Description

Technical Field

[0001] This invention relates to the field of laboratory cleaning equipment accessories technology. Specifically, it relates to a device for installing glass slides in laboratory cleaning equipment. It is suitable for the dedicated installation and fixing of glass slides and the protection of the test environment in various cleaning experiments such as the removal of heavy oil stains from new products in the laboratory. It belongs to the technical category of laboratory test auxiliary devices. Background Technology

[0002] In laboratory research and testing, conducting cleaning performance tests on new products, such as those for removing heavy oil stains, is a core experimental step. These tests require specialized cleaning equipment with glass slides mounted as test carriers to accurately detect and collect data on the cleaning product's performance. However, currently, laboratories face several technical challenges in conducting these tests: First, there is a lack of specialized slide installation devices adapted to cleaning equipment. Manual placement of slides presents problems such as installation difficulties, low positioning accuracy, easy scratching and damage, and loosening and displacement during the test, which directly affect the accuracy of the test results. Secondly, the glass slides and mounting devices are exposed in the equipment, making them susceptible to splashing test liquids and interference from the external environment. At the same time, the lack of a dedicated containment and protection structure leads to a high risk of test contamination, easy collision damage to the equipment, and a shortened service life. Third, the high cost of customized commercial components significantly increases research and development expenditures.

[0003] Therefore, developing a special mounting device for laboratory cleaning equipment slides that is simple in structure, stable in installation, low in cost, and has basic protective functions is the key to solving the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the technical defects in the installation of glass slides in existing laboratory cleaning tests, and to provide a device for installing glass slides in laboratory cleaning equipment.

[0005] Firstly, it solves the technical problems of difficult glass slide installation, easy scratching, and easy loosening and displacement, thereby improving the convenience of experimental operation and the stability of equipment operation; Secondly, the cylindrical protective enclosure provides physical protection and isolation from the test environment for the glass slides and mounting components, reducing the impact of liquid splashes and external collisions. Third, the simple hierarchical structure design replaces high-cost commercial components, saving research costs and improving the effective utilization of funds; Fourth, it enables precise positioning and multiple limiting fixation of the glass slide, ensuring the accuracy and repeatability of cleaning test results.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An apparatus for mounting glass slides on laboratory cleaning equipment includes a glass slide mounting assembly and a cylindrical protective housing (5). The slide mounting assembly consists of an upper structure (1), a middle structure (2) and a lower structure (3) that are stacked and connected from top to bottom. The three structures work together to form a mounting cavity (4) that is adapted to the mounting of the slide. The upper structure (1) has an edge spacing of 1mm and an overall horizontal dimension of 40mm; the middle structure (2) has a longitudinal dimension of 26mm and a horizontal dimension on one side of 29mm; the lower structure (3) has an overall horizontal dimension of 40mm and a longitudinal dimension on both sides of 19mm, and the lower end face is a fitted structure adapted to the testing station of the laboratory cleaning equipment. The cylindrical protective housing (5) is a hollow structure with an open top. The inner cavity size is adapted to the overall shape of the slide mounting assembly, and the slide mounting assembly can be completely accommodated in the inner cavity.

[0007] Furthermore, four sets of through-holes with matching number, diameter, and position are opened at the corresponding corner positions of the upper structure (1), middle structure (2), and lower structure (3). The mounting holes avoid the area of ​​the mounting cavity (4) and are evenly distributed at the four corners. Adjacent structures are connected by corresponding mounting holes through stainless steel threaded rods (6) and tightened with nuts (7) to achieve detachable fixed connection.

[0008] Furthermore, the diameter of the threaded rod (6) is precisely matched with the diameter of the mounting hole, and the length is matched with the total thickness of the superimposed upper structure (1), middle structure (2), and lower structure (3). The nut (7) is perfectly matched with the thread specification of the threaded rod (6).

[0009] Furthermore, the upper structure (1), middle structure (2) and lower structure (3) are integral injection-molded structures of rigid plastic, with no splicing gaps.

[0010] Furthermore, the inner dimensions of the mounting cavity (4) are precisely matched with the outer dimensions of a conventional laboratory slide, thereby achieving embedded and limited installation of the slide; the lower surface of the upper structure (1) is fitted with the top end face of the slide to form a top pressing limit; the middle structure (2) provides a wrapping support for the middle circumferential part of the slide; and the upper end face of the lower structure (3) is a planar support surface that provides stable support for the bottom of the slide.

[0011] Furthermore, the cylindrical protective enclosure (5) is made of 304 stainless steel, which has the characteristics of being resistant to oil and corrosion.

[0012] The present invention provides a device for mounting glass slides in laboratory cleaning equipment, which, compared with the prior art, has the following significant advantages: 1. Easy and secure installation: The embedded mounting cavity design precisely matches the glass slide, and with the all-round limiting of upper pressing, middle support, and lower support, the installation of the glass slide is simple and easy, without the need for complicated manual positioning, which greatly improves the operational efficiency of laboratory cleaning tests; the four sets of mounting holes distributed at the four corners, combined with the connection method of stainless steel threaded rods and nuts, make the structure tightly overlap, and the integrated molding design further enhances the structural strength, fundamentally avoiding the problems of loosening, displacement and scratching of the glass slide during the test, and ensuring the stable operation of the test.

[0013] 2. Excellent protection and strong adaptability: The matching 304 stainless steel cylindrical protective enclosure can completely contain the installation components and glass slides, effectively reducing the impact of liquid splashes and external collisions on the glass slides and installation components during the test, and reducing the probability of glass slide breakage and device damage; the enclosure has an open top and no top cover design to adapt to the test operation requirements, and the stainless steel material is oil-resistant and corrosion-resistant, and can be adapted to various clean test scenarios.

[0014] 3. Simple structure and low cost: The device adopts a hierarchical split structure or an integrated molding structure design, which is simple in structure, the raw materials are readily available, and the processing technology is simple. It can directly replace the high-cost customized commercial glass slide mounting accessories, which can significantly reduce laboratory expenses, save research costs, and significantly improve the effective utilization rate of research funds, meeting the needs of low-cost laboratory experiments.

[0015] 4. Two structural options to meet diverse needs: The device offers two structural design options: a detachable design and an integrated design. The detachable design allows for flexible assembly and disassembly of each structure through threaded rods and nuts, facilitating cleaning, maintenance, and individual repair and replacement of parts, thus reducing later operating costs. The integrated design offers high structural strength and good vibration resistance, making it suitable for high-intensity, high-frequency, and high-vibration cleaning test scenarios in laboratories. Both options can meet the test equipment and test requirements of different laboratories, with a wide range of applications and strong practicality.

[0016] 5. Ensuring accurate and reliable test results: The device achieves stable placement of the glass slide during the test through all-round limiting and fixing. Combined with the environmental isolation effect of the protective enclosure, it effectively avoids the influence of glass slide loosening, displacement and external interference on the test, ensuring the accuracy, reliability and repeatability of cleaning test results, and providing a stable test carrier guarantee for the research and development, testing and performance verification of laboratory cleaning products.

Figure 2This is a schematic diagram (II) of the overall structure of a device for mounting glass slides in laboratory cleaning equipment according to the present invention. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] This invention proposes a device for mounting glass slides in laboratory cleaning equipment. The device consists of two parts: a glass slide mounting assembly and a cylindrical protective housing. The two parts work together to complete the mounting, fixing, and experimental protection of the glass slides. (a) Slide mounting assembly The design adopts a split-type hierarchical structure, which consists of an upper structure (1), a middle structure (2) and a lower structure (3) that are stacked and connected from top to bottom. The three structures work together to form a closed mounting cavity (4) that is suitable for the installation of conventional laboratory slides. The inner size of the mounting cavity (4) is precisely matched with the outer size of conventional laboratory slides, so as to realize the embedded and limited installation of the slides. It forms a comprehensive positioning constraint on the slides from the longitudinal and transverse directions, so as to avoid the slides from loosening, displacement and scratching during the test.

[0020] The upper structure (1) is the top limiting end of the device. Its edge spacing is 1mm and the overall horizontal dimension is 40mm. The lower surface is tightly attached to the top end face of the glass slide to form a top pressing limit, which effectively prevents the glass slide from moving longitudinally during the test. Four sets of through-type mounting holes are opened at the corresponding corner positions, which are evenly distributed at the four corners and are only used for connecting and fixing between the various structures. They avoid the area of ​​the mounting cavity (4) and do not affect the installation and limiting of the glass slide.

[0021] The middle structure (2) is the main body connection and middle support end of the device. It is the core part connecting the upper structure (1) and the lower structure (3). The longitudinal dimension is 26mm and the transverse single-sided dimension is 29mm. It encloses and forms an annular support and limiting space that fits the middle of the glass slide. It forms a wrapping support for the middle circumference of the glass slide, ensuring the transverse positioning of the glass slide and preventing the glass slide from shifting laterally. Four sets of through-type mounting holes are opened at the corresponding corner positions, which are completely matched with the number, diameter and position of the upper structure (1).

[0022] The lower structure (3) serves as the bottom support and equipment adapter of the device. Its overall horizontal dimension is 40mm, which matches the horizontal dimension of the upper structure (1), forming a symmetrical structural support to enhance the overall stability of the component. The vertical dimension on both sides is 19mm. The upper surface is a flat planar support surface that fully fits the bottom surface of the glass slide, providing stable support for the bottom of the glass slide. The lower surface is a fitting structure that fits the laboratory cleaning equipment testing station, allowing for precise fitting with the mounting surface of the cleaning equipment testing station, thus enabling stable placement of the component on the cleaning equipment. Four sets of through mounting holes matching the middle structure (2) are provided at the corresponding corner positions.

[0023] The upper structure (1), middle structure (2), and lower structure (3) are precisely aligned through four sets of four corner mounting holes. Adjacent structures are connected by stainless steel threaded rods (6) passing through corresponding mounting holes and tightened with hexagonal nuts (7) to achieve a detachable fixed connection. The diameter of the threaded rod (6) is precisely matched with the mounting hole diameter, and the length is matched with the total thickness of the three stacked components. The thread specifications of the nut (7) and the threaded rod (6) are perfectly matched. After tightening, the three structures can be tightly stacked, ensuring the overall structural strength and connection stability of the installation component and preventing structural loosening during the test. At the same time, the installation component can also adopt a rigid plastic integrated injection molding design according to the model of the laboratory cleaning equipment, the test frequency, and the test scenario requirements. The integrated structure has no splicing gaps, the overall structural strength is higher, the vibration resistance is better, and it is suitable for harsh test scenarios such as heavy oil stain removal test and high speed vibration test.

[0024] (ii) Cylindrical protective enclosure The slide mounting assembly provides basic physical protection and isolation from the test environment. It is a hollow cylindrical cover (5) with an open top and no additional top cover structure. Its structural design is adapted to the actual operational needs of laboratory cleaning tests. The specific design is as follows: Made of 304 stainless steel, it is oil-resistant, corrosion-resistant, and easy to clean, making it suitable for contact with various cleaning reagents and oily liquids in cleaning tests, thus extending its service life. The inner cavity size is adapted to the overall shape of the slide mounting assembly, which can completely accommodate the slide mounting assembly within the inner cavity of the cover, achieving all-round protection for the mounting assembly and the slide. The open top design facilitates the installation, removal, and operation of the glass slides during the test, without affecting the normal conduct of the cleaning test.

[0025] During the test, the assembled mounting assembly with the glass slide installed is placed inside the cylindrical protective housing, and then the entire assembly is placed on the test station of the laboratory cleaning equipment to carry out the cleaning test.

[0026] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides an apparatus for mounting glass slides on laboratory cleaning equipment according to the present invention. The scope of protection of the present invention is not limited to the following embodiments.

[0027] Example 1: This embodiment provides a detachable device for mounting glass slides in laboratory cleaning equipment. The device includes a glass slide mounting assembly and a cylindrical protective housing (5).

[0028] Slide mounting assembly fabrication and assembly: The upper structure (1), middle structure (2), and lower structure (3) are all made of rigid PP plastic. Four sets of holes with a diameter of 3mm are evenly distributed at the four corners of each of the three structures. The through-hole mounting hole; place the middle structure (2) stably on the upper end face of the lower structure (3), so that the mounting holes of the two are precisely aligned, insert the stainless steel threaded rod (6) (diameter 3mm) through the mounting holes of the lower and middle structures, and screw on the hexagonal nut (7) for initial fixation; vertically embed the laboratory conventional glass slide into the annular support limiting space of the middle structure (2), so that the bottom of the glass slide is closely attached to the planar support surface of the lower structure (3), and the top is closely attached to the lower surface of the upper structure (1); then place the upper structure (1) on the upper end face of the middle structure (2), so that the mounting hole of the upper structure (1) is precisely aligned with the threaded rod (6), and continue to tighten the hexagonal nut (7) so that the three structures are tightly stacked, and complete the embedded and stable installation of the glass slide in the mounting assembly.

[0029] Protective Assembly and Testing: The assembled and installed slide mounting assembly is placed stably in the inner cavity of a cylindrical protective enclosure (5) made of 304 stainless steel, ensuring that the mounting assembly does not directly collide with the inner wall of the enclosure. The protective enclosure containing the mounting assembly is then placed on the test station of the laboratory's conventional cleaning equipment, ensuring that the lower end face of the lower structure (3) is precisely aligned with the mounting surface of the test station of the cleaning equipment. After completion, the cleaning equipment is started to conduct cleaning tests such as heavy oil stain removal. After the test is completed, the equipment is turned off, and the protective enclosure and mounting assembly are removed together. The nut (7) is unscrewed, the threaded rod (6) is pulled out, and the upper structure (1) and middle structure (2) are disassembled in sequence to remove the slide. Each component of the device can be cleaned, disinfected, and reused. If a component is damaged, it can be replaced individually, further reducing the cost of use.

[0030] Example 2: This embodiment provides an integrated device for mounting glass slides on laboratory cleaning equipment. The device includes a glass slide mounting assembly and a cylindrical protective housing (5), which is suitable for high-intensity, high-frequency, and high-vibration cleaning test scenarios in laboratories.

[0031] Fabrication of slide mounting components: The upper structure (1), middle structure (2) and lower structure (3) are integrally injection molded from rigid ABS plastic, with no splicing gaps, high structural strength and good vibration resistance; the dimensions of each structure are consistent with those of Example 1, namely, the upper structure (1) has an edge spacing of 1mm and an overall horizontal dimension of 40mm, the middle structure (2) has a longitudinal dimension of 26mm and a horizontal single-sided dimension of 29mm, and the lower structure (3) has an overall horizontal dimension of 40mm and a longitudinal double-sided dimension of 19mm. After integral molding, they are enclosed to form a closed mounting cavity (4) that precisely matches the conventional laboratory slides.

[0032] Protective Assembly and Testing: Vertically embed a standard laboratory slide into the mounting cavity (4) of the integrated mounting assembly, utilizing the omnidirectional positioning of the mounting cavity to achieve stable installation of the slide; place the integrated mounting assembly with the slide installed into the inner cavity of the 304 stainless steel cylindrical protective housing (5), and then place the entire assembly together on the test station of the laboratory customized cleaning equipment. Start the equipment to conduct the cleaning test. After the test is completed, directly remove the slide from the mounting cavity (4). The mounting assembly and protective housing can be cleaned, disinfected, and reused as a whole.

[0033] In actual manufacturing, the device of the present invention can be finely adjusted according to the specific size of the laboratory slide, the test station specifications of the cleaning equipment and the test requirements. The size of the mounting hole and the diameter of the mounting cavity can be finely adjusted. As long as the mounting cavity (4) is accurately matched with the slide and the mounting components can be stably placed in the inner cavity of the protective housing and the test station of the cleaning equipment, they are all within the protection scope of the present invention.
