Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rod tip protection cover for a swinging rod, and is concerned with preventing the tip from breaking when the protective cover is removed.

(Prior art) A guide protrusion window extending to the open end is formed on the side wall of a cylindrical cap body having a closing part at one end and an opening at the other end, and the guide is centrally stored in the inner wall of the opening of the cap body. This is a rod tip protection cover for a swinging rod that forms a base rod clamping part with a diameter smaller than the inner diameter of the main rod clamping part, and a rubber belt is attached to the side wall of this base rod clamping part.
There are No. 28307 and Utsuko No. 56-54797.

(Problems to be solved by the invention) All of the above conventional rod tip protection covers are equipped with a cushioning material such as foamed resin or sponge at the closed end of the cylindrical cap body. The purpose is to reduce the impact applied to the top guide at the tip of the rod, and it does not push the top guide back to the position of the guide protrusion window. Therefore, when the rod tip protection cover is removed, the tip remains inside the closing part. In some cases, this part was gouged out and broke.

(Means for Solving the Problems) The rod tip protection cover for a swinging rod according to the present invention has a closed portion at one end and an open end at the other end. For swinging rods, a protrusion window is formed, and a main rod clamping part with a smaller diameter than the inner diameter of the central storage part is formed on the inner wall of the open end of the cap body, and a rubber belt is attached to the side wall of this main rod clamping part. In the protective cover, an elastic member that can push back the top guide provided at the tip of the tip rod to the guide protrusion window is housed in the closing part.

(Function) As shown in FIG. 2, the top guide 18 of the swinging rod b is placed against the elastic member a, and the base rod 16 is pushed forward to fit the base rod 16 into the clamping part 5 and to tighten its outer periphery. When fastened with the rubber belt 8, the elastic member a is compressed within the closure part 2, as shown in FIG. 3, and the top guide 18 is housed within the closure part 2. In addition, when the rubber belt 8 is removed and the base rod 16 is separated from the clamping part 5 in this state of use, the top guide 18 is pushed back to the position of the guide protrusion window 4 by the elasticity of the elastic member a, and the tip rod 14 is scooped out. The protective cover can be removed without any hassle.

(Embodiment) Next, an embodiment of the present invention will be described based on the drawings. Reference numeral 1 is a cylindrical cap body, which has a closed part 2 at one end and an open end 3 at the other end, and an opening in the side wall. A guide protrusion window 4 extending to the end 3 is formed. 5
is a base rod clamping part formed on the inner wall of the open end 3 of the cap body 1, and the base pole clamping part 5 is formed to have a smaller diameter than the inner diameter of the central storage part 6 of the cap body 1. Reference numeral 7 denotes a stepped portion for inserting the base rod, which is provided between the central storage portion 6 and the base rod clamping portion 5. 8 is the main rod clamping part 5
It is a rubber belt with one end fixed to the outside of the Reference numeral "a" denotes an elastic member built into the closure part 2, including an elastic member 9 made of synthetic resin with a high expansion ratio that is telescopically fitted in the front part of the closure part 2, and a rigid or semi-rigid elastic member fixed to the rear end. It is constituted by a support plate 10 made of synthetic resin. Reference numeral 11 denotes a threading rod whose front end is fixed within the closure part 2, which has a threading hole 12 at its rear end and passes through a through hole 13 formed in the center of the elastic member a. In addition, the code b is the swinging rod, 14 is the tip rod,
15 is an intermediate rod, 16 is a base rod, 17 is a step provided around the front of the base rod 16, 18 is a top guide, 1
Reference numerals 9 and 20 are guides attached to the intermediate rod 15 and the main rod 16.

Since one embodiment of the present invention has the above-described configuration, the threading rod 11 is inserted into the top guide 18 and each guide 19, 20, and the top guide 18 is placed against the elastic member a. , by fitting the base rod 16 into the clamping part 5 while pushing the base rod 16 forward, and fitting the step 17 provided at the tip of the base rod 16 into the fitting step 7, the third As shown in the figure, the elastic member a is compressed in the front part within the closure part 2, and the top guide 18 is inserted into the closure part 2. In this state of use, the rubber belt 8 is removed and the main rod 1 is
6 upwards to separate from the clamping part 5, and remove the main rod 1.
When the step part 17 of No. 6 is removed from the fitting step part 7, the top guide 18 is pushed back to the position of the guide protrusion window part 4 by the elasticity of the elastic member a.
This allows the protective cover to be removed without having to gouge it.

Note that FIGS. 4 and 5 each show another embodiment, in which the configuration of the elastic member a in the previous embodiment is changed. That is, in the case of FIG. 4, a cylindrical body 22 is tightly fitted into the closing part 2 of the cylindrical cap body 1, and a soft rubber sheet 23 is stretched over the rear end, and the top guide 1
8, the soft sheet 23 is bitten into the cylindrical body 22, and the top guide 18 is pushed back to the guide protrusion window 4 by the elasticity of the soft sheet 23 deformed during removal. In the case of FIG. 5, a coil spring 24 is used in place of the elastic body 9 in the embodiments shown in FIGS. 1 to 3.

By using the threading rod 11 as in the embodiments shown in FIGS. 1 to 3 and the embodiment shown in FIG. The fitting of the guide 18 is prevented, and the support plate 10 of the elastic member a prevents the top guide 18 from biting into the elastic body 9. Furthermore, by closing the rear end of the closing portion 2 with the soft sheet 23 of the elastic member a as in the embodiment shown in FIG. be.

(Effects) The rod tip protection cover for a swinging rod according to the present invention has an elastic member inside the closing part of the cylindrical cap body that can push the top guide back to the guide protrusion window. When removing the protective cover, the tip of the tip rod, that is, the top guide, retreats to the position of the guide protrusion window by the elasticity of the elastic member, so that it can be easily removed without damaging the tip.
