DETAILED DESCRIPTION

[0044] The present invention will be further described below with reference to the accompanying drawings:

[0045] This embodiment:

[0046] See also Figure 1-7 In this embodiment, the sampling device includes two sets of handles 1, two sets of first sampling parts 2, two sets of second sampling parts 3 and a switching structure.

[0047] In this embodiment, the two sets of handles 1 are rotatably connected in the middle via a pin.

[0048] In this embodiment, the two groups of handles 1 are cross-arranged and can rotate along the pin axis.

[0049] The two sets of first sampling parts 2 are arranged on one side of the top ends of the two sets of handles 1 close to each other and are fixedly connected to the handles 1 for taking out solid samples.

[0050] In this embodiment, V-shaped teeth are provided on the side where the two groups of first sampling parts 2 are close to each other, so as to increase the friction of the first sampling parts 2 .

[0051] The two sets of second sampling parts 3 are arranged directly above the first sampling part 2 , and the two sets of second sampling parts 3 can be docked to take out powder samples or liquid samples.

[0052] In this embodiment, the second sampling part 3 is shaped like a hollow hemisphere. The second sampling part can be set as a replaceable device with a standard capacity of 1 ml, 3 ml, 5 ml or 10 ml. The sampling part of the indicated capacity can be installed according to actual needs, which can make sampling more accurate, thereby reducing the number of sampling times and reducing the risk of contamination; by rotating the handle 1, the two groups of second sampling parts 3 are docked to wrap the powder sample or liquid sample; the two groups of second sampling parts 3 after docking can form a complete sphere.

[0053] The switching structure is connected to the second sampling part 3 and is used to change the position of the second sampling part 3; the second sampling part 3 and the switching structure can be connected by screws and can be replaced.

[0054] In this embodiment, the second sampling portion 3 or the first sampling portion 2 is used for sampling by changing the position of the second sampling portion 3 .

[0055] like Figure 4 and Figure 7 As shown, the switching structure further includes: two groups of first connecting seats 5 , a bayonet 6 , a connecting rod 7 , a second connecting seat 8 , a sliding portion 9 and a clamping portion 10 .

[0056] Among them, the two groups of first connecting seats 5 are composed of a first supporting seat and a first rotating shaft. The two sides of the first rotating shaft are rotatably connected to the first supporting seat, and the middle of the first rotating shaft is fixedly connected to the bottom end of the second sampling part 3.

[0057] In this embodiment, the second sampling portion 3 can drive the first rotating shaft to rotate along the connection with the first supporting seat.

[0058] A through hole is formed on the surface of the first connecting seat 5 ; a first notch is formed at a position of the first rotating shaft corresponding to the through hole; a bayonet 6 is disposed in the through hole, and one end of the bayonet 6 can extend into the first notch.

[0059] In this embodiment, by inserting the bayonet 6 into the first notch, the rotation of the first rotating shaft can be restricted, thereby restricting the rotation of the second sampling portion 3.

[0060] The top end of the connecting rod 7 is fixedly connected to the bottom end of the first connecting seat 5; the second connecting seat 8 is composed of a second support seat and a second rotating shaft, both sides of the second rotating shaft are rotatably connected to the second support seat, and the middle of the second rotating shaft is fixedly connected to the bottom end of the connecting rod 7.

[0061] In this embodiment, the connecting rod 7 can drive the second rotating shaft to rotate along the connection with the second supporting seat.

[0062] A second notch is provided at one end of the second rotating shaft; a slideway is provided inside the sliding portion 9 so that the second connecting seat 8 is disposed in the slideway, and the sliding portion 9 is slidably connected to the second connecting seat 8 through the slideway.

[0063] In this embodiment, the second connecting seat 8 can move vertically inside the sliding portion 9 along the slideway.

[0064] The clamping portion 10 is composed of a vertical rod and two sets of horizontal rods. The two ends of the vertical rod are fixedly connected to one end of the two sets of horizontal rods; the other end of the horizontal rod passes through the corresponding position of the sliding portion 9 and can extend into the second notch.

[0065] In this embodiment, by inserting one of the vertical rods in the clamping portion 10 into the second notch, both the vertical sliding of the second connecting seat 8 and the rotation of the second rotating shaft can be restricted.

[0066] When it is necessary to switch the sampling tool, first pull the clamping part 10 outward so that the clamping part 10 disengages from the second notch. At this time, first rotate the connecting rod 7 outward so that the connecting rod 7 drives the second rotating shaft to rotate along the connection with the second support seat, and pull the second connecting seat 8 downward so that the second connecting seat 8 moves vertically downward along the slide inside the sliding part 9, thereby driving the second sampling part 3 to move downward. After moving to the bottom, push the clamping part 10 inward so that the clamping part 10 is inserted into the second notch again, limiting the second connecting seat 8 to the bottom position, and then pull the pin 6 outward so that the pin 6 disengages from the first connecting seat 5. At this time, rotate the second sampling part 3 so that the open end face of the second sampling part 3 is parallel to the sliding part 9, and insert the pin 6 into the first notch again to complete the switching of the sampling tool. At this time, the first sampling part 2 can be used to take out solid samples. Before switching, the second sampling part 3 can be used to take out powder samples and liquid samples, so that the same sampling device can be used to sample multiple different samples, which is convenient for use.

[0067] like Figure 3 and Figure 4 As shown, the switching structure further includes: two groups of elastic members 11; each group of elastic members 11 is arranged between the vertical rod and the sliding portion 9, and is sleeved on the outer surface of the horizontal rod, so as to enable the vertical rod to be inserted into the second notch.

[0068] In this embodiment, the elastic member 11 is a spring. When the clamping portion 10 moves in a direction away from the second notch, the elastic member 11 is stretched.

[0069] When sampling solid samples, it is necessary to fold the two sets of second sampling parts 3 to the outside of the first sampling part 2 through the switching structure to clamp the solid sample. This will increase the lateral area of ​​the entire sampling device. When sampling samples with certain bottle mouth diameters, the sampling device cannot be inserted into the bottle, thereby hindering sampling.

[0070] To solve the above problem, this embodiment proposes an implementation method, in which the sampling device further includes: a connecting structure; the connecting structure is provided between the sliding part 9 and the handle 1, and is used to connect and fix the sliding part 9 and the handle 1.

[0071] like Figure 5 As shown, the connection structure includes: a connecting sleeve 12 , a fixing sleeve 13 , a fixing member 19 , a driving structure, a base 14 and a vertical rod 20 .

[0072] Specifically, the top end of the connecting sleeve 12 is fixedly connected to the bottom end of the sliding part 9; the fixed sleeve 13 is arranged inside the connecting sleeve 12; the fixing member 19 passes through the corresponding positions of the fixed sleeve 13 and the connecting sleeve 12 in sequence, and is slidably connected to the fixed sleeve 13 and the connecting sleeve 12.

[0073] In this embodiment, the fixing member 19 is passed through the fixing sleeve 13 and the connecting sleeve 12 in sequence, thereby fixing the fixing sleeve 13 and the connecting sleeve 12 together.

[0074] The driving structure is connected to the fixing member 19 and is used to move the fixing member 19 horizontally.

[0075] In this embodiment, when the fixing member 19 moves outward, it is inserted into the fixing sleeve 13 and the connecting sleeve 12 in sequence.

[0076] The base 14 is provided at the bottom end of the fixed sleeve 13 and is fixedly connected to the fixed sleeve 13 ; the vertical rod 20 is provided between the base 14 and the handle 1 , and both ends of the vertical rod 20 are fixedly connected to the base 14 and the handle 1 respectively.

[0077] In this embodiment, the vertical rod 20 is used for support.

[0078] When the fixing member 19 moves horizontally, it will disengage from the connecting sleeve 12, thereby separating the connecting sleeve 12 from the fixing sleeve 13. At this time, the connecting sleeve 12, the entire switching structure and the second sampling part 3 can be removed, thereby preventing the switching structure and the second sampling part 3 from interfering with the sampling of solid samples.

[0079] A cylindrical pin is provided at one end of the fixing member 19 located inside the fixing sleeve 13 .

[0080] like Figure 5 As shown, the driving structure includes: a threaded rod 15 , a knob 16 , a moving member 17 and two sets of inclined plates 18 .

[0081] The threaded rod 15 passes through a corresponding position of the base 14 and is rotatably connected to the base 14 ; the top end of the knob 16 is fixedly connected to the bottom end of the threaded rod 15 .

[0082] In this embodiment, by rotating the knob 16 , the threaded rod 15 can be driven to rotate synchronously; and the base 14 supports the rotation of the threaded rod 15 .

[0083] The moving member 17 is sleeved on the outer surface of the threaded rod 15 and is threadedly connected to the threaded rod 15 ; the two sets of inclined plates 18 are symmetrically arranged on both sides of the moving member 17 and are fixedly connected to the moving member 17 .

[0084] In this embodiment, when the threaded rod 15 rotates, the moving member 17 moves vertically, and the moving member 17 drives the inclined plate 18 to move at the same time.

[0085] A sliding groove is provided on the surface of the inclined plate 18 so that the cylindrical pin is disposed in the sliding groove, and the inclined plate 18 is slidably connected to the cylindrical pin through the sliding groove.

[0086] In this embodiment, when the inclined plate 18 moves vertically, the sliding between the sliding groove and the cylindrical pin causes the fixing member 19 to move horizontally.

[0087] When driving, by turning the knob 16, the knob 16 will drive the threaded rod 15 to rotate synchronously; the threaded rod 15 will cause the moving part 17 to move vertically upward; the moving part 17 will also drive the inclined plate 18 to move; the inclined plate 18 slides between the slide groove and the cylindrical pin, causing the fixing part 19 to move horizontally.

[0088] The outer diameter of the base 14 is slightly larger than the outer diameter of the connecting sleeve 12 and is used to limit the position of the connecting sleeve 12 .

[0089] The sampling device further includes a sealing ring 4 , which is disposed at the joint between the two sets of second sampling parts 3 for sealing.

[0090] In this embodiment, the sealing ring 4 is fixedly connected to one group of the second sampling parts 3 and rotates synchronously with the group of the second sampling parts 3 .

[0091] The sampling device further includes: two groups of limit blocks 21 ; each group of limit blocks 21 is arranged on one side below the handle 1 and close to each other, for limiting the movement range of the two groups of handles 1 .

[0092] Working principle:

[0093] When the sampling device is in use and a solid sample needs to be sampled, the clamping portion 10 is first pulled outward to disengage the clamping portion 10 from the second notch. At this time, the connecting rod 7 is first rotated outward to make the connecting rod 7 drive the second rotating shaft to rotate along the connection with the second supporting seat, and the second connecting seat 8 is pulled downward to make the second connecting seat 8 move vertically downward along the slideway inside the sliding portion 9, thereby driving the second sampling portion 3 to move downward. After moving to the bottom, the clamping portion 10 is pushed inward so that the clamping portion 10 is inserted into the second notch again. The second connecting seat 8 is restricted to the lowermost position in the mouth, and then the bayonet 6 is pulled outward so that the bayonet 6 is disengaged from the first connecting seat 5. At this time, the second sampling part 3 is rotated, and the open end face of the second sampling part 3 is parallel to the sliding part 9, and the bayonet 6 is inserted into the first notch again to complete the switching of the sampling tool. At this time, the first sampling part 2 can be used to take out solid samples, and before switching, the second sampling part 3 can be used to take out powder samples and liquid samples, so that the same sampling device can be used to sample a variety of different samples, which is easy to use.

[0094] When sampling samples with some bottle mouth diameters, by turning the knob 16, the knob 16 will drive the threaded rod 15 to rotate synchronously; the threaded rod 15 will cause the movable part 17 to move vertically upward; the movable part 17 will simultaneously drive the inclined plate 18 to move; the inclined plate 18 slides between the slide groove and the cylindrical pin, causing the fixing part 19 to move horizontally inward; the fixing part 19 will disengage from the connecting sleeve 12, thereby separating the connecting sleeve 12 from the fixing sleeve 13. At this time, the connecting sleeve 12, the entire switching structure and the second sampling part 3 can be removed, thereby avoiding the switching structure and the second sampling part 3 interfering with the sampling of solid samples, and completing the use of this device.
