[0036] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments, but the scope of protection claimed in the utility model is not limited to the following specific embodiments.

[0037] refer to Figure 1 and Figure 2 A sample cone of an analytical instrument comprises a connecting plate 11, a guide plate 21 and a handle 12.

The guide plate 21 is fixedly connected with a handle 27. The guide plate 21 is driven to move by pulling the handle 27, so as to prevent the guide plate 21 from being overheated and scalding the operator's hands, thereby achieving the effect of convenient use.

[0038] refer to Figure 2 and Figure 3 The connecting plate 11 is fixedly connected with a fixing buckle 14, the guide plate 21 is provided with a fixing groove 23 matched with the fixing buckle 14, the connecting plate 11 is slidably connected with a movable buckle 31, the guide plate 21 is provided with a movable groove 24 matched with the movable buckle 31, and the movable groove 24 is opposite to the direction of the fixing groove 23. The guide plate 21 is provided with a first inclined surface 25 located at the movable groove 24, and the first inclined surface 25 is inclined upward in a direction away from the movable buckle 31. The guide plate 21 is provided with a second inclined surface 26, and the second inclined surface 26 is inclined downward in a direction away from the movable groove 24. The movable buckle 31 abuts against the second inclined surface 26, and the first inclined surface 25 and the second inclined surface 26 are respectively located on both sides of the movable buckle 31.

[0039] The handle 12 is provided with a driving mechanism connected to the movable buckle 31, and the driving mechanism includes a rotating shaft 32, a screw rod 33 and a knob 34. The rotating shaft 32 is penetrated by the handle 12, the rotating shaft 32 is rotatably connected to the connecting plate 11 and axially linked, the knob 34 is fixedly connected to the rotating shaft 32, the knob 34 is located at the handle 12, the screw rod 33 is fixedly connected to the rotating shaft 32, and the screw rod 33 is threadedly connected to the movable buckle 31.

[0040] refer to Figure 2 and Figure 4, the connecting plate 11 is equipped with a heat-conducting shaft 41, and the heat-conducting shaft 41 is fixedly connected with a heat-conducting sheet 42. The heat-conducting shaft 41 is rotatably connected to the connecting plate 11. The connecting plate 11 is slidably connected with a push block 43, and the push block 43 abuts against the heat-conducting sheet 42. An elastic member 44 is provided between the connecting plate 11 and the heat-conducting shaft 41, and the two ends of the elastic member 44 are respectively connected to the connecting plate 11 and the heat-conducting shaft 41. The elastic member 44 is a torsion spring whose two ends are respectively fixedly connected to the connecting plate 11 and the heat-conducting shaft 41, and the elastic member 44 tends to flip the heat-conducting sheet 42 toward the connecting plate 11. There are a plurality of heat-conducting shafts 41 and heat-conducting sheets 42, and the plurality of heat-conducting shafts 41 and the plurality of heat-conducting sheets 42 correspond to each other one by one. Heat dissipation is performed simultaneously by the plurality of heat-conducting shafts 41 and heat-conducting sheets 42, which plays a role in improving the heat dissipation effect. The connecting plate 11 is rotatably connected with a screw 45, and the screw 45 is threadedly connected to the push block 43.

[0041] When sampling, the guide plate 21 is installed on the connecting plate 11, the fixed buckle 14 is inserted into the fixed groove 23, and then the movable buckle 31 is driven by the driving mechanism to be inserted into the movable groove 24. The fixed buckle 14 and the movable buckle 31 respectively apply opposite clamping forces on the fixed groove 23 and the movable groove 24 facing opposite directions, so that the guide plate 21 can be locked on the connecting plate 11 by the fixed buckle 14 and the movable buckle 31. Hold the handle 12 by hand, guide the sample into the guide groove 22, and let the sample flow into the sample groove 13 through the guide groove 22. The driving mechanism drives the movable buckle 31 to move in the direction away from the movable groove 24, so that the movable buckle 31 is disengaged from the movable groove 24, and the movable buckle 31 is continued to be driven to move so that the movable buckle 31 abuts against the second inclined surface 26. The movable buckle 31 provides thrust to the guide plate 21 on the second inclined surface 26, and pushes the guide plate 21 to move in the direction away from the connecting plate 11, so as to prevent the guide plate 21 and the connecting plate 11 from being stuck together due to the sample and unable to be disassembled, thereby facilitating the removal of the guide plate 21 from the connecting plate 11.

[0042] This embodiment has the following advantages:

[0043] The movable buckle 31 is driven to move by the driving mechanism to realize the function of locking and unlocking the guide plate 21 on the connecting plate 11, so that the guide plate 21 can be unlocked and locked without directly touching the guide plate 21 with hands, thereby effectively reducing the risk of scalding of the operator, and the operation process is more labor-saving and smooth, and the vibration of the connecting plate 11 and the guide plate 21 is effectively avoided, which causes the sample to splash, plays a role in facilitating use and improving safety, and has the advantage of being easy to use, and is suitable for sampling high-purity metal samples.

[0044] During use, the operator can adjust the position of the connecting plate 11 by holding the handle 12 and can turn the knob 34 at the handle 12, which effectively prevents the operator from being burned and achieves the advantage of convenient use.

[0045] The knob 34 is rotated at the handle 12 to drive the rotating shaft 32 and the screw rod 33 to rotate. The screw rod 33 drives the movable buckle 31 threadably connected thereto to move during the rotation process, thereby realizing the function of driving the movable buckle 31 to move through the driving mechanism.

[0046] When the movable buckle 31 is inserted into the movable groove 24 , it abuts against the first inclined surface 25 , so that the movable buckle 31 can press against the guide plate 21 on the first inclined surface 25 , so that the guide plate 21 can be fixed on the connecting plate 11 , thereby improving the structural stability between the guide plate 21 and the connecting plate 11 .

[0047] When the movable buckle 31 moves in the direction away from the movable groove 24, the movable buckle 31 abuts against the second inclined surface 26 and pushes the guide plate 21 along the inclined direction of the second inclined surface 26, so that the guide plate 21 moves in the direction away from the connecting plate 11, which makes it easy to remove the guide plate 21 from the connecting plate 11, thereby achieving the advantage of easy use.

[0048] After the sample enters the sample slot 13, it absorbs heat through the heat-conducting shaft 41 and the heat-conducting sheet 42, and diffuses the heat into the air through the heat-conducting sheet 42, thereby dissipating heat for the connecting plate 11 and the sample, increasing the cooling speed of the sample and reducing the temperature of the connecting plate 11, thereby facilitating use.

[0049] The heat-conducting shaft 41 is rotated on the connecting plate 11 to realize the function of flipping the heat-conducting sheet 42. When the connecting plate 11 does not need to be cooled, the heat-conducting sheet 42 is flipped toward the connecting plate 11 to reduce the space occupied by the connecting plate 11 and the heat-conducting sheet 42, which is convenient for transportation and storage. When the connecting plate 11 needs to be cooled, the heat-conducting sheet 42 is flipped toward the direction away from the connecting plate 11 to improve the heat dissipation efficiency.

[0050] The push block 43 is slid on the connection plate 11 toward the direction close to the heat-conducting shaft 41 , so that the push block 43 pushes the heat-conducting sheet 42 to flip toward the direction away from the connection plate 11 , thereby realizing the function of driving the heat-conducting sheet 42 to flip.

[0051] When the push block 43 slides in a direction away from the heat-conducting shaft 41, the elastic member 44 drives the heat-conducting sheet 42 to flip in a direction close to the connecting plate 11 along with the sliding of the push block 43. When the push block 43 moves to a position far from the heat-conducting shaft 41, the heat-conducting sheet 42 flips to a direction close to the connecting plate 11, thereby realizing the function of driving the heat-conducting sheet 42 to flip in different directions.

[0052] The screw rod 45 is rotated to drive the push block 43 threadably connected thereto to move, thereby realizing the function of driving the push block 43 to move on the connecting plate 11 .

[0053] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
