other is close to the back of the main body 1.

[0049] like Figure 5 As shown, the main body 1 has a display screen 4 and a speaker 5 built therein, and a hole 11 is opened in the front of the main body 1 corresponding to the display screen 4, and a sound outlet hole 12 is opened in the front of the main body 1 corresponding to the speaker 5.

[0050] Therefore, in actual use, in addition to the warning of the warning light 3, the display screen 4 and the speaker 5 also provide auxiliary warnings.

[0051] The main body 1 includes a shell 13 and side panels 14 located at both sides of the shell 13 . The shell 13 is provided with a hole 11 and a sound outlet 12 , and the side panels 14 are provided with holes corresponding to the iron core 24 and the telescopic rod 22 .

[0052] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. At the same time, the utility model is not limited by the above embodiments, so without departing from the principle and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model claimed for protection.
