[0001] The utility model relates to the technical field of testing equipment, in particular to a testing equipment for a press-type quick-separation pipeline joint. Background Art

[0002] The quick-separation pipeline joint is a common consumable for connecting and disconnecting pipelines in biopharmaceuticals. The elastic button on the female head of the quick-separation pipeline joint is integrally injection-molded from an elastic plastic material and is a vulnerable component of the quick-separation pipeline joint, and its service life needs to be detected. Previously, for the joint.

[0003] In the document CN00804743.X, a two-piece molded female threaded joint is disclosed. By pressing the elastic button located on its female head, the quick separation of the male and female heads can be achieved. However, this kind of joint needs to be tested to determine its service life. In the prior art, the testing equipment tests by imitating the pressing action of a person, and only one joint can be tested at a time. While the efficiency is low, due to the open type of the equipment, it is easy to cause danger to the surrounding area.

[0004] Therefore, a new technical solution is needed to solve the above technical problems. Summary of the Invention

[0005] In order to solve the above problems, the utility model discloses a testing equipment for a press-type quick-separation pipeline joint. By the rotation of an eccentric cam, the key bearing is driven to press the joint to be tested, so as to realize the life detection of the elastic button of the joint to be tested. By driving the eccentric cam with a motor, the test of the elastic button can be realized, which is simple, convenient and fast.

[0006] The technical solution of the utility model is: a testing equipment for a press-type quick-separation pipeline joint, including a joint placement barrel, an eccentric cam and an anti-detachment cover located outside the body shell. The placement barrel is located on the base, and the eccentric cam is driven by a motor inside the body shell. The joint placement barrel is provided with a joint placement cavity and a cam placement chamber. The joint placement cavity is provided with a joint, and the cam placement chamber is provided with an eccentric cam. The eccentric cam is provided with a key bearing, and the elastic button provided on the joint faces the center of the cam placement chamber as a whole.

[0007] By adopting the above technical solution, the joint to be tested is placed into the joint placement cavity, and it is ensured that the elastic button on the joint to be tested faces the center of the joint placement barrel. When the eccentric cam rotates, the key bearing is driven to press the joint to be tested, so as to realize the pressing test of the key bearing.

[0008] Preferably, the cam placement chamber is located at the central position of the joint placement barrel. The joint placement cavity surrounds the cam placement chamber in a circular shape centered on the center of the joint placement barrel, and the circle formed by the cam placement chamber and the joint placement cavity is concentric.

[0009] By adopting the above technical solution, the joint placement cavity is circular and concentric with the cam placement chamber. In this way, when the eccentric cam rotates, the key bearing on the eccentric cam can just press the joint to be tested in the joint placement cavity.

[0010] Preferably, the joint placement barrel is connected to the body shell by bolts arranged circumferentially and passing through the thickness of the joint placement barrel. Correspondingly, the front end of the body shell has bolt holes, the outer surface of the front end of the joint placement barrel is provided with external threads, and the inner side of the anti - detachment cover is provided with internal threads adapted to the external threads.

[0011] By adopting the above technical solution, the anti - detachment cover is tightened by the adaptation of the internal threads and the external threads outside the joint placement barrel, and is screwed on the front end of the joint placement barrel. The anti - detachment cover can cover the joint placement cavity with the joint to be tested placed therein, preventing the joint to be tested from flying out accidentally under the extrusion of the eccentric cam during the test.

[0012] Preferably, the camshaft of the eccentric cam is eccentrically arranged at the rear end of the eccentric cam. The camshaft is connected to the output shaft of the motor through a coupling. The rotation of the motor drives the rotation of the eccentric cam. A coupling protective sleeve is arranged outside the coupling. The rear end of the coupling protective sleeve is fixed to the body shell by bolts. The front end of the coupling protective sleeve has a shaft - passing opening. The camshaft is connected to the shaft - passing opening of the coupling protective sleeve outside the coupling through a shaft - passing bearing. A circlip is arranged on the camshaft inside the coupling protective sleeve at the rear end of the shaft - passing bearing.

[0013] By adopting the above technical solution, the coupling protective sleeve protects the connecting components of the coupling. The circlip arranged at the rear end of the shaft - passing bearing can prevent the shaft - passing bearing and the previous components from moving towards the motor direction during the operation of the device.

[0014] Preferably, the joint placement cavity and the joint are mutually adapted. The side of the joint placement cavity is provided with a limiting groove imitating the elastic key. The elastic key just snaps into the limiting groove, and all the limiting grooves face the center of the cam placement chamber.

[0015] By adopting the above technical solution, when the joint is placed in the joint placement cavity, the elastic keys on the joint all face the center of the cam placement chamber exactly. In this way, when the key bearing rotates with the eccentric cam, it can just press the elastic keys.

[0016] Preferably, a cam negative counterweight is provided on the eccentric cam. By opening a hole in the eccentric cam, the center of gravity of the eccentric cam is adjusted to the axis where the camshaft is located.

[0017] By adopting the above technical solution, the cam negative counterweight, i.e., the hole, formed on the eccentric cam can reduce the weight in front of the eccentric cam, shift the center of gravity of the eccentric cam to the axis where the camshaft is located, and prevent the situation of top-heaviness.

[0018] Preferably, a key bearing is sleeved circumferentially on the eccentric cam. When the eccentric cam rotates, the key bearing sequentially presses the connectors placed in the connector placement cavity.

[0019] By adopting the above technical solution, the key bearing can drive the key bearing to perform eccentric rotation as the eccentric cam rotates, and then press the connector to be measured located in the connector placement cavity. Since the key bearing position is a bearing, it will not cause significant wear to the key surface of the connector.

[0020] Preferably, clamping grooves are arranged on the outer circumferences at the front end and the rear end of the eccentric cam, i.e., the clamping grooves are located on both sides of the key bearing. A snap ring is clamped in the clamping grooves on both sides of the eccentric cam. There are matching grooves between the outer circumference of the eccentric cam and the inner circumference of the key bearing, and the key bearing and the eccentric cam are fastened by a bolt.

[0021] By adopting the above technical solution, the clamping grooves are exactly used for clamping the snap ring. The snap rings on both sides exactly clamp the key bearing in the middle, preventing the axial movement of the key bearing and the eccentric cam. Fastening the key bearing and the eccentric cam with a bolt can prevent the key bearing from having axial movement.

[0022] Preferably, the base is inclined at an angle less than 45 degrees. The body shell is placed on the base, and its connector placement barrel is inclined upward. A shock-absorbing and anti-slip pad is provided at the bottom of the base, and a handle is provided at the upper part of the body shell.

[0023] By adopting the above technical solution, the connector placement barrel needs to be placed obliquely upward so that the opening of the connector placement cavity faces obliquely upward, facilitating the placement of the connector. During the placement process, the connector will not slide down. After being placed, there is a lid, so it will naturally not slide down. The oblique upward placement is achieved by setting a base under the body shell. The front end of the base is higher than the rear end. After being installed on the body shell, the front part of the device will be raised. An anti-slip pad is provided under the base to prevent sliding on the workbench surface.

[0024] Preferably, a power supply module for supplying power to the motor is provided on the base.

[0025] By adopting the above technical solution, when the body shell is placed on the base, the power supply module on the base supplies power to the motor.

[0026] Advantages of the present utility model: 1. By rotating the eccentric cam, the present utility model drives the key bearing to press the joint to be tested, realizing the life test of the elastic key of the joint to be tested. By driving the eccentric cam with a motor, the test of the elastic key can be realized, which is simple, convenient and fast.

[0027] 2. The elastic keys of the present utility model are all oriented towards the center of the cam placement chamber. In this way, when the motor drives the eccentric cam to perform eccentric motion, the elastic keys can be pressed evenly, ensuring that the force received by each elastic key is the same, reducing the variables in the joint test, and improving the test accuracy.

[0028] 3. By arranging snap rings at the front end and the rear end of the eccentric cam, the present utility model can effectively prevent the axial movement of the key bearing and the eccentric cam. The outer periphery of the eccentric cam and the key bearing are fastened with bolts to prevent the axial movement of the key bearing. A snap ring is arranged at the rear end of the shaft-bearing to prevent the shaft-bearing and the previous components from moving towards the motor direction.

[0029] 4. The present utility model is provided with an anti-disengagement cover outside the joint placement barrel, which can prevent the joint to be tested from flying out accidentally under the extrusion of the eccentric cam during the test, playing a role in protecting the on-site staff and ensuring the safety of the staff.

Detailed implementation

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] As Figures 1-5 shown, a test device for a push-button quick-disconnect pipeline connector includes a connector placement barrel 1, a connector 6, an eccentric cam 2, and an anti-detachment cover 8 located outside the body shell 9. The placement barrel is located on the base, and the eccentric cam 2 is driven by a motor 10 inside the body shell 9. The connector placement barrel 1 is provided with a connector placement cavity 1-2 and a cam placement chamber 1-1. The connector 6 is located in the connector placement cavity 1-2, and the eccentric cam 2 is provided in the cam placement chamber 1-1. A button bearing 3 is provided on the eccentric cam 2, and the elastic button 6-1 provided on the connector 6 faces the center of the cam placement chamber 1-1 as a whole. The to-be-tested connector 6 is placed into the connector placement cavity 1-2, and it is ensured that the elastic button 6-1 on the to-be-tested connector 6 faces the center of the connector placement barrel 1. When the eccentric cam 2 rotates, it drives the button bearing 3 to press the to-be-tested connector 6 to achieve the pressing test of the button bearing 3.

[0038] The cam placement chamber 1-1 is located at the central position of the connector placement barrel 1. The connector placement cavity 1-2 is circularly surrounded around the cam placement chamber 1-1 with the center of the connector placement barrel 1 as the center. The circle formed by the cam placement chamber 1-1 and the connector placement cavity 1-2 is concentric. The connector placement cavity 1-2 is circular and concentric with the cam placement chamber 1-1. In this way, when the eccentric cam 2 operates, the button bearing 3 on the eccentric cam 2 can just press the to-be-tested connector 6 in the connector placement cavity 1-2.

[0039] The joint placement barrel 1 is connected to the body housing 9 by bolts circumferentially arranged and passing through the thickness of the joint placement barrel 1. Correspondingly, the front end of the body housing 9 has bolt holes 9-2, the outer surface of the front end of the joint placement barrel 1 is provided with external threads 1-3, the inner side of the anti-disengagement cover 8 is provided with internal threads 8-1 adapted to the external threads 1-3, and the anti-disengagement cover 8 is screwed tightly by the adaptation of the internal threads 8-1 and the external threads 1-3 outside the joint placement barrel 1 and is screwed onto the front end of the joint placement barrel 1. The anti-disengagement cover 8 can cover the joint placement cavity 1-2 where the joint 6 to be tested is placed, preventing the joint 6 to be tested from flying out accidentally under the extrusion of the eccentric cam 2 during the test.

[0040] The camshaft 2-1 of the eccentric cam 2 is eccentrically arranged at the rear end of the eccentric cam 2. The camshaft 2-1 is connected to the output shaft of the motor 10 through a coupling 10-1. The rotation of the motor 10 drives the rotation of the eccentric cam 2. An outer coupling protection sleeve 7 is provided outside the coupling 10-1. The rear end of the coupling protection sleeve is fixed to the body housing 9 by bolts. The front end of the coupling protection sleeve 7 has a shaft-passing opening. The camshaft 2-1 is connected to the shaft-passing opening of the coupling protection sleeve 7 outside the coupling 10-1 through a shaft-passing bearing 7-1. A snap ring 4 is arranged on the camshaft 2-1 inside the coupling protection sleeve 7 at the rear end of the shaft-passing bearing 7-1. The coupling protection sleeve 7 protects the connecting components of the coupling 10-1. The snap ring 4 arranged at the rear end of the shaft-passing bearing 7-1 can prevent the shaft-passing bearing 7-1 and the previous components from moving towards the motor 10 during the operation of the device.

[0041] The joint placement cavity 1-2 and the joint 6 are mutually adapted. The end of the joint 6 is slightly larger than the joint placement cavity 1-2. When the joint 6 is inserted into the joint placement cavity 1-2, the end of the joint 6 is just stuck into the joint placement cavity 1-2, and the joint 6 is not easily slipped out. The side of the joint placement cavity 1-2 is provided with a limiting groove 1-21 imitating the elastic key 6-1. The elastic key 6-1 is just stuck into the limiting groove 1-21. The limiting grooves 1-21 all face the center of the cam placement chamber 1-1. In this way, when the joint 6 is placed into the joint placement cavity 1-2, the elastic keys 6-1 on the joint 6 all just face the center of the cam placement chamber 1-1. In this way, when the key bearing 3 rotates with the eccentric cam 2, it can just press the elastic key 6-1.

[0042] A cam negative counterweight 2-3 is opened on the eccentric cam 2. By opening a hole in the eccentric cam 2, the center of gravity of the eccentric cam 2 is coordinated to the axis where the camshaft 2-1 is located. The cam negative counterweight 2-3 opened on the eccentric cam 2, that is, the hole, can reduce the weight in front of the eccentric cam 2 and transfer the center of gravity of the eccentric cam 2 to the axis where the camshaft 2-1 is located, preventing the situation of top-heavy and bottom-light.

[0043] The eccentric cam 2 is circumferentially sleeved with the key bearing 3. When the eccentric cam 2 rotates, the key bearing 3 sequentially presses the connector 6 placed in the connector placement cavity 1-2. The key bearing 3 can drive the key bearing 3 to perform eccentric rotation as the eccentric cam 2 rotates, and then press the connector 6 to be tested located in the connector placement cavity 1-2. Since the key bearing 3 is a bearing, it will not cause significant wear to the key surface of the connector 6.

[0044] The outer circumference of the front end and the rear end of the eccentric cam 2 is provided with clamping grooves 2-2, that is, the clamping grooves 2-2 are located on both sides of the key bearing 3. The snap rings 4 are clamped in the clamping grooves 2-2 on both sides of the eccentric cam 2. The outer circumference of the eccentric cam 2 and the inner circumference of the key bearing 3 have matching grooves. The key bearing 3 and the eccentric cam 2 are fastened by the bolt 5. The clamping grooves 2-2 are just used to clamp the snap rings 4, and the snap rings 4 on both sides just clamp the key bearing 3 in the middle to prevent the axial movement of the key bearing 3 and the eccentric cam 2. Fastening the key bearing 3 and the eccentric cam 2 with the bolt 5 can prevent the key bearing 3 from having axial movement.

[0045] The base 11 is inclined at an angle less than 45 degrees. The body shell 9 is placed on the base 11, and its connector placement barrel 1 is inclined upward. The bottom of the base 11 is provided with a shock-absorbing and anti-slip pad 12. The upper part of the body shell 9 is provided with a handle 9-1. The connector placement barrel 1 needs to be placed obliquely upward so that the opening of the connector placement cavity 1-2 faces obliquely upward, which is convenient for placing the connector 6. During the process, the connector 6 will not slide off. After it is placed well, there is a cover, and naturally it will not slide off. The oblique upward placement is achieved by setting the base 11 below the body shell 9. The front end of the base 11 is higher than the rear end. After being installed on the body shell 9, the front part of the device will be raised. The rear anti-slip pad is set under the base 11 to prevent it from sliding on the workbench surface.

[0046] The base 11 is provided with a power module 13 for supplying power to the motor 10. When the body shell 9 is placed on the base 11, the power module 13 on the base 11 supplies power to the motor 10.

[0047] The motor 10 drives the eccentric cam 2 to perform eccentric motion, and the key bearing 3 on the eccentric cam 2 also performs eccentric motion accordingly. When the key bearing 3 performs eccentric motion, it just presses the elastic key 6-1 on the connector 6 located in the connector placement cavity 1-2 to test the elastic key 6-1. At the same time, the anti-detachment cover 8 tightened outside the connector placement barrel 1 can prevent the connector 6 to be tested from accidentally flying out under the extrusion of the eccentric cam 2 during the test. Start the power supply, set the test time or the number of presses, and the motor starts to rotate. Every time the motor shaft rotates one circle, it will drive the eccentric cam 2 to rotate one circle, and at the same time the key bearing 3 rotates one circle. At this time, the key shaft 3 will press the elastic key 6-1 of each connector 6 to be tested once.

[0048] When the test time or the number of presses is reached, the motor 10 stops rotating and the test ends.
