Description

Technical Field

[0001] The utility model 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 skeleton. 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. Utility Model Content

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

[0005] In order to solve the above technical problems, the utility model provides a combined push-pull inflatable tent, which includes a plurality of air ribs that are arched after inflation 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 multiple 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 horizontal and longitudinal air ribs serve as the supporting frame and the inner cavities of the inflatable air ribs are interconnected is changed, if 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 utility model can be quickly deployed or retracted by the sliding of a pulley, and the single air rib in the utility model is also very convenient to transport.

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

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

[0009] As a further improvement of the present invention, the quick tightening mechanism includes a locking block and a lock seat respectively fixed on the side walls of adjacent single-unit slides, the locking block has a locking hook, and the lock seat is hingedly connected to the end of the lever A through a first pin shaft A. The middle part of the lever A is rotatably equipped 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. When the end of the U-shaped locking rod is put on the lock 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 single-unit slide. When the extension line of the two free ends of the U-shaped locking rod intersects with the side wall of the single-unit slide, the two adjacent single-unit slides can be locked.

[0010] Furthermore, the pulley has an upper frame-shaped body, with body 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 body panels on both sides near the two ends of the body. When the pulley is located in the slide, 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 to 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 fastening bolts pass through the clamping blocks on both sides and the bottom of the air rib with the sealing gasket clamped thereon, thereby airtightly securing 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 inward to form sealing edges, and grooves are formed on the opposite outer sides of the two side clamping blocks, and the sealing edges on both sides are precisely located in the corresponding grooves. In the present invention, the sealing edges on both sides can limit the clamping blocks, preventing the clamping blocks on both sides from sliding upward from the upper frame-shaped body.

[0012] The cam is fixed to the upper end of the cam frame, and the cam frame is fixed to the upper end of the cam frame by the cam shaft.

[0013] Furthermore, limit grooves are formed on the side panels of the upper frame-shaped body, away from one end of the pulley locking mechanism, and limit stoppers are rotatably mounted in the limit grooves via limit pins. With this technical feature, when clamping blocks are installed on both sides of the upper frame-shaped body, the limit stoppers can prevent the clamping blocks from sliding out of the end of the body.
