Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

In the description of the embodiments, the terms "disposed," "connected," and the like are to be construed broadly unless otherwise explicitly specified or limited. For example, the connection can be fixed, detachable or integrated; can be mechanically or electrically connected; either directly or through an intervening medium, or through internal communication between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the case of the example 1, the following examples are given,

as shown in fig. 1 to 3, an animal quarantine fence comprises a frame 10, a group of opposite sides of the frame 10 are fixedly provided with gates 20, animals can enter from the gate on one side during quarantine inspection, and can exit from the gate on the other side after inspection is finished; the other set of opposite sides of the frame are provided with two movable side rails 30 and two sets of rotating assemblies 40 in parallel, the rotating assemblies 40 are rotatably arranged on the frame 10, and the rotating assemblies 40 arrange the two movable side rails 30 on the frame 10, when the rotating assemblies rotate under the action of external force, the movable side rails 30 move towards the inner side of the frame 10 to further reduce the distance between the two movable side rails 30, and the accommodating space of the frame is defined as the inner side of the frame; the size of the accommodation space of the frame can be adjusted by the movement of the movable side rail 30, so that the livestock quarantine fence of the application file can be suitable for livestock of different body types.

Of course, still include locking mechanism 50 in this scheme, locking mechanism 50 is connected with rotating assembly 40, and locking mechanism 50 can lock rotating assembly 40 after the rotation, and then fixes the activity side rail 30 under this specific accommodation space, prevents that the livestock from taking place the activity at struggling in-process activity side rail 30 and losing the restriction to the livestock, and then influences follow-up quarantine inspection.

Wherein, the side of the unilateral movable side rail 30 close to the two side rail doors 20 is provided with a rotating assembly 40, that is, two sides have four groups of rotating assemblies 40, and the rotating assembly 40 comprises a first crank mechanism 41, a second crank mechanism 42 and a connecting rod mechanism 43; one end of the first crank mechanism 41 is rotatably provided on the side above the movable side rail 30; the other end is rotatably connected with the upper frame 10 and partially penetrates out of the upper frame; one end of the second crank mechanism 42 is rotatably provided on one side below the movable side rail 30, and the other end is rotatably provided on the lower frame 10; in addition, the link mechanism 43 connects the two first crank mechanisms 41 on the same movable side rail 30 to the portion penetrating out of the frame 10, so that the two first crank mechanisms 41 connected to the link mechanism 43 can rotate synchronously.

Under the condition, the movable side fence 30 on one side is pushed inwards, the first crank mechanism 41, the second crank mechanism 42 and the frame rotate, so that the movable fence door 30 moves towards the inner side of the frame 10, the accommodating space of the quarantine fence is further reduced, the quarantine fence can be better suitable for livestock with smaller body size, and the applicability of the livestock quarantine fence is improved. The link mechanism 43 is configured to enable the upper portions of the first crank mechanisms at both sides of the movable side rail 30 to rotate around the frame 10 at the same time, and certainly, the lower portion of the first crank mechanism 41 can rotate around the hinge joint with the movable side rail 30 at the same time, so as to avoid that the left and right ends of the movable side rail are not synchronized in the process of moving inwards due to uneven stress in the process of pushing the movable side rail, and further the movable side rail is inclined to cause the uncontrolled accommodating space (the left and right directions are defined as left and right directions relative to the view angle in fig. 1, that is, the direction from one side rail door to the other side rail door).

In the above technical solution, the movable side rails 30 on both sides are controlled separately, that is, the movable side rails 10 on both sides can be controlled separately when adjusting the accommodating space of the quarantine bar, in this case, two sets of locking mechanisms 50 are provided, each set of locking mechanism 50 is connected with the corresponding side link mechanism 43, and the movable side rail 30 on the side where the link mechanism is located is locked by controlling the link mechanism 43.

Certainly, the movable side fences 30 on the two sides can also be controlled to synchronously move towards the inner side of the frame 10, for example, in the present embodiment, two groups of link mechanisms 43 are connected through a link piece 44, and two ends of the link piece 44 are respectively hinged to two link mechanisms 43, so that the synchronous rotation of the four first crank mechanisms 41 on the two sides can be realized; when the movable side rail 30 on one side is pushed inwards, the upper parts of the two first crank mechanisms 41 on the same side rotate around the frame at the same time, the lower parts rotate around the hinge shafts with the movable side rail at the same time, and under the action of the linkage piece 44, the upper parts and the lower parts of the two first crank mechanisms 41 on the other movable side rail also rotate at the same time, so that the movable side rail 30 on the other side is driven to move inwards.

This synchronous movement of the movable side rails 30 can improve the efficiency of the adjustment of the accommodation space compared to a single-side control. In this case, the locking mechanism 50 is a set, the locking mechanism 50 is connected to one side link mechanism 43, when the locking mechanism 50 locks the connected link mechanism 43, the link mechanism 43 will not move or rotate any more under the action of the locking mechanism 50, and the movable side rail 30 on the side of the link mechanism 43 can be fixed. Meanwhile, the link mechanism 43 on the other side can be locked by the link 44 to fix the movable side rail on the other side, that is, the movable side rails 30 on both sides can be locked by a set of locking mechanisms 50.

In the above technical solutions, the accommodation space of the epidemic prevention fence is adjusted by pushing or pulling the movable side fence 30 at both sides inwards or outwards, and for a large epidemic prevention fence, it is hard to manually push or pull the movable side fence inwards or outwards. In order to solve the practical problem, in the present solution, as shown in fig. 2 again, a rotating rod 45 is further disposed between the opposite sides of the first crank mechanism 41 and the second crank mechanism 42 near the side fence door 20, a rotating handle 46 is fixedly connected to the rotating rod 45, and in the practical use process, the rotating handle 46 is rotated to drive the rotating rod 45, and further drive the first crank mechanism 41 and the second crank mechanism 42 on the two sides of the rotating rod 45 to rotate, so that the movable side fence 30 can move towards the inside of the frame; the movable side rail can be moved to the outside of the frame 10 by rotating the handle 46 in the opposite direction, and this adjustment increases the moment arm during the rotation by rotating the handle, so that the solution is more labor-saving and easier to operate than the method of pushing or pulling the movable side rail 30 inward or outward. To the epidemic prevention fence that is provided with linkage 44, the unilateral sets up dwang 45 and rotation handle 46 and can realize above function, of course, also can all set up dwang 45 and rotation handle 46 in the corresponding position of both sides, like this all can conveniently carry out the operation of accommodation space adjustment when the workman carries out the epidemic prevention inspection in arbitrary one side.

The link mechanism 43 functions to realize that the first crank mechanisms 42 on both sides thereof can rotate synchronously, for example, the link mechanism 43 includes two first links 431 and one second link 432, one end of each of the two first links 432 is hinged to a portion of each of the two first crank mechanisms 41 penetrating through the frame 10, and the other end of each of the two first links 431 is hinged to both ends of each of the second links 432; under the structure, the locking mechanism 50 can lock the movable side rail 30 as long as the locking mechanism 50 can lock the first connecting rod 432 or the second connecting rod 432, for example, the locking mechanism 50 is a cylinder with a telescopic shaft, the fixed end of the cylinder is hinged on the upper end surface of the frame 10, the telescopic end of the cylinder is hinged at one end of one of the first connecting rods 431 close to the second connecting rod 432, when the rotating handle 46 is rotated or the movable side rail is pushed in/pulled out to adjust the accommodation space of the epidemic prevention fence, the telescopic shaft of the cylinder is freely stretched and does not limit the movement of the first connecting rod 431, when the movable side rail 30 needs to be locked, the length of the telescopic shaft of the cylinder is controlled to be unchanged, so that the first connecting rod 431 can not move or rotate, the movable side rail can be locked, even if livestock limited in the accommodation space of the epidemic prevention fence is struggled, the movable side rails at both sides can still be firmly limited, the successful implementation of the epidemic prevention inspection process is ensured. Of course, the locking mechanism 50 may also be selected from other mechanisms capable of limiting the rotation angle of the first link 431, such as a ratchet-pawl mechanism, and the like, and is not limited to the specific structure in this embodiment.

As a preferred scheme, an adapter plate 47 is further fixed on the first connecting rod 431 where the rotating rod 45 is located, a vice rotating rod 48 is fixedly connected below the adapter plate 47, the vice rotating rod 48 is parallel to the rotating rod 45, and the other side of the vice rotating rod 48 is fixedly arranged on the rotating handle 46, in the scheme, when the rotating handle 46 is rotated, on one hand, the first crank mechanism 41 and the first connecting rod 431 can be driven to rotate through the rotating rod 45, on the other hand, the first connecting rod 431 can be driven to rotate through the vice rotating rod 48 and the adapter plate 47, compared with the scheme with only the rotating rod 45 and the rotating handle 46, the scheme is more labor-saving in the use process, an operator can easily move the movable side rail 30, so that the accommodation space of the epidemic prevention fence can be adjusted, and the operability and the convenience in use of the whole epidemic prevention fence are further improved.

In the above technical solutions, the width of the epidemic prevention fence (the width is the length from one movable side fence to the other movable side fence) can be adjusted, but the length of the epidemic prevention fence (the length is the length from one side fence door to the other side fence door) cannot be adjusted. In order to prevent the livestock from being hurt in the actual operation process, the livestock cannot be tightly clamped between the movable side rails 30 on the two sides, the distance between the movable side rails 30 on the two sides is preferably just to squeeze the livestock, and in this case, the livestock can move in the length space, so in the scheme, the frame 10 on the side where at least one movable side rail 30 is located is provided with at least one second rail door 60 in a rotatable manner, and the number of the second rail doors 60 on the side is at least one; the side of the second gate 60 far from the rotation axis is further provided with an elastic plug 61, the frame of the side of the second gate 60 is provided with an insertion hole, under normal conditions, the elastic plug 61 is inserted into the insertion hole, the second gate 60 is parallel to the movable side rail 30, and the distance of the accommodating space in the length direction is large.

The frame 10 on the opposite side of the second fence 60 is also provided with a jack, when the livestock in the epidemic prevention fence has smaller body size, the elastic plug 61 is inserted into the jack at the position, the movable space of the livestock is limited in the space enclosed by the movable side fence 30 at the two sides, the fence door 20 and the second fence 60, the distance of the accommodating space in the length direction is reduced, the livestock can be more effectively limited, and the quarantine inspection effect and efficiency are improved.

In addition, during the quarantine process, the operation is generally performed through the gaps on the movable side rail 30, the gate 20 or the second gate 60 when touching, injecting or performing other close operations. On an actual epidemic prevention fence, if the fence gap is too large, livestock cannot be effectively limited, and if the fence gap is too small, operation is inconvenient; in the scheme, at least one movable side fence 30 is rotatably provided with a third fence door 31, and the number of the third fence doors 31 on one side is at least one; the third door 31 is provided with an elastic plug 61 at a side away from the rotation axis, and the third door is provided with a jack at a corresponding position on the side frame 10. Under normal conditions, the elastic plug of the third fence 60 is inserted into the corresponding jack, the third fence 60 is kept in a closed state, when injection or other operations are needed, the third fence 60 can be opened, and an operator can stretch hands into the epidemic prevention fence to a greater extent, so that the operability of the epidemic prevention fence is improved, and the applicability of the epidemic prevention fence is improved.

Quarantine completion requires that the livestock be driven out of the gate where the head of the livestock is located. If injection or other operations have been carried out at the in-process of quarantine, the animal is owing to receive the frightening, generally hardly listen to staff's the password of driving, consequently in this scheme, again as shown in fig. 3, be provided with on the activity side fence 30 of at least one side and drive slot hole 32, the upper wall that drives slot hole 32 rotationally is provided with many spacing 33, the length of spacing 33 is greater than drives slot hole 32 along vertical length, the other end of spacing 33 is contradicted naturally and is being driven the lower wall of slot hole 32, still fixedly connected with is used for holding the rack 34 that drives the pole on the frame 10 of slot hole 32 place side of driving.

In this kind of scheme, when the quarantine is accomplished and need be driven out the livestock from the quarantine fence, will put the pole 35 of driving in rack 34 and take out, stretch into from driving slot hole 32 and drive the livestock, drive pole 35 and wipe behind first spacing 33, first spacing 33 naturally falls under the effect of gravity and contradicts on the lower wall of spacing slot hole 32, if the livestock moves back to driving pole 35 position backward, because the length of spacing 33 is greater than and drives slot hole along vertical length, consequently drive pole 35 and receive the limiting action of first spacing 33, can't retreat. In this case, the animals advance again until they exit the fence from the gate 20. Therefore, the device of the scheme can greatly improve the quarantine inspection efficiency of livestock and reduce the labor intensity of workers.

The epidemic prevention fence is in the state before use as shown in fig. 1, with the gate 20 closed, the movable side fence 30 in the home position as shown in fig. 1, and the second gate 60 also in the home position as shown in fig. 1. When it is desired to drive livestock into the epidemic prevention fence, the fence gate 20 is opened as shown in fig. 4. After the livestock enters, if the livestock is small, as shown in fig. 5, the movable side fence 30 can be moved inwards by rotating the rotating rod 45 to reduce the accommodation space of the epidemic prevention fence; if the distance in the length direction of the accommodating space needs to be reduced, the second gate 60 is rotated, and then the elastic plug 61 is inserted into the insertion hole of the frame opposite to the surface where the rotating shaft of the second gate is located, as shown in fig. 6, the accommodating space is further reduced at the moment, so that the epidemic prevention requirement of small-body livestock is met. After the epidemic prevention is finished, the livestock is driven out of the epidemic prevention fence, and then the epidemic prevention inspection of the next livestock can be carried out.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein. In addition, the technical solutions between the various embodiments can be combined with each other, but must be based on the realization of those skilled in the art; where combinations of features are mutually inconsistent or impractical, such combinations should not be considered as being absent and not within the scope of the claimed invention.
