Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a pliers, and in particular, a water pump pliers with a kelep removal function, which is integrally configured with a kelep removal tool for use when replacing a water stop valve (packing top) called a kelep of a water faucet ( Hereinafter, also referred to simply as pliers).

[0002]

[Prior art]

 Generally, pliers are often used for repair and inspection of water faucets. If the packing of the water stop valve (hereinafter referred to as "Kelep") becomes worn and water stops stalling, replace the cap with the pliers and take out the Kelep. The kelep lies deep in the hole where the cap is removed and is very hard to pick by hand. Therefore, in the past, the lifting rod, which was provided so as to project from the top of the kelep, was picked up with chopsticks, tweezers, and tweezers. This work was very troublesome because the lifting rod was round and slippery.

In order to improve this point and to easily take out the kelep by fitting it to the lifting rod, a fitting member made of resin is attached to the tip of the handle of the pliers, and the fitting end is fitted to the tip of this fitting member. A fitting hole is provided, and the diameter of this fitting hole is set to a diameter that allows the Kelep to be picked up by press-fitting it into the Kelep lifting rod from the outside. Pump pliers are proposed in Jpn.

[0004]

[Problems to be solved by the device]

 While the improved water pump pliers described above have excellent functionality, there is still room for further improvement. Moreover, since the Kelep knob lifting portion is provided with a resin fitting member covering the handle extending in the direction of the tip of the handle, if the pliers of the same length are used, the metal part with high rigidity will be the handle. It is much shorter than the full length of the sword, and the handle cannot be gripped firmly at the position farthest from the fulcrum, and the force applied to the handle cannot be transmitted to the chin as a sufficiently strong torque. In other words, if the pliers with the same jaw tightening torque are used, the total length must be longer than that of conventional products. The object of the present invention is to have the same jaw tightening force with the same length as the conventional product, to have the function of taking out the kerep without the need for special parts, and to minimize the cost for adding added value. In addition, it is to provide pliers with a kerep removal function.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a pliers with a kerep removing function according to the present invention has a hole provided at the tip of at least one handle toward the center of the handle, and an outer diameter smaller than the inner diameter of the hole and an inner diameter of the kelep. A vinyl tube that is inserted into the hole and is of a size suitable for picking up the above-mentioned kelep by press-fitting it to the lifting rod from the outside, and the outer diameter is slightly larger than the inner diameter of the hole. Is smaller than the outer diameter of the vinyl tube and larger than the inner diameter of the vinyl tube, and is made up of a metal ring press-fitted to the handle tip side of the hole.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings and the like. FIG. 1 is an explanatory view (plan view) showing an embodiment of the present invention. The larger circle enclosed by the dotted line in the figure is an enlargement of the smaller circle enclosed by the dotted line in the figure, with a part broken away. In FIG. 1, 1 and 2 are a pair of handles of a plier with a kelepp removing function of the present invention. Reference numerals 1a and 2a denote ends of the handles 1 and 2, respectively.

FIG. 2 is a perspective view of the end portions 1a and 2a of the handle according to this embodiment, and the end portion 1a of the handle 1 is particularly disassembled and shown. In the embodiment shown in FIG. 2, the end 2a of the handle 2 is formed in the shape of a minus driver so that it can be used as a driver. However, this portion may have any other shape including an ordinary rod shape. There is no difference. As shown in FIG. 2, a hole 1b is provided in the end 1a of the handle from the end face toward the center of the handle 1. In the hole 1b, a flexible vinyl tube 3 and a vinyl tube 3 are provided. A retaining ring 4 made of metal such as brass is inserted to prevent it from coming out.

The outer diameter of the vinyl tube 3 is slightly smaller than the inner diameter of the hole 1b, and the inner diameter thereof is slightly smaller than the outer diameter of the lifting rod of the kelep so that the kelep can be picked out. The outer diameter of the stop ring 4 is slightly larger than the inner diameter of the hole 1b so that it can be fixed near the outlet inside the hole 1b, and the inner diameter is smaller than the outer diameter of the vinyl tube 3 and larger than the inner diameter.

The vinyl tube 3 and the stop ring 4 are inserted into the hole 1b in this order coaxially with the hole 1b, and the stop ring 4 is press-fitted by a strong external force. Therefore, in the part of the kelepp tool integrated with the handle (the end 1a of the handle 1), the stop ring 4 is fixed to the entrance of the hole 1b, and the vinyl tube 3 is loosely sealed in the stop ring 4. Becomes

In the example embodiments of FIGS. 1 and 2, nothing is covered on the portions of the handles 1 and 2 to be held by the hand, but they may be covered with a suitable resin pipe-shaped covering material. With or without such a coating, as in the case of the water pump pliers proposed in Japanese Utility Model Publication No. 5-11974, the handle is extended with the Kelep knob lifting part made of the resin-fitted member. Since it is not configured in this way, the full length of the highly rigid handle portion can be used for the original purpose of the handle. Therefore, forming the part of the kelep fitting does not reduce the tightening torque of the pliers jaws.

FIG. 3 is an explanatory view showing a situation in which the cap (not shown) of the water faucet 10 is removed and the kelep 11 is taken out using the embodiment example of FIG. In the figure, the cap has already been removed, and the lower opening of the vinyl tube 3 is attached to the upper end of the lifting rod 12 in order to remove the kelep 11 at the part 1a of the kelep removal tool of the embodiment shown in FIG. It is shown in a state just before trying to make the inner surface of the vinyl tube 3 fit along the outside of the lifting rod 12.

FIG. 4 is an explanatory view (enlarged sectional view) obtained by cutting a part of FIG. 3 along the axial direction of the handle 1. When the handle 1 is pushed down toward the kelep 11 from this state, the vinyl tube 3 receives downward repulsive force from the upper end of the lifting rod 12 from the lower end and is pushed downward from the upper end by the bottom surface 1c of the hole 1b. Since the force is applied, an outward lateral pressure force is generated on the pipe wall, increasing both the inner diameter and the outer diameter. Therefore, the inside of the pipe expands, and the lifting rod 12 can be easily inserted.

FIG. 5 is an explanatory view (enlarged cross-sectional view) showing a state in which the handle 1 is pushed down from the state of FIG. 4 until it hits the top 13 of the kelep 11, and is cut along the axial direction of the handle 1. In this state, there is play at the lower end and the upper end of the vinyl tube 3 and no external pressure is applied from anywhere, so the vinyl tube 3 tightens the lifting rod 12 by its original elasticity.

When the handle 1 is lifted from this state, the lower surface of the vinyl tube 3 comes into contact with the retaining ring 4 and receives pressure, but the upper surface is open, so that no outward lateral pressure is generated on the tube wall. Therefore, the force of tightening the lifting rod 12 due to the elasticity of the vinyl tube 3 does not weaken. Therefore, if the handle 1 is pulled up as it is, the kelep 11 can be easily taken out of the water tap 10.

[0015]

[Effects of the Invention] As described in detail above, the pliers with a kelep removal function of the present invention have a hole formed by processing the end of the handle, insert a vinyl tube into the hole, and insert it into the outlet of the hole. Since the part of the kelep remover is constructed with a simple structure that only press fits the retaining ring, it has the same kelp tightening force with the same length while having the function to take out the kelep. There is an effect that a dedicated part is not required and the cost for adding the function can be extremely small.
