AI Technical Summary
Existing outdoor tent support frames are inadequate in terms of wind resistance and portability, especially inflatable tents and traditional pole support frames, which are prone to damage and difficult to repair in extreme environments.
The flat, strip-shaped support bar, made of carbon fiber, is hinged to the first and second connectors in the connecting assembly. The support bar is stably inserted using limiting protrusions and guide surface structures, forming a 180° plane to enhance tent stability, while also facilitating folding and replacement.
The tent's wind resistance and portability have been improved. The plug-in structure of the support bars and connecting components makes the tent more stable and allows for quick replacement in case of damage, solving the maintenance and replacement problems of traditional structures.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of oil and gas testing operation technology, specifically relating to a connection structure of a tent frame. Background Technology
[0002] Outdoor tents come in various structures, including inflatable, folding, and modular fixed structures. However, the support frame structure remains the mainstream. While inflatable tents are convenient, they have poor wind resistance. Traditional pole-supported tents, in order to reduce the weight of the tent, have thinner poles, which also result in insufficient wind resistance. Therefore, there is a need to develop a more robust support frame structure that can enable the tent to cope with extreme outdoor environmental changes. At the same time, it is also necessary to ensure stable connections between the support frames and facilitate storage and transport. Utility Model Content
[0003] The purpose of this utility model is to provide a connection structure for a tent frame. The flat strip support bar made of carbon fiber material can provide better toughness and support performance. The support bar is plugged into the connecting component. The first and second connecting parts in the connecting component are hinged to realize the folding function of the tent. At the same time, the folding rotation angle is limited so that the two connected support bars form a 180° plane after unfolding, which can enhance the stability of the tent after unfolding and make the tent have stronger wind resistance.
[0004] This utility model is achieved through the following technical solution:
[0005] A connecting structure for a tent frame includes a connecting component and a support strip. The two ends of the connecting component are respectively inserted and connected to the support strip. The connecting component includes a first connector and a second connector, which are hinged together. The support strip is made of carbon fiber material, has a flat strip structure, a width of 2-3 cm, and a thickness of 0.7-1 cm.
[0006] Preferably, both the first connector and the second connector are provided with a set of limiting protrusions. The limiting protrusions are arranged opposite to each other on both sides of the inner wall of the first connector or the second connector. The limiting protrusions are hemispherical curved surface structures. The end of the support bar is provided with an insertion part. The insertion part is provided with limiting grooves on both sides. The limiting grooves abut against the limiting protrusions.
[0007] Preferably, guide surfaces are provided on both the left and right sides of the end of the plug-in portion, and the guide surfaces are inclined surfaces.
[0008] Preferably, the side of the insertion part is provided with a sliding groove between the guide surface and the limiting groove, and the sliding groove is slidably engaged with the end of the limiting protrusion to allow the limiting protrusion to slide into the limiting groove; the depth of the sliding groove is less than the depth of the limiting groove.
[0009] Preferably, the first connector is provided with a first connecting block, and the first connecting block is provided with a first through hole; the second connector is provided with two second connecting blocks spaced apart, and the end of the second connecting block protrudes from the end of the second connector; the second connecting block is provided with a second through hole, and the second through holes on the two second connecting blocks are coaxially arranged; the width of the first connecting block matches the distance between the two second connecting blocks; the first connector and the second connector are hinged by a pin.
[0010] Preferably, the top surface of the first connecting block is an arc-shaped curved surface structure.
[0011] Preferably, the end of the second connecting block that protrudes from the second connecting member has an arc-shaped curved surface structure.
[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0013] 1) In this utility model, the strip-shaped flat support bar made of carbon fiber material can provide better toughness and support performance. The support bar is plugged into the connecting component. The first and second connecting parts in the connecting component are hinged to realize the folding function of the tent. At the same time, the folding rotation angle is limited so that the two connected support bars form a 180° plane after unfolding, which can enhance the stability of the tent after unfolding, make the tent more wind-resistant, and make the overall weight of the tent lighter and easier to carry. In addition, the support bar is plugged into the connecting component, and the connecting component can be quickly replaced when it is damaged. Traditional fixed structural frames are difficult to repair and replace when damaged.
[0014] 2) In this utility model, a plug-in part is provided on the support bar, a guide surface is provided at the end of the plug-in part, a limiting groove is provided behind the guide surface, and a sliding groove is provided between the guide surface and the limiting groove. At the same time, a limiting protrusion is provided in both the first connector and the second connector of the connecting assembly. When the support bar is inserted into the first connector or the second connector, the guide surface can guide the limiting protrusion to facilitate the insertion of the support bar, and at the same time facilitate the limiting protrusion to slide along the sliding groove. After the limiting protrusion slides into the limiting groove with interference fit, it engages with the limiting groove to keep the support bar stable in the connecting assembly.

A sliding groove 32 is provided on the side of the insertion part between the guide surface 31 and the limiting groove 33, and the sliding groove 32 is connected to the end of the limiting protrusion 4. The sliding fit is used to allow the limiting protrusion 4 to slide into the limiting groove 33. The guide surface 31 can guide the limiting protrusion 4 to facilitate the insertion of the support bar 3, and at the same time facilitate the limiting protrusion 4 to slide along the slide groove 32.
