Description
Technical field
The utility model relates to a kind of pivot device that is applied on the electronic product, refers to especially be provided with the oil storage annular groove at location piece, is formed with the anti-leakage of oil pivot device structure of special-purpose oil storage space with cam assembling back.
Background technique
The common pivot device that is used for electronic product of people; be as being connected in screen with between body; so that screen and body relatively rotate; and can reach purposes such as opening use or folding collection; the pivot device of this class is to utilize the member of interfering each other; produce suitable frictional force and torsion; in process in relative rotation; especially the moment that transfers kinetic friction from static friction to; understand because of the lack of lubrication between interference member, and impact the feel not good (opening or close overweight) that the user operates, hereat; between the upper projecting face of interference member, can be provided with oil-bearing structure (normally oil storage hole or oil storage tank) usually, and promote the lubrication effect when relatively rotating.
But the pivot device of lifting lubrication effect in use, though good lubricating effect is arranged, behind rotary manipulation repeatedly, lubricant grease can be because of the rotation pressurized, cause lubricant grease to pollute by the gap overflow between member, or even lubricant grease is a large amount of run off after, cause to become dry and astringent between member and be difficult to operation; As shown in Figure 1, the novel patent of TaiWan, China M316347 number " turning shaft structure of tool leakproof functional oil ", be in pivot device 1, to be provided with interference component 11, and the approximal surface position of interference component is to coat to be provided with an axle sleeve 12, in view of the above in use, be to utilize axle sleeve 12 to coat the approximal surface of interference component 11 phase mutual friction, and prevent therebetween lubricant grease overflow or loss.In fact, because axle sleeve 12 is not to coat interference component 11 fully, and and 11 of interference components are formed with the slit, so the lubricant grease of overflow is to flow in the described slit, though the lubricant grease of overflow can outwards not flow out and pollute, but the minimizing of lubricant grease still can make approximal surface become dry and astringent, and has influence on operator's use feel, even causes wearing and tearing.
Again as shown in Figure 2, the novel patent of TaiWan, China M323791 number " can prevent the pivot device of oil leak ", also once disclosed a kind of pivot device 1 ' that is provided with protruding positioning block 11 ' and recessed positioning block 12 ', and coat in the approximal surface position of protruding positioning block 11 ' and recessed positioning block 12 ' and to be provided with a flinger ring 13 ', its principle is close with the structure of aforementioned pivot device 1, and function and shortcoming are also identical, so no longer given unnecessary details.Anti-oil-leakage structure in the above-mentioned patent can't solve the problem of anti-leakage of oil at all, only can prevent the pollution of lubricant grease, so be necessary to be improved.
So the utility model designer accumulation designs the experience of pivot device for many years, design a kind of novel pivot device that is provided with special-purpose oil storage space, so that properly store the pollution that lubricant grease prevents that overflow from causing, and can promote the smooth and easy feel when using and prolong whole working life.

During assembling, as Fig. 4, shown in Figure 9, be that banking stop 3, support 4, location piece 5, cam 6 and elastic element 7 are arranged in the rotating shaft 2 in regular turn, at last again by fixed block 8 in addition spiral shell establish fixing, make closing mutually between member in twos, and on 6 on banking stop 6 and 4 on support, support 4 and 5 of location pieces and location piece 5 and cam, be formed with an airtight oil storage space respectively, be provided with properly storing lubricant grease, smoothness when the lifting rotating shaft drives each member rotation, and reduce the frictional wear of member, more can effectively prevent the overflow of lubricant grease.
During use, as Fig. 9, shown in Figure 10, cam 6 can be along with the rotation of rotating shaft 2, and rotate with respect to location piece 5, because corresponding 62,521 mutual contacts of male and fomale(M﹠F) cause cam 6 to have the action that moves back and forth, and the approximal surface of cam 6 can remain on and moves back and forth in the ring barricade 523 of the first oil storage annular groove 52 in the rotation process, so the lubricant grease that stores in oil storage space has enough spaces to flow, and the pollution condition of lubricant grease overflow just can not take place; Moreover, banking stop 3 is tight closing support 4 one sides, because friction plate 43 meetings and the 42 surperficial closings mutually of the second oil storage annular groove in the oil storage space, and can properly store lubricant grease, again, the protuberance 45 of support 4 is inserted in the 3rd oil storage annular groove 53, with the surface of contact banking stop 55 or tight closing the 3rd oil storage annular groove 53 of friction plate, and reaches the purpose of properly storing lubricant grease.
Fig. 3～shown in Figure 9 as mentioned above, the utility model will have following advantage when implementing:
The utility model mainly is to be provided with the first oil storage annular groove 52 in location piece 5 one sides, cam 6 is movably set in the first oil storage annular groove 52, make the approximal surface of cam 6 be positioned at the ring barricade 523 of the first oil storage annular groove 52, and be formed with airtight oil storage space, properly to store lubricant grease, the pollution that not only can prevent the lubricant grease overflow and cause, and can promote the feel smoothness when using and increase the service life.
Moreover, because support 4 of the present utility model is provided with the second oil storage annular groove 42, and be provided with friction plate 43 in the second oil storage annular groove 42, after support 4 and the banking stop 3 mutual closings, can form another airtight oil storage space, be used for reducing the friction of 4 on banking stop 3 and support, also prevent the lubricant grease overflow, promote and use feel and advantage such as increase the service life.
And 5 of support 4 of the present utility model and location pieces are provided with protuberance 45 and the 3rd oil storage annular groove 53, can form airtight oil storage space after the closing, prevent the lubricant grease overflow, advantage such as promote to use feel and increase the service life.
Again, be provided with a stopper part 54 and a banking stop 55 in the 3rd oil storage annular groove 53 of location piece of the present utility model, and banking stop 55 can and rotating shaft 2 form to rotate and link, and form the limit effect of two retaining points with aforementioned banking stop 3, not only can promote the block effect, the advantage that increases the service life is also arranged.
More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications; change or equivalence; as: separately between banking stop and support; be provided with airtight oil storage space between support and location piece and between location piece and cam; or between support and location piece, set up transition regimes such as a confined planes; or elastic element changed into shell fragment or spring; or at friction plate; oil storage annular groove or protuberance are provided with oil storage hole etc., all will fall within the protection domain of the present utility model.
