Abstract

The utility model relates to a laboratory stirring device, belonging to the technical field of experimental instruments. The laboratory stirring device, in which a belt wheel transmission is adopted between an electric motor and a stirring rod, a rubber shockproof bracket is adopted to fix the bearing of the stirring rod, and stirring blades and the stirring rod adopt a quick-connecting chuck structure, has the advantages of stable rotation, and convenience and quickness of blade replacement, etc., and overcomes the defects of the existing stirring device of unstable rotation, large vibration and ease of looseness of the stirring blades; the utility model is suitable for various laboratories.

Description

Laboratory agitator

The utility model relates to a kind of laboratory and stirs instrument, belongs to the laboratory apparatus technical field.

Instrument is stirred in the current experiments chamber, and puddler adopts coaxial the connection with motor, paddle and puddler bolting, and there is following shortcoming in this structure:

One, the coaxial interlock rotation of motor and puddler, concentricity is poor, swing is big, make easily to be stirred that liquid is shallow to be gone out, and noise is big;

Two, the fixed-use bolt corrosion-vulnerable of paddle and puddler when particularly stirring perishable liquid, is corroded very soon, changes difficulty.

The purpose of this utility model provides the novel easily laboratory of a kind of stability of rotation, blade exchanging and stirs instrument.

This laboratory stirring instrument partly is made up of motor, puddler, stirring vane etc., and feature of the present utility model is:

One, adopts pulley transmission structure between puddler and the motor, be installed on the stainless steel strut in the nose shell; Two spring bearings of puddler are enclosed in respectively in two oil resistant rubber carriages, and a circle draw-in groove is arranged around the oil resistant rubber carriage, are separately fixed in the nose shell on two stainless steel struts by interlock;

Two, adopt quick Connection Card header structure between stirring vane and the puddler, the puddler bottom has a thickness to be slightly larger than the draw-in groove of vane thickness along axis, the puddler on draw-in groove both sides is not isometric duckbill structure, the centre of long part have one with the prismatic bayonet socket of axis normal; Stirring vane center upside has a width to be slightly larger than the rectangular indentation of puddler diameter, downside stretches out a width and puddler diameter prismatic dop quite in horizontal direction, and a pair of interval width spacing collar suitable with the puddler diameter arranged in both sides, prismatic dop top.

Instrument is stirred in the utility model laboratory, owing to adopted fixedly puddler of the shockproof carriage of rubber, has both made under very high speed conditions, rotates also very steadily, make agitator can reach the very wide range of speeds, and noise is very low; In addition, blade and puddler adopt quick Connection Card header structure, as long as blade middle part breach is inserted puddler bottom draw-in groove, blade bottom prismatic dop is stuck in the prismatic bayonet socket of puddler bottom, can firmly connect, can not become flexible, change also very quick simultaneously, overcome existing bolt type and connected corrosion-vulnerable and loosening shortcoming, be particularly suitable for the laboratory and stir perishable liquid use.

Embodiment further describes the utility model below in conjunction with accompanying drawing.

Fig. 1 is the structure chart of this stirring instrument head and puddler part, and among the figure: 1 is motor, and 2 is puddler, and 3 is belt pulley, 4 is the puddler bearing, and 5 is the oil resistant rubber bearing bracket, and 6 is the steel plate carriage, 7 is nose shell, and 8 is the head cover cap, and 9 is the rubber ring washer.

Fig. 2, Fig. 3 are the part drawing of rubber shaft bearing carriage.

Fig. 4, Fig. 5 be respectively puddler just, side view, among the figure, 10 is draw-in groove, 11 is the prismatic bayonet socket.

Fig. 6, Fig. 7 are respectively the positive side view of stirring vane, and among the figure, 12 is rectangular indentation, and 13 is the prismatic dop, and 14 is spacing collar.

Claims

1, instrument is stirred in a kind of novel laboratory, partly is made up of motor, puddler, stirring vane etc., and feature of the present utility model is: adopt pulley transmission structure between puddler and the motor, be installed on the stainless steel strut in the nose shell; Two spring bearings of puddler are enclosed in respectively in two oil resistant rubber carriages, and a circle draw-in groove is arranged around the oil resistant rubber carriage, are separately fixed in the nose shell on two stainless steel struts by interlock.

2, stir instrument according to the described laboratory of claim 1, it is characterized in that: adopt quick Connection Card header structure between stirring vane and the puddler, the puddler bottom has a thickness to be slightly larger than the draw-in groove of vane thickness along axis, the puddler on draw-in groove both sides is not isometric duckbill structure, the centre of long part have one with the prismatic bayonet socket of axis normal; Stirring vane center upside has a width and puddler diameter prismatic dop quite in horizontal direction, and a pair of interval width spacing collar suitable with the puddler diameter arranged in both sides, prismatic dop top.
