Detailed Description
The technical solutions of the present utility model will be clearly and completely described in connection with the embodiments, and it is obvious that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, an underwater airtight plug device with a spring comprises a cylinder 2 and a moving rod 5 connected with the telescopic end of the cylinder, wherein one end of the moving rod 5 away from the cylinder 2 is inserted into an inner sleeve 4, one end of the inner sleeve 4 away from the cylinder 2 is connected with an outer sleeve 3, an adjusting spring 6 is sleeved between the inner sleeve 4 and the bottom end of the moving rod 5 outside the moving rod 5, the upper end of the adjusting spring 6 is abutted with the bottom of the inner sleeve 4, and the lower end of the adjusting spring 6 is abutted with the bottom of the moving rod 5.
As an optimization scheme of the utility model, both sides of the inner sleeve 4 are provided with the moving grooves 9 along the length direction, the inside of the moving grooves 9 is provided with the limiting pins 8 in a sliding manner, and one end of each limiting pin 8 enters the inside of the inner sleeve 4 and is connected with the moving rod 5. When the movable rod 5 moves, the stopper pin 8 slides in the movement groove 9 to guide the movable rod 5.
As an optimization scheme of the utility model, a jack 10 is arranged at the joint of the end part of the movable rod 5 and the limiting pin 8, and one end of the limiting pin 8 is inserted into the jack 10. After the limiting pin 8 is inserted into the moving rod 5, the movement of the moving rod 5 can be guided, and the moving rod 5 is prevented from rotating.
As an optimization scheme of the utility model, the bottom end of the movable rod 5 is integrally connected with a baffle plate which is in threaded connection with the telescopic end of the air cylinder 2. The movable rod 5 is connected with the telescopic end of the air cylinder 2 through threads, so that the follow-up disassembly and maintenance are simple.
As an optimization scheme of the utility model, the inner end part of the inner sleeve 4 of the movable rod 5 is connected with a limiting plate 7, and the connecting end of the outer sleeve 3 and the inner sleeve 4 is arranged in a sealing way.

When the air tightness detecting device is used, the required number of air tightness plug devices are arranged on the base plate 1 according to the requirements of an actual detector, so that a plurality of pipelines can be detected at one time in the air tightness detecting process, and the working efficiency is improved. In the detector, the same number of airtight plug devices are arranged on the backing plates 1 at the two ends, the airtight plug devices at the two ends are mutually corresponding to be groups, and the airtight plug devices of the same group are positioned on the same straight line. The pipeline to be detected is placed between the two airtight plug devices in the same group, the end part of the pipeline is inserted into the outer sleeve 3, and the end part of the pipeline is sleeved and abutted and sealed by the outer sleeve 3, so that the pipeline is convenient to detect the air tightness in water.
