And when detecting instrument 5 waited to take out, can rotate interior sleeve pipe 2, perhaps rotate core pipe 3, make interior sleeve pipe 2 and core pipe 3 relative slip, second inspection hole 21 misplaces completely with third inspection hole 31, at this moment because detecting instrument 5 seals to peg graft in the instrument mounting hole, detection space is sealed, just can keep detecting instrument 5 taking out under encapsulated situation, and the poisonous in the detection space, harmful substance also sealed isolation is in the inner chamber of core pipe 3 with interior sleeve pipe 2, poisonous, harmful substance diffusion or with people direct contact have been avoided.

Of course, it can be understood that, as shown in fig. 4, when measuring the wind speed, the third detecting hole 31, the second detecting hole 21 and the first detecting hole 11 need to completely penetrate through the side walls of the core tube 3, the inner sleeve 2 and the outer sleeve 1, respectively, and the detecting end of the detecting instrument 5 also needs to be located at the position through which the air flows, so that the air can smoothly flow through the detecting instrument 5, and the wind speed in the sealed production environment can be detected more accurately; when other link parameters such as temperature, humidity and the like are detected, only the detection space needs to be exposed.

Alternatively, in some embodiments, as shown in fig. 4 and 7, the movable assembly 4 includes a connecting shaft 41 and an elastic member 42, and the elastic member 42 is sleeved outside the connecting shaft 41. Specifically, the front end of the inner sleeve 2 has a slide hole in which the connecting shaft 41 is slidably disposed. An elastic piece 42 is arranged between the front end of the connecting shaft 41 and the front end surface of the inner sleeve 2 in a clamping mode, the rear end of the connecting shaft 41 is fixedly connected to the front end of the core tube 3, and the elastic piece 42 is used for driving the core tube 3 to slide linearly relative to the inner sleeve 2.

Further, an oilless bearing (not shown in the figure) and an O-ring (not shown in the figure) are further arranged between the connecting shaft 41 and the sliding hole, so that the connecting shaft 41 can move more smoothly and is not easy to block, and the sealing performance is better.

In use, in the present embodiment, the test meter 5 is first installed into the inner tube 2 through the meter installation hole, and when the inner tube 2 is not installed into the outer tube 1, as shown in fig. 7, the spring is in an insufficiently compressed state. As the inner tube 2 slides gradually in the outer tube 1, the front end of the connecting shaft 41 abuts against the front end of the outer tube 1, and the spring is changed from the insufficiently compressed state shown in fig. 7 to the sufficiently compressed state shown in fig. 4, and at this time, the core tube 3 slides toward the rear end of the inner tube 2 relative to the inner tube 2 by the pushing of the rear end of the connecting shaft 41. When the spring is fully compressed to enable the first detection hole 11, the second detection hole 21 and the third detection hole 31 to be aligned, the core tube 3, the inner sleeve 2 and the outer sleeve 1 move to the detection state, and the detection space is communicated with the sealed production environment in the isolator or the sterile chamber sequentially through the third detection hole 31, the second detection hole 21 and the first detection hole 11. At this time, the instrument mounting apparatus can be in a stable detection state only by fixing the inner tube 2 to the outer tube 1, or to the mounting plate 9 described above, or to the side wall of the isolator or the sterile room. Optionally, in this embodiment, the rear end of the inner sleeve 2 is provided with a fixing hole (not shown in the figure), the mounting plate 9 is provided with a corresponding threaded hole (not shown in the figure), and a bolt (not shown in the figure) passes through the fixing hole and is screwed into the threaded hole, so that the inner sleeve 2 and the mounting plate 9 can be relatively fixed.

When the meter 5 is to be removed, as shown in fig. 3 and 6, the inner tube 2 and the meter 5 need to be removed from the outer tube 1. In the process of drawing out the inner sleeve 2, the spring in a fully compressed state gradually extends, so that the connecting shaft 41 is also in a motion state of "drawing out" the inner sleeve 2, and at this time, the core tube 3 also moves along with the connecting shaft 41, namely slides towards the front end direction of the inner sleeve 2 relative to the inner sleeve 2, so that the second detection hole 21 and the third detection hole 31 are gradually dislocated. When the spring recovers to the state of insufficient compression, as shown in fig. 7, the second detection hole 21 and the third detection hole 31 are completely staggered, the detection space is in a sealed state at the moment, the detection instrument 5 can be taken out in the sealed state, and the toxic and harmful substances in the detection instrument 5 are prevented from being diffused to cause personal safety risks.

The first and second magnetic members attract each other so that the angle between the core tube 3 and the outer sleeve 1 can be kept relatively fixed when the inner sleeve 2 is inserted into the outer sleeve 1. During the use, under the detection state, first inspection hole 11, second inspection hole 21 and third inspection hole 31 three align, and when instrumentation 5 waited to take out, operating personnel can hold the rotatory interior sleeve pipe 2 of the rear end of interior sleeve pipe 2, because first magnetic part and second magnetic part attract each other this moment, first inspection hole 11 and third inspection hole 31 keep the alignment state, second inspection hole 21 on interior sleeve pipe 2 then rotates to misplace completely with first inspection hole 11 and third inspection hole 31, make the lateral wall of interior sleeve pipe 2 rotate to the state of closing third inspection hole 31, and second inspection hole 21 on interior sleeve pipe 2 is by the lateral wall confined state of core pipe 3. At this moment, detection space just can be in encapsulated situation, and instrumentation 5 just also can take out under encapsulated situation, prevents that the poisonous and harmful substance in instrumentation 5 from diffusing or direct and human contact from causing the personal safety risk.

Obviously, in the present invention, the shapes of the outer sleeve 1, the inner sleeve 2 and the core tube 3 are rotated according to the relationship of movement therebetween. It will be appreciated that when there is only an axial sliding relationship between the outer sleeve 1 and the inner sleeve 2, the inner wall shape of the outer sleeve 1 and the outer wall shape of the inner sleeve 2 may adopt a corresponding circular tube shape, a square tube shape or a tube shape with a specific cross section, and when there is both an axial sliding and a relative rotation around an axis between the outer sleeve 1 and the inner sleeve 2, the inner wall shape of the outer sleeve 1 and the outer wall shape of the inner sleeve 2 preferably adopt a corresponding circular tube shape. Similarly, when there is only an axial sliding relationship between the core tube 3 and the inner sleeve 2, the inner wall shape of the inner sleeve 2 and the outer wall shape of the core tube 3 may take a corresponding circular tubular shape, a square tubular shape, or a tubular shape of a specific cross section, and when there is both axial sliding and relative rotation about an axis between the core tube 3 and the inner sleeve 2, the inner wall shape of the inner sleeve 2 and the outer wall shape of the core tube 3 preferably take a corresponding circular tubular shape.

Therefore, in the present invention, the shapes of the outer tube 1, the inner tube 2, and the core tube 3 are not particularly limited, and it is sufficient if the movement relationship between each other is satisfied and it is also possible to ensure that no leakage occurs between the outer tube 1, the inner tube 2, and between the inner tube 2 and the core tube 3. Alternatively, in the above embodiment, when there is only an axial sliding relationship between the outer sleeve 1, the inner sleeve 2 and the core tube 3, a square tube is adopted, which further facilitates the alignment of the first detecting hole 11, the second detecting hole 21 and the third detecting hole 31.

Optionally, as shown in fig. 2, 5 and 8, the meter mounting device further comprises a cover 8, wherein the cover 8 is movably arranged outside the outer sleeve 1. This closing cap 8 is used for sealing first inspection hole 11, can enough be when wasing the isolator inside, seal first inspection hole 11 through closing cap 8, prevent the contact of instrumentation 5 and washing liquid in the detection space, conveniently wash with the purified water and drench, wash the poisonous of outer tube 1 outside, harmful substance, and when needs take out instrumentation 5, as shown in fig. 6 and fig. 7, can also seal first inspection hole 11 through closing cap 8 earlier, sleeve pipe 2 makes the mode of second inspection hole 21 and third inspection hole 31 dislocation in the operation again, prevent behind sleeve pipe 2 in taking out, sealed production environment in isolator or the aseptic chamber directly communicates with the external world through this instrument installation device, produce the risk of revealing. Optionally, the sealing cover 8 is fixedly connected to the outer side of the outer sleeve 1 by means of sliding sleeves, screw connections or rotating hinges, and is simple in structure and easy to maintain.

Alternatively, as shown in fig. 4 and 7, a first sealing member 71 is disposed at the first detection hole 11 on the outer sleeve 1, and the first sealing member 71 can be interposed between the outer sleeve 1 and the cover 8. In this embodiment, two sealing rings are used as the first sealing member 71, and the two sealing rings are respectively disposed on two sides of the first detecting hole 11, and when the first detecting hole 11 is closed by using the above-mentioned cover 8, the two sealing rings abut between the outer sleeve 1 and the cover 8, so that the first detecting hole 11 can be better sealed, and the substance in the isolator or the sterile chamber can be prevented from entering the meter installation device through the first detecting hole 11.

Further, as shown in fig. 3, 6 and 9, a first air filter 61 is provided at the front end of the inner tube 2, and a second air filter 62 is provided at the rear end of the inner tube 2. When the sealing cover 8 seals the first detection hole 11 and the inner sleeve 2 needs to slide out of the outer sleeve 1, air enters the detection space through the second air filter 62 and flows out between the inner sleeve 2 and the outer sleeve 1 through the first air filter 61, so that negative pressure cannot be generated between the inner sleeve 2 and the outer sleeve 1 due to sliding, and the inner sleeve 2 cannot or is difficult to slide out of the outer sleeve 1; similarly, when the inner sleeve 2 slides into the outer sleeve 1, as shown in fig. 9 and 6, a part of air between the inner sleeve 2 and the outer sleeve 1 is compressed, enters the detection space from the first air filter 61, and then flows out through the second air filter 62, so that the sliding of the inner sleeve 2 into the outer sleeve 1 is facilitated, and simultaneously, the leakage of substances in the sealed production environment in the isolator or sterile room to the outside through the instrument mounting device is prevented.

It is particularly emphasized that in the present invention, the gas-tight sliding between the inner sleeve 2 and the outer sleeve 1 is not absolutely gas-tight, but depends on the actual production requirements. For example, when the actual production requirement only requires that a large amount of outside air be prevented from entering the isolator or the sealed space to contaminate the internal sealed production environment, or that a large amount of substances in the sealed production environment flow out to contaminate the outside, it is only necessary to control the shape tolerance of the two, so that the inner sleeve 2 and the outer sleeve 1 can still move relative to each other even without installing the first air filter 61 and the second air filter 62; when the actual production requirement requires high air tightness, for example, when the first sealing member 71 is provided, the first air filter 61 and the second air filter 62 are required to be provided to prevent the inner sleeve 2 from sliding out of the outer sleeve 1 due to the negative pressure generated between the inner sleeve 2 and the outer sleeve 1 during sliding.

Alternatively, as shown in fig. 4 and 7, a third sealing member 73 may be provided at the third detection hole 31 in the core tube 3, and the third sealing member 73 may be interposed between the inner tube 2 and the core tube 3. In the present embodiment, two sealing rings are used as the third sealing member 73, which are sleeved around the core tube 3, and when the third inspection hole 31 and the second inspection hole 21 are completely misaligned, the two sealing rings are positioned on both sides of the second inspection hole 21 and abut against the core tube 3 and the inner tube 2, thereby preventing the leakage between the core tube 3 and the inner tube 2.

Alternatively, as shown in fig. 4 and 7, the inner tube 2 is provided with a fourth seal 74, the fourth seal 74 is provided corresponding to the first detection hole 11, and the fourth seal 74 can be interposed between the inner tube 2 and the outer tube 1. Illustratively, in the present embodiment, the fourth sealing element 74 is two sealing rings sleeved on the inner sleeve 2, and when the first detection hole 11 is completely misaligned with the second detection hole 21, the two sealing rings are located at two sides of the first detection hole 11 and abut between the outer sleeve 1 and the inner sleeve 2, so that a substance in a sealed production environment in an isolator or a sterile room can be prevented from entering between the outer sleeve 1 and the inner sleeve 2 through the first detection hole 11 during the sliding process of the inner sleeve 2 relative to the outer sleeve 1. Preferably, when the second sealing element 72 and the fourth sealing element 74 are needed to be arranged at the same time, three sealing rings are arranged outside the inner sleeve 2, and the middle sealing ring can form the second sealing element 72 together with the rear sealing ring and can form the fourth sealing element 74 together with the front sealing ring, so that the structure is simpler and the cost is lower.

Of course, in the above-described embodiment, the first seal 71, the second seal 72, the third seal 73, the fourth seal 74, and other seals may be provided in other forms, for example, a seal ring may be laid on the side wall, and the seal ring may be concentric with the inspection hole, thereby achieving a sealing effect. Therefore the utility model discloses in, do not specifically prescribe a limit to the structure and the constitution of each sealing member, as long as can play corresponding sealed effect can.
