DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0024] See attached Figure 1 As shown, the embodiment of the present application provides a gas sampling device, including a gas sampling pump 4, a microbial sampler 5, a tripod 1 and a carrying platform 2, wherein the carrying platform 2 is mounted on the tripod 1, and the microbial sampler 5 and the gas sampling pump 4 are placed on the carrying platform 2. Among them, the microbial sampler 5 and the gas sampling pump 4 are both existing conventional instruments, and are not described in detail here.

[0025] In this embodiment, see Figure 4As shown, a connecting bolt head 101 is provided on the top of the tripod 1 for forming a threaded connection with the carrying platform 2 , thereby facilitating the assembly and disassembly between the carrying platform 2 and the tripod 1 .

[0026] like Figure 2 As shown, the bearing platform 2 includes a first bearing plate 201, a second bearing plate 202 and a third bearing plate 203, the second bearing plate 202 is in the center, and the first bearing plate 201 and the third bearing plate 203 are rotatably connected to both sides of the second bearing plate 202 through a damping hinge 3. A connecting plate 13 is fixedly mounted on the bottom of the second bearing plate 202 by screws, and a threaded sleeve 14 is arranged at the center of the connecting plate 13. The tripod 1 screws the connecting bolt head 101 at the top into the threaded sleeve 14, thereby realizing the assembly of the tripod 1 and the bearing platform 2.

[0027] like Figure 3 As shown, the damping hinge 3 includes a fixed hinge 302 and a movable hinge 301, the fixed hinge 302 is fixed to the second bearing plate 202 by screws, and the movable hinge 301 is respectively fixed to the first bearing plate 201 and the third bearing plate 203 by screws. Specifically, a pair of pivot sleeves 303 are arranged on one side of the fixed hinge 302 adjacent to the movable hinge 301, a guide sleeve 304 is arranged at the center between the pivot sleeves 303, the pivot sleeves 303 and the guide sleeve 304 are coaxial, and a movable shaft 306 is arranged in the pivot sleeves 303 and the guide sleeves 304, and the movable shaft 306 rotates freely in the pivot sleeves 303 and the guide sleeves 304. The movable hinge 301 is provided with a connecting shaft sleeve 305 on one side adjacent to the fixed hinge 302. The connecting shaft sleeve 305 is placed between the pivot sleeve 303 and the guide sleeve 304 and is fixedly connected to the movable shaft 306, so that as the movable shaft 306 rotates, the first supporting plate 201 and the third supporting plate 203 can be driven to rotate relative to the second supporting plate 202, and the first supporting plate 201 and the third supporting plate 203 can be rotated to the lower bottom surface of the second supporting plate 202 and be parallel to the second supporting plate 202, so that the supporting platform 2 does not occupy more space when not in use. Of course, the first supporting plate 201 and the third supporting plate 203 can be rotated to be flush with the second supporting plate 202, thereby providing additional space for placing other sampling instruments.

[0028] Of course, no matter the first carrier plate 201 and the third carrier plate 203 are in the unfolded or folded state, the first carrier plate 201 and the third carrier plate 203 need to be kept stationary. Figure 3As shown, a damping sleeve 307 is provided at the midpoint of the guide sleeve 304, and the damping sleeve 307 is provided in a direction perpendicular to the axis of the guide sleeve 304, and the damping sleeve 307 and the guide sleeve 304 are vertically connected, and a damping rod 308 is provided in the damping sleeve 307 by a threaded connection. It can be imagined that when the first bearing plate 201 or the third bearing plate 203 needs to be rotated, the damping rod 308 only needs to be rotated outward to separate the damping rod 308 from the movable shaft 306, and the movable shaft 306 can be rotated due to the loss of the resistance of the damping rod 308; on the contrary, when the position of the first bearing plate 201 and the third bearing plate 203 needs to be locked, the damping rod 308 only needs to be rotated inward to make the damping rod 308 press against the rotating shaft to apply resistance to it, thereby preventing the rotating shaft from rotating, so that the first bearing plate 201 and the third bearing plate 203 cannot be rotated, and the position is locked.

[0029] In a preferred embodiment, Figure 1 As shown, a pair of fixed rails 6 are provided on the carrying platform 2, and a clamping cavity is formed between the fixed rails 6. The clamping cavity has a space suitable for the gas sampling pump 4. When in use, the gas sampling pump 4 is placed in the clamping cavity.

[0030] Since the gas sampling pump 4 will vibrate during use, in order to further restrict the gas sampling pump 4, such as Figure 1 As shown, a pair of elastic bands 7 are arranged between the fixed rails 6. After the gas sampling pump 4 is placed between the fixed rails 6, the elastic sleeve is put on the gas sampling pump 4 to fix it. At the same time, a shock-absorbing pad 8 is arranged in the clamping cavity, that is, on the supporting platform 2. The pad with a certain thickness can alleviate the vibration of the gas sampling pump 4 to a certain extent.

[0031] In addition, in this embodiment, Figure 1 As shown, a clamping sleeve 9 is provided on the carrying platform 2, and the clamping sleeve 9 has an inner cavity adapted to the microbial sampler 5. When in use, the microbial sampler 5 is placed in the clamping sleeve 9. At the same time, an anti-slip pad 10 is provided at the bottom of the clamping sleeve 9, that is, the surface of the carrying platform 2, for preventing the microbial sampler 5 from slipping during use and for protection.

[0032] In another preferred embodiment, Figure 1 As shown, a power socket 11 and a cable box 12 are also provided on the carrying platform 2. The power socket 11 is provided with a socket hole and a power cord. When in use, an external power source is connected through the power cord, and power is provided for the use of the gas sampling pump 4 through the power socket 11. Of course, the cable box 12 is provided with a box cover and is used to store the power cord to prevent the power cord from being scattered on the carrying platform 2 when not in use.

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
