the blocking wall is provided with a gap, the plug penetrates through the insertion cavity and is inserted into the socket, the buckle enters the insertion cavity through the gap, and the male head part rotates relative to the female seat part to enable the buckle to be abutted against the inner wall of the blocking wall;

the blocking wall is attached to the base.

Furthermore, the outer walls of the male head part and the female seat part are respectively provided with a first mark arrow, and the positions of the first mark arrows correspond to each other, so that the buckle is aligned with the notch.

Furthermore, a second mark arrow used for indicating the rotation locking or unlocking of the male head is arranged on the side wall of the base.

Furthermore, a blocking block perpendicular to the blocking wall is arranged on the inner side wall of the insertion cavity, and the buckle abuts against the blocking block to limit the maximum rotation angle of the male head relative to the female seat part.

The utility model has the beneficial effects that:

the male head part is fixed on the female seat part through the buckle and fixed in a clamping and fixing mode, compared with a static friction fixing mode in the prior art, the connection is more stable, the phenomenon that the male head part can be opened through simple dragging due to external force such as mistaken touch is avoided, and the stability of circuit connection is improved.

Detailed Description

In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit the utility model.

Referring to fig. 1 to 5, the present invention discloses a waterproof power plug set with a lock, including: male head 1 and female seat 2, said female seat 2 comprising: socket 21, set up in the socket 21 front end be cylindrical the setting insert chamber 22, and set up in insert chamber 22 open end keep off wall 23, male portion 1 includes: the plug comprises a plug 11, a base 12 arranged at the tail end of the plug 11, a buckle 13 arranged on the base 12, and a base 14 arranged at the tail end of the base 12.

The blocking wall 23 is provided with a gap 24, the plug 11 passes through the insertion cavity 22 and is inserted into the socket 21, the buckle 13 enters the insertion cavity 22 through the gap 24, and the male head part 1 rotates relative to the female seat part 2 to enable the buckle 13 to be abutted against the inner wall of the blocking wall 23. After the rotation, the buckle 13 and the blocking wall 23 are abutted against each other, and when an external force acts on the male head part 1 or the female seat part 2, the buckle 13 can effectively prevent the male head part 1 from being separated from the female seat part 2, so that a stable fixing effect is achieved, and a circuit is prevented from being broken.

The wall 23 abuts against the base 14 in order to close the insertion cavity 22 by means of the wall 23 and the base 14, so that liquid or dust is prevented from entering the insertion cavity 22 and electric leakage is prevented.

The outer walls of the male head part 1 and the female seat part 2 are both provided with first marked arrows 25, and the positions of the first marked arrows 25 correspond to each other, so that the buckle 13 is aligned with the notch 24. When the male head part 1 and the female seat part 2 are inserted in a butt-joint mode, an operator can observe the male head part 1 and the female seat part 2 from the side, although the position of the buckle 13 is visible, the position of the notch 24 is not easy to observe, in order to avoid that the operator cannot align the notch 24 and the buckle 13, the utility model is respectively provided with a first mark arrow 25 on the outer walls of the male head part 1 and the female seat part 2, when the first mark arrows 25 are aligned with each other, the position of the buckle 13 is aligned with the notch 24, and the operator can conveniently align the male head part 1 and the female seat part 2.

A second marked arrow 15 for indicating the rotation locking or unlocking of the male head 1 is arranged on the side wall of the base 14. In a practical embodiment of the utility model, the directions of indication of the second marked arrow 15 and the first marked arrow 25 are mutually perpendicular.

A stop block 26 perpendicular to the stop wall 23 is disposed on the inner side wall of the insertion cavity 22, and the maximum rotation angle of the male head portion 1 relative to the female seat portion 2 is limited by the clip 13 abutting against the stop block 26. The problem of tripping caused by too large rotation angle of the buckle 13 is avoided.

The male head part 1 is fixed on the female seat part 2 through the buckle 13 and fixed in a clamping and fixing mode, compared with a static friction fixing mode in the prior art, the connection is more stable, the phenomenon that the male head part can be opened through simple dragging due to external force such as mistaken touch is avoided, and the stability of circuit connection is improved.

It is to be understood that the utility model is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the utility model as defined by the appended claims.
