[0026] Embodiment one
[0027] The utility model embodiment provides multi-interface mobile power supply.
[0028] Please refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4, including mobile power supply body 1, mobile power supply body 1 is also called power bank, travel charger and the like, is a kind of portable equipment with power supply and charging function in one, aims at providing additional power support for various mobile electronic devices to solve the problem of insufficient power of these devices when being outdoors or unable to connect to mains power, mobile power supply body 1 side is provided with several charging interfaces 2, mobile power supply body 1 side is fixed with fixed frame 3;Fixed frame 3 middle part is provided with through slot 4, both sides of fixed frame 3 are provided with sliding slot 5, the inner wall of through slot 4 is provided with connecting structure, the connecting structure includes two closed frames 6, two closed frames 6 are fixed with sliding block 7 on the side away from each other, two sliding blocks 7 are slidably connected with stabilizing rod 8 in the middle part, two sliding blocks 7 are fixed with first spring 9 on the side away from each other.
[0029] Please refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4 , it is worth noting that the two first springs 9 are fixed on the side away from each other of the two sliding blocks 7, the two first springs 9 are fixed on the inner wall of the side away from each other of the two sliding slots 5, the outer surfaces of the two sliding blocks 7 are slidably connected to the inner walls of the two sliding slots 5, the two ends of the two stabilizing rods 8 are fixed in the middle part of the two sliding slots 5, the middle parts of the two sliding blocks 7 are slidably connected to the outer surfaces of the two stabilizing rods 8, the two sliding blocks 7 are fixed on the middle part of the two closed frames 6, the outer surfaces of the two closed frames 6 are slidably connected to the inner walls of the through slot 4, the two closed frames 6 are oppositely arranged, and each closed frame 6 is provided with a U-shaped vertical section.
[0030] The utility model discloses in use: in the use process, user manually presses two closed frames 6, promotes them to overcome resistance and slide reversely in the path defined in through slot 4. With the reverse sliding of closed frame 6, two sliding blocks 7 fixed on the side away from each other are also started, and reversely slide and gradually move away from each other accurately under the double limiting guide of two sliding slots 5 and stabilizing rod 8. In this process, two sliding blocks 7 exert tension on the first spring 9 fixed on the side away from each other, so that the first spring 9 is gradually stretched and stores elastic potential energy. When two closed frames 6 slide to specific position, the shielding of several charging interfaces 2 is completely removed, at this moment, charging operation can be smoothly carried out, and the power supplement demand of digital device is met;
[0031] When the charging task is completed, the two first springs 9, which have been stretched, start to release the elastic force due to the internal stored elastic potential energy, and generate a contraction trend. Under the cooperative limiting action of the two sliding grooves 5 and the two stabilizing rods 8, the two sliding blocks 7 stably approach each other under the pulling of the spring elastic force. The two closed frames 6, which are fixedly connected with the sliding blocks 7 and oppositely arranged, gradually approach and finally close under the constraint of the through grooves 4, tightly cover the charging interface 2, form an effective protective barrier, realize the effect of closed covering, successfully isolate the contact between the dust and impurities in the outside world and the charging interface 2, fundamentally eliminate the hidden dangers of various charging faults caused by the accumulation of dust and impurities, and further improve the use effect of the multi-interface mobile power supply.
[0032] Embodiment two
[0033] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , on the basis of embodiment one, the function of stable plugging is increased;
[0034] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , it is worth noting that a plurality of recesses 10 are arranged in the middle of the two closed frames 6, a stable groove 11 is arranged on one side of each recess 10, a sliding plate 12 is slidably connected to the inner wall of each stable groove 11, a pressing frame 13 is fixed to one end of each sliding plate 12, a second spring 14 is fixed to the other end of each sliding plate 12, the outer surface of each sliding plate 12 is slidably connected to the inner wall of each stable groove 11, the middle of each sliding plate 12 is fixed to one end of each pressing frame 13, the outer surface of each pressing frame 13 is slidably connected to the inner wall of each recess 10, the plurality of pressing frames 13 are symmetrically distributed with the plurality of charging interfaces 2, one end of each second spring 14 is fixed to one end of each sliding plate 12, and the other end of each second spring 14 is fixed to the inner wall of each stable groove 11.
[0035] In actual use, the user applies manual pressure to the two closed frames 6, so that they can break through the resistance and slide reversely along the accurate track defined by the through grooves 4, thereby leaving space for subsequent charging operation, so that the charging plug of the connecting line can be smoothly inserted into the charging interface 2;
[0036] After the plug insertion action is completed, the user releases the pressure applied on the closure frame 6, and the two first springs 9, which have been stretched before, start to release the elastic force due to the internal stored elastic potential energy, and generate a contraction trend, which promotes the two closure frames 6 to gradually approach each other. In this process, the two pressing frames 13 arranged on the inner wall of the groove 10 of the closure frame 6 will contact the connection line plug and generate a pressing action on the connection line plug when the closure frame 6 moves to approach. Due to the reaction force of the plug, the two pressing frames 13 will move away from each other, and further drive the sliding plate 12 fixed at the away end to slide in the strict limitation of the inner wall of the stable groove 11. In this process, the sliding plate 12 exerts pressure on the second spring 14 connected thereto, which promotes the second spring 14 to start to compress and generate a corresponding elastic force. With the continuous pressing action, the elastic force generated by the second spring 14 will continuously increase until the second spring 14 is compressed to its limit state. In this process, the pressing frame 13 will tightly press the inserted connection line plug in the charging interface 2 with the aid of the elastic force of the second spring 14, to form a stable connection structure. The effect of stable plug-in is achieved, which effectively prevents the plug-in charging plug from loosening or even falling off due to various external force factors in the use process, and further achieves the effect of improving the use stability of the multi-interface mobile power supply.
