Description

Technical Field

[0001] This utility model relates to the field of pull-out faucet accessories, specifically to a gravity ball assembly for pull-out faucets. Background Technology

[0002] Pull-out faucets are widely used in daily life. When users need to use water at a certain distance from the faucet (such as for washing hair or vegetables), they simply pull out the flexible hose inside the faucet. In actual use, to facilitate the quick return of the pulled-out hose, a gravity ball (or weight) is often installed on the hose, using its own weight to make the hose return quickly. However, the use of such a gravity ball (or weight) on the hose has the following drawbacks:

[0003] First, because the weight of the gravity ball itself will cause the hose to return to its original position, one hand must be held to hold the hose after each pull-out to prevent it from returning to its original position, which causes inconvenience to users, such as the inability to wash hair or vegetables with both hands after the hose is pulled out.

[0004] Secondly, repeated pulling of the hose can easily damage it and affect its service life. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] Reference Figures 1 to 8 As shown, a gravity ball assembly for a pull-out faucet includes a first component 1 mounted on a hose 10 and a second component 2 mounted on the bottom of the faucet 20. The first component 1 has a first longitudinal opening 11 penetrating its inner side, and the second component 2 has a second longitudinal opening 21 penetrating its inner side. A locking structure is provided between the first component 1 and the second component 2. In use, after pulling out the hose, the first component 1 is fixed to the second component 2, preventing the hose from automatically returning to its original position after being pulled out. This allows for positional fixation after the hose is pulled out, eliminating the need for the user to hold the hose with one hand while operating the rinsing motion with the other, thus meeting the user's operational needs, reducing the number of hose pulls, and extending the hose's lifespan.

[0039] Specifically, in order to fix the first component onto the second component, the engaging structure of this utility model adopts the following specific structure: the engaging structure includes a locking block 3 formed on the first component 1 and multiple guide seats 4 formed on the second component 2. Each pair of adjacent guide seats 4 is spaced apart to form a locking groove 5 between the two guide seats 4 and adapted to the locking block 3. Each guide seat 4 is provided with a guide surface 6 to guide the locking block 3 into the locking groove 5. When the locking block of the first component 1 is to be engaged into the locking groove 5, the locking block 3 will first be guided into the locking groove 5 by the guide surface, ensuring that the first component and the second component can be engaged in any position and will not fail to be fixed due to the locking block not being aligned with the locking groove 5.

[0040] The first component 1 includes a counterweight 12, a connector 13 that engages with the second component 2, and a locking nut 7 for fixing the hose 10 to the counterweight 12. One end of the counterweight 12 is connected to the locking nut 7, and the other end is connected to one end of the connector 13. The other end of the connector 13 can be inserted into the second component 2, and a locking block 3 is provided on the outer side of this end. The counterweight 12 has a coaxial through hole 8 at its center along the axial direction. During installation, the hose passes through the locking nut 7 and the through hole 8 of the counterweight 12 in sequence, then through the second longitudinal opening 21 of the second component 2, and finally enters the faucet body to connect with the spout.

[0041] Additionally, the second component 2 includes a tubular upper cover 22 and a lower cover 23, which are detachably connected. More specifically, the upper cover 22 has an internal thread on its inner side, and the lower cover 23 has an external thread 230 on its outer side. The upper cover 22 and the lower cover 23 are connected by the engagement of the internal and external threads 230, allowing them to be detached. Of course, the upper cover 22 and the lower cover 23 can also be connected using other detachment methods, such as snap-fit ​​connections.

[0042] It should be noted that the upper cover 22 is provided with a threaded connector 221 that connects to the threaded tube 24 at the bottom of the faucet, and the lower cover 23 is provided with a second nut connector 231, which is convenient to use a wrench tool to match the second nut connector 231, so that the second component can be tightened onto the threaded tube 24.

[0043] Furthermore, the connector can be engaged to fix the first component 1 onto the second component 2. Inside the lower cover 23, a locking sleeve 9 is provided for the insertion and engagement of the connector 13. Multiple guide seats 4 are circumferentially arranged on the inner side of the locking sleeve 9. Each guide seat 4 protrudes inwards from the locking sleeve 9 and is spaced apart circumferentially along the lower cover 23. A groove 5 is formed between every two adjacent guide seats 4. Above each groove 5, a limiting block 90 is provided on the inner wall of the locking sleeve 9. The limiting block 90 prevents the connector 13 from passing through the locking sleeve 9, thus preventing the hose from easily returning to its original position. A guide surface 6 is located at the lower end of the guide seat 4 and is inclined. When the connector 13 is inserted into the locking sleeve 9, the locking block 3 on the outside of the connector 13 will first pass through the guide surface 6 and enter the groove 5, ensuring that the first component 1 and the second component 2 can engage in any position, and preventing the connector 13 from failing to be fixed in the locking sleeve 9 due to the locking block 3 not aligning with the groove 5.

[0044] It should also be noted that the lock nut 7 has through holes 8 extending through both its upper and lower ends. The outer surface of the lock nut 7 has external threads for connection with the counterweight 12. One end of the lock nut 7 has a first nut connector 70, which, when fitted with a wrench, allows for a secure connection between the lock nut 7 and the counterweight 12. The other end of the lock nut 7 has multiple clamping parts 71 for clamping the flexible hose 10, spaced apart along the circumference of the lock nut 7. Each clamping part 71 has an abutment part 72 at its upper end that abuts against the flexible hose 10, bent towards the side of the hose 10. When the hose passes through the through hole 8, the clamping part 71, made of a tough material, provides elasticity, thus securing the hose. The abutment part 72 tightly grips the hose, ensuring a more secure connection between the lock nut 7 and the hose.

[0045] In order to fix the clamping sleeve 9 inside the upper cover 22, a boss 220 for positioning the clamping sleeve 9 is provided on the inner side of the upper cover 22 so that the clamping sleeve 9 can be fixed inside the upper cover 22. The boss 220 is protruding along the circumference of the clamping sleeve 9. The boss 220 can be in the shape of a ring or an arc, as long as it can position the clamping sleeve 9.

[0046] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
