[0003] The above and prior art have the following defects: in the process of hinge working, the metal sheet drives the pivot to rotate frequently, because the friction between the metal sheet and the pivot is large, so the wear between the hinge and the pivot is serious, thereby the service life of the hinge is short.

[0004] Therefore, a wear -resisting container hinge is provided. UTILITY MODEL CONTENTS

[0005] The utility model discloses a kind of wear -resisting container hinges to solve the wear between the hinge and the pivot is serious due to the friction between the metal sheet and the pivot is large.

[0006] To achieve the above object, the utility model adopts the following technical scheme: a wear -resisting container hinge, including connecting plate, the connecting plate is rotatably connected with pivot, the circular arc surface of the pivot is fixedly connected with extension plate, the surface of the connecting plate is equipped with drip structure, the drip structure includes oil storage bottle, the oil storage bottle is fixedly connected with connecting plate, the lower end of the oil storage bottle is fixedly connected with clamping plate, the surface of the clamping plate is slidably connected with thimble, the circular arc surface of the thimble is fixedly connected with piston, the size of the piston is compatible with the size of dropper, the upper end of the pivot is fixedly connected with boss.

[0007] The effect reached by the above components is that by setting drip structure, when the door of container is opened, piston and dropper can be separated from contact, so that lubricating oil automatically flows into the gap between connecting plate and pivot, thereby lubricating connecting plate and pivot, reducing the friction between connecting plate and pivot, and further prolonging the service life of hinge.

[0008] Preferably, the boss is in conical structure.

[0009] The effect reached by the above components is that the boss in conical structure can extrude thimble, so that thimble automatically moves upward.

[0010] Preferably, the surface of the piston is fixedly connected with leaf spring, one end of the leaf spring is fixedly connected with dropper.

[0011] The effect achieved by the above components is that when the leaf spring is stretched, the piston slides downward by the elastic force of the leaf spring.

[0012] Preferably, the upper end of the thimble is fixedly connected with an elastic block, the inner wall of the dropper is fixedly connected with a hole plate, and the size of the elastic block is matched with the size of the hole plate.

[0013] The effect achieved by the above components is that when the thimble contacts the convex block, the thimble drives the elastic block to move upward to block the hole plate, thereby preventing the lubricating oil in the oil storage bottle from continuously flowing into the dropper and then flowing out to cause waste when the connecting plate stops rotating and the thimble contacts the convex block.

[0014] Preferably, the upper end of the oil storage bottle is clampingly connected with a bottle cap, the arc surface of the bottle cap is fixedly connected with a traction rope, and the traction rope is fixedly connected with the oil storage bottle.

[0015] The effect achieved by the above components is that when it is necessary to add lubricating oil, the bottle cap is removed and the oil storage bottle is filled with lubricating oil, and at this time, the traction rope can prevent the bottle cap from being lost.

[0016] Preferably, the upper end of the rotating shaft is fixedly connected with a blocking ring.

[0017] The effect achieved by the above components is that the blocking ring can limit the flow range of the lubricating oil, thereby preventing the lubricating oil from dropping to the ground to cause waste.

[0018] Compared with the prior art, the advantages and positive effects of the utility model lie in that,

[0019] In the utility model, when the door of the container is opened, the piston is separated from the dropper, the lubricating oil automatically flows into the gap between the connecting plate and the rotating shaft, the connecting plate and the rotating shaft are lubricated, the friction between the connecting plate and the rotating shaft is reduced, and the service life of the hinge is prolonged.
