DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are indicated by the same reference numerals.

[0029] like Figure 1-5As shown, a portable sterile sampling room includes an inner support frame 1, and the inner support frame 1 includes an upper frame 2, a lower frame 3 and a first telescopic rod 4. The upper frame 2 and the lower frame 3 are interconnected by the first telescopic rod 4. The upper frame 2 and the lower frame 3 both include a connecting piece 5 and a plurality of second telescopic rods 6. The ends of the plurality of second telescopic rods 6 are interconnected by the connecting piece 5 to form a frame structure. In the present embodiment, the frame structure is specifically a quadrilateral. In other embodiments, the frame structure may also be other polygonal or irregular shapes, wherein the rectangular structure corresponding to the upper frame 2 is less than or equal to the rectangular structure corresponding to the lower frame 3 to ensure the overall support stability of the inner support frame 1, and the height position of the upper frame 2 relative to the lower frame 3 is adjustable.

[0030] Preferably, it further comprises an outer shell 7 , which is sleeved with the inner support frame 1 and supported by the inner support frame 1 , and a sampling space 8 is formed in the outer shell 7 , and an entrance 9 and a window 10 are respectively provided on the outer shell 7 .

[0031] When in use, the operator selects an outer sleeve 7 of a suitable size according to the site environment, and further moves the inner support frame 1 into the outer sleeve 7. In the initial state, the upper frame 2 and the lower frame 3 are aligned parallel to each other. At this time, the inner support frame 1 is in a storage state. When support is needed, the upper frame 2 is pulled up, and the first telescopic rod 4 is extended, so that the upper frame 2 is moved away from the lower frame 3, and the upper frame 2, the first telescopic rod 4 and the lower frame 3 form a three-dimensional support structure to complete the support of the outer sleeve 7. According to the shape of the outer sleeve 7, a suitable number of second telescopic rods 6 can be selected, and the second telescopic rods 6 can be connected and extended to each other to meet the support requirements of outer sleeves 7 of different shapes.

[0032] Preferably, the connecting member 5 includes a main body, one end of which is hinged with a first hinged arm 11 , and the first hinged arm 11 is connected to the first telescopic rod 4 so that the first telescopic rod 4 can swing in the height direction.

[0033] The swing of the first hinged arm 11 can adapt to the adjustment of the sizes of the upper frame 2 and the lower frame 3, thereby improving its application range.

[0034] Preferably, two second hinged arms 12 are hinged at one end of the main body away from the first hinged arm 11, and the two second hinged arms 12 are used to connect the second telescopic rod 6 so that the second telescopic rod 6 can swing in the horizontal direction. A hinge part 13 is formed at the lower end of the main body, and the two second hinged arms 12 both include a connecting part 14. The two connecting parts 14 are hinged to the hinge part 13 and make the two second hinged arms 12 in the same horizontal plane. The same horizontal plane can ensure the supporting effect on the outer sleeve 7 to avoid the formation of a misaligned gap between the second telescopic rod 6 and the outer sleeve 7 caused by the mutual misalignment of the two second hinge parts 13.

[0035] When in use, the relative angle of the two adjacent second telescopic rods 6 can be adjusted by swinging the two second hinged rods, thereby completing the adjustment of the frame structure. At the same time, the overall size of the inner support frame 1 can be adjusted by coordinating the swing of the first hinged rod and the extension of the first telescopic rod 4.

[0036] Preferably, in order to reduce the overall volume of the main body, the two connecting parts 14 are staggered in the horizontal direction and overlap in the height direction, so that the two connecting parts 14 are hinged to one hinge part 13.

[0037] Specifically, the first telescopic rod 4 and the first articulated arm 11 are plugged into each other, and the second telescopic rod 6 and the second articulated arm 12 are plugged into each other.

[0038] Preferably, the first telescopic rod 4 and the second telescopic rod 6 both include a first rod 15 and a second rod 16. The first rod 15 is provided with a socket 17 for the second rod 16 to be plugged in. A positioning block 18 is provided in the socket 17. The second rod 16 is provided with a groove 20 corresponding to the positioning block 18. The positioning block 18 slides with the groove 20 to limit the second rod 16 to move only along the axis direction of the first rod 15, that is, to limit the second rod 16 from rotating relative to the first rod 15. The outer wall of the first rod 15 is provided with a positioning hole 1 9, there are multiple positioning holes 19 and they are arranged along the axial direction of the first rod 15, a positioning piece is provided at the end of the second rod 16, the positioning piece is arranged corresponding to the positioning hole 19, the positioning piece includes a stopper 21 and a spring 22, a mounting groove 23 is provided at the end of the second rod 16, the spring 22 is placed in the mounting groove 23, two ends of the spring 22 respectively abut against the mounting groove 23 and the stopper 21, the spring 22 is used to drive the stopper 21 to partially extend out of the positioning hole 19, so as to achieve the relative position fixing of the second rod 16 and the first rod 15.

[0039] In the initial state, the spring 22 drives the stopper 21 to partially extend out of the positioning hole 19. At this time, the stopper 21 is respectively located in the positioning hole 19 and the mounting groove 23, thereby completing the fixation of the relative position of the first rod 15 and the second rod 16. When the length of the telescopic rod needs to be adjusted, the stopper 21 is pressed to separate the stopper 21 from the positioning hole 19, so that the first rod 15 and the second rod 16 can move relatively. After the movement is completed, the spring 22 drives the stopper 21 to extend out of the positioning hole 19 again to complete the re-fixation.

[0040] Preferably, the outer shell 7 is provided with a blocking cloth 24 corresponding to the entrance and exit 9 and the window 10, one end of the blocking cloth 24 is integrally connected to the outer shell 7, and the other end covers the entrance and exit 9 or the window 10, and the blocking cloth 24 is circumferentially provided with an extension portion 25 corresponding to the entrance and exit 9 or the window 10, and the extension portion 25 is used to limit the blocking cloth 24 to move only in a direction away from the sampling space 8 to open the entrance and exit 9 or the window 10.

[0041] In the initial state, the blocking cloth 24 covers the entrance 9 and the window 10, so that the entrance 9 and the window 10 are in a closed state. At the same time, the extension part 25 can keep the entrance 9 and the window 10 covered to reduce the generation of gaps. At the same time, due to the extension part 25, when the user pushes the blocking cloth 24 toward the sampling space 8 to open the entrance 9 and the window 10, there will be a great obstacle. Therefore, the user can be effectively guided to open the entrance 9 and the window 10 by pulling the blocking cloth 24, thereby avoiding the defect that pushing the blocking cloth 24 easily brings external airflow into the sampling space 8 and pollutes the sampling space 8.

[0042] Preferably, a filter unit 26 is also included, and an installation space is formed on the top of the inner support frame 1, and the filter unit 26 is arranged corresponding to the installation space. This part is the prior art and will not be elaborated here. An installation space is opened on the top of the inner support frame 1, and the filter unit 26 is arranged corresponding to the installation space. Specifically, a support plate 27 is also included, and the support plate 27 is arranged on a side of the upper frame 2 away from the sampling space 8. The installation space is the space where the upper end surface of the support plate 27 is located.

[0043] Preferably, a positive pressure unit is also included, which is connected to the sampling space 8 and is used to provide positive pressure to the sampling space 8 to drive the airflow in the sampling space 8 to flow to the outside. Specifically, the positive pressure unit can be a fan, which is connected to a purification device to deliver pollution-free positive pressure airflow to the sampling space 8, so that a positive pressure is formed in the sampling space 8 relative to the outside. On the one hand, since the filter unit 26 will extract the gas in the sampling space 8 when in use, the air pressure in the sampling space 8 is reduced, which makes it easy for external gas to enter. The positive pressure provided by the positive pressure unit can effectively eliminate the adverse effects of the filter unit 26. At the same time, when the baffle 24 is opened, the positive pressure provided by the positive pressure unit can drive the airflow to move to the outside, thereby avoiding the entry of external gas at this position to ensure a sterile environment in the sampling space 8.

[0044] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
