Description

Technical Field

[0001] The present invention relates to the field of inflatable tubes, and particularly to a tent inflatable tube. Background Art

[0002] At present, some outdoor tents are supported by inflatable tubes, such as "A connecting structure between a tent air tube and an air pump" with the Chinese utility model patent publication number CN219158599U, "An inflatable tent" with the Chinese utility model patent publication number CN219491901U, and "Tent" with the Chinese invention patent application publication number CN101608512A. An air inlet / outlet is provided on the inflatable tube. Air is input into the inflatable tube through the air inlet / outlet to make the inflatable tube expand and form, so that the inflatable tube has a certain rigidity, thereby being able to support the tent canvas; when the tent needs to be stored, the air in the inflatable tube is discharged through the air inlet / outlet, and the inflatable tube can be flattened and folded (or rolled) up. During the air exhaust process, due to the relatively large length of the inflatable tube, when the inflatable tube partially collapses, the inner walls of the inflatable tube are close to each other, resulting in the air in the inflatable tube not being easily emptied. Even if the air in the inflatable tube is squeezed out by hand, the resistance during air discharge is relatively large, and poor air exhaust is likely to cause air reflux. Therefore, the effect of squeezing out air by hand is also not good, resulting in poor air evacuation effect in the air tube, and more air pockets are formed after the inflatable tube is stored, which is not conducive to storing the inflatable tube in a smaller volume. Therefore, it is necessary to improve the existing inflatable tube. Summary of the Invention

Detailed implementation manners

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] The tent inflatable tube of the present invention, as Figure 1 and Figure 2 shown, includes an inflatable tube body 1, and an inflation / deflation port 12 is provided on the inflatable tube body 1. For example, a ventilation tube is welded to the inflatable tube body 1, and a sealing cover is screwed to the ventilation tube, and the inflation / deflation port 12 is formed in the above-mentioned ventilation tube. The inflatable tube body 1 can be made of polyvinyl chloride. As Figure 1 and Figure 2 shown, an exhaust support member 2 is provided inside the inflatable tube body 1, and the exhaust support member 2 is arranged along the inflatable tube body 1. In other words, the exhaust support member 2 extends from one end of the inflatable tube body 1 to the corresponding other end of the inflatable tube body 1.

[0030] When it is necessary to store the tent inflatable tube of the present invention, open the inflation / deflation port 12. At the beginning, since the air pressure inside the inflatable tube body 1 is relatively high, the air is quickly exhausted through the inflation / deflation port 12, and then the inflatable tube body 1 is folded or wound by hand. During this period, the outer wall of the inflatable tube body 1 can be pushed with the hand to expel the air inside the inflatable tube body 1 to the inflation / deflation port 12; in this process, as Figure 2 and Figure 5 shown, the inflatable tube body 1 deflates and turns into a flattened state, so the inflatable tube body 1 turns into a form in which the first film layer 101 and the second film layer 102 overlap. Since the exhaust support member 2 is provided inside the inflatable tube body 1, as Figure 2As shown, the first film layer 101 is attached to the left side of the exhaust support member 2, and the second film layer 102 is attached to the right side of the exhaust support member 2. Thus, the exhaust support member 2 separates the first film layer 101 from the second film layer 101, as Figure 5 shown. Since the first film layer 101 and the second film layer 102 are separated at the left and right sides of the exhaust support member 2, the first film layer 101 and the second film layer 102 form an exhaust passage 100 under the action of the exhaust support member 2. Therefore, the air in the inflatable tube body 1 can flow along the exhaust passage 100. That is to say, the function of the exhaust support member 2 is to support the inflatable tube body 1 from the inside to form the exhaust passage 100. By providing the exhaust support member 2, within the length range of the inflatable tube body 1, the effect of the complete adhesion of the first film layer 101 and the second film layer 102 is eliminated, which is beneficial to the discharge of the air in the inflatable tube body 1, and thus beneficial to the inflatable tube being able to be stored in a smaller volume.

[0031] Preferably, the exhaust support member 2 is continuously extended along the inflatable tube body 1, which is beneficial to the exhaust passage 100 being able to be continuously connected to the flattened inflatable tube body 1, and the resistance suffered by the air discharge in the inflatable tube body 1 is smaller.

[0032] Preferably, the exhaust support member 2 is movably arranged relative to the inner wall of the inflatable tube body 1, which can reduce the influence of the exhaust support member 2 on the expansion and bending of the inflatable tube body 1, and also avoid the cost increase caused by the need to add a continuous connection structure between the exhaust support member 2 and the inner wall of the inflatable tube body 1. In some embodiments, the exhaust support member 2 can also be positioned on the inner wall of the inflatable tube body 1. When the inflatable tube body 1 is stored, the position of the exhaust support member 2 is relatively stable, which is beneficial to the relatively regular shape of the tent inflatable tube during storage.

[0033] Furthermore, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, sealing portions 11 are respectively provided at both ends of the inflatable tube body 1. That is to say, the ultrasonic welding process can be used to press and seal both ends of the inflatable tube body 1. Both ends of the exhaust support member 2 are respectively connected to the corresponding sealing portions 11, thereby preventing the exhaust support member 2 from curling to one end of the inflatable tube body 1, which is beneficial to the exhaust support member 2 maintaining the shape of extending along the inflatable tube body 1.

[0034] Embodiment 1, as Figure 1 and Figure 2As shown, one end of the hanging ring 4 is clamped by the sealing part 11, and the sealing part 11 is welded to the hanging ring 4. That is to say, the sealing part 11 is connected with the hanging ring 4. Both ends of the exhaust support 2 are respectively provided with rope loops 3, and the hanging ring 4 is connected with the rope loops 3. Specifically, the hanging ring 4 can be made of a plastic film (for example, polyvinyl chloride can be used). First, the plastic film used to form the hanging ring 4 is folded. The open end of the hanging ring 4 is inserted between the first film layer 101 and the second film layer 102, and the open end of the hanging ring 4 passes through the sealing part 11 and extends to the outside of the air charging pipe body 1. Then, the hanging ring 4 is fixed on one end of the sealing part 11 through an ultrasonic welding process to form a sealed state. The other end of the hanging ring 4 is connected with the rope loop 3. Specifically, one end of the rope loop 3 passes through the hanging ring 4 and is fixed on the hanging ring 4. The corresponding other end of the rope loop 3 is welded or bonded to the end of the exhaust support 2. For example, the end of the exhaust support 2 is formed with a cylindrical end 202. The corresponding other end of the above-mentioned rope loop 3 is a knotted end, and the above-mentioned cylindrical end 202 is heat-melted to cover the knotted end of the rope loop 3, so as to prevent the rope loop 3 from loosening from the exhaust support 2. Since the exhaust support 2 is connected with the hanging ring 4 through the rope loops 3 at both ends, the exhaust support 2 can move left and right or up and down in the air charging pipe body 1.

[0035] Embodiment 2, as Figure 3 and Figure 4 shown, is basically the same as Embodiment 1. The difference is that both ends of the exhaust support 2 are respectively provided with rope loops 3. One end of the rope loop 3 passes through the sealing part 11 and extends to the outside of the air charging pipe body 1, and the rope loop 3 is fixed on one end of the sealing part 11 through an ultrasonic welding process to form a sealed state. Similarly, the corresponding other end of the rope loop 3 is welded or bonded to the end of the exhaust support 2, that is, the end of the exhaust support 2 is formed with a cylindrical end 202. The corresponding other end of the above-mentioned rope loop 3 is a knotted end, and the above-mentioned cylindrical end 202 is heat-melted to cover the knotted end of the rope loop 3, so as to prevent the rope loop 3 from loosening from the exhaust support 2.

[0036] Embodiment 3, as Figure 1 、 Figure 3 and Figure 6As shown, the exhaust support member 2 includes a helical spring wire 20. Rope loops 3 are respectively provided at both ends of the helical spring wire 20. On the basis of the understanding of Embodiment 1 or Embodiment 2, the rope loop 3 of the exhaust support member 2 is hermetically connected to the sealing portion 11 through a hanging loop 4 or the rope loop 3 is directly hermetically connected to the sealing portion 11; the helical spring wire 20 is arranged in a whole section. That is to say, the helical spring wire 20 is helically wound to form a spring structure. Thus, an air passage is formed inside the spring structure, and an air vent gap is formed between adjacent turns of the helical spring wire 20. Thus, the air in the inflatable tube body 1 can flow into or out of the above air passage through the above air vent gap, which is further beneficial to the evacuation of the air in the inflatable tube body 1; due to the good elastic telescopic effect of the helical spring wire 20, when the inflatable tube body 1 is inflated and expanded, the exhaust support member 2 can be stretched correspondingly well, avoiding the exhaust support member 2 from being torn off and also avoiding the exhaust support member 2 from interfering with the inflation and expansion of the inflatable tube body 1. That is to say, when inflating, high-pressure gas enters the inflatable tube body 1 from the air inlet / outlet 12. Due to the elasticity of the helical spring wire 20, under the action of the high-pressure gas, the helical spring wire 20 swings inside the inflatable tube body 1. Through the swinging action inside the inflatable tube body 1, the first film layer 101 and the second film layer 102 are further separated, and the corresponding parts of the positions where the first film layer 101 and the second film layer 102 were originally in a fitting state are supported and separated. That is, the corresponding flattened part of the inflatable tube body 1 is supported and separated by the helical spring wire 20, effectively solving the problem of being hindered during inflation due to the fitting of the first film layer 101 and the second film layer 102, thereby preventing the inflatable tube body 1 from being inflated and formed. The helical spring wire 20 can be made of a material with good softness, such as polyvinyl chloride, polypropylene or low-density polyethylene, etc., which is beneficial to the flexible bending of the helical spring wire 20 when the tent inflatable tube is stored and further avoids the exhaust support member 2 from interfering with the inflation and expansion of the inflatable tube body 1.

[0037] In some embodiments, as Figure 6 shown, the helical spring wire 20 is arranged in sections, and adjacent helical spring wires 20 are connected by a joint 201. For example, the joint 201 includes two mutually buckled ring members, and the above two ring members are respectively connected (which can be welded or bonded) to adjacent helical spring wires 20. Through the above arrangement, the total length of the exhaust support member 2 can be changed by increasing or decreasing the number of sections of the helical spring wire 20, and the length specification of the inflatable tube body 1 can be correspondingly matched, which is beneficial to the flexible production of the tent inflatable tube.

[0038] Embodiment 4, as Figure 7As shown, the exhaust support member 2 includes a flexible support strip 21, and the flexible support strip 21 can be made of materials with good flexibility such as polyvinyl chloride, polypropylene, or low-density polyethylene. Beads 22 are provided on the flexible support strip 21. The beads 22 can be welded to the flexible support strip 21 or integrally formed with the flexible support strip 21. For this embodiment, the beads 22 are distributed on the flexible support strip 21 at equal intervals; specifically, since the beads 22 contact and support the second film layer 102 and the first film layer 101, the inner wall of the air charging tube body 1 is in a separated state. Thus, an air ventilation gap 5 is formed at the outer peripheral part of the flexible support strip 21 between adjacent beads 22. Further, one side of the bead 22 contacts the first film layer 101, and the other side of the bead 22 contacts the second film layer 102, resulting in the non-adhesion of the first film layer 101 and the second film layer 102 at the positions near the left and right sides of the bead 22. Under the action of discharging air, there is a gap at the position near the first film layer 101 where one side (left side) of the bead 22 contacts. Similarly, there is a gap at the position near the second film layer 102 where the other side (right side) of the bead 22 contacts. Thus, the air in the air charging tube body 1 can pass through the voids at the positions near the left and right sides of the bead 22 and then flow to the above-mentioned air ventilation gap 5. That is to say, when the air charging tube body 1 discharges air, the air in the air charging tube body 1 can pass through the air ventilation gap 5 and then flow. In other words, the voids at the positions near the left and right sides of the bead 22 and the above-mentioned air ventilation gap 5 combine to form an exhaust passage 100, which is beneficial for the tent air charging tube to be easily emptied.

[0039] In this embodiment, both ends of the flexible support strip 21 are welded to the sealing part 11. The specific fixing method is similar to that of the second embodiment, that is, one end of the flexible support strip 21 passes through the sealing part 11 and extends to the outside of the air charging tube body 1, and one end of the flexible support strip 21 is fixed to one end of the sealing part 11 by ultrasonic welding technology to form a sealed state; similarly, the other end of the flexible support strip 21 also passes through the other sealing part 11 and extends to the outside of the air charging tube body 1, and the other end of the flexible support strip 21 is fixed to the other sealing part 11 by ultrasonic welding technology to form a sealed state.

[0040] For those skilled in the art, such as Figure 9As shown, the bead 22 can be installed on the flexible support bar 21 by an active connection method. For this embodiment, the flexible support bar 21 is cylindrical. The bead 22 is provided with a through hole 6 adapted to the outer diameter of the flexible support bar 21. It should be noted that the diameter of the through hole 6 of the bead 22 is larger than the outer diameter of the flexible support bar 21, and the diameter of the through hole 6 is only slightly larger than the outer diameter of the flexible support bar 21, so that the bead 22 can move on the flexible support bar 21 without obstruction. Such a design facilitates the flexible installation of the bead 22 on the flexible support bar 21, thus facilitating the back-and-forth movement of the bead 22 on the flexible support bar 21. When actually discharging the air in the inflatable tube body 1, it is possible that the first film layer 101 and the second film layer 102 are adhered due to special reasons, so that the air in the inflatable tube body 1 cannot be effectively discharged. Since the bead 22 moves back and forth on the flexible support bar 21, the user can move the bead 22 to the adhered position of the inflatable tube body 1, so as to separate the corresponding first film layer 101 and the second film layer 102 at the adhered position, thus solving the technical problem that the air cannot be discharged due to the adhesion of the first film layer 101 and the second film layer 102.

[0041] Embodiment Five, as Figure 8 shown, the exhaust support member 2 includes a support rope 23, and knotting portions 231 are distributed on the support rope 23. That is to say, the support rope 23 is knotted at intervals first, and then the support rope 23 is placed into the inflatable tube body 1. The two ends of the support rope 23 can be respectively buckled and connected to the corresponding hanging rings 4 or directly penetrate through the sealing portion 11 and extend to the outside of the inflatable tube body 1, and the two ends of the support rope 23 are respectively fixed to both ends of the sealing portion 11 by an ultrasonic welding process to form a sealed state; the first film layer 101 and the second film layer 102 are relatively supported by the knotting portions 231, so that the inner wall of the inflatable tube body 1 is in a separated state. When the tent inflatable tube is stored, an exhaust channel 100 can be formed, which is beneficial to the easy emptying of the inflatable tube body 1. The knotting portions 231 can be equally spaced or non-equally spaced.

[0042] Embodiment Six, as Figure 10As shown, the exhaust support member 2 includes a microcellular foam strip 24. The material of the microcellular foam strip 24 belongs to the prior art. For example, reference can be made to the "Open-cell Polypropylene Microcellular Foam Sheet and Its Production Method" with the Chinese invention patent publication number CN104629176B. Due to the foaming structure of the microcellular foam strip 24, the density of the microcellular foam strip 24 is relatively low, which is beneficial to reducing the weight of the tent inflatable tube. Moreover, since the surface of the microcellular foam strip 24 has fine pits, when the inner wall of the inflatable tube body 1 abuts against the microcellular foam strip 24, the airtightness is poor, and air can pass between the microcellular foam strip 24 and the inner wall of the inflatable tube body 1. For example, both ends of the microcellular foam strip 24 can be connected to rope loops 3. The rope loops 3 are respectively threaded and connected to the corresponding hanging loops 4 or directly pass through the sealing part 11 and extend to the outside of the inflatable tube body 1, and the two ends of the rope loops 3 are respectively fixed corresponding to both ends of the sealing part 11 through an ultrasonic welding process to form a sealed state.

[0043] As Figure 11 shown, for example, two tent inflatable tubes of the present invention can be cross-connected to form a support structure for supporting the tent tarpaulin. Specifically, an air pump is connected through the air inlet / outlet 12 provided on the inflatable tube body 1, and the air pump is used to inflate the inflatable tube body 1, thereby forming a support structure for supporting the tent tarpaulin.
