Abstract
The utility model relates to a bracket-type rotating shaft adopting self-lubricating gaskets, which comprises a cast and a bracket rotating shaft, wherein the cast is connected with a base; the bracket rotating shaft is connected with a display body; and the cast is rotationally connected with the bracket rotating shaft through a bolt pillar and a nut. The bracket-type rotating shaft is characterized in that a first self-lubricating gasket and a second self-lubricating gasket are arranged on the bolt pillar in a penetrating manner; a positioning column that is connected with the cast in a positioning manner is arranged on the first self-lubricating gasket; a tongue piece structure that is connected with the bracket rotating shaft in a positioning manner is arranged on the second self-lubricating gasket; and Teflon coatings are arranged on the mutual contact surfaces of the first self-lubricating gasket and the second self-lubricating gasket. The bracket-type rotating shaft adopts the two self-lubricating gaskets that are matched mutually to achieve the rotating function of the bracket rotating shaft without grease lubrication.
Description
Technical field
The utility model relates to a kind of support rack type rotating shaft of adopting the selflubricating pad, is applicable to the display device with rotation or pitching function.
Background technique
At present, the metallic shim that in the rack shaft (Hinge) of the TV with rotation, pitching function, display device, uses, its lubricating function all is to realize through be coated with all kinds of lubricant greases at gasket surface.Have following shortcoming: (1) is the lubricating function when realizing rotation through all kinds of lubricant greases of surfaces coated to employed pad among the Hinge; Owing to exist inevitable grease too much or smear inhomogeneous situation; In the Hinge using process, often occur causing grease to overflow; Directly contact with plastic cement material in the support, cause the support plastic cement to be corroded and rupture; (2) owing to phenomenons such as oxidation, curing can appear in grease in the Hinge using process, and often cause the spinfunction validity forfeiture of Hinge, shorten working life; (3) existing structure need be prone to cause leakage through manual oiling, influences the Hinge quality, and is unfavorable for practicing thrift human cost.
Summary of the invention
In view of the deficiency of existing technology, the purpose of the utility model is to provide a kind of support rack type rotating shaft with self-lubricating function, and this support rack type rotating shaft adopts the two selflubricating pads that match to realize the spinfunction of rack shaft, need not grease lubrication.
To achieve these goals; The technological scheme of the utility model is: a kind of support rack type rotating shaft of adopting the selflubricating pad; Comprise foundry goods that is connected with base and the rack shaft that is connected with monitor body; Said foundry goods rotates with rack shaft with nut through bolt column and is connected, and it is characterized in that: be equipped with the first selflubricating pad and the second selflubricating pad on the said bolt column, the said first selflubricating pad is provided with the locating column that is located by connecting mutually with foundry goods; The said second selflubricating pad is provided with the tongue piece structure that is located by connecting mutually with rack shaft, and the face that is in contact with one another of the said first selflubricating pad and the second selflubricating pad is equipped with teflon coatings.
Preferably, the thickness of said teflon coatings is 0.02 ~ 0.06mm.
Preferably, the said first selflubricating pad and the second selflubricating pad are metallic shim.
Compared with prior art; The utlity model has following advantage: the face that is in contact with one another of two selflubricating pads all is coated with the Teflon of premium properties such as having self lubricity, rub resistance, resistant of high or low temperature, corrosion resistance and high flame retardant; Can the friction factor between pad be reduced to minimum; That realizes Hinge exempts from the grease self-lubricating function, can avoid thoroughly thus that grease promotes the quality of support to the corrosive action of support plastic cement material among the former Hinge.
Description of drawings
Fig. 1 is the utility model embodiment's a organigram.
Among the figure: the 1-foundry goods, the 2-rack shaft, the 3-bolt column, the 4-nut, the 5-conventional pads, the 6-first selflubricating pad, the 6-1-locating column, the 7-second selflubricating pad, 7-2-tongue piece structure, A-is in contact with one another face.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration.
With reference to figure 1; A kind of support rack type rotating shaft of adopting the selflubricating pad; Comprise the foundry goods 1 and the rack shaft that is connected with monitor body 2 that are connected with base, said foundry goods 1 rotates with rack shaft 2 with nut 4 through bolt column 3 and is connected, and the pad of said nut 4 adopts conventional pads 5; Be equipped with the first selflubricating pad 6 and the second selflubricating pad 7 on the said bolt column 3; The said first selflubricating pad 6 is provided with the locating column 6-1 that is located by connecting mutually with foundry goods 1, and the said second selflubricating pad 7 is provided with the tongue piece structure 7-1 that is located by connecting mutually with rack shaft 2, and the face that the is in contact with one another A of the said first selflubricating pad 6 and the second selflubricating pad 7 is equipped with teflon coatings.
In the present embodiment, the thickness of said teflon coatings is 0.02 ~ 0.06mm, preferentially chooses 0.04mm, can choose numerical value according to concrete use condition; The said first selflubricating pad 6 and the second selflubricating pad 7 are metallic shim.The said first selflubricating pad 6 and the second selflubricating pad 7 are the macromolecular material-PTFE (teflon that have self lubricity, rub resistance, resistant of high or low temperature, corrosion resistance and high flame retardant through high temperature sintering, spraying at the substrate surface of metallic shim; Also claim Teflon); Can the friction factor between the Hinge Intermediate gasket be dropped to minimumly, that realizes Hinge exempts from the grease self-lubricating function.Can thoroughly avoid among the former Hinge grease to the corrosive action of support plastic cement material thus, promote the quality of support.
Gasket surface has following function after PTFE (teflon) spraying: (1) rub resistance: PTFE has lowest friction coefficient in the plastic cement, and when the pad load was slided, friction factor was merely between the 0.05-0.15; (2) resistant of high or low temperature: the PTFE coating can remain on not embrittlement under the cryogenic temperature applicable to-190-260 degree centigrade environment, does not melt under the high temperature; (3) viscosity not: nearly all material is not bonding with PTFE; (4) corrosion resistance: PTFE can protect part to avoid suffering the chemical corrosion of any kind of; (5) limited oxygen index of high flame retardant: PTFE is below 90.
In the present embodiment, the said first selflubricating pad 6 and the second selflubricating pad 7 are through the high temperature sintering mode PTFE to be sintered in substrate surface at the substrate surface that is used for forming gasket earlier, and the PTFE skin depth is chosen between 0.02 ~ 0.06mm according to use condition; According to employed all kinds of pad specifications among the Hinge the direct impact briquetting of substrate can be obtained to have the pad of self-lubricating function again; In the Hinge assembling process, PTFE sprayed surface (teflon coatings) in the pad that has phase mutual friction turning effort is installed and fixed face-to-face, can realize the oil-free self lubrication rotation between pad.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
