Hinge device capable of locking buffer switch position

Abstract

A hinge device capable of locking a buffer switch position comprises a movable hinge cup and a hinge joint arm, wherein the movable hinge cup and the hinge joint arm are in hinge joint connection. A buffer mechanism is arranged on the movable hinge cup, the hinge joint arm at least acts on the buffer mechanism when a hinge is closed, the buffer mechanism comprises a damper and a gland, the damper is arranged in a concave position of the movable hinge cup, the gland is arranged on the damper, and the damper can slide back and forth on the gland. A damp switch component is arranged on the gland in a rotating or swing mode, and the limiting and / or restoration of a buffering stroke of the damper are / is achieved by rotating or swinging the damp switch component when the hinge is opened and / or closed. The gland and / or the damp switch component are / is made of plastic having certain elasticity, a limiting part is arranged between the gland and the damp switch component, and the damp switch component achieves position locking and the limiting and / or the restoration of the buffering stroke of the damper through the limiting part. The hinge device capable of locking the buffer switch position has the advantages of being simple and reasonable in structure, reliable in performance, long in service life, low in manufacturing cost, fast and convenient to adjust and accurate and firm in locating.

Description

technical field [0001] The invention relates to a hinge, in particular to a hinge device capable of locking the position of a buffer switch. Background technique [0002] The Chinese patent literature number is CN201339380, which discloses a hinge on January 9, 2009, which includes a door box, a connecting rod, a hinge arm, a shift arm, a base, a buffer, a torsion spring, a link and a lever drive piece, and the link The device is a fan-shaped structure, which has a center hole and 3 peripheral holes, through which the center hole is movably connected to the hinge arm for positioning, and 1 peripheral hole is movably connected to the piston rod end of the buffer, and the remaining 2 peripheral holes are equipped with shafts. The lever driving piece is provided with an end hole and a middle hole, and the other end opposite to the end hole is provided with two fork mouths, and the lever driving piece is movably connected to the hinge arm through the middle hole, so that the two...

AI Technical Summary

Problems solved by technology

It is said that the structure is simple, the performance is reliable, and the use is flexible. However, due to the effect of the buffer, this structure requires a large force to open or close the door body, which may easily cause damage to the handle on the door body or the door body cannot be closed properly. And the hinge of this structure is not convenient enough to use, and the buffering time of the buffer cannot be adjusted, which cannot meet the needs of users
