Description
Technical field
The utility model belongs to building materials hardware, and in particular to a kind of built-in accumulator door hinge.
Background technology
At present, it is each to be widely used in antitheft door, fire resistant doorsets, machine tool etc. as a kind of common components for door hinge
In kind equipment, but current door hinge does not have accumulator, and lubricating oil can only be added to the rotatable parts of door hinge by way of smearing
On, if addition it is more, easily flow down, cause pollution on the door and the waste to lubricating oil, if addition compared with
It is few, do not have the effect of lubrication at all, the rotational structure of door hinge caused to be seriously worn, service life is relatively low, rotating effect compared with
Difference.
Occur the door hinge that a part has slide construction at present, but the carriage of door hinge is all an exposure to outside, this
Sample lubricating oil can volatilize quickly, and carriage can not be operating normally by original design, and the service life of accessory is still relatively low.
It would therefore be highly desirable to work out a kind of excellent built-in accumulator door hinge of lubricant effect with accumulator.
Utility model content
For solution more than technical problem, the utility model provides a kind of built-in accumulator door hinge, simple in structure, and lubricates
Oil is not volatile, extends the service life of accessory, reduces maintenance times, reduces working strength, has higher practical value.
To achieve the above object, the utility model provides following scheme：
Accumulator door hinge built in the utility model offer, including shaft, fixing axle and center pillar, the lower end of the center pillar and institute
The upper end for stating fixing axle is fixedly connected, accumulator built in the upper end of the center pillar, built-in steel ball in the accumulator, and the steel
The top peak of pearl is higher than the height of the center pillar, shaft lower end built-in bearing, and passes through the bearing holder (housing, cover) set on institute
It states on center pillar so that the shaft can surround the center pillar and rotate.
Optionally, the centre of sphere height of the steel ball is less than or equal to the height of the center pillar.
Optionally, the shaft is stainless rotating steel shaft, and the fixing axle is stainless steel fixing axle.
Optionally, the center pillar and the fixing axle are integrally formed setting.
Optionally, the oil storage chamber cross-section is circle.
Optionally, the center pillar is cylindrical structure.
The utility model achieves following technique effect relative to the prior art：
1st, built-in accumulator door hinge provided by the utility model, is provided with accumulator, lubricating oil is not volatile so that steel ball
Lubricating status is always maintained at, simple in structure, the service life of accessory is long, and maintenance times are few, and working strength is relatively low, has higher
Practical value.
2nd, the centre of sphere height of the steel ball of built-in accumulator door hinge provided by the utility model is less than or equal to the height of center pillar,
The setting of this height so that steel ball is similar to embedded structure, relative to the structure that traditional steel ball protrudes, the utility model
Steel ball rotation can be consolidated in accumulator, the probability being displaced greatly reduces, have higher practical value.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
The purpose of this utility model is to provide a kind of built-in accumulator door hinge simple in structure, is provided with accumulator, profit
Lubricating oil is not volatile so that steel ball is always maintained at lubricating status, and the service life of accessory is long, and maintenance times are few, working strength compared with
It is low, there is higher practical value.
Above-mentioned purpose, feature and advantage to enable the utility model are more obvious understandable, below in conjunction with the accompanying drawings and have
Body embodiment is described in further detail the utility model.
Built-in accumulator door hinge provided by the utility model, as shown in Figs. 1-3, including shaft 1, fixing axle 2 and center pillar 3,
The lower end of center pillar 3 is fixedly connected with the upper end of fixing axle 2, accumulator 4 built in the upper end of center pillar 3, built-in steel ball 5 in accumulator 4,
And the top peak of steel ball 5 is higher than the height of center pillar, 1 lower end built-in bearing 6 of shaft, and passes through bearing 6 and be sheathed on center pillar 3
On so that shaft 1 can be rotated around center pillar 3.Traditional door hinge does not have accumulator, and lubricating oil can only be added by way of smearing
Onto the rotatable parts of door hinge, if addition is more, easily flows down, cause pollution on the door and the wave to lubricating oil
Take, it is readily volatilized if addition is less, it does not have the effect of lubrication at all, the rotational structure of door hinge is caused to be seriously worn,
Service life is relatively low, and rotating effect is poor.But built-in accumulator in the door hinge of the utility model, it is filling always in accumulator
There is lubricating oil, lubricating oil is not volatile so that steel ball is always maintained at lubricating status, is not susceptible to wear, the service life of accessory
It greatly prolongs.
Steel ball is displaced in order to prevent, the centre of sphere of steel ball 5 is highly set smaller than or the height equal to center pillar, this
The setting of height so that the structure setting of steel ball is similar to embedded structure, relative to the structure that traditional steel ball protrudes, this reality
Rotation can be consolidated in accumulator with novel steel ball, the probability being displaced greatly reduces, and has higher practical value.
In order to prevent because of the corrosion that abrasion causes in rotary course, shaft 1 is stainless rotating steel shaft, and fixing axle 2 is stainless steel
Fixing axle, this stainless steel cause shaft during being rotated around center pillar, effectively prevent the hair of corrosion
Life extends service life.
In order to realize the stabilization of rotation process, center pillar 3 and fixing axle 2 are integrally formed setting, when shaft is around center pillar hair
During raw rotation, it will not cause because of the shaking of center pillar and crack or damage are generated between center pillar and fixing axle.
Preferably, 4 cross section of accumulator is circle, and center pillar 3 is cylindrical structure.
It can be seen that built-in accumulator door hinge provided by the utility model, is provided with accumulator, lubricating oil is not easy to wave
Hair so that steel ball is always maintained at lubricating status, and the service life of accessory is long, and maintenance times are few, and working strength is relatively low, has higher
Practical value.
It should be noted that the shaft and fixing axle of the built-in accumulator door hinge of the utility model, which differ, is set to stainless steel
Matter, as long as there can be the material of certain anticorrosion and wearability.The company of 3 one end of center pillar and one end of fixing axle 2
It connects mode and is also not limited to an entirety, as long as being that by the mode being bonded of center pillar and fixing axle.
Specific case is applied in this specification to be expounded the principle and embodiment of the utility model, more than it is real
The explanation for applying example is merely used to help understand the method and its core concept of the utility model；Meanwhile for the general of this field
Technical staff, according to the thought of the utility model, in specific embodiments and applications there will be changes.To sum up institute
It states, the content of the present specification should not be construed as a limitation of the present invention.
