Abstract
The utility model discloses a four linking bar type hinge for linking the worktable and the box body of a transmission type projector, comprising an upper seat fixed to the worktable, a lower seat fixed to the box body, and a long connecting rod, a bending connecting rod, etc. The hinge has the opening, spacing, positioning functions for the worktable and can be completely put into the projector.
Description
The utility model is the connection technique of relevant transmission type projector worktable and casing.
For ease of making and using, projector worktable and casing must be made respectively, and worktable will accurately be located casing and fastening during working state, and worktable should be opened easily and be spacing.
Existing projector worktable and casing connecting mode have:
(1) screw is fastening: worktable and casing are equipped with screw and nut respectively, taking off or tighten screw can open or stationary work-table, this mode can solve the location of worktable and fastening, but opening worktable need pull down screw and take off worktable, be not easy to use maintenance, be mounting screw, worktable and cabinet design are also limited to.
(2) universal hinge: as shown in Figure 1,1 is worktable among the figure, and 2 is casing, and 3 is hinge (two), adopts universal hinge and cooperates blocking device can solve the location of worktable and fastening, opens also more convenient.But it is attractive in appearance that this hinge some exposes influence, and for covering up hinge, bed dimension must cause waste also to limit the shape-designing of projector greater than casing.Common hinge infinite place function, the worktable opening angle can fall back voluntarily less than 90 degree, and opening angle can turn over again greater than 90 degree, need add worktable in addition and open spacing positioning means.
The utility model proposes a kind of built-in type of using for projector and have the hinge means of opening spacing locating function.
This hinge is made up of two groups of tetrad rod-type articulated mechanisms, below in conjunction with accompanying drawing 2 explanation technological scheme and enforcements thereof.
Four-bar linkage shown in Figure 2, all make with the suitable thickness steel plate, worktable 1 is fixed at the seat of honour 3, following seat 4 is fixed in casing 2, crooked short connecting rod 5 of hook solid and long connecting rod 6 are packed into by pivot pin 7,8,9,10, and seat is also rotatable up and down, the worktable opening state is seen Fig. 2 (a), and the worktable closed state is seen Fig. 2 (b).
As seen from Figure 2, worktable can stretch into the recess of bent connecting rod 5 when opening and not collide, so this hinge can be contained in worktable inside, and worktable opens to several angle as after spending greater than 90, long connecting rod 6 is held on bent connecting rod 5 protuberances and stops operating and makes worktable spacing, and lean on the worktable deadweight that long connecting rod is pressed on the bent connecting rod, vibration and general external force are made the time spent worktable and all can not rotated, thereby realize the location of opening state, be convenient to projector and more change the bulb or keep in repair, suitably enforce worktable and can make its revolution again and closure.
The transmission-type projector adopts the articulated mounting that the utility model proposes can save workbench and opens spacing detent mechanism, and articulated mounting can be placed projector inside do not expose.
Claims (2)
1, the articulated mounting that connects with casing of a kind of projector worktable is characterized in that adopting quadratic crank mechanism, by the hinge seat of honour of being fixed in worktable, is fixed in following of the hinge and the long connecting rod of casing, and short connecting rod also adds some pivot pins and connects to form.
2, articulated mechanism according to claim 1 is characterized by short connecting rod and makes crotch shape.
