[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] like Figures 1 to 8 As shown, the forehead mirror for otolaryngology provided by the utility model includes a wearing piece 1, a universal connecting frame installed on the wearing piece 1 and a reflector 2 suspended at the bottom of the universal connecting frame, and an observation hole is arranged at the center of the reflector 2, wherein a hard connecting piece 3 is arranged on the surface of the wearing piece 1, and a sliding connecting piece 4 is arranged on the top of the universal connecting frame, the sliding connecting piece 4 and the hard connecting piece 3 are slidably matched in the length direction of the wearing piece 1, and a positioning piece for fixing the sliding connecting piece 4 at different positions on the hard connecting piece 3 is arranged on the sliding connecting piece 4.
[0027] After the sliding connector 4 and the hard connector 3 are set, the hard connector 3 has a stable guiding effect on the sliding connector 4, so that the sliding connector 4 can slide left and right to achieve the effect of adjusting the left and right position of the reflector 2. After the left and right position of the reflector 2 is adjusted, the positioning piece can be used to fix it in the adjusted position.
[0028] By making the above arrangement, when medical staff use the ENT mirror, the reflector 2 can be displaced left and right relative to the wearing member 1, and the position of the reflector 2 can be adjusted according to the direction of the field of vision without loosening the wearing member 1 after the wearing member 1 is worn on the head. This arrangement does not require the wearing member 1 to be displaced on the head and the wearing member 1 to be frequently loosened and then put back on when adjusting the position of the reflector 2 left and right as in the prior art. Therefore, it is more convenient to use.
[0029] The rigid connector 3 is arc-shaped, and an arc-shaped mounting groove 5 is arranged inside it. The sliding connector 4 is a "convex"-shaped slider, and its wider end is slidably arranged in the mounting groove 5, and its narrower end extends out of the mounting groove 5 and is connected to the universal connecting frame. Specifically, the rigid connector 3 can be made by bending a metal sheet, or can be made by processing a plastic part, which will not be described in detail here.
[0030] The universal connecting frame includes two clamping plates 6 arranged opposite to each other, spherical grooves 7 are arranged at the bottoms of the opposite sides of the two clamping plates 6, a connecting ball 8 is sleeved between the two spherical grooves 7, and the reflector 2 is fixedly connected to the connecting ball 8 through a lower connecting rod, one of the clamping plates 6 is rotatably connected to a rotating screw 9, and the other clamping plate 6 is threadedly sleeved on the rotating screw 9, circular grooves 10 are opened on the tops of the opposite sides of the two clamping plates 6, and a columnar body 22 is sleeved between the two circular grooves 10, an upper connecting rod 11 is fixedly arranged on the columnar body 22, and the top end of the upper connecting rod 11 is fixedly connected to the sliding connecting piece 4.
[0031] Specifically, by rotating the screw 9 in the forward or reverse direction, the two clamping plates 6 can be moved closer or farther away from each other. When the two clamping plates 6 are moved closer to each other, the connection ball 8 is clamped and fixed from both sides, which has the function of fixing the reflector 2. In addition, when the two clamping plates 6 are moved away from each other, the clamping force on the connection ball 8 is removed, which has the function of facilitating the adjustment of the reflector 2.
[0032] Among them, in this embodiment, the upper connecting rod 11 is set as a plate-like structure. When the two clamping plates 6 clamp the connecting ball 8, the two clamping plates 6 clamp the upper connecting rod 11 from both sides of the upper connecting rod 11, so that the upper connecting rod 11 and the clamping plates 6 are in a relatively fixed state. When the two clamping plates 6 release the connecting ball 8, the two clamping plates 6 also release the upper connecting rod 11. At this time, the distance between the bottom end of the clamping block and the face of the person can be adjusted by rotating the clamping block up and down with the columnar body 22 as the center, so as to achieve the effect of adjusting the distance between the reflector 2 and the face of the person in the front and rear directions.
[0033] Furthermore, both ends of the cylindrical body 22 are provided with a "T"-shaped limit shaft 12, the limit shaft 12 passes through the splint 6, and the larger end of the limit shaft 12 is located on the outside of the splint 6, wherein a gap is provided between the larger end of the limit shaft 12 and the splint 6, and the length of the gap along the axial direction of the cylindrical body 22 is less than half the depth of the circular groove 10 on the cylindrical body 22.
[0034] By such arrangement, when the two clamping plates 6 loosen the upper connecting rod 11 and the connecting ball 8, the larger end of the limiting shaft 12 has a limiting effect on the displacement distance of the clamping block, which can prevent the cylindrical body 22 from being separated from the circular groove 10, and at the same time, prevent the connecting ball 8 from being separated from the spherical groove 7. At the same time, the rotating screw 9 and the cylindrical body 22 respectively limit the middle and top parts of the two clamping blocks in the circumferential direction, which can prevent the clamping blocks from rotating when the rotating screw 9 is turned.
[0035] The positioning member includes a locking portion 13, a connecting portion 14 and a driving portion 15. The locking portion 13 is arranged in the sliding connecting member 4, and the locking portion 13 can be displaced radially inward along the hard connecting member 3 on the sliding connecting member 4 to abut against the inner wall of the mounting groove 5. The driving portion 15 is arranged on the universal connecting frame, and the connecting portion 14 is arranged between the locking portion 13 and the driving portion 15.
[0036] Specifically, the locking part 13 has a "π"-shaped structure, with its larger end in an arc-shaped plate that matches the mounting groove 5, and its smaller end is slidably mounted on the sliding connector 4. The connecting part 14 is parallel to the upper connecting rod 11, and the connecting part 14 is located on the side of the upper connecting rod 11. The top of the connecting part 14 is inserted into the sliding connector 4, and the top of the connecting part 14 and the smaller end of the locking part 13 are matching inclined surfaces. The driving part 15 is arranged on the conical surface at the top of the clamp 6, and the bottom end of the connecting part 14 is arranged to be a conical surface that matches the top of the clamp block, wherein when the two clamp blocks move relative to each other, their top ends push up the connecting part 14, and the top of the connecting part 14 presses the locking part 13 inward.
[0037] By making the above arrangement, when the rotating screw 9 is rotated to loosen the two clamping plates 6, the two clamping plates 6 remove the force on the connecting portion 14, and at this time, the connecting portion 14 removes the squeezing effect on the locking portion 13, and then, when the rotating screw 9 is rotated to make the clamping plates 6 loosen the connecting ball 8 and the upper connecting plate, the squeezing force between the locking portion 13 and the inner side wall of the mounting groove 5 also disappears synchronously, so that the direction, pitch angle and distance between the reflector 2 and the human eye can be adjusted, and the reflector 2 can be displaced in the left and right directions. When the reflector 2 is adjusted, it is only necessary to rotate the rotating screw 9 again, and when the two clamping blocks clamp the upper connecting rod 11 and the connecting ball 8, the connecting portion 14 squeezes the locking portion 13 so that the locking portion 13 is pressed against the groove wall of the mounting groove 5, thereby synchronously realizing the function of positioning the reflector 2 in the left and right directions.
[0038] Furthermore, the center of the driving portion 15 coincides with the center of the cylindrical body 22. At this time, when the angle between the clamping plate 6 and the upper connecting rod 11 changes to adjust the distance between the reflector 2 and the human eye, after the two clamping plates 6 move relative to each other, the driving portion 15 still has the effect of squeezing the connecting portion 14. A sliding groove 16 is provided on the surface of the upper connecting rod 11, and a sliding block 17 is provided on one side of the connecting portion 14 facing the upper connecting rod 11, and the sliding block 17 is slidably arranged in the sliding groove 16. In this arrangement, the sliding groove 16 cooperates with the sliding block 17 to prevent the upper connecting rod 11 from being separated from the connecting portion 14 in the length direction of the upper connecting rod 11, and the top end of the connecting portion 14 is inserted into the sliding connector 4 to achieve stable installation of the connecting portion 14.
[0039] A limiting ring 18 is protruded from the surface of the rotating screw 9, and an annular limiting groove 19 is provided in the clamping plate 6 that rotates with the rotating screw 9, and the limiting ring 18 is located in the annular limiting groove 19. In this way, the annular limiting groove 19 cooperates with the limiting ring 18, so that the rotating screw 9 is effectively connected to one of the clamping plates 6.
[0040] An external pull spring 20 is provided between the two smaller ends of the locking portion 13, and a receiving groove is provided on the sliding connection member 4, and the outer end of the receiving groove is fixedly connected to the inner wall surface of the outer end of the receiving groove. By providing the external pull spring 20, when the connecting portion 14 removes the squeezing effect on the locking portion 13, the external pull spring 20 will pull the locking portion 13 outward to separate the locking portion 13 from the side wall of the installation groove 5.
[0041] A flexible pad 21 is provided on one side of the wearable component 1 opposite to the hard connector 3, covering the hard connector 3 in the length direction. Specifically, the flexible pad 21 can be sponge or silicone, which can adapt to the foreheads of different medical personnel by its own flexibility, and at the same time, reduce the discomfort caused by the hard connector 3 to the forehead of the medical personnel.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
