Description

Technical Field

[0001] The invention relates to an inflatable tent, in particular to a combined push-pull inflatable tent. Background Art

[0002] At present, most of the medium and large inflatable tents produced at home and abroad are of one-piece structure, with horizontal and vertical air ribs as the supporting frame. The inner cavities of the inflatable air ribs are interconnected and the outer layer is covered with tarpaulin.

[0003] The above-mentioned integrated medium and large inflatable tents have the following main disadvantages: First, due to the integrated structure, the inner cavities of the air ribs are interconnected. If a single air rib is damaged and leaks, all the air ribs will lose pressure, causing the entire tent to collapse; Second, medium and large tents are heavy and large in size, so they are difficult to unfold, fold and transport. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a combined push-pull inflatable tent, which is relatively easy to unfold, fold and transport. When a single air rib is damaged and leaks, other air ribs will not lose pressure, and the entire tent will not collapse.

[0005] In order to solve the above technical problems, the combined push-pull inflatable tent of the present invention includes a plurality of air ribs that are arched after being inflated and a tarpaulin that can overlap and cover the plurality of arched air ribs. It also includes slides arranged on both sides of the air ribs and a plurality of pulleys that can slide in the slides on both sides. The bottom air seals on both sides of each arched air rib are fixed to the corresponding pulleys on both sides, and each pulley is provided with a pulley locking mechanism that can lock the pulley on the slide.

[0006] The combined push-pull inflatable tent adopts the above structure. Since the traditional structure in which the horizontal and vertical air ribs are used as the supporting frame and the inner cavities of the inflatable air ribs are interconnected is changed, when a single air rib is damaged and leaks, the other air ribs will not lose pressure and will not cause the entire tent to collapse. The present invention can be quickly deployed or retracted by the sliding of a pulley, and the single air rib in the present invention is also very convenient to transport.

[0007] As an improvement of the present invention, the slideway is composed of multiple sections of single slideways plugged into each other, and adjacent single slideways are locked and fixed by a quick locking mechanism. After adopting the above structure, the slideway can be split into multiple sections of single slideways, making the transportation of the present invention more convenient.

[0008] Furthermore, the cross section of the single slide is rectangular, and the rectangular single slide has side walls, a top wall and a bottom wall on both sides, and an opening for the slideway to slide through is provided along the length direction of the top wall, and one end of the side wall has a protruding side wall trapezoidal plug-in plate, and the other end has a side wall trapezoidal plug-in port corresponding to the side wall trapezoidal plug-in plate, and one end of the bottom wall has a protruding bottom wall trapezoidal plug-in plate, and the other end has a bottom wall trapezoidal plug-in port corresponding to the bottom wall trapezoidal plug-in plate. After adopting the above technical features, when adjacent single slides are plugged into each other, the side wall trapezoidal plug-in plate of one single slide can be plugged into the side wall trapezoidal plug-in port of another single slide, and the bottom wall trapezoidal plug-in plate of one single slide can be plugged into the bottom wall trapezoidal plug-in port of another single slide.

[0009] As a further improvement of the present invention, the quick-tightening mechanism includes a locking block and a locking seat respectively fixed on the side walls of adjacent monomer slides, the locking block is provided with a locking hook, and the lock seat is hingedly connected to the end of the lever handle A through a first pin shaft A, and the middle part of the lever handle A is rotatably provided with a second pin shaft A, and also includes a U-shaped locking rod, the two ends of the second pin shaft A are fixedly connected to the two free ends of the U-shaped locking rod, and when the end of the U-shaped locking rod is sleeved on the locking hook of the locking block and the handle A is pressed, the second pin shaft A can drive the two free ends of the U-shaped locking rod to approach the side wall of the monomer slide, and when the extension lines of the two free ends of the U-shaped locking rod intersect with the side walls of the monomer slide, the two adjacent monomer slides can be locked.

[0010] Furthermore, the pulley has an upper frame-shaped body with wall panels on both sides of the bottom of the body, and upper and lower guide walking wheels and left and right guide wheels are symmetrically installed on the wall panels on both sides near the two ends of the body. When the pulley is located in the slideway, the upper and lower guide wheels can prevent the pulley from moving up and down, and the left and right guide wheels can prevent the pulley from sliding left and right.

[0011] As another improvement of the present invention, the upper frame-shaped body is provided with clamping blocks on both sides, the bottom of the air rib is clamped with a sealing gasket, and the fastening bolts pass through the clamping blocks on both sides and the bottom of the air rib clamped with the sealing gasket to airtightly fix the bottom of the air rib between the clamping blocks on both sides; the tops of the two side wall panels of the upper frame-shaped body are folded to the opposite inner sides to form edge sealing, and the opposite outer sides of the two side clamping blocks are correspondingly formed with grooves, and the edge sealing on both sides is just located in the corresponding grooves. In the present invention, the edge sealing on both sides can limit the clamping blocks to prevent the clamping blocks on both sides from sliding upward from the upper frame-shaped body.

[0012] As another improvement of the present invention, the pulley locking mechanism includes a mounting plate fixed at one end of the pulley, an arched mounting support is fixed on the outer side of the mounting plate, and also includes a lever B. The lever B includes an upper rotating rod, and the lower end of the rotating rod is connected to a lever. The upper end of the rotating rod of the lever B is hingedly connected to the upper part of the mounting support through a first pin shaft B, and the lower end of the rotating rod is hingedly connected to a connecting rod through a second pin shaft B. A sliding cavity is formed at the lower part of the mounting support, and a matching sliding rod passes through the sliding cavity from bottom to top, and the top end of the sliding rod is hingedly connected to the bottom end of the connecting rod through a third pin shaft B. The bottom of the sliding rod has a tightening block. When the lever of the lever B is pressed down, the connecting rod can make the sliding rod slide downward in the sliding cavity. When the center line of the rotating rod deviates from the axis of the sliding rod and obliquely toward the mounting plate, the lower part of the rotating rod can abut against the inner upper part of the bow back. At this time, the tightening block can tighten the bottom wall of the slide, thereby locking the pulley on the slide.

[0013] Furthermore, the side wall plates of the upper frame-shaped vehicle body away from one end of the pulley locking mechanism are provided with limit grooves, and the limit baffles are rotatably installed in the limit grooves through the limit pins. With the above technical features, when the upper frame-shaped vehicle body is provided with clamping blocks located on both sides, the limit baffles can prevent the clamping blocks on both sides from sliding out from the ends of the vehicle body.
