Description

Technical Field

[0001] This utility model belongs to the field of faucet technology, and specifically relates to a rust-proof directional faucet rotary joint. Background Technology

[0002] A faucet rotary joint is a component used between the water outlet pipe of a faucet and the body of the faucet. Existing faucet rotary joints typically include an inner core and a rotating sleeve fitted outside the inner core. Most rotary joints on the market have a position indicator component between the rotating sleeve and the inner core so that the user can hear the rotation sound when rotating.

[0003] For example, Chinese utility model patent publication number "CN210034717U" discloses a faucet rotary connector with a gear indicator, including an inner core, a rotating sleeve, and a gear ring. The gear ring is fixedly sleeved on the inner core, and the rotating sleeve is rotatably sleeved on the inner core, with the gear ring located on the lower side of the rotating sleeve. The upper end of the inner core is stamped with a flange to prevent the rotating sleeve from detaching from the inner core. A gear indicator component is provided between the rotating sleeve and the gear ring. The gear indicator component includes a spring fixedly connected to the rotating sleeve at its upper end, a ball fixedly installed at the lower end of the spring, and several ring-shaped holes distributed on the upper surface of the gear ring and located below the ball for embedding the ball. This utility model, by setting a gear indicator component between the inner core and the rotating sleeve, emits a clicking sound when the faucet is turned, so that the user can easily perceive that they are turning the faucet.

[0004] Although this rotary joint can produce a sound when the faucet is turned, the spring and ball bearing parts are small, making assembly cumbersome and prone to loss. Furthermore, the spring is made of metal, which is susceptible to corrosion after a period of use, polluting the water. Repairing the faucet requires replacing the entire rotary joint, which directly increases the cost of use.

[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Utility Model Content

[0006] The purpose of this utility model is to provide a rust-proof directional faucet rotary joint that is simple in structure and easy to assemble.

[0007] To achieve the above objectives, this utility model adopts the following technical solution:

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figures 1 to 5As shown, a rust-resistant directional faucet rotary joint includes a hollow inner core 1, with a mounting boss 11 at the lower part of the inner core 1. A rotating sleeve 12 is fitted onto the middle of the inner core 1, with the rotating sleeve 12 positioned on top of the mounting boss 11 when fitted onto the inner core 1. A gear position indicator component is also provided inside the rotating sleeve 12. The gear position indicator component includes several positioning posts 13 disposed within the rotating sleeve 12. The positioning posts 13 are integrally formed with the rotating sleeve 12, extending downwards from the top of the rotating sleeve 12. Each positioning post 13 is evenly arranged in a ring around the center of the rotating sleeve 12, and the positioning posts 13 are evenly arranged within the rotating sleeve 12 near its outer side wall. The gear position indicator component also includes a retaining ring 14 fixedly fitted onto the lower part of the inner core 1. Specifically, the lower inner side wall of the retaining ring 14... A plurality of anti-rotation strips 141 are uniformly fixed on the upper ring, and the anti-rotation strips 141 form a polygon. The outer side wall of the inner core 1 is provided with an anti-rotation part 101 at the position corresponding to the toothed ring 14, which matches the shape formed by the anti-rotation strips 141. Correspondingly, the shape of the anti-rotation part 101 is polygonal. The cooperation between the anti-rotation strips 141 and the anti-rotation part 101 ensures that the toothed ring 14 is fitted on the inner core 1 and will not rotate. The toothed ring 14 is located inside the rotating sleeve 12. There is a gap between the outer side wall of the toothed ring 14 and the inner side wall of the rotating sleeve 12. The top of the toothed ring 14 is provided with a plurality of teeth 142 that engage with the bottom of the positioning post 13. Specifically, a tooth groove 143 is formed between each adjacent tooth 142 for the positioning post 13 to be inserted. The bottom of the positioning post 13 is located in the tooth groove 143.

[0038] Preferably, the longitudinal section of the positioning post 13 is an inverted trapezoid, and both ends of the bottom of the positioning post 13 are provided with chamfered angles 131. This arrangement facilitates the smooth insertion of the bottom of the positioning post 13 into the tooth groove 143 on the toothed ring 14 when the rotating sleeve 12 rotates. It should be noted that the specific number of positioning posts 13 can be set according to actual usage needs. In this utility model, it is preferable to set the number of positioning posts 13 to two or more. In addition to the sound effect, two or more positioning posts 13 also have the function of controlling the weight of the hand.

[0039] Preferably, the inner wall of the middle part of the inner core 1 is provided with a sealing groove 15, and the inner wall of the rotating sleeve 12 is integrally formed with an inner sealing ring 16 corresponding to the sealing groove 15 to seal and cooperate with the sealing groove 15. This arrangement enhances the sealing performance between the rotating sleeve 12 and the retaining ring 14.

[0040] like Figure 5As shown, a positioning through hole is also provided on the outer wall of the rotating sleeve 12. A positioning component 121 connected to the water outlet pipe 20 is fixed on the positioning through hole. The rotating sleeve 12 is connected and fixed to the water outlet pipe 20 through the positioning component 121. In this utility model, the positioning component 121 is a conventional nut. The water outlet pipe 20 has a connecting through hole at the position corresponding to the positioning component 121. Screws, pins or positioning pins are simultaneously inserted into the connecting through hole and the positioning component 121 for screwing connection, thereby realizing the connection and fixation between the water outlet pipe 20 and the rotating sleeve 12.

[0041] This utility model's rust-proof directional faucet rotary joint, through the cooperation of the positioning post 13 inside the rotating sleeve 12 and the retaining ring 14 below, produces a sound when the faucet is rotated. In terms of manufacturing process, the positioning post 13 is integrally formed directly in the mold cavity during the production of the rotating sleeve 12, which is simpler, more convenient and efficient compared to existing processes, greatly saving production costs. It solves the problem in traditional gear indicator components where the spring and ball bearing parts are small, making assembly cumbersome and prone to loss. Furthermore, the positioning post 13, produced in this integral molding process, is made of a flexible material with memory properties, solving the problem in traditional technology where the spring is made of metal and is prone to corrosion after a period of use, causing water pollution.

[0042] like Figures 1 to 4 As shown, a sealing assembly 2 is also fitted onto the upper part of the inner core 1. Specifically, the sealing assembly 2 includes a sealing sleeve 21 that passes through the inner core 1 and a snap ring 22 for securing the sealing sleeve 21 to the inner core 1. The bottom of the sealing sleeve 21 abuts against the top of the rotating sleeve 12 to form a seal, preventing water from seeping between the inner core 1 and the rotating sleeve 12. An outer sealing ring 211 is integrally formed on the outer side of the sealing sleeve 21. The outer sealing ring 211 forms a seal with the water outlet pipe 20 of the faucet. Compared with the prior art, the integrally formed outer sealing ring 211 has better overall sealing performance, is less likely to be lost, and is easier to assemble. The ring 22 includes a top truncated cone 221 and multiple claws 222 extending downward from the bottom of the truncated cone 221. The sealing sleeve 21 has channels 212 for the claws 222 to extend into each claw 222. The truncated cone 221 is hollow. After the claws 222 extend into the channels 212, the inner wall of the truncated cone 221 is tightly attached to the sealing sleeve 21. The claws 222 include claw arms 223 and claw heads 224 integrally formed at the bottom of the claw arms 223. The inner wall of the sealing sleeve 21 has a space for the claw heads 224 to extend out. The upper part of the inner core 1 has an annular groove 17 for the claw heads 224 to engage.

[0043] Specifically, the upper part of the inner core 1 has two protrusions 18 arranged at intervals, forming an annular groove 17 between the two protrusions 18. The inner side wall of the bottom of the sealing sleeve 21 abuts against the outer side wall of the top of the rotating sleeve 12 below to form a seal. Correspondingly, the top of the rotating sleeve 12 has a groove that matches the sealing sleeve 21 to prevent water from seeping into the space between the inner core 1 and the sealing sleeve 21. Preferably, the bottom of the claw arm 223 is inclined inward to make the installation more secure. Multiple claws 222 are arranged in a circular array around the center of the frustum 221. The bottom of the claw head 224 is chamfered to facilitate the insertion of the claw 222 into the channel 212 at the top of the sealing sleeve 21. The sealing sleeve 21 of this utility model is made of conventional rubber material, and the buckle ring 22 is made of conventional elastic material with a certain strength, so that the buckle ring 22 has a certain tension for easy installation.

[0044] In use, the sealing sleeve 21 is first placed on the upper part of the inner core 1. Then, the claws 222 of the snap ring 22 are inserted into the sealing sleeve 21 through the channel 212 at the top of the sealing sleeve 21, and the snap ring 22 is snapped onto the annular groove 17 of the inner core 1 through the claw head 224, thus forming the sealing component 2. With this structure, the assembly is firm and the two are not easy to separate. By setting the sealing component 2, the outer sealing ring 211 is integrally formed on the sealing sleeve 21, resulting in a good sealing effect. The snap ring 22 and the sealing sleeve are engaged to fix the sealing sleeve 21 onto the inner core 1. The snap ring 22 and the sealing sleeve 21 are engaged. With this structure, the snap ring 22 can be assembled flexibly and installed firmly. The sealing component 2 and the inner core 1 are not easy to separate. The overall sealing performance and stability are good, and it is easy to assemble.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
