Description

Technical Field

[0001] The utility model relates to the technical field of special pens for sheep immunization, in particular to a portable movable special pen for sheep immunization. Background Art

[0002] Immunity refers to the function of the body's immune system to recognize self and foreign substances, and to eliminate antigenic foreign substances through immune responses to maintain the body's physiological balance. Immunity is a physiological function possessed by both animals and humans. Animals or humans rely on this function to recognize their own and non-self components, thereby destroying and rejecting antigenic substances entering the body to maintain physical health. A special pen for sheep immunization is a guardrail that fixes sheep and injects vaccines into the sheep to increase their resistance. The guardrail is fixed on a base, and the base can move through the wheels at its bottom.

[0003] After retrieval: A portable movable special pen for sheep immunization with the Chinese patent publication number CN209847454U includes a main body pile, a fixing frame, and a base fixed below the main body pile by screws. A plurality of rotating shafts are rotatably connected to the outer surface of the main body pile. A plurality of card holes are integrally formed on the outer surface of the rotating shaft. A plurality of springs are fixed to the inner wall of the rotating shaft by screws. The main body pile and the rotating shaft are rotatably connected by a plurality of bearings. A plurality of fixing piles are sleeved inside the base.

[0004] However, the above-mentioned special pen for sheep immunization still has deficiencies in use. Although it is conducive to splicing and disassembly, it is not conducive to movement. Some are provided with wheels at the bottom of the special pen for sheep immunization for movement, but after moving, personnel need to step on the brake pads on the wheels one by one to firmly fix the special pen. When moving, the brake pads on the wheels need to be lifted one by one to unlock the wheels, resulting in troublesome and inconvenient use. Moreover, the special pen for sheep immunization is inconvenient to fix the sheep. When injecting vaccines into the sheep, the sheep can move inside the special pen for sheep immunization, affecting the normal injection of vaccines. Therefore, we propose a portable movable special pen for sheep immunization to solve the above problems. Content of the Utility Model

The two connecting plates 308 are respectively slidably sleeved in the corresponding guiding holes. The lifting plate 309 is slidably sleeved in the base 1, which is convenient for guiding the lifting plate 309 and the connecting plates 308, making their movement more stable.

[0033] In the present utility model, during operation, loosen the screw 234 so that it does not fix the vertical plate 233. Pull the limiting plate 231, the three horizontal plates 232 and the vertical plate 233 forward without blocking the guardrail 2. At this time, the sheep can be driven into the guardrail 2. Then, push the guardrail door 23 backward to block the guardrail 2 and fix it with the screw 234. Furthermore, the sheep can be restricted in the guardrail 2. Through the four straps one 24, the four sheep legs can be tied. Through the two straps two 25, the sheep body can be tied. Through the two straps three 26, the sheep's head and neck can be tied to the top of the uppermost cross beam 22. Furthermore, the sheep to be vaccinated can be comprehensively fixed to prevent the sheep from moving in the guardrail 2 and affecting the normal vaccination.

[0034] When movement is required, the threaded rod 302 is rotated by the handwheel 301. The threaded rod 302 drives the moving plate 313 and the trapezoidal block 312 to move leftward without squeezing the triangular block 310 and the lifting plate 309. At this time, under the elastic force of the spring 311, the lifting plate 309, the two connecting plates 308 and the arc-shaped internal gear 307 move upward and abut and mesh with the external gear 306, thus not locking the rotating shaft 304 and the moving wheel 305. At this time, the guardrail 2 can be pushed to the designated position by the four moving wheels 305, improving the flexibility and convenience of the device. After moving to the designated position, the threaded rod 302 is rotated in the reverse direction, causing the trapezoidal block 312 to move rightward and squeeze the triangular block 310. The downward movement of the triangular block 310 drives the lifting plate 309, the two connecting plates 308 and the arc-shaped internal gear 307 to move downward and firmly abut and mesh on the outside of the external gear 306, thereby locking the external gear 306, the rotating shaft 304 and the moving wheel 305, improving the stability of the guardrail 2 during use, and preventing the sheep from feeling pain and moving around during the vaccination, which may cause the guardrail 2 to shake and affect the normal vaccination work.
