An embodiment of the utility model provides a hinge device and refrigeration equipment with the same, the hinge device has a good lubricating effect, a door body is opened and closed more smoothly, and the hinge device is shown in fig. 1-3.

This hinge means 100 can install on equipment such as freezer 1000, refrigerator, vertical freezer, gradevin, dish washer, microwave oven, provides a freezer 1000 in this embodiment, as shown in fig. 4, including door body 200 and box 300, the inside refrigeration space that encloses of box 300, door body 200 seals the refrigeration space, is connected through hinge means 100 between door body 200 and the box 300, and hinge means 100 supports opening and closing of door body 200.

The hinge device 100 of the present embodiment includes a lower hinge housing 20, an upper hinge housing 10, and a rotation module by which the upper hinge housing 10 is rotatably connected to the lower hinge housing 20.

As shown in fig. 4, in order to clearly express the position and direction described in this embodiment, taking a horizontal refrigerator 1000 as an example, the opening of the refrigerator 1000 is defined to be upward, and the opposite direction is defined as downward, the door 200 is located above the refrigerator 300, the user is located on one side of the refrigerator 300 away from the hinge device 100 to operate the refrigerator 1000, the user is defined to be located in front of the refrigerator 1000, the hinge device 100 is located behind the refrigerator 300, and left and right are respectively defined from the front to two sides of the refrigerator 300.

The rotating module comprises a groove body 30 and a shaft body 40, wherein the groove body 30 comprises a groove cavity 301, a groove wall 302 enclosing the groove cavity 301, a lubricating hole 303 arranged on the groove wall 302, and a storage groove 304, the storage groove 304 is communicated with the groove cavity 301 through the lubricating hole 303, the shaft body 40 is connected in the groove body 30 in a sliding mode, and the storage groove 304 is used for containing a lubricating piece. When the shaft body 40 moves in the groove body 30, the shaft body is in contact with a lubricating piece arranged on the groove body 30, so that the friction between the shaft body 40 and the groove wall 302 is reduced, and the purpose of protecting the shaft body 40 and the groove body 30 is achieved.

Various embodiments exist for the form of the lubricant:

in one embodiment, the lubricating member is provided as solid grease, and the solid grease in the form of a paste is filled in the storage tank 304,

in addition, although the solid grease is filled to reduce the friction in long-term use, it is impossible to reduce the friction to zero, and the solid grease between the shaft body 40 and the groove wall 302 is reduced in long-term reciprocating motion, and the friction between the shaft body 40 and the groove body 30 tends to increase, so in this embodiment, the cross section of the storage groove 304 is gradually increased in a direction away from the lubrication hole 303, as shown in fig. 3. Lubrication in the movement of the shaft body 40 can be increased in real time.

Specifically, when the friction increases and wear occurs, the cross section of the storage groove 304 becomes smaller as it approaches the groove wall 302, so that the storage groove is more easily worn, the area of the lubrication hole 303 is increased, and more solid grease is exposed to be attached to the shaft body 40, so that lubrication is once again performed to reduce the friction.

By such circulation, when new abrasion is generated due to increase of friction, new solid grease can be attached to the surface of the shaft body 40 in time, and the effect of constant lubrication can be achieved.

In another embodiment, the lubrication member is provided as a ball that can roll in the storage groove 304, and the rolling area exposed through the lubrication hole 303 is in rolling contact with the shaft body 40, and when the shaft body 40 moves in the groove 30, the rolling occurs when the ball is in contact therewith, thereby reducing friction.
