The technical features of the application can be interactively combined on the premise of no contradiction and conflict.

Referring to fig. 1 to 4, for example, a foldable stop rail for a lactating sow includes a rail frame, an accommodating space 100 is provided in the rail frame, the rail frame includes two uprights 200 disposed on the right side in tandem, sliding grooves 210 disposed along the up-down direction are provided on the upper sides of the two uprights 200, a foldable rail plate is provided between the uprights 200, the foldable rail plate includes an upper rail plate 410 and a lower rail plate 420 hinged to the lower side of the upper rail plate 410, sliding blocks 412 are provided on the front side and the rear side of the upper rail plate 410, two sliding blocks 412 slide along adjacent sliding grooves 210 respectively, return springs 300 are provided in the two sliding grooves 210, two ends of the return springs 300 respectively abut against the bottom surfaces of the sliding grooves 210 and the bottom surfaces of the sliding blocks 412, and the lower side of the lower rail plate 420 is hinged to the lower side of the upright 200.

Specifically, the pole setting sets up along upper and lower direction, the horizontal pole sets up in the horizontal plane, and this spacing main frame is constituteed with the horizontal pole to pole setting and horizontal pole's quantity can be many.

When the sow needs to lie on one side or a movable space is sought to the side, the side surface of the limiting fence can be propped up by the sow by the arrangement of the folding fence, so that a larger movable space is formed; when the sow is not occupying the space, the folding breast board is restored to the upright state under the action of the return spring, and the side space is not occupied.

Through setting up folding breast board, horizontal space accessible folding breast board's rotation in the spacing fence increases to sow's activity space is great, reduces the sow and because of the limb hoof damage that the space is little brings.

Further as a preferred embodiment, a limiting post 220 is further disposed in the chute 210, and the return spring 300 is sleeved outside the limiting post 220. The limiting column is arranged, so that the sliding block can be limited, and the spring is not easy to be compressed for a long time to cause failure because the sow occupies the space of the folding breast board for a long time.

Further as a preferred embodiment, the sum of the lengths of the upper and lower rail plates 410, 420 corresponds to the length of the upright 200, so that the upper and lower rail plates 410, 420 can be folded into a vertical state. Specifically, the sum of the lengths of the upper baffle plate and the lower baffle plate is smaller than the distance from the hinging point at the bottom of the vertical rod to the top of the chute. Therefore, the upper baffle plate and the lower baffle plate can return to the upright state under the action of the restoring spring.

Further as a preferred embodiment, the lower side of the lower baffle 420 is provided with a first rotating shaft 421, the first rotating shaft 421 is rotatably connected with a first rotating hole provided at the lower side of the upright rod 200, the upper side of the lower baffle 420 is provided with a rotating part, the rotating part is provided with a second rotating hole 4221, the middle part of the rotating part is provided with a notch 4222, the size of the notch 4222 corresponds to the width of the upper baffle 410, the lower side of the upper baffle 410 is provided with a second rotating shaft 411, and the second rotating shaft 411 rotates around the second rotating hole 4221. The upper and lower breast boards can simply realize folding function.

Further as a preferred embodiment, a spring piece 600 is further disposed between the hinge portions of the elastic membrane 500 and the upper and lower rail plates 410 and 420, the spring piece 600 is arc-shaped, the spring piece 600 extends to the elastic membrane 500, and the spring piece 600 abuts against the right side of the elastic membrane 500. When the sow lies on one side, the hinged parts of the upper breast board and the lower breast board can be extruded when the sow is folded, and the body of the sow is extruded at the parts to cause injury. When the upper breast board and the lower breast board are in a non-vertical state, the elastic film arches towards the inner side of the limiting breast, and can separate the extrusion space of the hinge part when the upper breast board and the lower breast board are closed, so that the sow can be prevented from being extruded when the upper breast board and the lower breast board rotate.

Further as a preferred embodiment, a spring piece 600 is further disposed between the hinge portions of the elastic membrane 500 and the upper and lower rail plates 410 and 420, the spring piece 600 is arc-shaped, and the spring piece 600 extends to the elastic membrane 500. Through setting up this shell fragment, can guarantee better that this elastic membrane receives shell fragment elasticity effect to the inboard arch of spacing fence when last breast board, lower breast board rotate, play the effect that prevents to press from both sides the wound.

Further as a preferred embodiment, the spring 600 is fixed to the underside of the upper rail 410.

Further as a preferred embodiment, the spring 600 is fixed to the upper side of the lower rail 420.

While the preferred embodiment of the present application has been described in detail, the present application is not limited to the embodiments described above, and various equivalent modifications and substitutions can be made by those skilled in the art without departing from the spirit of the present application, and these equivalent modifications and substitutions are intended to be included in the scope of the present application as defined in the appended claims.
