Abstract
The utility model relates to a connection mechanism, in particular to a quick connection mechanism for steel pipes, which comprises a steel pipe body. One end of the steel pipe body is a reducing section with reduced aperture, the outer diameter of the reducing section is smaller than the diameter of the inner wall of the steel pipe body slightly, a through hole is arranged on the side wall of the reducing section, a U-shaped snap spring made of elastic materials is arranged in the reducing section, and a projection is arranged on one side of the U-shaped snap spring and extends out of the through hole to expose from the outer wall of the reducing section. The quick connection mechanism for steel pipes has the advantages of simple structure, operational quickness, small space occupation, capability of realizing coaxial connection of two steel pipes and the like.
Description
Technical field
The utility model relates to a kind of bindiny mechanism, especially relates to a kind of steel pipe quick-connect machanism.
Background technology
In building operations, because the frequent conversion of floor floor height, interior scaffold standpipe length also will change; Therefore we can not all cut steel pipe as requested, often need plurality of sections of steel pipes be coupled together uses, this just need will be adjacent two save the steel pipes connection; The method of attachment of often using on the building site is directly to connect steel pipe up and down with fastener; Such as the device of Chinese patent 03272950.2 disclosed connection steel pipe, drop into material many, can not make continuous two to save the coaxial connection of steel pipes, and it is bigger to take up room; Operate also more loaded down with trivial detailsly, and adopt the inconvenient construction site little in the operating space.
The utility model content
The goal of the invention of the utility model is to overcome the defective that existing products exists, and realizes steel tube connecting mechanism.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of steel pipe quick-connect machanism comprises the steel pipe body; One end of steel pipe body is the reducing section that bore shrinks, and the external diameter of reducing section is slightly less than the diameter of the inwall of steel pipe own, and the sidewall of reducing section is provided with through hole; Be provided with the U-shaped jump ring made from elastomeric material in the reducing section; One side of U-shaped jump ring is provided with convexity, and convexity passes from through hole, gives prominence to the outer wall in the reducing section.
As preferably, the U-shaped jump ring is processed with steel wire.
The beneficial effect of the utility model is:
The steel pipe quick-connect machanism of the utility model compared with prior art, and is simple in structure, swift to operate, and it is little to take up room, and two joint steel pipes can be accomplished coaxial connection.
Description of drawings
Fig. 1 is the structural representation of steel pipe quick-connect machanism;
Fig. 2 is that the steel pipe of steel pipe quick-connect machanism connects sketch map.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Referring to Fig. 1-Fig. 2: the 1-steel pipe, 101-reducing section, the 102-through hole, 2-U shape jump ring, 201-is protruding, and 3-connects steel pipe.
Fig. 1 is a kind of steel tube connecting mechanism, comprises steel pipe 1, and an end of steel pipe 1 is the reducing section 101 that bore dwindles, and the external diameter of reducing section 101 is slightly less than the diameter of steel pipe 1 inwall own.Be provided with the through hole 102 of a strip at the sidewall of reducing section 101.In addition, be provided with the U-shaped jump ring made from elastic wire 2 in the reducing section 101, a side of U-shaped jump ring 2 is protruding 201.The elasticity of the both sides dependence of U-shaped jump ring 2 jags itself is stuck in the inwall of reducing section 101, and convexity passes in the through hole 102 of strip, gives prominence to the outer wall in reducing section 101.
Fig. 2 is that front and back two joint steel pipes connect sketch mapes; The reducing section of deutomerite steel pipe 1 is inserted in the rear end that connects steel pipe 3; U-shaped jump ring 2 receives the extruding that connects steel pipe 3 inwalls and inwardly bounces back; Because U-shaped jump ring 2 has than strong elasticity, make protruding 201 to be stuck in the inwall that connects steel pipe 3 tightly, thereby two joint steel pipes are connected.
Claims (2)
1. a steel pipe quick-connect machanism comprises the steel pipe body, it is characterized in that: an end of steel pipe body is the reducing section that bore shrinks; The external diameter of reducing section is slightly less than the diameter of the inwall of steel pipe own; The sidewall of reducing section is provided with through hole, is provided with the U-shaped jump ring made from elastomeric material in the reducing section, and a side of U-shaped jump ring is provided with convexity; Convexity passes from through hole, gives prominence to the outer wall in the reducing section.
2. steel pipe quick-connect machanism as claimed in claim 1 is characterized in that: described U-shaped jump ring is processed with steel wire.
