Abstract
The utility model relates to a total closed magnetic ring type lubrication oil indicator whose structure is that the lower end of a guide rod is fixedly provided with a contact terminal; the guide rod is orderly sheathed with a spring and a positioning ring; a retainer ring is adhered on the upper end of the guide rod, and the top end of the guide rod is enchased with a magnetic post; the upper end of the guide rod, the magnetic post, the retainer ring and the positioning ring are inserted the hexagonal seat hole of a guide post; the positioning ring is clamped on the lug boss in the hole; the magnetic ring is sheathed on the guide post of the upper part of the hexagonal seat of the guide post; a transparent indicating cap is screwed with the hexagonal seat of the guide post. The utility model has the advantages of simple structure, high durability, completely reliable enclosing performance, flexible movement of the magnetic ring from top to bottom and strong direct viewing; the utility model can stay a corresponding position according to the magnitude of the pressure of oil pumps.
Description
The utility model relates to a kind of machine oil indicator, is meant a kind of totally-enclosed magnet ring type machine oil indicator especially.
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 employing magnet ring and magnetic post principle of opposite sex attraction, and along with moving of magnetic post, magnet ring can slide up and down along guide pillar thereupon, and can rest on the totally-enclosed magnet ring type machine oil indicator of relevant position 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), guide pillar hexagonal seat (4), locating ring (5), magnet ring (6), magnetic post (7), transparent indication cap (8), back-up ring (9), guide rod (2) lower end installs a contact (1), pocketed springs (3), locating ring (5), back-up ring (9) successively on the guide rod (2), back-up ring (9) is bonded in guide rod upper end, its top insert one magnetic post (7); The guide rod upper end is inserted in guide pillar hexagonal seat (4) hole together with magnetic post (7), back-up ring (9) and locating ring (5), locating ring (5) is stuck on the inner convex platform of hole, magnet ring (6) is sleeved on the guide pillar (41) on guide pillar hexagonal seat (4) top, be slidingly matched, transparent indication cap (8) is threaded with guide pillar hexagonal seat (4) pedestal.Be bonded in back-up ring (9) on the guide rod (2) and can prevent that contact from partly deviating from.
Guide pillar hexagonal seat (4) is made for engineering plastics, and its lower end is shaped on external thread (42); Transparent indication cap (8) is made for transparent plastic; Guide rod (2) is made for mild carbon steel; Magnet ring (6) is to make with permanent magnetic material with magnetic post (7).Magnet ring is made display, and the outside surface colored red is clear eye-catching.
The utility model has the advantages that:
1. closed performance is reliable fully, and greasy dirt and foul can not enter in the indication cap.
2. magnet ring slides up and down flexibly, and intuitive is strong.
3. rational in infrastructure, aesthetic in appearance, durable in use.
4. the magnet ring display is in that big I rests on the corresponding position according to pressure fuel pump on the guide pillar.
5. magnet ring slides up and down apart from bigger, can be at 0～25mm.
6. do not reach vertex position as the magnet ring display, when descending 5～6mm from the summit (working position), fault has partly taken place just prove lubricating oil pump.
1. pressure fuel pump deficiency;
2. oil mass is not enough;
3. oil circuit blocks.
In conjunction with the accompanying drawings and embodiments the utility model is described further:
Fig. 1 is totally-enclosed magnet ring type machine oil indicator structure synoptic diagram
Fig. 2 is totally-enclosed magnet ring type machine oil indicator operate as normal structural representation
Fig. 3 for totally-enclosed magnet ring type machine oil indicator non-normal working structural representation wherein: arrow is depicted as the trend of machine oil among Fig. 2, Fig. 3
In the described totally-enclosed magnet ring type machine oil indicator of present embodiment, guide rod (2) lower end installs a contact (1), pocketed springs (3), locating ring (5), back-up ring (9) successively on the guide rod (2), back-up ring (9) are bonded in guide rod upper end, its top insert one magnetic post (7); The guide rod upper end is inserted in guide pillar hexagonal seat (4) hole together with magnetic post (7), back-up ring (9) and locating ring (5), locating ring (5) is stuck on the inner convex platform of hole, magnet ring (6) is sleeved on the guide pillar (41) on guide pillar hexagonal seat (4) top, be slidingly matched, transparent indication cap (8) is threaded with guide pillar hexagonal seat (4) pedestal.
Guide pillar hexagonal seat (4) is made for engineering plastics, and its lower end is shaped on external thread (42); Transparent indication cap (8) is made for transparent plastic; Guide rod (2) is made for mild carbon steel; Magnet ring (6) is to make with Nd-Fe-Bo permanent magnet material with magnetic post (7), and magnet ring is made display, and the outside surface colored red is clear eye-catching.
Principle of work is as follows: totally-enclosed magnet ring type machine oil indicator is screwed on the head lid (10) of small tractor by guide pillar hexagonal seat (4) lower end external thread (42), machine oil enters in the head lid oil duct by oil supply hole (11), arrive contact (1) bottom, machine oil makes contact (1) under the pressure of lubricating oil pump, guide rod (2) and the magnetic post (7) that is set on the guide rod (2) rise together, make positioning and guiding by locating ring (3), because magnet principle of opposite sex attraction, make magnet ring (6) rise to the relevant position simultaneously along guide pillar (41), magnet ring (6) present position can clearly in transparent indication cap (8) be found out, when magnet ring (6) is positioned at guide pillar (41) top, for pressure fuel pump is normal, as shown in Figure 2.When pressure fuel pump is not enough, then contact (1), guide rod (2) and the magnetic post (7) that is set on the guide rod (2) descend together, magnet ring (6) also drops to the relevant position thereupon, the corresponding position that magnet ring (6) is stopped on guide pillar (41), can find out the size of pressure fuel pump, when magnet ring (6) when vertex position descends 5～6mm, prove that just fault has partly taken place oil pump, as shown in Figure 3.When machine oil indicator during at inoperative, because the effect of spring (3), each parts returns to position as shown in Figure 1.
