[0033] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0034] Example:

[0035] See also Figure 1-Figure 4A micro DC operating power supply includes a chassis 1, a connecting plate 2, a battery box 3, a cover plate 4, a pressure rod 5 and a power button 6. Specifically, the chassis 1 is provided with necessary electronic components and circuit boards of the DC operating power supply, a battery slot 7 is provided at the bottom of the chassis 1, and one end of the battery slot 7 is open, and the opening structure is located at the side of the chassis 1, and a slide slot 8 is provided above the battery slot 7, the width of the slide slot 8 is equal to the width of the opening structure of the battery slot 7, and the height of the slide slot 8 is greater than the height of the opening structure of the battery slot 7.

[0036] A cover plate 4 is slidably disposed in the slide groove 8 , and the height of the cover plate 4 is greater than the height of the opening structure of the battery slot 7 , so that the cover plate 4 can completely cover the opening structure of the battery slot 7 .

[0037] A control groove 9 recessed into the chassis 1 is also provided inside the slide groove 8, and a pressure rod 5 is rotatably provided in the control groove 9, wherein one end of the pressure rod 5 is rotatably connected to the inner wall of the control groove 9, and the length direction of the pressure rod 5 is on a vertical plane, and the end of the pressure rod 5 rotatably connected to the control groove 9 is close to the battery slot 7.

[0038] A power button 6 is also arranged in the end of the control slot 9 away from the rotational connection with the pressure rod 5, and the other end of the pressure rod 5 is in contact with the power button 6, so that the pressure rod 5 can directly touch the button when rotating.

[0039] In addition, a connecting plate 2 is provided inside the battery slot 7, and the connecting plate 2 is located in the middle of the end of the battery slot 7 away from the opening structure. A battery box 3 can be inserted into the battery slot 7, and batteries are arranged in the battery box 3. At the same time, a concave connecting groove is provided at one end of the battery box 3. When the battery box 3 is inserted into the battery slot 7, the connecting plate 2 and the connecting groove can match.

[0040] Among them, a plurality of electrode plates matching each other are arranged on the connecting plate 2 and in the connecting groove, and the power connection between the batteries in the battery box 3 and the electronic components in the chassis 1 is realized through the electrode plates on the connecting plate 2 and the connecting groove.

[0041] In this embodiment, a battery slot 7 is provided at the bottom of the chassis 1 of the power supply, and a slide groove 8 is provided on one side of the battery slot 7. When the battery of the power supply is removed or installed, the cover plate 4 is pushed to slide in the slide groove 8 so that it slides to the top of the battery slot 7 and the battery slot 7 is completely exposed, so that the battery box 3 can be installed in the battery slot 7, or the battery box 3 in the battery slot 7 can be taken out. The battery box 3 is installed with batteries, and the batteries are electrically connected to the electronic components in the chassis 1 through the cooperation of the connecting groove on the battery box 3 and the connecting plate 2 in the battery slot 7.

[0042] Generally, after the cover 4 slides up, it indicates that corresponding action needs to be taken on the battery box 3. At this time, it is necessary to avoid frequent power-on and power-off of the electronic components in the chassis 1. Therefore, the above-mentioned power button 6 is connected in series between the electrode plate on the connecting plate 2 and the electronic components in the chassis 1. When the cover 4 slides up and the pressure rod 5 is pressed down, the power button 6 is triggered. At this time, the circuit between the electrode plate on the connecting plate 2 and the electronic components in the chassis 1 is disconnected.

[0043] Through this technical solution, the detachable management of the micro DC operating power supply battery is achieved, thereby facilitating operations such as battery maintenance.

[0044] In one specific embodiment:

[0045] The micro DC operating power supply also includes a torsion spring 10, which is arranged in the control slot 9 and is close to one end of the pressure rod 5 that is rotatably connected to the inner wall of the control slot 9. One end of the torsion spring 10 is connected to the inner wall of the control slot 9, and the other end is connected to the pressure rod 5. The torsion spring 10 can drive the end of the pressure rod 5 to move outside the control slot 9, so that after the cover plate 4 covers the opening structure of the battery slot 7, the end of the pressure rod 5 can release the power button 6, so that the electrode plate on the connecting plate 2 is connected to the electronic components in the chassis 1.

[0046] In another specific embodiment:

[0047] The end of the pressure rod 5 away from the rotational connection with the inner wall of the control groove 9 is L-shaped, and this end of the pressure rod 5 is in contact with the power button 6. The L-shaped end of the pressure rod 5 can better touch the power button 6 to prevent the power button 6 from affecting the rotation of the pressure rod 5.

[0048] In another specific embodiment:

[0049] A guide plate 11 is provided at the top or bottom of the battery slot 7. When a guide plate 11 is provided at the top of the battery slot 7, a guide groove 12 is provided at the top surface of the battery box 3. When a guide plate 11 is provided at the bottom of the battery slot 7, a guide groove 12 is provided at the bottom of the battery box 3.

[0050] By providing the guide plate 11 and the guide groove 12 , on the one hand, the process of the battery box 3 entering the battery slot 7 is smoother, and on the other hand, the phenomenon of the battery box 3 being inserted into the battery slot 7 inversely is avoided.

[0051] In another specific embodiment:

[0052] A handle is provided in the middle of the cover plate 4 to facilitate the sliding of the cover plate 4 in the slide groove 8 .

[0053] The bottom of the cover plate 4 is provided with a raised limiting portion 13, and the bottom of the battery slot 7 is provided with a limiting groove, into which the limiting portion 13 can be inserted. The limiting portion 13 and the limiting groove prevent the cover plate 4 from falling off from the slide groove 8.

[0054] The limiting portion 13 is provided with a groove, in which a slidable limiting rod 14 is transversely provided, one end of the limiting rod 14 passes through the side of the limiting portion 13, and a spring 15 is provided between the other end of the limiting rod 14 and the inner wall of the groove. By providing the limiting rod 14, the position of the cover plate 4 can be directly limited, so that the cover plate 4 will not be easily opened, thereby avoiding misoperation.

[0055] A limit plate is provided on the limit rod 14, and a spring 15 is sleeved on the limit rod 14 and abuts against the limit plate. A movable groove is provided on one side of the limit groove, and one end of the pressure rod 5 penetrates into the movable groove, and a movable block 16 is provided at this end of the pressure rod 5, and a concave slot is provided on the movable block 16.

[0056] When the cover 4 needs to be opened, a tool is inserted into the slot and the movable block 16 is driven through the slot to drive the limit rod 14 to move, and then the limit rod 14 is received into the groove in the limit portion 13, so that the cover 4 can slide smoothly in the slide groove 8.

[0057] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description 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.
