DETAILED DESCRIPTION

[0030] 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.

[0031] Example 1

[0032] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0033] A warning device for building construction, comprising:

[0034] Shell 1;

[0035] A slider 8, the slider 8 is slidably connected in the housing 1;

[0036] A rack 9, the rack 9 is fixedly connected to the lower end of the slider 8;

[0037] A warning sign 4, which is fixedly connected to the upper end of the slider 8;

[0038] A base 2, the base 2 is fixedly connected to the lower end of the housing 1;

[0039] A circular hole 11 is provided at one side end of the housing 1;

[0040] A hollow groove 12, which is formed on the inner circumferential wall of the circular hole 11;

[0041] Two sets of locking mechanisms, each set of locking mechanisms includes a tooth plate 10, a connecting rod 13, a limit block 14, a hollow rod 15, a spring 16 and a slide groove 17. The tooth plate 10 is located in the shell 1, and the spring 16 is fixedly connected to the inner wall of one side of the shell 1 and the close end of the tooth plate 10. The hollow rod 15 is fixedly connected to one side end of the tooth plate 10. The hollow rod 15 is slidably connected in the circular hole 11. The slide groove 17 is opened on the circumferential inner wall of the hollow rod 15. The connecting rod 13 is located in the hollow rod 15. The limit block 14 is fixedly connected to the circumferential surface of the connecting rod 13. The limit block 14 is located in the slide groove 17, and the tooth plate 10 is meshed with the rack 9.

[0042] In a specific embodiment of the present invention, the surface of the warning sign 4 can be used to paste some warning slogans. When used at night, in order to prevent the device from being touched by vehicles, personnel can twist the connecting rod 13 to make the limit block 14 enter the hollow groove 12, so that the hollow rod 15 can be pulled outward, and the hollow rod 15 slides in the circular hole 11, and the tooth plate 10 will be separated from the rack 9. After the elastic force of the spring 16 is squeezed, the connecting rod 13 continues to rotate to make the limit block 14 fit the outer side of the shell 1, so that the rack 9 and the tooth plate 10 can be temporarily separated, and personnel can put the warning sign 4 on the outer side of the shell 1. The warning sign 4 is pulled upward, and the slider 8 and the rack 9 can slide upward in the housing 1. After reaching a certain distance, the bottom half of the rack 9 is suspended in the air, and the connecting rod 13 is twisted in the opposite direction to restore the hollow rod 15. The pressure of the spring 16 is released, so that the tooth plate 10 continues to mesh with the semi-suspended rack 9 to limit the slider 8. Under the action of the housing 1, the slider 8 will not shake, and the connecting rod 13 can be limited by the slide groove 17 to prevent it from falling. In this way, the height of the warning sign 4 can be raised, which is convenient for use at night, saves energy, and improves the use effect.

[0043] For details, please refer to Figure 2 Both side ends of the warning sign 4 are adhesively connected with reflective strips 7, and the thickness of the reflective strips 7 is 1 cm.

[0044] In this embodiment, the reflective strips 7 pasted on both sides can help people see the warning sign 4 at night and play a warning role. The thickness of the reflective strips 7 is 1 cm, which is convenient for use and makes the device more stable and firm, and not easy to be damaged.

[0045] For details, please refer to Figure 1-Figure 2 Two reflectors 5 are fixedly connected to the upper end of the warning sign 4, and the two reflectors 5 are designed in opposite directions.

[0046] In this embodiment, the reflector 5 can be used to warn people at night. The two reflectors 5 are designed in opposite directions, which can be used by left and right vehicles to improve safety.

[0047] For details, please refer to Figure 1-Figure 2 A protective cover 6 is sleeved on the surface of the slider 8, and the material of the protective cover 6 is stainless steel.

[0048] In this embodiment: if it rains, the protective cover 6 can be used to prevent water from entering the housing 1, thereby protecting the safety of the equipment in the housing 1. At the same time, the material of the protective cover 6 is stainless steel, which has a certain anti-corrosion effect, so that the device will not be corroded during long-term use.

[0049] For details, please refer to Figure 1 The lower end of the base 2 is fixedly connected with a universal wheel 3.

[0050] In this embodiment: the device has four sets of universal wheels 3, which can make the device easy to move. At the same time, a brake device is provided inside the universal wheels 3 to facilitate the universal wheels 3 to stop running at any time.

[0051] For details, please refer to Figure 1-Figure 2 , the slider 8 matches the housing 1.

[0052] In this embodiment, the shape of the slider 8 matches the inner wall of the housing 1 , and the slider 8 does not shake during the rising process and when it stops, thereby achieving a stable effect.

[0053] The working principle and use process of the utility model are as follows: when it needs to be raised or lowered during nighttime use, the connecting rod 13 is twisted so that the limit block 14 enters the hollow groove 12 and pulls the hollow rod 15 outward. After the elastic force of the spring 16 is squeezed, the connecting rod 13 continues to rotate so that the limit block 14 fits against the outer side of the shell 1. After the rack 9 and the toothed plate 10 are temporarily separated, the warning sign 4 is pulled upward so that the bottom half of the rack 9 is suspended in the air. Then, the connecting rod 13 is twisted in the opposite direction to restore the device, so that the toothed plate 10 continues to mesh with the half-suspended rack 9, and the slider 8 is limited. In this way, the height of the warning sign 4 can be raised, which is convenient for use at night, saves energy, and improves the use effect.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
