Description
Technical field
The utility model is related to hinge technical field more particularly to a kind of axis hinges of adjustable switch speed.
Background technology
Hinge is two parts of attached article and can be allowed to movable component, is usually used in door, window etc..Existing hinge is only capable of
Door, window are connected together with doorframe and are allowed to relatively rotate, this mode is unable to control the velocity of rotation of door, window, is easy to make
At falling door, falling phenomena such as window, unnecessary loss is caused, shortens door, window only uses the service life.
Invention content
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of axis conjunction of adjustable switch speed
Page.
The utility model to achieve the above object, using following technical scheme：
A kind of axis hinge of adjustable switch speed, including shell, the shell is fixedly connected on the ground, described
Be equipped with fan-shaped cavity in shell, be equipped with fan-shaped sliding block in the cavity, the sliding block relative to the cavity axle center with
The cavity is rotatedly connected, and the radius and height and the radius and height of the cavity of the sliding block are equal, the sliding block
Radian is less than the radian of the cavity, and shaft, the axle center in the axle center of the shaft and the cavity are rotatably connected on the shell
Identical, the lower end of the shaft is stretched into the cavity and is fixedly linked with the sliding block, and door is installed at the top of the shaft
Fixing device, the door fastening device are fixedly connected on door, and snorkel, the both ends point of the snorkel are equipped in the shell
It is not connected to the both ends of the cavity, is equipped with threaded hole on the shell vertically, the internal diameter of the threaded hole is logical not less than described
The diameter of tracheae and run through the snorkel, is rotary with adjusting bolt in the threaded hole.
It is installed with handle at the top of the adjusting bolt.
The door fastening device is fixedly connected on by screw and nut mechanism on the door.
The utility model has the beneficial effects that：The adjusting bolt of the utility model is screwed or unscrewed, can be decreased or increased
The draft speed of snorkel, to reduce or improve the velocity of rotation of door, window, this method, which greatly reduces, falls door, falls window etc.
Destructive phenomenon reduces unnecessary loss, extends the service life of door, window.

It is described in detail with reference to attached drawing below with reference to the embodiments of the present invention.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown, a kind of axis hinge of adjustable switch speed, including shell 1, the shell 1 are fixedly connected on
On ground, fan-shaped cavity 2 is equipped in the shell 1, is equipped with fan-shaped sliding block 5 in the cavity 2, the sliding block 5 relative to
The axle center of the cavity 2 is rotatedly connected with the cavity 2, the radius and height of the radius and height and the cavity 2 of the sliding block 5
Degree is equal, and the radian of the sliding block 5 is less than the radian of the cavity 2, and shaft 3, the shaft are rotatably connected on the shell 1
3 axle center is identical as the axle center of the cavity 2, and the lower end of the shaft 3 is stretched into the cavity 2 and fixed with the sliding block 5
It is connected, the top of the shaft 3 is installed with door fastening device 4, and the door fastening device 4 is fixedly connected on door 9, the shell
Snorkel 6 is equipped in 1, the both ends of the snorkel 6 are connected to the both ends of the cavity 2, are equipped with vertically on the shell 1 respectively
The internal diameter of threaded hole, the threaded hole is not less than the diameter of the snorkel 6 and runs through the snorkel 6, in the threaded hole
It is rotary with adjusting bolt 7.
7 top of the adjusting bolt is installed with handle 8.
The door fastening device 4 is fixedly connected on by screw and nut mechanism on the door 9.
When the utility model is used, when door 9 is rotated to side, sliding block 5 is rotated with shaft 3 to side, the cavity 2 of the side
Volume reduce the volume of the cavity 2 of offside simultaneously and increase, the gas in the cavity 2 of the side passes through snorkel 6 and flows into offside
In cavity 2, since the section of snorkel 6 is limited, the limited speed of gas flowing makes the speed that sliding block 5 rotates obtain centainly
Control, to control the velocity of rotation of door 9 by shaft 3, door fastening device 4.
When needing to improve the velocity of rotation of door 9, adjusting bolt 7 is unscrewed, section of the snorkel 6 at adjusting bolt 7 is made
Product increases, and the flowing velocity of gas is accelerated, to improve the velocity of rotation of door 9；When the velocity of rotation for needing reduction door 9
When, adjusting bolt 7 is screwed, so that sectional area of the snorkel 6 at adjusting bolt 7 is reduced, reduces the flowing velocity of gas, to
Reduce the velocity of rotation of door 9.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the various improvement of the methodology and technical solution progress of the utility model are used, or without
Improvement directly applies to other occasions, both is within the protection scope of the present invention.
