Abstract
The utility model discloses a top cover locking device for a centrifuge. The utility model is characterized in that a micro switch is arranged on a mounting plate; two guiding sleeves are arranged on an outer shell; one torsional spring and a locking block, and a sleeve cylinder are arranged into an integral body, and are arranged on one guiding sleeve, and the other torsional spring and a movable block are arranged on the other guiding sleeve; one end of a pull rod and one end of the locking block are movably connected; one end of the movable block can be contacted with the micro switch, and the movable block can be contacted with the locking block. The utility model can cause a top cover of a centrifuge to automatically open and lock, the utility model is matched with the corresponding control circuit, and the utility model has the function that the top cover can not be closed tightly so that the centrifuge can not be started to interlock. The utility model has the advantages of flexible action and safety.
Description
The utility model relates to a kind of top cover locking device that is used for centrifuge.
Existing centrifuge top cover locking device does not possess the function of automatic unlatching and auto lock, and has the unlatching effort, complex structure, the fragile deficiency that waits.
The purpose of this utility model is to provide a kind of improved centrifuge top cover locking device, and it can make the top cover of centrifuge open automatically.
The technical solution of the utility model is achieved in that the top cover locking device that is used for centrifuge, it mainly comprises top cover, installing plate, be contained in the shell on the installing plate, electromagnet and pull bar, gate stop that is connected with top cover and the locking device that matches, it is characterized in that: locking device is, microswitch is housed on installing plate, two guide pin bushings are housed on shell, one torsion spring and latch segment and sleeve are mounted to one and are contained on the guide pin bushing, another torsion spring and movable block are installed on another guide pin bushing, pull bar is mobilizable the connection with an end of latch segment, and an end of movable block can touch microswitch, and movable block can touch latch segment.
The utility model can make the top cover of centrifuge automatically open and locking, matches with correspondent control circuits can possess top cover and do not fasten the interlock function that can not start centrifuge, and flexible movements, safe and reliable.
Fig. 1 is the structural representation of the utility model one embodiment
Fig. 2 is the locking device side view among Fig. 1
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises top cover 2, installing plate 14, be contained in the shell 6 on the installing plate 14, electromagnet 3 and pull bar 4, gate stop 1 that is connected with top cover 2 and the locking device that matches, it is different from prior art: locking device is, microswitch 5 is housed on installing plate 14, two guide pin bushings 11 are housed on shell 6, one torsion spring 7 and latch segment 9 are mounted to one with sleeve 8, and be contained on the guide pin bushing 11, another torsion spring 12 and movable block 10 are installed on another guide pin bushing 11, pull bar 4 is mobilizable the connection with an end of latch segment 9, and microswitch 5 can be touched in the lower end of movable block 10, and movable block 10 can touch latch segment 9; Be provided with two circular holes in an embodiment in the both sides of shell 6, two guide pin bushings 11 are installed in two circular hole places respectively, torsion spring 7 and latch segment 9 are mounted to one with sleeve 8, be contained on the guide pin bushing 11 in shell 6 left sides, torsion spring 12 and movable block 10 are installed on the guide pin bushing 11 on shell 6 right sides, for dustproof, on shell 6, adorn a bonnet 13, latch segment 9 has a feeler, there is a breach in movable block 10 left sides, and the feeler of latch segment 9 can touch the breach lower end in movable block 10 left sides, also establish a feeler in the lower end of movable block 10, this feeler can touch the button on the microswitch 5, establishes an aperture in the lower end of gate stop.
Dynamic process of the present utility model is; when top cover closes down; gate stop pushes up the breach lower end, left side of movable block; cause movable block to be rotated counterclockwise around guide pin bushing; the upper end breach of movable block slides in the aperture of gate stop lower end; torsion spring 7 drive latch segments compress the breach lower end, left side of movable block; make top cover locking; simultaneously the feeler of movable block is pushed down microswitch, makes the control circuit that matches possess top cover and does not fasten the defencive function that can not open top cover in the time of can not starting centrifuge and running, just can open top cover after centrifuge to stop operating; guaranteed operating personnel's safety; when needs are opened top cover, connect power supply, make electromagnet hold pull bar toward moving left; pull bar drives latch segment and rotates around guide pin bushing; latch segment and movable block are unclamped, and torsion spring 12 drives movable block and turns clockwise around guide pin bushing, causes gate stop to slip off; top cover can be opened; the feeler of movable block lower end unclamps the button of microswitch simultaneously, and top cover is opened, and causes centrifuge not turn round.
