Specific embodiment

As shown in Fig. 1 ~ 3, the utility model is mainly made up of the part such as base tube 1, crossbeam, standpipe 8 and railing.

Base tube 1 is square straight tube, and its front end is connection end, and central siphon is vertically installed with the top surface of the front end of base tube 1 2.As shown in figure 3, central siphon 2 is pipe, the pilot hole 4 of circumferential bar hole 3 and axial direction, bar hole are offered on its tube side wall Central angle corresponding to 3 is 90 °, the upper edge for opening to central siphon 2 suitable for reading of pilot hole 4, and its lower mouth is communicated with bar hole 3, is used for Assembling crossbeam.

Crossbeam includes two sleeve pipes 5 being vertically arranged and the cross bar 6 being connected between two sleeve pipes 5, and sleeve pipe 5 is circular short Pipe, it is set on central siphon 2, the height of the height more than central siphon 2 of sleeve pipe 5, and interior spiral shell is formed with the madial wall at the top of sleeve pipe 5 Line.As shown in figure 3, being horizontally arranged with spacer pin 7 on the madial wall of sleeve pipe 5, spacer pin 7 is located at a diameter line of sleeve pipe 5 On, its one end is fixed on the madial wall of sleeve pipe 5, and the other end is hanging setting.

When crossbeam and base tube 1 is assembled, sleeve pipe 5 is placed in the top of central siphon 2, spacer pin 7 is directed at pilot hole 4（Such as Fig. 3）, moving down sleeve pipe 5, spacer pin 7 is moved down in pilot hole 4, until spacer pin 7 enters in bar hole 3, now left/right rotation Dynamic base tube 1, is capable of achieving the opening of base tube 1 and folds, and the folded state of base tube 1 is as shown in Figure 2.

Standpipe 8 is circular straighttube, and its bottom is plugged on the top of sleeve pipe 5, outer spiral shell is formed with the lateral wall of the bottom of standpipe 8 Screw-internal thread fit at the top of line, and external screw thread and sleeve pipe 5, so as to standpipe be connected with casing threads.In the top tube wall of standpipe 8 On be provided with positioning knob 9, and structure is specially：Location hole is offered on the top tube wall of standpipe 8, on location hole periphery Nut is welded with tube wall, the screw of the nut is just right with location hole, and the screw rod on positioning knob 9 is screwed in screw, and spiral shell The end of bar may pass through location hole into the inside of standpipe 8.

Railing includes the horizontal body of rod 10 and is connected to the lower knee body 11 at the two ends of the horizontal body of rod 10, wrapped on the horizontal body of rod 10 Foam protective set is covered with, is used to protect the physical safety of trainer, prevent injury of colliding with, the bottom of lower knee body 11 is plugged on vertical The top of pipe 8, and fixed with standpipe 8 by positioning knob 9.

Setting for railing highly can insert the depth in standpipe 8 adjust by the lower knee body 11 of adjustment, its adjusting method For：Rotational positioning knob 9, in making the screw rod retracted screw of positioning knob 9, then on pull out（Or push）Railing, is adjusted Whole to required height, then positioning knob 9 is rotated backward, its screw rod end is held out against on lower knee body 11, by lower knee body 11 are fixed, it is ensured that it will not be shifted in the training process.

The utility model is made using lightweight stainless steel material, and railing, crossbeam etc. are hollow tube, with mitigate across The weight on column, reduces its impulsive force that can bear, even if can also be translated into forward by weaker impulsive force, so as to ensure training The safety of person, it is to avoid damage.
