[0001] The utility model relates to the field of battery packs, in particular to a battery pack with a USB for a flashlight. Background Art

[0002] A Chinese patent with publication number CN210984867U discloses a battery pack, comprising two outer shells that can be interlocked to form a cylinder, one or more batteries installed in the outer shell, and an output port for the battery pack to charge other motor equipment and an input port for charging the battery pack are also provided on the outer shell.

[0003] When installing batteries in the battery pack of the above structure, it is necessary to first separate the two outer shells, then install the batteries into one outer shell, and finally snap the two outer shells together. Batteries are consumables, and the amount of power stored in the batteries will gradually decrease after long-term use. At this time, the batteries in the outer shells need to be replaced. Because the two outer shells are fixed to each other by snapping, when opening the outer shells, it is necessary to squeeze one outer shell hard to release the snapping with the other outer shell. Only then can the two outer shells be separated to replace the batteries inside, which makes it more laborious to replace the batteries in the outer shells. Utility Model Content

[0004] The utility model aims at the disadvantage that the two shells in the prior art are fixed to each other by snapping together. Therefore, when opening the shells, one shell needs to be squeezed hard to release the snapping with the other shell. Only then can the two shells be separated to replace the batteries inside them, which leads to the disadvantage that it is more laborious to replace the batteries in the shells. The utility model provides a battery pack with USB for flashlights, which is convenient and labor-saving to replace the internal batteries.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A battery pack with USB for a flashlight, comprising a barrel with an opening at one end for loading batteries therein, a cover provided at the open end of the barrel for closing the open end of the barrel after being partially inserted therein, a limiting component provided between the cover and the barrel for limiting the cover when the cover is mounted to the open end of the barrel, the limiting component comprising a receiving groove provided on the inner wall of the barrel near the open end, a limiting groove provided on the outer wall of the cover for facing the receiving groove after being partially inserted into the open end of the barrel, and a telescopic block provided in the receiving groove for telescoping and being partially inserted into the limiting groove after being extended, and a telescopic component for driving the telescopic block to telescope is provided between the telescopic block and the receiving groove.

[0007] By adopting the above scheme, the telescopic block can be partially inserted into the limiting groove on the cover when the cover is partially inserted into the cylinder, thereby reducing the probability of the cover falling out of the cylinder; after the battery is loaded into the cylinder, the cover can be inserted into the open end of the cylinder; during the insertion of the cover, the telescopic component can be used to drive the telescopic block to retract into the storage groove; when the limiting groove is directly opposite to the storage groove, the telescopic component can be used to drive the telescopic block to partially extend out of the storage groove and insert into the limiting groove, thereby limiting the cover; the cover is limited by the extension and contraction of the limiting block, making the assembly and disassembly of the cover more convenient and labor-saving, thereby facilitating people to replace the batteries in the battery pack with ease.

[0008] Preferably, the telescopic component includes a retractable component arranged on the telescopic block to drive the telescopic block to retract into the receiving groove when the cover is partially inserted into the interior of the cylinder, a rebound component arranged in the receiving groove to drive the telescopic block to partially extend out of the receiving groove, and an unlocking component to release the limit of the cover by the limiting component when the cover needs to be removed from the cylinder.

[0009] Preferably, the retractable component includes an introduction slope provided at one end of the telescopic block away from the bottom of the storage groove, and the introduction slope is inclined and narrowed from the end away from the opening of the cylinder to the end close to the opening of the cylinder.

[0010] By adopting the above scheme, the introduction slope can be set to drive the telescopic block to gradually retract into the receiving groove when the cover is partially inserted into the cylinder, so that the cover can be smoothly inserted into the cylinder to close the opening of the cylinder.

[0011] Preferably, the resilient component comprises a spring arranged between the bottom of the storage groove and the bottom of the telescopic block.

[0012] By adopting the above scheme, the spring can make the telescopic block partially extend out of the storage slot under normal conditions, and can also drive the telescopic block to return to partially extend out of the storage slot after the telescopic block is retracted into the storage slot.

The pulling block extends out of the cylinder after passing through the through groove, and an anti-falling component is arranged on the pulling block extending out of the cylinder to prevent the telescopic block in the storage groove from falling out of the storage groove.

[0014] By adopting the above scheme, when the battery in the cylinder needs to be taken out of the cylinder, the pulling plate can drive the telescopic block inserted into the limiting groove on the cover to escape from the limiting groove and retract into the receiving groove. At this time, the cover can be removed from the cylinder, and the anti-detachment component can prevent the telescopic block in the receiving groove from escaping from the receiving groove.

[0015] Preferably, the anti-slip component includes a socket provided on the surface of the pulling block extending out of the cylinder and a conical plug pin which can be partially inserted into the socket.

When the pin is set to be conical, the pin can be squeezed with the inner wall of the socket when inserted into the socket, thereby reducing the probability of the pin falling out of the socket.

[0017] Preferably, a guide component for guiding the cover when the cover is inserted is provided on the outer wall of the cover and the inner wall of the cylinder near the opening.

[0018] Preferably, the guide component comprises a guide plate vertically arranged on the inner wall of the cylinder near the opening and a guide groove arranged on the outer wall of the cover for the guide plate to slide into when the cover is inserted into the cylinder.

[0019] By adopting the above scheme, the guide plate arranged on the inner wall of the cylinder can guide the cover when the cover is partially inserted into the cylinder, so that the telescopic block arranged inside the cylinder can be smoothly inserted into the limiting groove on the cover to limit the cover.

[0020] Preferably, the limiting components are symmetrically arranged on both sides of the inner wall of the cylinder and the outer wall of the cover.

[0021] By adopting the above solution, symmetrically arranging the limiting components on both sides of the inner wall of the cylinder and the outer wall of the cover can further reduce the probability of the cover partially inserted into the cylinder falling out of the cylinder, thereby reducing the probability of the battery falling out of the cylinder.

[0022] Preferably, the cover is also provided with a charging port for charging the battery pack and an output port for the battery pack to charge other electronic devices.

[0023] By adopting the above scheme, people can charge the battery in the barrel through the provided charging port, and when other electronic devices need to be charged, the power in the battery pack can be charged into the electronic devices through the data cable through the output port.

[0024] The utility model has significant technical effects due to the adoption of the above technical scheme: the telescopic block can be partially inserted into the limiting groove on the cover when the cover is partially inserted into the inside of the cylinder, thereby reducing the probability of the cover falling out of the cylinder; after the battery is loaded into the cylinder, the cover can be inserted into the open end of the cylinder; during the insertion of the cover, the telescopic component can be used to drive the telescopic block to retract into the storage groove; when the limiting groove is directly opposite to the storage groove, the telescopic component can be used to drive the telescopic block to partially extend out of the storage groove and insert into the limiting groove, thereby limiting the cover; the cover is limited by the extension and contraction of the limiting block, making the assembly and disassembly of the cover more convenient and labor-saving, thereby facilitating people to replace the batteries in the battery pack with less effort.
