Referring to fig. 1 to 4, a preferred embodiment of a kitchen faucet includes a support spring 10, a bushing 20, and a faucet body 30.

As shown in fig. 2, the faucet body 30 adopts a three-way structure, and an insertion portion 31 is provided at the top end thereof, and the insertion portion 31 is cylindrical; the insertion portion 31 is provided with a concave-convex engagement portion on the outer periphery. The male and female engagement portion includes a second groove 32 extending along the circumferential direction of the insertion portion 31 and having a ring shape. The number of the second grooves 32 can also be two or three, but not limited to this; moreover, the second groove 32 can be designed to be broken.

The bush 20 is provided with a first concave-convex portion at an outer periphery thereof and a second concave-convex portion at an inner wall thereof, the bush 20 extends into the support spring 10, the first concave-convex portion is fitted to the inner wall of the support spring 10, the insertion portion 31 extends into the bush 20, and the second concave-convex portion is fitted to the concave-convex fitting portion.

In this embodiment, the first concave-convex portion includes a plurality of spiral first protrusions 21, and the first protrusions 21 are matched with the recesses between two adjacent coils of springs on the inner wall of the support spring 10, that is, the two are completely matched, so that the pulling-out preventing effect is better. As shown in fig. 2, the first protrusions 21 are provided in two sets and are spaced up and down, and each set of the first protrusions 21 includes two first protrusions 21 spaced side by side.

In the present embodiment, the second concavo-convex part includes four second protrusions 22 extending in the circumferential direction of the bush 20. As shown in fig. 4, the bushing 20 is further provided with four through grooves 23 extending along the height direction thereof, the through grooves 23 extend to the top end surface of the bushing 20, a deformation portion 24 is defined between two adjacent through grooves 23, and the second protrusions 22 are disposed on the inner wall of the corresponding deformation portion 24, that is, the second protrusions 22 and the deformation portion 24 are in a one-to-one correspondence relationship.

And, the bottom end of the bush 20 is provided with an annular flange 25, and the flange 25 is clamped between the bottom end of the support spring 10 and the tap body 30.

In this embodiment, the insertion portion 31, the bushing 20 and the bottom end portion of the support spring 10 are coaxially arranged.

The kitchen faucet assembly process is as follows:

firstly, the top end of the bush 20 extends into the support spring 10 from the bottom end opening of the support spring 10 until the flange 25 abuts against the bottom end face of the support spring 10, and at the moment, the two groups of first bulges 21 are both in embedded fit with the depressions on the inner wall of the support spring 10;

then, the inserting portion 31 is extended into the lining 20 from the bottom end of the lining 20 until the faucet body 30 abuts against the flange 25, and in the inserting process, the deformation portion 24 is pressed by the inserting portion 31 to deform outwards to give way to the inserting portion 31, and when the second protrusion 22 corresponds to the second groove 32, the second protrusion 22 is embedded into the second groove 32 to form an inverted structure. The assembly of the tap body 30, the bush 20 and the support spring 10 is completed.

The whole assembling process is simple, and the bushing 20 not only can achieve the wear-resisting effect, but also can achieve the good anti-pulling effect.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
