[0056] See Figures 1 to 7 , this embodiment provides a combined flat tire vehicle blocking roadblock, which includes a plurality of flat tire components 10, a coupling member 20 and a driving device 30. The flat tire component 10 includes a speed bump 11 and a flat tire puncture 12.

[0057] The speed bump 11 includes a seat body 111, an installation cavity 112 and a plurality of avoidance grooves 113. The installation cavity 112 is arranged inside the seat body 111. The plurality of avoidance grooves 113 are arranged on the top of the seat body 111 and communicate with the installation cavity 112.

[0058] The flat tire puncture 12 includes a rotating shaft 121 and a plurality of thorn plates 122. The rotating shaft 121 is rotatably arranged in the installation cavity 112, and a transmission groove 124 is respectively arranged at the two ends of the rotating shaft 121. The thorn plates 122 are arranged at intervals on the rotating shaft 121, corresponding to the avoidance grooves 113 one by one, and can pass through the avoidance grooves 113. The driving device 30 is used to drive the rotating shaft 121 to rotate.

[0059] The coupling member 20 is used to transmit and connect two adjacent rotating shafts 121. The coupling member 20 includes a main body portion 21 and two connecting blocks 22. A connecting block 22 is respectively arranged at both ends of the main body portion 21, and the two connecting blocks 22 are vertically arranged between them. The connecting block 22 can be placed in the transmission groove 124 and slide in the transmission groove 124.

[0060] In this embodiment, two adjacent rotating shafts 121 are connected by a connecting member 20. The connecting blocks 22 on the connecting member 20 slide in the transmission grooves 124 of the same-side rotating shafts 121, so that when the axes of the adjacent two rotating shafts 121 are offset, smooth force transmission can still be achieved between the adjacent two rotating shafts 121, thereby adapting to uneven road surfaces.

[0061] In one embodiment, the seat body 111 includes a bottom plate 114, two side plates 115, two inner support plates 116, a top plate 117, and two guiding inclined plates 118.

[0062] After the thorn plate 122 on the rotating shaft 121 rotates following the rotating shaft 121, one end of the thorn plate 122 abuts against the bottom plate 114, and the bottom plate 114 forms a support for it.

[0063] The two side plates 115 are symmetrically arranged and are respectively connected to both ends of the bottom plate 114. The two inner support plates 116 are arranged along the length direction of the bottom plate 114, the two inner support plates 116 are symmetrical to each other, the inner support plates 116 are connected to the upper end surface of the bottom plate 114, and both ends of the inner support plates 116 are respectively connected to the two side plates 115 on both sides.

[0064] The top plate 117 is detachably arranged on the two inner support plates 116 and the two side plates 115. An avoidance groove 113 is formed on the top plate 117, and the top plate 117 can be detachably connected to the upper ends of the inner support plates 116 by screws. The two guiding inclined plates 118 are symmetrically arranged on both sides of the top plate 117, and the guiding inclined plates 118 are simultaneously connected to the two side plates 115, the inner support plates 116, and the bottom plate 114. The top plate 117, the two side plates 115, and the two inner support plates 116 enclose an installation cavity 112, and the installation cavity 112 is in the shape of a cuboid.

[0065] In this embodiment, the top plate 117 is detachable, which facilitates subsequent maintenance and repair of the inside of the installation cavity 112.

[0066] In one embodiment, a U-shaped installation groove 119 is formed on the side plate 115. Both ends of the rotating shaft 121 are respectively located in the corresponding U-shaped installation grooves 119.

[0067] In this embodiment, the U-shaped installation groove 119 facilitates the installation of the rotating shaft 121. After the end of the rotating shaft 121 is placed in the U-shaped installation groove 119, the end of the rotating shaft 121 can block the U-shaped installation groove 119 to prevent foreign objects from entering.

[0068] In one embodiment, both ends of the guiding inclined plate 118 extend to the outside of the side plate 115, so that after two adjacent tire-breaking assemblies 10 are butted, the corresponding two guiding inclined surfaces are butted against each other, and a space for accommodating the connecting member 20 is formed between the two adjacent side plates 115.

[0069] In one embodiment, a plurality of reinforcing ribs 123 are further provided on the rotating shaft 121. The reinforcing ribs 123 are connected to the corresponding thorn plates 122. Specifically, the thorn plates 122 are connected to the outer wall of the rotating shaft 121, and the reinforcing ribs 123 are provided at the included angle position between the thorn plates 122 and the rotating shaft 121.

[0070] In this embodiment, when the rotating shaft 121 rotates, one end of the thorn plate 122 abuts against the bottom plate 114. The other end of the thorn plate 122 is a tip. At this time, the tip of the thorn plate 122 passes through the avoidance groove 113 and is used to puncture the tire. The thorn plate 122 needs to bear a large external force, and the reinforcing ribs 123 can enhance the connection between the thorn plate 122 and the rotating shaft 121.

[0071] In one embodiment, the cross-section of the avoidance groove 113 is triangular; the cross-section of the thorn plate 122 is triangular; the thorn plate 122 can form a blockage for the avoidance groove 113 in the installation cavity 112. Specifically, the thorn plate 122 is located at the lower end of the avoidance groove 113, and the size of the thorn plate 122 fits the size of the avoidance groove 113. When the thorn plate 122 rotates following the rotating shaft 121, the tip of the thorn plate 122 extends out of the avoidance groove 113.

[0072] In one embodiment, the driving device 30 includes a box body 31, an external connecting shaft 32, a transmission mechanism 33, and a motor (not shown).

[0073] The external connecting shaft 32 is rotatably arranged in the box body 31. One end of the external connecting shaft 32 can be connected to the corresponding rotating shaft 121. Specifically, the external connecting shaft 32 can also be connected to the rotating shaft 121 in the manner of the connecting member 20. The transmission mechanism 33 is arranged in the box body 31. The motor drives the external connecting shaft 32 to rotate through the transmission mechanism 33. The transmission mechanism 33 can be a gear box in the prior art.

[0074] In this embodiment, compared with the traditional pneumatic driving device 30, this roadblock is driven by a motor, and the structure is simplified.

[0075] The driving device 30 further includes a handle 34. The handle 34 is located in the box body 31. The handle 34 can drive the external connecting shaft 32 to rotate through the transmission mechanism 33. The handle 34 is coaxially connected to a certain gear in the transmission mechanism 33 (gear box).

[0076] In this embodiment, when a power outage occurs, the handle 34 can also be manually driven. The rotation of the handle drives the rotating shaft 121 to rotate through the transmission mechanism 33, so as to realize the extension of the thorn plate 122 from the avoidance groove 113 or the retraction of the thorn plate 122 from outside the avoidance groove 113.

[0077] In the description of the present utility model, a large number of specific details are set forth. However, it can be understood that the embodiments of the present utility model can be practiced without these specific details. In some instances, well-known methods, structures, and technologies are not shown in detail so as not to obscure the understanding of this specification.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
