Embodiment
Fig. 1 is the one-piece construction synoptic diagram of an embodiment of the utility model.A kind of projection magic lamp plate-changing mechanism of the utility model, be used for when carrying out projection, changing automatically lantern slide, lantern slide is arranged in the lantern slide geometrical clamp 2, the fuselage of this projection magic lamp plate-changing mechanism is made of left and right side plate 1 and backboard 18, web joint 3 is contained in the upper end of left and right side plate 1, back forms lantern slide storage section, and lantern slide geometrical clamp 2 is installed in back.
Waist is provided with and changes the sheet control device, and this changes in the sheet control device, and support 9 is connected with left side plate 1, is equiped with power supply 10 and motor 11 in the front of support 9, is equiped with screw rod 5 at support 9 back sides, and screw rod 5 is connected with 11 in motor.
In use, lantern slide is put into lantern slide geometrical clamp 2, then lantern slide geometrical clamp 2 is put into the back of projection magic lamp plate-changing mechanism, the base of lantern slide geometrical clamp 2 is dropped on the helicla flute of screw rod 5 (as shown in Figure 2), operating personnel's energized 10, motor 11 drives screw rod 5 and rotates, along with the helicla flute rotation, the lantern slide geometrical clamp 2 that drops on the outermost layer helicla flute just drops down, drop on the block 15 of projection in zone below, on 17, pushed down by left and right sides compressing tablet 14 simultaneously, this moment, the pattern part of lantern slide was just in time corresponding with projection in zone 26, thereby realized once changing the sheet operation.
Fig. 2 to Fig. 6 has further shown the structure of the utility model embodiment.At support 9 back sides, also be provided with between motor 11 and the screw rod 5 one with 11 positioning disks that are connected 6 of motor, positioning disk 6 can be with 11 rotations synchronously of motor with screw rod 5, positioning disk 6 is provided with a groove 13; At support 9 back sides, positioning disk 6 one sides are provided with a limit switch 16 that links to each other with power supply 10, and the side of the banking stop of this limit switch 16 and positioning disk 6 fits.
The top of the left and right side plate 1 of fuselage is provided with many groups inserted slot 20 of mutual correspondence; 20 groups of numbers of the helicla flute number of plies on the screw rod 5 and inserted slot are identical.
When practical operation, the quantity of the lantern slide geometrical clamp of depositing in the projection magic lamp plate-changing mechanism 2 is identical with the spiral fluted number of plies on the screw rod 5, and the base of outmost lantern slide geometrical clamp 2 is dropped on the helicla flute outermost layer.This design makes motor 11 when rotating a week, just drive positioning disk 6 and rotate a week, thereby make the groove 13 on it also move a week, because the banking stop of limit switch 16 and the side of positioning disk 6 fit, when groove 13 rotates to the position of intersecting with the banking stop of limit switch 16, the banking stop of limit switch 16 can be affixed to groove 13, thereby make limit switch disconnect, because limit switch 16 links to each other with power supply 10, then limit switch 16 disconnects motor 11 outages is stopped operating, and guarantees to stop operating after motor 11 rotates a circle.This design stops after making motor 11 rotate a circle automatically, the outmost lantern slide geometrical clamp 2 in projection magic lamp plate-changing mechanism top this moment falls, thereafter lantern slide geometrical clamp 2 then order along the outside mobile one deck of helicla flute, when switching on, ranked second individual lantern slide geometrical clamp 2 at first and fall ready for the second time.
In the present embodiment, projection magic lamp plate-changing mechanism also is provided with a device that is used to remove sheet, with reference to figure 2,3,6, this structure of removing the sheet device is: a positioning rod 8 is installed in support 9 back side screw rods 5 one sides, its top and support 9 flexibly connect, be fixed with connection washer 7 between screw rod 5 and the positioning disk 6, be fixed with locating shaft 4, above fuselage bottom link stopper 15,17, swingle 19 is installed at connection washer 7 cylindrical positions; Rotate with screw rod 5 when connecting washer 7, drive locating shaft 4 rotations, when locating shaft 4 forwarded bottom connection with backstay 8 to and touches, backstay 8 axle 4 that can be positioned backed down, and is that move in the center of circle with backstay 8 tops; Swingle 19 is installed in side plate 1 bottom by support chip 12, swingle 19 two ends are provided with driven end 23 and top flat end 24, be provided with a spring 21 between its driven end 23 and the support chip 12, one of described backstay 8 is connected with steel wire 22, the other end of steel wire 22 passes fuselage side plate 1, support chip 12 and spring 21, link to each other with the driven end 23 of swingle 19, in backboard 18 bottoms, have slotted hole 25 on the position that adapts with the top flat end 24 of swingle 19, can make the top flat end 24 of swingle 19 lean out from slotted hole 25.
Remove the sheet Design of device and make that changing next lantern slide when projection in zone 26 has lantern slide need not the staff manually with last sheet taking-up, and can replace automatically.For example, when operating personnel after a slideshow finishes, energized 10 is during motor 11 rotation, backstay 8 axle that can be positioned 4 backs down, with backstay 8 tops is that move in the center of circle, because of steel wire 22 is connected on the backstay 8, so moving of backstay 8 will spur steel wire 22, thereby driven rotary bar 19, swingle 19 is with the pulling of steel wire 22, and its top flat end 24 leans out from slotted hole 25, and the bottom of lantern slide geometrical clamp 2 is backed down from block 15,17.This moment, motor 11 was rotated further, and drove screw rod 5 and was rotated further, and next lantern slide geometrical clamp 2 falls on the block 15,17, and limit switch 16 outages are finished one and changed the sheet cycle.
The utility model projection magic lamp recorder changer can substitute traditional hand and insert lantern slide, accurate positioning, and replacing speed is fast, and is easy to operate, can be contained on any overhead projector to be used, and realizes auto-slide, can be the stage performance and bring good prospect.
