The rack-type adjustable horizontal bar is a horizontal bar mainly used in sports equipment.

Description

Rack-and-pinion is adjustable horizontal bar

Technical field

The invention belongs to sports apparatus field, specifically refer to the adjustable horizontal bar of a kind of rack-and-pinion.

Background technology

Horizontal bar is a kind of important physical training utensil, extensively arrange in the large primary school that teenager concentrates, in addition along with people are to the attention gradually of body building, the also common distribution in places such as residential blocks, it is generally made up of two poles cross bar, what extensively see is all that height can not regulate, and the height two groups that is set to had connects all-in-one-piece mutually, though this facilitates much will take larger space, place; In actual life, people need a kind of horizontal bar that can just regulate to use to facilitate people's body-building of differing heights.

Summary of the invention

Object of the present invention is the new adjustable horizontal bar of technical scheme rack-and-pinion providing a kind of horizontal bar, and it can eliminate the deficiency of said apparatus.

Technical scheme of the present invention realizes like this, it comprises cross bar, upper rack posts, lower fulcrum bar, clamping screw, on one section of inner tubal wall of described upper rack posts bottom, downward all affixed one section of tooth bar is until the bottom end vicinity of lower fulcrum bar, the tube wall of the relative left and right sides of this section of upper rack posts on the right also has one section of opening and the rocking arm opening of above-below direction, a rocking arm is through on the tube wall of rocking arm shedding motion lower fulcrum bar on the right, on rocker arm shaft, device has the rocker gear mutually meshing with tooth bar and the stopping gear mutually meshing with the stop tooth be arranged on outside lower fulcrum bar on tube wall, two lower fulcrum bars connect at lower fulcrum bar lower end by the crossbeam of one tubulose, and a shaft-like ratch is through crossbeam and be connected on the outside tube wall of two lower fulcrum bars by its two ends activity, and at the position of the close tooth bar of ratch, all device has mutually meshing ratch gear.

The invention has the beneficial effects as follows and horizontal bar height can be allowed adjustable, use with the people's body-building adapting to differing heights.

accompanying drawing illustrates:

Fig. 1 is that the design illustrates the front view (higher state) of horizontal bar.

Fig. 2 is the front view of the horizontal bar being in the state of turning down.

Fig. 3 is that (higher state, containing rocking arm, stopping gear, only for the right side view of horizontal bar

The magnified detail view of the connectors such as dynamic tooth, ratch, ratch gear).

Fig. 4 is the amplification front elevation of rocking arm, rocker arm shaft, rocker gear, stopping gear.

In each figure, 1 is cross bar, and 2 is upper rack posts, and 3 is tooth bar, and 4 is clamping screw, and 5 is rocking arm, and 6 is rocker gear, and 7 is rocker arm shaft, and 8 is stopping gear, and 9 is crossbeam, and 10 is ratch, and 11 is stop tooth, and 12 is lower fulcrum bar, and 13 is ratch gear, and 14 is rocking arm opening.

detailed description of the invention:

The design is illustrated below in conjunction with accompanying drawing.

As shown in Figure 1, Figure 2, Figure 3 shows, the horizontal bar of the design comprises cross bar 1 and coupled left and right upper rack posts 2, left and right lower fulcrum bar 12, the clamping screw 4 on top, it is one thin one thick that upper and lower pole is all that tubulose distributes up and down, one section, the upper end of lower fulcrum bar is inserted in the lower end of upper rack posts, on tube wall near the upper end that clamping screw is fixed on lower fulcrum bar, highly regulate put in place after upper lower fulcrum bar can be connected and fixed locking by it, play the safety effect that assistant reinforcement is firm, also comprise the crossbeam 9 being in bottom, two lower fulcrum bars connect at the lower end of lower fulcrum bar 12 by it, all affixed one section of tooth bar 3 in above-below direction on one section of two upper rack posts bottoms inner tubal wall rearward, and tooth bar lengthens downwards until the bottom end vicinity of lower fulcrum bar 12, as Fig. 1, shown in Fig. 3, the tube wall of the relative left and right sides of this section of upper rack posts 2 is on the right processed with one section of opening and the rocking arm opening 14 of above-below direction, Rocker arm 5 outside device lower fulcrum bar on the right on tube wall is through rocking arm opening 14, on the rocker arm shaft 7 of rocking arm, device has the rocker gear 6 mutually meshing with tooth bar 3 and the stopping gear 8 mutually meshing with the stop tooth 11 be arranged on outside lower fulcrum bar 12 on tube wall, as Fig. 2, Fig. 3, shown in Fig. 4, stop tooth 11 is by the lower fulcrum bar tube wall being connected near rocking arm of its axle activity, it can the meshing stopping gear firmly regulated on complete rocking arm, fix the relative position of lower fulcrum bar, aforesaid rocking arm and on attaching parts, rocking arm opening is only arranged on the upper rack posts of side, the right, on lower fulcrum bar, side, the left side is not arranged, one shaft-like ratch 10 is connected on the outside tube wall of two lower fulcrum bars through crossbeam 9 and by its two ends activity, there is a ratch gear 13 mutually meshing with tooth bar at the position of the close tooth bar 3 simultaneously on ratch 10 all device, and about ratch gear, each one is meshing with left and right tooth bar respectively.Like this, the adjustable horizontal bar of rack-and-pinion 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 4, counterclockwise Rocker arm 5 is shaken after separating stop tooth 11 again, under the meshing drive of rocker gear 6, tooth bar 3 can move down by related upper rack posts, synchronous tooth bar and the upper rack posts being tooth bar and also by the transmission of ratch gear and ratch, this mobile trend can being passed to left side therewith, namely the height adjustment operation completing horizontal bar that just can be synchronous need only be operated in side, turn down downwards after adjustment puts in place and stop tooth can be returned stop position, fix the relative position of lower fulcrum bar above-below direction, operate the position that horizontal direction fixed by clamping screw again, just can normally employ, otherwise, contrary operation just can complete and heighten adjustment, too raise for preventing upper rack posts, the Working position of rocking arm opening 14 should be suitable, namely its bottom should upper move touch rocker arm shaft time stop live in pole continuation on move, it is meshing that the lower end of this hour rack would not depart from ratch gear, in addition rocking arm, ratch and lower fulcrum bar be flexibly connected position can device upper bearing (metal) to alleviate friction, whole for crossbeam position should be embedded in underground when device horizontal bar.The horizontal bar one people side of the design can complete height and regulate, simple and convenient, can meet the body-building needs of people in the use of reality greatly.
