Description

A kind of drawing pipe and faucet

technical field

The invention relates to the field of kitchen and bathroom, in particular to a drawing pipe and a faucet.

Background technique

At present, there are many types of pull-out faucets on the market, and their shapes are changeable, but basically the structure is similar. Generally, a heavy hammer is installed on the water outlet hose, and two screws are used to lock the weight on the water outlet hose. , use the pulling force generated by the weight of the hammer to reset the spray gun. With this structure, the customer needs to prepare screwdrivers and other installation tools when installing the product, and it is easy for the customer to lock the weight too much when locking the hammer. The hose is deformed, reducing the life of the outlet hose. Moreover, the outlet hose directly passes through the main body of the faucet. Because the main body of the faucet is generally a casting, the smoothness of the inner wall is very poor. The non-smooth casting surface on the inner wall of the main body of the faucet has a lot of friction, which makes the handle feel bad, and even stuck. The other existing one adopts manual return. After use, the pull tube needs to be plugged back under the table, which is inconvenient to operate.

Detailed ways

The present invention will be further described below through specific embodiments.

Referring to FIGS. 1 to 10 , a drawing tube includes a tube body 10 , a movable sleeve 20 , a sleeve body 30 and an elastic tube 40 . The pipe body 10 can adopt a pull-out double button hose. The outer wall of the movable sleeve 20 is provided with two convex points 21, the bottom is provided with a gap, and the inner wall is provided with two elastic sheets 22; Rotatably connected, the movable sleeve 20 is provided with a window 25 for the elastic sheet 22 so that the elastic sheet 22 has a certain space for movement. The movable sleeve 20 is set on the outside of the tube body 10 , and there is a certain amount of interference between the two elastic pieces 22 and the tube body 10 to achieve clamping of the tube body 10 .

The cover body 30 includes an upper cover 31 and a lower cover 32. The upper cover 31 is provided with a plurality of protrusions 38, and the lower cover 32 is correspondingly provided with a plurality of grooves 39. When the bottom end of the upper cover 31 is socketed with the top end of the lower cover 32 , the positioning is realized by snapping the protrusion 38 into the corresponding groove 39 . The bottom of the upper sleeve 31 is provided with first wave grooves 33 distributed around the circumference, and the first wave grooves 33 extend from bottom to top and have a plurality of wave crests 33a. The top of the lower sleeve 32 is provided with second wave grooves 34 distributed around the circumference, and the second wave grooves 34 extend from top to bottom and have a plurality of wave troughs 35 . The first wave groove 33 communicates with the second wave groove 34 to jointly form a guide groove, and the several wave crests 33a and the several wave troughs 35 are distributed alternately or alternately along the circumferential direction. The sleeve body 30 is sleeved outside the movable sleeve 20, and the convex point 21 of the movable sleeve 20 is located in the guide groove and forms a guide structure with the guide groove. When the pipe body 10 and the movable sleeve 20 are pulled, the guide structure can drive The movable sleeve 20 rotates. During the rotation of the movable sleeve 20, the protruding point 21 slides between the crest 33a and the trough 35. The sliding track of the protruding point 21 can be seen in FIG. 8 . In addition, a limiting flange is provided on the top of the upper sleeve 31 to prevent the movable sleeve 20 from detaching from the sleeve body 30 .

Further, the inner wall of the lower sleeve 32 is also provided with a plurality of circumferentially distributed protrusions 36 , and recesses 37 are formed between adjacent protrusions 36 , and both the protrusions 36 and the recesses 37 are located below the guide grooves. The snap button 23 of the sliding sleeve forms a positioning structure with the convex post 36 and the concave cavity 37. The snap button 23 is also provided with a button head 23a. 37 drives the buckle head 23a to fasten or loosen the pipe body 10.

The elastic tube 40 can be a spring tube, and a connector 41 is provided on the top end thereof. The drawing tube of the present invention further includes a bushing 50 , which is sheathed outside the sleeve body 30 and used for fixing other parts. One end of the elastic tube 40 is connected with the tube body 10 , and the connecting head 41 at the top is fixedly connected with the bottom of the bushing 50 . When the tube body 10 is pulled, the elastic tube 40 is compressed; when the buckle 23 releases the tube body 10 and the external force for pulling the tube body 10 is eliminated, the tube body 10 returns to its position under the action of the elastic tube 40 .

The present invention also proposes a pull-out faucet, which includes a faucet and the above-mentioned pull-out pipe. The top of the pipe body 10 of the pull-out pipe is provided with a joint 11 , and the faucet is connected to the joint 11 of the pipe body 10 . The faucet can also be replaced with other water outlets such as a shower.

The number of wave crests 33 a and troughs 35 and the numbers of convex posts 36 and concave cavities 37 of the pull-out tube and faucet of the present invention are geometric sequences, which can be set according to application occasions or specific requirements. As shown in FIG. 8 , taking the movable sleeve 20 to rotate 45° as a cycle, the protruding point 21 passes from position a along the track to b, and finally reaches c. During this period, the buckle 23 is switched from releasing the tube body 10 to clamping the tube body 10 . The specific working principle is as follows:

When the tube body 10 is pulled upward for a certain length, the elastic tube 40 is compressed, and the tube body 10 moves up. During the upward movement, due to the action of the guiding structure, the movable sleeve 20 rotates at a certain angle, and the convex point 21 slides from a to b along the track. At the same time, due to the effect of the positioning structure, the buckle 23 rotates around the pin 24 from loosening the tube body 10 to clamping the tube body 10 to realize positioning. At this time, if the external force applied to the tube body 10 is eliminated, the tube body 10 is still Hold that position. When the pipe body 10 is pulled upwards for a certain length, the movable sleeve 20 continues to rotate at a certain angle, the convex point 21 slides from b to c along the track, and the buckle 23 rotates around the pin 24 to change from clamping the pipe body 10 to releasing the pipe body 10. body 10, at this time, if the external force of pulling the tube body 10 is eliminated, the elastic tube 40 returns to its position, driving the tube body 10 to move down to realize automatic reset.

The above is only a specific embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any non-substantial changes made to the present invention by using this concept should be an act of violating the protection scope of the present invention.
