Charging combination and anti-off wall-mounted shell thereof

Abstract

The invention discloses a charging combination and an anti-off wall-mounted shell thereof. The charging combination mainly comprises a charger, and a battery pack which can be plugged into and pulled out of the charger along a third direction. The charger comprises an anti-off wall-mounted shell and circuit elements therein. The anti-off wall-mounted shell comprises a shell body which has more than one anti-off nail hanging hole. Each anti-off nail hanging hole at least comprises an inserting hole in which a nail head can be inserted and a limiting hole which can stop the nail head from passing through and only allow a nail body to pass through, a communicating gap is arranged between the inserting hole and the limiting hole, and the limiting hole consists of a linear track and an arc track. The beneficial effect lies in that through special design of the anti-off nail hanging holes, a wall nail can exit to the inserting holes only when the wall nail moves according to a preset exit trajectory, so that the possibility of fall-off is greatly reduced, and the safety of the whole charging combination is ensured.

Description

technical field [0001] The invention relates to a charging combination and its casing, in particular to a charging combination and its casing capable of preventing the wall hanging from falling off. Background technique [0002] The chargers for high-power electric tools or one-to-many chargers are relatively large in size, and the input terminals are mostly AC strong power. In order to avoid the chargers taking up space or to avoid danger caused by children's touch, users generally The charger will be hung on a higher wall. [0003] In order to achieve the purpose of hanging, the shell of the existing charger is generally provided with two or more than two same wall-mounting holes. parallel, and the direction is set along the direction of gravity, so that when the charger is hung on the wall, it is not easy to fall off due to its own gravity hanging on the wall nail. [0004] But for the battery pack in the charging combination, in order to rely on gravity to keep the ba...

Problems solved by technology

[0004] But for the battery pack in the charging combination, in order to rely on gravity to keep the battery pack plugged into the charger, the plugging direction of the battery pack always has a component that coincides with the direction of gravity, so when the battery pack is pulled out, it will always Because the friction drives the charger to move relative to the wall stud to the position where the two are separated, it is easy to take the charger away from the wall stud, causing the charger to fall and hurt the user, or break the charger, posing a safety hazard
