Detailed implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] As Figure 1-8 shown, the present invention provides a portable lithium battery, which is mainly used for power supply and has the characteristics of being convenient to carry outdoors. Its specific structure mainly consists of two parts: a battery body 1 and a movable plate 2. One end of the bottom of the battery body 1 can be assembled on the surface of the movable plate 2 to form a detachable structure. When in use, the battery body 1 can be used independently or in combination with the movable plate 2.

[0028] When the battery body 1 is connected to the movable plate 2, a battery placement slot 13 for placing and fixing the battery body 1 is provided on the surface of the movable plate 2. After the battery body 1 is placed, the movable plate 2 is connected to the lower part of the battery body 1. In order to increase the sealing performance and fixing of the battery body 1 in the battery placement slot 13, a sealing layer 14 that is sealed with the battery body 1 is provided on the inner wall of the lithium battery placement slot 13. The sealing layer 14 can be a silicone layer or a soft plastic layer. In addition, a number of locking pieces 15 are added outside the movable plate 2 for locking and fixing. The locking pieces 15 are inserted from the outside of the movable plate 2, pass through the sealing layer 14 and are inserted into the inside of the battery body 1 for locking.

[0029] A handle 5 for convenient hand - carrying is added to the top of the battery body 1, and the U - shaped handle 5 can also be hidden in the U - shaped groove 3 on the surface. When connecting, at the bottom of both sides of the U - shaped groove 3, there are first connectors 4 arranged to pop out. At both ends of the handle 5, there are first notches 16 that are attached to both sides of the first connectors 4 and can be flipped. A first movable shaft 17 connected to the corresponding first connector 4 is inserted through the handle 5. The first movable shaft 17 is inserted from one side of the handle 5, passes through the first connector 4 in the first notch 16 to the other side of the handle 5. At this time, the handle 5 can be freely flipped under the connection of the first movable shaft 17. In order to better hide and avoid jamming during flipping, one end of the first connector 4 that pops out upward is in a semi - circular structure and is arranged in the U - shaped groove 3.

[0030] Four pulleys 12 for convenient pushing on the ground are also added to the bottom of the moving plate 2. Users can choose to carry it in the way of hand - carrying or in the way of pushing on the ground. Users can flip down and fix the four pulleys 12 hidden inside the moving plate 2 and directly use them to push and drive the battery body 1 to move on the ground. At the bottom of the moving plate 2, two long slots 6 are arranged in a front - and - rear distribution. The four pulleys 12 are assembled at both ends of the two long slots 6, that is, at the four - corner positions at the bottom of the moving plate 2. When connecting, at the bottom of both ends of the long slot 6, there are second connectors 7 arranged to pop out. At the top of the wheel seat 8 connecting the pulley 12, there are second notches 18 that are attached to both sides of the second connectors 7 and can be flipped. Each wheel seat 8 is inserted with a second movable shaft 19 connected to the corresponding second connector 7. The second movable shaft 19 is inserted from one side of the wheel seat 8, passes through the second connector 7 in the second notch 18 to the other side of the wheel seat 8. At this time, the wheel seat 8 can be freely flipped under the connection of the second movable shaft 19. Similarly, in order to better hide and avoid jamming during flipping, one end of the second connector 7 that pops out is in a semi - circular structure and is arranged in the long slot 6.

[0031] When pushing the battery body 1 on the ground, at this time the pulley 12 moves downward as the wheel seat 8 flips. In order to better fix the structure of the wheel seat 8 and avoid rotation during pushing, a movable block 10 for snap - connection and fixation is added between the two wheel seats 8. Structurally, when the pulley 12 moves downward, on the opposite sides of the wheel seats 8 arranged at both ends of the same long slot 6, there are raised clamping bars 9. At the bottom of the long slot 6, there is a movable block 10 that is pulled out toward the opening to contact the wheel seats 8 at both ends. On both sides of the movable block 10, there are clamping slots 11 fixed to the clamping bars 9. In order to better manually control the movable block 10, at the bottom of the long slot 6, there is a movable - block placement groove 20 for accommodating the movable block 10. Inside the movable - block placement groove 20, there is a telescopic rod 21 for connecting and adjusting the position of the movable block 10. At the same time, on the surface of the movable block 10, there is a hand - grip position 22 for convenient hand - grasping. When in use, after hiding the pulleys 12 at the bottom, the position of the battery body 1 can be fixed and there will be no sliding during use.

[0032] Compared with the traditional technology, a handle 5 for convenient hand carrying is added to the top of the battery body 1 in this technical solution. At the same time, a detachable moving plate 2 at the bottom is provided with pulleys 12 for convenient pushing on the ground and carrying. Through two different carrying methods, it is convenient for users to use in different environments and has better flexibility.

[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model, and any reference signs in the claims should not be regarded as limiting the claims involved.
