Description

Technical Field

[0001] The utility model relates to the technical field of construction protection, in particular to a building construction protection fence. Background Art

[0002] A guardrail is a railing or fence structure used to isolate and protect a specific area. They are usually used in industry, construction or transportation to restrict people or vehicles from entering dangerous areas to ensure safety. In order to prevent non-staff from entering the construction area and causing injuries during building construction, construction guardrails will be set up around the construction area to block non-staff. Currently, existing construction guardrails are usually integrated structures. They are transported to the installation location by vehicles and installed manually. However, construction guardrails are usually made of metal, which is heavy and difficult to move during manual installation. In order to solve the problem of difficulty in moving when the guardrail is installed, some guardrails with universal wheels or mobile wheels at the bottom have appeared on the market. However, in order to improve the stability of these guardrails during movement, the mobile wheels will be set on the horizontal plates protruding from the main structure. When these protruding horizontal plates and mobile wheels are used for building construction protection beside the road, the guardrails set up beside the road will occupy part of the road space, which will affect the passage of pedestrians and vehicles, and these protruding mobile guardrails will increase the overall volume of the guardrails, which will have a certain impact on the transportation and storage of the guardrails.

[0003] For example, a construction protection device disclosed in the utility model patent with authorization announcement number CN214403031U includes at least two bases, columns are provided on the bases, horizontal bars are provided between adjacent columns, rolling parts are slidably provided on the bases, locking parts for fixing on the bases are provided on the rolling parts, positioning parts for fixing the bases are slidably provided on the bases, and limiting parts for fixing the positioning parts are provided on the bases. This application has the effect of increasing the convenience of moving the guardrails, but this patent will have the problem of protruding bottom plate and too many columns when in use. When it is set beside the road, it will occupy the road space, affecting the passage of pedestrians or vehicles, and the bottom plate is long and cannot be folded, which is not convenient for transportation and storage of the guardrails.

A folding and moving mechanism 5 is installed on each of the two support rods 2. A plurality of reflective strips 7 are fixedly installed on the sides of the two support rods 2. The reflective strips 7 can reflect light at night to remind pedestrians or vehicles of the existence of the guardrail. An inverted U-shaped connecting hook 8 is fixedly installed on the side of the middle part of one of the support rods 2. A connecting tube 9 matching with the connecting hook 8 is fixedly installed on the side of the middle part of the other support rod 2. The two guardrails can be connected to each other through the cooperation of the connecting hook 8 and the connecting tube 9, so that the guardrail can form a continuous and neat appearance, making the entire area look more orderly and beautiful, and improving the environmental quality.

[0017] The folding and moving mechanism 5 includes a moving seat 51, a screw 52, ​​a guide groove 53, a fixed block 54, a rotating plate 55, a support plate 56, a connecting seat 57 and a universal wheel 58. There are four fixed blocks 54, which are respectively fixedly mounted on the two side surfaces of the lower end of the support rod 2, and the opposite sides of the four fixed blocks 54 are respectively rotatably connected to the side surfaces of one end of the two rotating plates 55. The side surfaces of the middle parts of the two rotating plates 55 are fixedly mounted with connecting seats 57, and the bottoms of the outer ends of the two rotating plates 55 are fixedly mounted with universal wheels 58. The guide groove 53 is provided with two The two guide grooves 53 are respectively opened on the two side surfaces of the support rod 2, and the two ends of the screw rod 52 are respectively rotatably connected with the middle part of the top and the bottom of the support rod 2, and one end of the screw rod 52 passes through the screw hole at the top of the moving seat 51. The middle part of the top of the two support rods 2 is rotatably installed with a knob 6, and the lower ends of the two knobs 6 pass through the through holes at the top of the two support rods 2 and are fixedly connected with the upper ends of the two screw rods 52. The side of the knob 6 is provided with an anti-skid pattern, and people can conveniently twist the screw rod 52 to rotate through the knob 6, and the anti-skid pattern on the side of the knob 6 can improve the rotation. The friction force of the button 6 is convenient for use. The two protruding parts on the side of the moving seat 51 are respectively rotatably connected with one end of the two support plates 56. The side surfaces of the other ends of the two support plates 56 are respectively rotatably connected with the opposite sides of the two connecting seats 57. The two support plates 56 are respectively located in the two guide grooves 53. The moving seat 51 is driven to move by the screw 52, ​​so that the moving seat 51 drives one end of the two support plates 56 to move downward, so that the other ends of the two support plates 56 push the two rotating plates 55 to rotate to a horizontal position, so that the universal wheels 58 on the support plates 55 are in contact with the ground. The base 1 is supported off the ground by the universal wheel 58, and the entire guardrail can be easily moved through the universal wheel 58, which is convenient for the mobile installation of the guardrail. After the installation is completed, the screw rod 52 can be twisted in the opposite direction to rotate, so that the screw rod 52 drives one end of the support plate 56 to move upward, and the other end of the support plate 56 drives the rotating plate 55 to rotate upward, so that the rotating plate 55 is attached to the side of the support rod 2, thereby avoiding the rotating plate 55 and the universal wheel 58 from occupying the road and not affecting the passage of vehicles and pedestrians. After the rotating plate is folded, the volume of the entire guardrail is smaller, which is convenient for transportation and storage.

[0018] The working principle of the utility model is as follows: when installing the enclosure in the building construction area, the knob 6 can be twisted to make the knob 6 drive the screw rod 52 to rotate, so that the screw rod 52 drives the movable seat 51 to move downward, so that the movable seat 51 drives the upper ends of the two support plates 56 to move downward, so that the lower ends of the two support plates 56 drive the two connecting seats 57 and the two rotating plates 55 to rotate downward, and in the process of the two rotating plates 55 rotating, the universal wheel 58 on the rotating plate 55 will contact the ground, and as the rotating plate 55 rotates, the universal wheel 58 and the rotating plate 55 will support the base 1 away from the ground. Repeat the above operation so that the base 1 on the other side is also supported off the ground, push the support rod 2 to rotate the universal wheel 58 at the bottom, and move the entire guardrail to the installation position, twist the knob 6 in the opposite direction, so that the knob 6 drives the screw rod 52 to rotate in the opposite direction, and the screw 52 drives the moving seat 51 to rotate in the opposite direction, so that the moving seat 51 drives the support plate 56 to move upward, and the support plate 56 pulls the rotating plate 55 to rotate upward, so that the side of the rotating plate 55 contacts the side of the support rod 2. At this time, the base 1 falls to the ground, and the base 1 can be fixed through the fixing hole 10 on the base 1.

[0019] It is worth noting that the knob 6 in the present invention is a spherical structure, which can be disguised as a decorative ball on the top of the column, thereby preventing passers-by from operating the knob 6 to a certain extent.
