DETAILED DESCRIPTION

[0030] The present case will be further described in detail in combination with the drawings and specific embodiments.

[0031] The present case relates to a connection structure of a faucet water outlet pipe, which is used to connect the water outlet pipe connection end 301 of the water outlet pipe 300. As shown in the figure, the connection structure includes a first structure 1 and a second structure 2. Among them, the first structure 1 is arranged on the faucet body 100, and the second structure 2 is arranged at the waterway connection end 201 of the water inlet valve seat 200. Figures 1-2

[0032] The faucet body 100 includes the main body part 101 and the water outlet part 102 which are connected internally; the main body part 101 has a lower port for the water inlet valve seat 200 to extend into assembly; the water outlet part 102 has a water outlet for the water outlet pipe 300 to extend into assembly and realize water outlet. When the water inlet valve seat 200 is assembled in place inside the faucet body 100, the first structure 1 and the second structure 2 are in opposite assembly, thereby realizing the lock fixing of the water outlet pipe connection end 301, and the water outlet pipe connection end 301 and the waterway connection end 201 are connected in corresponding opposite positions.

[0033] ​The specific assembly steps of the new type are as follows: firstly, the water outlet pipe 300 is inserted from the water outlet part 102, the water outlet pipe connecting end 301 is extended to the position of the first structure part 1, and the water outlet pipe connecting end 301 is in a state of being separated from the first structure part 1 in a natural state without external force; then, the water inlet valve seat 200 is inserted from the lower port of the main body part 101 and is assembled by being shifted upwards along the inner cavity of the main body part 101, and when the water inlet valve seat 200 is shifted upwards to the second structure part 2 and contacts the water outlet pipe connecting end 301, the second structure part 2 abuts against the water outlet pipe connecting end 301 to be close to the first structure part 1, until the first structure part 1 and the second structure part 2 are relatively matched and tightly locked to hold the water outlet pipe connecting end 301, at this time, the water inlet valve seat 200 is assembled in place, the first structure part 1 and the second structure part 2 are relatively assembled, and at this time, the water outlet pipe connecting end 301 is just opposite to the water path connecting end 201 to be connected, thereby completing the connection and fixing of the water outlet pipe 300 in the faucet body 100 and the water inlet valve seat 200.

[0034] The first structure part 1 and the second structure part 2 are relatively matched to lock and fix the water outlet pipe connecting end 301, the locking is reflected by the relative action of the two structure parts on the water outlet pipe connecting end 301, and the specific locking mode can have various forms, and the first structure part 1 and the second structure part 2 can be in contact or not in contact in the locked state.

[0035] It should be noted that the water outlet pipe 300 is inserted from the water outlet part 102, and the control of the specific insertion depth in the operation is realized by the matching limiting structure designed between the water outlet part 102 and the water outlet pipe 300, which is the existing known technology, and specifically, the water outlet part 102 and the water outlet pipe 300 are provided with inclined limiting parts that limit each other at the corresponding water outlet position, and the axial length of the water outlet part 102 and the axial length of the water outlet pipe 300 are matched, so that the water outlet pipe 300 is inserted from the water outlet part 102 until the inclined limiting parts of the two are opposite, that is, the insertion operation of the water outlet pipe 300 is completed, at this time, the water outlet pipe connecting end 301 is just extended to the position opposite to the first structure part 1. The existing known technology is that the water inlet valve seat 200 is assembled in place in the main body part 101 of the faucet body 100, and then the relevant nut part is locked at the lower port of the main body part 101 to realize the fixing effect of the water inlet valve seat 200 after being assembled in place.

[0036] The new connecting structure is ingenious in structure design and greatly simplified. When assembling, the water inlet valve seat 200 is assembled in place in the main body part 101 at the same time, and the locking connection and fixing of the water outlet pipe 300 are completed, achieving one-step simple and fast installation. During the entire installation, only the corresponding installation of the water inlet valve seat 200 in the main body part 101 needs to be paid attention to, and this step is a necessary and simple operation in the assembly of the existing faucet. The new water outlet pipe connection and fixing are realized on the assembly operation of the water inlet valve seat, without the need to increase the installation steps, and the entire process does not need to reach the connection position or the position close to the connection position in the deep part of the faucet body to realize the alignment, and also ingeniously avoids the relatively narrow installation space of the faucet, thereby completely solving the problems of difficult installation and complicated installation of the existing faucet.

[0037] The new connecting structure adopts a different installation logic than the existing one, and the alignment assembly of the connecting structure is ingeniously set independently of the water outlet pipe without the aid of another independent accessory, optimizing the structure form, simplifying the mold production process, and achieving the unified effects of simplified production, simplified structure, simplified installation, and excellent assembly performance, meeting the market application requirements.

[0038] The first structure part 1 and the second structure part 2, specifically the locking connection structure, can have various embodiments, and various limiting connection methods known in the prior art mechanical field can be used as long as they can be assembled relative to each other to achieve locking and fixing of the water outlet pipe connection end. The preferred embodiment of the new type is given below.

[0039] In a preferred embodiment, the first structure part 1 and the second structure part 2 are respectively provided with a first open slot 11 and a second open slot 21 on the relative assembly surface, and the second structure part 2 is further provided with a waterway connection surface 22, and the corresponding waterway connection port of the water inlet valve seat 200 is located on the waterway connection surface 22. When the first structure part 11 and the second structure part 12 are assembled relative to each other, the first open slot 11 and the second open slot 12 form a locking cavity, and the waterway connection surface 22 constitutes the bottom of the locking cavity; the inner wall surface of the locking cavity, i.e. the inner groove surface of the first open slot 11 and the second open slot 12, jointly forms a circumferential (radial) constraint surface for the water outlet pipe connection end. The locking connection structure formed by the first structure part 1 and the second structure part 2 makes circumferential (radial) locking constraint to the water outlet pipe connection end, and the connection and fixing performance is stable and reliable.

[0040] Further preferably, the first structure part 1 is further provided with a step surface 12, in particular, the first open slot 11 has an inner side and an outer side in the direction in which the water outlet pipe extends, and the step surface 12 is correspondingly formed on the outer side of the first open slot 11. When the first structure part 1 is assembled with the second structure part 2, the step surface 12 forms an inner clamping surface of the clamping cavity, and the step surface 12 and the waterway connecting surface 21 form an axial constraint surface for the water outlet pipe connecting end. In this way, the clamping connection structure formed by the first structure part 1 and the second structure part 2 simultaneously clamps the water outlet pipe connecting end in the circumferential (radial) and axial directions, further enhancing the stability and reliability of the connection and fixation. The step surface 12 on the first structure part 1 is arranged in the direction in which the water outlet pipe extends,

[0041] In cooperation with the circumferential (radial) and axial clamping, the water outlet pipe connecting end 301 is provided with a clamping part, in particular, the clamping part is a flange structure arranged on the water outlet pipe connecting end 301, the flange structure has a peripheral surface 311 and a side surface 312, the first open slot 11 and the second open slot 12 surround the peripheral surface 311 to clamp it in the circumferential direction, and the step surface 12 and the waterway connecting surface 21 clamp the side surface 312 in the axial direction. The step surface 12 also has a pre-limiting function, when the water outlet pipe 300 extends into the water outlet part 102 to a position, the side surface 312 of the clamping part is just opposite to the step surface 12, and the step surface 12 has a pre-limiting function for the side surface 312 in the axial direction, which is very helpful for the first structure part 1 and the second structure part 2 to realize accurate clamping operation.

[0042] In a preferred embodiment, the first open slot 11 and the step surface 12 form a first L-shaped clamping structure arranged obliquely, and the waterway connecting surface 22 and the second open slot 21 form a second L-shaped clamping structure arranged obliquely. When the first structure part 1 is assembled with the second structure part 2, the first L-shaped clamping structure and the second L-shaped clamping structure form a clamping cavity arranged obliquely. In a specific embodiment, the waterway connecting surface 22 is arranged obliquely at an angle other than 90 degrees with the vertical direction, and in an embodiment, it is arranged obliquely upward. The second open slot 21 is arranged vertically on the waterway connecting surface 22, and they form an L-shaped half-enclosing structure (i.e., the second clamping structure) arranged obliquely upward. The first open slot 11 and the step surface 12 on the first structure part 1 are correspondingly arranged obliquely downward, forming an L-shaped half-enclosing structure (i.e., the first clamping structure) arranged obliquely downward. In this way, during the assembly of the first structure part 1 and the second structure part 2, the obliquely upward and downward half-enclosing structures guide each other, and the water outlet pipe connecting end 301 is fine-tuned and corrected during the clamping process, finally ensuring accurate and effective assembly.

[0043] In a preferred embodiment, both the first opening groove 11 and the second opening groove 21 are trapezoidal opening grooves, each including a groove bottom and guide portions connected to both sides of the groove bottom. The guide portions on both sides play a guiding and correcting role during relative assembly and also provide a certain degree of fine-tuning and correction. Specifically, the first opening groove 11 includes a first groove bottom 111 and first guide portions 112 connected to both ends of the first groove bottom 111, and the second opening groove 21 includes a second groove bottom 211 and second guide portions 212 connected to both ends of the second groove bottom 211. When the first structural part 1 and the second structural part 2 are assembled relative to each other, the first opening groove 11 and the second opening groove 21 form a polygonal locking cavity. Of course, the structure of the water outlet pipe connection end must be matched with the locking cavity. In this embodiment, the locking cavity is a polygonal locking cavity, and the water outlet pipe connection end correspondingly forms a polygonal flange structure.

[0044] The first structural part 1 and the second structural part 2 can be respectively mounted on the faucet body and the inlet valve seat. In a preferred embodiment, the first structural part 1 is integrally formed on the faucet body 100, and similarly, the second structural part 2 is integrally formed on the inlet valve seat 200. Using an integral molding method, only the original mold opening of the faucet body and the inlet valve seat is required during production, eliminating the need for additional unnecessary mold opening steps. This extremely simple mold opening process brings advantages of high efficiency and low cost.

[0045] In a preferred embodiment, an end face seal 221 is disposed on the outer periphery of the water connection end 201 of the second structural part 2. After assembly, the end face seal 221 is located between the water outlet pipe connection end 301 and the water connection end 201, ensuring the sealing performance of the connection.

[0046] This new invention also proposes a type of faucet, such as Figures 3-5 As shown, the faucet includes a faucet body 100, an inlet valve seat 200, and an outlet pipe 300. The faucet body 100 includes a main body 101 and an outlet section 102 that are connected to each other. The inlet valve seat 200 and the outlet pipe 300 are respectively assembled to the main body 101 and the outlet section 102.

The connecting structure is a faucet outlet pipe connecting structure as described above, wherein a first structural part 1 is correspondingly provided at the position in the main body 101 that is connected to the outlet section 102.

[0047] The outlet pipe 300 has a locking part at the outlet pipe connection end 301. When the inlet valve seat 200 extends into the faucet body 100 and is assembled in place, the first structural part 1 and the second structural part 2 are assembled and locked together. In a specific embodiment, the locking part is the flange structure, which has a peripheral surface 311 and a side surface 312.
