Abstract
The utility model discloses a kind of novel seal bolt, it is characterized in that, stud is provided with in the side of polygonal spiral shell head, the joint diameter of described polygonal spiral shell head and stud is greater than the diameter of stud and polygonal spiral shell head, be respectively equipped with annular projection and screw section in the both sides of stud, be provided with annular seal groove in the intermediate portion of described annular projection.By above setting, the utility model is used for the sealing of machinery upper oil hole, solves oilhole surrounding oil leakage phenomenon, ensure that the safe handling of whole equipment.
Description
Technical field
The utility model relates to a kind of high-strength fastening piece, is novel seal bolt specifically.
Background technique
Bolt in current standard piece mostly is together with spiral shell head is connected directly between with stud, does not possess the dynamic function of sealing, is particularly used in the working environments such as oil circuit, very easily causes the leakage of oil of bolt surrounding.
Summary of the invention
The purpose of this utility model provides a kind of Novel bolt possessing sealing function.
To achieve these goals, the utility model is provided with stud in the side of polygonal spiral shell head, the joint diameter of described polygonal spiral shell head and stud is greater than the diameter of stud and polygonal spiral shell head, be respectively equipped with annular projection and screw section in the both sides of stud, be provided with annular seal groove in the intermediate portion of described annular projection.
By above setting, the utility model is used for the sealing of machinery upper oil hole, solves oilhole surrounding oil leakage phenomenon, ensure that the safe handling of whole equipment.
Accompanying drawing explanation
Now the utility model is described in further detail by reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation after placing seal ring.
In figure: 1, polygonal spiral shell head, 2, stud, 3, annular projection, 4, screw section, 5, annular seal groove, 6, seal ring.
Embodiment
As shown in Figure 1, 2, the utility model is provided with stud 2 in the side of polygonal spiral shell head 1, described polygonal spiral shell head 1 and the joint diameter of stud 2 are greater than the diameter of stud 2 and polygonal spiral shell head 1, be respectively equipped with annular projection 3 and screw section 4 in the both sides of stud 2, be provided with annular seal groove 5 in the intermediate portion of described annular projection 3.By above setting, the sealing of the utility model machinery upper oil hole, seal ring 6 is put in annular seal groove 5, screw section 4 is inserted the oilhole needing sealing, spinning polygon spiral shell head 1, screw section 4 is tightened with the screw-internal thread fit in oilhole, and seal ring 6 is formed with the inwall of oilhole and seals, and reduces the rate of fault of equipment.
