Description
Technical Field
The invention belongs to the technical field of sealing rings, and particularly relates to an inverted L-shaped sealing ring for sealing a nonmetal elastomer material in a closed space.
Background
The bridge support is a key part for connecting the upper structure of the bridge and the bridge pier, bears huge bridge load on one hand, and also needs to adapt to the expansion and deflection rotation deformation of the beam on the other hand. Bridge bearings have many different structural styles, and among them, a basin-type rubber bearing is a bridge bearing which is used more generally. Referring to fig. 1 and 2, in the conventional pot-type rubber mount structure, rubber is confined in a metal pot to bear bridge load acting on the rubber through a metal lining plate, while rotation generated by uneven compression of the rubber accommodates flexural deformation of a beam. In order to prevent rubber from being extruded out of a gap between the metal basin and the metal lining plate under the action of huge pressure, two circular copper sealing rings with openings are arranged among the rubber, the metal basin and the metal lining plate, the openings of the two copper sealing rings are overlapped in a staggered mode, and the rubber is prevented from being extruded out of the openings.
The sealing ring structure has the advantages of simple manufacture, material saving and low cost, and has the defects of defective sealing effect and small gap between the copper sealing ring and the metal basin. When the stress of the rubber is large, the rubber is also extruded from the small gap. Therefore, in the design of the pot rubber mount, the allowable load force of the rubber is controlled to be 30MPa or less, and even then, in the pot rubber mount used in the past, it is found that the rubber is extruded from the metal pot.

For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
As shown in fig. 3 and 4: the embodiment discloses an inverted L-shaped sealing ring which is arranged in a metal closed space surrounded by metal; the metal closed space is a closed space formed by a metal basin 3 and a metal lining plate 1 arranged at the opening part of the metal basin 3;
as shown in fig. 3 and 5:
the concave space of the metal basin 3 is cylindrical or circular, and the bottom surface is plane or curved;
the metal lining plate 1 is cylindrical corresponding to the metal basin 3 with the cylindrical concave space.
The metal lining plate 1 is in a circular basin shape or a cylindrical shape corresponding to the metal basin 3 with the circular ring-shaped concave space; the metal closed space is provided with a non-metal elastomer 2; the lower surface and the upper surface of the non-metal elastomer 2 are respectively contacted with the metal basin 3 and the metal lining plate 1; the side elevation of the non-metal elastomer 2 is contacted with the side elevation of the metal basin 3.
In this embodiment, when the concave space of the metal basin 3 is cylindrical, the non-metal elastomer 2 is cylindrical. When the concave space of the metal basin 3 is a circular ring, the non-metal elastomer 2 is a cylinder.
In this embodiment, the seal ring is installed between the non-metal elastomer 2, the metal basin 3 and the metal liner plate 1.
In this embodiment, when the non-metal elastic body 2 is cylindrical, the number of the sealing rings 5 is one, and the sealing rings are disposed at the junction between the upper surface and the side vertical surface of the non-metal elastic body 2.
Specifically, the outer circular vertical surface of the sealing ring 5 is in contact with the inner circular vertical surface of the metal basin 3; the top surface of the sealing ring 5 is contacted with the metal lining plate 1; the inner side surface of the sealing ring 5 is in contact with the nonmetal elastic body 2.
As shown in fig. 5 and 6: in this embodiment, when the non-metal elastic body 2 is cylindrical, the number of the sealing rings 5 is two, and the two sealing rings are respectively disposed at a boundary between the upper surface of the non-metal elastic body 2 and the inner vertical surface and a boundary between the upper surface and the outer vertical surface.
In this embodiment, the outer circular vertical surface of the sealing ring 5 disposed on the outer side is in contact with the outer circular vertical surface of the concave space of the metal basin 3, the top surface of the sealing ring 5 is in contact with the metal lining plate 1, and the inner side surface of the sealing ring 5 is in contact with the non-metal elastic body 2.
The inner side circular vertical face of the sealing ring 5 arranged on the inner side is contacted with the inner side circular vertical face of the concave space of the metal basin 3, the top surface of the sealing ring 5 is contacted with the metal lining plate 1, and the outer side surface of the sealing ring 5 is contacted with the nonmetal elastic body 2.
In this embodiment, the material of the sealing ring 5 is a metal material or a non-metal material.
In this embodiment, the material of the sealing ring 5 is brass or stainless steel.
The material of the non-metallic elastomer 2 in this embodiment is rubber or polyurethane.
In this embodiment, when the airtight space of metal is basin formula rubber support, basin formula rubber support includes: the device comprises a nonmetal elastomer 2, a metal basin 3, a metal lining plate 1 and an inverted L-shaped metal sealing ring 5; the inverted L-shaped metal sealing ring 5 is arranged among the non-metal elastomer 2, the metal basin 3 and the metal lining plate 1.

When the nonmetal elastomer 2 acts on the vertical part of the inverted L-shaped metal sealing ring 5 under the action of the huge pressure of the metal lining plate 1, the nonmetal elastomer laterally expands to form extrusion on the inner vertical surface of the metal basin 3, so that a tiny gap between the metal basin 3 and the sealing ring 5 caused by machining errors is eliminated, and the nonmetal elastomer 2 is completely in a sealed state.
The larger the pressure stress of the rubber is, the larger the side pressure of the inverted-L-shaped metal sealing ring 5 to the metal basin 3 is, and as long as the metal basin 3 has enough rigidity to bear the lateral pressure of the rubber, the inverted-L-shaped metal sealing ring 5 can form a complete seal for the non-metal elastic body 2.
Tests prove that the rubber extrusion phenomenon occurs when the compressive stress of the rubber reaches 45MPa by adopting the open copper sealing ring, while the extrusion phenomenon does not occur on the nonmetal elastomer when the compressive stress of the rubber reaches 180MP by adopting the inverted L-shaped metal sealing ring in the embodiment, and the nonmetal elastomer is intact.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
