[0002] By using mobile inspections of smoke detectors, the comprehensiveness of fire area inspections is improved while problems can be discovered and alarmed in a timely manner.

[0003] The existing smoke detector inspection method mainly drives the movement of the smoke detector through the meshing of gears and racks. For example, the authorization publication number CN218273634U is a fire smoke inspection device. Due to the difference in the size of the detection area, in actual use, the inspection rails of the smoke detector need to be connected and assembled. When assembling the existing inspection rails, bolts are mainly used for connection. Although the operation is relatively simple, the small contact area of ​​the bolt connection point causes stress concentration at the connection, which causes fatigue damage to the bolts or connection parts during long-term use, thereby affecting the connection stability and accuracy of adjacent inspection rails.

[0033] It should be noted that: only one smoke detector 104, inspection plate 103, fixed plate 106, rotating gear 107, rotating motor 108 and other components are provided. At the same time, for the specific inspection method and working steps of the smoke detector 104, please refer to the authorized disclosure CN218273634U, a fire smoke inspection device, which will not be repeated here.

[0034] like Figure 4As shown: the driving mechanism includes two driving plates 301 symmetrically arranged in a sliding connection in a connection box 203, and the outer sides of the two driving plates 301 are hinged with connecting rods 302, and the other ends of the connecting rods 302 are rotatably connected to the corresponding latches 204;

[0035] The connection box 203 is provided with a moving assembly for moving the two driving plates 301 .

[0036] It should be noted here that: by setting the driving mechanism, it is convenient to drive the two relatively arranged latches 204 to move towards or away from each other.

[0037] like Figure 4 As shown: the moving assembly includes a double-headed threaded rod 5 rotatably connected to the connection box 203, the two driving plates 301 are respectively threadedly connected to the side walls of the double-headed threaded rod 5, and the connection box 203 is provided with a rotating assembly for rotating the double-headed threaded rod 5.

[0038] By setting the moving assembly, it is convenient to drive the two driving plates 301 to rotate towards or away from each other.

[0039] See also Figure 4 The rotating assembly includes a rotating rod 601 rotatably connected to the connecting box 203; the inner end of the rotating rod 601 is fixedly connected to a first bevel gear 602, the side wall of the double-threaded rod 5 is fixedly connected to a second bevel gear 603, and the second bevel gear 603 and the first bevel gear 602 are meshed with each other; the outer end of the rotating rod 601 is provided with a rotating hole 604 in a regular hexagonal shape. The setting of the rotating assembly facilitates the rotation of the double-threaded rod 5.

[0040] like Figure 4 As shown in the figure: the connection box 203 is provided with a guide assembly for guiding the two drive plates 301; the guide assembly includes guide grooves 4 provided on two opposite inner walls of the connection box 203, the two guide grooves 4 are slidably connected with guide plates, and the opposite ends of the two guide plates are connected to the drive plates 301. The setting of the guide assembly provides guidance and limiting functions for the movement of the drive plates 301.

[0041] In addition, a positioning assembly for positioning during the connection process is provided between two adjacent prefabricated panels 101, and the positioning assembly includes a T-shaped slot 701 provided at one end of the prefabricated panel 101, and a T-shaped plate 702 is fixedly connected to the other end of the prefabricated panel 101, and the T-shaped plate 702 is matched with the T-shaped slot 701. The positioning assembly plays a guiding and positioning role when two adjacent prefabricated panels 101 are connected, thereby improving the connection accuracy of the two adjacent prefabricated panels 101 and increasing the connection contact area between the two adjacent prefabricated panels 101.

[0042] Working principle: When assembling the inspection components of the smoke detector 104, first, use the positioning assembly to position and align one end of two adjacent prefabricated panels 101, then place the connection box 203 in the installation groove 201 formed by the connection ends of the two prefabricated panels 101, and use the hexagonal wrench to rotate the rotating rod 601. During the rotation of the rotating rod 601, the first bevel gear 602 is driven to rotate, and the double-headed threaded rod 5 is driven to rotate under the mutual meshing transmission action of the first bevel gear 602 and the second bevel gear 603;

[0043] During the rotation of the double-headed threaded rod 5, the two driving plates 301 will be driven to move away from each other under the action of the threaded meshing transmission and the guiding action of the guide assembly. During the movement of the two driving plates 301 away from each other, the two connecting rods 302 on the same side will be driven to rotate away from each other. During the rotation of the two connecting rods 302 away from each other, the two latches 204 will be pushed to move away from each other, so that the two latches 204 enter the connecting hole 202 and abut against the bottom wall of the connecting hole 202. Therefore, under the pressing action of the latch 204, the connection between the two adjacent prefabricated panels 101 is limited, and the assembly of the inspection components of the smoke detector 104 is further completed. The operation is simple and the implementation is convenient. Through the pressing action of the latch 204, the contact area of ​​the connection point is increased, and the stress concentration at the connection is reduced, thereby ensuring the stability and accuracy of the connection between the adjacent prefabricated panels 101.
