DETAILED DESCRIPTION

[0022] In order to further understand the content of the present application, the present application will be described in detail in conjunction with the drawings and examples. It should be understood that the examples are merely an explanation of the present application and not a limitation.

[0023] The following will be described in detail in conjunction with the drawings and examples. Figures 1-5 The present embodiment will be further described in detail.

[0024] Please refer to Figures 1-5 The quick-splicing warning fence for building safety protection in the present embodiment comprises a stand 100 and a main fence frame 101. The four corners of the main fence frame 101 are provided with front connecting blocks 102. The stand 100 is internally provided with a cavity 103 with an upper opening. The cavity 103 is internally provided with sliding blocks 104 which are symmetrical in upper and lower directions and are slidable. The two sides of the stand 100 are respectively provided with vertical cavities 105 which are in communication with the cavity 103. The two sides of the sliding blocks 104 are respectively provided with rear connecting blocks 106 which extend from the vertical cavities 105. The front connecting blocks 102 and the rear connecting blocks 106 are respectively provided with lock holes 107. The stand 100 is provided with a limiting assembly for limiting the sliding blocks 104. The top end of the stand 100 is provided with an auxiliary fence frame 108 which is splicable. The top end of the stand 100 is provided with a connecting assembly for connecting the auxiliary fence frame 108.

[0025] In the present embodiment, the front connecting blocks 102 are fixedly connected with the main fence frame 101, and the rear connecting blocks 106 are fixedly connected with the sliding blocks 104. When the main fence frame 101 is installed, the lock holes 107 on the front connecting blocks 102 and the rear connecting blocks 106 on one side are aligned, and are fixed by bolts. Then, the lock holes 107 on the front connecting blocks 102 and the rear connecting blocks 106 on the other side are aligned, and are fixed by bolts.

[0026] In this embodiment, when a height difference exists between adjacent posts 100 causing the lock holes 107 to misalign, the limiting component releases the limiting of the slider 104, allowing the slider 104 to slide up and down within the cavity 103. This causes the rear connecting block 106 to slide up and down until the lock hole 107 on the rear connecting block 106 aligns with the lock hole 107 on the front connecting block 102. The limiting component then limits the slider 104 to prevent it from sliding, and finally, it is fixed with bolts. This solves the problem that when uneven ground or installation errors cause inconsistent heights of the posts 100, the lock holes 107 of the fence frame and the posts 100 may not align, requiring on-site adjustments, such as re-drilling or raising, which is time-consuming and affects structural strength.

[0027] In this embodiment, the warning fence can be heightened according to usage requirements. When the warning fence is heightened, a secondary fence frame 108 can be installed at the top of the column 100 through the connecting component to increase the overall height of the warning fence frame, thereby improving the overall applicability and versatility of the device.

[0028] Please see Figures 1-5 In this embodiment, the column 100 does not have a vertical cavity 105. On both sides, there are limiting holes 200 that communicate with the cavity 103. The limiting holes 200 are set for the slider 104. The limiting component includes a first threaded rod 201 that passes through the limiting hole 200 and connects to the slider 104. A limiting nut 202 is provided on the first threaded rod 201.

[0029] In this embodiment, when it is necessary to adjust the position of the lock hole 107 to align the lock hole 107, the limiting nut 202 can be tightened to release the limiting of the slider 104, allowing the slider 104 to slide within the cavity 103, which in turn drives the rear connecting block 106 to slide up and down to align the lock hole 107. Once the lock hole 107 is aligned, the limiting nut 202 can be tightened to limit the slider 104. Anti-slip pads can be fitted on the first screw between the limiting nut 202 and the side of the column 100 to increase friction and better limit the slider 104.

[0030] Please see Figures 1-5 In this embodiment, the connecting assembly includes a lifting block 300 located at the top of the column 100. The lifting block 300 has a groove 301 with an open bottom. The lifting block 300 is slidably fitted onto the column 100 via the groove 301. The lifting block 300 has a clamping groove 302. Inserts 303, which can be inserted into the clamping groove 302, are located at the bottom of both sides of the secondary fence frame 108. Clamping pieces 304, which can move away from or closer to each other, are located within the clamping groove 302. A second threaded rod 305, which extends into the clamping groove 302 and is threadedly connected to the clamping piece 304, is located on the lifting block 300.

[0031] In this embodiment, the insert 303 is fixedly connected to the sub-fence frame 108. When the sub-fence frame 108 is installed, the insert 303 can be inserted into the clamping groove 302 and positioned between the clamping pieces 304. Then, the second threaded rod 305 is rotated to bring the clamping pieces 304 closer together to clamp the insert 303.

[0032] In this embodiment, the second threaded rod 305 is mounted on the lifting block 300 via a bearing. The second threaded rod 305 is provided with a bidirectional thread so that the clamping pieces 304 can move closer or further apart from each other.

[0033] Please see Figures 1-5 In this embodiment, the bottom wall of the groove 301 is provided with a rod 306 connected to the slider 104.

[0034] In this embodiment, the rod 306 is fixedly connected to the bottom wall of the groove 301 and the slider 104. When there is a height difference between the columns 100, during the process of adjusting the alignment of the lock hole 107, the lifting block 300 can be simultaneously adjusted by the connection of the rod 306, thereby avoiding the tilting of the installation of the sub-fence frame 108 due to the height difference between the columns 100.

[0035] Please see Figures 1-5 In this embodiment, the bottom end of the column 100 is provided with a base 109 for fixing the column 100.

[0036] In this embodiment, the base 109 is fixedly connected to the bottom end of the column 100. Pre-drilled holes can be made at the four corners of the base 109 so that the base 109 can be fixed by expansion bolts to complete the installation of the column 100.

[0037] Please see Figures 1-5 In this embodiment, baffles 110 are evenly spaced inside the main fence frame 101 and the secondary fence frame 108, and a warning sign 111 connected to the baffles 110 is provided inside the main fence frame 101.

[0038] In this embodiment, the barrier strip 110 is fixedly connected to the main fence frame 101 and the secondary fence frame 108 respectively, and the warning sign 111 is fixedly connected to the barrier strip 110. Reflective warning words can be sprayed or pasted on the warning sign 111 according to the usage requirements, and reflective strips can be pasted on the lower side of the main fence frame 101.

[0039] When the lock hole 107 needs to be adjusted for alignment during use, the limiting nut 202 can be loosened to allow the slider 104 to slide up and down in the cavity 103, which will drive the rear connecting block 106 to slide up and down until the lock hole 107 on the front connecting block 102 and the rear connecting block 106 are aligned. Then the limiting nut 202 can be tightened.

[0040] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
