[0026] The "first" and "second" involved in the present utility model do not represent specific quantities and sequences, and are only used for name distinction.

[0027] Combined with the attached Figures 1-4 drawings, an active protection net that is easy to disassemble and assemble in this embodiment includes two mounting seats 1 and a protection net 2. The bottom of the mounting seat 1 is provided with anti-slip load-bearing feet. The mounting seat 1 has a certain weight, mainly playing a role of counterweight to maintain stability. An installation frame 3 is detachably connected to the mounting seat 1. The installation frame 3 is used for the installation of the protection net 2 and is relatively light in weight compared to the mounting seat 1. A winding structure 4 is arranged in the installation frame 3. Both ends of the protection net 2 are respectively connected to the winding structures 4 in the two installation frames 3. The release length of the protection net 2 can be controlled through the winding structure 4.

[0028] When the active protection net that is convenient for disassembly and assembly is in use, the two mounting seats 1 are placed according to the area to be protected on site, and at the same time, positioning work is carried out through the anti-slip load-bearing feet. The mounting frame 3 is embedded inside the mounting seat 1, and the release length of the protection net 2 is controlled by the winding structure 4 to the required protection area, ensuring that the protection net 2 is in a taut state. Since the mounting seat 1 and the mounting frame 3 are detachable structures, they can be separately installed during installation and disassembly. If the mounting seat 1 and the mounting frame 3 are designed as an integral structure, the overall weight will be very heavy, and there will be great construction difficulties during installation and disassembly.

[0029] As a preferred solution of the present utility model, the protection net 2 includes a protection net cloth 21 and a protection net outer frame 22. The material of the protection net outer frame 22 is a rubber material, which has a certain flexibility. Through holes for installing the protection net cloth 21 are provided on the protection net outer frame 22. The protection net outer frame 22 is connected to the winding structure 4. The setting of the protection net outer frame 22 is mainly used to hold the protection net cloth 21 and prevent directly pulling the protection net cloth 21 during winding.

[0030] As a preferred solution of the present utility model, the winding structure 4 includes a rotating shaft 41 and a scroll spring 42. The rotating shaft 41 is rotatably connected to the mounting frame 3. The setting direction of the rotating shaft 41 is along the height direction of the protection net 2. The scroll spring 42 is wound around the rotating shaft 41. The inner end of the scroll spring 42 is fixedly connected to the rotating shaft 41, and the outer end is fixedly connected to the protection net outer frame 22, which is convenient for winding and carrying work.

[0031] As a preferred solution of the present utility model, a plurality of positioning holes 22a are evenly distributed along the length direction of the upper end of the protection net outer frame 22. The upper end of the mounting frame 3 is movably connected up and down with a positioning pin 5. The positioning pin 5 penetrates through the upper end of the mounting frame 3. The upper end of the positioning pin 5 extends out from the upper end of the mounting frame 3 and is connected with an elastic member 6. The elastic member 6 is a spring and is used to push the positioning pin 5 to move downward. After the position of the protection net 2 is adjusted, the positioning pin 5 is inserted downward into the corresponding positioning hole 22a, so as to limit the protection net outer frame 22 in the protection area and prevent the elastic force provided by the scroll spring 42 from retracting. By adjusting the protection area, the applicability is improved.

[0032] As a preferred solution of the present utility model, the mounting bracket 3 is movably connected to the mounting base 1 up and down. When the mounting bracket 3 is installed, it is inserted from the upper end of the mounting base 1, and when it is disassembled, it is pulled out from the upper end of the mounting base 1. A locking structure 7 for fixing the mounting bracket 3 is provided on the mounting base 1. Specifically, the locking structure 7 includes a control shaft 71 rotatably connected to the side surface of the mounting base 1, and the control shaft 71 is perpendicular to the side surface; a screwing part 72 connected to the outer end of the control shaft 71 for manually controlling the rotation of the control shaft 71 by the user; a long locking block 73 connected to the inner end of the control shaft 71, and the two ends of the long locking block 73 are arc-shaped; the control shaft 71 is connected to the middle of the long locking block 73. A chute 3a is provided on the side surface of the mounting bracket 3 along its height direction, the width of the chute 3a is the same as the width of the long locking block 73, and locking grooves 3b are provided on the two side walls of the chute 3a. When the long locking block 73 rotates, its two ends are screwed into the locking grooves 3b. When the mounting bracket 3 is installed, the long locking block 73 rotates to a vertical state to avoid interference with the mounting bracket 3. After the mounting bracket 3 is inserted into the mounting base 1, the long locking block 73 rotates to a horizontal state and its two ends are respectively inserted into the locking grooves 3b on both sides to fix the mounting bracket 3, completing the quick installation work, and at the same time, it is convenient for disassembly and the operation is simple.

[0033] The above has schematically described the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments to this technical solution without creative work without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
