Description

Telescopic positioning structure for faucet outlet pipe

The invention relates to a faucet structure, in particular to a telescopic positioning structure for a faucet outlet pipe.

According to this, the faucet is one of the indispensable water supply tools in human life, and the development of the faucet has also contributed to the progress of human beings more and more particular about the application of "washing methods", such as in the sink, flow table, and washstand. Different faucet structure designs are gradually used for washing to provide consumers with more diversified special styles. They are all extended designs of faucets. Because of these faucets designed for special purposes, it is more convenient for people to use water. the way.

Generally, the faucets installed in the flow table are mostly vertical design. For the convenience of water control, the water control valve is often planned to be located on the side of the faucet body, and the outlet pipe is located on the top of the faucet body. However, this type of faucet faces the need for cleaning after the flow table is used. Because the water outlet range of the outlet pipe cannot cover the entire flow table, the industry has developed an inner tube type faucet, and a soft type is installed in the outlet pipe. The inner tube, after one end of the soft inner tube passes through the body of the faucet, is connected to the outlet solenoid connected to the water control valve, and the other end of the soft inner tube is assembled with a water outlet, and the outlet must be sleeved Place it on the outer end of the outlet pipe. In this way, in addition to the normal water type, when faced with cleaning the flow table or other large-scale water needs, the soft inner pipe can be pulled out by the outlet And extend the water outlet to the place where you want to use water, so as to provide a flexible water type and give better practical value.

However, the conventional inner tube type faucet has no positioning design when the outlet head is stretched outwards. Therefore, continuous force is required to keep the outlet head in a stretched state, which causes inconvenience and laborious operation. The design of the faucet body is equipped with a soft inner pipe. Because the faucet is equipped with water control valves, inlet and outlet pipes and other related components, only the remaining clearance space can be used for the soft inner pipe to pass through. A counterweight is arranged on the inner tube, and the soft inner tube is pulled down by the weight of the counterweight. As a result, the volume of the faucet body is large, and special structural design is required. Moreover, the space is not straight and unobstructed. The bendable and flexible form of the soft inner tube causes it to be hindered or interfered by the internal water control valve when the soft inner tube passes through the faucet body from the outlet pipe port, which may hinder or be difficult to complete the installation work. Affect the smoothness and work efficiency of its wear group.

In view of the above-mentioned shortcomings of the conventional inner-tube faucet, the inventors developed the present invention based on the idea of thinking and creation, after many discussions, trial sample tests, and many modifications and improvements.

The inner wall of the through hole 311 is provided with a plurality of detent protrusions 314 arranged at intervals in a ring shape, and a guide groove 315 is respectively formed between each adjacent detent protrusion 314.

The soft inner tube 40 is slidably inserted into the outlet pipe 20. One end of the soft inner tube 40 is provided with a connecting portion 41. The connecting portion 41 is provided with a blocking edge 411, and the connecting portion 41 penetrates the inner sleeve. In the pipe 31, the other end of the soft inner pipe 40 is combined with an outlet head 42 on the outside of the outlet pipe 20. The outlet head 42 is sleeved and clamped to the opening 22 of the outlet pipe 20 in a normal state, and can be combined with the outlet pipe 20 according to the needs of use. The soft inner tube 40 is stretched outward.

The guide member 50 is provided with a set of holes 51 in the center. The guide member 50 is rotatably and displaceably sleeved on the outer edge of the connecting portion 41 of the flexible inner tube 40 through the sleeve hole 51. The inner wall of the sleeve hole 51 is convex at the lower end. A positioning portion 511 is provided. A plurality of positioning ribs 52 are arranged on the periphery of the guide member 50 at intervals, and the lower end of the guide member 50 is provided with continuous guide teeth 53.

The sliding member 60 is in a hollow tube shape and is slidably arranged in the inner sleeve 31. The inner edge of the upper end is connected to the connecting portion 41 of the soft inner tube 40, and the outer edge of the upper end is provided with a plurality of guide ribs 61 arranged at intervals in a ring shape. , The upper end is provided with a continuous push-rotating convex tooth 62, and the lower end is provided with an enlarged convex block portion 63. The outer edge of the convex block portion 63 is sleeved with at least one water stop ring 631 (in this embodiment, the convex block portion 63 is sleeved on Two water stop rings 631) are provided, which slide against the inner wall of the inner sleeve 31.

The spring 70 is set in the accommodating hole 312 of the inner sleeve 31 and sleeved on the outer edge of the soft inner tube 40 and the sliding member 60. One end of the spring 70 abuts against the upper end of the accommodating hole 312. The other end of the edge 313 abuts against the protrusion 63 at the lower end of the sliding member 60.

When in use, under normal water usage, the water outlet cutting control unit 11 controls the ratio of cold and hot water inlets and the water supply and stop functions, so that the outlet water can pass through the faucet body 10 and the soft inner tube 40, which is controlled by the soft inner tube 40. The outlet head 42 flows out. When facing the water demand for cleaning the flow table or other larger areas, as shown in Figures 7 to 12, the outlet head 42 together with the soft inner tube 40 can be stretched out to stretch the water outlet 42 together with the soft inner tube 40 as shown in Figures 7-12. The water outlet extends to the required water location, giving a larger range of water functions. At this time, the sliding member 60 is driven upward by the soft inner tube 40, and at the same time, the sliding member 60 pushes the guide member 50 upward together. , So that the spring 70 is contracted by the protrusion 63 of the sliding member 60, the positioning rib 52 of the guiding member 50 is aligned with the guiding groove 315 of the inner sleeve 30 and sliding upward, and the guiding rib 61 of the sliding member 60 Align the guide groove 315 of the inner sleeve 30 and slide upward until the positioning rib 52 of the guide member 50 escapes from the guide groove 315 of the inner sleeve 30, and is pushed by the continuous pushing and rotating protruding teeth 62 of the sliding member 60 The continuous guiding convex tooth 53 of the guiding member 50 drives the guiding member 50 to rotate at a small angle, and the positioning rib 52 of the guiding member 50 changes to align with the latching convex portion 314 of the inner sleeve 30, The positioning rib 52 of the guide member 50 is locked against the locking protrusion 314 of the inner sleeve 30 for positioning, and the stop edge 411 of the connecting portion 41 of the soft inner tube 40 is locked against the guide The positioning portion 511 of the sleeve hole 51 of the piece 50 reaches the position of positioning the water outlet 42 in a stretched state.

When the stretched spout 42 is to be retracted, the spout 42 together with the soft inner tube 40 is stretched out slightly. The sliding member 60 is driven upward by the soft inner tube 40 and is continuously pushed and rotated by the sliding member 60 The convex tooth 62 pushes against the continuous guiding convex tooth 53 of the guiding member 50 to drive the guiding member 50 to rotate at a small angle. The positioning rib 52 of the guiding member 50 transforms and aligns the guide of the inner sleeve 30 When the groove 315 is released from the positioning effect, the soft inner tube 40, the guiding member 50 and the sliding member 60 can be automatically returned to their original positions by the return elastic force of the spring 70, and at the same time the water outlet 42 is retracted to re-set the card Fitted to the opening 22 of the outlet pipe 20.
