Abstract
The utility model relates to sports equipment, in particular to width-adjustable parallel bars. The parallel bars comprise upright columns and transverse rods, and further comprise S-shaped connection portions between the upright columns and the transverse rods, axial extension lines of the two ends of each S-shaped connection potion are parallel, the upper end of each upright column is bent in the direction perpendicular to the corresponding transverse rods and is axially and rotatably connected with the lower end of the corresponding S-shaped connection portion, the outer side of the upper end of each upright column and the outer side of the lower end of each S-shaped connection portion are respectively provided with a flange and a bolt pin in a welded mode, each bolt pin is connected with a flange thread hole, the side walls of the transverse rods are provided with connectors connected with the transverse rods perpendicularly, and each connector wraps the upper end of the corresponding S-shaped connection portion and is axially and rotatably connected with the corresponding S-shaped connection portion. The parallel bars adopting the technical scheme are simple in structure and adjustable in width.
Description
Technical field
The utility model relates to a kind of sports equipment, refers to especially a kind of parallel bars of convertible cross bar.
Background technology
Parallel bars are a kind of good exercise equipment, the situation that is limited to place, the quantity of two bars is generally only installed one, but its user who faces generally includes the people of all age group, somebody's hand is less needs that the diameter of cross bar is less just can grab, and somebody's build is healthy and strong, the cross bar of small diameter is got hold of not only uncomfortable, also likely be difficult to bear its larger weight, because the distance between two bar two cross bars is uncontrollable, can not adapt to the different people of most of bodily forms for the individual requirement of width in addition.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple structure, can convert the parallel bars of cross bar.
In order to solve the problems of the technologies described above, the utility model provides a kind of parallel bars of convertible cross bar, include column and cross bar, it is characterized in that: described cross bar is one-sided is provided with three, its end connects by star-shaped support, the middle part of star-shaped support arranges the rotating shaft parallel with three cross bars, is provided with the bearing of fixing described rotating shaft on described column, and the shotpin of locking rotor shaft direction.
Adopt the tool of technique scheme to have the following advantages: owing to mainly including column and cross bar, so construct relatively simple, because cross bar is one-sided, be provided with three, its end connects by star-shaped support, the middle part of star-shaped support arranges the rotating shaft parallel with three cross bars, on described column, be provided with the bearing of fixing described rotating shaft, and the shotpin of locking rotor shaft direction.The user of so different builds can pass through rotating shaft, selects two cross bars of suitable dimension, and make it relative on suitable height, then, with shotpin locking, can use.
As preferred version, in order not interfered by other cross bar after using selected cross bar, provide again as far as possible many cross bar sizes to select for user, described cross bar is uniformly distributed centered by star-shaped support simultaneously, cross bar take middle part as boundary its two ends radially Area Ratio be 1.2.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram for the utility model specific embodiment;
Fig. 2 is the side-looking structural representation for the utility model specific embodiment.
the specific embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
As depicted in figs. 1 and 2, the utility model provides a kind of parallel bars of convertible cross bar, include column 1 and cross bar 2, described cross bar 2 is one-sided is provided with three, cross bar 2 ends are welded to the end of star-shaped support 3, the middle part of star-shaped support 3 arranges and three rotating shafts that cross bar 2 is parallel, on described column 1, be provided with the bearing 4 of fixing described rotating shaft, and the shotpin 5 of locking rotor shaft direction, rotating shaft and and bearing 4 on radial equipartition be provided with circular hole, shotpin 5 is plugged on wherein, described cross bar 2 is uniformly distributed centered by star-shaped support 3, cross bar 2 take middle part as boundary its two ends radially Area Ratio be 1.2, the two ends of a same like this cross bar 2 can provide two kinds of Dimension Types, the user of being convenient to different builds uses.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. the parallel bars of an adjustable width, include column and cross bar, it is characterized in that: also include the S shape connecting portion being arranged between column and cross bar, the two ends of described S shape connecting portion extend axially line parallel, described column upper end is to the direction bending perpendicular to cross bar, and be connected with the lower end axial rotation of described S shape connecting portion, the bolt pin that column upper end is all welded with flange and is connected a flange screw with the outside, lower end of S shape connecting portion, described cross bar sidewall is provided with the connector of perpendicular connection, the upper end of the coated described S shape connecting portion of this connector is also connected with its axial rotation.
2. the parallel bars of adjustable width according to claim 1, is characterized in that: described column upper end is to the direction 45-degree-buckling perpendicular to cross bar.
