Description

Technical Field

[0001] The present invention relates to a high-pressure inflatable tent air rib clamp structure, 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, there is a problem of fixing the tail of the air rib. The existing fixture structures for fixing the tail of the air rib are relatively complex and prone to problems such as the fixture loosening and slipping.

[0003] For example, a high-pressure air rib fixing tooling disclosed in Patent CN202320993104.1 includes a frame and two clamping plates. A first support is provided on the frame, and second supports for cooperating with the first support are provided on both clamping plates. The first support on the frame and the second supports on both clamping plates are detachably connected by fixing pins. The connection between the two clamping plates is detachable. After the two clamping plates are assembled, a cavity for accommodating the air rib column foot is formed in the middle. The end faces between the two clamping plates clamp the air rib column foot. The structure of this tooling is relatively complex and only clamps the air rib by the clamping plates, resulting in a poor fixing effect on the air rib and a risk of falling off and air leakage. Summary of the Invention

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

[0005] To achieve the above object, the technical solution proposed by the present invention is: a high-pressure inflatable tent air rib clamp structure, including a first clamping plate, a second clamping plate, a support, and a fastening bolt. The middle parts of the first clamping plate and the second clamping plate are hinged to each other through a rotating shaft, and the rotating shaft is arranged on the support. A plurality of screw holes are provided at one end of the first clamping plate, and a fastening bolt is screwed into the screw holes; by turning the fastening bolt, the fastening bolt moves towards the side close to the second clamping plate, and the second clamping plate is pushed so that the first clamping plate and the second clamping plate are separated from each other at the end corresponding to the fastening bolt, then the other ends of the first clamping plate and the second clamping plate are close to each other to clamp the tail end of the high-pressure inflatable tent air rib.

[0006] Further design of the above technical solution is: grooves are provided on the opposite surfaces of the first clamping plate and the second clamping plate at the end far from the fastening bolt. The tail end of the high-pressure inflatable tent air rib is folded and clamps an inner core, and the inner core is embedded in the groove.

[0007] A plurality of concave tooth grooves are provided on the opposite surfaces of the first clamping plate and the second clamping plate at the end far from the fastening bolt, and the tooth grooves are arranged between the groove and the ends of the first clamping plate and the second clamping plate.

[0008] Two limit bolts are provided on the first clamping plate and the second clamping plate corresponding to one end of the high-pressure inflatable tent air rib, and are arranged on both sides of the high-pressure inflatable tent air rib.

[0009] Both ends of the rotating shaft extend out of the first clamping plate and the second clamping plate, and both ends are rotatably connected to the support.

[0010] The support includes a base and two brackets fixed on the base. Connection holes are provided on the brackets, and both ends of the rotating shaft are connected to the two connection holes.

[0011] Both ends of the rotating shaft are rotatably connected to the support through bearings.

[0012] Side ears are provided around the base, and fixing holes are provided on the side ears. The base is fixed to the ground by ground nails arranged in the fixing holes.

[0013] Compared with the prior art, the present invention has the following advantages: In the air rib clamp structure of the high-pressure inflatable tent of the present invention, through two hinged clamping plates, the tail end of the air rib is clamped at one end of the two clamping plates, and the other ends of the two clamping plates are pushed outwards by bolts, so that one ends of the two clamping plates clamping the tail end of the air rib approach each other, clamping the tail end of the air rib firmly and stably.

[0014] In the present invention, grooves are provided at one ends of the two clamping plates that clamp the tail end of the air rib, and the tail end of the air rib is folded and clamped with an inner core and then clamped by the two clamping plates. The inner core is placed in the groove. The air rib is restricted by the inner core and is not easy to loosen and slide off, and the sealing performance is increased, further reducing the possibility of air leakage. Thus, on the basis of a simple structure, the air rib is clamped firmly and stably in the present invention.

[0015] In the present invention, concave tooth grooves are provided on the contact surfaces of the two clamping plates and the air rib, increasing the friction between the clamping plates and the air rib and improving the clamping effect.

[0016] In the present invention, two limiting bolts are provided on the two clamping plates 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

[0017] Figure 1 is an overall structure diagram of the air rib clamp structure of the high-pressure inflatable tent of the present invention; Figure 2 is a sectional view of the air rib clamp structure of the high-pressure inflatable tent.

[0018] In the figure: 1 - first clamping plate, 11 - groove, 12 - tooth groove, 2 - second clamping plate, 3 - rotating shaft, 4 - tightening bolt, 5 - support, 51 - base, 52 - bracket, 53 - side ear, 6 - air rib, 7 - inner core, 8 - limiting bolt. Detailed Embodiment

[0019] The present invention will be described in detail below in conjunction with the drawings and specific embodiments. Embodiment

[0020] As Figure 1 AndFigure 2 As shown in the figure, the high-pressure inflatable tent air rib fixture structure of this embodiment includes a first clamping plate 1 and a second clamping plate 2. The middle parts of the first clamping plate 1 and the second clamping plate 2 are hinged by a rotating shaft 3, so that the two ends of the first clamping plate 1 and the second clamping plate 2 move in opposite directions.

[0021] Both ends of the rotating shaft 3 extend out of the first clamping plate 1 and the second clamping plate 2, and the two ends of the rotating shaft 3 are arranged on the support 5.

[0022] A number of screw holes are provided at one end of the first clamping plate 1, and a fastening bolt 4 is screwed into the screw holes; turning the fastening bolt 4 can make the fastening bolt 4 move towards the side close to the second clamping plate 2 and push the second clamping plate 2; in this embodiment, the tail end of the air rib 6 is clamped at one end of the first clamping plate 1 and the second clamping plate 2 away from the fastening bolt 4, and then the fastening bolt 4 is turned to make the fastening bolt 4 push the second clamping plate 2. The ends of the first clamping plate 1 and the second clamping plate 2 corresponding to the fastening bolt move away from each other, and the other ends of the first clamping plate 1 and the second clamping plate 2 move closer to each other, so as to clamp the tail end of the high-pressure inflatable tent air rib.

[0023] In this embodiment, the opposite surfaces of the first clamping plate 1 and the second clamping plate 2 at the end away from the fastening bolt 4 are both provided with grooves 11, and the positions of the two grooves 11 correspond to each other. When clamping the air rib 6 of the high-pressure inflatable tent, the tail end of the air rib 6 is folded and bypassed around an inner core 7, such as a rope, etc., so that the folded tail end of the air rib 6 clamps the inner core 7, and the inner core is embedded in the groove 11. The first clamping plate 1 and the second clamping plate 2 clamp the folded air rib 6. Since the thickness at the inner core is greater than that of the folded air rib 6, the inner core is restricted in the groove 11, making the clamping more firm and not easy to fall off and leak air.

[0024] In this embodiment, the opposite surfaces of the first clamping plate 1 and the second clamping plate 2 at the end away from the fastening bolt 4 are provided with a number of concave tooth grooves 12. The tooth grooves 12 are arranged between the groove 11 and the ends of the first clamping plate 1 and the second clamping plate 2. Thus, when clamping the air rib 6, the tooth grooves 12 can abut against the tail end of the folded air rib 6, increasing the friction between the air rib and the fixture and further enhancing the clamping effect.

[0025] In this embodiment, through holes corresponding to each other are respectively provided on both sides of the first clamping plate 1 and the second clamping plate 2 corresponding to one end of the air rib 6. A limit bolt 8 and a corresponding nut are provided in the through holes. The limit bolt 8 is passed through the two through holes on the first clamping plate 1 and the second clamping plate 2 and fixed by the nut. The two limit bolts 8 are arranged on both sides of the high-pressure inflatable tent air rib 6, restricting the air rib 6 inside and preventing the air rib 6 from slipping out from both sides of the two clamping plates.

[0026] In this embodiment, the support 5 includes a base 51 and two brackets 52 fixed on the base 51. The two brackets 52 are arranged at both ends of the first clamping plate 1 and the second clamping plate 2. Connecting holes are provided on the brackets 52, and both ends of the rotating shaft 3 are connected to the two connecting holes. In this embodiment, both ends of the rotating shaft 3 can be fixedly connected to the support 3, or can be rotatably connected to the support 5 through bearings. During the inflation molding process of the tent, the two clamping plates can rotate relative to the base 51 to form an angle, cooperating with the tent molding.

[0027] Side ears 53 are provided around the base 51, and fixing holes are provided on the side ears 53. During use, after clamping the air rib 6, the support 5 is fixed to the ground by setting ground nails in the fixing holes.

[0028] The technical solution of the present invention is not limited to the above embodiments, and all technical solutions obtained by means of equivalent replacement fall within the scope of protection required by the present invention.
