Detailed Description

In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.

The first embodiment is as follows:

as shown in fig. 1-7, the heat storage electric boiler convenient for connection of the present invention comprises a heat storage electric boiler 1, a heating water pipe 11 and a corrugated expansion pipe 12, wherein a heating outlet 13 is arranged at the lower side of the rear end of the heat storage electric boiler 1, the heating water pipe 11 and the heating outlet 13 are both fixedly provided with a connector 14, and both ends of the corrugated expansion pipe 12 are both provided with a connection mechanism;

the connecting mechanism comprises a connecting cylinder 15, two hinge lugs 151, two rotating rods 152 and two locking rings 153, the connecting cylinder 15 is fixedly connected to one end of the corrugated expansion pipe 12, the two hinge lugs 151 are symmetrically and fixedly arranged on the side edge of the connecting cylinder 15, the two hinge lugs 151 are positioned on one side of the connecting cylinder 15 close to the corrugated expansion pipe 12, the two rotating rods 152 are respectively hinged to the two hinge lugs 151, a convex block 154 is arranged on one hinged side of the two rotating rods 152, two rotating grooves 155 respectively matched with the two convex blocks 154 are symmetrically formed in the side edge of the connecting cylinder 15, a limiting ring 141 matched with the convex blocks 154 is arranged at the end part of the connecting head 14, an annular groove 142 matched with the convex blocks 154 is formed in the side edge of the connecting head 141, a sealing rubber gasket 16 is arranged between the connecting head 141 and the connecting cylinder 15, the two locking rings 153 are symmetrically hinged to the side edge of the connecting cylinder 15, the two locking rings 153 are positioned on one side of the connecting cylinder 15 far away from the corrugated expansion pipe 12, and a clamping block 156 matched with the locking rings 153 is arranged at the end part of the rotating rods 152.

When the corrugated expansion pipe 12 is installed at the heating outlet 13 of the heat storage electric boiler 1, the connecting head 14 extends into the connecting cylinder 15, the connecting head 14 abuts against the sealing rubber gasket 16 and is close to the inner side of the connecting cylinder 15, then the rotating rods 152 on the two sides are rotated, the protruding block 154 is rotated at the rotating groove 155 and is close to the limiting ring 141, the protruding block 154 rotates to gradually push the limiting ring 141 to abut against the inner side of the connecting cylinder 15, a user can tightly pinch the rotating rods 152 on the two sides with hands, then the locking ring 153 abuts against the clamping block 156 and is rotated to the connecting position of the clamping block 156 of the rotating rod 152 and the rotating rod 152, because the rotating rod 152 and the locking ring 153 have different rotating directions, and the rotating rod 152 has a resetting rotating trend when the protruding block 154 pushes and abuts against, the rotating rod 152 is fixed by the clamping block 156 and the locking ring 153, and the rotating rod 152 is prevented from rotating, and the corrugated expansion pipe 12 can be successfully installed; when the corrugated expansion pipe 12 is disassembled, a user pinches the rotating rods 152 on two sides to enable the clamping block 156 to be not attached to the clamping block 153 any more, at the moment, the clamping block 153 is only needed to be attached to the clamping block 156 to be rotated out, then the rotating rods 152 on two sides are rotated to disassemble the corrugated expansion pipe 12, the assembling and disassembling process is quick, the operation steps are simple, and the work efficiency of the user is improved.
