[0026] One end of the screen net 201 is fixedly mounted on the reel 502, and the other end of the screen net 201 is fixedly mounted in the mounting groove 305 through the avoidance groove at the lower end of the screen box 501, one end of a circulating line 505 is fixedly mounted on the mounting plate 506 at the upper end of the first side frame plate 102, and the other end passes through the wiring groove 302 and is fixedly mounted on the mounting pin 106 at the lower end of the second side frame plate 102; one end of another circulating line 505 is fixedly mounted on the mounting plate 506 at the upper end of the second side frame plate 102, and the other end passes through the wiring groove 302 and is fixedly mounted on the mounting pin 106 at the lower end of the first side frame plate 102.

[0027] The buckle mechanism includes a handle 401, a guide block 402, a limit buckle 2 403 and a spring 404.

[0028] The working principle of the present invention is as follows: the reel mechanism is inserted into the corresponding frame plate 102 through the two mounting plates 506 at both ends, and is detachably mounted on the frame plate 102 through the corresponding connecting plate 105, thereby facilitating the assembly of the reel mechanism and improving the efficiency of assembly through the convenience during assembly.

[0029] When the screen net 201 needs to be opened, the handle 303 is used to pull the pull rod 301 to move, and the pull rod 301 drives the screen net 201 to descend, and the screen net 201 drives the reel 502 to rotate. When the reel 502 rotates, the vortex torsion spring 503 is twisted, and the pull rod 301 drives the limit buckle 1 304 to descend. When the limit buckle 1 304 drops to the position of the limit buckle 2 403, the limit buckle 2 403 is driven to slide on the frame plate 3 103 and the guide block 402 under the action of the inclined surface 1 and the inclined surface 2. At the same time, the spring 404 is compressed. When the limit buckle 1 304 drops to the bottom of the limit buckle 2 403, The limit buckle 2 403 rebounds under the action of the spring 404 and clamps the limit buckle 1 304, thereby limiting the position of the pull rod 301, and then limiting the position of the screen net 201, thereby ensuring the stability of the screen net 201 when it is opened, and at the same time solves the problem in the prior art that the limit buckle needs to be deformed to limit the position, thereby improving the service life. The pull rod 301 and the screen net 201 move through the two set loop lines 505 to ensure the stability of the movement of the screen net 201 and the pull rod 301, and can prevent the screen net 201 and the pull rod 301 from offsetting during movement, resulting in obstruction of movement, thereby improving the smoothness of movement.

[0030] When the screen net 201 needs to be opened, the handle 401 is manually pulled, and the handle 401 drives the limit buckle 2 403 to slide on the guide block 402 and the frame plate 3 103, and the spring 404 is compressed, so that the limit buckle 2 403 moves away from the limit buckle 1 304, and the reel 502 is driven to rotate under the action of the torsional force of the vortex torsion spring 503, and the reel 502 drives the screen net 201 to reel, thereby retracting the screen net 201.
