Description

Technical Field

[0001] The utility model relates to the technical field of light-shielding brackets, in particular to a light-shielding supporting slide seat of a universal eye examination machine. Background Art

[0002] An eye exam machine is a device used to monitor eye health. It uses various optical, electronic, and computer-based techniques to perform a comprehensive examination and assessment of the eyes. Common eye exam machines include ophthalmometers.

[0003] In the existing patent literature, there is a patent with publication number CN117958741A, named "Computer Refractor". The support frame in the patent only has a supporting function. However, in actual application, in order to promote eye health examinations or conduct free eye examinations, the refractor is usually carried outdoors for use. Because the outdoor light is too strong and the support frame cannot block light, it will affect the outdoor refractor's eye test results, making it very inconvenient to use. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a light-shielding supporting slide for a universal eye examination machine. When the eye examination machine is used outdoors, the two semi-light-shielding covers can be rotated toward the middle respectively. At this time, the two semi-light-shielding covers can be completely closed, and the light from the top and the sides can be blocked. A dark environment is formed around the detection bracket, which can improve the outdoor detection results. The operation is simple and the use is very convenient. When the eye examination machine is used indoors, the semi-light-shielding covers can be rotated toward both sides respectively. At this time, the two semi-light-shielding covers can be fully opened, thereby avoiding the semi-light-shielding covers interfering with the normal use of the eye examination host.

[0005] In order to solve the above technical problems, the technical solution of the utility model is achieved as follows:

[0006] A light-shielding support slide for a universal eye examination machine comprises a test bracket fixedly mounted on the front side of an eye examination host, the test bracket comprising a face support and a mandibular support, the mandibular support being located below the face support; both left and right sides of the test bracket are rotatably connected to semi-light-shielding covers via hinges, the semi-light-shielding covers being non-light-transmitting covers; the two semi-light-shielding covers can be completely closed by rotating toward the middle via hinges, thereby blocking light from the top and sides; the two semi-light-shielding covers can be completely opened by rotating toward both sides via hinges.

[0007] By adopting the above scheme, when the eye examination machine is used outdoors, the two semi-light-shielding covers can be rotated toward the middle respectively. At this time, the two semi-light-shielding covers can be completely closed, and the light from the top and the sides can be blocked. A dark environment is formed around the detection bracket, which can improve the outdoor detection results. The operation is simple and the use is very convenient. When the eye examination machine is used indoors, the semi-light-shielding covers can be rotated toward both sides respectively. At this time, the two semi-light-shielding covers can be fully opened, thereby avoiding the semi-light-shielding covers interfering with the normal use of the eye examination host.

[0008] As a preferred embodiment of a light-shielding support slide for a universal eye examination machine, a vertically arranged positioning cap head is fixedly installed above each semi-light-shielding cover body, and a non-elastic rope is fixedly connected between the two positioning cap heads, and the non-elastic rope is always in a stretched and taut state; a slide rail for use with the non-elastic rope is fixed above the chassis of the eye examination host, and a slide seat is slidably mounted on the slide rail; a vertically arranged pulling cap head is fixed to the upper surface of the slide seat, and the pulling cap head is located between the two positioning cap heads, and the middle part of the non-elastic rope is hooked on the pulling cap head;

[0009] The upper surface of the slide seat is threaded with a fastening screw, and the top of the fastening screw can contact the slide rail;

[0010] Wherein, side wings are fixed on both sides of the sliding seat, and the shape of the side wings is like the wings of an airplane;

[0011] Among them, an external expansion plate perpendicular to the detection bracket is fixedly installed at one end of the slide rail, and a vertically arranged external expansion cap head is fixedly installed at both ends of the external expansion plate. The non-elastic rope passes around the external expansion cap head and is hooked on the pulling cap head.

[0012] By adopting the above scheme, in order to facilitate the staff to quickly open the two semi-light-shielding covers, the staff can hold the side wings and slide the slide toward their own location. At this time, the two semi-light-shielding covers are pulled at the same time under the tension of the non-elastic rope, and the non-elastic rope is expanded outward under the action of the outward-expanding cap head, and then the slide is tightened by rotating the top screw, so that the two semi-light-shielding covers are fully opened.

[0013] As a preferred embodiment of a light-shielding support slide for a universal eye examination machine, a second positioning cap head is fixedly mounted above each semi-light-shielding cover body and is arranged concentrically with the hinge. An elastic rope is fixedly connected between the two positioning cap heads, and the elastic rope is always in a stretched and taut state.

[0014] Among them, a vertically arranged outward-facing cap head 2 is fixedly installed beside each positioning cap head 2; and both ends of the elastic rope are respectively passed around the outward-facing cap head 2 and then fixedly connected with the positioning cap head 2.

[0015] By adopting the above scheme, in order to facilitate the staff to quickly close the two semi-light-shielding covers, the fastening top screw is loosened. At this time, the slide seat is in a sliding state. Under the elastic pull of the elastic rope, the two opened semi-light-shielding covers gradually begin to close. The outward-expanding cap head 2 can further increase the elastic force of the elastic rope by expanding the elastic rope outward until the two semi-light-shielding covers are in a completely closed state.

[0016] After adopting the above technical solution, the beneficial effects of the utility model are:

[0017] 1. When the eye examination machine is used outdoors, the two semi-shading covers can be rotated toward the center. At this time, the two semi-shading covers can be completely closed, blocking light from the top and sides, forming a dark environment around the detection bracket, which can improve outdoor detection results. It is simple to operate and very convenient to use. When the eye examination machine is used indoors, the semi-shading covers can be rotated toward the sides. At this time, the two semi-shading covers can be fully opened, thereby preventing the semi-shading covers from interfering with the normal use of the eye examination host.

[0018] 2. To facilitate the staff to quickly open the two semi-shading hoods, the staff can hold the side wings and slide the slide towards their own direction. At this time, under the tension of the non-elastic rope, the two semi-shading hoods are pulled at the same time. Under the action of the outward-expanding cap head, the non-elastic rope expands outward, and then the slide is tightened by rotating the top screw, thereby fully opening the two semi-shading hoods.

[0019] 3. In order to facilitate the staff to quickly close the two semi-shading covers, loosen the fastening top screw. At this time, the slide seat is in a sliding state. Under the elastic pull of the elastic rope, the two opened semi-shading covers gradually begin to close. The second outward-expanding cap head can further increase the elastic force of the elastic rope by expanding the elastic rope outward until the two semi-shading covers are in a completely closed state.

[0033] like Figures 1 to 10As shown, a light-shielding support slide of a universal eye examination machine is used on an optometrist, which includes a detection bracket 1 fixedly mounted on the front side of an optometrist main unit 2, the detection bracket 1 including a face support 3 and a mandibular support 4, the mandibular support 4 being located below the face support 3; the left and right sides of the detection bracket 1 are both rotatably connected to a semi-light-shielding cover 6 via a hinge 5, and the semi-light-shielding cover 6 is a non-light-transmitting cover; the two semi-light-shielding covers 6 can be completely closed after being rotated toward the middle by the hinge 5, and can block light from the top and sides at this time; the two semi-light-shielding covers 6 can be completely opened after being rotated toward both sides by the hinge 5. When the ophthalmometer is used outdoors, the two semi-shading covers 6 can be rotated toward the middle respectively. At this time, the two semi-shading covers 6 can be completely closed, and the light from the top and the sides can be blocked. A dark environment is formed around the detection bracket 1, which can improve the outdoor detection results. It is simple to operate and very convenient to use. When the ophthalmometer is used indoors, the semi-shading covers 6 can be rotated toward the sides respectively. At this time, the two semi-shading covers 6 can be fully opened, thereby preventing the semi-shading covers 6 from interfering with the normal use of the optometry host 2.

[0034] like Figures 3 to 5 、 Figures 8 to 10 As shown, a vertically arranged positioning cap head 7 is fixedly installed above each semi-shading cover body 6, and a non-elastic rope 8 is fixedly connected between the two positioning cap heads 7, and the non-elastic rope 8 is always in a stretched and taut state; a slide rail 9 for use with the non-elastic rope 8 is fixed above the chassis of the optometry host 2, and a slide seat 10 is slidably mounted on the slide rail 9; a vertically arranged pulling cap head 11 is fixed to the upper surface of the slide seat 10, and the pulling cap head 11 is located between the two positioning cap heads 7, and the middle of the non-elastic rope 8 is hooked on the pulling cap head 11;

[0035] The upper surface of the slide 10 is threaded with a fastening screw 12, and the top of the fastening screw 12 can contact the slide rail 9;

[0036] Wherein, side wings 13 are fixed on both sides of the slide 10, and the shape of the side wings 13 is like the wings of an airplane;

[0037] Among them, the end of the slide rail 9 facing the detection bracket 1 is fixedly installed with an external expansion plate 14 perpendicular to it, and the two ends of the external expansion plate 14 are respectively fixedly installed with a vertically arranged external expansion cap head 15. The non-elastic rope 8 passes around the external expansion cap head 15 and is hooked on the pulling cap head 11.

[0038] In order to facilitate the staff to quickly open the two semi-light-shielding covers 6, the staff can hold the side wings 13 and slide the slide 10 towards their own location. At this time, the two semi-light-shielding covers 6 are pulled at the same time under the tension of the non-elastic rope 8, and the non-elastic rope 8 is expanded outward under the action of the outward-expanding cap head 15, and then the slide 10 is tightened by rotating the top screw 12, so that the two semi-light-shielding covers 6 are fully opened.

[0042] The working principle of this utility model:

[0043] When the ophthalmometer is used outdoors, in order to facilitate the staff to quickly close the two semi-shading covers 6, the fastening top screw 12 is loosened. At this time, the slide 10 is in a sliding state. Under the elastic pull of the elastic rope 17, the two opened semi-shading covers 6 gradually begin to close. The outer cap head 18 can further increase the elastic force of the elastic rope 17 by expanding the elastic rope 17 outward until the two semi-shading covers 6 are in a completely closed state. Figures 6 and 7 As shown, the light from the top and the side can be blocked at this time, and a dark environment is formed around the detection bracket 1, which can improve the outdoor detection results. It is simple to operate and very convenient to use.

[0044] When the ophthalmometer is used indoors, in order to facilitate the staff to quickly open the two semi-shading covers 6, the staff can hold the side wings 13 and slide the slide 10 in the direction of their own location. At this time, the two semi-shading covers 6 are pulled at the same time under the tension of the non-elastic rope 8. The non-elastic rope 8 is expanded outward under the action of the outward-expanding cap head 15, and then the slide 10 is tightened by rotating the top screw 12, so that the two semi-shading covers 6 are fully opened. Figures 1 to 2As shown, the semi-shielding cover 6 is prevented from interfering with the normal use of the optometry host 2.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
