Description

Technical Field

[0001] The invention relates to the technical field of metal gaskets, and in particular to a metal sealing gasket that is easy to replace and use, and a method for using the same. Background Art

[0002] In the patent application with application publication number CN112196885B, it includes an annular body, a partition and two gasket assemblies. The annular body is provided with a partition that divides it into two upper and lower receiving grooves. The partition is provided with a through hole. The receiving grooves are provided with a gasket assembly. The gasket assembly is composed of two half-edge gaskets. The partition is fixedly inlaid with a number of magnets. The advantages are: the gasket assembly is composed of two half-edge gaskets, and the partition is fixedly inlaid with a number of magnets, which can be easily disassembled and assembled, and improve work efficiency; the through hole is a T-shaped hole with a large upper part and a small lower part. The partition is provided with a groove for connecting the notch with the large diameter section of the through hole. A felt pad is provided in the groove to facilitate the injection and storage of lubricating oil, which is beneficial to the lubrication of the connection position, reduces the wear rate, and improves the service life.

[0003] In the prior art including the above-mentioned patents, the gasket is in two halves and connected by magnetic attraction. When the bolts or screws are tightened for fixing, a downward pressing rotational force is generated. The rotational force increases as the screws or bolts are tightened. After the increase, it will be greater than the magnetic attraction between the two gaskets. At this time, the two gaskets will be separated and a good gasketing effect cannot be achieved. In addition, lubrication through the felt pad will cause the entire gasket to be contaminated with lubricating oil and cannot be effectively replenished at a fixed point. Summary of the invention

[0004] The problem to be solved by the present invention is that the integrated gasket is inconvenient to disassemble and assemble, the split gasket will move to both sides under the spinning pressure and cannot be completely closed, and the bolts on the machine are easy to loosen and the sealing performance is poor.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a metal sealing gasket that is easy to replace and use and a method for using the same, comprising a gasket, a baffle is provided on one side of the gasket, the gasket and the baffle are both semi-arc-shaped, a groove is provided on the top of the baffle, a convex block is fixedly provided on the bottom of the front side of the baffle, and the convex block is adapted to the groove, a cavity is provided inside the gasket, a spring plate is provided inside the cavity, a support block is provided on the top of the spring plate, the bottom of the support block is fixedly connected to the bottom of the inner wall of the cavity, a connecting block is provided on the bottom of the spring plate, and the top of the connecting block is fixedly connected to the top of the inner wall of the cavity, a plurality of damping blocks are arranged in a circular array on one side of the spring plate, one side of the damping block penetrates the gasket and extends to the outside of the gasket, a connecting pipe penetrates the inside of the gasket, a rubber sheet is provided on the top of the front side of the connecting pipe, a lubrication pipe is fixedly connected to the back side of the connecting pipe, three outlets are provided on one side of the lubrication pipe, one side of the lubrication pipe penetrates the baffle and extends to the outside of the baffle, and a bolt is provided on the front side of the gasket.

[0006] S1: When using, align the two gaskets with each other, align the protrusion with the groove, and then merge the two semicircular gaskets into a whole circular gasket. Then you can install the bolt. As the bolt continues to move down, a rotational pressure will be generated when the bolt is tightened. At this time, the two gaskets that fit each other can be buckled with each other through the protrusion and the groove and will not separate.

[0007] S2: As the bolt is tightened continuously, the outer wall of the bolt will contact the damping block, and the baffle plate and the gasket will form a sunken shape to wrap a part of the outer wall of the bolt. At this time, the damping block will exert pressure on the spring plate. After the spring plate is stressed, it will generate a rebound force in the reverse direction through its own structure and the cooperation between the support block and the connecting block. The damping block can increase a clamping force on the outer surface of the bolt, so that the bolt is not easy to loosen after tightening, and the sealing performance of the bolt after tightening is stronger;

[0008] S3: If the bolts or washers are exposed to open air or humid environment for a long time, causing the internal threads of the bolts to rust and become difficult to remove, or if lubrication is required inside, rust remover or lubricating oil can be added to the center of the bolts and washers through the connecting pipe. When adding, the rust remover or lubricating oil nozzle needs to be directly inserted into the connecting pipe through the rubber sheet through a straight pipe. The discharged liquid will flow into the center of the bolts and washers along the liquid outlet of the lubrication pipe.

[0009] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0010] (1) The gasket is split and has grooves and convex blocks on its surface. The convex blocks and grooves cooperate to form an interlocking mutual force. When the two gaskets are combined into a complete gasket, they will be interlocked with each other and will not be separated when subjected to the downward pressure and rotational force of bolts and screws. The gaskets are combined in a stacked manner, which is convenient for disassembly and assembly. When replacing, the screws do not need to be completely removed, and only need to be loosened a certain distance to separate the two gaskets. The gasket can be combined with the baffle to become a sunken wrapping type, and a damping block is provided on the inner circle of the gasket. The damping block can add a clamping force to the outer surface of the bolt through the cooperation with the spring plate, increase the friction between the outer surface of the bolt and make it more firm. It can also prevent the bolt from loosening, improve the cooperation between the gasket and the bolt, and make the sealing between the two better;

[0011] (2) A lubrication tube and a connecting tube are provided between the gasket and the baffle. The user can use the lubrication tube to lubricate or remove rust from the center point of the connection between the gasket and the bolt. Fixed-point addition is more efficient in both lubrication and rust removal. A rubber sheet is provided on the surface of the pipe mouth of the connecting tube. The rubber sheet can block water, dust, etc. in daily life to avoid clogging of the connecting tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figures 1 to 8 As shown, the present invention provides a metal sealing gasket that is easy to replace and use and a method for using the same, including a gasket 2, a baffle 6 is provided on one side of the gasket 2, the gasket 2 and the baffle 6 are both semi-arc-shaped, a groove 9 is provided on the top of the baffle 6, a protrusion 5 is fixedly provided on the bottom of the front side of the baffle 6, the protrusion 5 is adapted to the groove 9, a cavity is provided inside the gasket 2, a spring plate 10 is provided inside the cavity, a support block 11 is provided on the top of the spring plate 10, the bottom of the support block 11 is fixedly connected to the bottom of the inner wall of the cavity, and the bottom of the spring plate 10 is provided A connecting block 12, the top of the connecting block 12 is fixedly connected to the top of the inner wall of the cavity, one side of the spring plate 10 is arranged in a circular array with a number of damping blocks 8, one side of the damping block 8 passes through the gasket 2 and extends to the outside of the gasket 2, a connecting pipe 7 passes through the inside of the gasket 2, a rubber sheet 3 is provided on the top of the front of the connecting pipe 7, a lubrication pipe 4 is fixedly connected to the back of the connecting pipe 7, three outlets are provided on one side of the lubrication pipe 4, one side of the lubrication pipe 4 passes through the baffle 6 and extends to the outside of the baffle 6, and a bolt 1 is provided on the front of the gasket 2.

[0024] S1: When in use, align the two gaskets 2 with each other, align the protrusion 5 with the groove 9 after alignment, and merge the two semicircular gaskets 2 into an integral circular gasket 2 after alignment, and then install the bolt 1. As the bolt 1 continues to move downward, a rotation pressure will be generated when the bolt 1 is tightened. At this time, the two gaskets 2 that are matched and connected to each other can be buckled with each other through the protrusion 5 and the groove 9 and will not separate;

[0025] S2: As the bolt 1 is continuously tightened, the outer wall of the bolt 1 will contact the damping block 8, and the baffle 6 and the gasket 2 will form a sunken shape to wrap a part of the outer wall of the bolt 1. At this time, the damping block 8 will be forced to exert pressure on the spring plate 10. After the spring plate 10 is forced, it will generate a rebound force in the reverse direction through its own structure and the cooperation between the support block 11 and the connecting block 12. The damping block 8 can increase a clamping force on the outer surface of the bolt 1, so that the bolt 1 is not easy to loosen after being tightened, and the sealing performance of the bolt 1 after being tightened is stronger;

[0026] S3: If the bolt 1 or the gasket 2 is exposed to the open air or a relatively humid environment for a long time, causing the internal thread of the bolt 1 to rust and become difficult to disassemble, or if lubrication of the inside is required, the rust remover or lubricating oil can be added to the center position of the bolt 1 and the gasket 2 through the connecting pipe 7. When adding, the rust remover or lubricating oil nozzle needs to be directly inserted into the connecting pipe 7 through the rubber sheet 3 through a straight pipe. The discharged liquid will flow into the center position of the bolt 1 and the gasket 2 along the liquid outlet of the lubrication pipe 4.

[0027] The working principle and use process of the present invention are as follows: when in use, align the two gaskets 2 with each other, align the protrusion 5 with the groove 9 after alignment, merge the two semicircular gaskets 2 into an integral circular gasket 2 after alignment, and then install the bolt 1. As the bolt 1 continues to move downward, a rotational pressure will be generated when the bolt 1 is tightened. At this time, the two gaskets 2 that cooperate with each other can be buckled with each other through the protrusion 5 and the groove 9 and will not separate. As the bolt 1 continues to be tightened, the outer wall of the bolt 1 will contact the damping block 8, and the baffle 6 will cooperate with the gasket 2 to form a sunken shape to wrap a part of the outer wall of the bolt 1. At this time, the damping block 8 will be forced to apply pressure to the spring plate 10, and the spring plate 10 will be forced to pass through itself The structure of the bolt body and the cooperation between the support block 11 and the connecting block 12 generate a rebound force in the opposite direction. The damping block 8 can increase a clamping force on the outer surface of the bolt 1, so that the bolt 1 is not easy to loosen after being tightened. If the bolt 1 or the gasket 2 is exposed to the open air or a relatively humid environment for a long time, the internal thread of the bolt 1 will rust and become difficult to disassemble, or when lubrication is required, the rust remover or lubricating oil can be added to the center position of the bolt 1 and the gasket 2 through the connecting pipe 7. When adding, the rust remover or lubricating oil nozzle needs to be directly inserted into the connecting pipe 7 through the rubber sheet 3 through the straight pipe. The discharged liquid will flow into the center position of the bolt 1 and the gasket 2 along the liquid outlet of the lubrication pipe 4.
