Description

Technical Field

[0001] This application relates to the field of drain rack technology, and in particular to a drain rack for washing laboratory utensils. Background Technology

[0002] Laboratory glassware must be thoroughly dried after cleaning to avoid residual moisture contaminating subsequent experiments.

[0003] Common methods currently include air drying (which takes up counter space and is inefficient), drying (which is energy-intensive and not suitable for heat-sensitive dishes), or simple mesh racks for draining (which are easy to tip over and have poor drainage).

[0004] In recent years, some laboratories have adopted multi-layer stainless steel rack structures, but these suffer from problems such as low space utilization and poor compatibility with glassware. With the upgrading of laboratory safety standards, the requirements for dust prevention and cross-contamination prevention in glassware storage are becoming increasingly stringent. Existing drain racks generally suffer from incomplete drainage. To further optimize the drainage effect of drain racks, a new drain rack for washing laboratory glassware is proposed. Utility Model Content

[0005] The purpose of this application is to provide a drain rack for washing laboratory utensils, which achieves a combination of efficient drainage, versatility, dust prevention, and convenient operation through structural optimization, thus solving the problems mentioned in the background art.

[0006] This application provides a laboratory glassware washing rack with the following technical solution: A laboratory glassware washing rack includes a support assembly. A detachable drain assembly is installed on top of the support assembly. The drain assembly includes a drain groove and two positioning holes on both sides of the outer surface of the drain groove. A guide block is fixedly connected to the inner wall of the drain groove. Multiple drain pipes are connected to the front of the drain groove. A main drain tray is fixedly connected to the upper surface of the guide block. The main drain tray is a PP injection molded part with a 5° tilt angle. The interior of the main drain tray has evenly distributed drain holes. The outer surface of the main drain tray is equipped with radially distributed branch guide rods. The outer surface of each branch guide rod has evenly distributed branch guide grooves and stepped annular grooves. A dust cover is installed on the exterior of the drain assembly.

[0007] By adopting the above technical solution, the water collection function of the drainage trough and the guiding effect of the guide block are combined with the drainage holes of the main drain tray to form a "layered flow guiding system". The branch guide rod and branch guide groove are adapted to slender vessels such as test tubes and droppers, while the stepped annular groove stably supports large-mouthed vessels such as beakers and funnels, realizing simultaneous drainage of multiple types of vessels. The drain pipe can be quickly discharged, solving the problem of "dispersed drainage and single vessel compatibility" of traditional drain racks, and improving drainage efficiency and compatibility.

[0008] Preferably, the support assembly includes a base and four columns fixedly connected to the upper surface of the base. A top plate is provided above the base, and the tops of the four columns are fixedly connected to the bottom surface of the top plate.

[0009] By adopting the above technical solution, the base, columns and top plate form a stable frame, providing vertical support for the device, avoiding tipping due to center of gravity shift during the drainage process, solving the problem of "poor stability and easy tipping" of traditional simple frames, and ensuring the reliability of device operation.

[0010] Preferably, a lead screw is rotatably sleeved on the upper surface of the base, the top of the lead screw is rotatably sleeved in the inner wall of the top plate, and a knob is fixedly connected to the top end of the lead screw.

[0011] By adopting the above technical solution, the screw drive combined with the top knob operation design can accurately control the height of the adjustable shelf. Compared with the traditional buckle adjustment, it has the advantages of "high adjustment accuracy and convenient operation" and meets different usage needs.

[0012] Preferably, the outer surface of the lead screw is threaded with an adjustable shelf, and the inner wall of the adjustable shelf is slidably sleeved on the outer surface of the four columns.

[0013] By adopting the above technical solution, the adjustable shelf uses a screw as the power source and the column as the sliding guide to achieve smooth guidance during the lifting process, avoid tilting of the adjustable shelf, ensure that the drain assembly remains horizontal after installation, and ensure a stable drain path with no water accumulation.

[0014] Preferably, a vertical plate is fixedly connected to the upper surface of the adjustable shelf, and the top of the vertical plate is hinged to the dust cover by a pin.

[0015] By adopting the above technical solution, the upright plate provides hinged support for the dust cover, allowing the dust cover to be rotated around the pin shaft, realizing the function of convenient use, effectively reducing the risk of microbial contamination, and the transparent design facilitates inventory management.

[0016] Preferably, two positioning rods are slidably sleeved on both sides of the bottom of the upright plate, and the size and position of the positioning rods correspond to the size and position of the positioning holes.

[0017] By adopting the above technical solution, the positioning rod and positioning hole adopt a "precise fit + sliding plug" design, which can quickly complete the installation and disassembly of the drainage component, facilitate regular cleaning or replacement of the component, solve the problem of "inconvenient cleaning and maintenance of traditional fixed connection structure", and improve the maintenance efficiency of the device.

[0018] Preferably, one end of each positioning rod is fixedly connected to a lever, the outer surface of each lever is fixedly connected to a telescopic spring, and the other end of each telescopic spring is fixedly connected to the outer surface of the upright plate.

[0019] By adopting the above technical solution, pulling the lever drives the positioning rod to move, and the telescopic spring provides the rebound force to keep the positioning rod locked in a normal state, realizing the convenient operation of "easy disassembly and assembly" while ensuring connection stability, and solving the problems of "complex operation and loose connection" in traditional disassembly and assembly structures.

[0020] Preferably, mounting bases are fixedly connected to all four corners of the base.

[0021] By adopting the above technical solution, the mounting base at the corner of the base can be fixed to the experimental table with bolts, which further enhances the stability of the device and avoids tipping over due to collision or load. It is especially suitable for high-frequency use scenarios, solves the problem of "the device is easy to move and there are great safety hazards", and improves safety and reliability.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This laboratory glassware washing rack features a tiered drainage system formed by a drainage component, a drainage channel, a guide block, a 5° inclined main drain tray, and drainage holes. The radial branch guide rods and stepped annular grooves accommodate various types of glassware, including test tubes and beakers. A quick-release structure for the positioning rods and holes, combined with a lever and telescopic spring, allows for easy disassembly and cleaning of the drainage component. A hinged dust cover on the upright plate provides dust protection, reducing the risk of contamination. A reinforced mounting device on the base ensures stability and prevents tipping. Compared to existing technologies, this rack effectively solves problems such as low drainage efficiency, limited glassware compatibility, cumbersome maintenance, insufficient stability, and lack of dust protection, simultaneously improving drainage efficiency, ease of operation, and safety.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0033] Example 1: A drain rack for washing laboratory utensils, referring to... Figure 1 , Figure 2 and Figure 4 The system includes a support assembly 1, on which a detachable drain assembly 2 is mounted. The drain assembly 2 includes a drain channel 201 and two positioning holes 202 on both sides of the outer surface of the drain channel 201. The positioning holes 202 are adapted to the positioning structure of the support assembly 1 to enable quick assembly and disassembly of the drain assembly 2, facilitating cleaning and maintenance. A guide block 203 is fixedly connected to the inner wall of the drain channel 201, and multiple drain pipes 204 are connected to the front of the drain channel 201. The drain pipes 204 enable rapid drainage of accumulated water, solving the problems of scattered drainage and low efficiency. The guide block 203... The upper surface is fixedly connected to a main drain tray 205, which is a PP injection molded part with a 5° tilt angle. The 5° tilted main drain tray 205 uses gravity to assist the water flow to converge. Combined with the corrosion resistance of PP material, it improves the drainage efficiency and component durability. The interior of the main drain tray 205 has evenly distributed drainage holes 206, which form a multi-layer drainage channel, allowing residual water in the container to quickly penetrate into the drain groove 201, enhancing the drainage effect. The guide block 203 can guide and converge the water flow in the main drain tray 205, optimize the drainage path, and avoid water accumulation.

[0034] Reference Figure 2 , Figure 4 and Figure 6The outer surface of the main drain tray 205 is equipped with radially distributed branch guide rods 207. The radially distributed branch guide rods 207 expand the drain space, adapting to the simultaneous draining of multiple types of vessels and improving space utilization. The outer surface of each branch guide rod 207 is provided with evenly distributed branch guide grooves 208 and stepped annular grooves 209. The branch guide grooves 208 are adapted to slender vessels such as test tubes, while the stepped annular grooves 209 stably support large-mouthed vessels such as beakers, solving the problem of single vessel compatibility and realizing classified draining. The outside of the drain assembly 2 is equipped with a dust cover 3, which forms a dustproof shield for the vessels during the draining process, reducing the risk of cross-contamination and meeting the cleanliness requirements of the laboratory.

[0035] Example 2: A drain rack for washing laboratory utensils, referring to... Figure 1 , Figure 2 and Figure 3 Based on the same concept as Embodiment 1 above, this embodiment proposes a support assembly 1 including a base 101 and four columns 102 fixedly connected to the upper surface of the base 101. A top plate 103 is provided above the base 101, and the tops of the four columns 102 are fixedly connected to the bottom surface of the top plate 103. The base 101, columns 102, and top plate 103 form a stable frame, providing vertical support for the device and preventing it from tipping over due to center of gravity shift during the drainage process. This solves the problem of "poor stability and easy tipping" of traditional simple frames, ensuring the reliability of the device operation. A lead screw 104 is rotatably sleeved on the upper surface of the base 101, and the top of the lead screw 104 is rotatably sleeved in the inner wall of the top plate 103. The top of the 04 is fixedly connected to a knob 110. The screw drive of the lead screw 104, combined with the operation design of the top knob 110, can precisely adjust the height of the adjustable shelf 105. Compared with the traditional buckle adjustment, it has the advantages of "high adjustment accuracy and convenient operation" to meet different usage needs. The outer surface of the lead screw 104 is threadedly connected to the adjustable shelf 105. The inner wall of the adjustable shelf 105 is slidably sleeved on the outer surface of the four columns 102. The adjustable shelf 105 uses the lead screw 104 as the power source and the columns 102 as the sliding guide to achieve smooth guidance during the lifting process, avoid the adjustable shelf 105 from tilting, and ensure that the drain assembly 2 always remains horizontal after installation, ensuring a stable drain path and no water accumulation residue.

[0036] Reference Figure 2 , Figure 3 and Figure 4An adjustable shelf 105 has a vertical plate 106 fixedly connected to its upper surface. The top of the vertical plate 106 is hinged to the dust cover 3 via a pin. The vertical plate 106 provides hinge support for the dust cover 3, allowing the dust cover 3 to rotate around the pin for convenient use. This effectively reduces the risk of microbial contamination, and the transparent design facilitates inventory management. Two positioning rods 107 are slidably fitted on both sides of the bottom of the vertical plate 106. The dimensions and positions of the positioning rods 107 correspond to the dimensions and positions of the positioning holes 202. The positioning rods 107 and the positioning holes 202 adopt a "precise fit + sliding insertion" design, which allows for quick installation and disassembly of the drain assembly 2. This facilitates regular cleaning or replacement of the assembly, solving the problem of inconvenient cleaning and maintenance of traditional "fixed connection structures," and improving the maintenance efficiency of the device. One end of each positioning rod 107... Each plate is fixedly connected with a lever 108, and a telescopic spring 109 is fixedly connected to the outer surface of each lever 108. The other end of each telescopic spring 109 is fixedly connected to the outer surface of the upright plate 106. Pulling the lever 108 drives the positioning rod 107 to move, and the telescopic spring 109 provides a rebound force to keep the positioning rod 107 locked in a normal state, realizing convenient operation of "easy disassembly and assembly" while ensuring connection stability. This solves the problems of "complex operation and loose connection" in traditional disassembly and assembly structures. Mounting seats 111 are fixedly connected to the four corners of the base 101. The mounting seats 111 at the corners of the base 101 can be fixed to the experimental table with bolts to further enhance the stability of the device and avoid tipping due to collision or load. It is especially suitable for high-frequency use scenarios, solving the problems of "easy device displacement and great safety hazards" and improving safety and reliability.

[0037] The implementation principle of this application embodiment is as follows: First, the device is fixed to the experimental table with bolts through the mounting seats 111 at the four corners of the base 101. The stable frame constructed by the base 101, the column 102 and the top plate 103 provides a vertical support foundation for the whole. Rotating the knob 110 above the top plate 103 drives the screw 104 to drive the adjustable shelf 105, which is slidably sleeved on the inner wall of the column 102, to accurately raise and lower, so as to meet the usage requirements of different heights. The column 102 simultaneously provides guidance for the adjustable shelf 105 to ensure that it is always horizontal. The vertical plate 106 on the upper surface of the adjustable shelf 105 is hinged to the dust cover 3 by a pin, which enables the dust cover 3 to be flipped open and closed for easy use. When installing the drain assembly 2, pull the lever 108 at the bottom of the vertical plate 106 to stretch the telescopic spring 109 and move the positioning rod 107 outward. After aligning the positioning hole 202 of the drain assembly 2 with the positioning rod 107, release the lever 108. The rebound force of the telescopic spring 109 pushes the positioning rod 107 into the positioning hole 202, completing the quick-release connection. When disassembling and cleaning, repeat the lever 108 operation to unlock. When placing the vessels, test tubes, droppers and other slender vessels are inserted into the branch guide rod 207 and can be drained through the branch guide groove 208. Beakers, funnels and other large-mouthed vessels are inverted in the stepped annular groove 209 and stably supported by the groove structure. During the draining stage, residual water on the surface of the vessel flows down the wall and converges into the main draining tray 205 via the branch guide channel 208 and the stepped annular channel 209. The main draining tray 205 is designed with a 5° inclined PP injection molding part, and with the draining holes 206 evenly distributed on the inner wall, it accelerates the water flow through and guides the water along the guide block 203 to the drain channel 201. Finally, it is quickly discharged through the drain pipe 204 connected to the front of the drain channel 201, forming a hierarchical flow path of "vessel → branch structure → main tray → drain channel → drain pipe" to avoid water accumulation.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
