DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0021] Embodiment: A building window anti-falling net device, as shown in the attached Figure 1 As shown, it includes an anti-falling net 14 and a plurality of transversely arranged window fixing rods 17, the upper and lower edges of the anti-falling net 14 are squeezed and fixed by the ends of the window fixing rods 17, and the side and middle of the anti-falling net 14 are connected to the rod body of the window fixing rod 17 through the tie 15; as shown in the attached Figure 2 As shown, the window fixing rod 17 includes an upper sleeve 1, the inner cavity of the upper sleeve 1 is sleeved with a lower telescopic rod 2 that is movably connected, the upper sleeve and the lower telescopic rod are both made of metal, and the side of the lower telescopic rod 2 is fixed with a rack 3 extending in the length direction of the upper sleeve 1 by bolts; Figure 3 As shown, the lower end of the lower telescopic rod 2 is threadedly matched with a mounting seat 4, as shown in the attached Figure 4 As shown, a pull piece 5 is rotatably connected to the mounting seat 4 via a rotating shaft, and a latch tooth 6 adapted to the rack 3 is integrally formed on the pull piece 5; a locking piece 7 is elastically rotatably connected to the mounting seat 4 on one side of the pull piece 5 via a torsion spring, one end of the torsion spring is connected to the locking piece, and the other end is connected to the mounting seat. After the installation is completed, the locking piece will automatically reset after rotation, and an upwardly arranged bayonet 8 is integrally formed on the locking piece 7, and a block 9 adapted to the bayonet 8 is integrally formed on the side of the pull piece 5. After the bayonet and the block cooperate, the rotation of the pull piece is limited to prevent the latch tooth from leaving the rack; the top end of the upper sleeve 1 and the lower end of the lower telescopic rod 2 are both fixed with anti-skid pads 10 by bolts. The anti-skid pads are made of rubber material and have friction patterns on the surface. When the anti-fall net is squeezed, the friction between the two can be effectively increased, thereby improving the fixing reliability; the anti-skid pads 10 of the lower telescopic rod 2 are inclined , which fits the inclined bottom surface of the building window; the mounting seat 4 is provided with a groove 11 for passing the rack 3, which limits the rack to prevent it from shifting and affecting the engagement of the tooth and the rack; the tooth 6 is arranged at the inner end of the pull member 5, and the tooth can be quickly engaged with the rack; the upper end of the rack 3 is integrally formed with a support block 12 that fits the side of the upper sleeve 1, which improves the support effect on the end of the rack and prevents the rack from bending and affecting the engagement effect; the upper side corners of the outer end of the locking member 7 are processed with an inward push bevel 13, and during the rotation of the pull member, the block can drive the locking member to rotate through the inward push bevel, and then the locking member can be inserted into the bayonet without manually pulling the locking member, thereby improving the convenience of use; the window fixing rod 17 is provided with an indoor fixed point connecting belt 16, which is connected to the indoor fixed point, further improving the fixing reliability and use safety of the window fixing rod.

[0022] Working principle: as attached Figure 1 and attached Figure 5As shown, multiple devices are arranged between the top and bottom surfaces of the building window at a spacing of greater than or equal to 1200mm, and at the same time, the upper edge of the anti-falling net 14 with a mesh density greater than or equal to 500 mesh / 100㎠ is placed on the top of the upper sleeve 1, and the lower edge of the anti-falling net is placed at the lower end of the lower telescopic rod 2, and the upper sleeve 1 and the lower telescopic rod 2 are stretched. When the top of the upper sleeve 1 and the top surface of the building window and the lower end of the lower telescopic rod 2 and the bottom surface of the building window form an extrusion fixation on the anti-falling net, the pull member 5 is rotated to make the clamping tooth 6 embedded in the rack 3 at the current position, and then the locking member 7 is rotated to make the clamping block 9 clamped in the bayonet 8 to fix the pull member 5 to prevent it from rotating, thereby locking the device, and finally, the cable tie 15 is tied on the upper sleeve 1 and the lower telescopic rod 2, and the cable tie 15 is set through the holes of the anti-falling net 14 to fix the middle and both sides of the side of the anti-falling net, and the installation of the anti-falling net is completed. At the same time, an indoor fixed point connecting belt 16 is set at the indoor fixed point to connect with the device to further improve the fixing reliability.
