Abstract
The utility model discloses a rotating shaft structure, be fixed in including the cabin body and a rotation the hatch door of the cabin body, the cabin body is including a main part, an upward pivot and a pivot once, it reaches pivot follow down to go up the pivot the main part is extended, the hatch door includes that one leads to the axle, lead to the axle with go up the pivot with the infraduction shaft fit makes the hatch door rotate install in the cabin body. The utility model discloses rotating shaft structure's last pivot reaches pivot down and follows the main part is extended, and the integrated design need not the installation, can not produce installation error, can guarantee also during production that last pivot and lower pivot axle center are at same straight line to the perpendicular to horizontal plane, the hatch door through lead to the axle rotate install in go up pivot and pivot down, can prevent that the hatch door is flagging.
Description
Technical field
The utility model is related to a kind of pivot structure, more particularly to a kind of pivot structure for preventing hatch door sagging.
Background technology
In prior art and daily life, rotating shaft door is very common.Upper lower rotary shaft of the prior art is removable
It is fixed in nacelle with unloading.Due to processing and alignment error, it is easy to cause the axle center of lower rotary shaft not in same straight line or
Without vertical, cause hatch door sagging.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of to be prevented from hatch door sagging
Pivot structure.
The purpose of this utility model employs the following technical solutions realization：
A kind of pivot structure, including a nacelle and one rotate and be fixed on the hatch door of the nacelle, the nacelle includes that one leads
Body, rotating shaft and a lower rotary shaft on one, the upper rotating shaft and lower rotary shaft extend from the main body, and the hatch door is logical including one
Axle, the axis coordinates with the upper rotating shaft and the lower rotary shaft makes the hatch door rotation be installed on the nacelle.
Preferably, the axis is respectively arranged at two ends with a fluting, and the upper rotating shaft and lower rotary shaft are plugged in two fluting
Among.
Preferably, the pivot structure also includes two sleeves, and sleeve described in is sheathed on the upper rotating shaft and is contained in institute
Fluting is stated, to avoid the upper rotating shaft with the axis friction.
Preferably, another sleeve is sheathed on the lower rotary shaft and is contained in the fluting, to avoid the lower rotary shaft
With the axis friction.
Preferably, the pivot structure also includes two cushions, and cushion described in is located at the upper rotating shaft and the set
Between cylinder, another cushion is located between the lower rotary shaft and the sleeve.
Preferably, the nacelle is additionally provided with a mounting groove, and the axis is contained in the mounting groove.
Compared to existing technology, the beneficial effects of the utility model are：
The upper rotating shaft of the utility model pivot structure and lower rotary shaft extend from the main body, integrated design, without the need for
Install, alignment error will not be produced, rotating shaft and lower rotary shaft axle center are also ensured that during production in same straight line, and perpendicular to water
Plane, hatch door is rotated by axis and is installed on the upper rotating shaft and lower rotary shaft, is prevented from hatch door sagging.

Specific embodiment
Fig. 1 to Fig. 3 is referred to, a kind of pivot structure 100 includes a nacelle 10, a hatch door 20, two cushions 30 and two sets
Cylinder 40.
The nacelle 10 includes the lower rotary shaft 14 of rotating shaft 12 and in a main body 11,.The upper rotating shaft 12 and described lower turn
Axle 14 extends from the main body 11.The upper rotating shaft 12 and the lower rotary shaft 14 are located at same straight line.The nacelle 10 is also
A mounting groove 16 is provided with, the mounting groove 16 is located on the line of the upper rotating shaft 12 and the lower rotary shaft 14.
The hatch door 20 includes an axis 22, and the axis 22 is respectively arranged at two ends with a fluting 220.
When assembling the pivot structure 100, two cushion 30 and two sleeve 40 are sheathed on respectively described upper turn
On axle 12 and the lower rotary shaft 14, the axis 22 is contained in the mounting groove 16 and the two ends of the axis 22 above turn with described
Axle 12 and the grafting of the lower rotary shaft 14.The upper rotating shaft 12 and the lower rotary shaft 14 are contained in the fluting 220, make the hatch door
The nacelle 10 is fixed in 20 rotations.
Now sleeve 40 described in is located between the upper rotating shaft 12 and the axis 22, and another sleeve 40 is located at institute
State between lower rotary shaft 14 and the axis 22, to prevent the upper rotating shaft 12 and the lower rotary shaft 14 from producing with the friction of the axis 22
Raw noise, reduces service life.Cushion 30 described in one is located between the upper rotating shaft 12 and the sleeve 40, another described to state
Cushion 30 is located between the lower rotary shaft 14 and the sleeve 40, when the pivot structure 100 is impacted, the elasticity
Pad 30 deforms, and hatch door 20 is slightly moved, and will not be impacted.
The upper rotating shaft 12 of the pivot structure 100 and lower rotary shaft 14 extend from the main body 11, integrated design, nothing
Need to install, alignment error will not be produced, also ensure that the upper rotating shaft 12 and the axle center of the lower rotary shaft 14 with always during production
Line, and perpendicular to horizontal plane, the hatch door 20 is rotated by the axis 22 and is installed on the upper rotating shaft 12 and described lower turn
Axle 14, is prevented from the hatch door 20 sagging.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim
Within the scope of.
