Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a cantilever structure of a red light therapeutic apparatus. Background Art

[0002] Red light therapy device is a new type of phototherapy equipment that can be used in hospitals and families. Its basic principle is to obtain red visible light bands mainly in the range of 600-700nm through special filters. This band has deep penetration into the human body and better curative effect. The spot size is large (equivalent to hundreds of times that of He-Ne laser), providing a better treatment method for treating some large-area diseases.

[0003] The red light therapy device treats the affected area by controlling the red light lamp to irradiate it. The cantilever is the connecting structure between the red light lamp and the device body, and is mainly used to adjust the direction and position of the red light lamp.

[0004] The cantilever of the existing red light therapy device has certain defects. Most of the existing red light therapy devices have a main body and a red light lamp directly connected through an external data cable. The data cable is in a suspended state. The data cable in this state is very easy to be touched during the displacement of the cantilever or the activities of people, which will cause the red light lamp to move under force and produce irradiation deviation, which can easily cause damage to non-affected areas and affect the treatment effect of the affected area. Therefore, a cantilever structure of a red light therapy device is now proposed. Utility Model Content

[0006] In view of the above technical problems, the utility model provides a cantilever structure of a red light therapy device.

[0007] 2. Technical solution:

[0008] A cantilever structure of a red light therapy device comprises a first arm and a second arm, the first arm and the second arm are rotatably connected via a damping shaft, an extension rod is slidably connected inside the second arm, a red light lamp is provided at one end of the extension rod away from the first arm, a first shaft rod is rotatably connected to the damping shaft, the first shaft rod is rotatably connected to the second shaft rod via a first rotating shaft, the second shaft rod is rotatably connected to one end of the extension rod close to the first arm rod via a second rotating shaft, a data cable for data transmission or power connection is provided on the red light lamp, the data cable is led out through a wire groove inside the extension rod, the top of the second rotating shaft, the bottom of the first rotating shaft, the top of the damping shaft and the card slot inside the first arm and is fixed at the end of the first arm rod.

[0009] Furthermore, a third rotating shaft is fixed to one end of the extension rod away from the first arm rod, and the red light is rotatably connected to the third rotating shaft.

[0010] Furthermore, a mounting frame is fixed to one end of the extension rod close to the first arm, the second rotating shaft is arranged on the mounting frame, a sliding block is arranged on the mounting frame, and the sliding block is slidably connected to a sliding groove on the second arm.

[0015] 3. Beneficial effects:

[0016] In the utility model, a sliding and telescopic extension rod is provided, and the length of the extension rod through which the second arm rod is extended is adjusted according to the position of the patient's affected part, thereby adjusting the position of the red light lamp on the extension rod without moving the red light therapy device body. At the same time, during the adjustment process, the structure formed by the first shaft rod and the second shaft rod can ensure that the data cable is not in a loose state, thereby preventing the data cable from being accidentally touched and causing the red light lamp to change its irradiation angle.

[0017] In addition, the reinforcement ribs and the card slots are set up, and the setting of the reinforcement ribs enhances the structural strength of the first arm, improves the anti-bending effect, and avoids bending due to force during use or transportation. The design of multiple reinforcement ribs allows the internal card slots for storing data cables to be formed automatically, which can guide the internal data cables for routing while also limiting the internal data cables for protection, further avoiding the possibility of damage to the data cables by external forces.

DETAILED DESCRIPTION

[0024] The utility model is described in detail below in conjunction with the accompanying drawings.

[0025] As attached Figure 1 To Attachment Figure 5 As shown,

[0026] Embodiment 1:

[0027] A cantilever structure of a red light therapy device includes a first arm 1 and a second arm 6, the first arm 1 and the second arm 6 are rotationally connected via a damping shaft 5, an extension rod 8 is slidably connected inside the second arm 6, a red light lamp 17 is provided at one end of the extension rod 8 away from the first arm 1, a first shaft 12 is rotationally connected to the damping shaft 5, the first shaft 12 is rotationally connected to the second shaft 15 via a first rotating shaft 13, the second shaft 15 is rotationally connected to one end of the extension rod 8 close to the first arm 1 via a second rotating shaft, a data line 4 for data transmission or power connection is provided on the red light lamp 17, the data line 4 is sequentially led out through a wire groove 16 inside the extension rod 8, the top of the second rotating shaft, the bottom of the first rotating shaft 13, the top of the damping shaft 5 and the card slot 3 inside the first arm 1, and is fixed at the end of the first arm 1.

[0028] Embodiment 2:

[0029] A third rotating shaft 18 is fixed to one end of the extension rod 8 away from the first arm 1, and the red light lamp 17 is rotatably connected to the third rotating shaft 18. The height of the red light lamp 17 is adjusted by adjusting the angle between the first arm 1 and the second arm 6, the horizontal position of the red light lamp 17 is adjusted by adjusting the length of the extension rod 8 extending out of the second arm 6, and the red light lamp 17 is further rotated to adjust the elevation angle to change the irradiation direction of the red light lamp 17, so as to meet the need of irradiating the affected area during red light therapy.

[0030] Since the extension rod 8 will inevitably drag the data cable 4 during its sliding and retracting process, in order to avoid motion interference, it is necessary to reserve a section of the data cable 4 in a relaxed state to meet the extension and retraction requirements of the extension rod 8. On the one hand, the data cable 4 exposed to the outside is not beautiful and is easily damaged. On the other hand, the data cable 4 in a relaxed state is not easy to detect and is easily pulled and damaged by accidental touch, and may also cause the irradiation direction of the red light 17 to change. For this purpose, the first shaft rod 12 and the second shaft rod 15 are set. When the extension rod 8 slides, the extension rod 8 can pull the second shaft rod 15 to move, and then pull the first shaft rod 12, change the angle between the first shaft rod 12 and the second shaft rod 15, and thus change the length of the opposite side of the angle, so as to compensate for the length requirement of the data cable 4 when the extension rod 8 slides, and play a role in storage and tightening.

[0031] Embodiment 3:

[0032] A mounting frame 9 is fixed to one end of the extension rod 8 close to the first arm 1, and the second rotating shaft is arranged on the mounting frame 9. A slider 10 is arranged on the mounting frame 9, and the slider 10 is slidably connected to the slide groove 7 on the second arm 6. The extension rod 8 is guided and limited by the slider 10 and the slide groove 7.

[0033] Embodiment 4:

[0034] An adjusting knob is provided on the damping shaft 5, and the adjusting knob is threadedly connected to the damping shaft 5. The first arm 1 and the second arm 6 rotate around the damping shaft 5 to adjust the included angle, and the damping force of the damping shaft 5 is used for preliminary limiting, and then the adjusting knob can be turned to strengthen the damping force for better fixation.

[0035] Embodiment 5:

[0036] A plurality of reinforcing ribs 2 are provided on the first arm 1, and a slot 3 is formed between two adjacent reinforcing ribs 2. The slot 3 can perform routing and position limiting protection for the data cable 4 inside the slot to avoid damage by external forces. The provision of the reinforcing ribs 2 enhances the structural strength of the first arm 1, improves the anti-bending effect, and avoids bending due to force during use or transportation.

[0038] The first shaft rod 12 has first rings 11 at both ends, which are movably connected to the damping shaft 5 and the first rotating shaft 13 respectively; the second shaft rod 15 has second rings 14 at both ends, which are movably connected to the first rotating shaft 13 and the second rotating shaft respectively.

Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection defined by the claims of this application.
