Detailed Description
The invention will be further described with reference to specific examples, but the scope of the invention is not limited thereto:
example (b): as shown in fig. 1, 2 and 3, a battery box fixing and locking device for heavy truck battery replacement comprises a battery base 1, a side-inserted type locking pin 2, a guide block 3, a limiting pin 4, a limiting block 5, a battery box frame 6 and a locking plate 7. Guide block 3 welded fastening is on battery base 1, and the formula locking pin 2 can only horizontal linear motion in guide block 3 is inserted to the side, and spacing pin 4 passes through the fix with screw on battery base 1, and only jam plate 7 and stopper 5 welded fastening are on battery box frame 6.
Install the side on the battery base and insert formula locking pin, have on the battery box frame with the locking plate that the side inserted formula locking pin position suited, the side is inserted formula locking pin and is contacted with the locking plate to restriction vertical direction displacement and the rotational degree of freedom between battery base and the battery box frame. The battery box frame is provided with a limiting pin, the limiting block is matched with the limiting pin in position, and the limiting pin is in contact with the limiting block so as to limit the horizontal displacement and the rotational degree of freedom between the battery base and the battery box frame.
The side-inserted type locking pin is inserted above the locking plate to form connection between the side-inserted type locking pin and the locking plate.
The limiting block is provided with a positioning surface consistent with the overall dimension of the limiting pin, and the limiting pin is inserted in the limiting areas formed by the limiting block.
The main part of battery base is a rectangular welding frame body, and rectangular welding frame body four corners inboard has arranged respectively the symmetrical arrangement spacing pin, has arranged the formula locking pin of inserting of side on the frame that long limit and strengthening rib formed respectively.
The main part of battery box frame is a rectangular welded frame body, and the inside formation space of rectangular welded frame body is the installation space of battery box, and rectangular welded frame body's bottom four corners inboard has symmetrical arrangement respectively the stopper, the bottom long limit of rectangular welded frame body in the middle of and the bottom middle strengthening rib arrange the lock plate respectively.
