Description

Technical Field

[0001] The invention relates to the technical field of door body rotary hinges, in particular to a refrigerator hinge with a support rod performing single-degree-of-freedom motion. Background Art

[0002] With the growth of economic level, people's living standards are getting higher and higher, and the requirements for various performance of freezers are getting higher and higher. Higher requirements are also put forward for the opening and closing degree of freezer doors and whether they can maintain stability. At the same time, higher requirements are also put forward for the size of hinges and the appearance of appearance.

[0003] Usually, the support rod of the freezer hinge can move up and down, and swing around a specific axis at the same time; the hinge of this support rod structure must have space to accommodate the swing range of the support rod, which leads to a larger hinge thickness; because the hinge is installed on the rear side of the freezer cabinet and protrudes from the freezer cabinet, the large thickness of the hinge has the following disadvantages: 1. Poor appearance; 2. Large space is occupied, the hinge protrudes too high from the outer surface of the freezer, and it takes up a certain amount of space whether it is placed, stored or transported, which increases logistics costs. Summary of the invention

[0004] The object of the present invention is to provide a refrigerator hinge with a support rod that performs single-degree-of-freedom motion, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a refrigerator hinge with a support rod that performs single-degree-of-freedom motion, comprising an upper body, a connecting plate, a rotating shaft, a bearing, a limiting hole, a supporting shaft, a lower body, a limiting protrusion, a support rod, a spring, a plastic guide seat, a supporting seat and a supporting tongue, wherein the inner walls on both sides of the top of the lower body are rotatably connected to the upper body through a rotating shaft, the outer walls on both sides of the bottom of the upper body are connected to connecting plates with rotating shafts, the inner walls between the connecting plates are provided with bearings, and limiting holes are provided through the outer walls of the lower body located on both sides of the connecting plates, and the bottom walls on both sides of the connecting plates are provided with A support shaft is sleeved and installed in the corresponding limiting hole on the end outer wall, and limiting protrusions are symmetrically arranged on the outer wall of the upper body on one side of the lower body. Support rods are distributed and inserted on the outer wall of the bottom end of the bearing shell, and a spring is sleeved on the outer wall of the bottom end of the support rod. Support tongues are symmetrically arranged on the inner walls on both sides of the bottom end of the lower body. A support seat is clamped and fixed on the inner wall of the lower body located between the support tongues, and a plastic guide seat is fixedly connected to the top outer wall of the support seat. The bottom end of the support rod is inserted and slid inside the plastic guide seat (11), and the bottom end of the spring contacts the top outer wall of the plastic guide seat.

[0006] As a further technical solution of the present invention: the support shaft passes through the limiting holes on both sides of the lower body, and the limiting holes are vertical. When the upper body rotates, the support shaft moves vertically up and down along the limiting holes on both sides of the lower body under the push of the support rod through the bearing, thereby ensuring that the support rod only makes single-degree-of-freedom movement in the vertical direction.

[0007] Furthermore, mounting holes are provided through the outer walls of one side of the upper body and the lower body.

[0008] Compared with the prior art, the beneficial effects achieved by the present invention are: the invention has a relatively simple and compact structure, can provide the same ability to support the door body as the traditional hinge, reduce the thickness of the hinge, thereby minimizing the size of the cabinet body protruding from the cabinet body surface on the rear side, making the overall hinge beautiful, occupying a small space, and facilitating later storage and transportation.
