Abstract
Description
Technical Field
[0001] This utility model relates to the field of bathroom technology, and in particular to a pull-out suspension mechanism and a water outlet device. Background Technology
[0002] Existing pull-out faucets have a pull-out water hose that can be pulled out by the user to spray water to a specific location. In order to reset the faucet, the pull-out water hose is usually suspended by a weight, which requires the user to continuously apply force to the pull-out water hose to keep it in the pulled-out state, causing inconvenience to the user.
[0003] To address this, related technologies have emerged that enable pull-out faucets to stop the water pipe from being pulled out. These faucets are equipped with a suspension structure that allows the water pipe to be suspended. However, the length of the water pipe that is pulled out is fixed when it is suspended, and it cannot be suspended at any position, resulting in relatively poor flexibility in the use of pull-out faucets. Utility Model Content
[0004] The purpose of this invention is to provide a pull-out suspension mechanism and a water outlet device to solve the problem of poor usability.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] In a first aspect, this utility model proposes a pull-out suspension mechanism, including a positioning component, a lifting component, a limiting component, and a resetting component. The positioning component has multiple first limiting protrusions spaced vertically along its side. A guide protrusion is connected to the same end of each first limiting protrusion. The guide protrusion has a first guide surface that slopes upwards from the bottom towards the other end of the first limiting protrusion on its side facing the first limiting protrusion. The lifting component is movably raised and lowered relative to the positioning component, and abuts against the first guide surface. The limiting component is elastically connected to the lifting component, and maintains a tendency to move away from the lifting component in the horizontal direction. The resetting component is connected to the lifting component, and is configured to maintain a downward trend in the lifting component. When the lifting component rises relative to the positioning component, the limiting component can engage above the first limiting protrusion to restrict the lifting component from moving downwards from the first limiting protrusion, and the lifting component can translate along the first guide surface to misalign the first limiting protrusion with the limiting component.
[0007] Optionally, the reset member is also configured to maintain the tendency of the lifting member to move in the direction of the guide protrusion.
[0008] Optionally, the lifting member is provided with the first limiting protrusion on both sides that are arranged opposite each other in the horizontal direction, and the limiting member is provided on both opposite sides of the lifting member.
[0009] Optionally, the lifting member has a mounting hole, an elastic element is provided in the mounting hole, and the limiting member is movably disposed in the mounting hole and connected to the elastic element to extend or retract from the mounting hole.
[0010] Optionally, a locking element is threaded into the mounting hole. The locking element is sleeved on the limiting element and slidably connected to the limiting element to prevent the limiting element from disengaging from the lifting element.
[0011] Optionally, a second limiting protrusion is provided on the positioning member above the first limiting protrusion, the second limiting protrusion is connected to the first limiting protrusion, and the protrusion height of the second limiting protrusion is higher than the protrusion height of the first limiting protrusion.
[0012] Secondly, this utility model proposes a water outlet device, which includes the pull-out suspension mechanism described in any of the above claims, and also includes a water outlet head and a pull-out water pipe. The lifting component is connected to the pull-out water pipe, and the water outlet head is disposed at the water outlet end of the pull-out water pipe.
[0013] Optionally, the positioning element adopts a box-shaped structure, and the positioning element is at least partially embedded in the wall.
[0014] Optionally, one end of the pull-out water pipe is fixedly connected to the positioning member, the pull-out water pipe is configured as U-shaped or V-shaped, and the lifting member is slidably sleeved on the pull-out water pipe.
[0015] Optionally, the water outlet device further includes a fixing sleeve, which is fixed to the positioning member, and the water outlet head is movably inserted into the fixing sleeve and circumferentially limited by the fixing sleeve.
[0016] The beneficial effects of this utility model are as follows: The pull-out suspension mechanism and the water outlet device using it in this utility model, by setting multiple first limiting protrusions at intervals along the vertical direction on the positioning member and setting a movable member on the lifting member, when the water outlet pipe is pulled outward, the lifting member can move upward relative to the positioning member. With the cooperation of the first limiting protrusions and the movable member, the lifting member can be locked to the positioning member in one direction, thereby restricting the position of the pull-out water outlet pipe and the water outlet head connected to the pull-out water outlet pipe. Since multiple first limiting protrusions are set, the water outlet head can achieve multi-level suspension, making it more flexible to use. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0036] refer to Figures 1-8 As shown, an embodiment of this utility model proposes a pull-out suspension mechanism, which can be used in water dispensing devices including but not limited to pull-out faucets, and can also be used in other devices that require a pull-out suspension function. An embodiment of this utility model also proposes a water dispensing device, including a pull-out suspension mechanism, a pull-out water pipe 20, and a water outlet 10. The water outlet 10 is located at the water outlet end of the pull-out water pipe 20. When using the water dispensing device, the position of the water outlet 10 can be adjusted by pulling out the water outlet 10. After releasing the water outlet 10, the pull-out suspension mechanism can achieve suspension of the water outlet 10 by restricting the pull-out water pipe 20. The following describes the pull-out suspension mechanism and the water dispensing device in detail, taking the application of the pull-out suspension mechanism to a water dispensing device as an example.
[0037] refer to Figure 3As shown, the pull-out suspension mechanism includes a positioning component 1, a lifting component 2, and a limiting component 3. The positioning component 1 can be configured as a box-shaped or sleeve-shaped hollow structure, or as a plate-shaped structure. Multiple first limiting protrusions 11 are arranged at intervals along the vertical direction on the positioning component 1. The lifting component 2 can be connected to the pull-out water pipe 20 and rises relative to the positioning component 1 when the pull-out water pipe 20 is pulled out. The limiting component 3 is elastically connected to the lifting component 2 and maintains a tendency to move away from the lifting component 2 in the horizontal direction. When the lifting component 2 rises relative to the positioning component 1, the limiting component 3 can be locked above the first limiting protrusions 11 to restrict the lifting component 2 from moving below the first limiting protrusions 11. That is to say, the lifting component 2 is locked to the positioning component 1 in one direction. It is worth emphasizing that, in order to enable the water outlet 10 to return to its initial position, the positioning member 1 is also provided with a guide protrusion 12. The pull-and-hover mechanism also includes a reset member 5. The guide protrusion 12 is connected to the same end of each of the first limiting protrusions 11. The side of the guide protrusion 12 facing the first limiting protrusion 11 has a first guide surface 121 that is inclined from bottom to top toward the other end of the first limiting protrusion 11. The lifting member 2 abuts against the first guide surface 121 so that it can translate along the first guide surface 121 when the lifting member 2 rises relative to the positioning member 1, thereby gradually displacing the first limiting protrusion 11 from the limiting member 3. The reset member 5 is connected to the lifting member 2 and is configured to keep the lifting member 2 moving downward toward the positioning member 1, so that when the first limiting protrusion 11 and the limiting member 3 are displacing, it returns to the bottom of the positioning member 1, thereby returning the water outlet 10 connected to the pull-out water pipe 20 to its initial position.
[0038] In actual use, initially, both the lifting component 2 and the limiting component 3 are located below the first limiting protrusion 11, and the water outlet 10 is in its initial position. When the water outlet pipe 20 is pulled outward, the lifting component 2 moves upward relative to the positioning component 1. Under the guidance of the first guide protrusion 12, the limiting component 3 moves towards the lifting component 2, thereby avoiding the first limiting protrusion 11 and moving above the first limiting protrusion 11. At this time, if the pulling force is removed, the limiting component 3 moves away from the lifting component 2 under the action of elasticity and is limited to above the first limiting protrusion 11, thus suspending the water outlet 10. If the pulling force is continuously applied, the limiting component 3 continues to move upward relative to the positioning component 1 with the lifting component 2. Since multiple first limiting protrusions 11 are provided, the water outlet pipe 20 can be suspended at any position, making it flexible to use. When the water outlet 10 needs to return to its initial state, the limiting member 3 moves upward relative to the positioning member 1 along with the lifting member 2. Under the guidance of the first guide surface 121, the limiting member 3 translates relative to the first limiting protrusion 11 until it is misaligned with the first limiting protrusion 11, that is, the vertical projection of the limiting member 3 does not fall on the first limiting protrusion 11. At this time, the position of the limiting member 3 is defined as the unlocking position a. It can be understood that the misalignment between the limiting member 3 and the first limiting protrusion 11 is gradually carried out as the limiting member 3 rises. When the limiting member 3 is in the unlocking position a, the first limiting protrusion 11 loses its limiting effect on the limiting member 3, and then moves downward to the positioning member 1 under the action of the reset member 5, and the water outlet 10 returns to its initial position.
[0039] Specifically, to enable the repeated use of the aforementioned pull-out suspension mechanism, the reset member 5 is also configured to maintain the lifting member 2's tendency to move towards the guide protrusion 12. When the limiting member 3 is in the unlocked position a, under the action of the reset member 5, the lifting member 2 not only moves downwards but also moves towards the guide protrusion 12, thereby returning the lifting member 2 to its initial position. At this time, the position of the limiting member 3 is defined as the locked position b, and the vertical projection of the limiting member 3 falls on the first limiting protrusion 11. When the lifting member 2 rises again, the first limiting protrusion 11 can continue to play a one-way locking role on the limiting member 3. Obviously, the line connecting the locked position b and the unlocked position a is the movement trajectory of the limiting member 3, and this movement trajectory is parallel to the first guide surface 121.
[0040] refer to Figure 4 , Figure 5 and Figure 7As shown, in one embodiment, in order for the limiting member 3 to pass over the first limiting protrusion 11 and be engaged above the first limiting protrusion 11, a second guide surface 111 is provided at the bottom of the first limiting protrusion 11. The second guide surface 111 gradually approaches the lifting member 2 from bottom to top. When the limiting member 3 abuts against the second guide surface 111, under the guidance of the second guide surface 111, the limiting member 3 gradually moves towards the lifting member 2 and passes over the first limiting protrusion 11. Specifically, the first limiting protrusion 11 is set in a tooth shape, and multiple first limiting protrusions 11 are arranged from bottom to top to form a right-angled trapezoid.
[0041] In other embodiments, a third guide surface may be provided on the limiting member 3, gradually moving away from the first limiting protrusion 11 from bottom to top, so that when the third guide surface of the limiting member 3 abuts against the first limiting protrusion 11, the limiting member 3 gradually retracts towards the lifting member 2 and passes over the first limiting protrusion 11. It is understood that the second guide surface 111 and the third guide surface may be provided simultaneously.
[0042] More specifically, to improve the stability of the lifting member 2 moving upward relative to the positioning member 1, first limiting protrusions 11 are provided on both sides of the lifting member 2 that are arranged opposite each other in the horizontal direction. Correspondingly, limiting members 3 are provided on both sides of the lifting member 2, and the limiting members 3 located on the opposite sides of the lifting member 2 can respectively engage with the first limiting protrusions 11 on both sides to limit the lifting member 2. It can be understood that, corresponding to the sleeve-shaped or box-shaped positioning member 1, the first limiting protrusions 11 are provided on the two side walls of the positioning member 1 that are arranged opposite each other in the horizontal direction. Corresponding to the plate-shaped positioning member 1, the lifting member 2 has positioning members 1 on both sides of its opposite sides.
[0043] refer to Figures 4-6 As shown, in one embodiment, the height of both ends of the pull-out water pipe 20 is higher than that of the lifting member 2, i.e., the pull-out water pipe 20 is U-shaped or V-shaped, with both its inlet and outlet ends higher than the lifting member 2, and the lifting member 2 is sleeved on the pull-out water pipe 20. In this case, the moving distance of the outlet end of the pull-out water pipe 20 is equal to half the moving distance of the lifting member 2. Under the premise that the maximum stroke of the pull-out water pipe 20 remains unchanged, the minimum height dimension of the positioning member 1 is reduced, which is beneficial to reducing the volume of the entire water outlet device.
[0044] It is worth emphasizing that, in order to enable the lifting component 2 to move upward relative to the positioning component 1 when the water outlet pipe 20 is pulled out, and to ensure that the movement of the lifting component 2 under the guidance of the first guide surface 121 does not affect the position of the water outlet pipe 20, the lifting component 2 is movably sleeved on the water outlet pipe 20. At this time, the limiting component 3 is radially movable on the lifting component 2.
[0045] It is understandable that the limiting member 3 is elastically connected to the lifting member 2. This elasticity can come from the limiting member 3 itself; for example, the limiting member 3 may be made of an elastic material, or the limiting member 3 may be connected to the lifting member 2 via an elastic member 4. Specifically, refer to... Figure 4 , Figure 5 and Figure 8 As shown, the lifting component 2 has a mounting hole 21. The limiting component 3 is movably disposed in the mounting hole 21 and connected to the elastic component 4 located inside the mounting hole 21. Under the action of the elastic component 4, the limiting component 3 maintains the tendency to extend out of the mounting hole 21, that is, to move towards the first limiting protrusion 11. Under the action of the first limiting protrusion 11, the limiting component 3 retracts into the mounting hole 21.
[0046] The limiting component 3 is prone to wear after long-term use. To facilitate replacement later, the limiting component 3 is detachably mounted on the lifting component 2. Specifically, the pull-out suspension mechanism also includes a locking component 6, which is inserted into the mounting hole 21 and threadedly connected to the lifting component 2. The locking component 6 is sleeved on the limiting component 3 and slidably connected to it. The limiting component 3 adopts a T-shaped structure to prevent it from disengaging from the locking component 6, thereby preventing it from disengaging from the lifting component 2. More specifically, one of the limiting component 3 and the locking component 6 is provided with a guide groove extending radially along the lifting component 2, and the other is provided with a guide block disposed within the guide groove to restrict the rotation of the limiting component 3 relative to the locking component 6.
[0047] For example, the locking member 6 is provided with a plurality of guide grooves spaced apart along the circumference, the guide grooves penetrate the locking member 6 at both ends along the axial direction, and the plurality of guide blocks are correspondingly provided on the circumference of the limiting member 3.
[0048] In one embodiment, the reset member 5 is a tension spring, with one end connected to the lifting member 2 and the other end connected to a connecting post at the bottom of the positioning member 1. It is understood that when the water pipe 20 is pulled out to its initial position, the tension spring is in a vertical state. As the lifting member 2 moves upward relative to the positioning member 1, under the guidance of the guide protrusion 12, the lifting member 2 translates, and the tension spring gradually tilts, so that after the first limiting protrusion 11 loses its limiting effect on the limiting member 3, it applies a force to the lifting member 2 moving in the direction of the guide protrusion 12.
[0049] refer to Figure 3As shown, to prevent further pulling force from being applied to the pull-out water pipe 20 after the lifting member 2 moves above the uppermost first limiting protrusion 11, a second limiting protrusion 13 is also provided on the positioning member 1 above the first limiting protrusion 11. The second limiting protrusion 13 is connected to the first limiting protrusion 11, and the height of the second limiting protrusion 13 protruding from the surface of the positioning member 1 (hereinafter referred to as the protrusion height) is higher than the protrusion height of the first limiting protrusion 11. The second limiting protrusion 13 restricts the lifting member 2 from continuing to move upward relative to the positioning member 1. When the lifting member 2 abuts against the second limiting protrusion 13, it indicates that the pull-out water pipe 20 has been pulled to its limit.
[0050] In one embodiment, the positioning element 1 is a pre-embedded box at least partially embedded in the wall. Specifically, the positioning element 1 includes a box body and a box cover connected by bolts, which together form a cavity for accommodating the pull-out water pipe 20, the lifting element 2, and the limiting element 3. The positioning element 1 has an inlet opening and an outlet opening. The side of the positioning element 1 with the inlet opening is a panel, and the side opposite the panel is a back plate. The panel protrudes from the wall, while the back plate is located inside the wall. The pull-out water pipe 20 is disposed within the positioning element 1 and connected to an external water inlet pipe through the inlet opening, and connected to a water outlet 10 through the outlet opening. The water outlet device also includes a switch valve 30, which controls the connection between the pull-out water pipe 20 and the external water inlet pipe. The positioning element 1 also has a clearance opening for the handle of the switch valve 30 to protrude, which is also located on the panel. Based on this, a first limiting protrusion 11 is provided on the panel and / or the back plate.
[0051] Specifically, in order to keep the water outlet head 10 in the initial state stable, the water outlet device also includes a fixing sleeve 40, which is fixed to the water outlet opening and perpendicular to the panel. The water outlet head 10 in the initial state is partially inserted into the fixing sleeve 40 and is circumferentially limited by the fixing sleeve 40, thereby preventing the water outlet head 10 from rotating.
[0052] In one embodiment, the external water inlet pipe includes a hot water inlet pipe and a cold water inlet pipe to adjust the temperature of the water output according to demand. For the water outlet 10, a faucet or shower head can be selected according to actual usage needs; no specific limitation is made here.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
