The pupil distance is measured by aligning the light spot through a linear alignment structure, which solves the problems of difficulty in keeping the pupil still, infants and young children not cooperating, and poor measurement accuracy. The key points of its technical solution are: it includes a frame, a reference light source, and a distance adjustment mechanism for adjusting the distance between the reference light source and the frame, the reference light source adopts a point light source, and the reference light source can flash and / or emit light of different colors; the frame is provided with two viewports and a measuring mechanism for measuring the pupil distance, the measuring mechanism includes two alignment parts for aligning the measurement point in the pupil and a distance measuring part for measuring the distance between the two alignment parts; the distance adjustment mechanism includes a horizontally arranged slide bar and a slider that can slide on the slide bar, the slide bar is provided with a scale, and the reference light source and the slider move synchronously.

[0042] Embodiment 1:

[0043] Refer to the attached Figure 1-12 , a self-service pupil distance measuring device that is easy to operate, comprising a mounting seat 1, an adjusting component 2 is arranged on the mounting seat 1, and two adjusting ends of the adjusting component 2 are respectively provided with a bracket 3 and a measuring mechanism;

[0044] The measuring mechanism includes a pad 4, a sliding plate 5 is slidably connected to the top of the pad 4, a measuring component 6 is fixedly connected to one side of the top of the sliding plate 5, an identification component 7 with a recording function is arranged on the other side of the top of the sliding plate 5, a driving component 8 for lateral driving of the identification component 7 is arranged inside the sliding plate 5, a moving frame 9 is fixedly connected to the bottom of the pad 4, a rubber sleeve 10 is fixedly connected to the inside of the moving frame 9, and a guide rod 11 is slidably connected to the inside of the moving frame 9 through the rubber sleeve 10;

[0045] The bracket 3 and the measuring mechanism can be adjusted synchronously by adjusting the component 2 to meet the measurement needs of different groups of people;

[0046] By setting the measuring component 6 in the measuring mechanism, the eyeball of the eye can be positioned, and by setting the marking component 7, the pupil of the positioned eyeball can be positioned, thereby forming a self-service measurement work, and the measured result can be understood by the person being tested in real time, and the measuring component 6 can be marked on the marking component 7 to facilitate subsequent calculations, thereby improving the accuracy of the pupil distance measurement, and solving the problem that the pupil distance measurement device in the prior art is not convenient for positioning the eyeball when measuring the pupil distance, so that the pupil distance measurement cannot be quickly formed, and there is a lack of real-time marking;

[0047] The movable frame 9 is slidably connected to the outer surface of the guide rod 11 by a rubber sleeve 10 to ensure the stability of the movable frame 9 after being adjusted left and right. The sliding plate 5 is connected to the pad 4 in a sliding manner to facilitate the adjustment of the distance between the bracket 3 and the measuring mechanism according to different face shapes.

[0048] Refer to the attached Figure 7 The marking assembly 7 includes a movable frame 71 slidably connected to the top of the sliding plate 5, the top and one side of the movable frame 71 are both opened, a coordinate card 72 is inserted into the movable frame 71, a pressing plate 73 for pressing the coordinate card 72 is slidably connected to the inside of the movable frame 71, and a bolt rod 74 is threadedly connected to the other side of the movable frame 71, and one end of the bolt rod 74 is rotatably connected to the outer side of the pressing plate 73;

[0049] The coordinate card 72 adopts the card paper with scale coordinates printed on it in the prior art, which is not only convenient for the person being tested to look directly at the object during the measurement process to form the pupil distance detection work, but also convenient for the measurement component 6 to mark and form the record of the measurement data during the measurement. The coordinate card 72 is installed by plugging in, so that the user can replace the coordinate card 72. The pressing plate 73 can be driven to move left and right by rotating the bolt rod 74 by hand, and then the inserted coordinate card 72 can be fixedly installed to improve the stability of subsequent marking.

[0050] Refer to the attached Figure 8-Figure 12 The measuring assembly 6 includes a glasses frame 61 fixed to the top of the sliding plate 5, and two groups of shielding members 62 for shielding the eyes are arranged inside the glasses frame 61, and two positioning members 63 for positioning the eyes are arranged on the inner side surface of the glasses frame 61;

[0051] The two shielding members 62 are provided to shield the eyes so as to facilitate monocular detection. The positioning member 63 is provided to facilitate positioning of the pupil of the person being detected during direct vision, so as to facilitate subsequent measurement and identification of the pupil distance through the identification component 7.

[0052] Refer to the attached Fig.10 The inside of the glasses frame 61 is provided with two viewports 611, both sides of the top of the glasses frame 61 are provided with insertion slots 612 communicating with the inside of the viewports 611, and both sides of the glasses frame 61 are provided with movable openings 613;

[0053] The two viewports 611 are provided to facilitate the direct viewing of the identification assembly 7 by the eye, the insertion slot 612 is provided to facilitate the telescopic installation of the shielding member 62, and the movable opening 613 is provided to facilitate the adjustment of the positioning member 63 up, down, left, and right.

[0054] Refer to the attached Fig.11The shielding member 62 includes a baffle 621 inserted into the insertion slot 612, a metal plate 622 is fixedly connected to one side of the baffle 621, a side of the metal plate 622 passes through the eyeglass frame 61 and extends to the outside of the eyeglass frame 61, and a magnet block 623 for adsorbing the metal plate 622 is fixedly connected to one side of the top of the eyeglass frame 61;

[0055] The baffle 621 is arranged to be inserted into the insertion slot 612 to shield the glasses frame 61, thereby facilitating the measurement of one eye or both eyes. By driving the metal plate 622 up and down by hand, the baffle 621 can be adjusted up and down to form the regulation of the glasses frame 61. Moreover, the magnet block 623 adsorbs the metal plate 622 to ensure the stability of the baffle 621 after it is removed.

[0056] Refer to the attached Fig.12 The positioning member 63 includes a sliding block 631 slidably connected to the inside of the movable opening 613, an operating rod 632 is slidably connected to the inside of the sliding block 631, an elastic clamping sleeve 633 for elastically clamping the operating rod 632 is fixedly connected to the inside of the sliding block 631, a through pipe 634 is fixedly connected to one end of the operating rod 632, a wrapping cover 635 is fixedly connected to one end of the through pipe 634, the other end of the through pipe 634 is set to a constricted shape, and a painting pen 636 is fixedly connected to the outer surface of the other end of the through pipe 634 through a bracket;

[0057] The operating rod 632 is slidably connected to the inside of the sliding block 631, so that when the sliding block 631 slides up and down inside the movable opening 613, the operating rod 632 can be driven to move up and down. Through the up and down movement of the operating rod 632, the through pipe 634 can be adjusted up and down, left and right. The elastic clamping sleeve 633 is set to elastically clamp the operating rod 632 during telescopic adjustment to ensure the stability of the through pipe 634 adjustment; an elastic extrusion block is installed on the sliding block 631 to improve the stability of the sliding block 631 after sliding up and down;

[0058] By moving the through tube 634 to the position of the eyeball, the inner diameter of the through tube 634 is 2-10 mm, and the length is half of the distance between the eyeglass frame 61 and the identification component 7. When the person being tested observes the coordinate card 72 on the identification component 7 through the through tube 634, the direct vision positioning of the eyeball is formed. The setting of the wrapping cover 635 is used to protect the eye part, so that the person being tested can better see directly through the through tube 634 to prevent astigmatism. The other end of the through tube 634 is in a constricted shape, which is convenient for reducing the range when the other end of the through tube 634 contacts the coordinate card 72, thereby improving the pupil distance measurement effect;

[0059] When the inspected person observes the coordinate card 72 through the through tubes 634 in the two positioning members 63, the distance between the two through tubes 634 is the pupil distance of the inspected person. The driving component 8 drives one side of the marking component 7 to move, which not only makes the painting pens 636 in the two positioning members 63 come into contact with the coordinate card 72, thereby marking the coordinate card 72, but also facilitates one end of the through tube 634 to come into contact with the coordinate card 72, thereby reducing the spread of its line of sight. The inspected staff can automatically understand the value of their pupil distance through the through tube 634.

[0060] The working principle of the self-service pupil distance measuring device which is easy to operate in the present invention is as follows:

[0061] The person being tested places his chin on the top of the bracket 3 and is supported by the bracket 3. Finally, the height of the bracket 3 and the measuring mechanism is adjusted by the adjusting component 2 so that the eyes of the person being tested correspond to the eyeglass frame 61 in the measuring component 6.

[0062] During measurement, the person being tested controls the two positioning members 63 in the measuring assembly 6 with two hands, and manually drives the operating rod 632 up, down, left, and right, thereby driving the through tube 634 to adjust up, down, left, and right. Through the adjustment of the through tube 634 up, down, left, and right, the person being tested can match the wrapping cover 635 on the through tube 634 with the eyeball of the eye, and the pupil on the eyeball can be observed on the coordinate card 72 in the marking assembly 7 through the through tube 634, so as to form a direct vision operation, and finally realize the positioning of the two pupils;

[0063] By driving the identification component 7 laterally through the driving component 8, the identification component 7 can be driven to move along the position of the eyeglass frame 61. When the other ends of the two through tubes 634 come into contact with the coordinate card 72 in the identification component 7, the person being tested can directly look at the coordinate axes of the corresponding positions of the two through tubes 634 to know the pupil distance value. When the two through tubes 634 come into contact with the coordinate card 72, the drawing pens 636 on the two through tubes 634 can draw on the coordinate card 72, which is not only convenient for the subsequent calculation of the pupil distance and improves the measurement accuracy, but also convenient for the recording of the pupil distance value.

[0064] Embodiment 2: Based on embodiment 1, the difference is that;

[0065] Refer to the attached Figure 6 The driving assembly 8 includes a movable groove 81 opened inside the sliding plate 5, a driving plate 82 is slidably connected inside the movable groove 81, the top of the driving plate 82 is fixedly connected to the bottom of the movable frame 71, and an electric telescopic rod 83 is fixedly connected between one side of the driving plate 82 and the inner wall of the movable groove 81;

[0066] The electric telescopic rod 83 is connected to an external power supply and a control switch, and is used to drive the driving plate 82 to move left and right. The left and right movement of the driving plate 82 can drive the marking component 7 to move horizontally, so that the marking component 7 can contact the measuring component 6 to form a measurement and marking operation, thereby improving the convenience of pupil distance measurement.

[0067] Embodiment 3: Based on embodiment 1, the difference is that;

[0068] Refer to the attached Figure 4 and Figure 5 The adjustment assembly 2 includes two spur-tooth plates 21 slidably connected to the inside of the mounting seat 1, the bottom of the bracket 3 is fixed to the top of the left spur-tooth plate 21, the pad 4 and the guide rod 11 in the measuring mechanism are fixedly connected to the right spur-tooth plate 21, the bottom of the mounting seat 1 is rotatably connected to a gear 22 through a bracket, the gear 22 is meshed with the opposite side of the two spur-tooth plates 21, and the bottom of the mounting seat 1 is provided with a driving member for driving one of the spur-tooth plates 21 up and down;

[0069] By setting the driving member, one of the spur plates 21 can be driven to move up and down, and the up and down movement of the spur plate 21 can drive the bracket 3 to move up and down. Since the two spur plates 21 are meshed and transmitted through the gear 22, when one of the spur plates 21 moves up and down, the other spur plate 21 can be driven to move up and down, thereby forming a height adjustment of the measuring mechanism. The two spur plates 21 are adjusted in opposite or relative directions, thereby forming an adjustment work of the bracket 3 and the measuring mechanism, which has a synchronous dual adjustment function and meets the measurement work of different people.

[0070] The driving member includes a threaded rod 23 rotatably connected to the bottom of the mounting base 1, a threaded block 24 is threadedly connected to the outer surface of the threaded rod 23, and one side of the threaded block 24 is fixedly connected to one of the spur plates 21;

[0071] By rotating the threaded rod 23 by hand, the threaded block 24 can be driven to move up and down, and the up and down movement of the threaded block 24 can drive one of the spur plates 21 to move up and down, thereby forming the adjustment work of the adjustment assembly 2;

[0072] The driving member also includes a telescopic cylinder, which drives one of the spur plates 21 to move up and down, thereby performing the adjustment work of the adjustment component 2.

[0073] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0074] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
