Description

Technical Field

[0001] The utility model relates to the field of cedar oil detection equipment, in particular to a glass slide which can prevent oil from overflowing. Background Art

[0002] A slide is a transparent sheet used to place experimental materials during experiments. It is usually rectangular or circular in shape and is used together with a cover glass. When observing objects under a microscope, the object needs to be placed on the slide and then covered with a cover glass so that it can be placed under the microscope lens for observation.

[0003] Existing glass slides have some obvious defects when testing cedar oil. Specifically, after cedar oil is dripped on the glass slide, if the glass slide is moved, the cedar oil tends to overflow as the knob moves, contaminating the stage and condenser, which not only increases the difficulty of cleaning the microscope, but may also damage the microscope components due to long-term accumulation of stains and oil stains, thereby shortening its service life. In addition, when using existing cover glass, the operation process is also relatively cumbersome. It is usually necessary to hold the glass slide with one hand to fix its position, and use the other hand to carefully press one side of the cover glass against the hand to form an angle of about thirty degrees, and then slowly cover it down to ensure that the sample between the cover glass and the slide is evenly distributed. However, in this process, the hand may accidentally touch the surface of the cover glass, thereby introducing contaminants and affecting the accuracy of the test results. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an oil spill-proof slide to solve the technical problems of existing slides in the process of cedar oil detection, such as easy oil spillage, cumbersome operation and possible introduction of pollutants, which affect the accuracy of the detection results and the service life of the microscope.

[0005] To achieve the above object, the utility model provides the following technical solutions: an oil-overflow-proof glass slide, comprising a glass slide and a cover glass, the glass slide comprising a first sheet body, an anti-overflow groove is provided in the middle of the top of the first sheet body, and a first oil-proof film is provided on the outer side of the top of the first sheet body;

[0006] The cover glass comprises a second sheet body, a pressure-leveling block is arranged in the middle of the bottom of the second sheet body, the pressure-leveling block is matched with the anti-overflow groove, and a second oil-proof film is arranged on the outer side of the bottom of the second sheet body;

[0007] An auxiliary mechanism is slidably engaged on the first sheet body, and the auxiliary mechanism includes a ring, which is sleeved with the first sheet body. A contact block is arranged on one side of the ring, and the contact block is used to assist the cover glass to be quickly attached to the slide.

[0008] By adopting the above technical solution, through the specific structure of the slide and cover glass, and the setting of the auxiliary mechanism, the problems of oil overflow and sample contamination are effectively solved.

[0009] Furthermore, the first oil-proof film and the second oil-proof film are made of transparent fluororesin.

[0010] By adopting the above technical solution, the first oil-proof film and the second oil-proof film are made of transparent fluororesin, which has good oil-proof performance and can effectively reduce the direct contact between cedar oil and the slide glass and cover glass.

[0011] Furthermore, a particle layer is provided on one side of the first oil-proof film, and the particle layer is used to increase the friction of the glass slide to prevent the glass slide from slipping out of the hand.

[0012] By adopting the above technical solution, a particle layer is provided on one side of the first oil-proof film, and its fine particle structure can effectively increase the friction force on the surface of the slide, making it more stable when the user holds or operates the slide.

[0013] Furthermore, a curved chamfer is provided on one side of the second sheet body, and the curved chamfer facilitates forming a thirty-degree bevel angle when the cover glass abuts against the abutment block.

[0014] By adopting the above technical solution, an arc chamfer is provided on one side of the second sheet body. This setting enables a bevel angle of about thirty degrees to be naturally formed when the cover glass contacts the abutment block of the auxiliary mechanism.

[0015] Furthermore, the anti-overflow groove and the first oil-proof film and the second oil-proof film are all used to prevent the observation oil from overflowing.

[0016] By adopting the above technical solution, the combination of the anti-overflow groove, the first oil-proof film and the second oil-proof film constitutes an effective oil-proof system. The anti-overflow groove can collect and contain the overflowed cedar oil to prevent it from contaminating other parts of the microscope.

[0017] Furthermore, the auxiliary mechanism is made of silicone.

[0018] By adopting the above technical solution, the auxiliary mechanism is made of silicone material, which has good elasticity and durability, so that the auxiliary mechanism can better fit on the slide and maintain stable performance during long-term use.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] 1. The utility model is provided with an anti-overflow groove, a first anti-oil film, a second anti-oil film, and an auxiliary mechanism, wherein the anti-overflow groove is arranged in the middle position, which can effectively prevent the cedar oil from overflowing when the slide is moved, thereby avoiding contamination of the stage and the condenser, and solving the problem of increased difficulty in cleaning the microscope and damage to components caused by easy overflow of cedar oil. At the same time, the first anti-oil film and the second anti-oil film made of transparent fluororesin have good oil-proof performance, which can reduce the direct contact between cedar oil and the slide and cover glass, further prevent oil stain pollution, and reduce the accumulation of stains and oil stains during long-term use, thereby extending the service life of the microscope. The setting of the pressure block and the anti-overflow groove is matched , which can ensure that the sample between the cover glass and the slide is evenly distributed when it is placed, simplifies the use process of the cover glass, and no longer needs to carefully form an angle and slowly cover it, thereby improving the convenience of operation. In addition, the auxiliary mechanism includes a collar and an abutment block, which can conveniently assist the cover glass to be quickly and accurately attached to the slide, without directly pressing the slide with the hand, thereby avoiding the problem that the hand may accidentally touch the surface of the cover glass and introduce contaminants. In summary, the setting of these structures not only effectively solves the problems of easy oil overflow, cumbersome operation and possible introduction of contaminants during the detection of cedar oil, but also improves the service life of the microscope and the accuracy of the detection results;

[0021] 2. The utility model sets a particle layer and an arc chamfer, wherein the particle layer is set on one side of the first oil-proof film, and its fine particle structure can effectively increase the friction of the surface of the slide, making the user more stable when holding or operating the slide, and avoiding the slide from falling out of the hand due to slippery hands or careless operation. At the same time, the arc chamfer set on one side of the second sheet body allows the cover glass to naturally form an angle of about 30 degrees when it contacts the abutment block of the auxiliary mechanism, which not only simplifies the placement process of the cover glass, but also ensures that the sample between the cover glass and the slide can be evenly distributed, improving the convenience of operation and the accuracy of the test results.
