Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0036] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0037] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] refer to Figures 1 to 7 This application provides a measuring device 100 for measuring the installation resistance of the adapter of a negative pressure drainer. The measuring device 100 is capable of measuring the resistance of the adapter of the negative pressure drainer 200 when it is installed on the top cover.

[0040] The negative pressure drainage device 200 includes a top cover 202 of a flexible bag. One end of the flexible bag has an opening, and the top cover 202 is disposed at the opening. The end of the flexible bag with the opening is thermally bonded to the top cover 202. The negative pressure drainage device 200 further includes an adapter 203. The top cover 202 has a pre-set position with an insertion hole 2021 communicating with the flexible bag. The adapter 203 is adapted to be inserted into the insertion hole 2021 to communicate with the space inside the flexible bag. The adapter 203 is also adapted to communicate with an external pipe so that external liquid can enter the interior of the flexible bag through the external pipe.

[0041] The measuring device 100 for measuring the installation resistance of the adapter for the negative pressure drainage device provided in this application is specifically capable of measuring the resistance when the adapter 203 is inserted into the insertion hole 2021 of the top cover 202.

[0042] Specifically, the measuring device for the installation resistance of the adapter for the negative pressure drainage device includes a lifting mechanism 10, a force gauge 20, a push rod 30, and a bottom support mechanism 40. The lifting mechanism 10 includes a guide rail 11 and a slider 12, the slider 12 being slidably mounted on the guide rail 11. The top of the force gauge 20 is mounted on the slider 12. The top of the push rod 30 is mounted on the force gauge 20. The bottom support mechanism 40 includes a support plate 41 and several support columns 42, the support columns 42 being mounted on the bottom of the support plate 41. The bottom of the support plate 41 has a clearance space 410, and the support plate 41 has an installation opening 411 communicating with the clearance space 410. The top cover 202 is mounted on the installation opening 411. The adapter 203 is located on the movement path of the push rod 30. During the downward movement of the lifting mechanism 10, which drives the force gauge 20 and the push rod 30, the end of the push rod 30 away from the force gauge 20 is adapted to abut against the adapter 203, pushing one end of the adapter 203 into the insertion hole 2021 of the top cover 202. As the push rod 30 pushes the adapter 203, the top cover 202 applies a counterforce to the adapter 203, which, through the push rod 30, acts on the force gauge 20. Thus, the force gauge 20 can measure the resistance when the adapter 203 is inserted into the insertion hole 2021 of the top cover 202.

[0043] The mounting opening 411 is set at a preset position on the support plate 41, which can avoid the protruding structure of the top cover 202 away from the adapter 203, so that the top cover 202 is placed stably on the surface of the support plate 41.

[0044] refer to Figure 4 Furthermore, the top of the support plate 41 has a support ring 412, and the support ring 412 is arranged around the mounting opening 411. The bottom edge of the top cover 202 has a first limiting ring 2022 and a second limiting ring 2023 spaced apart, and a limiting groove 2020 is formed between the first limiting ring 2022 and the second limiting ring 2023. The top of the support ring 412 is installed in the limiting groove 2020. When the support ring 412 is installed in the limiting groove 2020, the first limiting ring 2022 and the second limiting ring 2023 are respectively located on both sides of the support ring 412, and can respectively limit the support ring 412 on both sides, thereby improving the stability of the top cover 202 when it is installed on the support plate 41.

[0045] The bottom support mechanism 40 also includes a traction plate 43, the bottoms of which are mounted on the traction plate 43, forming the clearance space 410 between the traction plate 43 and the support plate 41. The support columns 42 are spaced apart from each other between the support plate 41 and the traction plate 43.

[0046] The side of the support plate 41 has a plurality of outwardly extending mounting arms 413, which respectively extend to the top of the plurality of support columns 42, and the mounting arms 413 are detachably mounted to the support columns 42.

[0047] refer to Figure 7 In some embodiments, the bottom of the push rod 30 has a receiving groove 31 adapted to the adapter 203, and when the bottom of the push rod 30 contacts the adapter 203, the adapter 203 is adapted to enter the receiving groove 31. The cooperation between the receiving groove 31 and the adapter 203 improves the stability of the push rod 30 when it abuts against the adapter 203, and reduces the risk of the push rod 30 sliding relative to the adapter 203.

[0048] Preferably, the support plate 41 is a circular sheet structure, the mounting opening 411 is circular, and the mounting opening 411 is eccentrically positioned relative to the support plate 41. The insertion hole 2021 is also located on one side of the top cover 202. When the top cover 202 is installed on the support plate 41, the insertion hole 2021 and the support plate 41 roughly correspond to the middle area of ​​the support plate 41, so as to better correspond with the push rod 30.

[0049] Preferably, the bottom support mechanism 40 further includes a plurality of pulling members 44 disposed on the side of the pulling plate 43 away from the top cover 202, and the plurality of pulling members 44 are correspondingly disposed with a plurality of support columns 42. A lug 431 is provided on the side of the pulling plate 43 away from the top cover 202 corresponding to the position of the pulling member 44. Each pulling member 44 includes a base 441 and a telescopic rod 442. The top of the telescopic rod 442 is rotatably connected to the lug 431, and the bottom of the telescopic rod 442 is telescopically mounted on the base 441. Operating the pulling member 44 can control the lifting and lowering of the pulling plate 43 to adjust the height of the top cover 202. During testing, while operating the lifting mechanism 10 to drive the push rod 30 to press the adapter 203 downwards, operating the pulling member 44 can simultaneously drive the top cover 202 to move, thereby pushing the adapter 203 and the top cover 202 from two opposite directions respectively, improving measurement efficiency.

[0050] Preferably, there are multiple pulling members 44, and the multiple pulling members 44 are arranged at intervals. During the measurement process, the placement angle of the support plate 41 can be adjusted by adjusting the pulling members 44, so that there is a certain tilt angle between the adapter 203 and the insertion hole 2021. This can better simulate the working condition when the adapter 203 is inserted into the insertion hole 2021 in actual operation, because when the adapter 203 is actually inserted into the insertion hole 2021, there will inevitably be a certain tilt angle between the adapter 203 and the insertion hole 2021.

[0051] Specifically, the telescopic rod 442 includes a bottom telescopic rod 4421 and a top telescopic rod 4422. The bottom of the bottom telescopic rod 4421 is telescopically mounted to the base 441, and the top of the top telescopic rod 4422 is rotatably mounted to the lug 431. The top of the bottom telescopic rod 4421 has a receiving groove, and the bottom of the top telescopic rod 4422 is mounted in the receiving groove. Preferably, the bottom of the top telescopic rod 4422 and the top of the bottom telescopic rod 4421 are connected to each other by a threaded connection.

[0052] Furthermore, the lifting mechanism 10 also includes a horizontal mounting plate 13 and a vertical reinforcing plate 14. One end of the horizontal mounting plate 13 is mounted to the slider 12, and the other end extends away from the slider 12. The vertical reinforcing plate 14 is mounted to the slider 12, located below the horizontal mounting plate 13, and its top abuts against the horizontal mounting plate 13. The force gauge 20 is mounted on the end of the horizontal mounting plate 13 away from the slider 12. The horizontal mounting plate 13 extends outward from the slider 12 by a certain distance, providing sufficient space below the horizontal mounting plate 13 to mount the force gauge 20. The vertical reinforcing plate 14, located below the horizontal mounting plate 13, provides support for the horizontal mounting plate 13, improving the stability of its installation.

[0053] refer to Figure 1 and Figure 2 The measuring device 100 for measuring the installation resistance of the adapter for the negative pressure drainage device further includes a base plate 50 and a control box 60. The lifting mechanism 10, the bottom support mechanism 40, and the control box 60 are all mounted on the base plate 50. The control box 60 is connected to the lifting mechanism 10, the bottom support mechanism 40, and the force meter 20. Operating the control box 60 can control the lifting of the lifting mechanism 10 and the lifting of the bottom support mechanism 40.

[0054] The bottom support mechanism 40 further includes a control block 45, the outlet of which is adapted to be connected to the inlet of the base 441 via a pipe, and the outlet of the base 441 to be connected via a pipe. Preferably, the pulling member 44 is a hydraulic rod, and fluid can flow between the control block 45 and the base 441 through the pipe between the control block 45 and the base 441, thereby controlling the extension and retraction of the telescopic rod 442 relative to the base 441. The fluid can be either a liquid or a gas. It is understood that in some modified embodiments, the pulling member 44 can also be implemented as other devices capable of pulling the pulling disc 43, including but not limited to motors, cylinders, etc., as long as the effect of driving the pulling disc 43 to move can be achieved, the specific type of the pulling member 44 should not constitute a limitation of this application.

[0055] The bottom support mechanism 40 further includes a pressure regulating valve connecting the control block 45 and the outside, used to regulate the pressure of the fluid output by the control block 45 to the pulling member 44.

[0056] Preferably, the guide rail 11 is a servo guide rail, integrating a motor connected to the slider 12 and the control box 60. Operating the control box 60 controls the motor to move the slider 12. The control box 60 is communicatively connected to the control block 45 of the bottom support mechanism 40. Operating the control box 60 can control the flow of fluid between the control block 45 and the pulling member 44, thereby controlling the raising and lowering of the telescopic rod 442 relative to the base 441.

[0057] The control box 60 is also equipped with a display screen at a preset position. The force meter 20 is communicatively connected to the control box 60. During the test, the value of the force meter 20 can be displayed in real time on the display screen of the control box 60.
