Description

A kind of built-in oilpaper structure of proofing dust and protecting movement

Technical field

It the utility model is related to a kind of hand internal structure, the built-in oilpaper structure of especially a kind of proofing dust and protecting movement.

Background technology

In general the watchcase of stem-winder is alloy material, and closes the bottom and Steel material in watchcase bottom surface, due to watchcase Can not very it be coincide when in technique with bottom, so necessarily there are granulated metal bits when combining in them, These metal fillings can enter watch core in use, increase the abrasion of mechanical transmission structure in watch core.In the industry in order to reduce such case Generation, typically inner cover can be made in watchcase and dustproof construction is done on inner cover.Its shortcoming is wrist-watch must to be accomplished certain thickness Degree can just admit inner cover.Part extra-thin watch is just not suitable for using the technology.

The content of the invention

In view of the shortcomings of the prior art, the utility model provides a kind of movement dustproof construction that need not thicken watchcase.

The technical solution of the utility model is：

A kind of built-in oilpaper structure of proofing dust and protecting movement, it is characterised in that：It includes watchcase, movement, pressure ring and oilpaper, The watchcase center of inside is provided with movement, the movement side connection wrist-watch handle, and table is stretched out in the outer end of the wrist-watch handle On the outside of shell, it is easy to adjust pointer by turn wrist-watch handle, the back side of the movement is covered with an oilpaper, the oilpaper periphery The back side is propped up by a pressure ring and pressure ring is brought into close contact with watchcase, and the pressure ring cooperation wrist-watch handle is provided with a rectangular v notch v, Pressure ring is non-interference with wrist-watch handle, and the pressure ring is provided with annular boss, and it is to prop up bottom after bottom covers that it, which is acted on, Support oilpaper periphery so that oilpaper tightly muffles movement.

The pressure ring and its annular boss are integrally formed using plastic material, can effectively ensure that its intensity and elasticity.

The pressure ring is provided with multiple through holes, is easy to reduce materials, saves cost.

Using double-deck oilpaper, it is made up of the oilpaper the oilpaper piece of two layers of pressing.

Operation principle of the present utility model：Movement first is muffled with oilpaper, then pressure ring is pushed down to the periphery of oilpaper, most bonnet Upper bonnet.Bonnet and the watchcase metal dust with reference to caused by are understood because contacting oilpaper during the use of wrist-watch by constantly jolting And it is adhered on oilpaper.Oilpaper after long-term use will not because having outstanding folding resistance energy, water imbibition and water proofing property Aging and there is certain anti-rust action to movement.There is good toughness in itself additionally, due to oilpaper and contain drying oil, i.e., Make the generation friction with wrist-watch handle scrape damage it is also very small, can be neglected.

The beneficial effects of the utility model are：The utility model is simple in construction, and oilpaper is pressed in the movement back side by pressure ring, It can prevent bottom and the watchcase metal dust with reference to caused by from entering movement by the protection of oilpaper, because oilpaper is very thin, therefore nothing Watchcase need to be thickeied, is adapted to the manufacture of all kinds of wrist-watches.

Embodiment

Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：

As Figure 1-3, the built-in oilpaper structure of a kind of proofing dust and protecting movement, it includes watchcase 1, movement 11, the and of pressure ring 3 Oilpaper 4, the center of inside of watchcase 1 are provided with movement 11, and the side of movement 11 connects 2, the 2 of the wrist-watch handle of wrist-watch handle Outer end stretch out the outside of watchcase 1, be easy to adjust pointer by turning the 2 of wrist-watch handle, the back side of the movement 11 is covered with one Oilpaper 4, the periphery back side of oilpaper 4 is propped up by a pressure ring 3 and pressure ring 3 is brought into close contact with watchcase 1, and the pressure ring 3 coordinates wrist-watch 2 be provided with a rectangular v notch v 32, the 2 of pressure ring 3 and wrist-watch handle are non-interference, and the pressure ring 3 is provided with annular boss 31.

The pressure ring 3 and its annular boss 31 are integrally formed using plastic material, can effectively ensure that its intensity and elasticity.

The pressure ring 3 is provided with multiple through holes, is easy to reduce materials, saves cost.

As shown in figure 4, the oilpaper 4, using double-deck oilpaper, it is made up of the oilpaper piece of two layers of pressing, respectively One oilpaper piece 41 and the second oilpaper piece 42.

Simply illustrate principle of the present utility model and most preferred embodiment described in above-described embodiment and specification, do not taking off On the premise of the spirit and scope of the utility model, the utility model also has various changes and modifications, these changes and improvements Both fall within claimed the scope of the utility model.
