Description

A carbon fiber foot with stabilizing parts

technical field

The utility model relates to a carbon fiber foot, in particular to a carbon fiber foot with stable parts.

Background technique

Existing carbon fiber foot (a kind of prosthetic foot) is mainly made up of upper foot plate, lower foot plate and connector etc. Among them, the connection between the upper foot plate and the lower foot plate is mainly connected by several ways such as fastening belt winding, bolt connection or auxiliary clamp. During the use of this kind of carbon fiber foot, both the upper and lower feet will be subjected to variable force frequently. Therefore, if the connection structure between the upper and lower feet is not stable, it will cause the upper and lower feet to be damaged during long-term use. The foot plate is separated or relatively displaced, and the overall prosthetic foot cannot be used normally, which brings certain dangers to the user.

Contents of the invention

In view of the above problems, the purpose of this utility model is to provide a carbon fiber foot with stable components that is stable in connection and safe in use.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a carbon fiber foot with a stable component, which is characterized in that it includes an upper foot plate and two lower foot plates symmetrically arranged below the upper foot plate; wherein, the two The front end of the lower foot plate is fixedly connected with the upper foot plate by a screw respectively; a limit block is also included, and the limit block is a block structure with a cross-section in the shape of "I"; the opposite inner sides of the two lower foot plates respectively inserted in the rectangular slots on both sides of the limit block.

A threaded insert is embedded and fixed on each of the lower feet, and a threaded through hole is opened in the center of the threaded insert; after the screw passes through the upper foot, it is screwed into the threaded through hole of the threaded insert. in the hole.

Affinity glue is coated on the junction of the upper foot plate and the lower foot plate located around the screw.

Affinity glue is coated between the two lower foot plates and the limiting block.

A narrow slit not connected with the end is opened in the middle of the upper foot plate.

A washer is arranged between the nail head of the screw and the upper foot plate.

Because the utility model adopts the above technical scheme, it has the following advantages: 1. The utility model is provided with a limit block between the two lower foot plates, so the relative position between the two lower foot plates is effectively limited, and relative displacement is prevented. generation. 2. In the utility model, a threaded insert is embedded and fixed in each lower foot plate, and the screw penetrates the upper foot plate and then is screwed into the threaded insert, so the stability of the connection between the upper foot plate and the lower foot plate is effectively improved, and the USE RISK. 3. Because the utility model is coated with affinity glue at the fitting place of the upper foot plate and the lower foot plate and the joint of the lower foot plate and the limit block, the rotation between the upper foot plate and the lower foot plate is effectively prevented, and the upper foot plate is improved. The stability of the connection with the base plate.
