Description

Technical Field

[0001] The utility model relates to the field of sample cleaning, in particular to a bracket for cleaning a sample beaker. Background Art

[0002] In scientific research, specimens are samples used for experiments or measurements. Different experimental methods have different requirements for the sample state of the specimens. For chemical analysis methods of metal materials, the sample states mainly include chips, blocks, columns, etc. Usually, sample preparation is to obtain specimens from large samples according to requirements through machining. These specimens need to be representative so that they can accurately reflect the properties of the entire substance. The main machining methods include lathes, milling machines, drilling machines, etc. to prepare chip samples, and wire cutting to prepare round rods or long strip samples. However, some impurities will be introduced into the specimen during the machining process. For example, when using a lathe to prepare magnesium alloy chip samples, the cutter head will introduce iron contamination, resulting in a high iron result. If the sample preparation process is not strictly controlled, it will also affect the determination of trace elements such as calcium, magnesium, boron, lead, etc., and if the stains during turning and milling are not cleaned, it will also affect the determination of carbon, sulfur, oxygen, and nitrogen. Therefore, in many cases, the sample needs to be cleaned to meet daily testing. The methods for cleaning the sample include acid pickling, organic reagent cleaning, etc.

[0003] The main tool for cleaning samples is a beaker. Taking organic reagent cleaning as an example, put an appropriate amount of sample into a 200mL beaker, add 20ml of first-grade water, pour out the water, add 10ml of ethanol, repeat twice, and blow dry with cold air from a blower.

[0004] In current sample cleaning methods, when the cleaning agent in the beaker is poured out, the sample may be accidentally poured out, resulting in sample loss. This increases sample processing time, wastes time and labor, and reduces test efficiency.

[0005] To this end, this case proposes a sample cleaning beaker holder to solve the problem of pouring out the sample when pouring the cleaning agent. Utility Model Content

[0006] The main purpose of this utility model is to provide a sample cleaning beaker holder that can effectively solve the technical problem in the prior art that when the cleaning agent in the beaker is poured out, the sample is accidentally poured out with it, resulting in sample loss. This increases sample processing time, wastes time and labor, and reduces testing efficiency.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A sample cleaning beaker support comprises a base, one end of the base is connected to a head via two screws, the head and the base form a rectangular structure, and a limiting structure is provided on the inner side of the base;

[0009] The limiting structure includes a slide groove, which is opened on the inner wall of the base, and the first slide bar and the second slide bar are symmetrically slidably connected inside the slide groove. Two clamping columns are fixedly installed on the upper parts of the first slide bar and the second slide bar. A reinforcing rod is fixedly installed at the inner center position of the base, and a bidirectional screw is passed through the head, the first slide bar, the reinforcing rod, the second slide bar and the base. The bidirectional screw is rotatably connected to the head, the reinforcing rod and the base, and the threads in two directions of the bidirectional screw are respectively threadedly connected to the first slide bar and the second slide bar.

[0010] As a further solution of the present invention, a height adaptation structure is provided on the upper part of the base, and the height adaptation structure includes two fixed columns, which are symmetrically installed on the upper part of the base, and the top ends of the two fixed columns are penetrated by movable columns, and the top ends of the two movable columns are installed with ball heads through bolts.

[0011] As a further solution of the present invention, a reinforcing rib is connected between the two fixed columns, the bottom of the fixed column is threadedly connected to the bottom cover, the bottom cover and the base are connected by bolts, the bottom end of the movable column is provided with a limiting plate, and the inner wall of the fixed column is provided with a limiting step near the top, the limiting step and the limiting plate form a vertical upward limit, and a spring is fixedly connected between the limiting plate and the bottom cover.

[0012] As a further solution of the present invention, a sealing structure is provided between the two ball heads, and the sealing structure includes a rotating rod, which is inserted between the two ball heads, and a pressure plate and a pressure rod are symmetrically installed on the outside of the rotating rod, the pressure rod is welded to the rotating rod, and the pressure plate and the rotating rod are slidingly connected, and a filter is fixed to the bottom of the pressure rod by screws.

[0013] As a further solution of the present invention, two pressure rods are symmetrically arranged, two arc bars are fixedly connected between the two pressure rods, and screws pass through the filter mesh and are threadedly connected to the arc bars.

[0014] As a further solution of the present invention, knobs are fixedly installed on both ends of the bidirectional screw, and the top surfaces of the first slide bar and the second slide bar are flush with the top surface of the base.

[0015] As a further solution of the present invention, a through groove is provided at the connection between the rotating rod and the pressure plate, and the through groove is connected to the outside of one of the ball heads.

[0016] The beneficial effects of the utility model are as follows:

[0017] By setting a limiting structure, the beaker can be easily fixed, and since the first slide bar and the second slide bar are movable, beakers of different diameters can be fixed, and the application range is wide. Secondly, since two clamping columns are provided on the upper part of the first slide bar and the second slide bar, the four clamping columns facilitate stabilizing the cylindrical beaker, and the stability is higher.

[0018] By setting up a height adaptation structure, on the one hand, it can adapt to the height of different beakers and has a wide range of uses. On the other hand, the contraction force of the spring can always press the filter screen tightly at the cup mouth of the beaker, ensuring the stability of the filter screen connection;

[0019] By setting a sealing structure in conjunction with a limiting structure and a height adaptation structure, the problem of samples falling due to pouring out the cleaning agent during the traditional beaker cleaning process is effectively solved. There is no need to manually remove the sample, and the filter is pressed against the mouth of the beaker by the spring contraction force, without the need for manual force to press the filter, which is more practical and convenient. After the sample is placed inside the beaker, it is convenient to frequently pour it out through the filter and add cleaning agent or water, which is more convenient to use.

DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] Combine Figure 1-Figure 7 A sample cleaning beaker bracket includes a base 1, one end of the base 1 is connected to a head 2 by two screws, the head 2 and the base 1 form a rectangular structure, and a limiting structure 3 is provided on the inner side of the base 1.

[0031] See Figure 1 and Figure 5 , it is further obtained that the limiting structure 3 includes a slide groove 4, the slide groove 4 is opened on the inner wall of the base 1, and the interior of the slide groove 4 is symmetrically slidably connected with a first slide bar 5 and a second slide bar 6, and the upper parts of the first slide bar 5 and the second slide bar 6 are fixedly installed with two clamping columns 7, a reinforcing rod is fixedly installed at the inner center position of the base 1, and a bidirectional screw 8 is passed through the head 2, the first slide bar 5, the reinforcing rod, the second slide bar 6, and the base 1, the bidirectional screw 8 is rotatably connected to the head 2, the reinforcing rod, and the base 1, and the threads of the bidirectional screw 8 in two directions are threadedly connected to the first slide bar 5 and the second slide bar 6 respectively, and knobs are fixedly installed at both ends of the bidirectional screw 8, and the top surfaces of the first slide bar 5 and the second slide bar 6 are flush with the top surface of the base 1.

[0032] Specifically, when the beaker is placed on the upper part of the base 1, the bidirectional screw 8 is rotated by the knob, and the bidirectional screw 8 simultaneously drives the first slide bar 5 and the second slide bar 6 to move in opposite or relative directions, thereby driving the two sets of clamping columns 7 to move. The two sets of clamping columns 7 can clamp and fix the beaker, which can effectively limit and fix the beaker to ensure that the beaker is not easy to fall off the base 1.

[0033] Example 2

[0034] See Figure 4, and on the basis of Example 1, it is further obtained that the upper part of the base 1 is provided with a height adaptation structure 9, the height adaptation structure 9 includes two fixed columns 10, the two fixed columns 10 are symmetrically installed on the upper part of the base 1, and the tops of the two fixed columns 10 are penetrated by a movable column 11, the tops of the two movable columns 11 are installed with ball heads 12 through bolts, and a reinforcing rib is connected between the two fixed columns 10, the bottom of the fixed column 10 is threadedly connected to the bottom cover, the bottom cover is connected to the base 1 by bolts, the bottom end of the movable column 11 is provided with a limiting plate, and the inner wall of the fixed column 10 is provided with a limiting step near the top, the limiting step and the limiting plate form a limit in a vertical upward direction, and a spring 19 is fixedly connected between the limiting plate and the bottom cover.

[0035] Specifically, when placing a flask, the two movable columns 11 can pull up the spring 19, and then the beaker is placed on the upper part of the base 1. When in use, the telescopic force of the spring 19 can make the height of the movable column 11 adjustable to adapt to beakers of different heights.

[0036] Example 3

[0037] See Figure 3 、 Figure 5 、 Figure 6 and Figure 7 , and on the basis of Example 1 and Example 2, it is further obtained that a sealing structure 13 is provided between the two ball heads 12, and the sealing structure 13 includes a rotating rod 14, the rotating rod 14 is inserted between the two ball heads 12, and a pressure plate 15 and a pressure rod 16 are symmetrically installed on the outside of the rotating rod 14, the pressure rod 16 is welded to the rotating rod 14, and the pressure plate 15 is slidingly connected to the rotating rod 14, and a filter screen 18 is fixedly installed on the bottom of the pressure rod 16 by a screw 17, and two pressure rods 16 are symmetrically arranged, and two arc bars are fixedly connected between the two pressure rods 16, the screw 17 passes through the mesh of the filter screen 18 and is threadedly connected to the arc bar, and a through groove is opened at the connection between the rotating rod 14 and the pressure plate 15, and the through groove is connected to the outside of one of the ball heads 12.

[0038] Specifically, a filter screen 18 of appropriate diameter is selected according to the caliber of the beaker, and then the screw 17 is passed through the mesh of the filter screen 18 and connected to the arc thread. The filter screen 18 and the pressure rod 16 can be pressed on the top of the beaker in conjunction with the movable column 11. When pouring the cleaning agent, the filter screen 18 can prevent the sample from falling. Moreover, the pressure rod 16 can be quickly rotated by the rotating rod 14, which is convenient for quickly removing or replacing the sample. Since there is a through groove between the rotating rod 14 and the ball head 12, when the pressure plate 15 slides between the rotating rod 14 and the ball head 12 through the through groove, it can play a limiting role, making the rotating rod 14 unable to rotate.

[0039] It should be noted that the present invention is a sample cleaning beaker support. When in use, first select a filter screen 18 of appropriate diameter according to the caliber of the beaker and install it under the pressure rod 16 through the screw 17. Then pull the pressure rod 16 to drive the movable column 11 to rise, providing space for placing the beaker.

[0040] Place the beaker on the upper part of the base 1, and then rotate the bidirectional screw 8, which drives the two sets of clamping columns 7 to move through the first slide bar 5 and the second slide bar 6, thereby clamping and fixing the beaker;

[0041] First, keep the pressure rod 16 carrying the filter 18 in a vertical state to facilitate people to put the cleaning agent and sample into the beaker. After the addition, the pressure rod 16 can be turned over so that the filter 18 covers the top of the beaker. Then, the pressure plate 15 is slid through the through groove to the connection between the rotating rod 14 and the ball head 12 to lock the rotating rod 14, so that the pressure rod 16 and the filter 18 cannot rotate. The contraction force of the spring 19 can make the filter 18 tightly pressed against the cup mouth of the beaker.

[0042] When the cleaning agent needs to be poured, hold the fixed column 10 and tilt the entire bracket to tilt the beaker, and then pour it. During the pouring process, the filter 18 blocks the sample from falling;

[0043] When the sample or beaker needs to be taken out, the pressing plate 15 is slid to the inside of the rotating rod 14 again, and then the rotating rod 14 is rotated by the pressing plate 15 to flip the filter screen 18. The bidirectional screw 8 is rotated to release the clamping force of the clamping column 7 to clamp the beaker, and the beaker can be taken out.

[0044] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
