[0018] 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.

[0019] See also Figure 1 An embodiment of the utility model provides a fire safety knowledge quiz device, comprising: a column 1 and an interactive button 5, and a base 2 is installed at the bottom of the column 1.

[0020] Among them, Figure 1-Figure 3 As shown, a plurality of mounting holes 10 are provided on the top of the column 1, and the interactive button 5 is installed inside the mounting hole 10. The inner wall of the mounting hole 10 is fixedly connected with an internal threaded tube 9, the outer wall of the interactive button 5 is fixedly connected with an annular plate 14, and the outer sleeve of the interactive button 5 is provided with a limiting sleeve 4, the cross-section of the limiting sleeve 4 is T-shaped, and the outer wall of the limiting sleeve 4 is connected to the inside of the internal threaded tube 9 through an external thread 8.

[0021] When in use, the number of interactive buttons 5 installed on the top of the column 1 is no less than five, of which four interactive buttons 5 are used as option buttons for fire safety questions, and the remaining button is used to quickly press to realize the function of answering questions. The limit sleeve 4 is installed on the outside of the interactive button 5 and descends to the inside of the mounting hole 10 through a threaded connection, forming a position limit for the interactive button 5 to prevent the interactive button 5 from escaping from the mounting hole 10 upward.

[0022] Furthermore, a sealing ring 7 is provided on the outer wall of the limiting sleeve 4. When the limiting sleeve 4 is rotated and fixed, the sealing ring 7 can fit between the limiting sleeve 4 and the top opening of the mounting hole 10, thereby reducing the gap between the limiting sleeve 4 and the mounting hole 10 and preventing dust from entering the mounting hole 10.

[0023] Among them, Figure 1-Figure 4 As shown, the inner bottom of the limiting sleeve 4 has no less than four grooves 11 symmetrically distributed along the circumference, and the interior of the groove 11 is connected to a pressure rod 13 through a spring 12 , and one end of the bottom of the pressure rod 13 abuts against the top of the annular plate 14 .

[0024] When the limiting sleeve 4 is threadedly connected to the internal threaded tube 9 by the external thread 8, it can continue to move downward by rotation until one end of the bottom of the pressure rod 13 abuts against the top of the annular plate 14 on the outer wall of the interactive button 5. The pressure rod 13 can continue to press the interactive button 5 downward under the continuous pressure of the spring 12, so that the stability of the power terminal can still be maintained after the interactive button 5 is used for a long time.

[0025] For further reference, Figure 1 and Figure 2 , and a plurality of anti-skid grooves 6 are distributed circumferentially on the top of the limiting sleeve 4 , and the anti-skid grooves 6 can increase the friction force on the top of the limiting sleeve 4 , making it convenient for the installer to rotate the limiting sleeve 4 .

[0026] like Figure 1 As shown, at least two annular light strips 3 are symmetrically installed on the outer wall of the column 1. The annular light strips 3 can improve the aesthetics of the column 1 and judge the state of the quick answer through the light.

[0027] The working steps of this scheme are summarized and sorted out according to the above technical scheme: when the utility model is used, no less than five interactive buttons 5 are installed on the top of the column 1, of which four interactive buttons 5 are used as option buttons for fire safety questions, and the remaining button is used for quick pressing to realize the function of answering questions.

[0028] When installing the interactive button 5, the interactive button 5 and the bottom power connection end are inserted into the mounting hole 10. At this time, the limit sleeve 4 is inserted into the outside of the interactive button 5. The limit sleeve 4 can limit the interactive button 5 from escaping upward from the mounting hole 10. The limit sleeve 4 is threadedly connected to the internal threaded tube 9 using the external thread 8, and continues to move downward by rotation until the bottom end of the pressure rod 13 abuts against the top of the annular plate 14 on the outer wall of the interactive button 5. The pressure rod 13 can continue to press down the interactive button 5 under the continuous pressure of the spring 12, so that the stability of the power connection end can still be maintained after the interactive button 5 is used for a long time, reducing the occurrence of poor contact of the interactive button 5 and reducing the shaking of the interactive button 5.
