Technical Field

[0001] The utility model relates to the technical field of nylon tube detection, in particular to a nylon tube leakage testing device. Background Art

[0002] Nylon tube is a synthetic fiber with good physical, chemical and mechanical properties. Compared with ordinary copper tubes, steel tubes and rubber tubes, nylon tubes have great stability in wear resistance, tensile and bending properties, and are easy to install without the use of any special tools. Therefore, they are widely used in various industries such as instrument lines, irrigation control systems, textile mills, and electrostatic insulators. In current life, nylon tubes need to be connected with connectors after production, and then the nylon tubes are tested for air tightness.

The device is provided with a first sealing sleeve, a second sealing sleeve, a connector, an air intake pipe, a first mounting block, a second mounting block, an air pressure sensor, and a control panel. After one end of the nylon tube is plugged into the connector, the second sealing sleeve is rotated upward until the first mounting block and the second mounting block are engaged and fixed. Air is then ventilated into the air intake pipe, and the air pressure sensor is used for detection. The detection data is displayed on the control panel. In this way, the airtightness of the nylon tube after plugging can be accurately measured to ensure the accuracy of the test results. At the same time, the nylon tube can be directly stored after the test is completed, which is very convenient. However, the patent still has the following problems in actual use:

However, the semicircular splint of the device cannot meet the effect of limit detection of nylon tubes of various specifications, thereby greatly reducing the scope of application of the device and bringing limitations to the staff when using it.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a nylon tube leakage test device, comprising a first sealing sleeve and a second sealing sleeve, wherein the first sealing sleeve and the second sealing sleeve are rotatably connected to each other, a connecting shell is installed on the inner side of the first sealing sleeve, and an air pressure sensor is installed on the inner side of the second sealing sleeve; an adjustment mechanism is provided on the inner side of the connecting shell, and a connecting assembly is provided between the first sealing sleeve and the second sealing sleeve;

[0008] Among them, the adjustment mechanism includes a support frame installed on the inner side of the connecting shell, and sliding boxes are symmetrically installed inside the two ends of the support frame, and the sliding box is rotatably connected to the inside of the bidirectional screw, and the two ends of the bidirectional screw are symmetrically threaded on the outside with a moving sleeve, and an arc plate is provided on one side of the moving sleeve, and a rubber pad is installed on one side of the arc plate, and a rotating wheel is installed at the bottom end of the bidirectional screw, and a belt is sleeved between the outer sides of the rotating wheels.

[0009] Preferably, the connecting assembly includes a fixed box symmetrically installed on one side of the first sealing sleeve, and a plug-in plate is symmetrically installed on one side of the second sealing sleeve, and the plug-in plate and the fixed box are plugged in, and a clamping seat is installed on the inner side of the fixed box, and the inner side of the fixed box is symmetrically rotatably connected with a movable plate, and both ends of the clamping seat are symmetrically rotatably connected with movable rods, and one end of the movable rod is rotatably connected to the movable plate, and one end of the movable plate is installed with an plug-in block, and the plug-in block is plugged in to the plug-in plate, and a fixing knob is internally threaded on one side of the fixed box.

[0010] Preferably, sliding grooves are symmetrically provided inside both ends of the support frame, and sliders are slidably connected inside the sliding grooves, and the sliders are fixedly connected to the movable sleeve and the arc-shaped plate.

[0014] Preferably, one end of the plug board is plugged into the card seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the nylon tube leakage test device is specifically designed as follows: the rotation of the bidirectional screw is driven by rotating the rotating rod, and the two sets of bidirectional screws are driven to rotate through the cooperation between the rotating wheel and the belt. The rotation of the bidirectional screw drives the movable sleeve to slide inside the sliding box, thereby driving the arc plates to move closer to and away from each other. At this time, the rubber pad is squeezed and fixed to the outside of the nylon tube. At this time, the rubber pad is squeezed and deformed, thereby achieving the effect of rapid fixed detection of nylon tubes of various specifications, which can greatly improve the detection range of the device and improve the practicality of the device when used. The inside of the box allows the plug-in plate to be plugged into the card seat. At this time, the movement of the card seat drives the movement of the movable rod, and the movement of the movable rod pulls the movable plate to rotate, so that the two sets of plug-ins can be plugged into the plug-in plates. The staff then turns the fixing knob to squeeze and limit the plug-in plates, so that the first sealing sleeve and the second sealing sleeve can be quickly docked and fixed. The dual fixing method of the plug-in block and the fixing knob can make the first sealing sleeve and the second sealing sleeve more stable when closed, avoiding the phenomenon of gap or separation between the first sealing sleeve and the second sealing sleeve caused by external force factors, thereby further improving the nylon tube detection efficiency.

[0016] 1. Insert the nylon tube into the connecting shell, and the nylon tube and the air inlet pipe fit tightly together. Then, the rotating rod drives the rotation of the bidirectional screw, and the rotation of the bidirectional screw drives the rotation of the runner. The runner cooperates with the belt to drive the rotation of the two sets of bidirectional screws. The rotation of the bidirectional screw drives the movable sleeve to slide inside the sliding box. At this time, the movable sleeve moves in a gathering and expanding trajectory, so that the slider can slide inside the slide groove, thereby driving the arc plates to move closer and farther away from each other. At this time, the rubber pad is squeezed and fixed to the outside of the nylon tube. At this time, the rubber pad is squeezed and deformed, so that various specifications of nylon can be realized. The effect of the dragon tube in performing rapid fixed detection can greatly improve the detection range of the device and improve the practicality of the device when in use. By rotating and closing the first sealing sleeve and the second sealing sleeve, the semicircular rubber block is squeezed and fitted between the nylon tube and the intake pipe, so that the semicircular rubber block is in a ring shape as a whole. In addition, the plasticity of the semicircular rubber block can be used to squeeze and deform nylon tubes of various specifications, thereby improving applicability and effectively avoiding deviations in the air pressure sensor during airtightness detection of the connection between the nylon tube and the intake pipe, thereby greatly improving the detection accuracy of the device and bringing convenience to the staff when in use.

[0017] 2. When the first sealing sleeve and the second sealing sleeve are rotated and closed, the plug plate is inserted into the fixed box, so that the plug plate and the card seat are plugged in. At this time, the plug plate drives the card seat to move. At this time, the movement of the card seat drives the movement of the movable rod. The movement of the movable rod pulls the movable plate to rotate, so that the two sets of plug blocks and the plug plate can be plugged in. The staff then turns the fixing knob to squeeze and limit the plug plate, so that the first sealing sleeve and the second sealing sleeve can be quickly docked and fixed. The dual fixation of the plug block and the fixing knob can make the first sealing sleeve and the second sealing sleeve more stable when closed, avoiding the phenomenon of gap or separation between the first sealing sleeve and the second sealing sleeve caused by external force factors, thereby further improving the nylon tube detection efficiency.
