Automatic tension controlling apparatus for thermotherapy device

Abstract

The present invention relates to an automatic tension controlling apparatus for a thermotherapy device, and more specifically, an automatic tension controlling apparatus for a thermotherapy device, comprising: a transport member (10); a driving force transferring member (20), connected to the transport member (10), for transferring driving force to the transport member (10) through a driving means (40); and a tension control means (30), coupled to the transport member (10), for maintaining and controlling the tension of the driving force transferring member. As a result, the present invention provides the automatic tension controlling apparatus in which the driving force transferring member for transferring driving force to the transferring member transfers driving force by being coupled to the transport member, and when the driving force transferring member becomes lax due to extension or loosening from long-term use when an option such as a chain, a timing belt, a rope, or a steel wire is used as the driving force transferring member, the tension control means controls so that tension is maintained at a constant level by pulling the driving force transferring member as much as the length that is loosened, thereby enabling smooth transport work by the transport member, reducing loss of driving force, preventing friction noise due to the driving force transferring member or shock noise from coming into contact with a bottom surface, and prevents unnecessary increase of tension in the driving force transferring member to prevent deformation of a housing of the thermotherapy device due to contraction or distortion.

Description

Technical field [0001] The present invention relates to an automatic tension adjustment device for a thermal treatment instrument, in which a massage appliance is installed, a transfer member that moves in the forward / backward 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 steel wires are used as power transmission members. If due to the long-term use of the instrument, the power transmission member sags or slack and is released, the tension adjusting 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 performed smoothly. Reduce power loss, prevent friction noise caused by power transmission components and impact noise caused by contact with the ground. Moreover, the tension of the power transmission member...

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
