Embodiment Construction

[0012] The present invention will be described in detail below with reference to the accompanying drawings.

[0013] Such as figure 1 As shown, the torque-adjustable tensioning mechanism includes four parts: a tensioning joint 1 , a thin leaf spring 2 , a tensioning knob 3 and a C-shaped buckle 4 . The tensioning joint 1 is the connection between the torque-adjustable tensioning mechanism and the tensioned parts, and its internal shape can be customized according to the shape of the tensioned parts. The thin leaf spring 2 is made of spring steel and provides the elastic moment required for tensioning. The tensioning knob 3 provides a manually operated contact portion for convenient tensioning operation. The C-shaped buckle fixes the above four components to form a whole.

[0014] Such as figure 2 As shown, the tensioning joint 1 has a scale line 5 showing the magnitude of the tensioning moment, each scale line represents 0.05N·m, and the maximum torque range is determined...

Abstract

The invention belongs to the technical field of medical instrument assembly and particularly relates to an adjustable torque tensioning mechanism. The adjustable torque tensioning mechanism comprises a tensioning connector, a tensioning rotary knob, a thinned plate spring and a C-shaped retaining ring. The C-shaped retaining ring is used for fixing the tensioning connector, the thinned plate spring and the tensioning rotary knob. The tensioning rotary knob can drive the thinned plate spring and the tensioning connector to rotate along a shaft. The thinned plate spring is arranged in a cavity of the tensioning rotary knob. Scale marks are arranged on the tensioning connector. Scale pointers are arranged on the tensioning rotary knob. The adjustable torque tensioning mechanism is simple in structure, small in size, capable of precisely outputting low level torque due to the fact that elastic torque is provided by the thinned plate spring and the scale marks of the tensioning connector are pointed through the scale pointers of the tensioning rotary knob, and suitable for assembly of small-sized medical instruments.

Description

technical field [0001] The invention belongs to the technical field of medical appliance assembly, and in particular relates to a tensioning mechanism with adjustable torque. Background technique [0002] In the technical field of medical device assembly, the belt-type connection mechanism needs to be tensioned. Because the physical requirements of the materials used in these connecting mechanisms make it impossible to use larger torques to avoid phenomena such as fracture and deformation of the mechanisms. Therefore, the tensioning mechanism with adjustable torque has become the preferred tensioning method, but the adjustable torque wrench currently used has a large minimum torque range and a large volume, which is difficult to apply to the assembly of small medical devices. Contents of the invention [0003] The purpose of the present invention is to provide a tensioning mechanism with adjustable torque, which has a simple structure and is easy to operate, and solves th...
