Description

Technical Field

[0001] This application relates to the technical field of testing equipment, and in particular to a rapid testing kit for metalworking fluids. Background Technology

[0002] As an important auxiliary medium in machining processes, metalworking fluids play vital roles in cooling, lubrication, cleaning, and rust prevention. To ensure the proper use of metalworking fluids, workers need to regularly test their rust-preventive properties and bacterial counts.

[0003] A search revealed Chinese Patent Publication No. CN102759503B, which discloses a rapid testing kit for metalworking fluids. This kit primarily addresses the problem that existing technologies cannot conveniently and promptly test the rust prevention level and bacterial content of in-use metalworking fluids at the point of use or while traveling. The invention employs a design comprising a lid and a body, both filled with flexible material. The flexible material has slots for holding a constant temperature box, a rust prevention test box, a standard iron filings box, and bacterial testing strips. The constant temperature box includes a lid and a body, which are hinged and interlocked. The body comprises an outer shell and an inner shell, with an insulation layer between them. A DC power supply is located within the insulation layer. A heating plate is positioned between the bottom of the inner shell and the insulation layer. At least one slot is located inside the body, and a thermocouple is positioned between the slot and the heating plate. The outer shell has a switch and a plug. This design allows for timely and convenient testing of the rust prevention performance and bacterial content of metalworking fluids.

[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: because multiple bacterial test strips and rust prevention test boxes are required, workers need to repeatedly perform operations such as opening the lid, filling the liquid, sealing the lid, placing it into the constant temperature box, and taking it out of the constant temperature box, which affects the testing efficiency of metalworking fluids. Therefore, improvements are needed. Summary of the Invention

[0005] To improve the detection efficiency of metalworking fluids, this application provides a rapid detection kit for metalworking fluids.

[0006] The present application provides a rapid testing box for metalworking fluids, which adopts the following technical solution: A rapid testing box for metalworking fluids includes a box body with an open top and a box cover that can be snapped down at the open top of the box body. The box body is provided with a constant temperature box and a storage box arranged in sequence along the horizontal direction. The top of the storage box is provided with several storage cavities, and the storage cavities contain bacterial testing strips or rust prevention test boxes with an open top. The top of the constant temperature box is provided with several constant temperature cavities for placing bacterial testing strips or rust prevention test boxes.

[0007] The bottom of the lid is rotatably connected to a rotating plate that flips on a vertical plane. The two ends of the rotating plate are located directly above the storage cavity and the constant temperature cavity, respectively, and can both be flipped to the top of the rotation axis of the rotating plate. Several counterweight units are slidably connected to the bottom of the rotating plate in a direction parallel to the lower surface of the rotating plate. The sliding direction of the counterweight units is parallel to the flipping plane of the rotating plate.

[0008] The counterweight unit is rotatably connected to a cover that flips in the vertical plane. The cover can be fastened to the top opening of the bacterial test strip or the rust prevention test box.

[0010] Optionally, one of the slide rods has a limiting groove and a slot spaced vertically on its side wall, and a limiting rod that can be slidably embedded in the limiting groove and slot is slidably connected to the box body in the horizontal direction; when the box cover is fastened to the open part of the box body, the limiting rod can be embedded in the limiting groove; when the bacterial test strip and the rust prevention test box move to the top of the constant temperature box and the storage box, the limiting rod can be embedded in the slot.

[0011] Optionally, the end of the limiting rod facing the slide rod is hemispherical, the depth of the limiting groove is less than or equal to the radius of that end of the limiting rod, and the depth of the slot is greater than the radius of that end of the limiting rod; the limiting rod is connected to the housing by a spring, and the spring is used to cause the limiting rod to be inserted into the limiting groove or slot.

[0012] Optionally, the middle part of the rotating plate is rotatably connected to the bottom of the box cover via a horizontal shaft, and both ends of the rotating plate are connected to pull rings via pull ropes that slide through the box cover, with the pull rings located above the box cover.

[0013] Optionally, multiple bacterial testing strips and rust prevention test boxes are arranged sequentially along the sliding direction of the counterweight unit. Each bacterial testing strip and rust prevention test box is connected to a counterweight unit through a limiting unit and a cover. The friction between the counterweight unit near the middle of the rotating plate and the rotating plate is less than the friction between the counterweight unit near the end of the rotating plate and the rotating plate.

[0014] Optionally, one of the pull ropes is located directly above the storage cavity and connected to an elastic ball, and the lid is provided with several positioning grooves arranged vertically for the elastic ball to engage.

[0030] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0031] This application discloses a rapid testing kit for metalworking fluids. For example... Figure 1 and Figure 2 As shown, a rapid testing box for metalworking fluid includes a box body 1 and a box cover 11. The top of the box body 1 is open, and the box cover 11 can be snapped down onto the open part of the box body 1, thereby realizing the opening and closing of the open part of the box body 1.

[0032] The box 1 is equipped with a constant temperature box 2 and a storage box 3 arranged in a horizontal direction. In this embodiment, the constant temperature box 2 and the storage box 3 are arranged close to each other on the left and right. The top of the storage box 3 is provided with a number of storage cavities 31 arranged in a mesh pattern. The storage cavities 31 contain bacterial testing strips 4 or rust prevention test boxes 5 with open tops. In this embodiment, there are 6 bacterial testing strips 4 and 6 rust prevention test boxes 5.

[0033] The receiving cavity 31 can store the bacterial test strip 4 and the rust prevention test box 5. The metalworking fluid can be fed through the top opening of the bacterial test strip 4 or the rust prevention test box 5. The top of the constant temperature box 2 is provided with several constant temperature chambers 21 arranged in a mesh pattern. The number of constant temperature chambers 21 is the same as the number of receiving cavities 31. The worker can put the bacterial test strip 4 or the rust prevention test box 5 after feeding into the constant temperature chamber 21. The constant temperature chamber 21 can keep the bacterial test strip 4 and the rust prevention test box 5 at a specified temperature so as to test the rust prevention performance and bacterial content of the metalworking fluid.

[0034] like Figures 2 to 4 As shown, the bottom of the box cover 11 is provided with a rotating plate 12 that can be flipped in the vertical plane. The middle part of the rotating plate 12 is rotatably connected to the bottom of the box cover 11 through a horizontal shaft 121. The two ends of the rotating plate 12 are located directly above the storage cavity 31 and the constant temperature cavity 21, respectively, and can both be flipped to the top of the rotation axis of the rotating plate 12.

[0035] The bottom of the rotating plate 12 is provided with a number of dovetail grooves 111. In this embodiment, there are four dovetail grooves 111 arranged from front to back. The length direction of the dovetail grooves 111 is parallel to the flipping plane of the rotating plate 12. A number of counterweight units 6 are slidably embedded in the dovetail grooves 111, arranged in sequence along the length direction of the dovetail grooves 111, so as to realize the sliding connection between the counterweight units 6 and the box cover 11.

[0036] The counterweight unit 6 includes a dovetail block 61 made of cast metal. The bottom of the dovetail block 61 is rotatably connected to a cover 62 that can be flipped on a vertical surface. The bacterial test strip 4 and the rust prevention test box 5 are slidably connected to the cover 62 through a limiting unit 7.

[0037] Before the metalworking fluid is tested, the bacterial test strip 4 and the rust prevention test box 5 are placed in the storage cavity 31, with the end of the rotating plate 12 located directly above the storage cavity 31 being the lower end. When the worker pulls the box cover 11 upwards to detach it from the box body 1, the box cover 11 will drive the buckle 62 to rise through the dovetail block 61. Due to its own weight, the buckle 62 will hang vertically downwards and drive the bacterial test strip 4 and the rust prevention test box 5 to rise and detach from the storage cavity 31 through the limiting unit 7. Due to its own weight, the bacterial test strip 4 and the rust prevention test box 5 will descend a short distance and detach from the buckle 62, exposing the top opening of the bacterial test strip 4 and the rust prevention test box 5. At this time, the worker can feed the metalworking fluid into the bacterial test strip 4 and the rust prevention test box 5.

[0038] After the metalworking fluid is fed in, the worker will rotate the rotating plate 12 so that the end of the rotating plate 12 directly above the receiving cavity 31 is at its high end. At this time, the dovetail block 61 will slide down in the dovetail groove 111 due to its own weight, and through the cover 62 and the limiting unit 7, it will move the bacterial testing strip 4 and the rust prevention test box 5 to directly above the constant temperature cavity 21. Then the worker will close the box cover 11 downwards at the opening of the box body 1, and the bacterial testing strip 4 and the rust prevention test box 5 will descend and embed into the corresponding constant temperature cavity 21. The cover 62 will close downwards at the opening of the bacterial testing strip 4 or the rust prevention test box 5 so that the constant temperature cavity 21 can keep the bacterial testing strip 4 and the rust prevention test box 5 at a constant temperature.

[0039] After the metalworking fluid has been kept at a constant temperature, the worker will pull the lid 11 upwards to detach it from the chamber 1. The chamber 1 will then lift the cover 62 via the dovetail block 61. The cover 62 will then lift the microbial test strip 4 and the rust prevention test box 5 via the limiting unit 7 to detach them from the constant temperature chamber 21. The microbial test strip 4 and the rust prevention test box 5 will then descend and detach from the cover 62 due to their own weight. At this point, the worker can directly extract the metalworking fluid from the microbial test strip 4 and the rust prevention test box 5 for testing, and it is also convenient for the worker to clean the metalworking fluid from the microbial test strip 4 and the rust prevention test box 5.

[0040] After the metalworking fluid testing and cleaning are completed, the worker will rotate the rotating plate 12 so that the end of the rotating plate 12 directly above the constant temperature chamber 21 is at its high end. At this time, the dovetail block 61 will slide down in the dovetail groove 111 due to its own weight, and through the cover 62 and the limiting unit 7, it will move the bacterial testing strip 4 and the rust prevention test box 5 to directly above the storage chamber 31. Then the worker will lower the box cover 11 and fasten it at the opening of the box body 1. The bacterial testing strip 4 and the rust prevention test box 5 will be stored back in the corresponding storage chamber 31, and the cover 62 will be fastened again at the opening of the bacterial testing strip 4 and the rust prevention test box 5.

[0041] It is worth noting that workers can make notches at both ends of the rotating plate 12 that connect to the dovetail groove 111, so that the dovetail block 61 can enter and exit the dovetail groove 111 through the notches, so that workers can remove the bacterial test strip 4 and the rust prevention test box 5 for cleaning; in addition, workers can install a baffle at the notch with screws so that the baffle blocks the notch, so as to prevent the dovetail block 61 from accidentally slipping off the notch during use.

[0042] like Figure 2 and Figure 5 As shown, each of the four corners of the top of the box body 1 is provided with a sliding groove 13, and each of the four corners of the lower surface of the box cover 11 is provided with a sliding rod 14. The sliding rod 14 can slide vertically and be embedded in the corresponding sliding groove 13, so that the box cover 11 can only move up and down relative to the box body 1, so that the box cover 11 can be accurately fastened to the box body 1, and it is convenient for the bacterial test strip 4 and the rust prevention test box 5 to be accurately transferred between the storage cavity 31 and the constant temperature cavity 21.

[0043] The lower outer walls of the box body 1 are provided with air holes 15 that connect to the corresponding slide grooves 13. External air can exchange with the air in the slide grooves 13 through the air holes 15, so that the slide rod 14 can slide in the slide grooves 13. During the process of the box cover 11 falling and fastening to the opening of the box body 1 due to its own weight, the air in the slide grooves 13 will be squeezed out from the air holes 15 at a certain rate. The worker can determine the amount of air that can flow through the air holes 15 per unit time by controlling the size of the air holes 15. That is, the speed at which the box cover 11 falls due to its own weight is adjustable. This avoids the box cover 11 falling too slowly, which would affect the fastening efficiency, and also avoids the box cover 11 falling too fast, which would cause the bacterial test strip 4 and the rust prevention test box 5 to collide and be damaged.

[0044] One of the slide rods 14 has a limiting groove 141 and a slot 142 arranged at intervals on its side wall. The outer wall of the housing 1 has a connecting groove 16 extending in the horizontal direction. The connecting groove 16 is connected to one of the slide grooves 13. A limiting rod 17 is slidably embedded in the slide groove 13. One end of the limiting rod 17 facing the slide rod 14 is hemispherical. The other end of the limiting rod 17 extends out of the housing 1 and is wrapped with a spring 171. The two ends of the spring 171 are fixedly connected to the limiting rod 17 and the housing 1, respectively.

[0045] When the lid 11 is fastened to the opening of the box body 1, the spring 171 will cause the hemispherical end of the limiting rod 17 to be inserted into the limiting groove 141, so that the lid 11 is locked and fixed on the box body 1, ensuring the stability of the lid 11 when it is closed in the opening of the box body 1. Since the depth of the limiting groove 141 is less than or equal to the radius of the hemispherical end of the limiting rod 17, the worker can pull the lid 11 up to make the limiting rod 17 disengage from the limiting groove 141, so as to facilitate the transfer of the bacterial test strip 4 and the rust prevention test box 5.

[0046] When the bacterial test strip 4 and the rust prevention test box 5 slide on the rotating plate 12, the spring 171 will cause the limiting rod 17 to be inserted into the slot 142. The depth of the slot 142 is greater than the radius of the hemispherical end of the limiting rod 17, so that the box cover 11 is locked and fixed on the box body 1. That is, the worker can complete the transfer of the bacterial test strip 4 and the rust prevention test box 5 without holding the box cover 11. The worker can pull the limiting rod 17 away from the slot 142, so that the box cover 11 will fall and close the opening of the box body 1 due to its own weight.

[0047] like Figure 3 As shown, both ends of the rotating plate 12 are connected to pull rings 123 via pull ropes 122 that slide through the lid 11. The pull rings 123 are located above the lid 11. When the lid 11 is closed at the top opening of the box body 1, the worker can pull the pull rings 123 upwards, causing the pull rings 123 to rotate one end of the rotating plate 12 upwards via the pull ropes 122, thus raising the lid 11 and detaching it from the box body 1. This allows the microbial test strips 4 and the rust prevention test box 5 to be quickly transferred between the storage cavity 31 and the constant temperature cavity 21.

[0048] like Figure 4 and Figure 8 As shown, multiple bacterial testing strips 4 and rust prevention test boxes 5 are arranged sequentially along the length of the dovetail groove 111. Each bacterial testing strip 4 and rust prevention test box 5 is connected to a dovetail block 61 through a limiting unit 7 and a cover 62, that is, the bacterial testing strips 4 and rust prevention test boxes 5 have multiple rows and columns.

[0049] The roughness of each pair of adjacent dovetail blocks 61 located in the same dovetail groove 111 is different. The friction between the dovetail block 61 near the middle of the rotating plate 12 and the rotating plate 12 is less than that between the dovetail block 61 near the end of the rotating plate 12 and the rotating plate 12. Therefore, the tilt angle of the rotating plate 12 required for each pair of adjacent dovetail blocks 61 located in the same dovetail groove 111 to slide down is different. Thus, by controlling the tilt angle of the rotating plate 12, the worker can transfer different numbers of bacterial test strips 4 and rust prevention test boxes 5 from the storage cavity 31 to the constant temperature cavity 21 to suit different numbers of test samples.

[0050] like Figure 3 and Figure 6As shown, one of the pull ropes 122 is located directly above the storage cavity 31 and is connected to an elastic ball 124. The box cover 11 has several positioning slots 112 arranged vertically for the elastic balls 124 to engage. By keeping the box cover 11 still and pulling the pull rope 122, the worker can make the elastic balls 124 on the pull rope 122 engage in different positioning slots 112, thereby fixing the rotating plate 12 at different tilt angles, so that the worker can accurately transfer a specified number of bacterial test strips 4 and rust prevention test boxes 5 into the constant temperature cavity 21.

[0051] like Figure 7 and Figure 8 As shown, the limiting unit 7 includes a limiting ring 71 installed on the outer wall of the bacterial test strip 4 or the rust prevention test box 5 and at least two vertical rods 72 installed on the lower end face of the cover 62. The two vertical rods 72 slide through the same limiting ring 71 in the vertical direction, so that the bacterial test strip 4 and the rust prevention test box 5 can only be raised and lowered relative to the cover 62.

[0052] The lower end of the vertical rod 72 is threaded with a nut 73 located below the limiting ring 71. When the bacterial test strip 4 and the rust prevention test box 5 descend due to their own weight, the top openings of the bacterial test strip 4 and the rust prevention test box 5 will be exposed. At this time, the nut 73 can support the limiting ring 71, so that the bacterial test strip 4 and the rust prevention test box 5 can be raised and lowered synchronously with the cover 62 for the transfer of the bacterial test strip 4 and the rust prevention test box 5. After the worker unscrews the nut 73 from the vertical rod 72, the bacterial test strip 4 can be removed from the rust prevention test box 5 separately for cleaning and replacement of the bacterial test strip 4 and the rust prevention test box 5.

[0053] The implementation principle of a rapid metalworking fluid testing box in this application embodiment is as follows: Before the metalworking fluid is tested, the bacterial test strip 4 and the rust prevention test box 5 are placed in the storage cavity 31. The worker presses down the box cover 11 with one hand and pulls up the pull ring 123 located directly above the storage cavity 31 with the other hand, so that the elastic ball 124 is engaged in the appropriate positioning groove 112.

[0054] Then the worker will stop pressing the lid 11 and continue to pull the pull ring 123. The pull ring 123 will cause the end of the rotating plate 12 located directly above the storage cavity 31 to flip upward through the pull rope 122. The rotating plate 12 will cause the lid 11 to rise and detach from the box body 1, and drive the buckle 62 to rise through the dovetail block 61. The buckle 62 will drive the bacterial test strip 4 and the rust prevention test box 5 to rise and detach from the storage cavity 31 through the limiting unit 7. The bacterial test strip 4 and the rust prevention test box 5 will fall and detach from the buckle 62 due to their own weight. The dovetail block 61 will slide down in the dovetail groove 111, so that the bacterial test strip 4 and the rust prevention test box 5 slide to the top of the constant temperature cavity 21. The limiting rod 17 will be inserted into the slot 142 so that the lid 11 is locked and fixed on the box body 1. At this time, the worker can add metalworking fluid to the bacterial test strip 4 and the rust prevention test box 5.

[0055] After the metalworking fluid is fed, the worker will loosen the pull ring 123. The cover 11 will fall down and close the opening of the box body 1 due to its own weight. The bacterial test strip 4 and the rust prevention test box 5 will be embedded downward into the corresponding constant temperature chamber 21. The cover 62 will be fastened downward at the opening of the bacterial test strip 4 or the rust prevention test box 5 so that the constant temperature chamber 21 can keep the bacterial test strip 4 and the rust prevention test box 5 at a constant temperature.

[0056] After the metalworking fluid has been kept at a constant temperature, the worker presses down on the lid 11 with one hand and pulls the ring 123 located directly above the constant temperature chamber 21 with the other hand. This causes the end of the rotating plate 12 located directly above the constant temperature chamber 21 to flip upwards and contact the bottom of the lid 11. Then, the worker stops pressing down on the lid 11 and continues to pull the ring 123. The ring 123, through the pull rope 122 and the rotating plate 12, causes the lid 11 to rise and detach from the chamber 1. The limiting rod 17 will then re-engage in the slot 142, locking the lid 11 securely in place. 1. During the upward movement, the dovetail block 61 and the cover 62 will drive the bacterial test strip 4 and the rust prevention test box 5 to rise and detach from the constant temperature chamber 21. Due to their own gravity, the bacterial test strip 4 and the rust prevention test box 5 will fall and detach from the cover 62. The dovetail block 61 will slide down in the dovetail groove 111, so that the bacterial test strip 4 and the rust prevention test box 5 slide directly above the storage chamber 31. At this time, the worker can directly extract the metal processing fluid in the bacterial test strip 4 and the rust prevention test box 5 for testing, and it is also convenient for the worker to clean the metal processing fluid in the bacterial test strip 4 and the rust prevention test box 5.

[0057] After the metalworking fluid is tested and cleaned, the worker will pull the limit rod 17 away from the slot 142. At this time, the cover 11 will close downwards onto the box body 1 due to its own weight. The bacterial test strip 4 and the rust prevention test box 5 will be stored back in the corresponding storage cavity 31. The cover 62 will close again at the opening of the bacterial test strip 4 and the rust prevention test box 5, realizing the automatic reset of the bacterial test strip 4 and the rust prevention test box 5.

[0058] In summary, this application enables the synchronous opening and closing of all bacterial test strips 4 and rust prevention test boxes 5 by pulling the pull ring 123 and the limiting rod 17, and allows a specified number of bacterial test strips 4 and rust prevention test boxes 5 to be freely transferred between the storage chamber 31 and the constant temperature chamber 21 without requiring workers to repeat complex operating steps multiple times, thereby improving the detection efficiency of metalworking fluids.

[0059] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
