Description
Technical Field
The utility model relates to a microscope technical field specifically is a control prism shell.
Background
The microscope is an optical instrument formed by one lens or a combination of a plurality of lenses, is a mark for human beings to enter the atomic era, is mainly used for magnifying tiny objects to be seen by naked eyes of the human beings, and is an important instrument essential for ophthalmic examination. The slit-lamp microscope consists of an illumination system and a binocular microscope, can enable superficial lesions to be observed clearly, can adjust the focal point and the light source width to be made into an optical section, enables deep tissue lesions to be displayed clearly, and needs to open or close left and right prism shells when adjusting the interpupillary distance, and the prism shells common in the market are not provided with convex ribs and are easy to slip when being moved open; only one finger is used for the function of one finger in some cases; some prism shells have a plurality of upper half-rings, which affect the appearance, and for this reason, a left prism shell and a right prism shell are provided to solve the problems.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome current defect, provide one kind and control prism shell, structural design is reasonable, can increase finger grip, pull and hold and be difficult to skid, and the practicality is strong, and the structure is pleasing to the eye moreover, has promoted the experience when using and has felt, can effectively solve the problem in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: a left prism shell and a right prism shell comprise rib assemblies and supporting seats;
supporting seat: the front end of the prism shell is rotationally connected with two prism shells which are symmetrically distributed;
rib subassembly: including first protruding muscle, the protruding muscle of second and the protruding muscle of third, first protruding muscle, the protruding muscle of second and the protruding muscle of third are by outer to interior setting in the upper end of prism shell, and structural design is reasonable, can increase and point the power of holding tightly, pulls open and holds tightly and be difficult to skid, and the practicality is strong, and the structure is pleasing to the eye moreover, has promoted the experience when using and has felt.
Furthermore, the radiuses of the first protruding ribs, the second protruding ribs and the third protruding ribs are 1mm, 1.5mm and 1.3mm in sequence, and the anti-skidding effect on fingers is increased.
Furthermore, the included angle between the first protruding rib and the third protruding rib is 17 degrees relative to the vertical plane where the second protruding rib and the circle center of the prism shell round hole are located, the position of a finger when the finger is placed naturally is adapted, and the practicability is improved.
Further, the length of first protruding muscle, the protruding muscle of second and the protruding muscle of third is 21mm, 35mm and 28mm in proper order, carries out length setting according to people's finger length, practices thrift the cost, guarantees the travelling comfort when people's finger pulls the prism shell simultaneously.
Compared with the prior art, the beneficial effects of the utility model are that: this left and right sides prism shell has following benefit:
first protruding muscle, the protruding muscle of second and the protruding muscle of third are located forefinger, middle finger, ring finger respectively and hold the position of prism shell tightly, when need pull open or close up about the prism shell, can increase finger grip, pull open and hold tightly and be difficult to skid, and the practicality is strong, and the structure is pleasing to the eye moreover, has promoted the experience when using and has felt.
