Description

Technical Field

[0001] This utility model relates to the field of medical equipment accessories technology, and in particular to the leak-proof structure of medical equipment oil filters. Background Technology

[0002] In the operation of medical equipment (such as the cooling systems of large diagnostic equipment like CT scanners and MRI machines, and the transmission systems of surgical instrument sterilization equipment), oil filters play a crucial role. They filter impurities in the oil, ensuring its cleanliness and thus guaranteeing proper lubrication and heat dissipation of the moving parts of the medical equipment, maintaining stable operation. However, existing medical equipment oil filters often use a single rubber sealing ring for sealing, lacking pressure sealing capabilities, which easily leads to oil leakage. Therefore, a leak-proof structure for medical equipment oil filters is proposed. Utility Model Content

[0003] The present invention aims to provide a leak-proof structure for oil filters in medical equipment, in order to solve the problem mentioned in the background art that existing oil filters in medical equipment mostly use a single rubber sealing ring for sealing during use, which does not have a pressure sealing function, leading to easy oil leakage.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] The leak-proof structure of a medical equipment oil filter includes a base plate, with columns installed at the four corners of the top of the base plate. A fixing frame is installed at the top of each column. A filter tank is installed inside the fixing frame. The top of the filter tank has a tank cover. An outlet pipe is installed at the bottom of the filter tank. An inlet pipe is installed at the top of one side of the filter tank. A fixing ring is installed at the top of the outer side of the filter tank. Several grooves are formed on the outer side of the fixing ring. A locking mechanism for locking the tank cover is provided inside the grooves. A support ring is installed inside the filter tank. A connecting ring is located at the top of the support ring. A filter element is installed inside the connecting ring. A pressure-applying mechanism for pressing down the connecting ring is installed at the bottom center of the tank cover.

[0006] Furthermore, the pressurizing mechanism includes a connecting plate, a telescopic rod is installed at the bottom end of the connecting plate, a pressure plate is installed at the bottom end of the telescopic rod, a crossbar is installed on the outside of the pressure plate, a pressure ring is installed at one end of the crossbar, the bottom end of the pressure ring contacts the top end of the connecting ring, a spring is sleeved on the outside of the telescopic rod, the top end of the spring is fixedly connected to the bottom end of the connecting plate, and the bottom end of the spring is fixedly connected to the top end of the pressure plate.

[0007] Furthermore, the locking mechanism includes a movable hinge, one end of which is fixedly connected to the inner side of the groove, and the other end of which is fitted with a threaded rod. A locking groove is provided on the outer side of the can lid, one end of which passes through the inner side of the locking groove, and a locking nut is fitted on one end of the threaded rod.

[0008] Furthermore, a first sealing groove is provided at the top of the support ring, and a first sealing gasket is installed on the inner side of the first sealing groove.

[0009] Furthermore, a second sealing groove is provided at the bottom of the can lid, and a second sealing gasket is installed on the inner side of the second sealing groove.

[0010] Furthermore, a carrying handle is installed at the top of the can lid.

[0011] Furthermore, support bases are installed at the four corners of the bottom of the base plate, and the bottom of the support bases is provided with anti-slip texture.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] The leak-proof structure of this medical equipment oil filter provides a stable installation foundation for the filter through a base plate, supporting core components such as the column and ensuring the overall structure does not shift. A support bracket is used to build the installation frame for the filter tank, preventing it from directly contacting the ground and becoming damp. The filter tank is fixed inside the support bracket to prevent displacement due to equipment vibration and ensure stable inlet and outlet fluid flow. The filter tank contains the oil and filter element, providing filtration space. The top of the filter tank is sealed by a cap to prevent oil leakage from the top. Inlet and outlet pipes allow for oil flow, adapting to the oil circuit connections of medical equipment. A locking mechanism is installed in the groove of the fixing ring, providing a carrier for locking the cap. The locking mechanism secures the cap, enhancing the seal between the cap and the filter tank. A support ring supports the connecting ring and filter element, ensuring the filter element's stable position. A pressurizing mechanism presses down the connecting ring, improving the fit and seal between the filter element and the support ring. This invention effectively prevents leaks during the oil filtration process, ensuring the cleanliness of the medical equipment oil and operational safety, and has high practical value.
