[0022] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation manners of the utility model will be explained by referring to the drawings. In the drawings, the same components are marked with the same reference numerals.

Referring to Figures 1a to 5As shown, the utility model provides an open movable guardrail 100 that is easy to disassemble, which includes a plurality of guardrail segments 1 that are detachably connected by pins 3, and the guardrail segment 1 includes no less than three support frames made of square tube columns 11 and transverse partitions 12, and the transverse partitions 12 are connected on both sides with corrugated beams 13, and the two sides of the bottom of the square tube 11 are connected with reinforcing beams 14 made of rectangular steel. The corrugated beams 13 are equal in length to the reinforcing beams 14, and no less than three sets of universal wheels 2 are provided at the bottom of the reinforcing beams 14, the support frame at one end of the guardrail segment 1 is provided with a fixed ear piece 15 that does not exceed the corrugated beam 13, and the support frame at the other end of the guardrail segment 1 is provided with a rotatable rotating ear piece 16, and a pullable round tube column 17 is provided in the square tube column 11.

[0024] exist Figure 5 In the figure, the square tube column 11 is represented by a dotted line, see Figure 4 and Figure 5 As shown, in order to solve the problem of low disassembly efficiency caused by the need for the circular tube column inserted into the road surface to be taken out of the guardrail structure as a whole and moved to the outside for storage when the guardrail is moved in the prior art mentioned in the background technology, in the utility model, a pull rod 171 is added to the circular tube column 17, and the length of the pull rod 171 is less than the diagonal length of the inner cross-section of the square tube column 11, and is greater than the side length of the square tube column 11. In this way, when the circular tube column 17 needs to be inserted into the road surface through the square tube column 11, it is only necessary to rotate the circular tube column 17 so that the pull rod 171 is located at the diagonal position of the inner cross-section of the square tube column 11, so that the circular tube column 17 can be easily lowered from the square tube column 11. When the movable guardrail 100 needs to be moved, the pull rod 171 is simply pulled to remove the circular tube column 17 from the ground, and then the circular tube column 17 is rotated to allow the pull rod 171 to overlap the top surface of the square tube column 11, while keeping the bottom surface of the circular tube column 17 out of contact with the ground. Figure 4 As shown, in order to ensure the stability of the round tube column 17 during the movement of the guardrail section 1, the top surface of the square tube column 11 can be provided with a limiting groove 111 corresponding to the pull rod 171.

[0025] See also Figure 5 As shown, the pull rod 171 can be a whole metal rod that is welded and passes through the circular tube column 17, which simplifies the manufacturing process. Figure 6 for Figure 5 Schematic diagram of the assembly relationship structure principle of the square tube column and the round tube column of an improved embodiment based on the present invention; see Figure 6As shown, the pull rod 171 can also be composed of a limiting part 1711 screwed or welded on the symmetrical position of the round pipe column 17 respectively, and a pulling part 1712 fixedly connected with the inner wall of the round pipe column 17, so that the pulling part 1712 is closer to the top surface of the round pipe column 17, thereby facilitating the pulling operation and making the bottom surface of the round pipe column 17 farther from the ground.

[0026] As shown in Figure 1b and Figure 4 As shown in Figure 1b and Figure 4 In the horizontal position, the rotating ear 16 is connected with the support frame through a hinged connection, that is, in the natural state, the rotating ear 16 will fall to the vertical state, that is, it will not extend beyond the wave-shaped beam 13. In the embodiment, two rotating ears 16 are provided, and the two rotating ears 16 need to be operated by hand respectively. In a preferred embodiment, a rotatable connecting rod (not shown in the figure) can be provided between the two rotating ears 16, so that only the uppermost rotating ear 16 needs to be operated by hand.

[0027] As shown in Figure 2 and Figure 3 As shown in

[0028] When the first and second guardrail segments 1 need to be disassembled, first, the second guardrail segment 1 is lifted and placed on the square tube upright 11 so that the bottom surface of the round tube upright 17 is away from the ground, then the pin 3 is pulled out, the second guardrail segment 1 is moved, and when the fixed lug 15 of the second guardrail segment 1 is disconnected from the rotating lug 16 of the first guardrail segment 1, the rotating lug 16 of the first guardrail segment 1 falls to the vertical state under the action of its own gravity. The disassembly of the second guardrail segment 1 is completed, and the disassembly of the entire open movable guardrail 100 provided by the utility model can be completed in the same way.

[0029] In Figures 1a to 4 In the embodiment shown, the wave-shaped beam 13 is a three-wave plate, and those skilled in the art should understand that the wave-shaped beam 13 can also be a two-wave plate.

[0030] The universal wheel 2 is connected to the bottom of the reinforcing beam 14, and each group of the universal wheel 2 includes two wheels arranged on both sides of the reinforcing beam 14, which can more evenly receive the pressure transmitted through the reinforcing beam 14. Figure 1b In addition, the universal wheel 2 should be arranged as close to the square tube upright 11 as possible, so that the overall structure is more balanced.

[0031] The open movable guardrail provided by the utility model has the advantages of simple and stable structure, modular structure, convenient installation and disassembly, and faster realization of the space that needs to be opened.

[0032] Those skilled in the art should understand that although the utility model is described in the form of multiple embodiments, not every embodiment contains only one independent technical solution. The description in the specification is only for the sake of clarity, those skilled in the art should understand the specification as a whole, and the technical solutions involved in each embodiment should be understood as a way of combining different embodiments to understand the protection scope of the utility model.

[0033] The above description is only a specific embodiment of the utility model, and is not used to limit the scope of the utility model. Any equivalent changes, modifications and combinations made by those skilled in the art without departing from the concept and principles of the utility model should be within the scope of protection of the utility model.
