The high reliability of cylinder cover.
Preferably, the side of the buffer part towards the support portion offers the abutting part of concave arc shape, the support
The transversal cross-section in portion is the circle to fit with the abutting part.
By using above-mentioned technical proposal, by the setting of abutting part, support portion is embedded in abutting part, to support portion phase
Mutual buffer limit reduces the vibration of buckling parts, improves the stability of cylinder operation.
Preferably, the inside of the support portion is hollow setting.
By using above-mentioned technical proposal, support portion is hollow setting, thus the wall thickness of support portion is relatively thin, is convenient for cooling chamber
Heat dissipation.
Preferably, four edges of the lid are provided with the first connecting hole.
By using above-mentioned technical proposal, by the setting of the first connecting hole, lid can be by installing in the first connecting hole
Bolt and cylinder block installation are fixed.
Preferably, being provided with the second connecting hole between two buckling parts and two support portions.
By using above-mentioned technical proposal, since the second connecting hole is located at the medium position of lid, thus connect by second
It connects installation bolt in hole to connect with cylinder block, further improves the leakproofness that buckling parts is connect with cylinder block.
Preferably, the buckling parts offers deformation slot far from the side of the cooling chamber.
By using above-mentioned technical proposal, by opening up for deformation slot, in cylinder operation, buckling parts vibrates, and leads to
The micro deformation for crossing deformation slot, reduces the vibration of buckling parts, improves the stability of cylinder operation.
In conclusion the utility model has the following beneficial effects:
By the setting of spare mouth, when inlet or liquid outlet block, the normal circulation of coolant liquid is affected.This
When change pipeline connection, using spare mouth as inlet or liquid outlet, thus in the case where may be implemented in and being changed without cylinder cover, after
Continuous normal use cylinder, greatly improves the reliability of cylinder cover, reduces the maintenance cost of cylinder cover.
