Rib rolling instrument

Abstract

The invention relates to the technical field of physiotherapy instruments, and discloses a rib rolling instrument which comprises a motor support. A stepping motor is fixed to the surface of a motor support, the output end of the stepping motor is connected with a ball screw through a coupler, and the two ends of a lead screw shaft are fixedly supported by a lead screw support and a second lead screw support. When the stepping motor operates, the ball screw is driven to rotate through the coupler, so that the sliding block in threaded connection with the ball screw slides in the axial direction of the ball screw; the pressure sensor module on the top of the sliding block synchronously moves along with the sliding block to drive the roller support to move. A steel shaft on the inner wall of the roller support is connected with a polyurethane roller through a bearing, and the polyurethane roller makes contact with the PU cover in the moving process to achieve the rolling massage action. And meanwhile, the screw shaft sleeve on the outer wall of the screw shaft synchronously slides along with the pressure sensor module to assist in stabilizing the motion trail. The pressure sensor module monitors the pressing force of the polyurethane roller in real time, and a protection mechanism can be triggered when the pressure is abnormal.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of physiotherapy equipment, and particularly relates to a muscle rolling instrument. BACKGROUND

[0002] The muscle rolling massage instrument is a device applied to physiotherapy and relaxation, which is usually used to relieve muscle fatigue, promote blood circulation and even help alleviate some chronic pain through massage. Its background technology involves multiple fields, including massage technology, electronic control technology, sensor technology, etc.

[0003] The muscle rolling massage device in the prior art is mostly manually used by manpower, and some only rely on mechanical structure or simple switch control of massage intensity, lacking high-precision pressure sensors and intelligent feedback, and being unable to monitor the pressing intensity in real time, so as to automatically adjust or pause when the pressure exceeds the safety threshold, resulting in the risk of excessive pressure, and thus the following problems exist: lacking effective pressure protection mechanism, easily causing muscle injury due to excessive pressure, and poor rolling movement stability, affecting the massage effect and use comfort.

[0004] The same products on the current market are either fixed large devices or manually operated instruments, which have obvious inconvenience in use, and often need the user to actively adapt to the fixed form and operation logic of the device, and the device cannot make adaptive adjustment according to the needs of the user.

[0005] The product of the present application breaks through this limitation: in the use process, the user only needs to adjust the body posture, and can realize massage of different parts and different intensity by means of the device. This design gives the user stronger autonomy, so that he does not need to be subject to the fixed mode of the device itself, thereby obtaining more flexible and individualized use experience.

[0015] Through the above technical scheme, the power line is connected to the power supply, and the controller starts the system. The user sets the parameters through the key module on the top of the upper cover, and the instruction is transmitted to the controller. When the stepping motor is running, the ball screw is driven to rotate through the coupling, the ball screw is rotatably connected to the screw support through bearing two, the snap spring baffle on the outer wall limits the axial displacement, and the connection between the lower cover inner wall and the upper cover inner wall bottom is completed through the bolt penetrating the lower cover inner wall and being threadedly connected.
