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, saves nunchakus body including at least two and connects the chain of two adjacent joint nunchakus body, corresponding with chain
Nunchakus body end is provided with inner bolt hole, and described chain ends connects the screw arbor assembly corresponding with inner bolt hole coupling.
The locking pull bar of the frustum that described screw arbor assembly includes rear top board, be fixed on rear top board and be set in anti-
Pine pull bar on expansion sleeve, the radius of described locking pull bar is outwards gradually increased by rear top board, described rear top board back with
Chain connects；It is provided with, on described expansion sleeve outer wall, the external screw thread mated with inner bolt hole, blocks between expansion sleeve and rear top board
It is provided with snap ring.
The end of the expansion sleeve corresponding with rear top board offers drive groove, described rear top board is provided with drive recessed
The driving double wedge that groove is corresponding；Multiple tracks expansion slot is offered on the other end sidewall of described expansion sleeve.
The both ends of described nunchakus body are provided with inner bolt hole, and described body fitting chain rod also includes multiple to connected components,
Described includes riser and is arranged on the two screw rods assembly of riser both sides connected components, and described mates respectively to connected components two ends
Docking is fixed with nunchakus body.
Use technique scheme, acquired provide the benefit that:
This utility model reasonable in design, is removably connected by screw thread between its chain and nunchakus body, simultaneously by anti-
Pine pull bar, expansion sleeve, the design of snap ring such that it is able to the phenomenon that the nunchakus body after fastening and chain will not be got loose, make
Obtain nunchakus in use, 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 chain rod be changed to long rod body-building apparatus.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model body fitting chain rod.
Fig. 2 is the structural representation of screw arbor assembly.
Fig. 3 is the structural representation of nunchakus body docking.
Fig. 4 is the structural representation to connected components.
Sequence number in figure: 1 be nunchakus body, 2 for chain, 3 for inner bolt hole, 4 for rear top board, 5 for locking pull bar, 6 for expansion sleeve, 7
For snap ring, 8 be drive groove, 9 for driving double wedge, 10 for riser.
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, save nunchakus body 1 including at least two and connect two adjacent joints
The chain 2 of nunchakus body 1, nunchakus body 1 end corresponding with chain 2 is provided with inner bolt hole 3, and described chain 2 end connects to be had and interior spiral shell
The screw arbor assembly of correspondence is mated in hole 3.
The locking pull bar 5 of the frustum that described screw arbor assembly includes rear top board 4, be fixed on rear top board 4 and being set in
Expansion sleeve 6 on locking pull bar 5, the radius of described locking pull bar 5 is outwards gradually increased by rear top board, described rear top board 4
Back is connected with chain 2；Be provided with, on described expansion sleeve 6 outer wall, the external screw thread mated with inner bolt hole 3, expansion sleeve 6 with after
Between top board 4, card is provided with snap ring 7.The end of the expansion sleeve corresponding with rear top board offers drive groove 8, described rear top board
On be provided with the driving double wedge 9 corresponding with drive groove 8；Offer multiple tracks on the other end sidewall of described expansion sleeve to expand
Groove.
Operation principle of the present utility model is: by rear top board and the drive groove in expansion sleeve with drive joining of double wedge
Close, expansion sleeve is screwed in the inner bolt hole of nunchakus body, after being fully screwed into, rear top board is pulled back, by snap ring be pressed into after top board with
Between expansion sleeve, and snap ring is fastened on locking pull bar, completes to connect and fixes.
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: the both ends of described nunchakus body are provided with inner bolt hole, and described body fitting chain rod also includes multiple
To connected components, described includes riser 10 and is arranged on the two screw rods assembly of riser both sides connected components, described to connected components
Two ends are mated docking respectively and are fixed with nunchakus body, and the rear top board in riser 10 and screw arbor assembly is structure as a whole, thus by right
Multiple nunchakus body can be connected one long rod of formation by connected components.
This utility model reasonable in design, is removably connected by screw thread between its chain and nunchakus body, simultaneously by anti-
Pine pull bar, expansion sleeve, the design of snap ring such that it is able to the phenomenon that the nunchakus body after fastening and chain will not be got loose, make
Obtain nunchakus in use, 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.
