Description

Technical Field

[0001] The utility model relates to the technical field of field operation auxiliary equipment, in particular to a portable support rod based on a bistable composite material. Background Art

[0002] As the demand for portable products increases, many portable special equipments have appeared on the market. Among them, a composite material bistable extendable structure is light, simple and easy to operate, which is widely favored by the market.

[0003] In 1998, Lora Chubb Technology Co., Ltd. applied for a patent for an extendable sheet whose shape can change between a first and a second state. However, during the extension process, the extendable sheet has a very unstable region between the first and second states. This unstable region is unstable in subsequent engineering use, often resulting in the entire product failing to meet design requirements or even being unusable. The patent also does not propose a portable structure for the use and installation of the extendable sheet.

[0004] In 2018, the Institute of Aerospace Special Materials and Process Technology applied for a patent for a composite material bistable self-stretching structure and its manufacturing method. The patent did not propose a solution to the instability of the transition zone configuration, and the patent did not propose a portable use and installation structure for the stretching sheet.

[0005] Chengdu Xingye Lei'an Electronics Co., Ltd. filed three patents in 2023, which have achieved certain stabilization and contraction functions for the stretchable sheets. Although solutions are proposed to solve the problems of easy jamming during use and lack of forming support tools, it cannot fundamentally solve the instability of the transition zone configuration; its anti-slip device has a complex structure, large volume, and is not easy to operate. The reinforced ribs not only increase the difficulty of producing bistable composite materials, but also have limited positioning and lack of continuity in elongation; its auxiliary sheet forms a cylindrical forming support with a complex structure, small manual operation space, and great difficulty in operation; it is driven by an electric motor and cannot operate without electricity.

[0006] In order to give full play to the stretchable and easy-to-roll-up characteristics of bistable composite materials and to meet various usage requirements, we have developed products with simple structure, small size, easy operation, no need for electric drive, and high support strength to better meet various operational needs, such as lightning rod support, antenna support, emergency light support, radar support, tent support, etc. Summary of the invention
