[0002] The cattle neck yoke is convenient for fixing dairy cows and can be flexibly opened and closed when the dairy cows lower their heads to feed, facilitating activities such as routine physical examinations, immunizations, artificial inseminations, pregnancies, treatments, dehorning, calving, etc. for veterinarians or breeders, reducing labor intensity and improving work efficiency.

[0003] When cattle are eating, they need to put their heads between two clamping rods, and then personnel need to erect the two clamping rods one by one to restrict the cattle's heads to ensure that the cattle do not wander around and fight during eating. However, the erection of the two clamping rods during this process requires a large amount of time for personnel to operate. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a cattle neck yoke, which has the advantages of all clamping rods can be erected and lifted with one operation, and solves the above problems.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A cattle neck yoke, including a lower frame and an upper frame. Sealing plates are detachably installed at both ends of the lower frame and the upper frame. A vertical frame is fixedly installed between the lower frame and the upper frame. One end of a cross frame is fixedly installed in the middle section of the vertical frame. The other end of the cross frame is hinged with a clamping rod. A limiting rod is fixedly installed on the side surface of the clamping rod. A clamping seat is fixedly installed at the top of the clamping rod. A locking rod is inserted into the clamping seat. A support is fixedly installed at the top of the upper frame. A cross bar is rotatably installed in the support. A handle is movably installed at the tail end of the cross bar. A lock head corresponding to the locking rod is hinged on the outer side of the cross bar. Arc-shaped holes are opened on the front and back of the upper frame. A sliding rod is inserted into the arc-shaped hole. The sliding rod is fixedly installed on the inner wall of the support.

[0006] Preferably, a convex strip is fixedly installed on the inner wall of the upper frame. Two staggered racks are slidably installed inside the upper frame. Grooves corresponding to the convex strip are opened on the surface of the racks. The racks slide inside the upper frame through the convex strip and the grooves.

[0007] Preferably, a shaft rod is fixedly installed on the inner wall of the upper frame. The top of the shaft rod extends upward outside the upper frame. A gear meshing with the rack is rotatably installed on the outer side of the shaft rod. The gear is located between the two staggered racks. Two groups of limiting strips are fixedly installed on the back of the rack. The number of each group of limiting strips is two. One end of the sliding rod penetrates through the arc-shaped hole and extends between the two limiting strips.

[0008] Preferably, one end of the rack is fixedly installed with an extension rod, the other end of the extension rod penetrates and extends to the outside of the sealing plate, a circular groove and a deep groove are formed at the other end of the rack, the circular groove and the deep groove communicate with each other, and the diameter of the deep groove is smaller than that of the circular groove.

[0009] Preferably, a long rod is inserted into the deep groove, a spring is sleeved on the outside of the long rod, a tail seat is fixedly installed at the tail end of the long rod, and the tail seat is detachably installed inside the upper frame through screws.

[0010] Preferably, one end of the spring abuts against the inside of the circular groove, and the other end of the spring abuts against the surface of the tail seat.

[0011] Preferably, sliding grooves corresponding to the convex strips are formed at the top and bottom of the tail seat, and the tail seat slides inside the upper frame through the sliding grooves and the convex strips.

[0012] Compared with the prior art, the utility model has the following beneficial effects: By pushing the extension rod on one side to slide, the rack then slides in the upper frame. At the same time, the rack drives another rack to slide through the middle gear, and the two racks close at the same time. The other end of the rack will compress the spring. While the rack slides, the limiting strip can drive the sliding rod to slide in the arc-shaped hole. Then the clamping seat, the clamping rod and the locking rod all rotate around the hinge point of the clamping rod and the cross frame. The rotation of the locking rod squeezes the lock head, and the lock head rotates around its own hinge point. After the locking rod passes over the lock head, the lock head drops under its own weight, and the bottom of the lock head blocks the reverse rotation and return of the locking rod. In this process, by pushing the extension rod on one side, multiple clamping rods can be rotated and erected, and there is no need for personnel to straighten the clamping rods one by one; By driving the cross bar to rotate through the handle, the cross bar drives the lock head to rotate, and the lock head no longer blocks the locking rod. Then before the spring restores its deformation, the spring will push the rack to slide sideways. The rack drives another rack to slide synchronously through the gear. When sliding outwards synchronously, the rack pushes the sliding rod to slide in the arc-shaped hole through the limiting strip. Then the clamping rod will rotate from vertical to inclined, and the clamping rod no longer restricts the bull head. The bull can move again. In this process, the rotation and return of the clamping rod can also be completed by operating on one side, thus improving efficiency and achieving the purpose of saving time and effort.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-2 , a cattle neck yoke, including a lower frame 1 and an upper frame 2. The interiors of the lower frame 1 and the upper frame 2 are both hollow to reduce weight. Sealing plates 3 are detachably installed at both ends of the lower frame 1 and the upper frame 2 to prevent rainwater from entering from both ends. A vertical frame 4 is fixedly installed between the lower frame 1 and the upper frame 2. One end of a horizontal frame 5 is fixedly installed in the middle section of the vertical frame 4. The other end of the horizontal frame 5 is hinged with a clamping rod 6. The cross-section of the clamping rod 6 is circular, and the bottom of the clamping rod 6 is inclined. A limiting rod 7 is fixedly installed on the side of the clamping rod 6 to ensure that when the clamping rod 6 is erected, the limiting rod 7 just abuts against the bottom of the horizontal frame 5. A clamping seat 8 is fixedly installed at the top of the clamping rod 6, and a locking rod 9 is inserted into the interior of the clamping seat 8.

[0024] Please refer to Figure 3-4, a support 10 is fixedly installed at the top of the upper frame 2. A cross bar 11 is rotatably installed inside the support 10. A handle 12 is movably installed at the tail end of the cross bar 11. A lock head 13 corresponding to the lock rod 9 is hinged to the outer side of the cross bar 11. When the clamping bar 6 is erected, the lock rod 9 squeezes the bottom of the lock head 13. The bottom of the lock head 13 rotates and tilts up. When the lock rod 9 crosses the bottom of the lock head 13, the lock head 13 drops due to gravity, and the lock head 13 blocks the lock rod 9 from returning to its original position.

[0025] Please refer to Figure 3-4 , arc-shaped holes 14 are formed in both the front and back of the upper frame 2. A sliding rod 15 is inserted into the arc-shaped holes 14, and the sliding rod 15 is fixedly installed on the inner wall of the support 10. The clamping bar 6 changes from an inclined state to a vertical state, and the sliding rod 15 slides from one end of the arc-shaped hole 14 to the other end.

[0026] Please refer to Figure 5-6 , a rib 16 is fixedly installed on the inner wall of the upper frame 2. Two staggered racks 17 are slidably installed inside the upper frame 2. Grooves 18 corresponding to the ribs 16 are formed on the surfaces of the racks 17. The racks 17 slide inside the upper frame 2 through the ribs 16 and the grooves 18.

[0027] Please refer to Figure 7-8 , a shaft rod 19 is fixedly installed on the inner wall of the upper frame 2. The top of the shaft rod 19 extends upward to the outside of the upper frame 2. A gear 20 meshing with the rack 17 is rotatably installed on the outer side of the shaft rod 19. The gear 20 is located between the two staggered racks 17. Two groups of limiting strips 21 are fixedly installed on the back of the rack 17. The number of each group of limiting strips 21 is two. One end of the sliding rod 15 penetrates through the arc-shaped hole 14 and extends between the two limiting strips 21. When one of the racks 17 slides inside the upper frame 2, the rack 17 pushes the gear 20 to rotate, and the gear 20 drives the other rack 17 to slide, thereby ensuring that when one rack 17 is pushed, the other rack 17 can also slide synchronously.

[0028] Please refer to Figure 7-8 , an extension rod 22 is fixedly installed at one end of the rack 17. The other end of the extension rod 22 penetrates through and extends to the outside of the sealing plate 3. A circular groove 23 and a deep groove 24 are formed at the other end of the rack 17. The circular groove 23 and the deep groove 24 communicate with each other, and the diameter of the deep groove 24 is smaller than that of the circular groove 23.

[0029] Please refer to Figure 7-8, a long rod 25 is inserted inside the deep groove 24, a spring 26 is sleeved outside the long rod 25, a tail seat 27 is fixedly installed at the tail end of the long rod 25, and the tail seat 27 is detachably installed inside the upper frame 2 by screws. One end of the spring 26 abuts inside the circular groove 23, and the other end of the spring 26 abuts on the surface of the tail seat 27. Sliding grooves corresponding to the convex strips 16 are provided at both the top and the bottom of the tail seat 27, and the tail seat 27 slides inside the upper frame 2 through the sliding grooves and the convex strips 16.

[0030] During use, by pushing the extension rod 22 on one side to slide, the rack 17 then slides in the upper frame 2. At the same time, the rack 17 drives another rack 17 to slide through the middle gear 20. The two racks 17 are simultaneously retracted, and the other end of the rack 17 will compress the spring 26. While the rack 17 slides, the limiting strip 21 can drive the sliding rod 15 to slide in the arc-shaped hole 14. Then, the clamping seat 8, the clamping rod 6 and the locking rod 9 all rotate around the hinge point of the clamping rod 6 and the cross frame 5 as the center. The rotation of the locking rod 9 squeezes the lock head 13, and the lock head 13 rotates around its own hinge point. After the locking rod 9 passes over the lock head 13, the lock head 13 drops due to its own weight, and the bottom of the lock head 13 blocks the locking rod 9 from reversing and returning to its original position. In this process, by pushing the extension rod 22 on one side, multiple clamping rods 6 can be rotated and erected, without the need for personnel to straighten the clamping rods one by one. By driving the cross bar 11 to rotate through the handle 12, the cross bar 11 drives the lock head 13 to rotate, and the lock head 13 no longer blocks the locking rod 9. Then, before the spring 26 resumes deformation, the spring 26 will push the rack 17 to slide sideways. The rack 17 drives another rack 17 to slide synchronously through the gear 20. When the racks 17 slide outwards synchronously, the limiting strip 21 pushes the sliding rod 15 to slide in the arc-shaped hole 14. Then, the clamping rod 6 will rotate from the vertical to the inclined position, and the clamping rod 6 no longer restricts the bull head. The bull can walk again. In this process, the rotation and return of the clamping rod 6 can also be completed by operating on one side, thus improving the efficiency and achieving the purpose of saving time and effort.
