Model utility content
The purpose of this utility model is to provide one can avoid that oil sprayer marginal position leaks air, oil leakage phenomenon, ensures that motor normally uses, reasonable in design, machining accuracy is high, the New-type fuel injector stationary platen that is in place.
In order to solve the problem existing for background technique, the utility model is by the following technical solutions: New-type fuel injector stationary platen, comprise pressing plate body, described pressing plate body forging is one-body molded, described pressing plate body comprises compressed part, intermediate portion and clamping part successively, and the lower surface of described compressed part is provided with the first arc convex; Described intermediate portion is provided with the through hole for construction bolt, and the upper end-hole of described through hole is outward extended with inverted cone groove; The bayonet socket that described clamping part comprises Liang Ge pressing plate branch and surrounded by described Liang Ge pressing plate branch and intermediate portion, the U-shaped shape of described bayonet socket, the lower surface of described pressing plate branch is provided with the second arc convex.
Further, the width of described bayonet socket and the equal diameters of oil sprayer pressure mouth.
Further, the inwall of described through hole is provided with the screw thread matched with described bolt.
Further, the tapering of described inverted cone groove is 120 degree.
Further, the center of the described center of the first arc convex, the center of through hole and bayonet socket on the same axis.
The utility model has following beneficial effect: New-type fuel injector stationary platen described in the utility model, comprise pressing plate body, described pressing plate body forging is one-body molded, described pressing plate body comprises compressed part, intermediate portion and clamping part successively, and the lower surface of described compressed part is provided with the first arc convex; Described intermediate portion is provided with the through hole for construction bolt, and the upper end-hole of described through hole is outward extended with inverted cone groove; The bayonet socket that described clamping part comprises Liang Ge pressing plate branch and surrounded by described Liang Ge pressing plate branch and intermediate portion, the U-shaped shape of described bayonet socket, the lower surface of described pressing plate branch is provided with the second arc convex.The utility model adopts said structure, first the pressure mouth of oil sprayer is tightly clamped by the clamping part of pressing plate body, secondly the through hole of firm bolt-through intermediate portion and cylinder cap is adopted closely to fix, the first arc convex of compressed part lower surface and the screw of cylinder cap upper cap nut is finally adopted to closely cooperate, thus this injector plate can be in place with oil sprayer, namely the contact position between injector plate injector plate and cylinder cap and oil sprayer is made to reach perfect condition, tradition is avoided to occur bad connection, or compress excessively or can not compacting phenomenon, and oil sprayer marginal position can be avoided in actual use to leak air, oil leakage phenomenon, ensure that motor normally uses, thus effectively improve reliability and the fuel efficiency of motor.In addition, this oil sprayer stationary platen is reasonable in design, machining accuracy is high, low cost of manufacture, is easy to promote and use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view of Fig. 1.
Embodiment
With reference to Fig. 1, Fig. 2, this embodiment is by the following technical solutions: New-type fuel injector stationary platen, comprise pressing plate body 1, described pressing plate body 1 forges one-body molded, wherein, this pressing plate body 1 can adopt Hardened And Tempered Steel to make, such its intensity of further raising and hardness, thus meets actual use needs, described pressing plate body 1 comprises compressed part 2, intermediate portion 3 and clamping part 4 successively, the lower surface of described compressed part 2 is provided with the first arc convex 2-1, in the present embodiment, this first arc convex 2-1 is specifically to add its required precision in man-hour very high, the screw being convenient to the nut that can be in contact with it like this matches, first arc convex 2-1 just in time drops in the screw of nut when mounted, thus pressing plate can be made to contact with the position of oil sprayer reach desirable state, described intermediate portion 3 is provided with the through hole 3-1 for construction bolt, the upper end-hole of described through hole 3-1 is outward extended with inverted cone groove 3-1-1, in the present embodiment, the inwall of described through hole 3-1 is provided with the screw thread matched with described bolt, the object of such design is, when installing pressing plate, is connected after the above-mentioned through hole 3-1 of firm bolt-through with cylinder cap, and adopting the inner thread of through hole 3-1 and firm bolt closely to screw, such guarantee pressing plate and oil sprayer are in place, in addition, the tapering of above-mentioned inverted cone groove 3-1-1 is 120 degree, spacer for bolt can be placed in above-mentioned inverted cone groove 3-1-1 like this, improves the tightness of bolt further, described clamping part 4 comprises Liang Ge pressing plate branch 4-1, and the bayonet socket 4-2 to be surrounded by described Liang Ge pressing plate branch 4-1 and intermediate portion 3, the U-shaped shape of described bayonet socket 4-2, the lower surface of described pressing plate branch 4-1 is provided with the second arc convex 4-1-1, wherein, the width of described bayonet socket 4-2 and the equal diameters of oil sprayer pressure mouth, in the present embodiment, the object of such design is, the bayonet socket 4-2 of U-shaped shape is adopted to be convenient to and oil sprayer pressure mouth held tight, adopt the second arc convex 4-1-1 can increase the area of contact of pressing plate branch 4-1 and oil sprayer pressure mouth further simultaneously, and then it is stable that pressing plate branch 4-1 and oil sprayer pressure mouth can be made to clamp, firmly.
