[0002] Heat stroke is the most serious type of heat stroke, usually occurring in hot and humid weather. When the human body is exposed to such an environment for a long time, the skin's heat dissipation function will decrease, causing the muscle temperature to rise, which in turn affects the functions of organs and tissues throughout the body. The heat stroke prevention device is a portable device designed to reduce the risk of heat stroke.

[0003] However, the portable heat stroke prevention devices currently on the market do not have a fixing device. When ordinary prevention devices are carried by workers, the devices may fall due to the workers' activities, causing damage to the devices, thereby increasing the equipment cost. Therefore, a heat stroke prevention device with a limiting mechanism is proposed. Utility Model Content

[0007] Furthermore, the number of the U-shaped blocks and the number of the limiting columns are both two, and the two U-shaped blocks and the two limiting columns are respectively located on the left and right sides of the preventer body.

[0008] Furthermore, the number of the springs and the first trapezoidal blocks is two, and the opposite sides of the two springs are respectively fixedly connected to the sides of the two first trapezoidal blocks away from the preventer body, and the opposite sides of the two first trapezoidal blocks are fixedly installed with connecting plates, and the opposite sides of the connecting plates are fixedly installed with second trapezoidal blocks.

[0009] Furthermore, the opposite sides of the two second trapezoidal blocks respectively penetrate the inner left wall and the inner right wall of the base and are plugged into the inner parts of the two U-shaped blocks.

DETAILED DESCRIPTION

[0020] 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.

During use, the temperature, humidity, toxic gas content and oxygen content of the external space will be monitored, and then the data will be displayed. Then, the user will be warned by analyzing various data.

[0024] Specifically, Figure 2As shown, when the preventer body 1 needs to be taken out, the pressing block 306 is pressed to drive the installation rod to move downward, and the first trapezoidal block 305 is pushed and the spring 304 is squeezed by the matching roller 307. Then, the movement of the first trapezoidal block 305 drives the connecting plate and the second trapezoidal block to move, thereby retracting the second trapezoidal block into the base 303, and then the preventer body 1 can be directly pulled out of the protective cover 308.

[0025] Specifically, Figure 4 As shown, the material of the spring 304 is beryllium bronze, which contains 1.7-2.5% beryllium. The addition of beryllium has excellent elasticity.

[0030] 4) Finally, the limiting column 302 will slide in the sliding groove formed by the two guide blocks 309 and finally be auxiliary fixed on the limiting piece 310.

[0031] To summarize, the protective cover 308 and the base 303 are fixed to the belt or shoulder strap through buckles, and then the preventer body 1 is placed from the top of the protective cover 308 into the base 303. During the process, the two U-shaped blocks 301 will push the two second trapezoidal blocks back into the base 303 and squeeze the spring 304. When the bottom of the preventer body 1 reaches the inner bottom wall of the base 303, the second trapezoidal block will be pushed out of the base 303 and inserted into the U-shaped block 301 under the action of the spring 304, so as to limit and fix the device. Then the limiting column 302 will move downward along the area formed by the two guide blocks 309 until it enters the limiting plate 310 for secondary limiting and fixing, thereby achieving the purpose of limiting and fixing the preventer body 1 during carrying.
