Description

Technical Field

[0001] The utility model belongs to the field of textile testing instruments, in particular to a microscope loading device for textile testing. Background Art

[0002] Microscope is a very important instrument for experimenters to qualitatively analyze the fiber composition of textiles. Whether the microscope can clearly observe the different fiber morphologies of different fibers and the changes of different fibers in strong acids and alkalis has a great impact on the final judgment results of the experimenters. Experimenters need to use strong acid and alkali solutions in the qualitative process. Some strong acid solutions are volatile, and the volatile harmful gases will not only corrode the microscope, but also endanger the health of the experimenters.

DETAILED DESCRIPTION

[0025] The present invention is further described below through specific implementation methods.

[0026] Reference Figures 1 to 6 As shown, a microscope loading device for textile testing includes a loading platform 1, a placement rack 2, a mounting frame 3, a slide 4, and an exhaust filter mechanism 5.

[0027] The stage 1 is arranged below the microscope lens, and a third through hole 11 is formed through the stage 1 at a position relative to the microscope observation lens for the light from the bottom light source to pass through. A boss 12 is arranged on the side of the stage 1 away from the observation direction of the experimenter, and a limit groove 13 is formed by a horizontal inward depression at the bottom of the boss 12 near the third through hole 11.

[0028] The placement rack 2 is assembled on the stage 1, and is provided with a second through hole 21, a positioning hole 22 and an extension plate 23. The second through hole 21 is formed through the placement rack 2, and the light source light can pass upward from the third through hole 11 and the second through hole 21 in sequence; a plurality of positioning holes 22 are provided, which are evenly distributed on the placement rack 2; the extension plate 23 extends outward from one side of the placement rack 2 and can be extended into the limiting groove 13 to assemble the placement rack 2, and the position of the sample to be observed can be changed by moving the extension plate 23 in the limiting groove 13 so that it is located in the center of the field of view of the microscope.

[0029] The mounting frame 3 is arranged on the placement rack 2 and can be used to install the slide 4. The mounting frame 3 includes a base 31, a baffle 32, a limit block 33, a groove 34 and a positioning block 35. The base 31 is arranged in the placement rack 2. A first through hole 36 is formed on the base 31 and passes through from top to bottom and is opposite to the second through hole 21. The light source light can pass upward from the third through hole 11, the second through hole 21 and the first through hole 36 in sequence; the baffle 32 is L-shaped and is formed on the base 31, and is located on the side close to the exhaust filter mechanism 5, which is used to block the airflow to avoid affecting the observation effect; the limit block 33 is formed at the connection between the two ends of the L-shaped baffle 32 and the base 31, and the slide 4 is installed between the baffle 32 and the limit block 33. The limit block 33 cooperates with the baffle 32 to limit the lateral and longitudinal freedom of the glass slide 4 on the base 31, so that the experimenter can directly pick up the installation frame 3 for cleaning to prevent contact with strong acid and strong base reagents; the groove 34 is formed on the top surface of the base 31 around the edge of the glass slide 4 to accommodate the reagent overflowing from the glass slide 4, so that when the experimenter accidentally overflows the reagent from the glass slide 4 when dropping the strong acid and strong base reagent, the reagent can flow into the groove 34 without contaminating the main body of the stage 1; the positioning block 35 is arranged at the bottom of the base 31 in a one-to-one correspondence with the positioning hole 22 and its shape is adapted to the positioning hole 22, and is used to assemble the installation frame 3 in the placement rack 2.

[0030] The exhaust filter mechanism 5 is arranged on the stage 1 and faces the glass slide 4 to absorb and filter the gas volatilized from the glass slide 4. The exhaust filter mechanism 5 includes an air inlet 51, a filter element 52, an exhaust port 53 and an air duct 54. There are several air inlets 51, which are evenly distributed on the boss 12. The air inlet 51 faces one side of the glass slide 4 and is tilted upward at an angle of 45°. The tilted air inlet 51 is helpful for the discharge of harmful gases. Even if the volatile gas is not sucked into the air inlet 51, it can flow backward along the tilted air inlet 51 to avoid gas reflux and cause the experimenter to inhale harmful gases; the filter element 52 is connected to the air inlet 51 to filter the gas inhaled from the air inlet 51; one end of the exhaust port 53 is connected to the filter element 52 and receives the filtered gas, and the other end is connected to the external air pump to discharge the gas outward; the air duct 54 is sequentially connected between the air inlet 51, the filter element 52 and the exhaust port 53 to connect one end to the air inlet 51. The harmful gas volatilized from the slide 4 is collected through the air inlet 51 and filtered through the filter element 52 before being discharged from the exhaust port 53 to prevent the experimenter from inhaling it and protect the health of the experimenter. At the same time, the harmful gas is prevented from contacting other parts of the experimental device and corroding other parts of the experimental device, which can extend the service life of the experimental device. Specifically, the exhaust port 53 is connected to an external air suction device for air suction, which is an air pump commonly used in the prior art for gas flow. It is not the focus of this application, so it is not drawn and is not further described. Furthermore, the filter element 52 can be made of activated carbon.

[0031] When in use, the experimenter places the sample to be observed on the slide 4, covers it with a cover glass, places the slide 4 in the mounting frame 3, and installs the mounting frame 3 in the placement frame 2 by assembling the positioning block 35 at the bottom of the mounting frame 3 with the positioning hole 22. The extension plate 23 of the placement frame 2 extends into the limiting groove 13 and adjusts the position of the extension plate 23 in the limiting groove 13 so that the sample to be observed appears in the center of the microscope field of view. The exhaust port 53 is connected to the external suction device, and the exhaust filter mechanism 5 is started to work. The experimenter drips a strong acid or strong base reagent on the slide 4, and observes the fiber morphology of the sample and the changes of the sample in the reagent through the microscope eyepiece to determine the fiber composition of the observed sample. By means of the groove 34 provided in the mounting frame 3, when the experimenter accidentally causes the reagent to overflow the glass slide 4 when dropping the strong acid or strong base reagent, the reagent can flow into the groove 34 without contaminating the main body of the stage 1. At the same time, the experimenter can directly pick up the mounting frame 3 for cleaning to prevent contact with the strong acid or strong base reagent. In addition, when the exhaust filter mechanism 5 continuously inhales the harmful gas volatilized from the glass slide 4, the baffle 32 provided on the mounting frame 3 can be used to block the airflow to avoid affecting the observation effect, thereby having high practicality.

[0032] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
