Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, specifically a sealing connector for an airtightness testing instrument. Background Technology

[0002] Air tightness testing is a specialized detection technology for whether gas leaks exist in closed systems (such as containers, pipelines, and equipment). Its core purpose is to scientifically determine whether the system's sealing performance meets design or usage requirements, thus preventing safety hazards, performance degradation, or resource waste caused by leaks. The core principle of air tightness testing is based on the laws of gas flow: when a leak exists in a closed system, gas will flow through the leak point under the influence of a pressure difference (the difference between the internal pressure of the system and the external environment pressure). The detection technology detects leaks by capturing the physical changes caused by this flow.

[0003] The sealing structure is an important structural component in the sealing performance testing process. The sealing effect of the sealing structure directly affects the accuracy and repeatability of the sealing performance test. Due to the diversity of product structures and the special nature of their use, various sealing methods and structures have emerged. In actual production processes, due to the limitations of production space, the sealing structure should have the characteristics of simple operation and convenient position adjustment.

[0004] To address this issue, we propose a sealing connector for an airtightness testing instrument. Utility Model Content

[0008] Preferably, the drive assembly includes a servo motor, the output end of which is provided with a ball screw, and the end of the ball screw is connected to a sliding column, with the sealing plug threadedly installed at the end of the sliding column.

[0009] Preferably, a limiting sleeve is fixedly installed on the upper left side of the mounting plate, and the sliding column is movably installed in the middle of the inner side of the limiting sleeve.

[0019] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0020] Example: Refer to Figure 1 - Figure 3As shown, a sealing connector for an airtightness tester in this embodiment includes a fixed base plate 1, and an mounting plate 2 is provided at the upper middle part of the fixed base plate 1. The mounting plate 2 is movably installed at the upper middle part of the fixed base plate 1 and is limited and locked by fixing bolts 5.

[0021] A sealing plug 11 is provided at the upper middle part of the mounting plate 2. The sealing plug 11 is driven by the drive assembly to slide horizontally.

[0022] The clamping assembly is located at the middle of the right end of the sealing plug 11. The clamping assembly includes two sets of clamping blocks 12, which are located at both ends of the sealing plug 11. A cylinder 13 is provided on the back of the clamping block 12. The cylinder 13 is fixedly installed on the upper surface of the mounting plate 2. The two sets of cylinders 13 are driven synchronously to make the two sets of clamping blocks 12 open and close. When the two sets of clamping blocks 12 are combined, the product to be tested is clamped and fixed, thereby enhancing the stability of the sealing plug 11 inserted into the air hole of the product to be tested.

[0023] In some examples, the drive assembly includes a servo motor 7, the output end of which is provided with a ball screw 8, the end of which is connected to a sliding column 9, a sealing plug 11 is threaded onto the end of the sliding column 9, a limit sleeve 10 is fixedly installed on the upper left side of the mounting plate 2, and the sliding column 9 is movably installed in the middle of the inner side of the limit sleeve 10.

[0024] In this process, the servo motor 7 is started to drive the ball screw 8 to rotate, and then the limiting sleeve 10 limits the movement of the sliding column 9 to drive the sealing plug 11 to slide horizontally, thereby inserting the sealing plug 11 into the air hole of the product to be tested, or pulling it out of the air hole.

[0025] In some examples, the upper sides of the fixed base plate 1 are fixedly installed with limit slide rails 3, and the lower sides of the mounting plate 2 are provided with two sets of limit sliders 4. The limit sliders 4 are slidably installed on the limit slide rails 3. By sliding the limit sliders 4 on the limit slide rails 3, the position of the mounting plate 2 and the position of the sealing plug 11 can be moved and adjusted.

[0026] In some examples, the fixing bolt 5 is threaded onto the limiting slider 4 located on the left side. By tightening the fixing bolt 5, the limiting slider 4 is locked, thereby locking the position of the mounting plate 2. Conversely, by loosening the fixing bolt 5, the operator can easily push the mounting plate 2 to move it, allowing the sealing plug 11 to be moved to the product to be tested for use.

[0027] In some examples, a knob 6 is provided on the top of the fixing bolt 5, which allows the operator to rotate the fixing bolt 5 by turning the knob 6, thereby tightening or loosening the fixing bolt 5.

[0028] The working principle of this utility model is as follows:

[0029] During use, the operator first loosens the fixing bolt 5, and then pushes the mounting plate 2 to slide horizontally, thereby moving the sealing plug 11 and the clamping assembly to the pipe to be sealed. After the position is adjusted, the operator needs to rotate the knob turntable 6 to drive the fixing bolt 5 to rotate, thereby limiting and locking the position of the limit slider 4, thus locking the position of the mounting plate 2.

[0030] Then, the cylinders 13 on both sides are started. The two sets of cylinders 13 start synchronously, which pushes the two sets of clamping blocks 12 towards the center point. The two sets of clamping blocks 12 perform a closing motion, thereby clamping and fixing the pipe fitting to be sealed. At this time, the servo motor 7 starts, driving the ball screw 8 to rotate, which drives the sliding column 9 to slide horizontally, thereby pushing the sealing plug 11 into the opening of the pipe fitting to be sealed, forming a sealing blockage.

[0031] The present invention features a limiting slider 4 and a limiting slide rail 3, which facilitates the movement and adjustment of the position of the sealing plug 11 by the operator, thereby effectively improving the versatility of its application scenarios. In addition, the clamping component allows the product to be tested to be clamped and fixed, and then sealed and plugged by the sealing plug 11, thereby effectively improving the stability of the sealing and plugging and enhancing the accuracy of the airtightness test.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
