Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a central armrest box flip hinge. Background Art

[0002] Hinge refers to hinge, which is used to connect two mechanical devices and can achieve movement, folding, etc. It is generally installed on doors and windows, wardrobe doors, and cabinet doors. Hinge plays an important role on the central armrest box.

[0003] The utility model patent application document with the publication number "CN218438856U" discloses a vehicle flip hinge, which is mainly composed of a hinge seat, a hinge block, a buffer device, a flip device and a blocking device. The technical solution uses the buffer device to gradually rotate and extrude the extrusion block inside the rotating sleeve toward the obstruction block with increasing thickness, so that the resistance brought by the rotation and extrusion of the hinge block gradually reduces the impact force of the hinge block rotation on the hinge seat, thereby achieving a buffering effect.

[0004] The automobile flip hinge disclosed in the above document has the following defects: during use of the automobile flip hinge, the buffer device and the blocking device of the hinge seat and the hinge block only work when they are in the closed state. However, when the hinge seat and the hinge block are opened, the flip structure cannot support the hinge seat and the hinge block well, which may cause the hinge seat and the hinge block to close.

[0005] It can be seen from this that the existing flip hinge does not have a good flip structure, and it is necessary to improve the existing deficiencies and provide a central armrest box flip hinge. Utility Model Content

A second mounting block is provided at one end of the second connecting plate away from the second column, and a second mounting hole is opened in the middle of the second mounting block. The internal thread of the second mounting hole is connected with a second bolt, and the second mounting block is movably mounted on the base through the second bolt.

[0011] Furthermore, connecting rods are provided at both ends of the second column, a groove is provided on the side of the first column close to the second column, and a threaded section is provided on the side of the first column away from the second column. The connecting rod is rotatably connected inside the groove, and the outer surface of the threaded section is threadedly connected to a limiting block.

[0012] Furthermore, the outer surfaces of the limit block and the threaded section are both provided with through holes, and the through holes are fixed to four and evenly distributed.

[0013] Furthermore, one end of the spring is mounted on the lower surface of the pressing plate, the other end of the spring is mounted on the outer surface of the base, and the limiting rod is slidably connected to the inside of the through hole.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model pushes the pressing plate downward so that the pressing plate pushes the guide rod to move downward. At the same time, the spring is compressed so that the limit rod is disengaged from the inside of the through hole. The cover plate is then pushed to open the cover plate. After opening, the pressing plate is released so that the spring recovers its elasticity and pushes the pressing plate upward so that the limit rod returns to the inside of the through hole. The first column supports the opened cover plate through the first connecting plate and the first mounting block, thereby achieving a better flipping effect.
