Abstract
The utility model relates to a vision improves training technical field, discloses a interpupillary distance adjusting device, including lens cone, threaded rod, screwed pipe, interpupillary distance regulating wheel, pinion, lens barrel holder, gear fixing base, gear stationary blade. The pupil distance adjusting wheel is pushed to change forwards and backwards to drive the threaded rod to rotate, so that the lens barrel can move inwards or outwards stably at the same time, and the pupil distance can be adjusted according to the pupil distance between the eyes of a user to adapt to users with different pupil distances.
Description
Technical Field
The utility model relates to a vision improves training technical field, specifically is a interpupillary distance adjusting device.
Background
Common visual training instruments in the market can rarely carry out targeted setting on the design of interpupillary distance adjustment. Because the pupil distance of each person is different, if the same setting is used without distinction, the focuses of the two eyes of the user cannot be focused accurately at the same time, so that the experience effect is poor, the training result is limited, and the expected training effect cannot be achieved finally.
Disclosure of Invention
The utility model aims at providing a but interpupillary distance adjusting device of interpupillary distance between adaptation user's both eyes is adjusted to interpupillary distance to solve the technical problem who exists among the above-mentioned background art.
The utility model discloses the technical scheme who adopts does: comprises a lens cone, a threaded rod, a threaded pipe, a pupil distance adjusting wheel, a pinion, a lens cone frame, a gear fixing seat and a gear fixing sheet.
The pupil distance adjusting device comprises two symmetrical lens cones, the lens cones are in a long hollow cylindrical shape, and threaded pipes for screwing in threaded rods are transversely fixed at the bottoms of the lens cones.
The pupil distance adjusting device and the gear fixing seat are positioned at the bottom of the lens barrel frame and form a fixing device with the gear fixing plate, and the fixing device is used for fixing the pinion and the pupil distance adjusting wheel on the threaded rod.
Pupil distance adjusting device, threaded rod middle part have a pinion, and both sides are the rotatory screw thread of symmetry, rotate into the threaded rod with the screwed pipe of two lens cone bottoms respectively according to the direction of screw thread, fix on the gear fixing base with the gear fixing piece behind the pupil distance regulating wheel meshing pinion, promote pupil distance regulating wheel and can drive pinion rotation, then the pinion can drive the threaded rod and rotate, the screwed pipe of screw in threaded rod can drive the lens cone inwards simultaneously or outside steadily to remove according to the direction of promotion of pupil distance regulating wheel.
The pupil distance adjusting device adopts the technical scheme that the threaded rod and the threaded pipe are used as the setting of meshing, so that the pupil distance adjusting device is good in stability, cannot be separated out of the movement range of the threaded rod, and effectively increases the stability of the threaded rod in the movement process of driving the lens cone to simultaneously move outwards or inwards.
The utility model has the advantages that: the pupil distance adjusting wheel is pushed by a hand to change forwards and backwards, the associated pinion and the associated threaded rod are driven to rotate, the lens barrel can be stably moved inwards or outwards to adjust the pupil distance finally according to the pupil distance between the eyes of a user, the pupil distance adjusting range is 55-70 mm, double-eye image combination is effectively promoted, comfortable use experience is brought to the user, and the whole use effect is improved.
Drawings
Fig. 1 is a top view of a preferred embodiment of the present invention.
Fig. 2 is a side view of the preferred embodiment of the present invention.
Fig. 3 is a front view of the preferred embodiment of the present invention.
In the figure: 1. a lens barrel; 2. a threaded rod; 3. a threaded pipe; 4 pupil distance adjusting wheels; 5. a pinion gear; 6. a lens barrel holder; 7. a gear fixing seat; 8. the gear fixing piece.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
It should be noted that, in the description, the terms "upper", "lower", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positions shown in the drawings, and are used for convenience of description only and not for specifying the orientations or positions that components must have.
As shown in fig. 1 to 3, the utility model provides a interpupillary distance adjusting device, including lens cone 1, transversely fix the screwed pipe 3 in lens cone 1 bottom, fix pinion 5 at 2 middle parts of threaded rod, with the interpupillary distance regulating wheel 4 of pinion 5 meshing, gear fixing base 7 is fixed in lens cone frame 6 bottom, and pinion 5 and interpupillary distance regulating wheel 4 are fixed on gear fixing base 7 by gear fixing piece 8.
Pupil distance adjusting device's lens-barrel 1 is microscler cavity cylindricly, and two for the symmetry, transversely be fixed with the screwed pipe 3 that supplies 2 screw ins in lens-barrel 1 bottom, can drive pinion 5 in the threaded rod 2 and rotate when promoting pupil distance regulating wheel 4 and carry out the seesaw, pinion 5 can drive threaded rod 2 and rotate, and screwed pipe 3 of screw in threaded rod 2 can drive lens-barrel 1 inwards or outwards remove in order to reach the purpose of adjusting the pupil distance simultaneously according to the direction of promotion of pupil distance regulating wheel 4, the utility model discloses a pupil distance adjusting device is applied to in wear-type vision improvement, visual health care or the visual training equipment.
The pupil distance adjusting device is good in stability and cannot be separated from the movement range of the threaded rod 2 due to the fact that the threaded rod 2 and the threaded pipe 3 are used for setting engagement.
The pupil distance adjusting device can realize the simultaneous inward or outward stable movement of the two lens barrels 1 only by pushing the pupil distance adjusting wheel 4, greatly simplifies the operation process, saves time and labor, has the pupil distance adjusting range of 55-70 mm, makes the binocular fusion easier, and improves the experience comfort of different users.
The above description is only for the preferred embodiment of the present invention, and not for limiting the scope of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; any modification or replacement within the spirit and principle of the present invention will not cause the essence of the corresponding technical solution to depart from the scope of the technical solution of the embodiments of the present invention, which should be included in the protection scope of the present invention.
