Automatic tension adjustment device for thermotherapy instrument

Abstract

An automatic tension adjustment device for a thermotherapy instrument is provided, comprising: a transfer member (10); a power transmission member (20) connected to the transfer member and transmitting power to the transfer member (10) through a driving device (40); A tension adjusting device (30) installed on the transfer member (10) to adjust and maintain the tension of the power transmission member. Therefore, the present invention proposes an automatic tension adjustment device for a thermotherapy instrument. The tension adjustment device pulls the power transmission member to a slack length and maintains the tension of the power transmission member at a constant level, so that the transfer work of the transfer member can be performed smoothly. Reduce power loss, prevent friction noise caused by power transmission components and impact noise due to contact with the ground. Moreover, the tension of the power transmission member is prevented from increasing unnecessarily, so as to prevent shrinkage deformation and twist deformation of the housing of the thermotherapy device.

Description

technical field [0001] The present invention relates to an automatic tension adjusting device for a thermotherapy apparatus, in which a massage appliance is installed, a transfer member that moves in a forward / rearward direction is provided, and a power transmission member installed on the transfer member for transmitting power to the transfer member , where chains, timing belts, ropes or wires are used as power transmission members. If the power transmission member sags or loosens due to long-term use of the instrument and is released, the tension adjustment device pulls the power transmission member to the released length and maintains the tension of the power transmission member at a constant level, so that the transfer work of the transfer member can be carried out smoothly, Reduce power loss, prevent friction noise caused by power transmission components and impact noise due to contact with the ground. Moreover, the tension of the power transmission member is prevented f...

Problems solved by technology

[0005] However, in the prior art, because the workers need to use tools to turn the screw heads to adjust the tension of the timing belt, the number of workers increases

In addition, when the timing belt is slack during instrument actuation, it is necessary to stop the device actuation to adjust the tension of the timing belt, thus causing inconvenience in use

[0006] In addition, when the device is actuated in a state where the tension of the timing belt is not adjusted by additional work, power transmission through the timing belt cannot be performed smoothly, and when the timing belt sags or is weak, the timing belt may be disconnected from the belt connected to the timing belt. Sprocket or pulley disengages and thus releases
