Description
technical field:
The utility model relates to a kind of projector equipment fine setting without the wear-resisting feed screw nut pair of play.
background technology:
Projector You Cheng projector, is a kind ofly image or video can be projected to the equipment on curtain, can be by different interfaces same computing machine, VCD, DVD, BD, game machine, DV etc. be connected and play corresponding vision signal.Projector is widely used in family, office, school and public place of entertainment, different according to working method, has CRT, LCD, and DLP etc. are dissimilar.
The projector equipments such as projector all need to carry out according to picture position the fine setting of three-dimensional position after installation, existing fine setting adopts feed screw nut pair to realize conventionally, if but adopted metal screw rod, nut to regulate completely, could there is larger play in it, make its degree of regulation inaccurate; Although and if adopt plastic nut can reduce play, because meeting with stresses of plastic nut is less, easily damage, serviceable life is short, is unfavorable for that it uses for a long time.
summary of the invention:
The purpose of this utility model is to provide a kind of projector equipment fine setting without the wear-resisting feed screw nut pair of play, this projector equipment fine setting is simple in structure, reasonable in design without the wear-resisting feed screw nut pair of play, be conducive to overcome the problem that existing feed screw nut pair exists larger play, and can improve its serviceable life.
The technical solution of the utility model;
The fine setting of the utility model projector equipment is without the wear-resisting feed screw nut pair of play, it is characterized in that: comprise a metal screw mandrel and be located at the nut piece on screw mandrel, described nut piece includes a plastic jacket and is fixed on the metal nuts being threaded with metal screw mandrel in plastic jacket body, on described plastic jacket for wearing perforation and the screw mandrel wringing fit of screw mandrel.
Further, above-mentioned plastic jacket is rectangular-shaped, in rectangular parallelepiped side, is provided with two circular bosses, described plastic jacket is fastened and is formed by symmetrical halved body, at a semi-circular boss medial surface, be provided with protruding nail, at relative semi-circular boss medial surface, be provided with shrinkage pool accordingly, for the fixing protruding nail of pegging graft.
Further, above-mentioned plastic jacket is rectangular-shaped, and described plastic jacket is fastened and formed by symmetrical halved body.
Further, above-mentioned metal nuts is positive hexagonal nut, at halved body, is respectively equipped with for holding the regular hexagon groove of positive hexagonal nut.
The fine setting of the utility model projector equipment consists of plastic jacket and metal nuts the nut piece being connected with wire rod thread without the wear-resisting feed screw nut pair of play, by metal nuts, is connected with wire rod thread, guarantees its serviceable life; By plastic jacket, overcome the play that metal nuts and screw mandrel produce.
The utility model projector equipment fine setting is simple in structure, reasonable in design without the wear-resisting feed screw nut pair of play, is conducive to overcome the problem that existing feed screw nut pair exists larger play, and the little problem of plastic nut stress, thereby can improves nut piece serviceable life.
accompanying drawing explanation:
Fig. 1 is front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is Fig. 1 explosive view;
Fig. 4 is that the utility model is used state profile construction schematic diagram;

embodiment:
The fine setting of the utility model projector equipment is without the wear-resisting feed screw nut pair of play, comprise a metal screw mandrel 1 and be located at the nut piece 2 on screw mandrel 1, described nut piece 2 includes a plastic jacket 3 and is fixed on the metal nuts 4 being threaded with metal screw mandrel 1 in plastic jacket 3 bodies, by metal nuts, be connected with wire rod thread, guarantee its serviceable life, on plastic jacket 3 for wearing the perforation 5 and screw mandrel 1 wringing fit of screw mandrel 1, due to this perforation 5 and screw mandrel 1 wringing fit, make plastic jacket 3 by fastening this screw mandrel of perforation, reduce the play of screw mandrel and nut.
Wherein embodiment mono-, above-mentioned plastic jacket is rectangular-shaped, in rectangular parallelepiped 6 sides, be provided with two circular bosses 7, described plastic jacket is fastened and is formed by symmetrical halved body 8, at a semi-circular boss medial surface, be provided with protruding nail 9, at relative semi-circular boss medial surface, be provided with shrinkage pool 10 accordingly, for the fixing protruding nail of pegging graft.
Wherein embodiment bis-, and above-mentioned plastic jacket is rectangular-shaped, and described plastic jacket is fastened and formed by symmetrical halved body.This embodiment bis-is with the difference of embodiment mono-, embodiment and there is no two circular bosses.
Further, for better positioning metal nut, above-mentioned metal nuts is positive hexagonal nut, at halved body, is respectively equipped with for holding the regular hexagon groove 11 of positive hexagonal nut.
The fine setting of the utility model projector equipment consists of plastic jacket and metal nuts the nut piece being connected with wire rod thread without the wear-resisting feed screw nut pair of play, by metal nuts, is connected with wire rod thread, guarantees its serviceable life; By plastic jacket, overcome the play that metal nuts and screw mandrel produce.
The utility model projector equipment fine setting is simple in structure, reasonable in design without the wear-resisting feed screw nut pair of play, is conducive to overcome the problem that existing feed screw nut pair exists larger play, and the little problem of plastic nut stress, thereby can improves nut piece serviceable life.
