Description

Technical Field

[0001] The utility model relates to the technical field of water heating equipment, in particular to a lifting adjustment structure and a lifting faucet. Background Art

[0002] In existing lift faucet designs, adjusting the height of the lift tube relative to the valve body often relies on inserting an O-ring or other similar sealing element between the lift tube and the valve body. This design creates a high friction force through the tight circumferential squeezing of the O-ring, hoping to achieve stability and positioning during the lifting process. However, during the entire lifting process, the user needs to continuously overcome the high friction force generated by the squeezing of the O-ring, resulting in a heavy feel and a poor user experience. In addition, although some faucet products with lift adjustment structures already exist on the market, most of these products have problems such as complex structure and inconvenient adjustment. Utility Model Content

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background technology and to provide a lifting adjustment structure and a lifting faucet. The lifting faucet realizes the height adjustment between the lifting pipe and the valve body through a simple mechanical structure.

[0004] To achieve the above objectives, the various embodiments of the present invention adopt the following technical solutions but are not limited to the following solutions:

[0005] The first technical solution relates to a lifting and adjusting structure for adjusting the position of a first object relative to a second object along a first direction, wherein the first object is inserted into the second object along the first direction, and comprises a clamping member, which is placed in the second object and sleeved on the outside of the first object; the first object and the clamping member are limitedly matched along the first direction; an adjusting member, which is connected and matched with the second object along a second direction perpendicular to the first direction; an elastic member, which is located between the clamping member and the adjusting member along the second direction; the adjusting member is adjusted along the second direction to drive the elastic member to act on the clamping member, so that the clamping member clamps or releases the first object.

[0006] The second technical solution is based on the first technical solution, wherein the inner wall of the clamping member is provided with a contact surface at least part of which is made of elastic friction material, and the contact surface is in contact with the first object.

[0007] The third technical solution is based on the second technical solution, wherein an abutment portion is provided on the outer peripheral wall of the clamping member, one end of the elastic member abuts against the abutment portion, and the other end abuts against the adjusting member.

[0008] The fourth technical solution is based on the third technical solution, wherein the abutting portion is close to one end of the contact surface.

[0009] The fifth technical solution is based on any one of the first to fourth technical solutions, wherein a lifting faucet includes a lifting tube, a valve body and the above-mentioned lifting adjustment structure, the lifting tube is movably inserted into the adjustment hole in the valve body, and can be adjusted along the first direction of the valve body through the lifting adjustment structure, the lifting tube is a first object, and the valve body is a second object.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the valve body is provided with a mounting portion, the mounting portion is close to the top position of the valve body along the first direction, the lifting and adjusting mechanism is installed in the mounting portion, and the lifting tube is movably inserted into the mounting portion and fixed on the lifting and adjusting structure.

[0011] The seventh technical solution is based on the sixth technical solution, wherein the mounting portion is provided with a through hole along the second direction for threaded engagement with the adjusting member, and the adjusting member is installed in the through hole along the second direction and partially protrudes from the outside of the valve body.

[0012] The eighth technical solution is based on the sixth technical solution, wherein a protrusion is provided on the outer peripheral wall of the end of the clamping member away from the contact surface, and the mounting portion is provided with a groove adapted to the protrusion at a position corresponding to the protrusion.

[0013] The ninth technical solution is based on the sixth technical solution, wherein the valve body is located below the mounting portion along the first direction and is further provided with a shaft sleeve for sleeve-mounting the lifting tube, and the inner wall of the shaft sleeve is provided with a plastic material.

[0014] The tenth technical solution is based on the sixth technical solution, wherein the valve body is provided with an opening, the opening is located above the mounting portion along the first direction, and the valve body is provided with a limit member, which is installed at the opening.

[0015] From the above description of the various embodiments of the present invention, it can be seen that compared with the prior art, the various embodiments of the present invention have the following beneficial effects:

[0016] In the first technical solution and related embodiments, by rotating the adjusting member, the adjusting member can be displaced in the second direction due to its connection and fit with the second object along the second direction. This displacement is transmitted by the elastic member and converted into compression or release of the clamping member, thereby adjusting the force applied to the first object, thereby achieving lifting and lowering adjustment of the first object along the first direction. This design allows the user to flexibly adjust the position of the first object relative to the second object as needed. When adjusted to the desired position, the elastic member allows the clamping member to tightly hold the first object, forming a stable limit fit, preventing the first object from moving without external force, and ensuring the stability of the adjusted position. At the same time, the vibration-damping effect of the elastic member ensures smooth lifting and lowering of the first object, preventing it from locking or becoming excessively loose, allowing it to remain stable at any position. The entire lifting and lowering adjustment structure, consisting of the clamping member, the adjusting member, and the elastic member, has a relatively simple structure and low manufacturing cost. Furthermore, adjustment can be achieved by rotating the adjusting member, making operation simple and quick.

[0017] In the second technical solution and related embodiments, the elastic friction material has a high coefficient of friction, significantly increasing the friction between the two when in contact with the first object. The contact surface composed of the elastic friction material on the inner wall of the clamping member effectively counteracts the downward movement of the first object due to its own weight or external forces through dynamic friction, ensuring the stability and reliability of the adjustment process. Furthermore, the localized contact surface composed of the elastic friction material provides a more concentrated distribution of friction.

[0018] In the third technical solution and related embodiments, the abutment portion and the receiving groove effectively secure the elastic member between the gripping member and the adjusting member, forming a stable elastic transmission system. When the adjusting member rotates and moves in the second direction, it compresses or releases the elastic member. This compression or release force is evenly transmitted to the gripping member via the abutment portion, thereby achieving height adjustment of the first object.

[0019] In the fourth technical solution and related embodiments, positioning the abutment portion near the contact surface more effectively directs the force transmitted by the adjusting member through the elastic member to the contact surface between the clamping member and the first object, enabling the clamping member to respond more quickly to such changes. This force transmission path reduces force loss and dispersion, improving adjustment efficiency.

[0020] In the fifth technical solution and related embodiments, the built-in lift adjustment mechanism allows the user to easily adjust the height of the lift tube (i.e., the first object) relative to the valve body (i.e., the second object). This height adjustment function allows the lift faucet to adapt to different usage scenarios and needs, such as hand washing sinks and vegetable sinks, providing a more flexible and convenient user experience.

[0021] In the sixth technical solution and related embodiments, the lifting and adjusting mechanism is installed in the top mounting portion of the valve body, making the installation and replacement of the lifting and adjusting mechanism convenient and easy to maintain.

[0022] In the seventh technical solution and related embodiments, the adjusting member is threadedly mounted within the through-hole of the mounting portion, achieving a secure connection between the adjusting member and the valve body. The adjusting member partially protrudes from the exterior of the valve body, allowing the user to raise or lower the valve by simply rotating the adjusting member, improving ease of use.

[0023] In the eighth technical solution and related embodiments, the matching design of the protrusion and the groove ensures the stable position of the clamping member in the installation portion and prevents loosening or displacement during the adjustment process.

[0024] In the ninth technical solution and related embodiments, the sleeve contains plastic material, which reduces the shaking of the lifting tube during the up and down movement and improves the stability of the device. At the same time, the cushioning effect of the plastic material also reduces noise and wear.

[0025] In the tenth technical solution and related embodiments, the limit member closes the upward opening of the valve body along the first direction, and at the same time the limit member limits the upward movement range of the clamping member, further ensuring the stable position of the clamping member in the installation part.

DETAILED DESCRIPTION

[0036] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are preferred embodiments of the present invention and should not be regarded as excluding other embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] In the claims, description and the above-mentioned drawings of the present utility model, unless otherwise clearly defined, the use of terms such as "first", "second" or "third" is to distinguish different objects rather than to describe a specific order.

[0038] In the claims, specification and the above-mentioned drawings of the present utility model, unless otherwise expressly defined, directional words, such as the terms "center", "transverse", "longitudinal", "horizontal", "vertical", "top", "bottom", "inside", "outside", "up", "down", "front", "back", "left", "right", "clockwise", "counterclockwise" and the like, indicating directions or positional relationships are based on the directions and positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the specific protection scope of the present utility model.

[0039] In the claims, specification and the above drawings of the present utility model, unless otherwise clearly defined, if the terms "fixed connection" or "fixed connection" are used, they should be understood in a broad sense, that is, any connection method without any displacement relationship and relative rotation relationship between the two parties, that is to say, including non-detachable fixed connection, detachable fixed connection, integral connection and fixed connection through other devices or elements.

[0040] In the claims, description and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0041] See also Figures 1 to 7,like Figures 1 to 4 As shown, a lifting and adjusting structure is used to adjust the position of a first object relative to a second object along a first direction. The first object is inserted into the second object along the first direction. The lifting and adjusting structure includes a clamping member 10, an adjusting member 11, and an elastic member 12. The adjusting member 11 is adjusted along a second direction perpendicular to the first direction, driving the elastic member 12 to act on the clamping member 10, causing the clamping member 10 to clamp or release the first object.

[0042] The clamping member 10 is placed inside the second object and sleeved outside the first object; the first object and the clamping member 10 are limitedly matched along the first direction. Specifically, the inner wall of the clamping member 10 is provided with a contact surface at least part of which is composed of an elastic friction material 13. The contact surface is in contact with the first object, and the limited matching along the first direction (usually the vertical direction) is achieved through friction. The elastic friction material 13 has a high friction coefficient. When it contacts the first object, it can significantly increase the friction between the two. The contact surface composed of elastic friction materials 13 distributed at intervals on the inner wall of the clamping member 10 uses dynamic friction to effectively resist the downward trend of the first object due to its own weight or external force, thereby ensuring the stability and reliability of the adjustment process. The contact surface composed of elastic friction materials 13 distributed locally at intervals makes the friction distribution more concentrated and the manufacturing cost is lower.

[0043] The clamping member 10 is usually cylindrical or tubular, and its inner diameter is slightly larger than the outer diameter of the first object so that it can be easily mounted on the first object. The outer diameter of the clamping member 10 is determined according to specific design requirements, and usually takes into account the matching relationship with the mounting portion 21 inside the second object and the required strength and rigidity. The selection of elastic friction material 13 depends on the specific application scenario and requirements. Common materials include rubber, silicone, polyurethane, etc., which have good elasticity and wear resistance, and can provide good friction effect and a long service life. In this embodiment, if Figure 7 As shown, the clamping member 10 is tubular, and the elastic friction material 13 is a soft rubber pad. In addition, the outer peripheral wall of the clamping member 10 is also provided with an abutment portion 14 for interacting with the elastic member 12. The abutment portion 14 is close to one end of the contact surface. By arranging the abutment portion 14 at the end close to the contact surface, the force transmitted by the adjustment member 11 through the elastic member 12 can be more effectively applied directly to the contact surface between the clamping member 10 and the first object, and the clamping member 10 can respond to such changes more quickly. This force transmission path reduces force loss and dispersion, thereby improving the efficiency of adjustment.

[0044] Adjustment member 11, such as Figures 1 to 4As shown, it is connected to the second object in a second direction perpendicular to the first direction (e.g., horizontal direction). In this embodiment, the adjusting member 11 is threadedly connected to the second object. By rotating the adjusting member 11, the first object can be tightened or loosened in the second direction. The adjusting member 11 is provided with a receiving groove 15 for accommodating the elastic member 12. Specifically, the adjusting member 11 is an adjusting nut.

[0045] The elastic member 12 is located between the clamping member 10 and the adjusting member 11 along the second direction, with one end thereof abutting against the abutting portion 14 of the clamping member 10 and the other end abutting against the adjusting member 11. Specifically, in order to facilitate the abutment of the elastic member 12, the abutting portion 14 and the adjusting member 11 can both be receiving grooves or bosses, or one of them can be a receiving groove and the other can be a boss. In this embodiment, the abutting portion 14 is a boss, and the adjusting member 11 is provided with a receiving groove 15. When the adjusting member 11 is rotated, the elastic member 12 is compressed or released, thereby pushing the clamping member 10 to clamp or release the first object along the second direction, thereby adjusting the position of the first object. Through the abutting portion 14 and the receiving groove 15, the elastic member 12 is effectively fixed between the clamping member 10 and the adjusting member 11, forming a stable elastic transmission system. When the adjusting member 11 rotates and moves in the second direction, it compresses or releases the elastic member 12. This compression or release force is evenly transmitted to the holding member 10 via the abutment portion 14, thereby achieving the lifting and lowering adjustment of the first object. The elastic member 12 can be made of a spring or an elastic rubber pad. In this embodiment, the elastic member 12 is a spring.

[0046] In this embodiment, by rotating the adjusting member 11, the adjusting member 11 can be displaced in the second direction due to the threaded engagement with the second object along the second direction. This displacement, transmitted by the elastic member 12, is converted into compression or release of the clamping member 10, thereby adjusting the force applied to the first object, thereby achieving vertical adjustment of the first object in the first direction. This design allows the user to flexibly adjust the position of the first object relative to the second object as needed. When adjusted to the desired position, the elastic member 12 allows the clamping member 10 to tightly grip the first object, forming a stable, restrained fit, preventing the first object from moving without external forces, thereby ensuring the stability of the adjusted position. Furthermore, the vibration-damping effect of the elastic member 12 ensures smooth lifting and lowering of the first object, preventing it from locking or excessively loosening, allowing it to remain stable at any position. The entire lifting and lowering mechanism, consisting of the clamping member 10, the adjusting member 11, and the elastic member 12, is relatively simple and has low manufacturing costs. Furthermore, adjustment can be achieved simply by rotating the adjusting member 11, making operation simple and quick.

[0047] A lifting faucet, such as Figures 1 to 6As shown, it comprises a lifting pipe 1, a valve body 2, a water inlet assembly, a water outlet assembly 4, and the aforementioned lifting and adjusting structure. The valve body is provided with an adjustment hole along a first direction. The lifting pipe 1 is movably inserted into the adjustment hole in the valve body 2 and can be adjusted along the first direction of the valve body 2 via the lifting and adjusting structure. The lifting pipe 1 is the first object, and the valve body 2 is the second object. The valve body 2 is provided with a flow channel extending along the first direction, which is responsible for guiding water flow through the valve body 2. One end of the valve body 2 is connected to the water inlet assembly. One end of the lifting pipe 1 is inserted into the flow channel of the valve body 2, and the other end is connected to the water outlet assembly 4. The water inlet assembly and the water outlet assembly 4 are prior art and will not be described in detail. The lifting pipe 1 is inserted into the flow channel of the valve body 2 through the adjustment hole, and the height is adjusted by the lifting and adjusting structure. The built-in lifting and adjusting structure allows the user to easily adjust the height of the lifting pipe 1 (i.e., the first object) relative to the valve body 2 (i.e., the second object). This height adjustment function allows the lifting faucet to adapt to different usage scenarios and needs, such as hand washing sinks and vegetable washing sinks, providing a more flexible and convenient user experience.

[0048] The lifting pipe 1 is a component that allows the user to adjust the water outlet height as needed, and is usually designed to be both sturdy and lightweight for easy operation and stability. The lifting pipe 1 is usually made of corrosion-resistant and wear-resistant materials, such as stainless steel, copper alloy or high-quality plastic, to ensure reliability and durability under long-term use. The shape of the lifting pipe 1 is mostly a straight pipe or a pipe with a certain degree of curvature to adapt to different installation requirements and usage scenarios. Specific connection interfaces are designed at both ends of the lifting pipe 1 to ensure a firm connection with the valve body 2 and the water outlet assembly 4. These interfaces may include threads, buckles 17 or other forms of fastening devices to ensure that the lifting pipe 1 does not fall off or loosen during movement. In this embodiment, if Figure 1 and Figure 4 As shown, the lifting tube 1 is fastened by a buckle 17 .

[0049] The valve body 2 is the main part of the lifting faucet. The valve body 2 is usually made of high-strength, corrosion-resistant materials such as brass and stainless steel to ensure that it can withstand the impact and corrosion of water flow during long-term use. The valve body 2 includes a valve core 7, a control mechanism 8, a fixed tube 3, a shaft sleeve 5 and a limiter 6. The valve core 7 controls the on and off of the water flow and the flow rate by rotating or moving. The control mechanism 8, such as a handle or knob, allows the user to operate the valve core 7 and control the opening and closing of the water flow. The valve body 2 is connected to the main part of the faucet (such as a wall or sink) through a fixed tube 3.

[0050] The fixed tube 3 is made of high-strength, corrosion-resistant materials to ensure its stability and durability during long-term use. The shape of the fixed tube 3 is mostly a straight tube or a tube with a certain degree of curvature to adapt to different installation environments and usage requirements. One end of the fixed tube 3 is designed with a connection interface (such as a threaded interface, a flange interface, etc.) that matches the main part of the faucet so that it can be firmly installed in a predetermined position. The other end is connected to the valve body 2 to ensure smooth passage of water. In this embodiment, the fixed tube 3 is fixed in the sink using a locking nut assembly 23. The lifting tube 1 is plugged into the flow channel of the valve body 2 and into the fixed tube 3. The buckle 17 at the plug-in end of the lifting tube 1 ensures that the lifting tube 1 will not fall off from the fixed tube 3 during the lifting process.

[0051] like Figure 1 As shown, the valve body 2 is provided with a mounting portion 21. The mounting portion 21 is close to the top position of the valve body 2 along the first direction, providing an installation space for the lifting and adjusting structure. The lifting and adjusting mechanism is installed in the mounting portion 21. The lifting tube 1 is movably inserted into the mounting portion 21 and fixed to the lifting and adjusting structure. The mounting portion 21 is provided with a through hole 24 along the second direction, which is threadedly engaged with the adjusting member 11. The adjusting member 11 is installed in the through hole 24 along the second direction and partially protrudes from the outside of the valve body 2. The adjusting member 11 is installed in the through hole 24 of the mounting portion 21 by threaded engagement, thereby achieving a stable connection between the adjusting member 11 and the valve body 2. The adjusting member 11 partially protrudes from the outside of the valve body 2, allowing the user to perform lifting and adjusting directly by rotating the adjusting member 11, thereby improving the convenience of use.

[0052] A raised portion 16 is provided on the outer peripheral wall of the end of the gripping member 10 that is distal to the contact surface. A recess 22 that mates with the raised portion 16 is provided on the mounting portion 21 at a position corresponding to the raised portion 16. The mating design of the raised portion 16 and the recess 22 ensures a stable position of the gripping member 10 within the mounting portion 21, preventing loosening or shifting during adjustment. This prevents the gripping member 10 from rotating circumferentially while simultaneously pushing the gripping member 10 toward the bottom of the recess 22 to clamp the lifting tube 1.

[0053] like Figure 1 and Figure 4 As shown, the sleeve 5 is located below the mounting portion 21 along the first direction and is also provided to house the lifting tube 1. The inner wall of the sleeve 5 comprises a plastic material. This plastic material reduces the shaking of the lifting tube 1 during its vertical movement, improving the stability of the device. The cushioning effect of the plastic material also reduces noise and wear. Specifically, the sleeve 5 is mounted on the lifting tube 1 and positioned between the mounting portion 21 and the fixed tube 3.

[0054] like Figure 4As shown, the stopper 6 is mounted above the mounting portion 21 along the first direction. The valve body 2 has an opening located above the mounting portion 21 along the first direction, and the stopper 6 is mounted at the opening. The stopper 6 closes the upward opening of the valve body 2 along the first direction and limits the upward movement of the clamping member 10, further ensuring its stable position within the mounting portion 21. Specifically, the stopper 6 is a bushing.

[0055] The above description and embodiments are used to explain the scope of protection of the utility model, but do not constitute a limitation on the scope of protection of the utility model. Based on the enlightenment of the utility model or the above embodiments, modifications, equivalent replacements, or other improvements to the embodiments of the utility model or part of the technical features thereof that can be obtained by ordinary technicians in this field through logical analysis, reasoning, or limited experiments in combination with common knowledge, ordinary technical knowledge in this field and / or existing technology should be included in the scope of protection of the utility model.
