Description

Technical Field

[0001] The utility model relates to the field of tents, in particular to a folding tent support structure. Background Art

[0002] At present, most folding tents are composed of a folding top frame, a plurality of folding side frames, and a plurality of support rods (for example, Chinese patent publication numbers are CN219952899U, CN220434369U, and CN216766971U). The folding top frame is provided with a plurality of side rods that can be expanded to the periphery and contracted from the periphery to the center. The upper end of each support rod is hinged to the lower end of the side rod, and adjacent support rods are connected together by folding side frames.

[0003] Among them, the folding side frames on the existing folding tents are all formed by cross-hinging more than four rods, so the manufacturing difficulty and manufacturing cost of the folding side frames are relatively high.

[0004] In addition, when folding the existing folding tent, it is necessary not only to fold the folding top frame but also to fold the folding side frames at the same time, and the folding of the folding top frame and the folding side frames needs to be kept in a certain synchronization to complete the folding of the folding tent. It is very difficult for one person to fold the existing folding tent, and it is also difficult to synchronize the folding actions when multiple people fold it, so that the folding efficiency is likely to be low.

[0005] At the same time, since the folding side frame is a foldable structure, the limiting effect of the folding side frame is limited. When the folding side frame is hit, it is easy to fold and deform, which easily affects the normal use of the folding tent.

[0006] Therefore, it is very necessary to design a folding tent support structure to solve the above technical problems. Utility Model Content

[0007] The purpose of the utility model is to solve the above-mentioned problems and shortcomings and to provide a folding tent support structure, which has the advantages of simple structure, low manufacturing difficulty, low manufacturing cost, high folding efficiency, stable unfolding, ability to maintain a normal unfolding state for a long time, high reliability, strong applicability, etc.

[0008] The technical solution of the utility model is achieved in this way:

[0009] A folding tent support structure comprises a folding top frame and a plurality of support rods, each support rod is hinged on the folding top frame, and its characteristic is that limit rods are respectively hinged on adjacent support rods, and two limit rods are detachably fixedly connected together.

[0010] Preferably, the two limiting rods are detachably nested and connected together.

[0011] Preferably, the folding tent support structure further comprises a connecting rod, and the two limiting rods are detachably fixedly connected together via the connecting rod.

[0012] Preferably, a spherical head is provided on the end of the limit rod, and a clamping head is provided on the upper end of the support rod. A spherical groove matching the spherical head is provided on the clamping head, and the spherical head can be rotatably embedded in the spherical groove. The limit rod and the support rod are hinged through the spherical head and the spherical groove.

[0013] Preferably, the notch of the spherical groove faces the adjacent support rod, and a clearance gap is provided on the lower notch of the spherical groove for the limiting rod to swing downward to a vertical state.

[0014] Preferably, a swing card frame is provided on the folding top frame, and the swing card frame can be clamped on the unfolded support rod.

[0015] Preferably, the swing bracket includes two limit stop bars, both of which are hinged on the folding top frame, and the two limit stop bars can clamp the support rod together.

[0016] Preferably, the support rod is a telescopic rod.

[0017] Preferably, the folding top frame includes a positioning plate, a sliding plate, a guide rod, and a plurality of diagonal support rods. The diagonal support rods are evenly arranged around the positioning plate, and the upper ends of the diagonal support rods are hinged to the positioning plate so as to swing up and down. The guide rods are vertically arranged at the bottom of the positioning plate, and the sliding plate is vertically slidably arranged on the guide rods. A connecting rod that can swing up and down is hinged on the inner side of each diagonal support rod, and each connecting rod is hinged to the sliding plate, and the support rods are hinged to the lower ends of the diagonal support rods.

[0018] Preferably, the diagonal bracing rod is a telescopic rod.

[0019] The beneficial effects of the utility model are as follows: in the folding tent support structure, the support rod is limited and positioned by two limit rods that are detachably fixedly connected together, so that the number of components used in the existing folding side frames can be reduced, which can make the overall folding tent support structure very simple; and it is more convenient to assemble, thereby reducing the manufacturing difficulty and manufacturing cost.

[0020] By fixing the two limit rods together, the two adjacent support rods can be stably and reliably limited, which can ensure that the folding tent support structure is unfolded very stably, thereby greatly reducing the probability of deformation of the folding tent in the event of a collision, and thus maintaining a normal unfolding state for a long time to avoid being affected by normal use. Such a folding tent support structure has very high reliability and applicability.

[0021] By making the two limit rods detachably connected together, after the connection between the two limit rods is disassembled, the folding of the folding top frame and the swinging of the support rod can be free from restriction, thereby facilitating the rapid folding of the folding top frame and the rapid swinging of the support rod. Therefore, when folding the folding tent support structure, it can be convenient and quick to fold, even one person can operate it, thereby improving the folding efficiency.

[0022] By hingedly connecting the limit rods to the adjacent support rods, it is not only possible to prevent the limit rods from being directly separated from the support rods, but also to facilitate the folding of the folding tent support structure by swinging the limit rods to make the volume of the folded state smaller, which can reduce the difficulty of managing the components. The folding tent support structure is very convenient to store. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 and Figure 2 As shown, the folding tent support structure described in the utility model includes a folding top frame 1 and a plurality of support rods 2. Each support rod 2 is hinged on the folding top frame 1. In order to achieve the invention purpose of the utility model, limit rods 3 are respectively hinged on adjacent support rods 2, and the two limit rods 3 are detachably fixedly connected together.

[0027] In the folding tent support structure, the support rod 2 is limited and positioned by two limit rods 3 that are detachably fixed together. In this way, the number of components used in the existing folding side frame can be reduced, which can make the overall folding tent support structure very simple; and it is more convenient to assemble, thereby reducing the manufacturing difficulty and manufacturing cost.

[0028] By fixing the two limiting rods 3 together, the two adjacent support rods 2 can be stably and reliably limited, which can ensure that the folding tent support structure is unfolded very stably, thereby greatly reducing the probability of deformation of the folding tent in the event of a collision, and thus maintaining a normal unfolding state for a long time to avoid being affected by normal use. Such a folding tent support structure has very high reliability and applicability.

[0029] By making the two limit rods 3 detachably connected together, after the connection between the two limit rods 3 is disassembled, the folding of the folding top frame 1 and the swinging of the support rod 2 can be free from restriction, thereby facilitating the rapid folding of the folding top frame 1 and the rapid swinging of the support rod 2. Therefore, when folding the folding tent support structure, it can be easily and quickly folded, even by one person, thereby improving the folding efficiency.

[0030] By respectively hingedly connecting the limit rods 3 on the adjacent support rods 2, it is not only possible to prevent the limit rods 3 from directly detaching from the support rods 2, but also to facilitate the folding of the folding tent support structure by swinging the limit rods 3 to make the volume of the folded state smaller, which can reduce the difficulty of managing the components. The folding tent support structure is very convenient to store.

[0031] The two limiting rods 3 are detachably nested and connected together, which can facilitate the two limiting rods 3 to be connected together very conveniently and stably, thereby helping to further improve the convenience and stability of assembly.

[0032] like Figure 1 As shown, the folding tent support structure further includes a connecting rod 4, and the two limiting rods 3 are detachably fixedly connected together through the connecting rod 4. This can make the folded tent have a smaller volume, so that it is more convenient to store. This can also facilitate the manufacture of a folding tent support structure with a larger width, and this large folding tent support structure can still be conveniently stored.

[0033] like Figure 1 As shown, the two ends of the connecting rod 4 are connected to the two limit rods 3 by a close nesting connection; or the two ends of the connecting rod 4 are respectively connected to the two limit rods 3 by a threaded sleeve, and when the connecting rod 4 is rotated, the two ends of the connecting rod 4 can be tightened or loosened at the same time. In this way, the actual assembly requirements can be met and the connection can be ensured to be very stable and reliable.

[0034] like Figure 1 and Figure 2 As shown, a spherical head 31 is provided on the end of the limiting rod 3, and a clamping head 21 is provided on the upper end of the support rod 2. A spherical groove 211 matching the spherical head 31 is provided on the clamping head 21. The spherical head 31 can be rotatably embedded in the spherical groove 211, and the limiting rod 3 and the support rod 2 are hinged through the spherical head 31 and the spherical groove 211. This can facilitate the realization of a very stable hinge between the limiting rod 3 and the support rod 2, thereby helping to further improve the reliability of the folding tent support structure.

[0035] When two limiting rods 3 are arranged between adjacent support rods 2, the limiting rods 3 and the spherical heads 31 are rotatably connected together, and the two limiting rods 3 are screwed together or tightly nested together. In this way, when two limiting rods 3 are used, the support rods 2 can be limited, thereby meeting the actual use requirements.

[0036] like Figures 1 to 3 As shown, the notch of the spherical groove 211 faces the adjacent support rod 2, and a clearance notch 212 is provided on the lower notch of the spherical groove 211 for the limit rod 3 to swing downward to a vertical state. This can make the volume smaller after folding, so that it is more convenient to store. In addition, the clearance notch 212 can also be used to limit the limit rod 3, so that the folded structure can be very stable, thereby ensuring the safety of transfer.

[0037] like Figure 1 and Figure 2 As shown, the folding top frame 1 is provided with a swinging bracket 5, and the swinging bracket 5 can be clamped on the unfolded support rod 2. The swinging bracket 5 can play a limiting and reinforcing role between the folding top frame 1 and the support rod 2, so that the folding tent support structure in the unfolded state has higher stability and reliability.

[0038] like Figure 1 and Figure 2 As shown, the swing bracket 5 includes two limit bars 51, both of which are hinged on the folding top frame 1, and the two limit bars 51 can clamp the support rod 2 together. Such a swing bracket 5 is very simple and reliable, which is not only convenient to manufacture, but also has a very good limit effect and can be easily folded.

[0039] like Figure 1 As shown, the support rod 2 is a telescopic rod, which not only facilitates adjusting the height as required, but also allows folding into a smaller volume, which helps to further improve the applicability of the folding tent support structure.

[0040] like Figure 1 As shown, the support rod 2 adopts the existing structure of at least two large tubes covering small tubes to achieve extension and retraction. A positioning hole is opened on the embedding end of the large tube for the small tube, and an elastic telescopic protrusion corresponding to the positioning hole is arranged on the inner end of the small tube. After the support rod 2 is extended, the elastic telescopic protrusion can be embedded in the positioning hole, so that the expansion can be kept stable; and the elastic telescopic protrusion can be manually pressed to exit the positioning hole, so that the restriction can be released to meet the contraction requirements of the support rod 2, thereby meeting the actual use requirements.

[0041] like Figure 1As shown, the folding top frame 1 includes a positioning plate 11, a sliding plate 12, a guide rod 13, and a plurality of diagonal support rods 14. Each diagonal support rod 14 is evenly arranged around the positioning plate 11, and the upper end of the diagonal support rod 14 is hinged on the positioning plate 11 so that it can swing up and down. The guide rod 13 is vertically arranged at the bottom of the positioning plate 11, and the sliding plate 12 is vertically slidably arranged on the guide rod 13. The inner side of each diagonal support rod 14 is hinged with a link rod 15 that can swing up and down, and each link rod 15 is hinged on the sliding plate 12, and the support rod 2 is hinged on the lower end of the diagonal support rod 14. Such a folding top frame 1 is very simple and reliable, which is not only convenient for manufacturing, but also ensures that the folding top frame 1 has extremely high reliability, thereby helping to further improve the reliability and applicability of the folding tent support structure.

[0042] like Figure 1 and Figure 3 As shown, when the sliding plate 12 slides upward, the lower ends of the diagonal support rods 14 can swing synchronously inward; when the sliding plate 12 slides downward, the lower ends of the diagonal support rods 14 can swing synchronously outward, thus meeting the actual folding requirements and thus meeting the actual manufacturing and use requirements.

[0043] like Figure 1 and Figure 3 As shown, the diagonal support rod 14 is a telescopic rod. This can fold into a smaller volume, thereby helping to further improve the convenience of storage of the foldable tent support structure.

[0044] like Figure 1 As shown, the diagonal brace 14 adopts the existing structure of at least two large tubes enclosing small tubes to achieve telescopic expansion. A positioning hole is provided on the embedding end of the large tube for the small tube, and an elastic telescopic protrusion corresponding to the positioning hole is provided on the inner end of the small tube. After the diagonal brace 14 is extended, the elastic telescopic protrusion can be embedded in the positioning hole, so that the expansion can be kept stable; and the elastic telescopic protrusion can be manually pressed out of the positioning hole, so that the restriction can be released to meet the contraction requirements of the diagonal brace 14. The connecting rod 15 is hinged on the tube body at the uppermost end of the diagonal brace 14. In this way, the requirements of actual manufacturing and use can be met.

[0045] like Figures 1 to 3 As shown, two limit stop bars 51 are hinged to the tube body at the lowest end of the diagonal support rod 14 through the same rivet; a hinge notch 141 is provided on the lower end surface of the diagonal support rod 14 to limit the lower end of the support rod 2 from swinging toward the middle of the folding tent support structure; the upper end of the support rod 2 is hinged in the hinge notch 141, so that the lower end of the support rod 2 can swing toward the outside of the folding tent support structure, then swing toward the upper part of the folding tent support structure and be parallel to the diagonal support rod 14. This can help to make the folded tent have a smaller volume, so that it is more convenient to store.

[0046] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
