Abstract
The utility model discloses a single-layer board metal head gasket. The head gasket comprises a transverse straight L-shaped gasket body, two rectangular openings at intervals are formed in a vertical section of the L-shaped gasket body, side fixing lugs with installation holes are distributed on the peripheries of the rectangular openings, a long-strip-shaped interstitial hole is formed between the vertical section and a transverse straight section of the L-shaped gasket body, cylinder holes are distributed in the transverse straight section of the L-shaped gasket body, a seal rubber rib is arranged on the outer edge of each cylinder hole, installation holes are distributed in the peripheries of the cylinder holes, kidney-shaped positioning holes are distributed in the outer circles of the installation holes, water holes are distributed in the outer sides of the kidney-shaped positioning holes, and the two side faces of the transverse straight section of the L-shaped gasket body are provided with a groove and an arc boss which are distributed at intervals. The single-layer board metal head gasket is convenient to disassemble, the stress area is increased without increasing the contact area, so that pressing force in the installation process is large, seal performance of the single-layer board metal head gasket is ensured, and the head gasket is good in stability.
Description
Technical field
The utility model relates to cylinder seal technical field, relates in particular to a kind of single-layer plate metal air cylinder gasket.
Background technique
Head gasket on existing installation motor often affects the normal work of motor because its potted line is poor, head gasket is arranged in the gap between engine cylinder cap and cylinder body, mainly play cylinder leakage tester, the effect of leaking of preventing, and the quality of head gasket, directly have influence on the working life of motor, and the replacement cost of maintenance and head gasket.
Model utility content
The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of single-layer plate metal air cylinder gasket is provided.
The utility model is achieved through the following technical solutions:
A kind of single-layer plate metal air cylinder gasket, it is characterized in that: include l shaped gasket body anyhow, vertical section of oblong openings that is provided with two intervals of described l shaped gasket body, and the circumferential distribution of oblong openings has with the fixing ear of the side of mounting hole, vertical section of described l shaped gasket body and anyhow between section, be provided with long strip mesopore, described l shaped gasket body anyhow section on be distributed with cylinder-bore, the outer edge of described cylinder-bore is provided with caulking gum muscle, the circumferential distribution of described cylinder-bore has mounting hole, the outer ring of described mounting hole is distributed with kidney-shaped positioning hole, the outside of described kidney-shaped positioning hole is distributed with water hole, and the bi-side of section anyhow of l shaped gasket body are respectively equipped with groove spaced apart and arc boss.
The utility model has the advantages that:
The utility model is by the structural design of l shaped gasket body, its installation when it needs repairing and changes, dismantle more convenient, the structural design of the oblong openings on vertical section by l shaped gasket body, it has reached increase lifting surface area, and do not increase the effect of area of contact, when it is installed, impacting force is larger, the caulking gum muscle and the mounting hole that coordinate cylinder-bore, kidney-shaped positioning hole, the distribution in water hole, do not affecting under the effect in each hole, guaranteed its sealability, by the bi-side of section anyhow of l shaped gasket body groove spaced apart and the structure of arc boss, guaranteed whole l shaped gasket body stability in use.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
