Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to an airtightness testing device for industrial production. Background Technology

[0002] The prior art with announcement number CN219714645U works as follows: When it is necessary to test the airtightness of welded pipe components, the pipe component is first placed between arc-shaped clamps No. 1 and No. 2, with the welded end close to the water tank. Then, cylinder No. 2 drives the connecting plate to move arc-shaped clamps No. 2 closer to arc-shaped clamps No. 1, clamping and fixing the pipe component. Then, a motor drives a screw to rotate, causing the drive plate to extend the air inlet pipe into the top end of the pipe component until the rubber sealing gasket covers and seals the top of the pipe component. At the same time, cylinder No. 1 moves the water tank upward, so that the welded part at the bottom of the pipe component is below the water surface. Then, the air compressor is started, and the air inlet pipe inputs gas into the pipe component. The airtightness of the pipe component is tested by observing whether bubbles are generated on the water surface. The solenoid valve can be controlled to open the corresponding number of air inlet pipes for the number of pipe components tested at one time. The drain outlet facilitates the periodic replacement of water in the water tank to avoid turbid water affecting the clarity of bubble observation.

[0003] It is easy to see that it is difficult to inspect pipe fittings of different diameters and different lengths at the same time, which leads to its limited inspection capabilities. Utility Model Content

[0004] The purpose of this invention is to provide an airtightness testing device for industrial production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an airtightness testing device for industrial production, comprising a mounting frame and a testing component slidably mounted on the mounting frame; the testing component includes a support frame, one end of which is movably connected to a bottom cover, and the other end of which is provided with a support base; the support base is also provided with an upper cover, and the upper cover is connected to a nut by a screw passing through the support base, and the upper cover is moved on the support frame by rotating the nut; the screw has a connecting hole, and an external air source is introduced into the component through the connecting hole.

[0006] As a preferred technical solution of this utility model: the support frame is slidably engaged with the mounting frame through a slider.

[0007] As a preferred technical solution of this utility model: both the upper cover and the bottom cover are provided with rubber pads on the side facing the pipe.

[0008] As a preferred technical solution of this utility model: after the screw passes through the nut, an air intake component is also provided; the air intake component includes a first connecting part that connects to an external air pipe and a second connecting part that is threadedly connected to the connecting hole.

[0009] As a preferred technical solution of this utility model: the first connecting part is further provided with a mounting base, and a pressure gauge is installed on the mounting base.

[0010] As a preferred technical solution of this utility model: the first connecting part is connected to an external air pipe through a one-way valve, and the second connecting part is provided with a polygonal prism.

[0011] The beneficial effects of this utility model by adopting the above technical solution are: 1. Since both the bottom cover and the top cover are movably mounted on the support frame, the bottom cover and the top cover corresponding to the diameter of the pipe can be replaced at the same time so that pipes of different diameters can be installed on the test piece;

[0012] 2. Since the testing components are slidably mounted on the mounting frame, it is easy to assemble multiple testing components onto the mounting frame. At the same time, the testing components are independent of each other, so different pipe diameters and different lengths of pipe fittings can be installed on each testing component. Therefore, the equipment can adapt to many different types of pipe fittings at the same time, thereby improving the testing capability of the equipment. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0019] Please see Figure 1-4 This utility model provides an embodiment of an airtightness testing device for industrial production, comprising a mounting frame 1 and a testing component 3 slidably mounted on the mounting frame 1; the testing component 3 includes a support frame 30, one end of which is movably connected to a bottom cover 35, and the other end of which is provided with a support base 33; the support base 33 is also provided with an upper cover 37, and the upper cover 37 is connected to a nut 32 after passing through the support base 33 by a screw 34, and the upper cover 37 is moved on the support frame 30 by rotating the nut 32; the screw 34 is provided with a connecting hole 314, and an external air source is introduced into the pipe 2 through the connecting hole 314.

[0020] In summary, since both the bottom cover 35 and the top cover 37 are movably mounted on the support frame 30, the bottom cover 35 and the top cover 37, which correspond to the diameter of the pipe fitting 2, can be replaced simultaneously so that pipe fittings 2 of different diameters can be installed on the test piece 3; wherein, the installation method of the bottom cover 35 and the support frame 30 is the same as that of the top cover 37.

[0021] At the same time, since the test piece 3 is slidably mounted on the mounting frame 1, it is easy to assemble multiple test pieces 3 onto the mounting frame 1. Since the test pieces 3 are independent of each other, different diameter pipe fittings 2 and different length pipe fittings 2 can be installed on each test piece 3. Therefore, the equipment can adapt to multiple different types of pipe fittings 2 at the same time, thereby improving the equipment's testing capability.

[0022] Furthermore, since the support frame 30 is slidably engaged with the mounting frame 1 via the provided slider 36, the installation of the detection element 3 and the mounting frame 1 is simple and convenient, and the distance between two adjacent detection elements 3 can also be adjusted by moving the detection element 3 on the mounting frame 1.

[0023] Meanwhile, since both the upper cover 37 and the bottom cover 35 are provided with rubber pads on the side facing the pipe 2, the two ends of the pipe 2 are reliably sealed under the action of the rubber pads, and the rubber pads can also reduce the problem of damage to the end face of the pipe 2.

[0024] Based on the above scheme, after the screw 34 passes through the nut 32, an air intake assembly 31 is also provided; the air intake assembly 31 includes a first connecting part 38 that connects to the external air pipe and a second connecting part 313 that is threadedly connected to the connecting hole 314; in specific installation, the upper cover 37 is first pressed firmly onto the pipe 2, and then the air intake assembly 31 is installed on the connecting hole 314, which facilitates the installation and replacement of the upper cover 37.

[0025] Furthermore, the first connecting part 38 is also provided with a mounting base 39, and a pressure gauge 310 is installed on the mounting base 39. Therefore, when inflating, the pressure inside the pipe fitting 2 can be monitored in real time through the pressure gauge 310; after inflation, the change in the value on the pressure gauge 310 can be used to determine whether there is a leak in the pipe fitting 2. Thus, this device can detect the pipe fitting 2 with just one pressure gauge 310, and can also improve the accuracy of the detection. In addition, since the pressure gauge 310 is movably mounted on the mounting base 39, the corresponding pressure gauge 310 can be replaced according to the detection pressure required for the pipe fitting 2.

[0026] Furthermore, since the first connecting part 38 is connected to the external air pipe via a one-way valve 311, when the internal air pressure of the pipe 2 reaches the standard, the one-way valve 311 can be pulled out and then connected to the one-way valve 311 on another detection element 3, and so on. Therefore, multiple detection elements 3 can share a single air pipe, thereby reducing the number of pipes and making it easier for users to use and operate. In addition, since the second connecting part 313 is provided with a polygonal prism 312, it is convenient for users to connect the second connecting part 313 into the connecting hole 314 by using a wrench to connect the polygonal prism 312.

[0027] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
