[0002] Guardrails are fences set up to protect people's safety. They are usually used to enclose dangerous areas to prevent people from entering or leaving the area. Guardrails have the functions of protection, warning and guidance. At the same time, guardrails also have the function of regional division: guardrails can be used to demarcate the boundaries of different areas and realize the rational use and management of space. The guardrails used in the post station can isolate and guide people entering and leaving the post station, and can also divide the equipment and items into areas.

[0003] In order to facilitate carrying, existing guardrails are mostly designed in sections. Before use, workers are required to assemble the guardrails piece by piece.

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] Embodiment 1

[0044] See also Figure 1-5 A post guardrail comprises a guard assembly 1, wherein the guard assembly 1 comprises: side posts 11, between which guardrails 12 are arranged; connecting frames 13, symmetrically arranged on the back sides of two groups of side posts 11, the right side wall of the side posts 11 is provided with the first connecting frame 13, and the left side wall of the side posts 11 is provided with the second connecting frame 13; a connecting assembly 2 is arranged on the connecting frame 13, and the connecting assembly 2 comprises: a connecting block 21, arranged on the right side wall of the first connecting frame 13; a fixing hole 22, which is opened on the connecting block 21 On the top; a cavity 23, arranged on the left side wall of the second connecting frame 13; a frame body 24, arranged inside the cavity 23; a fixed block 25, symmetrically arranged in the frame body 24, and the top and bottom of the frame body 24 are symmetrically provided with through grooves for the movement of the fixed block 25; a spring 251, arranged on the opposite surface of the fixed block 25; a slide bar 26, symmetrically arranged on the right side wall of the fixed block 25, and the right end of the slide bar 26 extends to the right side of the frame body 24; a linkage mechanism 27, arranged on the connecting frame 13 and the frame body 24. The linkage mechanism 27 includes: a spring 271, one end of which is fixedly connected to the right side wall of the frame 24; a pull rod 272, which is fixedly connected to the other end of the spring 271, and the right end of the pull rod 272 penetrates and extends to the outside of the connection frame 13; a connecting rod 273, which is symmetrically hinged to the left end of the pull rod 272; a moving block 274, which is symmetrically and rotationally connected to the connecting rod 273; a dovetail block 275, which is arranged on the left side wall of the moving block 274; and a dovetail groove 276, which is opened on the right side wall of the frame 24, and the dovetail block 275 is slidably connected to the dovetail block 275. The connecting assembly 2 is symmetrically opened with multiple groups.

[0045] When in use, the side column 11 and the guardrail 12 block objects or people. Before use, the staff first uses the connecting component 2 to connect the side columns 11: first pull the pull rod 272 in the linkage mechanism 27, the pull rod 272 extends to the outside of the second connecting frame 13, and stretches the second spring 271. The pull rod 272 simultaneously drives the two hinged connecting rods 273 to move, and the connecting rod 273 pushes the moving blocks 274 to approach each other. The moving block 274 drives the two sliding rods 26 and the fixed block 25 to approach each other. At this time, the connecting block 21 is completely extended into the cavity 23, and the pull rod 272 is released. The elastic force generated by the stretching deformation of the second spring 271 drives the pull rod 272 to retract into the second connecting frame 13, and the linkage slide rod 26 and the fixed block 25 move outward, and the fixed block 25 enters the fixing hole 22. The fixed block 25 restricts the connecting block 21 to complete the connection between the connecting frames 13. The staff stretches the rod 272 in the linkage mechanism 27 to retract the two fixing blocks 25 into the frame 24 at the same time. When the connection block 21 extends into the cavity 23, the rod 272 is released, and the fixing block 25 enters the fixing hole 22, so that the connection and fixation of the connection block 21 can be achieved without carrying additional tools, which is convenient and quick. At the same time, when the connection frame 13 needs to be separated, the rod 272 is pulled to disengage the fixing block 25 from the fixing hole 22, and the connection block 21 can be taken out of the cavity 23. The connection assembly 2 has multiple groups symmetrically, so that multiple groups of fixing blocks 25 can be fixedly connected to the fixing hole 22, thereby improving the stability of the connection frame 13 after connection.

[0046] Embodiment 2

[0047] On the basis of the first embodiment, an auxiliary function is added.

[0048] See also Figure 1-5 The fixing block 25 has an inclined surface on one side close to the connecting block 21. A slider 252 is provided on the outer wall of the fixing block 25, and a slide groove 253 is provided on the inner wall of the frame body 24. The slider 252 is slidably connected to the slide groove 253. A rotating shaft 3 is rotatably connected between the first connecting frame 13 and the connecting block 21, and a screw hole is passed through the rotating shaft 3, and a bolt 31 is threadedly connected in the screw hole.

[0049] The inclined surface on the fixed block 25 allows the staff to achieve the connection between the connection frames 13 without pulling the pull rod 272 in advance: when the connection block 21 extends into the cavity 23, the connection block 21 contacts the inclined surface of the fixed block 25 and squeezes the fixed block 25 into the frame 24, and compresses the spring 1 251 to facilitate the movement of the connection block 21. When the fixing hole 22 on the connection block 21 moves to the same axis as the fixed block 25, the fixed block 25 is elastically ejected into the fixing hole 22 by the elastic force generated by the deformation of the spring 1 251, completing the quick installation of the connection frame 13 and improving the convenience of the staff's operation. When the fixed block 25 is moving, it drives the slider 252 to slide in the slide groove 253. The slider 252 and the slide groove 253 increase the stability of the fixed block 25 when it moves, guide the movement of the fixed block 25, and facilitate the accurate entry of the fixed block 25 into the fixing hole 22. The rotating shaft 3 allows the angle between the connecting frames 13 to be changed by rotation after the two connecting frames 13 are connected, so that the side columns 11 and the guardrails 12 can protect the corners. When the guardrails 12 do not need to protect the corners, the staff can screw the bolts 31 through the screw holes. The bolts 31 limit the rotating shaft 3 to prevent the rotating shaft 3 from rotating, thereby increasing the stability of the connecting frames 13 after connection.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
