[0088] Example 4

[0089] The double-headed vertical heating lamp physiotherapy device provided in Examples 1-3 which is easy to adjust is further optimized. Specifically, Figure 1-Figure 12 As shown, the wheel axle locking assembly 8 includes an axle brake ring 81, which is hinged on the lower side of the central axis of the moving wheel 12, and a spring positioning cylinder 82 is provided above the top surface of the end of the wheel axle brake ring 81 away from the hinge point, and a separation spring 83 is provided inside the spring positioning cylinder 82, and the bottom end of the separation spring 83 abuts against the top surface of the wheel axle brake ring 81, and a brake wheel wire 84 is connected to the top surface of the wheel axle brake ring 81 away from the separation spring 83. The brake wheel wire 84 is penetrated at the center of the counterweight rod 11 and extends to the inside of the sliding cavity 13, and one end of the brake wheel wire 84 located inside the sliding cavity 13 is fixed to the outer wall of the limit transmission block 211.

[0090] A wheel axle locking assembly 8 is provided at the position where the counterweight moving frame 1 is connected to the moving wheel 12. When the baking lamp is in use, the lifting control box 3 can be raised to drive the transmission wire 25, drive the wheel axle brake ring 81 to rotate, and lock the wheel axles of all the moving wheels 12 to fix the counterweight moving frame 1 and ensure the stability and safety of the baking lamp.

[0091] The use process of the double-head vertical heating lamp physiotherapy device which is easy to adjust provided by the present invention is as follows:

[0092] Pull the three-section arm 4 or the lifting mounting seat 2 to slide the counterweight movable frame 1 through the movable wheel 12 to the position where the electromagnetic heating lamp instrument 5 needs to be used, and then the upper and lower angles of the electromagnetic heating lamp instrument 5 can be adjusted by rotating the three-section arm 4.

[0093] When the three-section arm 4 is rotated, the convex plate 611 and the limiting tooth block 621 at the bottom ends of the third section 43 and the second section 42 will rotate.

[0094] The rotation of the convex plate 611 will drive the tension spring fixing blocks 612 connected at both ends to move. When the tension spring moving block moves, the rotation of the convex plate 611 will stretch the tension spring, so that the arm located above has the pulling force to reset.

[0095] The rotation of the limiting tooth block 621 will apply a thrust to the engaging locking block 624 engaged with its outer wall. The engaging locking block 624 will slide toward the inside of the contraction groove 622 under the thrust and apply pressure to the third spring 623. When the limiting tooth block 621 has completed its rotation, the third spring 623 will apply a thrust to the engaging locking block 624, allowing the engaging locking block 624 to engage and position the rotated limiting tooth block 621, thereby fixing the three-section arm 4 and maintaining the adjusted posture. The cooperation between the arm stretching member 61 and the arm limiting member 62 can enhance the bearing capacity of the three-section arm 4 and ensure the stability of the electromagnetic heating lamp 5 during operation.

[0096] When the electromagnetic heating lamp instrument 5 is adjusted in rotation angle, the three-section arm 4 can be directly rotated to drive the lifting control box 3 to rotate through the three-section arm 4. The rotation of the lifting control box 3 will drive the cross bar 33 to rotate. The rotation of the cross bar 33 will drive the lifting slide bar 22 to rotate through the lifting slide slot 221. The rotation of the lifting slide bar 22 will drive the limiting protrusion 224 coaxially connected thereto to rotate. The rotation of the limiting protrusion 224 will drive the side gear ring 245 to rotate. When the side gear ring 245 rotates, it will apply a thrust to the positioning tooth 244. The positioning tooth 244 is subjected to the thrust and will push the positioning lock block 243 to slide down. The sliding of the positioning lock block 243 will apply pressure to the first spring 237. When the rotation angle adjustment of the limit electromagnetic heating lamp instrument 5 is completed, the first spring 237 will apply a thrust to the positioning lock block 243, so that the positioning tooth 244 is engaged with the side gear ring 245, so as to realize the engagement and locking of the lifting slide bar 22, thereby ensuring the stability of the electromagnetic heating lamp instrument 5 after the rotation angle adjustment.

[0097] When the height of the electromagnetic heating lamp instrument 5 is insufficient, the lifting control box 3 can be started. At this time, the driving motor 75 drives the climbing shaft 7 to rotate synchronously. The rotation of the climbing shaft 7 will drive the rubber interlocking wheel 71 and the interlocking semicircular wheel 72 connected to its outer wall to rotate. When the rubber interlocking wheel 71 and the interlocking semicircular wheel 72 rotate, the lifting control box 3 will be thrust by the climbing shaft 7 and gradually slide to the top of the lifting slide bar 22. When the electromagnetic heating lamp instrument 5 moves to the required position, the driving of the driving motor 75 can be stopped (the output end of the driving motor 75 is equipped with a shaft lock. After stopping, the shaft lock loses power and locks the output shaft to prevent the lifting control box 3 from moving downward).

[0098] In this state, when the annular temperature sensor 53 senses that the temperature is too high, it can continue to rise, and when it senses that the temperature is too low, it can drive the electromagnetic heating lamp 5 to move downward.

[0099] When the lifting control box 3 moves up, the cross bar 33 inside the lifting control box 3 will pull the transmission wire 25, so that the other end of the transmission wire 25 is subjected to tension. The counterweight moving frame 1 connected to the other end of the transmission wire 25 is on the ground and cannot move up. The tension output by the transmission wire 25 will pull the vertical rod 21 and the limit transmission block 211 at the bottom end of the lifting mounting seat 2 to slide toward the inner bottom of the sliding cavity 13. When the limit transmission block 211 slides, it will output tension to the multiple sets of brake wheel wires 84 connected to its outer wall. The brake wheel wire 84 is pulled and the wheel axle brake ring 81 is pulled upward around the hinge point. When the wheel axle brake ring 81 moves upward, it will fit with the wheel axle on one side of the moving wheel 12. At this time, the wheel axle of the moving wheel 12 is subjected to the friction force of the fit and the moving wheel 12 is locked.

[0100] When the limit transmission block 211 slides down to the bottom surface of the sliding cavity 13, it will exert pressure on the return spring 215 and the transmission wire 25 can no longer continue to exert a downward force on the vertical rod 21. At this time, as the lifting control box 3 continues to move upward, the tension exerted on the transmission wire 25 will exert force on the wire sliding shaft 236 of the wire winding part in the lifting mounting seat 2. The force exerted on the wire sliding shaft 236 will push the first spring 237 to contract, allowing the two adjacent staggered wire sliding shafts 236 to gradually move, so that the transmission wire 25 elastically received by the wire sliding shaft 236 is released, which is used to release the lifting control box 3.

[0101] It should be noted that the length of the steel wire stored in the steel wire storage portion 23 is equal to or greater than the distance that the lifting slide bar 22 can slide.

[0102] It should be noted that: no matter the lifting control box 3 is moved up manually or automatically by the device, the moving wheel 12 will be locked to ensure the stability of the device when it is started, and the lifting control box 3 needs to be reset after use.

[0103] After the electromagnetic heating lamp 5 is adjusted, the electromagnetic heating lamp 5 can be started by the control button on the outer side of the lifting control box 3. When the electromagnetic heating lamp 5 is started, the required time of electric therapy and magnetic therapy can be freely set.

[0104] The setting of the double-headed electromagnetic heating lamp 5 can increase the area of ​​electric therapy and magnetic therapy, improve the convenience and functionality of use, and has a locking function when adjusted at any angle, which is conducive to improving the control effect of placement and adjustment.

[0105] It should be noted that the engaging semicircular wheel 72 is made of rubber, and the engaging semicircular wheel 72 and the lifting slide bar 22 fit together to generate sufficient friction to enable the lifting control box 3 to move upward.

[0106] It should be noted that the annular temperature sensor 53 itself is a temperature sensor, which can convert the sensed temperature into a signal that can be used for output. After the annular temperature sensor 53 converts the sensed temperature into a signal, it is transmitted to the control system of the lifting control box 3 through electrical transmission or wireless transmission. The control system can drive the electromagnetic heating lamp 5 to move up and down (it cannot move downward when it is at the bottom) by starting the drive motor 75 to rotate forward and reverse.

[0107] After the equipment is used, the electromagnetic heating lamp 5 will automatically turn off after the timing is over, and the lifting control box 3 will be in its original position. At this time, manual control or remote software program is required to connect to the internal operating system of the lifting control box 3 to control the lifting control box 3 to move downward to automatically complete the reset of the electromagnetic heating lamp 5.

[0108] The present invention has an efficient adjustment method and a locking function after adjustment, which can lock the electromagnetic heating lamp 5 at a position where electrotherapy and magnetic therapy are required, thereby improving the convenience of use and adjustment of the electromagnetic heating lamp 5. At the same time, the locking function can also improve the safety of electrotherapy and magnetic therapy.

[0109] The design of the annular temperature sensor 53 and the axle locking assembly 8 can enhance the comfort of electrotherapy and magnetic therapy as well as the safety factor during the electrotherapy and magnetic therapy.
