Abstract
The utility model provides a conic lock type engine oil pressure indicator which is suitable for single-cylinder diesel engines and is mainly composed of a hood cap, an indicating rod, a connecting head, a pressure spring, a positioning guide sleeve, a conic valve rod, and a conic sealing ring. The reverse T-shaped rod part of the conic valve rod is in a frustum shape, the end is provided with a sealing ring corresponding to a sealing groove on the bottom of the conic sealing ring, and the rod part of the conic valve rod is sheathed in an inner hole of the positioning guide sleeve and a conic hole of the conic sealing ring. The utility model with a more reasonable structure fully utilizes the conic contact surfaces between each component, and the contact surfaces are sealed through engine oil pressure, so that the phenomena of oil leakage and oil seepage are eliminated thoroughly, and the normal view of the indicator is guaranteed.
Description
The utility model relates to employed awl locking-type engine oil pressure indicator on a kind of diesel engine part, particularly single cylinder diesel.
At present, employed engine oil pressure indicator in the single cylinder diesel mainly is made up of cover cap, indicating arm, joint, stage clip and piston usually, adopts the socket mode to connect between each parts, and relies on rubber washer to seal.Though it is simple in structure, easy to use, its leak resistance is relatively poor, and according to statistics, in actual use, oil spill rate reaches 75%.For this reason, people have done many improvement to it, though its performance increase, or be exactly complex structure, cost height, use inconvenience; Be exactly that leakage of oil and oil impregnate problem end can be solved.
The purpose of this utility model is to provide a kind of awl locking-type engine oil pressure indicator that single cylinder diesel uses that is suitable for, and it is rational in infrastructure, can thoroughly prevent leakage of oil and oil impregnate phenomenon, guarantees that indicator normally shows, has overcome the deficiency of existing indicator.
Technical solution of the present utility model is: it mainly is made up of cover cap, indicating arm, joint, stage clip, positioning and guiding cover, taper valve rod and conical seal ring, indicating arm is loaded in the cover cap, the through hole of its upper end extended cover crown portion is equipped with stage clip between the flange of top of covering the cap inner chamber and indicating arm end; Be provided with positioning and guiding cover and conical seal ring in the bottom of indicating arm; The middle part that is the cone table shape conical seal ring is provided with the cone shape hole of inversed taper platform shape, and its bottom is provided with seal groove; The bar portion that is inverted T-shaped is a cone table shape, end is provided with and the taper valve rod of the corresponding seal ring of conical seal ring bottom seal groove, and its bar portion is placed in the cone shape hole of the endoporus of positioning and guiding cover and conical seal ring; The bottom of conical seal ring places on the boss of joint inner chamber periphery.
The utility model structure is more reasonable, and it makes full use of the conical contact face between each parts, by engine oil pressure, makes surface of contact realize sealing, thereby thoroughly stops leakage of oil and oil impregnate phenomenon, guarantees that indicator normally shows, has overcome the deficiency of existing indicator.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Below in conjunction with accompanying drawing the utility model and embodiment are described in further detail:
The utility model mainly is made up of cover cap 2, indicating arm 1, joint 4, stage clip 3, positioning and guiding cover 5, taper valve rod 9 and conical seal ring 6, and indicating arm 1 is loaded in the cover cap 2, and the through hole at its extended cover cap 2 tops, upper end is in order to show engine oil pressure; Between the flange of top of covering cap 2 inner chambers and indicating arm 1 end, be equipped with stage clip 3; Be provided with positioning and guiding cover 5 and conical seal ring 6 successively in the bottom of indicating arm 1; The end flange of positioning and guiding cover 5 is interposed between the top of cover cap 2 bottoms and conical seal ring 6.The middle part that is cone table shape conical seal ring 6 is provided with the cone shape hole 7 of inversed taper platform shape, and its bottom is provided with seal groove 8; The bar portion that is inverted T-shaped is a cone table shape, the bottom is provided with and the taper valve rod 9 of conical seal ring 6 bottom seal grooves 8 corresponding seal rings 10, and its bar portion is placed in the cone shape hole 7 of the endoporus of positioning and guiding cover 5 and conical seal ring 6; The bottom of conical seal ring 6 places on the boss of joint 4 inner chamber peripheries, and locatees.
During use, at first the utility model is loaded on the diesel engine.When diesel engine was worked, machine oil entered its inner chamber by the oil inlet hole on the joint 4 11, and the resistance that overcomes stage clip 3 makes taper valve rod 9 up, and taper valve rod 9 withstands the bottom of indicating arm 1, and the upper end of indicating arm 1 is stretched out outside the through hole of cover cap 2, shows engine oil pressure; At this moment, the lip of the cone shape hole 7 of the inversed taper platform shape at conical seal ring 6 middle parts pushes mutually with the valve rod of the cone table shape of taper valve rod 9, produces coupling mechanism force and seals; When engine oil pressure increases, taper valve rod 9 progressively rises, diameter corresponding to taper valve rod 9 places of the lip of the cone shape hole 7 at conical seal ring 6 middle parts also increases thereupon, to the also corresponding increase of tension force of the lip of the cone shape hole 7 of conical seal ring 6, so coupling mechanism force is also big more; In addition, when machine oil reaches certain pressure, taper valve rod 9 rises to top dead center, at this moment, the seal ring 10 of being located at taper valve rod 9 ends snaps in the seal groove 8 of conical seal ring 6 bottoms, under the pressure effect of machine oil, and closely pressing, increase the reliability of sealing again, thereby thoroughly stopped oil seepage phenomena.When diesel engine quits work when being inorganic oil pressure, indicating arm 1 is owing to be subjected to the effect of stage clip 3, and descending, resets, and reaches lower dead center.
