Description

[Detailed description of the invention] (a) Industrial application field This invention relates to an improvement of a drain pipe cleaning dropper.

(b) Conventional technology The conventional method for attaching a handle to a down-bowl-shaped rubber dropper was to fix it by nailing it into the handle, and tweezers for handling dirt etc. during cleaning work were required separately. I prepared it and carried it with me.

(c) Problems to be solved by the invention The conventional method of attaching a handle to a rubber dropper by driving a nail into the handle is rather cumbersome, so it cannot be replaced with a screw-in method. Various attempts have been made to do this, but since the handle is made of flexible and stretchable rubber, it has the disadvantage that even if it is screwed in, if it is pulled too hard, the rubber part will stretch and fall off.

In addition, tweezers are often required when penetrating and cleaning clogged drain pipes in toilets, etc. Although they are one of the tools that must be carried at all times, carrying them around is extremely troublesome.

(d) Means to solve the problem If a screw thread is provided inside the cylindrical handle of a down-bowl-shaped rubber dropper, and the threaded rod 4 at the tip of the handle is screwed into this thread, it will not be possible to force the dropper upwards as it is. When it is pulled, the handle part of the rubber stretches and bulges around it, causing the screw thread to come off and fall out.In order to prevent this, in this invention, a ring band 7 is wrapped around the cylindrical part 6 to prevent the rubber from expanding. By doing so, the engagement of the screw threads is prevented from coming off, and the handle rod is prevented from falling off from the dropper.The tweezers, which are inconvenient to carry, are always kept in the tweezers storage groove 1 provided in the center of the handle rod. The conventional problems have been solved by configuring the device so that it can be inserted and left in place, and then taken out and used as needed.

(e) Function This device wraps the outer periphery of the cylindrical handle part 6 with a ring band 7, so that it will not fall off even if it is strongly pulled upward during work. This is because the screw thread carved inside is firmly inserted between the outer ring band 7 and the screw rod 4 at the tip of the center rod, and there is no room for the rubber to extend outward.

Also, since the tweezers, which are inconvenient to carry, are always stored in the center of the handle, there is no need to worry about tweezers.

(Example) Next, an example of this invention will be described in detail based on the drawings.

A tweezers storage groove 1 is provided in the center, and a tweezers 2 are removably stored in the handle 3. A threaded rod 4 for attaching a dropper is provided at the lower end of the handle 3, and a dropper 5 made of flexible and stretchable rubber or plastic is provided in the shape of a bowl.
The outer periphery of the upper end cylindrical part 6 is surrounded by a ring band 7, and a thread 8 is carved on the inner peripheral surface of the central handle part, and the above-mentioned screw rod 4 is screwed into this to connect the drain pipe cleaning. It is a dropper for use.

(f) Effects of the invention Since this invented dropper has the structure described above, there is no need to assemble it with nails, etc., as in the past.
Assembly is completed by simply placing the ring 7 over the cylindrical part of the dropper and screwing the screw at the tip of the handle into the handle of the dropper.Therefore, there is no need for nails, hammer anvils, etc. It is easy to assemble and does not require any difficult techniques, so when shipped from the factory, the handle and dropper part are not assembled and can be packed and sold by simply screwing the handle at the end, which reduces freight charges. It saves money.

In addition, the dropper part and handle part can be carried separately, assembled and used at the work site, and then disassembled and taken with you when the work is completed, which is very convenient when moving.

In addition, in the conventional method of fixing the handle part with nails, all the force was applied to one nail, which caused the rubber in this part to break and break. Since this is a method of fixing by tightly interlocking the threads of the joints, no excessive force is applied, so there is no chance of damage at the joints.
