[0020] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] like Figures 1-2 As shown, a sign for easy installation and disassembly during highway maintenance work includes a sign body 1, and also includes:

[0023] The signpost 2 and the sign body 1 are detachably installed on the top of the signpost 2; the back of the sign body 1 is provided with several stiffening rods 11, and the stiffening rods 11 are provided with signpost caps 12. The signpost caps 12 are fitted on the top of the signpost 2 and are fixed to the signpost 2 by means of pins 13.

[0024] Specifically, during installation, the sign and sign post cap 12 should be inserted into the sign post 2 as a whole, and then the sign post cap 12 should be fixed to the sign post 2 with pins 13. When replacing the sign, the pins 13 can be pulled out, and then the sign and sign post cap 12 can be removed as a whole, which can achieve quick installation and replacement.

[0025] The signpost 3 and the signpost column 2 pass through the signpost 3 and are fixedly connected to the signpost 3; several stiffening plates 21 are welded at the angle between the side wall of the signpost column 2 and the top of the signpost 3 to increase the connection strength between the signpost column 2 and the signpost 3.

[0026] The height adjustment frame 4 includes a movable part 41, a fixed part 42, and an adjustment part 43. The movable part 41 and the fixed part 42 are connected through the adjustment part 43. The sign cross brace 3 is installed on the movable part 41, and the height of the adjustment frame 4 is adjusted by adjusting the adjustment part 43.

[0027] The activity section 41 includes a first horizontal square steel 411, a first steel sleeve 412 fixed to the top of the first horizontal square steel 411, and a second steel sleeve 413 fixed to the bottom of the first horizontal square steel 411. A first sealing plate 414 is provided on the top of the first steel sleeve 412. The signboard cross brace 3 is fixed to the side of the first horizontal square steel 411 away from the roadside corrugated guardrail 6.

[0028] The fixing part 42 includes a second horizontal square steel 421, a third steel sleeve 422 fixed to the top of the second horizontal square steel 421, and a fourth steel sleeve 423 fixed to the bottom of the second horizontal square steel 421. The bottom of the fourth steel sleeve 423 is provided with a second sealing plate 424.

[0029] The adjusting part 43 includes a screw 431, a connecting rod 432 fixed to the center of the top of the screw 431, and a rotating rod 433 fixed to the top of the connecting rod 432. The screw 431 is placed inside the third steel sleeve 422 and is threadedly connected to the third steel sleeve 422. The screw 431 and the connecting rod 432 pass through the first horizontal square steel 411. The second steel sleeve 413 is slidably sleeved on the outer wall of the third steel sleeve 422. The contact surfaces of the two are coated with anti-rust lubricant to ensure that the two can slide freely up and down. The connecting rod 432 passes through the first sealing plate 414 and is rotatably connected to the first sealing plate 414.

[0030] Specifically, the first horizontal square steel 411 and the second horizontal square steel 421 are connected by a screw 431 and a third steel sleeve 422. The relative movement between the two is achieved by rotating the rotating rod 433, thereby realizing the overall installation and disassembly of the sign.

[0031] The guardrail connector 5 is connected to one side of the movable part 41 and the fixed part 42 respectively. The entire sign is secured to the roadside corrugated guardrail plate 6 by the guardrail connector 5. The guardrail connector 5 includes an angle steel 51 and an angle steel welded backing plate 52. One side of the angle steel welded backing plate 52 is welded and fixed to the side of the first horizontal square steel 411 and the second horizontal square steel 421 near the roadside corrugated guardrail plate 6 respectively. One side of the angle steel 51 is welded and fixed to the angle steel welded backing plate 52. The other side is clamped to the top and bottom of the roadside corrugated guardrail plate 6 and is pressed and clamped by the adjusting part 43.

[0032] Specifically, the dimensions of the side of the angle steel 51 that contacts the roadside corrugated guardrail 6 are closely matched with the shape of the roadside corrugated guardrail 6, the included angle of the angle steel 51 is less than 45 degrees, the side of the angle steel welded backing plate 52 that is close to the angle steel 51 is closely matched with the other side of the angle steel 51, and the sign is fixed to the roadside corrugated guardrail 6 by the angle steel 51, which facilitates installation and disassembly.

[0033] During on-site installation, first adjust the spacing between the first horizontal square steel 411 and the second horizontal square steel 421 according to the specific style of the roadside corrugated guardrail 6, ensuring that the upper and lower angle steel 51 are located outside the roadside corrugated guardrail 6. Adjust the rotating rod 433 in the direction of shortening the spacing between the first horizontal square steel 411 and the second horizontal square steel 421, and then fasten the signboard as a whole to the roadside corrugated guardrail 6.

[0034] Similarly, during disassembly, simply manually adjust the rotating rod 433 to adjust the spacing of the first horizontal square steel 411 so that the angle steel 51 can be easily removed.

[0035] The back panel of the sign is equipped with two stiffening rods 11, and the sign post cap 12 is fixed on the stiffening rods 11. When the sign needs to be replaced temporarily at the construction site, it is only necessary to pull out the pin 13 and then take out the sign as a whole to complete the replacement.

[0036] The installation and dismantling of the signboard of this utility model is quick and convenient, the on-site operation process is short, which is conducive to construction and suitable for maintenance work; the connection between the signboard and the roadside corrugated guardrail 6 is safe and reliable, which improves the stability of the entire signboard; this utility model greatly improves the safety and standardization of the on-site layout of the signboard.
