Description

Technical Field

[0001] The present application relates to the technical field of engineering material inspection, and in particular to a positioning tool for a glass slide sample. Background Art

[0002] When testing fine building materials such as sand and gravel, the material is mixed with glue and placed on a glass slide, which is then covered with a cover glass to form a sample. The sample is then placed under a microscope to observe information such as the material's particle distribution, shape, size, and surface morphology in order to judge the performance of the building material.

[0003] In view of the above-mentioned related technologies, when preparing the sample, gaps are easily generated when the glue and the material are mixed. When the cover glass is put on, these gaps will form bubbles. The bubbles in the sample will interfere with the observation of the sample and affect the inspection personnel's judgment on the performance of the building material. Utility Model Content

[0004] In order to improve the situation where bubbles exist in a sample, the present application provides a positioning tool for a glass slide sample.

[0005] The present application provides a positioning tool for a glass slide specimen, which adopts the following technical solution:

[0006] A positioning tool for a slide sample comprises: a base, a bracket and a pressing assembly; the base is connected to the bracket, the pressing assembly comprises a pressing piece and an elastic piece, the pressing piece is movably connected to the bracket, and the elastic piece is installed on the bracket to give the pressing piece a force to move toward the base so that the pressing piece can press the sample against the base.

[0007] By adopting the above technical solution, the sample is pressed against the base by the pressing member, and the elastic member gives power to the pressing member and acts on the sample at the same time, so that the sample is subjected to the squeezing force of the pressing member, so that the bubbles in the sample are gradually squeezed out, thereby eliminating the bubbles in the sample and improving the observation quality.

[0008] Optionally, the extrusion assembly further includes a pressing head, the pressing head is connected to one end of the pressing member close to the base, and an outer edge of the pressing head exceeds an outer edge of the pressing member.

[0009] By adopting the above technical solution, the pressure head increases the contact area between the extrusion component and the sample, so as to increase the range of squeezing bubbles on the sample.

[0010] Optionally, the thickness of the pressure head increases gradually along a direction approaching the center of the pressing piece.

[0011] By adopting the above technical solution, the gradual increase in the thickness of the pressure head makes the pressure head have a stronger anti-deformation ability, so that the pressure head is not easy to deform under the pressure of the pressing piece.

[0012] Optionally, the pressing head is movably connected to the pressing member, and a moving direction of the pressing head is parallel to a direction in which the pressing member presses the sample.

[0013] By adopting the above technical solution, in the process of the pressing member pressing against the sample, the pressure head first contacts the sample, and then the pressing member is pressed against the pressure head by the power of the elastic member. The pressing member squeezes the sample through the pressure head, and relative movement occurs between the pressing member and the pressure head to reduce the impact force of the pressing member on the sample, making the sample less likely to be damaged.

[0014] Optionally, the pressing member has a convex edge, and the elastic member is connected between the convex edge and the bracket.

[0015] By adopting the above technical solution, the elastic member is connected between the convex edge and the bracket, so that when the pressing member is moved relative to the bracket, the elastic member can be driven to deform.

[0016] Optionally, the extrusion assembly further comprises a handle connected to an end of the pressing member away from the base.

[0017] Optionally, the extrusion components are arranged in multiple groups on the bracket.

[0018] By adopting the above technical solution, multiple groups of extrusion components can press different samples individually, so that multiple samples can be defoamed at the same time, thereby improving the sample preparation efficiency.

[0019] Optionally, the positioning tool further includes a heating platform, on which the base is placed, and the base is made of a heat-conducting material.

[0020] By adopting the above technical solution, the base is placed on a heating table and heated by the heating table, and the base conducts heat to the sample to accelerate the drying speed of the glue in the sample and improve the sample preparation efficiency.

[0021] In summary, the present application includes at least one of the following beneficial effects:

[0022] 1. The sample is pressed against the base by the pressure head, and the elastic member drives the pressure head to press the sample, so that the cover glass in the sample is pressed against the slide glass, and the glue between the cover glass and the slide glass is squeezed and gradually eliminated, thereby improving the situation of bubbles in the sample and improving the subsequent observation quality of the sample;

[0023] 2. When the pressing member presses against the sample, the friction force generated by the relative movement between the pressure head and the pressing member reduces the impact force of the pressing member on the sample;

[0024] 3. The heating table heats the base. The base made of heat-conductive material can transfer heat to the sample to speed up the drying of the glue in the sample. The glue is dried while defoaming, which improves the efficiency of sample preparation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] Embodiment 1:

[0032] The present application embodiment discloses a positioning tool for a glass slide sample. Figure 1 The positioning tool for the slide sample includes a base 1, a bracket 2 and a pressing assembly 3. The bracket 2 is installed on the base 1, and the pressing assembly 3 is movable on the bracket 2, and is used to abut the sample against the base 1 to press the sample.

[0033] The base 1 is in the shape of a square plate. The bracket 2 includes a support rod 21 and a support plate 22. The support rod 21 has a plurality of support rods and is vertically fixed around the base 1, and the support rod 21 is perpendicular to the surface of the base 1. The support plate 22 is in the shape of a square plate, and the support plate 22 is fixed to one end of the support rod 21 away from the base 1. The support plate 22 is opposite to the base 1 and the surfaces are parallel to each other.

[0034] Reference Figure 1 and Figure 2 A plurality of extrusion assemblies 3 are installed in an array on the support plate 22 , and each extrusion assembly 3 includes a pressing member 31 , an elastic member 32 , a pressing head 33 and a handle 34 .

[0035] The pressing member 31 is in the shape of a long rod, and includes a sliding section 311, an extension section 312, and a flange 313. The sliding section 311 and the extension section 312 are both in the shape of round rods and are coaxially fixedly connected. The outer diameter of the sliding section 311 is larger than the outer diameter of the extension section 312. The pressure head 33 is connected to the end of the sliding section 311 away from the extension section 312, and the handle 34 is connected to the end of the extension section 312 away from the sliding section 311. The flange 313 is in the shape of a ring and is sleeved on the end of the sliding section 311 close to the extension section 312. The flange 313 is coaxial with the sliding section 311, and the outer diameter of the flange 313 is larger than the outer diameter of the sliding section 311.

[0036] The sliding section 311 is slidably disposed on the support plate 22 in a direction perpendicular to the surface of the support plate 22 to drive the extension section 312 , the flange 313 and the pressure head 33 to move between the support plate 22 and the base 1 , and the axis of the sliding section 311 is perpendicular to the surface of the support plate 22 .

[0037] The elastic member 32 is connected between the support plate 22 and the convex edge 313, and provides the convex edge 313 with power to move toward the direction close to the base 1. In this embodiment, the elastic member 32 is preferably a spring, the inner diameter of the spring is close to the outer diameter of the sliding section 311, the spring is sleeved on the outer wall of the sliding section 311 and is coaxial with the sliding section 311, and the opposite ends of the spring are respectively connected to the lower surface of the support plate 22 and the upper surface of the convex edge 313. In other embodiments, the elastic member 32 can also be a spring sheet, elastic rubber, etc.

[0038] When in use, first pull up the pressure head 33 through the handle 34, the spring is squeezed by the convex edge 313, then put the sample with the glue not dried on it on the base 1 and under the pressure head 33, and then release the tension on the spring, so that the spring drives the convex edge 313 to reset downward, so as to drive the pressure head 33 to abut and squeeze the sample downward, so that the slide glass and cover glass of the sample are squeezed together to squeeze the glue and material mixture, thereby eliminating the bubbles in the glue.

[0039] Reference Figure 2 and Figure 3 More specifically, the pressure head 33 is circular and the side of the pressure head 33 facing the base 1 is a horizontal plane parallel to the base 1. The extension section 312 of the pressure head 33 is coaxially arranged, the outer diameter of the pressure head 33 is larger than the outer diameter of the extension section 312, and the pressure head 33 moves axially along the extension section 312 at one end of the extension section 312 close to the base 1.

[0040] In this embodiment, a movable column 5 and a movable ball 6 are fixed to the top of the pressure head 33 from bottom to top in sequence. The movable column 5 and the movable ball 6 are coaxial with the pressure head 33, and the outer diameter of the movable column 5 is smaller than the diameter of the movable ball 6, and the diameter of the movable ball 6 is smaller than the outer diameter of the extension section 312. A movable groove 7 is provided upwardly at the bottom of the extension section 312 for the movable ball 6 to slide axially along the extension section 312, and the bottom end of the extension section 312 has a limiting portion 8 protruding inwardly to abut against the outer peripheral wall of the movable column 5, so as to limit the movable ball 6 in the extension section 312, and to ensure that the movable column 5 and the pressure head 33 always maintain a coaxial position with the extension section 312 when the movable ball 6 moves.

[0041] In the process of the spring returning downward to drive the pressure head 33 downward to contact the sample, the pressure head 33 will move downward relative to the extension section 312 under the action of its own gravity until the movable ball 6 abuts against the limiter 8; then the pressure head 33 abuts against the sample cover glass, and the extension section 312 moves downward relative to the pressure head 33 to abut against the top of the pressure head 33. During this process, the friction between the movable ball 6 and the inner wall of the extension section 312 slows down the descent of the extension section 312, thereby reducing the impact force on the sample when the pressure head 33 abuts against the sample, making the sample less likely to be damaged. In other embodiments, the pressure head 33 can also be directly fixed to the bottom end of the sliding section 311.

[0042] Reference Figure 2 and Figure 3 Furthermore, the thickness of the pressure head 33 gradually decreases from the center of the pressure head 33 to the outer circumference, so that the pressure head 33 is in a truncated cone shape to improve the anti-deformation ability of the middle part of the pressure head 33. Therefore, when the extension part frequently contacts the pressure head 33, the pressure head 33 is not easy to deform, so as to extend the service life of the pressure head 33.

[0043] Reference Figure 1 and Figure 2 In addition, when the pressing head 33 abuts against the base 1 and the extending section 312 abuts against the pressing head 33 , the handle 34 abuts against the upper surface of the support plate 22 to save the material of the sliding section 311 .

[0044] The implementation principle of the positioning tool for a glass slide sample in the embodiment of the present application is as follows: a sample with wet glue is placed on the base 1, and the spring drives the pressure head 33 to press the sample tightly to squeeze and eliminate bubbles in the sample glue.

[0045] Embodiment 2:

[0046] The embodiment of the present application discloses a positioning tool for a glass slide sample. The difference between the embodiment of the present application and the first embodiment is that, with reference to Figure 4 The slide sample positioning tool also includes a heating platform 4, the surface of which is made of a heat-conducting metal, preferably iron. The heating platform 4 has a heating element (not shown in the figure) inside, which transfers heat to the surface of the heating platform 4.

[0047] The base 1 is made of a heat-conducting material, preferably iron in this embodiment. The base 1 is placed on the heating platform 4, and the heating platform 4 transfers heat to the sample placed on the base 1 through the base 1, so that the glue in the sample is dried while being defoamed, which reduces the glue drying time and improves the sample preparation efficiency.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
