Description

Faucet with handle and spindle combined with one touch {WATER TAP TO COMBINE HANDLE AND SPINDLE WITH ONE-TOUCH TYPE}

The present invention relates to a faucet, and more particularly, to a faucet in which a handle and a spindle are combined with one touch to improve assembly.

In general, a faucet is used to conveniently control the flow and stop of water.

1 is a cross-sectional view showing the cross-sectional structure of the conventional faucet 10, Figure 2 is an exploded perspective view showing the coupling structure of the conventional faucet (10).

As shown, the conventional faucet 10 has a main body 11, a disk 12 coupled to the main body 11, a spindle 13 for moving the disk 12 up and down, a handle 15, and a cap ( 16).

The main body 11 has an inlet 11a for supplying water to the inside, an outlet 11b for discharging water to the outside, a barrier rib 11c blocking between the inlet 11a and the outlet 11b, and a barrier rib 11c ) and a water-through hole (11d) formed in, and a coupling pipe (11e) protruding to the upper portion of the body (11).

The disk 12 is disposed in the through hole 11d, and the spindle 13 is coupled to the disk 12. The handle 15 is coupled to the upper portion of the spindle 13 and is operated to rotate by a user. A screw thread 14 is formed on the spindle 13 to transmit the rotation operation of the handle 15 to the vertical movement of the disk 12 so that the disk 12 opens and closes the water-through hole 11d so that water flows into the outlet 11b to be expelled

At this time, the opening degree of the water-through hole 11d is adjusted according to the rotation angle of the handle 15, so that the flow rate at which water is discharged is adjusted.

However, in this conventional faucet 10, the disk 12, the spindle 13, the washer 17, the handle 15, and the cap 16 must be sequentially assembled to the main body 11, so there are many overall configurations. It takes a considerable amount of time to combine, and thus there is a problem in that the manufacturing cost increases.

In particular, in the conventional faucet 10, since the upper cross-sectional shape of the spindle 13 is formed in a rectangular shape, attention is required to properly align the direction when inserting the cap 16 after assembling the spindle 13 to the handle 15 do. If the spindle 13 is not assembled to the handle 15 at an accurate angle, the rotation angle of the handle 15 is misaligned and there is a problem in that the rotation angle is not properly rotated or the rotation angle is limited. Accordingly, the assembly time is further delayed because the workers must check the assembly direction of the spindle 13 one by one and fit the cap 16 to the angle.

In addition, in the conventional faucet 10, the processing start point of the thread 14 formed on the spindle 13 in order to accurately match the height at which the handle 15 is opened or closed should be processed to match the vertex of the square shape on the spindle 13. Therefore, machining precision is required at the time of machining the thread 14 .

However, when there is a change in temperature, such as summer or winter, a difference occurs in the machining position of the screw thread 14 , so that the rotation angle of the handle 15 is changed and accurate flow rate control is difficult.

In addition, the conventional faucet 10 is provided with a separate pusher (not shown) in order to limit the maximum angle at which the handle 15 is rotated, that is, to prevent the handle 15 from being rotated more than once. However, there is a problem in that the overall configuration is increased and the manufacturing cost is increased by adding a separate pusher (not shown).

3 is a perspective view illustrating the configuration of the faucet 100 according to the present invention, and FIG. 4 is an exploded perspective view showing the disassembled configuration of the faucet 100 .

As shown, the faucet 100 according to the present invention is provided on the main body 110 through which water moves, the disk 120 blocking the water hole 114 of the main body 110, and the upper part of the main body 110, A handle 140 that is rotated by the user to control the discharge of water, and a spindle provided between the disk 120 and the handle 140 to convert the rotational motion of the handle 140 into a vertical motion of the disk 120 ( 130).

The faucet 100 according to the present invention eliminates the configuration of the cap 16 as compared with the conventional faucet 10, and enables the handle 140 and the spindle 130 to be assembled in a one-touch manner, thereby reducing the manufacturing cost and assembling It has the advantage of reducing the man-hours.

The body 110 is coupled to a water supply pipe (not shown) so that water can be discharged. As shown in FIG. 7, the body 110 has an inlet 111 for supplying water to the inside, an outlet 112 for discharging the inside water to the outside, and a water between the inlet 111 and the outlet 112. A partition wall 113 for blocking the movement path, a water hole 114 formed in the partition wall 113 to move water, and a coupling pipe 115 formed on the upper portion of the body 110 in a direction perpendicular to the water passage hole 114 ) is included.

The disk 120 is provided in the form of a disk having a larger area than the water-through hole 114 to open and close the water-through hole 114 . The disk 120 is made of a material having elasticity, such as rubber, and the spindle coupling shaft 121 is provided on the upper portion in the vertical direction. The spindle coupling shaft 121 is inserted into the disk coupling hole 132 of the spindle body 131 and the position is fixed.

The disk 120 is coupled to the spindle 130 and moves up and down by the spindle 130 to open and close the water hole 114 . The flow rate of water moving to the outlet 112 through the water-through hole 114 is adjusted according to the height at which the disk 120 is moved upward.

The spindle 130 converts the rotation operation of the handle 140 into vertical movement of the disk 120 . The spindle 130 includes a spindle body 131 coupled to the disk 120 , and a handle coupling head 137 inserted into the handle 140 .

The spindle body 131 and the handle coupling head 137 are integrally processed and manufactured. A disk coupling hole 132 is formed in the lower portion of the spindle body 131 to correspond to the spindle coupling shaft 121 in the upward direction. 7, the spindle coupling shaft 121 is press-fitted to the disk coupling hole 132 so that the spindle 130 and the disk 120 are fixed. Accordingly, a change in the position of the spindle 130 is transmitted to the disk 120 .

The spindle body 131 has a circular cross section, and a screw thread 133 is formed on the outer periphery. The spindle body 131 is accommodated in the coupling tube 115 in a state coupled to the disk 120 . The screw thread 133 is formed on the outer periphery of the spindle body 131 with a predetermined length in the spiral direction, so that the spindle 130 is rotated by the rotation operation of the handle 140 and the inside of the coupling tube 115 is moved up and down.

The handle coupling head 137 is formed with a predetermined length above the spindle body 131 and accommodated in the handle 140 . The handle coupling head 137 according to the present invention is formed in a polygonal shape having a cross section of a hexagon or more, as shown in FIG. 5 .

The conventional faucet 10 shown in FIG. 1 is formed in a form in which the upper end of the spindle 13 has a cross-sectional shape in which an arc is combined with a quadrangle. In this case, since the starting point of the screw thread 14 must fit the vertex of the rectangle, there was a hassle in assembling the spindle 13 by rotating it at an angle of 180 degrees when the operator assembles the spindle 13 to the handle 140 .

On the other hand, in the spindle 130 according to the present invention, since the handle coupling head 137 is formed in a hexagonal shape, when the operator assembles the spindle 13 to the handle 140, it is rotated at an angle of 60 degrees to assemble the conventional spindle ( 13) has the advantage of being able to assemble more easily.

In addition, since the handle coupling head 137 has a hexagonal shape, even if the starting machining position of the screw thread 133 is slightly shifted, the operator can adjust it back and forth within a 60 degree angle, so the processing precision for the screw thread 133 is improved in the conventional faucet (10) It has the advantage that it can be mitigated compared to As a result, the defect occurrence rate is also reduced, and thus the production cost can be reduced.

This advantage can be further improved as the number of the handle coupling head 137 increases, such as octagonal or dodecagonal. However, when the number of squares in the cross-sectional shape of the handle coupling head 137 is increased, there is a risk that the handle coupling head 137 may be idle inside the handle 140, so it is preferably formed in a hexagonal or octagonal shape.

On the other hand, a hook insertion hole 138 is formed on the upper surface of the handle coupling head 137 . As shown in FIG. 7 , a hook receiving hole 138a having a larger inner diameter than the hook inserting hole 138 is formed in the lower portion of the hook insertion hole 138 .

The inner diameter of the hook insertion hole 138 is formed in a range in which the spindle coupling hook 145 can be elastically compressed, and the hook receiving hole 138a corresponds to the width of the spindle coupling hook 145 extended to the initial state. formed to be

Since the hook insertion hole 138 and the hook receiving hole 138a have a difference in inner diameter, a locking protrusion 138b is formed in their boundary area. The spindle coupling hook 145 accommodated in the hook accommodating hole 138a is hooked to the locking jaw 138b, and the position is fixed in a one-touch manner. This will be described in more detail below.

On the other hand, a plurality of packings 135 are coupled to the boundary region between the handle coupling head 137 and the spindle body 131 to prevent water from leaking from the body 110 to the handle 140 side.

The handle 140 is rotated by the user to adjust the amount of water discharged from the body 110 . 5 is a perspective view illustrating a coupling structure between the handle 140 and the spindle 130. As shown in FIG. As shown, the handle 140 is formed in the form of a cylindrical tube with an open lower portion. A plurality of handles are provided on the outside of the handle 140 at regular angular intervals so that the user can easily rotate the handle 140 .

5, a head coupling hole 143 is provided in the upper inner side of the handle 140 to correspond to the shape of the handle coupling head 137, and a pair of spindle coupling hooks ( 145) is provided. The head coupling hole 143 is provided in a hexagonal shape to correspond to the hexagonal handle coupling head 137 in a preferred embodiment of the present invention, but this is an example and is provided to correspond to various shapes of the handle coupling head 137 .

The spindle coupling hook 145 is elastically fitted into the hook insertion hole 138 of the handle coupling head 137 which is integrally coupled to the upper surface of the handle 140 downwardly and is inserted into the head coupling hole 143 . A pair of spindle coupling hooks 145 are provided on both sides.

When the pair of spindle coupling hooks 145 are inserted into the hook insertion hole 138, they are compressed to fit the inner diameter of the hook insertion hole 138, and the handle coupling head 137 is completely inserted into the head coupling hole 143. When fitted, a pair of spindle coupling hooks 145 are inserted into the hook receiving holes 138a. At this time, a pair of elastically engraved spindle coupling hooks 145 are unfolded to their initial state, and hook heads 145a formed at the lower end of each spindle coupling hook 145 are hooked on the locking jaws 138b.

That is, as shown in Figure 7, when the user press-fits the spindle 130 into the head coupling hole 143 of the handle 140, the spindle coupling hook 145 is elastically folded or unfolded, and the hook receiving hole 138a. The position is fixed by being caught on the locking jaw (138b) of the. As a result, compared to the conventional faucet 10, the process of coupling the separate cap 16 to the spindle 13 at an angle through the upper part of the handle 15 is omitted, so that the overall assembly time of the faucet can be significantly reduced. There are advantages.

On the other hand, (a), (b) and (c) of Figure 6 is an exemplary view showing various modifications of the spindle coupling hook (145', 145", 145"'). As shown, the spindle coupling hook is provided in a form in which a pair of engaging hooks and a coupling bar are coupled as shown in (a) of FIG. 6, or is formed in a triangular shape as shown in (b) of FIG. , may be formed in the form of a protrusion in the oblique direction as shown in (c) of FIG.

In addition to this, the spindle coupling hook may be provided in various forms that can be engaged with the engaging projection (138b).

Meanwhile, the spindle coupling hook may be integrally manufactured on the upper surface of the handle, or may be separately manufactured and then fixedly coupled to the handle by welding or bonding.

On the other hand, the outer periphery of the coupling pipe 115 of the main body 110 is provided with a main body locking jaw 116 to protrude outward, and on the inner wall surface of the handle 140, a handle locking jaw 147 as shown in FIG. 5 . ) is provided to protrude inward in the radial direction.

The body locking jaw 116 and the handle locking jaw 147 abut against each other when the handle 140 is rotated at the maximum rotation angle, and the handle 140 is prevented from being rotated further. That is, the main body locking jaw 116 and the handle locking jaw 147 serve as a stopper of the conventional faucet. Therefore, the faucet 100 of the present invention has the advantage that the body locking jaw 116 and the handle locking jaw 147 can perform a function of limiting the maximum rotation angle of the handle 140 without a separate locking member.

An assembly process and a use process of the faucet 100 according to the present invention having such a configuration will be described with reference to FIGS. 3 to 7 .

As shown in FIG. 4 for assembling the faucet 100 of the present invention, the body 110, the disk 120, the spindle 130, and the handle 140 are prepared. The operator inserts the spindle coupling shaft 121 of the disk 120 into the disk coupling hole 132 of the spindle 130 to fix the disk 120 to the spindle 130 .

Then, the spindle body 131 of the spindle 130 is inserted into the coupling tube 115 of the body 110 . Thereby, the disk 120 blocks the water hole 114 of the main body 110 .

In this state, the operator inserts the handle 140 into the handle coupling head 137 of the spindle 130 . The operator rotates the handle 140 to the left and right to insert the hexagon-shaped handle coupling head 137 into the head coupling hole 143 . When the handle coupling head 137 is inserted into the head coupling hole 143, the spindle coupling hook 145 located in the head coupling hole 143 is accommodated in the hook receiving hole 138a through the hook insertion hole 138, and the engaging projection (138b) is elastically engaged.

Thereby, the position of the handle 140 and the spindle 130 is conveniently fixed in a one-touch manner.

6 is a cross-sectional view of the assembled faucet 100 . Since the disk 120 blocks the water-through hole 114 , the water introduced into the inlet 111 does not move to the outlet 112 .

In this state, when the operator rotates the handle 140 , the thread is rotated by the rotation angle and the spindle 130 is moved upward in the coupling tube 115 . As a result, the disk 120 coupled to the lower portion of the spindle 130 is also moved upward and the water-through hole 114 is opened. Then, the water is moved through the open water hole 114 is discharged to the outlet (112).

At this time, if the rotation angle of the handle 140 is large, the height at which the disk 120 moves upward is increased, and the opening degree of the water passage hole 114 is widened, so that the flow rate of the discharged water is increased.

On the other hand, if the handle 140 is rotated in the opposite direction, the spindle 130 is lowered and the disk 120 blocks the water hole 114 to prevent water from being discharged.

As described above, the faucet according to the present invention has the cross-sectional shape of the upper end of the spindle in a polygonal shape of hexagon or more, so that it can be easily assembled with the handle. In addition, the spindle coupling hook provided at the top of the handle without a separate cap is elastically hooked to the top of the spindle, so that the handle and the spindle can be assembled in a one-touch manner.

Accordingly, the faucet according to the present invention has the advantage of reducing the manufacturing cost by simplifying the overall configuration and simplifying the assembly process compared to the conventional faucet.

In addition, as the spindle head is manufactured in a polygonal shape, there is an additional advantage of reducing the precision of the threading of the spindle.

In addition, there is an effect that the maximum rotation angle of the handle can be limited by the structure of the main body locking jaw and the handle locking jaw without a separate locking member.

The embodiments of the faucet of the present invention described above are merely exemplary, and those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications and equivalent other embodiments are possible therefrom. will be.
