In order to achieve the above object, the embodiment of the present application discloses a hinge structure for a track traffic air conditioning unit, including:

the movable sheet comprises a first plate and a second plate, the first plate is perpendicular to the second plate, the first plate is fixed on the condensing fan, and a first through hole is formed in the second plate and penetrates through the thickness of the second plate;

the fixing plate comprises a third plate and a fourth plate, the third plate is perpendicular to the fourth plate, a second through hole is formed in the third plate, and the fourth plate is fixed on the unit;

the first through hole of the second plate and the second through hole of the third plate are correspondingly arranged;

the hinge structure further comprises a rotating shaft, the rotating shaft penetrates through the first through hole and the second through hole in sequence, a limiting portion is arranged at one end of the rotating shaft, a third through hole is formed in the other end of the rotating shaft, the third through hole is arranged in a penetrating mode in the diameter direction of the rotating shaft, and a split pin is arranged in the third through hole.

Preferably, the first plate may be fixed to the condensing fan by a rivet or a screw.

Preferably, the fourth plate member is fixable to the unit by rivets or screws.

Preferably, a clearance of 1-5mm exists between the first through hole and the rotating shaft.

Preferably, the thickness of the first plate, the second plate, the third plate and the fourth plate ranges from 2 mm to 5mm.

The utility model has the advantages as follows:

In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or to implicitly indicate a number of the indicated technical features. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature.

To achieve the above object, please refer to fig. 1 and 2, the present invention provides a hinge structure for a track traffic air conditioning unit, including:

the hinge structure further comprises a rotating shaft, the rotating shaft sequentially penetrates through the first through hole and the second through hole, a limiting portion is arranged at one end of the rotating shaft, a third through hole is formed in the other end of the rotating shaft, the third through hole is arranged in a penetrating mode in the diameter direction of the rotating shaft, and a split pin is arranged in the third through hole.

Further, referring to fig. 1 and 2, the first plate may be fixed to the condensing fan by a rivet or a screw.

In this embodiment, referring to fig. 1, the fourth plate can be fixed on the unit by rivets or screws.

In this embodiment, referring to fig. 1, a gap of 1-5mm exists between the first through hole and the rotating shaft.

In the present embodiment, referring to fig. 1, the thickness ranges of the first plate, the second plate, the third plate, and the fourth plate are 2-5mm.

It can be understood that a gap of 1-5mm exists between the movable plate and the aperture of the rotating shaft, the axial adjustment distance of the movable plate is 1-5mm, and the fan has a certain adjustment room during assembly, so that the first through hole and the second through hole can be aligned better, and quick installation is facilitated. The hinge, the cotter pin and the gasket are made of stainless steel.

The movable plate and the fixed plate are connected through the rotating shaft, the gasket and the split pin to realize rotation. After the fan locking, movable plate and stationary blade are in contactless state, and the load that the fan received can not transmit to the frame through the hinge on to the hinge does not receive the load influence, the risk of inefficacy.
