[0030] Please refer to Figures 1-3 The present embodiment is a nitrogen charging equipment with a latex sponge built-in nitrogen bag, which comprises:

[0031] The nitrogen charging assembly comprises an inflation pipe 13 and a hose 14; the lower connecting end of the hose 14 is inserted into the peripheral connecting end of the inflation pipe 13;

[0032] The nitrogen charging assembly further comprises a body 11 and a nitrogen tank 12; the nitrogen tank 12 is arranged at the top end of the body 11 at one side edge, and the upper connecting end of the hose 14 is inserted into the connecting end of the nitrogen tank 12;

[0033] The body 11 is used for connecting other components such as the nitrogen tank 12, the nitrogen tank 12 is used for storing nitrogen, the inflation pipe 13 is used for charging nitrogen into the body 11, and the hose 14 is used for transporting the nitrogen in the nitrogen tank 12 into the inflation pipe 13.

[0034] The auxiliary connecting assembly comprises a clamping block 21, a vertical plate 22, a connecting frame 23, a spring 24 and a clamping plate 25. The clamping block 21 is clamped at the periphery of the connection between the hose 14 and the inflation pipe 13. The vertical plate 22 is arranged at both ends of the opening of the clamping block 21. The connecting frame 23 is arranged below the connecting end of the inflation pipe 13. The vertical plate 22 is arranged inside the connecting frame 23. The spring 24 is arranged at both ends inside the connecting frame 23. The clamping plate 25 is arranged at the opposite ends of the spring 24.

[0035] The clamping block 21 is used for clamping the connection between the hose 14 and the inflation pipe 13. The vertical plate 22 is used for connecting the clamping block 21 and the connecting frame 23. The connecting frame 23 is used for connecting the spring 24. The spring 24 is used for connecting the clamping plate 25. The clamping plate 25 is used for extruding the vertical plate 22 after clamping.

[0036] A group of fixing blocks 26 are connected to the inner side ends of the connecting frame 23. The other ends of the fixing blocks 26 are connected below the outer side ends of the inflation pipe 13. A partition block 27 is connected to the inner side center of the connecting frame 23. The partition block 27 is arranged between the inner sides of the vertical plate 22.

[0037] The fixing blocks 26 are used for connecting the connecting frame 23 and the outer side ends of the inflation pipe 13. The partition block 27 is used in cooperation with the clamping plate 25 to clamp the vertical plate 22. The partition block 27 is used for connecting the magnetic blocks 28.

[0038] The magnetic blocks 28 are connected to both sides of the partition block 27. The connecting blocks 29 are connected to the opposite ends of the vertical plate 22. The connecting blocks 29 are attracted to the magnetic blocks 28.

[0039] The magnetic blocks 28 are used for attracting the connecting blocks 29. The inner side of the bottom end of the vertical plate 22 is attracted to both sides of the partition block 27. The clamping block 21 is limited after clamping. The clamping block 21 is placed above the connection between the hose 14 and the inflation pipe 13. The clamping block 21 is extruded with the hose 14 and the inflation pipe 13. The clamping block 21 drives the vertical plate 22 to move away in the connecting frame 23. The vertical plate 22 extrudes the clamping plate 25. When the clamping block 21 is completely clamped with the hose 14 and the inflation pipe 13, the clamping plate 25 extrudes the vertical plate 22. The connecting blocks 29 inside the vertical plate 22 are attracted to the magnetic blocks 28.

[0040] The working principle of this utility model is as follows: When the component is not in use, the connection between the snap-fit ​​block 21 and the hose 14 and the inflation tube 13 is in a separated state. When the component is in use, hold the snap-fit ​​block 21 by hand and place it above the connection between the hose 14 and the inflation tube 13. Push the snap-fit ​​block 21 so that the connection between the snap-fit ​​block 21 and the hose 14 and the inflation tube 13 is pressed together. Since the snap-fit ​​block 21 is made of PVC board, it has toughness, so the inner side of the snap-fit ​​block 21 gradually expands. The snap-fit ​​block 21 drives the vertical plate 22 to move back and forth within the connecting frame 23, causing the vertical plate 22 to move. Plate 22 presses against clamping plate 25, and clamping plate 25 moves in opposite directions via spring 24. When the connection between snap-fit ​​block 21 and hose 14 and inflation tube 13 is completely snapped together, the force of the squeezing spring 24 disappears, and spring 24 pushes clamping plate 25 to press against vertical plate 22, causing vertical plate 22 to move to its original position, causing connecting block 29 on the inner side of vertical plate 22 to attract magnetic block 28. At this time, clamping plate 25 and magnetic block 28 limit snap-fit ​​block 21 after snapping through vertical plate 22, thereby further snapping and limiting snap-fit ​​block 21 at the connection between hose 14 and inflation tube 13.

[0041] The above steps prevent the connection between the hose 14 and the inflation tube 13 from becoming loose or separating.

[0042] Please see Figure 1 , Figures 4-5 As shown, this embodiment, based on the above embodiment, further includes:

[0043] Limiting components;

[0044] The limiting assembly includes a fixed rod 31, a movable rod 32, a clamping block 33, and a crossbar 34. The fixed rod 31 is located at one side corner of the front of the machine body 11. The movable rod 32 is slidably connected to the inside of the outer end of the fixed rod 31. The clamping block 33 is threadedly connected to the outer end of the movable rod 32. The crossbar 34 is located on one side of the front of the machine body 11 and is located on one side of the fixed rod 31.

[0048] The docking block 36 and the magnetic attraction block 35 are used for connecting the clamping block 33 and the cross rod 34 together, and the friction surface 37 is used for increasing the friction between the hose 14 and the clamping block 33, so that the clamping block 33 can clamp the hose 14 better.

[0049] The working principle of the utility model is as follows: when the assembly is not used, the moving rod 32 is in the retracted state, the hose 14 is separated from the clamping block 33, when the assembly is used, the moving rod 32 is pulled out by hand, so that the moving rod 32 drives the clamping block 33 to move outward, the clamping block 33 drives the docking block 36 and the magnetic attraction block 35 to be attracted, the magnetic attraction block 35 limits the clamping block 33 after moving, then the upper part of the hose 14 is clamped in the clamping block 33 by hand, so that the clamping block 33 is connected with the hose 14 through the inner friction surface 37, the friction surface 37 increases the friction between the hose 14 and the clamping block 33, so that the clamping block 33 limits the hose 14, thereby avoiding the sinking of the hose 14 at the bending position.
