Description

Technical Field

[0001] This utility model relates to the field of construction engineering, and in particular to an adjustable safety fence. Background Technology

[0002] In construction engineering, safety fences are crucial facilities for ensuring safety at construction sites. They are primarily used to demarcate construction areas, isolate hazardous environments, guide the passage of personnel and vehicles, and prevent unauthorized personnel from entering the work area and causing safety accidents. However, when carrying out partial construction inside large factories or cleanrooms, the boundaries between safety passages and construction areas need to be adjusted daily or even hourly according to the work progress. Simultaneously, isolation measures must be sturdy and reliable to prevent fence collapse due to collisions; conventional fences are insufficient to meet these requirements.

[0003] An adjustable safety fence according to existing patent CN213144092U includes posts and supports. A fixing block is installed on the post, and the fixing block is fixedly connected to the support by bolts. Four rotating cylinders are rotatably installed on the post, and the four rotating cylinders form a rotating part in pairs. The fixing block is installed on one side of the rotating cylinder. During assembly, the fence can not only be arranged in a straight line or square, but also adjusted and fixed at an angle according to actual construction needs. However, the individual fence sections cannot be rotated or adjusted; that is, overall adjustment must be done on a per-fence basis. In practical use, if the fence needs to be arranged in a circle, it will lead to inconvenience in overall use.

[0004] Therefore, it is necessary to propose an adjustable safety fence to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide an adjustable safety fence that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An adjustable safety fence includes a first base and a second base, and fixed posts fixedly connected above the first base and the second base. The surfaces of the fixed posts are symmetrically rotatably connected to first rotating posts. Rotating blocks are symmetrically arranged between two first rotating posts. First vertical posts are fixedly connected between two first rotating posts. Two second vertical posts are fixedly connected between each pair of four rotating blocks. First connecting blocks are rotatably connected between the first rotating posts and the rotating blocks. Second connecting blocks are rotatably connected between two rotating blocks. Adjustment posts are rotatably connected to the surfaces of both the first connecting blocks and the second connecting blocks. Both ends of the surface of the adjusting column are provided with spiral grooves, and protrusions are installed on the walls of the spiral grooves. A fixed rod is fixedly connected to the end face of the protrusion away from the spiral groove. A movable sleeve is fixedly connected to the surface of the fixed rod. Both movable sleeves are sleeved on both ends of the adjusting column. Multiple limiting grooves are provided on the surfaces of the first rotating column and the rotating block. Limiting blocks are symmetrically fixedly connected to the surfaces of the movable sleeves close to the surfaces of the first rotating column and the rotating block.

[0007] Preferably, the plurality of limiting grooves are uniformly arranged in a ring on the surfaces of the first rotating column and the rotating block.

[0008] Preferably, the movable sleeve has a positioning groove on the end face away from the first connecting block and the second connecting block, and a positioning rod is slidably connected to the groove wall of the positioning groove, and a plurality of positioning rods are respectively fixedly connected to the first connecting block and the second connecting block.

[0009] Preferably, an anti-slip pad is fixedly connected to the center of the surface of the adjusting column.

[0010] Preferably, a stop block is fixedly connected to the end of the spiral groove wall away from the first connecting block and the second connecting block.

[0011] Preferably, reflective stickers are adhered to the surfaces of both the first rotating column and the rotating block.

[0012] Beneficial effects Compared with the prior art, the present invention has the following beneficial effects: 1. The safety fence for this construction project can be adjusted at multiple points on the overall surface by setting the first rotating column and rotating block. The angle can be adjusted at multiple points by adjusting the rotation of the adjusting column. Multiple fences can be arranged into a circle, which is convenient to use. After the overall surface is adjusted at multiple points, it can be folded for easy access.

[0013] 2. The safety fence for this construction project, by rotating the adjusting column, causes relative movement between the protrusion and the spiral groove, thereby adjusting the movement of the movable sleeve, so that the limiting block and the limiting groove can be engaged or disengaged. According to the actual use, the rotation of the first rotating column or the connecting block can be adjusted. The engagement between the limiting block and the limiting groove is used to limit the rotation of the first rotating column and the connecting block, ensuring the stability of the whole after the angle is adjusted.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figures 1 to 5 An adjustable safety fence includes a first base 1 and a second base 2 and a fixed post 3 fixedly connected above the first base 1 and the second base 2. The surface of the fixed post 3 is symmetrically rotatably connected to a first rotating post 4. Rotating blocks 5 are symmetrically arranged between two first rotating posts 4. A first vertical post 6 is fixedly connected between each pair of four first rotating posts 4. A second vertical post 7 is fixedly connected between two rotating blocks 5. A first connecting block 8 is rotatably connected between the first rotating post 4 and the rotating block 5. A second connecting block 9 is rotatably connected between two rotating blocks 5. Adjusting posts 10 are rotatably connected to the surfaces of the first connecting block 8 and the second connecting block 9. Both ends of the adjusting column 10 are provided with spiral grooves 11. Protrusions 12 are fitted onto the walls of the spiral grooves 11. A fixing rod 13 is fixedly connected to the end face of the protrusion 12 away from the spiral groove 11. Movable sleeves 14 are fixedly connected to the surface of the fixing rod 13. Two movable sleeves 14 are fitted onto both ends of the adjusting column 10. Multiple limiting grooves 15 are provided on the surfaces of the first rotating column 4 and the rotating block 5. Limiting blocks 16 are symmetrically fixedly connected to the surfaces of the movable sleeves 14 near the first rotating column 4 and the rotating block 5. The clearance parameters between the protrusions 12 and the spiral grooves 11 can be calculated using conventional methods to prevent the protrusions 12 from dislodging. The spiral grooves 11 are made of wear-resistant material to improve their service life. Furthermore, in areas with high levels of mud, sand, or dust, the limiting grooves 15, limiting blocks 16, and movable sleeves 14 need to be protected using conventional methods to prevent locking failure due to jamming and ensure reliable operation. However, no protection is required when used in cleanrooms.

[0018] Specifically, the first base 1 and the second base 2 are made of cast iron or steel to provide sufficient weight and stability to prevent the fence from tipping over due to wind or impact when used outdoors. The bases can be fixed to the ground with bolts or counterweights (not shown in the figure) to enhance overall safety. Fixed posts 3 are fixedly connected to the upper ends of the first base 1 and the second base 2, forming the upright support frame of the fence; the fixed posts 3 are vertically installed on the bases, and their surfaces are provided with rotating connection points for installing the first rotating posts 4. The first rotating posts 4 are symmetrically rotatably connected to the surface of the fixed posts 3 and can rotate in the horizontal plane; each first rotating post 4 is connected to the fixed post 3 via a bearing or hinge to achieve smooth rotation. Rotating blocks 5 are located between the first rotating posts 4 and are also installed via a rotating connection. The rotating blocks 5 are similar to the first rotating posts 4, but with a more flexible position, and are used to connect the second vertical post 7 and the connecting block 5.

[0019] It should be noted that, depending on the actual use, adjusting the rotation of the adjusting column 10 causes relative movement between the protrusion 12 and the spiral groove 11, which in turn drives the movable sleeve 14 to move, separating the limiting block 16 from the limiting groove 15. Then, adjusting the rotation of the first rotating column 4 or the connecting block, after the adjustment is completed, adjusting the rotation of the adjusting column 10 in the opposite direction causes relative movement between the protrusion 12 and the spiral groove 11 again, which in turn drives the movable sleeve 14 to move, and the limiting block 16 and the limiting groove 15 re-engage, limiting the first rotating column 4 or the connecting block. The angle can be adjusted at multiple points on the overall surface by adjusting the rotation of the adjusting column 10 separately. Multiple fences can be arranged into a circle, which is convenient to use. After the overall surface is adjusted at multiple points, it can be folded for easy access, greatly simplifying the operation process for construction personnel.

[0020] Furthermore, this adjustable safety fence is not intended to replace all traditional fences, but is specifically designed to address isolation and protection needs in complex scenarios. It is primarily used when conducting partial construction within large factories or cleanrooms, where the boundaries between safety passages and construction areas need to be adjusted daily or even hourly according to the work progress. Simultaneously, the isolation measures must be sturdy and reliable to prevent fence collapse due to collisions.

[0021] Multiple limiting grooves 15 are evenly arranged in a ring on the surfaces of the first rotating column 4 and the rotating block 5.

[0022] The movable sleeve 14 has a positioning groove 17 on the end face away from the first connecting block 8 and the second connecting block 9. The positioning groove 17 is slidably connected to the groove wall of the positioning groove 17, and multiple positioning rods 18 are fixedly connected to the first connecting block 8 and the second connecting block 9 respectively. It should be noted that the positioning groove 17 and the positioning rod 18 can limit the rotation of the movable sleeve 14, preventing the adjustment column 10 from rotating and causing the movable sleeve 14 to rotate, thus ensuring the stability of the movable sleeve 14 during the position adjustment process.

[0023] An anti-slip pad 19 is fixedly connected to the middle of the surface of the adjusting column 10; It should be noted that the anti-slip pad 19 is designed to facilitate the rotation and adjustment of the adjusting column 10, preventing slippage during the adjustment process.

[0024] A stop block 20 is fixedly connected to the end of the spiral groove 11 away from the first connecting block 8 and the second connecting block 9; It should be noted that the stop 20 is designed to prevent the protrusion 12 from separating from the spiral groove 11.

[0025] Reflective stickers 21 are adhered to the surfaces of the first rotating column 4 and the rotating block 5; It should be noted that the reflective sticker 21 is designed to indicate the location of the barrier to the driver when illuminated by vehicle headlights at night.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
