Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Volumetric flask fixing device suitable for water bath as figure 1, including location flat 1, be convenient for realize placing the location in the water bath, its distinctive and local lies in: a plurality of positioning holes 2 are formed in the positioning flat plate 1, and clamping assemblies are arranged in the positioning holes 2. Like this, the volumetric flask can wear to establish in locating hole 2 and realize effectual location through the centre gripping subassembly, guarantees not to receive the buoyancy of water to appear floating and influence the whole heating effect. Simultaneously, consider that conventional volumetric flask specification is more, in order to realize the fixed of more laminating, the centre gripping subassembly of adoption is connected with on the fixed column 3 and presss from both sides body 4 including fixed column 3. In this way, for volumetric flasks with a smaller diameter, an auxiliary secondary positioning can be achieved by means of the clamping assembly. To the volumetric flask of major diameter, can take off centre gripping subassembly, directly realize the location restriction with locating hole 2. During manufacturing, the positioning holes 2 can be selected from different specifications to meet different volumetric flasks.

In view of the preferred embodiment of the present invention, the positioning hole 2 is a circular hole, and the inner wall of the positioning hole 2 is provided with the anti-slip washer 6, in consideration of the bottleneck structure of the conventional volumetric flask. In this way, a stable positioning is achieved after the volumetric flask is inserted into the positioning hole 2. Specifically, the anti-skidding gasket 6 is including the packing ring body, and the bottom surface of packing ring body is provided with pastes the layer, can directly combine through pasting layer and locating hole 2 inner wall. Simultaneously, the top surface of packing ring body is provided with anti-skidding stripe or anti-skidding granule. Like this, through anti-skidding stripe or anti-skidding granule and volumetric flask contact, realize better anti-skidding location, can not cause the unexpected pine of volumetric flask to take off.

Further see, in order to realize the installation and the taking off of the convenient of centre gripping subassembly to adapt to the location of the volumetric flask of different types, the utility model discloses be provided with the screw thread at the both ends of fixed column 3. Meanwhile, corresponding threaded holes are formed in the clamp body 4 and the positioning holes 2. Like this, fixed column 3 with press from both sides 4 threaded connection, fixed

column

3 and 2 screw holes in locating hole. When the device is adapted, a user can conveniently and rapidly adjust the device without tools.

Simultaneously, in order to realize stable centre gripping location to less tiny volumetric flask, the clamp body 4 of adoption be the U-shaped clamp, and the both ends of U-shaped clamp all are provided with limit structure, and limit structure is circular protruding 5. Therefore, the bottle mouth of the volumetric flask can be smoothly clamped and can not be easily loosened. The U-shaped clamp can be made of plastic materials during manufacturing, and has good deformation capacity.

Still further, in order to realize the stable placement of the positioning plate 1 in the volumetric flask and ensure the realization of sufficient water bath heating of the solution in the volumetric flask, an auxiliary positioning assembly 7 may be disposed on the positioning plate 1. In particular, considering the size of the volumetric flask, the auxiliary positioning assembly 7 can be constituted by a bracket or a hook, so that the positioning plate 1 does not shake due to water impact during actual use. And, in order to avoid there may be sharp-pointed part and fish tail operating personnel during the use, the utility model discloses a dull and stereotyped 1's of location edge distribution has circular arc chamfer. Furthermore, the positioning flat plate 1 can be made of plastic or metal materials, can adapt to different water bath kettle sizes, and replaces the function of a water bath kettle cover.
