[0027] Compared with the prior art, the utility model provides a warning device for fire protection installation engineering, which has the following beneficial effects:

[0028] The warning device has the advantage of being easy to adjust the area. When the extension column is pulled upward, the limit block connected by the spring on the extension column moves upward. During the movement, the limit block with a bevel on the top is squeezed into the cavity of the extension column and the spring is compressed. When the limit block moves to the limit hole, the elastic force of the spring after compression pushes the limit block into the limit hole. The limit block is fixed. At this time, the extension column raises the height of the warning sign, which is convenient for adapting to the needs of different construction scenes. When the height of the warning sign needs to be lowered for storage and transportation, the staff pushes the limit block into the extension column. When the limit hole does not limit the limit block, the limit block drives the extension column to move downward until it falls into the next limit hole. The limit block is repeatedly pressed. After pressing the limit block multiple times, the extension column drives the warning sign to drop to the lowest point, reducing the space occupied, which is convenient for storage and transportation. The problem that the existing warning device is fixed in size and height, increases the floor space occupied, and is inconvenient for transportation and storage is solved.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Embodiment 1

[0039] See also Figure 1-4A warning device for fire protection installation engineering, comprising a main body component 1, the main body component 1 comprises: a transport seat 11, the bottom of which is symmetrically provided with universal wheels 12; an adjustment component 2 is provided on the transport seat 11, the adjustment component 2 comprises: an adjustment frame 21, which is provided at the top of the transport seat 11; a limit hole 211, which is symmetrically provided on the left side wall of the adjustment frame 21; an extension column 22, which is slidably connected in the adjustment frame 21, and the top of the extension column 22 extends out of the top of the adjustment frame 21; a spring 23, one end of which is fixedly connected to the internal cavity of the extension column 22; a limit block 24, which is fixedly connected to the other end of the spring 23, and the top of the limit block 24 has an inclined surface; a connecting block 25, which is provided at the top of the extension column 22; and a warning sign 26, which is movably connected to the bottom of the connecting block 25. A pull rod 221 is fixedly connected to the front side wall of the extension column 22, and a through slot for the pull rod 221 to move is provided on the adjustment frame 21. A push plate 3 is hinged on the left side of the adjustment frame 21.

[0040] When in use, the staff pushes the transport seat 11, and the universal wheel 12 at the bottom of the transport seat 11 can realize the movement of the device, and the adjustment component 2 can realize the change of the height of the warning sign 26, which is convenient for transportation and storage, and can adapt to the needs of different scenes: the staff pulls up the extension column 22, and the limit block 24 connected to the extension column 22 by the spring 23 moves upward. During the movement, the limit block 24 with a bevel on the top is squeezed into the cavity of the extension column 22, and the spring 23 is compressed. When the limit block 24 moves to the limit hole 211, the elastic force of the spring 23 after compression pushes the limit block 24 in In the limiting hole 211, the limiting block 24 is fixed. At this time, the extension column 22 raises the height of the warning sign 26 to meet the needs of different construction scenes. When the height of the warning sign 26 needs to be lowered for storage and transportation, the staff pushes the limiting block 24 into the extension column 22. When the limiting hole 211 does not limit the limiting block 24, the limiting block 24 drives the extension column 22 to move downward until it falls into the next limiting hole 211. The limiting block 24 is pressed repeatedly. After pressing the limiting block 24 many times, the extension column 22 drives the warning sign 26 to the lowest point, which reduces the space occupied and is convenient for storage and transportation. The staff conveniently realizes the up and down movement of the extension column 22 through the pull rod 221. The pull rod 221 slides in the through groove. The use of the pull rod 221 increases the convenience of the staff to lift the extension column 22. Since it is relatively complicated to press the limit block 24 multiple times to lower the extension column 22, the staff pushes the push plate 3 toward the adjustment frame 21 when lowering the height of the extension column 22, and the protrusions on the push plate 3 extend into the multiple groups of limit holes 211. At this time, the limit holes 211 cannot limit the limit block 24, and the limit block 24 drives the extension column 22 to directly lower to the lowest position, thereby improving the efficiency of lowering the height of the extension column 22.

[0041] Embodiment 2

[0042] On the basis of the first embodiment, an auxiliary function is added.

[0043] See also Figure 1-4 The bottom surface of the adjusting frame 21 is fixedly connected with a spring damper 4, and the top of the spring damper 4 is provided with a bottom plate 5, and the bottom plate 5 is slidably connected to the adjusting frame 21. The outer wall of the push plate 3 is provided with a handle. The connecting block 25 and the warning sign 26 are provided with a connecting mechanism 27, and the connecting mechanism 27 includes: a connecting plate 271, which is fixedly connected to the top of the warning sign 26, and a through groove is provided inside the connecting block 25 for the connecting plate 271 to move; a through hole 272, which is opened on the connecting plate 271; a threaded rod 273, which is threadedly connected to the warning sign 26; a nut 274, which is threadedly connected to the outside of the threaded rod 273.

[0044] When the extension column 22 is lowered, after the bottom end of the extension column 22 contacts the bottom plate 5, the spring shock absorber 4 damps the extension column 22 on the bottom plate 5 to prevent the extension column 22 from being damaged by collision due to the extension column 22 being lowered too quickly. The handle outside the push plate 3 facilitates the staff to operate the push plate 3, which increases the convenience of using the device. The connecting mechanism 27 realizes the connection and separation of the warning sign 26 and the connecting block 25, which is convenient for replacing the warning sign 26 when it is damaged by collision: when the warning sign 26 needs to be replaced, the staff screws the nut 274, the nut disengages from the threaded rod 273, removes the threaded rod 273 from the connecting block 25, moves the connecting plate 271 and the warning sign 26 downward until the connecting plate 271 disengages from the connecting block 25, and the warning sign 26 is disassembled at this time. When installation is required, the connecting plate 271 is extended upward into the through groove at the bottom end of the connecting block 25, the threaded rod 273 is extended into the connecting block 25, and the threaded rod 273 passes through the through hole 272 and extends out of the connecting block 25. At this time, the nut 274 is screwed to the outside of the threaded rod 273 to complete the installation of the warning sign 26.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
