[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] See also Figure 1-6 The present embodiment provides a multifunctional power supply box, including a box body 1 and a box cover 11 of the power supply box. Specifically, the power supply box is a power supply box of reference model HK-3000W, and the box cover 11 is rotatably connected to the upper end of the box body 1. The upper end of the box body 1 can be closed by rotating the box cover 11 to cover the upper end of the box body 1. A battery and a circuit board are arranged inside the box body 1, and a control panel is arranged at the upper end of the box body 1. The control panel includes a display screen, a knob, a switch and a button. The display screen is used to display the power output power, the battery power, etc., and the knob, the switch and the button are used to control the use of the box body 1 (circuit opening, voltage control, interface control, etc.).

[0025] After removing the control panel from the upper end of the box 1, the remaining area is small, resulting in fewer power output terminals. In order to increase the upper surface area of ​​the box 1, a plurality of telescopic seats 2 are slidably inserted into the upper end of the box 1. Specifically, a mounting groove is provided at the upper end of the box 1, and a plurality of mounting grooves are provided. A sliding seat 22 is fixedly connected to the lower end of the telescopic seat 2. The sliding seat 22 and the telescopic seat 2 are slidably inserted into the mounting groove, such as Figure 2 As shown, a first elastic member 4 is installed in the installation groove of the box body 1. The first elastic member 4 is configured as a spring, and the upper end of the first elastic member 4 is fixedly connected to the lower end of the sliding seat 22. The first elastic member 4 applies an upward elastic force to the sliding seat 22.

[0026] The elastic force of the first elastic member 4 drives the sliding seat 22 to slide upward in the installation slot, thereby driving the telescopic seat 2 to extend from the slot opening of the installation slot. Figure 2 and Figure 4 As shown, the outer wall of the telescopic seat 2 extending from the notch of the installation slot is installed with multiple output interfaces 21, that is, the front and rear end faces, the two side walls and the upper end face of the telescopic seat 2 are provided with output interfaces 21. The multiple output interfaces 21 are respectively set as power sockets, AC sockets, DC sockets, USB interfaces and Type-C interfaces to be suitable for power supply of a variety of different devices, among which the number of power sockets, USB interfaces and Type-C interfaces is relatively large. The telescopic seat 2 is connected to the circuit board circuit inside the box 1, and the circuit board is connected to the battery circuit inside the box 1. The battery is used as the power source to output the rated power to the output interface 21 through the circuit board.

[0027] The telescopic seat 2 extending from the notch of the installation slot increases the upper surface area of ​​the box body 1 so that multiple output interfaces 21 can be provided. The output interfaces 21 are connected to the device lines to facilitate simultaneous power supply to multiple devices.

[0028] Before use, the box cover 11 is closed on the upper end of the box body 1, and the weight of the box cover 11 applies downward pressure to the telescopic seat 2, driving the telescopic seat 2 to shrink into the installation groove. At this time, the first elastic member 4 shrinks. After the box cover 11 is opened, the box cover 11 cancels the pressure on the telescopic seat 2, and the elastic force of the first elastic member 4 on the sliding seat 22 drives the telescopic seat 2 to extend from the notch of the installation groove.

[0029] The elastic force exerted by the first elastic member 4 on the sliding seat 22 drives the sliding seat 22 to extend out of the mounting slot. In order to limit the sliding of the sliding seat 22, the side wall of the sliding seat 22 is fixedly connected to the limiting plate 221. Figure 3 As shown, a second limiting groove is provided on the inner side wall of the installation groove, and a limiting plate 221 is slidably installed in the second limiting groove. The limiting plate 221 slides in the second limiting groove to limit the sliding of the sliding seat 22, thereby preventing the sliding seat 22 from extending out of or leaving the installation groove.

[0030] In daily use, it is not necessary to connect with multiple devices. Therefore, the telescopic seat 2 does not need to slide out to expose the output interface 21 of the side wall and the front and rear surfaces. In order to fix the position of the telescopic seat 2, a card block 3 is slidably installed on the upper end of the box body 1. Specifically, a dial plate 32 is fixedly connected to one end of the card block 3. Both sides of the slot of the installation slot are provided with a first slide groove. The dial plate 32 is slidably installed in the first slide groove. The card block 3 can be driven to slide by moving the dial plate 32 with a finger. Figure 6As shown, a slot 31 is provided at the upper edge of the telescopic seat 2 and the upper edge of the sliding seat 22. After the telescopic seat 2 extends out of the installation slot, the dial plate 32 is moved to drive the card block 3 to engage in the card slot 31 of the sliding seat 22, thereby fixing the extended state of the telescopic seat 2. Touch the upper edge of the telescopic seat 2 with your hand, press down the telescopic seat 2, drive the telescopic seat 2 and the sliding seat 22 to retract into the installation slot, and move the dial plate 32 to drive the card block 3 to engage in the card slot 31 of the telescopic seat 2, thereby fixing the telescopic seat 2 to retract into the installation slot.

[0031] When the telescopic seat 2 is pressed down and the dial plate 32 is toggled, since one hand is pressing the telescopic seat 2, the dial plate 32 can only be toggled one by one by the other hand. If one of the blocks 3 on both sides of the telescopic seat 2 is not engaged in the slot 31 or is not engaged in place, the telescopic seat 2 and the sliding seat 22 are prone to tilt in the installation slot. In order to synchronously move the blocks 3 and ensure that the blocks 3 can be accurately engaged in the slot 31, the lower end of the dial plate 32 is fixedly connected with a push plate 321, and the box body 1 is provided with a second elastic member 33 for applying elastic force to the push plate 321. Specifically, a second slide groove is provided at the bottom of the first slide groove, the push plate 321 is slidably installed in the second slide groove, the second elastic member 33 is installed in the second slide groove, the second elastic member 33 is set as a spring, and one end of the second elastic member 33 is fixedly connected to the end surface of the push plate 321, and the second elastic member 33 applies an elastic force toward the installation slot to the push plate 321.

[0032] like Figure 5 As shown, the end face of the card block 3 is set as an inclined surface. When the telescopic seat 2 needs to be retracted, the telescopic seat 2 is pressed down, and the lower edge of the telescopic seat 2 contacts the inclined surface of the card block 3, and a thrust is applied to one end of the card block 3 to drive the card block 3 to slide in the direction away from the installation groove. Even if the card block 3 is out of the card slot 31 of the sliding seat 22, after the upper end face of the telescopic seat 2 is flush with the upper end face of the box body 1, the second elastic member 33 applies an elastic force to the push plate 321 to drive the dial plate 32 and the card block 3 to slide in the direction of the installation groove, so that the card block 3 is engaged in the card slot 31 of the telescopic seat 2, and the card block 3 is engaged at the upper end edge of the telescopic seat 2 to prevent the telescopic seat 2 from extending out of the notch of the installation groove.

[0033] When the telescopic seat 2 needs to be popped out from the notch of the mounting groove, two fingers respectively push the two push plates 32 of the mounting groove to drive the card block 3 to disengage the card slot 31 of the telescopic seat 2. The telescopic seat 2 can be popped up upward under the elastic force of the first elastic member 4. Due to the limit plate 221 limiting the sliding seat 22, the card slot 31 of the sliding seat 22 is horizontally aligned with the card block 3. At this time, after releasing the push plate 32, the second elastic member 33 applies elastic force to the push plate 321, driving the push plate 32 and the card block 3 to slide in the direction of the mounting groove, so that the card block 3 is engaged in the card slot 31 of the sliding seat 22, thereby fixing the extended telescopic seat 2.

[0034] When the telescopic seat 2 is retracted into the installation slot, the clamping block 3 prevents the telescopic seat 2 from popping out, but due to the elastic force of the first elastic member 4, the telescopic seat 2 applies an upward thrust to the clamping block 3. In order to prevent the dial plate 32 from being separated from the first slide slot, the side of the dial plate 32 is fixedly connected to the limiting strip 322. Specifically, the side wall of the first slide slot is provided with a first limiting slot, and the limiting strip 322 is slidably installed in the first limiting slot. By sliding the limiting strip 322 in the first limiting slot, the dial plate 32 can be limited to prevent the dial plate 32 from being separated from the first slide slot.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
