A construction fence for easy installation according to some embodiments of the present utility model will be described with reference to fig. 1 to 6.

As shown in fig. 1 to 6, the construction guardrail convenient to install comprises a guardrail main body consisting of two support columns 1 and two cross rods 2, wherein the cross rods 2 are distributed between the two support columns 1 from top to bottom, and the cross rods 2 can connect the two support columns 1, so that the support columns 1 and the cross rods 2 are combined into a whole. The bottom ends of the support columns 1 are distributed with support legs 4 for supporting the support columns, and the combined guardrail main body can be stably placed through the support legs 4.

Preferably, guide grooves 5 are formed in positions, corresponding to the cross bars 2, on the support columns 1, the guide grooves 5 with the same height are symmetrically arranged, and clamping blocks 501 are arranged in the guide grooves 5. The two ends of each cross rod 2 are provided with the connecting components 3, the connecting components 3 can slide into the guide grooves 5 and are fast clamped with the clamping blocks 501, and meanwhile, the connecting components 3 can also be separated from the clamping blocks 501 to complete the disassembly from the support columns 1. The setting of coupling assembling 3 can be convenient for the installation of horizontal pole 2 and support column 1, still saves the manual work simultaneously and screw up a plurality of screws repeatedly and extravagant time, has improved work efficiency.

As shown in fig. 4, the connection assembly 3 includes a connection board 301 disposed at an end of the cross bar 2, two ends of the connection board 301 are rotatably provided with a rotation board 302 through a connection shaft, two opposite sides of the two rotation boards 302 are respectively provided with a limiting block 304, the limiting blocks 304 are specifically inclined blocks, and front ends of the limiting blocks 304 are inclined planes, and the limiting blocks 304 can be clamped with the clamping blocks 501. Each connecting shaft is sleeved with a rotating spring 303, one end of each rotating spring 303 is connected with the connecting plate 301, and the other end is connected with the rotating plate 302 correspondingly arranged.

Specifically, the tail of the rotating plate 302 is provided with a U-shaped groove, and the corresponding rotating springs 303 drive the connecting plate 301 to rotate around the inner side of the connecting plate 301 in the connecting axial direction. When the top surface of the U-shaped groove is attached to the front end surface of the connecting plate 301, the rotating plate 302 stops rotating, so that the limiting effect of the connecting plate 301 on the rotating plate 302 is achieved. In order to facilitate the outward rotation of the rotation plates 302 on the connection plates 301, as shown in fig. 5, corners of the connection plates 301 near the rotation plates 302 are rounded.

When the connecting component 3 arranged on the cross rod 2 is connected with the support column 1, the connecting component 3 is pushed to be installed at the position where the guide groove 5 is formed in the support column 1, the limiting block 304 on the connecting component 3 is aligned with the guide groove 5 and slides into the guide groove 5, when the inclined surface of the limiting block 304 on the connecting component 3 is contacted with the clamping block 501 in the guide groove 5, each rotating plate 302 is outwards opened along with the limiting block 304 arranged on the rotating plate, and then when the connecting plate 301 is pushed to be attached to the side wall of the support column 1, each limiting block 304 is correspondingly provided with the clamping block 501 in a clamping manner, so that the installation of the cross rod 2 and the support column 1 provided with the connecting component 3 is completed. When the connecting component 3 is detached from the supporting column 1, the rotating plate 302 can be rotated outwards, the limiting block 304 is separated from the clamping block 501, and then the connecting component 3 is detached through the cross rod 2. The connecting assembly 3 and the support column 1 are convenient and quick to assemble and disassemble, and the purposes of improving the working efficiency of workers are achieved in a time-saving and labor-saving manner. As shown in fig. 2, the inner top corners of the guide grooves 5 are chamfered, so that the stoppers 304 are more smoothly inserted into the guide grooves 5. Simultaneously, guide slot 5 also plays the spacing effect to coupling assembling 3 in vertical direction, prevents coupling assembling 3 downwardly sliding under the action of gravity.

It should be noted that, as shown in fig. 1, the cross bar 2 includes a first cross bar 201 and a second cross bar 202, and the second cross bar 202 is slidably disposed in the first cross bar 201, and a connecting assembly 3 is disposed at a far end of the first cross bar 201 and the second cross bar 202. When the construction guardrail convenient to install is used, the second cross rod 202 can be pulled out or pushed in from the first cross rod 201 according to the field use area to adjust the occupied area of the construction guardrail convenient to install.

As another preferred, a rotating rod 8 is rotatably provided in each support column 1, a hand wheel 9 is provided at the top end of the rotating rod 8, and a worm 801 is provided at the bottom end of the rotating rod 8. The bottom of each support column 1 is distributed with a setting groove 101, a rotating shaft 601 is arranged in each setting groove 101 in a rotating mode, and supporting legs 4 are fixedly arranged on each rotating shaft 601. Grooves 6 are formed in the supporting legs 4, the rotating shaft 601 penetrates through the grooves 6, worm gears 7 are fixedly arranged on the rotating shafts located in the grooves 6, and the worm 801 is meshed with the corresponding worm gears 7. The worm 801 rotates to drive each worm wheel 7 connected with the worm 801 to rotate around the rotating shaft 601, and simultaneously, the support legs 4 correspondingly connected to the worm wheels 7 through the rotating shaft 601 also synchronously rotate.

The setting of the setting groove 101 can accomodate landing leg 4 to reduce the area occupied by landing leg 4, also be convenient for simultaneously to the transport of support column 1. When the convenient construction guardrail is used, the hand wheel 9 can be rotated to rotate out each supporting leg 4 stored in the placement groove 101 by taking the corresponding rotating shaft 601 as the center. Specifically, the hand wheel 9 drives the bull stick 8 and worm 801 that bottom is connected rotate, worm 801 drives worm wheel 7 rather than being connected correspondingly, and worm wheel 7's rotation can drive landing leg 4 that connects respectively and revolute the axis of rotation 601 and rotate as the center, and the rotation angle accessible hand wheel 9 of each landing leg 4 rotates the distance and control, so not only can accomodate landing leg 4 when the construction guardrail of convenient installation is not used and reduce landing leg 4 area, can also control the expansion angle of landing leg 4 according to the in-service use condition when using the construction guardrail of convenient installation to use to different construction areas, thereby improve the construction guardrail practicality of convenient installation.

The using method comprises the following steps: the cross rod 2 provided with the connecting component 3 is installed at the position, corresponding to the support column 1, provided with the guide groove 5, during installation, firstly the limiting block 304 of the connecting component 3 is inserted into the guide groove 5, then the connecting component 3 is continuously pushed to clamp the limiting block 304 with the clamping block 501, connection of the cross rod 2 through the connecting component 3 and the support column 1 is completed, and then the supporting leg 4 is unfolded through rotating the hand wheel 9, so that the construction guardrail convenient to install is placed.
