Abstract

PURPOSE:To simply engage and fix a protective cover and to achieve labor saving for piping work by connecting a stop piece to a cover main body engaged with a connecting member for covering the connecting member, and providing a fixing means engaging or disengaging with and from a conduit and the other fixing portions on the stop piece. CONSTITUTION:A protective cover 2 is a compact of synthetic resin material, and a stop piece 27 is integrally connected to a cover main body 21 fitted to a bag-like nut 12 through a thin wall hinge portion 25. The cover main body 21 is like a cap fitted to the outer periphery of the bag-like nut 12 from the opening surface side, and is constructed so that a cylinder portion 22 entering the nut inner hole is formed on the base wall, and a taper portion 23 fitted to the enlarged portion of the conduit end portion and a small-diameter projecting shaft 24 entering a conduit inner hole are formed on the forward end of the cylinder portion. The stop piece 26 is forced to rise and fall in the direction parallel or orthogonal to the cylinder portion 22 by the hinge portion 25, and fixing means 27 engaged and disengaged with and from a conduit 11 are provided on the forward end of the stop piece. The fixing means 27 is formed by forming a recess portion 29, one side of which is opened, on a check plate 28, and the recess portion 29 is engaged and disengaged with and from the conduit 11 by rising and falling of the stop piece 26. Thus, a protective cover can be simply attached and detached, and workability can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a protective cover for piping parts, which is applied to air conditioners, hydraulic equipment, air control equipment, etc., and has a pipe connecting member attached to the end of the pipe.

<Prior Art> This type of conduit connection involves attaching a bag nut 31 to the end of the conduit 3 and connecting it to the plug of the mating conduit, as shown in FIG. 4. The bag-shaped nut 31 is equipped with a plug-shaped protective cover 4 that utilizes the thread grooves on the inner surface, and the plug is equipped with a cap-shaped protective cover that utilizes the thread grooves on the outer periphery to prevent dust from entering the pipe inner hole. This prevents intrusion and also prevents damage to the thread groove.

<Problems to be Solved by the Invention> However, in the case of the above-mentioned protective cover 4, since the thread groove 32 is used to fix the protective cover 4, there is a problem that it takes time to attach and remove the cover 4.

Therefore, this invention eliminates the use of screw grooves for attaching the protective cover, and solves the conventional problems by creating a structure in which the protective cover is secured and fixed to the conduit including the bag nut and plug with a single touch operation. The purpose of this invention is to provide a new protective cover that can save labor in piping work.

<Means for Solving the Problems> To explain in detail the present invention to achieve the above object, the present invention is a protective cover for piping parts in which a pipe connecting member is attached to the end of a conduit. The present invention is characterized in that a stopper piece is connected to the main body of the cover that engages with and covers the connecting member, and the stopper piece is provided with a fixing means that engages and disengages from the conduit or other fixed part.

<Function> According to the protective cover configured as described above, the protective cover can be attached and held to the piping component by a simple operation of placing the cover main body over the pipe connecting member and securing the fixing means to the conduit or other fixed part, As a result, the intended purpose of covering and protecting the threaded groove by sealing the pipe hole with the protective cover and preventing dust from entering is achieved.

<Example> The drawing shows a bag-shaped nut 1 forming a pipe connecting member at the end of a conduit 11.
2 shows a situation in which a protective cover 2 according to the present invention is applied to a piping component 1 to which a protective cover 2 is attached.

The protective cover 2 of the present invention is a molded body made of synthetic resin, and has a cover main body 21 that fits onto the bag-shaped nut 12, and a stopper piece 26 that is integrally connected to the cover body 21 through a thin hinge portion 25. .

The cover body 21 has a camp shape that fits around the outer periphery of the bag-shaped nut 12 from the opening side thereof, and has a cylindrical part 22 on the bottom wall that enters the nano I inner hole, and a cylindrical part 22 at the tip of the cylindrical part 22. A tapered portion 23 that fits into the enlarged portion of the end of the conduit is formed, and a small diameter protruding shaft 24 that enters the inner hole of the conduit is formed at the tip of the tapered portion 23.

The stopper piece 26 is undulated by a hinge part 25 in a direction parallel to or perpendicular to the cylindrical part 22, and a fixing means 27 for engaging and disengaging the conduit 11 is provided at the tip of the stopper piece 26.

The fixing means 27 is provided with a stop plate 28 bent in a right angle direction at the tip of the stop piece 26, and this stop plate 28 has four parts 29 each having an opening on one side.
9 is adapted to be connected to and disconnected from the conduit 11.

FIG. 3 shows a protective cover for a plug that is paired with the bag-shaped Nand 12, and has a cap-shaped cover main body 21 that covers the entire threaded groove of the plug 13, and a fixing part 30 that fits and holds the plug main body. figure. A tapered portion 31 is provided on the bottom surface of the cover main body 21 to be joined to the taper end of the plug, and if necessary, elastic rubber is provided to seal the inner hole of the plug. As in the previous example, a stopper piece 26 is connected to the cover main body 21 via a thin hinge portion 25, and a fixing means 27 is provided on the stopper piece 26 to be engaged with and disengaged from the plug body at an appropriate position.

However, when the protective cover 2 of the present invention is used for the piping component 1, the recess 29 is placed on the conduit 11 by fitting the cover body 21 over the bag-shaped nut 12 and then lowering the stopper piece 26. It engages and locks, and the closure of the lumen and the threaded portion are covered. When removing the protective cover 2, the cover main body 21 can be removed by removing the stop plate 28 from the conduit 11.

<Effects of the Invention> As described in 1., the present invention provides a fixing means in which a stop piece is connected to the main body of the cover that engages with and covers the pipe connecting member, and that the stop piece is engaged with and disengaged from a conduit or other fixed part. Since the protective cover is provided with a screw groove, no screw groove is used for attaching the protective cover, which simplifies attachment and detachment work and improves workability.
