This application discloses a safety buckle structure for the waist module and the waist module itself in a lower limb training device.

[0028] The core of this utility model is to provide a safety buckle structure and a waist module for a lower limb training device.

[0029] Please refer to Figures 1 to 3 .

[0030] The safety buckle structure for the waist module in the lower limb training device provided by this utility model and the waist module include a socket 2 fixedly connected to the support rod 1 in the waist module and an insertion port 3 fixed to one side of the weight reduction strap. The insertion port 3 cooperates with the socket 2 and is inserted into the socket 2. A limit structure is provided between the insertion port 3 and the socket 2 so that the insertion port 3 is fixed in the socket 2.

[0031] The open end of the socket 2 is provided with a tapered guide to guide the socket 3 to be accurately inserted into the socket 2.

[0032] Specifically, the plug 3 mates with the socket 2 and is inserted into the socket 2. A limiting structure between the plug 3 and the socket 2 secures the plug 3 within the socket 2, achieving a stable connection between the weight-reducing strap and the lumbar module. This limiting structure effectively prevents the plug 3 from detaching from the socket 2, ensuring the stability of the connection during rehabilitation training. The open end of the socket 2 has a tapered guide. When the plug 3 needs to be inserted into the socket 2, the tapered guide, with its gradually narrowing shape, provides a clear direction for insertion, ensuring accurate insertion into the socket 2. This avoids installation inconvenience and malfunctions caused by misaligned insertion of the plug 3, improving the accuracy and convenience of the safety buckle connection.

[0033] In the aforementioned lower limb training equipment, the waist module uses a safety buckle structure. The socket 2 and the insertion port 3 enable quick installation and removal of the weight-reducing strap and the waist module, and the limiting structure ensures the stability of the connection.

[0034] The safety buckle structure for the waist module and the waist module in the lower limb training device provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0035] In one specific implementation, reference is made to... Figure 2 and Figure 3 The limiting structure includes a rotating plunger 4 fixedly connected to the socket 2, a limiting hole is opened in the socket 3, and a pin inside the rotating plunger 4 is inserted into the limiting hole.

[0036] Specifically, the limiting structure includes a rotating plunger 4 fixedly connected to the socket 2. A limiting hole is formed inside the socket 3. By rotating the rotating plunger 4, a pin inside the rotating plunger 4 is inserted into the limiting hole of the socket 3. In practical applications, when the socket 3 is inserted into the socket 2, the pin of the rotating plunger 4 inserts into the limiting hole, effectively preventing the socket 3 from detaching from the socket 2. This ensures the socket 3 is securely fixed inside the socket 2, thereby guaranteeing the stability of the safety buckle connection and improving the reliability of the safety buckle structure used to connect the weight-reducing strap and the lumbar module. This ensures that the connection between the lumbar module and the weight-reducing strap will not easily loosen or separate during rehabilitation training, enhancing the safety of rehabilitation training. The length and diameter of the pin need to match the limiting hole to ensure effective insertion and fixation, thus firmly securing the socket 3 inside the socket 2 and preventing it from coming out.

[0037] Based on any of the above embodiments, refer to Figure 2 and Figure 3 The pin end of the rotating plunger 4 is provided with a tapered structure to assist the pin in inserting into the limiting hole of the socket 3.

[0038] Specifically, the rotating plunger 4 is fixedly connected to the socket 2. The pin end of the rotating plunger 4 has a tapered structure. When the socket 3 is inserted into the socket 2, the pin faces the limiting hole in the socket 3. The guiding effect of the tapered structure at the end of the pin effectively assists the pin in inserting into the limiting hole of the socket 3, ensuring that the socket 3 is reliably fixed in the socket 2. This allows the safety buckle structure to better perform its limiting and fixing functions, improving the stability of the lumbar module in the entire lower limb rehabilitation training equipment. The tapered structure makes it easier for the pin to be aligned when inserted into the limiting hole, reducing insertion resistance. For example, as the socket 3 is gradually inserted into the socket 2, the tapered end of the pin can guide the pin smoothly into the limiting hole. Even if there are some small deviations, they can be automatically corrected by the tapered structure, improving the accuracy and efficiency of insertion.

[0039] Based on any of the above embodiments, refer to Figure 4 A push-button switch is provided at the end of the limiting hole. An auxiliary hole is provided on the socket 2 perpendicular to the limiting hole. An electromagnet 9 is provided at the end of the auxiliary hole. The electromagnet 9 is electrically connected to the push-button switch. A positioning hole is provided on the socket 3 to cooperate with the auxiliary hole. A positioning rod 11 is slidably provided in the positioning hole. A positioning magnet 10 is provided at the end of the positioning rod 11 near the electromagnet 9. A return spring 12 is provided between the positioning rod 11 and the positioning hole so that the positioning rod 11 returns to the positioning hole after the positioning magnet 10 separates from the electromagnet 9.

[0040] Specifically, a push-button switch is provided at the end of the limiting hole. An auxiliary hole is provided perpendicular to the limiting hole on the socket 2, and an electromagnet 9 electrically connected to the push-button switch is located at the end of the auxiliary hole. A positioning hole is provided on the insertion port 3 to mate with the auxiliary hole. A positioning rod 11 is slidably installed in the positioning hole, and a positioning magnet 10 is located at the end of the positioning rod 11 near the electromagnet 9. A return spring 12 is provided between the positioning rod 11 and the positioning hole. When the insertion port 3 is inserted into the socket 2, the pin of the rotating plunger 4 inserts into the limiting hole, triggering the push-button switch. This energizes the electromagnet 9, generating magnetic force that attracts the positioning magnet 10 on the positioning rod 11, causing the positioning rod 11 to extend from the positioning hole and insert into the auxiliary hole, further securing the insertion port 3 and the socket 2. When separation is required, the pin leaves the limiting hole, the push-button switch is turned off, the electromagnet 9 loses its magnetic force, and the return spring 12 returns the positioning rod 11 to its original position within the positioning hole. This not only enhances the stability of the safety buckle structure connection but also makes the installation and disassembly of the insertion port 3 and the socket 2 more convenient, improving the efficiency and reliability of the lower limb training equipment during use.

[0041] It should be noted that after being energized, the attraction of the electromagnet 9 to the positioning magnet 10 is greater than the reset force of the return spring 12. At the same time, without the intervention of external force, the return spring 12 and the positioning rod 11 are both inside the positioning hole.

[0042] Based on any of the above embodiments, refer to Figure 2and Figure 3 The socket 2 is equipped with a ball joint assembly on the side near the support rod 1 to allow the patient more freedom of movement in flexion and extension.

[0043] Specifically, a ball joint assembly is provided on the side of the socket 2 near the support rod 1. When the ball joint assembly is in operation, its structure allows the socket 2 to rotate in the pitch direction relative to the support rod 1, thereby increasing the patient's freedom of pitch movement and making the patient more flexible during rehabilitation training.

[0044] Based on any of the above embodiments, refer to Figure 2 and Figure 3 The ball joint assembly includes a ball hinge cover 5 and a ball bearing 6. The ball hinge cover 5 is fixedly connected to the support rod 1. The ball bearing 6 is disposed between the ball hinge cover 5 and the socket 2 to allow the socket 2 to rotate in the pitch direction relative to the support rod 1.

[0045] Specifically, the ball hinge cover 5 is fixedly connected to the support rod 1, and the articulated ball bearing 6 is located between the ball hinge cover 5 and the socket 2. This assembly allows the socket 2 to rotate in the pitch direction relative to the support rod 1, increasing the patient's freedom of movement and ensuring both a certain degree of freedom of motion and stable support for the body. The ball hinge cover 5 is generally made of high-strength metal and is fixed to the support rod 1 by bolts or welding, ensuring the strength and stability of the connection. The articulated ball bearing 6 consists of a ball and a bearing seat. The ball can rotate freely within the bearing seat, thus enabling the socket 2 to rotate flexibly in the pitch direction relative to the support rod 1.

[0046] Based on any of the above embodiments, refer to Figure 2 and Figure 3 The ball joint assembly also includes a screw rod 7, which passes through the ball bearing 6 and is fixed to the socket 2.

[0047] Specifically, the screw rod 7 passes through the joint ball bearing 6 and is fixed to the socket 2, forming a stable connection structure between the joint ball bearing 6 and the socket 2. In this way, the joint ball bearing 6 can rotate around the screw rod 7, ensuring that the socket 2 can rotate smoothly in the pitch direction relative to the support rod 1, thereby increasing the patient's freedom of pitch movement and improving the patient's flexibility and comfort during rehabilitation training.

[0048] Furthermore, a washer 8 is provided between the ball bearing 6 and the inner side of the socket 2, and the screw rod 7 passes through the washer 8.

[0049] Specifically, the gasket 8 is located between the inner side of the ball bearing 6 and the socket 2, and the screw rod 7 passes through the gasket 8. This makes the installation of the ball bearing 6 and the socket 2 more secure, avoids unnecessary wear caused by direct contact between the two, extends the service life of the safety buckle structure, improves the stability and reliability of the entire device, and helps maintain the support and restraint effect for the patient during rehabilitation training. The gasket 8 protects the ball bearing 6 and disperses pressure, preventing damage to the ball bearing 6 due to friction or excessive pressure during use. The gasket 8 can be made of elastic materials such as rubber or plastic, which can buffer pressure and extend the service life of the ball bearing 6.

[0050] Based on any of the above embodiments, the gasket 8 has an annular structure and is sleeved around the screw rod 7.

[0051] Specifically, the annular structure design allows the gasket 8 to be evenly distributed between the ball bearing 6 and the inner side of the socket 2, better fulfilling its protective and cushioning functions. Simultaneously, the way it is fitted around the screw rod 7 ensures that the gasket 8 will not shift during use and will always remain in the correct position.

[0052] This application discloses a safety buckle structure for the lumbar module in a lower limb training device, and the implementation principle of the lumbar module is as follows: It enables rapid installation and disassembly of the weight-reducing strap and the lumbar module. A limiting structure ensures the stability of the connection, and the engagement of the pin of the rotating plunger 4 with the limiting hole of the insertion port 3 prevents the insertion port 3 from dislodging. The tapered guide and the tapered structure at the end of the pin improve the convenience and accuracy of insertion. The cooperation between the positioning magnet 10 and the electromagnet 9 further enhances the stability between the insertion port 3 and the socket 2. The ball joint assembly allows for greater freedom of movement for the patient, increasing the comfort and flexibility of rehabilitation training. Compared to traditional connection methods, this structure significantly improves the efficiency of component replacement and adjustment during rehabilitation training, providing better protection for lower limb rehabilitation training and overcoming the problems of complex connection methods and low disassembly efficiency in existing technologies.
