BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper hinge for heavy equipment, and more particularly, to a stopper hinge for heavy equipment that can simultaneously realize a hinge function for an opening and closing object and a stay function for maintaining an open state.

The present invention relates to a heavy-duty stopper hinge which can simplify the structure so as to improve ease of use and reduce manufacturing costs.

The present invention relates to a stopper hinge for a heavy equipment which is capable of maintaining a stay function even when an impact or vibration is applied from the outside, thereby improving safety.

 In general, a hinge is an accessory used for a door that opens and closes while rotating about a certain axis, also referred to as a hinge. Such a hinge is widely used not only in industrial sites such as heavy construction equipment but also in everyday life such as office and home.

The hinge used in the construction heavy equipment rotatably supports the iron door and functions to connect the door to the main body of the heavy equipment so that it can be opened and closed. However, a separate door stay device is needed to keep the door open.

Generally, gas springs are used to keep the door open. However, since the gas spring is installed separately from the hinge, it can not be applied to a place where the installation space is narrow, and the cost of the gas spring itself is high, And the stay function is lost due to gas leakage during long-term use, which is not preferable.

Accordingly, Korean Utility Model Registration Utility Model No. 20-0453772 discloses a heavy-duty door stay in which a door can be easily released and maintained as shown in FIG.

However, since the door stay is constructed separately from the hinge, there is a problem that a lot of installation space is required, and the manufacturing cost is high because it includes a large number of parts.

 Accordingly, in Korean Patent Laid-Open Nos. 10-20130051704 and 10-2014-0006517, as shown in Figs. 2 and 3, a stay unit is provided on one side of a hinge having a first plate and a second plate rotatable relative to each other A door hinge for heavy equipment is disclosed in which the door can be prevented from being closed by allowing the end portion to come into contact with the plate by selectively rotating the door hinge.

However, the related art has the following problems.

That is, since the stay unit is configured to rotate in the direction of gravity and to prevent the door from being closed by its end contacting with the plate, it is applicable to vertically erected doors but is not applicable to doors that are opened and closed in the upward / downward directions.

That is, in the case of the upward / downward retractable door, when a shock or vibration is applied from the outside because a load is not applied, the stay unit is rotatable, so that the restraint to the plate is canceled and the stay function can not be performed.

In order to solve such a problem, Korean Utility Model Registration No. 20-0476161 discloses, as shown in FIG. 4, a main body 20 having a support bracket 20 and a stay 30 at one side of a cover 10 rotated by the action of a hinge 12, An opening / closing device for a cost cover is disclosed.

However, in order to stably hold the open cover 10, the locking nut 34 must be rotated and moved in the longitudinal direction of the main shaft portion 31 before screwing.

Therefore, there is a problem that the usability is reduced and the time required for staying is delayed.

The detailed structure of the stay unit 140 will be described with reference to FIG.

FIG. 8 is an exploded perspective view of FIG. 6 showing the detailed configuration of the stopper hinge 100 according to the present invention.

The stay unit 140 is capable of controlling the rotatable state and the stay state of the stopper hinge 100 by increasing or decreasing the number of the interference target links 130 using the elastic restoring force, It is possible to perform a stay function by using the restoring force and further restraining another link 130 only at a certain angle when the movable bracket 120 rotates.

To this end, the stay unit 140 includes an elastic member 142 and a case 144 (not shown) which is coupled with the elastic member 142 in one of the fixed link 132 and the movable link 134 An operation part 146 which is partially inserted into the case 144 to penetrate the elastic member 142 and which can be grasped by a user to perform linear force movement; And an elasticity generating member 148 for generating an elastic restoring force on the elastic member 142.

The elastic member 142 is installed inside the case 144 so as to penetrate the pin-shaped operating portion 146. The elastic member 142 is pushed rightward by the elastic member 148 located on the left side The elastic restoring force is generated in the left direction.

Therefore, the elastic restoring force generated by the elastic member 142 pushes the operating portion 146 in the left direction, and can selectively pass through the fixed-side link 132 and the movable-side link 134.

In the embodiment of the present invention, the stay unit 140 is positioned inside the stopper hinge 100 to generate an elastic restoring force in the left direction, and the left end of the operation portion 146 is in contact with the inside As shown in FIG.

The movable link 134 includes a receiving portion 138 to selectively receive the end portion of the operating portion 146 to perform a stay function.

More specifically, the operating portion 146 maintains the state where the end portion is inserted into the through hole 136 at all times, and the receiving portion 138 and the normal through hole 136 are not located on the same straight line as the operating portion 146 The fixed link 132 and the movable link 134 are rotatable relative to each other and when the accommodating portion 138 and the normal through hole 136 are located on the same straight line as the operating portion 146, Is received in the receiving portion 138 to limit relative rotation.

This is because the elastic member 142 is in the state of generating the elastic restoring force in the left direction. In order to cancel the elastic restoring force, the operation unit 146 is pulled in the right direction, It is only necessary to deviate to the right direction.

The scope of the present invention is not limited to the above-described embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the scope of the present invention.

For example, in the embodiment of the present invention, the stay unit 140 is constituted by a single unit on the left side of the stopper hinge 100, but it may be disposed on the right side if necessary, Of course.

In the embodiment of the present invention, the normal through-hole 136 is formed in a rounded shape, but it is slip in contact with the end of the operating portion 146 to selectively receive the rotation of the movable link 134, It may be formed by perforating it so long as it can intervene.

Needless to say, the rotation angle (stalled angle) of the movable bracket 120 with respect to the stationary bracket 110 can be changed by changing the forming position of the normal through-hole 136.
