Description

Technical Field

[0001] The utility model belongs to the technical field of sampling tools, and more specifically, relates to a rotary sampler. Background Art

[0002] Currently, for CCM sampling, a circular metal column cutter is used for percussion sampling, where CCM stands for catalyst coating membrane; during percussion operation, sampling can cause the equipment to vibrate, thus resulting in safety problems and affecting the use of the equipment; during sampling, the percussion action needs to be repeated multiple times, wasting time; percussion sampling is also prone to causing damage to the CCM, affecting its appearance and performance.

[0003] If a disk sampler is used for sampling, the blade may still adhere after cutting, and at this time, the sample needs to be removed by hand. Since CCM is a material with relatively high cleanliness, direct hand contact may increase the risk of contamination, thus affecting its performance; if the number of samples is large, the number of adhesions will also increase accordingly, thus affecting efficiency.

[0024] The following disclosure provides many different embodiments or examples for implementing different solutions of the present utility model.

[0025] Refer to Figures 1 to 3As shown in the figure, a rotary sampler is provided, which includes a hollow housing 1 and a driving rod 2. One end of the housing 1 is provided with an eccentric hole 11, and the other end of the housing 1 is provided with a through hole 12. The driving rod 2 passes through the eccentric hole 11 and can move around the inner wall of the eccentric hole 11. The driving rod 2 is telescopically arranged in the housing 1. A blade 3 is arranged at one end of the driving rod 2, and the blade 3 can extend out of the through hole 12. A telescopic rod 21 for ejecting the sampled sample after cutting is arranged at one end of the driving rod 2 close to the through hole 12.

[0026] In this embodiment, the rotary sampler is placed on the sample to be sampled. The driving rod 2 is rotated to make the driving rod 2 move at the eccentric hole 11. When the driving rod 2 is coaxial with the through hole 12, the driving rod 2 is pressed to make the blade 3 on the driving rod 2 extend out of the through hole 12. Then the driving rod 2 is rotated, and the blade 3 cuts the sample. The telescopic rod 21 is used to eject the cut sample, reducing human contact and improving the qualified rate. The design of the eccentric hole 11 is to prevent accidental contact from causing the blade 3 to extend out of the through hole 12 and injuring the worker. The structure of this rotary sampler is simple and can complete sampling quickly.

[0027] In one embodiment of the present utility model, a knob 22 is connected to the end of the driving rod 2 away from the through hole 12. The knob 22 is convenient for the worker to rotate the driving rod 2. A button 23 for controlling the telescopic movement of the telescopic rod 21 is arranged on the knob 22. When the button 23 is pressed, the telescopic rod 21 extends towards the through hole 12. When the button 23 is pressed again, the telescopic rod 21 contracts towards the housing 1. The operation is simple. Preferably, the length of the telescopic rod 21 extending out of the through hole 12 exceeds the length of the blade 3 extending out of the through hole 12, which is convenient for ejecting the sample.

[0028] Furthermore, the surface of the knob 22 is provided with a first anti-slip pattern to prevent slipping when rotating the knob 22, improving the work efficiency.

[0029] In one embodiment of the present utility model, a first space 24 is arranged at one end of the driving rod 2 close to the through hole 12. The telescopic rod 21 is telescopically arranged in the first space 24. The first space is used for arranging the telescopic rod 21, which is convenient for hiding the telescopic rod 21.

[0030] In one embodiment of the present utility model, the housing 1 includes a fixed block 13, a cylinder 14 and an eccentric block 15. The two ends of the cylinder 14 are respectively fixedly connected to the fixed block 13 and the eccentric block 15. The through hole 12 is arranged on the fixed block 13, and the eccentric hole 11 is arranged on the eccentric block 15. The inside of the cylinder 14 is a hollow structure.

[0031] Further, a second anti-slip pattern is provided at one end of the fixing block 13 away from the cylinder 14. The second anti-slip pattern is used to frictionally fix with the sample to prevent the rotary sampler from slipping and shifting during operation, thereby affecting sampling. An inclined surface 131 for guiding the active rod 2 to the through hole 12 is provided at one end of the fixing block 13 away from the second anti-slip pattern. When directly pressing the active rod 2, one end of the active rod 2 touches the inclined surface 131 and will slide in the direction of the through hole 12 following the inclination of the inclined surface. The position of the active rod 2 at the eccentric hole 11 also changes accordingly until the active rod 2 is coaxial with the through hole 12 or the blade 3 extends out of the through hole 12, then the sliding stops. At this time, the active rod 2 can be rotated for cutting.

[0032] Preferably, a limiting block 4 is provided at one end of the eccentric block 15 away from the cylinder 14. The limiting block 4 covers the eccentric hole 11 to prevent other impurities from entering the housing 1. A knob 22 is fixedly connected to one end of the active rod 2 away from the through hole 12. An elastic member 5 is provided between the limiting block 4 and the knob 22. When the knob 22 is released, under the elastic force of the elastic member 5, the active rod 2 will automatically rebound to its original position, and the blade 3 follows the rebound into the housing 1 to prevent the blade 3 from causing harm to the worker.

[0033] A locking bolt 6 is provided on the limiting block 4. The locking bolt 6 can press against the active rod 2 to keep the active rod 2 in a locked state and unable to move, preventing accidental contact from causing the blade 3 to extend out of the through hole 12 and causing unnecessary harm. At the same time, after pressing to make the blade 3 extend out of the through hole 12, tighten the locking bolt 6 to fix the position of the active rod 2, and then rotation cutting can be performed without continuous pressing; when the locking bolt 6 is released, the active rod 2 can move freely and the blade 3 can also freely extend out of the through hole 12.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
