Abstract
The invention discloses a steel tube connecting structure. The steel tube connecting structure comprises a No.1 steel tube and a No.2 steel tube, wherein the caliber of one end of the No.1 steel tube is reduced, so that a contraction section is formed; the outer diameter of the contraction section is slightly smaller than the inner diameter of the No.2 steel tube; a first through hole is formed in the side wall of the contraction section; a second through hole is formed in the side wall of the No.2 steel tube; a U-shaped clamp spring made of elastic material is arranged in the contraction section; a raised part(s) is (are) arranged on one or two sides of the U-shaped clamp spring; the two sides of the U-shaped clamp spring are clamped with the inner wall of the contraction section; the raised part passes through the outer wall of the contraction section from the first through hole and can be installed with the second through hole in a matched way. The steel tube connecting structure adopts the structure that the U-shaped clamp spring is arranged at the end part of one steel tube, so that the two steel tubes can be rapidly and coaxially connected with each other, and rotation of the two steel tubes can be effectively prevented. The connecting structure is simple, convenient and efficient to operate, easy to machine and manufacture, low in cost and very beneficial to promotion and implementation.
Description
Technical field
The present invention relates to steel pipe docking technique in building field, be specifically related to a kind of steel pipe connection structure.
Background technology
In building operations, due to the frequent conversion of floor floor height, interior scaffold standpipe length also will change, we can not all cut steel pipe as requested, therefore often plurality of sections of steel pipes need to be coupled together to use, this just need to connect two adjacent joint steel pipes, the method of attachment often using on building site is directly to connect upper and lower steel pipe with fastener, drop into material many, can not make to be connected two save steel pipes and coaxially connect, and it is larger to take up room, operate also more loaded down with trivial detailsly, and the inconvenient construction site little in operating space adopts.
Summary of the invention
The object of the invention is for problems of the prior art and deficiency, provide a kind of and can make the coaxial steel pipe connection structure connecting of two joint steel pipes.
Technical scheme is: a kind of steel pipe connection structure, comprise a steel pipe and No. two steel pipes, one end bore of a steel pipe dwindles formation contraction section, and the external diameter of contraction section is slightly less than the internal diameter of No. two steel pipes, the sidewall of contraction section is provided with the first through hole, and the sidewall of No. two steel pipes is provided with the second through hole; In described contraction section, be provided with the U-shaped jump ring of making of elastomeric material, a side or the both sides of U-shaped jump ring are provided with lug boss; The both sides of U-shaped jump ring are stuck in contraction section inwall, and lug boss passes and is positioned at the outer wall of contraction section and can coordinates installation with the second through hole from the first through hole.U-shaped jump ring can be made with steel disc.
The invention has the beneficial effects as follows: the present invention has adopted the syndeton that U-shaped jump ring is set at steel tube end part, make two joint steel pipes can accomplish that rapid coaxial connects, and can effectively prevent that two joint steel pipes from rotating.This syndeton is simple, convenient to operation, easily processing and manufacturing, and cost is low, is beneficial to very much promotion and implementation.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of steel pipe connection status of the present invention.
Fig. 2 is the structural representation of steel tube end part of the present invention.
In figure, 1 is steel pipe, and 101 is contraction section, and 102 is the first through hole, and 103 is capping, and 2 is U-shaped jump ring, and 201 is lug boss, and 3 is joint steel pipe, and 301 is the second through hole.
Detailed description of the invention
Fig. 1 is a kind of steel pipe connection structure, comprises steel pipe 1, and one end of steel pipe 1 is the contraction section 101 that bore dwindles, and the external diameter of contraction section is slightly less than the diameter of steel pipe other end inwall.Be provided with the first through hole 102 of a strip at the sidewall of contraction section.In addition, be provided with the U-shaped jump ring 2 of making of thicker elastic wire in contraction section, a side of U-shaped jump ring is arc lug boss 201.The elastic card of the both sides dependence of U-shaped jump ring jag itself is at the inwall of contraction section 101, and raised arcuate portion passes in the first through hole of strip, gives prominence to the outer wall at contraction section 101.
Fig. 2 is front and back two joint steel pipe connection diagrams, the contraction section of deutomerite steel pipe 1 inserts in the rear end of prosthomere steel pipe 3, the extruding that U-shaped jump ring 2 is subject to prosthomere steel pipe 3 inwalls inwardly bounces back, because U-shaped jump ring 2 has compared with strong elasticity, make lug boss 201 be stuck in tightly the inwall of prosthomere steel pipe 3, thereby two joint steel pipes are connected.
Claims (2)
1. a steel pipe connection structure, comprise a steel pipe and No. two steel pipes, it is characterized in that: one end bore of a steel pipe dwindles formation contraction section, and the external diameter of contraction section is slightly less than the internal diameter of No. two steel pipes, the sidewall of contraction section is provided with the first through hole, and the sidewall of No. two steel pipes is provided with the second through hole; In described contraction section, be provided with the U-shaped jump ring of making of elastomeric material, a side or the both sides of U-shaped jump ring are provided with lug boss; The both sides of U-shaped jump ring are stuck in contraction section inwall, and lug boss passes and is positioned at the outer wall of contraction section and can coordinates installation with the second through hole from the first through hole.
2. according to claim 1, it is characterized in that: U-shaped jump ring steel disc is made.
