Technical Field

[0001] This utility model belongs to the field of movable joints for traditional Chinese medicine fumigation instruments, specifically a movable joint with locking mechanism. Background Technology

[0002] A movable joint is a device specifically designed to connect the various links of a robotic arm and enable relative movement. This device has the function of flexible rotation at multiple angles, which makes the robotic arm more flexible and free when performing various complex tasks. Movable joints have a wide range of applications, especially in the fields of robotics and medical devices, where they play a vital role. In the use of traditional Chinese medicine fumigation devices, the coordinated operation of the movable joints and the support arms enables fumigation treatment in different directions, thereby meeting the personalized needs of different patients and improving the treatment effect. The precise design and high efficiency of the movable joints ensure the stability and reliability of the fumigation device during operation, providing patients with safer and more convenient medical services.

[0003] However, in current applications of traditional Chinese medicine fumigation devices, existing movable joints mostly use damped rotating shafts to achieve rotational adjustment. This method has some obvious limitations, especially when it is necessary to maintain a stable angle. It lacks an effective locking mechanism, which leads to the joints being prone to unexpected movement during treatment due to the lack of locking, affecting the stability of use.

[0004] In summary, this utility model provides a movable joint with locking mechanism to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0014] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0015] Example 1 like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a locking movable joint, including a support arm assembly 100 for supporting the nozzle of a traditional Chinese medicine fumigation device, and a movable joint assembly 200, including a fixed base 210, a rotating ball head 220 rotatably connected to the inner cavity of the fixed base 210, a first toothed ring 230 located on one side of the inner cavity of the fixed base 210, a second toothed ring 240 located on one side of the rotating ball head 220, a spring 250 located between the first toothed ring 230 and the second toothed ring 240, a fixing bolt 260 located at one end of the fixed base 210, and a nut 270 located at the other end of the fixed base 210.

[0016] like Figure 1-4 As shown, the first toothed ring 230 is fixed to the fixed base 210, and the second toothed ring 240 is fixed to the rotating ball head 220. The two toothed rings mesh with each other and form a physical engagement when there is no external force intervention, preventing the rotating ball head 220 from rotating freely. The spring 250 is placed between the two toothed rings and applies axial pressure to keep the tooth surfaces tightly fitted. The fixing bolt 260 passes through the entire joint assembly and is screwed into the nut 270. When the fixing bolt 260 is tightened, the first toothed ring 230 is pushed to compress the spring 250, further compressing the second toothed ring 240, thereby increasing the positive pressure on the tooth surface and increasing the locking torque. Conversely, the pressure can be reduced by appropriately loosening the fixing bolt 260. The angle of the rotating ball head 220 can be manually adjusted, and the locking and unlocking of the movable joint can be achieved by rotating the fixing bolt 260. When the position of the fumigation nozzle needs to be adjusted, simply rotate the fixing bolt 260 in the opposite direction to reduce the pressure of the spring 250. The teeth of the first toothed ring 230 and the second toothed ring 240 will separate. At this time, the ball head 220 can rotate freely, driving the support arm assembly 100 to adjust to the target angle. After the adjustment is in place, tighten the fixing bolt 260 again. The spring 250 will return to the compressed state, and the two toothed rings will re-engage to form a lock, ensuring the stability of the nozzle position. The mechanical structure achieves stepless angle adjustment and reliable locking, avoiding the problem of easy loosening of traditional damping shafts, and significantly improving the stability of the Chinese medicine fumigation device.

[0017] Example 2 Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0018] In this embodiment, the support arm assembly 100 includes a connecting rod 110, a first support rod 120 located at the lower end of the connecting rod 110, and a second support rod 130 located at the upper end of the connecting rod 110.

[0019] The movable joint assembly 200 is provided with at least four sets. The connecting rod 110 is connected to the first support rod 120 through a movable joint assembly 200. The first support rod 120 is connected to the main unit of the Chinese herbal fumigation instrument through a movable joint assembly 200. The connecting rod 110 is connected to the second support rod 130 through a movable joint assembly 200. The other end of the second support rod 130 is fixed to the fumigation instrument nozzle through a movable joint assembly 200.

[0020] The rotating ball head 220 is rotatably connected to the inner cavity of the fixed seat 210 via a rotating shaft, the second toothed ring 240 is fixedly connected to the rotating ball head 220, and the first toothed ring 230 is fixedly connected to the fixed seat 210.

[0021] The first toothed ring 230 meshes with the second toothed ring 240, and the two ends of the spring 250 contact the second toothed ring 240 and the first toothed ring 230 respectively.

[0022] Nut 270 is fixedly connected to fixed base 210. One end of fixing bolt 260 passes through fixed base 210, first toothed ring 230, second toothed ring 240 and spring 250 and extends to the inner cavity of nut 270, and is threadedly connected to the inner cavity of nut 270.

[0023] like Figure 1-4As shown, when it is necessary to adjust the angle of the support arm assembly 100, by rotating the fixing bolt 260, since one end of the fixing bolt 260 passes through the fixing seat 210, the first toothed ring 230, the second toothed ring 240 and the spring 250 and extends into the inner cavity of the nut 270 and is threadedly connected to the inner cavity of the nut 270, rotating the fixing bolt 260 will cause relative movement between the first toothed ring 230 and the second toothed ring 240, so that they engage or disengage; The first toothed ring 230 is fixedly connected to the fixed base 210, and the second toothed ring 240 is fixedly connected to the rotating ball head 220. Under the adjustment of the fixing bolt 260, the spring 250 is compressed or released, thereby changing the meshing state between the first toothed ring 230 and the second toothed ring 240, so that the rotating ball head 220 can rotate around the axis in the inner cavity of the fixed base 210, thereby driving the support arm assembly 100 connected to the rotating ball head 220 to rotate, realizing the angle adjustment. It can flexibly rotate and adjust the angle, and can reliably lock after adjusting to the required angle.

[0024] In use, the first support rod 120 is first connected to the main unit of the Chinese herbal fumigation device through a movable joint assembly 200. Two movable joint assemblies 200 are fixed at both ends of the connecting rod 110. The lower movable joint assembly 200 is connected to the first support rod 120, and the upper movable joint assembly 200 is connected to the second support rod 130. The second support rod 130 is connected to the fumigation device nozzle through the movable joint assembly 200. Through the coordinated cooperation of the four sets of movable joint assemblies 200, the connecting rod 110, the first support rod 120, and the second support rod 130, not only can the nozzle of the fumigation device be supported, but the fumigation direction can also be easily adjusted. When the angle needs to be adjusted, loosen the fixing bolt 260 to gradually separate the first toothed ring 230 and the second toothed ring 240. Then, rotate the rotating ball head 220 to adjust the angle. After the adjustment is completed, rotate the fixing bolt 260 to gradually mesh the first toothed ring 230 and the second toothed ring 240 to complete the locking.
