Description

Technical Field

[0001] This utility model relates to the field of children's toy technology, specifically a children's microscope. Background Technology

[0002] Children's microscopes are photoelectric instruments used for children's learning and observation. They help cultivate children's interest in learning and their imagination. As people's living standards improve, learning is no longer limited to textbook knowledge, and scientific exploration is receiving increasing attention. Children's microscope toys allow children to see the microscopic world, a world that cannot be directly observed with the naked eye. When they see the cellular structure of leaves, the scales on insect wings, or microorganisms in water through a microscope, they develop a strong curiosity about the world around them.

[0003] A search revealed that Chinese Patent Publication No. CN213432997U discloses a children's toy microscope, comprising a base with a specimen turntable for placing specimens on the base, an arc-shaped microscope frame on the side of the base, and a microscope tube assembly aligned with the center of the specimen turntable on the microscope frame. A downward-extending rack is provided on the side wall of the microscope tube assembly, and a gear is fitted on the rack to drive its up-and-down movement. The gear is fitted around a rotating shaft that passes through the microscope frame and is located inside the microscope frame. An adjustment knob connected to the rotating shaft is located on the side of the rotating shaft extending out of the microscope frame. The rotating shaft is parallel to the base. The microscope tube assembly includes a lower and upper microscope tube connected by threads, with a replaceable magnifying lens placed between the lower and upper microscope tubes. The rack is located outside the lower microscope tube. This structure allows adjustment of the magnifying lens and its height to ultimately meet user needs.

[0004] However, this device also has the following drawbacks:

[0005] When children use a microscope, they may press their eyes close to the eyepiece to see more clearly. The microscope tube assembly protrudes from the main structure, which may cause damage to children's eyes. Furthermore, the device adjusts the vertical position of the microscope tube assembly to focus, further increasing the possibility of eye damage to children. This device does not address this problem. Utility Model Content

[0006] The purpose of this invention is to provide a children's microscope that uses a binocular structure to make the microscope tube rounded, increasing the contact area with the child's face and thus reducing the risk of damage to the child's eyes. Furthermore, it uses the stage to adjust the microscope tube instead of adjusting the microscope tube for focusing, preventing damage to the child's eyes during focusing, thereby solving the problems mentioned in the background art.

[0012] Preferably, the first gear, the second gear, and the screw are disposed inside the base, and the bottom of the second gear is integrally formed with a second connecting post, which is rotatably engaged with the bottom inner wall of the base.

[0013] Preferably, two sets of sliding sleeves are fixedly installed at the bottom of the platform, the sliding sleeves are slidably engaged with the top of the guide rod, and the bottom of the guide rod is fixedly installed on the bottom inner wall of the base.

[0014] Preferably, a protective cover is provided on the outer side of the first lens, the protective cover is fixedly connected to the lens barrel, and the protective cover is made of silicone material.

[0015] Preferably, two sets of LED beads are installed at the bottom of the lens barrel, and the LED beads are located on both sides of the second lens.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model features a simple and convenient structure with a lens barrel and base for combined use. The rounded shape of the main body makes it easy for children to use and less likely to cause injury.

[0022] 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.

[0023] Please see Figures 1-3 This utility model provides a technical solution:

[0024] A children's microscope includes a main structure, which includes a microscope tube 1. A base 2 is fixedly installed at the bottom of the microscope tube 1. Two sets of first lenses 4 are fixedly installed at the top of the microscope tube 1. A second lens 10 is fixedly installed at the bottom of the microscope tube 1. A protective cover 3 is provided on the outside of the first lenses 4. The protective cover 3 is fixedly connected to the microscope tube 1. The protective cover 3 is made of silicone material. Two sets of LED beads 9 are installed at the bottom of the microscope tube 1. The LED beads 9 are located on both sides of the second lens 10.

[0025] By designing the lens barrel 1 as a binocular structure, its rounded shape makes it easy for children to use and increases the contact area with children's faces, thereby reducing the risk of damage to children's eyes. The protective cover 3 prevents the relatively hard lens barrel 1 from directly contacting children's faces, further protecting children's eyes. The protective cover 3 can be made into various animal shapes, thereby increasing the fun for children to use. The LED light beads 9 are also included to improve the observation effect in low light conditions.

[0026] It also includes a base 2, a mounting seat 5 is fixedly installed on the top of the base 2, a platform 6 is slidably installed in the middle of the mounting seat 5, two sets of sliding sleeves 17 are fixedly installed on the bottom of the platform 6, the sliding sleeves 17 are slidably engaged with the top of the guide rod 18, and the bottom of the guide rod 18 is fixedly installed on the bottom inner wall of the base 2.

[0027] By using the base 2 in conjunction with the lens barrel 1, the main structure can be made rounded, making it easier for children to use and reducing the possibility of injury to children. By using the mounting base 5, sliding sleeve 17 and guide rod 18 in conjunction with the stage 6, the rotation of the stage 6 can be prevented, and the direction of movement of the stage 6 is limited, thus facilitating focusing.

[0028] It also includes an adjustment assembly, which includes an adjustment knob 7. A first gear 11 is fixedly installed at the bottom of the adjustment knob 7. The first gear 11 meshes with a second gear 13. A screw 15 is fixedly installed at the top of the second gear 13. The top of the screw 15 is threadedly connected to a connecting seat 16 fixedly installed at the bottom of the platform 6. The adjustment knob 7 is rotatably installed in an adjustment groove 8 opened on one side of the bottom of the base 2. A first connecting post 12 is integrally formed at the bottom of the adjustment knob 7. The first connecting post 12 is rotatably engaged with the bottom inner wall of the base 2. The first gear 11, the second gear 13 and the screw 15 are disposed inside the base 2. A second connecting post 14 is integrally formed at the bottom of the second gear 13. The second connecting post 14 is rotatably engaged with the bottom inner wall of the base 2.

[0029] By setting the adjustment knob 7, the first gear 11 can be rotated, which in turn drives the second gear 13 to rotate, causing the screw 15 to rotate. The connecting seat 16, which is threaded into the screw 15, moves the stage 6 up and down, so that the object being observed on the stage 6 moves closer to or further away from the lens barrel 1, thereby achieving focus. By adjusting the stage 6 instead of adjusting the lens barrel 1 for focusing, the movement of the lens barrel 1 during focusing can be prevented from causing damage to the child's eyes.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
