Specific implementation

[0027] The utility model is described in detail below, and the technical scheme in the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model protection.

[0028] The utility model discloses an improved protective frame for house building construction site, and the technical scheme of the utility model is:

[0029] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 9 , a protective frame for house building construction site, first stand 1, second stand 21, third stand 22 and fourth stand 23 are fixedly installed on the ground, the first stand 1, the second stand 21, the third stand 22 and the fourth stand 23 are commonly provided with the protective plate 11, the first stand 1 and the fourth stand 23 are provided with the protective net 10, the second stand 21 and the third stand 22 are also provided with the protective net 10, the four corners of the protective plate 11 and the two ends of the protective net 10 are fixedly installed with the first connecting block 19, the first stand 1, the second stand 21, the third stand 22 and the fourth stand 23 are all fixedly installed with a plurality of second connecting pieces 12, and the first connecting block 19 is fixedly installed with the four stands through the second connecting piece 12, the protective net 10 and the protective plate 11 are firmly fixed on the four stands through the first connecting block 19 and the second connecting piece 12, so that the installation of the protective frame is very simple and convenient.

[0030] AsFigure 3 and Figure 4 As shown, in one embodiment, a first groove 17 is provided in the second connector 12, a second groove 18 is provided in the first groove 17, a fixing block 14 is slidably installed in the second groove 18, a spring 15 is fixedly connected to one end of the fixing block 14, one end of the spring 15 is fixedly connected to the second connector 12, and a first connecting block 19 matches the first groove 17. A third groove 20 is provided on the first connecting block 19, and the third groove 20 matches the fixing block 14. By installing the first connecting block 19 in the first groove 17, the protective plate 11 and the protective net 10 are fixed on the four columns, and the mutual cooperation between the fixing block 14 and the third groove 20 makes the protective plate 11 and the protective net 10 more firmly installed.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, a crossbar 6 is fixedly installed between the first column 1 and the fourth column 23, and a crossbar 6 is also fixedly installed between the second column 21 and the third column 22. A horizontal plate 7 is placed between the two crossbars 6, and the protective plate 11 is located on the horizontal plate 7. The protective plate 11 is made safer by the support of the horizontal plate 7, and the overall stability of the protective frame is ultimately enhanced.

[0032] like Figure 4 As shown, in one embodiment, a push plate 16 is fixedly installed on the fixing block 14. When disassembling the protective frame, the push plate 16 can be manually moved to disengage the fixing block 14 from the third groove 20.

[0033] like Figure 3 As shown, in one embodiment, a cover plate 13 is rotatably mounted on the second connector 12, and the cover plate 13 matches the second groove 18. The cover plate 13 covers the second groove 18 to prevent the fixing block 14 from disengaging from the third groove 20 due to accidental contact during use.

[0034] like Figure 1 , Figure 2 and Figure 7 As shown, in one embodiment, a first connector 3 is fixedly installed between the first column 1 and the fourth column 23, and a first connector 3 is also fixedly installed between the second column 21 and the third column 22. The first connector 3 has a socket 4. A second connecting block 2 is fixedly installed at both ends of the crossbar 6. A pin 5 is movably installed on the second connecting block 2, and the pin 5 matches the socket 4. The second connecting block 2 and the crossbar 6 are fixed to the column by the pin 5.

[0035] like Figure 2 and Figure 6As shown, in one embodiment, a sliding groove 8 is provided on the crossbar 6, and a plurality of mounting grooves 9 are provided on the sliding groove 8. The mounting grooves 9 match the cross plate 7, and the cross plate 7 is placed in the mounting grooves 9 through the sliding groove 8, thereby supporting the protective plate 11 on the cross plate 7.

[0036] The specific working method is as follows: When installing the protective frame, firstly, four columns are fixedly installed on the ground, and then the first connector 3 and the second connector 12 are fixedly installed on the four columns. Then, through the cooperation of the pin 5 and the socket 4, the second connector 2 and the crossbar 6 are fixedly installed between the first column 1 and the fourth column 23. The crossbar 6 is also installed between the second column 21 and the third column 22. The crossbar 7 slides into the installation groove 9 through the slide groove 8, thereby completing the installation of the protective frame.

[0037] When installing the protective net 10 and the protective plate 11, firstly insert the first connecting blocks 19 at both ends of the protective net 10 and the four corners of the protective plate 11 into the first groove 17. The first connecting blocks 19 press the fixing blocks 14, and the fixing blocks 14 slide into the second groove 18. The spring 15 is compressed. When the first connecting blocks 19 are fully inserted into the first groove 17, the fixing blocks 14 are inserted into the third groove 20 under the elastic force of the spring 15, thereby firmly fixing the protective plate 11 and the protective net 10 to the four pillars.

[0038] When dismantling the protective frame after construction is completed, open the cover plate 13, move the push plate 16, and the push plate 16 will cause the fixing block 14 to disengage from the third groove 20 on the first connecting block 19, thereby removing the protective plate 11 and the protective net 10 from the four columns. Then, pull the pin 5 out of the socket 4 to disengage the crossbar 6 from the four columns. Then, remove the crossbar 7 along the slide groove 8. Finally, remove the four columns from the ground. In this way, the protective frame can be quickly installed and dismantled, greatly reducing labor intensity.

[0039] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
