[0032] As Figure 1 shown, the infrared therapeutic apparatus of this embodiment includes a cabinet 1, a lamp head 2 and a connecting arm 3. The lamp head 2 is arranged on the cabinet 1 through the connecting arm 3. The connecting arm 3 is a two-section structure, which can realize the adjustment of different irradiation angles and different irradiation ranges of the lamp head 2.

[0033] The cabinet 1 is provided with an operation table (not shown). The operation table includes a touch screen (or control buttons) and a control module electrically connected to the touch screen, and can control the energy wave emitting unit for emitting infrared rays arranged on the lamp head. There is no improvement in the structure of the operation table and the lamp head of the infrared therapeutic apparatus in this embodiment, and the conventional designs of existing infrared therapeutic apparatuses are adopted, so no further description will be given here.

[0034] One end of the connecting arm 3 is connected to the cabinet 1, and the other end is provided with the lamp head 2. By changing the rotation angle and the extension length of the connecting arm 3, the position of the lamp head 2 can be adjusted, and thus the irradiation range of the infrared rays can be changed. As Figure 2 、 Figure 3 and Figure 4As shown in the figure, the connecting arm 3 of this embodiment includes a lower arm 3-1, an upper arm 3-2, a lamp holder clamping and rotating assembly 3-3, an arm connecting seat 3-4, a first arm socket part 3-5, a second arm socket part 3-6, a first arm clamping part 3-7 and a second arm clamping part 3-8. The first arm socket part 3-5 and the second arm socket part 3-6 have the same structure, and the first arm clamping part 3-7 and the second arm clamping part 3-8 have the same structure.

[0035] The first end of the lower arm 3-1 is connected to the first arm socket part 3-5, and is connected to the cabinet 1 through the first arm socket part 3-5. The second end is connected to the first arm clamping part 3-7, and the first arm clamping part 3-7 is connected to the arm connecting seat 3-4. The first end of the upper arm 3-2 is provided with a second arm clamping part 3-8, and the lamp holder clamping and rotating assembly 3-3 is connected to the upper arm 3-2 through the second arm clamping part 3-8; the second end of the upper arm 3-2 is provided with a second arm socket part 3-6, and is connected to the lower arm 3-1 through the cooperation of the second arm socket part 3-6 and the arm connecting seat 3-4. The lamp head 2 is arranged on the lamp holder clamping and rotating assembly 3-3. The lower arm 3-1 can rotate around an axis extending in the vertical direction through the first arm socket part 3-5, and the upper arm 3-2 can rotate around an axis extending in the vertical direction through the second arm socket part 3-6.

[0036] A connecting arm support shaft (not shown) is provided on the cabinet 1, and the connecting arm support shaft extends in the vertical direction. The first arm socket part 3-5 is of a sleeve structure, sleeved on the connecting arm support shaft, and can rotate around the connecting arm support shaft, so that the lower arm 3-1 connected to the first arm socket part 3-5 can rotate around the connecting arm support shaft on the cabinet 1.

[0037] As an implementation manner, a positioning bolt 3-9 is provided on the first arm socket part 3-5 of this embodiment. A limiting groove is provided on the connecting arm support shaft. The limiting groove is an arc-shaped groove extending along the circumferential direction of the connecting arm support shaft. The height of the limiting groove corresponds to the height of the positioning bolt 3-9. The positioning bolt 3-9 passes through a threaded hole on the side wall of the first arm socket part 3-5, and the end extends into the limiting groove. When the positioning bolt 3-9 is tightened, the positioning bolt 3-9 presses against the connecting arm support shaft, which can limit the rotation of the first arm socket part 3-5, thereby playing a role in fixing the lower arm 3-1; when the positioning bolt 3-9 is loosened, the lower arm 3-1 can rotate freely in the horizontal direction (the first degree of freedom).

[0038] Optionally, the central angle of the limit groove is less than 360°, so that the limit groove can limit the movement range of the positioning bolt 3-9, and further limit the rotation range of the lower arm 3-1 (the first arm socket part 3-5), so that the lower arm 3-1 cannot rotate more than one week. This can avoid the winding of the wires tied to the connecting arm when the lower arm 3-1 rotates around the connecting arm support shaft for multiple weeks, affecting the movement adjustment of the connecting arm.

[0039] In this embodiment, the vertical cross-sectional shape of the first arm clamping part 3-7 is semi-I-shaped. A pair of through holes are processed in the first arm clamping part 3-7 at intervals in the vertical direction. The arm connecting seat 3-4 is connected to the first arm clamping part 3-7 through bolts passing through the through holes.

[0040] The arm connecting seat 3-4 has a bottom plate 3-4a that is clamped on the first arm clamping part 3-7 and connected to the first arm clamping part 3-7 through bolts, and a rotating shaft part 3-4b that is arranged on the bottom plate 3-4a and protrudes from the bottom plate 3-4a. The second arm socket part 3-6 is sleeved on the rotating shaft part 3-4b and can rotate around the rotating shaft part 3-4b. The structure of the rotating shaft part 3-4b is basically the same as that of the connecting arm support shaft on the cabinet 1, and both extend in the vertical direction. In this embodiment, a positioning bolt 3-9 is also provided on the second arm socket part 3-6, and a limit groove c with a central angle less than 360° is also provided on the rotating shaft part 3-4b. The positioning bolt 3-9 is screwed into the threaded hole on the second arm socket part 3-6, and the end passes through the threaded hole and extends into the limit groove c. When the positioning bolt 3-9 is tightened, the positioning bolt 3-9 presses against the rotating shaft part 3-4b, and the upper arm 3-2 (the second arm socket part 3-6) cannot rotate. When the positioning bolt 3-9 is loosened, the upper arm 3-2 (the second arm socket part 3-6) can freely rotate around the rotating shaft part 3-4b in the horizontal direction (the second degree of freedom), but is restricted by the limit groove c and cannot rotate more than one week.

[0041] The structure of the second arm clamping part 3-8 is the same as that of the first arm clamping part 3-7. The vertical cross-sectional shape is semi-I-shaped. A pair of through holes are processed in the second arm clamping part 3-8 at intervals in the vertical direction. The lamp head clamping and rotating assembly 3-3 is connected to the second arm clamping part 3-8 through bolts passing through the through holes.

[0042] Refer to Figures 5 to 10, the lamp holder clamping and rotating assembly 3-3 of this embodiment includes: a base 3-301, a rotating seat 3-302 and a lamp holder connecting plate 3-303. The base 3-301 is connected to the second arm clamping portion 3-8. The base 3-301 of this embodiment is generally in a Y shape, having a body 3-301a connected to the second arm clamping portion 3-8 and a pair of arm portions 3-301b connected to the body 3-301a. The arm portions 3-301b extend forward from the body 3-301a. A through hole is machined on the body 3-301a and is connected to the second arm clamping portion 3-8 through a bolt passing through the through hole. Through holes are also machined on the arm portions 3-301b. The axial direction of the through holes on the arm portions 3-301b is perpendicular to the axial direction of the through holes on the body 3-301a. The axial direction of the through holes on the arm portions 3-301b is horizontal, and the axial direction of the through holes on the body 3-301a is vertical, so that the lamp holder clamping and rotating assembly 3-3 can be rotated in two perpendicular directions.

[0043] One end of the rotating seat 3-302 can be inserted between the two arm portions 3-301b of the base 3-301. For the convenience of description, the end of the rotating seat 3-302 inserted between the arm portions 3-301b is defined as the head of the rotating seat 3-302. As Figure 11 and Figure 12 shown, the rotating seat 3-302 has a head 3-302a and a pair of clamping arms 3-302b connected to the head 3-302a. The clamping arms 3-302b are machined with inner cavities having a semicircular cross-sectional shape, and the extending direction of the inner cavities is the same as the extending direction of the clamping arms 3-302b. The inner cavities on the two clamping arms 3-302b are combined together to form an inner cavity with a circular cross-sectional shape. A clamping and fixing portion 3-302c is correspondingly arranged on each clamping arm 3-302b. A threaded hole is machined on the clamping and fixing portion 3-302c. Through the cooperation of a bolt and the threaded hole on the clamping and fixing portion 3-302c, the two clamping arms 3-302b can be clamped.

[0044] A rotating shaft hole a extending in the horizontal direction is provided on the head 3-302a of the rotating seat 3-302. The fixed rotating shaft 3-304 passes through the through hole on the arm portion 3-301b and the rotating shaft hole a on the rotating seat 3-302, and after being fixed by a locknut, the rotating seat 3-302 and the base 3-301 (arm portion 3-301b) are connected together. The rotating seat 3-302 can freely rotate up and down in the vertical direction (the third degree of freedom) around the fixed rotating shaft 3-304. Specifically, a gasket is provided on the outer side of the arm portion 3-301b to prevent excessive wear during rotation.

[0045] The opposite surfaces of the lamp holder connecting plate 3-303 and the rotating seat 3-302 are integrally provided with a protruding assembly column 3-305. A bearing snap ring 3-306 is sleeved outside the assembly column 3-305. The assembly column 3-305 and the bearing snap ring 3-306 are together inserted into the inner cavity of the clamping arm 3-302b, and then the bolts passing through the threaded holes on the clamping and fixing part 3-302c are tightened to clamp the two clamping arms 3-302b, connecting the lamp holder connecting plate 3-303 and the rotating seat 3-302 together.

[0046] Optionally, a circular groove b is provided on the surface of the assembly column 3-305, and through holes are machined on the clamping arm 3-302b (see Figure 11 and Figure 12 ). After the fixing pin is inserted through the through hole on the clamping arm 3-302b and then passes through the groove b on the assembly column 3-305, due to the limit cooperation between the fixing pin and the groove b, the fixing pin will not come out of the groove b, which can play an auxiliary fixing role to prevent the lamp holder connecting plate 3-303 from falling off after the bolts on the clamping and fixing part 3-302c become loose.

[0047] The lamp holder connecting plate 3-303 is connected to the lamp holder 2. Threaded holes are provided on the lamp holder connecting plate 3-303. The lamp holder 2 is installed on the lamp holder connecting plate 3-303 through the cooperation of screws and the threaded holes. A through hole along its own axis is machined on the assembly column 3-305, and a through hole passing through its center is also machined on the lamp holder connecting plate 3-303. The axes of the two through holes coincide. After the reinforcing bolt c passes through the through holes of the assembly column 3-305 and the lamp holder connecting plate 3-303 in sequence, it is threadedly engaged with the locknut. The lamp holder connecting plate 3-303 and the assembly column 3-305 can rotate around the axis of the assembly column 3-305 (the reinforcing bolt c), and then drive the lamp holder 2 connected to the lamp holder connecting plate 3-303 to rotate together (the fourth degree of freedom). The reinforcing bolt in this embodiment is a safety design, which can prevent the lamp holder connecting plate 3-303 and the assembly column 3-305 from breaking and the lamp holder connecting plate 3-303 from falling off under special circumstances such as external force impact, human damage, and falling, playing a role in ensuring the safety of the equipment.

[0048] As an optional implementation manner of the present utility model, both the lower arm 3-1 and the upper arm 3-2 are double-rod structures. The lower arm 3-1 includes a first rod 3-1a and a second rod 3-1b, and both the first rod 3-1a and the second rod 3-1b are sheet metal structures. The first rod 3-1a and the second rod 3-1b are respectively connected to the first arm socket part 3-5 and the first arm clamping part 3-7 through counter-locking screws. The first rod 3-1a, the second rod 3-1b, the first arm socket part 3-5 and the first arm clamping part 3-7 form an active hinge assembly similar to a parallelogram four-link mechanism. The first rod 3-1a and the second rod 3-1b can rotate around the counter-locking screws as the center to realize the rotation of the lower arm 3-1 in the vertical direction (the fifth degree of freedom).

[0049] The upper support arm 3-2 includes a third support rod 3-2a and a fourth support rod 3-2b, which are also sheet metal structures. The third support rod 3-2a and the fourth support rod 3-2b are connected to the second support arm sleeve portion 3-6 and the second support arm clamping portion 3-8 respectively through a locking screw, and the third support rod 3-2a, the fourth support rod 3-2b, the second support arm sleeve portion 3-6 and the second support arm clamping portion 3-8 constitute a movable hinge assembly similar to a parallel four-bar linkage. The third support rod 3-2a and the fourth support rod 3-2b can rotate around the locking screw to realize the rotation of the upper support arm 3-2 in the vertical direction (the sixth degree of freedom).

[0050] Further, optionally, the upper arm 3-1 and the lower arm 3-2 are both provided with a cover plate 3-10, which is fixed to the upper arm 3-1 and the lower arm 3-2 by screws, and can play a role in dust prevention and aesthetics. A cable collection hook can also be provided below the upper arm 3-1 and the lower arm 3-2 to centrally fix and store data cables, power cables, etc., and keep the cables neatly arranged.

[0051] The utility model provides a lamp holder clamping and rotating assembly, and a matching structure among the base, the rotating seat and the lamp holder connecting plate, so that the angle and position of the lamp holder can be adjusted in a small angle and a small range without adjusting the connecting arm, thereby making up for the deficiency that the connecting arm can only make large adjustments and is not flexible enough. Moreover, the closer the lamp holder is to the patient, the more it needs to be able to make fine adjustments in a small angle and a small range. The utility model can meet such application needs and has the characteristics of high degree of freedom and high flexibility.
