[0021] In the description of the present utility model, it should also be noted that unless otherwise clearly defined and limited, if the terms "set", "installed", "connected", "connected" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] The following is a detailed description of the present utility model in conjunction with Figures 1 to 3 the following.

[0023] A high-altitude protection net for construction includes a main body 1. On one side of the main body 1, a support frame 101 is provided. On the side of the support frame 101 opposite to the main body 1, a connecting rod 2 is provided. Between the connecting rods 2, a safety net 201 is provided. Inside the connecting rod 2, a winding cavity 203 is provided. Inside the winding cavity 203, a winding roller 2031 is provided. Between the connecting rods 2, a buffer strip 202 is connected by the winding roller 2031. On one side of the support frame 101, a lifting assembly is provided. The connecting rod 2 is lifted along the support frame 101 through the lifting assembly. On one side of the bottom of the winding cavity 203, an opening is provided. The buffer strip 202 is wound and connected to the side wall of the winding roller 2031. The two ends of the winding roller 2031 are connected by torsion springs. The buffer strip 202 is made of rubber material.

[0024] First, through the connecting piece on one side of the main body 1, it is connected to the side of the construction building. Then, through the connecting rod 2 on the support frame 101, the safety net 201 is connected between the main body 1 and the support frame 101, so as to form an extended protection measure outside the construction building to prevent construction workers or construction materials from falling.

[0025] At the same time, when a heavy object falls onto the safety net 201, the impact of the falling heavy object will force the safety net 201 to deform and fall downward. When the safety net 201 deforms and sinks downward, it will contact the buffer strip 202 to apply pressure. Through the elasticity of the buffer strip 202, it will adapt to the deformation of the safety net 201. At the same time, it can also slow down the impact of the heavy object when falling through the elastic force. When continuously deforming and falling, it will apply pressure to the buffer strip 202 so that its two ends will be stretched out from the winding roller 2031. The buffer strip 202 is wound and connected to the winding roller 2031. When pulling the buffer strip 202 to extend, it will drive the winding roller 2031 to rotate. The two ends of the winding roller 2031 are connected by torsion springs. Through the reset of the torsion springs, a certain stretching reset will be performed on the buffer strip 202, thereby further reducing the impact of the heavy object falling and extending the length to adapt to the deformation range.

[0026] Further, the lifting component includes a sliding groove 1011, a pin hole 1012, a pin 1013, and a slider 204. The sliding groove 1011 is provided on one side of the support frame 101. The pin hole 1012 is provided on the side of the support frame 101 away from the sliding groove 1011. The pin 1013 is connected in the pin hole 1012. The slider 204 is provided on one side of the connecting rod 2. The slider 204 cooperates with the sliding groove 1011. The pin holes 1012 are a plurality of holes arranged on one side of the support frame 101. The pin holes 1012 communicate with the sliding groove 1011. The side wall of the pin 1013 is thread-matched with the inner wall of the pin hole 1012, and the pin 1013 penetrates through the pin hole 1012 and cooperates with the groove on one side of the slider 204.

[0027] Finally, when setting up the safety net 201, the position of the connecting rod 2 on the support frame 101 can be adjusted to make it lift along the support frame 101 through the slider 204, so as to adjust the inclination angle of the safety net 201, enabling the safety net 201 to adjust the inclination degree as needed to let some falling objects slide down. At the same time, when adjusting the inclination degree, the safety net 201 will be stretched and straightened to a certain extent to adjust the strength of the safety net 201, so as to meet the requirements of different construction buildings. After the slider 204 moves to a suitable position, the pin hole 1012 penetrates through the support frame 101 and is fitted and connected with the slider 204, so that the position of the connecting rod 2 can be stabilized and will not displace by itself.

[0028] The following is the specific implementation process of the present utility model. First, through the connecting piece on one side of the main body 1, it is connected to the side of the construction building. Then, through the connecting rod 2 on the support frame 101, the safety net 201 is connected between the main body 1 and the support frame 101, so as to form an extended protective measure outside the construction building to prevent construction workers or construction materials from falling. At the same time, when a heavy object falls onto the safety net 201, the impact of the heavy object falling will force the safety net 201 to deform and fall downward. When the safety net 201 deforms and sags downward, it will contact the buffer strip 202 to apply pressure. Through the elasticity of the buffer strip 202, it will adapt to the deformation of the safety net 201, and at the same time, it can also slow down the impact when the heavy object falls through the elastic force. When continuously falling and deforming, it will apply pressure to the buffer strip 202 so that both ends of it will be stretched out from the winding roller 2031. The buffer strip 202 is wound around the winding roller 2031 for connection. When pulling the buffer strip 202 to extend, it will drive the winding roller 2031 to rotate. The two ends of the winding roller 2031 are connected by torsion springs. Through the reset of the torsion springs, a certain stretching and reset of the buffer strip 202 will be carried out, so as to further reduce the impact of the heavy object falling and extend the length to adapt to the deformation range. Finally, when setting the safety net 201, the position of the connecting rod 2 on the support frame 101 can be adjusted to make it lift along the support frame 101 through the slider 204 to adjust the inclination angle of the safety net 201, so that the safety net 201 can adjust the inclination degree according to the need to make some falling objects slide down. At the same time, when adjusting the inclination degree, a certain stretching and straightening of the safety net 201 will be carried out to adjust the strength of the safety net 201, so as to adapt to the needs of different construction buildings. After the slider 204 moves to a suitable position, it is connected in an embedded manner through the pin hole 1012 penetrating the support frame 101 and the slider 204, so that the position of the connecting rod 2 can be stabilized and will not displace by itself.

[0029] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
