[0018] The implementation mode of the utility model will be described below through specific specific examples, and the person skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification. The utility model can also be implemented or applied through another different specific implementation mode, and each detail in the specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the utility model. It should be noted that the following examples and features in the examples can be combined with each other without conflict.

[0019] It should be noted that the diagrams provided in the following examples only illustrate the basic concept of the utility model in a schematic manner, and only the components related to the utility model are shown in the diagrams, not the number, shape and size of the components during actual implementation. The shape, number and proportion of each component during actual implementation can be changed arbitrarily, and the component layout pattern can also be more complex.

[0020] Some exemplary embodiments of the utility model are described for the purpose of illustration, and it should be understood that the utility model can be implemented in other ways not specifically shown in the drawings.

[0021] AsFigures 1-3 As shown in the figure, in a specific embodiment, an adjustable parallel bar is provided, which comprises a support 1 and two horizontal bars 2 located at the top end of the support 1, and the horizontal bars 2 are provided with adjusting devices. In this embodiment, the adjusting devices are located at the end of the horizontal bars 2. In specific applications, the adjusting devices can be installed at other positions of the horizontal bars 2 according to needs, as long as the positions of the adjusting devices on the two horizontal bars 2 are corresponding.

[0022] In this embodiment, in order to improve the stability of the parallel bar, the support 1 comprises two frame bodies, which are respectively installed at the lower end of the corresponding horizontal bar 2, and the two frame bodies 1-1, 1-2 are connected through the horizontal bar 2. This not only makes the overall structure of the parallel bar more stable, but also improves the compactness of the structure and reduces the floor area.

[0023] The frame body is in an inverted Y shape, which ensures the safety of the parallel bar. In addition, the lower end of the two frame bodies is connected through a plurality of connecting rods to form an auxiliary table structure, which is also practical for users with small stature and can further improve the stability of the parallel bar.

[0024] As shown in the figure, Figure 4 The adjusting device comprises a fixed flange plate 3, an adjusting disc 4, a locking shaft 6 and a grabbing arm 5. The fixed flange plate 3 and the adjusting disc 4 are both disc-shaped structures with a certain thickness. In this embodiment, the flange plate and the adjusting disc 4 are circular in shape for the sake of aesthetics and safety. In specific applications, their shapes can be changed according to needs, for example, they can be polygonal structures. The fixed flange plate 3 is fixed on the horizontal bar 2, and the center of the fixed flange plate 3 is located on the central axis of the horizontal bar 2. The disc surface of the fixed flange plate 3 is arranged vertically to the central axis of the horizontal bar 2. The adjusting disc 4 is sleeved on the horizontal bar 2, and the plane of the adjusting disc 4 is parallel to the plane of the fixed flange plate 3. Based on the consideration of space and strength, in this embodiment, one side surface of the adjusting disc 4 abuts and connects with one side surface of the fixed flange plate 3, and the adjusting disc 4 can rotate around the horizontal bar 2 as the pivot.

[0025] The connecting arm 5-1 is fixedly connected to the adjusting disc 4 via a bushing 5-3. The bushing 5-3 is fitted over the outside of the crossbar 2. The gripping arm 5 includes a connecting arm 5-1 and a gripping arm 5-2, which are approximately L-shaped. One end of the connecting arm 5-1 is fixedly connected to the adjusting disc 4. The gripping arm 5-2 is parallel to the crossbar 2. When the adjusting disc 4 rotates at different angles, the gripping arm 5 rotates around the crossbar 2 as its axis. When the adjusting disc 4 is rotated, the gripping arm 5-2 is at a certain distance from the crossbar 2. When the gripping arm 5-2 is located outside the crossbar 2, the width of the parallel bars is widened. Conversely, when the gripping arm 5-2 is located inside the crossbar 2, a narrow-gap parallel bar structure is achieved. When the gripping arm 5-2 is above the crossbar 2, the training height of the parallel bars is increased. Conversely, the training height can be reduced. Furthermore, the width and height adjustments of the parallel bars can be performed simultaneously to meet different training needs.

[0026] like Figure 5 As shown, in order to fix the position of the gripper arm 5, several through holes 4-1 are provided on the adjusting plate 4. The through holes 4-1 are distributed in a uniform annular array. The side of the fixing flange extends outward to form a guide groove 3-1. One end of the locking shaft 6 extends into the guide groove 3-1, passes through the fixing flange, and is locked in the through hole 4-1. When adjusted to the desired position, the locking shaft 6 is inserted into the corresponding through hole 4-1 to lock the adjusting plate 4 and the fixing flange, thus keeping the gripper arm 5 in the current position. The user can train as needed.

[0027] Based on the adjustable parallel bars described in this embodiment, when adjustments are needed for different training needs, the locking pin is pulled out, causing the adjusting plate 4 to disengage from the fixed flange 3. At this time, with the horizontal bar 2 as the axis, the gripping arm 5 is rotated to the desired position. Simultaneously, the gripping arm 5 drives the adjusting plate 4 to rotate via the bushing 5-3, releasing and pushing the locking shaft 6, allowing the locking shaft 6 to insert into the through hole 4-1 of the adjusting plate 4 to lock, thus completing the adjustment of the parallel bars. Through the adjustment of the parallel bars, users can achieve different training effects. For example, wide-grip and narrow-grip exercises can be performed on parallel bars. Wide-grip exercises can train the outer edge of the pectoral muscles, especially the outer and lower edge of the pectoralis major, suitable for those who want to increase the width and thickness of their pectoral muscles. Wide-grip parallel bars dips can better stimulate the outer and lower edge of the pectoralis major, helping to sculpt a broader chest line; narrow-grip parallel bars dips mainly train the triceps and improve scapular stability, suitable for those who want to enhance the strength and stability of their triceps. Narrow-grip dips provide more stimulation to the triceps and improve scapular stability, making them suitable for strength training and core muscle strengthening. By properly selecting and using wide-grip and narrow-grip dips, you can effectively improve the strength and endurance of your chest and triceps, while also enhancing scapular stability.

[0028] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
