Detailed Description
One embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the invention is not limited to the embodiment.
As shown in fig. 1, 2, 3 and 4, a lithium battery convenient to install comprises a fixed shell 1 and a battery pack 2, wherein polygonal fixing holes 11 are formed in two sides of the shell 1; and may be generally square, regular pentagon or regular hexagon.
Two connecting lugs 22 are arranged on the battery pack 2 at intervals; each connecting lug 22 is respectively sleeved on a sliding rod 31 capable of doing linear reciprocating motion, and the shapes of the inner holes of the sliding rod 31 and the connecting lug 22 are consistent with the shape of the polygonal fixing hole 11; the polygonal fixing hole 11 and the sliding rod 31 have a square structure in section. The sliding rod 31 can be inserted into the polygonal fixing hole 11. And is to prevent the slide lever 31 from rotating in the polygonal fixing hole 11. With this rotation, the elastic stopper plate 21 can be swung within a limited angle. This oscillation facilitates the elastic limit plate 21 to limit and freely release the push plate 33 by bouncing and folding itself relative to the battery pack 2.
an elastic limit plate 21 which swings at a limited angle relative to the battery pack 2 is arranged on the battery pack 2 between the connecting lugs 22; the elastic limiting plate 21 is a hard plate with a trapezoidal structure and is hinged with the battery pack 2 through a torque spring.
An elastic limit plate 21 which swings at a limited angle relative to the battery pack 2 is arranged on the battery pack 2 between the connecting lugs 22;
the inner wall of the shell 1 is also provided with a first disassembly hole 12 and a first exchange hole 13 which is arranged on the inner wall of the shell opposite to the first disassembly hole 12; the caliber of the first exchange hole 13 is larger than the maximum cross section of the combination of the shift lever 4 and the cam 5. Furthermore, one end of the driving lever 4 is provided with a cylindrical chuck, and the chuck is clamped with the first dismounting hole 12.
A rotatable deflector rod 4 is detachably inserted between the first dismounting hole 12 and the first exchanging hole 13, and a cam 5 is fixed on the outer surface of the deflector rod 4; further, the cam 5 is coiled about half to three quarters of the circumference of the shift lever 4; further, the length of the shift lever 4 is greater than the width of the housing 1.
The axial length of the cam 5 is changed linearly, and the minimum length is smaller than the distance between the two push plates 33 when the convex positioning pin 32 contacts the connecting lug 22; the length is at the maximum equal to the distance between the two push plates 33 when the slide bar 31 is inserted into the polygonal fixing hole 11.
When the device is used, the elastic limit plate 21 is pressed downwards by the cam 5, then the sliding rod 31 is aligned with the polygonal fixing hole 11, then the shift lever 4 is plugged into the first exchange hole 13 to ensure that the cam 5 is just clamped between the two push plates 33, the cam 5 slowly pushes the push plates 33 by rotating the shift lever 4 until the sliding rod 31 is clamped in the polygonal fixing hole 11, and then the elastic limit plate 21 can be automatically bounced to realize fixing. And the battery pack 2 can be prevented from swinging with respect to the case 1 by the polygonal structure.
When the positioning pin is disassembled, the elastic limiting plate 21 is only required to be pressed down, the spring 34 automatically resets the protruding positioning pin 32, and the disassembly is completed.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
