Description

Pull-type faucet structure

The invention relates to a faucet structure, in particular to a low-cost pull-type faucet structure made of plastic.

According to a conventional faucet structure, such as the "Drinking Faucet with Plastic Diversion Core" approved by the Department of Economics on April 21, 1983, which mainly includes: a metal body, The metal system defines a longitudinal axis, the top end of which is provided with an outlet pipe along the axial direction of the longitudinal axis, the metal body is provided with a through chamber in the axial direction, and the chamber has an opening, and the metal a hollow tubular water valve core receiving portion is disposed in a lateral direction of the outer peripheral wall of the body, and the long water valve core receiving portion is further provided with a long shaft valve core, and the long shaft valve core is connected to a valve core control member. There is a control rod on the valve core control member. It is not difficult to find out that the above-mentioned conventional structure has some shortcomings. The main reason is as follows: the faucet shell is a metal body, and the metal body needs to be drilled and The inner teeth of the turning have different diameters and inner threads, and the processing time and cost are high, and the metal body is fixed by screw locking, so that the metal body needs to have a considerable thickness, which not only causes the internal to shrink but also increases its Weight and The cost of the material, if the plastic casing is used instead of the metal casing, the plastic casing will also be unable to be made into a thin shell because of the need to process the internal thread, and the cost of opening the mold and the material cost cannot be effectively reduced, and the screw inside the plastic casing is It is easy to be deformed during electroplating, which increases the defect rate of its products. This is the technical problem that the author wants to solve.

In view of this, the inventor has been engaged in the manufacturing development and design of related products for many years. Experience, after the detailed design and careful evaluation of the above objectives, the invention will be practical.

The technical problem to be solved by the present invention is to provide a pull-type faucet structure in view of the above-mentioned shortcomings existing in the prior art.

A valve seat is formed at one end of a plastic body, and a control valve is mounted on the valve seat, and the control valve is coupled with a handle for controlling the water discharge switching, and the valve seat is provided with a first external thread on the outer periphery of the opening. Further, the other end of the plastic body integrally extends with a ring, and the outer edge of the ring is formed with a second external thread, and the ring axis and the valve seat axis form an angle of between 20 degrees and 30 degrees. The bottom of the valve seat is connected with a cold water hole, a hot water hole and a water outlet hole, and the plastic body passes through the ring with a cold water pipe, a hot water pipe and an outlet pipe, and is corresponding to the cold water hole and the hot water. The hole and the water outlet are connected to the valve seat to communicate with the control valve, and a plastic outer casing is formed in a thin shell shape with a bottom opening, a top opening and an inclined tube which are in communication with each other, and the bottom opening is coaxial with the top opening a slanted tube is formed in the shape of a heart, and the slanted tube of the plastic housing is provided with the accommodating opening, and the rim of the plastic body is disposed at the bottom opening. And the loop and the bottom The opening is coaxial, and the valve seat of the plastic body is disposed coaxially in the receiving opening, a locking sleeve is formed with a first internal thread, and the locking sleeve is locked to the plastic body by a first internal thread The first external thread allows the locking sleeve to press against the receiving opening of the plastic casing, so that the plastic casing cannot be separated from the plastic body by the locking sleeve, and a water outlet pipe is connected to the top opening of the plastic casing, and The water outlet pipe is connected to a hose and extends to the water outlet pipe. The body body is formed with a second internal thread, and the second internal thread is locked to the second external thread of the plastic body, so that the seat body is resisted. The bottom of the plastic case is open The lock sleeve is clamped to fix the plastic outer casing.

Wherein, the valve seat of the plastic body protrudes from the surface with a stopper, and the plastic casing has a notch recessed in the inner wall surface of the inclined pipe, and the stopper is embedded in the notch so that the plastic body cannot be accommodated by the plastic casing The open end is pulled out and can form a snap-fit effect at the time of assembly.

The seat body is formed with a locking portion, and a locking plate is screwed from the locking portion, and the locking plate allows the seat body to be externally formed and fixed.

Wherein, the seat body and the lock sleeve are made of plastic material

Wherein, the water outlet pipe is provided with a water outlet head at the other end of the connecting plastic shell, and the water outlet head is connected to the hose, and the hose can be pulled to form a pulling function of the water head.

Wherein, the lock sleeve is formed with a screw locking portion on the inner edge, and a pressure ring is locked by the screw locking portion, and the pressure ring presses the control valve, thereby improving the tightness of the combination of the control valve and the valve seat.

The first main object of the present invention is that the plastic casing is directly formed with a bottom opening, a top opening and an inclined tube for the plastic drawing process, and the plastic body is placed in the inclined tube, and the plastic body is locked by the locking sleeve.
