Abstract
The utility model discloses parallel bars with adjustable height and width. The parallel bars comprises a rectangular base, upright posts arranged at the four corners of the base, and two cross bars connected to the upper ends of the upright posts, wherein each base comprises two width rods and two length-adjustable length rods; each upright post comprises an upright post body connected with the base, and an inverted L-shaped connecting rod connected to the upper part of the upright post body; the lower ends of the L-shaped connecting rods can rotate and be connected with the upright post bodies in a manner of moving up and down; connecting blocks are arranged on the bottom surfaces of the cross bars; and the upper ends of the L-shaped connecting rods are rotationally connected with the connecting blocks respectively. The parallel bars with adjustable height and width have the following advantages: when the L-shaped connecting rods move up and down respectively, the height of the parallel bars can be changed accordingly; and when the L-shaped connecting rods rotate respectively, and the distance between the length rods is adjusted adaptively, the width of the parallel bars can be adjusted conveniently. Therefore, the height and the width of the parallel bars of the utility model can be adjusted conveniently as required.
Description
Technical field
The utility model relates to a kind of sports equipment, is meant a kind of width and highly all adjustable parallel bars especially.
Background technology
Parallel bars are a kind of good exercise equipment, and in the colleges and universities of present most of middle schools and non-sports speciality, teaching all is uncontrollable with the distance between the distance between two cross bars of two bars and two cross bars and the ground.And because user's rising and brachium all have bigger difference, therefore uncontrollable pair of bar of this distance can not adapt to most of people's personalized requirement.
The utility model content
The utility model provides a kind of can regulate two bars that the cross bar height can be regulated the cross bar spacing again, and its purpose is to overcome the problems referred to above that prior art exists.
The technical solution of the utility model is as follows:
A kind of height and broad-adjustable parallel bars comprise the base of rectangle, two parallel cross bars being located at the column in base four bights and being connected in the column upper end, and described base comprises two width rods and two length rods with adjustable in length; Described column comprises column body that is connected with base and the inverted L shaped connecting rod that is connected in column body top, and the lower end of described L shaped connecting rod is rotatable and can be connected in the column body up or down; The bottom surface of described cross bar is provided with contiguous block, and the upper end of described L shaped connecting rod is connected with contiguous block respectively rotationally.
As improvement of the present utility model, four bights of described base are provided with the stabiliser bar that parallel bars are steadily placed, and described width rod and the stabiliser bar that is connected with the width rod two ends respectively and column body are welded to each other and form the U-shaped support.
As further improvement of the utility model, the lower end of described U-shaped support is welded with adjusting rod, and the length rod body that described length rod comprises adjusting rod and is sheathed on adjusting rod screws tight between described adjusting rod and the length rod body mutually.
As improvement of the present utility model, described column body is sheathed on L shaped connecting rod lower end.
Further improve as of the present utility model, the material of described cross bar is an elasticity fiberglass.
Compared with prior art to description of the present utility model as can be known by above-mentioned, advantage of the present utility model is: when L shaped connecting rod carries out upper and lowerly when mobile respectively, the height of parallel bars just can and then change; When L shaped connecting rod rotates respectively, when simultaneously the length rod distance being carried out the adaptability adjusting, just can regulate the width of parallel bars easily, therefore parallel bars of the present utility model can be carried out the adjusting of height and width as required easily.
Description of drawings
Fig. 1 is the novel structural representation of this use.
The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
With reference to Fig. 1, a kind of height and broad-adjustable parallel bars, comprise that the base 1 of rectangle, two parallel cross bar 3(cross bars 3 being located at the column 2 in base 1 four bights and being connected in column 2 upper ends are made by elasticity fiberglass usually), four bights of base 1 are respectively equipped with the stabiliser bar 6 that parallel bars are steadily placed.Base 1 comprise among two width rod 4(figure only draw one) with two with the length rods 5 of adjustable in length; The inverted L shaped connecting rod 22 that column 2 comprises the column body 21 that is connected with base 1 and is connected in column body 21 tops, column body 21 are sheathed on L shaped connecting rod 22 lower ends, and the lower end of L shaped connecting rod 22 is rotatable and can be connected in column body 21 up or down; The bottom surface of cross bar 3 is provided with contiguous block 31, and the upper end of L shaped connecting rod 22 is connected with contiguous block 31 respectively rotationally.
Continuation is with reference to Fig. 1, and width rod 4 and the stabiliser bar 6 that is connected with width rod 4 two ends respectively and column body 21 are welded to each other and form the U-shaped support.The lower end of U-shaped support is welded with adjusting rod 51, and the length rod body 52 that length rod 5 comprises adjusting rod 51 and is sheathed on adjusting rod 51 screws tight between described adjusting rod 51 and the length rod body 52 mutually.
When L shaped connecting rod 22 carries out upper and lowerly when mobile respectively, the height of parallel bars just can and then change; When L shaped connecting rod 22 rotates respectively, when simultaneously length rod 5 distances being carried out the adaptability adjusting, just can regulate the width of parallel bars easily, therefore parallel bars of the present utility model can be carried out the adjusting of height and width as required easily.
Above-mentioned only is the specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
