Description
Technical field
Engine art is the utility model is related to, more particularly to a kind of engine fuel injector pressing plate.
Background technology
Injector plate is a parts in engine, and injector plate is bolted on engine cylinder cover
On, so as to which oil sprayer clamping is covered in engine cylinder, to prevent fuel injector from loosening.The injector plate largely used at present
Profile is excessive, and arrangement installation is inconvenient, and the hidden danger for causing gas leakage because can not compress fuel injector easily be present.With engine
The demand of profile increasingly densification, existing injector plate can not meet requirement.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form
Technology.
Utility model content
The purpose of this utility model is to provide a kind of engine fuel injector pressing plate, so as to overcome existing injector plate
Arrangement installation is inconvenient and the shortcomings that causing the hidden danger of gas leakage because can not compress fuel injector easily be present.
To achieve the above object, the utility model provides a kind of engine fuel injector pressing plate, wherein, including：Pressing plate body,
The rear end of its bottom surface is convexly equipped with one first supporting surface；U-shaped bayonet socket, it is arranged at the front end of the pressing plate body, and the U-shaped bayonet socket
It is open towards front；The bottom surface of two side walls of the U-shaped bayonet socket is the second supporting surface；Second supporting surface protrudes from the pressure
The bottom surface of plate body；And through hole, it is arranged at the middle part of the pressing plate body, and the upper end of the through hole be provided with one be used for it is spherical
The chamfering that packing ring is coordinated.
Preferably, in above-mentioned technical proposal, first supporting surface is sphere.
Preferably, in above-mentioned technical proposal, second supporting surface is arc surface.
Compared with prior art, the utility model has the advantages that：
Compact appearance of the present utility model, simple in construction, arrangement installation is easy, and its first supporting surface is pressed in engine cylinder cover
Upper and the second supporting surface is pressed on the clamping face of fuel injector, then is coordinated by the chamfering of through hole with spherical washer to ensure bolt
The caused diameter parallel for compressing force direction and fuel injector, so as to reduce the hidden danger for causing gas leakage because not pressing tightly fuel injector.

Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
Fig. 1 to Fig. 2 shows a kind of structure of engine fuel injector pressing plate according to the utility model preferred embodiment
Schematic diagram, the engine fuel injector pressing plate include pressing plate body 1, U-shaped bayonet socket 4 and through hole 6, with reference to figure 1 and Fig. 2, pressing plate body 1
The rear end of bottom surface 2 is convexly equipped with one first supporting surface 3, and the first supporting surface 3 covers for being pressed on engine cylinder.Preferably, first
Supporting surface 3 is sphere.U-shaped bayonet socket 4 is arranged at the front end of pressing plate body 1, and the opening of U-shaped bayonet socket 4 is towards front, U-shaped bayonet socket 4
The bottom surface of two side walls is the second supporting surface 5, and the second supporting surface 5 protrudes from the bottom surface of pressing plate body 1.U-shaped bayonet socket 4 is used to stick spray
Oily device, and be pressed on by the second supporting surface 5 on the clamping face of fuel injector.Preferably, the second supporting surface 5 is arc surface.Through hole 6 is set
The middle part of pressing plate body 1 is placed in, and the upper end of through hole 6 is provided with a chamfering 7 for being used to be coordinated with spherical washer 8.Bolt is worn
Cross the cylinder head after through hole 6 with engine to be attached, covered so that pressing plate body 1 is pressed on cylinder.
Compact appearance of the present utility model, simple in construction, arrangement installation is easy, during installation, the first supporting surface of pressing plate body 1
3 be pressed in engine cylinder cover and U-shaped bayonet socket 4 be stuck in fuel injector after be pressed in by the second supporting surface 5 on the clamping face of fuel injector, then by
The chamfering 7 of through hole 6 is coordinated with spherical washer 7 to ensure that the axis that force direction and fuel injector are compressed caused by bolt 9 is put down
OK, the hidden danger of gas leakage is caused because not pressing tightly fuel injector so as to reduce.
The foregoing description to specific illustrative embodiment of the present utility model is to illustrate and the purpose of illustration.These
Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
