[0040] The present invention will be further described in detail below with reference to the accompanying drawings.

[0041] like Figure 1 , 2 As shown, the specific structure of the air content measuring instrument for concrete pipe foundations includes a barrel 1 and a cover 2. The structure of the cover 2 and the installed pressure gauge, valves, etc., are all existing technologies. A barrel rim 11 is provided at the upper end of the barrel 1, and a cover rim 21 is provided at the lower end of the cover 2. A fastening mechanism 3 is used to fix the cover 2 to the barrel 1, thereby sealing the barrel 1. The connection and fixation between the barrel 1 and the cover 2 is simpler and more reliable.

[0042] like Figure 3 , 4 As shown, the specific structure of the fastening mechanism 3 includes a connecting buckle 31, which has a groove for accommodating the barrel rim 11 and the cover rim 21. A stud 32 is threadedly connected to the upper end of the connecting buckle 31, and the lower end of the stud 32 can press against the upper end face of the cover rim 21. A bolt 34 is fixedly disposed on the upper end of the cover rim 21, and the connecting buckle 31 is movably sleeved on the bolt 34. The connecting buckle 31 can rotate around the bolt 34 and can also move along the axial direction of the bolt 34. During disassembly and assembly, the connecting buckle 31 is always connected to the cover 2 by the bolt 34 and will not detach from the cover 2, making it easy to operate and not easy to lose. A spring 33 is sleeved on the outer periphery of the shank of the bolt 34, and the upper and lower ends of the spring 33 abut against the head of the bolt 34 and the first connecting member 311, respectively. The spring 33 can ensure that the connecting buckle 31 can rotate around the bolt 34 and maintain a gap between the lower end of the connecting buckle 31 and the cover rim 21 for accommodating the barrel rim 11, which facilitates quick alignment and installation with the barrel 1.

When opening is needed, the upper bolt 32 is screwed in the opposite direction, the lower end of the bolt 32 is separated from the cover 2, and then the connecting buckle 31 is rotated counterclockwise around the bolt 34, so that the barrel along 11 and the cover along 21 are separated from the groove structure of the connecting buckle 31, and the cover 2 and the barrel 1 are separated.

[0044] The specific structure of the connecting buckle 31 includes a first connecting piece 311, a second connecting piece 312 and a third connecting piece 313 which are integrally formed. The outer sides of the first connecting piece 311, the second connecting piece 312 and the third connecting piece 313 are provided with reinforcing ribs, so as to further ensure the strength of the three. The first connecting piece 311 is arranged at the upper end of the cover along 21 in the horizontal direction and is movably sleeved on the bolt 34. The second connecting piece 312 is arranged at the lower end of the first connecting piece 311 in the vertical direction. The third connecting piece 313 is arranged at the lower end of the second connecting piece 312 in the horizontal direction. The first connecting piece 311 and the third connecting piece 313 are located on the same side of the second connecting piece 312. The first connecting piece 311, the second connecting piece 312 and the third connecting piece 313 are combined into a groove structure with an opening inward for accommodating the barrel along 11 and the cover along 21.

[0045] The end of the first connecting piece 311 away from the second connecting piece 312 is provided with a first connecting hole 314 and a second connecting hole 315, and the first connecting hole 314 and the second connecting hole 315 form a stepped hole.
