Description

Technical Field

[0001] The utility model relates to the technical field of surgical magnifiers, in particular to an inlaid binocular surgical magnifier which is easy to adjust. Background Art

[0002] Most existing surgical magnifying glasses use external fixing parts to connect the lens barrel and the lens frame together. First, the structure is complex, and second, the weight is relatively heavy, which can easily cause fatigue during the operation. Moreover, the lens barrels generally used are circular, which block the observation field of view to a large extent, affecting normal communication. In view of this situation, the applicant proposed a mosaic binocular surgical magnifying glass in the Chinese utility model patent with announcement number CN213302706U. The magnifying lens barrel uses a circular split lens barrel directly inlaid on the lens, which reduces the problem of increased counterweight caused by the use of other external connecting parts, expands the width of the field of view, and does not affect the user's raising of the eyes to communicate with external personnel.

[0003] However, the two magnifying lens tubes of this structure are not adjustable, and the distance and angle cannot be adjusted according to the user's pupil distance, which limits its use and makes it unable to adapt to the needs of different users. Utility Model Content

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0026] A conveniently adjustable inlaid binocular surgical magnifier, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a frame 1, with temples 2 hinged at both ends of the frame 1, a nose pad 3 installed in the middle of the frame 1, two lenses 4 symmetrically arranged at the bottom of the frame 1, a magnifying lens barrel 5 inlaid on the lens 4, a lens frame 6 is arranged around the lens 4, and a first adjusting screw 7 and a second adjusting screw 8 with the same diameter are welded on the top of the lens frame 6, a first oblong hole 9 corresponding to the first adjusting screw 7 is symmetrically opened on the frame 1, and a second oblong hole 10 corresponding to the second adjusting screw 8 is symmetrically opened on the frame 1, the width of the first oblong hole 9 is the same as the diameter of the first adjusting screw 7, and the width of the second oblong hole 10 is larger than the width of the first oblong hole 9, the upper end of the first adjusting screw 7 passes through the corresponding first oblong hole 9 and is locked by a first nut 11, the upper end of the second adjusting screw 8 passes through the corresponding second oblong hole 10 and is locked by a second nut 12, and a sleeve 13 is sleeved on the top of the lens frame 6 outside the first adjusting screw 7 and the second adjusting screw 8, and the top of the sleeve 13 abuts against the bottom of the frame 1.

[0027] The mirror frame 1 is an n-shaped structure.

[0028] The temples 2 are hinged to the vertical frames on both sides of the frame 1, and the ear-hanging ends of the temples 2 are provided with protective covers 14.

[0029] The lens frame 6 is an L-shaped structure, covering the top of the lens 4 and the upper end of the inner side.

[0030] When the utility model is used, the distance between the two lenses 4 can be adjusted according to the needs of the wearer to adapt to different pupil distance requirements. The angle of the lens 4 can also be adjusted, so that the two magnifying lens barrels 5 can be better focused to ensure the observation effect. The specific operation is to loosen the first nut 11 and the second nut 12, slide the first adjusting screw 7 and the second adjusting screw 8, so as to adjust the left and right position of the first adjusting screw 7 in the first oblong hole 9 and the left and right position of the second adjusting screw 8 in the second oblong hole 10, so as to change the distance between the two lenses 4. By changing the front and rear position of the second adjusting screw 8 in the second oblong hole 10, the angle of the lens 4 can be adjusted. After the adjustment is completed, tighten the first nut 11 and the second nut 12 to achieve the adjustment of the position and angle of the lens 4 and the two magnifying lens barrels 5.

[0031] The arrangement of the two sets of screws makes the fixation of the lens frame 6 more stable.

[0032] The form of the magnifying lens barrel 5 is not fixed.

[0033] For example, the magnifying lens barrel 5 includes a circular lens barrel 511 embedded on the lens 4 and a square lens barrel 512 formed integrally with the circular lens barrel 511. Figure 4 As shown, an eyepiece is installed in the circular mirror tube 511, and an objective lens is installed in the square mirror tube 512.

[0034] The depression angle between the magnifying lens barrel 5 and the lens 4 is 40-55°, preferably 55°. At this time, when the magnifying lens barrel 5 is inlaid, the processing angle and shape of the mounting hole on the lens 4 need to be more accurately controlled, and the processing requirements are higher.

[0035] There is a depression angle between the magnifying lens barrel 5 and the lens 4, so that the user can observe with his eyes without lowering his head during the operation, thereby avoiding damage to the cervical spine caused by the user lowering his head for a long time.

[0036] For another example, the magnifying lens barrel 5 includes an eyepiece barrel 521, a rotating lens barrel 522 and an objective lens barrel 523 which are integrally formed. Figure 5 As shown, the eyepiece barrel 521 is inlaid on the lens 4, an eyepiece is installed in the eyepiece barrel 521, a corner prism is installed in the corner barrel 522, and an objective lens is installed in the objective barrel 523.

[0037] Observe the object through the eyepiece, use the angle optical refraction principle to change the observation direction, and then form an image through the objective lens. The setting of the angle lens barrel 522 can eliminate the need to place higher requirements on the mounting holes on the lens 4 when inlaying the magnifying lens barrel 5.

[0038] The steps of installing the lens 4 of the utility model are as follows Figure 6 , Figure 7 , Figure 8 As shown, specifically:

[0039] A first adjusting screw 7 and a second adjusting screw 8 are welded on the top of the lens frame 6 , a sleeve 14 is mounted on the first adjusting screw 7 and the second adjusting screw 8 , the first adjusting screw 7 and the second adjusting screw 8 are inserted into the frame 1 and are locked by means of a first nut 11 and a second nut 12 .

[0040] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
