Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to 5, the present invention provides an embodiment: an ophthalmoscope eyepiece laser protective cover comprises a crank rod 2, a first tube seat 7 and a second tube seat 8; the number of the two crank rods 2 is two, the bottom ends of the two crank rods 2 are welded with a bottom mounting plate 1 together, and the two bottom mounting plates 1 are provided with mounting holes 6 in the shape of waist-round notches; a first welding plate 3 and a second welding plate 4 are respectively welded at two ends of the crank rod 2; the first pipe seat 7 and the second pipe seat 8 are both of cavity seat structures, the top surfaces of the first pipe seat and the second pipe seat are vertically penetrated with a semi-arc pipe cavity-shaped shield 10, and the top end of the shield 10 is provided with a shield top protection plate 11; the outer surface of the protective cover 10 is welded with a holding rod 9, so that the holding rod 9 makes the protective cover 10 constitute an opening and pulling mechanism.

Wherein: as shown in fig. 1 and fig. 3, the middle positions of the tops of the first tube seat 7 and the second tube seat 8 are vertically provided with outward extending partition plates 12, the top sections of the partition plates 12 are respectively welded with an arc-tube-cavity-shaped reinforcing tube 13, and the arrangement of the two tube seats improves the use strength of the first tube seat 7 and the second tube seat 8 which are positioned at the bottoms of the two buckling cavities.

Wherein: the division plates 12 at the middle sections of the first tube seat 7 and the second tube seat 8 are provided with round through holes, the round through holes are matched with the two turning rods 2 in a sliding mode through the through holes, the first tube seat 7 and the second tube seat 8 are communicated with the protective cover 10 penetrating through the tops of the first tube seat 7 and the second tube seat 8 to form a cavity, therefore, the first tube seat 7 and the second tube seat 8 which slide at the bottoms of the first tube seat 7 and the second tube seat 8 can slide left and right on the two turning rods 2, after the first tube seat 7 and the second tube seat 8 slide, separation and combination can be formed, when the first tube seat 7 and the second tube seat 8 are fixed on a microscope for use, an ocular lens on the microscope can be buckled in an inner cavity after combination, the dustproof purpose is achieved, when the holding rods 9 are held by hands to pull the holding rods outwards, and eyes of a user can be.

Wherein: the two ends of the crank lever 2 are sleeved with a spring 5 for pulling the two shields 10 outwards and rebounding and retracting after use, so that the two ends of the two springs 5 are respectively supported on the first welding plate 3 and the partition plate 12.

The working principle is as follows: when the device is used, the first tube seat 7 and the second tube seat 8 at the bottom are fixed at the top of a microscope, the two tube seats are provided with the protective covers 10 at the tops of the two tube seats and just can be buckled and pressed on the outer sides of the eyepieces of the microscope to protect the eyepieces, the protective cover top protecting plates 11 at the tops of the protective covers 10 can also form protection on the tops of the eyepieces, when the device is used, the two hands pull the holding rods 9 to pull the protective covers 10 outwards, so that the protective eyepieces are opened to protect the eyepieces of the microscope, and the device is convenient for people to watch and use. After use, the spring 5 can rebound and reset.
