[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] A typical embodiment of this utility model is as follows: Figure 1 As shown, a work warning sign includes two uprights 1 arranged symmetrically. The top and bottom of the two uprights 1 are connected by a crossbeam 2, forming a rectangular structure. A warning light 3 is fixed to the middle of the upper surface of the crossbeam 2 at the top of the two uprights 1. Two connecting rods 4 are also connected between the two crossbeams 2, with a set distance between them. An indicator sign 5 is fixed between the two connecting rods 4, and the indicator sign 5 is marked with a warning symbol. In this embodiment, the indicator sign 5 is marked with "Work in Progress" to remind non-work personnel not to approach.

[0021] Both uprights 1 are connected to support rods 6 at their bottom ends. The two support rods 6 are set in parallel and perpendicular to each other. The bottom end of the upright is fixedly connected to the middle of the upper surface of the support rod 6. One of the support rods 6 has fixed legs 7 fixedly connected to both ends of its bottom surface, and the other upright has casters 8 rotatably connected to both ends of its bottom surface. The casters 8 facilitate the movement of the warning sign. The casters 8 are locking casters, which can be locked when the warning sign is placed to ensure the stability of the warning sign.

[0022] Furthermore, the bottom end of the upright 1 is connected to the support rod 6 via a rotating mechanism, as shown below. Figure 2 As shown, the rotating mechanism includes a rotating base 9 and a rotating shaft 10. The rotating base 9 is adapted to the upright 1 and is sleeved on the bottom end of the upright 1. The bottom end of the rotating shaft 10 is fixed to the middle of the upper surface of the support rod 6 by bolts. Figure 3 As shown, a shaft hole 901 is provided at the axis of the rotary seat 9. The shaft hole 901 is adapted to the rotating shaft 10. The top end of the rotating shaft 10 can be inserted into the shaft hole 901, thereby realizing the rotational connection between the rotary seat 9 and the rotating shaft 10.

[0023] Multiple bolt holes 902 are provided on the side wall of the rotating base 9. The bolt holes 902 are perpendicular to the rotating shaft 10 and pass through the rotating base 9. In this embodiment, there are four bolt holes 902, two of which are symmetrically opened on the upper part of the rotating base 9 and the other two are symmetrically opened on the bottom of the rotating base 9. Multiple first through holes are provided on the side walls on both sides of the bottom end of the upright 1. The multiple first through holes are corresponding to the multiple bolt holes 902. By inserting bolts into the first through holes and bolt holes 902 and tightening them with nuts, the fixed connection between the upright 1 and the rotating base 9 is achieved.

[0024] like Figure 4 As shown, a plurality of annular grooves 1001 are provided on the outer circular surface of the rotating shaft 10. The plurality of annular grooves 1001 are correspondingly provided with a plurality of bolt holes 902. In this embodiment, there are two annular grooves 1001. The two annular grooves 1001 are arranged side by side along the axis of the rotating shaft 10. When the rotating shaft 10 is inserted into the shaft hole 901, the upper annular groove 1001 is located between the two bolt holes 902 on the upper part of the rotating base 9, and the lower annular groove 1001 is located between the two bolt holes 902 on the lower part of the rotating base 9.

[0025] The middle part of the bolt hole 902 is connected to the shaft hole 901. When the bolt is inserted, half of the bolt located in the middle of the bolt hole 902 is located in the bolt hole 902, and the other half is located in the annular groove 1001. Thus, the bolt is used to achieve a fixed connection between the rotating seat 9 and the rotating shaft 10 without affecting the rotation of the rotating shaft 10.

[0026] Limiting holes 903 are also provided on the side walls of both sides of the rotating base 9. The two limiting holes 903 are correspondingly arranged and are connected to the shaft hole 901. Multiple limiting grooves 1002 are provided on the outer circular surface of the rotating shaft 10. In this embodiment, there are four limiting grooves 1002. The four limiting grooves 1002 are symmetrically arranged on the outer circular surface of the rotating shaft 10, and the four limiting grooves 1002 are correspondingly arranged with the limiting holes 903. That is, when the rotating shaft 10 rotates 90 degrees, there are always two limiting grooves 1002 corresponding to two limiting holes 903 respectively.

[0027] A second through hole is also provided on the two side walls at the bottom end of the upright 1. The two second through holes are respectively set to correspond to the two limiting holes 903. A limiting mechanism 11 is fixed on the two side walls at the bottom end of the upright 1. The two limiting mechanisms 11 are respectively fixed to the outside of the two second through holes. The limiting mechanism 11 includes a housing 1101. The housing 1101 is fixed on the two side walls at the bottom end of the upright 1. A top rod hole is provided on the side of the housing 1101 near the side wall of the upright 1. The top rod hole is set to correspond to the second through hole. A top rod 1102 is slidably connected in the top rod hole. A spring 1103 is provided between the top rod 1102 and the bottom surface of the top rod hole. The spring 1103 provides the thrust. It can be seen that a limit is provided between the top rod hole and the top rod 1102 to prevent the top rod 1102 from sliding out of the top rod hole.

[0028] The end of the push rod 1102 away from the spring 1103 passes through the second through hole and the limiting hole 903 in sequence, and contacts the bottom surface of the limiting groove 1002. Both the end of the push rod 1102 and the bottom surface of the limiting groove 1002 are arc-shaped surfaces, and the two are compatible. Whenever the rotating shaft 10 rotates 90 degrees, the ends of the push rods 1102 of the limiting mechanisms 11 on both sides can contact the bottom surface of the limiting groove 1002, and the rotation of the rotating shaft 10 is limited by the push rod 1102 and the limiting groove 1002.

[0029] Multiple fixing holes 1003 are provided on the top outer circular surface of the rotating shaft 10. There are four fixing holes 1003, which are symmetrically arranged and all located above the limiting groove 1002. A threaded hole is also provided on one side wall of the upright 1. The fixing holes 1003 are correspondingly arranged with the threaded holes. A fixing bolt is threaded into the threaded hole. The fixing bolt is a common hand-tightening bolt. When the rotating shaft 10 is rotated to the position, the fixing bolt is tightened so that the end of the fixing bolt is inserted into the fixing hole 1003, thereby fixing the rotating shaft 10 and preventing the rotating shaft 10 from rotating.

[0030] By setting a rotating mechanism between the upright 1 and the support rod 6, when storing the warning sign, the support rod 6 can be rotated through the rotating mechanism to make the support rod 6 parallel to the crossbeam 2, thereby reducing the footprint of the warning sign and making it easier to store.

[0031] It also includes support mechanisms 12, of which there are two, each detachably connected to both sides of the upright 1, such as... Figure 5 As shown, the support mechanism 12 includes a strut 1201 and a support arm 1202. One end of the support arm 1202 is hinged to the side wall of the strut 1201. Multiple screw holes 101 are provided on the outer side of the upright 1. The multiple screw holes 101 are arranged side by side along the length of the upright 1, and there is a set distance between two adjacent screw holes 101. The top of the strut 1201 is provided with a mounting hole. A locking bolt 1203 is threaded through the mounting hole and connected to the screw hole 101, thereby realizing the fixed connection between the strut 1201 and the upright 1. The strut 1201 can tilt behind the warning sign to support the warning sign. By fixing the top of the strut 1201 in different screw holes 101 with the locking bolt 1203, the tilt angle of the strut 1201 can be adjusted, so that the warning sign can be stably supported even if the ground is uneven.

[0032] A U-shaped groove 1204 is provided at the end of the support arm 1202 away from the support rod 1201. The locking bolt 1203 passes through the U-shaped groove 1204 and is threadedly connected to the screw hole 101, thereby realizing the fixed connection between the support arm 1202 and the upright 1. By setting the support arm 1202, the support rod 1201 can be supported, which improves the reliability of the support mechanism 12. By setting the U-shaped groove 1204 at the end of the support arm 1202, the fixed position of the support arm 1202 can be adjusted to adapt to different tilt angles of the support rod 1201.

[0033] By installing support mechanisms 12 at both ends of the pole 1, the warning sign can be supported by the support mechanisms 12 when it is placed by the sea, thus preventing the warning sign from being blown over by the sea breeze.

[0034] The locking bolt 1203 is a common hand-tightening bolt on the market. When the support is not needed, the operator can manually unscrew the locking bolt 1203 to remove the support mechanism 12.

[0035] Two clamps 401 are fixed to the bottom rear side of each of the two connecting rods 4. The clamps 401 are C-shaped with an opening on one side. The clamps 401 on the two connecting rods 4 are symmetrically arranged. The clamps 401 are adapted to the support rod 1201, such as... Figure 7 As shown, when the support rod 1201 is not needed, the support rod 1201 can be locked onto the clamp 401 from the opening, which makes it convenient to place the support rod 1201 and prevents the support rod 1201 from being lost.

[0036] Furthermore, it also includes a counterweight 13, which can be placed on the support rod 6 to increase the weight of the warning frame and prevent it from being blown away by strong winds. Specifically, such as... Figure 6As shown, a handle 1301 is provided on the top of the counterweight 13 to facilitate the handling of the counterweight 13 by the staff. A fixing groove 1302 is provided on the bottom surface of the counterweight 13. The fixing groove 1302 is adapted to the support rod 6, so that the support rod 6 can be placed in the fixing groove 1302 to ensure the stability of the counterweight 13 when it is placed. A positioning hole 1303 is provided on the top surface of the fixing groove 1302. A fixing rod 601 is fixed on the support rod 6. The bottom end of the fixing rod 601 is fixedly connected to the upper surface of the support rod 6 by bolts. The fixing rod 601 is adapted to the positioning hole 1303. When the counterweight 13 is placed on the support rod 6, the fixing rod 601 can be inserted into the positioning hole 1303 to prevent the counterweight 13 from moving and further ensure the stability of the counterweight 13.

[0037] This utility model connects the upright and the support rod through a rotating mechanism. When storing the warning sign, the support rod can be rotated through the rotating mechanism to make the support rod parallel to the board surface, thereby reducing the floor space occupied by the warning sign and making it easier to store.

[0038] Meanwhile, by installing support mechanisms on both sides of the pole, the warning sign can be effectively supported when placed by the sea, preventing it from being blown over by the sea breeze.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
