Description
Technical Field
The utility model relates to the technical field of bolts, in particular to a bolt connecting structure.
Background
In the mechanical industry, machines are required to withstand various environments, and the industry has higher and higher requirements on the anti-leakage performance of the bolt connection position of the plate body. Generally, after the bolt is locked, the rubber washer can reduce the chance of the bolt contacting moisture, thereby reducing liquid leakage and simultaneously reducing the occurrence of bolt corrosion. However, many rubber gaskets have been improved in their own structure so far, and their waterproof effect is common.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a bolt connecting structure which can improve the anti-seepage performance of a bolt connection part of a plate body.
The purpose of the utility model is realized by adopting the following technical scheme:
the bolt connecting structure comprises two plate bodies, a nut and a bolt, wherein the two plate bodies are mutually overlapped, a screw rod of the bolt penetrates through the two plate bodies, a rubber gasket is sleeved on the screw rod, the local part of the rubber gasket is positioned in the annular groove, the nut is in threaded connection with the screw rod, the two plate bodies are respectively abutted by the nut and the rubber gasket, at least two rubber sealing strips are arranged between the two plate bodies, and the rubber sealing strips are respectively positioned on two sides of the bolt.
Specifically, the number of the bolts is plural, each of the bolts is arranged along a straight line, and the rubber seal strip is arranged along the arrangement of the bolts.
Specifically, the rubber gasket is made of butadiene-acrylonitrile rubber.
Specifically, the rubber sealing strip is made of butyl rubber.
Specifically, the rubber sealing strip is in a viscous state, and the rubber sealing strip is adhered between the two plate bodies.
Specifically, the plate body is a flat plate or a curved plate.
Specifically, the longitudinal section of the rubber gasket is square.
Specifically, the annular groove is formed in the root of the screw.
Compared with the prior art, the utility model has the beneficial effects that:
the structure of the bolt is improved, and an annular groove is arranged on the bottom wall of the outer flange of the bolt. After the two plate bodies are locked together by the nut and the bolt, the rubber gasket is pressed to deform, one side of the rubber gasket is tightly attached to the plate body, and the other side of the rubber gasket is tightly attached to the annular groove, so that the tightly attaching positions of the liquid entering the rubber gasket, the plate body and the annular groove can be reduced.
The rubber gasket is arranged in the groove, and when the nut is screwed down, the rubber gasket cannot be damaged, so that the damage rate of the rubber gasket is reduced.
The rubber sealing strips on the two sides of the bolt connection position of the plate body are adhered between the two plate bodies, so that the leakage condition of the two sides of the bolt connection position of the plate body can be reduced.
The bolt and the bolt connecting structure can improve the anti-seepage performance of the bolt connection part of the plate body by one grade, and simultaneously prolong the service life of the rubber gasket.
Drawings
FIG. 1 is a perspective view of a bolt connection;
fig. 2 is a sectional view of the bolt coupling structure.
In the figure: 1. an outer flange; 11. an annular groove; 2. a plate body; 3. a nut; 4. a rubber gasket; 5. a rubber sealing strip.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Referring to fig. 1 and 2, the bolt connection structure includes two plate bodies 2, a nut 3 and a bolt. The head bottom edge of bolt is equipped with outward flange 1, and the diapire of outward flange 1 is equipped with annular groove 11. The annular groove 11 is provided at the screw root of the bolt. The two plate bodies 2 are mutually superposed, and the screw of the bolt passes through the two plate bodies 2. The screw rod is sleeved with a rubber gasket 4, and the rubber gasket 4 is partially positioned in the annular groove 11. The nut 3 is in threaded connection with the screw, and the two plate bodies 2 are respectively abutted by the nut 3 and the rubber washer 4, so that the two plate bodies 2 are close to each other. At least two rubber sealing strips 5 are arranged between the two plate bodies 2, and the rubber sealing strips 5 are respectively positioned on two sides of the bolt.
Specifically, the number of bolts is plural, the bolts are arranged in a straight line, and the rubber seal 5 is provided along the arrangement of the bolts.
Specifically, the rubber gasket 4 is made of butadiene-acrylonitrile rubber.
Specifically, the rubber seal strip 5 is made of butyl rubber.
Specifically, the rubber sealing strip 5 is in a sticky state, and the rubber sealing strip 5 is adhered between the two plate bodies 2, so that two sides of the bolt connection position of the plate bodies form sealing.
Specifically, the plate body 2 is a flat plate or a curved plate (not shown).
Specifically, the longitudinal section of the rubber grommet 4 is square.
The bolt connecting structure has the beneficial effects that:
the structure of the bolt is improved, and an annular groove 11 is arranged on the bottom wall of the outer flange 1 of the bolt. After the nut 3 and the bolt lock the two plate bodies 2 together, the rubber gasket 4 is deformed under pressure, one side of the rubber gasket 4 is tightly attached to the plate body 2, and the other side of the rubber gasket 4 is tightly attached to the annular groove 11, so that the tightly attaching positions of the rubber gasket 4, the plate body 2 and the annular groove 11 can be reduced.
The rubber gasket 4 is arranged in the groove, and when the nut 3 is screwed down, the rubber gasket 4 cannot be damaged, so that the damage rate of the rubber gasket 4 is reduced.
The rubber sealing strips 5 on the two sides of the plate body bolt connection position are adhered between the two plate bodies 2, so that the leakage condition on the two sides of the plate body bolt connection position can be reduced.
The bolt connecting structure can improve the anti-seepage performance of the bolt connection part of the plate body by one grade, and simultaneously, the service life of the rubber gasket 4 is longer.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
