Detailed Description
The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, the coupler is axially provided with a through hole 11, a sleeve 3 is arranged in the through hole, a first limiting part is arranged on the circumferential wall of the sleeve, a second limiting part is arranged on the lower water inlet pipe, one end of the lower water inlet pipe extends into the sleeve and then rotates to pass through the second limiting part and the first limiting part to block and match to prevent the lower water inlet pipe from being separated from the sleeve in the axial direction. This spacing portion of first spacing portion and second can be the boss, and the inlet tube stretches into back rotatory back two bosses down and realizes placing the back and withdraw from to last, also can be external screw thread and internal thread, also can be recess and bellied structure.
In this embodiment, as shown in the figure, the first limiting portion is an inlet groove 31 and a fixing groove 32 which are communicated with each other, the second limiting portion is a protrusion 21 which is arranged on the outer wall of the lower water inlet pipe, and the protrusion is arranged in the fixing groove through the inlet groove and is used for preventing the lower water inlet pipe from being pulled out of the sleeve in the axial direction. During the installation, stretch into the arch from getting into the groove, then rotatory lower inlet tube, the arch gets into the fixed slot in order to prevent down that the inlet tube is axial to be prevented deviating from down.
In this embodiment, as shown in the figure, the inlet slot is vertically arranged opposite to the fixing slot, and the inlet slot is arranged parallel to the axis of the sleeve.
In this embodiment, as shown in the figure, the inner wall of the sleeve is provided with a first boss 33, the outer wall of the lower water inlet pipe is provided with a second boss 34, the protrusion abuts against the side wall of the fixing groove, and the first boss is in limit fit with the second boss. When the lower water inlet pipe is installed in place, the first boss and the second boss are abutted to prevent the lower water inlet pipe from reversely rotating, and if the lower water inlet pipe is to be taken down, the lower water inlet pipe needs to be rotated vigorously, so that the conventional state can be prevented from being separated.
In this embodiment, as shown in the figure, the first boss includes a first inclined surface 331 and a first blocking surface 332, the second boss includes a second inclined surface 341 and a second blocking surface 342, the second inclined surface is in sliding fit with the first inclined surface, and the second blocking surface is in abutting press fit with the first blocking surface. When the water inlet pipe rotates, the first blocking face and the second blocking face are in contact with each other to prevent the water inlet pipe from rotating reversely when the water inlet pipe rotates to the bottom of the right side of the fixing groove through the first inclined face and the second inclined face in sliding fit, and therefore the water inlet pipe is convenient to install.
In this embodiment, the cross-section of the protrusion is circular, as shown.
In this embodiment, as shown, the lower inlet pipe is an L-shaped pipe.
In the present embodiment, as shown in the figure, a support plate 5 for placing the sleeve is arranged in the through hole, and a through groove 51 for the lower inlet pipe to pass through is arranged on the support plate. The through groove can be used for the protrusion to pass through, the pressing plate is arranged on the sleeve, and the spring is arranged between the pressing plate and the support plate, so that the through groove is omitted in the prior art.
