Abstract
Description
Technical Field
[0001] This utility model relates to the field of airtightness testing in endoscope production, and in particular to a universal testing device for sealing performance. Background Technology
[0002] Air tightness testing is necessary during the production of endoscopes because endoscopes are used to enter the patient's body. If the endoscope cannot maintain air tightness, liquids or gases may enter the patient's body, causing infection, pain, or even life-threatening situations. Using a testing device to ensure air tightness also guarantees a clear image.
[0003] Many existing general-purpose sealing performance testing devices used for endoscope production testing often fail to allow operators to perform the tests in an easy manner. The pressure gauge and air bladder need to be held in hand, making the series of testing steps inconvenient. Testing for air tightness requires manually squeezing the air bladder for several seconds. During the squeezing process, the air bladder will immediately return to its original position once the force is released, which will greatly affect the test results and make it impossible to effectively test the true air tightness. At the same time, squeezing the air bladder and maintaining the squeezed state also consumes the operator's physical strength. When dealing with a large number of endoscope testing tasks, this will cause the operator's hand to ache, thereby reducing the testing efficiency.
[0004] Therefore, those skilled in the art have provided a universal testing device for sealing performance to solve the problems mentioned in the background art. Utility Model Content

[0016] 1. This utility model proposes a universal sealing performance testing device. The device is equipped with two sets of sliding support plates that can slide on corresponding straight plates. A pressure gauge and the bottom of the air bladder can be clamped onto both sliding support plates. For ease of use, the position can be adjusted by sliding, eliminating the need for long-term hand operation. The device is flexible in operation. At the start of the test, the slider can be dragged to one side, and then the rotating disk can be rotated. The rotation of the rotating disk will cause the large gear to drive the two rack blocks and the compression plate to move, compressing the air bladder. After the compression is in place, the slider can be released. Under the elastic action of the return spring, it is clamped on the ruler of the rotating disk to limit its position. At this time, the air bladder can be maintained in a compressed state. There is no need for long-term manual maintenance, which greatly saves the physical strength of the testing personnel and improves the testing efficiency.

Two telescopic blocks 206 are slidably installed through the lower end of the suspension plate 201 on both sides.
[0030] The lower end of the suspension plate 201 is provided with a retaining plate on both sides. Each pair of adjacent telescopic blocks 206 are slidably disposed inside the retaining plates on both sides. A spring is provided between each telescopic block 206 and the retaining plate. Each limit block 205 is provided with a limit groove on both sides. The overall dimensions of the telescopic blocks 206 are consistent with the internal dimensions of the limit groove.

The upper end of the two bearing parts is provided with grooves that can support the bottom of the pressure gauge 601 and the airbag 603, respectively.
[0031] Specifically, the lower ends of the pressure gauge 601 and the airbag 603 can slide from the other side onto the corresponding sliding bearing plate 204. When the suspension plate 201 is in a horizontal position, the multiple telescopic blocks 206 at its lower end are in a compressed state. After rotating 90°, the multiple telescopic blocks 206 are located in the limiting groove area of the limiting block 205. At this time, the multiple telescopic blocks 206 are reset by the action of the internal spring, thereby fixing the suspension plate 201 in a vertical state.
[0032] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6 The testing mechanism 6 includes an upper top plate 602, a pressure gauge 601, a three-way pipe 607, and an air pipe 606. An airbag 603 is provided at the lower end of the upper top plate 602. A rotating disk 610 is rotatably provided at the upper end of the upper top plate 602 near the center. An internal gear 614 is fixedly provided at the lower end of the rotating disk 610. A rack block 613 is slidably engaged with both sides of the upper bottom of the upper top plate 602 near the internal gear 614. A pressing plate 605 is fixedly provided at the lower end of both rack blocks 613. A fixing body 611 is fixedly provided at the upper end of the upper top plate 602 near the rotating disk 610. A slider 609 is slidably engaged with inside the fixing body 611. A return spring 612 is provided between one side of the slider 609 and the fixing body 611.
[0033] The internal gear 614 is rotatably mounted at the center of the upper end of the bottom of the top plate 602. The internal gear 614 meshes with two adjacent rack blocks 613. The lower end of the airbag 603 is equipped with a vent valve 604. The three-way pipe 607, pressure gauge 601 and airbag 603 are all connected through the air pipe 606.

[0034] Specifically, the rotating disk 610 is provided with multiple straight rods around its body, and the slider 609 has a groove on the side near the support rod. This groove allows the slider 609 to be fitted onto the support rod. The slider 609 is provided with levers at both the front and rear ends, and the levers are located in the front and rear end grooves of the fixed body 611.
[0035] Working principle: Before use, the flip cover 3 can be opened, and then the suspension plate 201 can be rotated 90°. At this time, the telescopic blocks 206 will be located in the limiting groove area of the limiting block 205. The vertical fixation of the suspension plate 201 can be achieved by resetting the limiting block 205. At this time, the pressure gauge 601 and the air bag 603 can be slidably placed on the corresponding sliding bearing plate 204. After suspension, the detection work can be realized.
[0036] Secondly, when using the device, the connecting connector 608 can be connected to the ventilation end of the endoscope. Then, the slider 609 is pulled to one side and the rotating disk 610 is rotated. The rotation of the rotating disk 610 will drive the two rack blocks 613 to move through the internal gear 614. At this time, the two compression plates 605 will compress the airbag 603. When the slider 609 is released, under the action of the return spring 612, it can be locked around the support rod of the rotating disk 610 to limit its movement and maintain the compressed state of the airbag 603. At this time, the change of the pressure gauge 601 can be observed to determine the airtightness of the endoscope. After use, the detection mechanism 6 can be placed in the recycling tank 7 for storage.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
