As Fig. 1,2,3, shown in 4, a kind of movable propelling continuous drawer function unit, has functional unit base 1, functional unit base 1 is provided with movable part 2, functional unit base 1 has groove type plate 11 and decides mounting panel 12, on groove type plate 11, be installed with propulsive mechanism 3, chain release mechanism 4 in position and position display mechanism 5, groove type plate 11 both sides also respectively are equipped with a cover limitation locking mechanism 6, propulsive mechanism 3 is by screw mandrel 31, silk braid 32 and grooved axle sleeve 33 are formed, grooved axle sleeve 33 is fixedly mounted on the screw mandrel 31, movable part 2 has metal framework 21 and moving mounting panel 22, metal framework 21 is fixedlyed connected with moving mounting panel 22, silk braid 32 is fixedly mounted on the metal framework 21, movable part 2 passes through screw mandrel 31 with propulsive mechanism 3, silk braid 32 is fixedly connected, decide to be equipped with on mounting panel 12 and the moving mounting panel 22 movable plug-in unit 7, decide to be equipped with on the mounting panel 12 stationary part of movable plug-in unit 7, the moveable part of movable plug-in unit 7 is installed on the moving mounting panel 22, rotary screw 31, propulsive mechanism 3 promotes movable part 2 and moves in functional unit, the moveable part that is installed in the movable plug-in unit 7 on the moving mounting panel 22 of movable part 2 moves with it, and movable plug-in unit 7 can be realized and vertical bus, separate between quiet plug-in unit of main circuit and the quiet plug-in unit of auxiliary circuit, three kinds of test and connection are electrically connected state.The chain release mechanism 4 in position is by base 41 and interlock 42 mounted thereto, tripper 43 is formed, base 41 is provided with stopper slot 411, but interlock 42 is by the location positioning jam plate 421 that is arranged on move left and right in the stopper slot 411, the spring 422 and the location positioning bar 423 that are enclosed within on the jam plate of location are formed, location positioning bar 423 is fixedlyed connected with metal framework 21, location positioning bar 423 is slidingly connected by the groove that is arranged on the jam plate 421 of location, position with location positioning jam plate 421, be provided with the notch 4231 of stepping down in the place that correspondence moves to test and connects two positions on the location positioning bar 423, during rotary screw 31, metal framework 21 moves, drive in the groove of location positioning bar 423 on location positioning jam plate 421 and slide, when moving to test and link position, the existence of notch 4231 owing to step down, location positioning jam plate 421 moves to right under the effect of spring 422, in the groove 331 of the head insertion groove profile shaft cover 33 of location positioning jam plate 421, screw mandrel 31 is locked, propulsive mechanism 3 can not rotate, and movable part 2 lockings can not be moved.Tripper 43 is made up of the cardan shaft 431 that button is housed, connecting lever 432 and spring 433, and spring 433 is enclosed within on the cardan shaft 431, and connecting lever 432 is fixedlyed connected with base 41, and connecting lever 432 1 ends and cardan shaft 431 are hinged, and the other end links to each other with location positioning jam plate 421.When the needs release, pin button, cardan shaft 431 moves forward, and an end of connecting lever 432 moves forward thereupon, and connecting lever 432 rotates around fulcrum, driving location positioning jam plate 421 is moved to the left, the head of location positioning jam plate 421 breaks away from from the groove 331 of grooved axle sleeve 33, screw mandrel 31 releases, and propulsive mechanism 3 can rotate freely again, movable part 2 can move forward and backward again, thereby realizes the purpose of release.Position display mechanism 5 has display panel 51, on the display panel 51 torsion spring is housed, and torsion spring is pressed on the inclined-plane of display panel 51 on the location positioning bar 423, and along with moving forward and backward of location positioning bar 423, display panel 51 move left and right can accurately show the state of being electrically connected.Limitation locking mechanism 6 has location jam plate 61, handle 62, position restraint arc 63 and connecting rod 64, on the jam plate 61 of location spring is installed, handle 62 is fixedlyed connected with location jam plate 61, on the position restraint arc 63 torsion spring 65 is installed, position restraint arc 63 is fixedlyed connected by connecting rod 64 with metal framework 21, groove type plate 11 is provided with moving-limit groove 111, and handle 62 passes moving-limit groove 111.After functional unit propulsion functions unit cell puts in place, the location jam plate 61 that spring is housed just falls into the lockhole of functional unit cell dividing plate, functional unit base 1 is locked, when this moment, functional unit was in the separation point position, movable part 2 is near the groove type plate 11 of functional unit base 1, position restraint arc 63 is outside moving-limit groove 111, handle 62 can lift spacing jam plate 61 easily, functional unit can the propulsion functions unit cell or is withdrawed from the functional unit cell, movable part 2 is to test when rotation propulsive mechanism 3, when the link position direction is advanced, propulsive mechanism 3 with movable part 2 to test, after link position advances and puts in place, because the effect of connecting rod 64 location restraint arc 63 has turned clockwise and has entered in the moving-limit groove 111, push down handle 62, make handle 62 can not on lift, location jam plate 61 can not lift from the lockhole of function cell dividing plate, is in test thereby be implemented in functional unit, the locked function that can not shift out during link position.
