The vertical sliding sleeve 57 is fixedly connected to the sliding frame 8 through a connecting seat 63. An A-rod 50 is commonly mounted on the horizontal connecting rod 56 on the columns 2 on the left and right sides of the frame body. The A-rod 50 and the horizontal connecting rod 56 are connected through a rotating frame 5, and the rotating frame 5 can realize three-dimensional swing; a gate handle 51 is provided on the A-rod 50, and the gate handle 51 is connected to the inside of the sliding frame 8 through a gate line. A telescopic rod device 7 is provided inside the sliding frame 8, and the telescopic rod 73 is telescopically inserted in the positioning hole 21 through the stretching of the gate line to realize the positioning of the sliding frame 8.

[0026] Through the above structural arrangement, at least two brake handles 51 are arranged on the Olympic bar 50, and the left and right ends of the Olympic bar 50 extend to the outside of the column 1 and form a barbell hanging part 52, through which the external load can be fixed.

[0027] The above-mentioned Austrian rod 50 and horizontal connecting rod 56 are connected and fixed by the rotating frame 5. The purpose of setting the rotating frame 5 is to achieve three-dimensional swing. This function is achieved by the following structure:

[0028] The rotating frame is composed of three parts, namely, a top rotating sleeve 53 slidably connected to the Austrian rod 50, a bottom sliding sleeve 55 slidably connected to the connecting rod 56, and a vertical rotating sleeve 54. The top rotating sleeve 53 and the bottom sliding sleeve 55 are arranged at a right angle of 90 degrees; the top rotating sleeve 53 and the bottom sliding sleeve 55 are connected by a vertical rod, and a vertical rotating sleeve 54 is arranged between the vertical rod and the top rotating sleeve 53 or the bottom sliding sleeve 22. Through the above structural arrangement, the Austrian rod 50 can slide and rotate in place on the connecting rod 56, and can also swing horizontally on the bottom sliding sleeve 55 and rotate in place on the top rotating sleeve 53.

[0029] The reason why the multi-directional training device does not fall during exercise is that the key design lies in the positioning and matching of the telescopic rod device and the positioning hole 21; Figure 8 and Fig. 9 As shown, Figure 8The telescopic rod device is fixed inside the sliding frame 8, which includes an outer tube stopper 71 fixed on the sliding frame 8, the outer tube stopper 71 and the pull rod 72 are connected to each other, the pull rod 72 is connected and fixed to the swing shaft 78, the swing shaft 78 is hinged to two pulling rods 77 respectively, the pulling rod 77 is connected to the telescopic rod 73, the telescopic rod 73 passes through the telescopic sleeve 74 and exposes a positioning protrusion 76 at the outer end of the telescopic sleeve 74, and the telescopic rod 73 is provided with a reset spring 75 inside the telescopic sleeve 74, and the horizontal reset movement of the telescopic rod 73 is realized by the reset spring 75, such as Figure 8 As shown, when the steel cable is pulled through the brake handle 51, the steel cable pulls the pull rod 72 to drive the swing shaft 78 to rotate, and the swing shaft 78 drives the pulling rod 77 to swing to pull the telescopic rod 73. When the telescopic rod 73 is retracted, the positioning protrusion 76 disengages from the positioning hole 21, and the sliding frame 8 can move vertically on the guide column 10. When the brake handle 51 is released, under the action of the reset spring 75, the positioning protrusion 76 on the telescopic rod 73 extends out, and cooperates with the positioning hole to realize the positioning of the entire sliding frame 8.

[0030] Furthermore, the device is provided with a guide wheel 4 at the top of each column 2, and a fixing rod 57 is provided on the sliding frame 8. After the fixing rod 57 is connected to the steel cable, it passes over the guide wheel 4 and enters the interior of the column 2. A counterweight block is provided inside the column 2. Through this design, when the user adjusts the height of the sliding frame 8, sliding operation with no resistance or low resistance can be achieved under the action of the counterweight block provided inside the column 2.

[0031] Furthermore, below the sliding frame 8, a positioning frame 6 is provided on the columns on the left and right sides, respectively. A positioning sleeve 61 is fixedly provided on the positioning frame 6 through a connecting seat 63, and is slidably matched with the column 2. A telescopic rod device 7 is provided inside the positioning frame 6. The telescopic rod device 7 is controlled to be telescoped in the positioning hole 21 by the extension of the brake wire pulling device 62 on the positioning frame 6 to achieve the positioning of the positioning frame 6; a buffer pad 11 is provided on the column between the positioning frame 6 and the sliding frame 8. Through the above structural setting, the positioning frame 6 can block the sliding frame 8 vertically. When the position of the sliding frame 8 is set, the positioning frame 6 is moved to the bottom of the sliding frame 8, so as to achieve the effective positioning of the sliding frame.

[0032] The telescopic rod device 7 fixed inside the positioning frame 6 can be Fig. 9The structure shown is driven, and a corresponding brake wire pulling device 62 is provided at each positioning protrusion 76. The brake wire is controlled by the pulling drive of the brake wire pulling device 62. An outer tube stopper 71 is fixed inside the positioning frame 6. The outer tube stopper 71 and the pull rod 72 are connected together. The pull rod 72 is connected to the telescopic rod 73. The telescopic rod 73 passes through the telescopic sleeve 74 and exposes the positioning protrusion 76 at the outer end of the telescopic sleeve 74. The telescopic rod 73 is provided with a reset spring 75 inside the telescopic sleeve 74. The reset spring 75 is used to realize the horizontal reset movement of the telescopic rod 73, so that the height position of the positioning frame 6 can be adjusted by this structure.

[0033] Through the above design, the present invention sets a positioning plate 20 on the column 2, sets a guide column 10 near the column, sets a sliding frame 8 on the guide column 10 to set up the Olympic rod 50, and the Olympic rod 50 and the sliding frame 8 are connected by a rotating frame 5, and the rotating frame 5 can realize the three-dimensional swing of the Olympic rod 50 and the sliding frame 8; a guide wheel 4 is set on the top of each column 2, and this device connects the counterweight inside the column 2 and the sliding frame 8, which can reduce the resistance when the sliding frame 8 is lifted or lowered; for safer use, this device is provided with a positioning frame 6 directly below each sliding frame, and the positioning frame 6 is blocked to prevent the sliding frame 8 from falling when the Olympic rod is loaded, thereby eliminating the safety hazard of the user, and is an ideal multi-directional training device.
