[0026] Please refer to Figure 1-6 As shown, a guardrail for construction engineering includes a bottom plate 1, a top plate 101 is arranged just above the bottom plate 1, sleeves 102 are fixedly connected to both sides of the top of the bottom plate 1, the inside of the sleeve 102 is connected to the top plate 101 through an adjustment mechanism 2, and a plurality of groups of telescopic rods 103 are evenly arranged between the two groups of sleeves 102. The telescopic rods 103 and the sleeves 102 have the same height, and the bottom of the telescopic rods 103 is fixedly installed on the top of the bottom plate 1, and the telescopic end of the telescopic rod 103 is fixed to the bottom end of the top plate 101. A first T-block 104 is installed on one side of the top of the top plate 101, a first T-slot 105 matched with the first T-block 104 is opened on the other side of the top of the top plate 101, and a second T-block 106 is fixedly connected to one side of the back of the bottom plate 1, a fixing plate 107 is installed on the other side of the back of the bottom plate 1, a second T-slot 108 is opened on the top of the fixing plate 107, the second T-slot 108 is matched with the second T-block 106, and a fixing mechanism 3 is also installed on the top of the fixing plate 107.

[0027] In the present solution, the height of the guardrail can be adjusted by the adjusting mechanism 2, so that the guardrail can be well adapted to different construction sites. When two groups of guardrails are connected, after the heights of the two groups of guardrails are adjusted to be consistent, the first T-block 104 on the top plate 101 of one group of guardrails is stuck in the first T-slot 105 on the top plate 101 of the other group of guardrails. At this time, the second T-block 106 is also stuck in the second T-slot 108. Finally, it can be fixed by the fixing mechanism 3, which is convenient and quick and meets the needs of the staff.

[0028] Example 2

[0029] Please refer to Figure 5 As shown, the adjustment mechanism 2 includes a screw rod 201 and a lifting block 202. The screw rod 201 is rotatably connected to the inside of the sleeve 102, and the lifting block 202 is threadedly connected to the outer surface of the screw rod 201. Two sets of connecting rods 203 are fixedly connected to the top of the lifting block 202. The other end of the connecting rod 203 extends to the outside of the sleeve 102 and is fixedly connected to the top plate 101.

[0030] Please refer to Figure 5 As shown, the bottoms of the screw rods 201 on both sides extend to the inside of the bottom plate 1 and are fixedly mounted with rotating wheels 204 . The two sets of rotating wheels 204 are connected by a belt 205 , and a hand wheel 206 is fixedly connected to the bottom end of one set of rotating wheels 204 .

[0031] Please refer to Figure 1 and Figure 2 As shown, a bolt 109 is fixedly connected to the front side of the base plate 1 , and a cover plate 110 is threadedly connected to the outer surface of the bolt 109 . The position of the cover plate 110 corresponds to the position of the hand wheel 206 .

[0032] In this solution, the working principle of the adjustment mechanism 2 is as follows: when the height of the guardrail needs to be adjusted, the cover plate 110 is rotated to expose the opening on the front side of the base plate 1, and the hand is inserted into the interior of the base plate 1 and the hand wheel 206 is rotated to rotate one set of the rotating wheels 204. Driven by the belt 205, the rotating wheels 204 and the screw rod 201 on both sides rotate synchronously as a whole, and then the lifting block 202 moves up and down, causing the connecting rod 203 to move up and down, driving the top plate 101 to move up and down, thereby changing the overall height of the guardrail.

[0033] Example 3

[0034] Please refer to Figure 4 and Figure 6As shown, the fixing mechanism 3 includes a first connecting plate 301 and a second connecting plate 308, and the first connecting plate 301 and the second connecting plate 308 are respectively rotatably connected to the top two sides of the fixing plate 107, and a mounting groove 302 is provided on the first connecting plate 301, and the interior of the mounting groove 302 is connected to the movable block 304 through a spring 303, and a clamping block 305 is fixedly connected to the other side of the movable block 304, and a clamping groove 309 adapted to the clamping block 305 is provided at one end of the second connecting plate 308.

[0035] Please refer to Figure 6 As shown, a limiting groove 306 is provided on the first connecting plate 301 , a limiting block 307 adapted to the limiting groove 306 is fixedly connected to the inner side of the movable block 304 , and the limiting block 307 is slidably connected to the inside of the limiting groove 306 .

[0036] In this solution, the working principle of the fixing mechanism 3 is as follows: after the first T-block 104 is stuck in the first T-slot 105 and the second T-block 106 is stuck in the second T-slot 108, the first connecting plate 301 is rotated to make the first connecting plate 301 in a horizontal state, and the movable block 304 is pulled to make the spring 303 in a contracted state, and then the second connecting plate 308 is also rotated to make the end of the second connecting plate 308 with the slot 309 located inside the first connecting plate 301, and then the movable block 304 is released, and under the action of the spring 303 restoring the deformation, the movable block 304 is quickly reset, driving the block 305 to be stuck in the slot 309, connecting the first connecting plate 301 and the second connecting plate 308 together, and covering the top of the second T-slot 108, thereby realizing the convenient and quick fixing of the two sets of guardrails together.
