Detailed Description
First, as shown in fig. 1, a sealing strip 100 used in the prior art and a connection method thereof with a base plate 20 and a metering plate 40 are shown. Referring to fig. 2, the sealing strip 100 is engaged with the metering plate 40 and the bottom plate 20, and is fixed by a large amount of glue, and in actual operation, the assembly meeting the standard needs a complex process.
Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
The present application provides a sealing structure 10, as shown in fig. 3, comprising a flat annular sealing ring 11, wherein the inner edge of the annular sealing ring 11 is provided with a vertically upwards extending protruding part 14. The flat ring seal 11 is easily sandwiched between the two plates. The upwardly extending boss 14 primarily serves as a seal against a particular device or between the device and the environment.
Wherein, as shown in fig. 3, the outer side of the bulge 14 is vertical to the annular sealing ring 11; the inner side of the protruding part 14 is provided with a concave cambered surface, so that the thickness of the protruding part 14 gradually increases from the top end to the bottom end.
In this embodiment, the annular seal ring 11 is made of rubber. In other embodiments, other annular sealing rings 11 may be used, such as: resins, plastics, and the like.
As shown in fig. 3, a plurality of mounting holes 13 are uniformly formed on the annular seal ring 11 for fixing the annular seal ring 11 to a device. The annular sealing ring 11 is fixed through the mounting hole 13 by using the bolt, so that the use of glue in the reassembling process can be reduced or stopped, and the assembling difficulty can be greatly reduced.
As shown in fig. 3, a plurality of positioning protrusions 12 are disposed on the upper surface of the annular sealing ring 11, so as to fix the relative positions of the annular sealing ring 11 and the device.
In this embodiment, the plurality of positioning protrusions 12 are uniformly disposed between the plurality of mounting holes 13, so that the design can avoid the single positioning protrusion 12 from being subjected to excessive stress and reduce the deformation of the annular seal ring 11. In other embodiments, the positioning projections 12 may be provided at other locations.
In the present embodiment, the annular seal ring 11 is a waist-shaped annular seal ring 11. In other embodiments, other shapes of the annular seal ring 11 are possible in order to adapt to different devices or apparatuses.
In this embodiment, the annular sealing ring 11 is formed by one-step molding, which eliminates the need of secondary processing the sealing strip 100 into an annular shape in the prior art, and makes the assembly steps more complicated when the sealing strip 100 which is processed into an annular shape is assembled by matching with the special-shaped holes. The one-time formed annular sealing ring 11 can process the shape of the annular sealing ring 11 according to different special-shaped holes to be assembled, so that the assembly difficulty is reduced.
The present application also provides a carrier having a sealing structure, as shown in fig. 4, 5 and 6, for housing an aircraft device 200, comprising: the bottom plate 20 is the bottom side of the bracket, and a first waist-shaped hole is formed in the middle of the bottom plate; the reinforcing plate 30 is in a flat plate shape and is arranged on the upper surface of the bottom plate 20, and a second waist-shaped hole which is the same as the first waist-shaped hole in size and aligned with the first waist-shaped hole in position is formed in the middle of the reinforcing plate; the metering plate 40 is in a flat plate shape and is arranged at the lower side of the bottom plate 20, the metering plate 40 covers the first waist-shaped hole, and a plurality of heat dissipation holes are formed in the metering plate 40, so that a refrigerating air source can be conveniently blown in; the sealing structure 10 is arranged between the bottom plate 20 and the metering plate 40, and the vertically upward extending protruding part 14 of the annular sealing ring 11 extends into the first waist-shaped hole and the second waist-shaped hole to be in contact with the edges of the first waist-shaped hole and the second waist-shaped hole.
In this embodiment, the bottom plate 20, the reinforcing plate 30 and the measuring plate 40 are all metal sheet metal parts, which have high rigidity, are not easy to deform and are easy to process.
As shown in fig. 6, a plurality of positioning grooves 21 are formed on the lower side of the bottom plate 20 and matched with the positioning protrusions 12, and when the assembly is performed, the positioning protrusions 12 are first extended into the positioning grooves 21 to perform an auxiliary positioning function. In addition, the positioning projection 12 also serves to prevent displacement, and as shown in fig. 7, the aviation apparatus 200 needs to be pushed in the direction of the arrow shown in the drawing at the bottom of the bracket and tightly combined with the connector 300 on the bracket when being mounted. In this process, friction is inevitably generated between the bottom of the aviation device 200 and the protruding portion 14 of the annular sealing ring 11, and if the annular sealing ring 11 is fixed only by the clamping force between the bottom plate 20 and the metering plate 40, a small amount of movement or deformation may be generated when the radial friction force is applied, so that the sealing performance is reduced. The positioning protrusion 12 and the positioning groove 21 can effectively prevent the annular sealing ring 11 from being displaced or deformed after being combined.
Wherein, a plurality of first bolt holes 22 which are matched with the plurality of mounting holes 13 are arranged around the first waist-shaped holes and the second waist-shaped holes, and a plurality of second bolt holes 41 which are matched with the plurality of first bolt holes 22 are arranged on the metering plate 40. In the assembly process, as shown in fig. 6, bolts sequentially pass through the first bolt holes 22, the mounting holes 13 and the second bolt holes 41, and are fastened and fixed by nuts, so as to complete the fixed installation of the structures of the reinforcing plate 30, the bottom plate 20, the ring-shaped sealing ring 11 and the metering plate 40 from top to bottom as shown in fig. 8. .
The bulge 14 is attached to the bottom of the aviation device 200 placed on the bracket in a sealing manner, so that the bulge 14 can seal a gap between the aviation device 200 placed in the bracket and the reinforcing plate 30, and cooling air is prevented from losing a cooling air source due to the gap between the aviation device 200 and the reinforcing plate 30 when the cooling air is blown into the holes under the device through the metering plate 40, so that cooling efficiency is improved. In addition, when the aviation apparatus 200 is disposed on the bracket, the protrusion 14 is pressed, and the protrusion 14 is deformed by pressure, thereby affecting the tightness of the sealing structure 10. The two connecting edges of the bulge 14 and the annular sealing ring 11 are vertically arranged on one side, and the design that the concave cambered surface is arranged on one side is adopted, so that when the bulge 14 deforms, as shown by the arrow direction in fig. 8, deformation of the bulge towards one side of the vertical edge tends to occur instead of random tilting towards two sides. Accordingly, the protrusions 14 are uniformly reversed at all positions according to the same rule, and the sealing structure 10 can still have good sealing performance after being pressed and deformed by the aviation equipment 200.
In addition, as shown in a partial view a of fig. 1, the bottom plate 20 of the related art requires an additional bending process at the time of the process molding to adapt to the assembly of the weather strip 100. In the actual manufacturing process, the base plate 20 needs to be separately opened for press forming according to the shape specificity, so that the processing cost and the processing steps and time are increased. With the sealing structure 10 provided by the application, the bottom plate 20 is a flat sheet metal part, and separate die sinking and stamping forming are not needed, so that the processing cost is reduced, the processing steps are simplified, and the processing efficiency is improved.
In addition, as shown in a partial view a of fig. 1, in the prior art, the measuring plate 40 and the bottom plate 20 are connected only by the sealing strip 100, which results in poor rigidity of the whole structure, and after the assembly is completed, the sealing strip 100 is often deformed seriously, so that the sealing performance is reduced, and the measuring plate 40 is further displaced to a certain extent, so that the sealing performance of the sealing strip is further affected. As shown in fig. 5, the sealing structure 10 and the bracket with the sealing structure according to the embodiments of the present application are provided, the annular sealing ring 11, the metering plate 40 and the bottom plate 20 are fixedly connected by using bolts, the annular sealing ring 11 is sandwiched by the metering plate 40 and the bottom plate 20 made of metal, and all the three are in plane contact, so that the annular sealing ring 11 is not easy to deform, and the tightness of the overall structure is ensured.
