Description

Technical Field

[0001] This utility model relates to the field of pupil detection technology, specifically a terminal connection device for a pupil detector. Background Technology

[0002] The pupil is a small, round opening in the center of the iris of an animal or human eye, serving as the passage for light to enter the eye. The contraction and expansion of the smooth muscle in the iris can constrict or dilate the pupil, controlling the amount of light entering. It is a constrictible opening in the iris, and in most vertebrates, it remains circular whether enlarged or constricted. Iris detectors are developed using high-tech methods. Iris diagnosis accurately detects toxins, nutrients, and health conditions in the body to analyze and understand the root causes of problems, thus providing a scientific basis for health care. The iris, a part of the eye's structure, has a circular opening in its center called the pupil, much like the adjustable aperture in a camera. It contains pigments that determine the color of the eye.

[0003] Currently, when using pupil detector terminals, cables are usually connected. However, the cables of existing terminals are generally exposed, which are not only susceptible to wear and tear from being stepped on, but also easily pulled by the excess cable, resulting in significant cable loss during use and affecting the service life. Utility Model Content

[0004] The purpose of this invention is to provide a terminal connection device for a pupil detector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pupil detector terminal connection device, including a protective shell, and further comprising:

[0006] A cover plate is provided on the top of the protective shell. A slot is provided on one side of the protective shell. A positioning shell is fixedly connected to the bottom of the inner cavity of the protective shell. A terminal connection cable is provided inside the protective shell. Connecting shells are fixedly connected to both the front and rear sides of the inner cavity of the protective shell. A winding component for winding the cable is provided inside the cover plate. The winding component includes a rotating rod.

[0007] Positioning plates are fixed to both sides of the bottom of the inner cavity of the protective shell. An installation assembly is provided inside the connecting shell, and the installation assembly includes a first toothed plate and a second spring.

[0008] Preferably, a first spring is fixedly connected to one side of the positioning plate, and a movable frame is fixedly connected to one side of the first spring. A roller is provided inside the movable frame.

[0009] Preferably, a limiting rod is fixedly connected to one side of the movable frame, and one side of the limiting rod extends to the outside of the positioning plate.

[0010] Preferably, a rubber pad is fixedly connected to the bottom of the cover plate, and a sealing groove for use with the rubber pad is provided on the top of the protective shell.

[0011] Preferably, the first toothed plate is fixed to the front and rear sides of the bottom of the cover plate, the second spring is fixed to one side inside the connecting shell, the other side of the second spring is fixedly connected to the second toothed plate, one side of the second toothed plate is fixedly connected to the push rod, one end of each push rod extends to the outside of the protective shell, and a push plate is fixedly connected between the two push rods.

[0012] Preferably, the rotating rod is disposed inside the cover plate, a torsion block is fixedly connected to the top of the rotating rod, a winding post is fixedly connected to the surface of the rotating rod, and a positioning ring is fixedly connected to the top of the surface of the rotating rod.

[0013] Preferably, a rubber strip is fixedly connected to the surface of the winding column, and a buckle is fixedly connected to one side of the winding column.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention firstly allows the rotating rod to rotate inside the positioning shell by twisting the torsion block. As the rotating rod rotates, it also drives the winding column to rotate, thereby locking onto the cable surface through the buckle and then rotating and winding it up. This reduces the length of the cable exposed to the outside, protecting it and reducing wear. When the cable needs to be removed for maintenance, simply press the push plate to make the push rod drive the second toothed plate to squeeze the second toothed plate against the second spring, causing the second toothed plate to separate from the surface of the first toothed plate. Then the cover plate can be removed for maintenance. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, a pupil detector terminal connection device includes a protective shell 1 and a cover plate 2 disposed on the top of the protective shell 1. A rubber pad 14 is fixedly connected to the bottom of the cover plate 2. The sealing performance between the cover plate 2 and the protective shell 1 can be improved by the rubber pad 14 cooperating with the sealing groove 15. A sealing groove 15 for use with the rubber pad 14 is opened on the top of the protective shell 1. A slot 3 is opened on one side of the protective shell 1. A positioning shell 4 is fixedly connected to the bottom of the inner cavity of the protective shell 1. The positioning shell 4 facilitates the winding of the cable. A terminal connection cable 5 is disposed inside the protective shell 1. A connection shell 6 is fixedly connected to both the front and rear sides of the inner cavity of the protective shell 1. A winding component 7 for winding the cable is disposed inside the cover plate 2. The winding component 7 includes a rotating rod 701.

[0023] Positioning plates 8 are fixed to both sides of the bottom of the inner cavity of the protective shell 1. An installation component 9 is provided inside the connecting shell 6. The installation component 9 includes a first toothed plate 901 and a second spring 902.

[0024] A first spring 10 is fixedly connected to one side of the positioning plate 8, and a movable frame 11 is fixedly connected to one side of the first spring 10. When the cable is wound up, the two rollers 12 will contact the surface of the cable. The movable frame 11 will also drive the first spring 10 to protect and wind up the terminal connection cable 5 between the positioning plates 8. The movable frame 11 is equipped with rollers 12 inside. A limit rod 13 is fixedly connected to one side of the movable frame 11. The limit rod 13 can improve the stability of the movable frame 11 when it moves. One side of the limit rod 13 extends to the outside of the positioning plate 8.

[0025] The first toothed plate 901 is fixed to the front and rear sides of the bottom of the cover plate 2. The second spring 902 is fixed to one side inside the connecting shell 6. The other side of the second spring 902 is fixedly connected to the second toothed plate 903. One side of the second toothed plate 903 is fixedly connected to the push rod 904. One end of both push rods 904 extends to the outside of the protective shell 1. When the cover plate 2 needs to be removed to maintain the cables inside the protective shell 1, the push plate 905 can be pushed to move the push rod 904. At this time, the push rod 904 will cause the second toothed plate 903 to squeeze the second spring 902. Then the second toothed plate 903 will detach from the surface of the first toothed plate 901, and the push plate 905 is fixedly connected between the two push rods 904.

[0026] The rotating rod 701 is located inside the cover plate 2. A torsion block 702 is fixedly connected to the top of the rotating rod 701. A winding post 703 is fixedly connected to the surface of the rotating rod 701. A positioning ring 706 is fixedly connected to the top of the surface of the rotating rod 701. A rubber strip 704 is fixedly connected to the surface of the winding post 703. By twisting the torsion block 702, the rotating rod 701 can be rotated inside the positioning shell 4. When the rotating rod 701 rotates, it will also drive the winding post 703 to rotate, thereby locking it onto the surface of the cable through the buckle 705 and then rotating and winding it up, thereby reducing the length of the cable exposed to the outside, protecting it and reducing wear. A buckle 705 is fixedly connected to one side of the winding post 703.

[0027] Working principle: First, the push plate 905 causes the push rod 904 to drive the second toothed plate 903 to squeeze the second spring 902, causing the second toothed plate 903 to separate from the surface of the first toothed plate 901. Then, the cover plate 2 can be removed. Then, the terminal connection cable 5 is inserted through the slot 3 of the protective shell 1 and threaded into the inside of the buckle 705. Then, the plug of the terminal connection cable 5 is threaded into the other side of the inner wall of the protective shell 1 and fixed. Then, the cover plate 2 is installed. Then, the torsion block 702 can be turned to make the rotating rod 701 rotate inside the positioning shell 4. When the rotating rod 701 rotates, it will also drive the winding column 703 to rotate, thereby locking the cable surface through the buckle 705 and then rotating and winding, thereby reducing the length of the exposed cable and protecting it from wear. When the cable is wound, the two rollers 12 will contact the cable surface, and the movable frame 11 will also drive the first spring 10 to protect and wind the terminal connection cable 5 between the positioning plates 8.
