Description

Technical Field

[0001] The present application relates to the technical field of hovering positioning, and in particular to a hovering positioning component and a pull-out faucet. Background Art

[0002] In a pull-out faucet, a weight is generally provided on the pull-out hose to allow the pulled-out nozzle to automatically reset. After the user releases the pulled-out nozzle, the nozzle will automatically return to the faucet body under the action of the gravity of the weight. However, the setting of the weight will cause the user to be continuously affected by the gravity of the weight when holding the pulled-out nozzle, and a greater force is needed to hold the pulled-out nozzle, resulting in a poor user experience. Summary of the Invention

[0003] The purpose of this application is to overcome the above-mentioned defects or problems in the background technology, and to provide a hovering positioning component and a pull-out faucet. The pull-out faucet adopts the hovering positioning component, which can hover and position after the pull-out nozzle is pulled out, and is not affected by the hovering positioning function when it is put back.

[0004] To achieve the above objectives, this application adopts the following technical solutions:

[0005] ] a suspension positioning assembly, which is used to enable a retractable moving part installed in a fixed part to hover in a specific position after being pulled, comprising: a shell, an inner wall of which is provided with a linear groove and is configured to be fixed relative to the fixed part; a rotating wheel, which is rotatably mounted on the shell and has a ball groove on one end face facing the linear groove; a coil spring, whose two ends act on the shell and the rotating wheel respectively, and is used to drive the rotating wheel to rotate in a first direction; a pull rope, which is wound around the outer circumference of the rotating wheel, and one end of which extends out of the shell and is fixed to the moving part to pull the rotating wheel to rotate in a second direction opposite to the first direction when the moving part is retracted; a ball, which is simultaneously mounted in the linear groove and the ball groove, and reciprocates in the linear groove when the rotating wheel rotates; the ball groove is configured to allow the ball to roll freely in the second direction when the rotating wheel rotates in the first direction, and to roll in the first direction to a position that limits the rotating wheel from continuing to rotate when the rotating wheel rotates in the second direction so that the moving part hovers.

[0006] Furthermore, the ball groove includes an outer arc segment located on the outside, an inner arc segment located on the inside, and a stop segment located between the outer arc segment and the inner arc segment; one end of the outer arc segment is connected to the stop segment, and the other end is connected to itself along the second direction; one end of the inner arc segment is connected to the middle part of the outer arc segment, and the other end is connected to itself along the first direction; the end of the stop segment away from the outer arc segment is connected to the middle part of the inner arc segment along the second direction, and it is provided with a stop position for limiting the ball from continuing to roll along the first direction; the connecting ends in the outer arc segment, the inner arc segment and the stop segment are all higher than the connected ends.

[0007] Furthermore, the housing is provided with a rotating shaft; the rotating wheel is provided with a plug hole for plugging and cooperating with the rotating shaft so as to enable the rotating wheel to rotate relative to the housing.

[0008] Furthermore, the shell includes a first shell and a second shell that are fixed to each other and form a mounting cavity for installing the rotating wheel, coil spring, pull rope and ball; the rotating shaft and the linear groove are both arranged on a side wall of the first shell, and the extension direction of the linear groove is perpendicular to the extension direction of the rotating shaft.

[0009] Furthermore, one end of the coil spring is fixedly connected to the rotating shaft, and the other end is fixedly connected to the rotating wheel.

[0010] Furthermore, a wire winding groove is provided on the outer periphery of the rotating wheel; the pull rope is wound around the wire winding groove.

[0011] In addition, the present application also provides a pull-out faucet, which includes a faucet body, a pull-out hose, a pull-out nozzle and a weight, wherein one end of the pull-out hose is connected to the faucet body, and the other end is connected to the pull-out nozzle. The weight is installed on the pull-out hose, and it also includes a hovering positioning assembly as described in any one of the above items; the faucet body forms the fixed part, and the pull-out hose, pull-out nozzle and weight form the moving part.

[0012] Furthermore, the shell is fixedly connected to the faucet body and is located above the weight; one end of the pull rope is fixedly connected to the weight.

[0013] From the above description of the present application, it can be seen that compared with the prior art, the present application has the following beneficial effects:

[0014] 1. The hovering and positioning assembly is connected to the moving part via a pull rope, so that the movement of the moving part can drive the rotating wheel to rotate, and the moving part can be pulled by the pull rope to hover at a specific position. Compared with a structure in which the moving part is directly locked with the rotating wheel through friction, it does not require fine adjustment of the matching relationship between the moving part and the rotating wheel. There is no problem that the rotating wheel cannot make the moving part hover at a specific position due to the matching error between the moving part and the rotating wheel. There is no need to set a corresponding error compensation or adjustment structure in the hovering and positioning assembly. Therefore, the structure of the hovering and positioning assembly provided by the present application is more streamlined and the manufacturing cost is lower.

[0015] Since the pull rope is made of soft material, it can only drive the rotating wheel to rotate in one direction by being pulled, and cannot be driven to rotate in the opposite direction by being wound around the rotating wheel in the opposite direction. Therefore, in the present application, a coil spring is further provided. Through the return action of the moving part, the rotating wheel can be pulled by the pull rope to rotate in the second direction. At the same time, the coil spring stores elastic potential energy during this process. When the moving part is pulled out of the fixed part, the coil spring releases the elastic potential energy and drives the rotating wheel to rotate in the first direction.

[0016] The ball groove and the linear groove are matched with a ball that can move in the two grooves. The rotation and stop of the wheel can be controlled by the rolling and docking of the ball in the ball groove, thereby realizing the hovering positioning of the moving part.

[0017] 2. The ball groove is provided with an outer arc segment, an inner arc segment and a stop segment. When the moving part is pulled and the coil spring drives the wheel to move in the first direction, the ball moves in the second direction in the ball groove. When the wheel is pulled by the moving part to move in the second direction, the ball moves in the first direction in the ball groove. Since the connecting ends in the outer arc segment, the inner arc segment and the stop segment are all higher than the connected ends, the rolling of the ball in the second direction is smooth and cannot be stopped. When the ball rolls in the first direction, it will enter the stop position in the stop segment and jam the wheel, restricting the wheel from continuing to rotate, thereby realizing the hovering positioning of the moving part.

[0018] 3. The housing is provided with a rotating shaft, and the rotating wheel is provided with a plug hole, and the rotating shaft can be inserted into the plug hole to realize the rotating installation of the rotating wheel.

[0019] 4. A first shell and a second shell are provided, and the two cooperate with each other to form an installation cavity so that the rotating wheel, coil spring, pull rope and ball can be installed in the installation cavity. At the same time, the linear groove provided on the first shell and the extension direction of the rotating shaft are perpendicular to each other to ensure that the ball can cooperate with the ball groove and the linear groove at the same time.

[0020] 5. The two ends of the coil spring are fixed to the rotating shaft and the rotating wheel respectively, so that the coil spring stores potential energy when the rotating wheel rotates in the second direction, and drives the rotating wheel to rotate in the first direction by releasing the potential energy.

[0021] 6. A winding groove is set on the rotating wheel to allow the rope to be wound around and prevent the rope from escaping from the rotating wheel.

[0022] 7. The present application also provides a pull-out faucet, which can achieve hovering positioning after the pull-out nozzle is pulled out through the hovering positioning component provided by the present application. The user does not need to bear the pulling force of the heavy hammer when holding the pull-out nozzle, and can obtain a good user experience.

[0023] 8. The shell of the hovering positioning component is fixed to the faucet body and located above the weight, which can facilitate the installation of the pull-out faucet. One end of the pull rope is fixed to the weight to prevent the pull rope from pulling the pull-out hose of the pull-out faucet and causing deformation of the pull-out hose.

[0038] See also Figure 1 and Figure 2 , both show the structural schematic diagrams of an embodiment of a pull-out faucet provided by the present application. The pull-out faucet mainly includes a faucet body 10, a pull-out nozzle 12, a pull-out hose 14, and a weight 15. The faucet body 10 includes a handle, which is used to control the connection and disconnection of the water channel in the faucet body 10. The pull-out hose 14 is connected to a water outlet of the faucet body 10 at one end and to the pull-out nozzle 12 at the other end. The water output of the pull-out nozzle 12 can be controlled by operating the handle. At the same time, a weight 15 is provided on the pull-out hose 14 away from the pull-out nozzle 12. The weight 15 has a certain weight. A limit tube 13 is also provided on the faucet body 10. The limit tube 13 and the interior of the faucet body 10 together form a pipeline that limits the movement path of the pull-out hose 14. The end of the pull-out hose 14 passing through the pipeline is connected to the pull-out nozzle 12. The weight 15 is located below the faucet body 15. The user can pull the pull-out hose 14 out of the faucet body 10 to a certain length by holding the pull-out nozzle 12. During this process, the heavy hammer 15 will be pulled upward. When the user releases the pull-out nozzle 12, the pull-out hose 14 will retract into the faucet body 10 under the action of the heavy hammer 15, and the pull-out nozzle 12 will return to the position that cooperates with the faucet body 10.

[0039] in, Figure 1 FIG. 1 shows a schematic structural diagram of the pull-out nozzle 12 of the pull-out faucet provided in this embodiment when the pull-out nozzle 12 is in a retracted state. Figure 2 It shows a structural schematic diagram of the pull-out nozzle 12 of the pull-out faucet provided by this embodiment when it is in a pulled-out state.

[0040] The pull-out faucet also includes a hovering positioning component 20, which is used to enable the pull-out movable component installed in the fixed component to hover at a specific position after being pulled. In this embodiment, the above-mentioned fixed component is the faucet body 10 in the pull-out faucet, and the movable component is the component in the pull-out faucet composed of the pull-out nozzle 12, the pull-out hose 14 and the weight 15. Since the pull-out nozzle 12, the pull-out hose 14 and the weight 15 are connected to each other as a whole, the hovering of the weight 15 can fix the length of the pull-out hose 14.

[0041] The hovering positioning assembly 20 mainly includes a housing, a rotating wheel 24, a coil spring 25, a pull rope 21 and a ball 27, and further includes a connecting piece 26 and a plurality of fixing bolts.

[0042] The shell includes a first shell 22 and a second shell 23 which are fixed to each other and form a mounting cavity for mounting a rotating wheel 24, a coil spring 25, a pull rope 21 and a ball 27, and the inner wall of the shell is provided with a rotating shaft 221 and a linear groove 222. Specifically, the two are arranged on one side wall of the first shell 22, and the extension direction of the linear groove 222 is perpendicular to the extension direction of the rotating shaft 221.

[0043] For details, please refer to Figure 3 and Figure 4 , a circular recess is provided on each of the opposite sides of the first shell 22 and the second shell 23. When the first shell 22 and the second shell 23 are fixed together as a whole by fixing bolts, the two circular recesses can cooperate with each other to form a cylindrical installation cavity. Figure 4 A rotational axis 221 is provided in the middle of the circular recess of the first housing 22. The rotational axis 221 extends perpendicularly to the bottom wall of the circular recess. The aforementioned linear groove 222 is also provided in the bottom wall of the circular recess. The linear groove 222 extends perpendicularly to the direction in which the rotational axis 221 extends. A positioning groove 231 is provided on the bottom wall of the circular recess of the second housing 22, corresponding to the rotational axis 221. When the first and second housings 21, 22 are fixed together, the end of the rotational axis 221 is inserted into the positioning groove 231, thereby preventing deformation of the rotational axis 221 and facilitating the positioning of the rotational axis 221 during installation and fixing of the first and second housings 21, 22. More specifically, in the normal installation orientation of the hovering positioning assembly 20, i.e., when it is installed and fixed in a vertical position, the linear groove 222 extends vertically, while the rotational axis 221 extends horizontally.

[0044] In addition, an extension groove 223 is correspondingly provided on the first shell 22 and the second shell 23. One end of the extension groove 223 is connected to the circular recessed groove on the first shell 22 and the second shell 23, and the other end is connected to the outside of the shell. It is used to allow one end of the pull rope 21 to extend from the shell after the wheel 24 and the pull rope 21 are installed in the installation cavity.

[0045] The rotating wheel 24 is rotatably mounted on the housing, and a ball groove 241 is provided on the end face of one side facing the linear groove 222. A plug hole 242 is provided on the rotating wheel 24 for plugging and cooperating with the rotating shaft 221 so that it can rotate relative to the housing. A winding groove is provided on the outer periphery of the rotating wheel 24, and the winding groove is used for the pull rope 21 to be wound around the outer periphery of the rotating wheel 24.

[0046] Two ends of the coil spring 25 act on the housing and the rotating wheel 24 respectively, and are used to drive the rotating wheel 24 to rotate along the first direction.

[0047] The pull rope 21 is wound around the outer circumference of the rotating wheel 24, and one end thereof extends out of the housing and is fixed to the moving part so as to pull the rotating wheel 24 to rotate in a second direction opposite to the first direction when the moving part retracts the fixed part.

[0048] The ball 27 is fitted in both the linear groove 222 and the ball groove 241, and reciprocates in the linear groove 222 as the wheel 24 rotates. The ball groove 241 is configured to allow the ball 27 to roll freely in the second direction when the wheel 24 rotates in the first direction. When the wheel 24 rotates in the second direction, the ball 27 rolls in the first direction to a position where further rotation of the wheel 24 is restricted, allowing the moving component to hover in a specific position. It should be noted that the rolling direction of the ball 27 in the ball groove 241 is opposite to the direction of rotation of the wheel 24.

[0049] Specifically, refer to Figure 3 、 Figure 4 and Figure 5 One end of the coil spring 25 is fixed to the rotating shaft 221, and the other end is fixed to the rotating wheel 24, wherein the end surface of the rotating wheel 24 on the other side opposite to the ball groove 241 is provided with a groove for installing the coil spring 25, and the bottom wall of the groove is provided with a plurality of protrusion structures for positioning the coil spring 25. At the same time, an insertion groove is provided on the rotating shaft 221, and the end of the coil spring 25 located at the center can be inserted into the insertion groove, so that one end of the coil spring 25 is limited in the circumferential direction of the rotating shaft 221, and the end of the coil spring 25 located on the outside can cooperate with the protrusion structure provided on the rotating wheel 24, so that the end of the coil spring 25 located on the outside will move with the rotation of the rotating wheel 24. In this embodiment, when the wheel 24 moves along the second direction, the wheel 24 drives the coil spring 25 to contract and store elastic potential energy. When the force driving the wheel 24 to move along the second direction is removed, the coil spring 25 releases its stored elastic potential energy and drives the wheel 24 to move along the first direction.

[0050] Among them, reference Figure 6 ,by Figure 6 Taking the direction shown as an example, the clockwise direction is the first direction and the counterclockwise direction is the second direction. Specifically, in the pull-out faucet provided in this embodiment, when the pull-out nozzle 12 is pulled out, the wheel 24 will rotate in the first direction, and when the pull-out nozzle 12 is retracted, the wheel 24 will rotate in the second direction.

[0051] The pull rope 21 is wound in the winding groove on the outer periphery of the rotating wheel 24, and one end thereof extends from the extension groove 223 on the shell. A connecting piece 26 is fixed to the end, and the connecting piece 26 can be fixed to the heavy hammer 15 by bolts, so that the heavy hammer 15 pulls the pull rope 21 to extend while pulling the pull hose 14 to retract, thereby driving the rotating wheel 24 to rotate in the first direction. When the rotating wheel 24 is driven by the winding spring 25 to rotate in the second direction, the pull rope 21 will be rewound around the rotating wheel 24.

[0052] The ball groove 241 includes an outer arc segment 2411 located on the outside, an inner arc segment 2412 located on the inside, and a stop segment 2418 located between the outer arc segment 2411 and the inner arc segment 2412, wherein one end of the outer arc segment 2411 is connected to the stop segment 2418, and the other end is connected to itself along the second direction; one end of the inner arc segment 2412 is connected to the middle part of the outer arc segment 2411, and the other end is connected to itself along the first direction; one end of the stop segment 2418 is connected to the end of the outer arc segment 2411, and the other end away from the outer arc segment 2411 is connected to the middle part of the inner arc segment 2412 along the second direction, and it is provided with a stop position 2419 for limiting the ball 27 from continuing to roll along the first direction; and the connecting ends in the outer arc segment 2411, the inner arc segment 2412 and the stop segment 2418 are all higher than the connected ends.

[0053] Specifically, refer to Figure 6 The outer arc segment 2411 can be regarded as a circular structure with its ends staggered from each other, and one end thereof is cut to itself along the second direction, so a third cutting portion 2415 is formed between the inner and outer circles of the outer arc segment 2411. The portion of the outer arc segment 2411 located at the outer circle is the cutting end, and the portion located at the inner circle is the cut end. The groove depth at the cutting end is smaller than the groove depth at the cut end, so the ball 27 can only be cut according to the second direction. Figure 6 The arrow indicates that the ball 27 rolls along the second direction from the outer ring of the outer arc segment 2411 to the inner ring of the outer arc segment 2411. Simultaneously, the other end of the outer arc segment 2411 also intersects with the resting segment 2418 along the first direction, forming a fourth intersecting portion 2416 between the outer arc segment 2411 and the resting segment 2418. The portion on the outer arc segment 2411 is the intersecting end, and the portion on the resting segment 2418 is the intersecting end. The ball 27 can only roll from the outer arc segment 2411 to the resting segment 2418 along the first direction.

[0054] The structure of the inner arc segment 2412 is similar to that of the outer arc segment 2411, and one end thereof is cut into the middle part of the outer arc segment 2411, thereby forming a first cutting portion 2413 between the two. The part located on the inner arc segment 2412 is the cutting end, and the part located on the outer arc segment 2411 is the cut end. The ball can only roll from the inner arc segment 2412 to the outer arc segment 2411 along the second direction; the other end of the inner arc segment 2412 is cut into itself along the first direction, forming a second cutting portion 2414 between the two. The part located on the inner ring is the cutting end, and the part located on the outer ring is the cut end. The ball 27 can only roll from the inner ring of the inner arc segment 2412 to the outer ring. At the same time, one end of the docking segment 2418 is also connected to the middle part of the inner arc segment 2412, forming a fifth connecting portion 2417 between the two. The part located on the docking segment 2418 is the connecting end, and the part located on the inner arc segment 2412 is the connected end. The ball 27 can only roll from the docking segment 2418 to the inner arc segment 2412 along the second direction.

[0055] A docking position 2419 is provided on the docking section 2418. When the ball 27 rolls from the outer arc section 2411 along the first direction to the docking section 2418, it will first fall into the docking position 2419. At this time, if the wheel 24 wants to rotate along the second direction, it will be restricted by the docking position 2419, thereby causing the moving part to hover at a specific position.

[0056] When in use, the nozzle 12 is pulled out and placed in the Figure 2 The retracted state shown is the initial state, at which time the ball 27 is located at a certain position in the outer arc segment 2411, and then the user pulls out the pull-out nozzle 12. During this process, the coil spring 25 drives the wheel 24 to rotate in the first direction, and at the same time, the ball 27 rolls in the second direction. At this time, the ball 27 will not be restricted by the third cutting portion 2415, and the ball 27 can roll back and forth in the outer arc segment 2411 along the second direction; when the user needs to pull the pull-out nozzle 12 out to the desired position, the user slightly puts the pull-out nozzle 12 back, and under the action of the heavy hammer 15, the wheel 24 is pulled by the pull rope 21 to rotate in the second direction, and the ball 27 rolls in the first direction and enters the parking segment 2418 from the fourth cutting portion 2416 until it reaches the parking position 2419. When the pull-out nozzle 12 is pulled out for the next time, the ball 27 will roll from the inner arc section 2412 to the outer arc section 2411, so that the above-mentioned hovering positioning function can be repeatedly realized.

[0057] During installation, a fixing gasket 11 is fixed to the faucet body 10. The fixing gasket 11 can be fixed to the shell of the hovering positioning assembly 20 by bolts. At the same time, the hovering positioning assembly 20 is located above the heavy hammer 15. Then the pull rope 21 is pulled out of the shell and fixed to the heavy hammer 15 through the connecting piece 26.

[0058] The present application provides a hovering positioning component and a pull-out faucet using the hovering positioning component, wherein the hovering positioning component 20 is connected to the weight 15 by a pull rope 21, so that the downward movement of the weight 15 under gravity can drive the rotary wheel 24 to rotate, and the weight 15 can be pulled by the pull rope 21 to make the weight 15 hover at a specific position. Compared with the structure in which the pull-out hose 14 or the weight 15 is directly stuck with the rotary wheel 24 through friction, it does not require fine adjustment of the matching relationship between the pull-out hose 14 or the weight 15 and the rotary wheel 24, and there will be no problem that the rotary wheel 24 cannot make the weight 15 hover at a specific position due to the matching error between the pull-out hose 14 or the weight 15 and the rotary wheel 24, and there is no need to set a corresponding error compensation or adjustment structure in the hovering positioning component 20. The structure of component 20 is more streamlined and the manufacturing cost is lower; since the pull rope 21 is made of soft material, it can only drive the rotating wheel 24 to rotate in one direction by being pulled, and cannot drive the rotating wheel 24 to rotate in the opposite direction by winding it around the rotating wheel 24 in the opposite direction. Therefore, in this application, a coil spring 25 is also provided. Through the return action of the heavy hammer 15, the rotating wheel 24 can be pulled by the pull rope 21 to rotate in the second direction. At the same time, the coil spring 25 stores elastic potential energy in this process. When the pulling nozzle 12 is pulled out of the fixed component, the coil spring 25 releases the elastic potential energy and drives the rotating wheel 24 to rotate in the first direction; the ball groove 241 and the straight groove 222 are combined with a ball 27 that can move in the two grooves. The rotation and stop of the rotating wheel 24 can be controlled by the rolling and docking of the ball 27 in the ball groove 241, thereby realizing the hovering positioning of the heavy hammer 15.

[0059] More specifically, if a friction-locking method is used in the hovering positioning mechanism, that is, a friction structure that increases friction is set on the rotating structure, and the pull-out hose is in direct contact with the friction structure, the friction force is used to drive the rotating structure to rotate. Although the rotating structure can be driven to rotate directly by the up and down movement of the pull-out hose itself, this structure requires the friction structure to apply a certain pressure to the pull-out hose. Only when the pressure is sufficient can the pull-out hose overcome the gravity of the hammer and be stuck. This pressure will cause the pull-out hose to be subjected to unnecessary pressure, and then after long-term use, the pull-out hose will be damaged or leak, reducing the service life of the pull-out faucet. At the same time, this structure also requires the pull-out hose to be positioned with high precision with the rotating structure and the friction structure. Otherwise, the pull-out hose will not be subjected to sufficient pressure and will not be able to be stuck. This high-precision matching puts higher requirements on the assembly of this type of pull-out faucet, which will lead to an increase in manufacturing costs.
