Problems solved by technology

The existing hinges can only connect the door, window and door frame together and make them rotate relative to each other. This method cannot control the rotation speed of the door and window, and it is easy to cause phenomena such as slamming doors and windows, causing unnecessary losses. Shorten the life of doors and windows

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] As shown in the figure, a heaven-earth axis hinge with adjustable switching speed includes a casing 1, which is fixedly connected to the ground, and a fan-shaped cavity 2 is provided inside the casing 1, and the cavity 2 A fan-shaped slider 5 is provided, and the slider 5 is connected to the cavity 2 in rotation relative to the axis of the cavity 2. The radius and height of the slider 5 are the same as the radius and height of the cavity 2. The heights are all equal, the radian of the slider 5 is smaller than the radian of the cavity 2, the housing 1 is rotated and connected with a rotating shaft 3, and the axis of the rotating shaft 3 is the same as that of the cavity 2, so The lower end of the rotating shaft 3 extends into the cavity 2 and is fixedly connected with the slider 5. The top of the rotating shaft 3 is fixed with a door fixing device 4, an...

Abstract

The invention relates to a heaven-earth shaft hinge capable of adjusting switching speed. The heaven-earth shaft hinge capable of adjusting switching speed includes a shell, a cavity, a rotating shaft, a door fixing device, a sliding block, a ventilating pipe, an adjusting bolt, a handle, and a door. The shell is fixedly connected to the ground. The shell is internally provided with the fan-shapedcavity. The sliding block is located in a box. The lower end of the rotating shaft extends into the cavity and is fixedly connected with the sliding block. The top of the rotating shaft is connectedwith the fixing device. The door fixing device is fixedly connected to the door. The ventilating pipe is located in the shell. The two ends of the ventilating pipe correspondingly communicate with thetwo ends of the cavity. A threaded hole is vertically formed in the shell. The threaded hole is internally provided with the adjusting bolt in a screwed mode. According to the heaven-earth shaft hinge, the adjusting bolt is tightened or loosened, the ventilating speed of the ventilating pipe can be reduced or increased, so that the rotating speed of a door and a window is reduced or improved, inthis way, destructive phenomena such as door and window slamming are greatly reduced, unnecessary losses are reduced, and the service life of the doors and the window is prolonged.

Description

technical field [0001] The invention relates to the technical field of hinges, in particular to a sky-earth axis hinge whose switching speed can be adjusted. Background technique [0002] A hinge is a component that connects two parts of an object and enables it to move. It is often used in doors, windows, etc. The existing hinges can only connect the door, window and door frame together and make them rotate relative to each other. This method cannot control the rotation speed of the door and window, and it is easy to cause phenomena such as slamming doors and windows, causing unnecessary losses. The service life of doors and windows is shortened. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a hinge of a sky-earth axis with adjustable switching speed. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A heaven-earth axis hinge with adjus...
