Description

Technical Field

[0001] The present invention relates to the technical field related to hot air balloons, and in particular to an inflation auxiliary device for hot air balloons. Background Art

[0002] A hot air balloon is a lighter-than-air craft with a large balloon-like upper part and a basket at the lower part. The heated air inside the balloon, which has a lower density than the cold air outside, acts as buoyancy to move the whole; the basket can carry passengers and a heat source. Modern sport balloons are usually made of nylon fabric with refractory openings.

[0003] A hot air balloon is mainly composed of a huge balloon and a basket for carrying people or goods, a burner for heating the air, and several connecting ropes for connecting the basket and the balloon.

[0004] When inflating a hot air balloon, the basket tilts over, and two people are needed to hold open the opening of the balloon, while one person operates the burner. At the same time, care must be taken that the flame does not burn the connecting rope. During the initial inflation, a point spray method is required to inflate the balloon to avoid the high temperature causing the person holding the balloon opening to be unable to withstand it. During ignition, the flame is close to the edge of the connecting rope and the opening end of the balloon to avoid the flame burning the connecting rope and the balloon. Therefore, the point spray method is inefficient and time-consuming to ignite and inflate, so it is necessary to design an inflation auxiliary device for the hot air balloon.

[0033] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0034] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0035] like Figure 1-10 As shown, an inflation auxiliary device for a hot air balloon comprises: a plurality of support frames 1 which are arranged in a straight line in sequence and have increasing specifications and can be stacked together, two adjacent support frames 1 are connected by at least one X-shaped deformation frame 2, one of the side edges of the support frame 1 is the bottom edge, and the other side edges of the support frame 1 are provided with extension units, and the extension units include support arms 3 which are arranged parallel to the corresponding side edges of the support frame 1 and can move away from the side edges of the support frame 1.

[0036] In the above technical solution, when inflating the hot air balloon, the auxiliary equipment is placed between the hanging basket and the balloon, and then several support frames 1 are unfolded. The distance between two adjacent support frames 1 is increased, and the support frame 1 will separate several connecting ropes and can also open the open end of the balloon. The flame after the burner is ignited can pass through the several support frames 1 and enter the balloon, so that after the hot air enters the balloon, it can not only prevent the connecting rope from being burned, but also open the open end of the balloon. There is no need to manually open the open end of the balloon, and the ignition time of the point-spraying inflation flame can be extended, thereby improving the inflation efficiency. The auxiliary device is small in size after folding, which is convenient for carrying.

[0037] The bottom side of the support frame 1 is in contact with the ground. By using an extension unit, the distance between the support arm 3 and the support frame 1 is increased, which can further expand the opening of the balloon and also increase the distance between the connecting rope and the flame.

[0038] In a preferred embodiment of the invention, the X-shaped deformation frame 2 includes a pair of first connecting rods hinged at the middle part by a first hinge axis, and the support frame 1 is penetrated with a first mounting through hole and a first strip through groove 4 matching the X-shaped deformation frame 2, one end of the first connecting rod is hinged to the first mounting through hole on the corresponding support frame 1 through a first hinge bolt, and the other end of the first connecting rod is hinged to a second hinge bolt that passes through the first strip through groove 4 on the adjacent support frame 1 and is hinged to the end of the first connecting rod in another X-shaped deformation frame 2.

[0039] In the above technical solution, two adjacent X-shaped deformation frames 2 share a second hinge bolt, and when one X-shaped deformation frame 2 is extended, it can drive several X-shaped deformation frames 2 to be extended at the same time, thereby improving the convenience of use.

[0040] In a preferred embodiment of the invention, a first hinged portion 5 is provided on the side of the support frame 1 in the same length direction and hinged to the extension unit, and the extension unit also includes a connecting arm 7 parallel to the support arm 3 and hinged to the first hinged portion 5 through a third hinge bolt 6, a telescopic mechanism for connecting the support arm 3 and the connecting arm 7, a clamping mechanism mounted on the support arm 3 for fixing the telescopic mechanism, and a positioning mechanism mounted on the connecting arm 7 for positioning the connecting arm 7 after rotation.

[0041] In the above technical solution, the connecting arm 7 is hinged to the first hinge shaft through the third hinge bolt 6, which is convenient for adjusting the position of the extension unit when storing and unfolding. After the telescopic mechanism is unfolded, the distance between the connecting arm 7 and the support arm 3 increases, and then the unfolded state of the telescopic mechanism is locked by the clamping mechanism.

[0042] In a preferred embodiment of the invention, a pair of second hinged portions 8 are protruded from the connecting arm 7 and are respectively located on both sides of the first hinged portion 5 and are both hinged to the third hinged bolt 6;

[0043] The positioning mechanism includes a sliding sleeve 9 slidably mounted on the third hinge bolt 6 and located between the first hinge part 5 and the second hinge part 8, and a spring 10 mounted on the third hinge bolt 6. The sliding sleeve 9 is fixedly connected to a guide rod 11 that is slidably inserted into the second hinge part 8 along the axial direction of the third hinge bolt 6. The two ends of the spring 10 respectively contact the sliding sleeve 9 and the second hinge part 8. The end of the first hinge part 5 opposite to the sliding sleeve 9 is recessed with at least two positioning grooves 12 arranged at intervals in the circumferential direction of the third hinge bolt 6. The end surface of the sliding sleeve 9 close to the first hinge part 5 is protruding with a hemispherical positioning part 13 that can be inserted into the corresponding positioning groove 12.

[0044] In the above technical solution, the shape of the hemispherical positioning portion 13 is set so that it can slide out of the positioning groove 12. When the connecting arm 7 is rotated, the hemispherical positioning portion 13 will be squeezed to slide out of the corresponding positioning groove 12. As the connecting arm 7 rotates, the hemispherical positioning portion 13 will be inserted into the corresponding positioning groove 12.

[0045] In a preferred embodiment of the invention, the telescopic mechanism includes a pair of second connecting rods 14 hinged at the middle part by a second hinge axis, and the support arm 3 and the connecting arm 7 are both provided with a second mounting through hole and a second strip through groove 15 in the same length direction. One end of the second connecting rod 14 is installed on the corresponding second mounting through hole through a fourth hinge bolt, and the other end of the second connecting rod 14 is hinged with a fifth hinge bolt 16 that slides through the corresponding second strip through groove 15.

[0046] In a preferred embodiment of the invention, the clamping mechanism includes a clamping arm 17 assembled on the support arm 3 through a sixth hinge bolt, and a torsion spring 18 assembled on the sixth hinge bolt for pushing the clamping arm 17 to rotate close to the second strip through slot 15, the sixth hinge bolt is located on the side of the second strip through slot 15 close to the second mounting through hole, the clamping arm 17 is protruded with a limiting portion 19 that can abut against the support arm 3, and the end of the clamping arm 17 away from the sixth hinge bolt is protruded with an inclined wedge portion 20 for clamping the corresponding fifth hinge bolt 16.

[0047] In the above technical solution, after the telescopic mechanism is unfolded, the fifth hinge bolt 16 located on the support arm 3 will move to the end of the second strip through slot 15 close to the second mounting through hole, and the second hinge bolt will pass over the inclined wedge portion 20. At this time, the inclined wedge portion 20 will restrict the fifth hinge bolt 16 to the end of the second strip through slot 15 and cannot move, thereby locking the telescopic mechanism in the extended state.

[0048] When the telescopic mechanism needs to be folded, the clamping arm 17 is moved away from the second strip through slot 15 so that the inclined wedge portion 20 is misaligned with the second strip through slot 15 , and the fifth hinge bolt 16 can slide in the second strip through slot 15 .

[0049] In a preferred embodiment of the invention, a handle portion 21 is provided on the support arm 3 .

[0050] In a preferred embodiment of the invention, a pull ring portion 22 is provided on the clamp arm 17 .

However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.
