Description

Technical Field

[0001] The present invention relates to a sealing structure for the air rib splint of a high-pressure inflatable tent, belonging to the technical field of high-pressure air rib fixation. Background Art

[0002] Inflatable tents are widely used in tourism, field training, and various disaster relief occasions. When using an inflatable tent, it is necessary to fix the tail of the air rib. The existing fixtures for fixing the tail of the air rib have a complex structure and are prone to problems such as fixture loosening and slipping.

[0003] For example, a high-pressure air rib fixing tooling disclosed in Patent CN202320993104.1 includes a frame and two splints. A first support is provided on the frame, and second supports for mating installation with the first support are provided on both splints. The first support on the frame and the second supports on the two splints are detachably connected by fixing pins. The two splints are detachably connected, and the air rib is clamped between the two splints. The structure of this tooling is relatively complex, and the air rib is only clamped by the splints, resulting in a poor fixing effect on the air rib and a risk of detachment and air leakage. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a sealing structure for the air rib splint of a high-pressure inflatable tent with a simple structure and firm clamping.

[0005] To achieve the above object, the technical solution proposed by the present invention is: a sealing structure for the air rib splint of a high-pressure inflatable tent, including a fixture, a pressing plate, and a base. The fixture is connected to the base and is provided with a U-shaped groove. One end of the U-shaped groove of the fixture is provided with a plurality of screw holes, and a tightening bolt is screwed in the screw holes. The pressing plate is arranged in the U-shaped groove of the fixture and one side thereof abuts against the tightening bolt. The tail of the air rib of the high-pressure inflatable tent is embedded in the U-shaped groove and is located between the side wall at the other end of the U-shaped groove and the side of the pressing plate away from the tightening bolt. By turning the tightening bolt, the tightening bolt pushes the pressing plate to move towards the other end of the U-shaped groove of the fixture, and the pressing plate and the side wall at the other end of the U-shaped groove clamp the tail of the air rib.

[0006] Further design of the above technical solution is: the side wall at the other end of the U-shaped groove of the fixture is provided with a boss opposite to the pressing plate, and the tail of the air rib is clamped between the pressing plate and the boss.

[0007] The tail of the air rib is folded, and a core is clamped at the folding part. The core is embedded in the U-shaped groove and is located between the boss and the bottom of the U-shaped groove.

[0008] The tail of the air rib has two folding parts, and a core is clamped at each of the two folding parts. One core is embedded in the U-shaped groove and is located between the boss and the bottom of the U-shaped groove, and the other core is located outside the U-shaped groove.

[0009] The pressing plate is provided with a groove corresponding to the fastening bolt, and one end of the fastening bolt close to the pressing plate abuts against the bottom of the groove.

[0010] On one side where the boss and the pressing plate contact the tail of the air rib, sunken tooth grooves are provided.

[0011] Two limiting bolts are provided at the opening of the U-shaped groove and are arranged on both sides of the air rib.

[0012] The fixture is rotatably connected to the base.

[0013] The plugging structure further includes a connecting piece. The fixture and the connecting piece are provided with mutually matching clamping grooves and clamping blocks. The fixture is connected to the connecting piece through the cooperation of the clamping grooves and the clamping blocks, and the connecting piece is rotatably connected to the base through a rotating shaft.

[0014] The base is provided with a plurality of fixing holes and is fixed to the ground through ground nails arranged in the fixing holes.

[0015] Compared with the prior art, the present invention has the following advantages: In the air rib clamping plate plugging structure of the high-pressure inflatable tent of the present invention, the tail of the air rib is embedded in the U-shaped groove of the fixture, and the pressing plate is pushed by the fastening bolt, so that the pressing plate and the side wall at the other end of the U-shaped groove clamp the tail of the air rib, thereby fixing the air rib. The pressing plate and the side wall of the U-shaped groove are in surface contact with the air rib, and the contact area is large, realizing stable clamping of the air rib on the basis of a simple structure.

[0016] In the present invention, the tail of the air rib is folded and an inner core is arranged at the folding position, so that the inner core is located at the inner bottom of the U-shaped groove. The air rib is restricted by the inner core and is not easy to fall off from the opening of the U-shaped groove. At the same time, the sealing performance is increased and the possibility of air leakage is reduced.

[0017] In the present invention, a sunken tooth groove is provided on one side where the pressing plate contacts the tail of the air rib, increasing the friction between the pressing plate and the air rib and improving the clamping effect.

[0018] In the present invention, two limiting bolts are provided at the opening of the U-shaped groove and are arranged on both sides of the air rib, which can prevent the air rib from falling off from both sides of the U-shaped groove. Description of the Drawings

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Embodiment

[0022] As Figure 1 and Figure 2 shown, the high-pressure inflatable tent air rib splint sealing structure of this embodiment includes a fixture 1, a pressing plate 2, a fastening bolt 3 and a base 6. The fixture 1 is provided with a U-shaped groove 11. The U-shaped groove 11 has two parallel ends. One end of the U-shaped groove 11 is provided with a plurality of screw holes. The fastening bolt 3 is screwed into the screw holes and one end can pass through this end of the U-shaped groove from the outside of the U-shaped groove and extend into the inner side of the U-shaped groove. The pressing plate 2 is arranged in the U-shaped groove 11 of the fixture 1 and one side abuts against the fastening bolt 3. When in use, the tail of the air rib 8 of the high-pressure inflatable tent is embedded in the U-shaped groove 11 and is located between the side wall of the other end of the U-shaped groove 11 away from the fastening bolt 3 and the pressing plate 2. The fastening bolt 3 is screwed, and the fastening bolt 3 pushes the pressing plate 2 to move towards the other end of the U-shaped groove of the fixture, so as to clamp the tail of the air rib 8 by the pressing plate 2 and the side wall of the other end of the U-shaped groove; the fixture 1 is rotatably connected to the base 6, and the base 6 can be fixed on the ground, so as to fix the air rib 8 on the ground.

[0023] In this embodiment, the side wall of the other end of the U-shaped groove 11 is provided with a boss 12 opposite to the pressing plate, and the tail of the air rib is clamped by two planes opposite to the boss 12 by the pressing plate 2, increasing the clamping area.

[0024] When clamping and fixing, the tail of the air rib 8 is folded and an inner core 7 is clamped at the folding place. The inner core can be a thick rope or the like. The inner core 7 is embedded in the U-shaped groove and is located between the boss 12 and the bottom of the U-shaped groove. The pressing plate 2 and the boss 12 clamp the folded air rib 8. Since the thickness at the inner core is greater than that of the folded air rib 8, the inner core 7 can be restricted in the U-shaped groove 11, so that the tail of the air rib 8 is not easily detached from the opening of the U-shaped groove, and the sealing performance is increased, avoiding air leakage of the air rib.

[0025] In this embodiment, the tail of the air rib 8 can also be provided with two folds, and an inner core 7 is clamped at each of the two folds. One inner core 7 is embedded in the U-shaped groove 11 and is located between the boss 12 and the bottom of the U-shaped groove 11, and the other inner core is located outside the U-shaped groove 11, which can further enhance the clamping effect and prevent the air rib 8 from detaching from the opening of the U-shaped groove.

[0026] In this embodiment, the pressing plate 2 is provided with a groove matching the size of the fastening bolt 3 at the position corresponding to the fastening bolt 3. The end of the fastening bolt close to the pressing plate extends into the groove and abuts against the bottom of the groove, which can prevent the pressing plate 2 from shifting when the fastening bolt 3 is tightened.

[0027] In this embodiment, both the boss 12 and the side of the pressing plate 2 in contact with the tail of the air rib 8 are provided with concave tooth grooves, increasing the friction with the air rib and enhancing the clamping effect.

[0028] In this embodiment, through holes are provided on both sides of the air rib 8 corresponding to the opening of the U-shaped groove 11, and limit bolts 9 are arranged in the through holes. Thus, two limit bolts 9 are provided on both sides of the air rib 8 to limit the air rib 8 within the U-shaped groove 11 and prevent the air rib 9 from disengaging from the side of the U-shaped groove 11.

[0029] In this embodiment, the clamp 2 is connected to the base 6 through the connecting member 4. The clamp 1 and the connecting member 4 are respectively provided with a clamping groove and a clamping block that cooperate with each other, so that the clamp 1 is connected to the connecting member 4 through the cooperation of the clamping groove and the clamping block. Then, the connecting member 44 is rotatably connected to the base 6 through a rotating shaft 5. The base 6 is provided with a plurality of fixing holes, and the base 6 can be fixed to the ground through ground nails arranged in the fixing holes. During the inflation molding process of the tent, the connecting member 4 can rotate through the rotating shaft 5 to form a certain angle to cooperate with the tent molding.
