[0020] Embodiments of the present application provide an ergonomic socket device, effectively solving the technical problems of existing sockets. By pumping out the air between the skin and the socket and using vacuum for connection, in order to ensure the airtightness of the socket, the skin cannot breathe, and the socket is relatively heavy and cannot be worn for a long time. The binding strap is put on above the stump, and the binding strap is fixed to the stump by adhesion between multiple magic tapes. Then, the carbon fiber outer shell is put on the outside, and the lacing cord is tied to a suitable ventilation hole. During this process, the end of the stump is placed inside the nylon sleeve, which can increase the stability of the carbon fiber outer shell during use. The multiple ventilation holes opened on the carbon fiber outer shell can allow air to enter the inside of the carbon fiber outer shell, ensuring the breathability of the skin. Moreover, the ventilation holes can greatly reduce the weight of the carbon fiber outer shell. Coupled with the stress points formed by the nylon sleeve and the stump, the effect of being able to be worn for a long time is achieved. During installation, the knob can be rotated. The knob will drive the second gear to rotate. Since the second gear meshes with the first gear, the second gear will drive the threaded rod to rotate through the first gear.

By adjusting the position of the top of the lifting support, the device can be adapted to stumps of various lengths. The ball joint can make the threaded sleeve rotate and bend, etc. When the carbon fiber outer shell is lifted, the threaded sleeve will reset under the elastic force of the rubber sleeve, achieving the effect of increasing the flexibility of the prosthetic foot plate.

[0021] Embodiment

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the technical solution in the embodiments of the present application effectively solves the technical problems of existing sockets. By pumping out the air between the skin and the socket and using vacuum for connection, in order to ensure the airtightness of the socket, the skin cannot breathe, and the socket is relatively heavy and cannot be worn for a long time. The general idea is as follows:

[0023] In view of the problems existing in the prior art, the present utility model provides an ergonomic socket device, including a carbon fiber outer shell 1 and a binding strap 2. Multiple ventilation holes 4 are opened on the carbon fiber outer shell 1. Multiple magic tapes 3 are fixedly installed on the binding strap 2. Multiple lacing cords 5 are fixedly installed on the binding strap 2. The bottom end of the carbon fiber outer shell 1 is slidably installed with a base 6, and a lifting support 7 is slidably installed inside the base 6.

[0024] A threaded rod 8 is rotatably installed inside the base 6; the lifting support 7 is threadedly connected to the threaded rod 8. A knob 16 is rotatably installed inside the base 6. A second gear 15 is fixedly installed at the top end of the knob 16. A first gear 14 is fixedly installed at the bottom end of the threaded rod 8.

[0025] The first gear 14 meshes with the second gear 15. A nylon sleeve 9 is fixedly installed at the top end of the lifting support 7. A ball joint 11 is fixedly installed at the bottom end of the base 6. A threaded sleeve 13 is fixedly installed at the bottom end of the ball joint 11. A rubber sleeve 12 is fixedly installed at the bottom end of the base 6.

[0026] Working principle:

[0027] First step, put the bundling strap 2 over the upper part of the stump. Fix the bundling strap 2 to the stump by adhesion between multiple magic tapes 3. Then put the carbon fiber shell 1 on the outside and tie the lacing cord 5 to the appropriate ventilation holes 4. During this process, place the end of the stump inside the nylon sleeve 9, which can increase the stability of the carbon fiber shell 1 during use. The multiple ventilation holes 4 opened on the carbon fiber shell 1 can allow air to enter the inside of the carbon fiber shell 1, ensuring the breathability of the skin. And the ventilation holes 4 can greatly reduce the weight of the carbon fiber shell 1. Together with the stress points formed by the nylon sleeve 9 and the stump, the effect of being able to be worn for a long time can be achieved.

[0028] Second step, during installation, the knob 16 can be rotated. The knob 16 will drive the second gear 15 to rotate. Since the second gear 15 meshes with the first gear 14, the second gear 15 will drive the threaded rod 8 to rotate through the first gear 14. And because the threaded rod 8 is threadedly connected to the lifting support 7, the rotation of the threaded rod 8 can push the lifting support 7 to slide up and down. By adjusting the position of the top end of the lifting support 7, the device can be applicable to stumps of various lengths. The ball joint 11 can make the threaded sleeve 13 perform actions such as rotation and bending. When the carbon fiber shell 1 is lifted, the threaded sleeve 13 will reset under the elastic force of the rubber sleeve 12, achieving the effect of increasing the flexibility of the prosthetic foot plate.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
