Description

Quick joint structure for bathtub drain pipe joint

This creation is about a technical field related to sanitary lavatory equipment, especially the drainage pipe set under the washstand, which is a combination of quick joints.

According to the lavatory for draining the waste water, a drain pipe group is connected to the water outlet of the washstand. As shown in the fourteenth and fifteenth figures, the bathtub 90 is connected to a drain pipe set 70, and the water drop head is provided in the bathtub 90. a water outlet 91 of 92, connected to a horizontal first row of tubes 71, two second and three rows of tubes 75, 751 which are straight and connected to the bathtub overflow head 93, and one connected to the first, second, The three-way pipe 73 of the three-row pipe 71, 75, 751; the drainage pipe group 70 is connected and combined, and the second and third-row pipes 75, 751 are inserted through the glue, and are glued and connected to the two ends of the three-way pipe 73. The tube end of the first row of tubes 71 is also inserted into one of the tube ends of the tee tube 73 by gluing.

The drainage pipe set 70 of the fourteenth and fifteenth diagrams is connected and combined by gluing, and the following problems will occur: when the pipe is to be changed in the future, the first row of pipes 71 and the second row of pipes 75 must be sawed and then re-cut. Inserted and glued to the new U-shaped tube 73, the operation is complicated, and the glue is not resistant to high temperature. If the dredging agent is used in the drain pipe group 70, high temperature is often generated, so that the U-shaped pipe 73 and the first and second pipes are 71. The glue of 75 reduces the viscosity, even degumming to loosen and lose the gluing function, so that the drain pipe group 70 is leaking at the degumming point.

There are also different combinations. For example, the sixteenth, seventeenth and eighteenthth drawings are the combination of the drainage pipe sets 80 of the bathtub in a threaded manner, and the combination of the pipes of the drainage pipe group 80 is relatively simple; The nozzle 91 is connected to a horizontal first row of tubes 81, a second row of tubes 83 for direct connection to the bathtub overflow head 93, and a T-shaped tube 82 connected to the first and second rows of tubes 81, 83; The T-shaped tube 82 has a T shape, one end is connected to the second row of tubes 83, and the other horizontal tube end is connected to the first row of tubes 81. The drain tube group 80 is screwed to the T-shaped tube 82 for corresponding first, The two rows of tubes 81 and 83 are respectively provided as a threaded end 84. The inner end of the threaded end 84 is an inner ring side 841 of the inclined surface, and the inner side of the inner ring side 841 is mounted with a forced ring 85 for tapering the outer side of the ring 85. Corresponding to the inner ring side 841, and a nut 86 is correspondingly engaged with the threaded end 841; therefore, when combined, the first and second rows of tubes 81, 83 are respectively threaded at one end, respectively, through the nut 86, and second, the first and second rows The tubes 81, 83 each extend into the tube of the T-shaped tube 82, and the nut 86 is threadedly engaged to the threaded end 84, respectively, by the threaded end of the nut 86 The force applied by the screw engagement force exerts a downward pressing force on the forced ring 85, causing the tapered surface on the outer side of the forced ring 85 to slide down along the tapered surface of the inner ring side 841, so that the force ring 85 follows the sliding force. The outer side surfaces of the first and second rows of tubes 81 and 83 are more and more tight, and the purpose of the combined drain pipe group 80 is achieved.

However, in the prior art in which the sixteenth to eighteenth drawings are combined by the thread joining means, the thread gap is originally provided with a tolerance gap, plus a material change. After a period of time, the gap between the threaded joints will expand, the force of the nut 86 pressing the ring 85 will gradually weaken, and the elastic material of the forced ring 85 will age, so that the forced ring 85 faces the outer sides of the first and second rows of tubes 81 and 83. The tightening ability is deteriorated, so that the water leaks through the leak, even if the leak-proof tape is wrapped around the threaded end 84, and then threadedly engaged with the nut 86, the damage of the material of the leak-proof tape may cause damage, which is difficult. It is still difficult to avoid the gap in the threaded joint, and therefore the configuration of the threaded joint, which will have the aforementioned problems in the long run and needs to be solved.
