Description

Technical Field

[0001] The present invention relates to the technical field of protective nets, and in particular to an outer protective net suitable for a climbing frame. Background Art

[0002] A climbing frame is a support frame used for industrial equipment, buildings or other structures. It is usually used to provide a support platform for workers to perform high-altitude operations, maintenance, installation, etc. A climbing frame is generally composed of beams, columns and connectors, which can lift workers to the required height and provide a safe working platform. A protective net is a mesh structure set around a climbing frame or other high-altitude working platform. When working at height or on a climbing frame, a protective net is usually installed on the outside of the climbing frame for protection. The protective net can ensure that workers do not accidentally fall when working at height, and protect the personnel and site equipment below from possible falling objects.

[0003] In large-scale buildings, protective nets made of materials such as polyethylene mesh are used to shield and protect climbing frames. The protective nets can be recycled after use, but it is inconvenient to recycle large-scale protective nets. A large number of protective nets are piled up together after being disassembled, which is inconvenient to sort out, and recycling takes up storage space. Therefore, those skilled in the art provide an outer protective net suitable for climbing frames to solve the problems raised in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to address the problems existing in the background technology and to provide an outer protective net suitable for a climbing frame.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an outer protective net suitable for a climbing frame, comprising a storage box, a protective net, a roller and two pressure plates, wherein a roller is rotatably installed inside the storage box, and the protective net is rolled up on the outer wall of the roller, and mounting holes are provided inside the upper and lower ends of the protective net, and two pressure plates are provided inside one side of the storage box, and the two pressure plates are connected to the storage box through a compression spring, and one end of the two pressure plates is provided with equidistantly distributed pressure nails, a support plate is provided on the inner wall of one side of the lower end of the storage box, and a travel groove is provided at one end of the storage box.

[0006] Preferably, the outer wall of the roller is sleeved with symmetrically distributed limiting rings, the limiting rings are located at both ends of the protective net, and a rotary handle is provided on the upper end of the roller. When the roller reels the protective net, the limiting rings are used to limit the protective net, so that the reeled protective net is neat, and it is convenient to apply a rotational force to the roller by grasping the rotary handle.

[0007] Preferably, a pressure plate 1 is provided on one side of the storage box, and symmetrically distributed springs are provided between the pressure plate 1 and the inner wall of the storage box. The pressure plate 1 is elastically supported by the spring, and then the protective net rolled up on the outer wall of the roller is pressed by the elastically supported pressure plate pair to ensure the stability of the protective net after rolling up.

[0008] Preferably, one end of the storage box is provided with symmetrically distributed through holes 1, and one end of the pressure plate is provided with a guide rod located inside the spring and slidably inserted into the through hole 1. During the expansion and contraction of the spring, the guide rod slides inside the through hole 1 to limit the spring during the expansion and contraction process, thereby preventing the spring from deviating outward during the expansion and contraction process.

[0009] Preferably, the pressure plate is internally rotatably mounted with equally spaced balls, so that the balls are in sliding contact with the outer wall of the protective net wound by the roller, thereby reducing the friction and resistance of the protective net when passing through the pressure plate.

[0010] Preferably, the compression spring is provided with a mutually plugged positioning tube and a positioning rod, one end of the positioning rod is connected to the second pressure plate, and one end of the positioning tube is connected to the inner wall of the storage box. During the longitudinal expansion and contraction of the compression spring, the positioning rod slides inside the positioning tube to guide the compression spring to prevent the compression spring from deviating outward.

It is convenient to apply a rotational force to the screw rod 1 by grasping the rotating rod 1, and the screw rod 1 rotates inside the rotating seat to prevent the rotational force of the screw rod 1 from acting on the pressure plate 2, so that the pressure plate 2 is applied with a push-pull force by the screw rod 1.

[0012] Preferably, a rubber pad is provided at one end of the support plate opposite to the pressure nail. When the cone nail moves toward the support plate, the rubber pad allows the cone nail to penetrate, thereby improving the fit between the pressure nail and the support plate.

[0013] Preferably, the rear end of the storage box is provided with symmetrically distributed side panels and fixed panels and two sets of symmetrically distributed guide rails, and a clamping plate is slidably mounted on the upper end of the guide rail. The clamping plate is longitudinally supported by the guide rail.

[0014] Preferably, a bearing is provided at one end of the clamping plate, a screw hole is provided inside the side plate, a screw rod 2 is threadedly installed inside the screw hole, a rotating rod 2 is provided at one end of the screw rod 2, one end of the screw rod 2 is rotatably inserted into the bearing, a slot is provided inside the fixing plate, and a plug plate corresponding to the slot is provided at one end of the clamping plate. The rotating rod 2 is grasped to drive the screw rod 2 to rotate, and the rotational force of the screw rod 2 acts on the inside of the bearing, thereby driving the pressure plate to move longitudinally.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention installs the protective net of the climbing frame inside the storage box, extends the rolled protective net by rolling it up, and fixes it on the climbing frame, controls the length of the protective net according to the needs of use, does not need to cut the protective net, and can meet the needs of the protective net of the climbing frame by using multiple storage boxes. The used protective net can be directly rolled up into the storage box, which makes the protective net easy to organize and realizes the convenient recovery of the protective net. In addition, the storage space occupied by the protective net is reduced during the storage process. BRIEF DESCRIPTION OF THE DRAWINGS
