Technical Field

[0001] The utility model relates to the technical field of mobile power supplies, in particular to a cylindrical mobile power supply. Background Art

[0002] Currently, mobile power supplies are divided into two types. The first type comes with a built-in data cable and can directly charge a mobile phone, but the data cable cannot be detached. The second type requires a user to prepare their own data cable, and the data cable can be detached and replaced. For the second type of mobile power supply, the data cable is inconvenient to carry, often resulting in the situation of forgetting to bring it, leaving it behind, or losing it.

[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] A cylindrical mobile power supply, comprising

[0028] A metal cylinder 1, which is provided with a charging port 11 and a switch 12 at its front end;

[0029] A battery 2, which is arranged inside the metal cylinder 1 and is electrically connected to the charging port 11 and the switch 12;

[0030] A movable cylinder 3, which is sleeved with the metal cylinder 1 and slides relative to the metal cylinder 1. An LED light source 5 electrically connected to the battery 2 is provided at the tail end of the movable cylinder 3;

[0031] A receiving cavity 30 is arranged inside the movable cylinder 3. When the movable cylinder 3 moves relative to the metal cylinder 1 to an extended position where the head and tail are connected, the receiving cavity 30 is exposed; when the movable cylinder 3 moves relative to the metal cylinder 1 to a retracted position where the tail ends of the two are connected, the receiving cavity 30 gives way to the battery 2.

[0032] The present utility model provides a cylindrical mobile power supply. When not in use, the data cable can be placed in the receiving cavity for easy carrying. When in need of use, take out the data cable and connect it to the charging port, and then the movable cylinder can be retracted, thereby reducing the volume and facilitating use. When the movable cylinder extends, it is convenient to hold, and by using the LED light source, it can be used as a flashlight.

[0033] Further, as a preferred implementation manner of this solution rather than a limitation, anti-slip grooves 13 are convexly arranged on the circumferential side of the metal cylinder 1 along its length direction. A buckle 31 is arranged on the movable cylinder 3, and the buckle 31 is embedded inside the anti-slip groove 13 to slide along the anti-slip groove 13. The outer side of the anti-slip groove protrudes, which can play an anti-slip role, and the inner side is recessed outward to cooperate with the buckle.

[0034] Further, as a preferred implementation manner of this solution rather than a limitation, separation bands 32 are arranged on both sides of the buckle 31 for elastically bending the buckle 31 into the receiving cavity 30. During the process of inserting the movable cylinder into the metal cylinder, the buckle is made to enter the anti-slip groove by elastic bending.

[0035] Further, as a preferred implementation manner of this solution rather than a limitation, a cover plate 4 is further included. An opening 33 communicating with the receiving cavity 30 is arranged on the movable cylinder 3, and the cover plate 4 is movably connected to the movable cylinder 3 to conduct or block the opening 33. Figure 2It is the state where the cover plate is closed. Figure 3 It is the state where the cover plate is open. After the cover plate is closed, it restricts the data cable from falling out.

[0036] Furthermore, as a preferred implementation manner of this solution rather than a limitation, a retaining ring 41 that abuts against the bottom of the movable cylinder body 3 is provided at the head end of the cover plate 4. When the movable cylinder body 3 retracts, it presses against the retaining ring 41 to drive the retaining ring 41 to retract synchronously.

[0037] Furthermore, as a preferred implementation manner of this solution rather than a limitation, a convex block 34 is provided on the movable cylinder body 3, and a groove 42 is provided on the cover plate 4. The convex block 34 and the groove 42 cooperate to drive the cover plate 4 to extend synchronously when the movable cylinder body 3 extends.

[0038] Furthermore, as a preferred implementation manner of this solution rather than a limitation, after the movable cylinder body 3 extends, after the groove 42 disengages from the convex block 34, the cover plate 4 can move relative to the movable cylinder body 3.

[0039] Furthermore, as a preferred implementation manner of this solution rather than a limitation, when the cover plate 4 covers the opening 33, a gap 35 is left between the cover plate 4 and the opening 33. It is convenient to observe whether there is a data cable in the storage cavity and to push open the cover plate.

[0040] Furthermore, as a preferred implementation manner of this solution rather than a limitation, it further includes a data cable for connecting the charging port 11 to the mobile phone, and the storage cavity is used to accommodate the data cable.

[0041] The above are only the preferred embodiments of this application and are not used to limit the scope of implementation of this application. All other embodiments with the same or similar principles and basic structures as this application are within the protection scope of this application.
