Wherein more telescopic support columns and horizontal connecting rods can be added to increase the length of the fence. When the height of the fence is required to be increased, the vertical sliding limiting rod 13 extending into the first round opening 10 and the second round opening 12 is pulled up by pulling the handle 24, so that the vertical sliding limiting rod 13 leaves the limiting groove 17. At this time, the circular stopper 14 pushes the compression spring 15 to deform. Wherein the portal bracing frame 11 plays a role of supporting the vertical sliding limiting rod 13. Then the rocking handle 21 is shaken to enable the gear 20 in the first strip-shaped opening 19 to rotate, the gear 20 and the rack 18 are matched to drive the horizontal sliding limiting rod 16 to extend into the hollow mounting cylinder 9, and then the first rocking rod 7 and the second rocking rod 8 are driven to rock, so that the included angle between the first rocking rod 7 and the second rocking rod 8 is reduced, simultaneously swinging arms 7 and No. two swinging arms 8 drive No. three swinging arms 22 and No. four swinging arms 23 and swing, make the contained angle between No. three swinging arms 22 and No. four swinging arms 23 diminish, be equivalent to the quadrangle and produce deformation this moment, horizontal connecting rod 5 is fixed, will jack up No. two horizontal connecting rod 6 through the deformation of swinging arms 7 and No. two swinging arms 8 and No. three swinging arms 22 and No. four swinging arms 23, also will lengthen the height of a flexible support column 3 and No. two flexible support columns 4 when making No. two horizontal connecting rod 6 risees. After the height adjustment is finished, the pulling handle 24 is released, so that the vertical sliding limiting rod 13 is embedded into the limiting groove 17 again under the action of the restoring force of the compression spring 15 to limit and fix the horizontal sliding limiting rod 16. When the height of the fence is required to be lowered, the same method is used, the horizontal sliding limiting rod 16 extends out of the hollow mounting cylinder body 9 to drive the second horizontal connecting rod 6, the first telescopic supporting column 3 and the second telescopic supporting column 4 to reduce the height, the height of the fence can be conveniently adjusted anytime and anywhere according to actual construction terrain, and therefore the fence is suitable for the actual terrain and is more convenient and practical.
In this embodiment, at first the whole device utilizes flexible support column 3 on circular base 1 and flexible support column 4 No. two on circular base 2 to support to utilize horizontal connecting rod 5 and horizontal connecting rod 6 No. two to carry out joint support to flexible support column 3 and flexible support column 4 No. two. Wherein more telescopic support columns and horizontal connecting rods can be added to increase the length of the fence. When the height of the fence is required to be increased, the vertical sliding limiting rod 13 extending into the first round opening 10 and the second round opening 12 is pulled up by pulling the handle 24, so that the vertical sliding limiting rod 13 leaves the limiting groove 17. At this time, the circular stopper 14 pushes the compression spring 15 to deform. Wherein the portal bracing frame 11 plays a role of supporting the vertical sliding limiting rod 13. Then the rocking handle 21 is shaken to enable the gear 20 in the first strip-shaped opening 19 to rotate, the gear 20 and the rack 18 are matched to drive the horizontal sliding limiting rod 16 to extend into the hollow mounting cylinder 9, and then the first rocking rod 7 and the second rocking rod 8 are driven to rock, so that the included angle between the first rocking rod 7 and the second rocking rod 8 is reduced, simultaneously swinging arms 7 and No. two swinging arms 8 drive No. three swinging arms 22 and No. four swinging arms 23 and swing, make the contained angle between No. three swinging arms 22 and No. four swinging arms 23 diminish, be equivalent to the quadrangle and produce deformation this moment, horizontal connecting rod 5 is fixed, will jack up No. two horizontal connecting rod 6 through the deformation of swinging arms 7 and No. two swinging arms 8 and No. three swinging arms 22 and No. four swinging arms 23, also will lengthen the height of a flexible support column 3 and No. two flexible support columns 4 when making No. two horizontal connecting rod 6 risees. After the height adjustment is finished, the pulling handle 24 is released, so that the vertical sliding limiting rod 13 is embedded into the limiting groove 17 again under the action of the restoring force of the compression spring 15 to limit and fix the horizontal sliding limiting rod 16. When the height of the fence needs to be adjusted down, the same method is used, the horizontal sliding limiting rod 16 extends out of the hollow mounting cylinder 9 to drive the second horizontal connecting rod 6, the first telescopic supporting column 3 and the second telescopic supporting column 4 to reduce the height. Wherein the reflective strips 25 serve to warn pedestrians and vehicles by reflection of light.
Further optimization is made for the above embodiment: in the above embodiment, before the fence height adjustment process is finished, one hand of the worker needs to rotate the shaking handle to drive the gear to rotate and horizontally slide the horizontal movement of the limiting rod 16, the other hand needs to lift the pulling handle 24 all the time to keep the vertical sliding limiting rod to be separated from the limiting groove, so that the smooth height adjustment is ensured. Therefore, it is necessary to further improve the above embodiment, so that the enclosure can be lifted by a single person operating on one side. On the basis of the requirement, the structure of the limit groove is cancelled, only the rack structure on the lower surface of the horizontal sliding limit rod 16 is reserved, and meanwhile, the connection mode of the horizontal sliding limit rod 16 and the second swinging rod 8 on the side part of the horizontal sliding limit rod is changed into 360-degree rotation connection by hinging, and the working principle is as follows: when the locking limiting state is entered, the gear is pulled down, then the horizontal sliding limiting rod 16 is rotated, the side with the rack faces upwards, the pulling handle 24 is lifted upwards to be aligned with the gap of the nearest rack, and then the pulling handle 24 is loosened to enter the locking state; when the lifting state is adjusted, firstly the pulling handle 24 is loosened, then the horizontal sliding limiting rod 16 is rotated, when the surface with the rack is downward, namely the surface with the rack is aligned with the gear below, the pulling handle 24 is loosened, then the gear is lifted to be meshed with the rack, the rocking handle 21 on the gear is rotated, and then the lifting can be realized, because the surface of the pulling handle 24, which is contacted with the horizontal sliding limiting rod 16, is the surface without the limiting groove at the moment, the friction force between the surface and the sliding limiting rod is very small, and the pushing force generated by the tooth-shaped meshing can be ignored. Therefore, only need carry out the rack processing in the one side of horizontal sliding rod in this improvement, saved process and time cost, can also increase its global rigidity, can also realize single unilateral operation in addition, improve lift operating efficiency greatly.
The technical solutions described above only represent the preferred technical solutions of the present invention, and some possible modifications to some parts of the technical solutions by those skilled in the art all represent the principles of the present invention, and fall within the protection scope of the present invention.
