Description
Technical field
The utility model relates to a kind of sealing rings, refer in particular to a kind of coal mine hydraulic supporting composite sealing ring.
Background technique
It is mainly used on coal industry hydraulic support column, is a kind of common accessory, effect is to prevent hydraulic cylinder from letting out
Dew causes hydraulic direct protective function to be affected, currently, existing ring structure is simple, and with the use of when, there are fastnesses
Difference, the defect that whole compactness is poor and anti-interference ability is low cause centainly to cause the decline of sealing performance to using
Influence.
Utility model content
The shortcomings that in order to overcome background technique and shortcoming, the utility model provide a kind of coal mine hydraulic supporting with compound
Sealing ring, it is poor mainly to solve existing coal mine hydraulic supporting sealing ring there are compactnesses, and anti-interference ability is low and sealing performance
Low technical problem.
The technical solution of the utility model is: a kind of coal mine hydraulic supporting composite sealing ring, it is characterised in that: including interior
Sealing ring and exterior seal ring, the outer surface of the inner seal ring and the inner surface of exterior seal ring are bonded to each other, the inner seal ring
Outer surface be equipped with the first arc groove, the inner surface of the exterior seal ring is equipped with the second arc groove, first arc groove and the
Two arc grooves form annular groove, and the annular groove is equipped with the reinforcing ring to match with it, and the side of the reinforcing ring is located at described
In first arc groove, the other side of the reinforcing ring is located in the second arc groove.
Further, first arc groove and the second arc groove are semicircular arc slot, and the section of the reinforcing ring is circle
Shape.
Further, the upper and lower end face of the exterior seal ring and inner seal ring mutually maintains an equal level, the inner surface of the inner seal ring
Section is plane, and the section of the outer surface of the exterior seal ring is trapezium structure, including outer surface, top incline and is had a down dip
Inclined-plane, the upper end of the outer surface pass through the upper surface phase transition of top incline and exterior seal ring, under the outer surface
End passes through the lower end surface phase transition of bottom incline and exterior seal ring.
Further, the reinforcing ring is made of elastic rubber material.
The utility model has the following beneficial effects: coal mine hydraulic supporting composite sealing ring uses double-layer structure, and
Reinforcing ring is added in inside, improves the whole compactness and stability of sealing ring, anti-interference ability is improved, to effectively improve close
Sealing property enhances the service performance of product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is schematic enlarged-scale view at the A in the utility model Fig. 1.
In figure, inner seal ring 1, exterior seal ring 2, outer surface 21, top incline 22, bottom incline 23, the first arc groove
3, the second arc groove 4, bottom incline 23, annular groove 5, reinforcing ring 6.
Specific embodiment
The embodiments of the present invention are described further below for attached drawing:
As shown, a kind of coal mine hydraulic supporting composite sealing ring, including inner seal ring 1 and exterior seal ring 2, it is described interior
The outer surface of sealing ring 1 and the inner surface of exterior seal ring 2 are bonded to each other, and the outer surface of the inner seal ring 1 is equipped with the first arc
The inner surface of slot 3, the exterior seal ring 2 is equipped with the second arc groove 4, and first arc groove 3 and the second arc groove 4 form annular
Slot 5, the annular groove 5 are equipped with the reinforcing ring 6 to match with it, and the side of the reinforcing ring 6 is located at first arc groove 3
Interior, the other side of the reinforcing ring 6 is located in the second arc groove 4.According to above scheme, the coal mine hydraulic supporting compound seal
Circle uses double-layer structure, and adds reinforcing ring in inside, improves the whole compactness and stability of sealing ring, improves anti-interference energy
Power enhances the service performance of product to effectively improve sealing performance.
In the present invention, first arc groove 3 and the second arc groove 4 are semicircular arc slot, the reinforcing ring 6
Section be circle.First arc groove and the second arc groove are semicircular arc slot, and reinforcing ring is placed in arc groove, using above-mentioned knot
Structure has many advantages, such as structurally reasonable, distribution equilibrium.
In the present invention, the upper and lower end face of the exterior seal ring 2 and inner seal ring 1 mutually maintains an equal level, the interior sealing
The inner surface section of circle 1 is plane, and the section of the outer surface of the exterior seal ring 2 is trapezium structure, and the exterior seal ring 2 includes
Outer surface 21, top incline 22 and bottom incline 23, the upper end of the outer surface 21 by top incline 22 with it is outer close
The upper surface phase transition of seal 2, the lower end of the outer surface 21 pass through the lower end surface of bottom incline 23 and exterior seal ring 2 mutually mistake
It crosses.By above structure, exterior seal ring 2 combines top incline 22 and bottom incline 23, inclined surface stress using outer surface 21
When, enable to what exterior seal ring and inner seal ring can be even closer to be bonded, effectively enhancing sealing performance.In addition, described add
Strong ring 6 is made of elastic rubber material, and crushing resistance enhancing improves the strength and stability of sealing ring.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
