As shown in fig. 1, the protective net assembly 60 has a protective net body 61 and four assembling portions 62 disposed at the corner ends of the protective net body 61, and the protective net body 61 is assembled with the four connecting bases 17 of the connecting assembly 104 through the assembling portions 62 to form a second stage of protection of the device of the present invention, so as to catch the high-altitude falling body that rolls toward the mounting base 10 because the free end of the supporting rail 30 is higher than the hinged end.
In the embodiment of the present invention, the number and the arrangement positions of the assembling portions 62 of the protective net assembly 60 may be arranged according to the shape of the protective net body 61, the assembling portions 62 are also arranged at the edge of the protective net body 61, and the connecting bases 17 corresponding to the number and the positions of the assembling portions 62 may be arranged between the supporting rod frames 101 of the mounting base 10, so as to achieve a good arresting effect.
The concrete structure of the fall preventing device for building construction of the present invention is explained above, and the operation principle of the device of the present invention is explained below.
When a falling body (a person or a member) falls on the surface of the net body 51 of the net bearing assembly 50, at the moment, the pressed position of the net body 51 is deformed downwards, meanwhile, the first guide block 33 on the side surface (or the first guide block 33 and the second guide block 35) moves close to the falling body, the net body 51 forms a coating shape on the falling body, and meanwhile, the transverse spring 26 and the vertical spring 12 are extruded and deformed, so that the downward impact of the net body 51 can be buffered.
When the supporting cross bar 30 needs to be folded, the bolt 15 is directly controlled to withdraw from the connecting sleeve 14, after the body 151 of the bolt 15 is separated from the connecting sleeve 14, the whole buffering slide seat 20 can be controlled to move upwards to the placing opening 112, and the slide block 23 is pulled out of and withdrawn from the sliding groove 11, so that the whole buffering slide seat 20 is taken down. The support rail 30 is then controlled to rotate upwardly.
Before the support cross bar 30 rotates, the first guide block 33 close to the end of the support cross bar 30 is controlled to be aligned with the insertion hole 321 of the guide groove 32, and when the insertion groove 331 corresponds to the insertion hole 321, the positioning pin 38 is directly inserted into the insertion groove 331 and the insertion hole 321, so that the net body 51 can be fixed at a specific position of the support cross bar 30, and the net body 51 is prevented from rolling down and folding when the support cross bar 30 rotates and erects.
While the present invention has been described in detail and with reference to the accompanying drawings and examples, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Accordingly, certain details of the embodiments are not to be interpreted as limiting, and the scope of the invention is to be determined by the appended claims.
