[0024] As Figure 1 and Figure 2 As shown in the figure, a balance bar portable adjusting structure comprises a pair of mounting brackets 1, a pair of first rollers 2 and second rollers 3 of different diameters movably connected above the mounting brackets 1, the second rollers 3 being smaller in diameter than the first rollers 2, and a balance bar 4 arranged above the first rollers 2 and the second rollers 3, and a flange counterweight 5 mechanically connected to both ends of the balance bar. The mounting bracket 1 is conical in shape and is provided with rotating clamping grooves 6 corresponding to the first rollers 2 and the second rollers 3, and a roller structure 8 penetrating through the mounting bracket 1 is arranged below the mounting bracket 1, and the two sides of the roller structure 8 are connected to a sliding sleeve 10 through a rotating shaft 9, and the sliding sleeve 10 is connected to the bottom plate of the mounting bracket. The bottom end of the sliding sleeve 10 is provided with a blocking rod 11 penetrating through the sliding sleeve 10 and tightly abutting against the bottom plate of the mounting bracket, and an L-shaped limiting plate 12 is arranged outside the other end of the blocking rod 11 to limit the sliding direction.
[0025] In this embodiment, the mounting bracket 1 serves as the base component of the entire structure, on top of which a pair of first and second rollers 2 and 3 with different diameters are mounted through a movable connection. The diameter of the second roller 3 is smaller than that of the first roller 2, which allows the balance bar 4 to naturally rotate according to the distribution of its own weight when placed on the rollers, until the heavier end is at the lower position, thereby quickly identifying the unbalanced position of the balance bar. The flange counterweight 5 is mechanically connected to both ends of the balance bar 4, and by adjusting the mass or position of the flange counterweight 5, the balance state of the balance bar 4 can be finely adjusted. The rotating clamping groove 6 provided on the mounting bracket 1 corresponds to the first and second rollers 2 and 3, and the bearing structure 7 on the rollers penetrates through itself and the mounting bracket 1, ensuring smooth rotation of the rollers and providing stable support for the adjustment of the balance bar 4. The mounting bracket 1 is conical in shape, with a roller structure 8 at the bottom. The roller structure 8 is connected to the sliding sleeve 10 through a rotating shaft 9, and the bottom end of the sliding sleeve 10 is provided with a blocking rod 11. The L-shaped limiting plate 12 externally fitted to the blocking rod 11 limits the sliding direction of the blocking rod 11. By controlling the position of the blocking rod 11, the roller structure 8 can be in contact with or separated from the ground, thereby facilitating the movement and fixation of the device.
[0026] In this embodiment, the ingenious combination of various components achieves multiple beneficial effects of the portable balance bar adjustment structure. First, through the first and second rollers 2 and 3 with different diameters and the adjustable flange counterweight 5, the unbalanced position of the balance bar 4 can be quickly identified and adjusted, greatly improving the efficiency and accuracy of balance adjustment. Second, the conical design of the mounting bracket 1 and the adjustable roller structure 8 make the entire device not only portable and mobile, but also stable when needed, adapting to different use environments and operation requirements. Finally, the coordinated action of components such as the rotating clamping groove 6, bearing structure 7, rotating shaft 9, sliding sleeve 10, blocking rod 11, and limiting plate 12 ensures the stability and reliability of the device during adjustment and use, effectively improving the practicality and innovation of the portable balance bar adjustment structure.
[0027] As shown in Figure 3 and Figure 4 , when the blocking rod 11 is placed above the rotating shaft 9, the roller structure 8 contacts the ground; when the blocking rod 11 is placed below, the roller structure 8 is separated from the ground, and the mounting bracket 1 contacts the ground. The rotating direction of the roller structure 8 is parallel to the length direction of the balance bar 4, enabling portable adjustment. The diameter difference between the first and second rollers 2 and 3 cooperates with the rotating clamping groove 6 and bearing structure 7, allowing the balance bar 4 to be stably supported and easily adjusted at different positions. The flange counterweight 5 can adjust the center of gravity of both ends of the balance bar.
[0028] In this embodiment, the components and parameters are as follows:
[0029] Mounting bracket 1: overall conical, material can be selected with aluminum alloy, to reduce weight and ensure strength. Its taper angle is usually between 30°-60°, the specific size can be determined according to the length of the balance bar 4 and the use scene, such as for small balance bar, the mounting bracket height can be in 10-20cm, the bottom plate diameter is in 15-25cm.
[0030] The first roller 2 and the second roller 3: both are polyurethane material, with good wear resistance and elasticity. The diameter of the first roller 2 is generally 8-12cm, and the diameter of the second roller 3 is 4-6cm, both of which are installed on the mounting bracket 1 through precision bearing, bearing 7 can be selected with 608ZZ type deep groove ball bearing, its inner diameter is 8mm, outer diameter is 22mm, width is 7mm, to ensure the smooth rotation of the roller.
[0031] Balance bar 4: carbon fiber material is adopted, the length is 1-2m, the diameter is 4-8cm, and threaded holes are provided at both ends to connect with the flange counterweight 5. The flange counterweight 5 is generally made of cast iron material, and the single counterweight can be adjusted between 0.5-3kg, which is connected with the balance bar 4 through bolt, and the gravity center of the balance bar can be finely adjusted.
[0032] Rotary clamping groove 6: corresponding to the roller position on the mounting bracket 1, the groove width is slightly larger than the roller diameter, and the groove depth is about 1 / 3-1 / 2 of the roller diameter, which is used to stabilize and support the roller and limit its radial displacement.
[0033] Roller structure 8: the material is the same as that of the first roller 2 and the second roller 3, the diameter is 6-10cm, which is installed below the mounting bracket 1, connected with the sliding sleeve 10 through the rotating shaft 9, the rotating shaft 9 can be selected with 8.8 carbon steel shaft, the diameter is 6-10mm. The sliding sleeve 10 is made of nylon, the inner diameter matches the rotating shaft 9, and the outer diameter matches the mounting hole on the bottom plate of the mounting bracket 1, which can slide along the rotating shaft 9 and drive the roller structure 8 to rise and fall.
[0034] Blocking rod 11: made of stainless steel, diameter 8-12mm, length 15-25cm, one end is fixedly connected with the bottom end of the sliding sleeve 10, the other end penetrates through the L-shaped limiting plate 12. The limiting plate 12 is made of aluminum alloy, the thickness is 3-5mm, which is fixed on the bottom plate of the mounting bracket 1 through screw, used to limit the sliding direction of the blocking rod 11.
[0035] In actual use, when the device needs to be moved, the blocking rod 11 is placed above the rotating shaft 9, the roller structure 8 contacts the ground, at this time the device can be conveniently moved through the roller structure 8; when the balance bar 4 needs to be adjusted, the blocking rod 11 is placed below the rotating shaft 9, the roller structure 8 is away from the ground, the mounting bracket 1 contacts the ground, and a stable support platform is provided for the balance bar 4. The balance bar 4 is placed on the first roller 2 and the second roller 3, due to the difference in roller diameters, the balance bar 4 will naturally rotate under the condition of imbalance of its own weight, until the heavier end is in a lower position, facilitating quick identification of the unbalanced position. At this time, the center of gravity of the two ends of the balance bar 4 can be finely adjusted by increasing or decreasing the flange counterweight 5 or adjusting its position on the balance bar 4, until the balance bar 4 reaches the ideal balanced state. The whole device has compact structure and simple operation, and the cooperation of various components realizes the portable adjustment function of the balance bar, improves the efficiency and precision of the balance bar adjustment, is convenient to carry and move, and has good practicability and innovation.
