Description

Door hinge convenient to dismouting

Technical Field

The utility model relates to a door hinge especially relates to a door hinge convenient to dismouting.

Background

The conventional door hinge for a door body generally includes upper and lower leaves having rotation shaft holes in a symmetrical structure to each other, wherein the upper leaf is installed on a door panel, the lower leaf is installed on a door frame, and a plurality of installation holes are formed in the upper and lower leaves to facilitate installation, and a rotation shaft penetrates the rotation shaft holes in the upper and lower leaves simultaneously to connect them together, and is riveted at the outer ends of the rotation shaft holes to be positioned on the upper and lower leaves. Because the two ends of the rotating shaft for connecting the two blades are fixed in the rotating shaft hole, the two blades are not easy to split, and the upper blade and the lower blade can only be simultaneously disassembled from the door plate and the door frame during disassembly, so the traditional door hinge has the defect of inconvenient disassembly and assembly.

For example, a hinge structure disclosed in a Chinese patent invention with application number ZL96211963.6 (publication number CN2299922Y) of an automatic return door hinge structure, a hinge structure disclosed in a Chinese utility model with application number ZL02205657.2 (publication number CN2526432Y) of a spring door hinge structure, and a hinge structure disclosed in a Chinese utility model with application number ZL03268199.2 (publication number CN2632252Y) of a folding door hinge structure,

the various door hinges to which the above-mentioned patent application relates all have certain advantages, but they all have the disadvantage of inconvenient disassembly and assembly.

Disclosure of Invention

The utility model aims to solve the technical problem that a hinge that simple structure is reasonable, convenient to use, with low costs, the outward appearance is big is provided to above-mentioned prior art current situation.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a hinge convenient to dismouting, includes that one has the last blade that rotates the shaft hole, and one has the lower blade that rotates the shaft hole down, rotates upward and links to each other through the pivot between shaft hole and the lower shaft hole and make the last blade and lower blade relatively rotate its characterized in that: the pivot spacing be in lower shaft hole in, the lower shaft hole that exposes is simultaneously outward seen to the at least one end of pivot, go up the pivot shaft hole movable sleeve that upwards rotates on the blade and locate the pivot that exposes lower shaft hole.

The upper end and the lower end of the rotating shaft are exposed out of the lower rotating shaft hole. Therefore, the upper blade can be arranged at the upper part or the lower part of the lower blade, namely, the door hinge can be arranged at the left side or the right side of the door frame, and the door hinge is more convenient to install.

The cross section of the lower blade is U-shaped, and the lower shaft hole is arranged on the outer side of one horizontal part of the lower blade. As is well known, because the upper blade and the lower blade of the conventional door hinge are both plate-shaped, one of the blades of the conventional door hinge is installed on the side end surface of the door frame, and the rotating shaft hole on each blade is positioned on the outer side of each blade, each rotating shaft hole is exposed outside the door body in the door closing state, and lawbreakers are easy to damage the hinge on the outside, and the use is unsafe. And adopt aforementioned lower blade structure, the junction of upper and lower blade stretches into the door internal and hide during the installation, and whole hinge is all hidden at the door internal when closing the door promptly, prevents effectively that lawless persons from externally destroying hinge structure and opening the door, improves the security of hinge, still can ensure simultaneously that the door body that uses this hinge is more pleasing to the eye.

The middle part of the rotating shaft is provided with two annular clamping grooves which are arranged at intervals, and under the condition that the rotating shaft is inserted in the lower rotating shaft hole, the two annular clamping grooves are respectively clamped with a clamping ring so as to limit the rotating shaft in the lower rotating shaft hole up and down. The structure is used for limiting the rotating shaft in the lower rotating shaft hole, and other limiting modes can be adopted.

In order to facilitate the installation of the hinge, the upper blade is provided with a plurality of installation holes, and the other horizontal part of the lower blade is provided with a plurality of installation holes. Therefore, the upper blade and the lower blade can be in height with the door frame or the door body through the screws.

Compared with the prior art, the utility model has the advantages of: the pivot is spacing be in lower shaft hole in, the at least one end of pivot exposes lower shaft hole simultaneously and be connected with last blade on last shaft hole, to fixing lower blade and door frame during the equipment, establish the pivot pot head of going up the blade in exposed pivot again, fix last blade and door body at last, accomplish the installation promptly, when the door body needs to be changed or when the reverse installation of door body, only need to pull up the blade and door body apart, alright easily take off last blade from the pivot, dismantle convenience fairly.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Fig. 1 to 4 show a preferred embodiment of the present invention.

A door hinge convenient for disassembly comprises an upper blade 1 with an upper rotating shaft hole 11 and a lower blade 2 with a lower rotating shaft hole 21. Wherein,

the base body of the upper blade 1 is a metal sheet-shaped piece, one side edge of the metal sheet-shaped piece is curled to form an upper rotating shaft hole 11, and the upper blade 1 is provided with two mounting holes 12 so as to facilitate the mounting of the upper blade 1 on a door body.

The base member of lower blade 2 is the plate type spare that is the U type for buckling, it has mounting hole 22 to open on one of them horizontal part of this lower blade 2, so that install this lower blade 2 on the door frame, the outside limit of another horizontal part of lower blade 2 is curled and is processed and form lower shaft hole 21, install under the state of door frame at lower blade 2, the vertical portion of lower blade 2 is located the inboard of door frame, lower shaft hole 21 is located the outside of door frame, the higher authority that is equipped with the horizontal part of lower shaft hole 21 is less than the higher authority that opens the horizontal part that has mounting hole 22, the lower level that is equipped with the horizontal part of lower shaft hole 21 simultaneously is higher than the lower level that opens the horizontal part that has mounting hole 22, and mounting hole 22 sets up both ends about.
