Abstract
The utility model discloses a kind of Novel diesel engine cylinder caps, lid including being covered on cylinder body top, lid is removably fastened and connected in cylinder body, lid is equipped with reinforcement patches and cushion towards the side of cylinder body, reinforcement patches are fixedly arranged on lid, and cushion protrudes into cylinder body, interior hole axle of the cushion perpendicular to cylinder body, the diameter of cushion is less than the diameter of cylinder inner bore, and telescopic buffer is connected between cushion and reinforcement patches.The Novel diesel engine cylinder cap has many advantages, such as that convenient for disassembly and assembly, excellent in heat dissipation effect and durability are strong.The Novel diesel engine cylinder cap has the advantages that endurance can be enhanced and prolongs the service life.
Description
Technical field
The utility model relates to diesel engine manufacturing technologies, and in particular to a kind of Novel diesel engine cylinder cap.
Background technique
Cylinder cap is the core key part of engine, the component part of burning chamber of diesel engine, not only by high temperature and pressure gas
The strong effect of body, and need periodically to bear higher mechanical load and thermic load, simultaneously because bolt pretightening makes
Cylinder cover bears pressure, and acts on cylinder cap by bending with gaseous-pressure collective effect.Existing cylinder cap endurance is poor, uses the longevity
It orders short.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide one kind to enhance endurance
And the Novel diesel engine cylinder cap to prolong the service life.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of Novel diesel engine cylinder cap, the lid including being covered on cylinder body top, the dismountable fit sealing of lid
It is connected to the cylinder body, the lid is equipped with reinforcement patches and cushion towards the side of the cylinder body, and the reinforcement patches are fixedly arranged on
The lid, the cushion protrude into the cylinder body, interior hole axle of the cushion perpendicular to the cylinder body, the cushion
Diameter be less than the cylinder inner bore diameter, be connected with telescopic buffer between the cushion and the reinforcement patches.
As a further improvement of the above technical scheme:
The telescopic buffer includes sleeve, sliding pin and spring, and the sleeve is fixedly connected on the reinforcement patches, described
Sliding pin is fixedly connected on the cushion, the sliding pin sliding sleeve in the sleeve, the spring be connected to the sliding pin with it is described
Between reinforcement patches.
The reinforcement patches and the lid, the sleeve and the reinforcement patches and the sliding pin and the cushion are equal
It is integrally formed.
Compared with the prior art, the advantages of the utility model are:
The Novel diesel engine cylinder cap of the utility model, the lid including being covered on cylinder body top, lid removably fasten
It is sealedly attached to cylinder body, lid is equipped with reinforcement patches and cushion towards the side of cylinder body, and reinforcement patches are fixedly arranged on lid, and cushion is stretched
Enter in cylinder body, for cushion perpendicular to the interior hole axle of cylinder body, the diameter of cushion is less than the diameter of cylinder inner bore, cushion and reinforces
Telescopic buffer is connected between pad.The utility model diesel engine cylinder cover increases telescopic buffer, reinforcement patches and cushion, stretches
Contracting buffer unit includes sleeve, sliding pin and spring, and when lid is by under impact force, impact force damping of shocks pad first is buffered
Pad is mobile towards reinforcement patches, and squeezes spring, under the contraction of spring, greatly alleviates the impact force of reinforcement patches, simultaneously
Impact force has been isolated in lid in reinforcement patches, thereby increases the endurance of lid and extends the service life of lid.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of the utility model Novel diesel engine cylinder cap.
Fig. 2 is that Fig. 1 is enlarged structure schematic diagram at A.
Each label indicates in figure:

Specific embodiment
Below with reference to the attached drawing of the utility model, the technical solution of the utility model embodiment is described in detail, is shown
So, described embodiment is only the embodiment of the utility model a part, instead of all the embodiments, practical based on this
Novel embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, the Novel diesel engine cylinder cap of the present embodiment, the lid 2 including being covered on 1 top of cylinder body, lid
Body 2 is removably fastened and connected in cylinder body 1, and lid 2 is equipped with reinforcement patches 3 and cushion 4 towards the side of cylinder body 1, reinforces
Pad 3 is fixedly arranged on lid 2, and cushion 4 protrudes into cylinder body 1, and for cushion 4 perpendicular to the interior hole axle of cylinder body 1, the diameter of cushion 4 is small
Telescopic buffer 5 is connected between the diameter of 1 inner hole of cylinder body, cushion 4 and reinforcement patches 3.
In the present embodiment, telescopic buffer 5 includes sleeve 51, sliding pin 52 and spring 53, and sleeve 51, which is fixedly connected on, to be added
Gu pad 3, sliding pin 52 is fixedly connected on cushion 4, and 52 sliding sleeve of sliding pin is connected to sliding pin 52 and reinforcement patches 3 in sleeve 51, spring 53
Between.
In the present embodiment, reinforcement patches 3 and lid 2, sleeve 51 and reinforcement patches 3 and sliding pin 52 and cushion 4 one at
Type.
The utility model diesel engine cylinder cover increases telescopic buffer 5, reinforcement patches 3 and cushion 4, and telescopic buffer 5 wraps
Include sleeve 51, sliding pin 52 and spring 53, when lid 2 is by under impact force, impact force damping of shocks pad 4 first, cushion 4 to
Reinforcement patches 3 it is mobile, and squeeze spring 53, under the contraction of spring 53, greatly alleviate the impact force of reinforcement patches 3, together
When reinforcement patches 3 impact force has been isolated in lid 2, thereby increase the endurance of lid 2 and extend the service life of lid 2.
