[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] It should be noted that the structures not introduced in the present invention do not involve the design points and improvement directions of the present invention, and all adopt the existing technology. The above contents belong to the technical cognition scope of the utility model author. Since the technical content in this field is vast and too complicated, the above contents of this application do not necessarily constitute the prior art.

[0037] Reference Figure 1-5 The present embodiment provides an integrated power supply structure for a retinoscope, including a handle housing 1 (plastic), a dimming knob 2 (plastic), a potentiometer paddle 3, a handle joint base 4 (metal), a handle joint locking ring 5 (metal), a battery compartment 6 (plastic), a battery 7, a power control circuit board 8, a central conductive sheet 9 (metal), a side conductive sheet 10 (metal), a spring 11, a middle battery cell 12 (metal), a middle battery cell seat 13 (plastic), a handle joint 14 (metal), and a potentiometer 15.

[0038] Among them, the pins of the potentiometer are inserted into the pads of the power control circuit board 8 and fixed by soldering. When assembling, they are first inserted into the battery compartment 6. There are limit and position buckles on the battery compartment 6. After insertion, the pins will pass through the power control circuit board 8 at the same time.

[0039] Among them, the potentiometer paddle 3 is arranged in a preset cavity of the handle joint base 4, and a central conductive sheet 9 and a middle battery seat 13 are installed in the handle structure base 4 and above the potentiometer paddle 3, and the handle structure base 4 is housed in the dimming knob 2.

[0040] A central conductive sheet 9 is provided on the bottom surface of the central battery seat 13, a central battery cell 12 is provided on the top of the central battery seat 13, and a limiting cavity for accommodating the extrusion of the spring 11 is provided inside the central battery seat 13. When the main body mechanism is connected, the central battery cell 12 is connected to the central conductive sheet 9 through the extrusion process of the spring 11.

[0041] The basic function of this embodiment needs to realize that the dimming knob 2 can be rotated manually, driving the potentiometer paddle 3 to rotate, and finally rotating the knob in the middle of the potentiometer 15, thereby changing the voltage to adjust the brightness. During the adjustment and rotation process, normal operation can be ensured, and the positive and negative electrodes need to be connected to the top main body mechanism (such as a light bulb). The main way to achieve this is:

[0042] Install the side conductive sheet 10 on the battery compartment 6, fix it by hot-melting the plastic columns at both ends, then weld a shorter negative wire to the negative output terminal 8 of the power control circuit board and the side conductive sheet 10, and weld a longer positive wire to the protruding section of the center conductive sheet 9. Note that the wire needs to pass through the hole structure designed in the battery compartment 6 to prevent interference with the subsequent assembly wires. At this point, the center conductive sheet 9 and the side conductive sheet 10 are both conductive to the corresponding electrodes.

[0043] Then the entire battery compartment 6 is inserted into the handle housing 1 to complete the installation, wherein the central conductive sheet 9 contacts and conducts electricity with the spring 11, and the spring 11 supports the middle battery cell 9 to contact and conduct electricity, and finally the middle battery cell 12 can contact and conduct electricity with the main body mechanism above.

[0044] The side conductive sheet 10 is structured through an elastic sheet metal structure, so that the extended leg of the handle joint base 4 is inserted into the sheet metal elastic clip during assembly, so that the contact is good and conductive, thereby conducting the negative electrode to the handle joint base 4. Because the handle joint 14 is locked to the handle joint base 4 by the handle joint 5 locking ring, the negative electrode is well conducted to the handle joint 14, and finally the handle joint 14 is negatively charged and can contact and conduct with the main body mechanism above.

[0045] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
