[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 6 As shown, the utility model provides a fire passage safety detection device, including a mounting seat 1 and a device body 2, a rotating ring 3 is provided on the surface of the device body 2, so that the inner wall of the rotating ring 3 can slide on the surface of the device body 2, and a plurality of sliding grooves 10 are provided on the inner wall of the device body 2, and a guide rod 11 is fixedly connected to the inner wall of each sliding groove 10, and the sliding groove 10 and the guide rod 11 are both arc-shaped, and a sleeve 12 is elastically provided on the surface of each guide rod 11, so that the sleeve 12 can slide on the guide rod 11, and one end of each sleeve 12 is fixedly connected to the surface of the rotating ring 3, and the other end of each sleeve 12 is fixedly connected to a card plate 8. Under the setting of the above structure, a person can control each card plate 8 to rotate at the top end of the device body 2 by rotating the rotating ring 3. A card slot 9 is provided in the middle of each card plate 8, and the inner wall of the mounting seat 1 is fixed There are several limit plates 14 that are compatible with the card plates 8 and the card slots 9, and the card slots 9 are snapped into one end of the corresponding limit plates 14. Through the setting of the above structure, the device body 2 can be easily fixed on the mounting base 1, and it is also easier to remove for maintenance. During specific operation, it is only necessary to send the device body 2 directly toward the bottom of the mounting base 1 so that the top of each card plate 8 will contact the corresponding limit plate 14. Due to the continuous pushing of the device body 2, the card plate 8 will be squeezed and slid until the limit plate 14 is aligned with the card slot 9. The card plate 8 can be automatically snapped and fixed with the limit plate 14, and the operation is more convenient. When it is necessary to remove the device body 2, it is only necessary to rotate the rotating ring 3 to drive each card plate 8 away from the corresponding limit plate 14, so that the limit plate 14 is away from the card slot 9, and then directly pull the rotating ring 3 downwards.

[0022] like Figure 2 and Figure 5 As shown, a plurality of positioning posts 7 are fixedly connected to the top of the device body 2, and a plurality of positioning holes 13 adapted to the positioning posts 7 are opened on the bottom surface of the mounting base 1, and the positioning posts 7 are inserted into the positioning holes 13. Through the arrangement of the positioning posts 7 and the positioning holes 13, the stability between the mounting base 1 and the device body 2 can be ensured, and the device body 2 can be prevented from rotating at the bottom of the mounting base 1 at will, so that the device body 2 can be removed only by rotating the rotating ring 3.

[0023] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the surface of the mounting base 1 is provided with a first marking line 5 corresponding one-to-one to the positioning hole 13, and the surface of the device body 2 is provided with a second marking line 4 corresponding one-to-one to the positioning column 7. Through the setting of the second marking line 4 and the first marking line 5, it is convenient for personnel to clearly observe whether the second marking line 4 and the first marking line 5 are aligned, so that the mounting base 1 and the device body 2 can be easily assembled and fixed, which has an auxiliary effect on the installation operation steps of the personnel.

[0024] like Figure 4 、 Figure 5 and Figure 6 As shown, the surface of the rotating ring 3 is provided with anti-slip grooves, which can facilitate personnel to easily rotate the rotating ring 3, so as to quickly control the sliding of each card plate 8, and achieve the purpose of removing the device body 2 from the mounting seat 1. One end of each limit plate 14 is provided with a chamfer. The chamfer setting can prevent the top of the card plate 8 from being worn by the tip of the limit plate 14, and also improve the sliding effect between the card plate 8 and the limit plate 14.

[0025] like Figure 4 As shown, the surface of each guide rod 11 is sleeved with a compression spring 6, and the two ends of the compression spring 6 are respectively fixed to the surface of the sleeve 12 and the inner wall of the sliding groove 10. Through the setting of the compression spring 6, it can be ensured that the sleeve 12 and the card plate 8 have an elastic sliding effect in the sliding groove 10. When the person rotates the rotating ring 3, each card plate 8 will be driven to rotate together. When it is released, the elastic action of the compression spring 6 will be used to automatically reset each compression spring 6.

[0026] The working principle and usage process of the present invention are as follows: when assembling and fixing the device main body 2 and the mounting base 1, it is only necessary to move the device main body 2 directly toward the bottom of the mounting base 1 so that the positioning column 7 is inserted into the corresponding positioning hole 13, and then the top of each card plate 8 will squeeze the corresponding limit plate 14. Since the top of the card plate 8 is an inclined surface, the card plate 8 can slide to one side until the limit plate 14 is aligned with the card slot 9. The elastic force of the compression spring 6 is used to automatically connect and fix the card plate 8 with the limit plate 14, which makes the operation more convenient. When the device main body 2 needs to be removed, it is only necessary to rotate the rotating ring 3 to drive each card plate 8 away from the corresponding limit plate 14, so that the limit plate 14 is away from the card slot 9, and then directly pull the rotating ring 3 downward.
