Technical Field

[0001] The utility model relates to the technical field of close-mesh safety nets, in particular to a close-mesh safety net that is easy to roll up. Background Art

[0002] Dense mesh safety net, also known as dense mesh net and dust-proof net, is generally used in construction projects. Its main function is for construction project safety protection. It can effectively prevent various objects in the building from falling freely, thereby producing a buffering effect. Therefore, it is also called "dense mesh building safety vertical net". It is mainly used for the perimeter protection of buildings during construction to prevent people or objects from falling and dust. Most of them are green, some are blue or some other colors.

[0003] According to a disclosed close-mesh safety net that is easy to roll up (publication number: CN216921462U), in the above application, a motor is set to drive the winding roller to rotate, and the close-mesh safety net body is rolled up, so that the safety net can be automatically rolled up.

[0004] However, during actual use of the above-mentioned equipment, the safety net is rolled up by a motor driving the winding shaft, but the rolled up safety net is not easy to separate from the winding roller. At the same time, when the safety net is connected to the winding roller, it is easy to separate from the winding roller, thereby reducing the winding efficiency of the safety net. In view of this, we propose a dense mesh safety net that is easy to roll up. Summary of the invention

[0005] The utility model aims to provide a dense mesh safety net which is easy to roll up, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a close-mesh safety net that is easy to roll up, comprising a safety net, a rolling structure is arranged on the outside of the safety net, and the rolling structure comprises:

[0007] A shell is provided on the outside of the safety net, and the shell is convenient for installing the motor. The inner wall of the shell is fixedly connected with the end of the motor, and the output end of the motor is fixedly connected with the bottom of the support plate. The support plate is convenient for providing support force to the arc plate. The top of the support plate is fixedly connected with the end of the rotating shaft. A slide groove is provided on the upper surface of the support plate, and the inner wall of the slide groove is slidably connected with the bottom of the slider;

[0008] A telescopic rod, a side wall of the rotating shaft is fixedly connected with a fixed end of the telescopic rod, the telescopic rod is convenient for supporting the arc plate, a spring is provided on the outer wall of the telescopic rod, a fixed electromagnet is provided on the outer side of the spring, a movable electromagnet is provided on the outer side of the fixed electromagnet, the side wall of the movable electromagnet is fixedly connected with the inner surface of the arc plate, and a limiting hole is provided on the side wall of the arc plate, the limiting hole is convenient for the safety net to be inserted.

[0009] Preferably, a side of the sliding block away from the supporting plate is fixedly connected to the bottom of the arc-shaped plate.

[0010] Preferably, the spring is sleeved on the outer wall of the rotating shaft, one end of the spring is fixedly connected to the side wall of the rotating shaft, and the other end of the spring is fixedly connected to the inner wall of the arc plate.

[0011] Preferably, the side wall of the fixed electromagnet is fixedly connected to the side wall of the rotating shaft, and the side wall of the movable electromagnet is fixedly connected to the inner surface of the arc plate.

[0012] Preferably, a positioning hole is opened at the top of the arc-shaped plate, the inner wall of the positioning hole is matched with the outer wall of the positioning column, and the top of the positioning column is fixedly connected to the bottom of the fixing plate.

[0013] Preferably, the outer surface of the limiting hole is matched with the inner wall of the safety net.

[0014] Compared with the prior art, the utility model provides a dense mesh safety net that is easy to roll up, and has the following beneficial effects:

[0015] 1. The close-mesh safety net that is easy to roll up is convenient for the safety net to be inserted by setting limited holes. The motor drives the support plate so that the rotating shaft drives the two groups of arc plates to rotate to roll up the safety net. After the rolling is completed, the two groups of arc plates are brought close to each other through the attraction of the fixed electromagnet and the movable electromagnet. At the same time, the slider cooperates with the slide groove to ensure the stability of the arc plates when they are close to each other. The telescopic rod and the spring can ensure that the arc plates are in a horizontal state when they are close to the rotating shaft, so that the arc plates are kept away from the rolled-up safety net, which is convenient for the rolled-up safety net to be separated from the two groups of arc plates, thereby improving the convenience of taking the safety net, and then the safety net with a larger area can be automatically rolled up when it needs to be rolled up and transported, without manual rolling, thereby improving the rolling efficiency of the safety net.

[0016] 2. The dense-mesh safety net that is easy to roll up is provided with positioning holes and positioning columns, so that the fixing plate can close or release the opening of the limiting holes, so that the limiting holes can prevent the safety net from separating from the arc plate when the safety net is limited, thereby improving the stability of the safety net connected to the arc plate before rolling up.
