Abstract
Description
Technical Field
[0001] This utility model relates to the field of density analysis instrument technology, specifically a true density analyzer that employs a detachable sample measurement chamber. Background Technology
[0002] A true density analyzer is an important instrument used to measure the true density of various materials. Its working principle is usually based on the gas displacement method, which calculates the true density of the sample by measuring the volume of gas displaced by the sample.
[0003] Most existing true density analyzers have a single, integrated sample measurement chamber that is either non-removable or requires complex disassembly. In practical use, sample powder and other impurities easily remain inside the chamber, making thorough cleaning difficult. This not only affects the accuracy of subsequent measurements but can also lead to cross-contamination between different samples. Furthermore, when the sample measurement chamber is damaged, its non-removable or difficult-to-disassemble nature results in high repair costs, sometimes even necessitating the replacement of the entire analyzer, leading to a waste of resources.
[0004] Therefore, it is necessary to provide a true density analyzer with a detachable sample measurement chamber to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to provide a true density analyzer with a detachable sample measurement chamber to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A true density analyzer employing a detachable sample measurement chamber, comprising:
[0008] The analyzer body has a measurement cavity at its top. A cavity body is movably inserted into the analyzer body through the measurement cavity. A sealing ring is fixedly installed on the upper outer wall of the cavity body. A symmetrically distributed positioning groove is provided on the outer surface of the sealing ring. A symmetrically distributed locking groove is provided on the inner wall of the positioning groove.
[0009] The top of the analyzer body is equipped with disassembly components on both sides of the measuring cavity, and the top of the cavity body is equipped with a sealing cap.
[0010] Preferably, symmetrically distributed buffer pads are fixedly installed on both sides of the bottom of the analyzer body.
[0011] By adopting the above technical solutions, vibration during analyzer placement can be reduced, protecting internal components; friction with the placement surface can be increased to prevent slippage; and direct contact between the bottom and the ground can be avoided, reducing wear and corrosion.
[0012] Preferably, the disassembly assembly includes two fixing blocks, which are symmetrically distributed and fixedly installed on the top of the analyzer body on both sides of the measuring cavity. The fixing blocks have fixing grooves, and rectangular columns are slidably inserted into both ends of the fixing grooves. Springs are fixedly installed inside the fixing grooves between the opposite ends of the two rectangular columns. A through groove is opened on the outer surface of the fixing blocks, and the through groove is connected to the inside of the fixing groove. An operating plate is fixedly installed on the outer wall of the opposite ends of the two rectangular columns, and the operating plate extends through the inside of the through groove to the outside of the fixing block.
[0013] By adopting the above technical solution, the rectangular column can be slidable via the control panel, making it easy to install and disassemble the cavity body and the analyzer body.
[0014] Preferably, rubber pads are adhered to the opposite surfaces of both operating plates.
[0015] By adopting the above technical solutions, the friction during operation is increased, making it easier to press; it can also buffer hand pressure, avoiding hand discomfort during operation; and it reduces wear on the control panel surface, extending its service life.
[0016] Preferably, the opposite ends of the two rectangular columns are inclined, and the rectangular columns are adapted to the locking groove, and the fixing block is adapted to the positioning groove.
[0017] By adopting the above technical solution, the rectangular column is automatically squeezed and retracted when the cavity body is inserted, thus achieving rapid installation.
[0018] Preferably, the cavity body is a hollow structure with an opening at one end.
[0019] By adopting the above technical solution, it is easy to put in and take out samples, which is beneficial for subsequent true density measurement of samples; such a structure also facilitates cleaning, maintenance and testing of the inside of the cavity, ensuring the accuracy of measurement results and the service life of the instrument.

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.
[0030] Example 1
[0031] Please see Figures 1-5 One embodiment provided by this utility model:
[0032] A true density analyzer employing a detachable sample measurement chamber, comprising:
[0033] The analyzer body 1 has a measuring cavity 4 on its top. The analyzer body 1 is movably connected to the cavity body 5 through the measuring cavity 4. A sealing ring 6 is fixedly installed on the upper outer wall of the cavity body 5. The outer surface of the sealing ring 6 is provided with symmetrically distributed positioning grooves 7. The inner wall of the positioning grooves 7 is provided with symmetrically distributed locking grooves 8. The top of the analyzer body 1 is provided with disassembly components 3 on both sides of the measuring cavity 4. The top of the cavity body 5 is provided with a sealing cover 2.
[0034] Specifically, the disassembly assembly 3 includes two fixing blocks 10, which are symmetrically distributed and fixedly installed on the top of the analyzer body 1 on both sides of the measuring cavity 4. The fixing blocks 10 have fixing grooves 15, and rectangular columns 14 are slidably inserted into both ends of the fixing grooves 15. Springs 16 are fixedly installed inside the fixing grooves 15 between the opposite ends of the two rectangular columns 14. A through groove 12 is opened on the outer surface of the fixing blocks 10, and the through groove 12 is connected to the inside of the fixing groove 15. An operating plate 11 is fixedly installed on the outer wall of the opposite ends of the two rectangular columns 14, and the operating plate 11 extends through the inside of the through groove 12 to the outside of the fixing block 10. Rubber pads 13 are glued to the opposite surfaces of the two operating plates 11. The opposite ends of the two rectangular columns 14 are inclined, and the rectangular columns 14 are adapted to the locking groove 8. The fixing blocks 10 are adapted to the positioning groove 7. The cavity body 5 is a hollow structure with one end open.
[0035] Furthermore, the disassembly of component 3 enables convenient assembly and disassembly of the cavity body 5 and the analyzer body 1, facilitating cleaning, maintenance, or replacement of the cavity body 5; the positioning groove 7 cooperates with the fixing block 10, and the locking groove 8 cooperates with the rectangular column 14 to ensure accurate and secure installation positioning; the sealing ring 6 and the sealing cover 2 ensure sealing performance and improve measurement accuracy.
[0036] Example 2
[0037] Reference Figure 3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and symmetrically distributed buffer pads 9 are fixedly installed on both sides of the bottom of the analyzer body 1.
[0038] Specifically, it can reduce vibration transmission during operation, avoiding impact on the placement surface; reduce interference from external vibrations on the analyzer, ensuring measurement stability; buffer collision impacts, protecting the analyzer body 1; and also reduce noise, creating a quiet working environment.
[0039] The working principle of this utility model is as follows: All parts not described herein are the same as or can be implemented using existing technology. When performing sample measurement, first open the sealing cover 2, place the sample to be measured inside the cavity body 5, and then close the sealing cover 2, ensuring a good seal. Next, connect the cavity body 5 to the analyzer body 1 using a quick connector. Start the analyzer and perform a true density measurement on the sample. When cleaning or maintenance of the cavity body 5 is required, ensure the equipment is not in operation. Directly operate the disassembly assembly 3, press the two operating plates 11 to move them relative to each other. This movement causes the rectangular column 14 to slide on the fixing groove 15. During the relative movement of the two rectangular columns 14, the spring 16 is compressed, and the rectangular column 14 disengages from the locking groove 8. At this time, the disassembly assembly 3 loses its positioning function on the sealing ring 6, and the cavity body 5 can be directly pulled out from the measuring cavity 4 through the sealing ring 6, thus completing the disassembly of the cavity body 5. During subsequent installation, the cavity body 5 is inserted into the measuring cavity 4, and the positioning groove 7 is aligned with the fixing block 10. When the fixing block 10 is inserted into the positioning groove 7, the inclined end of the rectangular column 14 abuts against the inner wall of the positioning groove 7, pushing the rectangular column 14 to move automatically into the fixing groove 15 and compress the spring 16. After the fixing block 10 is fully engaged, the rectangular column 14 automatically engages into the locking groove 8 under the elastic action of the spring 16, completing the installation of the cavity body 5 on the measuring cavity 4. At the same time, the assembly 3 is disassembled to achieve the positioning of the cavity body 5, and then the measurement work can continue.
[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
