Specifically, the apron has been placed to pot body upper end, and the slot hole has been seted up to the apron right-hand member, and the slot hole runs through to the bull stick upper end, and the bull stick upper end is fixed with the barre.

Specifically, a water discharge pipe communicated with the interior of the pot body is fixed at the lower end of the pot body, and a valve is installed on the water discharge pipe.

Specifically, a plurality of through holes are formed in the sliding plate.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses, simple structure, convenient operation, low in manufacturing cost can carry out abundant rocking to the liquid in the test tube, and liquid reaction rate in the test tube has been accelerated to the water bath in-process, can also carry out the water bath to the liquid in the beaker simultaneously, and application scope is wide.

Detailed Description

As shown in figure 1-2, a water bath kettle for a chemical laboratory comprises a kettle body 1, wherein a water discharge pipe 8 communicated with the interior of the kettle body 1 is fixed at the lower end of the kettle body 1, a valve is installed on the water discharge pipe 8, a heating element 2 is embedded and fixed on a bottom plate of the kettle body 1, transverse elongated slots 3 are respectively arranged on the front side wall and the rear side wall in the kettle body 1 above the heating element 2, a sliding plate 4 is arranged in the kettle body 1, a plurality of through holes 6 are arranged on the sliding plate 4, the front end and the rear end of the sliding plate 4 are slidably arranged in the front elongated slot and the rear elongated slot 3, the left end of the sliding plate 4 is connected with the left side wall of the kettle body 1 through a spring 7, a lifting plate 12 is slidably arranged in the vertical direction in the kettle body 1 above the sliding plate 4, the outer side wall of the lifting plate 12 is in sliding contact with the inner side wall of the kettle body 1, a plurality of fisheye joint inner rings 13 are rotatably arranged on the lifting plate 12, an arc-shaped slot 5 concentric with the fisheye joint inner rings 13 is arranged at the upper end of the

sliding plate

4, 12 left end threaded connection of lifter plate has

bolt

11, and 11 lower extremes of bolt rotate with 1 bottom plate of the pot body to be connected, and 12 right-hand members of lifter plate slide and are provided with

bull stick

9, and 9 lower extremes of bull stick rotate and set up on 1 bottom plate of the pot body, are fixed with cam 10 on the bull stick 9, and the contact of cam 10 outer fringe and 4 right-hand members of slide, apron 14 has been placed to 1 upper end of the pot body, and 14 right-hand members of apron have seted up slot hole 15, and slot hole 15 is run through to 9 upper ends of bull stick, and 9 upper ends of bull stick are fixed with barres 16.

When needs carry out the water bath to the liquid in the test tube, run through the arc wall 5 that lies in slide 4 behind the fisheye joint inner circle 13 with the test tube lower extreme, then cover 14 lid in pot body 1 upper end, and make bull stick 9 be located slot hole 15, start heating member 2 and carry out the constant temperature heating to the water of the pot body 1, carry out the in-process of constant temperature water bath to the test tube, through 16 rotation bull sticks 9 of barre, make cam 10 rotate, cam 10 pivoted process and under spring 7's elastic force effect, reciprocating motion about slide 4 in elongated slot 3, thereby can make test tube and fisheye joint inner circle 13 swing simultaneously, the in-process of test tube wobbling, the inside liquid of test tube takes place to rock, thereby can accelerate the reaction.
