Description

Technical Field

[0001] The utility model relates to the technical field of animal pathogen samplers, in particular to an assembled animal pathogen sampler. Background Art

[0002] Animal-borne bacteria are pathogens of zoonotic diseases, that is, a pathogen can cause certain infectious diseases in both animals and humans, which are called zoonoses. The vast majority of these are zoonotic diseases that use animals as the source of infection. Humans become infected due to direct contact with sick animals or their contaminants and infection through bites from vector animals. These diseases mainly occur in livestock areas or natural foci. The main animal-borne bacteria are Brucella, Yersinia pestis and Bacillus anthracis.

[0003] For example, the patent document with announcement number CN 218860730 U discloses a sampler for infectious bacteria, including a sampling barrel, an air bag connected to its inner cavity is fixed on the upper end of the sampling barrel, a movable barrel is inserted on the lower side of the outer periphery of the sampling barrel, a first spring is fixed between the sampling barrel and the movable barrel, a first through cavity is opened on the lower side of the outer periphery of the sampling barrel, a second through cavity matching the first through cavity is opened on the lower side of the outer periphery of the movable barrel, a sealing plate matching the first through cavity is fixed on the inner end surface of the movable barrel, a cavity is opened on the lower end of the movable barrel, the sampling barrel includes a bottom plate fixedly arranged at its lower end, the bottom plate is inserted in the cavity, the radius of the bottom plate matches the outer radius of the sealing plate, a first limiting slide groove is fixed on the inner end surface of the sealing plate, and a second limiting slide rail slidingly matched with the first limiting slide groove is fixed on the outer periphery of the sampling barrel. The utility model improves the efficiency of sample collection.

[0004] However, due to the limitations of its own structure, this structure can often only perform a single animal pathogen sampling operation. In actual operation, it is necessary to manually disassemble and assemble the sampling head to complete the switching and use operations, which will inevitably lead to problems with the removal of animal pathogens. At the same time, the equipment cannot perform more efficient animal pathogen sampling and collection operations and cannot meet daily use needs. Therefore, it is urgent to design an animal pathogen assembly sampler to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an assembled animal pathogen sampler to solve the problem that the existing structure mentioned in the above background technology can only perform a single animal pathogen sampling operation due to its own structural limitations. In actual operation, it is necessary to manually disassemble and assemble the sampling head continuously to complete the switching and use operation, which will inevitably cause problems with the removal of animal pathogens. At the same time, the equipment cannot perform more efficient animal pathogen sampling and collection operations and cannot meet daily use needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled animal pathogen sampler, comprising a central sleeve frame, the outer surface of the central sleeve frame is sleeved with a connecting sleeve frame, the four sides of the connecting sleeve frame are fixedly connected to positioning side sleeve frames, the surface of the central sleeve frame is fixedly connected to a piston sleeve, and the interior of the piston sleeve is movably connected to a sampling rod;

[0007] The bottom bracket is movably connected to the bottom end of the center sleeve, a cross slot is provided on the surface of the bottom bracket, and the four sides of the surface of the center sleeve are movably connected to the sleeve seat through the cross slot.

[0008] Preferably, fixing bolts are provided at the four corners of the surface of the bottom bracket, and a toggle slider is fixedly connected to the top of the sleeve seat.

[0009] Preferably, a sampling head is movably connected inside the socket, and a docking groove is provided on the surface of the sampling head.

[0010] Preferably, a sealing strip is provided at the bottom of the connecting sleeve, and a limiting sliding groove is provided on the surface of the positioning side sleeve.

[0011] Preferably, a holding ball seat is fixedly connected to the top end of the sampling rod, and a return spring is sleeved on the outer surface of the sampling rod.

[0012] Preferably, the bottom end of the sampling rod is fixedly connected to a positioning seat, and the bottom end of the positioning seat is fixedly connected to a docking joint.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The animal pathogen assembly sampler can perform animal pathogen assembly sampling operations by means of a central sleeve frame, a connecting sleeve frame, a positioning side sleeve frame, a piston sleeve, a sampling rod, a bottom bracket, a cross slide, a sleeve seat, a fixing bolt, a toggle slider and a sampling head. In actual use, the staff first installs four sets of sleeve seats on the bottom bracket, and then fixes the bottom bracket at the bottom of the central sleeve frame through the fixing bolts at the four corners of the surface. At this time, the toggle slider on the surface of a single sleeve seat can be toggled to make it slide crosswise on the surface of the bottom bracket. Under the double limit of the groove and the limit slide groove on the surface of the positioning side sleeve frame, enter the internal center position of the central sleeve frame, and then press down the sampling rod inside the piston sleeve to eject the sampling head inside the sleeve seat to complete the animal pathogen sampling operation. After sampling, the sampling head is retracted into the interior of the sleeve seat along with the sampling rod, and then the sleeve seat inside the central sleeve frame is reset, and then the remaining sleeve seats are adjusted to the limit sliding position of the central sleeve frame in turn, so as to realize the assembled multiple rapid animal pathogen sampling operations, greatly improve the sampling efficiency, and reflect the practicality of the equipment design.

[0015] The animal pathogen assembly sampler further improves the overall use effect of the equipment by providing a central sleeve, a sampling rod, a bottom bracket, a docking groove, a sealing strip, a limiting slide groove, a holding ball seat, a reset spring, a positioning seat and a docking joint. In daily use, when the staff presses down the holding ball seat at the top of the sampling rod, the outer surface of the sampling rod is sleeved on the reset spring and can be limited and contracted inside the piston sleeve, and then drives the positioning seat and the docking joint at the bottom to adaptably dock to the docking groove on the surface of the sampling head, so that the sampling head can perform a more stable top pressure sampling operation along the sleeve seat. After the holding ball seat of the subsequent sampling rod is loosened, the sampling rod is quickly reset as a whole under the reset force of the reset spring, so that the top pressure inside the central sleeve is quickly released, and the sleeve seat is quickly adjusted. At the same time, the bottom bracket as a whole can also be quickly replaced and used at the bottom of the central sleeve, meeting the daily sampling and classification needs of different batches of animal pathogen groups, reflecting the comprehensiveness of the equipment design.
