Description

Technical Field

[0001] The present invention relates to a counterweight for a pull-out faucet and a pull-out faucet. Background Art

[0002] The pull-out faucets on the market include a faucet body, a water outlet head, a pull-out tube, a valve core, and a weight. The water outlet head abuts against the faucet body. The pull-out tube is connected to the valve core and passes through the faucet body to connect to the water outlet head. The pull-out tube is located under the table and the weight is clamped on the pull-out tube. Its disadvantages are as follows: 1. It is necessary to adjust its hanging position under the table; 2. The installation of the weight is relatively cumbersome; 3. The length of the faucet pulled out is relatively short, and the length of the hose is wasted greatly. For example, Chinese Invention CN208778795U discloses a weight assembly for a pull-out faucet, including a weight body. A clamping groove is formed by concave inward on one side of the weight body. A rotating pressing sleeve is also sleeved outside the weight body at the clamping groove. The rotating pressing sleeve is provided with a notch. When installing the weight assembly, rotate the rotating pressing sleeve to make its notch correspond to the clamping groove, then put the faucet pull-out tube into the clamping groove from the notch of the rotating pressing sleeve, and then rotate the rotating pressing sleeve to make its notch misaligned with the clamping groove. At this time, the rotating pressing sleeve squeezes the faucet pull-out tube against the inner wall of the clamping groove, so that the weight assembly can be locked and fixed on the faucet pull-out tube by its own gravity, and the position between the weight body and the pull-out tube is fixed. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art and provide a counterweight for a pull-out faucet and a pull-out faucet.

[0004] To solve the above technical problems, the present invention provides a counterweight for a pull-out faucet, including a counterweight body and a connecting member. The starting end of the connecting member is connected to the counterweight body, and the ending end of the connecting member extends outward to form a sliding inner wall, and the sliding inner wall is a curved surface with a smooth transition; the ending end of the connecting member is spaced from the counterweight body by a spacing dimension to form an embedding notch, and the spacing dimension is smaller than the diameter dimension of the pull-out tube of the pull-out faucet; when the pull-out tube is embedded into the sliding inner wall from the embedding notch, the connecting member can elastically deform so that the pull-out tube can pass through the embedding notch, and the sliding inner wall can slide on the pull-out tube.

[0005] In a better embodiment, both sides of the sliding inner wall include side openings, the side openings face upward when the counterweight is in use, and the pull-out tube is configured to pass through the sliding inner wall and the two side openings of the sliding inner wall.

[0006] In a better embodiment, the sliding inner wall is a curved cylindrical surface, and the diameter dimension of the cylindrical surface is greater than or equal to the diameter dimension of the pull-out tube.

[0023] The following further describes the present invention in conjunction with the accompanying drawings and specific implementation manners.

[0024] Refer to Figures 1-5 , a counterweight 1 for a pull-out faucet, the counterweight 1 is adapted to be connected to a draw tube 2 of a pull-out faucet, and the draw tube 2 is a pipe connected between the valve core and the water outlet head 5 of the pull-out faucet. As Figure 1 and Figure 5 shown, the draw tube 2 is respectively connected to the valve core and the water outlet head 5 to form a "U" shape, and the counterweight 1 is connected to the bottom end of the draw tube 2. When the water outlet head 5 is pulled by the user, the counterweight 1 is driven to rise. When the user does not pull the water outlet head 5, the draw tube 2 is driven by the counterweight 1 to drive the water outlet head 5 back to the initial position, for example, on the water nozzle of the faucet body 3.

[0025] The counterweight 1 includes a counterweight main body 11 and a connecting member 12. The starting end 121 of the connecting member 12 is connected to the counterweight main body 11. The end 122 of the connecting member 12 extends outward to form a sliding inner wall 123, and the sliding inner wall 123 is in the shape of a smoothly transitioning curved surface; the end 122 of the connecting member 12 is spaced from the counterweight main body 11 by a spacing dimension to form an embedding notch 124, and the spacing dimension is smaller than the diameter dimension of the draw tube 2 of the pull-out faucet; when the draw tube 2 is embedded into the sliding inner wall 123 from the embedding notch 124, the connecting member 12 can elastically deform so that the draw tube 2 can pass through the embedding notch 124, and the sliding inner wall 123 can slide on the draw tube 2. It should be noted that the connecting member 12 can be integrally connected to the counterweight main body 11 (such as integrally formed), or the connecting member 12 can also be separately connected to the counterweight main body 11.

[0026] The embedded notch 124 extends along the axial direction of the draw tube 2. The draw tube 2 can be pressed against the embedded notch to be pressed into the sliding inner wall 123. After embedding, the connecting member 12 can return to its original state to prevent the draw tube 2 from running out again. The sliding inner wall 123 is in the shape of a smoothly transitioning curved surface, which enables the sliding inner wall 123 to slide smoothly on the draw tube 2. Therefore, when the water outlet head 5 is pulled up and the draw tube 2 moves upward, the counterweight 1 is under the action of gravity and remains approximately at the bottom end of the draw tube 2, and the length of the draw tube 2 can be made shorter.

[0027] Both sides of the sliding inner wall 123 include side openings 125 facing upward (when the counterweight 1 is in use). The draw tube 2 is configured to pass through the sliding inner wall 123 and the two side openings 125 of the sliding inner wall 123. Since the draw tube 2 extends upward on both sides of the connecting member 12, the upward side openings 125 can make the sliding smoother. It should be noted that the upward here can be interpreted as inclined upward away from each other, and this is not limited thereto. In this embodiment, the sliding inner wall 123 is a curved cylindrical surface, and the diameter dimension of the cylindrical surface is greater than or equal to the diameter dimension of the draw tube 2. Therefore, there will be no jamming phenomenon between the cylindrical surface and the draw tube 2. The connecting member 12 includes a first plate body 126 connecting the counterweight main body 11 and a second plate body 127 forming the sliding inner wall 123; the first plate body 126 extends in a direction away from the counterweight main body 11, and the second plate body 127 connects the first plate body 126 and bends and extends toward the counterweight main body 11. The first plate body 126 and the second plate body 127 can be integrally formed, or can be connected by split splicing or any other connection method.

[0028] The counterweight main body 11 includes a receiving chamber 111 and one or more counterweight blocks 112 that can be arranged on the receiving chamber 111, and the counterweight blocks 112 can be replaced according to requirements. In this embodiment, the receiving chamber 111 includes a bottom wall 1111 and a peripheral wall 1112, and the peripheral wall 1112 is connected around the bottom wall 1111; the starting end 121 of the connecting member 12 is connected to the peripheral wall 1112. Therefore, the connecting member 12 does not affect the capacity of the receiving chamber 111.

[0029] The counterweight main body 11 further includes a cover body 113, and the cover body 113 is detachably covered on the peripheral wall 1112 to close the receiving chamber 111. The cover body 113 can be connected to the peripheral wall 1112 in a common manner. For example, one side of the cover body 113 can be pivotally connected to the peripheral wall 1112, and the other side rotates to be snap-connected to the peripheral wall 1112; or, the cover body 113 can be connected by a rotational snap-fit method.

[0030] In this embodiment, the opening of the accommodating chamber 111 and the embedding notch 124 are located on the same side of the counterweight member 1. During use, the counterweight member 1 can be connected to the draw tube 2 from back to front. As long as the opening of the accommodating chamber 111 also faces forward, rapid debugging can be achieved, which is not only convenient for installation but also convenient for adjusting the weight of the counterweight member 1.

[0031] The inner sidewall of the peripheral wall 1112 further includes one or more fastening ribs 1113 for clamping against the counterweight block 112. The fastening ribs 1113 can prevent the counterweight block 112 from shaking in the accommodating chamber 111 and generating noise, providing a good user experience.

[0032] The pull-out faucet includes a faucet body 3, a valve core, a water outlet head 5, a hot water inlet pipe 6, a cold water inlet pipe 7, and a draw tube 2. The faucet body 3 is arranged on the countertop of the kitchen sink. The valve core is located within the faucet body 3. The cold water inlet pipe 7 and the hot water inlet pipe 6 are respectively connected to a cold water source and a hot water source, and the cold water inlet pipe 7 and the hot water inlet pipe 6 are also connected to the valve core. The valve core is a common mixing valve core. One end of the draw tube 2 is connected to the valve core, and the other end extends through the faucet body 3 and is connected to the water outlet head 5. The water outlet head 5 abuts against the faucet body 3. The counterweight member 1 is embedded in the draw tube 2 through the embedding notch 124. During use, due to the action of gravity, the counterweight member 1 generally remains at the bottom end of the draw tube 2. When it is necessary to change the weight of the counterweight member 1, it can also be achieved by changing the number or weight of the counterweight blocks 112 in the accommodating chamber 111.

[0033] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantive modifications to the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
