DETAILED DESCRIPTION

[0023] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The utility model provides a technical solution: Figure 1 - Figure 7 The utility model discloses an assembled corrugated guardrail plate, comprising a guardrail plate 1 and a support leg 2. The guardrail plate 1 is composed of two parts: a support plate 12 and a plurality of combination plates 11. The plurality of combination plates 11 are fixed to one side of the support plate 12 by bolts, and the adjacent two combination plates 11 are connected.

[0025] The other side of the support plate 12 is fixedly connected to the support leg 2 via a connecting mechanism 4 , and two adjacent combination plates 11 are connected via a limiting mechanism 3 .

[0026] In this embodiment, when the improved assembled corrugated guardrail panel 1 is used, the support legs 2 are first fixedly installed at corresponding positions on both sides of the road by expansion wires, and then the operator manually moves the support plate 12, and the connecting mechanism 4 performs a fixed connection between the plurality of support legs 2 and the support plate 12, and then the combined plates 11 are fixed to the support plate 12 in sequence by bolts, and the plurality of combined plates 11 are connected into a whole by the limiting mechanism 3, and finally the guardrail panel 1 and the plurality of support plates 12 are assembled into a complete corrugated guardrail panel 1. The corrugated guardrail panel 1 can be assembled by a single person, and the assembly operation is simple;

[0027] When the guardrail plate 1 is damaged due to a collision, the operator only needs to remove the damaged composite plate 11 and replace it with a new composite plate 11 to repair the guardrail plate 1, so that the corrugated guardrail plate 1 can be used normally;

[0028] It should be noted that the above-mentioned support plate 12 is an elastic metal plate.

[0029] In a further preferred embodiment of the present invention, Figure 1 and Figure 4As shown, the limiting mechanism 3 includes a plurality of limiting rods 31, which are divided into two groups and fixedly mounted on the rear side of the combination plate 11. The spacing between two adjacent limiting rods 31 in each group is equal. A circular groove 32 is opened at the position corresponding to the limiting rod 31 on the front side of the combination plate 11. The rear end of the limiting rod 31 located between the two corresponding combination plates 11 is inserted into the corresponding circular groove 32.

[0030] In this embodiment, during the assembly process between the combination panel 11 and the support panel 12, when the operator is splicing two adjacent combination panels 11, the operator can push the limit rod 31 into the circular groove 32 by sliding the combination panel 11 on the support panel 12. After the corrugated guardrail panel 1 is assembled, due to the mutual interference between the limit rod 31 and the inner wall of the circular groove 32, several combination panels 11 are connected into a whole to enhance the strength of the guardrail panel 1 after assembly.

[0031] In a further preferred embodiment of the present invention, Figure 4 As shown, the end of the limiting rod 31 away from the corresponding combination plate 11 is hemispherical, and the portion of the limiting rod 31 located in the corresponding circular groove 32 is connected to the inner wall of the corresponding circular groove 32;

[0032] In this embodiment, the end of the limiting rod 31 is hemispherical in shape to reduce the area of ​​the end of the limiting rod 31, so that the end area of ​​the limiting rod 31 is much smaller than the area of ​​the opening of the circular groove 32, making it easier for the limiting rod 31 to be inserted into the circular groove 32.

[0033] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, the connecting mechanism 4 includes a connecting block 41, which is fixedly mounted on the outer peripheral side of the top of the support leg 2, and the connecting block 41 is fixedly connected to the other side of the support plate 12 by bolts;

[0034] In this embodiment, the provision of the connecting block 41 enables the connecting portion between the supporting leg 2 and the supporting plate 12 to fit tightly with the supporting plate 12 , thereby making the connection between the supporting plate 12 and the supporting leg 2 more stable.

[0035] In a further preferred embodiment of the present invention, Figure 5 - Figure 7 As shown, a plurality of round rods 42 are fixedly mounted on the other side of the support plate 12, and the spacing between two adjacent round rods 42 is equal. The outer ring edge of the right end of the round rod 42 is set in an arc shape. A round hole 43 is opened at the position corresponding to the round rod 42 on the connecting block 41. The right end of the round rod 42 between the support plate 12 and the connecting block 41 is inserted into the round hole 43.

[0036] In this embodiment, when the support plate 12 is connected to the support leg 2, the operator manually moves the support plate 12 and inserts the corresponding round rod 42 on the support plate 12 into the round hole 43 on the connecting block 41. After the operator inserts a round rod 42 into the round hole 43, the operator rotates the support plate 12 with the round rod 42 as the axis, so that the support plate 12 returns to a straight state, and cooperates with the bending deformation of the support plate 12 so that the remaining round rods 42 on the support plate 12 are aligned with the round holes 43 at the position of the other support leg 2. At this time, due to the deformation restoration of the support plate 12, the end of the round rod 42 is stably pressed into the round hole 43, and then the operator can insert the round rod 42 completely into the round hole 43 in turn. The assembly operation between the support plate 12 and the support leg 2 is simple and can be completed by one person, which facilitates the assembly of the device.

[0037] In a further preferred embodiment of the present invention, Figure 5 and Figure 6 As shown, an annular groove 44 having a quarter-circular cross-section is formed on the outer peripheral wall of the round rod 42, and an annular storage groove 45 is formed on the inner wall of the circular hole 43 at a position corresponding to the annular groove 44. An elastic ring 46 having a semi-annular cross-section is disposed in the storage groove 45, and the outer ring wall of the elastic ring 46 is fixedly connected to the inner wall of the storage groove 45. The portion of the elastic ring 46 close to the annular groove 44 is inserted into the annular groove 44 and contacts the inner wall of the annular groove 44.

[0038] In this embodiment, during the process of inserting the round rod 42 into the circular hole 43, when the arc surface of the round rod 42 moves to the position of the inner arc wall of the elastic ring 46, due to the mutual interference between the arc surface of the round rod 42 and the inner arc wall of the elastic ring 46, the elastic ring 46 can be pressed into the annular groove 44 along the inner arc wall of the elastic ring 46, so that the round rod 42 can be completely inserted into the circular hole 43. When the support plate 12 and the connecting block 41 interfere with each other, the elastic ring 46 aligns with the annular groove 44, and the elastic ring 46 resets its deformation and automatically inserts into the annular groove 44. At this time, due to the mutual interference between the elastic ring 46 and the inner wall of the annular groove 44, a restraining force can be applied to the round rod 42 and the connecting block 41, and the round rod 42 is inserted into the circular hole 43 more stably, preventing the round rod 42 from directly slipping out of the circular hole 43 when the support plate 12 is rotated. This affects the assembly operation of the device.

[0039] Working Principle: When using this improved assembled corrugated guardrail, the operator first fixes the support legs 2 to the corresponding positions on both sides of the road using expansion wires. Then the operator manually moves the support plate 12 and inserts the corresponding round rod 42 on the support plate 12 into the round hole 43 on the connecting block 41;

[0040] In the process of inserting the round rod 42 into the circular hole 43, when the arc surface of the round rod 42 moves to the position of the inner arc wall of the elastic ring 46, due to the mutual interference between the arc surface of the round rod 42 and the inner arc wall of the elastic ring 46, the elastic ring 46 can be pressed into the annular groove 44 along the inner arc wall of the elastic ring 46, so that the round rod 42 can be completely inserted into the circular hole 43. When the support plate 12 and the connecting block 41 interfere with each other, the elastic ring 46 aligns with the annular groove 44, and the elastic ring 46 resets its deformation and automatically inserts into the annular groove 44. At this time, due to the mutual interference between the elastic ring 46 and the inner wall of the annular groove 44, a restraining force can be applied to the round rod 42 and the connecting block 41, so that the round rod 42 is more stably inserted into the circular hole 43.

[0041] After the operator inserts a round rod 42 into the round hole 43, the operator rotates the support plate 12 with the round rod 42 as the axis, so that the support plate 12 returns to a straight state. At this time, the remaining round rods 42 on the support plate 12 are aligned with the round holes 43 at the positions of the other support legs 2. At this time, the operator presses the corresponding round rod 42 into the round hole 43 of the connecting block 41 on the support leg 2. At this time, due to the mutual interference between the multiple elastic rings 46 and the inner wall of the annular groove 44, the support plate 12 is constrained and limited on the multiple support legs 2. Then the operator screws the bolts into the connecting block 41 and the support plate 12 to lock the position between the connecting block 41 and the support plate 12;

[0042] After the assembly between the support plate 12 and the support leg 2 is completed, the operator sequentially fits the combined plate 11 on the support plate 12 and uses bolts to fix the combined plate 11 and the support plate 12 to complete the assembly of the corrugated guardrail plate;

[0043] During the assembly process between the combined panels 11 and the support panels 12, when the operator is splicing two adjacent combined panels 11, the operator can push the limiting rod 31 into the circular groove 32 by sliding the combined panels 11 on the support panels 12. After the corrugated guardrail panel is assembled, the limiting rod 31 and the inner wall of the circular groove 32 interfere with each other, so that the combined panels 11 are connected into a whole, thereby enhancing the strength of the assembled guardrail panel 1.

[0044] When the guardrail panel 1 is damaged due to a collision, the operator only needs to perform the reverse operation according to the above-mentioned installation part to remove the damaged combination plate 11 to repair the guardrail panel 1, so that the corrugated guardrail panel 1 can be used normally.

[0045] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
