[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3 This utility model provides an embodiment of a conveniently stored safety net for building construction, comprising left and right connecting rods 1, a winding roller 2 rotatably connected to the inner wall of the left and right connecting rods 1, a safety net body 4 fixedly connected to the outer wall of the winding roller 2, a control rod 5 fixedly connected to the other end of the safety net body 4, a sliding groove 6 opened at one opposite end of each connecting rod 1, the outer wall of the control rod 5 slidably connected to the inner wall of the sliding groove 6, a locking rod 8 slidably connected to the left and right sides of the inner wall of the control rod 5, a locking groove 7 opened at the top and bottom sides of the inner wall of the sliding groove 6, the locking rod 8 and the locking groove 7 being shaped to fit together, a fixing spring 10 fixedly connected to one opposite end of each of the left and right locking rods 8, the other end of each fixing spring 10 fixedly connected to the inner wall of the control rod 5, a moving rod 9 fixedly connected to the bottom end of each locking rod 8 for controlling the movement of the locking rod 8, and spring coils 3 fixedly connected to both sides of the outer wall of the winding roller 2, the other end of each spring coil 3 fixedly connected to the inner wall of the connecting rod 1.

[0023] Specifically, when the safety net body 4 needs to be rolled up, the moving rod 9 on the moving control rod 5 is moved so that the moving rod 9 drives the locking rod 8 into the control rod 5 and compresses the fixing spring 10. At the same time, it disengages from the locking groove 7 inside the slide groove 6, thereby removing the restriction on the control rod 5. This allows the spring coil 3 to drive the winding roller 2 to rotate. Then, the winding roller 2 will roll up the safety net body 4, while simultaneously moving the control rod 5 upward. When the control rod 5 reaches the top, the moving rod 9 is released, and the fixing spring 10 will spring back the locking rod 8 into the locking groove 7 to fix the control rod 5.

[0024] Reference Figure 2 The bottom of the inner wall of the connecting rod 1 is slidably connected with a plug rod 11. The opposite side of the outer wall of the connecting rod 1 is threaded with a bolt 13. The inner wall of the top of the connecting rod 1 is provided with a slot 15. The plug rod 11 fits the shape of the slot 15. The opposite end of the plug rod 11 is fixedly connected with a control block 12. The outer wall of the plug rod 11 is provided with a threaded hole 14. The bolt 13 is detachably connected to the threaded hole 14.

[0025] Specifically, the inner wall of the outer side of the connecting rod 1 is provided with a movable groove, the control block 12 moves within the movable groove, and the insertion rod 11 slides on the inner wall of the connecting rod 1 with a certain frictional force, so that the insertion rod 11 will not easily fall out. The bolt 13 installed on the connecting rod 1 matches the threaded hole 14 opened on the insertion rod 11.

[0026] Working principle: In use, by moving the movable rods 9 on both sides of the control rod 5 towards the center, the movable rods 9 will drive the locking rods 8 to move towards the center. The locking rods 8 compress the fixing springs 10, and at the same time, the locking rods 8 disengage from the locking grooves 7 on the upper side of the slide 6, thus allowing the control rod 5 to move. Then, pulling the control rod 5 will drive the safety net body 4 to move downwards. The safety net body 4 will move downwards from the winding roller 2, thereby driving the winding roller 2 to rotate. The winding roller 2 will stretch the spring coils 3 on both sides. When the control rod 5 moves to the bottom of the slide 6, the movable rods 9 are released. At this time, the fixing springs 10 will rebound the locking rods 8 on both sides, and the locking rods 8 will... Enter the slot 7 at the bottom of the slide 6 to fix the control rod 5, thereby unfolding the safety net body 4. Then, according to the needs of the construction site, multiple safety nets can be spliced ​​together. By moving the control block 12 downward, the control block 12 moves the insert rod 11 out of the connecting rod 1. Remove the bolt 13 on the other connecting rod 1, then insert the insert rod 11 into the slot 15 on the other connecting rod 1, and then screw the bolt 13 back into its original position so that the bolt 13 enters the threaded hole 14 on the insert rod 11, fixing the insert rod 11, thereby connecting the two safety nets together. The connection can be repeated afterward.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
