[0031] The embodiments of the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0032] Please refer to Figures 1-3 , the present invention provides an eye socket depth and canthus width combination measuring device, which is characterized in that it includes a fixing plate, a placing component 2 and a measuring mechanism 3. It should be understood that when the present invention is used, the patient should preferably lie down and keep the face facing upwards.

[0033] There are multiple groups of placing components 2, and they are telescopically arranged on the fixing plate. The placing components 2 are preferably arranged at both ends of the fixing plate and face the patient's eyes. In this embodiment, there are two groups of placing components 2 respectively.

[0034] In other solutions, the placing component 2 includes a threaded rod 21 and a fixing block 22; the threaded rod 21 is screwed to the fixing plate and passes through the fixing plate to be rotatably connected to the fixing width. When in use, the fixing block 22 is abutted against the patient's face, and the threaded rod 21 is rotated to adjust the angular position of the fixing plate, etc., so that the measuring rod components 31 can respectively abut against the patient's upper eyelid and lower eyelid at the same horizontal height position.

[0035] The measuring mechanism 3 is provided with two groups and includes a measuring rod assembly 31, a depth adjustment assembly 32 and a width adjustment assembly 33 respectively; the measuring rod assembly 31 is slidably arranged on the bottom surface of the fixed plate and can slide downward spontaneously, and the two measuring rod assemblies 31 can abut against each other; a slide groove is provided on the fixed plate, and the width adjustment assembly 33 is slidably arranged in the slide groove and connected to the measuring assembly, and the width adjustment assembly 33 can limit the height position of the measuring rod assembly 31; a groove is provided on the fixed plate, and the depth adjustment assembly 32 is arranged on the groove of the fixed plate and connected to the measuring rod assembly 31, and the depth adjustment assembly 32 can drive the measuring rod assembly 31 and the width adjustment assembly 33 to slide in a direction perpendicular to the side surface of the fixed plate. It should be understood that the measuring rod assembly 31 can slide downward spontaneously means that the part of the measuring rod assembly 31 that is not connected to other parts can slide in a direction perpendicular to the bottom surface of the fixed plate, and will slide down to the lowest point due to its own gravity without other restrictions. It should be known that when the depth adjustment component 32 drives the measuring rod component 31 to slide, the width adjustment component 33 also slides therewith. In addition, the two measuring mechanisms 3 are arranged opposite to each other.

[0036] There are two groups of measuring mechanisms 3, which can correspond to the upper eyelid and the lower eyelid respectively. When in use, the device is first placed on the patient's face by placing the component 2, and then the two measuring mechanisms 3 are respectively abutted on the upper eyelid and the lower eyelid, and then the width adjustment component 33 is adjusted so that the measuring rod component 31 can spontaneously fall a certain distance without squeezing the eyes too much, and then the depth adjustment component 32 is adjusted so that the measuring rod component 31 placed on the upper eyelid or the lower eyelid slides up and down the eye respectively, and when the measuring rod component 31 is about to leave the eyelid, the width adjustment component 33 is readjusted so that the measuring rod component 31 always abuts against the patient's eyelid during the upward or downward sliding process, that is, when the two measuring rod components 31 stretch the upper eyelid and the lower eyelid to the maximum position, the distance that the two measuring rod components 31 slide to the upper and lower sides of the eye is the width of the eye corner, and the distance that the measuring rod component 31 slides down under its own gravity is the depth of the eye socket.

[0037] In other solutions, the measuring rod assembly 31 includes a measuring rod 311, a connecting rod 312, and a rack 313; the connecting rod 312 is slidably connected to the bottom surface of the fixing plate, a groove is provided on the connecting rod 312, the rack 313 is fixed in the groove of the connecting rod 312, the rack 313 is connected to the width adjustment assembly 33, and the width adjustment assembly 33 can drive the rack 313 to slide; the measuring rod 311 is slidably connected to one end of the connecting rod 312 away from the width adjustment assembly 33 and can slide in a direction perpendicular to the bottom surface of the fixing plate, the top end of the measuring rod 311 is connected to the depth adjustment assembly 32, and the depth adjustment assembly 32 can limit the sliding distance of the measuring rod 311. The rack 313 drives the connecting rod 312 to slide, and the connecting rod 312 drives the measuring rod 311 to slide. It should be understood that the connecting rod 312 is concave-shaped, both sides of its top surface are slidably connected to the fixing plate, and the top surface of the measuring rod 311 abuts against the bottom surface of the fixing plate. In addition, the fixing plate is a cube, and the sliding direction of the rack 313 is perpendicular to the side surface of the fixing plate.

[0038] In other solutions, the depth adjustment assembly 32 includes a slider 321, a telescopic rod 322, a sliding rotating shaft 323, a connecting rope 324, and a first adjusting member 325; the slider 321 is slidably connected in the chute, and its sliding direction is the same as that of the rack 313, and the slider 321 is connected to the measuring rod 311 through the telescopic rod 322; the sliding rotating shaft 323 is rotatably connected to the slider 321 and is connected to the measuring rod 311 through the connecting rope 324; the first adjusting member 325 is provided on the slider 321 and can drive the sliding rotating shaft 323 to rotate unidirectionally. It should be understood that there are two sliders 321, which are respectively slidably connected in the chute relatively and are connected through the sliding rotating shaft 323. The setting of the telescopic rod 322 prevents the measuring rod 311 from being driven by the rack 313 to slide. When the measuring rod 311 slides, the measuring rod 311 can drive the slider 321, the sliding rotating shaft 323, the connecting rope 324, and the first adjusting member 325 to slide together through the telescopic rod 322. During use, adjust the winding condition of the connecting rope 324 on the sliding rotating shaft 323 as needed to make the measuring rod 311 slide down to a certain position. It should be understood that the connecting rope 324 has very little elasticity, and it is difficult to stretch it by an external force. By adjusting the winding condition of the connecting rope 324 on the sliding rotating shaft 323, the maximum sliding distance that the measuring rod 311 can slide down can be changed. At the same time, in the initial state, the top surface of the measuring rod 311 abuts against the bottom surface of the fixing plate and cannot rise further. At this time, the connecting rope 324 is wound around the sliding rotating shaft 323, and rotating the sliding rotating shaft 323 through the first adjusting member 325 can gradually release the wound connecting rope 324.

[0039] In other solutions, the first adjusting member 325 includes a first worm gear 3251, a first worm 3252, a connecting frame 3253, and a first turntable 3254; one end of the connecting frame 3253 is fixedly provided on the slider 321, and the other end is rotatably connected to the first worm 3252. The first worm gear 3251 is coaxially fixedly provided on the sliding rotating shaft 323, and the first worm gear 3251 meshes with the first worm 3252; the first turntable 3254 is coaxially fixedly provided on the first worm 3252. By setting the worm and worm gear mechanism, it is difficult for the measuring rod 311 to drive the connecting rope 324 to drop.

[0040] In other solutions, the depth adjusting assembly 32 includes a gear 331, a rotating rod 332, and a second adjusting member 333; a groove is provided at one end of the fixing plate close to the chute, the rotating rod 332 is rotatably provided in the groove of the fixing plate, the gear 331 is coaxially fixedly provided on the rotating rod 332, and meshes with the rack 313; the second adjusting member 333 is rotatably provided in the groove of the fixing plate and can drive the gear 331 to rotate unidirectionally.

[0041] In other solutions, the second adjusting member 333 includes a second worm gear 3331, a second worm 3332, and a second turntable 3333; the second worm gear 3331 is coaxially fixedly provided on the rotating rod 332, the second worm 3332 is rotatably provided in the groove of the fixing plate and meshes with the second worm gear 3331; a communication hole is further provided in the groove of the fixing plate, and the second turntable 3333 passes through the communication hole and is coaxially fixedly provided on the second worm 3332. It should be understood that the communication hole communicates the groove of the fixing plate with the top surface of the fixing plate, one side of the second turntable 3333 passes through the communication hole, and the other side is located on the groove of the fixing plate.

[0042] In other solutions, a spring 4 is further provided. One end of the spring 4 is provided on the measuring rod 311, and the other end is provided on the slider 321. By providing the spring 4, a force that always pushes against the bottom surface of the lower fixing plate can be applied to the measuring rod 311, so that the problem that the measuring rod 311 is difficult to drive the eyelid to slide is reduced during operation.

[0043] In other solutions, a scale 5 is further provided on the side surfaces of the fixing plate and the measuring rod 311.

[0044] It should also be understood that the device shown in the present application can be repeatedly used through means such as disinfection. In addition, the thickness of the measuring rod 311 can be made as thin as possible to avoid measurement errors caused by an overly thick measuring rod 311.

[0045] It is worth mentioning that a convex platform is provided on the bottom surface of the fixing plate 1 near the two measuring rods 311, and the eye socket depth is obtained by comparing the change of the scale on the measuring rod 311 on the convex platform.

[0046] The above-mentioned device for measuring the width of the eye corners can measure the depth of the eye socket and the width of the eye corners by sliding the upper and lower eyelids to the maximum position, avoiding the need to use multiple instruments or disposable expensive instruments during measurement.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
