These facilities simulate actual use conditions and test the product's sealing effectiveness in different environments to prevent the penetration of liquids, gases, or microorganisms, thereby ensuring the safety and effectiveness of medical devices. Sealing testing typically involves pressure testing, vacuum testing, and leak detection to meet relevant industry standards and regulatory requirements.

[0003] Before using the sealing test mechanism for medical device production, clean water will be filled into the barrel, which will increase the weight of the main body. It will be difficult for the staff to operate when they need to rotate the position of the main body. Therefore, the market needs a new device to solve the current problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a sealing detection mechanism for medical device production, so as to solve the problem that the sealing detection mechanism for medical device production proposed in the above background technology is that the inside of the barrel is filled with clean water before use, which increases the weight of the main body. When the staff needs to rotate the position of the main body, it is more difficult to operate. Therefore, the market needs a new device to solve the current problems.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A sealing detection mechanism for medical device production, comprising a main body, a barrel body is installed at the upper end position of the main body, a rubber frame is sleeved on the outer wall position of the barrel body, a sponge is placed at the internal position of the rubber frame, a rotating shaft is fixed at the lower end position of the main body, a plurality of insertion holes are distributed on the outer wall of the rotating shaft at the lower position, a weighted base is sleeved on the outer position of the rotating shaft, a plurality of sleeved balls are sleeved on the inner position of the weighted base, an insertion column is sleeved on the left end position of the weighted base, a fixing plate is fixed on the outer wall position of the insertion column, and a stainless steel spring is fixed on the inner end face position of the fixing plate.

[0006] Preferably, a rubber ring is provided at the upper end of the barrel body, and a barrel cover is installed at the upper end of the barrel body.

[0007] Preferably, the barrel cover is opened and closed by a fixed handle fixed at the upper end, and the barrel cover is connected to the vacuum pump through a vacuum pump connecting pipe at the left side of the upper end.

[0008] Preferably, clean water should be added to the inner position of the barrel of the main body before starting work.

[0009] Preferably, a control panel is provided at the front end of the upper end of the main body.

[0010] Preferably, the main body is rotatable via a rotation shaft, and the rotation shaft rotates at an inner position of the weighted base.

[0011] Preferably, the rotating shaft is fitted on the upper end of the sleeve ball and rotates, and the insertion column is inserted into the inner position of the insertion hole so that the rotating shaft cannot rotate.

[0012] Preferably, the insertion column can move outward, and the movement of the insertion column causes the fixing plate to compress the stainless steel spring.

[0013] Compared with the prior art, the present invention provides a sealing detection mechanism for medical device production, which has the following beneficial effects:

[0014] The main body can be rotated through the rotating shaft at the bottom. During rotation, the insertion column is pulled outward by manual control. The movement of the insertion column causes the fixed plate to compress the stainless steel spring. When the insertion column is disengaged from the insertion hole, the rotating shaft can be rotated at the internal position of the weighted base, and the sleeve ball fits at the lower end position of the rotating shaft, thereby increasing the flexibility of rotation. When the main body is rotated to the appropriate position, the insertion column is released to allow the stainless steel spring to release the compression energy, and the insertion column is inserted into the internal position of the insertion hole, so that the main body is maintained at the current angle. In this way, the main body can be flexibly adjusted.

[0015] The inside of the barrel is filled with clean water for testing samples. When the tested sample is taken out, water droplets will splash into the external position and flow downward along the surface of the barrel. The device is equipped with a rubber frame on the outer wall of the barrel, and a sponge is placed inside the rubber frame. The sponge absorbs the downstream water flow to prevent it from seeping into the internal position of the main body. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] The utility model provides Figure 1-3 The shown embodiment shows a sealing detection mechanism for medical device production, comprising a main body 1, a barrel body 7 being installed at the upper end of the main body 1, a rubber frame 6 being sleeved on the outer wall of the barrel body 7, a sponge 5 being placed inside the rubber frame 6, a rotating shaft 11 being fixed at the lower end of the main body 1, a plurality of insertion holes 13 being distributed on the outer wall of the rotating shaft 11 at the lower position, a weighted base 8 being sleeved on the outer position of the rotating shaft 11, a plurality of sleeved balls 12 being sleeved on the inner position of the weighted base 8, an insertion column 9 being sleeved on the left end position of the weighted base 8, a fixing plate 15 being fixed on the outer wall of the insertion column 9, and a stainless steel spring 14 being fixed on the inner end surface of the fixing plate 15.

[0022] Place the medical device sample to be tested into a barrel 7 filled with clean water. After tightening the lid 4, connect the vacuum pump connection tube 2 to the vacuum pump. Start the vacuum pump and gradually evacuate the air from the barrel 7. This process creates negative pressure within the barrel, and bubbles may appear on the water surface, indicating that the air inside the barrel is being extracted. Set the test program on the main body 1, including parameters such as the vacuum time, negative pressure value, and hold time, ensuring that these parameters meet relevant industry standards and test requirements. After reaching the set negative pressure, maintain it for a period of time to observe whether bubbles are generated. The appearance of bubbles indicates a sample leak. After the test is complete, turn off the vacuum pump, release the negative pressure, open the lid 4, and remove the sample.

[0023] like Figure 2 and Figure 3As shown, a rubber ring 10 is provided at the upper end of the barrel body 7, and a barrel cover 4 is installed at the upper end of the barrel body 7. The barrel cover 4 is opened and closed by a fixed handle 3 fixed at the upper end. The barrel cover 4 is connected to the vacuum pump through the vacuum pump connecting pipe 2 at the left side of the upper end. Before starting the main body 1, clean water should be added to the internal position of the barrel body 7. A control panel is provided at the upper end of the main body 1 at the front position. The main body 1 can be rotated by a rotating shaft 11. The rotating shaft 11 rotates at the internal position of the weighted base 8. The rotating shaft 11 is fitted at the upper end position of the sleeve ball 12 and rotates. The insertion column 9 is inserted into the internal position of the insertion hole 13 so that the rotating shaft 11 cannot rotate. The insertion column 9 can move outward. The movement of the insertion column 9 causes the fixed plate 15 to compress the stainless steel spring 14.

[0024] The insertion column 9 is pulled outward by manual control, and the movement of the insertion column 9 causes the fixing plate 15 to compress the stainless steel spring 14. When the insertion column 9 is disengaged from the insertion hole 13, the rotating shaft 11 can rotate at the internal position of the weighted base 8, and the sleeve ball 12 fits at the lower end position of the rotating shaft 11, thereby increasing the flexibility of rotation. When the main body 1 is rotated to the appropriate position, the insertion column 9 is released to allow the stainless steel spring 14 to release the compression energy, and the insertion column 9 is inserted into the internal position of the insertion hole 13, so that the main body 1 remains at the current angle.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
