DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments. Example

[0026] like Figure 1-7As shown, the height-adjustable barbell rack provided by the utility model comprises: a bottom plate 1, two supporting columns are installed on the bottom plate 1, and the supporting columns include a fixed tube 2 and a lifting tube 3, the fixed tube 2 is fixedly installed at the bottom of the bottom plate 1, and the lifting tube 3 is movably installed inside the fixed tube 2, and the lifting tube 3 can be lifted and lowered to adjust the height of the supporting column, and a rack 4 is fixedly installed at the bottom of the lifting tube 3, and the bottom of the rack 4 contacts the bottom plate 1 and is located inside the fixed tube 2, and a rotating shaft 5 is rotatably installed inside the fixed tube 2. , a gear 6 is fixedly mounted on the rotating shaft 5, and the gear 6 meshes with the rack 4. A fixed seat 7 is fixedly mounted on one end of the rotating shaft 5, and the same connecting shaft 8 is installed on the two fixing seats 7 by bolts. At this time, when one rotating shaft 5 is rotated, the other rotating shaft 5 can be driven to rotate, so that the two gears 6 rotate synchronously. The gear 6 rotates to move the rack 4 upward, and then the two lifting tubes 3 can be lifted synchronously. A self-locking motor 9 is fixedly mounted on one side of one of the fixed tubes 2, and the output shaft of the self-locking motor 9 is connected to the corresponding rotating shaft 5. When in use, when it is necessary to adjust the height of the barbell rack upward, the self-locking motor 9 is started first to rotate one of the rotating shafts 5, and the rotating shaft 5 drives the other rotating shaft 5 to rotate through the connecting shaft 8, so that the two gears 6 rotate at the same time, and the two gears 6 rotate to move the rack 4 and the lifting tube 3 upward until the lifting tube 3 reaches the specified height, and then the self-locking motor 9 can be stopped. In this embodiment, by starting the self-locking motor 9, the two lifting tubes 3 can be raised and lowered synchronously, which makes the operation more convenient. At the same time, during operation, there is no need to remove the barbell, etc., and the operation is simple. The connecting shaft 8 is detachable and can be removed when not in use to avoid inconvenience to the user during exercise. Example

[0027] like Figure 5As shown, a quick-connect structure is provided at one end of one of the rotating shafts 5, and the quick-connect structure can realize the quick connection between the rotating shaft 5 and the self-locking motor 9. The quick-connect structure includes a first rectangular block 10 fixedly mounted on the rotating shaft 5, a magnet 11 is fixedly mounted on one end of the first rectangular block 10, and a plurality of jacks 12 are provided on the magnet 11. A second rectangular block 13 is fixedly mounted on the output shaft of the self-locking motor 9, and a movable sleeve 14 is slidably sleeved on the second rectangular block 13. The material of the movable sleeve 14 is iron, and the movable sleeve 14 is fixedly mounted at one end close to the magnet 11. A plurality of plug rods 15 are provided, and the plug rods 15 are adapted to the socket 12. When the self-locking motor 9 is needed to drive the rotating shaft 5, the movable sleeve 14 is moved first, so that the plug rod 15 is inserted into the socket 12, and the magnet 11 attracts the movable sleeve 14. At this time, the self-locking motor 9 is started, and the second rectangular block 13 will rotate. The second rectangular block 13 drives the first rectangular block 10 to rotate through the movable sleeve 14, the plug rod 15 and the magnet 11, and the first rectangular block 10 drives the rotating shaft 5 to rotate. When the self-locking motor 9 is not needed to drive the rotating shaft 5 to rotate, the plug rod 15 and the socket 12 need to be kept in a separated state. Example

[0028] like Figure 6-7 As shown, a crank 16 is fixedly installed at one end of one of the rotating shafts 5. When the insertion rod 15 and the insertion hole 12 are in a separated state, the two rotating shafts 5 can be driven to rotate by turning the crank 16, thereby realizing the lifting and lowering of the two lifting tubes 3. An outer gear ring 17 is fixedly installed at one end of the rotating shaft 5. The outer gear ring 17 rotates with the rotating shaft 5. An inner gear ring 18 adapted to the outer gear ring 17 is provided on one side of the fixed tube 2. A plurality of limiting rods 19 are fixedly installed on one side of the fixed tube 2. The plurality of limiting rods 19 all penetrate the inner gear ring 18 and are slidably connected to the inner gear ring 18. The inner gear ring 18 can move on multiple limit rods 19 to achieve engagement or separation with the outer gear ring 17. During use, when the motor 9 is damaged or the power is cut off, if it is necessary to adjust the height of the barbell rack, at this time, the insertion rod 15 and the insertion hole 12 must be separated at the same time, and the inner gear ring 18 and the outer gear ring 17 are separated, and then the crank 16 is turned to rotate the two rotating shafts 5, thereby lifting the two lifting tubes 3. In this embodiment, when the motor 9 is damaged or the power is cut off, the lifting and lowering of the lifting tube 3 is achieved by turning the crank 16, and the driving mode is diversified and more adaptable.

[0029] Furthermore, a limiting plate 20 is fixedly mounted on one end of the limiting rod 19 away from the fixing tube 2 , and the limiting plate 20 has a blocking effect on the inner gear ring 18 so that the inner gear ring 18 will not be separated from the limiting rod 19 . Example

[0030] like Figure 1 As shown, the lifting tube 3 is provided with a plurality of adjustment holes 24 , and the fixing tube 2 is penetrated by a fixing pin 25 , which penetrates the adjustment holes 24 . The fixing pin 25 cooperates with the adjustment holes 24 to fix the lifting tube 3 . Example

[0031] like Figure 3 As shown, side panels 21 are fixedly installed on both sides of the bottom plate 1, and a threaded rod 22 runs through the side panel 21, and the threaded rod 22 is threadedly connected to the side panel 21, and the bottom end of the threaded rod 22 is fixedly connected to a suction cup 23, and the suction cup 23 can be adsorbed on the wooden floor and the tile floor to prevent the device from shaking and being unstable when in use. When in use, the threaded rod 22 is rotated to drive the suction cup 23 to move downward until it fits with the ground. When not in use, the bottom of the suction cup 23 is tilted to separate the suction cup 23 from the ground, and the threaded rod 22 is rotated to drive the suction cup 23 to move upward to prevent the bottom of the suction cup 23 from rubbing back and forth with the ground when not in use to generate dust, reduce the adsorption force and make it difficult to maintain.

[0032] Working principle:

[0033] When the height of the barbell rack needs to be adjusted upward, the self-locking motor 9 is first started to rotate one of the rotating shafts 5, and the rotating shaft 5 drives the other rotating shaft 5 to rotate through the connecting shaft 8, so that the two gears 6 rotate at the same time. The rotation of the two gears 6 causes the rack 4 and the lifting tube 3 to move upward until the lifting tube 3 reaches the specified height, and then the self-locking motor 9 can be stopped. Conversely, when the height of the barbell rack needs to be lowered, the motor 9 can be started in the reverse direction;

[0034] When the motor 9 is damaged or the power is off, if the height of the barbell rack needs to be adjusted, the insertion rod 15 and the insertion hole 12 must be separated, and at the same time, the inner gear ring 18 and the outer gear ring 17 must be separated, and then the crank 16 is turned to rotate the two shafts 5, thereby raising and lowering the two lifting tubes 3.
