Abstract
The utility model discloses a general gasoline engine box shell assembly, which comprises a box body and a box cover. An inner cavity is formed after the box body and the box cover are covered together. A central hole is arranged on the box cover; a central mounting hole is arranged at the center hole on the box body; the side wall of the box body is crosswise provided with a first and a second threaded hole; the side wall of the box cover is provided with a first and a second mounting through hole corresponding to the first and second threaded holes; a first bolt is respectively arranged in the first and second mounting through holes and the first and second threaded holes; the first bolts fixedly connect the box body with the box cover; a third threaded hole is arranged between the first and second threaded holes on the box boy; a third mounting through hole is arranged on the box cover corresponding to the third threaded hole; and a second bolt is arranged in the third mounting through hole and the third threaded hole. The utility model can efficiently improve the sealing property of the jointed surface between the box body and the box cover, can prevent the engine oil from overflowing and can ensure the normal running of the gear in the box body.
Description
Technical field
The utility model relates to all-purpose gasoline box body technical field, relates in particular to all-purpose gasoline box body housing assembly.
Background technique
Traditional all-purpose gasoline box body housing assembly, comprise casing and case lid, after both snap together, be formed with internal cavities, on case lid, be provided with center hole, on the casing to should central hole having center mounting hole, in described center mounting hole, the center hole gear is installed, simultaneously, for oilgear, guarantee that it runs well, also can splendid attire machine oil in the internal cavities of casing.Laterally have first and second tapped hole on the sidewall of described casing, to should first and second tapped hole place having first and second through hole is installed on the sidewall of described case lid, install in through hole, second tapped hole and all be equipped with first screw at the first installation through hole, first tapped hole and second, this first screw is fixedlyed connected described casing with case lid.When the high-speed gear in the casing turns round, meeting pressurized air, cause box house pressure to increase, again because the spacing of first and second tapped hole is bigger, so just make the sealing effect variation of casing and case lid junction plane, the machine oil in the casing will flow to outside the casing from the junction plane between two first screws, has not only influenced the normal operation of casing internal gear, and can cause the waste of machine oil, this technical barrier all is not eliminated for a long time.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of petrol engine casing housing assembly that can guarantee casing and case lid junction plane sealing effect.
The technical solution of the utility model is as follows: a kind of all-purpose gasoline box body housing assembly, comprise casing and case lid, after both snap together, be formed with internal cavities, on case lid, be provided with center hole, on the casing to should central hole having center mounting hole; On the sidewall of casing, laterally have first, two tapped holes, on the sidewall of described case lid to should first, two tapped hole places have first, two install through hole, first through hole is installed, first tapped hole and second is installed through hole, all be equipped with first screw in second tapped hole, this first screw is fixedlyed connected described casing with case lid, its key is: described first, have the 3rd tapped hole on the casing between two tapped holes, corresponding described the 3rd tapped hole place has the 3rd through hole is installed on case lid, in the 3rd installation through hole and the 3rd tapped hole second screw is housed.
The utility model is on the basis of conventional construction, on the casing between described first and second tapped hole, have the 3rd tapped hole, corresponding described the 3rd tapped hole place has the 3rd through hole is installed on case lid, in the 3rd installation through hole and the 3rd tapped hole second screw is housed.Compare with conventional construction, the utility model has increased by second screw, thereby increased the structural strength of this housing assembly, can effectively improve the sealability of casing and case lid junction plane, the machine oil that prevents oilgear overflows outside casing through casing and case lid junction plane, both guarantee the normal operation of casing internal gear, can avoid the waste of machine oil again.
Be formed with boss on the sidewall of described casing, this boss is towards the internal cavities setting of casing, and described the 3rd tapped hole is opened on this boss.Above structure can effectively strengthen structural strength of the present utility model, improves its performance.
Beneficial effect: the utility model is simple in structure, easy to make, can effectively improve the sealability of casing and case lid junction plane, the machine oil that prevents oilgear overflows outside casing through casing and case lid junction plane, has both guaranteed the normal operation of casing internal gear, can avoid the waste of machine oil again.
