In this embodiment, the rotating wheel 3 includes a positioning wheel 31 and a friction sleeve 32, and the positioning wheel 31 is further provided with a positioning surface 310. The locating surface 310 faces the linear slot 114. The friction sleeve 32 is sleeved on the revolution surface of the positioning wheel 31 and connected with the positioning wheel 31 through a spline. Through setting up friction sleeve 32, increase frictional force, make the difficult emergence slip between runner 3 and trombone slide or stay cord. The positioning wheel 31 and the friction sleeve 32 are connected through splines, so that relative rotation between the positioning wheel and the friction sleeve is avoided. The positioning surface is provided with a ball groove, the ball 2 is respectively matched with the linear groove 114 and the ball groove on the positioning surface 310, and the pull tube or the pull rope is lifted to drive the rotating wheel 3 to rotate and drive the ball 2 to linearly move in the linear groove 114.
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 section 312 is provided with a stop 3121, and the other end 3122 of the second arc section 312 is reversely cut and connected with the outer side of the third arc section 313 after reversely rotating from the stop 3121.
An end 3111 of first arc 311 is tangent to the outside of second arc 312 and thereby connects to docking station 3121. The first arc segment 311 is reversely rotated from the one end 3111 and then the other end 3112 is reversely cut outside the first arc segment 311 itself.
One end 3131 of the third arc segment 313 is reversely cut to the inner side of the first arc segment 3131, and the other end 3132 of the third arc segment 313 is forwardly cut to the inner side of the third arc segment 313 itself after the third arc segment 313 is forwardly rotated from the above-mentioned one end 3131.
And the groove depth of each cutting end is less than that of the section to be cut; the reverse direction is the rotating direction of the positioning surface when the pull pipe or the pull rope moves downwards; the forward direction is the rotation direction of the positioning surface when the pull pipe or the pull rope moves upwards.
The embodiment of the hovering locating device is used for a pull-out type tap, that is, as shown in fig. 8, the embodiment of the pull-out type tap comprises a tap body 100, an upper sleeve 200 rotatably installed on the tap body 100, a lower sleeve 400 fixedly connected with the tap body 100, an embodiment one 500 of the hovering locating device, and a hose 600 sequentially penetrating through the upper sleeve 200, the tap body 100, the lower sleeve 400 and the hovering locating device 500 and then connected with a water inlet pipe, wherein the other end of the hose 600 is connected with a pulling water nozzle 300. Under the hovering positioning device 500, the hose 600 is further fixedly connected with a weight 700.
The user can adjust the horizontal position of the idler wheel 4 by adjusting the screwing-in depth of the adjusting screw 7 so as to reduce or increase the pressure of the idler wheel 4 on the pull pipe or the pull rope, thereby enabling the hose 600 and the rotating wheel 3 to roll relatively.
The user pulls out the hose 600 by pulling out the pull-out nozzle 300, and the runner 3 rotates clockwise, and the ball 2 moves reversely relatively. If the ball 2 is initially located at the third arc segment 313, the ball 2 will cut into the first arc end 311 from one end 3131 of the third arc end 313 after moving in the reverse direction, and can rotate in the reverse direction in the first arc segment 311 without being obstructed.
If the user does not need to pull out the hose 600 any more, the hose 600 is retracted slightly and moves downwards, and the wheel 3 rotates in the opposite direction, and the balls 2 move in the opposite direction. At this time, the ball 2 will cut into the second arc segment 312 from the end 3111 of the first arc segment 311 and continue to move reversely to the stop point 3121, and at this time, the ball 2 cannot move forward any more, and therefore the wheel 3 cannot rotate reversely any more. Because the hose 600 and the rotating wheel 3 can not slide, the hose 600 can not move downwards any more, so that hovering is realized, the hose 600 is balanced by the friction force of the rotating wheel 3 and the gravity of the heavy hammer 700, and a user does not need to bear the gravity of the heavy hammer 700 when holding the drawing water nozzle, so that good use experience is obtained.
If the user needs to pull out a section of hose 600 again, only need to pull up, the rotating wheel 3 rotates in the forward direction, and relatively speaking, the ball 2 moves in the reverse direction, enters the second arc section 312 from the stop point 3121, cuts into the third arc section 313 from the second arc section 3122, and cuts into the first arc section 311 from one end 3131 of the third arc section 313. If no more pull-out is needed, the description in the previous paragraph is repeated to realize hovering again.
If the user wants to retract the hose 600 to the initial position from the hovering state, that is, if the drawing nozzle 300 is to be seated on the upper sleeve 200, the user only needs to lift the hose 600 slightly and then move the hose 600 downward to the initial position. The movement is that the hose 600 is lifted, the hose 600 moves upwards, the rotating wheel 3 rotates in a forward direction, the ball 2 moves in a reverse direction relatively, and passes through the second arc section 312 from the hovering position 3131 to the other end 3122 of the second arc section 312 and cuts into the third arc section 313, at this time, the hose 600 moves downwards again, the rotating wheel 3 rotates in a reverse direction, and relatively, the ball 2 moves in a forward direction, and the ball 2 winds in the third arc section 313 in a reverse direction without hindrance (since the groove bottom of the other end 3132 of the third arc section is higher than the groove bottom of the third arc section 313, winding is possible, and since the groove degree of the other end 3122 of the second arc section 312 is higher than the groove degree of the third arc section 313, winding cannot be performed into the second arc section 312), until the hose 600 is retracted to the initial position.
The second embodiment of the hover positioning device is shown in fig. 7. The main difference from the first embodiment is that on the positioning surface 310, the ball groove has only the first arc segment 311 and the rest position 3121. One end 3111 of the first arc segment 311 is connected to the stop 3121, and the other end 3112 of the first arc segment 311 is reversely cut off the outer side of the first arc segment 311 itself after the one end 3111 is reversely rotated. Similarly, the groove depth of the cut-and-join end 3112 is less than that of the cut-and-join section; the reverse direction is the rotating direction of the positioning surface when the pull pipe or the pull rope moves downwards; the forward direction is the rotation direction of the positioning surface when the pull pipe or the pull rope moves upwards.
The second embodiment of the hovering and positioning device is mainly used for hovering and positioning when the pull rope or the pull pipe is pulled out in a single direction. When the pull rope or the pull pipe is pulled out in one direction, the rotating wheel 3 rotates in the forward direction, and the ball 2 moves in the reverse direction relatively, so that the first arc section 311 can wind in the reverse direction without obstruction. If the pull rope or pull pipe retracts accidentally, the rotating wheel 3 rotates reversely, and the rolling balls 2 move forward relatively, and enter the parking positions 3121 from the end 3111 of the first arc segment 311, and cannot roll any more, so that the rotating wheel 3 cannot rotate reversely any more, and the pull pipe or pull pipe is suspended.
The above 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. Modifications based on the prior art or knowledge known to those skilled in the art in light of the teachings of the present invention should also be considered within the scope of the present invention.
