Description

Technical Field

[0001] The utility model relates to the technical field of protective nets, in particular to a foldable and storable protective net. Background Technique

[0002] A protective net is a labor protection and safety tool often used in engineering construction. It has a wide range of applications. It plays a role in protecting the construction site, isolating passers-by, preventing non-construction personnel from entering the site, and protecting the safety of non-staff.

[0003] The existing protective net usually consists of connecting columns and a whole piece of net body. When in use, the net piece is fixedly connected between adjacent connecting columns, and then the connecting columns are fixed to the ground through expansion bolts, so that the building protective net protects the construction area of the construction site and prevents non-construction personnel from entering the construction area, thus avoiding accidents. However, this kind of protective net has a single structure, is not easy to fold and tidy up after storage and transportation, and during the installation process, due to the large overall size of the net body, handling and installation are not convenient enough, and it cannot be freely extended according to the use scenario, with great limitations.

[0004] Therefore, the technical personnel in this field provide a foldable and storable protective net to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a foldable and storable protective net is proposed.

At the same time, by means of the ground nails under the sliding base and inserting the ground nails into the soil, the protective net can be firmly erected on the ground. Moreover, the protective net can be arbitrarily folded through the folding plate between the first net body and the second net body. At the same time, by rotating the first handwheel, any one of the net bodies can be disassembled for replacement, providing more convenient operation and assembly for construction workers.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A foldable and retractable protective net, including a first connecting column, a second connecting column, two first net bodies and two second net bodies. At the middle of the opposite sides of the lower end faces of the two first net bodies and the second net bodies, sliding bases are slidably arranged. At the middle of the lower end faces of the plurality of sliding bases, ground nails are fixedly arranged.

[0008] Further, chutes are opened on both sides of the first connecting column and the second connecting column. One side of each of the two first net bodies is respectively embedded in the two chutes;

[0009] Through the above technical solutions, more combinations of the net bodies can be achieved through the opened chutes.

[0010] Further, fixing blocks are fixedly arranged on one side of each of the two first net bodies close to the first connecting column and the second connecting column;

[0011] Through the above technical solutions, the net bodies and the connecting columns can be fixedly connected through the fixing blocks and will not easily come off.

[0012] Further, threaded grooves are opened at the positions near both sides of the front ends of the plurality of folding plates, and screws are threadedly sleeved in the threaded grooves. At one end of each of the plurality of screws, a first handwheel is fixedly arranged;

[0013] Through the above technical solutions, rotating the handwheel to drive the screw can make the racks in the folding plates contract into the folding plates.

[0014] Further, the plurality of gears are fixedly sleeved on the screws. Ball grooves are opened at the positions near the lower end faces of the plurality of first racks. Ball grooves are opened at the positions near the upper end faces of the plurality of second racks;

[0015] Through the above technical solution, the gear mainly drives the contraction movement of the rack, and the bead grooves on the rack are used to prevent the rack from contracting easily when the gear stops rotating.

[0016] Furthermore, a plurality of V-shaped grooves are formed on the outer surface of the ground nail, and the folding plate is movably arranged between the upper and lower ends of the clamping block.

[0017] Through the above technical solution, the V-shaped grooves are formed to prevent the ground nail from being easily pulled out after being buried in the ground, playing a fixing role, and the folding plate is used for folding between the net bodies.

[0018] Furthermore, grooves are formed at one ends of the clamping blocks close to the folding plate, and the first rack and the second rack are respectively movably arranged in the grooves close to the upper and lower ends of the folding plate.

[0019] Through the above technical solution, when the net body rotates, the clamping block will rotate together, so that the net body can be folded.

[0020] The utility model has the following beneficial effects:

[0021] 1. For the foldable and retractable protective net proposed by the utility model, it is connected by the screws inside the upper and lower ends of the two connecting columns and the fixing blocks on one side of the first net body, so that a plurality of net bodies are combined to form a larger protective net. It can be extended and shortened according to the size of the construction site, making it more flexible to use and having less limitation. Then, by installing the sliding base and the ground nail at the lower end of the sliding base, the protective net can be firmly fixed on the ground and will not shake easily.

[0022] 2. For the foldable and retractable protective net proposed by the utility model, the first net body and the second net body are assembled into a whole through the clamping blocks and the folding plates on one side. After the construction is completed, it can be directly folded, thus reducing the volume of the protective net, saving the handling time of workers, and being more convenient for storage, saving a certain amount of space. At the same time, by rotating the first handwheel, the rack inside the folding plate can be contracted, and the damaged net body can be disassembled and replaced with a new net body, so as to achieve more convenient assembly.

Springs 12 are movably arranged inside multiple clamping blocks 11. Ball bearings 13 are movably arranged inside multiple clamping blocks 11. Through the ball bearings 13, the first rack 14 and the second rack 15 can be clamped inside the clamping blocks 11 and will not easily contract. Folding plates 18 are movably arranged on the opposite sides of the two first net bodies 3 and the second net bodies 4 in pairs. Through the folding plates 18, the first net body 3 and the second net body 4 can be folded between them. Second racks 15 are penetrated through both sides at the upper end faces of multiple folding plates 18. First racks 14 are penetrated through both sides at the lower end faces of multiple folding plates 18. Gears 16 are meshed between multiple first racks 14 and second racks 15. By rotating the gears 16, the first racks 14 and the second racks 15 can be driven to contract.

[0032] Chute 19 is provided on both sides of the first connecting column 1 and the second connecting column 2. One side of each of the two first mesh bodies 3 is respectively embedded in the two chutes 19.
