[0008] The above search results show that the above technical solutions do not affect the novelty of this utility model; and the combination of the above prior art does not destroy the inventiveness of this utility model. Utility Model Content

[0009] This invention aims to overcome the shortcomings of the existing technology by providing a funnel frame with a lifting and rotating structure.

[0010] The present invention adopts the following technical solution to solve the technical problem: a funnel frame with a lifting and rotating structure, wherein a limiting hole for limiting the placement of the funnel is provided on the top plate, and a base is provided below the top plate, wherein a container for receiving liquid in the funnel is placed on the base and located directly below the funnel, and a lifting structure is provided;

[0011] The lifting structure includes a fixed cylinder, a lifting cylinder, and a locking structure;

[0012] The fixed cylinder and the lifting cylinder are slidably fitted together, forming a sliding pair that supports the lifting cylinder in driving the top plate, which is fixed to the top of the lifting cylinder, to slide up or down. A locking structure is also provided between the fixed cylinder and the lifting cylinder to limit the relative sliding between the fixed cylinder and the lifting cylinder.

[0013] Furthermore, the locking structure includes a row of lifting cylinder openings on the side wall of the lifting cylinder, corresponding fixing cylinder openings on the side wall of the fixing cylinder, and a locking bolt;

[0014] The locking bolt passes through the opening of the fixed cylinder and any of the openings of the lifting cylinder, thereby restricting the relative sliding between the fixed cylinder and the lifting cylinder.

[0015] Furthermore, the side wall of the lifting cylinder protrudes towards the fixed cylinder to form a sliding rod, and the side wall of the fixed cylinder is correspondingly recessed to form a sliding groove. The sliding rod is slidably engaged and locked in the sliding groove; the row of openings in the lifting cylinder is located on the sliding rod.

[0016] Furthermore, a row of lifting cylinder openings and a fixed cylinder opening are grouped together, and the lifting structure is provided with at least two groups of lifting cylinder openings and fixed cylinder openings evenly distributed along the circumference.

[0017] Furthermore, the base has a top-opening groove structure, and a drain pipe is opened at the bottom of its side wall.

[0018] A drain valve is installed on the drain pipe as needed.

[0019] When using the funnel holder described above, during the process of transferring liquid from the funnel to the container, a small amount of splashed or leaked liquid can be collected in the trough-shaped structure of the base and discharged for centralized treatment via the drain pipe.

[0020] Furthermore, the base has an annular groove structure with an open top, and the bottom of the fixed cylinder is inserted into the inner circle of the annular groove structure; a sliding pair supporting the upward or downward movement of the fixed cylinder and a rotating pair supporting the rotation of the fixed cylinder around its own axis are formed between the base and the fixed cylinder.

[0021] Furthermore, the top plate is provided with various limiting holes evenly distributed along the circumference, and the base is provided with a limiting structure below each limiting hole for limiting the container.

[0022] Furthermore, the limiting structure is a limiting groove or a platform with an upper boss-shaped structure, or the limiting structure is a clamping structure including a pair of clamping springs and a pair of clamping plates; the front ends of the pair of clamping springs are respectively installed and connected to the inner side of the outer wall of the annular groove structure and the outer side of the inner wall, and the rear ends are respectively installed and connected to the pair of clamping plates. The elastic force of the pair of clamping springs tends to make the pair of clamping plates move towards each other and move closer together, so as to clamp and limit the container placed between the pair of clamping plates.

[0023] Furthermore, it also includes washers that correspond one-to-one with the limiting holes;

[0024] The washer is located above the limiting hole and is fixed to the top plate.

[0025] Furthermore, the washer is a ring-shaped washer made of rubber, and the inner diameter of the ring is the same as the inner diameter of the limiting hole.

[0026] When using the above-mentioned funnel holder, the neck of the funnel passes through the washer and the limiting hole, and the shoulder is supported on the top of the washer; relying on the cushioning of the washer and the large friction provided by the washer, the funnel can be stably supported and limited by the washer.

[0027] This utility model provides a funnel frame with a lifting and rotating structure, which has the following beneficial effects:

[0028] 1. This utility model provides a lifting structure between the mounting base and the top plate to adjust the distance between the top plate and the mounting base, so as to adapt to the placement needs of containers of different heights, and further improve the adaptability and application range of the funnel frame.

[0029] 2. The mounting base of this utility model is designed with an annular groove structure, which can collect the liquid splashed or leaked during the liquid transfer process and discharge it through the drain pipe, which helps to maintain the cleanliness of the working environment and eliminates the safety hazards of some harmful liquid splashes.

[0030] 3. The lifting structure of this utility model can drive the top plate set on its top to rotate relative to the base, so that the operator can rotate and adjust the relative position of the funnel and the container, as well as the relative position of the funnel and the operator as needed, further improving the ease of use of the funnel frame.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Example 1

[0037] A funnel frame with a lifting and rotating structure, such as Figures 1-2 As shown, its structural relationship is as follows: it includes a top plate 1, a lifting structure 3 and a base 2 arranged sequentially from top to bottom.

[0038] The top plate 1 has circumferentially distributed limiting holes 11 for limiting and placing the funnel. A rubber ring-shaped washer 12 is fixed above each limiting hole 11, and the inner diameter of the washer 12 is the same as that of the limiting hole 11. When using the above-mentioned funnel frame, the neck of the funnel passes through the washer 12 and the limiting hole 11, and the shoulder is supported on the top of the washer 12. Relying on the cushioning of the washer 12 and the large friction provided by the washer 12, the funnel can be stably supported and limited by the washer 12.

[0039] The lifting structure 3 includes a fixed cylinder 31, a lifting cylinder 32, and a locking structure. The top plate 1 is fixed to the top of the lifting cylinder 32, which is fitted inside the fixed cylinder 31. Four protruding rod-shaped sliding rods 322 are evenly distributed circumferentially on the outer wall of the lifting cylinder 32. Four concave sliding grooves 312 are correspondingly formed on the inner wall of the fixed cylinder 31. The four sliding rods 322 are slidably fitted into the four sliding grooves 312, allowing the lifting cylinder 32 to slide upwards or downwards relative to the fixed cylinder 31. Five lifting cylinder openings 321 are arranged in a row on each sliding rod 322, and one fixed cylinder opening 311 is correspondingly formed on the side wall of the fixed cylinder 31 for each sliding rod 322. At each sliding rod 322, a locking bolt 33 passes through any lifting cylinder opening 321 and the corresponding fixed cylinder opening 311, restricting the relative sliding between the fixed cylinder 31 and the lifting cylinder 32.

[0040] The base 2 has an annular groove structure with an open top, and a drain pipe 21 is opened at the bottom of its side wall. A drain valve is installed on the drain pipe 21 as needed. When using the funnel frame, during the process of transferring liquid from the funnel to the container, a small amount of splashed or leaked liquid can be collected in the groove structure of the base 2 and discharged through the drain pipe 21 for centralized treatment. The bottom of the fixed cylinder 31 is inserted into the inner circle of the annular groove structure. A sliding pair supporting the upward or downward movement of the fixed cylinder 31 and a rotating pair supporting the rotation of the fixed cylinder 31 around its own axis are formed between the base 2 and the fixed cylinder 31. Within the groove-shaped structure of the base 2, a limiting structure is provided directly below the rotation path of each limiting hole 11. The type and number of limiting structures can be selected according to actual needs. They can be limiting grooves to facilitate the placement of containers such as beakers and flasks, or a platform 24 with an upwardly convex, pedestal-shaped structure to accommodate the liquid transfer needs of two containers with large height differences without adjusting the lifting structure 3. Alternatively, they can include a clamping structure consisting of a pair of clamping springs 22 and a pair of clamping plates 23. The front ends of the pair of clamping springs 22 are respectively installed and connected to the inner side of the outer wall of the annular groove-shaped structure and the outer side of the inner wall, and the rear ends are respectively installed and connected to a pair of clamping plates 23. The elastic force of the pair of clamping springs 22 tends to cause the pair of clamping plates 23 to move towards each other and close together to clamp and limit the container placed between the pair of clamping plates 23. This type of clamping structure is suitable for limiting test tube containers.

[0041] When using the above-mentioned funnel holder to transfer liquid into a container through a funnel, the following process is included:

[0042] The first step is to adjust the lifting structure 3 according to the height of the container so that the distance between the top plate 1 and the base 2 meets the needs of container placement. The adjustment process of the lifting structure 3 is as follows: remove each locking bolt 33, slide the lifting cylinder 32 relative to the fixed cylinder 31 to a suitable position, and then reinstall each locking bolt 33 to limit the relative sliding between the fixed cylinder 31 and the lifting cylinder 32.

[0043] When there are multiple containers to be pipetted, the height of each container should be taken into account.

[0044] The second step is to insert the bottom end of the fixing cylinder 31 into the inner circle of the annular groove structure of the base 2, and rotate the fixing cylinder 31 to adjust the position of the limiting hole 11 so that the limiting hole 11 is exactly above the limiting structure.

[0045] The third step is to securely place the container in the groove-shaped structure of the base 2 using the limiting structure.

[0046] Fourth step: Pass the neck of the funnel through the washer 12 and the limiting hole 11 to secure the shoulder of the funnel to the top of the washer 12, and then transfer the liquid into the container through the funnel.

[0047] During use, the operator can rotate the fixed cylinder 31 and the top plate 1 fixed to the top of the fixed cylinder 31 as needed to further improve the ease of use of the funnel frame; if multiple funnels are installed at multiple limiting holes 11, the funnel to be operated can be rotated to be closer to the operator for easy operation; or if it is necessary to transfer liquid to different containers through the same funnel, the funnel can be rotated to the top of each container in sequence for liquid transfer operation.
