Description

Pipeline clamping piece

Technical Field

The utility model discloses be applied to the technical field of clamping piece, in particular to pipeline clamping piece.

Background

Cylindrical workpieces are widely used in various industries, for example: steel pipes, water pipes, gas pipes, etc.; for commonly used bar materials, the simplest way is to use a binding belt to bind, and the applicability of the binding is directly determined by the material of the binding belt, generally a nylon binding belt. Because the plastic head of ribbon and the helicitic texture interlock of bundling the strip, the plastic head that needs to press the ribbon just can untie the ribbon, obviously brings very big inconvenience, otherwise uses the thread trimmer to directly cut off the ribbon, therefore the ribbon is mostly disposable, is directly scrapped after being dismantled for consumptive material volume greatly increased. The section of the cylindrical workpiece in an ideal state is circular, but the actual contour has micro fluctuation, so that unstable clamping is easily caused, and the whole workpiece shakes.

According to a preferable scheme, the pipeline clamping piece further comprises two rotating shafts, second through grooves are formed in the middle portions of two sides of the first clamping ring piece, the two rotating shafts respectively penetrate through the upper end portion of the first clamping ring piece, the second through grooves and the lower end portion of the first clamping ring piece in sequence, and one end, far away from the threaded structure, of the connecting rod rotates around the rotating shafts.

According to the scheme, one end of the connecting rod is hinged in the second through groove through the rotating shaft, and the connecting rod can transversely rotate around the rotating shaft, so that the connecting rod rotates to the first through groove, and clamping and fixing are facilitated.

Preferably, a plurality of positioning holes are formed in the outer side of the first clamping ring piece and are in limit fit with an external positioning mechanism.

According to the scheme, the first clamping ring piece can be fixed on other external positioning mechanisms through the plurality of positioning holes, so that the standardized universality of workpieces is realized.

Preferably, the nut comprises a wing nut.

According to the scheme, the nut is of a butterfly nut structure, so that the nut can be conveniently screwed and fixed or loosened by hand, a special tool is not needed for screwing the screw, and the improvement of the working efficiency is facilitated.
