[0027] Reference Figure 1 , Figure 6The present embodiment discloses a magnifying glass device for an insulin pen, including a mounting seat 3, a lens 15 detachably mounted on the mounting seat 3, and clamp arms 1 are provided on both sides of the mounting seat 3. The clamp arms 1 can produce a certain deformation or can be made of elastic material. One end of the clamp arm 1 is connected to the mounting seat 3, and the other end is provided with an anti-slip seat 2. The anti-slip seat 2 plays an anti-slip role. The inner side of the anti-slip seat 2 is provided with an anti-slip pad made of rubber and plastic material to increase the friction between the anti-slip seat 2 and the insulin pen, so that the connection of the mounting seat 3 is more stable and will not slide. A through hole for the insulin pen to pass through is formed between the clamp arms 1 on both sides of the mounting seat 3. In the present embodiment, two clamp arms 1 are provided, distributed on both sides of the mounting seat 3, referring to Figure 3 , pass the insulin pen through the perforation, and the clamping arms 1 on both sides clamp the entire mounting base 3 and position it on the insulin pen, so that the lens 15 corresponds to the position of the dial, and the scale value can be magnified through the lens 15 for clear observation.

[0028] The mounting seat 3 includes a seat body, a mounting groove 4 arranged on the seat body for accommodating a lens 15, and an upper cover 5 connected to the seat body. The upper cover 5 is detachably connected to the seat body, and a visual window 6 is arranged on the upper cover 5. One end of the upper cover 5 is rotatably connected to the seat body, and the other end is detachably connected to the seat body. The detachable connection can be achieved by a connecting structure such as a snap. After the lens 15 is installed in the mounting groove 4, the upper cover 5 is closed and fixed, and the reading is magnified through the window. Since the lens 15 will inevitably have scratches during long-term use, which will affect the reading, in order to facilitate the replacement of the lens 15, the upper cover 5 can be opened, and the lens 15 can be taken out of the mounting groove 4 for replacement. The structure is simple and practical. At the same time, the entire mounting seat 3 can be removed by the clamping arm 1 and installed on another insulin pen for use, thereby realizing multiple uses of one lens.

[0029] According to another embodiment of the present application, refer to Figure 2 In this embodiment, two clamping arms 1 are respectively provided on both sides of the mounting base 3, mainly to improve the stability of the installation of the magnifying glass device. Of course, the number of clamping arms 1 can be set according to actual conditions, and three or four clamping arms 1 can be installed on each side.

[0030] According to another embodiment of the present application, referring to Figure 4 The anti-slip seat 2 is detachably connected to the clamp arm 1. In order to facilitate the magnifying glass device to be suitable for insulin pens of different thicknesses, a threaded column 7 is provided at the bottom end of the anti-slip seat 2, and a threaded groove 8 adapted to the threaded column 7 is provided at the end of the clamp arm 1. The installation connection between the anti-slip seat 2 and the clamp arm 1 is achieved through the cooperation between the threaded column 7 and the threaded groove 8. The distance between the anti-slip seat 2 and the clamp arm 1 can also be controlled by the depth of the connection between the thread group and the threaded groove 8. The larger the distance, the thinner the anti-slip seat 2 can be used for insulin pens, which is more convenient to use.

[0031] According to another embodiment of the present application, referring to Figure 5 The anti-slip seat 2 is detachably connected to the clamp arm 1. In order to facilitate the magnifying glass device to be suitable for insulin pens of different thicknesses, another structure for connecting the anti-slip seat 2 and the clamp arm 1 is provided. A connecting column 9 is arranged at the bottom end of the anti-slip seat 2, and positioning blocks 11 are arranged on both sides of the connecting column 9. A cylindrical groove 10 is arranged at the end of the clamp arm 1. A spring 12 is arranged in the cylindrical groove 10. Two vertically distributed slide grooves 13 are arranged on both sides of the side wall of the cylindrical groove 10. Two groups of positioning grooves 14 are also arranged on the side wall of the cylindrical groove 10. The positioning groove 14 group includes a plurality of laterally distributed positioning grooves 14 arranged up and down. The positioning grooves 14 in each of the positioning groove groups 14 are connected to the corresponding slide grooves 13, and the slide grooves 13 and the positioning grooves 14 are both adapted to the positioning blocks 11. The bottom end of the spring 12 is fixedly connected to the cylindrical groove 10. The connecting column 9 can be inserted into the cylindrical groove 10, and the positioning groove 14 can be moved downward along the slide groove 13. At this time, the connecting column 9 also overcomes the elastic force of the spring 12 and moves downward until it moves to the corresponding position. The connecting column 9 is rotated so that the positioning groove 14 is inserted into the corresponding positioning groove 14 to realize the connection between the anti-slip seat 2 and the clamp arm 1. The positioning grooves 14 of different heights can realize the adjustment of different spacing distances, so that the anti-slip seat 2 can be suitable for insulin pens of different thicknesses.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
