It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "back", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The embodiment relates to an atmospheric sampling instrument support frame which is used for placing and supporting an atmospheric sampling instrument and is characterized in that the height of a bearing box of the atmospheric sampling instrument support frame is adjustable, so that the atmospheric sampling instrument can meet the sampling requirements of different heights of atmosphere. Meanwhile, the height adjusting structure has foldability, and the space occupied by the height adjusting structure after the height adjusting structure is folded is small, so that the support frame is easier to carry.

Based on the above design concept, an exemplary structure of the atmospheric sampling instrument support frame of the present embodiment is shown in fig. 1, and includes a bottom frame 1, a height adjusting structure, and a carrying box 6. The bolt connection has driving motor 2 on chassis 1, is connected with lead screw 3 in driving motor 2's power take off end, and the spiro union has mount pad 4 on lead screw 3, and mount pad 4 can move along the axis direction of lead screw 3 because of driving motor 2 drive lead screw 3 rotates. The fixing method of the motor 2 is not limited to bolt connection, but also includes other fixing connection methods, and this embodiment is only one of the preferable methods.

The height adjusting structure of the present embodiment includes a scissor-type link assembly 5 formed by a plurality of links being hinged. The bottom end of the connecting rod assembly 5 is respectively connected to the underframe 1 and the mounting seat 4. Although the height can be adjusted by adopting one group of height adjusting structures, the bearing stability of the height adjusting structures is difficult to control, so that two groups of corresponding height adjusting structures are selected to be respectively arranged on two sides in the embodiment to improve the bearing stability of the height adjusting structures. In a similar way, the utility model discloses a be not limited to and use two sets of altitude mixture control structures, also the optional multiunit that uses.

The bearing box 6 in the embodiment is arranged above the bottom frame 1 and connected to the top end of the connecting rod assembly 5 to bear the atmosphere sampling instrument, and the bearing box 6 drives the connecting rod assembly 5 to fold and unfold due to the movement of the mounting seat 4, so that the position of the sampling instrument in the height direction can be adjusted.

In a specific structure, as shown in fig. 2, a mounting plate is welded on the bottom frame 1, the lead screw 3 is pivotally connected to the mounting plate through a pivot hole 11, and a power output end of the driving motor 2 is connected with one end of the lead screw 3. The fixing manner of the mounting plate and the chassis 1 is not limited to welding, but may be other fixing and connecting manners, for example, the mounting plate and the chassis 1 are a whole plate, and are bent into the state as shown after being cut into a specific shape.

As shown in fig. 2 and 3, first hinge holes 12 are formed in the base frame 1 and the mounting seat 4, respectively, and as shown in fig. 1, the lower end of the link assembly 5 is hinged in the first hinge hole 12.

Then, with reference to fig. 1 and 4, a positioning block is welded to the bottom of the bearing box 6, a second hinge hole for connecting the connecting rod assembly 5 is formed in the positioning block, a fixing seat 61 is welded to the bottom of the bearing box 6, two ends of a rotating shaft 7 of the fixing seat 61 are provided with threads, the middle of the rotating shaft 7 is a smooth round rod, the round rod is fixedly arranged through a threaded hole in the fixing seat 61, a sliding block 63 is slidably arranged on the rotating shaft 7, a second hinge hole 62 is formed in the sliding block 63, and the upper end of the connecting rod assembly 5 is hinged to the second hinge hole 62. Corresponding to the sliding block 63, a groove extending along the axial direction of the rotating shaft 7 is arranged at the bottom of the bearing box 6, and the sliding block is further limited in position.

Meanwhile, as shown in fig. 1, the bottom end of the bottom frame 1 is screwed with the caster 20, and the atmosphere sampling instrument can be directly pushed without folding a support when moving in a short distance, so that the movement is more convenient. The caster 20 can be locked and can not rotate, so that the position of the support frame is fixed and can not be displaced.

In order to improve the steadiness to the atmosphere sampling appearance, see fig. 5, the spiro union has wedge-shaped rubber stopper 65 on the inner wall of bearing box 6, and this stopper 65 has the inclined plane that can support tight atmosphere sampling appearance, and two relative stoppers 65 can press from both sides the side of pressing from both sides tight atmosphere sampling appearance to can carry out spacing fixed to the atmosphere sampling appearance. The material of the limiting block 65 is not limited to rubber, the fixing manner is not limited to screw connection, and soft elastic materials such as silica gel block can be adopted, and this embodiment is only an exemplary choice.

The atmospheric sampling appearance support frame of this embodiment places the atmospheric sampling appearance in bearing box 6 when using, carries out the spacing fixed of side to it by stopper 65. Then, the driving motor 2 is started, and the screw rod 3 connected with the output end of the driving motor 2 is driven by the driving motor 2 to rotate, so that the mounting seat 4 screwed on the screw rod 3 moves in the axial direction. The mounting seat 4 moves away from the motor, the connecting rod assembly 5 is folded, and the height of the bearing box 6 is reduced; conversely, the link assembly 5 is unfolded and the load-bearing box 6 is raised in height. Through the height of adjusting the bearing box 6, the sampling height of the atmosphere sampling instrument is adjusted, and the requirement for sampling the gases with different heights is met. Simultaneously because the chassis truckle 20 that sets up for the atmosphere sampling appearance support frame can promote in the short distance under the condition of not folding, thereby makes the removal of atmosphere sampling appearance more convenient. When the supporting frame of the atmosphere sampling instrument is pushed to be satisfactory, the caster 20 is locked, so that the caster does not displace any more. When this atmospheric sampling appearance support frame need select the distance transportation, only need fold link assembly 5 and accomodate, then the loading transportation can. The folded space is smaller, and the transportation is more convenient.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
