Description

Technical Field

[0001] This utility model relates to the field of tent accessories technology, specifically to a frame connection structure for tents. Background Technology

[0002] Tents are commonly used equipment in outdoor camping, emergency rescue, and temporary events. The stability of their frame structure and the ease of assembly directly affect the user experience. Existing tent frame connection structures mostly use single-piece splicing or simple buckle designs, which have the following shortcomings:

[0003] Insufficient connection strength: Traditional splicing structures rely on simple interlocking between poles, which can easily become loose, deformed, or even cause the tent to collapse in outdoor environments with strong winds or uneven stress.

[0004] Limited height and support range adjustment: The support height and lateral support range of most frame connection structures are fixed and cannot be flexibly adjusted according to the tent size and usage scenario (such as use by people of different heights or when more internal space is needed to store more items);

[0005] To address the aforementioned problems, this utility model proposes a frame connection structure for tents. By optimizing the structural design of the connecting frame and adding adjustable support and connection devices, it aims to improve frame stability, enhance adjustment flexibility, and increase assembly efficiency. Utility Model Content

[0006] This invention aims to solve the above-mentioned technical problems by providing a frame connection structure for tents.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0008] A frame connection structure for a tent includes a connecting frame, the upper end of which is equipped with a support device for supporting the top of the tent; multiple sets of support frames are hinged to the outer side of the connecting frame; and a connecting device for connecting the tent is installed at the lower end of the connecting frame.

[0009] Furthermore, the connecting frame includes an upper connecting plate and a lower connecting plate, with multiple sets of supporting trusses installed between the outer sides of the upper and lower connecting plates. The upper and lower connecting plates are made of high-strength plastic or aluminum alloy, ensuring structural lightness while improving load-bearing capacity; the upper and lower connecting plates of the supporting trusses are fixed by welding or bolts to form multiple sets of triangular stable support units, effectively distributing the pressure transmitted between the tent top and the outer support frame, and preventing deformation of the connecting frame.

[0010] Furthermore, the support frame is hinged to the outside of the support truss. The support frame and the support truss are hinged by hinges or pins, allowing the support frame to rotate around the hinge point. This facilitates adjusting the tilt angle of the support frame according to the unfolded size of the tent (e.g., if the unfolded area of ​​the tent is large, the support frame can be rotated outward to expand the support range; when storing, the support frame can be folded towards the connecting frame to reduce the overall volume). At the same time, the hinged structure allows for angle adjustment without tools, improving assembly convenience.

[0011] Furthermore, a support ring is snapped onto the outer side of the support truss. The support ring is made of elastic plastic, and its inner diameter is adapted to the support truss. The angle of the support frame is fixed by the limiting effect of the support ring, preventing the support frame from rotating due to external forces during use, and further improving the stability of the frame.

[0012] Furthermore, the support device includes a connecting pipe with internal threads disposed in the middle of the upper connecting plate. A first threaded rod is internally threaded onto the connecting pipe, and a support block for supporting the tent top is installed at the upper end of the first threaded rod. The connecting pipe is integrally formed or welded to the upper connecting plate to ensure connection strength. The first threaded rod and the connecting pipe are threaded together, and the length of the first threaded rod extending beyond the connecting pipe can be adjusted by rotating the first threaded rod, thereby changing the height of the support block (e.g., if more internal space is needed at the top of the tent, rotating the first threaded rod clockwise raises the support block; conversely, rotating it counterclockwise lowers it). The top of the support block is preferably circular or polygonal, with a rubber pad attached to its upper surface. This increases the contact area with the tent top, preventing excessive local pressure from damaging the tent fabric, and also prevents the tent top from sliding relative to the support block due to the anti-slip properties of the rubber.

[0013] Furthermore, the connecting device includes a second connecting pipe connected to the middle of the lower connecting plate and having internal threads. The second connecting pipe is internally threaded with a second threaded rod, and a connecting plate is installed at the lower end of the second threaded rod. Multiple sets of support arms are hinged to the outer side of the connecting plate. The connection method between the second connecting pipe and the lower connecting plate is the same as that between the first connecting pipe and the upper connecting plate, ensuring structural consistency and stability. The second threaded rod and the second connecting pipe are threaded together, allowing for rotational adjustment of the height of the connecting plate. The support arms are hinged to the connecting plate and, when unfolded, can be connected to the bracket fixing buckle inside the tent, forming multi-directional support to prevent the tent from tipping over. When stored, the support arms can be folded to fit snugly against the connecting plate, reducing space occupation.

[0014] Furthermore, locking nuts are installed on the outer sides of both the first and second threaded rods. The locking nuts are threaded into the first and second threaded rods respectively. After the first threaded rod is adjusted to the target height, the locking nuts are rotated to ensure a tight fit with the upper end face of the connecting pipe, locking the position of the first threaded rod through friction and preventing it from rotating due to vibration or external force. Similarly, the locking nuts can lock the height of the second threaded rod, ensuring the stable and reliable adjustment position of the support device and the connecting device.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. Significantly improved structural stability: The connecting frame forms a multi-triangular stable structure with the upper connecting plate, the lower connecting plate and multiple sets of supporting trusses, which can effectively disperse external forces; the support frame is fixed by the support ring limit, and the support device and the connecting device are locked by the fixing nut to prevent the components from loosening, and the overall wind resistance and deformation resistance are stronger.

[0017] 2. High flexibility of adjustment: The support device can adjust the height of the tent top support through the first threaded rod, and the connection device can adjust the height of the bottom support through the second threaded rod. The support frame can be rotated to adjust the tilt angle, adapting to tents of different sizes and diverse usage scenarios, making it more versatile.

[0018] 3. Easy assembly and storage: Each component adopts a hinged, threaded or snap-fit ​​structure, which can be assembled and disassembled without special tools; the support frame and support arm are foldable to reduce storage volume and make them easy to carry.

The support truss 103 is fixed to the upper and lower connecting plates by argon arc welding, with the welding current controlled at 120-150A, the welding time at 3-5 seconds, and the weld penetration at 2mm. After tensile testing, each set of support trusses 103 can withstand a tensile force of ≥300N without falling off. The support frame 3 is made of the same seamless aluminum alloy tube as the support truss 103, with a length of 300mm; it is hinged to the support truss 103 by a galvanized stainless steel pin with a diameter of 8mm. The fit clearance between the pin and the support frame 3 is 0.15mm, and there is no jamming or shaking during rotation.

[0031] In specific implementation of this utility model, such as Figure 1 and Figure 2 As shown, the support frame 3 is hinged to the outside of the support truss 103. The support frame 3 is made of aluminum alloy tube of the same specifications as the support truss 103. One end of the support frame 3 is hinged to the support truss 103 by a pin. One set of support frames 3 is hinged to the outside of the support truss 103, for a total of 3 sets of support frames 3. The other end of the support frame 3 can be bolted to the bracket of the tent side wall. A rubber washer is fitted on the outside of the pin to increase the friction at the hinge and prevent the support frame 3 from rotating arbitrarily.

[0032] Specifically, a support ring 5 is snapped onto the outer side of the support truss 103. The support ring 5 is made of elastic nylon, and its inner diameter is 1mm smaller than the outer diameter of the support truss 103. It is snapped onto the support truss 103 through elastic deformation. A slot is opened on the outer side of the support truss 103, and the support ring 5 is located in the slot.
