Description

Technical Field

[0001] This utility model relates to the field of pallet technology, and in particular to a corrosion-resistant and leak-proof pallet. Background Technology

[0002] When storing test tubes or reagent bottles, they are usually placed in cabinets. Like test tubes, reagent bottles are placed in special trays with multiple holes. The reagent bottles and test tubes are inserted into the holes for fixation. Because these containers may contain corrosive liquids or need to prevent leakage, special tray designs are required for storage.

[0003] Chinese Patent CN219313319U discloses a corrosion-resistant and leak-proof tray, relating to the field of tray technology. Specifically, it includes a base plate with a surrounding plate vertically mounted on its top edge. Both the base plate and the surrounding plate are made of corrosion-resistant material. A placement plate is placed within the space enclosed by the surrounding plate and the base plate. The surface of the placement plate has matrix-arranged receiving openings. The placement plate is also made of corrosion-resistant material. Multiple positioning posts are installed on the bottom edge of the placement plate, and these posts are placed on the base plate. Placement holes are provided at the four top corners of the base plate. Magnets are installed in the placement holes and at the bottom of the positioning posts, attracting each other. In use, the edge of the placement plate can move up and down within the surrounding plate, and the positioning posts are positioned in the placement holes to prevent the placement plate from shaking. Simultaneously, the placement plate is easy to remove, clean, and install.

[0004] However, when using the above-mentioned solutions with trays, the single-layer PP plastic has low strength and impact resistance, making it easy to deform or be damaged by heavy loads or impacts, affecting the structural stability of the tray. Furthermore, when fixing the base plate with magnets, the magnets can interfere with some reagents containing ferromagnetic particles. These particles will move, aggregate, or precipitate under the influence of the magnetic field, thereby changing the uniformity and concentration of the reagent and affecting the accuracy of the experimental results. Therefore, a corrosion-resistant and leak-proof tray is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the technical problems of single-layer PP plastic having low strength and impact resistance, making it prone to deformation or damage under heavy loads or impacts, and the fact that magnets can interfere with reagents containing ferromagnetic particles when fixing the base plate, thereby altering the uniformity and concentration of the reagents, this application provides a corrosion-resistant and leak-proof tray.

[0006] This utility model proposes a corrosion-resistant and leak-proof tray, which includes a frame. The upper surface of the frame is provided with a fixing mechanism, which includes a spring and a sliding plate. The elastic deformation of the spring drives the sliding plate to reset.

[0007] The lower surface of the frame is provided with a support mechanism, which includes a reinforcing layer that enhances the load-bearing capacity of the frame through its high strength characteristics.

[0008] Preferably, the fixing mechanism further includes a fixing plate, which is slidably connected to the inner wall of the frame. The upper surface of the fixing plate has test tube holes, and the fixing plate is made of high-density polyethylene.

[0009] Preferably, a handle is fixedly installed on the upper surface of the fixed plate, and the two sliding plates are slidably inserted into the grooves on both sides of the fixed plate.

[0010] Preferably, a plurality of springs are respectively fixedly installed in the grooves on both sides of the fixed plate, and one end of the spring is fixedly installed with one end of the sliding plate.

[0011] Preferably, the spring is made of stainless steel, and the inner walls on both sides of the frame are provided with a limiting groove with a semi-circular cross-section, and the arc surface of the sliding plate is slidably connected to the inner wall of the limiting groove.

[0012] Preferably, the support mechanism further includes a support leg with an anti-slip pad, the support leg being fixedly installed on the lower surface of the frame, and positioning grooves being provided on the upper surface of the four corners of the frame, the support leg being slidably inserted into the inner wall of the groove of the positioning groove, and the support leg being made of glass fiber reinforced plastic.

[0013] Preferably, the reinforcing layer is fixedly bonded to the inner wall of the groove of the frame, the reinforcing layer is made of glass fiber reinforced plastic, and the frame is made of high-density polyethylene.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By setting up a fixing mechanism, the sliding plate is driven to reset. The fixing plate and handle are fixedly installed to facilitate the movement and handling of the fixing plate by the staff. The sliding plate is slidably inserted into the fixing plate, which fixes it without affecting its movement. The spring is fixedly installed to the fixing plate and the sliding plate respectively, so that the sliding plate can be reset and locked into the limiting groove after it moves. This solves the technical problem that when using a tray, the base plate is fixed by a magnet. The magnet will interfere with some reagents containing ferromagnetic particles. These particles will move, aggregate or precipitate under the action of the magnetic field, thereby changing the uniformity and concentration of the reagent and affecting the accuracy of the experimental results.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A corrosion-resistant and leak-proof tray includes a frame 1. A fixing mechanism is provided on the upper surface of the frame 1. The fixing mechanism includes a spring 4 and a sliding plate 31. The elastic deformation of the spring 4 drives the sliding plate 31 to reset.

[0025] To enable the fixing plate 2 to withstand a certain degree of impact and pressure, the fixing mechanism also includes a fixing plate 2, which is slidably connected to the inner wall of the frame 1. A test tube hole 21 is provided on the upper surface of the fixing plate 2. The fixing plate 2 is made of high-density polyethylene. The fixing plate 2 is slidably connected to the frame 1, which fixes it without affecting its removal. The diameter of the test tube hole 21 can be determined according to the diameter of commonly used test tubes. The fixing plate 2 is made of high-density polyethylene, which has high strength and toughness, can withstand a certain degree of impact and pressure, is not easily damaged, and has good corrosion resistance to most chemical reagents, making it suitable for storing corrosive liquids.

[0026] To facilitate the movement and handling of the fixed plate 2 by staff, a handle 3 is fixedly installed on the upper surface of the fixed plate 2. Two sliding plates 31 are respectively slidably inserted into the grooves on both sides of the fixed plate 2. The fixed plate 2 is fixedly installed with the handle 3, which makes it convenient for staff to move and handle the fixed plate 2. The sliding plates 31 are slidably inserted into the fixed plate 2, which fixes it without affecting its movement. The handle 3 can be made of nylon, which has excellent wear resistance and can be used for a long time without being easily worn. The sliding plates 31 can be made of polytetrafluoroethylene, which has an extremely low coefficient of friction and excellent chemical corrosion resistance.

[0027] In order to reset the sliding plate 31 and lock it into the limiting groove 5, multiple springs 4 are fixedly installed in the grooves on both sides of the fixed plate 2. One end of the spring 4 is fixedly installed with one end of the sliding plate 31. The springs 4 are fixedly installed with the fixed plate 2 and the sliding plate 31 respectively, so that the sliding plate 31 can be reset and locked into the limiting groove 5 after it moves.

[0028] To ensure the stability and guidance of the sliding plate 31 during movement, the spring 4 is made of stainless steel. The inner walls of both sides of the frame 1 are provided with semi-circular cross-section limiting grooves 5. The arc surface of the sliding plate 31 is slidably connected to the inner wall of the limiting grooves 5. The stainless steel material of the spring 4 provides high strength and toughness, enabling it to withstand greater forces without easily deforming or breaking, thus ensuring the stability of the spring 4 during long-term use. The limiting grooves 5 on the frame 1, slidably connected to the sliding plate 31, ensure the stability and guidance of the sliding plate 31 during movement.

[0029] By setting a fixing mechanism, the sliding plate 31 is driven to reset. The fixing plate 2 and the handle 3 are fixedly installed and fixed to it, which facilitates the movement and handling of the fixing plate 2 by the staff. The sliding plate 31 is slidably inserted into the fixing plate 2, which fixes it without affecting its movement. The spring 4 is fixedly installed to the fixing plate 2 and the sliding plate 31 respectively, so that after the sliding plate 31 moves, it resets and locks with the limiting groove 5. This solves the technical problem that when using a tray, the magnet fixes the bottom plate, and the magnet will interfere with some reagents containing ferromagnetic particles. These particles will move, aggregate or precipitate under the action of the magnetic field, thereby changing the uniformity and concentration of the reagent and affecting the accuracy of the experimental results.

[0030] In order to improve the load-bearing capacity of frame 1, a support mechanism is provided on the lower surface of frame 1. The support mechanism includes a reinforcing layer 7, which improves the load-bearing capacity of frame 1 through its high strength characteristics.

[0031] To ensure the leg 6 has good elasticity and wear resistance, the support mechanism also includes a leg 6 with an anti-slip pad. The leg 6 is fixedly installed on the lower surface of the frame 1. Positioning grooves 61 are provided on the upper surface of the four corners of the frame 1. The leg 6 is slidably inserted into the inner wall of the groove of the positioning groove 61. The leg 6 is made of glass fiber reinforced plastic. The leg 6 is fixedly installed to the frame 1 and secured. The positioning groove 61 is provided on the frame 1, and the leg 6 is slidably inserted into it. When the frames 1 need to be stacked, the leg 6 on one frame 1 can be inserted into the positioning groove 61 on another frame 1. The height of the positioning groove 61 and the leg 6 can be set according to actual needs to ensure that the lower surface of the frame 1 does not touch the top of the test tube. The anti-slip pad on the leg 6 can be made of polyurethane, which has good elasticity and wear resistance.

[0032] To reduce the risk of deformation or damage to frame 1, reinforcing layer 7 is fixedly bonded to the inner wall of the groove in frame 1. Reinforcing layer 7 is made of glass fiber reinforced plastic, while frame 1 is made of high-density polyethylene. The reinforcing layer 7 is fixedly bonded to frame 1, thus securing it in place. The glass fiber reinforced plastic of reinforcing layer 7 has high strength and good impact resistance, effectively dispersing and bearing external loads and reducing the risk of deformation or damage to frame 1. The high-density polyethylene of frame 1 has excellent chemical corrosion resistance, resisting the erosion of chemicals such as acids, alkalis, and salts, making it suitable for various complex environments.

[0033] By setting up a support mechanism, the load-bearing capacity of frame 1 is improved. When frames 1 need to be stacked, the support leg 6 on one frame 1 can be inserted into the positioning groove 61 on another frame 1. The reinforcing layer 7 is fixedly bonded to the frame 1. The material of the reinforcing layer 7 is glass fiber reinforced plastic, which has high strength and good impact resistance. It can effectively disperse and bear external loads, reduce the risk of deformation or damage to frame 1, and solve the technical problem that single-layer PP plastic has low strength and impact resistance, and is easily deformed or damaged due to heavy load or impact, affecting the structural stability of the pallet.

[0034] Working principle: When it is necessary to place a test tube, the staff moves the fixing plate 2 by the handle 3, so that it moves on the inner wall of the frame 1. The sliding plate 31 on the fixing plate 2 is squeezed by the inner wall of the frame 1 and retracts into the groove of the fixing plate 2. When it moves to the limiting groove 5, the spring 4 makes the sliding plate 31 return to the original position and lock it with the limiting groove 5, thereby fixing the fixing plate 2 firmly in the frame 1. Then the test tube is placed in the test tube hole 21 opened on the fixing plate 2.

[0035] When multiple frames 1 need to be stacked to facilitate the storage of a large number of test tubes, the staff slides the support leg 6 on another frame 1 into the positioning groove 61 of the frame 1 where the test tubes are placed. The anti-slip pad on the support leg 6, which contacts the ground or the placement surface, can prevent the frame 1 from sliding and enhance stability. The reinforcing layer 7 is made of glass fiber reinforced plastic, which has high strength and good impact resistance, and can effectively disperse and bear external loads, reducing the risk of deformation or damage to the frame 1. The frame 1 is made of high-density polyethylene, which has excellent chemical corrosion resistance and can resist the erosion of chemicals such as acids, alkalis, and salts, making it suitable for various complex environments.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
