[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-7 , the present utility model provides a technical solution:

[0030] A portable ophthalmic vision examination device, including a storage cylinder 1, a winding rod 3 is movably installed in the storage cylinder 1, an E chart 5 is arranged on the winding rod 3, a counterweight plate 18 is fixedly installed at the lower end of the E chart 5, movable blocks 19 are movably installed on both sides of the counterweight plate 18, and first magnets 7 are arranged on the movable blocks 19;

[0031] Both ends of the storage cylinder 1 are fixedly connected with mounting seats 2, the winding rod 3 is rotatably installed in the mounting seats 2, and a third magnet 17 is arranged at the bottom of the mounting seats 2.

[0032] In an optional embodiment: an adjusting rod 8 is movably installed in the mounting seat 2, a moving block 9 is threadedly installed on the adjusting rod 8, a fixing block 12 is fixedly connected to the bottom of the moving block 9, a moving groove 11 is formed in the mounting seat 2, the fixing block 12 is arranged in the moving groove 11, and a second magnet 13 is fixedly installed on the side of the fixing block 12.

[0033] It should be noted that when the device needs to be installed, through the cooperation of the adjusting rod 8, the moving block 9 and the fixing block 12, the second magnet 13 can be moved out of the mounting seat 2, and the device can be adsorbed and fixed on a magnetic material through the second magnet 13, such as behind an iron door or on the surface of a device with metal, so as to facilitate the installation of the device.

[0034] In an optional embodiment: a positioning groove 10 is formed at the top of the mounting seat 2, and the moving block 9 is slidably installed in the positioning groove 10.

[0035] It should be noted that by sliding the moving block 9 in the positioning groove 10, the fixing block 12 can be positioned, so as to facilitate the installation of the device.

[0036] In an optional embodiment: a hanging block 14 is fixedly connected to the top of the moving block 9, and a through hole 15 is formed in the hanging block 14.

[0037] It should be noted that when there is no magnetic material in the installation scenario, such as a wall surface, after fixing the fixing part to the wall surface, through the cooperation of the hanging block 14 and the through hole 15, the device can be hung and installed.

[0038] In an optional embodiment: a soft magnetic strip 6 is wound on the winding rod 3, and the E chart 5 is arranged on the soft magnetic strip 6.

[0039] It should be noted that through the arrangement of the soft magnetic strip 6, when the device is installed on a magnetic material, the soft magnetic strip 6 can be adsorbed on the magnetic material, thereby improving the stability of the installation of the E chart 5 and preventing the E chart 5 from shaking and affecting the use.

[0040] In an optional embodiment: a storage opening 4 is formed in the storage cylinder 1, and both the E chart 5 and the soft magnetic strip 6 are arranged in the storage opening 4.

[0041] In an alternative embodiment: A double-sided adhesive 21 is pasted on the end of the movable block 19, and a release paper 22 is provided on the side of the double-sided adhesive 21.

[0042] It should be noted that when the device is fixed on a non-magnetic material, such as a wall surface, after uncovering the release paper 22, the movable block can be adsorbed and fixed on the object to which the device is to be fixed, so that the E chart 5 can be kept in a relatively vertical state, and the shaking of the E chart 5 can be prevented from affecting the use.

[0043] In an alternative embodiment: Handles 16 are fixedly installed at both ends of the winding rod 3.

[0044] In an alternative embodiment: The bottom of the mounting seat 2 is fixedly connected to a fixed seat 23, the bottom of the fixed seat 23 is damping-hinged to a first mounting bracket 24, the bottom of the first mounting bracket 24 is damping-hinged to a second mounting bracket 25, LED lights 26 are provided on the inner sides of the first mounting bracket 24 and the second mounting bracket 25, and a storage battery 27 for powering the LED lights 26 is provided in the movable slot 11.

[0045] It should be noted that the E chart 5 can be illuminated by the LED lights 26. Sufficient light can avoid inaccurate test results caused by insufficient light, ensuring that doctors can accurately evaluate the vision conditions of patients. Through the damping settings of the fixed seat 23, the first mounting bracket 24 and the second mounting bracket 25, the first mounting bracket 24 and the second mounting bracket 25 can be folded and stored, facilitating the carrying of the device;

[0046] During specific use, when the device needs to be used in a different location, by rotating the winding rod 3 through the handle, when the winding rod 3 rotates, the soft magnetic strip 6 and the E chart 5 can be wound up. The E chart 5 can be wound into the storage cylinder 1, reducing the volume of the device, thus facilitating the carrying of the device. At the same time, the storage cylinder 1 can protect the E chart 5, preventing the E chart 5 from being scratched by foreign objects and improving the safety of the E chart 5;

[0047] When the soft magnetic strip 6 and the E chart 5 are wound into the storage cylinder 1, the first magnet 7 is adsorbed on the third magnet 17, so that the weight plate 18 can be adsorbed and fixed on the bottom of the mounting seat 2. The storage opening 4 can be blocked by the weight plate 18, preventing foreign objects from entering the storage cylinder 1 and soiling the E chart 5. The sealing effect of the storage opening 4 can be improved through the rubber pad 20. While the weight plate 18 is adsorbed on the bottom of the mounting seat 2, it prevents the E chart 5 from being pulled out of the storage cylinder 1, facilitating the carrying of the device.

[0048] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
