Description

Technical Field

[0001] This utility model relates to the field of tuning fork density meter technology, specifically a direct-insertion tuning fork density meter. Background Technology

[0002] The tuning fork density sensor is designed based on the vibration principle of components. This vibrating element is similar to a two-toothed tuning fork. The fork body vibrates due to a piezoelectric crystal located at the root of the teeth. The frequency of the vibration is detected by another piezoelectric crystal. Through phase shifting and amplification circuits, the fork body is stabilized at its natural resonant frequency. When a medium flows through the fork body, the change in the mass of the medium causes a change in the resonant frequency.

[0003] When using a tuning fork density meter, it needs to be installed through a flange and a pipe. When using a flange for installation, the tuning fork density meter needs to be fixed by tightening bolts. Therefore, tools are needed to remove the bolts and nuts during installation and disassembly, which makes maintenance inconvenient when disassembling and cleaning the tuning fork density meter. Therefore, there is a need to propose a direct-insertion tuning fork density meter that is easy to install and disassemble. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a direct-insertion tuning fork density meter, including a locking structure 1, an mounting structure 2 installed on the top of the locking structure 1, and a fixing frame 11. A moving column 12 is movably connected to the inner wall of the top of the fixing frame 11, and a fixing box 13 is fixedly connected to the top of the fixing frame 11. A pull ring 14 is movably connected inside the fixing box 13, and a spring 15 is installed on the outside of one end of the pull ring 14. A telescopic block 16 is fixedly installed on one end of the pull ring 14. The fixing frame 11 is fixedly installed on the outer wall of the flange 4, thereby facilitating the fixing of the locking structure 1 to the flange 4. A silicone head is provided at the top of the moving column 12, and a wrench 24 is pressed between the moving column 12 and the telescopic block 16. The movable column 12 is movably disposed inside the fixed frame 11, thereby facilitating the pushing of the movable column 12 to the squeeze wrench 24, and thus facilitating the squeezing and pushing of the wrench 24 out from the groove at the top of the fixed frame 11. The telescopic block 16 is movably disposed inside the fixed box 13. One end of the telescopic block 16 has an arc-shaped structure. The arc-shaped structure facilitates the pushing of the telescopic block 16 into the fixed box 13 when the wrench 24 is pressed down, thereby facilitating the use of the telescopic block 16 to limit the wrench 24. The telescopic block 16 is elastically installed to the fixed box 13 by the spring 15. The fixed box 13 is fixedly connected to the top of the fixed frame 11. The telescopic blocks 16 are symmetrically disposed on both sides of the wrench 24. The mounting structure 2 includes a nut 21, and a connecting plate 22 is welded to the outer wall of the nut 21.

[0023] A rotating column 23 is fixedly connected to one side of the connecting plate 22, and a wrench 24 is rotatably mounted on the outer wall of the rotating column 23. The connecting plates 22 are symmetrically installed on one side of the nut 21, and the rotating column 23 is fixedly connected between the connecting plates 22. One side of the wrench 24 has a cam-shaped structure. The cam-shaped wrench 24 facilitates pressing the mounting seat 6 after rotation, thereby facilitating the reinforcement installation of the mounting seat 6 and the flange 4. The wrench 24 is pressed and positioned on the top of the mounting seat 6. A stop bar 25 is fixedly installed between the connecting plates 22, and one side of the wrench 24 is pressed and positioned on the top of the stop bar 25 after rotation. A stop bar 25 is fixedly connected to one side of the connecting plate 22. A mounting bolt 3 is threadedly connected to the inner wall of the nut 21, and a flange 4 is fixedly connected to the bottom end of the mounting bolt 3. A flow pipe 5 is fixedly installed at the bottom of the flange 4, and a mounting seat 6 is installed at the top of the flange 4. The top outer wall of the mounting bolt 3 is provided with external threads, and the mounting bolt 3 is installed at an equal angle at the top of the flange 4. The mounting bolt 3 is inserted into the mounting seat 6, and the mounting seat 6 has a mounting hole corresponding to the mounting bolt 3. The tuning fork density meter body 7 is fixedly connected to the inner wall of the mounting seat 6. A second sealing plate 9 is fixedly connected to the bottom of the mounting seat 6, and a first sealing plate 8 is fixedly connected to the top of the flange 4. The top of the first sealing plate 8 is provided with an annular protrusion, which increases the degree of deformation when the first sealing plate 8 and the second sealing plate 9 are squeezed against each other, thereby improving the sealing performance between the flange 4 and the mounting seat 6. The first sealing plate 8 and the second sealing plate 9 are squeezed and adhered between the mounting seat 6 and the flange 4.

[0024] Working principle: When using this direct-insertion tuning fork density meter, insert the tuning fork density meter body 7 into the flow tube 5, then insert the mounting bolt 3 into the mounting base 6, then put the nut 21 on the outside of the mounting bolt 3 and squeeze the vertical wrench 24 to rotate the nut 21, thereby tightening the nut 21 on the outside of the mounting bolt 3. While tightening, move the wrench 24 towards the fixing box 13, then press the wrench 24 down, thereby pressing the protruding part of the wrench 24 against the mounting base 6, thereby pressing the mounting base 6 against the flange 4, causing the sealing plate 8 and sealing plate 9 between the flange 4 and the mounting base 6 to deform and seal. At the same time, the wrench 24 presses the telescopic block 16, causing the telescopic block 16 to retract into the fixing box 13. When the wrench 24 presses against the stop bar... After the top of the 25, the telescopic block 16 is popped back to its original position by the elasticity of the spring 15, thereby fixing the wrench 24 between the stop bar 25 and the telescopic block 16, so as to facilitate the limiting and fixing of the nut 21 to the outside of the mounting bolt 3. When disassembling the tuning fork density meter body 7, insert two fingers into the two pull rings 14 and push them outward, thereby moving the telescopic block 16 into the fixing box 13, and then removing the limiting of the wrench 24. Next, press the moving column 12 upward, thereby pushing the wrench 24 upward out of the top of the fixing bracket 11. Then pinch the wrench 24 and rotate the nut 21 in the opposite direction, thereby removing the wrench 24 from the outside of the mounting bolt 3, thereby facilitating the removal of the mounting seat 6 from the top of the flange 4, and then taking out the tuning fork density meter body 7 for cleaning.
