[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Please refer to Figures 1-4 and Figure 4 , the present invention provides a portable sterile test chamber, including a test chamber body 1 with a chamber lid 2 installed on the top. Protective boxes 3 are symmetrically and fixedly connected to both ends of the test chamber body 1. A self-returning rotating shaft 12 is rotatably connected to the inner wall of the protective box 3. A shoulder strap 5 is wound around the surface of the self-returning rotating shaft 12. A strip-shaped opening 4 is drilled at the top end of the protective box 3, and the shoulder strap 5 passes through the strip-shaped opening 4 to the outside of the protective box 3. A slot hole engaged with the self-returning rotating shaft 12 is fixedly drilled at the side end of the protective box 3. A limit block 14 located outside the protective box 3 is fixedly connected to the side end of the self-returning rotating shaft 12. Slide grooves 20 are symmetrically drilled at both ends of the limit block 14. Blocks 15 are slidably connected in the slide grooves 20. A compression spring 18 is fixedly connected between the two blocks 15. Clamping plates 16 are fixedly connected to the side of the protective box 3 on both sides of the limit block 14, and the clamping plates 16 are designed with one above the other and staggered for the two blocks 15, and the blocks 15 are in contact with the clamping plates 16. Electromagnetic blocks 19 are fixedly connected to the mutually approaching ends of the two blocks 15, and the two electromagnetic blocks 19 attract each other.

[0027] This solution can be realized. When carrying the test box body 1 out for soil detection, the clamping blocks 15 on both sides can be held by hand and squeezed against each other. During the squeezing process, the hand touches the controller 17, thereby turning on the electronic device 13 (model SR626SW), making the electromagnetic block 19 magnetic. At this time, the two clamping blocks 15 are squeezed against each other to compress the compression spring 18 and then retracted into the limit block 14 and fixed by the attraction of the electromagnetic block 19. Thus, when pulling the shoulder strap 5, the self-returning rotating shaft 12 can be driven to rotate, lengthening the shoulder strap 5, so as to adjust it to a length suitable for carrying on the shoulder. After adjustment, the controller 17 can be touched again to turn off the electromagnetic block 19, so that the clamping blocks 15 automatically pop out of the limit block 14 by the elastic force of the compression spring 18 and abut and engage with the clamping plate 16, making the self-returning rotating shaft 12 unable to automatically return, limiting the shoulder strap 5. Effectively, when carrying the test box body 1 out, it can be carried on the shoulder to free both hands, and the length of the shoulder strap 5 can be freely adjusted.

[0028] Embodiment 2

[0029] Please refer to Figure 1 , a controller 17 is fixedly installed at the side end of the clamping block 15, an electronic device 13 is installed on the inner side wall of the protective box 3, and the electronic device 13 is electrically connected to the controller 17. A handle 8 is installed at the top end of the box cover 2. Lock catches 11 are fixedly connected to the four corners of the top end of the box cover 2. A connecting rope 9 is detachably connected to the lock catch 11, and one end of the connecting rope 9 away from the lock catch 11 is fixedly connected to the bottom wall of the clamp 10. A collar is fixedly connected to the end of the connecting rope 9 close to the lock catch 11, and the collar is engaged with the lock catch 11. A clamp 10 is fixedly connected to the top end of the box cover 2 directly below the handle 8, and the handle 8 is engaged with the clamp 10. When it is necessary to carry the test box body 1 by hand, the handle 8 can be taken out of the clamp 10 and lifted, so that the handle 8 is connected to the lock catch 11 through four connecting ropes 9, thereby lifting the test box body 1. Since the four connecting ropes 9 are distributed at the four corners of the box cover 2, the test box body 1 can be stabilized, avoiding the effect of the test box body 1 shaking greatly from side to side when walking with it lifted, which may cause collision damage to the instruments inside the test box body 1. And when the handle 8 is not in use, it can be clamped in the clamp 10 for fixation.

[0030] Please refer to Figure 1, one end of each of the two shoulder straps 5 located outside the protective box 3 is fixedly connected with a first buckle 6 and a second locking buckle 7 respectively, and the first buckle 6 is engaged with the second locking buckle 7. The cross-sectional width of the first buckle 6 and the second locking buckle 7 is greater than the width of the strip-shaped opening 4, and both the first buckle 6 and the second locking buckle 7 are stuck outside the strip-shaped opening 4. When using the shoulder strap 5 to carry on the back, after adjusting the shoulder strap 5 to an appropriate length, the first buckle 6 and the second locking buckle 7 can be engaged and locked, and the shoulder strap 5 can be formed into a backpack strap and carried on the shoulder. If the shoulder strap 5 is not used, the first buckle 6 and the second locking buckle 7 can be unfastened, and the shoulder strap 5 can be disconnected and respectively retracted to the protective box 3, so as to avoid the shoulder strap 5 getting stuck on the box cover 2 and affecting the use of the clamp 10.

[0031] The working principle and usage process of the present utility model: During the use of the present utility model, first, when going out to carry the test box body 1 for soil detection, the two clamping blocks 15 on both sides can be held and squeezed against each other. During the squeezing process, the hand touches the controller 17, thereby turning on the electronics 13, making the electromagnetic block 19 magnetic. At this time, the two clamping blocks 15 are squeezed against each other to compress the compression spring 18 and then retracted into the limiting block 14 and fixed by the attraction of the electromagnetic block 19. Thus, when pulling the shoulder strap 5, the self-returning rotating shaft 12 can be driven to rotate, lengthening the shoulder strap 5, so as to adjust it to a length suitable for carrying on the shoulder. After adjustment, the controller 17 can be touched again to turn off the electromagnetic block 19, so that the clamping block 15 automatically pops out of the limiting block 14 by the elastic force of the compression spring 18 and abuts and engages with the clamping plate 16, making the self-returning rotating shaft 12 unable to automatically return, limiting the shoulder strap 5, effectively achieving the effect that when going out to carry the test box body 1, it can be carried on the shoulder to free both hands and freely adjust the length of the shoulder strap 5.

[0032] Then, when it is necessary to carry the test box body 1 by hand, the carrying handle 8 can be taken out of the clamp 10 and lifted, so that the carrying handle 8 is connected to the lock catch 11 through four connecting ropes 9, thereby lifting the test box body 1. Since the four connecting ropes 9 are distributed at the four corners of the box cover 2, the test box body 1 can be stabilized, avoiding the effect that when lifting the test box body 1 and walking, it swings greatly left and right, causing collision damage to the instruments inside the test box body 1. And when the carrying handle 8 is not used, it can be stuck in the clamp 10 for fixation.

[0033] Finally, when using the shoulder strap 5 to carry on the back, after adjusting the shoulder strap 5 to an appropriate length, the first buckle 6 and the second locking buckle 7 can be engaged and locked, and the shoulder strap 5 can be formed into a backpack strap and carried on the shoulder. If the shoulder strap 5 is not used, the first buckle 6 and the second locking buckle 7 can be unfastened, and the shoulder strap 5 can be disconnected and respectively retracted to the protective box 3, so as to avoid the shoulder strap 5 getting stuck on the box cover 2 and affecting the use of the clamp 10.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
