[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] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0023] Combination Figure 1 as well as Figure 2 A sealing device for a moisture analyzer for velixigua raw materials includes a base 1, a measuring chamber 2 fixedly connected to the upper surface of the base 1, a cover 21 hinged to the upper surface of the measuring chamber 2, a U-shaped groove 23 formed in the inner wall of the measuring chamber 2, an insert plate 211 fixedly connected to the bottom surface of the cover 21, the insert plate 211 being correspondingly arranged with the U-shaped groove 23, a sealing component B4 for sealing the U-shaped groove 23 being provided inside the measuring chamber 2, an installation groove being provided on one side of the measuring chamber 2, a handle 26 being provided inside the installation groove, and a sealing component A3 for sealing the handle 26 being provided on one side of the measuring chamber 2.
[0024] The present invention will be further described below with reference to the embodiments.
[0025] Combination Figures 1-6 The sealing component B4 includes an air storage tube 43 disposed inside the measuring chamber 2. An inclined top pressure rod 41 is slidably connected to the upper end of the air storage tube 43, and a sealing plate 42 is fixedly connected to the bottom end of the inclined top pressure rod 41. The sealing plate 42 is in contact with the inner wall of the air storage tube 43. A gas delivery hose 44 is fixedly connected to the bottom end of the air storage tube 43. An air bladder 45 is disposed on the inner wall of the U-shaped groove 23. One end of the gas delivery hose 44 is connected to the air bladder 45. A rubber sealing gasket A46 is fixedly connected to one side of the air bladder 45. The rubber sealing gasket A46 is in contact with the outer side of the insert plate 211. When the moisture content is measured, the chamber cover 21 is closed. The chamber cover 21 squeezes the inclined top pressure rod 41, causing the sealing plate 42 to press down. The sealing plate 42 squeezes the air inside the air storage tube 43, thereby causing the air bladder 45 to inflate. This allows the rubber sealing gasket A46 to fit against the inner wall of the insert plate 211, thereby improving the sealing effect at the sealing contact position when closed.
[0026] The measuring chamber 2 has a sliding groove 25 on one side. The sealing component A3 includes a spring A31 fixedly connected to the inner wall of the sliding groove 25. A push plate 32 is fixedly connected to one end of the spring A31. A stop block 33 is fixedly connected to one side of the push plate 32. The stop block 33 is slidably connected inside the sliding groove 25 and is correspondingly set to the mounting groove. A receiving groove 34 is opened on the bottom surface of the stop block 33. A spring B341 is fixedly connected to the inner wall of the receiving groove 34. A mounting plate 35 is fixedly connected to the bottom surface of the spring B341. The mounting plate 35 fits against the inner wall of the mounting groove. A rubber seal is fixedly connected to the bottom surface of the mounting plate 35. The sealing gasket B351 is attached to the upper surface of the handle 26. Before the object to be measured is installed, the push plate 32 is manually pressed, and the stop block 33 is retracted into the sliding groove 25 while compressing the spring A31. After the object to be measured is placed, the push plate 32 is released and pops out under the restoring force of the spring A31. During the movement of the stop block 33, the mounting plate 35 corresponds to the mounting groove and pops out under the action of the spring B341. The elastic force of the spring B341, together with the rubber sealing gasket B351, presses the surface of the handle 26 to achieve a sealing effect.
[0027] The mounting plate 35 has a magnetic plate A352 inside, and the handle 26 has a magnetic plate B261 inside. The magnetic plates A352 and B261 attract each other. When the mounting plate 35 presses the handle 26, the magnetic plates A352 and B261 attract each other, which further enhances the connection effect during sealing.
[0028] The upper surface of the stop block 33 is provided with a top groove 331, and the inner wall of the top groove 331 is provided with a rubber sealing gasket C. The top groove 331 is correspondingly provided with the insert plate 211. When the insert plate 211 is pressed down, the insert plate 211 fits with the top groove 331 to ensure the sealing effect.
[0029] The measuring chamber 2 is equipped with a storage frame 24 and a halogen lamp. The storage frame 24 is equipped with a storage tray 27. One end of the handle 26 passes through one side of the storage frame 24 and is fixedly connected to the storage tray 27. During the measurement, the object to be measured is placed inside the storage frame 24 by using the handle 26 in conjunction with the storage tray 27. After the sealing work is completed, the heating work is carried out by the halogen lamp.
[0030] The measuring chamber 2 is equipped with a collecting component 5 for collecting water vapor. The collecting component 5 includes a connecting plate 52 fixedly connected to the upper surface of the measuring chamber 2, a collecting tray 51 fixedly connected to the bottom surface of the connecting plate 52, the collecting tray 51 being correspondingly arranged with the storage frame 24, a valve 53 being installed inside the connecting plate 52, a collecting chamber being installed inside the measuring chamber 2, a fan being installed inside the collecting chamber, the connecting plate 52 being connected to the collecting chamber, and a side cover 22 being movably connected to the outside of the measuring chamber 2, the side cover 22 being correspondingly arranged with the collecting chamber. During the heating process, the fan inside the collecting chamber is turned on, and the fan, together with the collecting tray 51 and the connecting plate 52, collects the water vapor generated inside the storage frame 24. When the weight does not change, the fan and the valve 53 are turned off, and the measurement is completed.
[0031] Specifically, by setting sealing components A3 and B4, before the object to be measured is installed, the push plate 32 is manually pressed, compressing the spring A31 while the stop block 33 is housed inside the sliding groove 25. After the object to be measured is placed, the push plate 32 is released, and the push plate 32 pops out under the restoring force of the spring A31. The mounting plate 35 corresponds to the mounting groove and pops out under the action of the spring B341. The elastic force of the spring B341, together with the rubber sealing gasket B351, presses the surface of the handle 26 to achieve a sealing effect. Then, the box cover 21 squeezes the inclined top pressure rod 41 to drive the sealing plate 42 down. The sealing plate 42 squeezes the air inside the air storage tube 43, thereby causing the airbag 45 to inflate. This allows the rubber sealing gasket A46 to adhere to the inner wall of the insert plate 211, improving the sealing effect and achieving the purpose of improving the sealing effect of the measuring instrument and preventing the entry of outside air.
