Obviously, the described embodiment is a part 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 creative work are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1 , Figure 3 and Figure 4 As shown, a fiber Bragg grating linear temperature-sensing fire detector comprises a processor 1 and a clamping assembly 2. The rear side of the processor 1 is provided with a clamping assembly 2 for easy installation. The clamping assembly 2 comprises a mounting rod 201, a limiting rod 202, a limiting groove 203, a mounting block 204, a spring 205 and a base 206. Limiting rods 202 are provided on the left and right sides of the outer wall of the mounting rod 201. The limiting groove 203 is provided at the corresponding position of the outer wall of the mounting rod 201 and the limiting rod 202. The outer wall of the limiting rod 202 is sleeved with a mounting block 204. The limiting rod 202 is provided with a spring 205 on the side away from the mounting rod 201. The spring 205 is provided with a base 206 on the side away from the limiting rod 202. The mounting block 204 is fixedly connected to the inner wall of the base 206.

[0021] The operation is as follows: first, the base 206 is installed at the monitoring location through the fixing block 3. Then, when the staff needs to inspect the processor 1, the mounting rod 201 is manually removed from the slot 4. At this time, the limiting rod 202 is disengaged from the limiting slot 203, and the limiting effect on the mounting rod 201 is released. When the inspection of the processor 1 is completed, the mounting rod 201 is inserted into the slot 4. The limiting rod 202 is subjected to external force to apply pressure to the spring 205. At the same time, the limiting rod 202 moves inside the mounting block 204. When the limiting rod 20 2 is in a suitable position, the limiting rod 202 is in the limiting groove 203, and the spring 205 is used to limit and clamp the mounting rod 201. By setting the clamping assembly 2, when the worker installs the processor 1, he only needs to insert the mounting rod 201 into the base 206. The mounting rod 201 is limited and fixed to the processor 1 by the limiting rod 202. When the processor 1 needs to be repaired, he only needs to pull the mounting rod 201 out of the slot 4. The whole process is simple and convenient for the worker to operate.

[0023] The specific operation is as follows. When the staff needs to connect the wire 5, the wire 5 is connected and placed in the sleeve 6, and then the connecting rod 7 is rotated so that the connecting rod 7 and the sleeve 6 are in a suitable position. At this time, the limit ring 10 is manually rotated so that the fixing ring 11 applies pressure to the fastener 8, so that the fastener 8 applies pressure to the wire 5 to fix the wire 5. By setting the sleeve 6, the connecting rod 7 and the fastener 8, when the staff connects the wire 5, the limit ring 10 can be rotated so that the fastener 8 clamps and fixes the wire 5, thereby completing the reinforcement of the connected wire 5 to prevent it from being damaged by external force and causing connection interruption.

[0024] Working principle of this utility model:

[0025] Refer to the instruction manual Figures 1 to 4 When using the utility model, firstly, the base 206 is installed at the monitoring location through the fixing block 3. Then, when the staff needs to inspect the processor 1, the mounting rod 201 is manually taken out from the slot 4. At this time, the limiting rod 202 is disengaged from the limiting groove 203, and the limiting effect on the mounting rod 201 is released. When the inspection of the processor 1 is completed, the mounting rod 201 is inserted into the slot 4. The limiting rod 202 is subjected to external force to apply pressure to the spring 205. At the same time, the limiting rod 202 moves inside the mounting block 204. When When the limit rod 202 is in a suitable position, the limit rod 202 is inside the limit groove 203, and the spring 205 is used to limit and clamp the installation rod 201. When the staff needs to connect the wire 5, the wire 5 is connected and placed in the sleeve 6, and then the connecting rod 7 is rotated so that the connecting rod 7 and the sleeve 6 are in a suitable position. At this time, the limit ring 10 is manually rotated so that the fixing ring 11 applies pressure to the fastener 8, so that the fastener 8 applies pressure to the wire 5 to fix the wire 5. The above is the working principle.
