Description

Low door hinge that exposes

Technical Field

The utility model relates to a hardware products field, more specifically says, it relates to a low door hinge that exposes.

Background

At present, a door refers to an entrance of a building or a device installed at the entrance and capable of opening and closing, and the door is an entity dividing a limited space and functions to connect and close the entrance of two or more spaces. The door is also rotatable in addition to the pull-out type. Hinge type door and door frame are often adopted between rotary type door and the door frame and are connected. The failure mode of door hinge mainly is that door hinge rusts, and the switch is difficult, and sound is noisy. Especially in toilets and other wet places, the chance of rusting on the door hinges is very high. The common door hinge is arranged between a door and a door frame, and the area exposed to water vapor is large.

Chinese patent publication No. CN103046820B, the utility model discloses a parcel face hinge in buckled relates to a hinge, is equipped with a plurality of nail holes (9) respectively on one side page or leaf (12) and opposite side page or leaf (14), is equipped with recess B (16) respectively on the downward bending upper portion of one side page or leaf and opposite side page or leaf, the outer end upper portion of one side page or leaf and opposite side page or leaf is equipped with protruding limit (13) that the inboard upper portion has circular arc protrusion (15) respectively, and the sand grip (4) of recess A (3) lower part of one side opposite to two glands (1) are pegged graft with the recess B of one side page or leaf and opposite side page or leaf respectively, and circular arc protrusion (7) of right angle sunken step (6) lower part that two gland outside limits (5) lower parts set up are connected with the protruding lower part joint of circular arc protrusion on one side page or leaf and opposite side page or; according to the invention, the screw cap is hidden by buckling the pressing cover on the leaf at one side and the leaf at the other side, so that the integral decoration aesthetic feeling is further increased. The hinge of the device is protected by the gland, but the hinge joint position which is most prone to corrosion is not protected, and the hinge is very easy to rust.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes present door hinge's rusty not enough easily provides a low door hinge that exposes, sets up in comparatively dry space through the articulated position with the door hinge, has reduced the possibility with the water smoke contact, has reduced rusty possibility, has improved the life-span of door hinge.

In order to solve the technical problem, the utility model discloses a following technical scheme:

Gaps in the hinge cylinder formed by the first fan cylinder and the second fan cylinder in a staggered and matched mode are small, the positioning roller in the hinge cylinder cannot be seen, and the hinge cylinder is more attractive. The hinge structure formed by the mode has the advantages of high strength and small bending moment.

Preferably, a bearing is rotatably mounted between the first and second fan cylinders.

The opening is light after the installation is ensured, and the opening noise is low. The bearing is arranged between the first fan cylinder and the second fan cylinder which are adjacent to each other and is concentric with the first fan cylinder and the second fan cylinder.

Preferably, the door frame leaf is rounded at the bend.

The closed angle that door frame leaf board was buckled is avoided striking on the sealing strip, damages the sealing strip.

The door leaf plate and the door frame leaf plate are not fixed in a top-bottom mode, but are connected in a butterfly mode in a tandem mode, and the hinged connection positions of the door leaf plate and the door frame leaf plate are more, and the connection strength is higher.

Preferably, one end, far away from the hinge barrel, of the door leaf plate is provided with a protruding limiting flanging, and the limiting flanging is arranged on one side, back to the door frame, of the door leaf plate.

And a second sealing strip is arranged at the limiting flanging position, so that the sealing effect can be further improved.

Preferably, the first and second fan cylinders have the same outside diameter.

The same outer diameter can form a smoother hinge barrel and is more attractive.

Preferably, the positioning roller is longer than the hinged cylinder, and two ends of the positioning roller are connected with limiting covers with the outer diameters the same as that of the hinged cylinder.

The positioning roller is inserted in the hinge barrel, one end of the positioning roller is integrally formed with a limiting cover, the other end of the positioning roller is in threaded connection with the limiting cover, or the two ends of the positioning roller are in threaded connection with the limiting cover.

Compared with the prior art, the beneficial effects of the utility model are that: (1) the hinged end is arranged in the dry space, so that the chance of contacting with water vapor is reduced; (2) the coherent sealing strip greatly improves the sealing property and reduces the chance of the hinged end contacting with water vapor; (3) the sealing is carried out by two rows of parallel sealing strips, so that the antirust effect is better.
