Abstract

The utility model discloses a slow-falling rotating shaft of a toilet bowl cover board, which consists of a sealing element, a shaft housing and a shaft core, wherein, the shaft core is provided with a set or a plurality of sets of oiled control mechanisms; each set of oiled control mechanism consists of an oil blocking plate arranged on the shaft core, an oil passing plate and a roller pin arranged between the oil blocking plate and the oil passing plate which is provided with one or a plurality of oil passing holes. The slow-falling rotating shaft is particularly suitable for being manufactured by adopting metal material, and the oil blocking plate and the oil passing plate are integrated with the shaft core into a whole, thereby ensuring the diameter of the rotating shaft to be smaller, prolonging the service life and improving the working stability. The roller pin moves evenly and smoothly when working, therefore, the cover board moves evenly and smoothly when falling down; the slow-falling rotating shaft is made of plastic material, thereby ensuring that the volume is smaller than that of the prior product.

Description

The lavatory lid rotating shaft that falls slowly

Technical field

The utility model relates to the rotating shaft that falls slowly of a kind of lavatory lid.

Background technology

The rotating shaft that falls slowly of existing lavatory lid, it crosses the structure and the intensity restriction of oily blade, make the rotating shaft diameter be difficult to miniaturization, and the life-span is relatively poor, the large diameter rotating shaft that falls slowly cooperates with cover plate and bearing can take bigger space, makes the structure outward appearance of cover plate and bearing be subjected to very big restriction.So need minor diameter, the life-span, the long rotating shaft that falls slowly cooperated with cover plate and bearing, made the design of cover plate and bearing that bigger brought into play space be arranged.

The utility model content

The utility model has problems at prior art, proposes a kind of pivot structure that falls slowly of simple compactness.

The lavatory lid of the present utility model rotating shaft that falls slowly contains seal, and an axle sleeve and an axle core is characterized in that: an axle core is provided with one group or some groups and crosses oily controlling organization; Cross oily controlling organization by being located at a grease baffle, the oily sheet of mistake on the core and being located at grease baffle and the needle roller crossed in the middle of the oily sheet is formed for every group, the oily sheet of mistake is provided with one or several oil-through holes.

For making the rotating shaft stable working, the oily controlling organization of mistake of two groups of symmetries is adopted in the rotating shaft that falls slowly.

The utility model is particularly suitable for adopting the metal material manufacturing, grease baffle and to cross oily sheet one-body molded with the axle core, thus make the more miniaturization of rotating shaft diameter, increase the service life and strengthen job stability.Because needle roller when work motion is evenly level and smooth, so cover plate motion uniform and stable when falling.Adopt plastic production the utility model, can make the miniaturization of volume ratio existing product equally.

Fig. 3 is the utility model embodiment overall schematic;

The state cutaway view falls in Fig. 4 a for the utility model embodiment is slow;

Fig. 4 b is the utility model embodiment open mode cutaway view.

Wherein: 1. nut, 2. pad, 3. end cap, 4. sealing ring a, 5. axle sleeve, 6. needle roller, 7. sealing ring b, a 8. core, 9. grease baffle is 10. crossed oily sheet, 11. oil-through holes.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is further specified.As Fig. 1 is the utility model embodiment 1 exploded view, and pad 2, end cap 3, sealing ring a4 (sealing ring a4 is sheathed in the groove of end cap 3) be sheathed in regular turn goes into axle sleeve 5; Needle roller 6 is located at grease baffle 9 and is crossed in the middle of the oily sheet 10, and sealing ring b7 is sheathed in a core 8 bottom grooves, and nut 1 is fixed in 8 upper ends, axle center, and tightens, and is assembled into the overall schematic as Fig. 3.

Cover plate delays when falling, and as Fig. 4 a, rotating shaft turns clockwise, and because of the effect of needle roller 6 and grease baffle 9, damping oil can only push through between the slit of needle roller 6 and grease baffle 9, thereby plays the slow effect of falling; Otherwise when cover plate was opened, rotating shaft was rotated counterclockwise, and damping oil can pass through on slit and oil-through hole 11 smoothly, and when therefore opening, feel is very light.

Fig. 2 is the utility model embodiment 2 axle center schematic diagrames, and its structure is identical with embodiment 1 with operation principle.

Claims

1. the lavatory lid rotating shaft that falls slowly contains seal, and an axle sleeve and an axle core is characterized in that: an axle core is provided with one group or some groups and crosses oily controlling organization; Cross oily controlling organization by being located at a grease baffle, the oily sheet of mistake on the core and being located at grease baffle and the needle roller crossed in the middle of the oily sheet is formed for every group, the oily sheet of mistake is provided with one or several oil-through holes.

2. the lavatory lid as claimed in claim 1 rotating shaft that falls slowly, it is characterized in that: the rotating shaft that falls is slowly crossed oily controlling organization by two groups and is formed.
