And the center axis of runner shaft, the center line of linear groove 114, the center line of horizontal groove and the center line of second threaded hole 116 are all on a horizontal plane, thereby make the applied force of relying on wheel 4 can not produce component force, can more Effectively, the movement of the ball in the linear groove 114 is also smoother. The shaft hole of the auxiliary wheel shaft holding unit 117 is located above the horizontal groove. Auxiliary wheels are set to limit the position of the pull tube or pull rope, and the lifting movement is not easy to be deformed.

In this embodiment, the idler wheel 4 is supported by the idler shaft holding unit 115, that is, the horizontal groove, so that it can slide horizontally and rotate. Adjusting screw 7 is threaded with second threaded hole 116 and then stretches into box body 11 to push against pin 6. Pin 6 is horizontally arranged in the horizontal groove of wheel-holding shaft unit 115, and pin 6 pushes against wheel 4 again, so that The pulley 4 is close to the pull tube or the stay cord, so that the draw tube or the stay cord and the running wheel 3 can only roll relative to each other, but cannot slide relative to each other. By adjusting the depth that the adjustment screw 7 is screwed in, the horizontal position of the pulley 4 can be adjusted to reduce or increase the pressure of the pulley 4 to the pull pipe or stay rope. By setting the adjustment screw 7, it is possible to adjust the lateral force of the pulley 4 on the pull tube or the pull rope, so that it can adapt to pull pipes or pull ropes of different calibers, and can also adjust the lateral force for pull tubes or pull ropes with different outer surfaces. .

By setting the connecting nut 8, the hovering positioning device can be screwed and fixed with the lower casing of the pull-out faucet, so as to realize the fixing of the hovering positioning device relative to the hose.

In this embodiment, the runner 3 includes a positioning wheel 31 and a friction sleeve 32 , and a positioning surface 310 is also provided on the positioning wheel 31 . The positioning surface 310 faces the straight groove 114 . The friction sleeve 32 is sheathed on the turning surface of the positioning wheel 31 and connected with the positioning wheel 31 through a spline. By arranging the friction sleeve 32, the frictional force is increased, making it less likely to slip between the runner 3 and the pull tube or pull rope. The positioning wheel 31 and the friction sleeve 32 are splined to prevent relative rotation between the positioning wheel and the friction sleeve. The positioning surface is provided with ball grooves, and the balls 2 cooperate with the linear grooves 114 and the ball grooves on the positioning surface 310 respectively.

In this embodiment, the ball groove includes a first arc segment 311 , a second arc segment 312 and a third arc segment 313 .

One end of the second arc segment 312 is provided with a stop position 3121 , and the other end 3122 of the second arc segment 312 reversely cuts the outside of the third arc segment 313 after being reversely rotated from the stop position 3121 .

One end 3111 of the first arc segment 311 cuts along the outer side of the second arc segment 312 and thus connects to the parking position 3121 . After the first arc segment 311 is reversely rotated from the above-mentioned one end 3111 , the other end 3112 reversely cuts the outside of the first arc segment 311 itself.

One end 3131 of the third arc segment 313 reversely cuts the inner side of the first arc segment 3131, and the third arc segment 313 rotates forward from the above-mentioned one end 3131, and then the other end 3132 cuts forward the inner side of the third arc segment 313 itself. inside.

And the groove depth of each cutting end is smaller than the groove depth of the cut section; the reverse direction is the direction of rotation of the positioning surface when the pull tube or stay rope moves downward; the forward direction is the positioning surface when the pull pipe or stay rope moves upward turn around.

The embodiment of the above-mentioned hovering positioning device is applied to a pull-out faucet as shown in FIG. The casing 200, the lower casing 400 fixedly connected to the faucet body 100 and the hovering positioning device 1500 are arranged behind the upper casing 200, the faucet body 100, the lower casing 400 and the hovering positioning device 500 in sequence A flexible hose 600 connected to the water inlet pipe, and the other end of the flexible hose 600 is connected with a water nozzle 300 . Under the hovering positioning device 500 , the hose 600 is also fixedly connected with a weight 700 .

The user can adjust the horizontal position of the pulley 4 by adjusting the screw-in depth of the adjusting screw 7, so as to reduce or increase the pressure of the pulley 4 on the pull tube or the pull rope, so that only the hose 600 and the pulley 3 can relative scrolling.

The user pulls out the nozzle 300 to pull out the hose 600 , the runner 3 rotates forward, and the ball 2 moves reversely. If the initial position of the ball 2 is located in the third arc segment 313, after the ball 2 reversely moves, it will cut into the first arc end 311 from one end 3131 of the third arc end 313, and can reversely circle in the first arc segment 311 without hindrance .

If the user no longer needs to pull out the hose 600, the hose 600 is retracted slightly and moves downward, the runner 3 rotates in reverse, and the ball 2 moves forward relatively speaking. At this time, the ball 2 will cut into the second arc segment 312 from one end 3111 of the first arc segment 311, and continue to move in the reverse direction to the stop point 3121. At this point, the ball 2 can no longer move in the forward direction, so the runner 3 can no longer rotate in the reverse direction. . Since the hose 600 and the runner 3 cannot slide, the hose 600 can no longer move downwards, thus realizing hovering, so the hose 600 is balanced by the friction force of the runner 3 and the gravity of the weight 700, so the user When holding the pull-out faucet, there is no need to bear the gravity of the weight 700, so as to obtain a good use experience.

If the user needs to pull out another section of hose 600, he only needs to pull it upwards, and then the wheel 3 rotates in the forward direction, and the ball 2 moves in the opposite direction, entering the second arc segment 312 from the stop point 3121, and from the second arc segment 312 The segment 3122 cuts into the third arc segment 313 , and then cuts into the first arc segment 311 by an end 3131 of the third arc segment 313 . If there is no need to pull out again, repeat the description in the previous paragraph to achieve hovering again.

If the user wants to return the hose 600 to the initial position from the hovering state, that is, the pulling nozzle 300 is to be seated on the upper sleeve 200, the user only needs to lift the hose 600 lightly, and then let the hose 600 move down to the initial position. The location is fine. The way of movement at this time is that the hose 600 is lightly lifted, the hose 600 moves upward, the runner 3 rotates forward, and the ball 2 moves in the opposite direction, from the hovering position 3131 through the second arc segment 312 to the second arc segment The other end 3122 of 312 cuts into the third arc segment 313. At this time, the hose 600 moves downward again, and the runner 3 rotates in the reverse direction. Relatively speaking, the ball 2 moves forward, and the ball 2 is unobstructed in the third arc segment 313. ground reverse circle (because the other end 3132 groove bottom of the third arc segment is higher than the groove bottom of the third arc segment 313 cut into place, so it can circle, and because the other end 3122 groove degree of the second arc segment 312 is higher than The groove of the third arc section 313 is cut into, so it cannot retreat into the second arc section 312 when going around the position circle), until the hose 600 is retracted to the initial position.

Embodiment 2 of the hovering positioning device is shown in FIG. 7 . The main difference between it and Embodiment 1 is that on the positioning surface 310 , the ball groove only has the first arc segment 311 and the stop position 3121 . One end 3111 of the first arc segment 311 is connected to the stop position 3121 , and the first arc segment 311 is reversely rotated from the one end 3111 and then the other end 3112 reversely cuts the outside of the first arc segment 311 itself. Similarly, the groove depth of the cutting end 3112 is smaller than the groove depth of the cut section; the reverse direction is the rotation direction of the positioning surface when the pull tube or the stay rope moves downward; the forward direction is the positioning surface when the pull pipe or the stay rope moves upward turn around.

The second embodiment of the hover positioning device is mainly used for hover positioning when the pull rope or pull tube is pulled out in one direction. When the pull rope or the pull tube is pulled out in one direction, the runner 3 rotates in the forward direction, and the ball 2 moves in the reverse direction relatively, and can circle in the reverse direction in the first arc segment 311 without hindrance. If the rope or tube is retracted by accident, the runner 3 will rotate in the reverse direction, and the ball 2 will move in the forward direction relatively, and will enter the parking position 3121 from the end 3111 of the first arc segment 311, and cannot roll any more. It can no longer be rotated in the opposite direction, so that the pull tube or pull cord can be hovered.

The foregoing description describes preferred embodiments of the invention, but it should be understood that the invention is not limited to the above embodiments and should not be viewed as excluding other embodiments. Based on the enlightenment of the present invention, changes made by those skilled in the art in combination with known or prior art and knowledge should also be considered within the protection scope of the present invention.
