Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a quick-connect faucet. Background Technology

[0002] Faucets are one of the most common water supply devices in daily life. A faucet installation structure is a set of connection and fixing devices used to securely install faucets in their place of use, such as washbasins, kitchen countertops, walls, or pipe interfaces.

[0003] The existing faucet installation structure is relatively complex, requiring additional auxiliary components such as PE pipes to achieve a stable connection. This not only increases the number of parts, but also makes the assembly process cumbersome, requiring pipe connection operations, making installation and maintenance inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a quick-connect faucet that eliminates the need for additional PE pipes or connecting transition parts required in traditional structures, while ensuring connection stability through a compact connector assembly.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-connect faucet, comprising a faucet body, a fixing screw disposed at the bottom of the faucet body, and a connector assembly installed on the fixing screw. The connector assembly includes a cover and a quick-connect connector partially extending into and connected to the cover. The quick-connect connector is provided with a plurality of claws for clamping water pipes. The fixing screw is provided with a pressing part, which presses the claws, driving the claws to converge toward the center.

[0006] By adopting the above technical solution, the connector assembly eliminates the need for a PE pipe, resulting in a more compact structure. When an external water pipe is inserted, the squeezing part can drive the claws to tighten, achieving a stable clamping of the water pipe. This allows the installation process to be completed quickly without the use of tools, improving assembly efficiency and reducing the risk of leakage.

[0007] The present invention is further configured such that: a beveled surface is provided on the outer periphery of the claw, and the beveled surface extends to the end of the claw; a beveled surface is provided on the outer periphery of the claw, and the beveled surface extends to the end of the claw; a guide bevel is provided on the inner wall of the extrusion part, and the guide bevel slides in cooperation with the beveled surface to drive the claw to converge toward the center.

[0008] By adopting the above technical solution, the guide slope and the inclined surface slide together, guiding the claws to gradually converge towards the center, thereby achieving a stable clamping of the water pipe.

[0009] The present invention is further configured such that: a connecting hole is provided in the body of the cover, an annular groove is provided on the wall of the connecting hole, a guide inclined surface is provided above the annular groove, an insertion hole is formed below the annular groove, and the quick connector is inserted into the insertion hole.

[0010] By adopting the above technical solution, the quick-connect connector can be accurately inserted and stably held inside the cover, preventing it from loosening or falling off.

[0011] The present invention is further configured such that the inner diameter of the guide ring formed by the guide slope is greater than the diameter of the insertion hole and smaller than the inner diameter of the slope.

[0012] By adopting the above technical solution, the inner diameter of the insertion hole is smaller than the outer diameter of the lower end of the chuck, ensuring that the chuck can be brought together upwards while being unable to come out downwards, thus improving structural stability.

[0013] The present invention is further configured such that the inner wall of the claw is provided with damping ribs.

[0014] By adopting the above technical solution, the damping rib can provide a certain friction force when the clamping claws clamp the water pipe, thereby enhancing the stability of the clamping.

[0015] The present invention is further configured such that: the fixing screw is provided with a water inlet channel communicating with the faucet body, and the inner cavity of the squeezing part and the water inlet channel form an installation slot for connecting with an external water pipe, and the upper end of the installation slot is provided with a stop part.

[0016] By adopting the above technical solution, the mounting slot can be connected to an external water pipe, and the stop part can prevent the water pipe from being over-inserted, ensuring the water flow channel is connected while enhancing the stability of the connection.

[0017] The present invention is further configured such that: a first limiting rib is provided on the inner wall of the cover, and a second limiting rib is provided on the outer wall of the extrusion part, wherein the first limiting rib and the second limiting rib cooperate in a limiting manner.

[0018] By adopting the above technical solution, the cooperation between the first limiting rib and the second limiting rib can prevent the cover from falling off and ensure the stability between the cover and the extrusion part.

[0019] The present invention is further configured such that: the inner wall of the cover is provided with an internal thread and is located above the first limiting rib; the outer wall of the extrusion part is provided with an external thread and is located above the second limiting rib; and the external thread and the internal thread are threadedly engaged.

[0020] By adopting the above technical solution, the cover can be reliably installed on the extrusion part by screwing it on, and the up and down position of the cover can be adjusted by rotating it to drive the quick-connect connector to move up and down.

[0021] The present invention is further configured such that: the lower end of the first limiting rib is provided with a first mounting slope, and the upper part of the second limiting rib is provided with a second mounting slope that cooperates with it.

[0022] By adopting the above technical solution, the cover is inserted into the extrusion part from bottom to top. During the insertion process, the first mounting slope and the second mounting slope slide together, making the assembly smoother and improving the ease of installation.

[0023] The present invention is further configured such that the extrusion section is provided with multiple sealing rings.

[0024] By adopting the above technical solution, the outer end of the sealing ring abuts against the inner wall of the extrusion part, and the inner end abuts against the surface of the external water pipe, which can form a multi-layer seal at the water pipe connection, further improving the waterproof performance and effectively preventing leakage.

[0025] In summary, this utility model has the following beneficial effects: 1. This utility model eliminates the need for additional PE pipes or connecting transition parts required in traditional structures, and the joint assembly has a compact structure while ensuring the stability of the connection.

[0026] 2. This utility model only requires inserting the water pipe into the mounting slot of the extrusion part, and rotating the cover will complete the clamping connection through the interaction of the guide slope and the claw slope, which significantly improves the assembly efficiency.

[0027] 3. This utility model uses the sliding fit between the first and second mounting inclined surfaces to make assembly smoother and improve installation convenience. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] like Figures 1 to 3 As shown, the quick-connect faucet provided by this utility model includes a faucet body 1, a fixing screw 2, a connector assembly 3, and an external water pipe that cooperates with it. The bottom of the faucet body 1 extends integrally to form the fixing screw 2. The fixing screw 2 has a water inlet channel 22 that communicates with the inside of the faucet body 1 to facilitate the flow of tap water. The bottom end of the fixing screw 2 has a pressing part 21. The inner cavity of the pressing part 21 forms an installation slot 23. The upper end of the installation slot 23 forms a stop part 24. When the external water pipe is inserted into the installation slot 23, its end is limited by the stop part 24, thereby preventing the water pipe from being over-inserted and ensuring that the water flow channel remains unobstructed in the plugged state.

[0035] like Figure 3 and Figure 4 As shown, the connector assembly 3 is installed at the lower end of the fixing screw 2. The connector assembly 3 includes a cover 31 and a quick-connect connector 32 installed inside the cover 31. The cover 31 has a cylindrical structure and a connecting hole 313 inside. An annular groove 314 is provided on the wall of the connecting hole 313. A guide slope 317 is provided above the annular groove 314, and an insertion hole 3131 is formed below the annular groove 314. The quick-connect connector 32 is inserted into the insertion hole 3131. The outer wall of the extrusion part 21 is provided with an external thread 212 corresponding to the internal thread 312 and a corresponding first limiting rib 3. The second limiting rib 211 of 11 is used to fit the cover 31 from bottom to top into the extrusion part 21 during assembly. During the insertion process, the first mounting inclined surface 3111 and the second mounting inclined surface 2111 slide into each other, allowing the cover 31 to slide in smoothly and be positioned on the outer wall of the extrusion part 21. As the cover 31 continues to rotate, the internal thread 312 and the external thread 212 engage, thereby adjusting the upper and lower position of the cover 31. The lower end face of the first limiting rib 311 and the upper end face of the second limiting rib 211 abut against each other to prevent the cover 31 from falling off during use.

[0036] like Figure 2 and Figure 3 As shown, the quick-connect connector 32 is assembled inside the cover 31. A limiting groove 323 is provided on its outer wall for engaging with the annular groove 314. The lower end of the quick-connect connector 32 is provided with multiple claws 321 distributed circumferentially. Each claw 321 has a damping rib 324 formed on its inner wall to provide additional friction when clamping the water pipe. The inner wall of the claw 321 is provided with an arc-shaped clamping surface that matches the outer diameter of the external water pipe. One end of the claw 321 is provided with a beveled part 322. The fixing screw 2 is provided with a pressing part, which presses the claw 321, driving the claw 321 to converge towards the center.

[0037] like Figure 2 and Figure 3 As shown, the extrusion part includes a guide slope 317 on the inner wall of the extrusion part 21. The guide slope 317 and the sloped part 322 on the claw 321 are opposite to each other and maintain a sliding fit. When the user rotates the cover 31 to move the quick connector 32 upward, the claw 321 is squeezed by the guide slope 317 and retracts radially inward, so that the claw 321 is tightly pressed against the outer surface of the water pipe. At the same time, the damping rib 324 on the inner wall of the claw 321 abuts against the water pipe to achieve clamping. With this structural design, the user only needs to insert the water pipe and rotate the cover 31 during installation. Without the need for a wrench or other tools, quick assembly can be completed. The inner diameter of the guide ring formed by the guide slope 317 is larger than the diameter of the insertion hole 3131 and smaller than the inner diameter of the sloped part 322, so that the claw 321 can be gathered upward and prevent the claw 321 from falling out downward.

[0038] Multiple sealing rings 4 are provided on the inner wall of the extrusion part 21 of the fixed screw 2. The outer end of each sealing ring 4 is tightly fitted with the inner wall of the extrusion part 21, and the inner end abuts against the outer surface of the water pipe, thereby forming a multi-layer seal between the water pipe and the extrusion part 21, effectively preventing water from leaking from the joint.

[0039] like Figure 2 and Figure 3 As shown, the bottom of the cover 31 is provided with an installation arc 316, which is located below the quick connector 32. When the quick connector 32 is assembled from bottom to top, the installation arc 316 can cooperate with the inclined surface 322 on the claw 321 to form a guiding effect, so that the claw 321 gradually closes during the assembly process and is released after passing through the insertion hole 3131, thereby improving the smoothness of assembly and positioning accuracy. The cover 31 is also provided with multiple through drainage grooves 315. When the quick connector 32 or the sealing part has a small amount of water seepage due to long-term use, the seepage water can be quickly discharged along the drainage grooves 315 to prevent water from remaining inside the connector assembly 3 and causing corrosion or aging.

[0040] The basic working principle of this utility model is as follows: When a user needs to install this quick-connect faucet, the connector assembly 3 is first pre-assembled onto the fixing screw 2 at the bottom of the faucet body 1. The cover 31 is threaded onto the connector, and the quick-connect connector 32 is located inside the cover 31. The claws 321 are in a naturally open, ready-to-insert state. When installing an external water pipe, the user only needs to push the end of the water pipe into the mounting slot 23 at the bottom of the faucet. As the water pipe is gradually inserted, its outer wall will sequentially contact the multiple claws 321 inside the quick-connect connector 32, and finally the end of the water pipe will reach the top of the mounting slot 23. The stop part 24 prevents excessive insertion from obstructing the flow channel. Subsequently, the user rotates the cover 31. Since one end of the claw 321 is provided with a beveled part 322, and the inner wall of the squeezing part 21 is provided with a corresponding guide bevel 317, when the user rotates the cover 31, the cover 31 drives the claw 321 upward. Under the guidance of the guide bevel 317, the beveled part 322 of the claw 321 is forced to retract towards the center. This retraction action causes the inner wall of the claw 321 to gradually press against the outer wall of the water pipe. The damping rib 324 on the claw 321 further enhances the friction, making the water pipe firmly locked.

[0041] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
