Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a damping support arm for physiotherapy equipment.
Background
The existing rotation damping forms on the market mainly include the following four forms, namely, a first disc spring, the disc spring generates elastic deformation through pressure generated by a locking nut, and friction force is formed during rotation; the disc spring has the advantages that the use cost of the disc spring is low, but the disc spring is in contact with a rotating part, so that the part is easy to generate friction scratch and deformation in use, and the friction force is reduced to a certain degree, and even if a new disc spring is replaced, the use performance is greatly reduced due to the scratch and deformation of the rotating part;
the second type of jacking screw provides rotary damping by jacking pressure generated when the jacking screw is fixed with a contact part; the torque in 1-5NM is generally applied to products with smaller rotating torque, if the torque is tightly pushed to be directly contacted with a rotating part, friction scratch and deformation are easily generated, and the torque is not suitable for an environment with frequent rotating use;
the third plastic damping shaft generates friction force on the side wall through the helical teeth to form rotary damping, the damping generated by the plastic damping shaft is small, the plastic damping shaft is generally used for household products, and the service life of the plastic damping shaft is limited by materials;
the principle of the fourth damping rotating shaft is similar to that of a disc spring, the difference is that damping friction force is not generated by direct contact of the disc spring and a rotating part and is provided by the rotating shaft, the generated rotating damping can be adjusted according to actual conditions, accurate control can be achieved, and different torque requirements can be provided according to different selected damping conditions. When the damping is attenuated to a certain degree, only a new damping rotating shaft needs to be replaced, the damping is gradually generated along with the use times, sudden great attenuation cannot occur, potential safety hazards are generated, and the cost is higher.
Therefore, the existing damping rotating shaft has no angle limit, and some parts can not rotate by 360 degrees, and partial cables can be exposed between the joint connections of the support arm, and the fixing screws of the support arm are exposed. The damping support arm for the physiotherapy equipment provided by the invention can enhance the stability and flexibility of the product.
