[0021] This type of shock-resistant sealing bracket for combustible gas sensors has achieved comprehensive performance improvements in shock resistance and sealing through optimized structural design, and can provide all-round protection for sensor components. By providing a waterproof and breathable membrane 1, it can play the role of waterproof, dustproof, breathable, etc., and can effectively extend the actual service life of the sensor. A cylindrical limit frame 7 is provided in the middle of the cavity, so that the combustible gas sensor 11 is centered and the combustible gas sensor 11 can be prevented from shaking. The sensor sealing ring 4 can play a sealing role, so that the gas will not dissipate through the gap and affect the recognition sensitivity and alarm results, so that the gas detection effect is better.

The cavity is provided with an internal thread that mates with the locking screw 51. The knob 52 is designed at the rear of the locking member 5 to facilitate subsequent removal and replacement of the sensor. The sensor bracket and the locking member 5 utilize a threaded locking design. This threaded fit secures the sensor bracket and prevents the sensor from falling off in the event of an impact. A through-hole 53 is provided in the middle of the locking screw 51 for the connecting wire of the combustible gas sensor 11 to pass through.
