Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The present invention is based on wedge-shaped self-locking pre-tightened steel pipe butt fasteners, such as figure 1 , 2 As shown, including the steel pipe socket part and the steel pipe fastening part.

[0018] The steel pipe sleeve part includes a steel cylinder 7, the inner cylinder wall in the middle of the steel cylinder 7 is provided with several shoulders 6 along the circumference, and the cylinder body of the steel cylinder 7 is provided with an opening 11 in the axial direction, and the opening 11 is connected to the steel pipe fastening part .

[0019] The shoulders 6 are arc-shaped protrusions arranged inside the steel cylinder 7, the number of the shoulders 6 is greater than two, and the pipe fittings that can be socketed in the steel cylinder 7 are more reliable.

[0020] The fastening part of the steel pipe includes a...

Abstract

The invention provides a steel pipe butting fastener based on wedge-shaped self-lock pre-tightening. The steel pipe butting fastener comprises a steel pipe sleeving part and a steel pipe fastening part, wherein the steel pipe sleeving part comprises a steel cylinder, blocking shoulders are circumferentially arranged on the inner cylinder wall in the middle of a body of the steel cylinder, circular rings with different thicknesses are punched on the surface of the body of the steel cylinder, and an opening is axially formed in the body of the steel cylinder and is connected with the steel pipe fastening part. Through matching of wedge-shaped groove blocks and rivets, the self-lock function of each wedge-shaped groove block is realized, butting steel pipes located at the pipe sleeving part are locked, butting of the steel pipes is completed, the operation is simple, convenient and efficient, and meanwhile, the safety performance is higher.

Description

technical field [0001] The invention belongs to the technical field of engineering construction equipment and relates to a steel pipe butt fastener based on wedge-shaped self-locking pretightening. Background technique [0002] At present, the steel pipe butt joint fasteners used in the construction industry are basically two halves of the split structure. When in use, workers need to manually connect and pre-tighten the two halves of the fasteners through bolts. The operation efficiency is low and the safety performance is low. And in actual use, problems such as thread corrosion and nut loss often occur. Contents of the invention [0003] The object of the present invention is to provide a steel pipe butt joint fastener based on wedge-shaped self-locking pretightening, which solves the problems of low operation efficiency, poor safety and inconvenient use of steel pipe butt joint fasteners in the prior art. [0004] The technical solution adopted in the present inventio...
