Supporting device made of retractable supporting rods

Abstract

The invention relates to a supporting device made of retractable supporting rods, at least three supporting rods and an upper center clamping piece are arranged, and each supporting rod is formed by combining a retractable supporting rod and a group of clamping head assemblies on the retractable supporting rod; the retractable supporting rod is made of a bistable composite material structure body, when the retractable supporting rod is in a working state, the retractable supporting rod extends to form a main stable straight pipe which is rolled up in the axial direction of a long side and has a C-shaped section, and when the retractable supporting rod is in a non-working state, the retractable supporting rod is a sub-stable rolling belt rolled up in the axial direction of a short side; the group of clamping head assemblies at least comprise an upper end part clamping head assembly and a lower end part clamping head assembly, and further comprise more than one middle clamping head assembly; each clamping head assembly adopts a pull buckle type locking structure or an eccentric clamping structure; the upper end of each supporting rod is provided with a connector connected with the upper center clamping piece. The device has the advantages of small size, light weight, high strength, high erection, quick deployment and the like, can be carried by a single person, is particularly suitable for being used under the condition that a vehicle cannot reach, and can provide powerful guarantee for quickly constructing an emergency network.

Description

technical field [0001] The invention relates to a support facility, in particular to a support structure composed of retractable struts. Background technique [0002] As the country's requirements for emergency response capabilities are getting higher and higher, this requires a large number of voice and video signals at the scene of the incident to be transmitted back to the rear headquarters in time, so it is very necessary to ensure smooth communication. [0003] At the scene of an emergency, some mobile communication equipment (such as antennas, cables, base transceiver stations, base station controllers, etc.) must be installed. How to effectively ensure the stability, safety and reliability of the installed mobile communication equipment requires good supporting facilities. [0004] Taking the mast currently used for erection as an example, the communication masts used by various manufacturers have the following disadvantages: [0005] 1. Large size [0006] Existin...

AI Technical Summary

Problems solved by technology

[0006] Existing portable masts are all designed and manufactured on the basis of telescopic rods. If you want to reach a certain height, the initial state also requires a certain volume, which makes it inconvenient to carry

[0007] 2. Self-heavy

[0008] Too many mechanical structures lead to its own weight, which is inconvenient to carry and transport

[0009] 3. Complex structure and poor overall performance
