[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0030] See also Figures 1 to 7 In the utility model, a novel portable sampling device includes a sampling body 1, a receiving box 2 and a rain cover 3. The rain cover 3 is a U-shaped structure and covers the top of the receiving box 2. The sampling body 1 is fixedly installed on the inner side of the rain cover 3 and can be accommodated in the interior of the receiving box 2. The left and right sides of the receiving box 2 are provided with evenly distributed plug holes 4. The left and right sides of the rain cover 3 are fixedly connected with elastic plug-ins 5 that pass through the rain cover 3 and are adapted to the plug holes 4. The elastic plug-in 5 can be inserted into the plug hole 4 to fix the rain cover 3 and the receiving box 2. A plurality of legs 6 are interspersed at the bottom of the receiving box 2, and the legs 6 are slidably matched with the receiving box 2.

[0031] Among them, linkage mechanisms are provided on the left and right sides of the interior of the storage box 2, and the rain shelter cover 3 is divided into an open state and a closed state. When the rain shelter cover 3 is changed from the closed state to the open state, the rain shelter cover 3 moves upward and the linkage mechanism is used to extend the legs 6 out of the storage box 2 for support. When the rain shelter cover 3 is changed from the open state to the closed state, the rain shelter cover 3 moves downward and the linkage mechanism is used to retract the legs 6 to the storage box 2 for easy carrying.

[0032] In this embodiment, preferably, the two linkage mechanisms each include a first rotating shaft 7 rotatably disposed in the accommodating box 2, a second rotating shaft 8 rotatably disposed in the accommodating box 2 and located below the first rotating shaft 7, a first gear 9 and a first rotating wheel 10 fixedly sleeved on the outer wall of the first rotating shaft 7, a second rotating wheel 11 fixedly sleeved on the outer wall of the second rotating shaft 8, a transmission belt 12 arranged between the first rotating wheel 10 and the second rotating wheel 11, and a second gear 13 fixedly sleeved on the outer walls of both ends of the second rotating shaft 8, and first tooth grooves 31 meshing with the first gear 9 are provided on both left and right sides of the inner wall of the rainproof top cover 3, and a second tooth groove 61 meshing with the second gear 13 is provided on the side of the leg 6 close to the second gear 13;

[0033] Specifically, when the rain cover 3 goes up, the first gear 9 rotates and drives the first shaft 7 to rotate through the meshing of the first tooth groove 31 and the first gear 9. The rotation of the first shaft 7 can drive the first rotating wheel 10 to rotate and the second rotating wheel 11 drives the second rotating shaft 8 to rotate through the transmission belt 12. The second gears 13 located at both ends of the second rotating shaft 8 follow the rotation and the meshing of the second gear 13 and the second tooth groove 61 causes the support leg 6 to go down. Similarly, when the rain cover 3 goes down, the support leg 6 goes up.

[0034] In this embodiment, preferably, both left and right sides of the accommodating box 2 are provided with I-shaped through grooves 21, and the two linkage mechanisms are respectively accommodated in the two I-shaped through grooves 21, and the inner side of the rainproof top cover 3 is provided with a vertical groove 32, and the second gear 13 is accommodated in the vertical groove 32;

[0035] Specifically, the I-shaped through groove 21 and the vertical groove 32 provide space for the linkage mechanism.

[0036] In this embodiment, preferably, the top end of the leg 6 is fixedly connected to a limit plate 62 located in the accommodating box, and the bottom end of the leg 6 is fixedly connected to a support plate 63 located below the accommodating box;

[0037] Specifically, the limiting plate 62 and the supporting plate 63 limit the supporting leg 6 .

[0038] In this embodiment, preferably, each elastic plug 5 includes a cylinder 51 embedded in both sides of the rainproof top cover 3, a ring 52 slidably arranged in the cylinder 51, a plug rod 53 fixedly connected to the inner circle of the ring 52, and a spring 54 sleeved on the outside of the plug rod 53. Both ends of the plug rod 53 penetrate the outside of the cylinder 51, and one end of the plug rod 53 can be inserted into the corresponding jack 4. One end of the spring 54 is fixedly connected to one side of the ring 52, and the other end of the spring 54 abuts against the inner wall of the cylinder 51.

[0039] Specifically, the rod 53 can be separated from the socket 4 by pulling. When the rod 53 is pulled, the ring 52 is driven to squeeze the spring 54. When the rod 53 is released, the elastic force of the spring 54 pushes the ring 52 to insert the rod 53 into the socket 4. The above operation realizes the connection and separation of the rod 53 and the socket 4.

[0040] In this embodiment, preferably, a pull ring 14 is provided on both sides of the left and right sides of the rainproof top cover 3, and a plurality of pull rods 15 are fixedly connected to the outer wall of the pull ring 14, and one end of each pull rod 15 away from the pull ring 14 is fixedly connected to the insertion rod 53 at the corresponding position;

[0041] Specifically, the pull ring 14 is controlled to synchronously control the plurality of insertion rods 53 through a plurality of pull rods 15, which makes the use more convenient.

[0042] In this embodiment, preferably, the pull ring 14 and the pull rod 15 are both made of lightweight material components;

[0043] Specifically, the pull ring 14 and the pull rod 15 are made of lightweight materials, so the elastic force of the spring 54 can overcome the weight of the pull ring 14 and the pull rod 15 to reset the insertion rod 53.

[0044] In this embodiment, preferably, the bottom of the accommodating box 2 and the top of the rain shelter cover 3 are both fixedly connected with a handle 16, and when the rain shelter cover 3 completely covers the top of the accommodating box 2, the handle 16 at the bottom is accommodated on the inner side of the rain shelter cover 3.

[0045] The working principle and use process of this utility model:

[0046] When not in use, Figure 1 As shown, the sampling body 1 is located in the accommodating box 2, and the rain cover 3 and the accommodating box 2 are connected by the elastic plug 5 and the jack 4, and the whole can be lifted by the upper or lower handle 16 to achieve portability;

[0047] When the sampling body 1 is needed for sampling, the pull ring 14 is pulled and the insertion rod 53 is moved and separated from the insertion hole 4 through the pull rod 15. At this time, the rain cover 3 can be pulled upward through the handle 16 above so that the sampling body 1 is moved upward from the accommodating box 2 for use;

[0048] In the process of pulling the rain cover 3 upward, the first gear 9 rotates and drives the first shaft 7 to rotate through the meshing of the first tooth groove 31 and the first gear 9. The rotation of the first shaft 7 can drive the first rotating wheel 10 to rotate and the second rotating wheel 11 drives the second shaft 8 to rotate through the transmission belt 12. The second gears 13 located at both ends of the second shaft 8 rotate accordingly, and the meshing of the second gear 13 and the second tooth groove 61 causes the leg 6 to move downward until the lower insertion rod 53 moves to be flush with the upper insertion hole 4 and is inserted into the insertion hole 4. The rainproof cover 3 and the accommodating box 2 are fixed again in the socket 4 at the place. At this time, the support plate 63 at the lower end of the leg 6 is grounded and the whole is erected. The sampling body 1 is moved out of the accommodating box 2 for use. When the sampling body 1 is finished using, the contact rod 53 and the socket 4 cooperate to make the rainproof cover 3 drive the sampling body 1 downward. The above operation process is reversed to retract the leg 6 until the rod 53 cooperates with the corresponding socket 4 again to complete the storage. After storage, the overall volume of the device is small, which is convenient for carrying.

[0049] The electronic components and modules used in the content of this utility model can all be parts that are commonly used in the market and can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs. The electronic components and modules are all connected to an external power supply and a control switch for use. Their specific circuit connection methods and methods of use are commonly used public technologies and will not be elaborated on here.
