Description

Hinge with gear transmission structure

Technical Field

The utility model relates to the technical field of hinges, in particular to a hinge with a gear transmission structure.

Background

The hinge is a home decoration fitting, is usually two-fold, consists of a pair of metal or nonmetal blades connected by a shaft pin, and is a part for connecting two parts of an object and enabling the two parts to move.

The existing hinge structure is hinged by adopting more connecting pieces for ensuring stable transmission, wherein the single-axis hinge is a hinge product which is most commonly used in hidden fire door steel frame installation, and the existing single-axis hinge comprises a bearing and a shaft sleeve, and two hinges are propped against each other due to the single-axis rotation process, so that the opening angle of the hinge is between 90 degrees and 135 degrees, and the opening angle has limited influence on daily use.

The problem that the angle of opening of the single-axis hinge is limited is effectively solved by adopting the double-axis linkage structure, but in the installation process of the existing double-axis hinge, more than two hinges can be installed on each door in order to keep stability, and if the rotation angles of the upper hinge and the lower hinge are inconsistent, the condition that the door leaf is inclined can occur.

For example, the Chinese patent with publication number of CN216949963U and patent name of double-shaft rotary arm hinge structure consists of door frame half hinge, rotary arm, door leaf half hinge, shaft 1, shaft 2, planar bearing 1, planar bearing 2, rotary arm limiting buckle plate, guiding rivet column, buckle spring and door leaf decorating sheet. The two ends of the shaft hole 1 and the shaft hole 2 of the rotating arm are provided with a plane bearing 1 and a plane bearing 2, the door frame half hinge is connected with the shaft hole 1 end of the rotating arm through the shaft 1, and the two ends of the shaft 1 are riveted or welded with the outer ends of the shaft holes 3 of the two rolling parts of the door frame half hinge. The door leaf half hinge is connected with the shaft hole 2 end of the rotating arm through a shaft 2, and the outer ends of the two rolling round parts of the door leaf half hinge are riveted or welded and fixed at the two ends of the shaft 2. Two rotary arm limiting buckle plates are arranged on hinge plates of the door frame half hinge, waist-round long holes are formed in the two limiting buckle plates, and the hinge plates are riveted to the door frame half hinge through guide riveting columns. The two limit buckle plates are connected with the V-shaped buckle grooves 1 and 2 on the rotary arms through buckle plate springs, so that the V-shaped buckle heads on the limit buckle plates are automatically buckled in place to clamp the rotary arms for positioning.

For this reason, the problem of how to realize the double-shaft synchronous transmission is a technical problem that needs to be solved by the technicians at present.
