In each figure, 1 is cross bar, and 2 is upper rack posts, and 3 is clamping screw, and 4 is handle, and 5 is stage clip, and 6 is lower fulcrum bar, and 7 is chute, and 8 is upper rack posts tooth bar, and 9 is lower fulcrum bar tooth bar, and 10 is handlebar stem, and 11 is bearing pin.

detailed description of the invention:

The design is illustrated below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, shown in Fig. 3, the horizontal bar of the design comprises cross bar 1, upper rack posts 2, lower fulcrum bar 6, stage clip 5, clamping screw 3, upper lower fulcrum bar distributes one thin one thick up and down, stage clip 5 is all equipped with in lower fulcrum bar, the lower end of upper rack posts insert lower fulcrum bar upper end and with the upper-end contact of stage clip 5, side tube wall near described lower fulcrum bar 6 upper end longitudinally has a microscler opening and chute 7, the lower fulcrum bar inwall of chute side is equally longitudinally fixedly connected with a tooth bar and lower fulcrum bar tooth bar 9, simultaneously on the outer tube wall of the corresponding upper rack posts 2 of tooth bar therewith, be also fixedly connected with a tooth bar and upper rack posts tooth bar 8, the teeth of upper lower fulcrum bar tooth bar are mutually meshing, as shown in Figure 4, on the opposite side tube wall of the just right lower fulcrum bar in the position with device tooth bar, device has a clamping screw 3, it can with tooth bar coordinate by regulate the upper lower fulcrum bar that puts in place meshing firmly together with, the security and stability of lower fulcrum bar on above-below direction and each horizontal direction in locking, the side tube wall of the upper rack posts bottom end vicinity in chute 7 is processed with a circular hole, be flexibly connected in the one columned handlebar stem 10 cutting out rectangular-shaped groove in circumferential wall pressed on ring penetrates upper rack posts circular hole by groove, by the tubular handle 4 being connected with a band-slot opening of bearing pin 11 activity on the handlebar stem exposed, as shown in Figure 5, because handlebar stem 10 and the connection of upper rack posts tube wall are movable connected modes, namely it in perpendicular shapely all the time with the tube wall of upper rack posts along the circumferential direction can rotate and cannot be separated from upper rack posts, so by bearing pin be flexibly connected with it and have the handle 4 of notch upper rack posts down operation in the chute of lower fulcrum bar can be driven to move (as shown in the upper figure in Fig. 5) by handlebar stem, after adjustment, then can become sagging shape (in as Fig. 5 by handle down again at handle half-twist angle simultaneously, shown in figure below), handle can be allowed by this to reclaim to reduce space hold.Like this, the adjustable horizontal bar of handle type of the design is just described, when needs are adjusted to lower state (shown in Fig. 2) by higher state (shown in Fig. 1), can first unscrew clamping screw 3, upper rack posts tooth bar 8 on upper rack posts just can depart from meshing with the lower fulcrum bar tooth bar 9 on lower fulcrum bar, in order to make this meshing disengaging with contact more smooth and easy, the shape of cross section of the tooth bar teeth of the design is corrugated, as shown in Figure 4, so just effectively avoid colluding with or meshing problem not in place of teeth, force is pressed 4 times by handle, cross bar can synchronously move down together with two upper rack posts, until just clamping screw 3 can be screwed after the height needed, recover whole horizontal bar in conjunction with resistance to overturning, meet the needs of motion, otherwise, contrary operation and adjustable height, the suitable elastic force of stage clip then can to upper rack posts appear on the stage and under be pulled up to power-assisted and supporting role.Horizontal bar height of the present invention is adjustable, and the people's body-building having adapted to differing heights uses.
