Abstract

The utility model discloses a connecting device between cold/hot tap and cold/hot water pipe built in wall. Because the cold/hot water pipe is usually built in the wall, the construction error is the position deviation of the central shaft of the hot and cold outlets of the pipes. The previous connecting device can not overcome the horizontal deviation of the two central shafts in installation. The phenomenon that the screw threads of the connecting part can not be sheathed or be arranged firmly appears. The connecting device of the utility model changes the stair columnar connector previously sheathed in the cap nut into a spherical joint. The cap nut can swing optionally around the spherojoint. Even if the central shaft of the outlet of the cold/hot water pipe is non-parallel, the tap can be firmly and tightly arranged on the wall conveniently. The installation is not limited by the built-in pipeline construction level. The utility model can be extensively applied to various bathe locations such as bathtub, shower or kitchen.

Description

The connection set of water tap and built-in body of wall cool and hot water pipe

Technical field

The utility model relates to a kind of connection set, the connection set that particularly a kind of hot and cold water tap cool and hot water pipe interior with being built in body of wall is connected.

Background technique

Hot and cold water generally is used for various bathings place with water tap at present, and the water tap of the two water inlets of hot and cold water that have all can be installed and use as bathtub, shower or kitchen etc.Aspect installation, the hot and cold water pipeline all is embedded in the body of wall usually, only leave the hot and cold water pipe water outlet at surface of wall, when water tap is installed, the use connection set should be cold, the hot water pipeline water outlet is cold with water tap respectively, hot water intake is connected, this connection set as shown in Figure 1, comprise bent pin 1 ' and link 2 ', one end of the bent pin 1 ' cool and hot water pipe interior with being built in body of wall is connected, the other end is cold by link 2 ' and water tap, the hot water mouth connects, described link 2 ' comprises the nut 21 ' that is connected with bent foot, be set with water tap cold in the counterbore of nut 21 ', the hot water mouth holds the cylinder-shaped joint 22 ' of connection, and joint 22 ' is equipped with rubber cushion 23 ' with bent pin 1 ' connecting part.Because the hot and cold water pipeline is in pre-buried body of wall the time, alignment error in various degree can appear, substantially horizontal centre distance error during as two water outlet central axes or Vertical direction centre distance error, such error can be eliminated by adjusting bent pin, if but two water outlet central shafts are not parallel, as high on one side, low on one side, then adjusting bent pin in any case all can't eliminate, with link 2 ' after water tap is installed when docking with bent pin, under the restriction of cylinder-shaped joint 22 ', nut 21 ' can only move up and down and can not swing, and the result that nut and bent pin are not threaded even can't install will occur.Therefore, the structural design of this link 2 ' is had relatively high expectations to the construction level of pre-buried pipeline, and the central shaft of two water outlets must parallel ability be installed smoothly.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of pre-buried pipeline construction horizontal constraints, connection set easy for installation of not being subjected to, and can eliminate the central axes error of hot and cold water pipe water outlet.

The technological scheme that its technical problem that solves the utility model adopts is:

The connection set of a kind of water tap and built-in body of wall cool and hot water pipe, comprise bent pin, the one end cool and hot water pipe interior with being built in body of wall is connected, the other end is connected by the hot and cold mouth of a river of link and water tap, described link comprises the nut that is connected with bent foot, is set with the joint that is connected with the hot and cold mouth of a river of water tap end in the counterbore of nut, and rubber cushion is equipped with in joint and bent pin connecting part, it is characterized in that described joint is a spherojoint, its part that is sleeved in the nut is sphere; Inner hexagonal hole is arranged at described spherojoint top; Described rubber cushion is spherical glue, and its end that contacts with joint is sphere.

The beneficial effects of the utility model are: because the joint that is connected with the hot and cold mouth of a river of water tap end on the link is a spherojoint, its part that is sleeved in the nut is sphere, when then nut docks with bent pin, nut can adapt to the deviation of flex-foot shaft line and arbitrarily swing, until both screw thread precessions smoothly, thereby overcome the not parallel problem of bringing of hot and cold water pipe water outlet central shaft, easy for installation, be not subjected to the restriction of pre-buried pipeline construction level; Inner hexagonal hole is arranged at the spherojoint top, is convenient to instrument spherojoint is connected with the installation of water tap water intake; Rubber cushion is spherical glue, and its end that contacts with joint is sphere, and like this rubber cushion is cooperated with spherojoint tightr, and the connection of whole connection set also more closely, reliably.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the assembly structure schematic representation of connection set and water tap in the prior art;

Fig. 2 is the assembly structure schematic representation of the utility model and water tap;

Fig. 3 is the utility model embodiment's a structural representation.

Embodiment

With reference to Fig. 2, Fig. 3, connection set of the present utility model, comprise bent pin 1 and link 2, one end of bent pin 1 cool and hot water pipe interior with being built in body of wall is connected, the other end is connected with the hot and cold mouth of a river of water tap by link 2, link 2 comprises nut 21, spherojoint 22, nut 21 is connected with bent foot, be set with the spherojoint 22 that is connected with the hot and cold mouth of a river of water tap end in its counterbore, spherojoint 22 is equipped with rubber cushion 23 with bent pin 1 connecting part, and the part that spherojoint 22 is sleeved in the nut 21 is sphere.

Because spherical joint is sleeved in the nut and can multi-angle arbitrarily rotates, when nut docks with bent pin, nut can adapt to the deviation of flex-foot shaft line and arbitrarily swing, until both screw thread precessions smoothly, even hot and cold water pipe water outlet central shaft is not parallel, can install smoothly too, very convenient, be not subjected to the restriction of pre-buried pipeline construction level.

Inner hexagonal hole is arranged at the top of spherojoint 22, is convenient to instrument spherojoint is connected with the installation of water tap water intake.Spherojoint 22 is spherical glue with the rubber cushion of bent pin 1 connecting part, and its end that contacts with joint is sphere, and like this rubber cushion is cooperated with spherojoint tightr, and the connection of whole connection set also more closely, reliably.

For the water of going into the water tap from channel flow is further filtered, at bent pin 1 and the end that nut 21 joins filter screen 3 is housed, with reference to Fig. 3, this filter screen one end withstands bent pin counterbore 11 bottoms, and the other end withstands rubber cushion 23 by sleeve 4 and is sleeved in the bent pin counterbore.

Bent pin 1 in this connection set is with after pipe water outlet is connected, can be outside bent pin suit trim 4, so not only attractive in appearance, also decorated metope, make the one integrated mass that is connected of water tap and body of wall, high-grade attractive in appearance.
