Description

Technical Field

[0001] The utility model relates to the field of down processing, in particular to a down air tightness detection device. Background Art

[0002] Before using down for textiles, the elasticity of the down needs to be tested, and the staff needs to test the air tightness of the down to evaluate the quality of the down. The error needs to be reduced during the test so that the air tightness of the down can be accurately reflected after the test.

[0003] Since the down content has a significant impact on air tightness, current detection devices are not convenient for visually displaying the air tightness of down during testing, which results in low detection efficiency. In addition, it is not convenient for accurately displaying the leakage amount during testing, which leads to large errors and poor detection results. Utility Model Content

[0004] In order to overcome the above shortcomings, the utility model provides a down air tightness detection device, which can intuitively show the air tightness of the down by observing bubbles, and can accurately display the leakage amount to enhance the detection effect.

[0005] The technical solution of the utility model is: a down air tightness detection device, including a test cylinder, a piston plate is slidably connected to the inside of the test cylinder, a connecting rod is fixedly connected to the piston plate, the connecting rod passes through the test cylinder, two water inlet pipes are fixedly connected to the test cylinder, both of the water inlet pipes are provided with valves, a placement groove is opened on the test cylinder, a material clamping assembly is provided on the test cylinder, and an indicator assembly is provided on the test cylinder, the material clamping assembly is used to clamp down, and the indicator assembly is used to indicate the leakage amount.

[0006] As a preferred technical solution of the present invention, the testing tube is made of transparent material.

[0007] As a preferred technical solution of the present invention, the material clamping assembly includes a frame, two of the frames are slidably connected to the placement groove, fixed nets are fixedly connected to the two frames, and sealing strips are provided on the frames.

[0008] As a preferred technical solution of the present invention, the indicating assembly includes a sliding rod, which is slidably connected to the test cylinder. A sliding piece is fixedly connected to the bottom of the sliding rod, and a compression spring is provided between the sliding piece and the test cylinder.

[0009] As a preferred technical solution of the present invention, the sliding rod is provided with a scale.

[0010] Compared with the existing technology, the utility model has the following advantages: 1. The movement of the connecting rod will drive the movement of the piston plate, and the movement of the piston plate will reduce the space in the lower layer of the test cylinder. The water will compress the air in the lower layer to increase the air pressure. If the air tightness of the down is poor, the air in the lower layer will pass through the down and generate bubbles in the upper water layer, thereby better displaying the air tightness of the down, making the detection more convenient, and thus improving the detection efficiency.

[0011] 2. The increase of air in the upper layer will increase the air pressure. The increase of air pressure will squeeze the sliding piece to move. The movement of the sliding piece drives the sliding rod to move upward, and the compression spring is compressed. The staff can calculate the leakage rate of down under a certain pressure according to the scale on the sliding rod. The down can be evaluated according to the leakage rate of the down, and then the leakage rate of the down can be accurately displayed, thereby more accurately detecting the air tightness of the down, thereby enhancing the detection effect.

DETAILED DESCRIPTION

[0018] First of all, it should be noted that in the various embodiments described, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.

[0019] Example 1: A down air tightness detection device, such as Figure 1-Figure 5As shown, it includes a test cylinder 1, a piston plate 2 is slidably connected to the inside of the test cylinder 1, a connecting rod 21 is welded to the piston plate 2, and the connecting rod 21 passes through the test cylinder 1, two water inlet pipes 3 are welded to the test cylinder 1, and both water inlet pipes 3 are provided with a valve 4, a placement groove 5 is opened on the test cylinder 1, and the placement groove 5 is used to place down, the test cylinder 1 is provided with a clamping assembly, and the test cylinder 1 is provided with an indicator assembly, the clamping assembly is used to clamp the down, and the indicator assembly is used to indicate the leakage amount.

[0020] The test tube 1 is made of a transparent material, and the transparent test tube 1 is used for easy observation.

[0021] The clamping assembly includes a frame 6, and the two frames 6 are slidably connected to the placement groove 5. The two frames 6 are fixedly connected to a fixed net 7. The frame 6 is provided with a sealing strip 8, and the sealing strip 8 is used to prevent air leakage.

[0022] The indicating assembly includes a sliding rod 9, which is slidably connected to the test cylinder 1 and is used to indicate air leakage. A sliding piece 10 is fixedly connected to the bottom of the sliding rod 9, and a compression spring 11 is provided between the sliding piece 10 and the test cylinder 1.

[0023] The sliding rod 9 is provided with a scale, and the scale on the sliding rod 9 is used to display the leakage amount.

[0024] When it is necessary to test the air tightness of down, the staff first evenly spreads the down between the two frames 6, then inserts the frames 6 into the placement slot 5, then opens the valve 4 and injects a certain amount of water into the upper and lower layers of the test cylinder 1 at the same time, closes the valve 4, and then pushes the connecting rod 21. The movement of the connecting rod 21 will drive the piston plate 2 to move. The movement of the piston plate 2 will shrink the space in the lower layer of the test cylinder 1, and the water will compress the air in the lower layer to increase the air pressure. If the air tightness of the down is poor, the air in the lower layer will pass through the down and generate bubbles in the upper water, thereby better showing the air tightness of the down, making the test more convenient, thereby improving the test efficiency, and the bubbles generated will float upwards. The water in the down jacket is mixed with the upper air. After a period of time, the increase in the upper air will increase the air pressure. The increase in air pressure will squeeze the sliding piece 10 to move. The movement of the sliding piece 10 drives the sliding rod 9 to move upward, and the compression spring 11 is compressed. The staff can obtain the leakage rate of the down under a certain pressure according to the scale on the sliding rod 9. The down can be evaluated according to the leakage rate of the down, and the leakage rate of the down can be accurately displayed, so as to more accurately detect the air tightness of the down, thereby enhancing the detection effect. After the detection is completed, the frame 6 is removed, the water in the upper layer falls to the bottom, the pressure returns to normal, the compression spring 11 is reset, and the sliding piece 10 and the sliding rod 9 are reset, and the down can be taken out.

[0025] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
