The drives structure of vacuum sterilizer cabinet door
Technical field
The present invention relates to vacuum sterilizer, refer more particularly to the drives structure of vacuum sterilizer cabinet door.
Background technology
The mode of the opening and closing of vacuum sterilizer cabinet door is a lot, wherein: moving up and down of cabinet door is one of mode of cabinet door opening and closing.The drives structure of at present conventional vacuum sterilizer cabinet door is: in the left and right sides of cabinet, be respectively arranged with the slot type guide rail matching with the upper and lower slip of cabinet door, on the arranged on left and right sides edge of cabinet door, be respectively arranged with roller, in order to reduce resistance to sliding, above cabinet, be provided with synchronizing shaft, synchronizing shaft is driven by motor, the two ends of described synchronizing shaft are provided with take up roll, on take up roll, be wound with steel wire rope or driving chain, described steel wire rope or driving chain are connected with cabinet door arranged on left and right sides edge.
During the unlatching of vacuum sterilizer cabinet door, motor drives synchronizing shaft to rotate, and drives the take up roll at synchronizing shaft two ends to rotate, and the rolling thereby drive steel wire rope or driving chain make progress, drives door of steam sterilization cabinet upward sliding until open completely; When vacuum sterilizer cabinet door is closed, motor drives synchronizing shaft to rotate backward, and drives the take up roll at synchronizing shaft two ends to rotate backward, thereby discharges steel wire rope or driving chain downwards, drives door of steam sterilization cabinet down sliding until close completely.The shortcoming that the drives structure of above-mentioned vacuum sterilizer cabinet door exists is: drives structure is large and heavy, energy consumption is high, noise is large.
Summary of the invention
The object of this invention is to provide that a kind of energy consumption is low, noise is little, cabinet door the slides drives structure of vacuum sterilizer cabinet door stably.
For achieving the above object, the present invention has adopted following technical scheme.
The drives structure of vacuum sterilizer cabinet door, comprise cabinet, in the left and right sides of cabinet, be respectively arranged with the guide rail matching with the upper and lower slip of cabinet door, be characterized in: the driving device that is respectively arranged with cabinet door in the left and right sides at cabinet top, the driving device of described cabinet door is: the mounting bracket that is fixed on cabinet top, on mounting bracket, be provided with motor, on the output shaft of motor, drive sprocket is installed, on drive sprocket, be provided with driving chain, one end of driving chain is connected with cabinet door, and the other end of driving chain is connected with balance weight.
Further, the drives structure of aforesaid vacuum sterilizer cabinet door, wherein: described driving chain is connected with cabinet door by carriage, the structure of described carriage is: be arranged on the holder on cabinet door, in holder, be provided with coupling spindle, one end of coupling spindle is connected with driving chain, on described connecting axle, is provided with pulley, and described pulley slides in guide rail.
The invention has the beneficial effects as follows: in the upper and lower sliding process of cabinet door, the weight of balance weight balancing tank door, motor drives the resistance that only need overcome the motion of cabinet door, and motor driving power is little, energy consumption is low, noise is little; In the left and right sides at cabinet top, be respectively arranged with the driving device of cabinet door, drive separately, compact conformation, easy for installation, system little, the low cost of manufacture that takes up room; When motor overload, bi-motor tends to be balanced, and makes cabinet door slide balance, can eliminate the jitter phenomenon of cabinet door.

The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the drives structure of vacuum sterilizer cabinet door of the present invention is further described.
Referring to Fig. 1, shown in Fig. 2, the drives structure of vacuum sterilizer cabinet door of the present invention comprises cabinet 10, cabinet 10 left sides be provided with cabinet door 8 on, the guide rail 2 that lower slider matches, cabinet 10 right sides be provided with cabinet door 8 on, the guide rail 21 that lower slider matches, concrete fit system between cabinet door and guide rail is: cabinet door 8 both sides have the chimb of protrusion, put in guide rail 2 and guide rail 21, and cabinet door 8 is slided up and down along guide rail 2 and 21, in cabinet 10 upper ends, left side, be provided with the left side driving device of cabinet door, the left side driving device of described cabinet door is: the mounting bracket 7 that is fixed on cabinet 10 tops, on mounting bracket 7, be provided with motor 9, drive sprocket 6 is installed on the output shaft of motor 9, on drive sprocket 6, be provided with driving chain 5, one end of driving chain 5 is connected with balance weight 3, the other end of driving chain 5 is connected by the carriage 4 in left side and the lower end, left side of cabinet door 8, shown in Figure 3, the structure of the carriage 4 in described left side is: comprise the holder 44 being arranged on cabinet door 8, in holder 44, be provided with coupling spindle 42, one end of coupling spindle 42 is connected with one end of driving chain 5, on described connecting axle 42, be provided with pulley 43, described pulley 43 slides in guide rail 2, in cabinet 10 upper ends, right side, be provided with the right driving device of cabinet door, the right driving device of described cabinet door is: comprise the mounting bracket 71 that is fixed on cabinet 10 tops, on mounting bracket 71, be provided with motor 91, drive sprocket 61 is installed on the output shaft of motor 91, on drive sprocket 61, be provided with driving chain 51, one end of driving chain 51 is connected with balance weight 31, the other end of driving chain 51 is connected by the carriage 41 on right side and the lower end, right side of cabinet door 8, shown in Figure 4, the structure of the carriage 41 on described right side is: be arranged on the holder 414 on cabinet door 8, in holder 414, be provided with coupling spindle 412, one end of coupling spindle 412 is connected with one end of driving chain 51, on described connecting axle 412, be provided with pulley 413, described pulley 413 slides in guide rail 21.
When vacuum sterilizer cabinet door 8 needs to open, motor 9 drives drive sprocket 6 to rotate counterclockwise, thereby drives driving chain 5 to rotate counterclockwise, and the pulley 43 on the coupling spindle 42 being connected with driving chain 5 is along guide rail 2 upward slidings; Motor 91 drives drive sprocket 61 to clockwise rotate simultaneously, thereby drive driving chain 51 to clockwise rotate, pulley 413 on the coupling spindle 412 being connected with driving chain 51, along guide rail 21 upward slidings, drives door of steam sterilization cabinet 8 upward slidings together until open completely---and its state is shown in Figure 1; When vacuum sterilizer cabinet door 8 need be closed, motor 9 drives drive sprocket 6 to rotate backward, thereby drives driving chain 5 to clockwise rotate, and the pulley 43 on the coupling spindle 42 being connected with driving chain 5 is along guide rail 2 down slidings; Motor 91 drives drive sprocket 61 to rotate backward simultaneously, thereby drives driving chain 51 to rotate counterclockwise, and the pulley 413 on the coupling spindle 412 being connected with driving chain 51, along guide rail 21 down slidings, drives door of steam sterilization cabinet 8 down slidings until close completely together.
Use the drives structure of vacuum sterilizer cabinet door of the present invention, in the upper and lower sliding process of cabinet door, the weight of balance weight balancing tank door, motor drives the resistance that only need overcome the motion of cabinet door, and motor driving power is little, energy consumption is low, noise is little; In the left and right sides of cabinet upper end, be respectively arranged with the driving device of cabinet door, drive separately, compact conformation, easy for installation, system little, the low cost of manufacture that takes up room; When motor overload, bi-motor tends to be balanced, and makes cabinet door slide balance, can eliminate the jitter phenomenon of cabinet door.
