The utility model discloses a kind of internal-combustion engine closed chamber.This internal-combustion engine closed chamber, comprises the forming unit of four arcs, and forming unit comprises one-body molded vertically disposed horizontal body and vertical body; Described horizontal body and vertical body outer wall connecting part are provided with annular slope, and horizontal body and vertical inner body wall connecting part are provided with curve bath; Described vertical body bottom portion offers circular groove, and horizontal body is provided with multiple through hole; Between described adjacent forming unit, gap is 1-1.5mm, and forming unit two ends are provided with groove, and groove is positioned on vertical body.The utility model structure is simple, reasonable in design, easy to operate, utilizes this elasticity to seal when assembling.When to arrange gap etc. between adjacent forming unit be to assemble, compressing can the space of preparatory compression, and arranging groove is to coordinate another position in internal-combustion engine also to have groove, improves sealability.
Description
Technical field
The utility model relates to internal combustion engine fittings technical field, especially a kind of internal-combustion engine closed chamber.
Background technique
Internal-combustion engine is a kind of dynamic power machine, and it is by making fuel burn at machine intimate, and the heat energy of being released directly is converted to the heat engine of power.Sensu lato internal-combustion engine not only comprises stroke piston combustion engine, rotary engine and free piston engine, also comprise the gas turbine of rotary vane type, jet engine etc., but usually said internal-combustion engine refers to internal-combustion piston engine.Internal-combustion piston engine is the most general with reciprocating piston type.Internal-combustion piston engine, by fuel and air mixing, burns in its cylinder combustion, and the heat energy discharged makes the combustion gas producing High Temperature High Pressure in cylinder.Combustion gas is expanded and is promoted piston work done, then mechanical work is exported by connecting rod or other mechanisms, drives follower work.Part very crucial when closed chamber is internal-combustion engine assembling, traditional closed chamber is structure as a whole, and sealing effect is poor.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of structure simple, the internal-combustion engine closed chamber of good sealing effect.
The utility model solves the technological scheme that its technical problem adopts: a kind of internal-combustion engine closed chamber, comprises the forming unit of four arcs, and forming unit comprises one-body molded vertically disposed horizontal body and vertical body; Described horizontal body and vertical body outer wall connecting part are provided with annular slope, and horizontal body and vertical inner body wall connecting part are provided with the curve bath be bent upwards; Described vertical body bottom portion offers circular groove, and horizontal body is provided with multiple through hole; Between described adjacent forming unit, gap is 1-1.5mm, and forming unit two ends are provided with slope, and groove is positioned in horizontal body.
Further, described through hole comprises large through-hole, middle through hole and small through hole, and large through-hole is evenly distributed in horizontal body, and horizontal body two ends offer middle through hole and small through hole.
Further, described middle through hole and small through hole are between two large through-holes, and middle through hole is between small through hole and large through-hole.
Further, the second annular slope is provided with bottom described horizontal body inwall.
The beneficial effects of the utility model are: the utility model structure is simple, and reasonable in design, easy to operate, comprise the forming unit of four arcs, each forming unit is 1/4th sections, possesses elasticity, utilize this elasticity to seal when assembling.When to arrange gap etc. between adjacent forming unit be to assemble, compressing can the space of preparatory compression, and arranging groove is to coordinate another position in internal-combustion engine also to have groove, improves sealability.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Internal-combustion engine closed chamber as Figure 1-5, comprises the forming unit of four arcs, and forming unit comprises one-body molded vertically disposed horizontal body 1 and vertical body 2; Horizontal body 1 and vertical body 2 outer wall connecting part are provided with annular slope 4, and horizontal body 1 and vertical body 2 inwall connecting part are provided with the curve bath 5 be bent upwards; Offer circular groove 3 bottom vertical body 2, horizontal body 1 is provided with 12 through holes; Between described adjacent forming unit, gap is 1mm, and forming unit two ends are provided with groove 9, and groove 9 is positioned in horizontal body 1.
Through hole comprises large through-hole 6, middle through hole 7 and small through hole 8, and large through-hole 6 is evenly distributed in horizontal body 1, and horizontal body 1 two ends offer middle through hole 7 and small through hole 8; Middle through hole 7 and small through hole 8 are between two large through-holes 6, and middle through hole 7 is between small through hole 8 and large through-hole 6; The second annular slope 10 is provided with bottom horizontal body 2 inwall.
This internal-combustion engine closed chamber structure is simple, and reasonable in design, easy to operate, comprise the forming unit of four arcs, each forming unit is 1/4th sections, possesses elasticity, utilizes this elasticity to seal when assembling.When to arrange gap etc. between adjacent forming unit be to assemble, compressing can the space of preparatory compression, and arranging groove is to coordinate another position in internal-combustion engine also to have groove, improves sealability.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
