Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training equipment, and in particular to a vitality gymnastics stick. Background Technology

[0002] Gymnastics sticks, as a common exercise tool, are frequently used in physical training to enhance upper limb strength and improve body coordination and flexibility. Similarly, they demonstrate significant application value in the field of rehabilitation training. By guiding patients to perform specific gymnastics stick exercises, it is possible to effectively help restore upper limb joint range of motion and muscle strength, while simultaneously enhancing balance and coordination, thus playing a positive supporting role in the rehabilitation process.

[0003] However, existing gymnastic bars used in rehabilitation training suffer from a fixed center of gravity and uneven mass distribution, leading to unnecessary shaking or deviations in movement trajectories during use, severely impacting the smoothness and precision of movements. Furthermore, existing gymnastic bars lack consideration for individual differences among rehabilitation patients; this "one-size-fits-all" design limits the optimal upper limb functional rehabilitation outcomes for patients. Therefore, a dynamic gymnastic bar has been invented to address the shortcomings of existing gymnastic bars in terms of flexibility and center of gravity design. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dynamic gymnastics stick.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dynamic gymnastic stick includes a hollow shell and a grip portion located at the bottom of the hollow shell. The hollow shell is composed of an upper shell and a lower shell. The upper shell is connected to the lower shell via a first buckle. The grip portion is fixedly connected to the bottom of the lower shell. The upper shell includes a top cover. An annular slide rail is provided on the inner wall of the top cover. A counterweight is slidably connected to the annular slide rail. The counterweight includes a counterweight shell and a counterweight core. A door panel is hinged to one side of the counterweight shell. The door panel and the counterweight shell form a displacement cavity. Springs are symmetrically arranged in the displacement cavity. One end of each spring is connected to an arc-shaped fixing block. The counterweight core is located inside the arc-shaped fixing block. A connecting block is fixedly connected to the other side of the counterweight shell. The connecting block drives the counterweight to move circumferentially along the annular slide rail.

[0007] Preferably, the outer wall of the top cover is provided with a semi-circular guide groove corresponding to the position of the annular slide rail, and the connecting block includes a through section and an operating head. The operating head is located above the guide groove, and the through section passes through the top cover upward and is connected to the operating head.

[0008] Preferably, a sealing strip is embedded in the middle position of the guide groove.

[0009] Preferably, the door panel is provided with a second buckle, the second buckle including an upper fastening part provided on one side of the door panel, a lower fastening part provided on the corresponding side of the counterweight housing, and an operating handle movably connected to the upper fastening part, the upper fastening part being fastened to the lower fastening part through the operating handle.

[0010] Preferably, the fastening surfaces of the upper and lower housings are provided with a slot, and the slot is stepped.

[0011] Preferably, the surface of the grip portion is arrayed with a plurality of hemispherical anti-slip protrusions.

[0012] The beneficial effects of this utility model are:

[0013] By setting an annular slide rail on the inner wall of the hollow shell top cover, the counterweight block and the annular slide rail form a circumferential fit, and the connecting block on the counterweight block penetrates through the top cover, extends to the guide groove on the outer wall of the top cover, and connects to the operating head in the guide groove. Moving the operating head can drive the counterweight block to move along the annular slide rail, thereby flexibly adjusting its circumferential position and realizing the dynamic adjustment of the center of gravity distribution of the gymnastic bar. By hinged to a door panel on one side of the counterweight block, a replacement cavity is formed. A second buckle is set on the door panel, and the door panel is fastened or separated from the counterweight shell by means of the operating handle, and the replacement cavity is quickly opened and closed. In conjunction with the symmetrically arranged springs and arc-shaped fixing blocks in the replacement cavity, the counterweight core is released or different specifications of counterweight cores are inserted under the elastic force of the spring, which facilitates the replacement of the counterweight core. This allows the gymnastic bar to be adapted to different rehabilitation patients and meet the progressive training from light load (early rehabilitation) to high load (late rehabilitation), thereby fully meeting the adaptive needs of different rehabilitation patients and different rehabilitation stages for the weight of the gymnastic bar.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figures 1-10 As shown, a dynamic gymnastic bar includes a hollow shell 1 and a grip part 2 located at the bottom of the hollow shell 1. The hollow shell 1 is composed of an upper shell 11 and a lower shell 12. The grip part 2 is fixedly connected to the bottom of the lower shell 12. When the user holds the gymnastic bar to perform various movements, the hand muscles are effectively exercised.

[0028] Furthermore, the surface of the grip portion 2 is arrayed with a plurality of hemispherical anti-slip protrusions 10. The anti-slip protrusions 10 significantly increase the friction between the grip portion 2 and the user's hand. During rehabilitation training, the user's hand is in close contact with the grip portion 2, and the anti-slip protrusions 10 effectively prevent the hand from slipping, reducing accidental injuries caused by hand slippage, thereby improving the safety and reliability of use.

[0029] Furthermore, the upper shell 11 is connected to the lower shell 12 via the first buckle 13, allowing the upper shell 11 and the lower shell 12 to be quickly disassembled for subsequent replacement of the counterweight 4. In addition, the mating surfaces of the upper shell 11 and the lower shell 12 are provided with stepped grooves 14, which allow the upper shell 11 and the lower shell 12 to be tightly engaged, forming a reliable sealing barrier to ensure that the upper shell 11 and the lower shell 12 will not easily separate during use.

[0030] refer to Figure 1 , Figure 3 As shown, the upper housing 11 includes a top cover 111. The inner wall of the top cover 111 is provided with an annular slide rail 3. A counterweight 4 is slidably connected to the annular slide rail 3. The design of the annular slide rail 3 allows the counterweight 4 to slide and adjust on the annular path on the inner wall of the top cover 111, thereby realizing the circumferential position adjustment of the counterweight 4. This allows the counterweight 4 to be positioned in the most ideal position according to different training movements and needs.

[0031] Furthermore, the counterweight 4 includes a counterweight shell 41 and a counterweight core 42. A connecting block 7 is fixedly connected to one side of the counterweight shell 41. The outer wall of the top cover 1 is provided with a semi-arc guide groove 8 corresponding to the position of the annular slide rail 3. The connecting block 7 includes a through section 71 and an operating head 72. The through section 71 of the connecting block 7 passes upward through the top cover 111 and is connected to the operating head 72 which is slidably disposed in the guide groove 8. The user can move the counterweight 4 along the annular slide rail 3 by sliding the operating head 72 in the guide groove 8. The operating head 72 is detachable so that it can be used in two semi-arc guide grooves 8, thereby flexibly adjusting the position of the counterweight 4 on the annular slide rail 3 according to actual usage requirements.

[0032] Specifically, different rehabilitation stages and training goals require different weight distributions on the gymnastic bar. Users can freely adjust the position of counterweight 4 according to their physical condition, rehabilitation progress, and training plan, thereby changing the center of gravity and swing characteristics of the gymnastic bar.

[0033] Furthermore, a sealing strip 9 is embedded in the middle of the guide groove 8. The sealing strip 9 generates a certain friction with the operating head 72, which can fix the operating head 72 and keep it stable after it is adjusted to a suitable position, preventing it from easily shifting. Moreover, the guide groove 8, as the channel for the sliding of the operating head 72, is a part that connects the inside of the upper housing 11 with the external environment, which can easily lead to the entry of dust and debris. The sealing strip 9, which fills the middle of the guide groove 8, effectively prevents dust and debris from entering the guide groove 8 and the internal structure, thereby ensuring smooth sliding and stable connection.

[0034] refer to Figure 8 , Figure 9 As shown, a door panel 5 is hinged to one side of the counterweight housing 41. A second buckle 51 is provided on the door panel 5. The second buckle 51 can provide a fastening force to ensure that the door panel 5 will not loosen or open due to the use of the gymnastic bar during use, thereby ensuring the overall structural stability of the counterweight block 4.

[0035] Furthermore, the second buckle 51 includes an upper latching part 511 disposed on one side of the door panel 5, a lower latching part 512 disposed on the corresponding side of the counterweight housing 41, and an operating handle 513. The operating handle 513 is movably connected to the upper latching part 511. The upper latching part 511 and the lower latching part 512 can be separated or latched by the operating handle 513, so as to realize the quick opening and closing of the door panel 5, thereby making the replacement process of counterweight cores 42 of different weights simple and quick, thus meeting different training needs.

[0036] refer to Figure 10 As shown, the door panel 5 and the counterweight housing 41 form a displacement cavity 6. The counterweight core 42 is located inside the displacement cavity 6. Springs 411 are symmetrically arranged inside the displacement cavity 6. One end of the spring 411 is fixedly connected to the inner wall of the counterweight housing 41, and the other end of the spring 411 is connected to an arc-shaped fixing block 412. The counterweight core 42 is placed inside the two arc-shaped fixing blocks 412. The symmetrically arranged springs 411 will push the arc-shaped fixing blocks 412 to apply pressure to the counterweight core 42 through their own elasticity, thereby stably fixing the counterweight core 42 in the displacement cavity 6 and preventing it from shaking or shifting during use, thereby improving the safety and reliability of the gymnastic bar.

[0037] Furthermore, when it is necessary to replace the counterweight core 42, simply overcome the elastic force of the spring 411 and press the arc-shaped fixing block 412 to both sides to easily remove the counterweight core 42. Therefore, the operation is simple and convenient, without the need for additional tools, and it is convenient for users to adjust the weight of the counterweight core 42 in a timely manner according to their own needs.

[0038] Furthermore, the elastic properties of the spring 411 enable the arc-shaped fixing block 412 to provide adaptive clamping for counterweight cores 42 of different sizes. Even if there are certain errors or differences in the external dimensions of the counterweight core 42, it can be firmly fixed in the replacement cavity 6 through the extension and retraction adjustment of the spring 411, thereby improving the compatibility of the counterweight block 4 with counterweight cores 42 of different types and specifications.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
