Abstract

The utility model discloses a lower hinged shaft and a lower hinged sleeve of a hinge of a rotary shaft door, which has waterproof performance and has a positioning function when the door is opened to an angle. The upper end surface of the lower hinged shaft is provided with a positioning block, a shaft core and a water-blocking edge, wherein the upper end surface of the shaft core is provided with a V-shaped groove clamp and the center of the shaft core is provided with a shaft hole. The upper end surface of the lower hinged sleeve is provided with a clamping member which is matched with aluminum section, and the periphery of the lower end surface of the lower hinged sleeve is provided with a surrounding edge which is vertical to the end surface. One side of the lower hinged shaft which is provided with the shaft core is a circular arc end and the water-blocking edge is arranged on a half of the periphery of the circular arc end of the lower hinged shaft. The upper end surface of the V-shaped groove clamp is distributed with positioning clamps and an inverted V-shaped protrusive clamping positioning member mutually engaged with the V-shaped groove clamp is arranged in the surrounding edge of the lower end surface of the lower hinged sleeve. The middle part of the clamping positioning member is provided with a cylinder which can be inserted into the shaft hole and is provided with a center hole.

Description

The "down hinge of rotation shaft door hinge and "down hinge

Technical field

The utility model relates to a kind of door hinge, belongs to a kind of the cooperation with aluminium extruded sections to be contained in "down hinge and the "down hinge that rotates the rotation shaft door hinge on the glass door.

Background technology

At present, at hinge that rotates the hinge of adorning on the glass door and hinge cover, continuous variation along with people's aesthetic standards, require the hinge of hinge more and more littler, so the hinge of this door hinge overlap on contour structures and the volume than bigger variation was all arranged in the past with hinge with the area occupied that hinge is enclosed within on the rotation glass door.But people are in daily use, and not only requiring to rotate opening maybe of glass door can close, and require the rotation glass door to open when some angles and can locate, but the hinge of this door hinge and hinge cover can't be realized this function; The hinge of this door hinge and hinge are sleeved on the door in leaching of glass bathroom, water during shower flows to the hinge internal construction and produces ponding along the outer wall of this hinge cover, and constantly outside seepage, long-term use can produce noise, can influence flexibility ratio and the hinge of this door hinge and the application life of hinge cover that door rotates.

Summary of the invention

The purpose of this utility model provides a kind of "down hinge and the "down hinge that can locate, have the rotation shaft door hinge of water resistance when door reaches an angle.

The purpose of this utility model is achieved in that the upper surface of "down hinge establishes locating piece, axle core, dash limit, and the upper surface of axle core is provided with the screens of " V " shape groove, and an axle core is provided with axis hole between two parties; Following strand puts end face and is provided with and the fastener that cooperates aluminium extruded sections, the periphery of following strand cover lower surface is provided with the surrounding edge perpendicular with its end face, "down hinge one side that is provided with a core is an arc end, the dash limit is located on half periphery of "down hinge arc end, in the recessed location screens of the corresponding laying in two upper surfaces of " V " shape groove screens; Be provided with the keeper that holds of " ∧ " shape projection of matching with the screens of " V " shape groove in the surrounding edge of described down strand cover lower surface, be provided with in the middle part that holds keeper and can insert the cylinder that has centre bore in the axis hole.

The utility model has solved ponding in the like product and outside leakage problem; Owing to adopt the lifting structure design, therefore have good positioning performance, door is opened when 60 °, 90 °, 120 ° position and can be located; Because "down hinge adopts third rare nitrile-butadiene-styrene resin (ABS) and polyamide-66 (PA66) injection molded, not only wear-resisting, and appearance can chromium plating, makes that the outward appearance of glass door is more attractive in appearance, also has the level and smooth noiseless characteristics of rotation.
