Technical Field

[0001] The invention relates to the technical field of air tightness detection, in particular to an air tightness detection device for a silicone drainage tube. Background Art

[0002] Silicone tubes are carriers for the circulation and coating of liquids, gases and other materials. In the industry, silicone rubber tubes can be divided into "extruded tubes" and "special-shaped tubes". They are widely used in modern industry, defense industry, medical treatment and daily necessities. In the production of silicone tubes, the airtightness of silicone tubes is an important indicator of their quality, so they need to be tested.

[0003] After searching, Chinese patent application No. 201721910882.0 discloses an insertable drainage tube air tightness test device. The insertable drainage tube air tightness test device includes a base and a connecting pipeline for connecting to the air nozzle on the drainage tube. The base is provided with a blocking device for blocking the opening corresponding to the corresponding air nozzle on the air distribution pipe of the drainage tube. The connecting pipeline has an air source interface for connecting to a negative pressure source or a pressure source and a pressure maintaining valve for controlling the on-off of the connecting pipeline. An air pressure detection device is provided on the side of the pressure maintaining valve on the connecting pipeline away from the air source interface. The inspection device in this patent can test the air tightness of the drainage tube, but has the following shortcomings:

[0004] 1. The single method for detecting the air tightness of the drainage tube results in low detection accuracy;

[0005] 2. The connection of the end of the drainage tube is not convenient enough, and the sealing of the connection is not good, which affects the test results;

Embodiment 2

[0043] See also Figure 8 , 9 In order to make the connection between the silicone drainage tube and the interface tube 1 612 and the interface tube 2 613 more convenient and with better sealing, this embodiment adds the following scheme on the basis of the embodiment 1:

An extrusion plate 619 is provided on the side of the driving plate 609 away from the cylinder 611. When in use, the driving plate 609 is driven to move forward by the extension of the cylinder 611, so that the extrusion plate 619 squeezes the driving rods 6134 on the interface tube 1 612 and the interface tube 2 613 at the same time, so that the annular piston 6133 drives the annular piston 6133 to move toward the front end of the cavity 6132, allowing the annular airbag 6131 to expand outward, thereby sealing and locking the silicone drainage tube.

[0046] Among them, a controller is provided in the control box 3, and the controller is electrically connected to the alarm light 5, the air pressure detection meter 11, the cylinder one 605, the cylinder two 611, the cylinder three 706, the cylinder four 710 and the electric telescopic rod 704.

[0047] Working principle:

[0048] When the air tightness test is performed on a plurality of silicone drainage tubes without connectors, a multi-row testing mechanism 6 is selected for testing, one end of the plurality of silicone drainage tubes is inserted into the interface tube 1 612, and the other end thereof is inserted into the corresponding interface tube 2 613, and the solenoid valve tube wall in the interface tube 1 612 that is not connected to the silicone drainage tube is moved forward by the extension of the cylinder 2 611, so that the extrusion plate 619 squeezes the driving rods 6134 on the interface tube 1 612 and the interface tube 2 613 at the same time, so that the annular piston 6133 is driven to move toward the front end of the cavity 6132, and the annular airbag 6131 is expanded outward, thereby sealing and locking the end of the silicone drainage tube; at the same time, the cylinder 1 605 is used to press the driving rods 6134 on the interface tube 1 612 and the interface tube 2 613. The elongation drives the lifting plate 602 to descend, thereby pressing the air pressure detection gauge 11 on the detection plate 606, making it sealed and connected with the detection plate 606, and the air pressure detection gauge 11 is electrically connected to the control box 3, and the detection structure is fed back; at this time, the inflation tube 616 is inflated by the inflation device, and the gas enters the silicone drainage tube and the interface tube 2 613 from the interface tube 1 612. When the gas is inflated to a certain amount, the pressure is stabilized. At this time, the air pressure detection gauge 11 detects the size of the pressure of the silicone drainage tube. If the value detected by the air pressure detection gauge 11 is consistent with the inflation pressure stabilization, the air tightness of the silicone drainage tube is good. If the value detected by the air pressure detection gauge 11 is too small, the silicone drainage tube has a gas leakage phenomenon, and the alarm light 5 sends an alarm signal. At the same time, the interior of the pool 2 10 is filled with water, and the middle part of the silicone drainage tube is located in the water. The water pool 2 10 is observed by the immersion method to see if there are bubbles. If there are bubbles, it means that the silicone drainage tube has a gas leakage phenomenon.

[0049] When testing the air tightness of a single silicone drainage tube with a connector, a single-row testing mechanism 7 is selected for testing. One end of the connector of the silicone drainage tube is stacked in the bayonet 708 of the extension plate 707. The cylinder 3 706 is extended to drive the plug 1 709 to descend to block the inner hole of the tube body. The end of the silicone drainage tube without the connector is inserted into the through hole 7021. The cylinder 4 710 is extended to insert the plug 2 711 into the end of the tube body. Then the clamp 7022 is driven down by the electric telescopic rod 704 to press and seal the silicone drainage tube. The inflation port 712 is inflated by the inflation device to detect the air pressure change in the tube body. At the same time, the interior of the pool 1 8 is filled with water, and the middle part of the silicone drainage tube is located in the water. The pool 1 8 is observed by immersion to see if there are bubbles. If there are bubbles, it means that the silicone drainage tube is leaking.

[0050] In summary, the present invention can improve the working efficiency of silicone drainage tube air tightness detection, increase the installation convenience of silicone drainage tube detection, and increase the accuracy of air tightness detection; at the same time, the equipment can detect silicone drainage tubes of different specifications and styles, thereby increasing the adaptability of the detection device.

When the driving rod (6134) moves inward, the annular piston (6133) is driven to move toward the front end of the cavity (6132), compressing the internal space of the cavity (6132), so that the annular airbag (6131) expands outward and tightly presses against the inner wall of the silicone drainage tube sleeved on the tube wall of the interface tube 1 (612) and the interface tube 2 (613), so that they are sealed and connected; A cylinder second mounting frame (617) is provided at the rear of the base plate (601), and both ends of the cylinder second mounting frame (617) are fixedly mounted on the top of the detection support frame (1), and two slide bars (618) are symmetrically mounted at both ends of the cylinder second mounting frame (617), and a slider (607) is slidably mounted on the two slide bars (618), and the rear sides of the two sliders (607) are fixedly connected by a fixing plate (610), and the front sides of the two sliders (607) are fixedly connected to the slider second (608), and the front end of the slider second (608) is slidably mounted on the slider first (603) through the slider (607); the two sliders second (608) ) is slidably provided with a driving plate (609), and two cylinders (611) are symmetrically installed on the fixed plate (610), and the movable ends of the two cylinders (611) are connected to the driving plate (609). A squeezing plate (619) is provided on the side of the driving plate (609) away from the cylinder (611). When in use, the squeezing plate (619) squeezes the driving rod (6134) on the interface tube (612) and the interface tube (613) at the same time to move, so that the annular piston (6133) moves toward the front end of the cavity (6132), allowing the annular airbag (6131) to expand outward, thereby sealing and locking the end of the silicone drainage tube.
