[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-4 The utility model provides a technical solution: a high-altitude anti-fall net at a construction site, comprising an L-shaped bracket 1 and a net body 6. A hinge ear 103 is fixedly connected to the upper portion of the L-shaped bracket 1 near the rear end edge, and a hinge head 202 is rotatably connected to the hinge ear 103. A lower support plate 2 is fixedly connected to the front of the hinge head 202. A mounting groove 3 is provided on the lower support plate 2. The net body 6 is placed in the mounting groove 3. A downward clamping plate 4 is slidably installed in the mounting groove 3, and a plurality of convex thorns 404 are fixedly connected to the lower portion of the downward clamping plate 4.
[0021] In this embodiment, by pressing down the clamping plate 4 to clamp the mesh 6, the thorns 404 will be inserted into the gaps between the mesh 6, thereby fixing the mesh 6 inside the mounting groove 3, and the L-shaped bracket 1 is fixed to the outer wall of the building. Figure 1 As shown, the mesh body 6 can be fixed on the outer wall of the building, and the lower supporting plate 2 cooperates with the hinge head 202 through the hinge ear 103 and is rotatably installed on the L-shaped bracket 1. Under normal conditions, the lower supporting plate 2 will be placed on the L-shaped bracket 1 due to gravity. When the mesh body 6 needs to be replaced and repaired later, the mesh body 6 can be pulled at the window position of the building to drive the lower supporting plate 2 to rotate, so that the lower supporting plate 2 is in a vertical state and fits the window position of the building. Then, when the operator is in the window, he can slightly lean out of the body to remove the downward clamping plate 4 to complete the inspection or replacement of the mesh body 6.
[0022] Among them, in order to achieve the purpose of improving the bearing capacity of the device, the present device is implemented by adopting the following technical solutions: a fixing hole 101 is opened in the L-shaped bracket 1, a plug-in groove 102 is opened on the L-shaped bracket 1, a plug-in strip 201 is fixedly connected to the bottom of the lower support plate 2, the plug-in strip 201 and the plug-in groove 102 cooperate with each other, a rope hook 203 is fixedly connected to the top of the lower support plate 2 near the front end edge, and a diagonal rope 5 is fixedly connected to the rope hook 203.
[0023] The L-shaped bracket 1 can be fixed to the outer wall of the building through the fixing hole 101 with the bolt. The plug-in slot 102 and the plug-in strip 201 are interference fit. The plug-in strip 201 needs to be pressed down hard to be inserted into the plug-in slot 102, thereby preventing the lower support plate 2 from rotating at will. A certain amount of manual force needs to be applied to realize the rotation of the lower support plate 2. At the same time, when the net body 6 blocks the falling objects, the force applied will apply lateral tension to the lower support plate 2. The plug-in strip 201 is inserted into the plug-in slot 102, which can transmit the lateral tension to the L-shaped bracket 1, preventing the hinged ear 103 from bearing all the lateral tension. One end of the inclined rope 5 is wrapped around the rope hook 203, and the other end is fixed to the outer wall with a pin. Figure 1 As shown, a certain pulling force can be provided for the lower supporting plate 2 to improve the bearing capacity of the device.
[0024] Among them, in order to achieve the purpose of fixing the downward clamping plate 4 in the installation groove 3, this device adopts the following technical solutions: an avoidance groove 301 is opened at the bottom of the installation groove 3, the avoidance groove 301 cooperates with the ridge 404, and threaded fixing holes 302 are opened in the installation groove 3 and located in front and behind the avoidance groove 301. The front and rear ends of the downward clamping plate 4 are fixedly connected to the fixing seat 401, and a through hole 402 is opened in the fixing seat 401. A fixing bolt 403 is provided in the through hole 402, and the fixing bolt 403 is threadedly cooperated with the threaded fixing hole 302.
[0025] By cooperating with the avoidance groove 301 and the ridge 404, interference between the ridge 404 and the lower support plate 2 is avoided, so that the downward clamping plate 4 cannot be installed in the installation groove 3. The fixing bolt 403 is threadedly engaged with the threaded fixing hole 302. The fixing bolt 403 is passed through the through hole 402 and screwed into the threaded fixing hole 302 to fix the downward clamping plate 4 inside the installation groove 3.
[0026] When the fixing bolts 403 are screwed into the through holes 402, the clamping plate 4 can be fixed to the inside of the mounting groove 3. At this time, the clamping plate 4 can be fixed to the mounting groove 3. One end of the inclined rope 5 is wound around the rope hook 203, and the other end is fixed to the outer wall with a pin to keep the inclined rope 5 in a tensioned state. When the net body 6 needs to be repaired and replaced later, it is only necessary to pull the net body 6 to drive the lower supporting plate 2 to rotate, so that the lower supporting plate 2 and the net body 6 are in a vertical state, so that the pressing clamping plate 4 fits the window position of the building, and unscrew the fixing bolts 403 to release the fixation of the pressing clamping plate 4. At this time, the net body 6 can be easily removed for repair and replacement.
[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
