Description

Technical Field

[0001] The utility model relates to the technical field of protective nets, in particular to an adjustable protective net for building safety. Background Technique

[0002] The protective net for construction refers to the protective net set up to protect the safety of construction workers during the construction process. The protective net can effectively prevent construction workers from falling from a height, thereby reducing the occurrence of safety accidents. The protective net for construction is usually made of materials such as polyethylene and polypropylene, and has the advantages of high strength, wear resistance, corrosion resistance, and aging resistance. The installation of the protective net usually adopts two methods: hanging type or fixed type, and the specific installation method should be selected according to the actual situation of the construction site.

[0003] During construction, it may be necessary to install a protective net outdoors at a high altitude. When constructing at a relatively high place and installing the protective net outside the stairs, it increases the danger of construction for the staff. Most of the existing protective nets still require outdoor installation by the staff, which is neither safe nor convenient. Moreover, when the protective net is stored, it will be entangled together and difficult to untie for the next use. Summary of the Invention

[0004] The purpose of the utility model is to provide an adjustable protective net for building safety to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an adjustable protective net for building safety, including a winding box and a bracket. The winding box is hinged to the bracket. A vertical plate is fixedly connected to the top surface of the winding box. An installation plate is fixedly connected to the surface of the vertical plate. A square plate penetrates and is hinged to the top end of the vertical plate. A control part and an adjustment part are arranged inside the bracket. The control part includes:

[0006] A rotating rod, which penetrates the winding box and is rotatably connected. A protective net and a scroll spring are fixedly connected to the surface of the rotating rod. The moving block will drive the clamping strip to move together through the connecting block, and the arc surface of the clamping strip will abut against the cogs, thereby forcing the connecting block to contract into the moving block. One end of the scroll spring away from the rotating rod is fixedly connected to the inner wall of the winding box. One end of the protective net away from the rotating rod is fixedly connected to a connecting strip;

[0007] A moving block, which penetrates the bracket and is slidably connected. One side of the moving block close to the connecting strip is fixedly connected to the connecting strip. A hinge block is fixedly connected to the top surface of the moving block. An expansion rod is hinged inside the hinge block. A jack is opened on the surface of the expansion rod. The expansion rod penetrates and is slidably connected to a connecting column. The top surface of the connecting column is fixedly connected to the bottom surface of the square plate. The connecting column penetrates and is rotatably connected to a rotating sleeve.

[0008] Preferably, a first spring is fixedly connected to the top surface of the telescopic rod, and the top end of the first spring is fixedly connected to the inner side of the connecting column.

[0009] Preferably, a fixed block is fixedly connected to the bottom surface of the connecting column. A sliding groove is formed on the surface of the fixed block. A rotating plate is fixedly connected to the bottom surface of the rotating sleeve. An arc-shaped groove is formed on the surface of the rotating plate.

[0010] Preferably, a sliding rod is slidably connected to the inner side of the arc-shaped groove. When the rotating rod rotates, the scroll spring will be tightened. When the coverage area of the protective net is determined, stop pulling the moving block and rotate the rotating sleeve. When the rotating sleeve rotates, it will drive the rotating plate to rotate together, so that the arc-shaped groove formed on the surface of the rotating plate touches the sliding rod and moves together. The top surface of the sliding rod is fixedly connected with a slider. The slider penetrates through the sliding groove, and the sliding rod penetrates through the arc-shaped groove.

[0011] Preferably, a clamping block is fixedly connected to the top surface of the sliding rod. The arc-shaped groove formed on the surface of the rotating plate touches the sliding rod and moves together, and the sliding rod will drive the slider to slide along the sliding groove, so that the clamping block is inserted into the jack. The cross-section of the clamping block is the same as the shape of the jack. A clamping tooth is fixedly connected to the inner side of the bracket.

[0012] Preferably, the adjusting part includes a pull rod. The pull rod penetrates through the moving block and is slidably connected. A pull block is fixedly connected to the right side of the pull rod. A second spring is fixedly connected between the pull block and the moving block. Pull the pull block to make the pull block pull the elastic piece so that the connecting block drives the clamping strip to contract and no longer be clamped with the clamping tooth, and then the moving block can be pushed back to complete the reset.

[0013] Preferably, a connecting block penetrates through and is slidably connected to the inner side of the moving block. A clamping strip is fixedly connected to the bottom surface of the connecting block. The mounting plate is installed at the position to be protected through bolts and other mounting parts, and then the moving block is pulled. The moving block will drive the clamping strip to move together through the connecting block. An elastic piece is hinged between the clamping strip and the pull rod. The number of the connecting blocks is two groups, and a short rod penetrates between the two groups of connecting blocks. At the same time, a third spring is fixedly connected between the two groups of connecting blocks.

[0014] Compared with the prior art, the utility model provides an adjustable protective net for building safety, which has the following beneficial effects:

[0015] 1. For the adjustable protective net for building safety, when the coverage area of the protective net is determined, stop pulling the moving block and rotate the rotating sleeve. When the rotating sleeve rotates, it will drive the rotating plate to rotate together, causing the arc-shaped groove formed on the surface of the rotating plate to contact the sliding rod and move it together. The sliding rod will drive the slider to slide along the sliding groove, and then the clamping block will be inserted into the jack, so that the telescopic rod cannot be telescoped with the connecting column for fixation, making the bracket and the moving block unable to move further, thus completing the installation. When installing at high altitude, the square plate can be toggled, so that the connecting column drives the telescopic rod to rotate together, and it can also push the moving block to move, avoiding the increased danger of outdoor installation of the protective net by workers at high altitude.

[0016] 2. For the adjustable protective net for building safety, after the use of the protective net is completed, remove the mounting plate and pull the pulling block, so that the pulling block pulls the elastic piece, causing the connecting block to drive the clamping strip to contract and no longer be clamped with the teeth, and then the moving block can be pushed back to complete the reset. In addition, the bracket hinged to the winding box can be lifted, and the telescopic rod will rotate at the position of the hinge block, so that the bracket can be retracted, which is more convenient for storage.

[0024] As Figures 1 - 6 shown, the utility model provides a technical solution: an adjustable protection net for building safety, which includes a winding box 1 and a bracket 7. The winding box 1 is hinged to the bracket 7. A vertical plate 4 is fixedly connected to the top surface of the winding box 1. An installation plate 6 is fixedly connected to the surface of the vertical plate 4. The top end of the vertical plate 4 penetrates and is hinged to a square plate 5. A control part 2 and an adjusting part 3 are arranged inside the bracket 7. The control part 2 includes: a rotating rod 21, a protection net 22, a volute spring 23, a connecting strip 24, a moving block 25, a hinged block 26, a telescopic rod 27, a connecting column 28, a first spring 29, a jack 210, a rotating sleeve 211, a fixed block 212, a chute 213, a slider 214, a clamping block 215, a sliding rod 216, a rotating plate 217, an arc-shaped groove 218, and a tooth 219.

[0025] The rotating rod 21 penetrates through the winding box 1 and is rotatably connected. A protective net 22 and a volute spring 23 are fixedly connected to the surface of the rotating rod 21. The moving block 25 will drive the latch 35 to move together through the connecting block 34, and the arc surface of the latch 35 will abut against the latch teeth 219, thereby forcing the connecting block 34 to contract into the moving block 25 and compressing the spring three 38. When the moving block 25 moves, it will pull the connecting bar 24 to move together, thereby stretching the protective net 22 wound on the rotating rod 21. One end of the volute spring 23 away from the rotating rod 21 is fixedly connected to the inner wall of the winding box 1. One end of the protective net 22 away from the rotating rod 21 is fixedly connected to the connecting bar 24. The moving block 25 penetrates through the bracket 7 and is slidably connected. The side of the moving block 25 close to the connecting bar 24 is fixedly connected to the connecting bar 24. A hinge block 26 is fixedly connected to the top surface of the moving block 25. An expansion rod 27 is hinged inside the hinge block 26. A jack 210 is provided on the surface of the expansion rod 27. The expansion rod 27 penetrates through and is slidably connected to a connecting column 28. The top surface of the connecting column 28 is fixedly connected to the bottom surface of the square plate 5. The connecting column 28 penetrates through and is rotatably connected to a rotating sleeve 211. A spring one 29 is fixedly connected to the top surface of the expansion rod 27. The top end of the spring one 29 is fixedly connected to the inside of the connecting column 28. A fixed block 212 is fixedly connected to the bottom surface of the connecting column 28. A sliding groove 213 is provided on the surface of the fixed block 212. A rotating plate 217 is fixedly connected to the bottom surface of the rotating sleeve 211. An arc groove 218 is provided on the surface of the rotating plate 217. A sliding rod 216 is slidably connected inside the arc groove 218. When the rotating rod 21 rotates, it will tighten the volute spring 23. When the covering area of the protective net 22 is determined, stop pulling the moving block 25 and rotate the rotating sleeve 211. When the rotating sleeve 211 rotates, it will drive the rotating plate 217 to rotate together, so that the arc groove 218 provided on the surface of the rotating plate 217 abuts against the sliding rod 216 and moves together. The top surface of the sliding rod 216 is fixedly connected to a slider 214. The slider 214 penetrates through the sliding groove 213. The sliding rod 216 penetrates through the arc groove 218. A clamping block 215 is fixedly connected to the top surface of the sliding rod 216. The arc groove 218 provided on the surface of the rotating plate 217 abuts against the sliding rod 216 and moves together, and the sliding rod 216 will drive the slider 214 to slide along the sliding groove 213, so that the clamping block 215 is inserted into the jack 210, thereby fixing the expansion rod 27 and the connecting column 28 so that they cannot expand and contract, and making the bracket 7 and the moving block 25 unable to move further. The cross-section of the clamping block 215 is the same as the shape of the jack 210. Latch teeth 219 are fixedly connected to the inside of the bracket 7. The adjusting part 3 includes a pull rod 31. The pull rod 31 penetrates through the moving block 25 and is slidably connected. A pull block 32 is fixedly connected to the right side of the pull rod 31. A spring two 33 is fixedly connected between the pull block 32 and the moving block 25. After the protective net 22 is used up, remove the mounting plate 6, pull the pull block 32, so that the pull block 32 pulls the elastic piece 36 to drive the connecting block 34 to drive the latch 35 to contract and no longer be clamped with the latch teeth 219, and then the moving block 25 can be pushed back to complete the reset.A connecting block 34 penetrates through and is slidably connected to the inner side of the moving block 25. A clamping strip 35 is fixedly connected to the bottom surface of the connecting block 34. The mounting plate 6 is mounted at a position to be protected by bolts or other mounting members. Then, the moving block 25 is pulled. The moving block 25 will drive the clamping strip 35 to move together through the connecting block 34. An elastic piece 36 is hinged between the clamping strip 35 and the pull rod 31. The number of the connecting blocks 34 is two groups, and a short rod 37 penetrates between the two groups of connecting blocks 34. At the same time, a third spring 38 is fixedly connected between the two groups of connecting blocks 34.

[0026] Based on the above implementation manner, the mounting plate 6 is mounted at a position to be protected by bolts or other mounting members. Then, the moving block 25 is pulled. The moving block 25 will drive the clamping strip 35 to move together through the connecting block 34. The arc surface of the clamping strip 35 will abut against the clamping teeth 219, thereby forcing the connecting block 34 to contract into the moving block 25 and compressing the third spring 38. When the moving block 25 moves, it will pull the connecting strip 24 to move together, thereby stretching the protective net 22 wound around the rotating rod 21. When the rotating rod 21 rotates, the volute spring 23 will be tightened. When the coverage area of the protective net 22 is determined, stop pulling the moving block 25 and rotate the rotating sleeve 211. When the rotating sleeve 211 rotates, it will drive the rotating plate 217 to rotate together, so that the arc-shaped groove 218 formed on the surface of the rotating plate 217 abuts against the sliding rod 216 to move together. The sliding rod 216 will drive the slider 214 to slide along the sliding groove 213, and then the clamping block 215 is inserted into the insertion hole 210, so that the telescopic rod 27 cannot expand and contract with the connecting column 28 for fixation, so that the bracket 7 and the moving block 25 cannot move any further, thus completing the installation. If it is installed at a high altitude, the square plate 5 can be toggled, so that the connecting column 28 drives the telescopic rod 27 to rotate together, and it can also push the moving block 25 to move, avoiding the risk of increasing the danger for the staff to install the protective net 22 outdoors at a high altitude.

[0027] After the protective net 22 is used up, remove the mounting plate 6 and pull the pulling block 32, so that the pulling block 32 pulls the elastic piece 36 to make the connecting block 34 drive the clamping strip 35 to contract and no longer be clamped with the clamping teeth 219. Then, the moving block 25 can be pushed back to complete the reset. The bracket 7 hinged to the winding box 1 can be lifted, and the telescopic rod 27 will rotate at the position of the hinge block 26, so that the bracket 7 is retracted, which is more convenient for storage.

[0028] The above text generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
