Abstract
The utility model relates to a kind of wear-resisting curtain pull ring structure, comprises a torus, it is characterized in that: described torus inner edge is provided with annular groove, clogs the wear-resistant block having polyformaldehyde to make in described annular groove.The production technology of the wear-resisting curtain pull ring structure of the utility model, pre-torus, and annular groove is processed on torus inner edge; Then the wear-resistant block made of injection mo(u)lding polyformaldehyde, in the wear-resistant block made by polyformaldehyde press-in annular groove, blend compounds is firmly bonding, finally removes burr and polished surface.The wear-resistant block that the utility model polyformaldehyde is made has the hardness of metalloid, intensity and rigidity, within the scope of very wide temperature and humidity, all there is the premium properties such as good self lubricity, good fatigue durability, by inlaying the wear-resistant block establishing polyformaldehyde to make in torus inner edge, even if thus make draw ring still have good creep resistant characteristic, geometrical stability and impact property at low temperatures.Be conducive to the self lubricity improving curtain pull ring, reduce its friction and wear.
Description
Technical field
The utility model relates to a kind of accessory of curtain, particularly a kind of wear-resisting curtain pull ring structure.
Background technology
At present, the closure or openness of curtain all adopt hanging-ring type curtain usually, hanging-ring type curtain is enclosed within the cross bar of curtain suspension rod by the draw ring of casement, with hand or stay cord back and forth tractive casement realize the closure or openness of curtain to drive draw ring to slide on cross bar, only very little in draw ring inner edge one piece of contact due to draw ring and cross bar, therefore, at the especially severe worn and torn in this position of draw ring, thus people pull casement to require great effort especially in use for some time.
Summary of the invention
The purpose of this utility model is to provide a kind of wear-resisting curtain pull ring structure, this wear-resisting curtain pull ring reasonable in design, is conducive to the self lubricity improving curtain pull ring, reduces its friction and wear.
The wear-resisting curtain pull ring structure of the utility model, comprises a torus, it is characterized in that: described torus inner edge is provided with annular groove, clogs the wear-resistant block having polyformaldehyde to make in described annular groove.
Above-mentioned torus is wooden circle.
Above-mentioned torus is that circle moulded by wood.
Above-mentioned torus is plastic ring.
Above-mentioned torus is nylon ring.
The cross section of above-mentioned annular groove is dovetail groove, matches with dovetail groove in Polyformaldehyde wear-resistant block bottom, and Polyformaldehyde wear-resistant block top is curved arch, and Polyformaldehyde wear-resistant block top edge cover ring connected in star top edge.
The cross section of above-mentioned annular groove is rectangle, matches with rectangular channel in Polyformaldehyde wear-resistant block bottom, and Polyformaldehyde wear-resistant block top is curved arch, and Polyformaldehyde wear-resistant block top edge cover ring connected in star top edge.
The production technology of the wear-resisting curtain pull ring structure of the utility model, pre-torus, and annular groove is processed on torus inner edge; Then the wear-resistant block made of injection mo(u)lding polyformaldehyde, in the wear-resistant block made by polyformaldehyde press-in annular groove, blend compounds is firmly bonding, finally removes burr and polished surface.
The wear-resistant block that the utility model polyformaldehyde is made has the hardness of metalloid, intensity and rigidity, within the scope of very wide temperature and humidity, all there is the premium properties such as good self lubricity, good fatigue durability, by inlaying the wear-resistant block establishing polyformaldehyde to make in torus inner edge, even if thus make draw ring still have good creep resistant characteristic, geometrical stability and impact property at low temperatures.Be conducive to the self lubricity improving curtain pull ring, reduce its friction and wear.

Detailed description of the invention
The wear-resisting curtain pull ring structure of the utility model, comprises a torus 1, and described torus 1 inner edge is provided with annular groove 2, clogs the wear-resistant block 3 having polyformaldehyde to make in described annular groove 2.
Above-mentioned torus can mould circle, plastic ring or nylon ring etc. for wooden circle, wood.
Embodiment one, the cross section of above-mentioned annular groove is dovetail groove, matches with dovetail groove in Polyformaldehyde wear-resistant block bottom, and Polyformaldehyde wear-resistant block top is curved arch, and Polyformaldehyde wear-resistant block top edge cover ring connected in star top edge.
Embodiment two, the cross section of above-mentioned annular groove is rectangle, matches with rectangular channel in Polyformaldehyde wear-resistant block bottom, and Polyformaldehyde wear-resistant block top is curved arch, and Polyformaldehyde wear-resistant block top edge cover ring connected in star top edge.
The production technology of the wear-resisting curtain pull ring structure of the utility model, pre-torus, and annular groove is processed on torus inner edge; Then the wear-resistant block made of injection mo(u)lding polyformaldehyde, in the wear-resistant block made by polyformaldehyde press-in annular groove, blend compounds is firmly bonding, finally removes burr and polished surface.
The wear-resistant block that the utility model polyformaldehyde is made has the hardness of metalloid, intensity and rigidity, within the scope of very wide temperature and humidity, all there is the premium properties such as good self lubricity, good fatigue durability, by inlaying the wear-resistant block establishing polyformaldehyde to make in torus inner edge, even if thus make draw ring still have good creep resistant characteristic, geometrical stability and impact property at low temperatures.Be conducive to the self lubricity improving curtain pull ring, reduce its friction and wear.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
