Description

{WRENCH FOR CHANGING WASHBOWL FAUCET AND SINK FAUCET}

More particularly, the present invention relates to a wrench for replacing a sink faucet and a pop-up drainage pipe of a sink, more specifically, it is capable of easily tightening and loosening in a narrow space below a sink, To a wrench after replacement.

Generally, bolts and nuts are used to assemble various machines, and the sizes of bolts and nuts vary widely depending on the type and position of the machines to be assembled. Also, such bolts and nuts use wrenches for engagement and disassembly, and the locations and clearances where the bolts and nuts are provided affect the use of the wrenches.

FIGS. 1 and 2 are views for explaining a state in which a general sink receptacle is fixed by a fixing nut, and FIGS. 3 and 4 are views for explaining a state in which a general sink receptacle is fixed by a hand nut.

1 and 2, the sink receptacle 2 is installed in the sink 3. The screw portion formed at the lower portion of the sink receptacle 2 passes through the hole formed in the sink 3, The fixing nut 5 is fixed to the sink base 3 by fastening the fixing nut 5 to the threaded portion in the sink base 3 while being installed inside the sink base 3. The fixing nut 5 may be a hexagonal nut and is composed of an upper flange portion 5a and a lower hexagonal body portion 5b. When the sink receptacle 2 is to be replaced, the sink receptacle 2 can be disassembled by unscrewing the fixing nut 5 coupled to the threaded portion and separating it from the threaded portion.

On the other hand, in case of the sink (3), it is difficult to dismantle the sink faucet (2) due to the space limitation. Specifically, a lower portion of the sink receptacle 2 and a fixing nut 5 are located in a narrow space between the sink bowl and the side wall of the sink 3, and a plurality of water receiving hoses 6 are provided below the sink receptacle 2, There has been a problem of ineffective workability in tightening or dismounting the fixing nut 5 by using a tool such as a wrench or a spanner.

In order to solve such a problem, a so-called hand nut 7, which is easy to grasp in a narrow space with a long length, has been proposed and popularized instead of the fixed hexagon nut 5 as shown in Figs. 3 and 4 . On the other hand, the hand nuts (7) also have a deep working space and are difficult to approach the operator's hands when the depth of the sink bowl is deep. Even if the hand reaches, the hand nut (7) There is a problem that there is a considerable difficulty.

In addition, there is a problem that it is inconvenient to prepare a tool suitable for the model by identifying the model name when replacing the sink faucet (2) because there are various types of sink nut. Recently, a hexagonal nut 5 as described in FIGS. 1 and 2 is also used for the automatic pop-up drain pipe in the washstand, and the same operation is also difficult in the case of replacing the pop-up drain pipe of the sink.

Accordingly, various studies are being conducted on wrenches that can flexibly cope with various shapes of nuts, and can efficiently replace the sink faucet and the washtub pop-up drain pipe even though there is a space limitation.

The handle portion 140 may be integrally formed with the wrench body 110 by injection of a rubber insert. By using the rubber insert injection, the wrench body 110 and the handle 140 formed of different materials can be integrally formed. The thermoplastic polyurethane is melted by heat in the process of injecting the rubber insert so that the step 113a of the concave portion 113 is melted by heat Can be inserted into the groove (113b) while canceling. The thermoplastic polyurethane is hardened in the shape of the groove 113b after the injection of the rubber insert is finished and is fixed in the groove 113b due to the shape limitation of the groove 113b having a smaller entrance than the inside . The handle portion 14 is integrally formed with the wrench body 110 by injection of a rubber insert and can be more firmly fixed by the groove 113b.

Hereinafter, another embodiment of the present invention will be described with reference to FIG. Except for the contents to be described later, the contents similar to those described in the embodiments described with reference to Figs. 5 to 10 will not be described in detail.

11, the wrench body 210 according to the present embodiment includes a first wrench 220 integrally formed at one end of the wrench body 210 and a second wrench 220 formed at an approximate center of the wrench body 210 (Not shown). The handle portion 240 may be a portion where a hand of an operator is fixed and a force is applied by the wrench in a process of operating the wrench.

The handle 240 according to the present embodiment may include one or more projections 241 and 242 projecting outwardly. The protrusions 241 and 242 may include a first protrusion 241 and a second protrusion 242 having different heights and sizes. The first protrusion 241 may have a height larger than that of the second protrusion 242 and may have a large area. The contact area of the first protrusion 241 with the operator's hand is increased to prevent the work efficiency from being hindered such as the wrench being slipped when the worker operates the wrench. The second protrusions 242 may be provided between adjacent portions of the first protrusions 241 and may have a smaller and higher area than the first protrusions 241. The second protrusion 242 may give an acupressure effect to the operator's hand to help blood circulation of the hand of the operator and to reduce work fatigue.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
