[0024] 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.
[0025] This utility model provides a magnifying glass with charging function, as shown in Figures 1-5, comprising:
[0026] Equipment casing 1, mounting base 2, and magnifying lens 3;
[0027] Mounting base 2 is movably disposed in the inner cavity of the device housing 1. Magnifying lens 3 is installed inside mounting base 2. A control circuit board 4 is installed at the end of the inner cavity of the device housing 1 away from mounting base 2. A charging port 5 is installed at one end of the control circuit board 4. The end of the charging port 5 away from the control circuit board 4 extends to the outside of the device housing 1. A storage battery 6 is disposed below the control circuit board 4. An LED bead 7 is installed inside mounting base 2. A push-button control switch 8 is installed inside mounting base 2. The control switch is electrically connected to the control circuit board 4 and the LED bead 7 respectively. One end of the push-button control switch 8 extends through mounting base 2 and is attached to the inner wall of the device housing 1.
[0028] The magnifying glass lens 3 is installed via the mounting base 2, which can extend and retract within the device housing 1. When the mounting base 2 is pulled outward, the push-button control switch 8 on the mounting base 2 moves within the storage slot 10 and is pressed to illuminate the LED 7, thereby enhancing the light near the magnifying glass lens 3 and improving the observation effect. Furthermore, the magnifying glass lens 3 can be retracted into the device housing 1 along with the mounting base 2, preventing the magnifying glass lens 3 from being scratched.
[0029] As shown in Figure 3:
[0030] Mounting base 2 includes a fixed base 21 and a movable base 22. The fixed base 21 and the movable base 22 are provided with through holes. A limiting sleeve 9 is fixed on the opposite side of the fixed base 21 and the movable base 22. The limiting sleeve 9 is snapped onto the outside of the magnifying lens 3. By providing through holes in the fixed base 21 and the movable base 22, the use of the magnifying lens 3 is facilitated, allowing light to pass through the magnifying lens 3. At the same time, the limiting sleeve 9 fits against the magnifying lens 3 to limit the magnifying lens 3, maintain the stability of the magnifying lens 3 inside the mounting base 2, and ensure that the light emitted by the lamp bead 7 can penetrate the magnifying lens 3.
[0031] Furthermore, as shown in Figure 5:
[0032] A storage slot 10 is provided on the inner wall of the inner cavity of the device housing 1. The push-button control switch 8 is located in the storage slot 10. The end of the storage slot 10 away from the control circuit board 4 is set at an angle. The storage slot 10 facilitates the storage of the push-button control switch 8. At the same time, the limitation of the structure of the storage slot 10 makes it easy to press the push-button control switch 8 after the mounting base 2 is removed from the device housing 1 and the magnifying glass lens 3 is completely exposed, so as to realize the automatic lighting of the lamp bead 7.
[0033] Preferably, as shown in Figure 3-5:
[0034] A limiting groove 11 is provided on the inner side wall of the equipment housing 1, and a limiting block 12 is fixed on the outer side of the mounting base 2. The limiting block 12 is slidably disposed in the limiting groove 11. By sliding the limiting block 12 in the limiting groove 11, not only can the stability of the mounting base 2 inside the equipment housing 1 be maintained, but the movement distance of the mounting base 2 is also limited. On the one hand, this prevents the mounting base 2 from contacting the control circuit board 4, and on the other hand, it limits the distance that the mounting base 2 moves out.
[0035] It is worth noting, as shown in Figure 3:
[0036] The movable base 22 has a slot 13, and the fixed base 21 has a fixed post 14. The fixed post 14 is engaged in the slot 13. By engaging the fixed post 14 on the fixed base 21 with the slot 13 on the movable base 22, it is convenient to fix the movable base 22 and the fixed base 21, and at the same time, it is used to limit the stability of the magnifying lens 3.
[0037] In a further preferred embodiment, as shown in Figures 1-3:
[0038] A push-pull head 15 is fixed at the end of the mounting base 2 away from the equipment housing 1. The size of the push-pull head 15 is larger than the size of the equipment housing 1. The push-pull head 15 facilitates the push-pull movement of the mounting base 2.
[0039] Additionally, as shown in Figures 1 and 5:
[0040] The control circuit board 4 is also equipped with a charging indicator light 16. The charging indicator light 16 is embedded on the outside of the device housing 1. The setting of the charging indicator light 16 makes it easy to observe whether the charging is connected and avoids the charging port 5 being loosely connected to the plug.
[0041] In actual use, the battery 6 is fully charged through the charging port 5. When the magnifying lens 3 is needed, the mounting base 2 is moved outward by the push-pull head 15. The mounting base 2 slides outward in the limiting groove 11 through the limiting block 12. When the magnifying lens 3 is completely exposed outside the device housing 1, the push-type control switch 8 on the mounting base 2 moves along the storage groove 10 and contacts the inclined surface in the storage groove 10. It is pressed down to light up the lamp 7. The light emitted by the lamp 7 is scattered outward through the magnifying lens 3, forming an illumination area around the magnifying lens 3, which makes it easier for the user to observe objects through the magnifying lens 3.
[0042] 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.
