The first support rod 2 and the second support rod 3 are supported by the guardrail 4. The guardrail 4 prevents the cargo from shifting or falling off during the driving of the vehicle, thereby ensuring road traffic safety.

[0033] A clamping assembly for supporting the guardrail 4 is installed on the first support rod 2 and the second support rod 3 , and an adjusting assembly for controlling whether the guardrail 4 can cooperate with the clamping assembly is provided on the guardrail 4 .

[0034] Among them, the clamping assembly includes a first slide groove 201 arranged on both sides of the first support rod 2, a plurality of first limit blocks 202 fixedly installed in the first slide groove 201, a second slide groove 301 arranged on one side of the second support rod 3, and a plurality of second limit blocks 302 fixedly installed in the second slide groove 301.

[0035] The adjustment assembly includes a first clamping block 401 fixedly mounted on one side of the guardrail 4, a connecting block 402 fixedly mounted on the other side of the guardrail 4, a connecting groove 403 provided in the connecting block 402, a second clamping block 404 slidably mounted in the connecting groove 403, and a driving assembly for driving the second clamping block 404 to slide in the connecting groove 403. The driving assembly includes a rack 405 fixedly mounted on the second clamping block 404, a gear 406 rotatably mounted in the connecting groove 403 and meshing with the rack 405, and a hand 408 fixedly mounted on the gear 406, and the hand 408 is located on the outer side of the connecting block 402.

[0036] The guardrail 4 can be installed on the first support rod 2 and the second support rod 3 by placing the first clamping block 401 between two adjacent second limit blocks 302 and placing the second clamping block 404 between two adjacent first limit blocks 202 and keeping the guardrail 4 in a horizontal state.

[0037] The installation process is as follows:

[0038] First, hold the guardrail 4, move the first clamping block 401 into the second slide slot 301, and combine the first clamping block 401 with the two adjacent second limit blocks 302;

[0039] Then move the guardrail 4 to a horizontal position, then turn the handle 408 to drive the gear 406 to rotate, and drive the rack 405 to rotate through the gear 406, thereby driving the second clamping block 404 to slide along the connecting groove 403, so that the second clamping block 404 moves into the first slide groove 201, and the second clamping block 404 is combined with the two adjacent first limit blocks 202, thereby completing the installation of the guardrail.

[0040] Furthermore, the guardrail can be installed at any position on the first support rod 2 and the second support rod 3, which is convenient for adjusting the number and density of the installed guardrails 4. For example, for large goods, fewer guardrails 4 can be installed to achieve a good fixing effect on the goods and reduce workload.

[0041] like Figure 6-7As shown, the anti-loosening assembly is also included, and the anti-loosening assembly prevents the gear 406 from rotating due to vibration.

A plurality of springs 502 are fixedly mounted on the telescopic rod 407, and the other end of the spring 502 is fixedly connected to the rotating handle 408. When the guardrail 4 is installed, the ratchet 5 can be driven to slide on the pawl 501 by rotating the handle 408. Under the action of the spring 502, a downward force can be applied to the handle 408, thereby preventing the handle 408 from moving upward when the vehicle is bumpy. When the handle 408 wants to rotate in the opposite direction when the vehicle is bumpy, the ratchet 5 will limit the pawl 501 to prevent the handle 408 from reversing. When the guardrail 4 needs to be reversed to dismantle the guardrail 4, the handle 408 is pulled upward, and the reversed handle 408 is transmitted through the telescopic rod 407 to remove the guardrail 4.

[0042] Working principle: First, move the first clamping block 401 into the second slide groove 301, and combine the first clamping block 401 with the two adjacent second limit blocks 302, then move the guardrail 4 to a horizontal position, then turn the handle 408 to drive the gear 406 to rotate, thereby driving the second clamping block 404 to slide along the connecting groove 403, so that the second clamping block 404 moves into the first slide groove 201, and combines the second clamping block 404 with the two adjacent first limit blocks 202, thereby completing the installation of the guardrail. When the guardrail 4 is installed When the vehicle is bumpy, the handle 408 wants to rotate in the opposite direction, the ratchet 501 will limit the position of the ratchet 501, and when the guardrail 4 needs to be removed by reversing the handle 408, the handle 408 is pulled upward, and the reversed handle 408 is transmitted through the telescopic rod 407 to remove the guardrail 4.
