Description

Technical Field

[0001] The invention relates to the technical field of tents, and in particular to a lightweight folding tent frame. Background Art

[0002] As people pursue a richer life, outdoor activities have become the main choice for people to relax and broaden their horizons, such as BBQ, picnics and camping. These activities usually require tents to withstand the changing weather and deal with the wind, sand and dust in the wild. At the same time, because the more people participate, the more lively it is, and the tents must be large enough to accommodate enough people. Family cars cannot carry tents that can meet the capacity requirements, and existing lightweight tents are difficult to meet the capacity requirements, and often need to put two or three tents side by side for use. If the above-mentioned entertainment activities only cause inconvenience in carrying and using, if they are used in outdoor emergency activities such as disaster relief, a lot of rescue and disaster relief time will be wasted, resulting in a large number of casualties and property losses. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention proposes a lightweight folding tent frame that is easy to fold and carry, has a stable structure, and has a sufficiently large covering range and space size. The specific technical solution is as follows:

[0004] A lightweight folding tent frame is provided with a pole assembly, the pole assembly is composed of pole 1, pole 2, pole 3 and pole 4, and a transverse telescopic mechanism is provided between the pole 1, pole 3 and pole 4 and between the pole 1, pole 3 and pole 2. The tent can be unfolded by the transverse telescopic mechanism, and a stable vertical structure is formed by using the pole assembly;

[0005] A middle support mechanism is arranged in the middle of the plane where the first, second, third and fourth vertical poles are located, and a telescopic bracket assembly is arranged between the middle support mechanism and the transverse telescopic mechanism, and the telescopic bracket assembly is arranged upwardly from the transverse telescopic mechanism to the middle support mechanism. The telescopic bracket assembly cooperates with the middle support mechanism to simultaneously unfold the tent into an arch shape and shape it, so that the structure is more stable, the ability to resist wind, sand, rain and snow is stronger, and it is conducive to the rapid sliding of rain and snow, and no water and snow will accumulate on the top. The telescopic bracket assembly can save more materials to achieve the purpose of lightness. At the same time, the length and number of the poles are less, which is more conducive to carrying, and can form a more stable structure, with stronger resistance and a larger coverage range.

[0006] As an optimization: the lateral telescopic mechanism is provided with at least one telescopic rod group, the telescopic rod group is provided with a first support rod and a second support rod, the first support rod and the second support rod are cross-arranged at the middle part and are hinged together;

[0007] A sliding support block is sleeved on the middle part of the vertical pole one, the vertical pole two, the vertical pole three and the vertical pole four, and a first hinge joint is arranged on the sliding support block. A second hinge joint is arranged on the top of the vertical pole one, the vertical pole two, the vertical pole three and the vertical pole four, and the first support rod and the second support rod are hingedly installed with the second hinge joint and the first hinge joint respectively.

[0008] As an optimization: the lateral telescopic mechanism is provided with three telescopic rod groups connected in sequence, wherein the first, second and third telescopic rod groups are connected and installed with hinged mounting parts, and the ends of the first support rod and the second support rod in different telescopic rod groups are cross-hinged and installed through hinged mounting parts.

[0009] As an optimization: the telescopic bracket assembly is a two-in-one telescopic bracket, which includes a middle support rod group and two branch support rod groups, and a two-in-one hinge joint is provided between the middle support rod group and the branch support rod group;

[0010] The middle support rod group includes a first support rod and a second support rod, wherein the first support rod is longer than the second support rod, and the first support rod and the second support rod are hinged in the middle; the sub-support rod group includes a first sub-support rod and a second sub-support rod, wherein the second sub-support rod is longer than the first sub-support rod, and the first sub-support rod and the second sub-support rod are hinged in the middle;

[0011] The ends of the two first branch support rods are hingedly installed with the first support rod through a two-in-one hinge joint, and the ends of the two second branch support rods are hingedly installed with the second support rod through a two-in-one hinge joint. An oblique hinge seat is arranged on the hinge mounting piece, and the other ends of the first branch support rod and the second branch support rod are respectively installed on different oblique hinge seats. Since the length difference between the first support rod and the second support rod and the first branch support rod and the second branch support rod is large, the height difference between the top and bottom ends of the middle support rod group and the branch support rod group is larger, so that the height difference between the middle support mechanism supported by the telescopic bracket assembly and the surrounding lateral telescopic mechanism is larger, so that the internal space height of the tent is higher, which is more conducive to the activities of people inside the tent.

[0012] As an optimization: the middle support mechanism is provided with a support column, and an upper sliding seat and a lower sliding seat are respectively sleeved in the middle of the support column, and hinged mounting heads are arranged around the upper sliding seat and the lower sliding seat, and the first support rod and the second support rod are respectively hingedly mounted on different hinged mounting heads, and a limited locking mechanism is arranged on the lower sliding seat for fixing the lower sliding seat to the support column, and a support plate is also arranged on the top of the support column.

[0013] As an optimization: the vertical pole one, vertical pole two, vertical pole three and vertical pole four are all retractable square poles or round poles.

[0014] The beneficial effects of the present invention are as follows: 1. The first support rod and the second support rod are cross-hinged with the first branch support rod and the second branch support rod, which greatly increases the height of the internal space, thereby improving the comfort of use. At the same time, the length of the vertical pole can be shortened or the number of stretching sections can be shortened, which is more convenient to carry and improves the strength of the vertical pole. The top has a greater slope relative to the surroundings, which is convenient for rapid drainage of rain and snow, and avoids the tent cloth being crushed by accumulated rain or snow;

[0015] 2. The setting of the middle support mechanism in the middle improves the support strength and height of the entire tent frame. The sliding seat and support column are used to improve the support flexibility and facilitate folding;

[0016] 3. Through the cross connection and extension of the horizontal telescopic mechanism, different expansion degrees can be opened according to needs, which can be applied to more flexible and changeable environments;

[0017] 4. The main support arch of the tent adopts a two-in-one telescopic bracket assembly, forming a more stable triangular structure with stronger resistance and a larger coverage area. At the same time, the quality and volume are relatively lighter, saving materials and making it easier to carry and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0029] Embodiment 1:

[0030] like Figure 1 , Figure 2 and Figure 3 As shown: a lightweight folding tent frame is provided with a pole assembly 1, which is composed of a pole 1 11, a pole 2 12, a pole 3 13 and a pole 4 14. The pole 1 11, the pole 2 12, the pole 3 13 and the pole 4 14 are all retractable square poles, or round poles. A transverse telescopic mechanism 2 is provided between the pole 1 11, the pole 3 13 and the pole 4 14 and between the pole 1 11, the pole 3 13 and the pole 2 12. The tent can be unfolded by the transverse telescopic mechanism 2, and a stable vertical structure is formed by using the pole assembly. Different unfolding degrees can be opened according to needs, so that the tent can be applied to a more flexible and changeable environment.

[0031] A middle support mechanism 3 is arranged in the middle of the plane where the pole 1 11, the pole 2 12, the pole 3 13 and the pole 4 14 are located. The middle support mechanism 3 and the pole assembly 1 are used to set the supporting tent cloth, and the height of the top of the middle support mechanism 3 in the unfolded state is much higher than the top of the pole assembly 1. A telescopic bracket assembly 5 is respectively arranged between the middle support mechanism 3 and the transverse telescopic mechanism 2. The telescopic bracket assembly 5 is inclined upward from the transverse telescopic mechanism 2 to the middle support mechanism 3, so that the middle support mechanism 3 can indirectly rely on the telescopic bracket assembly 5 and the transverse telescopic mechanism 2 to act on the pole assembly 1 erected on the ground, thereby obtaining supporting force. At the same time, in the unfolded state, the telescopic bracket assembly 5 cooperates with the middle supporting mechanism 3 to unfold the tent into an arch shape and shape it at the same time. The structure is more stable, the ability to resist wind and sand is stronger, and it is conducive to rainwater sliding down, and no water will accumulate on the top. The telescopic bracket assembly can save more materials to achieve the purpose of lightness. At the same time, the length and number of support poles are less, which is more conducive to carrying in the trunk of a family car, and can form a more stable triangular structure with stronger resistance and a larger coverage range.

[0032] The above-mentioned lateral telescopic mechanism 2 is provided with three telescopic rod groups 21 connected in sequence, and the telescopic rod group 21 is provided with a first support rod 211 and a second support rod 212. The first support rod 211 and the second support rod 212 are cross-arranged in the middle and hinged together, wherein the first, second and third telescopic rod groups 21 are all provided with hinged mounting parts 213 for connection and installation, and the ends of the first support rod 211 and the second support rod 212 in different telescopic rod groups 21 are cross-hinged and installed through the hinged mounting parts 213.

[0033] A sliding support block 22 is sleeved on the middle of the above-mentioned vertical pole 11, vertical pole 2, vertical pole 3, vertical pole 13 and vertical pole 4, and a first hinge joint 23 is arranged on the sliding support block 22. A second hinge joint 24 is arranged on the top of the vertical pole 11, vertical pole 2, vertical pole 3, vertical pole 13 and vertical pole 4, and the first support rod 211 and the second support rod 212 are hingedly installed with the second hinge joint 24 and the first hinge joint 23 respectively.

[0034] The telescopic bracket assembly 5 is a two-in-one telescopic bracket, which includes a middle support rod group 51 and two branch support rod groups 52 , and a two-in-one hinge joint 53 is provided between the middle support rod group 51 and the branch support rod group 52 .

[0035] The above-mentioned middle support rod group 51 includes a first support rod 511 and a second support rod 512, wherein the length of the first support rod 511 is longer than that of the second support rod 512, and the first support rod 511 and the second support rod 512 are hinged in the middle; the branch support rod group 52 includes a first branch support rod 521 and a second branch support rod 522, wherein the length of the second branch support rod 522 is longer than that of the first branch support rod 521, and the first branch support rod 521 and the second branch support rod 522 are hinged in the middle.

[0036] The ends of the two first division support rods 521 are hingedly mounted to the first support rod 511 via a two-in-one hinge joint 53, and the ends of the two second division support rods 522 are hingedly mounted to the second support rod 512 via a two-in-one hinge joint 53. A beveled hinge seat 54 is provided on the hinge mounting member 213, and the other ends of the first division support rod 521 and the second division support rod 522 are respectively mounted on different beveled hinge seats 54.

[0037] Since the length difference between the first support rod 511 and the second support rod 512, and the first branch support rod 521 and the second branch support rod 522 is relatively large, the height difference between the top and bottom ends of the middle support rod group 51 and the branch support rod group 52 is larger, so that the height difference between the middle support mechanism 3 supported by the telescopic bracket assembly 5 and the surrounding lateral telescopic mechanism 2 is larger, so that the internal space height of the tent is higher, which is more conducive to the activities of people inside the tent.

[0038] The above-mentioned middle support mechanism 3 is provided with a support column 31, and an upper sliding seat 32 and a lower sliding seat 33 are respectively sleeved in the middle of the support column 31, and hinged mounting heads 54 are arranged around the upper sliding seat 32 and the lower sliding seat 33. The first support rod 511 and the second support rod 512 are respectively hingedly mounted on different hinged mounting heads 54, and a limited locking mechanism 35 is arranged on the lower sliding seat 33 for fixing the lower sliding seat 33 and the support column 31. A support plate 4 is also arranged on the top of the support column 31. The support plate 4 has a protective effect of increasing the contact surface and reducing the pressure for the cloth sleeved on the tent frame. At the same time, a pull rope can also be connected to the support plate 4 to enhance the overall stability of the tent.

[0039] Embodiment 2:

[0040] like Figure 4 As shown: As an optimization, when other structures are the same as those in Example 1, the above-mentioned lateral telescopic mechanism 2 is provided with two telescopic rod groups 21 connected in sequence, and the above-mentioned telescopic bracket assembly 5 cancels the two-in-one hinge joint 53, that is, the telescopic bracket assembly 5 is not a two-in-one telescopic bracket, and the middle support mechanism 3 is directly supported by the middle support rod group 51 to meet the needs of building a tent with a small area. A triangular hinge seat 55 is provided between the two telescopic rod groups 21, and the two telescopic rod groups 21 and the middle support rod group 51 are hinged together through the triangular hinge seat 55 to realize a synchronous telescopic function, and the two telescopic rod groups 21 are respectively hinged to the two opposite flat head ends of the triangular hinge seat 55, and the right-angle end of the triangular hinge seat 55 is hinged to the component of the telescopic bracket assembly 5.

[0041] Rope holes are provided on the support plate 4 and each upright pole of the upright pole assembly 1, and ropes 7 are provided in the rope holes. The ropes 7 make the support plate 4 and the upright pole assembly 1 more tightly installed without adding too much weight, so that the tent is built more firmly. The ropes 7 can also be grounded and tightened to enable the tent to withstand greater wind and sand.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims.
