Embodiment Construction

[0027] Please refer to Figure 1-10 As shown, the present invention provides a quick-change flexible shaft coupling, which includes a connecting body 1 that clamps or loosens the flexible shaft to be connected. The connecting body 1 is provided with a second mounting hole 5, and the upper part of the second mounting hole 5 is A mounting thread 11 is provided, and a positioning square hole 4 is opened at the bottom of the second mounting hole 5 , and the positioning square hole 4 extends to the other end and communicates with the first mounting hole 3 opened at the other end of the connecting body 1 .

[0028] The connecting body 1 is provided with a circlip 6 that clamps the flexible shaft to be connected. In the connected state, the inner diameter of the circlip 6 is smaller than the outer diameter of the flexible shaft, thereby clamping the flexible shaft and positioning it forward and backward; under the action of the pressing mechanism, the circlip 6 The inner diameter is ...

Abstract

The invention discloses a coupling capable of quickly changing a flexible shaft and relates to the technical field of medical instruments. The coupling comprises a connector for clamping or loosening a to-be-connected flexible shaft, wherein a clamp spring for clamping the to-be-connected flexible shaft is arranged in the connector, and the inner diameter of the clamp spring is smaller than the outer diameter of the flexible shaft in a connection state, so that the flexible shaft is clamped and positioned from front to back; and under the action of a pressing mechanism, the inner diameter of the clamp spring is enlarged, so that the clamped flexible shaft is loosened or the to-be-connected flexible shaft is conveniently inserted, and the flexible shaft and the coupling are installed and removed. A rigid coupling which is adopted for installing the flexible shaft in the past is complex in structure and tedious in installation and removal is omitted, the installation and removal processes are very simple, convenient and rapid, and the installation and replacement efficiency and operability of the flexible shaft are greatly improved. Compared with a common coupling, the coupling disclosed by the invention has the advantages that the concentricity is relatively high, vibration generated when the flexible shaft transmits rotation and torque is reduced, the transmission accuracy of related machines is improved, the service life of the machines is prolonged, meanwhile, the use comfort of operators and related users can be improved, and the comprehensive performance of related products can be improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a quick-change flexible shaft coupling. Background technique [0002] Transmission shafts are divided into soft shafts and hard shafts, both of which have their own advantages and disadvantages. The soft shaft can be bent around obstacles arbitrarily, and can realize rotary motion at a specific position. It can be used for the transmission of various hand-held power machines. In some medical machines In equipment, flexible shafts are used to transmit torque and rotation, such as phlegm discharge machines. One end of the flexible shaft needs to be connected to the output end of the motor through a coupling. The replacement operation meets the needs of the mechanical equipment. At the same time, when the flexible shaft reaches a certain service life, it also needs to be replaced. Therefore, a coupling suitable for the flexible shaft is required. [0003] Existing flexible ...
