Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a portable water centrifuge. Background Art

[0002] In order to obtain the quality of the ecological environment, it is necessary to monitor the quality of the water environment. The total phosphorus test in water is an important indicator of water quality testing. When testing the total phosphorus in water, it is necessary to collect water samples first and then complete the turbidity side view. The water samples need to be rationally settled during the test, so a centrifuge is needed. In order to facilitate outdoor water sample analysis, there are portable centrifuges on the market.

[0003] For example, Chinese utility model patent application number 2022231297349 discloses a portable centrifuge, which can be convenient for outdoor field operations. It includes a box body, a cover body and a small centrifuge arranged in the box body. In order to facilitate portability, two universal wheels are provided on the bottom surface of the box body, and two supporting feet are also provided. A telescopic pull rod is provided on the side of the box body close to the two universal wheels. When moving the portable centrifuge, the telescopic pull rod can be pulled out, and the upper end of the telescopic pull rod is held to tilt the box body, and the two universal wheels touch the ground, so that the box body can be pulled to move, which is convenient for carrying. When in use, the two universal wheels and the two supporting feet can be touched to the ground at the same time to support the box body. However, in actual use, it also has the following defects:

[0004] When the box body is moved, it is necessary to tilt the box body, and the centrifuge arranged inside includes a centrifugal seat, which is provided with a placement hole, and a centrifugal container is placed in the placement hole. At present, the centrifugal container is directly inserted into the placement hole. When the box body is tilted and moved, the centrifugal container may move out of the placement hole. The centrifugal container is generally made of stainless steel. When moving, it will hit the cover body and the centrifugal seat to generate noise. Especially when the road is bumpy, the noise is particularly obvious. The current solution is to separate and remove the centrifugal container from the centrifugal seat, place the centrifugal box body separately, and then temporarily install it when in use. This is inconvenient to use and requires an additional location for placing the centrifugal container. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0025] Please refer to Figure 1-6 To achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a portable water quality centrifuge, comprising a box body 1, a centrifuge body and a cover body arranged in the box body 1, the centrifuge body comprising a centrifugal seat 2, a plurality of sockets 22 arranged around the axis of the centrifugal seat 2, each socket being plugged into and fitted with a centrifugal container 3, the centrifugal container comprising a flange 31 abutting and limiting against the end of the socket, a limiting component being provided between the flange and the socket 22.

[0026] Specifically, as a specific embodiment, the portable centrifuge provided by the present application includes a box body 1, the box body includes a cover body 12 connected by a hinge 14, a baffle 11 is provided at the mouth of the box body, and a through hole is provided on the baffle to expose the centrifugal seat 2. The centrifuge is arranged in the box body and drives the centrifugal seat 2 to rotate around the axis when working. The centrifugal seat is an inverted conical decoupling strand, and a plurality of sockets 22 are evenly spaced on the side wall. The centrifugal container 3 is a columnar structure and can be inserted into the socket 22. The present application provides a flange 31 at the end of the centrifugal container 3. When the centrifugal container is inserted into the socket, the flange can abut and limit the end of the socket 22, and a limiting component is provided between the flange and the socket 22. The centrifugal container is axially limited by the limiting component. The flange and the limiting component cooperate to limit the centrifugal container 3 in two axial directions, thereby avoiding axial movement of the centrifugal container 3 when the box body is moved, and reducing the noise generated by the axial movement.

[0027] Furthermore, as another embodiment, four universal wheels 17 are provided at the four corners of the bottom surface of the box body, so that the four universal wheels can evenly contact the bottom surface when the box body is moved, so that the box body can be moved without tilting. The non-tilting of the box body can further reduce the probability of axial movement of the centrifuge container.

[0028] Further, as a specific implementation method, refer to Figure 4 A supporting surface 16 is provided in the box body, and the supporting surface is detachably fixedly connected to the side wall of the box body. Through holes are provided at the four corners of the baffle, and screws 13 are passed through the through holes. The screws pass through the lower end of the baffle and are sleeved with a support sleeve 15. Four threaded holes corresponding to the four screws are provided on the supporting surface. The lower end of the screw 13 is threadedly connected to the threaded hole on the supporting surface 16, and the two ends of the support sleeve 15 respectively abut the supporting surface 16 and the baffle 11 to provide supporting force for the baffle 11.

[0029] Further, as a specific implementation method, refer to Figure 4-Figure 6 The specific structure of the limiting component is as follows: the limiting component includes a first permanent magnet 32 and a second permanent magnet 33 respectively provided at the flange 31 and the end of the socket 22, and the first permanent magnet and the second permanent magnet are magnetically matched.

[0030] Specifically, the first permanent magnet 32 is fixedly connected to the flange, and the second permanent magnet is fixedly connected to the centrifugal seat 2. When the centrifugal container is inserted into the insertion hole, the flange abuts against the centrifugal container. At this time, the first permanent magnet and the second permanent magnet are magnetically attracted to each other, providing a limiting force on the flange, thereby achieving the effect of axially limiting the centrifugal container, avoiding axial movement of the centrifugal container during movement and generating noise. In addition, the centrifugal container is limited by the magnetic attraction force. When the centrifugal container needs to be removed from the insertion hole, it only needs to apply a pulling force to the centrifugal container to resist the magnetic attraction force and pull it out, which has the advantage of easy disassembly.

[0031] Furthermore, as a preferred embodiment, the flange 31 is integrally provided with the centrifugal container. By means of an integral molding process, the connection strength between the flange 31 and the centrifugal container can be ensured, and the process is easy to form.

[0032] Furthermore, as a preferred embodiment, the first permanent magnet and the second permanent magnet each include a plurality of first permanent magnets and second permanent magnets uniformly arranged around the axis of the jack. The uniform arrangement of the plurality of first permanent magnets and second permanent magnets ensures uniformity of the limiting force and a limiting effect.

[0033] Furthermore, as a preferred embodiment, a plurality of accommodating grooves 310 are evenly spaced around the axis of the flange on a side opposite to the axis of the centrifugal seat, a plurality of first permanent magnets 32 are arranged one by one in the plurality of accommodating grooves 310, and a sealing layer 312 is provided at the port position of the accommodating groove.

[0034] Specifically, it can be understood that the centrifugal container is used to hold water, and water is inevitably spilled during operation. By providing a receiving groove 310 on the side of the flange 31 opposite to the axis of the centrifugal seat, Figure 4 The axis of the plug-in hole is set at an angle, so the side of the flange opposite to the axis of the centrifugal seat is located on the lower surface, thereby reducing the probability of water entering. Further, a sealing layer 312 is set at the port of the receiving groove. The sealing layer can be made of plastic or rubber material and fixed to the mouth of the receiving groove 310 by bonding. The plastic or rubber material has poor magnetic isolation effect, so it will not affect the magnetic attraction effect.

[0035] Furthermore, as a preferred embodiment, a blind groove 311 is coaxially provided at the port position of the accommodating groove 310 , and a sealing layer is provided at the bottom of the blind groove 311 .

[0036] Specifically, it can be understood that the centrifugal seat will rotate at high speed during operation and generate high-frequency vibration. When the sealing layer is in direct contact with the centrifugal seat, the sealing layer will be severely worn. Moreover, it is made of plastic or rubber, and is easily worn by contact and friction with the metal centrifugal seat. When it is worn, the waterproof effect is lost. By setting a blind groove and setting the sealing layer at the bottom of the blind groove 311, the sealing layer will not contact the centrifugal seat, thereby effectively avoiding the wear of the sealing layer and ensuring the sealing effect of the sealing layer.

[0037] Furthermore, as a preferred embodiment, the port of the jack 22 is provided with a plurality of second slots 23, the second permanent magnets are arranged in the second slots 23 in a one-to-one correspondence, and the second permanent magnets partially extend out of the second slots 23 and are plugged into the blind slots 311. Figure 7 The second permanent magnet can be fixed in the second groove 23 by bonding, and the end portion of the second permanent magnet is extended out of the second groove 23. On the one hand, it can prevent water from entering the second groove and staying in the second groove. On the other hand, the end portion of the second permanent magnet is extended into the blind groove, which can reduce the distance with the first permanent magnet and ensure the magnetic attraction effect. On the other hand, the protruding second permanent magnet and the blind groove are plugged in and matched, which can also ensure that the first permanent magnet and the second permanent magnet are in positive correspondence, further ensuring the magnetic attraction effect.

[0038] refer to Figure 7When the centrifugal container is inserted into the insertion hole and the flange abuts against the centrifugal seat, the length of the second permanent magnet extending into the blind groove 311 is less than the depth of the blind groove, so that the end of the second permanent magnet does not contact the sealing layer, thereby avoiding friction between the second permanent magnet and the sealing layer, thereby further avoiding wear of the sealing layer.

[0039] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
