Description

Technical Field

[0001] The utility model relates to the technical field of sample distribution, in particular to a weighing tool for viscous samples. Background Art

[0002] Sample allocation is an important part of the sample management process. It involves allocating samples to different testing departments, researchers or experimental projects according to certain rules or requirements. After the samples are allocated, they need to be weighed and recorded, so weighing tools are used.

[0003] However, some viscous samples are sticky. During the sampling process, ordinary tools are often unable to overcome the stickiness, resulting in the inability to directly obtain samples of appropriate volume. Moreover, due to the stickiness, the samples will still adhere to the weighing tool after the weighing record is completed. If they cannot be cleaned in time, the accuracy of subsequent sample weighing data will be affected. Therefore, a weighing tool for viscous samples is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a weighing tool for viscous samples, which has the advantages of auxiliary weighing and ensuring the accuracy of data, and solves the problem that the structure of existing weighing tools needs to be optimized.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a weighing tool for viscous samples, comprising a base plate, a weighing device fixedly mounted on the top of the base plate, a support column fixedly mounted on the top of the base plate, and an auxiliary weighing device provided on the outside of the base plate;

[0006] The support column is movably connected to a piston sleeve inside, a first telescopic rod is fixedly installed on the inner left wall of the piston sleeve, an electric slide rail is provided on the outside of the support column, a sample barrel is provided on the outside of the electric slide rail, a second telescopic rod is provided on the outside of the bottom plate, a scraper is fixedly installed on the bottom of the second telescopic rod, a supporting plate is fixedly installed on the top of the weighing device, and a container is movably connected to the top of the supporting plate.

[0007] Furthermore, a first limiting ring is fixedly installed on the outside of the piston sleeve, and two bolts are fixedly installed on the right side of the first limiting ring. The outsides of the two bolts are threadedly connected with nuts, and a first through hole is provided inside the support column to match the two bolts. The piston sleeve is movably connected to the piston column, the right side of the first telescopic rod is fixedly connected to the left side of the piston column, and a discharge port is provided on the right side of the piston sleeve.

[0008] Furthermore, two limit blocks are fixedly installed on the outside of the support column, a rotating rod is movably connected to the outside of the support column, a mounting block is fixedly installed on the right side of the rotating rod, the upper and lower sides of the electric slide rail are fixedly connected to the inside of the mounting block, and the outer surface of the electric slide rail is slidably connected to a lifting block.

[0009] Furthermore, a second through hole adapted to the sample barrel is provided inside the lifting block, a second limiting ring is fixedly installed on the outer surface of the sample barrel, the interior of the second through hole and the outer surface of the sample barrel are both provided with matching threaded rings, a valve discharge pipe is fixedly installed on the bottom of the sample barrel, and a feed port adapted to the valve discharge pipe is provided on the top of the piston sleeve.

[0010] Furthermore, a top plate is fixedly installed on the top of the support column, the bottom of the top plate is fixedly connected to the top of the second telescopic rod, the left side of the scraper is fitted with the right side of the piston sleeve, and a third limiting ring is fixedly installed on the outer surface of the container.

[0011] Furthermore, four auxiliary rods are fixedly installed inside the supporting plate, and the outsides of the four auxiliary rods are all sleeved with spring bodies. The outsides of the four auxiliary rods are all slidably connected with L-shaped plates, and the outer surfaces of the L-shaped plates are movably connected to the outer surface of the third limiting ring. The four spring bodies are fixedly installed between the outsides of the four L-shaped plates and the inside of the third limiting ring.

[0012] Beneficial effects

[0013] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0014] The weighing tool for viscous samples first rotates the rotating rod, and then fixes the sample barrel inside the lifting block through the threaded ring. When the rotating rod is rotated again, the valve discharge pipe is aligned with the feed port of the piston sleeve, and then the electric slide is started to drive the lifting block and the sample barrel to move downward, so that the valve discharge pipe is inserted into the feed port, and then the valve discharge pipe is controlled to feed into the piston sleeve. Then, the piston column is driven to move by the first telescopic rod to squeeze out the sample inside the piston sleeve, and then the sample volume in the container is observed. After reaching the appropriate volume, the second telescopic rod and the scraper can be used to scrape off the sample remaining at the discharge port and block the discharge port. Then, the sample in the container can be weighed and recorded by the scale, and then the L-shaped plate can be pulled to cancel the limit of the third limit ring, so that the container can be removed from the carrying plate, and the weighed sample is sent to the subsequent testing process. The container is then cleaned to avoid affecting the subsequent weighing data, thereby achieving the purpose of auxiliary weighing and ensuring the accuracy of the data.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0021] See also Figure 1-4 A weighing tool for viscous samples includes a base plate 1, a weighing device 2 is fixedly installed on the top of the base plate 1, a support column 3 is fixedly installed on the top of the base plate 1, and an auxiliary weighing device 4 is provided on the outside of the base plate 1;

[0022] The support column 3 is movably connected to the piston sleeve 401, and the inner left wall of the piston sleeve 401 is fixedly installed with a first telescopic rod 402. The support column 3 is provided with an electric slide rail 403 on the outside, and a sample barrel 404 is provided on the outside of the electric slide rail 403. The second telescopic rod 405 is provided on the outside of the base plate 1, and a scraper 406 is fixedly installed on the bottom of the second telescopic rod 405. The top of the weighing device 2 is fixedly installed with a supporting plate 407, and the top of the supporting plate 407 is movably connected to a container 408.

[0023] Specifically, such as Figure 1 As shown, remove the nut on the bolt, then pull the piston sleeve 401 to pull the piston sleeve 401 out from the interior of the support column 3, and then clean or maintain the piston sleeve 401 separately. After the cleaning and maintenance are completed, reinsert the piston sleeve 401 into the interior of the support column 3 and re-secure it with the bolts and nuts.

[0024] Specifically, such as Figure 1As shown, open the electric slide rail 403 to drive the lifting block to rise, and then the valve discharge pipe at the bottom of the sample barrel 404 can be pulled out from the feed port, and then the rotating rod is rotated to rotate the sample barrel 404 out of the device. Then, the sample barrel 404 can be rotated to remove the sample barrel 404 from the second through hole inside the lifting block through the threaded ring to clean or replace the sample barrel 404. After completion, repeat the above operations to complete the installation.

[0025] Specifically, such as Figure 2 As shown, by pulling the L-shaped plate, it can move along the outer surface of the auxiliary rod and squeeze the spring body, thereby canceling the fixation of the third limiting ring on the outer surface of the container 408. Then, when the container 408 is cleaned, the L-shaped plate is released. Under the action of the spring body, the L-shaped plate can be fixed along the auxiliary rod to the third limiting ring, thereby preventing the container 408 from falling from the top of the weighing device 2 due to accidental external contact during the weighing process.

[0026] During implementation, follow these steps:

[0027] 1) First, pull the L-shaped plate so that it compresses the spring body along the auxiliary rod, then place the container 408 on the supporting plate 407, and then release the L-shaped plate. The spring body and the L-shaped plate can be used to fix the container in place.

[0028] 2) Then insert the piston sleeve 401 into the support column 3 and secure it with bolts and nuts;

[0029] 3) The sample barrel 404 is then installed inside the lifting block using the threaded ring, and is driven down by the electric slide rail 403 so that the valve discharge pipe is inserted into the feed port;

[0030] 4) Finally, open the first telescopic rod 402 and cooperate with the piston column to squeeze the sample into the piston sleeve 401, and use the second telescopic rod 405 and the scraper 406 to hang up the residual sample at the discharge port and block it, and then weigh it through the weighing device 2.

[0031] In summary, the weighing tool for the viscous sample first rotates the rotating rod, and then fixes the sample barrel 404 to the inside of the lifting block through the threaded ring. Then, when the rotating rod is rotated again, the valve discharge pipe is aligned with the feed port of the piston sleeve 401, and then the electric slide 403 is started to drive the lifting block and the sample barrel 404 to move downward, so that the valve discharge pipe is inserted into the feed port, and then the valve discharge pipe is controlled to feed the piston sleeve 401, and then the piston column is driven to move by the first telescopic rod 402, so that the sample inside the piston sleeve 401 is squeezed out, and then the container 408 is observed. The sample volume in the container 408 reaches the appropriate volume. The second telescopic rod 405 and the scraper 406 can be used to scrape off the sample remaining at the discharge port and block the discharge port. Then, the weighing device 2 can be used to weigh and record the sample in the container 408. Then, the L-shaped plate can be pulled to cancel the limit of the third limit ring, so that the container 408 can be removed from the carrying plate 407, and the weighed sample can be sent to the subsequent testing process. Then, the container 408 is cleaned to avoid affecting the subsequent weighing data, thereby achieving the purpose of auxiliary weighing and ensuring the accuracy of the data.
