An insertion rod is slidably installed in the middle of the upper part of the horizontal plate. A support ring is fixedly sleeved on the outer side of the insertion rod. A warning sign is fixed to the upper end of the adjusting shaft. A zero-gravity wind cap is symmetrically rotatably installed above the warning sign. The surfaces of the two zero-gravity wind caps are provided with a reflective coating.

[0006] Furthermore, a first pull plate is fixed to the left end of the positioning rod, a second spring is fixed to the right side of the first pull plate, and the right end of the second spring is fixed to the U-shaped plate. The U-shaped plate is fixed to the front side of the second cylinder, and a second transition hole is provided on the front side of the second cylinder.

[0007] Furthermore, a first spring is fixed above the support ring, the upper end of the first spring is fixed to the cross plate, and a second pull plate is installed on the upper end of the insertion rod.

[0008] Furthermore, the diameter of the insertion rod is smaller than the diameter of the locking hole, and the diameter of the locking hole is equal to the diameter of the unlocking hole.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-7 This utility model provides a technical solution: a mine safety early warning device, including a first cylinder 1, a U-shaped plate 9, and an adjusting rod 15. The upper front end of the first cylinder 1 has a first transition hole 11. A second cylinder 5 is fixed to the upper end of the adjusting rod 15. A ring 13 is fixed to the inner wall of the second cylinder 5. An adjusting shaft 7 is rotatably mounted on the inner ring of the ring 13. A disc 16 is fixed to the lower end of the adjusting shaft 7. Multiple insertion holes 17 are provided on the annular side of the disc 16. A positioning rod 20 is slidably installed on the left side of the U-shaped plate 9. A locking hole 26 and an unlocking hole 21 are sequentially provided above the positioning rod 20 from left to right. The interior of the U-shaped plate 9... A horizontal plate 22 is fixed at the top, and a rod 25 is slidably installed in the middle of the upper part of the horizontal plate 22. A support ring 23 is fixedly sleeved on the outside of the rod 25. A warning sign 3 is fixed at the upper end of the adjusting shaft 7. A zero-gravity wind cap 4 is symmetrically rotated and installed above the warning sign 3. The surfaces of the two zero-gravity wind caps 4 are coated with reflective coating. This design solves the problems of the original device being easily perched on by birds, and bird droppings contaminating and obscuring the warning sign and corroding the structure, thus affecting the warning effect. Secondly, the angle adjustment of the warning sign requires the cooperation of both hands. It is necessary to continuously apply force to keep it unlocked in order to rotate and adjust, which is extremely inconvenient for single-person operation and cannot meet the needs of rapid deployment.

[0016] In the first embodiment of this utility model: a first pull plate 18 is fixed to the left end of the positioning rod 20, and a second spring 19 is fixed to the right side of the first pull plate 18. The right end of the second spring 19 is fixed to the U-shaped plate 9, and the U-shaped plate 9 is fixed to the front side of the second cylinder 5. A second transition hole 12 is provided on the front side of the second cylinder 5. The second spring 19 provides the positioning rod 20 with an automatic reset force to ensure that it is not easily displaced under normal conditions. The first pull plate 18 is easy to operate manually. The second transition hole 12 provides space for the movement of the positioning rod 20. A first spring 6 is fixed above the support ring 23. The upper end of the first spring 6 is fixed to the horizontal plate 22. A second pull plate 24 is installed on the upper end of the insertion rod 25. The first spring 6 provides downward pressure to ensure that the insertion rod 25 remains in contact with the positioning rod 20 without human intervention. The second pull plate 24 facilitates the upward lifting of the insertion rod 25 when it is necessary to fully unlock. The support ring 23 serves as the force support for the first spring 6. The diameter of the insertion rod 25 is smaller than the diameter of the locking hole 26, and the diameter of the locking hole 26 is equal to the diameter of the unlocking hole 21. The smaller diameter of the insertion rod 25 allows it to move freely up and down within the locking hole 26. Multiple positioning holes 14 are provided on the front side of the adjusting rod 15. The adjusting rod 15 is slidably installed inside the first cylinder 1. A side block 8 is fixed to the upper front end of the first cylinder 1, and a ground-inserting base 2 is fixed to the lower end of the first cylinder 1.

[0017] The side block 8 is internally threaded with a bolt 10. The bolt 10 is collinear with the first transition hole 11. The adjusting rod 15 can extend and retract inside the first cylinder 1. The height is fixed by cooperating with the bolt 10 through different positioning holes 14 to adapt to different warning needs. The ground base 2 makes it easy to insert the device firmly into the ground.

[0018] As a second embodiment of this utility model: When the height of the warning sign 3 needs to be adjusted, the bolt 10 is turned so that the bolt 10 disengages from the corresponding positioning hole 14, thereby adjusting the height of the adjusting rod 15. After adjustment, the bolt 10 is tightened so that the bolt 10 is inserted into the corresponding positioning hole 14, thereby limiting the adjustment rod 15. When the angle of the warning sign 3 needs to be adjusted, the worker pulls the second pull plate 24 upward with one hand, causing the insertion rod 25 to disengage from the locking hole 26. Then, the worker pulls the first pull plate 18 with the other hand, causing the positioning rod 20 to move. When the unlocking hole 21 is aligned with the insertion rod 25, the second pull plate 24 is released, and the insertion rod is released under the reset action of the first spring 6. Insert rod 25 into unlocking hole 21. At this time, the position of positioning rod 20 can be maintained. Then, the adjustment shaft 7 can be rotated freely to adjust the angle of warning sign 3. After adjustment, the rod 25 is disengaged from unlocking hole 21. Under the reset action of second spring 19, positioning rod 20 passes through second transition hole 12 and is inserted into corresponding insertion hole 17. At this time, rod 25 is aligned with locking hole 26. Release second pull plate 24. Under the reset action of first spring 6, rod 25 is inserted into locking hole 26, which limits the adjustment shaft 7. Under the action of natural wind, two weightless wind caps 4 can rotate. With the reflective coating, birds can be effectively frightened, preventing birds from approaching and contaminating the device.
