[0033] like Figure 2As described, the warning sign housing 9 is connected to the support rod 7 at the bottom; the support rod 7 includes an upper support rod 7 and a lower support rod 7; the upper support rod 7 is installed on the lower support rod 7 and slides on the lower support rod 7; a fixing device 3 for fixing the upper support rod 7 and the lower support rod 7 is installed on the lower support rod 7; the fixing device 3 is used to fix the upper support rod 7 and the lower support rod 7 by bolts.

[0034] A plurality of magnets 1 for reinforcing the warning plate are arranged on the warning plate housing 9, and the magnets 1 are used to reinforce the warning plate to prevent the warning plate from falling.

[0035] like Figure 3 As described, the support rod 7 is installed on the mounting plate; a plurality of pulleys 8 are installed below the mounting plate; the plurality of pulleys 8 are universal wheels with locking devices.

[0036] A handle 6 for convenient movement of the warning sign is installed on the warning sign housing 9; a warning light 5 and an inner clip are installed on the warning sign housing 9; the warning light 5 is connected to a power source, and the warning light 5 is connected to a switch; by turning on the warning light 5, relevant personnel can be reminded to read the warning content of the warning sign.

[0037] Example 2

[0038] Based on Example 1, the working principle of the utility model is: in the factory, the warning content is clamped on the safety warning sign, the warning sign support rod 7 is pulled to the required height and fixed, and then the pulley 8 under the support rod 7 is locked; at this time, the warning light 5 is turned on to remind every employee in the factory that they need to read the warning content on the warning sign; when an employee passes by and starts to read the warning sign, the counter is incremented by one and displayed on the first digital tube, and the timer starts timing; when the employee finishes reading and leaves, the infrared ray is not blocked, and the timer ends at this time, and the final number of the timing is displayed on the second digital tube; in this way, as multiple employees pass by and read, the accumulated number of people and the accumulated time are respectively displayed on the first digital tube and the second digital tube. The factory manager compares the estimated reading time per person during the day with the number of people who should read the warning. For example, if there are 50 employees in the factory, the estimated flow of people reading the warning signs in the factory is 50 people, and the actual time required to read the warning content is at least one minute per person. When the warning content is announced, the time on the timer is 70 minutes, and the actual counter counts 80 times. The actual statistical time on the timer and the actual counter counts are compared with the estimated flow of people reading the warning signs in the factory of 50 people and the actual time required to read the warning content is at least one minute per person. This helps managers determine that the factory employees have carefully read and browsed the safety warning signs, and that the factory employees who should read the signs have read the warning signs.

[0039] Example 3

[0040] Based on Example 1 and Example 2, the working principle of the utility model is: in the factory, the warning content is clamped on the safety warning sign, the warning sign support rod 7 is pulled to the required height and fixed, and then the pulley 8 under the support rod 7 is locked; at this time, the warning light 5 is turned on to remind every employee in the factory that they need to read the warning content on the warning sign; when an employee passes by and starts to read the warning sign, the counter is incremented by one and displayed on the first digital tube, and the timer starts timing; when the employee finishes reading and leaves, the infrared ray is not blocked, and the timer ends at this time, and the final number of the timing is displayed on the second digital tube; in this way, as multiple employees pass by and read, the accumulated number of people and the accumulated time are respectively displayed on the first digital tube and the second digital tube. The factory manager compares the estimated reading time per person during the day with the number of people who should read the warning sign. For example, if there are fifty employees in the factory, the estimated flow of people reading the warning sign in the factory is fifty people, and the actual time required to read the warning content is at least one minute per person. When the warning content is announced, the time on the timer is twenty-five minutes, and the actual counter counts twenty times. The actual statistical time on the timer and the actual counter counts are compared with the estimated flow of people reading the warning sign in the factory of fifty people and the actual time required to read the warning content is at least one minute per person. This helps managers determine that factory employees have not carefully read and browsed the safety warning signs, and that not all factory employees who should read the signs have read them. Managers can use this warning situation to adjust the layout of warning signs and strengthen safety warning education for factory employees.

[0041] As described in the above working principle, the utility model can assist managers in determining whether factory employees have carefully read and browsed the safety warning signs, and whether all factory employees who should read the signs have read the warning signs.
