Detailed Description
Example one
The present embodiment is a locking device for dust box, which is configured to be matched with an electric hammer, and has a structure as shown in fig. 1 to 4, wherein a middle portion of a locking rod 1 in the form of a strip is hinged to 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 an integrated lock head 7' which penetrates out of a through hole 3-2 of the box body 3 and tends to be clamped into the tool body 6.
The unlocking button 5 and the insertion hole 3-1 on the box body 3 form a moving pair, the inner end of the moving pair is connected with the inclined surface 1-1 of the locking rod 1 through the wedge-shaped surface 5-1, and the inner end of the moving pair abuts against the reset spring 8, so that the moving pair has a pressed unlocking position and a reset locking position.
The upper part of the box body 3 is provided with a hinged clamping strip 3-3 matched with a hinged clamping groove 6-3 of the corresponding part of the tool main body, a locking block 10 which forms a moving pair and is connected with the inner end of the unlocking button 5 is also arranged in the box body 3, the inner side of the locking block 10 is propped against a top spring 11 arranged on the box body 3, and the outer side of the locking block is provided with a flange 10-1 for clamping the locking rod 1, so that the locking rod 1 tends to approach and is locked. In addition, one end of the locking rod 1, far away from the tool body 6, abuts against a spring 9 'mounted on the box body 3, so that there is a tendency for the one-piece locking head 7' to be locked into the tool body 6 at a position corresponding to the locking recess 6-1.
When the acting force of the reset spring 8 is overcome, the unlocking button 5 is pressed into the insertion hole 3-1 of the box body 3 to be positioned at the unlocking position, the inner end of the unlocking button firstly presses the locking block 10 to enable the locking block to be separated from the locking rod 1, then the wedge-shaped surface 5-1 at the inner end acts on the inclined surface to pry the locking rod 1, the connected lock head 7' is pried to be separated from the position of the clamping recess 6-1 of the clamping tool body 6 to be tripped, and at the moment, the hinged clamping strip and the hinged clamping groove of the box body 3 and the tool body 6 can be smoothly disconnected and mutually separated. When the unlocking button 5 is released, the reset spring 8 makes it in the reset locking position, as shown in fig. 4, at this time, one end of the box body 3 is hinged with the clamping strip 3-3 and is clamped into the hinged clamping groove 6-3 of the corresponding part of the tool body, the conjoined tapered end 7 'of the other end locking rod enters into the locking position clamped into the clamping groove 6-1 of the tool body 6 due to the action of the spring 9', and the locking block 10 clamps the locking rod 1 under the action of the top spring 11, so that the box body 3 and the tool body 6 are mutually and reliably combined together.
Experiments show that the separating structure of the unlocking button and the locking rod not only effectively avoids tripping caused by external disturbance, ensures reliable locking and 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 convenient.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
