Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a protective cover for a joint used to connect flexible pipes.

0002

[Conventional technology]

Stainless steel spiral flexible pipes are used for hot water supply, air conditioning, etc. Since the outer surface is coated with vinyl chloride, it has corrosion resistance, heat resistance, and weather resistance. It is suitable for hot water supply and air-conditioning piping because it has excellent heat retention and heat retention effects.

0003 Flexible pipes such as those mentioned above can be connected using various types of fittings. will be constructed.

0004

[Problem that the idea aims to solve]

By the way, the fittings used to connect flexible pipes are made of metal, so they cannot be used outdoors etc. If the product is installed in a , there is a problem that the lifespan decreases.

[0005] Also, if the fittings are exposed as they are, it will look bad and the finish of the piping will be unattractive. There is also the problem that.

[0006] Therefore, in order to solve the above problems, this idea was developed to develop flexible pipe joints. It can improve the durability of your hands and improve the appearance of the finished state of the piping. The objective is to provide a protective cover for flexible pipe joints.

[0007]

[Means to solve the problem]

In order to solve the above problems, this invention is used for connecting flexible pipes. The cover that covers the outside of the joint is made of corrosion-resistant and weather-resistant material, and is designed to match the outside shape of the joint. Formed by a pair of single covers that are cut in half, and both covers are folded in half at the bendable part. The two covers have a pair of mating parts on the abutting edges of each cover. This is what was used.

[0008]

[Effect]

A pair of covers that are open on both sides at the bendable part for the fitting that connects the flexible pipe. Close the body by fitting it outward from both sides, and connect the abutting edges of both covers by a pair of fitting parts. When the cover is assembled, the cover covers the entire outer surface of the joint. The protection provided by the cover improves the corrosion resistance and weather resistance of the fitting, making it easier to protect the piping. Improve the finished shape.

[0009]

【Example】

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

0010 As shown in Fig. 1, the flexible tube 1 is made of stainless steel and has a series of arcuate irregularities. It is formed into a continuous spiral, and its outer peripheral surface is covered with a heat-resistant layer 2 such as vinyl chloride. The structure is such that various fittings 3 are required to connect and pipe this flexible pipe 1. are used, and a protective cover 4 corresponding to each joint 3 is also prepared.

[0011] The first example shown in FIGS. 1 to 4 shows a male threaded joint 3a and a protective cover 4 that covers it. The male threaded joint 3a has a pipe 7 threadedly connected to one male threaded cylinder 6 of the joint body 5, On the other hand, externally screw the flexible tube 1 onto the inner peripheral surface of the sleeve 9 inserted into the male threaded tube 8. A threaded groove 10 is formed, and a cap nut 11 externally fitted onto this male threaded cylinder 8 is used to connect the sleeve. The sleeve 9 and the end of the flexible tube 1 are pressed against the packing 12 by pressing the sleeve 9 in the axial direction. A structure that connects the pipe 7 and the flexible pipe 1 in a watertight manner by bringing them into pressure contact with each other. It has become.

0012 The protective cover 4 that covers the male threaded joint 3a covers the outside of this male threaded joint 3a. A pair of single covers 4a and 4a are divided into two on both sides along the axis, and one end is is shaped like a cylindrical case with an opening that fits onto the pipe 7 and the other end fits onto the heat-resistant layer 2. has been completed.

[0013] Both covers 4a, 4a are made of corrosion-resistant and weather-resistant synthetic resin, and are made of a synthetic resin with corrosion resistance and weather resistance. A pair of abutting edges along the line are connected to each other by the bendable part 13, and the bending edge is bent from the open state on both sides as shown in FIG. By folding the parts 13 in half, the two covers 4a and 4a can be opened in half. The edges can be aligned, and the remaining impact between both covers 4a and 4a can be removed. A pair of fitting portions 14 are provided at a plurality of locations on the mating edge.

[0014] As shown in FIG. It is formed by providing a thin-walled portion 16 in the middle of the thin-walled portion of synthetic resin. Therefore, both covers 4a, 4a can be folded in half without any problem.

[0015] In addition, as shown in FIGS. 2 and 3, the fitting portion 14 is formed on the outer surface of the single covers 4a and 4a. protruding pieces 17 and 18 are provided on one side of both protruding pieces 17 and 18, and a shaft 19 is provided on one of both protruding pieces 17 and 18, The other side is formed with a hole 20 into which the shaft 19 fits, and the shaft 19 and the hole 20 are press-fitted. By this, the combined state of both covers 4a and 4a is fixed.

[0016] In addition, as shown in FIG. Projections 21 and 22 are provided that overlap on the inside and outside to improve internal sealing.

[0017] The second example shown in FIG. 5 shows a protective cover 4 used when the joint 3 is an elbow 3b. However, this protective cover 4 is the same as shown in FIGS. 1 to 4 except that the outer shape is L-shaped. This is the same as the protective cover 4.

[0018] Further, the third example in FIG. 6 shows the protective cover 4 used when the joint 3 is a cheese 3c. However, the protective cover 4 is not shown in the figure except that it is formed into two T-shaped parts that fit over the cheese. It is the same as the protective cover 4 shown in FIGS. 1 to 4, and the straight part is the bendable part 13 It is connected and can be opened and closed.

[0019] In addition to the examples shown, there are female threaded joints, sockets, headers, etc. , these protective covers may be formed to match the shape of the joint. Also, the preservation of each example In the protective cover, the inner periphery of the end that fits onto the heat-resistant layer 2 is pressed into contact with the heat-resistant layer 2. It has an acute angle.

[0020] The protective cover of this invention has the above-mentioned structure, and can be flexible using joint 3. After connecting pipe 1 and constructing the pipe, cover the protective cover with a shape corresponding to joint 3. 4, fold the covers 4a, 4a of this protective cover 4 in half at the bendable part 13. while fitting the joint 3 from both sides, and fitting the fitting portions 14 of the abutting edges into each other. When combined, the outside of the joint 3 can be covered with the protective cover 4, which protects the joint 3. In addition to improving corrosion resistance and weather resistance, it is also possible to improve the finished shape of piping. can.

[0021]

【effect】

As described above, according to this invention, the joints that connect flexible pipes have corrosion resistance. Covering the joint with a weather-resistant protective cover effectively protects the joint from wind, rain, and outside air. It can be protected and the durability can be improved even if the joint is placed outdoors.

[0022] In addition, since the joint is covered with a protective cover, the finished shape of the piping is improved. In both cases, the protective cover is a pair of separate covers that can be folded into two at the bendable part. Assemble the two covers together by fitting the mating parts together. As a result, the pair of covers will not be separated, and the installation work for the joint will be easier. I can do my work easily.
