Description

Technical Field

[0001] This utility model relates to the field of outdoor products technology, and in particular to a highly stable tent frame. Background Technology

[0002] As the core framework supporting the entire tent structure, the tent frame's stability directly determines the tent's overall performance. Currently, most tent frames on the market are constructed by assembling multiple metal poles, which are then connected using specialized connectors.

[0003] However, existing metal poles and connectors mostly use a plug-in structure design. With this connection method, it's often difficult to achieve a completely tight fit between the metal poles and the connector's insertion holes, inevitably resulting in a certain gap. This gap causes relative wobbling between the pole assembly and the connector during use, leading to poor stability of the entire tent frame, making it prone to shaking and affecting the tent's safety and reliability. Summary of the Invention

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, a highly stable tent frame includes pole assembly 1 and connector 2. The end of pole assembly 1 is provided with connector 3. Connector 3 includes main body component 3-1. The main body component 3-1 is provided with several expansion flaps. The expansion flaps are composed of an outer metal layer 3-3 and an inner metal layer 3-4. The coefficient of thermal expansion of the outer metal layer 3-3 is greater than that of the inner metal layer 3-4. Adjacent pole assemblies 1 are connected by connector 2. Connector 2 includes a sleeve 2-2 for inserting pole assembly 1.

[0021] In use, this invention first heats the expansion flap on the connector 3 using a heating device such as a flame gun, raising its temperature to over 200°C. When the expansion flap is heated, the outer metal layer 3-3 has a greater coefficient of thermal expansion than the inner metal layer 3-4, resulting in a greater thermal expansion of the outer metal layer 3-3 than the inner metal layer 3-4. This causes the expansion flap to bend inward as its temperature rises (i.e., the expansion flap contracts inward). Then, the connector 3 with the expansion flap is inserted into the sleeve 2-2 on the connector 2. As the expansion flap cools, it gradually returns to its initial state, bending outward (i.e., the expansion flap expands outward). The expansion flap then firmly presses against the inner wall of the sleeve 2-2, ensuring a tight fit between the connector 3 and the sleeve 2-2 of the connector 2. This significantly reduces or even eliminates the gap between them, fundamentally suppressing the relative swaying between the connector 2 and the pole assembly 1, thereby greatly improving the stability of the entire tent frame. When it is necessary to disassemble the tent frame, the connector 2 is heated first to cause the expansion valve to contract inward, thereby separating the pole assembly 1 from the connector 2.

[0022] This invention effectively ensures the stability of the tent frame and facilitates installation and disassembly.

[0023] In this utility model, the rod assembly 1 is made of a circular steel pipe.

[0024] The expansion petals are arranged in a circular array on the main body component 3-1.

[0025] The expansion flap has a protrusion 3-5, and the inner wall of the sleeve 2-2 has an annular groove 2-3 for engaging with the protrusion 3-5. The surface of the protrusion 3-5 is an arc surface. In this application, the engagement structure of the protrusion 3-5 on the expansion flap and the corresponding annular groove 2-3 on the inner wall of the sleeve 2-2 can further enhance the connection stability of the tent frame. When the pole assembly 1 is connected, when the expansion flap expands outward, the protrusion 3-5 on the expansion flap will precisely embed into the annular groove 2-3 on the inner wall of the sleeve 2-2, forming a physical snap-fit ​​fixation; this structure not only achieves a tight fit of surface contact through the expansion force of the expansion flap, but also forms radial and axial limits through the mechanical interlocking of the concave and convex structure, effectively preventing possible axial sliding or circumferential rotation between the pole assembly 1 and the connector 2, thus effectively improving the connection strength between the two.

[0026] In this embodiment, the main body component 3-1 has a cylindrical structure. The outer diameter of the main body component 3-1 is adapted to the inner diameter of the sleeve 2-2.

[0027] The main body component 3-1 is made of metal, and the expansion flaps are welded to it. The metal construction of the main body component 3-1 provides excellent thermal conductivity. Before installation, the expansion flaps can be heated by blowing a flame into the main body component 3-1. The main body component 3-1 will conduct heat to each expansion flap, raising their temperature simultaneously. This eliminates the need for individual heating of each flap; simply blowing a flame into the main body component 3-1 is sufficient. Because the metal main body component 3-1 conducts heat rapidly and evenly, heat is quickly conducted to each expansion flap through the welding points, causing all flaps to heat up synchronously. When the end of the pole assembly 1 is inserted into the sleeve 2-2, a portion of the main body component 3-1 will protrude outside the sleeve 2-2. This exposed portion can be used as a heating point when the tent frame needs to be disassembled. Heating this exposed portion causes the expansion flaps to contract inward, facilitating separation between the pole assembly 1 and the connector 2.

[0028] The main body component 3-1 is provided with an insertion part 3-2, which is a cylinder and the diameter of the insertion part 3-2 is adapted to the inner diameter of the rod assembly 1; the main body component 3-1 and the rod assembly 1 are welded together.

[0029] like Figure 4 As shown, the connector 2 also includes a spherical body 2-1, and a sleeve 2-2 is disposed on the spherical body 2-1. The connector 2 is made of steel.

[0030] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
