Description

Technical Field

[0001] The present application relates to the field of bathroom products, and in particular to a faucet. Background Art

[0002] Faucets are a common product in everyday life, particularly those used on sinks. Existing faucets generally consist of a body, a raised ring fixed to the lower end of the body, and an externally threaded sleeve coaxially fixed to the inner wall of the raised ring, with a nut threaded onto the sleeve. During installation, the lower end of the sleeve is passed through the sink until the raised ring contacts the upper surface of the sink, restricting further downward movement of the body and completing pre-installation. The nut is then tightened from the lower surface of the sink, locking the raised ring and nut to the sink, securing the faucet.

[0003] Regarding the above-mentioned related technologies, during installation, one needs to hold the faucet above the sink with one hand, and then squat under the sink to tighten the nuts under the sink with tools such as wrenches. Since the sink is generally installed close to the wall, the space is limited, the light is poor, and the wrench is not easy to rotate with the nut, the installation of the faucet is more troublesome, so it needs to be improved. Summary of the Invention

[0004] In order to reduce the space limitation for installing the faucet and facilitate the installation of the faucet, the present application provides a faucet.

[0005] The faucet provided in this application adopts the following technical solution:

[0006] A faucet comprises a main body; a plug-in part, the plug-in part being arranged at a position of the main body close to the connection with the washbasin, the interior of the plug-in part being a cavity and communicating with the interior of the main body; a limiting part, the limiting part being fixed to the outside of the plug-in part, the limiting part abutting against the washbasin countertop; a sliding part, the sliding part being slidably connected to the plug-in part, the sliding part sliding along the height direction; an elastic pin assembly, the elastic pin assembly being arranged on the inner wall of the sliding part, the elastic pin assembly being clamped to the lower surface of the washbasin when the sliding part slides downward, and the elastic pin assembly being used to limit the sliding part from sliding upward; and a tensioning assembly, the tensioning assembly being arranged at a position where the main body is located above the washbasin countertop, the tensioning assembly being used to tension the sliding part and the elastic pin assembly upward along the height direction.

[0007] By adopting the above technical solution, during installation, the main body and the plug-in part can be directly inserted downward into the wash basin until the limiting part contacts the wash basin table surface. At this time, the limiting part can limit the main body and the plug-in part from continuing to move downward; then move the sliding part downward until the elastic pin assembly is engaged with the lower surface of the wash basin; finally, the sliding part and the elastic pin assembly are tightened upward by the tightening assembly. At this time, the limiting part and the elastic pin assembly clamp the main body on the wash basin. During this process, it is only necessary to operate above the wash basin table surface, and there is no need to squat under the wash basin. The light is better and there is no space restriction. Especially in an environment where the space under the wash basin is more severely restricted, the operation is more convenient, and the faucet is easy to install.

[0008] Preferably, the main body and the side walls of the plug-in part are both provided with strip holes, and the strip holes are arranged along the height direction. An operating part extending out of the strip hole is fixed on the sliding part, and the tightening assembly is used to tighten the operating part upward. One end of the elastic pin assembly passes through the strip hole of the plug-in part and is clamped to the lower surface of the washbasin.

[0009] By adopting the above technical solution, the operating part can be connected to the sliding part through the strip hole, so that the sliding part can be driven up and down by the operating part from above the washbasin table; and one end of the elastic pin assembly can pass through the strip hole of the plug-in part after being not restricted by the thickness of the washbasin perforation.

[0010] Preferably, the operating portion and the sliding portion are detachably connected.

[0011] By adopting the above technical solution, the operating part and the sliding part are detachably connected. After the sliding part is slidably installed in the plug-in part, the operating part and the sliding part can be installed and fixed, which facilitates the installation of the sliding part in the plug-in part.

[0012] Preferably, the tensioning assembly includes a connecting block, a stud passing through the connecting block and a handle fixed to the upper end of the stud. The connecting block is provided with a through hole for the stud to pass directly through. The connecting block is fixed to the outside of the main body and is located above the strip hole. The stud is threadedly connected to the operating part, and the handle abuts against the upper side of the connecting block.

[0013] By adopting the above technical solution, after the elastic pin assembly is clamped on the lower surface of the washbasin, the stud can be passed through the connecting block, and the lower end of the stud can be threadedly connected to the operating part. When the handle abuts against the upper side of the connecting block, the stud continues to be rotated. Since the stud cannot continue to move, the stud can pull the operating part upward, thereby simultaneously pulling the moving part and the elastic pin assembly upward.

[0014] Preferably, a clamping nut is threaded onto the stud, and the clamping nut abuts against the lower side of the operating portion.

[0015] By adopting the above technical solution, when the handle is turned and the operating part is tightened, the clamping nut can be rotated so that the clamping nut abuts against the lower side of the operating part, so that the stud can remain stable and the distance between the operating part and the connecting block is further shortened, thereby improving the tightening stability of the tightening assembly on the operating part.

[0016] Preferably, the plug-in portion has a cylindrical cavity inside, the sliding portion is a ring sleeve, and the ring sleeve fits in the cylindrical cavity.

[0017] By adopting the above technical solution, through the cooperation between the cylindrical cavity and the ring sleeve, the sliding part can stably slide along the height direction of the cavity of the plug-in part.

[0018] Preferably, a circular groove is provided on the outside of the ring sleeve, and the elastic pin assembly includes a spring fixed in the circular groove and a bayonet fixed at one end of the spring away from the bottom of the circular groove. When the spring is in a natural state, one end of the bayonet is located outside the notch of the circular groove and abuts against the lower surface of the washbasin, and the other end of the bayonet is located in the circular groove.

[0019] By adopting the above technical solution, since a hole for the plug-in part to be inserted needs to be opened on the washbasin, when the plug-in part moves downward from the height direction of the hole wall of the washbasin, the pin is first restricted by the thickness of the hole wall, so the spring is compressed and the pin is completely located in the circular groove notch; when the sliding part continues to move downward and is not restricted by the hole wall, the restoring force of the spring drives one end of the pin to extend out of the circular groove notch and clamped to the lower surface of the washbasin, thereby realizing the clamping of the elastic clamping part on the lower surface of the washbasin to limit the sliding part from sliding upward.

[0020] Preferably, a flat surface is provided on the upper side of the latch, and the flat surface fits against the lower surface of the wash basin.

[0021] By adopting the above technical solution, when the movable part is pulled upward, the flat part of the pin can fit tightly against the lower surface of the washbasin, thereby increasing the clamping area between the pin and the lower surface of the washbasin and ensuring the installation stability of the faucet.

[0022] Preferably, the limiting portion is ring-shaped and is arranged around the circumference of the plug-in portion. A sealing ring is embedded in the side of the limiting portion that is in contact with the wash basin, and the sealing ring is sleeved on the outside of the plug-in portion.

[0023] By adopting the above technical solution, when the plug-in part is plugged downward into the countertop of the washbasin until the limiting part abuts against the countertop of the washbasin, the sealing ring can be squeezed, thereby ensuring the seal between the limiting part and the countertop of the washbasin and reducing water seepage from the gap between the washbasin and the plug-in part.

[0024] Preferably, the tensioning assembly and the strip-shaped hole are located on the back side of the body.

[0025] By adopting the above technical solution, the tensioning assembly and the strip hole are arranged on the back side of the main body, so that when using the faucet, the risk of hands bumping into the tensioning assembly can be reduced; at the same time, the main body can block the tensioning assembly on the back side of the main body to ensure the aesthetics of the faucet.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] (1) By arranging the coordination between the main body, the plug-in part, the sliding part, the elastic pin assembly and the tensioning assembly, the main body only needs to be fixed above the wash basin, thereby reducing the restrictions of space and light and achieving the effect of faucet installation being convenient;

[0028] (2) The tensioning assembly includes a connecting block, a stud and a handle, which can be used to tighten the sliding part and the elastic pin assembly upward from above the wash basin, making the operation convenient and quick;

[0029] (2) By providing the flat portion, the area of ​​the latch fitting the lower surface of the wash basin can be increased, thereby improving the stability of the limit portion and the latch clamping on the wash basin. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-4 This application is further described in detail.

[0036] The embodiment of the present application discloses a faucet, which is mainly suitable for use in wash basins. Figure 1 and Figure 2 The faucet includes a body 1, a plug-in part 2, a limiting part 3, a sliding part 4, an elastic pin assembly 5 and a tensioning assembly 6.

[0037] The lower end of the main body 1 is fixed to the washbasin. The position where the lower end of the main body 1 is connected to the washbasin is cylindrical, and the front side of the main body 1 is the water outlet side of the faucet, and the back side of the main body 1 is opposite to the front side. The plug-in part 2 is coaxial and fixed to the lower end of the main body 1, so that the plug-in part 2 is located near the position where the main body 1 is connected to the washbasin; the plug-in part 2 is also cylindrical, and the plug-in part 2 has a cylindrical cavity inside and is connected to the inside of the main body 1. A reserved hole is reserved on the washbasin for the plug-in part 2 to pass vertically downward. The limiting part 3 is ring-shaped, and the limiting part 3 is welded and fixed to the outside of the plug-in. The limiting part 3 is located at the position where the plug-in part 2 is close to the main body 1. The outer diameter of the limiting ring is larger than the outer diameter of the plug-in part 2. When the plug-in part 2 is gradually inserted downward into the reserved hole of the washbasin, the lower surface of the limiting part 3 abuts against the washbasin countertop, thereby limiting the plug-in part 2 and the main body 1 from continuing to move downward.

[0038] Among them, reference Figure 3 and Figure 4 A circular sealing ring 7 is embedded in the side where the limiting part 3 is in contact with the wash basin. The sealing ring 7 is sleeved on the outside of the plug-in part 2. The lower side of the sealing ring 7 is tightly fitted with the wash basin surface. The sealing ring 7 can improve the sealing between the limiting part 3 and the wash basin surface and reduce the water seepage from the gap between the plug-in part 2 and the reserved hole.

[0039] The sliding portion 4 is a ring sleeve that is slidably connected within the cavity of the plug-in portion 2. The sliding portion 4 slides in the height direction, and the outer wall of the ring sleeve fits against the inner wall of the cylindrical cavity of the plug-in portion 2, ensuring stable sliding of the sliding portion 4 in the height direction within the plug-in portion 2. A strip hole 8 is vertically opened on the back side of the main body 1 near the limit portion 3. An operating portion 9 is detachably fixed to the upper end of the sliding portion 4; the operating portion 9 includes a flat plate 91 and a screw rod 92. The flat plate 91 is rectangular and horizontally arranged. One end of the screw rod 92 is fixed to the middle position of the end of the flat plate 91 near the main body 1; the flat plate 91 is completely outside the main body 1, and one end of the screw rod 92 passes through the strip hole 8 and is fixedly connected to the upper end of the sliding portion 4 by a thread, thereby achieving a detachable connection between the sliding portion 4 and the operating portion 9.

[0040] The operating part 9 can be used to drive the sliding part 4 to move up and down from the upper surface of the wash basin. At this time, the screw 92 slides along the length direction of the strip hole 8, which also makes the sliding part 4 relatively stationary in the circumferential direction of the plug-in part 2, ensuring that the sliding part 4 can only slide along its own axial direction.

[0041] The elastic pin assembly 5 is positioned at the lower end of the sliding portion 4. A strip hole 8 is also formed in the sidewall of the plug-in portion 2. The strip hole 8 on the main body 1 and the strip hole 8 on the plug-in portion 2 are aligned in the same vertical direction. A circular groove 10 is formed on the outside of the annular sleeve. The circular groove 10 can be formed by fixing a circular cylinder horizontally on the inner wall of the annular sleeve. The circular cylinder has an open end, and the inner cavity of the circular cylinder is the circular groove 10. The notch of the circular groove 10 is the opening of the circular cylinder and is located on the outer wall of the annular sleeve. The elastic pin assembly 5 includes a spring 51 with one end fixed to the bottom of the circular groove 10 and a latch 52 fixed to the end of the spring 51 away from the bottom of the circular groove 10. When the spring 51 is in a natural state, one end of the latch 52 is located outside the notch of the circular groove 10 and abuts the lower surface of the sink, while the other end of the latch 52 is located inside the circular groove 10. During the sliding process of the sliding portion 4, the notch of the circular groove 10 remains horizontally opposite to the strip hole 8 of the plug-in portion 2.

[0042] The upper side of the latch 52 is machined with a flat surface 11, which mates with the lower surface of the sink. When the sliding portion 4 drives the elastic pin assembly 5 downward until the latch 52 extends out of the lower opening of the pre-set hole in the sink, the latch 52 is no longer restricted by the wall of the pre-set hole. The end of the latch 52 away from the spring 51 is acted upon by the restoring force of the spring 51 to extend out of the notch 10 and horizontally pass through the strip hole 8 of the plug-in portion 2, finally extending out of the plug-in portion 2.

[0043] The tensioning assembly 6 is arranged on the back side of the main body 1 and is located above the countertop of the washbasin. Finally, the operating part 9 and the sliding part 4 are simultaneously tightened upward through the tensioning assembly 6, so that the pin 52 abuts against the lower surface of the washbasin. At this time, the pin 52 can limit the sliding part 4 from sliding upward, thereby achieving the clamping of the limiting part 3 and the pin 52 on the upper and lower sides of the washbasin countertop, and finally achieving the fixation of the faucet.

[0044] Specifically, the tensioning assembly 6 includes a connecting block 61, a stud 62 vertically passing through the connecting block 61, and a handle 63 fixed to the upper end of the stud 62. The connecting block 61 is fixed to the outer wall of the back side of the body 1 and is located above the strip-shaped hole 8 of the body 1. A through hole is vertically opened on the connecting block 61 for the stud 62 to pass directly through. The inner wall of the through hole is not threaded, ensuring that the stud 62 can slide directly along the axis of the through hole and rotate circumferentially. The connecting block 61 and the operating part 9 are opposite to each other in upper and lower parts. The lower end of the stud 62 passes through the through hole and is threadedly connected to the operating part 9, and the handle 63 abuts the upper side of the connecting block 61. By rotating the handle 63, the stud 62 is driven to rotate. Since the stud 62 and the connecting block 61 are relatively stationary, the operating part 9 can be tightened upward, thereby achieving the tight abutment of the sliding part 4 and the latch 52 on the lower surface of the wash basin.

[0045] Among them, a clamping nut 12 is threaded on the stud 62, and the clamping nut 12 abuts against the lower side of the operating part 9. When the stud 62 tightens the operating part 9, the clamping nut 12 can be rotated so that the upper side of the clamping nut 12 abuts against the lower side of the operating part 9, which can reduce the loosening of the stud 62 and improve the tightening stability of the pin 52.

[0046] The implementation principle of a faucet in the embodiment of the present application is as follows: when installing, it is only necessary to insert the plug-in part 2 downward into the reserved hole of the wash basin until the limit part 3 is in contact with the wash basin countertop, and then the sliding part 4 is driven downward by the operating part 9. When the latch 52 passes through the reserved hole downward, the restoring force of the spring 51 drives the latch 52 to pass through the notch of the circular groove 10 and the strip hole 8 of the plug-in part 2 in sequence, so that the latch 52 extends out of the plug-in part 2; then the handle 63 is turned, and the operating part 9 is moved upward, driving the sliding part 4 and the latch 52 together. Move upward, and the flat part 11 on the upper side of the direct latch 52 is fitted tightly against the lower surface of the wash basin, and then the clamping nut 12 is tightened to achieve the clamping and fixation of the limit part 3 and the latch 52 on the upper and lower sides of the wash basin countertop, and finally the installation of the faucet is achieved; therefore, during the installation process, it is only necessary to operate above the countertop of the wash basin, and there is no need to squat under the wash basin. The lighting is good and there is no space restriction, especially in an environment where the space under the wash basin is more severely restricted. The overall operation is convenient, and the faucet is easy to install.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
