Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1-4 shown, a technical solution provided by the present invention:

[0025] A safe and flame-retardant point valve box, including a point valve box body 1, an air storage mechanism is arranged inside the point valve box body 1. The air storage mechanism includes a mounting rack 4. The mounting rack 4 is arranged at the upper and lower ends of the inner wall on the side of the point valve box body 1 away from the box door 2. A gas storage tank 5 is fixedly installed between the two mounting racks 4. The air storage mechanism further includes an intake pipe 6. The intake pipe 6 communicates with the upper end of the gas storage tank 5. The top end of the intake pipe 6 is connected to a ball valve I 8 through a flame arrester pipe 7. The air storage mechanism further includes a horizontal rack 9. The horizontal rack 9 is horizontally arranged below the side of the point valve box body 1 close to the box door 2. A connecting pipe 10 is connected to the bottom end of the gas storage tank 5. The box door 2 is movably installed outside one side of the point valve box body 1. A plurality of inner grooves 3 are arranged side by side at the bottom end of the box door 2. A stretching mechanism is arranged inside each of the plurality of inner grooves 3. The stretching mechanism includes a bellows 11. The end of the connecting pipe 10 passes through the horizontal rack 9 and is connected to a plurality of bellows 11 through a branch pipe. One end of the horizontal rack 9 away from the connecting pipe 10 is connected to the inner side of the end of the bellows 11 through a spring 12. The end of the bellows 11 is connected to a ball valve II 14 through a rotary joint 13;

[0026] In this embodiment, during use, pull the second ball valve 14. When the second ball valve 14 is pulled, it drives the rotary joint 13 to move outward. When the rotary joint 13 moves, it stretches the bellows 11 and the spring 12 until the second ball valve 14 and the rotary joint 13 are completely pulled out from the inner groove 3. Then rotate the rotary joint 13 so that the positioning rods 16 at both ends of the rotary joint 13 are positioned with the locking holes 18 on the box door 2. Then release the second ball valve 14. At this time, the stretched spring 12 will pull back the rotary joint 13, causing the positioning rod 16 to insert into the locking hole 18 for fixation. In this way, during use, the second ball valve 14 can be arranged outside the box door 2 and then retracted into the inner groove 3 after use. In this way, when connecting the pipeline, there is no need to open the box door 2, and it can be hidden after use, avoiding being damaged by impact.

[0027] As Figure 4 shown, a positioning mechanism is arranged between the box door 2 and the stretching mechanism. The positioning mechanism includes a positioning block 15. The positioning block 15 is fixedly installed on the outer sides of both sides of the bellows 11. Positioning rods 16 that are positioned and sleeved with the positioning block 15 are arranged at both ends of the rotary joint 13. Side grooves 17 are opened on both sides of the inner groove 3. Locking holes 18 are arranged on the outer sides of the other two ends of the box door 2 close to the side grooves 17;

[0028] In this embodiment, when the rotary joint 13 is retracted into the inner groove 3, the positioning rods 16 at both ends of the rotary joint 13 will extend along the side grooves 17 on both sides of the inner groove 3. In this way, the holes of the positioning rods 16 and the positioning blocks 15 on both ends of the bellows 11 end are on the same horizontal line. At this time, after the spring 12 pulls back, the positioning rod 16 can be accurately inserted into the positioning block 15 for fixation, so as to achieve the purpose of facilitating positioning and sleeving.

[0029] Working principle: During use, pull the second ball valve 14. When the second ball valve 14 is pulled, it drives the rotary joint 13 to move outward. When the rotary joint 13 moves, it stretches the bellows 11 and the spring 12 until the second ball valve 14 and the rotary joint 13 are completely pulled out from the inner groove 3. Then rotate the rotary joint 13 so that the positioning rods 16 at both ends of the rotary joint 13 are positioned with the locking holes 18 on the box door 2. Then release the second ball valve 14. At this time, the stretched spring 12 will pull back the rotary joint 13, causing the positioning rod 16 to insert into the locking hole 18 for fixation. In this way, during use, the second ball valve 14 can be arranged outside the box door 2 and then retracted into the inner groove 3 after use. In this way, when connecting the pipeline, there is no need to open the box door 2, and it can be hidden after use, avoiding being damaged by impact. When the rotary joint 13 is retracted into the inner groove 3, the positioning rods 16 at both ends of the rotary joint 13 will extend along the side grooves 17 on both sides of the inner groove 3. In this way, the holes of the positioning rods 16 and the positioning blocks 15 on both ends of the bellows 11 end are on the same horizontal line. At this time, after the spring 12 pulls back, the positioning rod 16 can be accurately inserted into the positioning block 15 for fixation.
