[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0036] like Figure 1-7 As shown, this embodiment proposes a temperature-sensing smoke detection device for fire detection, including a detection device body 1, a sleeve 2 is movably connected to the top of the detection device body 1, a disassembly mechanism 3 is provided between the sleeve 2 and the detection device body 1, and a fixing component 4 is provided on the top of the sleeve 2;

[0037] The disassembly mechanism 3 includes an insertion column 301, a ball groove 302, a ball 303, an annular groove 304, a sleeve 305, an annular fixing plate 306, an annular limiting block 307, a spring 308 and a limiting assembly 309. The insertion column 301 is fixedly connected to the top of the detection device body 1 and plugged into the sleeve 2. Multiple ball grooves 302 all penetrate the sleeve 2. The ball 303 is arranged inside the ball groove 302. The annular groove 304 is opened on the surface of the insertion column 301 and is used in conjunction with the ball 303. The sleeve 305 is sleeved on the periphery of the sleeve 2. The annular fixing plate 306 is fixedly connected to the surface of the sleeve 2 and is slidably connected to the sliding sleeve 305. The annular limiting block 307 is fixedly connected to the inner wall of the sliding sleeve 305 and is used in conjunction with the ball groove 302. One end of the spring 308 is fixedly connected to the bottom of the annular fixing plate 306, and the other end of the spring 308 is fixedly connected to the top of the annular limiting block 307. The limiting component 309 is arranged between the annular fixing plate 306 and the sliding sleeve 305. When in use, the staff first holds the sliding sleeve 305, and then provides an upward force to the sliding sleeve 305. The sliding sleeve 305 will drive the annular limiting block 307 to move upward, and the annular limiting block 307 will release the restriction on the ball 303 in the ball groove 302. At the same time, the spring 308 is in a contracted state between the annular limiting block 307 and the annular fixing plate 306. Then the detection device body 1 is inserted into the interior of the sleeve 2 through the insertion column 301. The top of the insertion column 301 will exert a force on the ball 303 at the first time. The ball 303 will move to the gap between the sliding sleeve 305 and the ball groove 302. When the annular clamp on the surface of the insertion column 301 When the position of the groove 304 corresponds to the position of the ball groove 302, the sleeve 305 is released, and the sleeve 305 moves downward due to the deformation force of the spring 308. At the same time, the annular limiting block 307 exerts a force on the ball 303, so that the ball 303 moves to the inside of the ball groove 302. The annular limiting block 307 restricts the ball 303 so that a part of the ball 303 is inside the annular slot 304. At this time, the insertion column 301 can be restricted, thereby facilitating the later disassembly of the detection equipment body 1. The operation is convenient and the work efficiency is greatly improved.

[0040] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, a plurality of annular rubber strips 5 are fixedly connected to the surface of the sleeve 305, and the plurality of annular rubber strips 5 are evenly and equidistantly distributed on the surface of the sleeve 305, which can increase the friction between the palm of the staff and the sleeve 305 and avoid slipping.

[0041] like Figure 7 As shown, as a preferred embodiment, on the basis of the above method, further, the bottom of the annular limiting block 307 is provided with an inclined portion 6 used in conjunction with the ball 303. When the sleeve 305 drives the annular limiting block 307 to move downward under the deformation force of the spring 308, the inclined portion 6 is provided to facilitate squeezing the ball 303 into the interior of the ball groove 302, thereby avoiding jamming.

[0042] like Figure 4 As a preferred embodiment, on the basis of the above method, further, the inner wall of the sleeve 2 is fixedly connected with an annular blocking plate 7 used in conjunction with the insertion column 301, which can limit the insertion column 301 inserted into the sleeve 2, thereby improving the accuracy of the corresponding position of the annular groove 304 and the ball groove 302.

[0043] like Figure 6 and Figure 7 As shown, as a preferred embodiment, on the basis of the above method, further, multiple ball grooves 302 are evenly distributed on the sleeve 2, and the aperture of the ball groove 302 close to the annular limiting block 307 is larger, which can ensure that the ball 303 will not move out from the small aperture end of the ball groove 302, thereby having the effect of limiting the ball 303 in the ball groove 302.

[0044] Specifically, when the temperature-sensing and smoke-sensing detection device for fire detection is in use: an expansion screw is used to pass through the mounting hole 403 on the fixing ear 402, so that the mounting seat 401 together with the sleeve 2 can be fixed to the top of the room, and then the staff first holds the sliding sleeve 305, and then provides an upward force to the sliding sleeve 305, and at the same time the sliding sleeve 305 will drive the annular limiting block 307 to move upward, at this time the annular limiting block 307 will release the restriction on the ball 303 in the ball groove 302, and at the same time the spring 308 is in a contracted state between the annular limiting block 307 and the annular fixing plate 306, and then the detection device body 1 is inserted into the interior of the sleeve 2 through the insertion column 301, and the top of the insertion column 301 will apply a force to the ball 303 for the first time, and the ball 303 will move to the gap between the sliding sleeve 305 and the ball groove 302 at this time. When the positions are corresponding, the sleeve 305 is released, and the sleeve 305 moves downward through the deformation force of the spring 308, and the annular limiting block 307 applies a force to the ball 303, so that the ball 303 moves to the inside of the ball groove 302, and the annular limiting block 307 limits the ball 303 so that a part of the ball 303 is inside the annular groove 304. At this time, the insertion column 301 can be restricted, so as to facilitate the later disassembly of the detection equipment body 1, the operation is convenient, and the work efficiency is greatly improved. When the sleeve 305 moves under the force, the limit block 3091 on the side wall of the annular fixing plate 306 will move along the trajectory of the limit groove 3092 on the inner wall of the sleeve 305, so as to limit the movement process of the sleeve 305, and prevent the bottom end of the sleeve 305 from completely releasing the restriction on the ball 303 in the ball groove 302, and prevent the ball 303 from rolling out of the ball groove 302.

[0045] All technical features in this embodiment can be freely combined according to actual needs.
