Description

Technical Field

[0001] This utility model relates to the field of centrifugal separator technology, specifically a centrifugal separator for food inspection and testing. Background Technology

[0002] A centrifuge for food testing is a specialized laboratory device used in food quality testing. It primarily separates different components in a sample through centrifugation. This equipment plays a crucial role in food safety testing, especially when detecting microorganisms, residues, additives, and other impurities in food. It effectively separates target substances from complex samples, providing a pure sample for subsequent analysis. The centrifuge works based on centrifugal force. When a sample is placed in a rotating centrifuge tube, as the rotation speed increases, substances are forced to move towards the tube wall due to density differences. Heavier components (such as solid impurities) are thrown to the tube wall, while lighter components (such as liquids or dissolved substances) concentrate at the center. By adjusting the centrifugation speed and time, effective separation of different substances can be achieved.

[0003] The centrifuge used for food inspection and testing has an adjustable support frame, making it unstable when placed, and the plug and connector are not stable during use. Utility Model Content

[0004] The purpose of this utility model is to provide a centrifuge for food inspection and testing, which solves the problems of the centrifuge's non-adjustable support, instability during placement, and unstable plug-connector connection during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrifuge for food inspection and testing, comprising a body, a sliding plate slidably connected inside the body, a sliding rod fixedly connected to the lower end of the sliding plate, a support base fixedly connected to the lower end of the sliding rod, a threaded rod rotatably connected inside the body, a fixed sleeve fixedly connected inside the body, the fixed sleeve and the threaded rod being connected by a bearing, a plug provided on the left side of the body, a connector inserted into the outside of the plug, and a limit mechanism provided on the body.

[0006] Preferably, a fixing rod is fixedly connected inside the body, and the fixing rod is slidably connected to the skateboard. The design of the fixing rod can guide the skateboard.

[0007] Preferably, a knob is fixedly connected to the lower end of the threaded rod, and the knob contacts the bottom of the machine body. The design of the knob allows the threaded rod to be rotated easily.

[0008] Preferably, the limiting mechanism includes a fixing block. The fixing block is fixedly connected to the left side of the machine body and contacts the connector. A limiting sleeve is rotatably connected to the outer side of the fixing block. A protrusion is fixedly connected to the inside of the limiting sleeve. An annular groove is formed inside the fixing block, and a protrusion is slidably connected inside the annular groove. A positioning rod is fixedly connected to the left side of the machine body, and a positioning plate is fixedly connected to the outer side of the connector. By inserting the connector into the plug, the connector drives the positioning plate to engage with the positioning rod. Then, by rotating the limiting sleeve, the limiting sleeve and the connector undergo threaded movement, thereby limiting the connection of the connector to the plug and keeping the connection stable.

[0009] Preferably, the limiting sleeve contacts the machine body, and the limiting sleeve is connected to the connector by a thread. The design of the limiting sleeve can limit the movement of the connector.

[0010] Preferably, the positioning plate is in contact with the limiting sleeve, and the positioning plate is slidably connected to the positioning rod. Through the positioning plate, the design of the positioning plate can play a positioning role for the connector.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up components such as a limiting sleeve, a positioning rod, and a positioning plate, allows the limiting sleeve to limit the connection of the connector when it is plugged in, thus ensuring a stable connection between the connector and the plug. This solves the problems of the non-adjustable support, instability during placement, and unstable plug-connector connection in centrifuges used for food inspection and testing.

[0013] 2. This utility model, by incorporating a sliding plate, a fixed rod, and a threaded rod, allows for the adjustment of the support points of the machine body by rotating the threaded rod, which in turn causes the threaded rod to move in relation to the sliding plate. This ensures the machine body remains stable and solves the problem of the non-adjustable support and instability during use of centrifugal separators for food inspection and testing.

[0024] By inserting the connector 4 into the plug 3, the connector 4 causes the positioning plate 56 to engage with the positioning rod 55. Then, by rotating the limiting sleeve 52, the limiting sleeve 52 and the connector 4 undergo threaded movement, thereby limiting the connector 4 and keeping the connection between the connector 4 and the plug 3 stable.
