Abstract
Description
Technical Field
[0001] This utility model relates to the field of veterinary technology, and more specifically, to a portable veterinary fecal sampler. Background Technology
[0002] In the process of animal disease diagnosis and treatment and epidemic prevention and control, the collection of fecal samples is a common and necessary operation, especially in non-laboratory environments such as outdoors, pastures, and mobile clinics. The demand for portable fecal sampling tools is particularly prominent. Traditional portable fecal samplers usually only have basic sampling functions and cannot achieve sealed storage after sample collection. This makes it easy for contamination, leakage or sample loss to occur during sample transportation, which in turn affects the accuracy of test results and may even pose a potential risk to the surrounding environment and human health.
[0003] In practical animal medical and field monitoring applications, fecal samples often need to remain in their original state for a considerable period of time after collection for subsequent laboratory analysis. Therefore, samplers not only need to be easy to carry and operate, but also need to have sample sealing and preservation functions. However, most existing technologies have neglected this requirement and lack effective sealing structure designs. After sample collection, additional containers are still needed for transfer and sealing, which is cumbersome and increases the possibility of cross-contamination. This greatly limits the efficiency and safety of their application in high-time-sensitive scenarios such as responding to sudden epidemics and field sampling. Utility Model Content

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a portable veterinary fecal sampler, which has the following beneficial effects:
[0017] 1. The sealing mechanism effectively solves the problem of inadequate sealing during sample collection by portable veterinary fecal samplers through a combination of sealing structures. First, the support plate and central rod inside the connecting sleeve form a stable support structure, ensuring the smooth progress of the sealing process. At the same time, the cooperation between the sealing block and the sliding rod can precisely adjust the position of the sealing block, ensuring consistent sealing performance under different operating conditions. When the sealing strip is inserted into the sealing groove, it can ensure that the external environment does not come into contact with the sample, avoiding the possibility of cross-contamination. The entire sealing process not only strengthens the protection of the sample but also avoids sample loss due to leakage during transportation.
[0018] 2. The locking mechanism adopts a multi-layered design of sealing block and sliding rod, combined with the configuration of movable groove and return spring, to ensure stable sealing of fecal samples inside the sampler. The sealing block can be precisely adjusted by sliding in the movable groove to ensure reliable and durable sealing effect. The cooperation between the locking sleeve and the threaded sleeve makes the locking process more stable and avoids loosening or leakage during operation. After the sample is collected, the locking mechanism can firmly fix the sealing block, further enhancing the sealing performance of the sampler.
[0019] 3. The sampling mechanism cleverly extracts animal feces into the sampler through the cooperation of the pressure rod and the outer cylinder. The rubber head at the bottom of the pressure rod slides against the inner wall of the outer cylinder. Utilizing the principle of air pressure, multiple sets of return springs cause the sealing block to move, thereby pushing the sealing plate to extract the sample. The tight combination of the sealing strip and the sealing groove of the sealing mechanism ensures that the sample will not leak during the sampling process. The entire sampling process is simple and efficient, ensuring the integrity of the sample throughout the collection, storage and transportation process, and avoiding contamination or loss.

A limiting plate 8 is fixedly provided inside the connecting sleeve 4, and a compression spring 9 is provided between the limiting plate 8 and the sealing plate 7. Multiple sets of compression springs 9 are provided. The locking mechanism includes a sealing block 10 and a locking sleeve 11. A movable groove 12 is opened inside the connecting sleeve 4, and multiple sets of sealing blocks 10 are provided, all of which slide within the movable groove 12. A sliding rod 13 is fixedly provided on the outer wall of each set of sealing blocks 10, and the sliding rods 13 are slidably connected to the connecting sleeve 4. The locking sleeve 11 slides on the outer wall of the fixed sleeve. A push block 14 is fixedly provided at the top end of the central rod 6. A threaded sleeve 15 is threadedly connected to the outer wall of the connecting sleeve 4, and a sampling head 16 is fixedly provided at the bottom end of the connecting sleeve 4.
[0030] A rubber head 17 is fixedly provided at the bottom of the pressure rod 2. The rubber head 17 slides inside the outer cylinder 1 and is used to move the rubber head 17 inside the outer cylinder 1 by manually pushing the pressure rod 2 to form a negative pressure to assist in the suction of feces into the sampler.
[0031] The outer wall of the outer cylinder 1 is equipped with a measuring mark 18, which is used to control and observe the sampling amount through the scale markings, so as to accurately grasp the sampling volume.
[0032] A sealing groove 19 is provided inside the sampling head 16, and a sealing strip 20 is fixedly provided on the bottom surface of the sealing plate 7. The sealing strip 20 is inserted into the sealing groove 19, so that the sealing plate 7 can make close contact with the sealing groove 19 through the sealing strip 20 when it is reset, thus completing the initial sealing of the sampling head 16.
[0033] A limiting rod 21 is fixedly provided on the top surface of the sealing plate 7. Multiple sets of limiting rods 21 are provided and are all slidably connected to the limiting plate 8. They are used to guide the sealing plate 7 along the limiting plate 8 during the up and down movement of the sealing plate 7, so as to ensure the smoothness and accuracy of the sealing action.
[0034] A set of return springs 22 are connected between the outer wall of the multiple sets of sealing blocks 10 and the inner wall of the movable groove 12. Multiple sets of return springs 22 are provided to automatically return to the initial position after the sealing block 10 slides, so as to facilitate the smooth execution of the next sealing action.
[0035] A sealing ring 23 is fixedly provided on the inner wall of the connecting sleeve 4. The sealing ring 23 abuts against the bottom surface of the push block 14 to form an additional sealing contact during the movement of the push block 14 and the central rod 6, thereby enhancing the overall sealing performance of the sealing structure.
[0036] A thrust bearing 24 is provided between the bottom surface of the threaded sleeve 15 and the locking sleeve 11. A slider 25 is fixedly provided on the inner wall of the locking sleeve 11. A groove 26 is provided on the outer wall of the connecting sleeve 4. Multiple sets of sliders 25 and grooves 26 are provided and are slidably connected. The connecting sleeve 4 and the connecting head 3 are threadedly connected. The threaded rotation drives the thrust bearing 24 to push the locking sleeve 11, so that the slider 25 slides along the groove 26 to fix the position of the slide rod 13, thereby achieving the locking of the sealing block 10 and the stable connection of the overall structure.
[0037] In this embodiment, during use, the sampling head 16 is placed in contact with the animal feces. Pulling the pressure block causes the rubber head 17 to slide along the inner wall of the outer cylinder 1. At this time, multiple sets of reset springs 22 pull multiple sets of sealing blocks 10 respectively. The air pressure inside the outer cylinder 1 pulls the push block 14. The push block 14 pulls the sealing plate 7 through the central rod 6 and slides along the limiting plate 8 through multiple sets of limiting rods 21, causing the sealing strip 20 to disengage from the sealing groove 19 and squeeze the multiple sets of pressure springs 9. The air pressure draws the animal feces into the outer cylinder 1. After sampling is completed... After completion, multiple sets of pressure springs 9 reset and push the sealing plate 7 to reset, causing the sealing strip 20 to be inserted into the sealing groove 19 to seal the sampling head 16. Then, multiple sets of sliding rods 13 are pushed to make multiple sets of sealing blocks 10 slide along the movable groove 12 to seal the movable groove 12. Then, the threaded sleeve 15 is rotated clockwise to engage with the connecting sleeve 4 and pushes the locking sleeve 11 to slide through the thrust bearing 24. When the multiple sleeves abut against the outside of the multiple sets of sliding rods 13 to fix the multiple sets of sealing blocks 10, the connecting sleeve 4 is in a continuous sealing state.
[0038] In summary, during use or operation of the entire device: When in use, the sampling head 16 is placed on the animal feces. Pulling the pressure block causes the rubber head 17 to slide along the inner wall of the outer cylinder 1. At this time, multiple sets of reset springs 22 pull multiple sets of sealing blocks 10 respectively. The air pressure inside the outer cylinder 1 pulls the push block 14. The push block 14, through the central rod 6, pulls the sealing plate 7, which slides along the limiting plate 8 through multiple sets of limiting rods 21. This causes the sealing strip 20 to disengage from the sealing groove 19 and compress the multiple sets of pressure springs 9. The air pressure then draws the animal feces into the outer cylinder 1. After sampling, multiple sets of compression springs 9 reset and push the sealing plate 7 to reset, so that the sealing strip 20 is inserted into the sealing groove 19 to seal the sampling head 16. Then, multiple sets of sliding rods 13 are pushed so that multiple sets of sealing blocks 10 slide along the movable groove 12 to seal the movable groove 12. Then, the threaded sleeve 15 is rotated clockwise to engage with the connecting sleeve 4 and pushes the locking sleeve 11 to slide through the thrust bearing 24. When the multiple sets of sleeves abut against the outside of the multiple sets of sliding rods 13 to fix the multiple sets of sealing blocks 10, the connecting sleeve 4 is in a continuous sealing state.
