Compared with the prior art, the fence has the advantages that firstly, when the fence encloses a maintenance position, the clamping rods are pulled out according to the corresponding positions of the handrails, the circular plates and the bearing plates fixed by the clamping rods can move, and the first transverse rods rotate at the positions of the rotating shafts at the top ends of the handrails; meanwhile, a connecting rod is pulled by a rotating first cross rod to move at the position of a sliding groove under the action of a sliding block, at the moment, rotation of the connecting rod enables the position of a circular plate to correspond to the angle of a rotating shaft driven by the first cross rod, and therefore the angle of the handrail is rotated to correspond to the maintenance position; therefore, the range enclosed by the fence can be adjusted according to maintenance positions of different shapes, and the fence is prevented from occupying too many positions to affect normal walking.

Description

Technical Field

[0001] The utility model relates to a safety warning fence, belonging to the field of warning fences. Background Art

[0002] Highway refers to the public roads between cities, between urban and rural areas, and between villages that have been accepted and approved by the transportation authorities and can be used for driving. It includes highways that have already been built and approved by the transportation authorities. The construction of highways has greatly facilitated people's travel. In the actual use of highways, they are easily damaged due to wind, sun, rain or long-term use and wear. In order to ensure people's safe and smooth travel, highways need to be maintained and repaired in a timely manner when they are damaged.

[0003] In the prior art, when maintaining and repairing a highway, a safety warning fence needs to be used. The safety warning fence is composed of a railing, a warning sign, a cross bar, a bottom plate and a cross bar. Therefore, when using the safety warning fence, the safety warning fence needs to be arranged around the maintenance position. At this time, the railing and the cross bar are assembled, and the baffle separates the distance between the two railings, and then the warning sign is placed on the surface of the safety warning fence, so that the safety warning fence separates the maintenance position. However, when the safety warning fence is used, since the direction of a group of fences is fixed, and the size of the maintenance position required each time is different, the isolation range of the fence is also different. When the top corner of the maintenance position is surrounded by one of the railings of the fence, the placement position of the group of fences needs to correspond to the maintenance position, so that the position surrounded by the fence is larger than the maintenance position, and it is necessary to use one more fence to correspond to it in order to completely enclose the maintenance position.

[0007] Furthermore, a receiving rod is arranged at each top corner of the bottom of the baffle, the bottom of each receiving rod is connected to a bottom block, the bottom of the bottom block contacts the top surface of the circular plate, and the number and position of the connecting rods correspond to the receiving rods.

[0008] Furthermore, a rotating shaft is arranged at the contact position between the first cross bar and the two railings, and both ends of the rotating shaft contact the circular plate and the receiving plate. The center of the clamping ring is open, the clamping ring is fixed on the surface of the railing, and the clamping rod passes through the circular plate and the receiving plate at the same time.

[0009] Furthermore, a slot is provided inside the second cross bar, a fixing block is fixedly connected to the side end of the second cross bar, a rotating rod is rotatably connected to the bottom of the fixing block, an arc plate is fixedly connected to the surface of the rotating rod, and a bolt is threadedly connected to the surface of the arc plate.

[0010] Furthermore, both ends of the rotating rod are in contact with a fixed block respectively, a second cross bar is arranged between the two railings, and four fixed blocks with mutually symmetrical positions are arranged on both sides of the second cross bar.

[0011] Furthermore, the bolt passes through the arc plate and contacts the surface of the railing, and the width of the slot matches the width of the arc plate.

[0012] The beneficial effects of the utility model are as follows: first, when the fence is used to enclose a maintenance position, the clamping rod is pulled out according to the corresponding position of the railing, and the circular plate and the receiving plate fixed by the clamping rod can move, and the position of the first cross bar is rotated at the position of the rotating shaft at the top of the railing, and at the same time, the connecting rod is pulled by the rotating first cross bar and moves in the position of the slide groove under the action of the slider. At this time, the rotation of the connecting rod makes the position of the circular plate correspond to the angle driven by the rotating shaft by the first cross bar, so that the angle of the railing is rotated to correspond to the maintenance position, so that the range of the fence can be adjusted according to the maintenance positions of different shapes, thereby preventing the fence from occupying too much position and affecting normal walking;

[0013] Secondly, it is necessary to rotate the arc plate at the position of the rotating rod, so that the arc plate can be separated from the range of the second cross bar from the inside of the slot, and at the same time, the arc plate can be matched with the railing at the position where the railing needs to be raised, so that the two arc plates are attached to the surface of the railing, and at the same time, the bolts pass through the arc plate and contact the surface of the railing, so that the assembly of the second cross bar and the railing can be more convenient, and the position of the second cross bar on the surface of the railing can be adjusted to achieve the shielding of different positions.
