Additionally, all embodiments can be used in combination with each other.

[0031] Please refer to Figures 1 to 6 , the present invention provides a technical solution:

[0032] Embodiment 1

[0033] A multifunctional fitness dragon pillar, comprising: a vertical column 1, a load-bearing frame, and a connecting slider 9.

[0034] Specifically, the load-bearing frame includes a sliding sleeve 4, an L-shaped bracket 5 and a first load-bearing rod 6. The first load-bearing rod 6 is fixed to the middle of the sliding sleeve 4. Two L-shaped brackets 5 are provided and are symmetrically distributed on both sides of the first load-bearing rod 6. The L-shaped bracket 5 is fixedly connected to the sliding sleeve 4. The front ends of the L-shaped bracket 5 and the first load-bearing rod 6 are fixedly provided with a limited position protrusion 7, such as Figure 3 and Figure 5 As shown, when the handle bar 8 is placed on the first load-bearing bar 6 and the upper side of the L-shaped bracket 5, the first load-bearing bar 6 is used to bear the main weight of the handle bar 8, and the L-shaped bracket 5 can mainly prevent the handle bar 8 from tilting, ensuring the stable position of the handle bar 8;

[0035] Secondly, three connecting sliders 9 are provided and are respectively installed at the front ends of the first load-bearing rod 6 and the two L-shaped brackets 5. The surface of the connecting slider 9 is provided with a plug hole 10. The middle part of the inner side wall of the plug hole 10 is provided with a rotating slide groove 11 for the limit protrusion 7 to rotate and slide, and a translation slide groove 12 for the limit protrusion 7 to translate and slide. The translation slide groove 12 is connected with the rotating slide groove 11, as shown in FIG. Figure 5 and Figure 6 As shown, when the first load-bearing rod 6 is connected to the connecting slider 9, the connecting slider 9 first approaches the first load-bearing rod 6 and ensures that the translational slide groove 12 corresponds to the limiting protrusion 7, until the limiting protrusion 7 passes through the translational slide groove 12 and enters the rotating slide groove 11. At this time, the connecting slider 9 is rotated to stagger the limiting protrusion 7 and the translational slide groove 12, and the connecting slider 9 can be kept relatively fixed with the first load-bearing rod 6 in the length direction of the first load-bearing rod 6, and the connection between the L-shaped bracket 5 and the connecting slider 9 is the same as above, so the three connecting sliders 9 can be stably installed at the front end of the load-bearing frame and will not easily detach from the load-bearing frame.

[0036] Embodiment 2

[0037] On the basis of the first embodiment, in order to prevent the connecting slider 9 from rotating, the present application also has a handle rod 8 arranged at the front end of the load-bearing frame, and a handle plug hole 13 which is perpendicular to and offset from the plug hole 10 is opened on the surface of the connecting slider 9, the handle rod 8 and the handle plug hole 13 are movably connected through and connected, and are used to connect the handle rod 8 and the connecting slider 9, and because the handle plug hole 13 and the plug hole 10 are perpendicular to each other, after the connecting slider 9 is connected to the handle rod 8, the connecting slider 9 cannot rotate, so that it can be stably fixed on the end of the first load-bearing rod 6 (and the L-shaped bracket 5), a stepped cone 81 is fixedly arranged on the surface of the handle rod 8, and a sponge layer 82 is arranged at the end of the handle rod 8, and the diameter of the stepped cone 81 is larger than the inner diameter of the handle plug hole 13, so as to prevent the connecting slider 9 from sliding along its own length direction, and the setting of the sponge layer 82 improves the comfort of the user when grasping.

[0038] Embodiment 3

[0039] On the basis of the second embodiment, in order to connect the connecting slider 9 and the handle rod 8, the present application further has an installation notch 14 formed on the upper surface of the connecting slider 9. The installation notch 14 is located on one side of the handle insertion hole 13 and communicates with the handle insertion hole 13. The installation notch 14 is provided for the installation or disassembly of the handle rod 8 and the connecting slider 9. An anti-deviation boss 15 is fixedly provided at the corner of the bottom of the installation notch 14. The upper end surface of the anti-deviation boss 15 is at the same height as the axis of the handle insertion hole 13. The anti-deviation boss 15 is provided to prevent the connecting slider 9 from moving horizontally and separating from the handle insertion hole 13.

[0040] Embodiment Four

[0041] On the basis of the third embodiment, in order to fix the first load-bearing rod 6 (and the L-shaped bracket 5), the present application further has a chamfer 16 provided at the open end of the insertion hole 10 to facilitate the insertion of the first load-bearing rod 6 into the insertion hole 10. Three positioning sleeves 17 are fixedly connected to the surface of the sliding sleeve 4. The first load-bearing rod 6 and two L-shaped brackets 5 are respectively movably inserted into the three positioning sleeves 17. A positioning hole 18 is formed on the surface of the positioning sleeve 17. A fastening bolt is inserted into the inner cavity of the positioning hole 18. After the fastening bolt is tightened, it can be inserted into the rear end of the first load-bearing rod 6 (and the L-shaped bracket 5), thereby fixing the first load-bearing rod 6 (and the L-shaped bracket 5) to the positioning sleeve 17.

[0042] Embodiment Five

[0043] On the basis of the fourth embodiment, in order to connect the sliding sleeve 4 and the column 1, the present application further has flat cutting grooves 2 formed on both sides of the surface of the column 1. A mating sliding hole 19 adapted to the column 1 is formed inside the sliding sleeve 4. The sliding sleeve 4 is matched with the column 1 through the mating sliding hole 19. The sliding sleeve 4 can only slide up and down along the length direction of the column 1 and cannot rotate. A plurality of positioning insertion holes 3 are formed through the surface of the flat cutting groove 2 at equal intervals. A bearing bracket 22 inserted into the positioning insertion holes 3 is provided on the outer side of the sliding sleeve 4. The bearing bracket 22 is used to fix the sliding sleeve 4 outside the column 1.

[0044] Embodiment Six

[0045] On the basis of the fifth embodiment, in order to position the sliding sleeve 4, two bearing brackets 22 of the present application are provided and symmetrically distributed. A fixing ring 21 is provided at the connection of the two bearing brackets 22. An insertion interface 20 is formed on the surface of the sliding sleeve 4. The end of the bearing bracket 22 sequentially passes through the insertion interface 20 and the positioning insertion hole 3 movably and fixes the sliding sleeve 4 to the column 1. The bearing bracket 22 is used to position the sliding sleeve 4 to ensure that the sliding sleeve 4 can be fixed outside the column 1 and will not slide up and down randomly.

[0046] Embodiment Seven

[0047] Based on Embodiment Six, in order to fix the load-bearing bracket 22, the present application further has a fastening screw 23 movably penetrating through the middle of the fixing ring 21. There are at least three insertion openings 20. One end of the fastening screw 23 passes through the insertion opening 20 in the middle of the sliding sleeve 4 and is threadedly inserted into the inner wall of the mating sliding hole 19. The other end of the fastening screw 23 is provided with a knob 24. The diameter of the fastening screw 23 is slightly smaller than the inner diameter of the insertion opening 20. Therefore, when the sliding sleeve 4 is forced to move downward, only the load-bearing bracket 22 bears the force and positions the sliding sleeve 4, and the fastening screw 23 does not bear the force, so as to avoid the fastening screw 23 being bent by the force. The fastening screw 23 is only used to prevent the load-bearing bracket 22 from sliding and detaching from the insertion opening 20.

[0048] Embodiment Eight

[0049] Based on Embodiment Seven, in order to ensure that the column 1 stably remains vertical, the present application further has connecting threads 25 provided at both ends of the column 1. Connecting nuts 26 are sleeved on the outer sides of both ends of the column 1. The end of the connecting nut 26 is fixedly connected with a base 27. A connecting platform 28 is fixedly connected to the side of the base 27. A reinforcing plate 29 is fixedly arranged between the connecting nut 26 and the base 27. The connecting platform 28 is fixed to the external gantry by bolts to ensure that the column 1 can stably remain vertical. At the same time, the connecting nut 26 and the column 1 can rotate relative to each other, and the distance between the two connecting nuts 26 can be adjusted.

[0050] Embodiment Nine

[0051] Based on Embodiment Eight, in order to increase the functionality of the present device, there are two load-bearing frames in the present application, and the first load-bearing rod 6 on the other load-bearing frame is replaced with a second load-bearing rod 30 with a smaller length. The second load-bearing rod 30 is fixedly inserted into the positioning sleeve 17. A connecting ring 31 for connecting a tension rope is installed at the end of the second load-bearing rod 30. As Figure 1 shown, after the tension rope is connected to the connecting ring 31, it can be used by the user for training in other projects.

[0052] Embodiment Ten

[0053] Based on Embodiment Nine, in order to further increase the functionality of the present device, the L-shaped bracket 5 on the other load-bearing frame is rotatably connected to the positioning sleeve 17 through a bearing. The end length of the L-shaped bracket 5 on the other load-bearing frame is greater than the length of the second load-bearing rod 30. That is to say, the L-shaped bracket 5 on the other load-bearing frame and the positioning sleeve 17 can rotate relative to each other. By installing the handle rod 8 together with the connecting slider 9 on the other load-bearing frame, the user can perform barbell clean and jerk and weighted squat training on the other load-bearing frame.

[0054] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
