Embodiment Construction

[0016] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0017] Such as Figure 1 to Figure 5 As shown, the variable rod is characterized in that it includes a plurality of hard bodies 1 connected in series by an inelastic rope 2, one end of the inelastic rope 2 is linked with a tension locking device 3, and the inelastic rope The other end of 2 is provided with end 21.

[0018] Further, the upper end surface of the hard body 1 is provided with a protrusion 12 , the lower end surface of the hard body 1 is provided with a groove 13 , and the middle of the hard body 1 is provided with a hole 11 for the inelastic rope 2 to pass through.

[0019] Further, the tension locking device 3 is provided with a through hole 31 for passing through the inelastic rope 2 and a rotating d...

Abstract

The invention relates to the technical field of rod pieces, in particular to a variable rod piece. The variable rod piece is characterized by comprising a plurality of hard bodies which are connectedin series through a nonelastic rope, one end of the nonelastic rope is connected with a tensing locking device, and the other end of the nonelastic rope is provided with an end socket. According to the variable rod piece, the nonelastic rope is tensed through the tensing locking device, the parallel outer facades of the multiple hard bodies are tightly compacted, joint faces of the corresponding hard body and the tensing locking device are tightly compacted, and protrusions arranged on the hard bodies and grooves formed in the hard bodies are matched with one another; after a locking device onthe tensing locking device is locked, a straight rod is formed, otherwise, after the locking device is unlocked, gaps are formed between the parallel outer facades of the multiple hard bodies connected on the nonelastic rope in series, and a free bending rod can be formed; and switching between the bent mode and the straight mode of the rod piece as well as switching between the flexible mode andthe hard mode of the rod piece can be achieved, and the variable rod piece is simple in structure, easy to produce, convenient to operate and wide in application range.

Description

technical field [0001] The invention relates to the technical field of rods, in particular to a variable rod. Background technique [0002] Most of the existing luggage pull rods are rigid curved or straight, and some rods are flexible curved or straight. The rods cannot be switched between curved and straight, soft and hard, and the use methods are relatively limited and not convenient enough. Contents of the invention [0003] The purpose of the present invention is to avoid the defects of the prior art and provide a variable rod, which effectively solves the problems of the prior art. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: the above-mentioned variable rod, which is characterized in that it includes a plurality of hard bodies connected in series through inelastic ropes, and one end of the inelastic ropes is locked with tension. The device is linked, and the other end of the non-elastic rope is provided ...
