Abstract
Description
Technical Field
[0001] This utility model relates to the field of sample preparation and grinding technology, specifically a triangular sample preparation container. Background Technology
[0002] Laboratory sample preparation machines are generally used for crushing and grinding samples, with a sample volume range of 50-500g. Their sample preparation containers are mostly cup-shaped, cylindrical in form, with cylindrical impactors or cylindrical impact rings inside. In actual use, the existing sample preparation containers are inconvenient to operate due to their overall weight, and their contact surfaces are line contact, resulting in low crushing and grinding efficiency. Therefore, to address the above problems, a triangular sample preparation container is designed to better meet the actual use needs. Utility Model Content
[0003] The purpose of this invention is to provide a triangular sample preparation container to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A triangular sample preparation container includes a lid, a ram, and a grinding jar. The lid and the grinding jar cooperate with each other, and the ram is placed inside the grinding jar. The lid and the grinding jar are mounted on a sample preparation machine and perform circular motion around a non-fixed symmetric central axis.
[0006] Preferably, a fixing ring is fixed to the upper end face of the cover, and a shock-absorbing pad is nested inside the fixing ring. The height of the shock-absorbing pad is greater than the height of the fixing ring. At the same time, the shock-absorbing pad has a circular structure. Through the contact between the shock-absorbing pad and the sample preparation machine clamping mechanism, buffering and shock absorption can be achieved during the sample preparation process, ensuring the stability of the device operation and thus effectively ensuring the grinding quality.
[0007] Preferably, the lower end face of the lid has a fixing groove, and a sealing strip is nested in the fixing groove. The sealing strip contacts the grinding jar to achieve a seal. A positioning rod is fixed on the lid. Through the sealing effect between the sealing strip and the grinding jar, the sealing between the lid and the grinding jar can be guaranteed, and the sample can be prevented from overflowing.
[0008] Preferably, the impactor is viewed from the top as an equilateral triangle and is a hollow steel block. The crushing and grinding of the sample can be achieved through the squeezing action between the impactor and the grinding jar. Furthermore, since the crushing action between the impactor and the grinding jar is surface squeezing, the crushing efficiency of the sample can be effectively guaranteed.
[0009] Preferably, the grinding jar has an equilateral triangular cavity, in which a striker is placed. The grinding jar is also equipped with a handle and a positioning hole. The positioning hole and the positioning rod are nested together. The cavity allows for the positioning of the striker, and the handle facilitates the handling of the device, improving operational convenience. The nesting between the positioning hole and the positioning rod also helps to position the grinding jar and the lid, preventing misalignment.
[0010] Preferably, the side length of the cavity is greater than the side length of the impactor, and the depth of the cavity is greater than the height of the impactor. By limiting the size of the cavity, it can be ensured that the impactor can swing inside the cavity, thereby providing a basic guarantee for the grinding of the sample and ensuring the normal operation of the device.
[0011] Preferably, the handle is symmetrically distributed about the center line of the grinding jar, and the handle is detachable from the grinding jar via a screw. The surface of the handle is provided with anti-slip texture. The detachable installation structure of the handle makes it easy to assemble and disassemble the handle, and the anti-slip texture on the surface of the handle makes it easy to grip the device.
[0012] Preferably, the grinding jar, the impactor, and the lid are all made of stainless steel, and the size of the lid, the grinding jar, and the impactor gradually decreases. By limiting the material of the grinding jar, the impactor, and the lid, the rigidity and service life of the device can be guaranteed, and by limiting the size of the lid, the grinding jar, and the impactor, the normal assembly and use of the device can be guaranteed.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This triangular sample preparation container adopts an equilateral triangular structure, which allows for surface-to-surface contact and collision during sample crushing and grinding, thereby effectively increasing the contact area. Compared with traditional line contact grinding, surface contact grinding can effectively improve crushing efficiency. After crushing, the surface structure is easy to clean, avoiding contamination between samples. In addition, the handle makes operation more convenient and simple. At the same time, the hollow structure of the impactor can effectively reduce the overall weight of the device, making the operation of the device more convenient and simple.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-3 The triangular sample preparation container provided by this utility model includes a lid 1, a ram 2 and a grinding jar 3. The lid 1 and the grinding jar 3 cooperate with each other, and the ram 2 is placed inside the grinding jar 3. The lid 1 and the grinding jar 3 are installed on the sample preparation machine and perform circular motion around a non-fixed symmetric central axis.
[0021] The grinding jar 3 has an equilateral triangular cavity 31, and a ram 2 is placed inside the cavity 31. The ram 2 is viewed from above as an equilateral triangle and is a hollow steel block.
[0022] A fixing ring 11 is fixed on the upper end face of the cover 1, and a shock-absorbing pad 12 is nested inside the fixing ring 11; a triangular fixing groove 13 is opened on the lower end face of the cover 1, and a sealing strip 14 is nested inside the fixing groove 13, and the sealing strip 14 contacts the grinding jar 3 to achieve a seal.
[0023] A handle 32 is installed on the grinding jar 3. The handle 32 is symmetrically distributed about the center line of the grinding jar 3. The handle 32 is connected to the grinding jar 3 by a screw to form a detachable structure. The surface of the handle 32 is provided with anti-slip texture.
[0024] In some specific embodiments, the height of the shock-absorbing pad 12 is greater than the height of the fixing ring 11, and the shock-absorbing pad 12 may be selected to adopt a circular structure.
[0025] In some embodiments, the grinding jar 3, the impactor 2, and the lid 1 are all made of stainless steel, and the sizes of the lid 1, the grinding jar 3, and the impactor 2 gradually decrease.
[0026] It should be noted that, in order to achieve the limiting between the lid 1 and the grinding jar 3 and prevent the lid 1 and the grinding jar 3 from shifting and affecting the sealing between the lid 1 and the grinding jar 3, the present invention can also provide a positioning rod 15 on the lid 1 and a positioning hole 33 corresponding to the positioning rod 15 on the grinding jar 3. The positioning hole 33 and the positioning rod 15 are nested together.
[0027] When using this triangular sample preparation vessel, first place the impactor 2 inside the cavity 31, and then place the sample to be ground inside the gap between the impactor 2 and the cavity 31.
[0028] After placement, nest the shock-absorbing pad 12 with the fixing ring 11, and nest the sealing strip 14 with the fixing groove 13. Then, fit the cover 1 with the grinding jar 3. Through the nesting action between the positioning rod 15 and the positioning hole 33, the positioning assembly can be achieved, so that the sealing strip 14 contacts the grinding jar 3. Finally, by holding the handle 32, assemble the entire device on the sample preparation machine. The clamping structure on the sample preparation machine contacts the shock-absorbing pad 12, thereby completing the installation of the device.
[0029] After installation, the sample preparation machine is started, and the grinding time is preset. At this time, the sample preparation machine causes the cover 1, the impactor 2, and the grinding jar 3 to perform non-symmetrical circular motion around a central axis. With the shock absorption effect of the damping pad 12, the stability of the device operation can be ensured. During the operation of the device, the impactor 2 performs non-symmetrical circular motion around a central axis in the cavity 31. With the compression of the sample by the impactor 2 and the inner wall of the grinding jar 3, the sample can be ground and broken. At this time, the impactor 2 and the inner wall of the grinding jar 3 are pressed face to face, which can effectively increase the contact area with the sample, thereby effectively improving the grinding efficiency. During the grinding process, the positioning rod 15 and the positioning hole 33 can prevent the cover 1 and the grinding jar 3 from shifting during the sample preparation process, which would affect the sealing between the cover 1 and the grinding jar 3. After grinding, the entire device is removed from the sample preparation machine, and the cover 1 and the grinding jar 3 are separated. Most of the sample is stored in the cavity 31. When removing the impactor 2, the sample adhering to the surface of the impactor 2 can be cleaned and collected by brushing.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
