Abstract
The utility model relates to an engine anti-leakage structure for a commercial vehicle, which comprises a bolt and a nut matched with the bolt; an annular groove is formed on the inner surface of the nut; and an elastic ring is arranged in the annular groove. The utility model can better satisfy the sealing effect by adopting a fixing structure.
Description
Technical field
The utility model relates to a kind of leakage proof structure of sealing, especially relates to a kind of commercial vehicle engine leakage proof structure.
Background technique
Present commercial vehicle engine leakage proof structure is normally with leakproof pad, nut, bolt.Because the existing fixedly nut of usefulness and the surface of contact of leakproof pad are the plane, in use the seepage phenomenon can occur.
The model utility content
The technical problems to be solved in the utility model provides a kind of commercial vehicle engine leakage proof structure; This structure can be good at satisfying seal action.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: it comprise bolt, with the nut of bolt coupling; Described nut inner plane is provided with circular groove, is provided with elastic ring in this circular groove, in use by the nut applied pressure elastic ring compression is produced interference, plays seal action.
The utility model can be good at satisfying seal action.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to shown in Figure 1, be a kind of embodiment of the present utility model, among this embodiment, the cover plate 1 of motor fixes by leakproof fixed structure of the present utility model; Bolt 2 passes cover plate 1, and the nut 3 that mates with bolt 2 is fixed on the bolt 2; The plane that described nut 3 contacts with cover plate 1 is provided with circular groove 31, is provided with elastic ring 32 in this circular groove 31, and in use by nut 3 applied pressures, 1 of elastic ring 32 and cover plate, described elastic ring 32 is compressed and can produces interference, plays seal action.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
