Detailed Description

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.

An apparatus 100 for putting and taking out a particle sample into and out of a round-bottomed flask according to an embodiment of the present utility model is described below with reference to fig. 1 to 9, and the apparatus 100 for putting and taking out a particle sample into and out of a round-bottomed flask includes a support member 1, a number of deforming members 2, and a net bag (not shown in the drawings). The support piece 1 is provided with a clamping part, a plurality of deformation pieces 2 are arranged around the support piece 1 at intervals, and the deformation pieces 2 have elasticity. The deformation element 2 has opposite fixed ends 21 and free ends 22 in the direction of extension thereof. The fixed end 21 is connected to the support member 1, and the free end 22 is detachably engaged with the engaging portion to switch the deforming member 2 between the free state and the deformed state. The free state of the deforming member 2 means a state in which it is not deformed, and the deformed state of the deforming member 2 means a state in which it is deformed. That is, the free end 22 can be engaged with or disengaged from the engaging portion, and the engagement or disengagement of the free end 22 with the engaging portion can cause the deforming member 2 to switch between the deformed and undeformed (free) states. Since the deforming member 2 has elasticity, the deforming portion 2 is returned to a free state when the free end 22 is disengaged from the engaging portion.

In the free state, the free end 22 is disengaged from the engagement portion, that is, the free end 22 is not subjected to the force applied by the engagement portion, so that the deformation member 2 is not deformed by the force. In the deformed state, the free end 22 is clamped with the clamping part, the deformation piece 2 is forced to bend outwards, the deformation piece 2 bends outwards in a direction away from the support piece 1, the deformation piece 2 bends to form an arc shape, and a plurality of deformation pieces 2 form a lantern-like frame structure. The net bag is connected with the deformation piece 2. In the deformed state, the net bags are expanded by the deformation pieces 2 to define a sphere-like accommodating space 3 at the inner side of the net bags, more specifically, in the free state, as the deformation pieces 2 are not subjected to bending deformation, the net bags are curled without expansion, and in the deformation process of the deformation pieces 2, the net bags which are originally curled are expanded by the deformation pieces 2, so that the sphere-like accommodating space 3 similar to the sphere is formed inside the net bags, and the sphere-like accommodating cavity of the round flask is better adapted.

When the device 100 for placing and taking out a round-bottomed flask for particle samples provided by the embodiment of the utility model is used for sampling, the deformation piece 2 is in a free state, the device 100 for placing and taking out the round-bottomed flask for particle samples stretches into the round-bottomed flask through the bottle mouth, the free end 22 of the deformation piece 2 of the device 100 for placing and taking out the round-bottomed flask for particle samples faces the bottle mouth of the round-bottomed flask, the free end 22 of the deformation piece 2 is clamped with the clamping part of the support piece 1, the deformation piece 2 is in a deformed state, the net bag is propped open by the deformation piece 2, the samples are placed in the accommodating space inside the net bag, and the sample volume is enlarged after soaking and decocting. After the decoction is completed, the free end 22 is disengaged from the engagement portion, and the apparatus 100 for introducing and removing the pellet sample into and from the round-bottomed flask can be pulled directly out of the round-bottomed flask, thereby taking out the expanded sample. The device for putting in and taking out the particle sample in the round-bottomed flask can facilitate the taking out of the sample from the round-bottomed flask, particularly facilitates the sampling process of the sample with expanded volume, can also avoid the problem that the sample is difficult to take out due to the wall hanging in the decocting process, and is particularly suitable for the sample taking out of the thin-necked round-bottomed flask.

The fixed end 21 of the deforming member 2 is connected to the bottom of the supporting member 1. In the deformed state, the middle portion of the deforming member 2 is bent to protrude to the outside away from the supporting member 1. In the free state, the deforming member 2 is adjacent to the supporting member 1, thereby facilitating the insertion or extraction of the device 100 for inserting and extracting the granular sample into or from the mouth of the round-bottomed flask along the length direction of the supporting rod 1.

Preferably, the support 1 is made of a material which is resistant to high temperature and corrosion, is hard and is not easy to deform. The deformation member 2 may be made of a material which is resistant to high temperature and corrosion, soft and flexible, and is easily restored to its original state from its bent state.

The free end 22 in the free state is located above the free end 22 in the deformed state, and it can be said that the distance between the free end 22 and the fixed end 21 in the vertical direction in the free state is larger than the distance between the free end 22 and the fixed end 21 in the vertical direction in the deformed state.
