Problems solved by technology

The poles of this structure can be assembled into the framework required for the tent. This solution can further reduce the volume of the disassembled bracket or tent, but there are still disadvantages of inconvenient use and many operating steps, especially when the pole For a long time, the state after loosening and folding is irregular, and it is easy to get knotted, which is not conducive to the next time to prop up the frame, causing inconvenience to the next tension.

Embodiment Construction

[0034] Shrink Rod Example:

[0035] Referring to FIG. 1 , the retractable rod 100 is composed of a plurality of rigid joints 110 with convex and concave portions connected in series by two flexible cables 130 in series. The storage part is composed of a rotatable rotating shaft 101, a storage rod sleeve 103 fixed on the rotating shaft 101 in a linkage manner of intermittent transmission, and a pair of cable protection plates 104 located at both ends of the storage rod sleeve 103. The two cable protection plates A cable storage space 105 is formed between 104 , and in this example, the rod storage sleeve 103 is rotatably connected to the cable protection plate 104 through a bearing 102 . One end of the two flexible cables 130 passes through the rod storage sleeve 103 and is fixed on the rotating shaft 101 . The other ends of two flexible cables 130 are fixed on the tensioning part, and the tensioning part is made of fixed foot and spring 145, and the spring 145 as elastic memb...

Abstract

The invention relates to a shrinkage rod and a tent made with the shrinkage rod. The shrinkage rod comprises a plurality of rigid skeleton-joints with two axial ends and sides, the concave and convex parts of all skeleton-joints are connected in series along the through holes by two flexible ropes sequentially; the shrinkage rod additional comprises a storage section located at one end of the rod for storing the rod in a coiled way. The storage section is provided with a rotatable rotary shaft, and a rod-storage sleeve is fixed on the rotary shaft in linkage way in form of intermittent drive; one end of the two flexible ropes pass the rod-storage sleeve and are fixed on the rotary shaft; the rod-storage sleeve is borne rotatably between two rope-protecting boards at two ends of the sleeve; a tension part is provided at another end of the shrinkage rod; another end of the two flexible ropes are fixed on the tensioning part. The shrinkage rod can be retracted and released sequentially, a tent made with the rod has the advantage of the smaller retracted size comparing with a prior tent.

Description

technical field [0001] The invention relates to a shrink rod and a tent made of the shrink rod. Background technique [0002] Some temporary objects supported by frames, such as advertising billboards, camping tents, etc., have the characteristics of disassembly and assembly. They are mostly assembled into frames with rods and rod connectors with a certain length, and advertising boards or tent cloths are tied. The detachable frame has the characteristics of small size and easy retraction after the parts are disassembled, but each rod still has a certain length, and the characteristics of easy retraction because the rods can no longer be retracted are not very good. obvious. [0003] CN1027657C Chinese Invention Patent Specification discloses an invention called "spine tent bracket". The disclosed bracket is composed of several plastic pipe joints or metal pipe joints, which are connected in series with steel wire ropes and tensioned to form an arch. Rigid brackets of vari...
