[0031] During specific implementation, the front and rear sides as well as the top and bottom of the baffle 301 are fixedly connected to the inner wall of the protector shell 1, a vent 302 is opened at the bottom of one side of the baffle 301, and an electric push rod 303 is fixedly connected to the top center of the protector shell 1. The telescopic end of the electric push rod 303 penetrates the protector shell 1 and extends to the interior of the protector shell 1 and is fixedly connected to a blocking block 304.

[0032] Specifically, the clamping mechanism 8 includes a first clamping block 801, a movable rod 802, a first fixed plate 803, a second fixed plate 804, a sleeve spring 805 and a second clamping block 806.

The first clamping block 801 is movably clamped with the first clamping slot 6, and the interior of the first clamping block 801 is movably connected with two movable rods 802.

When it is necessary to remove the natural gas transmission pipe 4 from the protector housing 1, it is only necessary to pull the second fixed plate 804 to the side away from the second slot 7, so as to drive the movable rod 802, the second block 806 and the first fixed plate 803 to move to the side away from the natural gas transmission pipe 4, and at the same time compress the sleeve spring 805, so that the second block 806 can be disengaged from the second slot 7, and then pull the natural gas transmission pipe 4 outward, so that the first block 801 can be disengaged from the first slot 6, and the natural gas transmission pipe 4 can be disengaged from the connecting port 2, so that the natural gas transmission pipe 4 can be removed. Similarly, the assembly When the second fixing plate 804 is pulled outward to the limit position, the natural gas delivery pipe 4 is inserted into the connecting port 2, and the first clamping block 801 is inserted into the corresponding first clamping groove 6, so as to preliminarily position the natural gas delivery pipe 4, and then the second fixing plate 804 is loosened, and the second fixing plate 804 and the second clamping block 806 can be driven to perform a reset movement under the elastic force of the sleeve spring 805, so that the second clamping block 806 can be inserted into the second clamping groove 7. Through the above steps, the protector housing 1 and the natural gas delivery pipe 4 can be conveniently assembled or disassembled.
