Description

Technical Field

[0001] This utility model relates to the field of safety warning device technology, and in particular to a safety warning device for building construction. Background Technology

[0002] During construction, warning signs need to be placed around the construction site to remind pedestrians to pay attention to safety. Existing warning signs are mostly one-piece structures that cannot be folded and stored, are relatively bulky, and inconvenient to move and carry. Therefore, there is an urgent need to develop a safety warning device for construction that is simple in structure, easy to operate, easy to store and fold to reduce its size, and easy to move and carry, in order to overcome the shortcomings of current practical applications and meet current needs. Utility Model Content

[0003] The purpose of this invention is to provide a safety warning device for building construction, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A safety warning device for construction includes a lower warning sign, an upper warning sign, a support frame, a limiting mechanism, a rotating shaft, and a clamping nut. The lower end of the upper warning sign is fixed to the rotating shaft, which is rotatably connected to the lower warning sign. Both ends of the rotating shaft have external threads, and a clamping nut is installed on the outer side of each external thread. The support frame is located on the outer side of the lower warning sign, and a support shaft is fixed to it. The support shaft is rotatably connected to the support frame. A limiting mechanism, inserted into the support shaft, is installed on the support frame. The limiting mechanism includes a limiting pin and a spring. The limiting pin is slidably connected to the support frame and inserted into the support shaft. A spring is installed on the outer side of the limiting pin, with one end fixed to the limiting pin and the other end fixed to the support frame. The support shaft has two insertion holes for the limiting pin to pass through.

[0006] Preferably, the included angle between the two sockets is 50°.

[0007] Preferably, a lever is fixed to the outside of the clamping nut.

[0008] Preferably, the lower warning sign has a warning message, and the upper warning sign has a warning symbol.

[0009] The beneficial effects of this utility model are as follows: When using this safety warning device for construction, the lower and upper warning signs are unfolded, and the support frame is rotated to a state where it is tilted relative to the lower warning sign. Then, the lower warning sign and support frame are placed on the ground for support. The warning messages on the lower warning sign and the warning signs on the upper warning sign warn pedestrians. After use, first loosen the clamping nut, then place the upper warning sign onto the lower warning sign, and then tighten the clamping nut to prevent the shaft from rotating. Next, pull the limiting pin out of the insertion hole, then rotate the support frame to a state parallel to the lower warning sign, and then insert the limiting pin back into the insertion hole to fix the support shaft, thereby reducing the size and facilitating movement and carrying. In summary, this utility model has a simple structure, is easy to operate, is easy to store and fold to reduce size, and is convenient to move and carry. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] See Figures 1-6 In this embodiment of the utility model, a safety warning device for construction includes a lower warning sign 1, an upper warning sign 2, a support frame 3, a limiting mechanism 4, a rotating shaft 5, and a clamping nut 6. The lower warning sign 1 is provided with a warning message 102, and the upper warning sign 2 is provided with a warning symbol 201. The lower end of the upper warning sign 2 is fixed to the rotating shaft 5, which is rotatably connected to the lower warning sign 1. Both ends of the rotating shaft 5 are provided with external threads 501. A clamping nut 6 is installed on the outer side of the external threads 501, and a lever 601 is fixed to the outer side of the clamping nut 6. A person rotates the lever 601 by hand to rotate the clamping nut 6. When the clamping nut 6 is tightened and pressed against the outer wall of the lower warning sign 1, the rotating shaft 5 cannot rotate. The support frame 3 is provided on the outer side of the lower warning sign 1. A support shaft 101 is fixed to the outside of the warning sign 1. The support shaft 101 is rotatably connected to the support frame 3. A limiting mechanism 4 is installed on the support frame 3 and inserted into the support shaft 101. The limiting mechanism 4 includes a limiting pin 401 and a spring 402. The limiting pin 401 is slidably connected to the support frame 3 and inserted into the support shaft 101. A spring 402 is installed on the outside of the limiting pin 401. One end of the spring 402 is fixed to the limiting pin 401 and the other end is fixed to the support frame 3. The support shaft 101 is provided with two insertion holes 1011 for the limiting pin 401 to pass through. The included angle between the two insertion holes 1011 is 50°. When the limiting pin 401 is inserted into the insertion hole 1011, the support shaft 101 is blocked and cannot rotate.

[0021] Working principle: This safety warning device for construction work involves unfolding the lower warning sign 1 and the upper warning sign 2, then rotating the support frame 3 to a position where it is tilted relative to the lower warning sign 1. The lower warning sign 1 and the support frame 3 are then placed on the ground for support. The warning text 102 on the lower warning sign 1 and the warning sign 201 on the upper warning sign 2 warn pedestrians. After use, first loosen the clamping nut 6, then attach the upper warning sign 2 to the lower warning sign 1, and then tighten the clamping nut 6 to prevent the rotating shaft 5 from rotating. Next, pull the limiting pin 401 out of the insertion hole 1011. Then, rotate the support frame 3 to a position parallel to the lower warning sign 1, and then insert the limiting pin 401 into the insertion hole 1011 to restrain the support shaft 101, thereby reducing its size and making it easy to move and carry.

[0022] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
