Description

Technical Field

[0001] This utility model relates to the field of folding tent technology, and in particular to a lightweight and stable folding tent. Background Technology

[0002] Folding tents, as a convenient outdoor shelter, are widely used in commercial promotion, leisure and entertainment, and emergency operations due to their rapid setup and easy transportation. Traditional folding tents typically use a combination of a frame and a canopy, with a telescopic frame formed by intersecting tubes to achieve deployment and folding. In existing technologies, to ensure the structural continuity of the tent's longitudinal passages and the stability of its lateral support, a common reinforcement scheme involves adding multiple sets of telescopic top poles in the middle of the transverse intersecting tubes, such as the lightweight, quick-setup tent frame disclosed in Chinese Utility Model Patent CN217602291U. However, this structure has significant drawbacks: First, the densely distributed top pole components significantly increase the complexity of the frame system, resulting in a bulky and heavy overall structure, contradicting the requirements for lightweight design; second, the connection nodes between the top poles and the intersecting tubes require adaptation to various irregularly shaped connectors, involving not only the coordinated operation of different functional components such as sliders and hinges, but also requiring multiple sets of specialized molds for parts processing, significantly increasing material management difficulty and manufacturing costs. Therefore, further improvements are needed. Utility Model Content

[0028] Example

[0029] Reference Figures 1 to 4 This utility model proposes a lightweight and stable folding tent, comprising: leg tubes 10, front and rear cross tubes 20, and transverse cross tubes 30; four leg tubes 10 are provided, distributed in a rectangular quadrangular shape; two front and rear leg tubes 10 are hinged together by several front and rear cross tubes to form a side frame assembly 40 that can be folded or unfolded in the front and rear directions; several transverse cross tubes 30 are hinged together to form a transverse frame assembly 50 that can be folded or unfolded in the transverse direction; the transverse frame assembly 50 is hinged to two transverse leg tubes 10 or two transverse front and rear cross tubes 20 in the transverse direction; at the connection of two adjacent transverse cross tubes 30, front and rear cross tubes are provided in the front and rear direction.

[0030] Both the front and rear cross tubes and the transverse cross tube 30 include two connecting tubes that are hinged together in the middle in an X shape; the ends of the connecting tubes are fitted with end sleeves 60, and the connecting tubes and end sleeves 60 have connecting holes 61; the end sleeves 60 are laterally fixed with hinge ears 62; the two parallel connecting tubes are connected by bolts passing through the connecting holes 61 of the two connecting tubes to form a hinged connection; the ends of the two vertically connected connecting tubes are hinged to the hinge ears 62 of the end sleeves 60 of the other connecting tube.

[0031] This invention provides a lightweight and stable folding tent that achieves a balance between lightweight design and high stability through optimized support structure and connection methods. Specifically, it employs a standardized X-shaped hinged connecting pipe and end sleeve 60 combination structure. The front and rear cross pipes 20, the transverse cross pipes 30, and their connection nodes with the leg pipes 10 are all assembled using standardized hinge ears 62 and bolt shafts, significantly simplifying the types of connectors and assembly complexity. Through the cross-linking of adjacent transverse cross pipes 30 and front and rear cross pipes, a distributed force network is formed, effectively transmitting lateral loads, improving overall deformation resistance, and eliminating redundant top rod components, significantly reducing the weight and material cost of the support frame. The lateral hinge ear 62 design of the end sleeve 60 of the connecting pipe allows for hinged connections in the vertical direction without additional irregular connecting blocks, reducing mold types and parts inventory pressure while improving assembly efficiency.

[0032] In this embodiment, the connecting tube is configured as a flat tubular structure. This flat tubular structure preserves sufficient moment of inertia to maintain structural strength while allowing the tube to fit snugly when folded, reducing storage volume.

[0033] In this embodiment, the transverse cross tube 30 includes a first transverse connecting tube 31 and a second transverse connecting tube 32; the length of the second transverse connecting tube 32 is longer than the length of the first transverse connecting tube 31; when the folding tent is in the unfolded state, two adjacent first transverse connecting tubes 31 unfold in a cone shape, and two adjacent second transverse connecting tubes 32 unfold in a straight shape.

[0034] By using first and second transverse connecting pipes 32 of varying lengths, a hybrid support structure combining conical apex and straight sections is formed upon deployment. The conical first transverse connecting pipe 31 enhances the compressive strength at the top, while the straight second transverse connecting pipe 32 optimizes lateral stability, making it particularly suitable for resisting lateral loads in high-wind environments. This design maintains lightweight construction while achieving zoned reinforcement through differentiated pipe lengths, avoiding the localized stress concentration problems caused by traditional uniform supports.

[0035] In this embodiment, the leg tube 10 is equipped with an external slider 11 that can slide up and down; one of the connecting tubes of the front and rear cross tubes and the transverse cross tube 30 is hinged to the top of the leg tube 10, and the other connecting tube is hinged to the external slider 11. Users can quickly adjust the curvature or tilt angle of the tent top by sliding the external slider 11 to adapt to different terrains or sunshade needs. At the same time, the sliding cooperation between the external slider 11 and the leg tube 10 can automatically guide the folding trajectory of the cross tubes during folding, avoiding tube interference and improving the smoothness of folding.

[0036] Furthermore, the outer slider 11 is equipped with an elastic limit switch 12; the leg tube 10 has several positioning holes. Through the cooperation of the positioning holes of the leg tube 10 and the elastic limit pin of the outer slider 11, the locking device of the inner and outer sliders 11 can be released simultaneously by applying force at a single point during operation, making it more convenient and reliable for users to fix and limit the cross tube in the leg tube 10.

[0037] Specifically, the elastic limit pin is equipped with a return spring, which allows the elastic limit pin to be inserted into the positioning hole. The elastic fiber switch can move the elastic limit pin away from the positioning hole.

[0038] In this embodiment, the leg tube 10 is a telescopic sleeve structure. The multi-stage sleeve structure, combined with spring pin positioning, allows for easy adjustment of the overall height of the leg tube 10, thereby adjusting the overall height of the folding tent and facilitating the retraction and storage of the tent.

[0039] Preferably, the hinge ear 62 is a "П"-shaped ear structure. The "П"-shaped hinge ear 62 covers the end of the connecting tube with the ear pieces on both sides, forming a double contact surface constraint.

[0040] In this embodiment, the leg tube 10 is configured as a regular polygon. Through the interlocking effect of the edges of the regular polygon cross-section, the radial rotation problem existing in traditional round or square tubes is completely eliminated, reducing the sliding rotation phenomenon of the slider, making the unfolding or folding of the folding tent more stable.

[0041] Preferably, the leg tube 10 has a hexagonal cross-section. The 120° contact angle between the hexagonal edges and the slider ensures uniform stress distribution at the tube joints, making the overall structure of the folding tent more stable.

[0042] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
