Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1, Figure 2 and Figure 3 This utility model provides a technical solution: a smoke and heat fire detector that is easy to maintain, including a detector body 1 and a clamping assembly. To facilitate disassembly and maintenance of the detector body 1, a clamping assembly is provided on the top of the outer wall of the detector body 1. The clamping assembly includes a fixing block 201 fixedly connected to the top of the outer wall of the detector body 1. A connecting shaft 202 is fixedly connected to the top of the outer wall of the fixing block 201. A sliding block 203 is sleeved on the outer wall of the connecting shaft 202. An insertion block 204 is fixedly connected to the top of the outer wall of the connecting shaft 202. Locking blocks 205 are provided on the front and rear sides of the outer wall of the connecting shaft 202. A connecting block 206 is provided on the side of the locking block 205 away from the connecting shaft 202. A first spring 207 is provided on the side of the connecting block 206 away from the locking block 205. A mounting base 208 is fixedly connected to one side of the 06. A telescopic groove 3 is provided on the inner wall of the mounting base 208 corresponding to the position of the locking block 205. An insertion groove 4 is provided on the inner wall of the sliding block 203 corresponding to the position of the connecting shaft 202. A second spring 5 is provided at the connection between the outer wall of the connecting shaft 202 and the inner wall of the sliding block 203. An installation groove 6 is provided on the outer wall of the mounting base 208 corresponding to the position of the insertion block 204. The sliding block 203 is elastically connected to the fixed block 201. A ramp 12 is provided on the outer wall of the locking block 205. By setting up the clamping assembly, when the staff needs to disassemble the detector body 1, they only need to manually push the detector body 1 upward to separate the detector body 1 from the mounting base 208. The whole process is convenient and eliminates the inconvenience caused by the traditional fixed connection method of turning bolts.

[0022] Please see Figure 1 and Figure 4 To facilitate cleaning and maintenance of the protective cover 8, a through hole 7 is provided on the top of the outer wall of the mounting base 208. The outer wall of the detector body 1 is provided with a protective cover 8. An insertion rod 9 is fixedly connected to the top of the outer wall of the protective cover 8. A stop block 10 is fixedly connected to the top of the outer wall of the insertion rod 9. A limit hole 11 is provided on the outer wall of the detector body 1 at the corresponding position of the stop block 10. The connecting block 206 is elastically connected to the inner wall of the mounting base 208. By setting the protective cover 8, the insertion rod 9 and the stop block 10, the detector body 1 can be protected. When the staff needs to clean the protective cover 8, they only need to manually rotate the protective cover 8 to separate the protective cover 8 from the detector body 1.

[0023] Working principle: When the staff needs to disassemble the detector body 1, the staff manually pushes the detector body 1 upward. At this time, the fixing block 201 drives the connecting shaft 202 to move upward. When the sliding block 203 passes the outer wall slope 12 of the locking block 205, the locking block 205 is squeezed by the outer wall of the sliding block 203, which applies pressure to the connecting block 206. At this time, the first spring 207 is deformed by force. When the sliding block 203 moves to the appropriate position, the staff manually pulls the detector body 1 downward. At this time, the sliding block 203 is held in place by the locking block 205 and remains stationary. The insertion block 204 is close to the sliding block 203. At this time, the staff continues to pull the detector body 1 downward. Then the outer walls of the sliding block 203 and the insertion block 204 pass through the locking block 205 one after the other, completing the separation of the detector body 1. When the detector body 1 needs to be installed, the staff manually inserts the insertion block 204 into the insertion slot 4.

[0024] When the staff needs to maintain and clean the protective cover 8, they should manually rotate the protective cover 8 so that the stop 10 coincides with the limiting hole 11, and then manually pull the protective cover 8 down so that the stop 10 passes through the limiting hole 11. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
