Description

Technical Field

[0001] The present application relates to the technical field of experimental equipment, and in particular to a multifunctional foldable integrated funnel rack. Background Art

[0002] In scientific experiments, when a large number of experimental samples are filtered, many funnel supports are required to support the funnels. At the same time, a large number of funnel racks and funnels need to be carried for use in long-distance experiments.

[0003] Chinese Patent No. CN206688737U discloses a funnel rack. When conducting an experimental sample filtering experiment, the funnel is placed in the funnel insertion hole on the funnel rack. However, the size of the funnel rack is relatively large, and it is not easy to store after use, occupying a large space and being inconvenient to carry for long-distance experiments. Utility Model Content

[0004] In order to improve the problems that the funnel rack has a relatively large size, is not easy to store after use, occupies a large space, and is inconvenient to carry for long-distance experiments, the present application provides a multifunctional foldable integrated funnel rack.

[0005] The multifunctional foldable integrated funnel rack provided by the present application adopts the following technical solutions:

[0006] A multifunctional foldable integrated funnel rack includes a funnel plate and multiple groups of support frames. The funnel plate and the multiple groups of support frames can be spliced into a funnel rack.

[0007] The funnel plate includes multiple unit plates. Each unit plate is provided with a funnel slot for inserting a funnel. Adjacent two unit plates are detachably connected through a splicing structure.

[0008] The support frame includes two support rods arranged crosswise. The two support rods are rotatably connected through a rotating shaft so that the two support rods can be folded collinearly. The two support rods are connected through a support component, and the support component is used to fix the two support rods in a cross-expanded state.

[0009] By adopting the above technical solutions, when the funnel rack is in use, multiple unit plates are spliced into a funnel plate through the splicing structure. The two support rods in each group of support frames are arranged crosswise, and then the two support rods are fixed through the support component. Then the support frame and the funnel plate are spliced into one for use. When the funnel rack is not in use, the support frame and the funnel plate are disassembled. Then the funnel plate is disassembled into multiple unit plates through the splicing structure, and the multiple unit plates are folded. Then the fixing of the two support rods is released through the support component, so that the two support rods rotate and fold around the rotating shaft, realizing the folding of the entire funnel rack, reducing the size of the funnel rack after use, and being convenient for carrying in long-distance experiments.

[0010] In a specific feasible implementation, the splicing structure includes a clamping groove and a clamping portion. The clamping groove is provided on one of the unit plates, and the clamping portion is provided on the corresponding unit plate. The clamping portion can be inserted into the clamping groove to connect two adjacent unit plates.

[0011] By adopting the above technical solution, when splicing two adjacent unit plates, the clamping portion on one unit plate is inserted into the clamping groove of the other unit plate, thereby completing the splicing of the two unit plates. The structure is simple and the installation is convenient.

[0012] In a specific feasible implementation, a plurality of elastic pieces are provided on the circumferential side wall of the funnel slot. The plurality of elastic pieces are uniformly arranged along the circumference of the funnel slot, and each elastic piece is inclined with respect to the axis of the funnel slot, so that the funnel inserted into the funnel slot can squeeze the elastic piece to deform towards the slot wall of the funnel slot.

[0013] By adopting the above technical solution, relying on the elastic deformation of the elastic piece, funnels of different models can be tightly pressed in the funnel slot, so as to adapt to the use of funnels of different models.

[0014] In a specific feasible implementation, the support assembly includes a fixing rod and a fixing member. One end of the fixing rod is hinged to one of the support rods, and the other end is fixedly connected to the other support rod through the fixing member. The fixing rod can be folded collinearly with the support rod.

[0015] By adopting the above technical solution, when assembling the support frame, when the two support rods are unfolded crosswise, the fixing rod is rotated to the bottom of the other support rod, and then the fixing rod and the bottom of the support rod are fixed through the fixing member, so that the two support rods are kept in a stable open state, ensuring that the support frame can stably support the funnel plate.

[0016] In a specific feasible implementation, the fixing member includes a fixing bolt, and the fixing bolt can be inserted through the fixing rod and the support rod along the circumferential direction of the rotating shaft.

[0017] By adopting the above technical solution, when the fixing rod rotates to the bottom of the other support rod, the fixing bolt is passed through the fixing rod and the support rod to complete the fixed connection between the support rod and the fixing rod, so that the two support frames form a triangular structure. Using the triangular structure, the stability is strong; it can be folded, stored, occupies a small space, and is convenient to carry.

[0018] In a specific feasible implementation, a fixing nut is threadedly sleeved on the fixing bolt.

[0019] By adopting the above technical solution, when the fixing bolt passes through the fixing rod and the support rod, the fixing nut is screwed onto the fixing bolt, thereby improving the stability of the fixing of the fixing bolt to the fixing rod and the support rod.

[0020] In a specific feasible implementation, each of the support rods is provided with a telescopic groove, and a telescopic block for sliding in the telescopic groove is arranged on the support rod. A tightening bolt is threadedly inserted into the telescopic block, and the tightening bolt can be tightened against the groove wall of the telescopic groove so as to fix the telescopic block.

[0021] By adopting the above technical solution, the telescopic block is extended out of the telescopic groove by a certain length, and then the tightening bolt is rotated to be tightened and fixed against the groove wall of the telescopic groove to complete the fixing of the telescopic block. By extending the telescopic block out of the telescopic groove, the support height of the support frame can be adjusted according to the height requirements of different experimental scenarios.

[0022] In a specific feasible implementation, an L-shaped placing plate is hinged to each of the telescopic blocks. The L-shaped placing plate can rotate around the hinge axis in the vertical plane so as to adjust the inclination angle of the L-shaped placing plate. The two L-shaped placing plates are arranged oppositely so that the funnel plate can be placed on the two L-shaped placing plates. A limiting member for fixing the L-shaped placing plate is arranged on the telescopic block.

[0023] By adopting the above technical solution, as the extending lengths of the two telescopic blocks are adjusted, the inclination angle of the funnel plate can be adjusted. At this time, the L-shaped placing plate rotates around the hinge axis to adapt to the change of the inclination angle of the funnel plate. Then, the L-shaped placing plate is fixed by the limiting member, so that the L-shaped placing plate can stably support the funnel plate. The support frame is not only adjustable in height but also adjustable in slope, and can be adjusted to different angles according to experimental requirements, applied to different scenarios, and used with various types of funnels.

[0024] In a specific feasible implementation, the limiting member includes a worm gear and a worm that mesh with each other. The worm is rotatably connected to the telescopic block, and the worm gear is coaxially and fixedly arranged on the hinge axis.

[0025] By adopting the above technical solution, when adjusting the inclination angle of the L-shaped placing plate, the worm is rotated to drive the worm gear to rotate, the worm gear drives the hinge axis to rotate, and then drives the inclination angle of the L-shaped placing plate to be adjusted. After the adjustment is completed, due to the self-locking characteristics of the worm gear and the worm, the L-shaped placing plate can be fixed, thereby improving the convenience of adjusting and fixing the L-shaped placing plate.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. After the funnel rack is no longer in use, disassemble the support frame and the funnel plate, then disassemble the funnel plate into multiple unit plates through the splicing structure, fold up the multiple unit plates, and then release the fixation of the two support rods through the support assembly, so that the two support rods rotate and fold around the rotation axis, realizing the folding of the entire funnel rack, reducing the size of the funnel rack after use, and facilitating the carrying for long-distance experiments;

[0028] 2. The support frame is in a triangular structure. Utilizing the triangular structure, it has strong stability; it is foldable, storable, occupies little space, and is easy to carry;

[0029] 3. The support frame is not only adjustable in height but also in slope, and can be adjusted to different angles according to experimental needs, applied to different scenarios, and used with various types of funnels. Brief Description of the Drawings

Detailed Embodiment

[0035] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings.

[0036] The embodiment of the present application discloses a multifunctional foldable integrated funnel rack.

[0037] Refer to Figure 1 、 Figure 2, a multifunctional foldable integrated funnel rack includes a funnel plate 1 and multiple groups of support frames 2. The funnel plate 1 and the multiple groups of support frames 2 can be spliced into a funnel rack. In this embodiment, there are two groups of support frames 2. Both the support frames 2 and the funnel plate 1 are made of plastic materials, which are light in weight, not easily deformed, strong in load-bearing, and good in stability. The funnel plate 1 includes multiple unit plates 11. In this embodiment, the multiple unit plates 11 are arranged in a single column. Each unit plate 11 is provided with a funnel slot 12 for inserting a funnel. Adjacent two unit plates 11 are detachably connected through a splicing structure 13. Each group of support frames 2 in this embodiment includes two support rods 21 arranged in a cross shape. The centers of the two support rods 21 are rotationally connected through a rotating shaft 22, so that the two support rods 21 can be folded collinearly. The bottoms of the two support rods 21 are connected through a support assembly 3. The support assembly 3 is used to fix the two support rods 21 in a cross-open state.

[0038] When using the funnel rack, splice multiple unit plates 11 into the funnel plate 1 through the splicing structure 13. Set the two support rods 21 in each group of support frames 2 in a cross shape, and then fix the two support rods 21 through the support assembly 3. Then splice the support frames 2 and the funnel plate 1 into one for use; when the funnel rack is not in use, disassemble the support frames 2 and the funnel plate 1, then disassemble the funnel plate 1 into multiple unit plates 11 through the splicing structure 13, and fold up the multiple unit plates 11. Then release the fixation of the two support rods 21 through the support assembly 3, so that the two support rods 21 rotate and fold around the rotating shaft 22, realizing the folding of the entire funnel rack, reducing the size of the funnel rack after use, and facilitating the carrying for long-distance experiments.

[0039] Refer to Figure 2 , the splicing structure 13 in this embodiment includes a clamping groove 131 and a clamping part 132. The clamping groove 131 is arranged on the side wall of one unit plate 11. The clamping groove 131 in this embodiment is a dovetail groove with an opening facing another unit plate 11. The clamping part 132 is fixedly arranged on the side wall of another unit plate 11 opposite to the clamping groove 131. A tight fit is adopted between the clamping part 132 and the clamping groove 131. When installing adjacent two unit plates 11, slide the clamping part 132 on one unit plate 11 into the clamping groove 131 from one side to complete the splicing between the two unit plates 11. Repeat the above connection method to splice multiple unit plates 11 into the funnel plate 1. When disassembling the funnel plate 1, pull out the clamping part 132 from the clamping groove 131 to complete the disassembly of the funnel plate 1. The disassembled unit plates 11 can be stacked together, thereby reducing the size of the funnel plate 1 and facilitating the transportation of the funnel plate 1.

[0040] Refer to Figure 2, when the funnel plate 1 is in use, in order to meet the requirements of different experiments, funnels of different specifications need to be placed in the funnel slots 12. In addition, test tubes also need to be placed in the funnel slots 12. For this purpose, a plurality of elastic pieces 14 are provided on the side walls of each funnel slot 12. The plurality of elastic pieces 14 are uniformly arranged along the circumferential direction of the side wall of the funnel slot 12. The top of each elastic piece 14 is fixedly connected to the side wall of the funnel slot 12, and the bottom of each elastic piece 14 approaches the middle of the funnel slot 12, so that the elastic piece 14 is inclined with respect to the axis of the funnel slot 12. When the funnel or the test tube is inserted into the funnel slot 12 from top to bottom, the elastic piece 14 deforms and abuts against the funnel or the test tube, so that funnels or test tubes of different models can be abutted tightly in the funnel slot 12, thus adapting to the use of funnels or test tubes of different models.

[0041] Refer to Figure 3 , Figure 4 , the support assembly 3 in this embodiment includes a fixed rod 31 and a fixing member 32. The fixed rod 31 is arranged at the bottom of the support rod 21. The support rod 21 rotatably connected to the fixed rod 31 is located between another support rod 21 and the fixed rod 31. One end of the fixed rod 31 is rotatably connected to a support rod 21 through a rotating shaft, and the other end is fixedly connected to another support rod 21 through the fixing member 32. The fixing member 32 in this embodiment includes a fixing bolt 321. Through holes 322 are formed in both the other support rod 21 and the fixed rod 31. When the two through holes 322 are aligned, the fixing bolt 321 is sequentially passed through the two through holes 322, thereby realizing the fixation between the fixed rod 31 and the support rod 21. At this time, a triangular structure is formed between the two support rods 21 and the fixed rod 31. By using the triangular structure, the stability is strong; it can be folded, stored, occupies a small space, and is convenient to carry. In order to improve the stability of the fixation of the fixing bolt 321 between the fixed rod 31 and the support rod 21, a fixing nut 323 is sleeved on the fixing bolt 321. When the fixing bolt 321 passes through the two through holes 322, the fixing nut 323 is screwed onto the fixing bolt 321, thereby effectively preventing the fixing bolt 321 from falling off and improving the stability of the fixation of the fixing bolt 321 between the fixed rod 31 and the support rod 21.

[0042] Refer to Figure 3 , Figure 4, in order to meet the requirements of different experiments for the height or inclination angle of the funnel plate 1, a telescopic groove 211 is provided at the top of each support rod 21. The telescopic groove 211 is arranged along the length direction of the support rod 21. Each support rod 21 is provided with a telescopic block 212 that slides in the telescopic groove 211. A tightening bolt 213 is threadedly inserted into each telescopic block 212. To facilitate the rotation of the tightening bolt 213, a sliding groove 214 is provided on one side of the support rod 21 in the rotation direction. The tightening bolt 213 slides in the sliding groove 214. The telescopic block 212 is extended out of the telescopic groove 211, and then the tightening bolt 213 is rotated to be tightened and fixed on the side wall of the telescopic groove 211, realizing the fixation between the telescopic block 212 and the telescopic groove 211. By the different extended heights of the two telescopic blocks 212, the inclination angle of the funnel plate 1 is adjusted.

[0043] Refer to Figure 3 , Figure 4 , a set of hinge supports 41 are fixedly provided at the top of each telescopic block 212. A hinge shaft 42 is rotatably connected to the set of hinge supports 41. The axis of the hinge shaft 42 is parallel to the axis of the rotating shaft 22. An L-shaped placing plate 43 is fixedly provided on the hinge shaft 42. The hinge shaft 42 is located at the corner of the L-shaped placing plate 43. The L-shaped placing plates 43 on the two telescopic blocks 212 of the same group are arranged oppositely. The funnel plate 1 is placed on the bottom straight edge sections of the two L-shaped placing plates 43. A mounting bolt 44 is threadedly inserted through the other straight edge section. Rotating the mounting bolt 44 can tightly fix the funnel plate 1 on the bottom straight edge section of the L-shaped placing plate 43, thereby improving the connection stability between the funnel plate 1 and the L-shaped placing plate 43.

[0044] Refer to Figure 4 , a limiting member 45 is provided at the top of the telescopic block 212. In this embodiment, the limiting member 45 includes a worm gear 451 and a worm 452 that mesh with each other. The worm gear 451 is coaxially and fixedly provided on the hinge shaft 42. The worm 452 is inserted into the telescopic block 212 along the length direction of the telescopic block 212 and is rotatably connected to the telescopic block 212. When adjusting the inclination angle of the L-shaped placing plate 43, the worm 452 is rotated to drive the worm gear 451 to rotate. The worm gear 451 drives the hinge shaft 42 to rotate, and then drives the inclination angle of the L-shaped placing plate 43 to be adjusted. After the adjustment is completed, due to the self-locking characteristics of the worm gear 451 and the worm 452, the L-shaped placing plate 43 can be fixed, thereby improving the convenience of adjusting and fixing the L-shaped placing plate 43.

[0045] The implementation principle of a multifunctional foldable integrated funnel rack in an embodiment of this application is as follows: When the funnel rack is in use, multiple unit plates 11 are spliced into a funnel plate 1 through the cooperation of the clamping portion 132 and the clamping groove 131. The two support rods 21 in each group of support frames 2 are arranged crosswise. Then, rotate the fixing rod 31 so that the two through holes 322 are aligned. Then, pass the fixing bolt 321 through the two through holes 322, and then screw the fixing nut 323 onto the fixing bolt 321 to fix the two support rods 21. At the same time, adjust the length of the telescopic block 212 extending out and the inclination angle of the L-shaped placing plate 43. Then, place the funnel plate 1 on the L-shaped placing plate 43, and rotate the mounting bolt 44 to tightly press and fix the funnel plate 1 on the L-shaped placing plate 43.

[0046] After the funnel rack is used up, disassemble the support frame 2 and the funnel plate 1. Then, pull out the clamping portion 132 from the clamping groove 131 to disassemble the funnel plate 1 into multiple unit plates 11, and fold up the multiple unit plates 11. Then, disassemble the fixing nut 323, pull out the fixing bolt 321 from the through hole 322 to release the fixation of the two support rods 21. The two support rods 21 rotate and fold around the rotating shaft 22, and the rotating fixing rod 31 folds with the support rod 21. By folding the funnel plate 1 and the support frame 2, the folding of the entire funnel rack is realized, reducing the size of the funnel rack after use and facilitating the carrying for long-distance experiments.

[0047] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
