Description

Technical field:

[0001] The invention relates to a refrigerator hinge with a self-lubricating device and a refrigerator, belonging to the technical field of refrigerators. Background technology:

[0002] Hinges are typically located at the junction of the refrigerator body and door, and support is provided by the spring compression within the hinge. When the door is opened beyond a certain angle, such as between 35° and 75°, the spring force generated by the spring can easily accelerate the door's rotation, causing it to suddenly stop at the stopping point, generating a large impact force that can damage the door, cabinet, and hinges, reducing their service life.

[0003] Existing hinges are usually lubricated by applying Vaseline at the beginning of assembly. However, after a large number of door openings and closings, wear will still occur, causing damage and failure at the hinge shaft. Moreover, after the hinge is assembled, it is difficult to apply Vaseline later.

[0004] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Summary of the invention:

[0005] The present invention aims to solve the problems existing in the above-mentioned prior art and provides a refrigerator hinge and a refrigerator with a self-lubricating device, which can realize full life cycle lubrication of the hinge shaft during the process of opening and closing the refrigerator door, thereby extending the life cycle of the refrigerator door hinge and the refrigerator.

A metal plate is installed on the lower surface of the hinge stop oil storage shaft groove, and the upper end of the spring clip is installed together with the metal plate. The spring is sleeved on the outside of the spring clip and can drive the spring clip to move through its elastic force.

[0007] Furthermore, the hinge shaft is inserted from the hinge shaft mounting hole on one side wall of the hinge lower page, passes through the hinge shaft oil storage shaft groove, and is fixed to the hinge shaft mounting hole position on the other side wall of the hinge lower page.

[0008] Furthermore, the hinge upper page can rotate around the hinge axis.

[0009] Furthermore, the hinge stop is inserted from the hinge stop travel groove on one side wall of the lower hinge page, passes through the hinge stop oil storage shaft groove, and is located in the hinge stop travel groove on the other side wall.

[0010] Furthermore, the hinge stop and the hinge upper page are fixed together.

[0011] Furthermore, a snap hole is formed in the middle of the metal plate, and a snap portion is formed on the upper end protrusion of the spring clip to be snapped into the snap hole.

[0012] Furthermore, a stop portion is formed on the outer side wall of the spring clip and below the buckle portion.

[0013] Furthermore, a metal base is fixed to the lower end of the lower leaf of the hinge, a rubber pad is installed at the center of the metal base, the upper end of the spring abuts against the stopper, and the lower end abuts against the rubber pad.

[0014] Furthermore, the lower end of the spring clip passes through the spring, the rubber pad and the metal base and extends to the bottom of the metal base.

[0015] The present invention also adopts the following technical solution: a refrigerator, comprising a cabinet, a door, and a refrigerator hinge with a self-lubricating device, wherein the upper page of the hinge is fixed to the door, and the lower page of the hinge is fixed to the cabinet.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] The refrigerator hinge with a self-lubricating device of the present invention includes a hinge upper page 1, a hinge shaft 2, a hinge stop 3, a spring card 4, a spring 5 and a hinge lower page 6, and a hinge shaft oil storage shaft groove 10 and a hinge stop oil storage shaft groove 12 are respectively protruded on the inner surfaces of the opposite side walls of the hinge upper page 1, wherein an oil pipe channel 11 is integrally formed between the hinge shaft oil storage shaft groove 10 and the hinge stop oil storage shaft groove 12 formed on the same side wall of the hinge upper page 1 to connect the internal spaces of the hinge shaft oil storage shaft groove 10 and the hinge stop oil storage shaft groove 12, and an oil filling hole 110 is formed on the side wall of the oil pipe channel 11.

[0025] On the two opposite side walls of the hinge lower page 6 at the ends thereof, a hinge shaft mounting hole 60 and a hinge stopper stroke groove 61 are formed at positions opposite to the hinge shaft oil storage shaft groove 10 and the hinge stopper oil storage shaft groove 12, respectively. The hinge shaft 2 is inserted from the hinge shaft mounting hole 60 on one side wall of the hinge lower page 6, passes through the hinge shaft oil storage shaft groove 10, and is then fixed to the hinge shaft mounting hole 60 on the other side wall of the hinge lower page 6. The hinge upper page 1 can rotate around the hinge shaft 2. The hinge stop 3 is inserted from the hinge stopper stroke groove 61 on one side wall of the hinge lower page 6, passes through the hinge stopper oil storage shaft groove 12, and is then located in the hinge stopper stroke groove 61 on the other side wall. The two ends of the hinge stop 3 can slide in the hinge stopper stroke grooves 61 on the opposite side walls of the hinge lower page 6. The hinge stop 3 and the hinge upper page 1 are fixed together.

[0026] A metal plate 7 is mounted on the lower surface of the hinge stop oil reservoir groove 12. A snap hole (not shown) is formed in the center of the metal plate 7. A snap portion 40 is formed on the upper end of the spring clip 4, which snaps into the snap hole. A stopper 41 is formed on the outer wall of the spring clip 4, below the snap portion 40.

[0027] The lower end of the hinge lower leaf 6 is fixed to a metal base 8, with a rubber pad 9 installed in the center of the metal base 8. The upper end of the spring 5 abuts against the stopper 41, and the lower end abuts against the rubber pad 9. The lower end of the spring clip 4 passes through the spring 5, the rubber pad 9, and the metal base 8 and extends to the bottom of the metal base 8.

[0028] The working principle of the refrigerator hinge with self-lubricating device of the present invention is as follows: the lubricating oil is stored in the hinge stop oil storage shaft groove 12 through the oil filling hole 110, and the door is closed. Figure 1 As shown, the lubricating oil surface contacts the hinge stopper 3. Since the hinge stopper oil storage shaft groove 12 is closely matched with the hinge stopper 3, the lubricating oil will not leak out, and the hinge stopper 3 can be lubricated at the same time. Figure 2 As shown, the lubricating oil flows into the hinge shaft oil storage shaft groove 10 through the oil pipe channel 11 connecting the hinge stop oil storage shaft groove 12 and the hinge shaft oil storage shaft groove 10. At the same time, when the refrigerator door is opened, the hinge stop 3 moves along the hinge stop travel groove 61, thereby driving the metal plate 7 to move. The spring clip 4 moves along with the metal plate 7 under the action of the spring 5.

[0029] The operating principle of the refrigerator door hinge relies on the action of the spring 5 to apply a certain damping force. During the opening process of the door body, due to inertia, it will slightly rush in the opening direction, so that a sufficient amount of lubricating oil flows into the hinge shaft oil storage shaft groove 10 to further lubricate the hinge shaft. When the door body is closed, the hinge shaft oil storage shaft groove 10 is lifted to the position of the hinge stop oil storage shaft groove 12. At this time, due to its own gravity, the lubricating oil flows into the hinge stop oil storage shaft groove 12 through the oil pipe channel 11 connecting the hinge stop oil storage shaft groove 12 and the hinge shaft oil storage shaft groove 10, so as to be stored until the next time the door is opened.

[0030] The refrigerator hinge with its own lubrication device can continuously provide lubrication for the door hinge throughout the entire life cycle of the refrigerator. After a large number of door openings and closings, there is a certain risk of loss of lubricating oil. An oil filling hole is reserved for adding lubricating oil to achieve a continuous effect.

[0031] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
