Detailed Description

Example one

The dust collection box locking device matched with the electric hammer has a structure shown in fig. 1, 2 and 3, and the middle part of a lath-shaped locking rod 1 is hinged and fixed on a plug socket 4 of a box body 3 through a hinge pin 2. One end of the locking rod 1 far away from the tool body is connected with an unlocking button 5 arranged on the box body 3 through an inclined surface 1-1, and one end of the locking rod 1 near the tool body is provided with a tapered end 7 which tends to be clamped into the tool body 6. Specifically, the unlocking knob 5 and the insertion hole 3-1 of the case 3 constitute a moving pair, and the inner end thereof is engaged with the inclined surface 1-1 of the locking lever 1 through the wedge surface 5-1, and the inner end thereof abuts against the return spring 8, thereby having a pressed unlocking position and a return locking position. The inserting seat 4 and the inserting groove 6-2 at the corresponding position of the tool main body 6 form a moving pair through the inserting ribs 4-2 at the two sides of the inserting end. One end of the locking rod 1 adjacent to the tool body is in a front extending fork shape clamped on a step surface 7-1 of a locking head 7, the upper end of the locking head 7 passes through a through hole 4-1 of an insertion end of the inserting seat 4 and then is clamped into a clamping concave 6-1 at a corresponding position of the tool body 6, and the lower end of the locking head 7 is abutted against a spring 9 arranged in the inserting seat 4, so that the locking head has a tendency of being clamped into the tool body 6.

When the unlocking button 5 is pressed into the insertion hole 3-1 of the box body 3 to be positioned at the unlocking position by overcoming the acting force of the reset spring 8, the wedge-shaped surface 5-1 at the inner end acts on the inclined surface to pry the locking rod 1, the stepped surface 7-1 is pressed downwards through the fork opening of the locking rod, the locking head 7 is pried to be clamped into the clamping recess 1-6 of the tool body 6 to be released, and as shown in fig. 2, the plug socket 4 can be smoothly pulled out of the tool body 6 at the moment, so that the box body 3 is separated from the tool body 6. When the unlocking button 5 is released, the reset spring 8 makes it in the reset locking position, as shown in fig. 3, at this time, the lock head 7 will enter into the locking position of the locking recess 6-1 of the tool body 6, so that the box body 3 and the tool body 6 are reliably combined with each other.

The separation structure of the unlocking button and the locking rod not only effectively avoids the tripping caused by external disturbance, ensures reliable locking, realizes one-way locking, but also has small structural design limitation, and the distance between the unlocking button and the lock head can be set according to the ergonomic principle, so that the operation is more handy.

In addition to the above embodiments, the present invention may have other embodiments. For example, rather than the end of the locking lever adjacent the tool body being in the form of a forwardly extending prong that snaps over the stepped surface of the lock cylinder, the reverse concept is contemplated where the lock cylinder has a downwardly opening prong, the end of the locking lever adjacent the tool body is in the form of a plug that extends into the prong of the lock cylinder, and so on. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
