Further, the side surface of the backing plate is provided with anti-skid grains.
Furthermore, the height of the limiting clamping block is larger than the thickness of the rubber cushion. The first limiting clamping block can enable the base plate to rotate only within the range of 180 degrees, so that the first limiting clamping block is required to be high enough to prevent the base plate and the inner lining from rotating together to be separated from the external thread of the liquid outlet.
Furthermore, the first limiting clamping blocks are provided with two limiting clamping blocks which are respectively arranged on two sides of the liquid outlet, and the second limiting clamping blocks are provided with two limiting clamping blocks which are respectively arranged on two sides of the round hole.
Under the effect of the elastic rubber cushion, the cushion plate is pushed to tightly abut against the inner bushing, the locking block and the locking groove of the inner bushing can be clamped and embedded in a final phase, the cushion plate is limited to rotate by the limiting clamping block and can only rotate within the range of 180 degrees, the outer cover shell and the inner bushing cannot be separated from the hose body, and therefore the mistaken opening of a child can be effectively prevented. And when the adult need paint this internal emulsion of hose, then can push down the backing plate with the hand, make the compression of rubber cushion, make backing plate and horizontal stand support and lean on, the latch segment then separates with the locking groove this moment, just can easily rotate outer cover shell and neck bush, makes external screw thread and internal thread separation, opens the outer cover shell.
Compared with the prior art, the plastic hose assembly with the oval teeth has the following advantages:
1. the security is high, only needs to push down the backing plate and just can unblock the inside bush, otherwise inside bush and backing plate can only be in 180 rotation within ranges, can't open the outer cover shell.
2. Simple structure compares other hoses, has only increased backing plate and rubber cushion, and manufacturing cost is few, need not unnecessary action during the locking, screw up interior bush and enclosing cover shell can, the unblock mode is also simple.
