Description
Technical field
This utility model belongs to body-building apparatus technical field, is specifically related to a kind of body fitting chain rod.
Background technology
Nunchakus is sports apparatus conventional in people's daily life, as a kind of protective device and exercise apparatus, binodal
Rod is easy to carry with it, easy to use and very popular；The nunchakus body of existing nunchakus and the connected mode of chain are many
For welding, after using a period of time, it is susceptible to fracture, it is impossible to effectively repair, cause and scrap；If again carried out
Welding, not only affects attractive in appearance, and the motility of nunchakus can be caused to be greatly affected, and easily accidentally injures oneself or other people；
The nunchakus transmutability of present stage is poor simultaneously, and structure is single, it is impossible to meet the application of numerous fans.
Summary of the invention
For the problem and shortage of above-mentioned existence, this utility model provides a kind of reasonable in design, compact, it is possible to effectively
Be attached and fasten, be capable of the body fitting chain rod of the change of multiple multi-form simultaneously.
For solving the problems referred to above, adopted the technical scheme that:
A kind of body fitting chain rod, including at least two joint nunchakus body, the connection sleeve pipe being arranged between adjacent two nunchakus body with fixing set
Putting the screw arbor assembly at nunchakus body two ends, the described sleeve pipe two ends that connect all offer the connection spiral shell being connected with screw arbor assembly coupling
Hole, described screw arbor assembly includes the locking pull bar being fixed on nunchakus body end and the expansion sleeve being set on locking pull bar, described
Locking pull bar be taper type；Be provided with, on described expansion sleeve outer wall, the external screw thread mated with connecting screw hole, expansion sleeve with
It is arranged with snap ring between nunchakus body end, the outer end sidewall of described expansion sleeve offers multiple tracks expansion slot.
Junction slip cap between adjacent two nunchakus body is provided with proof rubber protection set.
The end of the expansion sleeve corresponding with nunchakus body end offers drive groove, and described nunchakus body end is provided with and drives
The driving double wedge that groove is corresponding.
Described body fitting chain rod also includes chain, and chain two ends are provided with union joint, and union joint is provided with connection
Screw.
Use technique scheme, acquired provide the benefit that:
This utility model reasonable in design, many nunchakus body can effectively be docked, thus be formed and add by the application
Long club, adds its usability, it is possible to make chain rod be changed to long rod body-building apparatus, nunchakus body smooth surface, and have protection
Rubber protecting jacket is protected, it is simple to wave.
Meanwhile, its chain and nunchakus body can between removably connected by screw thread, simultaneously by locking pull bar, expansion sleeve,
The design of snap ring such that it is able to make the nunchakus body after fastening and the phenomenon that will not get loose of chain so that nunchakus or many
Joint rod in use, is acted on by tension force, more firmly.

Fig. 1 is one of this utility model structural representation.
Fig. 2 is the attachment structure schematic diagram connecting sleeve pipe.
Fig. 3 is the two of structural representation of the present utility model.
Fig. 4 is the attachment structure schematic diagram of union joint.
Sequence number in figure: 1 be nunchakus body, 2 for connect sleeve pipe, 3 for connecting screw hole, 4 for locking pull bar, 5 for expansion sleeve, 6 for card
Ring, 7 be expansion slot, 8 for drive groove, 9 for drive double wedge, 10 for proof rubber protection set, 11 for chain, 12 be union joint.
Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, this utility model is further described, but this utility model is not limited to
These embodiments.
Embodiment one: see Fig. 1 and Fig. 2, a kind of body fitting chain rod, including at least two joint nunchakus body 1, be arranged on adjacent two nunchakus body
Connecting sleeve pipe 2 and being fixedly installed on the screw arbor assembly at nunchakus body two ends between 1, described connection sleeve pipe 2 two ends all offer with
The connecting screw hole 3 that screw arbor assembly coupling connects, described screw arbor assembly includes locking pull bar 4 and the set being fixed on nunchakus body end
Being located at the expansion sleeve 5 on locking pull bar 4, described locking pull bar 4 is in taper type；Be provided with on described expansion sleeve 5 outer wall with
The external screw thread of connecting screw hole 3 coupling, is arranged with snap ring 6, the outer end of described expansion sleeve 5 between expansion sleeve 5 and nunchakus body 1 end
Multiple tracks expansion slot 7 is offered on portion's sidewall.
Junction slip cap between adjacent two nunchakus body is provided with proof rubber protection set 10, and corresponding with nunchakus body 1 end is swollen
The end of expansion set 5 offers drive groove 8, and described nunchakus body 1 end is provided with the driving double wedge 9 corresponding with drive groove 8.
Operation principle of the present utility model is: by the drive groove in expansion sleeve and the cooperation of driving double wedge, will expand
Set is screwed in the connecting screw hole of nunchakus body, after being fully screwed into, nunchakus body is pulled back, is pressed between nunchakus body and expansion sleeve by snap ring,
And snap ring is fastened on locking pull bar, completes to connect and fix.
Embodiment two: see Fig. 3 and Fig. 4, the structure of the present embodiment is essentially identical with embodiment one, and something in common is the heaviest
Stating, its difference is: described body fitting chain rod also includes chain, and chain two ends are provided with union joint, on union joint
It is provided with connecting screw hole, by the connection of nunchakus body Yu chain, it is possible to form nunchakus or multi-section cudgel.
This utility model reasonable in design, its chain and nunchakus body can between removably connected by screw thread, lead to simultaneously
Cross the design of locking pull bar, expansion sleeve, snap ring such that it is able to make the nunchakus body after fastening and showing of will not getting loose of chain
As so that nunchakus in use, is acted on by tension force, more firmly.
Meanwhile, many nunchakus body can effectively be docked by the application, thus forms the club of lengthening, adds it and makes
By property, it is possible to make nunchakus be changed to long rod body-building.
This utility model is not limited to above-mentioned detailed description of the invention, and those skilled in the art also can make multiple change accordingly
Change, but any be equal to this utility model or similar change all should be contained in the range of this utility model claim.
