< example >
FIG. 1 is a schematic perspective view of a flask upright applicator in an extended state of a locking unit according to an embodiment of the present invention.
As shown in fig. 1, in the present embodiment, a flask vertical placing device 100 is used to stably place a flask in a pot body (not shown) of a water bath, and one water bath may be provided with one or more flask placing mechanisms 100 according to actual needs; in this example, an Erlenmeyer flask is used as an example for explanation. The flask upright applicator 100 comprises an applicator base 10 and a locking unit 20.
Fig. 2 is a schematic perspective view of a placement base according to an embodiment of the invention.
As shown in fig. 1 and 2, the placing base 10 is used for installing the locking unit 20 and supporting the flask, and the bottom of the placing base can be attached to the bottom wall of the pot body. The central part of the placing seat 10 is provided with a supporting part 11 matched with the bottom of the flask for supporting the flask.
In this embodiment, the placing seat 10 is a circular seat, the supporting portion 11 is a circular supporting ring integrally formed at the edge of the central hole of the placing seat 10 and protruding upward, the upper end surface of the circular supporting ring has m supporting grooves 11a arranged at equal intervals, and m is a positive integer not less than 2. In this example, m is 4.
Fig. 3 is a schematic perspective view of a locking unit in an embodiment of the present invention.
As shown in fig. 1 and 3, a locking unit 20 is provided on the placing base 10 for locking the flask when the flask is placed on the receiver 11. The locking unit 20 comprises m locking blocks 21 and m flipping arms 22.
The m locking blocks 21 are independent from each other and are arranged at intervals along the circumferential direction of the supporting part 11, and the space surrounded by all the locking blocks 21 is formed into a placing cavity 20A for placing the flask. The gap between two adjacent locking blocks 21 is set as a locking block gap 21A.
The lower end of each locking block 21 is rotatably connected with the placing seat 10. In this embodiment, the rotation fulcrum between the locking block 21 and the placing seat 10 is located inside the corresponding locking block 21, that is, the rotation shaft 211 between the locking block 21 and the placing seat 10 is located inside the corresponding locking block 21, two ends of the rotation shaft 211 are respectively fixed on the placing seat 10 through the mounting blocks 211a, the lower end of the locking block 21 is provided with a connecting block 212, and the connecting block 212 has a shaft hole 212a for the rotation shaft 211 to pass through.
The inner side wall of the locking block 21 has a shape matching the shape of the lower end of the flask. In this embodiment, the locking blocks 21 are hollow, and two water inlet holes 213 are formed at the top of each locking block 21.
The m turnover arms 22 correspond to the m locking blocks 21 one by one and correspond to the m bearing grooves 11a one by one. The outer end of each turnover arm 22 is fixedly connected with the connecting block 212 of the corresponding locking block 21, and the inner end extends towards the inner side direction of the supporting part 11. In the present embodiment, the invert arm 22 extends inward in the radial direction of the receiver 11. After the flask is placed in the placing cavity 20A, each turnover arm 22 is turned over downwards under the action of the gravity of the flask, so that the corresponding locking block 21 is driven to turn over inwards, the inner wall of the locking block 21 is pressed on the side wall of the flask, and the flask is locked.
Fig. 4 is a schematic perspective view of a locking unit of a flask upright placing device in the embodiment of the invention.
In this example, the operation of the flask stand-up applicator 100 is:
with the locking unit 20 in the unfolded state as shown in fig. 1, the flask is placed in the placing chamber 20A. After the bottom wall of the flask is contacted with the turnover arms 22, all the turnover arms 22 are gradually turned downwards under the action of the gravity of the flask, and then the corresponding locking blocks 21 are respectively driven to be gradually turned inwards until the inner end parts of the turnover arms 22 are contacted with the bottom wall of the corresponding bearing grooves 11a, and the locking unit 20 is in a locking state as shown in fig. 4; at this time, the inner wall of the locking block 21 is pressed against the side wall of the flask, thereby achieving locking of the flask in an upright state.
Since the rotation fulcrum of the locking block 21 and the placing base 10 is located at the inner side of the locking block 21, once the flask is taken out upward, the locking block 21 is automatically turned outward, and at the same time, the turning arm 22 is turned upward, so that the locking unit 20 is returned to the unfolded state as shown in fig. 1.
Effects and effects of the embodiments
According to the flask vertical placer and the water bath pot comprising the flask vertical placer, the locking unit comprises m locking blocks which are mutually independent and are arranged at intervals along the circumference of the supporting part of the placing seat and m turnover arms which correspond to the m locking blocks one by one, the lower end part of each locking block is rotatably connected with the placing seat, a space surrounded by all the locking blocks is formed into a placing cavity for placing the flask, one end part of each turnover arm is fixedly connected with the lower end part of the corresponding locking block, and the other end part of each turnover arm extends towards the inner side direction of the supporting part.
In addition, because the inside wall of latch segment has the shape assorted shape with the shape of flask for the latch segment can closely laminate with the lateral wall of flask, has further improved the locking effect of flask, also is difficult for causing the damage to the flask.
In addition, because the locking block is of a hollow structure, the top of the locking block is provided with at least one water inlet hole, heated water in the pot body can enter the cavity of the locking block, the locking block is increased in weight and sinks to the bottom of the water, and the placing seat is tightly attached to the bottom wall of the pot body, so that the flask can be stabilized; meanwhile, the heating uniformity of the flask is also improved.
