Description

Watertap discharging tube and body engagement device

Technical field

The utility model relates to a kind of water tap, particularly a kind of watertap discharging tube and body engagement device.

Background technique

Traditional water tap is made with forging type mostly, because of being subject to the cause of mold, makes the moulding of water tap be subjected to great limitation; Deriving in the process of being cast has many environmental issues, and in recent years at water tap in appearance, is particular about under the shaping-orientation of intention external form gradually, makes the water tap of known one-body molded casting can't satisfy the smart matter market demand at all; Industry is actively to attempt the variation of various intention moulding for this reason, and the main flow of its variation is the change in shape between faucet body and outlet pipe, is illustrated in figure 1 as a typically representative.But the juncture of this faucet body 10 and outlet pipe 11, general all is that faucet body 10 and outlet pipe 11 are welded to form as shown in Figure 2 water tap along seam with welding manner, and its structure is that the osculum 12 of faucet body 10 is connected with outlet pipe 11; Yet this juncture can cause following shortcoming:

1, because the crooked intersection in the three-dimensional space that the faucet body 10 of tubular and 11 of outlet pipes are two surface intersections can be located to form, especially the crossing angle in some place is a dead angle, therefore very difficult on the polishing processing, cost height not only, and the exterior quality that may not be certain after polishing can meet requirement attractive in appearance;

2, welding process often can cause pore problem or rosin joint phenomenon unavoidably, and the pore problem can cause the phenomenon of leaking or seep water, and the rosin joint situation then can cause in conjunction with insecure bumping slightly and connect with regard to easy-rupturing;

3, waste gas and the high temperature that is produced in the welding processing process can cause practitioner's employment injuries.

So, and design preferable water tap connected structure, be the difficulty place that solves for the utility model institute desire row how at the shortcoming that construction caused of above solder bond water tap.

Summary of the invention

The utility model is that a kind of watertap discharging tube and body engagement device will be provided, and makes it exempt highly difficult polishing processing with solution, and reduces because of welding pore and rosin joint and cause the defective products loss, reaches the technical problem that reduces cost.

It is such solving the problems of the technologies described above the technological scheme that is adopted:

A kind of watertap discharging tube and body engagement device, comprise a faucet body, it is to be a hollow cylinder, its upper end is provided with the opening of establishing for leader's seat group, it is characterized in that: the little hole, two rank of the big external diameter of an internal diameter is established in the body front side of this water tap, cooperates an outside thread to take over and an interlocking lock set group one outlet pipe;

This outside thread is taken over, and is the adapter that has an external thread section for, and the one end is established an outward flange, and the inboard neck cover of outward flange is organized a water stop ring, and this outside thread is taken over is axially arranged with a through hole, and an end of the nearly outward flange of this through hole is established a well;

This interlocking cover is to be a hollow body, is respectively equipped with the internal thread that a thread section of taking over for an outside thread is locked at inner and outer surface, and is provided with one and locks outside thread in the inner bolt hole of this outlet pipe for the interlocking cover;

The outer end of this interlocking cover forms one longitudinally with the convenient allocating slot of locking outlet pipe that rotates.

The utility model mainly is that inwall at faucet body is with the little hole, two rank of the big external diameter of an internal diameter, cooperate an outside thread to take over and at one end be convexly equipped with an outward flange, this outside thread is taken over outside the neck cover of flange inner and is organized a water stop ring, and this outside thread is taken over and can be formed sealing embedding group in hole, faucet body two rank with its outward flange by penetrating hole, two rank in the faucet body; Cooperate interlocking cover of an outlet pipe binding end inwall interlocking with internal and external threads, and with the internal thread of this interlocking cover and the external thread section interlocking of outside thread adapter, water tap is inner to be communicated with outlet pipe and form, and outer wall presents the water tap joint of smooth winding, make it exempt highly difficult polishing processing thereby solved, and reduce because of welding pore and rosin joint and cause the defective products loss, reach the technical problem that reduces cost.

The utility model is simple in structure, and its advantageous effect is as follows:

1, it is to make up a water tap in the interlocking mode, removes highly difficult polishing treatment work procedure from, and the cost that can significantly save procedure for processing is attractive in appearance with the lifting finished product;

2, it is to form in the interlocking mode to avoid the defective products that may cause because of pore problem or rosin joint phenomenon, improves the rate of good product of quality, effectively reduces the cost of defective products loss;

3, it is to form high temperature and the waste gas that can avoid because of weld job, the employment injuries that is caused in the interlocking mode.
