Abstract
The utility model relates to a screw-plug type transparent oil pointer, which comprises an oil pointer base body and a transparent window and is characterized in that the oil pointer base body is a hollow screw plug with an external thread, wherein one end of the hollow screw plug is provided with a hollow screw cap, an annular groove is formed in the hollow screw cap, a light-reflecting background panel is embedded into the annular groove, the transparent window is fixedly arranged at the end part of the hollow screw cap, the transparent window is parallel to the light-reflecting background panel, the center of the light-reflecting background panel is at least marked with an annular scale mark, at least four arch-shaped holes are uniformly distributed in the periphery of the annular scale mark, and the arch apex of each arch-shaped hole is tangent to the annular scale mark.
Description
Technical field
The utility model relates to oil ga(u)ge, especially a kind of transparent oil ga(u)ge of plug screw formula that has reflective background board and scale.
Background technique
In the gear-box of rail traffic vehicles, the oil level inspection is basic, and oil measurement rod need disassemble inspection from gear-box through oil measurement rod or long tube formula oil ga(u)ge, and the lubricant oil in the gear-box is contaminated easily.The input of long tube formula oil ga(u)ge does not need dismounting in using, because long tube formula oil ga(u)ge generally adopts plexiglass or transparent plastic, and is installed in the gearbox wall outside; When rail traffic vehicles moves; Not only the appearance of gear-box can receive sand grains and the impact of other foreign object in the environment, is easy to oil impregnate, in case oil impregnate occurs also very easily by the fluid of seepage and dust pollution; Cause showing unintelligible, influence is observed.
The model utility content
The purpose of the utility model is: the use inconvenience to oil measurement rod that uses in the current track vehicular traffic gear-box or the existence of long tube formula oil ga(u)ge maybe can not be resisted impact; Practical problems such as the oil level demonstration is unintelligible, can not accurately judge provide a kind of plug screw formula transparent oil ga(u)ge.
The purpose of the utility model is achieved in that the transparent oil ga(u)ge of a kind of plug screw formula, comprises oil ga(u)ge matrix and transparent window, it is characterized in that: the oil ga(u)ge matrix is for being with externally threaded hollow cock; Hollow cock one end is provided with hollow nut; Be provided with annular groove in the hollow nut, be embedded with reflective background board in the annular groove, the end of hollow nut is embedded with transparent window; Transparent window is parallel with reflective background board; Described reflective background board center has indicated a circular scale line at least, and circular scale line periphery is evenly distributed with four arch holes at least, and the vault in arch hole and circular scale line are tangent.
In the utility model: the hollow nut that is located at hollow cock is the hollow nut of square, or the hollow nut of regular hexagon; Described transparent window is a toughened glass; Described reflective background board is a corrosion resistant plate.
In the utility model: described reflective background board center indicates has 2 ~ 3 concentric circular scale lines, and the circular scale line of the vault in arch hole and outmost turns is tangent.
In the utility model: the end of hollow nut is embedded with transparent window and is meant: at hollow nut bead limited step is set; Transparent window is placed on the described limited step; Form bound edge through the hollow nut bead of punching press, make transparent window be fixed on the end of hollow nut.
The advantage of the utility model is: because transparent window adopts toughened glass, the impact that sand grains or other foreign matters bump in the time of can resisting vehicle operating; Owing in oil ga(u)ge, be provided with the reflective background board parallel with transparent window, it is more clear that oil level is shown; Around reflective background board, establish and arrange the arch hole, can guarantee that on the one hand oil level in time gets into the observation district between reflective background board and the transparent window, can also avoid on the other hand observing the district by dirty oil pollution at oil ga(u)ge between reflective background board and the transparent window; Adopt the circular scale line to form two different signs with the lower edge, efficiently solve the defective that circular oil ga(u)ge can't identify scale in the upper edge of annular.The structure that the embedded installation of reflective background board and transparent window punching type can make oil ga(u)ge is compact more, performance is more reliable.
Description of drawings
Fig. 1 is a kind of example structure schematic representation that the utility model relates to.
Fig. 2 be Fig. 1 prolong A to front view.
Among the figure: 1, oil ga(u)ge cock, 2, peep hole, 3, bound edge, 4, annular groove, 5, reflective background board, 6, transparent window, 7, the circular scale line, 8, the arch hole.
Embodiment
Accompanying drawing is nonrestrictive to disclose the structural representation of a kind of specific embodiment that the utility model relates to, and below in conjunction with accompanying drawing the utility model is done further to describe.
Visible by Fig. 1 Fig. 2; The oil ga(u)ge matrix 1 of the utility model is for being with externally threaded hollow cock, and hollow cock one end is provided with hollow nut, is provided with annular groove 4 in the hollow nut; Be embedded with reflective background board 5 in the annular groove 4; The end of hollow nut is installed with transparent window 6, and transparent window 6 is parallel with reflective background board 5, and described reflective background board 5 centers have indicated a circular scale line 7 at least; Circular scale line 7 peripheries are evenly distributed with four arch holes 8 at least, and the vault in arch hole 8 and circular scale line 7 are tangent.
In the present embodiment, the hollow nut that is located at hollow cock is the hollow nut of regular hexagon; Described transparent window 6 is a toughened glass; Described reflective background board 5 is a corrosion resistant plate.Described reflective background board 5 centers indicate has 2 concentric circular scale lines 7, and the circular scale line 6 of the vault in arch hole 7 and outmost turns is tangent.At hollow nut bead limited step is set, transparent window 6 is placed on the described limited step, form bound edge 3, make transparent window 6 be fixed on the end of hollow nut through the hollow nut bead of punching press.
During practical implementation, the hollow nut that is located at hollow cock also can adopt the hollow nut of square, and described reflective background board 5 centers indicate and also can be provided with 1 or 3 concentric circular scale lines 7 are set.
The utility model is that the screw thread in the oil ga(u)ge cock 1 is installed in the oil ga(u)ge mounting hole of gear-box during use.During the vehicle regular maintenance, can see the oil level in the oil ga(u)ge below gear-box very directly, clearly.
