[0023] Reference Figures 1 to 3 This application provides a centrifuge device for oil detection, comprising: a casing 100, which is provided with a centrifuge chamber 110; a rotor 200, which is rotatably disposed in the centrifuge chamber 110, the rotor 200 is connected to a motor 210, the rotor 200 is provided with a socket 220, and a buffer 230 is provided at the bottom of the socket 220; an adjustment mechanism 300, which includes a plurality of fixing plates 310, which are movably disposed in the socket 220, and are arranged circumferentially so as to be able to approach or move away from each other, and the plurality of fixing plates 310 cooperate to fix the sample tube; and a pressure cap 400, which is placed on top of the rotor 200 and is fixedly connected to the rotor 200.

[0024] By movably setting the fixing plate 310 in the insertion hole 220, multiple fixing plates 310 can be brought closer together or moved away from each other, thereby adjusting the size of the insertion hole 220 to accommodate sample tubes of different specifications, expanding the scope of application, facilitating operation, and improving work efficiency; by setting a buffer 230 at the bottom of the insertion hole 220, the bottom of the sample tube can be prevented from being damaged by impact when forcefully inserting the sample tube, providing a certain degree of protection for the bottom of the sample tube, and improving stability and safety.

[0025] The buffer 230 is configured as a buffer pad or an abutment piece connected by a spring 330, and this application does not limit this.

[0026] Reference Figures 1 to 3 Furthermore, the fixing plate 310 is provided with a guide rod 320, which slides through the side wall of the insertion hole 220. A spring 330 is sleeved on the guide rod 320, and both ends of the spring 330 abut against the side wall of the insertion hole 220 and the fixing plate 310, respectively. By adopting the above structure, adaptive adjustment according to the sample tube can be achieved without manual operation, improving work efficiency. The fixing plates 310 have an arc surface on their adjacent sides, and a protective pad is provided on the arc surface. The arc surface increases the contact area with the sample tube, improving the stability of the sample tube; the protective pad further protects the sample tube, enhancing its protective effect.

[0027] It should be noted that the fixing piece 310 can also be configured as a V-shaped structure, in which case only two fixing pieces 310 need to be symmetrically arranged. Those skilled in the art can make reasonable choices regarding the shape and number of the fixing pieces 310 according to the actual situation, and this application does not impose any restrictions on this.

[0028] It should also be noted that the fixing plate 310 may also be equipped with a screw, which rotates through the side wall of the insertion hole 220. By rotating the screw, the fixing plate 310 is moved, thereby causing the fixing plates 310 to move closer together or further apart; alternatively, the fixing plate 310 may be directly set as an elastic plate, using its own elasticity to achieve adaptive adjustment of the sample tube. This application does not limit the structural configuration of the adjustment mechanism 300.

[0029] In this embodiment, the rotor 200 has a threaded head at its top, and the gland 400 is disposed in the threaded hole, with the threaded head and threaded hole engaging. A sealing element is provided between the gland 400 and the rotor 200 to improve sealing performance. The gland 400 prevents the sample tube from accidentally flying out under centrifugal force, ensuring safety and stability. Connecting the gland 400 and rotor 200 via the threaded head and threaded hole not only makes the connection more secure but also facilitates operation and improves work efficiency. Furthermore, an operating nut 410 is provided at the top of the gland 400, facilitating rotation of the gland 400 to establish a threaded connection between the gland 400 and rotor 200, further improving work efficiency.

[0030] Reference Figure 1It is conceivable that a cover 120 is provided at the opening of the centrifuge chamber 110. The rear end of the cover 120 is hinged to the casing 100, and the front end of the cover 120 is connected to the casing 100 via a latch 130. By providing the cover 120, the centrifuge chamber 110 can be sealed to prevent foreign objects from affecting the rotation of the rotor 200, while also protecting the operator and improving stability and safety. The cover 120 is provided with an observation hole 140, which can be sealed with a transparent sheet, which can be made of glass or resin, to facilitate observation of the conditions inside the centrifuge chamber 110.

[0031] It should be noted that the latch 130 can be set as an electronic latch 130 or a mechanical latch 130, and this application does not limit it.

[0032] Reference Figure 1 In some embodiments of this application, the centrifuge device for oil detection further includes a control mechanism, which is disposed in the casing 100. The control mechanism includes a timer and a controller. The timer is connected to the motor 210, and the controller is connected to both the timer and the motor 210. The casing 100 is provided with a start switch, which is connected to the controller, the motor 210, and the timer. An operation panel 150 is provided on the outer wall of the casing 100 and is connected to the controller. By providing the operation panel 150, the rotation speed and rotation time of the motor 210 can be set to meet different detection requirements. Simultaneously, the current working status can be viewed in real time through the operation panel 150, improving work efficiency.

[0033] It should be noted that the controller's control method is simply trigger control. Therefore, the controller's control method is not within the scope of protection of this application and belongs to the prior art. This application mainly protects the connection relationship between the various components.

[0034] In this embodiment, multiple insertion holes 220 are provided, symmetrically arranged on the rotor 200. Sample tubes need to be inserted symmetrically into the insertion holes 220 to ensure balance. By providing multiple insertion holes 220, the grease in multiple sample tubes can be detected simultaneously, improving detection efficiency. Furthermore, the control mechanism includes an alarm. An imbalance detector is installed in the centrifuge chamber 110, connected to the alarm and controller respectively. The alarm is also connected to the motor 210 and controller respectively. The imbalance detector is used to detect the balance of the rotor 200. When the imbalance detector detects an imbalance in the rotor 200, it sends a signal to the controller and triggers the alarm to alert the operator. At this time, the motor 210 also stops operating until the rotor 200 is balanced. By adopting the above structure, detection accuracy and work efficiency can be improved.

[0035] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
