Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air tightness detection tools, in particular to a sealing piece for air tightness detection. Background Art
[0002] Air tightness testing is an important means to ensure product airtightness and safety. It is widely used in various industries. Airtight plugging parts are key components used to ensure the airtightness of pipes, containers or other equipment connections. The main purpose of these plugging parts is to prevent gas or liquid leakage and ensure the normal operation and safety of the system.
[0003] The current airtight sealing parts can seal the sealing parts on both sides of the test object, but the height of the existing sealing parts is mostly fixed. When the sealing parts on both sides of some test objects have different heights, it is inconvenient to adjust the height of the sealing parts to adapt. If the height of the sealing part does not match the sealing part of the test object, a tight fit cannot be achieved, resulting in reduced airtightness and possible gas or liquid leakage, affecting the accuracy of the test results. When the sealing part does not match the sealing part of the test object in height, the staff may need to use additional tools or methods to adjust the height of the sealing part, which increases the complexity and difficulty of the operation.

[0025] The motor 32 and the cylinder 9 in this technical solution are both waterproof.
[0026] Working principle: When the staff needs to perform an air-tightness test on the inspection object, the staff first places the inspection object on the top of the placing support 10, and controls the cylinder 9 to make the placing support 10 lift the inspection object and move it to the vicinity of the blocking block body 8. Then the staff rotates the knobs 54 on both sides, so that the fixed blocks 7 on the left and right sides move in the up and down directions. The staff moves the blocking block bodies 8 on both sides to the corresponding height according to the height of the blocking positions on both sides of the inspection object. After the adjustment is completed, the staff can turn on the motor 32, so that the fixed blocks 7 on both sides move toward each other. The blocking block body 8 contacts the blocking points at both ends of the inspection object to seal the inspection object. Then the cylinder 9 controls the placing support 10 to fall to its original position, and the staff can start the air-tightness test operation on the inspection object.
