[0008] Preferably, the outer diameter of one end of the inner sleeve top is consistent with the outer diameter of one end of the outer sleeve top, and the second limiting block is attached to one side of the first limiting block through rotational cooperation.

[0009] The utility model provides a kind of intermediate sleeve for new energy battery box. With the following beneficial effects:

[0010] (1), the intermediate sleeve for new energy battery box, double-layer sleeve design is implemented the quick switching of bolt specification, when needing to adapt to bolt of different diameters, only need to simply disassemble inner sleeve, by inserting screwdriver into the clamping groove in the top of inner sleeve, it can make inner sleeve rotate, and then can disassemble inner sleeve, can directly use outer sleeve and bolt of larger diameter to connect.

[0011] (2), the intermediate sleeve for new energy battery box, by the threaded connection of one end of inner sleeve bottom and one end of outer sleeve top, then outer sleeve is aligned with battery box bolt hole, by rotating inner sleeve, when inner sleeve is screwed into outer sleeve, second limiting block will contact one side of first limiting block, then second limiting block can drive first limiting block to rotate, so that outer sleeve can be screwed into battery box bolt hole, so that the sleeve can be suitable for smaller bolt, thereby improve the applicability of the sleeve, the pre-tightening force applied by spring can ensure that outer sleeve is tightly attached in threaded hole, reduce the risk of loosening due to vibration or impact.

[0012] Thus, the problem of re-machining of threaded hole or replacement of parts due to change of bolt specification during equipment maintenance, modification or upgrading is solved, thereby reducing maintenance cost and time. ACCURACY OF DRAWINGS
