Abstract
The invention relates to a foldable invention rod. Two ends of the invention rod are symmetrically and fixedly provided with more than one extending rod folding mechanisms which are mutually connected; each extending rod folding mechanism is composed of a compression spring core shaft arranged at the end part of the invention rod, a compression spring sleeved on the compression spring core shaft, connecting pieces which are respectively hinged with a spring core shaft and an extending rod through pin shafts, and limiting sleeves which are sleeved on the outer walls of the spring core shaft and the extending rod; the compressing spring is arranged between the invention rod and the extending rod and is at a compressed state; and a dumbbell sheet limiting block is arranged at the outer side end of the extending rod, and a dumbbell sheet placing shaft rod is arranged at the other end of the dumbbell sheet limiting block. According to the invention, the folding function of more than two sections of the foldable invention rod can be used for effectively solving the problem that the invention rod occupies a large area on a packaging aspect and is inconvenient to transport in a transportation process.
Description
Technical field
The present invention relates to a kind of collapsible bar.
Background technology
Barbell is as a kind of sports apparatus commonly used; Because the specification of present widely used bar is different, length also differs, and in use stores and carry inconvenience; Because bar is the rigidity material all, also possibly cause unfavorable conditions such as device damage or carrying injury to personnel in the use.
Summary of the invention
Technical problem to be solved by this invention provide a kind of easy to use, collapsible bar little and easy to carry takes up room.
The present invention adopts following technical scheme:
Bar according to the invention two ends symmetry is set with interconnective bar extension rod fold mechanism more than; Said barbell extension rod fold mechanism by the stage clip mandrel that is arranged on the bar end, be set in stage clip on the stage clip mandrel, through bearing pin respectively with central spindle of the spring and extension rod mutually hinge connector and be set in central spindle of the spring and the extension rod outer wall on limit casing form, said stage clip is arranged between bar and extension rod and is in compressive state; The outboard end of said extension rod is provided with the dumbbell plate limited block, and the other end of said dumbbell plate limited block is provided with dumbbell plate and places axostylus axostyle.
Said extension rod is provided with the damping indentation.
Good effect of the present invention is following:
The present invention is applicable to all size bar of any diameter; Effectively having solved bar through the folder function more than two sections that folds bar takes up room aspect packing greatly and the problem of the inconvenience of carrying in the transportation; Use folding bar convenient flexibly; Directly open the folded portions lock tube and just pin folding connecting portion automatically, the lock tube of leaving behind promptly can turn back, the more effective storage problem that has solved after use.
