[0001] This utility model belongs to the field of experimental auxiliary equipment, specifically a multi-aperture adjustable funnel holder. Background Technology

[0002] In experiments in the fields of chemistry, pharmaceuticals, and food, researchers use funnels to filter and process solutions. The funnel is placed on a funnel stand, and a container is placed below the funnel to collect the solution.

[0003] In the same set of experiments, the experimenters will use multiple funnels, and the apertures of these funnels will vary. However, since the aperture size of the funnel holder is fixed, it is necessary to find a funnel that matches its aperture, which will delay the smooth progress of the overall experiment. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a multi-aperture adjustable funnel frame to solve the issues raised in the above technical background.

[0005] A multi-aperture adjustable funnel frame includes a support frame assembly, wherein a plurality of funnel frame assemblies are fixedly installed on the center of the top surface of the support frame assembly, and a lifting assembly matching the funnel frame assemblies is installed on the bottom surface of the support frame assembly.

[0006] The funnel frame assembly includes a T-shaped base plate with a through hole in the middle. Trapezoidal frames are fixedly installed on the top surfaces of the T-shaped base plate on both sides of the through hole. A second sliding groove parallel to the inclined plane is opened in the middle of each of the two trapezoidal frames. A rhomboid slider is slidably installed in the inner cavity of the second sliding groove. A connecting seat is fixedly installed on the wall surface of each of the two rhomboid sliders that are close to each other. An arc-shaped clamping rod is fixedly installed on the wall surface of the connecting seat.

[0007] The funnel frame assembly also includes a T-shaped slide block fixedly installed in the middle of the other side wall of the rhomboid slider and a first internal thread block fixedly installed in the middle of the top surface of the trapezoidal frame. A threaded rod is threadedly installed in the middle of the first internal thread block, and a T-shaped slider is rotatably installed on the bottom surface of the threaded rod. The T-shaped slider is slidably disposed in the inner cavity of the T-shaped slide block.

[0008] Preferably, the support frame assembly includes two symmetrically parallel side plates, a platform is fixedly installed between the top surfaces of the two side plates, a container platform is slidably installed in the middle of the two side plates, and anti-slip feet are symmetrically fixedly installed on the bottom surfaces of the two side plates.

[0009] Preferably, the inner wall of the platform is provided with a first sliding groove for sliding with a T-shaped base plate, and the T-shaped base plate is provided with placement openings at both ends of the first sliding groove for placing the T-shaped base plate.

[0010] Preferably, the lifting assembly includes a rotating block fixedly installed between the middle of the bottom surfaces of the two side plates and a hinge seat fixedly installed in the middle of the bottom surface of the container platform. A bidirectional lead screw is rotatably installed in the middle of the rotating block. The two ends of the bidirectional lead screw are symmetrically threaded with second internal thread blocks. A connecting rod is hingedly installed on the top surface of each of the two second internal thread blocks. The other end of each of the two connecting rods is hingedly installed to the hinge seat.

[0011] Preferably, one end of the bidirectional lead screw is fitted with a rotating handle that extends through the outer wall of the bidirectional lead screw.

[0012] Preferably, an arc-shaped strip is adhered to the outer wall surface of the arc-shaped clamping rod, and the arc-shaped strip is made of flexible rubber.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model rotates two sets of threaded rods, causing their lower ends to move towards the middle of the trapezoidal frame. As the lower ends of the threaded rods descend, the T-shaped sliding block and the rhomboid slider also descend. At this time, the T-shaped slider on the bottom surface of the threaded rod slides in the T-shaped sliding block. The descending state of the rhomboid slider is that it slides in the second sliding groove along the direction of the downward opening of the second sliding groove. The connecting seat and the arc-shaped clamping rod at the front end of the rhomboid slider slide accordingly. The two arc-shaped clamping rods approach each other horizontally to clamp the funnel. Then, by adjusting the height of the two arc-shaped clamping rods on the trapezoidal frame, funnels with different apertures can be clamped.

[0015] 2. This utility model allows the T-shaped base plate to be placed into the first sliding groove through the placement port, thereby enabling the simultaneous use and quick removal of multiple funnel frame assemblies. Furthermore, the spacing between multiple funnel frame assemblies can be adjusted by sliding the entire funnel frame assembly. By adjusting the height of the container platform, the liquid outlet at the lower end of the funnel can be better positioned in the middle of the container, preventing the liquid outlet at the lower end of the funnel from being too high from the top surface of the container, which would cause liquid to splash out of the container.

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] Example 1:

[0028] Reference Appendix Figure 1 To be continued Figure 6 As shown, a multi-aperture adjustable funnel frame includes a support frame assembly 1, a plurality of funnel frame assemblies 2 are fixedly installed on the middle of the top surface of the support frame assembly 1, and a lifting assembly 3 matching the funnel frame assemblies 2 is installed on the bottom surface of the support frame assembly 1.

[0029] The funnel frame assembly 2 includes a T-shaped base plate 201, with a through hole 202 in the middle of the T-shaped base plate 201. Trapezoidal frames 203 are fixedly installed on the top surfaces of the T-shaped base plate 201 on both sides of the through hole 202. A second sliding groove 204 parallel to the inclined plane is opened in the middle of the two trapezoidal frames 203. A rhomboid slider 205 is slidably installed in the inner cavity of the second sliding groove 204. A connecting seat 206 is fixedly installed on the wall surface of the two rhomboid sliders 205 that are close to each other. An arc-shaped clamping rod 207 is fixedly installed on the wall surface of the connecting seat 206.

[0030] The funnel frame assembly 2 also includes a T-shaped slide block 209 fixedly installed in the middle of the other side wall of the rhomboid slider 205 and a first internal thread block 210 fixedly installed in the middle of the top surface of the trapezoidal frame 203. A threaded rod 211 is threadedly installed in the middle of the first internal thread block 210, and a T-shaped slider 212 is rotatably installed on the bottom surface of the threaded rod 211. The T-shaped slider 212 is slidably disposed in the inner cavity of the T-shaped slide block 209.

[0031] As can be seen from the above, by rotating the two sets of threaded rods 211, their lower ends move towards the middle of the trapezoidal frame 203. At the same time as the lower ends of the threaded rods 211 descend, the T-shaped slide block 209 and the rhomboid slider 205 also descend. At this time, the T-shaped slider 212 on the bottom surface of the threaded rods 211 slides in the T-shaped slide block 209. The descending state of the rhomboid slider 205 is that it slides in the second slide 204 along the direction of the downward opening of the second slide 204. The connecting seat 206 and the arc-shaped clamping rod 207 at the front end of the rhomboid slider 205 slide accordingly. The two arc-shaped clamping rods 207 approach each other horizontally to clamp the funnel. Then, by adjusting the height of the two arc-shaped clamping rods 207 on the trapezoidal frame 203, the funnels with different apertures can be clamped.

[0032] Example 2:

[0033] Reference Appendix Figure 1 To be continued Figure 6 As shown, the support frame assembly 1 includes two symmetrically parallel side plates 101, a platform 102 is fixedly installed between the top surfaces of the two side plates 101, a container platform 103 is slidably installed in the middle of the two side plates 101, and anti-slip feet 104 are symmetrically fixedly installed on the bottom surfaces of the two side plates 101.

[0034] The inner wall of the platform 102 is provided with a first groove 105 for sliding the T-shaped base plate 201. The T-shaped base plate 201 is provided with placement openings 106 at both ends of the first groove 105 for placing the T-shaped base plate 201.

[0035] As can be seen from the above, by placing the T-shaped base plate 201 into the first slide groove 105 through the placement port 106, multiple funnel rack assemblies 2 can be used simultaneously and quickly removed. The spacing between multiple funnel rack assemblies 2 can be adjusted by sliding the funnel rack assembly 2 as a whole. By adjusting the height of the container platform 103, the liquid outlet at the lower end of the funnel can be better positioned in the middle of the container, avoiding the liquid outlet at the lower end of the funnel being too high from the top surface of the container, which would cause the liquid to splash out of the container.

[0036] Example 3:

[0037] Reference Appendix Figure 1 To be continued Figure 6As shown, the lifting assembly 3 includes a rotating block 301 fixedly installed between the middle of the bottom surfaces of the two side plates 101 and a hinge seat 305 fixedly installed in the middle of the bottom surface of the container platform 103. A bidirectional screw 302 is rotatably installed in the middle of the rotating block 301. The two ends of the bidirectional screw 302 are symmetrically threaded with second internal thread blocks 303. The top surfaces of the two second internal thread blocks 303 are hingedly installed with connecting rods 304. The other ends of the two connecting rods 304 are hingedly installed with the hinge seat 305.

[0038] A rotating handle 306 is installed at one end of the double-acting lead screw 302, extending through the outer wall of the double-acting lead screw 302.

[0039] As can be seen from the above, by rotating the handle 306, the bidirectional lead screw 302 is driven to rotate, which in turn drives the two second internal thread blocks 303 to move closer to each other in the rotating slot block 301. This causes the angle between the two connecting rods 304 hinged on the hinge seat 305 to gradually decrease. At this time, the hinge seat 305 rotates vertically upward, which pushes the container platform 103 to slide upward. In addition, during the test, the distance between the container on the container platform 103 and the liquid outlet at the lower end of the funnel can be adjusted to improve the adaptability of the height adjustment of the container platform 103.

[0040] An arc-shaped strip 208 is bonded to the outer wall of the arc-shaped clamping rod 207. The arc-shaped strip 208 is made of flexible rubber.

[0041] As can be seen from the above, when the two arc-shaped clamping rods 207 clamp the outer wall of the funnel, the arc-shaped strip 208 can better fit the outer wall of the funnel, improve the stability of clamping, and achieve a better clamping effect.

[0042] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
