Abstract
The utility model relates to a display rod 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 hexagonal screw thread seat hole together with the magnetic column and the positioning ring; the positioning ring is clamped on a rug boss in the hole; a display rod is installed in a guiding cap; the upper part of the display rod penetrates out of a central hole on the top end of the guiding cap; the lower part of the guiding cap is connected with a screw thread on the upper part of a hexagonal screw thread seat. The utility model has the advantages of simple structure, high durability, easy fabrication, low cost, flexible up and down sliding motion of the display rod, and strong visibility. Besides, the utility model can stay at a relevant position according to the intensity of the pressure of oil pumps.
Description
The utility model relates to a kind of machine oil indicator, is meant a kind of demonstration rod-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 purpose of this utility model is to provide a kind of magnetic sheet and magnetic post principle of same-sex repulsion that adopts in the display pole, along with moving of magnetic post, display pole can move up and down in leading cap thereupon, and can expose according to display pole and lead outer what of cap, determine few demonstration rod-type machine oil indicator more than the size of pressure fuel pump and the oil mass.
The purpose of this utility model realizes like this, it by contact (1), guide rod (2), spring (3), hexagonal threaded block (4), positioning ring (5), magnetic post (6), magnetic sheet (7), lead cap (8), display pole (9) is formed, guide rod (2) lower end installs a contact (1), pocketed springs (3), positioning ring (5) successively on the guide rod (2), its top insert one magnetic post (6); The guide rod upper end is inserted in hexagonal threaded block (4) hole together with magnetic post (6) and positioning ring (5), positioning ring (5) is stuck on the inner convex platform of hole, display pole (9) is loaded on leads in the cap (8), its top passes the center hole of leading cap (8) top, be slidingly matched, a magnetic sheet (7) is equipped with in its underpart, and display pole (9) floats over leads in the cap (8), top can move up and down along center hole, leads cap (8) bottom and is threaded with hexagonal threaded block (4) top.
Display pole (9) top is one cylindrical, and the bottom is a cylindrical shape, and magnetic sheet (7) is loaded in the tubular groove; Hexagonal threaded block (4) lower end is shaped on outside thread (41); Magnetic post (6) is to make with permanent-magnet material with magnetic sheet (7), and display pole (9) is made for plastics; Display pole is made display device, and its outer surface of upper colored red is clear eye-catching.
The utility model has the advantages that:
1. simple and reasonable.
2. easy to manufacture.
3. cheap.
4. cleaning is convenient.
5. durable in use, can bear bigger vibrations, because magnetic sheet is packed in the groove of display pole, so that the brute force of machinery shakes is not fragile.
In conjunction with the accompanying drawings and embodiments the utility model is described further:
Accompanying drawing is for showing rod-type machine oil indicator structure schematic representation
In the described demonstration rod-type of the present embodiment machine oil indicator, guide rod (2) lower end installs a contact (1), pocketed springs (3), positioning ring (5) successively on the guide rod (2), its top insert one magnetic post (6); The guide rod upper end is inserted in hexagonal threaded block (4) hole together with magnetic post (6) and positioning ring (5), positioning ring (5) is stuck on the inner convex platform of hole, display pole (9) is loaded on leads in the cap (8), its top passes the center hole of leading cap (8) top, be slidingly matched, display pole (9) floats over leads in the cap (8), and top can move up and down along center hole, leads cap (8) bottom and is threaded with hexagonal threaded block (4) top.Display pole (9) top is one cylindrical, and the bottom is a cylindrical shape, and magnetic sheet (7) is loaded in the tubular groove.
Hexagonal threaded block (4) lower end is shaped on outside thread (41); Magnetic post (6) is to make with Nd-Fe-Bo permanent magnet material with magnetic sheet (7), and display pole (9) is made for plastics; Display pole is made display device, and its outer surface of upper colored red is clear eye-catching.
Working principle is as follows: show that rod-type machine oil indicator covers by the head that hexagonal threaded block (4) lower end outside thread (41) is screwed in small tractor, machine oil enters in the head lid oil duct by oil inlet hole, arrive contact (1) bottom, machine oil makes contact (1) under the pressure of 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 positioning ring (3), because magnet principle of same-sex repulsion, make display pole (9) top rise to the relevant position simultaneously along leading cap (8) center hole, lead outside the cap (8) the most for a long time when display pole (9) exposes, 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, display pole (9) also drops to the relevant position thereupon, and display pole (9) exposes leads for what of cap (8), can find out more than the size of pressure fuel pump and the oil mass few.When machine oil indicator during at inoperative, because the effect of spring (3), each parts sets back.
Claims (5)
1, a kind of demonstration rod-type machine oil indicator, it is characterized in that by contact (1), guide rod (2), spring (3), hexagonal threaded block (4), positioning ring (5), magnetic post (6), magnetic sheet (7), lead cap (8), display pole (9) is formed, guide rod (2) lower end installs a contact (1), pocketed springs (3), positioning ring (5) successively on the guide rod (2), its top insert one magnetic post (6); The guide rod upper end is inserted in hexagonal threaded block (4) hole together with magnetic post (6) and positioning ring (5), positioning ring (5) is stuck on the inner convex platform of hole, display pole (9) is loaded on leads in the cap (8), its top passes the center hole of leading cap (8) top, be slidingly matched, a magnetic sheet (7) is equipped with in display pole (9) bottom, leads cap (8) and is threaded with hexagonal threaded block (4) top.
