Description

Technical Field

[0001] This invention relates to a quick-assembly and disassembly structure for a faucet. Background Technology

[0002] The existing technology of a separate faucet has the problem that the faucet body assembly has a complex component structure and a large size.

[0003] Meanwhile, existing technology also discloses a water circuit fixing structure for a faucet body assembly. This structure first uses a stop plate to fix the inlet and outlet pipes to the plastic body, and then uses a flange to fix a metal sleeve to the plastic body, thus achieving a fixing structure between the faucet body assembly and the water supply pipe in a separate faucet. However, this fixing structure still suffers from structural complexity, and the assembly of the various components is cumbersome, with numerous assembly steps and low controllability.

[0004] Existing technology also includes a split-type faucet body water circuit fixing structure, including a body base and inlet and outlet pipes fixed to the body base by a stop plate. Its structural features are: the body base includes a sleeve and a body disposed within the sleeve, the body and sleeve being an integral secondary injection molding structure; the body has two connecting holes for connecting the inlet and outlet pipes; the inner periphery of the sleeve corresponding to the connecting holes of the body has two opposing limiting steps; and the stop plate has two notches for fixing the inlet and outlet pipes respectively. The opening of the notch corresponds to the limiting steps, allowing the stop plate to fall into the inner end of the limiting steps, and the edge of the stop plate, after rotation, engages with the inner end of the limiting steps. This fixing structure uses a secondary injection molding process and a manual screw-on stop plate assembly method, still suffering from complex processes, numerous production steps, and low controllability. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a quick assembly and disassembly structure for a faucet.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] The term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the invention. In the description of the invention, it should be understood that the terms "upper," "lower," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0027] Referring to the accompanying drawings, a quick-assembly and disassembly structure for a faucet includes a body 10. A connector 12 is located at the bottom of the body, into which a pipe 20 is inserted. An opening 11, which connects to the connector, is located on the outer periphery of the body. An elastic arm 40 is located on the opening. A locking protrusion 21 is located on the outer periphery of the end of the pipe inserted into the connector. The elastic arm engages with the locking protrusion to securely connect the pipe to the body. In this invention, the body can be made of plastic and is integral with the elastic arm. When the pipe is inserted into the connector, the elastic arm, under its elastic force, guides the pipe into the connector. After insertion, the elastic arm springs back to its original position and presses against the locking protrusion, thus securing the pipe to the body.

[0028] The present invention also includes a threaded tube 30 that can be fitted around the outer periphery of the main body. Normally, the threaded tube is made of metal, such as copper. The threaded tube fits around the outer periphery of the main body, and the outer periphery of the main body adapts to the inner periphery of the threaded tube. Preferably, the outer periphery of the main body is also cylindrical. The outermost end 41 of the elastic arm can extend to the outer periphery of the main body. Preferably, the radius of the main body is smaller than the distance from the central axis of the main body to the outermost end of the elastic arm. In this way, when the main body and the pipe are inserted and the threaded tube is inserted, the inner periphery of the main body squeezes the elastic arm, causing the elastic arm to move towards the central axis of the main body. This increases the contact area between the elastic arm and the locking boss, making the pipe more firmly fixed to the main body.

[0029] Furthermore, to facilitate the insertion of the threaded pipe after the fitting is inserted into the main body, the elastic arm extends out of the outer periphery of the main body and is provided with a guide slope 42 that can mate with the threaded pipe. Referring to the attached drawings, the lowest end of the guide slope is adapted to the outer periphery of the main body, and the highest end of the slope, that is, one end of the outer periphery of the elastic arm, can extend out of the outer periphery of the main body in the normal relaxed state. The innermost end 43 of the elastic arm can be supported below the lower end face of the snap-fit ​​boss. That is to say, in the relaxed state, the innermost end of the elastic arm and the snap-fit ​​boss have a vertically overlapping surface. In this way, when the fitting is inserted into the insertion interface, the first part of fixation is formed. Then, after the threaded pipe is fitted in, the overlapping surface between the elastic arm and the snap-fit ​​boss increases, which can make the fitting more securely fixed to the main body. Similarly, the elastic arm can retract inward under the action of the threaded pipe, and it can also extend outward under the action of external force. This allows the pipe fitting to be removed from the body when the elastic arm extends outward. Ideally, when the elastic arm is in a relaxed state, the overlap surface between the innermost end of its elastic arm and the locking protrusion is very small. As long as the pipe fitting does not fall out of the insertion interface under its own weight, it is acceptable.

[0030] Furthermore, the uppermost end of the elastic arm is provided with a snap-fit ​​surface 44 that mates with the lower end face of the snap-fit ​​boss. This snap-fit ​​surface mates with the lower end face of the snap-fit ​​boss, and the pipe is fixed to the body through the vertical overlapping surface. The outermost end of the snap-fit ​​surface extends out of the body and can mate with the threaded pipe. The innermost end of the snap-fit ​​surface is located inside the snap-fit ​​boss, which is the relaxed state of the elastic arm. The wall thickness L1 of the snap-fit ​​surface is greater than the wall thickness L2 of the body at the insertion interface. Please refer to the attached drawings in the specification for details.

[0031] In one embodiment of the present invention, the outer peripheral wall of the main body is provided with at least two openings and an elastic arm, and the main body is provided with at least two insertion interfaces, namely at least one water inlet insertion interface 13 and one water outlet insertion interface 14; the pipe includes a water inlet pipe 22 and a water outlet pipe 23, the water inlet pipe is connected to the water inlet insertion interface, and the water outlet pipe is connected to the water outlet insertion interface.

[0032] Refer to the attached diagram in the instruction manual. Figure 3 The figure shows a main body with two openings, each with a flexible arm, and two insertion ports and two pipe fittings as an example. In order to make the structure foolproof, the different openings are set at different heights on the outer periphery of the main body. The dotted line in the figure is the height reference line of one of the openings. That is to say, after the two pipe fittings are inserted into the insertion ports, the two locking protrusions are at different heights, forming a height difference, which can prevent installation errors.

[0033] In use, a boss 31 is provided on the inner circumference of the lower end of the threaded tube, and the lower end face of the body can support the boss. A protrusion 15 is provided on the outer circumference of the upper end of the body, and the protrusion contacts and engages with the upper end face of the threaded tube. A locking nut 50 is provided between the body and the threaded tube, and a limiting protrusion 51 that mates with the protrusion is provided on the upper inner circumference of the locking nut, which ensures the accurate positional relationship between the components. Furthermore, a snap-fit ​​block 16 is provided below the protrusion, and a notch 32 is provided on the upper end of the threaded tube to allow the snap-fit ​​block to engage, which ensures accurate installation of the body and the threaded tube and prevents rotation.

[0034] More specifically, this invention relates to a quick-installation, split-type faucet body structure, comprising a locking nut, a body, a threaded tube, an inlet pipe, and an outlet pipe. Elastic arms, also known as clips, are located on both sides of the bottom of the body. The maximum outer diameter of the clips protrudes beyond the outer diameter of the body. After the inlet and outlet pipes are inserted into the inlet and outlet connectors from the bottom of the body, they are held in place by the elastic arms. The threaded tube is then fitted onto the outside of the body from the inlet and outlet pipe ends. The elastic arms on both sides of the body are pressed together by the inner wall of the threaded tube and move towards the center of the body, further securing the inlet and outlet pipes and ensuring they can withstand sufficient strength and are not easily dislodged. A boss is located at the bottom of the inner circumference of the threaded tube, abutting against the bottom plane of the body, further enhancing the security of the inlet and outlet pipes fixed inside the body and enabling them to withstand greater strength. After the locking nut is inserted from the top of the body, it engages with the threads of the threaded tube, fixing the body between the locking nut and the threaded tube, forming the faucet body structure. The elastic arms on both sides of the body have a staggered design, acting as a foolproof mechanism to effectively prevent incorrect installation of the inlet and outlet pipes.

[0035] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
