[0003] A restraint is a tool used to safely restrain animals. It mainly prevents animals from kicking, hitting, running around, and other behaviors by limiting their range of movement, thereby ensuring the safety of both staff and animals.

[0004] Existing restraints usually include a base, two side guardrails respectively arranged on both sides of the base, a front door arranged between the front ends of the two side guardrails, and a rear door arranged between the rear ends of the two side guardrails. In the process of dairy farming, when a cow is sick and needs treatment, a restraint is needed to temporarily restrain the cow because the cow is large in size and resistant to treatment. The specific method is: open the rear door of the restraint, drive the cow into the restraint from the rear door, and then close the rear door to confine the cow within the range of the restraint. At this time, the cow can be treated accordingly. After the treatment is completed, the cow can be released from the front door. However, the above-mentioned existing restraint is not provided with a restraint mechanism for restraining the cow's head. When the veterinarian treats the cow, the cow usually uses its horns to butt people, which will pose a huge threat to the veterinarian's personal safety and seriously affect the safety of the restraint.

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention and are not intended to limit the present invention.

[0023] Embodiment A restraining frame for treating dairy cows

[0024] like Figure 1 As shown, this embodiment includes a base, a guardrail assembly fixed on the base, and a head restraint assembly provided on the guardrail assembly for limiting the movement of the cow's head.

[0025] The base includes a rectangular frame 1 and four short columns 2 fixed at the four corners of the bottom of the rectangular frame 1. A mounting base plate 3 is fixed to the bottom of each short column 2, and the mounting base plate 3 is fixed to the ground by expansion bolts.

[0026] The guardrail assembly includes two side guardrails 4 fixed to opposite sides of the base, at least two connecting rods 5 fixed between the tops of the two side guardrails 4, an openable and closable front door frame located between the front ends of the two side guardrails 4, and an openable and closable rear door frame 13 located between the rear ends of the two side guardrails 4. Specifically, in this embodiment, the side guardrails 4 include a U-shaped frame and two horizontal bars fixed to the U-shaped frame, with the open ends of the U-shaped frame fixed to corresponding positions at the top of the base. A connecting rod 5 is fixed between the tops of the front ends of the two U-shaped frames, and another connecting rod 5 is fixed between the tops of the rear ends of the two U-shaped frames. The front door frame includes a rectangular door frame 6, a mounting crossbar 7 fixed between the upper portions of the rectangular door frames 6, and two U-shaped stoppers 12 fixed to opposite sides of the rectangular door frames 6. The two U-shaped stoppers 12 are located within the rectangular door frames 6, and the restricted area formed between the two U-shaped stoppers 12 is narrow enough to accommodate the cow's neck, preventing the cow's head from protruding from this restricted area. One side of the rectangular door frame 6 is hinged to the side guardrail 4 on the right side, and the other side of the rectangular door frame 6 is detachably connected to the side guardrail 4 on the left side via a positioning member, wherein the positioning member includes a first positioning sleeve 8 fixed to the front end of the side guardrail 4 on the left side, a second positioning sleeve 9 fixed to the rectangular door frame 6 and located directly above the first positioning sleeve 8, a positioning vertical rod 10 inserted into the first and second positioning sleeves 8, 9, and a positioning handle 11 fixed to the top of the positioning vertical rod 10. One side of the rear door frame 13 is hinged to the side guardrail 4 on the right side, and the other side of the rear door frame 13 is detachably connected to the side guardrail 4 on the left side via a chain lock.

[0027] The head restraint assembly includes two rotating rods 14 rotatably connected to the front door frame. The tops of the two rotating rods 14 are hinged to the two ends of the connecting rod mechanism respectively. The connecting rod mechanism can move the tops of the two rotating rods 14 in a direction toward each other to restrain the cow's head. The connecting rod mechanism can move the tops of the two rotating rods 14 in a direction away from each other to release the restraint on the cow's head. It should be explained that when the cow's head is restrained, the cow cannot retract its head from the area between the two rotating rods 14. When the cow's head is released from the restraint, the cow can retract its head from the wider area between the upper parts of the two rotating rods 14. Specifically, in this embodiment, if Figure 3As shown, a U-shaped rod 15 is fixed to the upper end of the side surface of the rotating rod 14 near the rear door frame. The U-shaped rod 15 is sleeved on the outer side of the mounting cross bar 7 in the front door frame. The rotating rod 14 can slide on the mounting cross bar 7. The lower end of the rotating rod 14 is hinged to the U-shaped limit frame 12 in the rectangular door frame 6. The connecting rod mechanism includes a first rod 16, a second rod 17 hinged to the end of the first rod 16, a third rod 18 hinged to the end of the second rod 17, and a fourth rod 19 hinged to the end of the third rod 18. The free end of the first rod 16 is hinged to the top of the rotating rod 14 on the left side, and the free end of the fourth rod 19 is hinged to the top of the rotating rod 14 on the right side. An operating handle 23 is fixed to the second rod 17.

[0028] The guardrail assembly is equipped with a limiting member to restrict the movement of the linkage mechanism when restraining the cow's head. The limiting member includes a threaded rod 20 fixed to the top of the left-side side guardrail 4 and a limiting plate threadedly connected to the threaded rod 20. Specifically, in this embodiment, the limiting plate includes a long strip plate 21 and a hexagonal nut 22 fixed to the top of the long strip plate 21. The threaded rod 20 is threadedly connected to the long strip plate 21 and the hexagonal nut 22 and extends to the outside of the hexagonal nut 22.

[0029] When using this embodiment, before restraining a cow, the rear door frame 13 is in an open state, the tops of the two rotating rods 14 are away from each other, and the two rotating rods 14 are in an inclined state. The long strip plate 21 in the limit plate is rotated to a position that does not affect the movement of the connecting rod mechanism. When it is necessary to restrain the cow, the cow is driven from the rear door frame 13 into the space surrounded by the guardrail assembly and then the rear door frame 13 is closed. The cow's head is then extended from the wider area between the upper parts of the two rotating rods 14. At this time, the operating handle 23 is pulled downward, as shown in FIG. Figure 2 、 Figure 3 As shown, the operating handle 23 drives the linkage mechanism to move, and the linkage mechanism drives the tops of the two rotating rods 14 to move toward each other until the two rotating rods 14 are in a vertical state. Stop pulling the operating handle 23, and the cow's head cannot retract from the area between the two rotating rods 14. Then rotate the limit plate until the bottom of the limit plate contacts the top of the linkage mechanism. At this time, the limit plate blocks the linkage mechanism and prevents it from moving, thus achieving stable restraint on the cow's head. When the cow is treated and needs to be released from restraint, rotate the long strip plate 21 in the limit plate to a position that does not affect the movement of the linkage mechanism, and then push the operating handle 23 upward, as shown in FIG. Figure 1As shown, the operating handle 23 drives the linkage mechanism, which in turn drives the tops of the two rotating rods 14 to move away from each other until the area between the upper portions of the two rotating rods 14 allows the cow's head to retract. At this point, the two rotating rods 14 return to their tilted state before securing the cow. After the cow's head retracts from the area between the upper portions of the two rotating rods 14, the positioning handle 11 is held to pull the positioning vertical rod 10 out of the first positioning sleeve 8 and the second positioning sleeve 9. The front mast is then opened to release the cow. When the cow needs to be secured again, the above operation can be repeated.

[0030] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
