[0002] During construction, the construction site environment is complex. In order to prevent pedestrians and unauthorized personnel from entering by mistake and reduce accidents caused by chaos, it is necessary to use guardrails to isolate and maintain order on the construction site. This solution specifically involves a construction site guardrail structure.

[0003] When using the existing construction site guardrail structure, due to the large scope of the construction site, multiple guardrails need to be connected and installed for protection. The guardrails take up a large space, are inconvenient to fold and unfold for use, and are inconvenient to store and transport. When the construction area is changed, the guardrails need to be moved to the designated location, which is inconvenient to move and fix the entire structure. Utility Model Content

[0011] As a further solution of the present invention, the screw rod passes through the interior of the column and is arranged in a threaded connection, and the hook is located in the interior of the hanging tube and is arranged in a clamping connection.

[0012] As a further solution of the present invention, the bottom end of the screw is connected to the lifting frame via a bearing, and the lifting frame is located between the two lifting slots and is slidable up and down.

[0013] The beneficial effects of the utility model are as follows:

[0014] By setting up a folding assembly, the two fences are rotated by the connection of the hinge shaft, which facilitates the folding and unfolding of the fence, facilitates the overall storage and transportation, and reduces the occupied space. Through the threaded connection of the stud and the screw hole, the guide rod is located in the fixed block and rotates and slides, which facilitates the rapid fixation of the two fences after unfolding and improves the overall stability.

[0015] By setting up a moving component, the fence is hung and fixed with a hook and a hanging tube. The screw is lifted and lowered inside the column under the action of the thread, so that the lifting frame can rise and fall synchronously. The contact and separation of the roller with the ground can facilitate the movement and fixation of the fence as a whole, and reduce the handling operations of personnel.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a construction site guardrail structure includes two columns 1, a folding component 2 is installed between the two columns 1, the folding component 2 includes two fence bodies 4, a hinge shaft 5 is connected and installed between the two fence bodies 4, two hanging tubes 6 are fixedly installed on the outer sides of the two fence bodies 4, two fixing blocks 7 are fixedly installed on the inner sides of the rear parts of the two fence bodies 4, a guide rod 8 is movably installed inside the two fixing blocks 7 passing through the rear of one of the fence bodies 4, a knob 9 is fixedly installed on the outer end of the guide rod 8, a stud 10 is fixedly installed on the inner end of the guide rod 8, and screw holes 11 are provided on the inner sides of the two fixing blocks 7 at the rear of the other fence body 4.

[0024] In this embodiment, the two fence bodies 4 are movably connected via a hinge shaft 5 , and the two fence bodies 4 are symmetrically arranged.

[0025] The two fence bodies 4 can rotate relative to each other through the connection of the hinge shaft 5, which facilitates the folding and unfolding of the two fence bodies 4 and facilitates the storage of the entire structure.

[0026] In this embodiment, the fixing blocks 7 at the rear of the two fence bodies 4 correspond to each other, and the guide rod 8 passes through the interior of the fixing block 7 and is movably rotatable.

[0027] When the two fence bodies 4 are unfolded and parallel to each other, they are connected by rotating the knob 9, and the guide rod 8 is located inside the fixed block 7 and slides to extend and retract.

[0028] In this embodiment, the diameter of the stud 10 is greater than the diameter of the guide rod 8 , and the stud 10 and the screw hole 11 are threadedly connected.

[0029] The stud 10 is connected in the screw hole 11 by a thread, so that the two fence bodies 4 are fixed after being unfolded to prevent shaking and bending.

[0030] In this embodiment, a moving component 3 is installed inside the column 1. The moving component 3 includes a screw 12. The screw 12 is installed through the interior of the column 1. A turntable 13 is fixedly installed on the top of the screw 12. Two hooks 14 are fixedly installed on both sides of the column 1. Lifting grooves 15 are provided on the inner walls on both sides of the bottom end of the column 1. A lifting frame 16 is movably installed at the bottom end of the screw 12 and located between the two lifting grooves 15. Rollers 17 are installed on both ends of the bottom of the lifting frame 16.

[0031] By rotating the turntable 13, the screw rod 12 drives the lifting frame 16 to move up and down under the action of the thread, thereby making the roller 17 contact or disengage with the ground, thereby performing overall movement and fixation.

[0032] In this embodiment, the screw rod 12 passes through the interior of the column 1 and is threadedly connected, and the hook 14 is located inside the hanging tube 6 and is clamped.

[0033] Under the action of the screw thread of the screw 12 , the screw 12 is moved up and down inside the column 1 , and the lifting frame 16 is positioned between the two lifting slots 15 to guide and lift the screw 12 , so as to facilitate the height adjustment of the roller 17 .

[0034] In this embodiment, the bottom end of the screw rod 12 is connected to the lifting frame 16 via a bearing. The lifting frame 16 is located between the two lifting slots 15 and is slidable up and down.

[0035] When the screw 12 rotates and drives the lifting frame 16 to rise and fall, the lifting frame 16 is prevented from rotating with the screw 12 through the connection of the bearing, and the roller 17 follows the rise and fall and contacts or separates from the ground, which facilitates the overall movement and fixation.

[0036] It should be noted that the present invention is a construction site guardrail structure. When in use, the two columns 1 are fixed at the designated position at the construction site. When installing the fence body 4, the two fence bodies 4 are unfolded through the connection of the hinge shaft 5, and the two knobs 9 are rotated respectively to connect the studs 10 with the screw holes 11, thereby fixing the two fence bodies 4 to each other. The hanging tubes 6 on the outside of the two fence bodies 4 are then hung on the hooks 14 of the corresponding columns 1, and protection is provided by the fence body 4. When moving the position, the two turntables 13 are rotated respectively to rotate the screw rod 12 and move downward under the action of the thread. The lifting frame 16 is connected to the screw rod 12 through the bearing and is located between the two lifting slots 15 and follows the synchronous decline, so that the two rollers 17 are in contact with the ground, and the overall movement is performed by the rotation of the rollers 17.

[0037] 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 are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention 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 in this invention is defined by the appended claims and their equivalents.
