The outer shell of the charging plug 7 is a rectangular shell, of which the two sides are respectively equipped with a type-c interface and an interface for an Apple mobile phone (Lightning interface). The one-to-two wires of the charging plug 7 are installed in the outer shell of the charging plug 7. The charger base 1 is connected to electricity. The charger base 1 is equipped with a current detection resistor and a power management chip. The current detection resistor detects the magnitude of the output current in real time. The detected current value is fed back to the control chip. The chip adjusts the output current of the charger according to the preset algorithm and current threshold, thereby achieving the effect of adaptive current regulation.

[0052] The protection seat 5 is fixed on the top of the protection cover 4, and the protection cover 4 is attached to the inclined plate 3. The two ends of the protection seat 5 are respectively fixedly connected with the thread ring 29 and the slider 30.

[0054] There are three polygonal grooves 40, namely a triangular groove, a quadrilateral groove and a pentagonal groove. A positioning rod 34 is movably sleeved in each side groove 31. The proximal ends of the two positioning rods 34 are rotatably connected to a pair of rotating frames 39. The proximal ends of the two rotating frames 39 are rotatably connected to a disc 35 with a connecting piece. The middle part of the disc 35 is provided with a middle groove 37.

[0056] There are three polygonal parts 23 , namely a triangular part, a rectangular part and a pentagonal part. The shapes of the three polygonal parts 23 correspond to the shapes of the three polygonal grooves 40 .

[0057] A rectangular cover 21 is fixedly connected to the slider 30, a limit plate 28 is fixedly connected to the rectangular cover 21, a thick rod 26 is fixedly connected to the inner wall of the rectangular cover 21, a thin rod 27 is fixedly connected to the end of the thick rod 26, the thin rod 27 is movably sleeved in the middle groove 37, the thin rod 27 is fixedly connected to the fixed rod 38, a spring 2 36 is fixedly connected between the disc 35 and the inner wall of the rectangular cover 21, and the spring 2 36 is sleeved on the thin rod 27. When the user inserts the mobile phone to start charging and leans the mobile phone against the inclined plate 3, the protective cover 4 can be moved horizontally along the card slot 20, so that the slider 30 can slide down along the strip groove 19 until the inner top surface of the protective cover 4 is against the top of the mobile phone. At this time, the operator can rotate the threaded sleeve 22 to disengage the threaded sleeve 22. The threaded ring 29 is released, so that the insertion rod 24 is pulled out of the rod groove 32. At this time, the disc 35 loses the restriction of the top rod 25, and the disc 35 is pushed to move under the elastic force of the spring 2 36, and then the two positioning rods 34 are pushed to separate through the rotating frame 39. The two positioning rods 34 are exposed in the side grooves 31 and inserted into the positioning holes at the corresponding positions, thereby achieving the effect of fixing the position of the protective cover 4. The protective cover 4 cooperates with the charging plug 7 to clamp the mobile phone in the middle. Without removing the protective cover 4, the mobile phone cannot be taken away, and the pulled out insertion rod 24 can be taken away and kept by the operator. As a special key, the mobile phone can be placed on the device for charging without worrying about losing it, which improves the convenience of the user. The operator can do other things without watching the mobile phone.

[0058] Working principle:

[0059] The side walls of the three charging slots 6 of the charger base 1 are all equipped with power cords. The power cords in the three charging slots 6 are connected to the charging plugs 7 in the three charging slots 6 respectively. The outer shell of the charging plug 7 is a rectangular shell, and the two sides are respectively equipped with a type-c interface and an interface for Apple mobile phones (Lightning interface). The one-to-two wires of the charging plug 7 are installed in the outer shell of the charging plug 7. The charger base 1 is connected to electricity. The charger base 1 has built-in current detection resistors and power management chips. The current detection resistor detects the output current in real time. The detected current value is fed back to the control chip, and the chip adjusts the output current of the charger according to the preset algorithm and current threshold, thereby achieving the effect of adaptive current regulation;

[0060] The user who needs to charge the mobile phone should first turn the charging plug 7 to make the appropriate interface face upward. The existence of the two limit blocks 18 makes the charging plug 7 only deflect by ninety degrees at most. No matter whether the type-c interface or the light interface faces upward, there is a limit block 18 against the deflection seat 9. The two limit blocks 18 can also be used as counterweights to prevent the deflected charging plug 7 from shaking easily and keep the correct interface facing upward. The operator can quickly adjust the required interface to the upward state by turning the charging plug 7, which is quick to operate.

[0061] The operator inserts the mobile phone downward so that the charging port of the mobile phone is plugged into the interface of the charging plug 7, and then the operator continues to press the mobile phone downward, so that the mobile phone can push the deflection seat 9 downward, thereby driving the shaft 10 to slide down along the vertical groove 12 until the switching part 17 slides down into the circular groove 11. The shape of the switching part 17 is shown in FIG. Figure 2 At this time, the switching part 17 loses the restriction of the vertical groove 12 and can rotate in the circular groove 11. At this time, the operator can deflect the mobile phone so that the mobile phone leans against the inclined plate 3, and use the inclined plate 3 and the charging plug 7 to support the mobile phone together, so as to avoid the charging plug 7 being subjected to concentrated force when the charger base 1 shakes and thus affecting its service life;

[0062] During the descent of the mobile phone, the spring 14 is pulled, and during the deflection of the mobile phone, the deflection rod 13 further pulls the spring 14, so that after the mobile phone is pulled out, the switching part 17 is first reset under the elastic force of the spring 14, and then the switching part 17 slides up along the vertical groove 12, so that the charging plug 7 is automatically reset after the mobile phone is pulled out, and the next user can use it directly without manual intervention, thereby improving convenience and efficiency;

[0063] After the user inserts the mobile phone to start charging and places the mobile phone against the inclined plate 3, the protective cover 4 can be moved horizontally along the card slot 20, so that the slider 30 can slide down along the strip groove 19 until the top surface of the protective cover 4 is against the top of the mobile phone. At this time, the operator can rotate the threaded sleeve 22 to disengage the threaded sleeve 22 from the threaded ring 29, so that the insertion rod 24 is pulled out of the rod groove 32. At this time, the round piece 35 loses the restriction of the top rod 25, and the round piece 35 is pushed to move under the elastic force of the spring 2 36, and then the two positioning rods 34 are pushed to separate through the rotating frame 39. The two positioning rods 34 are exposed in the side grooves 31 and inserted into the positioning holes at the corresponding positions to achieve the effect of fixing the position of the protective cover 4. The protective cover 4 cooperates with the charging plug 7 to clamp the mobile phone in the middle. Without removing the protective cover 4, the mobile phone cannot be taken away, and the pulled-out insertion rod 24 can be taken away and kept by the operator. As a special key, the mobile phone can be placed on the device for charging without worrying about losing it, which improves the convenience of the user. The operator can do other things without watching the mobile phone.

[0064] The three charging slots 6 on the device can charge three mobile phones, and the three mobile phones are respectively protected from loss by three protective covers 4. The polygonal grooves 40 on the three protective seats 5 on the device are of different shapes, and the corresponding three plug rods 24 are respectively fixed with polygonal pieces 23 of corresponding shapes, so that the three plug rods 24 cannot be shared, further improving safety;

[0065] When the mobile phone needs to be taken away, the insertion rod 24 is inserted and the threaded sleeve 22 and the threaded ring 29 are connected. The push rod 25 squeezes the disc 35, and the positioning rod 34 can be retracted, so that the protective cover 4 can be moved up, and the restriction protection of the mobile phone is released, and the operator can conveniently take the mobile phone;

[0066] The device completely adopts a mechanical linkage method to protect and place the mobile phone while charging. The operation is simple and easy to understand. It has outstanding applicability for older people (people who are not proficient in mobile phone scanning, registration, etc.) and situations where the mobile phone has run out of power and cannot be turned on to scan the code, etc. The charger base 1 only needs to be responsible for charging the mobile phone. Compared with the common scanning code unlocking, small program registration charging and other methods, it has outstanding convenience;

[0067] When not in use, the three charging slots 6 of the device can be covered by three protective covers 4 to prevent dust accumulation in the charging slots 6. The management staff can also reserve multiple plug rods 24 so that the user can unlock the phone and verify when the plug rod 24 is lost. The cost of replacing accessories is low.

[0068] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
