Abstract
The utility model essentially discloses a kind of sealing cover for automatic adjusument hinged closure structure, its technical solution: including circular cover body, it is mounting hole among circular cover body, circular cover body side is provided with location hole, the circular cover body upper surface is equipped with groove, is equipped with seal groove on the inside of mounting hole.It is mounting hole among circular cover body, is equipped with seal groove on the inside of mounting hole, for installing sealing ring, is interference fitted by sealing ring and pin shaft, so as to form closed hinged closure space.Circular cover body side is provided with location hole, and sealing cover can be installed by being connect by positioning pin with location hole.The utility model can reach good sealing effect, so that foreign matter dust be prevented to enter hinge, thereby reduces abrasion, reduces operation noise, extend service life.
Description
Technical field
The utility model relates to chain technical field, especially a kind of sealing for automatic adjusument hinged closure structure
Lid.
Background technique
Currently, for dust atmosphere chain be typically employed in harbour, coal mine, etc. occasions.The environment of these applications
Feature is that dust is more, has higher seal request, wear-resistant requirement and noise requirements to chain, being otherwise unable to satisfy client makes
Use life requirements.Wherein bucket continuous ship unloader is widely applied at harbour, and matching used conveyor chain is using biography mostly
The conveyor chain of structure of uniting and technological design manufacture, design feature are hinged closure structure.At home, hinged closure structure one
As be all use between interior outer plate increase sealing ring structural shape to reach sealing purpose, but the practical sealing of this mode
Effect is undesirable, and noise is big when use, and service life is short.At abroad, hinged closure structure is typically all to be equipped with using inner plate
Groove, outer plate are equipped with boss, by being intermeshed between the two and increasing the structural shape of copper backing on the outside to reach sealing
Purpose, but the practical sealing effect of this mode is also undesirable.
Utility model content
In view of the deficienciess of the prior art, the utility model provide it is a kind of for automatic adjusument hinged closure structure
Sealing cover can reach good sealing effect, so that foreign matter dust be prevented to enter hinge, thereby reduces abrasion, reduces
Noise is run, service life is extended.
In order to achieve the above object, the utility model is achieved through the following technical solutions: one kind being used for automatic adjusument
The sealing cover of hinged closure structure, including circular cover body, circular cover body centre are mounting hole, the setting of circular cover body side
There is location hole, the circular cover body upper surface is equipped with groove, is equipped with seal groove on the inside of mounting hole.
The utility model is further, be equipped with sealing ring in the seal groove.It is interference fitted by sealing ring and pin shaft,
So as to form closed hinged closure space.
For the utility model further, circular cover body lower surface is equipped with lug boss, permission wear height prevents abrasion entire
Face.
The utility model is further, lug boss height raised on circular cover body lower surface is 0.2mm-2mm.
The utility model is further, lug boss height raised on circular cover body lower surface is 0.5mm.
The utility model has the beneficial effect that
It is mounting hole among circular cover body, is equipped with seal groove on the inside of mounting hole and passes through sealing for installing sealing ring
Circle is interference fitted with pin shaft, so as to form closed hinged closure space.
Circular cover body side is provided with location hole, and sealing cover can be pacified by being connect by positioning pin with location hole
Dress.
The circular cover body upper surface is equipped with groove, is used for shock mount in groove, plays the work of sealing cap capable of regulating position
With.Circular cover body lower surface is equipped with lug boss, allows wear height, prevents abrasion entire surface.The utility model can reach good
Good sealing effect thereby reduces abrasion so that foreign matter dust be prevented to enter hinge, reduces operation noise, extends
Service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model planar structure schematic diagram；
Fig. 3 is utility model works structural schematic diagram.
Appended drawing reference: 1, circular cover body；2, mounting hole；3, location hole；4, groove；5, seal groove；6, lug boss.
Specific embodiment
In conjunction with attached drawing, the utility model preferred embodiment is described in further details.
A kind of sealing cover for automatic adjusument hinged closure structure as shown in figure 1-3, including circular cover body 1,
It is mounting hole 2 among circular cover body 1,1 side of circular cover body is provided with location hole 3, is connect by positioning pin with location hole 3
Sealing cover can be installed.1 upper surface of circular cover body is equipped with groove 4, is used for shock mount in groove 4, plays tune
Save the effect of sealing cover position.It is equipped with seal groove 5 on the inside of mounting hole 2, sealing ring is installed in the seal groove 5, by close
Seal and pin shaft are interference fitted, so as to form closed hinged closure space.
1 lower surface of circular cover body is equipped with lug boss 6, the lug boss 6 height raised on 1 lower surface of circular cover body
Degree is 0.2mm-2mm, uses height for 0.5mm in the present embodiment, allows wear height, prevents abrasion entire surface.Inside groove 4
The spring that decrement is 1.5mm can be installed, closely matched so that lug boss 6 and sleeve end face are always maintained in the case where wearing
It closes, to achieve the purpose that long term seal, effectively extends chain service life.
Above-described embodiment is only used for illustrating the utility model design of the utility model, rather than to the utility model right
The restriction of protection, all non-essential modifications to the present invention made by this concept should all fall into the guarantor of the utility model
Protect range.
