A hinged and foldable tent without assembly

technical field

The invention relates to a new type of tent composed of a support frame and a tent cloth, wherein the support frame is composed of a diamond-shaped four-bar linkage mechanism, a four-bar linkage mechanism of equal length, a four-bar linkage mechanism of unequal length, and a cable, and the folding and unfolding is simple and easy to operate , and portable, stable.

Background technique

More and more people like outdoor activities, whether it is picnic, camping, hiking, etc., tents have become an indispensable travel product. Tents can provide people with a temporary resting place to avoid the sun and rain, but tents in daily life It is troublesome in the unfolding process and requires a relatively cumbersome assembly process, which brings certain changes to our use.

Contents of the invention

Purpose of the invention: In order to relieve the inconvenience of tent assembly, this invention proposes a new type of tent, which changes the skeleton form of the traditional tent, realizes the unfolding and folding of the tent perfectly through the opening and closing of the linkage mechanism, avoids the assembly process, and is easy to operate , and it is small in size when folded up, portable and stable, and can be used safely in rainy and snowy weather.

Technical scheme: in order to achieve the above object, the technical scheme adopted in the present invention is:

A new type of hinged and foldable tent without assembly, which is composed of a support frame and a tent cloth covered on the support frame. Composition, the ring mechanism is two, the ring mechanism is composed of 4n diamond-shaped four-bar linkages connected end-to-end through two nodes on the diagonal, where n is a natural number, and are set on the ring mechanism There are four pins, and the pins are located outside the middle node of the diamond-shaped four-bar linkage; the linkage is composed of no less than one four-bar linkage in series, and the four-bar linkage consists of The first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod are connected end to end in sequence, and the lengths of the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod are all the same. The fifth link and the sixth link are connected between the expandable ring mechanism and the ground. The fifth link and the sixth link are the same in length and shorter than the first link. The extension rod of the third connecting rod of the lower four-bar linkage mechanism, the sixth connecting rod is the extension rod of the fourth connecting rod of the lowermost four-bar linkage mechanism, and the third connecting rod of the last four-bar linkage mechanism is connected with the next four-bar linkage mechanism. The first connecting rod of the rod mechanism is a long connecting rod, the fourth connecting rod of the last four-bar linkage and the second connecting rod of the next four-bar linkage are long connecting rods, and the connecting rod is two and arranged at 180 degrees, the top node of the linkage mechanism and the intersection of the fifth and sixth linkages are respectively connected by two pin shafts on the two ring mechanisms; the scissor mechanism consists of no less than one The parallel scissor unit and a bottom polar line scissor unit are connected in series; the scissor mechanism is also two and arranged at 180 degrees, and the first middle of the scissor mechanism is connected by the other two pins on the two ring mechanisms. The node and the last intermediate node are connected to the two-scissor mechanism connecting rod on the upper side of the ring mechanism, and the zipper passes through the other end of the inner connecting rod of the two-scissor mechanism and is fixed on the other end of the outer connecting rod of the two-scissor mechanism .

Both the parallel scissor unit and the epipolar scissor unit are composed of two equal-length connecting rods that are hinged to each other. Length, the length of the hinge point of the two equal-length connecting rods of the polar line scissors unit is equal to the length of the first connecting rod on one side, and the length of the connecting rod on the other side is equal to the length of the fifth connecting rod.

Beneficial effect:

The new type of tent in the invention does not need to be assembled, and the structure is unfolded and fixed to the ground well, and the tent cloth is fastened, which is completed, and the operation is simple; the canopy in the form of double-slope drainage is formed by using the cable to find the slope, and it can still be used safely in rainy and snowy weather; through The design of the asymmetrical scissor unit at the top converts the force of the cables on the structure from horizontal to vertical, avoiding the closure of the structure after the cables are stressed.

The structure tent of the utility model can not only meet the needs of people for temporary rest and entertainment, but also has the advantages of no need for assembly, small volume after folding, portability, stability, etc., and is a must-have product for outdoor activities.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

Figure 1 is a schematic diagram of the support frame structure, as shown in Figure 2, a collapsible tent that does not need to be assembled is connected by a link mechanism 2 connected to an annular link mechanism 1 and a scissor mechanism 3 that fixes a slope-finding cable 4 made.

As shown in Figure 6, the ring-shaped linkage mechanism 1 is composed of 12 diamond-shaped four-bar linkages connected end-to-end through two nodes on the diagonal, and the other two nodes on the other diagonal of the diamond-shaped four-bar linkage are inner ring nodes and the outer ring node, as shown in Figure 9, four pin shafts 7 are evenly arranged radially on the outside of the middle node of the diamond-shaped four-bar linkage mechanism; as shown in Figure 4, the linkage mechanism 2 consists of no less than one four-bar linkage mechanism Composed in series, the first link 9, the second link 10, the third link 11 and the fourth link 12 of the four-bar link mechanism between the two annular link mechanisms have the same length, and the bottom annular link mechanism and the fourth link mechanism have the same length. The fifth connecting rod 13 and the sixth connecting rod 14 between the ground have the same length and are shorter than the above-mentioned connecting rods, the third connecting rod is connected with the first connecting rod and the fourth connecting rod is connected with the second connecting rod It is a long connecting rod, the third connecting rod at the bottom end is connected to the fifth connecting rod, and the fourth connecting rod is connected to the sixth connecting rod. The pin shaft 7 on the ring linkage mechanism 1 is respectively connected to the top node of the linkage mechanism 2 and the intersection of the fifth and sixth linkages; Type unit 6 and a bottom polar line scissor unit 8 are connected in series, and the parallel scissor unit and the polar line scissor unit are shown in Fig. The node 7 on the ring linkage mechanism 1 connects the first intermediate node and the last intermediate node of the scissor mechanism 3, and the drag cables 4 are connected on the two scissor mechanism connecting rods on the upper side of the ring linkage mechanism 1, and the zipper passes through the two The other end of the inner link is fixed to the other end of the two outer links.
