Abstract
Description
Technical Field
[0001] This invention relates to the field of spectrum therapy technology, specifically to a high-lifespan folding joint for spectrum therapy devices and its usage method. Background Technology
[0002] The spectrum therapy device is based on the principle of electromagnetic wave radiation. When the spectrum radiation plate is heated, it excites electromagnetic waves of a specific wavelength. These electromagnetic waves can penetrate the breathable plate and irradiate the surface of the human body. When the frequency of the electromagnetic waves is close to the inherent frequency of human tissue cells, a benign matching absorption effect will be produced, which in turn triggers the deep biological thermal and non-thermal effects of human tissue, effectively improving local blood circulation and promoting metabolism.
[0003] Existing spectrum therapy devices adopt an integrated structural design, which ensures structural stability, but also results in a large and cumbersome device size. When not in use, the huge size makes it extremely inconvenient to carry and store the device, requiring a large dedicated platform or space, which wastes space and makes it inconvenient to carry.
[0004] To address the aforementioned issues of bulkiness and portability, existing technologies incorporate folding structures into spectrum therapy devices. However, most current folding connection methods are quite simple, typically relying on ordinary pins or hinges for connection. This lack of effective damping control mechanisms results in insufficient frictional reaction force between components during folding, leading to a loose feel. Furthermore, after folding, the lack of sustained resistance means that the folding arm is prone to loosening and unfolding due to gravity or slight shaking during handling or storage, making it impossible to maintain a compact storage state. Sudden unfolding could even pinch fingers or damage the device. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a high-lifespan folding joint for a spectrum therapy device and its usage method, which solves the problems of the large size of the spectrum therapy device causing inconvenience in carrying and storing, and the loosening and unfolding of existing folding products after folding due to movement.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a high-lifespan folding joint for a spectrum therapy device, comprising a first outer shell, second outer shells on both the left and right sides of the first outer shell, a folding mechanism on the outer side of the first outer shell for facilitating the folding of the spectrum therapy device, and a locking mechanism on the front right side of the first outer shell for facilitating locking the unfolding angle of the spectrum therapy device during treatment. The folding mechanism includes support rods, and multiple support rods are respectively fixedly connected to the left and right ends inside the first outer shell and one side of the second outer shell. Each of the left and right ends of the multiple support rods is fixedly connected to a joint connecting rod 1. The multiple joint connecting rods 1 are respectively engaged with the second outer shell and the first outer shell. The front, rear, left and right ends of the first outer shell are provided with joint outer shells. One side of the joint connecting rod 1 is provided with a wire-passing damping pivot. The inside side of the joint outer shell is fixedly connected to a joint connecting rod 2. The wire-passing damping pivot is fixedly connected to the joint connecting rod 2. One side of the joint outer shell is fixedly connected to a joint end cap.
[0007] Preferably, the locking mechanism further includes a fixed bracket, which is fixedly connected to the rear wall of the right front joint end cap. A push rod is fixedly connected to the inner side of the fixed bracket. The output end of the push rod passes through the fixed bracket and makes linear contact with the locking plate. The outer wall of the locking plate has slots on both the left and right sides. Insert rods are fixedly connected to the front walls of the two joint connecting rods one on the right front end. The outer side of the insert rod passes through the through-line damping shaft and the joint connecting rod two in sequence and is inserted into the slot.
[0008] Preferably, the locking mechanism further includes a button, which is disposed on the joint end cap and contacts the push rod plane.
[0009] Preferably, the folding mechanism further includes a plurality of handle slots, which are respectively opened on the front and rear sides of the second outer shell and the first outer shell.
[0010] Preferably, a ring is fixedly connected to the top inner side of both the outer shell 1 and the outer shell 2, and a spectrum radiation plate is fixedly connected to the bottom of the ring.
[0011] Preferably, both the bottom of the outer shell and the outer shell are fixedly connected to a ventilated plate.
[0012] Preferably, the top of the outer casing one is provided with a groove, and the size of the groove matches the size of the top of the outer casing two.
[0013] Preferably, temperature sensors are fixedly connected to the inner sides of both the outer casing one and the outer casing two, and the temperature sensors are electrically connected to the spectrum radiation plate.
[0014] Preferably, the size of the second outer shell matches the size of the first outer shell.
[0015] A method for using a high-lifespan folding joint with a spectrum therapy device includes the following steps: S1: When the spectrum therapy device is not needed, press the button 35 on the surface of the joint end cover 26. After the button 35 is triggered, push the push rod 31. The output end of the push rod 31 pushes the locking plate 32 to move, so that the slot on the locking plate is disengaged from the locking teeth of the plug 34 fixed on the joint connecting rod 1. Then, apply force to the handle slot to rotate the outer shell 2 on both sides relative to the outer shell 1. During the rotation, the through-line damping shaft applies a reaction force damping to the joint connecting rod 1. The operator needs to overcome the damping force to rotate the outer shell 2 until the outer shell 2 is embedded in the groove opened on the top of the outer shell 1. Use the static friction of the through-line damping shaft to maintain the folded state. S2: When the spectrum therapy device is needed, rotate the outer shells on both sides outward to the predetermined angle. The locking plate (32) moves automatically under the action of the spring on the guide post of the joint link (25), so that the slot on the locking plate engages with the locking teeth of the plug fixed on the joint link, thereby locking the opening angle between the outer shell and the outer shell. S3: When the power is turned on, the spectrum radiation plate heats up and generates electromagnetic waves. The electromagnetic waves irradiate the human body through the breathable plate for treatment. At the same time, the temperature sensor detects the temperature of the spectrum radiation plate in real time. When the detected temperature exceeds the set threshold, the temperature sensor sends a command to reduce the working power of the spectrum radiation plate.
[0016] This invention provides a high-lifespan folding joint for a spectrum therapy device and its method of use. It has the following beneficial effects: 1. This invention rotates the outer shell two by turning the handle groove. During the rotation, the through-line damping shaft applies a reaction force to the rotation of the joint link one, so that after the outer shell two rotates to fit with the outer shell one, the through-line damping shaft can continuously provide resistance, which greatly reduces the size of the spectrum therapy device, makes it easier to store the spectrum therapy device, and avoids the outer shell two from loosening or falling apart due to handling after folding, thus improving the portability of the spectrum therapy device.
[0017] 2. When the preset folding angle is reached, the spring on the guide post of the joint link two causes the locking plate to move automatically. The locking plate uses a slot to engage with the locking teeth of the plug fixed on the joint link one, thereby restricting the rotation of the plug and the joint link one. This can firmly lock the angle formed by the outer shell one and the outer shell two, preventing the outer shell two from accidentally closing or shifting its angle during use, thus ensuring the stability of the treatment process.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Example 1: Reference Figure 2 , Figure 4 and Figure 6 This invention provides a high-lifespan folding joint for a spectrum therapy device, including a housing 1, with housing 2 4 on both the left and right sides of the housing 1, a folding mechanism 2 on the outer side of the housing 1, the folding mechanism 2 being used to facilitate the folding of the spectrum therapy device, and a locking mechanism 3 on the front right side of the housing 1, the locking mechanism 3 being used to conveniently lock the unfolding angle of the spectrum therapy device during treatment. The folding mechanism 2 includes support rods 21, which are fixedly connected to the left and right ends of the inner shell 1 and one side of the outer shell 4. Each of the left and right ends of the support rods 21 is fixedly connected to a joint connecting rod 22, which engages with the outer shell 4 and the outer shell 1. The front, rear, left, and right ends of the outer shell 1 are each provided with a joint shell 23. One side of each joint connecting rod 22 is provided with a wire-passing damping pivot 24, which provides resistance to prevent the outer shell 4 from opening during transport. One side of the inner side of the joint shell 23 is fixedly connected to a joint connecting rod 25. The wire-passing damping pivot 24 is connected to the joint connecting rod 25. 25. A joint end cap 26 is fixedly connected to one side of the joint shell 23. The joint end cap 26 is used to seal the joint shell 23. The folding mechanism 2 also includes multiple handle slots 27. The multiple handle slots 27 are respectively opened on the front and rear sides of the second shell 4 and the first shell 1. The top of the first shell 1 is provided with a groove 8. The size of the groove 8 matches the size of the top of the second shell 4. The groove 8 allows the second shell 4 to fit tightly with the first shell 1 when folded. The size of the second shell 4 matches the size of the first shell 1, so that after the second shell 4 is folded, the spectrum therapy device can form a regular cube, which is convenient for storage. Specifically, when the spectrum therapy device is not needed, the user presses the button 35 located on the surface of the joint end cap 26. After the button 35 is triggered, it pushes the push rod 31. The output end of the push rod 31 pushes the locking plate 32 to move, causing the slot 33 on the locking plate 32 to disengage from the locking teeth of the insert 34 fixed on the joint connecting rod 22. Then, the user holds the handle slot 27 on the surface of the outer shell 2 4 and the outer shell 1, applying external force to flip one side of the outer shell 2 4 upwards and the other side of the outer shell 2 4 downwards. During the displacement and rotation of the outer shell 2 4, the outer shell 2 4 drives the support rod 21 to rotate synchronously with the joint connecting rod 22. The joint connecting rod 22 then drives the through-wire damping shaft 24 to rotate. Since one end of the through-wire damping shaft 24 is fixed to the joint connecting rod 25 located inside the joint outer shell 23, the through-wire damping shaft... When the 24 is rotated under force, it will generate a reverse torque resistance on the joint link 22. During the continuous rotation of the outer shell 2 4, the operator will continuously apply force to overcome the damping force generated at the joint link 22 until the outer shell 2 4 on both sides is fully rotated into place and respectively fits against the upper and lower surfaces of the outer shell 1. When the folding action is terminated, the through-line damping shaft 24 continues to apply static friction resistance to the joint link 22. In this way, in the folded state, it can prevent the outer shell 2 4 from loosening and spreading due to shaking during handling or gravity, realizing the rapid folding and storage of the spectrum therapy device, effectively reducing the overall volume occupied by the device, and facilitating subsequent transportation and storage. At the same time, when folded into place, the edge structure of the outer shell 2 4 is precisely embedded in the pre-set groove 8 on the top of the outer shell 1, realizing a tight engagement between the outer shell 1 and the outer shell 2 4.
[0022] Reference Figure 7 , Figure 8 and Figure 9 The locking mechanism 3 also includes a fixed bracket 36, which is fixedly connected to the rear wall of the right front joint end cap 26. A push rod 31 is fixedly connected to the inner side of the fixed bracket 36. The output end of the push rod 31 passes through the fixed bracket 36 and linearly contacts the locking plate 32. The push rod 31 can push the locking plate 32 to move. The outer wall of the locking plate 32 has slots 33 on both the left and right sides. The front walls of the two joint connecting rods 22 on the right front are fixedly connected to insert rods 34. The outer side of the insert rod 34 passes through the through-line damping shaft 24 and the joint connecting rod 25 in sequence and is inserted into the slot 33. The angle of the insert rod 34 can be fixed when it is inserted into the slot 33. The locking mechanism 3 also includes a button 35, which is set on the joint end cap 26. The button 35 is in plane contact with the push rod 31. Pressing the button 35 can push the push rod 31. Specifically, when the spectrum therapy device is needed for treatment, first rotate the outer shells 4 on both sides to unfold them. When the outer shells 4 on both sides are unfolded to a predetermined angle, the locking plate 32 moves automatically under the action of the spring on the guide post of the joint link 25, so that the slot 33 on the locking plate 32 engages with the locking teeth of the insertion rod 34 fixed on the joint link 12, thereby restricting the rotational freedom of the insertion rod 34 and rigidly fixing the relative angle of the joint link 122. This locks the unfolding angle between the outer shell 4 and the outer shell 1, preventing the outer shell 4 from accidentally closing due to external force during subsequent use, and ensuring the stability of the user during treatment.
[0023] Reference Figure 1 , Figure 3 and Figure 5 A circular ring 5 is fixedly connected to the top inner side of both outer shell 1 and outer shell 2. A spectrum radiation plate 6 is fixedly connected to the bottom of the circular ring 5. A breathable plate 7 is fixedly connected to the bottom of both outer shell 1 and outer shell 2. A temperature sensor 9 is fixedly connected to the inner side of both outer shell 1 and outer shell 2. The temperature sensor 9 is electrically connected to the spectrum radiation plate 6. When the temperature sensor 9 detects that the temperature is too high, it will reduce the working frequency of the spectrum radiation plate 6 to avoid burns to the patient. Specifically, when a user undergoes rehabilitation treatment, the power is turned on, causing the spectrum radiation plate 6 to heat up. The heated spectrum radiation plate 6 then emits electromagnetic waves of a specific wavelength. These electromagnetic waves penetrate the breathable plate 7 and radiate onto the surface of the affected area. At this time, the human tissue cells produce a matching absorption effect on the electromagnetic waves, completing the physiotherapy work for the patient through the biothermal effect. Simultaneously, throughout the entire treatment cycle, the internal temperature sensor 9 continuously monitors the real-time operating temperature of the spectrum radiation plate 6. Once the temperature value of the spectrum radiation plate 6 exceeds the safety threshold, the temperature sensor 9 immediately feeds back a signal and issues a control command, automatically adjusting the circuit to reduce the operating power of the spectrum radiation plate 6, thereby reducing the radiation temperature and preventing burns to the patient's skin due to excessive temperature.
[0024] A method for using a high-lifespan folding joint with a spectrum therapy device includes the following steps: S1: When the spectrum therapy device is not needed, press the button 35 on the surface of the joint end cover 26. After the button 35 is triggered, push the push rod 31. The output end of the push rod 31 pushes the locking plate 32 to move, so that the slot 33 on the locking plate 32 disengages from the locking teeth of the plug 34 fixed on the joint connecting rod 1 22. Then, apply force to the handle slot 27 to rotate the outer shell 2 4 on both sides relative to the outer shell 1. During the rotation, the through-line damping shaft 24 applies a reaction force damping to the joint connecting rod 1 22. The operator needs to overcome the damping force to rotate the outer shell 2 4 until the outer shell 2 4 is embedded in the groove 8 opened at the top of the outer shell 1. The static friction of the through-line damping shaft 24 is used to maintain the folded state. S2: When the spectrum therapy device is needed, rotate the outer shells 24 on both sides outward to the predetermined angle. The locking plate 32 moves automatically under the action of the spring on the guide post of the joint link 25, so that the slot 33 on the locking plate 32 and the locking teeth of the insert 34 fixed on the joint link 12 engage and lock each other, thereby locking the unfolding angle between the outer shell 24 and the outer shell 1. S3: Power is turned on, causing the spectrum radiation plate 6 to heat up and emit electromagnetic waves. The electromagnetic waves irradiate the human body through the breathable plate 7 for treatment. At the same time, the temperature sensor 9 monitors the temperature of the spectrum radiation plate 6 in real time. When the detected temperature exceeds the set threshold, the temperature sensor 9 sends a command to reduce the operating power of the spectrum radiation plate 6. Working principle: When the spectrum therapy device is not needed, pressing the button 35 on the surface of the joint end cap 26 triggers the push rod 31, which in turn pushes the locking plate 32 to move. This causes the slot 33 on the locking plate 32 to disengage from the locking teeth of the insert rod 34 fixed to the joint connecting rod 22. Then, the handle slot 27 on the outer shell 2 4 and the outer shell 1 is turned to rotate one side of the outer shell 2 4 upwards and the other side downwards. During this rotation, the outer shell 2 4 drives the support rod 21 and the joint connecting rod 22 to rotate simultaneously, which in turn drives the through-wire damping shaft 24 to rotate. Since the through-wire damping shaft 24 is fixed to the joint connecting rod 25 inside the joint outer shell 23, the through-wire damping shaft 24 rotates. When the linear damping shaft 24 rotates, it provides a reaction force to the joint link 22. During the rotation of the outer shell 4, the operator needs to overcome the resistance generated by the joint link 22 until the outer shell 4 on both sides rotates to fit with the upper and lower sides of the outer shell 1. After the rotation is completed, the linear damping shaft 24 will continue to apply resistance to the joint link 22. This can prevent the outer shell 4 from spreading out due to movement after folding. It can be easily folded when not in use, which greatly reduces the size of the spectrum therapy device and makes it easier to store the spectrum therapy device. When folded, the outer shell 4 can fit into the groove 8 opened on the top of the outer shell 1, so that the outer shell 1 and the outer shell 4 can fit tightly together. Furthermore, when the spectrum therapy device is needed for treatment, the outer shells 2 and 4 on both sides are rotated and unfolded. When the outer shells 2 and 4 on both sides are fully unfolded, the locking plate 32 moves automatically under the action of the spring on the guide post of the joint connecting rod 25, so that the slot 33 on the locking plate 32 and the locking teeth of the insert rod 34 fixed on the joint connecting rod 1 are engaged and locked together, which can restrict the rotation of the insert rod 34, thereby fixing the relative angle of the joint connecting rod 122, and fixing the angle formed by the outer shell 2 and 1, preventing the outer shell 2 and 4 from closing during use, making it convenient for the user to carry out treatment. Finally, when the user is receiving treatment, the spectrum radiation plate 6 can generate heat and emit electromagnetic waves. These electromagnetic waves can irradiate the human body through the breathable plate 7. At this time, the human tissue will absorb the electromagnetic waves, thereby completing the treatment for the patient. During the treatment, the temperature sensor 9 can continuously detect the temperature of the spectrum radiation plate 6. When the temperature of the spectrum radiation plate 6 is too high, the temperature sensor 9 can issue a command to reduce the working power of the spectrum radiation plate 6 to avoid burning the patient due to excessive temperature.
