Description

An Upper fixing type sink faucet

The present invention breaks away from the conventional mounting method in which a person reaches out and tightens a tightening nut to an extension tube in a narrow space under the sink. In the faucet, an extension tube whose lower end is extended in the form of a fallopian tube is screwed to the faucet body, a tightening ring is keyed to the outside of the extension tube, and the lower end of the tightening ring is opened by the rotation of the tightening ring at the lower part of the extension tube and the extension applied to the bottom surface of the bracket When the ring is inserted and hold the faucet body at the top of the sink with one hand and turn the tightening ring with the other hand, the extension tube is deeply screwed into the faucet body, and the extension at the bottom opens the extension ring, and the opened extension ring is placed under the faucet insertion hole of the sink. The faucet can be firmly attached to the sink by hanging on the anti-rotation bracket mounted on the faucet, and the installation work can be improved very conveniently.

In general, the sink faucet forms a through hole in one side of the sink bowl at the top and bottom of the sink, and the body of the faucet is fixed thereto. It consists of a method of fastening by fastening a tightening nut.

On the other hand, since most of the through holes for installation of the faucet are installed in the rear center or one corner of the sink bowl, the depth of the sink bowl is deep and the sink bowl and the sink wall are close. Not only is it very inconvenient to fasten, but if the tightening nut is not fully fastened, the fixing state of the faucet becomes loose within a short time, resulting in a situation in which the faucet is shaken.

In the prior art, in order to solve the above problems, that is, methods for simply and securely fastening a faucet mounted on a sink or a washbasin have been proposed, which are representative of Patent Documents 1 to 4 below.

The 'faucet fixture' of Patent Document 1 is also for easily fixing the faucet to the sink or washbasin, but this is a method of tightening using a cam-type clamping mechanism. However, there is a problem in that it is impossible to apply when the space between the sink bowl and the wall part is narrow or the depth of the sink bowl is deep.

The 'sink faucet wrench' of Patent Document 2 was developed for tightening the nut in hard-to-reach areas, which is located in a narrow space such as a sink and is difficult to tighten and loosen the nut with the hose installed in the center. It was developed to solve the problem, but there was a problem in that compatibility was difficult when the specifications of the sink faucet were different.

The 'fixture that enables installation of a faucet from the top' of Patent Document 3 is designed to provide easy and convenient assembly of the faucet when the faucet is mounted on a sink or washbasin, which places a ring body on the upper side of the sink and Installation of the faucet is easy because the faucet is fixed on the ring body by fastening the faucet on the ring body by inserting the faucet on the ring body and fastening the headless bolt-type key from the side after fixing the faucet in the state where the fastener is placed on the lower side However, there was a problem that the mounting structure of the faucet was not very strong, and it was not neat in appearance.

In the 'faucet fixing structure' of Patent Document 4, an extension without a thread is formed on the inner circumferential surface of the nut member upward, so that the extension tube can be fixed to the sink even if the nut member is rotated less when screwing the nut to the extension tube of the faucet. However, this also made it difficult to firmly fix the faucet to the sink in a narrow space situation by tightening the nut firmly from the bottom.

In addition, the above problem occurs not only in the sink but also in the washbasin in the bathroom.

In order to solve this problem, the present applicant has developed a 'top fastening sink faucet' in Patent Document 5, which still has to do almost the work of screwing the nut to the male screw part of the extension pipe of the faucet body under the sink, and the last Since the tightening operation was to be finished by turning the tightening ring at the top of the sink, there was still a hassle that the operator had to stretch out his hand under the sink to tighten the nut.

As shown in the accompanying drawings, the sink faucet according to this embodiment includes a faucet body 10 having a water outlet 12 and an opening/closing handle 14 attached to the upper portion and a female threaded portion 16 formed inside the lower end thereof;

an extension tube 20 having a male screw portion 22 formed on the outer side of the upper portion to be screwed to the female screw portion 16 of the faucet body 10 and an extension portion 24 extending in the form of a fallopian tube on the outer side of the lower end;

an anti-rotation bracket 30 fastened from the lower part to the upper part of the faucet insertion hole (2) of the sink (1);

a tightening ring 40 which is inserted outside the extension tube 20 and rotates integrally with the extension tube 20;

an extension ring 50 which is inserted into the lower portion of the tightening ring 40 on the outside of the extension tube 20 and has an extension foot 52 that is spread outward by the extension part 24 of the extension tube 20 radially; In a state in which the anti-rotation bracket 30 is elastically coupled to the faucet insertion hole 2 on the sink (1) lower side, the tightening ring 40 and the expansion ring are mounted on the sink (1) upper side. After inserting the faucet body 10 screwed with the extension tube 20 into which the 50 is inserted into the anti-rotation bracket 30, hold the faucet body 10 with one hand and turn the tightening ring 40 with the other hand. As the main extension tube 20 is deeply screwed to the faucet body 10, the extension 24 at the bottom of the extension tube 20 spreads the extension foot 52 of the extension ring 50 to the outside, and the anti-rotation bracket 30 The faucet body (1) can be easily and firmly installed on the sink (1) by hanging on the faucet.

In this embodiment, the anti-rotation bracket 30 includes a plate body 32 having a right angle surface 31 to prevent rotation by being caught on a corner portion of the sink 1, and the plate body 32 It consists of an insertion hole 34 formed through the inside, and a plurality of elastic hooks 36 radially formed outside the insertion hole 34 and elastically coupled to the faucet insertion hole of the sink 1 .

In this embodiment, the anti-rotation bracket 30 has a right-angled surface 41 to form a right angle with each other to prevent arbitrarily rotating when the faucet insertion hole 2 is generally located at one corner of the sink when mounted on the lower part. However, the present invention does not limit the shape of the anti-rotation bracket 30, and the anti-rotation bracket 30 has a thin thickness of the stainless steel plate forming the sink. When an external force is applied, it acts as a stress dissipation bracket (a kind of 'washer' function) to ensure that the stress is distributed rather than concentrated in the insertion hole.

In this embodiment, the elastic hooks 36 protruding upwards of the anti-rotation bracket 30 are shown to be formed of three, but the present invention does not limit the number of the elastic hooks 36, and in the cross-sectional view For convenience of understanding, it is shown that they are formed at intervals of 90 degrees.

In addition, in this embodiment, the extension ring 50 is radially lower in the state of being caught without interference with the elastic hook 36 of the anti-rotation bracket 30 on the outside of the insertion hole 2 of the sink 1 . When the extension pipe 20 is pulled upwards by the rotation of the tightening ring 40, the extension foot 52 cut into the slit is formed in a structure that is opened while in close contact with the inclined extension part 24 in the form of a fallopian tube.

The anti-rotation bracket 30 and the expansion ring 50 are preferably injection-molded with synthetic resin, but there is no particular limitation on the material and manufacturing method thereof.

In the drawing, reference numeral 42 denotes a fastener serving as a key for integrally coupling the tightening ring 40 to the extension pipe 20 and is caught in the key groove inside the tightening ring 40 , and reference numeral 44 denotes the outside of the tightening ring 40 . As a tool groove formed in the , when a tool such as a wrench is used to rotate from the outside, the tightening ring 40 and the extension tube 20 rotate together.

In the accompanying drawings, the cold and hot water pipes and weights extending under the extension tube 20 of the faucet body 10 are omitted for convenience, and the upper structure of the one-hole faucet is not limited to that shown in the drawings, and the lever (handle) Of course, various types of faucets can be applied, including stepping faucets without ) and sensor-operated faucets.

In addition, in the drawing of this embodiment, the female screw part 16 of the lower part of the faucet body 10 and the male screw part 22 of the extension pipe 20 are shown as single-line screws, but for faster fastening and separation, they may be processed with multi-line screws. Of course it could be.

As shown in FIG. 3, the faucet of this embodiment configured as described above includes screwing the extension pipe 20 to the lower part of the faucet body 10 in advance, and then a tightening ring 40 and an extension ring 50 on the outside of the extension pipe 20. is inserted from the upper side so as not to be separated from the lower part, and then the anti-rotation bracket 30 is coupled to the upper part from the lower part of the faucet insertion hole (2) of the sink (1) so that the elastic hook (36) is inserted into the faucet insertion hole (1). After hanging on the outside of the upper part of (2), the faucet body 1 can be inserted from the upper part of the sink 1, and the extension pipe 20 is screwed to the lower side of the faucet body 1, and this Since the tightening ring 40 and the extension ring 50 are inserted into the extension tube 20, the lower portion of the extension ring 50 together with the extension tube 20 is also coupled to the inside of the faucet insertion hole 2 of the sink 1 is inserted into the insertion hole 34 of the anti-rotation bracket 30 .

In this state, as shown in FIG. 4 , hold the faucet body 10 from the upper part of the sink 1 with one hand so that it does not rotate, and with the other hand, insert a wrench into the tool groove 44 of the tightening ring 40 . When the tightening ring 40 is rotated in the right-hand thread direction by inserting the back, the inner extension pipe 20 coupled to the tightening ring 40 and the fastener 42 rotates in the right-hand thread direction of the faucet body (10). Since it is deeply fastened to the female screw part 16 and pulled upward, the extension part 24 at the bottom of the extension tube 20 radially spreads the extension foot 52 of the extension ring 50, so that the faucet body 10 is placed in the sink. It will be firmly installed in the faucet insertion hole (2) of (1).

As described above, in the sink faucet of the present invention, in a narrow space under the sink, simply turn the tightening ring in the right-hand direction using a wrench at the top of the sink in a state where only the anti-rotation bracket is mounted, and the extension tube is lifted upward. As the extension foot of the extension ring spreads and catches as it is removed, the sink faucet can be securely mounted, and the installation of the sink faucet can be done quickly and easily only by fastening work only at the top of the sink. When the tightening ring is released in the opposite direction, the extension foot is retracted and the faucet body 10 can be removed to the upper side, so that a simple replacement is possible.
