Abstract

The utility model discloses a deformed retainer ring, which is characterized in that: the structure of the utility model comprises a ring body, a bridge and a bolt. The bolt passes through an end hole in the ring body and is screwed into another end hole; the bridge is an arc structure; two opening ends in the ring body pass through the two ends of the bridge; a single earhole structure made of the ring body and a double helix ring structure made of the ring body are arranged respectively at the two ends of the ring body; a single helix ring that can spin to the right or to the left is additionally arranged on the ring body. Compared with the conventional fastening mode with a flexible spring tube, the utility model has the advantages of solid fastening mode, uneasy loosing, low cost and long service life.

Description

Special-shaped collar

Technical field

The utility model relates to a kind of fastening various oil pipes, water pipe, the product of tracheae and similar pipeline.

Background technique

At present, spring hose is with its superior performance and obtained a lot of clients' favor working life, as washing machine, and the intake pipe waste pipe of dishwasher, the exhaust tube of smoke extractor, the gas path pipe of various vehicles and machinery etc.But owing to there is spring to be supported on fastening aspect in very big difficulty in the middle of the flexible pipe, general fastening means is difficult to pipe is fastening fully, even also be easy to after fastening come off, therefore exists very big potential safety hazard.

Summary of the invention

The utility model purpose provides a kind of special-shaped collar, with solve spring hose be difficult for being completely fixed with fastening after problem such as be easy to come off.

The structure of special-shaped collar described in the utility model comprises: circle body, and bridge and bolt three parts, described bolt passes circle body one stomidium and is screwed in another stomidium, and described bridge is one section arc-shaped structure, and circle body two opening ends pass the bridge two ends.

Special-shaped as mentioned above collar, described circle body two ends are respectively the duplex helical loop structures that the monaural hole structure made by circle body and circle body are made.

Special-shaped as mentioned above collar, increase on the described circle body left side or dextrorotation to single spiral.

Special-shaped as mentioned above collar, the single spiral on the described circle body are arranged at the medium position away from opening of circle body.

Special-shaped as mentioned above collar, described bolt are the thread tapping bolt.

Special-shaped as mentioned above collar, the periphery of described bridge are concave arc shape groove structure.

Special-shaped collar described in the utility model is compared with the fastening means of traditional spring hose, has fastening means firmly and the characteristics of difficult drop-off, and with low cost, long service life.

Embodiment

Concrete structure of the present utility model is referring to accompanying drawing.In Fig. 1, special-shaped collar comprises: circle body 1, bridge 3 and bolt 2.Described bridge 3 connects the two ends of circle body 1, and the end that bolt 2 passes circle body 1 is screwed into the other end.One end of described circle body 1 is made monaural 5 structures, and the other end is made duplex helical loop 6 structures, and a single spiral 4 is arranged on circle body 1.Described bridge 3 flexibly connects the opening two ends of circle bodies 1, and this bridge 3 is one section arc-shaped structure, and its cross section is a circular arc, forms the groove that cooperates with circle body of being suitable for of its periphery.Bridge 3 two ends are to be suitable for circle body 1 to pass wherein perforation structure.Described bolt 2 is the thread tapping bolt, and the monaural end 5 that this bolt 2 passes circle body 1 is screwed into another duplex helical loop 6 ends.Increase the single spiral 4 of a left side or right two kinds of rotation directions on the circle body.Described single spiral 4 blocks locking fully with the convex portion of spring hose, and the two ends of circle body are more convenient fastening in arriving same groove, and the locking back increases the service life by the elastic force of spiral ring.

Bolt 2 is connected referring to Fig. 1 and Fig. 2 with monaural structure 5.Bolt 2 passes monaural structure 5, is screwed in the other end duplex helical loop 6.Bolt 2 is connected referring to Fig. 1 and Fig. 3 with duplex helical loop 6.The structure of the single spiral 4 of the left and right two kinds of rotation directions that increase on the circle body and position are referring to Fig. 1 and Fig. 4, and this single spiral 4 is the S type as seen from Figure 4, and this single spiral 4 can adopt the structure of a left side or right two kinds of rotation directions.Described bolt 2 is the thread tapping bolt.

The embodiment that Fig. 1 to Fig. 4 provides is the structure of left-handed single spiral 4.The embodiment of the single spiral 4 of dextrorotation sees Fig. 5 to Fig. 8.Because the other parts structure of the single spiral 4 of dextrorotation is identical with Fig. 1's to Fig. 4, just no longer is repeated in this description at this.

Claims
