Description

Technical Field

[0001] This utility model relates to the field of laboratory scientific research, specifically a filter holder for fixing beakers. Background Technology

[0002] Filtration equipment is generally used to separate solids and liquids in mixtures. It is widely used in laboratories, industrial production and daily life. Traditional filtration devices can only hold one beaker at a time. When the filtrate needs to be dispensed into other containers, the beaker must be manually removed. Not only must the beaker be removed, but it must also be fixed in place. If the beaker is accidentally bumped during the experiment, its position will move or tip over, resulting in loss. Therefore, a filter holder that can fix the beaker needs to be designed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a filter holder that can fix a beaker in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filter holder for fixing beakers, comprising a base, a rotating shaft fixedly connected to the center of the top of the base, a turntable provided on the outer side of the rotating shaft, four sets of grooves opened on the top of the turntable, fixing components for fixing beakers provided inside the grooves, a fixing screw provided on the top of the base, a support plate fixed to the outer side of the fixing screw by two sets of bolts, a placement hole opened on the support plate, and a funnel placed inside the placement hole.

[0005] Preferably, the fixing component includes a spring, one side of which is fixedly connected to one side of the groove, and the other side of which is fixedly connected to a fixing plate.

[0006] Preferably, the spring is provided in two sets, and the two sets of springs are arranged opposite each other on the inner wall of the groove.

[0007] Preferably, both sets of bolts and fixing screws are threaded connections.

[0008] Preferably, the grooves are provided in four groups, evenly distributed in a ring on the top of the turntable.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the fixing plate is manually pressed backward to compress the spring, and then the beaker is placed in. The spring's rebound causes the fixing plate to abut against the beaker, stabilizing the beaker's position. Then, the same method is used to place the beakers in the remaining three grooves. After that, the bolts are loosened to adjust the position of the support plate, and then the funnel is placed in the placement hole. The required filter paper is placed in the funnel, and the raw material to be filtered is poured in. After the raw material is filtered, the turntable is rotated to move the second beaker under the funnel, and the raw material is poured in for filtration. When the four beakers are full of filtrate, the beakers are directly removed manually, reducing the number of manual beaker changes and the risk of beakers being knocked over, thereby reducing the loss of filtrate.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Example 1 Please refer to Figure 1-2 As shown, this utility model provides a filter holder for fixing beakers, including a base 1, a rotating shaft 2 fixedly connected to the center of the top of the base 1, a turntable 3 provided on the outside of the rotating shaft 2, four sets of grooves 4 opened on the top of the turntable 3, fixing components for fixing beakers are provided inside the grooves 4, a fixing screw 5 is provided on the top of the base 1, and a support plate 7 is fixed to the outside of the fixing screw 5 by two sets of bolts 6, a placement hole 8 is opened on the support plate 7, and a funnel 9 is placed inside the placement hole 8.

[0014] The turntable 3 can rotate around the axis 2. The fixing component can fix the beaker in the groove 4 to prevent the beaker from tipping over and causing material loss. The support plate 7 can move up and down along the fixing screw 5. The upper part of the fixing screw 5 is threaded and can be fixed by tightening two sets of bolts 6 in different directions. Different types of filter paper or filter screen can be placed inside the funnel 9 to filter the raw materials.

[0015] The fixing component includes a spring 10, one side of which is fixedly connected to one side of the groove 4, and the other side of which is fixedly connected to a fixing plate 11. There are two sets of springs 10, which are arranged opposite each other on the inner wall of the groove 4. Both sets of bolts 6 and fixing screws 5 are threaded connections. Filter paper is placed inside the funnel 9.

[0016] The process involves manually pressing the fixing plate 11 backward to compress the spring 10, then placing the beaker in the beaker. The spring 10 then rebounds, causing the fixing plate 11 to contact the beaker and stabilize its position. The position of the support plate 7 is adjusted by unscrewing the bolt 6. The funnel 9 is then placed into the placement hole 8, and the required filter paper is placed inside the funnel 9. Finally, the raw material to be filtered is poured in.

[0017] Working principle: By manually pressing the fixing plate 11 backward, the spring 10 is compressed, and then the beaker is placed in. The spring 10 rebounds, causing the fixing plate 11 to abut against the beaker, stabilizing the position of the beaker. Then, the same method is used to place the beakers in the remaining three grooves 4. After that, the bolt 6 is loosened to adjust the position of the support plate 7, and then the funnel 9 is placed in the placement hole 8. The required filter paper is placed in the funnel 9, and the raw material to be filtered is poured in. After the raw material is filtered, the turntable 3 is rotated to move the second beaker below the funnel 9, and the raw material is poured in for filtration. When the four beakers are full of filtrate, the beakers are removed manually.

[0018] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
