[0001] The utility model relates to the technical field of hazardous chemicals, in particular to a portable base for a hazardous chemical detection device. Background Art

[0002] Hazardous chemicals is the abbreviation of dangerous chemicals, which refers to highly toxic chemicals and other chemicals that have properties such as poison, corrosive, explosive, flammable, and combustion-supporting, and are harmful to human body, facilities, and the environment. Hazardous chemicals need to be tested by detection equipment before use.

[0003] Existing hazardous chemical detection devices generally include a base and a detection instrument fixed on the base. When carrying, it is generally necessary for staff to carry it manually, which is inconvenient to carry. When installing the detection instrument between the base, the detection instrument is generally fixed to the base by bolts, which is troublesome to install. To this end, we propose a portable base for hazardous chemical detection devices. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 3A portable base for a hazardous chemical detection device includes a base plate 2, a limiting frame 5 is installed on the top of the base plate 2, a detector 7 is arranged inside the limiting frame 5, the detector 7 can be horizontally limited by the limiting frame 5, and the detector 7 can be fixed on the base plate 2, which is convenient to fix.

[0025] like Figure 2 and Figure 3 As shown, an open groove 12 is provided on one side of the base plate 2, and a strip connecting block 3 is provided inside the open groove 12. Both sides of the strip connecting block 3 are rotatably connected to the side of the open groove 12 through a connecting shaft 4. A pull rod 6 is installed on the top of the strip connecting block 3. The pull rod 6 is in a "U" shape. An accommodating groove 10 matching the shape of the pull rod 6 is provided on the top of the base plate 2. When the pull rod 6 is rotated to a horizontal position, the pull rod 6 is located in the accommodating groove 10. When in use, the pull rod 6 can be rotated into the accommodating groove 10, thereby reducing the space occupied by the base plate 2.

[0026] It should be noted that if Figure 3 As shown, there is a distance between the end of the strip-shaped connecting block 3 and the end of the opening groove 12 , so that when the pull rod 6 moves into the accommodating groove 10 , the end of the strip-shaped connecting block 3 will not collide with the end of the opening groove 12 .

[0027] like Figure 2 As shown, a plurality of brake universal wheels 11 are installed at the bottom edge of the bottom plate 2. In actual use, when the detector 7 needs to be used, the staff can rotate the pull rod 6 into the receiving groove 10, so that the detector 7 is exposed for use by the staff. When the detector 7 needs to be carried, the staff rotates the pull rod 6, moves the pull rod 6 out of the receiving groove 10, and rotates it to the other end of the bottom plate 2, as shown in FIG. Figure 3 As shown, the staff can pull the pull rod 6 to drag the bottom plate 2 under the action of the brake universal wheel 11, so as to conveniently move the detector 7 and make it easy to carry.

[0028] It should be noted that the distance between the two sides of the pull rod 6 is greater than the width of the detector 7, so that the pull rod 6 will not knock over the detector 7 during the rotation process.

[0029] like Figure 3 As shown, a piston sleeve 18 is installed at the bottom of the base plate 2, and a through groove 15 is also opened at the bottom of the base plate 2. The piston sleeve 18 is connected with the inside of the limiting frame 5 through the through groove 15. A sealing piston 16 is provided inside the piston sleeve 18. Under the action of the sealing piston 16, the pressure in the piston sleeve 18 can be adjusted, so that the detector 7 will be adsorbed and fixed in the limiting frame 5, and the fixation is relatively convenient.

[0030] It should be noted that a sealing frame 14 is installed on the inner side of the limiting frame 5, and the inner surface of the sealing frame 14 is sealed with the side of the detector 7. During actual use, the sealing frame 14 can seal the gap between the detector 7 and the limiting frame 5, so that when the sealing piston 16 moves in the piston sleeve 18, the gas in the piston sleeve 18 will not leak.

[0031] like Figure 1 and Figure 3 As shown, the bottom of the sealing piston 16 extends out of the piston sleeve 18, and a connecting plate 17 is installed at the bottom of the sealing piston 16, and fixed blocks 13 are installed on both sides of the connecting plate 17. The top of each fixed block 13 is rotatably connected to an adjusting screw 1, and threaded through holes 19 are opened on both sides of the top of the bottom plate 2. The top of the adjusting screw 1 passes through the threaded through hole 19 and is threadedly matched with the threaded through hole 19. In actual use, the position of the sealing piston 16 can be adjusted by rotating the adjusting screw 1 under the action of the threaded through hole 19, and the air pressure in the piston sleeve 18 can be adjusted.

[0032] It should be noted that if Figure 3 As shown, the bottom end of the connecting plate 17 is higher than the bottom end of the brake universal wheel 11 , so that when the base plate 2 is moved, the connecting plate 17 will not hinder the brake universal wheel 11 .

[0033] Specifically, when the utility model is in use, the detector 7 is first placed in the limiting frame 5, and then the two adjusting screws 1 are rotated synchronously. Under the action of the threaded through hole 19, the adjusting screw 1 will drive the sealing piston 16 to move along the piston sleeve 18, thereby increasing the space volume inside the piston sleeve 18, and reducing the internal air pressure of the piston sleeve 18. In this way, the detector 7 can be adsorbed and fixed in the limiting frame 5, and the fixation is convenient. The protective cover 9 can be canvas or other retractable and foldable materials. When it needs to be carried, the staff can rotate the pull rod 6 to move the pull rod 6 out of the accommodating groove 10, and then rotate the pull rod 6 to one end of the bottom plate 2, pull the pull rod 6, and under the action of the brake universal wheel 11, the detector 7 can be pulled to move, which is convenient to carry.

[0034] Furthermore, Figure 1 As shown, a protective cover 9 is installed inside the accommodating groove 10, and the other end of the protective cover 9 is fixed on the side of the pull rod 6. When the pull rod 6 is rotated to a position perpendicular to the base plate 2, the protective cover 9 covers the surface of the detector 7. When the detector 7 is moved, the protective cover 9 will cover the detector 7, so that external objects will not collide with the detector 7, thereby improving the protection effect of the detector 7.

[0035] Furthermore, Figure 1 As shown, a plurality of support bars 8 are installed on the side of the protective cover 9 to support the protective cover 9 so that the protective cover 9 can protect the detector 7 .

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
