Abstract
The utility model aims to provide a sealing bolt convenient in assembly and fine in sealing. The sealing bolt comprises a body and a nut. Key points include that the nut is round with a lateral face provided with an annular groove, and a resilient gasket is mounted inside the annular groove and has outer diameter slightly larger than that of the nut. In assembly, sealing of a bolt hole can be achieved by screwing the round nut into the bolt hole so as to lead the resilient gasket inside the annular groove of the nut to be tightly attached with the inner wall of the bolt hole, thereby effectively preventing lubricating oil from leaking. The sealing bolt has simple structure, fine sealing and convenient assembly, and is suitably applicable to various occasions.
Description
Technical field
The utility model belongs to mechanical industry, specially refers to bolt.
Background technique
Bolt in the market has only basic interconnect function, two parts is connected, is fixed into one with bolt that is:, and is poor because of sealing effect when this kind bolt is used in the many position of lubricant oil, tends to the outside leakage of oil along the nut place.For preventing leakage of oil, there is the people to add that at the nut place sealer remedies, but the DeGrain of sealer, but also rubbed easily etc., can not be used in the place of easy generation scratching, limited using scope, because increased coating process, make efficiency of assembling reduce in addition.
The model utility content
The purpose of this utility model is the sealing bolt that proposes a kind of easy to assembly, good seal.
Sealing bolt of the present utility model comprises the body of bolt and nut, and key is described nut for circular, and its side is provided with circular groove, and elastic seal ring is installed in the described circular groove, and the external diameter of described elastic seal ring is slightly larger than the external diameter of nut.
When assembling, the nut screw-in bolt hole with circle fits tightly the interior elastic seal ring of nut circular groove and the inwall of bolt hole, and bolt hole is formed sealing, can effectively prevent oil leakage.
For conveniently installing and reducing the axial length of installation that is connected part, make bolt of the present utility model can be used for the less occasion in space, the top of described nut is provided with the polygonal mounting hole of indent, so just whole nut all can be screwed in the bolt hole.
The bottom periphery of described seal ring is provided with ring-shaped step, and the external diameter of the cell wall of the close body of bolt one side of described circular groove is less than the internal diameter of ring-shaped step, and the bottom surface of described ring-shaped step protrudes in the bottom surface of circular groove near the cell wall of the body of bolt one side.After the bolt of said structure was installed, the bottom surface of its seal ring ring-shaped step and the end face of bolt hole fitted tightly, and the periphery of its seal ring and the side of bolt hole fit tightly, and be better to the sealing effect of bolt hole like this.
The described body of bolt comprises ganoid body of bolt body, and the head end of body of bolt body is provided with the step of diameter less than body of bolt body diameter, and described step is carved with screw thread.This kind bolt is applicable to the occasion that only connects rather than fix two parts, because body of bolt body surface is smooth, has only a part in two parts to be connected by screw thread and bolt, such two parts just are joined together and can relatively rotate, and are specially adapted to the fixing of the moving rail of timing system of motor and orbit determination and are connected.
Simple in structure, the good seal of sealing bolt of the present utility model, easy to assembly, be fit to be applied to multiple occasion.

Embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 1, 2, the sealing bolt of present embodiment comprises the body of bolt 2 and the nut 1 that alloyed steel is made, key is that described nut 1 is for circular, its side is provided with circular groove 5, accompany the elastic seal ring 6 that rubber is made between the cell wall 3,4 of described circular groove 5, the external diameter of described elastic seal ring 6 is slightly larger than the external diameter of nut 1; The top of nut 1 is provided with the Hexagon mounting hole 7 of indent; The described body of bolt 2 comprises ganoid body of bolt body 8, and the head end of body of bolt body 8 is provided with the step 9 of diameter less than body of bolt body 8 diameters, and described step 9 is carved with screw thread.
As shown in Figure 3, when assembling, the nut 1 of circle is screwed in the saturating bolt hole 13 of part 11, make the thread engagement of the screw thread and the part 12 of step 9, utilize the interaction of nut 1 and step 9 that part 11,12 is connected, elastic seal ring 6 in the nut circular groove fits tightly with the inwall of bolt hole 13, and bolt hole 13 is formed sealing, can effectively prevent oil leakage.Because body of bolt smooth surface, has only a part in two parts to be connected by screw thread and bolt, such two parts just are joined together and can relatively rotate, body of bolt body 8 can prevent that with the junction of step 9 part 12 from coming off, and is specially adapted to the fixing of the moving rail of timing system of motor and orbit determination and is connected.
Embodiment 2:
As shown in Figure 4, as different from Example 1, the bottom periphery of the seal ring 6 of the sealing bolt of present embodiment is provided with ring-shaped step 10, the external diameter of the cell wall 4 of the close body of bolt one side of described circular groove is less than the internal diameter of ring-shaped step 10, and the bottom surface of described ring-shaped step 10 protrudes in the bottom surface of circular groove near the cell wall 4 of the body of bolt one side.As shown in Figure 5, after the bolt of present embodiment is installed, the interaction of nut 1 and step 9 is connected part 11,12, the bottom surface of bolt seal circle ring-shaped step 10 and the end face of bolt hole 13 fit tightly, the side of the periphery of its seal ring 6 and bolt hole 13 fits tightly, and is better to the sealing effect of bolt hole like this.
