The present invention relates to a hinge for a door, and more particularly, a fitting member is inserted into an upper end and a lower end of a rotating member fastened by a pin to a space portion of a fixing bracket to block a gap between the bracket and the rotating member so that the upper and lower parts of the rotating member are closed. A hinge for a door to block flow.

In general, the door hinge is installed in various doors so that the door can be rotated, and a fixed bracket fixed to the door frame and a fixed member fixed to the door and fitted to the fixed bracket and the fixed bracket and the rotating member It is installed to penetrate and consists of a pin for supporting the rotatable member.

However, in the case of a conventional door hinge, a gap is generated between the fixing bracket and the rotating member when the fixing bracket and the rotating member are fastened with a pin, and the rotating member flows up and down about the pin. Thus, the door in which the pivot member is fixed also has a problem that the flow occurs up and down.

Therefore, the present invention for solving the above problems is to provide a door hinge for preventing the flow of the rotating member and the door fixed to the rotating member by blocking the gap between the fixing bracket and the rotating member.

The present invention for achieving the above object is installed in the door frame and the upper and lower ends of each of the protrusions are formed in the center and the fixing bracket is formed in the center, the rotating member is installed in the door and fitted to the space, In the hinge for the door is configured to penetrate the fixing bracket and the rotating member to be fixed and at the same time the rotating member is rotatably supported, wherein each of the protrusions are formed on the same line and connected to each other and formed through the hole When the fixing member is combined with the fixing bracket, the rotating member is formed on the same line as the hole and is connected to each other. The holes are formed through the pins, and the upper and lower ends of the holes are respectively provided. Is formed, the stepped to block the gap generated when the fixing bracket and the rotating member is coupled A member fitted to help load characterized.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is an exploded view showing the configuration of the door hinge of the present invention, Figure 2 is a cross-sectional view showing a coupling configuration of the door hinge of the present invention.

Referring to FIGS. 1 and 2, the door hinge of the present invention is largely fitted to the rotating member 20 and the fixing bracket 10 and the rotating member 20 fitted to the fixing bracket 10 and the fixing bracket 10. It consists of a pin 30 installed through.

The fixing bracket 10 is a means that is installed in the door frame for supporting the door, each protrusion 12 is formed at the top and bottom, the space portion 14 is formed in the center.

Each of the protrusions 12 is formed with holes 16 penetrating the inside and positioned on the same line with each other.

On the other hand, the rotating member 20 is installed in the door and is fastened to the space portion 14 to rotate the pin 30 to the axis and rotates the door as a means for rotating the door 22 is formed in the center Steps 24 are formed at upper and lower ends of the holes 22. At this time, the hole 22 is preferably located on the same line as the hole 16 formed in the projection 12 when the rotating member 20 is fastened to the bracket (10).

On the other hand, the fitting member 26 is fitted into the stepped portion 24 formed on the upper and lower ends of the hole 22, respectively. The fitting member 26 is a means for blocking the gap (K) generated in the bracket 10 and the rotating member 20, the head portion 18 is formed on the upper end of the cylindrical shape is empty, the lower end, The insertion portion 28 having a diameter smaller than the head portion 18 is integrally formed. At this time, the insertion portion 28 is fitted to the step 24 formed on the upper and lower ends of the rotating member 20, the head portion 18 is exposed to the upper and lower ends of the rotating member 20, respectively, the bracket ( The head portion 18 blocks the gap K generated between the rotating member 20 and the rotating member 20 to prevent the up and down flow of the rotating member 20. That is, when the rotating member 20 is fastened to the bracket 10, the head portion 18 is in close contact with the upper and lower surfaces of the space portion 14 to block the gap (K) to the rotating member ( It is to prevent the flow of 20 and to block the flow of the door fixed to the rotating member (20). In addition, the fitting member 26 is inserted into the stepped portion 24 of the pivot member 20, so that the fitting member 26 may be easily detached from the pivot member 20, and thus, robust assembly may be realized.

On the other hand, the pin 30 is a hole formed in the hole 16 and the rotating member 20 of each of the protrusions 12 formed in the bracket 10 when the bracket 10 and the rotating member 20 is fastened ( It is inserted through the 22 to prevent the separation between the bracket 10 and the rotating member 20 and at the same time the rotating member 20 is rotatably supported around the pin (30).

Hereinafter, the assembly process of the door hinge made of the above configuration will be described with reference to FIGS. 1 and 2.

First, the fixing bracket 10 is fixed to the door frame, and then the rotating member 20 is fixed to the door.

Thereafter, after inserting the insertion portion 28 formed at the lower end of the fitting member 26 to the step 24 formed at the upper and lower ends of the rotation member 20, the space portion formed in the center of the fixing bracket 10 When the pivot member 20 is fastened to the head 14, the head portion 18 formed at the upper end of the fitting member 26 exposed to the upper and lower ends of the pivot member 20 may have the bracket 10 and the pivot member ( The gap (K) generated between the 20 to prevent the up and down flow of the rotating member (20).

Subsequently, when the pin 30 is fitted into the hole 16 of the protrusion 12 and the hole 22 of the pivot member 20 protruding from the upper and lower ends of the fixing bracket 10, the pin 30 is fixed. ) And the door and the door frame fastened to the fixed bracket 10 and the rotating member 20 by preventing the separation of the bracket 10 and the rotating member 20 while supporting the rotating member 20 so as to be rotatable. This will be rotated up and down freely.

As described above, the present invention prevents the rotational member from flowing upward and downward by blocking the clearance generated during the engagement of the bracket and the rotational member by using the fitting member fitted to the rotational member. There is an effect of preventing the flow of the door fixed to the member.

In addition, the present invention has an effect that the fitting member through the insertion portion that is fitted to the step of the rotating member can be implemented without deviating easily from the rotating member, solid assembly.
