Compared with the prior art, the utility model has the advantages that the rotating center between the fixed block and the rotating block is moved downwards to the bottom end of the fixed block, so that the rightmost end of the rotating block can not interfere with the fixed support all the time when the rotating block rotates around the rotating center.

Description

Hinge mechanism

Technical Field

The utility model relates to the technical field of rotating mechanisms, in particular to a hinge mechanism.

Background

Hinges, also known as hinges, are mechanical devices used to connect two solids and allow relative rotation between them. The hinge may be constructed of a movable component or may be constructed of a foldable material.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in fig. 2, a hinge mechanism of the present invention includes: positioning seat 10, fixed block 11, and slewing mechanism 12.

The fixed block 11 is detachably arranged on the positioning seat 10, a connecting part 13 is arranged on the fixed block 11, and the connecting part 13 extends downwards to form a hinge part 14; one end of the rotating mechanism 12 is hinged on the hinge part 14. Compared with the prior art, the lower rotation center of the rotating mechanism 12 allows the rightmost end of the rotating mechanism 12 to move less in the vertical direction when the rotating mechanism 12 rotates around the axis position of the hinge portion 14, so that a mold equipped with the hinge structure of the utility model can be used for installing other parts of the mold.

The rotating mechanism 12 includes: a rotating shaft 15 and a rotating block 16.

The rotation shafts 15 are provided on the hinge portion 13 along both sides in the longitudinal direction; the rotating block 16 extends downward to form a rotating portion 17, and the rotating portion 17 is rotatably provided on the rotating shaft 15.

The rotating block 16 further comprises a rotating piece 18, one end of the rotating piece 18 is detachably arranged on the rotating block 16, and the lower part of the rotating piece 18 is movably abutted with the positioning seat 10.

The hinge mechanism of the utility model also comprises a fixed bracket 19, and one end of the fixed bracket 19 is movably abutted with one end of the rotating piece 18 far away from the rotating block 16.

As shown in fig. 3, a rotation groove 20 is formed in the middle of the hinge portion 14, the rotation portion 17 is rotatably disposed in the rotation groove 20, and the rotation groove 20 is formed to allow the first rotation member 18 to rotate more smoothly with respect to the fixed block 11.

In a preferred embodiment of the present invention, the rotating portion 17 has a hollow cylindrical shape, and the hollow cylindrical rotating portion 17 can facilitate the installation of the rotating block 16 and the rotating shaft 15.

It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.
