[0002] The infrared rays generated by the infrared therapy device can pass through clothes, skin, and directly reach muscles and subcutaneous tissues to produce a thermal effect. It is an indispensable and important tool in medical care. The existing infrared therapy device mainly includes an infrared transmitter, an arm, and a base. The infrared transmitter is used to irradiate infrared rays. The arm is connected between the head and the base. The arm generally adopts a two-stage folding connection structure. The position of the head is adjusted by the arm. However, the existing infrared therapy devices generally have the defect that the infrared transmitter is not flexible in rotation and adjustment.

[0003] Joint shafts are commonly used in the joints of various types of equipment to facilitate the rotation of joints. The common joint shafts of infrared treatment devices are equipped with a push button to cooperate with the contraction of the spring, and a limit block is set inside the joint shaft. Under normal conditions, the limit block is limited and cannot rotate. After pressing the button, the limit block is offset and no longer has a limiting effect, and it can rotate freely.

[0004] However, during use, this type of joint shaft can only be rotated by pressing a button, and some one-handed operations cannot achieve rotation, which is not very convenient; at the same time, there is no resistance to adjustment after pressing the button, and fine rotation cannot be achieved.

[0032] The action principle of the joint axis part of the infrared therapeutic device of the present invention is as follows:

[0033] Under normal conditions, the joint shaft is assembled, the upper shell 1 of the joint shaft is closed with the lower shell 2 of the joint shaft, the upper shell 1 of the joint shaft is fixedly installed with the upper branch pipe 3 through the upper shell installation groove 13, the lower shell 2 of the joint shaft is fixedly installed with the lower branch pipe 4 through the lower shell installation groove 22, and the two ends of the positioning shaft 61 are connected to the positioning hole 12 and the positioning column 62.

At this time, the joint shaft can be rotated unidirectionally, that is, the joint shaft can be rotated directly. Since the upper shell 1 of the joint shaft is meshed with the one-way clutch gear 51 of the rotating shaft core 5 through the tooth groove 11, and since one direction of the teeth of the one-way clutch gear 51 and the tooth groove 11 is a bevel, the one-way clutch gear 51 can be rotated unidirectionally clockwise. When the rotating shaft core 5 rotates clockwise, the rotating shaft core 5 has a displacement to the right, compressing the spring 6. When the one-way clutch gear 51 passes through a tooth groove 11, it is affected by the elastic force of the spring 6 and presses the one-way clutch gear 51 back to the tooth groove 11. The process is repeated, which is a unidirectional rotation process with a certain resistance.

[0034] When reverse rotation is required, the control block 7 is pressed, and the control block 7 presses the shaft core 5 to move to the right, so that the one-way clutch gear 51 disengages from the tooth groove 11, and the spur gear 52 on the right side of the shaft core 5 remains engaged with the rack 21, and free rotation in both directions is now possible.

[0035] The present application can realize unidirectional rotation with a certain resistance, and at the same time can enter a bidirectional rotation state through a button to realize a bidirectional rotation infrared treatment device, which is convenient for adjusting the irradiation position and direction.

[0036] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
