Description
Technical field
The present invention relates to engine fittings technical field, especially relate to a kind of self-regulating engine piston mechanism.
Background technique
Conventionally,, after the piston of motor is connected with connecting rod, piston is positioned at cylinder, connecting rod is exported for power.But, cylinder wall enough straight and smooth and piston have as far as possible enough height with ensure piston can with good being sealed and matched of cylinder.So, if the quality of cylinder wall and piston is slightly poor, very easily there is the situation of poor fit, and be easy to occur the situation of seizure of piston.
Summary of the invention
The object of this invention is to provide a kind of self-regulating engine piston mechanism, it has the excellent sealing that is easy to ensure piston and cylinder, and piston is difficult for stuck feature.
The technical solution adopted in the present invention is: self-regulating engine piston mechanism, and described self-regulating engine piston mechanism comprises:
---upper piston, this upper piston is cylindrical, and this upper piston bottom is provided with the first ball head nest, on this first ball head nest, is fixed with the first cover plate by screw;
---lower piston, this lower piston is cylindrical, and the top of this lower piston is provided with first connecting rod, bottom prepared by upwardly extending rigid material and is provided with the second ball head nest, wherein, the upper end of this first connecting rod is provided with the first bulb, on this second ball head nest, is fixed with the second cover plate by screw;
---second connecting rod, this second connecting rod upper end has the second bulb, lower end has attachment hole; And
This first bulb and this first ball head nest match, this second bulb and this second ball head nest match.
The bottom of described upper piston is provided with the annular limited step of downward protrusion, and this limited step is around this first ball head nest setting, and the lower end surface of this limited step is 1 ~ 3mm apart from the spacing of the upper surface of this lower piston.
The advantage that compared to the prior art the present invention had is: be easy to ensure the excellent sealing of piston and cylinder, and piston is difficult for stuck.Self-regulating engine piston of the present invention mechanism adopts mode that 2 pistons (being upper piston and lower piston) are connected to substitute a piston of original technology, and the height of each piston is without higher, thereby makes cylinder wall without having high flatness.Meanwhile, adopt between the piston that bulb mode connects and between piston and connecting rod, all there is enough mobilities of 360 °, having reduced the probability of seizure of piston.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the master of embodiments of the invention looks sectional view.
In figure: 10, upper piston, 11, the first ball head nest, 12, the first cover plate, 13, limited step; 20, lower piston, 21, first connecting rod, 211, the first bulb, 22, the second ball head nest, 23, the second cover plate; 30, second connecting rod, 31, the second bulb, 32, attachment hole.
Embodiment
Embodiment, as shown in Figure 1: self-regulating engine piston mechanism, comprising: the parts such as upper piston 10, lower piston 20, second connecting rod 30.Wherein: this upper piston 10 is cylindrical, and these upper piston 10 bottoms are provided with the first ball head nest 11, on this first ball head nest 11, are fixed with the first cover plate 12 by screw.Certainly, on this first cover plate 12, be provided with through hole corresponding to the position of this first ball head nest 11.This lower piston 20 is cylindrical, and the top of this lower piston 20 is provided with first connecting rod 21, bottom prepared by upwardly extending rigid material and is provided with the second ball head nest 22.Wherein, the upper end of this first connecting rod 21 is provided with the first bulb 211, on this second ball head nest 22, is fixed with the second cover plate 23 by screw.Equally, this second cover plate 23 is also provided with through hole corresponding to the position of this second ball head nest 22.These second connecting rod 30 upper ends have the second bulb 31, lower end has attachment hole 32.And this first bulb 211 and this first ball head nest 11 match, this second bulb 31 and this second ball head nest 22 match.What is called matches to refer to and forms bulb and connect, thus the rotation that this first connecting rod 21 can 360 ° with respect to this upper piston 10, and this second connecting rod 30 can carry out the rotation of 360 ° with respect to this lower piston 20.Like this, this self-regulating engine piston mechanism adopts the mode of 2 pistons connections to substitute a piston of original technology, and the height of each piston is without higher, and cylinder wall is without having high flatness., adopt between two pistons that bulb connects, all very flexible between lower piston and second connecting rod meanwhile, reduced the probability of seizure of piston.
Further say, the bottom of this upper piston 10 is provided with the annular limited step 13 of downward protrusion, this limited step 13 arranges around this first ball head nest 11, and under original state, the lower end surface of this limited step 13 is 1 ~ 3mm apart from the spacing of the upper surface of this lower piston 20., this space D is: 1mm≤D≤3mm.Like this, avoid this lower piston 20 to there is larger deflection with respect to this upper piston 10.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
