Abstract
The utility model relates to a strong magnetic swinging indicating needle type engine oil indicator. A contact head is fixedly installed at the lower end of a guide rod, a spring and a positioning ring are sheathed on the guide rod in sequence, and a magnetic column is inlaid at the top end of the guide rod. The upper end of the guide rod is inserted into a swinging rod hexangular seat hole together with the magnetic column and the positioning ring; the positioning ring is clamped on a lug boss in the hole; a red head indicating needle is installed in a meter needle groove of a meter disk on the upper part of a swinging rod hexangular seat; the tail end of the red head indicating needle is connected with the meter disk; a magnetic sheet is arranged in a groove of the red head indicating needle; scales are arranged on the meter disk. The utility model has the advantages of simple structure, high durability, flexible up and down swing of the red head indicating needle, and strong visibility, and the scales are arranged on the meter disk, so that the conditions of oil quantity and oil pressure can be known accurately.
Description
The utility model relates to a kind of machine oil indicator, is meant that especially a kind of strong magnetic waves indication pin type machine oil indicator.
The small tractor that China uses, the machine oil indicator adopts non-enclosed reddish tone to show that so some greasy dirts and foul enter in the indicator cap, the time one is of a specified duration, does not promptly see Chu, so indicator does not have due effect.
The principle that adopts the twin columns magnet same sex to repel each other can not demonstrate the size of pressure fuel pump again accurately, few function more than the oil mass, and reason has three:
One, when contact rises, the magnetic post is under the principle of magnetic, and another magnetic post rises, and the reaction that the situation of pressure size can not be strictly according to the facts also has so phenomenon during decline.
Two, show on that the magnetic post can accurately not rest on middle optional position.
Shortcoming such as three, sliding scale is little.
The purpose of this utility model is to provide a kind of magnetic sheet on the reddish tone pointer and magnetic material principle of opposite sex attraction of magnetic post of adopting, along with moving of magnetic post, the reddish tone pointer can swing up and down in the indicator groove thereupon, and can rest on the locational strong magnetic of the corresponding scale of dial plate and wave indication pin type machine oil indicator according to the size of pressure fuel pump.
The purpose of this utility model realizes like this, it is made up of contact (1), guide rod (2), spring (3), locating ring (4), rocking bar hexagonal seat (5), magnetic post (6), magnetic sheet (7), reddish tone pointer (8), guide rod (2) lower end installs a contact (1), pocketed springs (3), locating ring (4) successively on the guide rod (2), its top insert one magnetic post (6); The guide rod upper end is inserted in rocking bar hexagonal seat (5) hole together with magnetic post (6) and locating ring (4), locating ring (4) is stuck on the inner convex platform of hole, the horizontal dial plate (5 1) of rocking bar hexagonal seat (5) top one side and guide pillar (52) are one, be provided with an indicator groove along the vertical center section of dial plate (51), it is two-layer that dial plate (51) is divided into front and back, reddish tone pointer (8) is loaded in the groove, its tail end links to each other with dial plate (51) by riveted locating shaft (9), reddish tone pointer (8) can be teetered in the indicator groove around riveted locating shaft (9), in reddish tone pointer (8) groove magnetic sheet (7) is housed, dial plate (51) back layer one end is provided with indicating graduation.
Rocking bar hexagonal seat (5) is made for aluminium alloy, and its lower end is shaped on external thread (53);
Locating ring (4) is made for plastics; Guide rod (2) is made for aluminium alloy; Magnetic post (6) and magnetic sheet (7) are to make with permanent magnetic material.The reddish tone pointer is made display, and its top outside surface colored red is clear eye-catching.
The utility model has the advantages that:
1. simple in structure, durability is strong.
2. owing on the dial plate on rocking bar hexagonal seat top the number of degrees are arranged, can understand oil mass and oil pressure situation accurately.
3. the reddish tone pointer swings up and down flexibly, and intuitive is strong.
4. because magnetic sheet is packed in the groove of reddish tone pointer, so can stand bigger vibrations, difficult drop-off.
5. the riveted locating shaft adopts aluminium alloy to make, so be difficult for oxidation and bonding.
In conjunction with the accompanying drawings and embodiments the utility model is described further:
Fig. 1 waves indication pin type machine oil indicator structure synoptic diagram for strong magnetic
Fig. 2 is Fig. 1 vertical view
The described strong magnetic of present embodiment waves in the indication pin type machine oil indicator, and guide rod (2) lower end installs a contact (1), pocketed springs (3), locating ring (4) successively on the guide rod (2), its top insert one magnetic post (6); The guide rod upper end is inserted in rocking bar hexagonal seat (5) hole together with magnetic post (6) and locating ring (4), locating ring (4) is stuck on the inner convex platform of hole, the horizontal dial plate (51) of rocking bar hexagonal seat (5) top one side and guide pillar (5 2) are one, be provided with an indicator groove along the vertical center section of dial plate (51), it is two-layer that dial plate (51) is divided into front and back, reddish tone pointer (8) is loaded in the groove, its tail end links to each other with dial plate (51) by riveted locating shaft (9), reddish tone pointer (8) can be teetered in the indicator groove around riveted locating shaft (9), in reddish tone pointer (8) groove magnetic sheet (7) is housed, dial plate (51) back layer one end is provided with indicating graduation.
Rocking bar hexagonal seat (5) is made for aluminium alloy, and its lower end is shaped on external thread (53); Locating ring (4) is made for plastics; Guide rod (2) is made for aluminium alloy; Magnetic post (6) and magnetic sheet (7) are to make with Nd-Fe-Bo permanent magnet material.The reddish tone pointer is made display, and its top outside surface colored red is clear eye-catching.
Principle of work is as follows: strong magnetic waves indication pin type machine oil indicator and covers by the head that rocking bar hexagonal seat (5) lower end external thread (53) is screwed in small tractor, machine oil enters in the head lid oil duct by oil supply hole, arrive contact (1) bottom, machine oil makes contact (1) under the pressure of lubricating oil pump, guide rod (2) and the magnetic post (6) that is set on the guide rod (2) rise together, make positioning and guiding by locating ring (4), because the principle of opposite sex attraction of magnetic material, make reddish tone pointer (8) rise to the relevant position along riveted locating shaft (9) swing simultaneously in the indicator groove, reddish tone pointer (8) present position can clearly show on dial scale, hot head pointer (8) is put when the scale of dial plate (51) upper end, for pressure fuel pump normal.When pressure fuel pump is not enough, then contact (1), guide rod (2) and the magnetic post (6) that is set on the guide rod (2) descend together, reddish tone pointer (8) also thereupon swing drop to the relevant position, the size of pressure fuel pump can be found out in the corresponding scale position that reddish tone pointer (8) is stopped on dial plate (51).When machine oil indicator during at inoperative, because the effect of spring (3), each parts sets back.
