DETAILED DESCRIPTION

[0031] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-Figure 11 As shown, a pediatric oral examination device includes a lower arc plate 1 and an upper arc plate 2 rotatably disposed on the lower arc plate 1, and a support component for supporting the upper arc plate 2 is disposed between the upper arc plate 2 and the lower arc plate 1.

[0033] At the same time, a detachable mounting frame 3 is provided on the lower arc plate 1, and the angle between the mounting frame 3 and the end of the lower arc plate 1 is 40-50 degrees, and a detachable connecting frame 4 is provided on the mounting frame 3, and the connecting frame 4 includes a connecting part 41 and an inspection part 42, and the connecting part 41 is detachably arranged on the mounting frame 3, and the inspection part 42 is rotatably arranged on the connecting part 41.

[0034] Therefore, in actual use, the detachable setting allows for separate cleaning, so dry cleaning can be used for the connecting frame to avoid water ingress.

[0035] Secondly, the inspection part 42 is provided with an opening 421 for the doctor to observe the oral cavity, and a lamp bead 5 is arranged on the inner wall of the inspection part 42 above the opening 421, and a rotatable reflector 6 is arranged on the inner wall of the inspection part 42 on both sides and below the opening 421, and the inspection part 42 is provided with an adjusting piece corresponding to the reflector 6, and one end of the adjusting piece passes through the inspection part 42 and is located outside the inspection part 42 to facilitate the adjustment of the angle of the reflector 6.

[0036] Therefore, in actual use, the reflector 6 is arranged and the reflector 6 can rotate itself, so as to increase the irradiation range of the lamp bead 5. The lamp bead 5 is an integral body with its own power supply, and a button 51 is arranged at the end of the lamp bead 5 and passes through the inspection portion 42 to expose Furthermore, the structure of the reflector 6 includes a mounting member 64 , and a mirror body 65 is provided on the mounting member 64 , and the mounting member 64 is rotatably connected to the inspection portion 42 .

[0037] like Figure 2-Figure 8 As shown, the structure of the adjusting member is various, and it can be a connecting belt 62 or an adjusting column 63. When the adjusting member is a connecting belt 62, the specific structure is as follows: first, the reflector 6 is provided with a sphere 61 at one end close to the inspection portion 42, and a connecting column 422 is provided on the inner wall of the inspection portion 42, and a groove is provided in the connecting column 422 corresponding to the sphere 61. Therefore, in actual use, the sphere 61 and the groove are adapted to each other so that the reflector 6 can rotate.

[0038] At the same time, the adjusting member is two elastic connecting belts 62, and a plurality of positioning holes 621 are opened on the connecting belt 62, and a limiting column 423 is set on the outer wall of the inspection part 42, and one end of the connecting belt 62 is connected to the reflector 6, and the other end of the connecting belt 62 passes through the inspection part 42 and is exposed.

[0039] Therefore, in actual use, the rotation of the reflector 6 is limited by matching the positioning hole 621 with the limiting column 423, and the angle of the reflector 6 is adjusted by matching the positioning hole 621 at different positions with the limiting column 423.

[0040] When the adjusting member is an adjusting column 63, the specific structure is as follows: first, the adjusting member is a movable adjusting column 63, and a plurality of positioning holes 2 631 are provided on the adjusting column 63, and one end of the adjusting column 63 abuts against the reflector 6, and the other end of the adjusting column 63 passes through the inspection part 42 and is exposed. In addition, a spring 1 is provided between the reflector 6 and the inspection part 42, and the outer wall of the inspection part 42 is connected to the limiting column 2 424 through a rope.

[0041] Therefore, in actual use, the angle of the reflector 6 is adjusted by moving the adjustment column 63 and cooperating with the spring 1, and the rotation of the reflector 6 is limited by matching the positioning hole 631 with the limiting column 424.

[0042] like Fig. 9 As shown, the structure of the mounting frame 3 is as follows: first, the mounting frame 3 includes a base 31 and a moving plate 32 movably arranged on the base 31, and the moving plate 32 is provided with an elongated hole 321, and a fastener passes through the elongated hole 321 to be connected with the upper arc plate 2. The fastener is a screw.

[0043] Therefore, in actual use, by setting the movable plate 32, a fastener passes through the long hole 321 to connect with the upper arc plate 2, so that the movable plate 32 plays a supporting role on the upper arc plate 2. Moreover, the movable plate 32 is movable, so as to ensure that the movable plate 32 and the upper arc plate 2 are relatively close, thereby playing a better supporting role.

[0044] The moving structure of the moving plate 32 is as follows: first, a convex strip 311 is provided on the base 31, and the moving plate 32 is grooved corresponding to the convex strip 311, and the movement is achieved by the adaptation of the convex strip 311 and the groove. Moreover, the clamping part 314 and the boss 313 on the base 31 can limit the moving range of the moving plate 32.

[0045] Meanwhile, the structure between the mounting frame 3 and the lower arc plate 1 is various, and can be fixed or movable. However, when the connection between the mounting frame 3 and the lower arc plate 1 is fixed, the specific structure is as follows: a protrusion 11 is provided on the lower arc plate 1, and a connecting groove is provided on the base 31 corresponding to the protrusion 11.

[0046] When the connection between the mounting frame 3 and the lower arc plate 1 is movable, the specific structure is as follows: first, a movable protrusion 11 is provided on the lower arc plate 1, and a connecting groove is provided on the base 31 corresponding to the protrusion 11, and the protrusion 11 is connected to the adjusting plate 12, and the adjusting plate 12 passes through the lower arc plate 1 and is exposed, and the protrusion 11 is moved by moving the adjusting plate 12, thereby moving the base 31.

[0047] There is a mounting portion 13 between the protrusion 11 and the adjustment plate 12, and a groove 14 is provided on the lower arc plate 1 corresponding to the adjustment plate 12 and the mounting portion 13. Therefore, in actual use, the adjustment plate 12 and the mounting portion 13 move in the groove 14, thereby driving the protrusion 11 to move and then driving the base 31 to move.

[0048] like Figure 1-Figure 9 As shown, the structure between the mounting frame 3 and the connecting portion 41 is as follows: first, the mounting frame 3 includes a base 31 and a movable plate 32 arranged on the base 31, and the movable plate 32 is provided with a card slot 1 322, and the base 31 is provided with a card connection portion 314 on one side of the movable plate 32, and the card connection portion 314 is provided with a card slot 2 315.

[0049] Meanwhile, a hook 411 is provided at one end of the connection portion 41 , so that in actual use, the connection portion 41 is located in the first slot 322 and the second slot 315 , and the hook 411 can abut against the movable plate 32 to prevent the connection portion 41 from being separated from the mounting frame 3 .

[0050] Secondly, the limiting structure related to the inspection part 42 is as follows: first, a limiting block 412 is provided on the connection part 41, and a limiting groove 425 is provided on the inspection part 42 corresponding to the limiting block 412. Therefore, in actual use, the rotation of the inspection part 42 is limited by the matching of the limiting block 412 and the limiting groove 425.

[0051] At the same time, a second limiting groove 15 is provided on the upper surface of the lower arc plate 1, and a second rotatable limiting block 16 is provided on one side of the lower arc plate 1, and the inspection part 42 is located between the second limiting groove 15 and the second limiting block 16. Therefore, in actual use, the inspection part 42 is located between the second limiting groove 15 and the second limiting block 16 to limit the rotation of the inspection part 42.

[0052] The inspection portion 42 rotates by using conventional shaft-hole cooperation between the inspection portion 42 and the connecting portion 41 , and the second limit block 16 rotates by using conventional shaft-hole cooperation between the second limit block 16 and the lower arc-shaped plate 1 .

[0053] like Figure 1-Figure 9 As shown, the detailed structure of the inspection part 42 is as follows: first, both inner side walls of the opening 421 are inclined surfaces, and the distance between the two inner side walls increases as the direction approaches the child. Meanwhile, the lamp bead 5 is an LED dimming lamp with variable light intensity.

[0054] Among them, LED lamps are known for their low energy consumption and high brightness. Their brightness and energy consumption are more than 60% different from those of traditional tungsten filament bulbs. Therefore, they can be made dimmable, that is, LED dimming lamps. The brightness of the light can be adjusted according to customer requirements, thereby affecting the brightness of the indoor light and creating different indoor environment atmospheres.

[0055] Moreover, a detachable transparent membrane 43 is provided at the opening 421 corresponding to the inspection part 42, and the transparent membrane 43 is used to isolate children and doctors, and the structure of the transparent membrane 43 is: first, a movable moving frame 44 is provided at the bottom of the inspection part 42, and the moving frame 44 is provided with a transparent membrane 43 corresponding to the opening 421.

[0056] like Figure 10-11 As shown, the structure of the support assembly: first, the support assembly includes an adjustment assembly and a support rod 71, and the adjustment assembly includes a screw rod 1 72 and a screw rod 2 73 and a nut 74 for connecting the screw rod 1 72 and the screw rod 2 73, and the screw rod 1 72 and the screw rod 2 73 have the same spiral direction. At the same time, the top of the screw rod 1 72 is connected to the upper arc plate 2, and the bottom of the screw rod 2 73 is connected to the lower arc plate 1.

[0057] Therefore, in actual use, by rotating the nut 74, the screw rod 1 72 and the screw rod 2 73 are moved outward, thereby increasing the distance between the lower arc plate 1 and the upper arc plate 2 so as to adapt to the child's mouth, and by rotating the nut 74 in the opposite direction, it is locked to limit movement and play a supporting role.

[0058] The top of the screw rod 1 72 is an arc surface, and the upper arc plate 2 is correspondingly grooved, and the bottom of the screw rod 2 73 is plugged into the lower arc plate 1 .

[0059] Meanwhile, a mounting column 17 is arranged on the lower arc-shaped plate 1 , and the bottom of the support rod 71 is located inside the mounting column 17 , and a second spring is arranged between the support rod 71 and the mounting column 17 , and the top of the support rod 71 contacts the upper arc-shaped plate 2 .

[0060] Therefore, in actual use, when the upper arc plate 2 does not rotate, the gravity of the upper arc plate 2 squeezes the spring 2, and when the upper arc plate 2 rotates, the support rod 71 pushes the lower arc plate 1 under the action of the spring 2 and supports the lower arc plate 1.

[0061] The top of the support rod 71 is an arc surface, and the upper arc plate 2 is correspondingly grooved. The ends of the lower arc plate 1 and the upper arc plate 2 are connected by a rod 8, and the upper arc plate 2 and the rod 8 are rotatably connected. At the same time, the rotatable connection between the upper arc plate 2 and the rod 8 adopts a conventional shaft hole fit, and the rod 8 is provided so that a certain initial amount can be obtained, thereby reducing the amount of later adjustment.

[0062] The above shows and describes the basic principle and main features of the present invention and the advantages of the present invention. At the same time, the present invention is not limited by the above embodiments, so without departing from the principle and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
