Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Example one

Referring to fig. 1-5 and 8, a barbell stand convenient for adjusting a balance weight comprises a lying plate 2, the lying plate 2 is placed on the ground through a base 1, one end of the lying plate 2 is an arc-shaped section, the other end of the lying plate 2 is a horizontal section, a sponge mat is arranged on the upper surface of the lying plate 2, and a headrest 19 is arranged on the upper side of the horizontal section of the lying plate 2.

Transmission case 3 is installed to the horizontal segment of service creeper 2, install motor 7 in the transmission case 3, slide rail 6 is all installed to service creeper 2 near the both sides of 3 one ends of transmission case, threaded rod 9 is installed to 6 internal rotations of slide rail, and slide rail 6 installs backup pad 10 through threaded rod 9 screw thread, as shown in fig. 4, backup pad 10 is located the inside one end of slide rail 6 and is "T" font structure, and backup pad 10 is located the inside one end of slide rail 6 and seted up with threaded rod 9 assorted screw hole.

One end of the threaded rod 9 extends into the transmission case 3, and a driving end of the motor 7 and one end of the two threaded rods 9, which are positioned in the transmission case 3, are jointly provided with a transmission belt mechanism 8; the transmission belt mechanism 8 comprises a transmission wheel and a transmission belt, the transmission wheel is installed at the driving end of the motor 7 and at one end of the threaded rod 9 extending into the transmission box 3, and the transmission wheel located at the driving end of the motor 7 is in transmission connection with the transmission wheel located at the end of the threaded rod 9 through the transmission belt.

The motor 7 collects a servo motor, forward and reverse rotation control is performed by the aid of a driver and a single chip microcomputer, forward and reverse rotation of the motor 7 can be controlled by the aid of the transmission belt mechanism 8, and the threaded rod 9 can drive the supporting plate 10 to move repeatedly in the sliding track 6 when rotating.

Weight boxes 4 are installed on the upper sides of the two supporting plates 10, vertical slotted holes 11 are formed in the front side and the rear side of the two weight boxes 4 in a penetrating mode, the two weight boxes 4 are slidably installed with barbell rods 5 through the vertical slotted holes 11, the diameter of each barbell rod 5 is slightly smaller than the width of each vertical slotted hole 11, the two ends of each barbell rod 5 extend to the outer sides of the two weight boxes 4 respectively, and limit knobs 16 are installed on the threads.

The barbell bar 5 traverses both weight boxes 4 simultaneously and allows a stable mounting when the limit knob 16 is tightened. After the limit knob 16 is rotated to the end of the barbell bar 5, a gap is still left between the inner wall of the limit knob 16 and the outer wall of the weight box 4, that is, the limit knob 16 does not contact with the weight box 4, thereby reducing unnecessary resistance generated when the barbell bar 5 is lifted.

A plurality of balancing weights 13 are movably mounted inside the two weight boxes 4 through U-shaped sliding rails 14, the balancing weights 13 are located on the upper side of the barbell rod 5, arc-shaped holes 17 are formed in the centers of the top walls of the balancing weights 13, and the diameters of the arc-shaped holes 17 are slightly larger than the diameter of the barbell rod 5. The heights of the lower sides of the counter weights 13 in the same weight box 4 are different, and the heights of the lower sides of the U-shaped slide rails 14 in the same weight box 4 are different.

The bottom of the U-shaped slide rail 14 is closed, and can generate a limiting effect on the counterweight block 13, thereby limiting the lowest position where the counterweight block 13 can fall.

When a trainer pushes the barbell bar 5, the barbell bar 5 can be sequentially contacted with each balancing weight 13, so that the training intensity borne by the trainer is gradually increased or decreased in the processes of upward pushing and downward retracting, and the strength of the trainer determines the height capable of pushing the barbell bar 5, so that the complexity of increasing and decreasing the barbell balancing weight can be avoided, and meanwhile, the barbell bar 5 and each balancing weight 13 can be limited by the balancing weight box 4, so that the safety accident caused by accidental falling of the balancing weight 3 can be avoided, and the potential safety hazard is eliminated.

Example two

As shown in fig. 6-8, in the second embodiment, an air cylinder 15 is disposed inside the weight box 4 and below each weight block 13, and specifically, in the second embodiment, two air cylinders 15 are symmetrically disposed below each weight block 13.

The flexible end of cylinder 15 upwards sets up, and flexible end and the diapire of balancing weight 13 mutual contact, and the bottom of cylinder 15 is fixed with the inner wall of weight box 4 through mount pad 18.

The air cylinder 15 is arranged, so that the balancing weight 13 can be lifted to the highest point, and training strengths of different degrees can be conveniently provided for trainers with different strength;

for example:

1. a trainer with small strength can lift the two counter weights 13 in the weight box 4 shown in fig. 6 and 7 through the air cylinder 15, and at the moment, the trainer only needs to bear the weight of the barbell rod 5 and one of the left and right counter weights 13;

2. a trainer with large strength can lift one balancing weight 13 in the weight box 4 through the air cylinder 15, and the trainer only needs to bear the weight of the barbell bar 5 and the left and right balancing weights 13; (alternatively, instead of using the air cylinder 15 to lift any of the weights 13, the trainer would bear the weight of the barbell bar 5 and the left and right weights 13).

Therefore, the invention can also provide proper training intensity for the trainees with different strength, thereby avoiding the trainees from generating discomfort.

In addition, a transverse slot 12 matched with a counterweight block 13 is arranged on the top plate of the counterweight box 4. The transverse slotted hole 12 is provided to facilitate the placement and the removal of the balancing weight 13 and the replacement of the balancing weight 13 with larger weight. In addition, as shown in FIGS. 6 and 7, the air cylinder 15 can push up the weight block 13, thereby providing a sufficient space for the barbell bar 5 to rise.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
