Description

Double slide swing hinge

technical field

The invention relates to a hinge, in particular to a double slideway rotary hinge for connecting rods.

Background technique

The conventional rotary hinge can only allow the rotation between the rods connected by the conventional rotary hinge, which limits the movement of the relative positions between the rods. The double-slideway rotary hinge provided by the present invention removes the restriction that the two rods connected by the conventional rotary hinge can only rotate but cannot adjust the relative position, and realizes that the two rods connected by the double-slideway rotary hinge While doing the rotation, the relative positions of the two rods can be adjusted under the conditions required by the work.

Contents of the invention

The technical problem to be solved by the present invention is: to provide a double-slide rotary hinge, the two rods connected by the double-slide rotary hinge can adjust the relative position of the two rods under the conditions required by the work while rotating. Make adjustments.

Double slideway swivel hinge, characterized by: including slideway modules , slide module and turn module III. The slide module and the slide module Rotate connection through the rotating module III. The slide module Connected to one end of the rotating module III through a bearing I303; the slideway module Connected to the other end of the rotating module III through the bearing II302; the slideway module An upper end cover I101 and a lower end cover I102 are provided, and the upper end cover I101 and the lower end cover I102 are connected by bolts; the rotating module III is provided with a shaft 301 and two rolling bearings I303 and rolling bearing II302 respectively located at both ends of the shaft 301; the shaft 301 The two ends of the rolling bearing I303 and the inner ring of the rolling bearing II302 are respectively fixedly connected; the slideway module An upper end cover II 201 and a lower end cover II 202 are provided, and the upper end cover II 201 and the lower end cover II 202 are connected by bolts.

Through the above-mentioned design scheme, the present invention can bring the following beneficial effects: the double slideway rotating hinge can realize the relative position of the two rods under the conditions required for the work while the two rods are rotating. .
