Specific embodiments

[0025] Referring to the figure shown, the present utility model discloses a foldable new core bed, which designs an adjustable cross beam 1, and an adjustable sliding plate 4 is arranged on the cross beam 1 and the angle of the sliding plate can be adjusted. The present utility model combines Pilates fitness with lying and sitting traction equipment, and can comprehensively train various parts of the body.

[0026] Embodiment 1:

[0027] A foldable new core bed includes a cross beam 1, and the cross beam 1 is fixed to an extension beam 2 through a hinge assembly. For a more specific structure, a hinge assembly and a torsion spring assembly are arranged at the joint of the cross beam 1 and the extension beam 2. The hinge assembly includes a cross beam hinge 13 on the cross beam 1 and an extension beam hinge 22 on the extension beam 2, and the two are fixed through a connecting shaft; under the action of an external force, the folding and storage of the cross beam hinge 13 and the extension beam hinge 22 can be realized.

[0028] An end connection sleeve 23 is provided at the end of the extension beam 2. A protective locking part 25 is hinged and fixed on the end connection sleeve 23 through a locking shaft 24. On the extension beam 2, a force application handle 27 is further provided on the end connection sleeve 23. The force application handles 27 are two symmetrically arranged left and right, which can be grasped and applied force by the trainer on both the left and right sides at the same time.

[0029] The protective locking part 25 is provided in a matching manner with the vertical column 7. A plurality of positioning holes 75 are provided on the column body 74 of the vertical column 7. A sliding frame 26 is provided on the protective locking part 25 and arranged around the column body 74. A locking torsion spring 28 is provided on the sliding frame 26. An elastic positioning plate 29 is fixed on the locking torsion spring 28 and is arranged in cooperation with the positioning holes 75.

[0030] As Figure 7 shown, in this embodiment, in order to realize the vertical adjustment of the protective locking part 25 on the vertical column 7, a pull rod 6 is specifically arranged in the top cover 73 at the top of the vertical column 7. A positioning plate connecting rod 612 is arranged on the pull rod 6 and is connected to the elastic positioning plate 29. Through the above structural arrangement, the user can drive the pull rod 6 on one side of the top cover 73 to drive the positioning plate connecting rod 612 to swing back and forth, so as to realize the movement of the elastic positioning plate 29 inside and outside a plurality of positioning holes 75 and then realize position locking. When the user adjusts the inclination angle of the cross beam 1, the above structure can realize stable locking and ensure the safety of the user in various body position training states.

[0031] Furthermore, a base 71 is provided at the bottom of the vertical column 7. An inclined beam 5 is hinged on the base 71 or the vertical column 7. In this embodiment, the bottom end of the inclined beam 5 is hinged on the base 71, the top end of the inclined beam 5 is hinged on the bottom surface of the cross beam 1, and a hinge cylinder 54 is provided at the top of the inclined beam 5. A folding torsion spring 55 is also provided in cooperation with the hinge cylinder 54. When the cross beam 1 and the extension beam 2 are folded, the folding torsion spring 55 can be used as a resistance support structure in the horizontal state to prevent the cross beam 1 and the extension beam 2 from folding disorderly and maintain the stability of their horizontal combination through the folding torsion spring 55. When the user performs folding and storage, the cross beam 1 and the extension beam 2 can be folded only by overcoming the folding torsion spring 55. Lower hinge points 51 and upper hinge points 52 are respectively provided on the inclined beam 5 and the bottom of the extension beam 2. The upper hinge point 52 and the lower hinge point 51 are supported by an auxiliary cylinder 53. By providing the auxiliary cylinder 53, the resistance of the folding torsion spring 55 can be overcome when the cross beam 1 and the extension beam 2 are folded. The function of providing the auxiliary cylinder 53 is also that no spring is required, and the resistance is increased by adjusting the angle, and it can be adjusted arbitrarily from 0 to 45 degrees.

[0032] One end of the cross beam 1 of the utility model is fixed with a force application pedal 31. The force application pedal 31 is fixed on the pedal fixing bracket 3. The pedal fixing bracket 3 is fixed at the end of the cross beam 1 through a socket 32. A pin 33 is arranged on the socket 32 and is inserted and matched with the positioning hole on the cross beam 1. The force application pedal 31 with such a structure can be quickly disassembled and assembled, facilitating the expansion of various functions of the foldable new core bed.

[0033] The utility model is provided with guide rails 21 on the cross beam 1 and the extension beam 2. A sliding plate 4 is arranged on the guide rails 21. A sliding bracket 41 and a panel 46 are arranged at the bottom of the sliding plate 4. A support rod 43 is arranged at the bottom of the panel 46. A positioning groove 45 is arranged inside the sliding bracket 41 and is inserted and matched with the positioning rod 44 at the bottom end of the support rod 43 to realize the support after the sliding plate 4 is lifted.

[0034] In summary, the utility model can realize the adjustment of the relative angle between the cross beam 1, the extension beam 2 and the ground, can realize the sliding of the sliding plate 4 on the cross beam 1 and the extension beam 2, can realize the expansion of functions similar to those of a Pilates bed by means of the sliding plate 4, and can realize the stretching or tensile training of various muscle groups of the trainer in the lying, sitting, standing and kneeling postures, so as to realize the training of the arms, abdomen, waist, buttocks and legs. The equipment is simple to assemble, convenient to adjust the angle and convenient to store, and is an ideal foldable new core bed.
