Description

Technical Field

[0001] The invention relates to the technical field of veterinary instruments, and in particular to a range-adjustable cow neck clamp and a use method thereof. Background Art

[0002] In the process of raising cattle, it is necessary to regularly carry out veterinary treatment activities such as routine physical examination, immunization, artificial insemination, pregnancy examination, surgical treatment, dehorning, calving, etc. During such veterinary treatment activities, in order to ensure that the cattle remain motionless, it is necessary to securely and stably fix the head and neck of the cattle through the cow neck, thereby improving the safety and accuracy of the operation. This device usually has an adjustable design to accommodate cattle of different sizes, and is equipped with protective measures to avoid causing harm to the cattle.

[0003] Before veterinary treatment of cattle, it is particularly difficult to use traditional triangular neck clamps to secure the neck of cattle because they are usually in a vigilant and uncooperative state. These neck clamps not only require a certain degree of cooperation from the cattle to ensure correct alignment, but also need to be adjusted when facing cattle of different body shapes and neck sizes. This is particularly troublesome when the cattle are unusually uncooperative, adding time and complexity to the preparation of veterinary treatment activities.

[0004] To this end, the present invention provides a range-adjustable cattle neck clamp and a use method thereof. Summary of the invention

[0005] In order to overcome the disadvantage that it is difficult to adaptively adjust and fix the cow's neck, the present invention provides a cow neck clamp with adjustable range and a use method.

[0006] A range-adjustable cattle neck clamp comprises a mounting frame, the mounting frame is slidably connected to a U-shaped frame symmetrically distributed along the mounting frame, the U-shaped frame is rotatably connected to a clamping rod, torsion springs symmetrically distributed along the clamping rod are fixedly connected between the U-shaped frame and adjacent clamping rods, the mounting frame is slidably connected to a blocking frame symmetrically distributed along the mounting frame, the blocking frame is used to block the clamping rod on the same side, a spring is fixedly connected between the blocking frame and adjacent mounting frames, a pressure frame is slidably connected between the symmetrically distributed blocking frames, the blocking frame is slidably connected to a guide plate symmetrically distributed along the blocking frame, the guide plate is slidably connected to the mounting frame, the guide plate is provided with an oblique groove, the U-shaped frame is slidably connected to a clamping rod symmetrically distributed along the U-shaped frame, the guide plate is extruded and matched with the adjacent clamping rod through the oblique groove, and the U-shaped frame is provided with continuously arranged clamping holes.

[0007] Optionally, it also includes a card frame symmetrically distributed along the mounting frame, the card frame is slidably connected to the mounting frame, the card frame has wedge-shaped surfaces symmetrically distributed along the card frame, the wedge-shaped surfaces of the card frame are squeezed and matched with the U-shaped frame on the same side, and a first tension spring symmetrically distributed along the card frame is fixedly connected between the mounting frame and the card frame.

[0008] Optionally, the card rack will move only when all the U-shaped racks squeeze the card rack together.

[0009] Optionally, it also includes fixing rods symmetrically distributed along the mounting frame, the fixing rods are fixedly connected to the mounting frame, L-shaped clamping plates are slidably connected between adjacent fixing rods, the clamping rods contact the adjacent L-shaped clamping plates during the process of being pulled out of the clamping holes, a second tension spring is fixedly connected between the L-shaped clamping plates and the mounting frame, and the U-shaped frame is fixedly connected to racks symmetrically distributed along the U-shaped frame.

[0010] Optionally, the L-shaped clamping plate is extrusion-fitted with adjacent racks.

[0011] Optionally, a missing gear corresponding to the clamping rod is further included, the missing gear is fixedly connected to the corresponding clamping rod, and the two missing gears are meshed with each other.

[0012] Optionally, a baffle rod corresponding to the missing gear is also included, the baffle rod is slidingly connected to the adjacent missing gear, a third tension spring is fixed between the missing gear and the adjacent baffle rod, and a fan-shaped block is fixed to one side of the U-shaped frame close to the adjacent baffle rod, and the block is used to slow down the adjacent baffle rod.

[0013] Optionally, one end of the blocking rod close to the adjacent blocking block is configured as a spherical surface, and the blocking rod is extruded and fitted with the adjacent blocking block through the spherical surface.

[0014] A method for using a range-adjustable cattle neck clamp comprises the following steps: S1: The cow stretches its neck between the left and right clamps; S2: Press the pressure frame downward so that the blocking frame no longer blocks the clamping rods, and the two clamping rods swing to a vertical state parallel to each other; S3: Loosen the pressing frame so that the two vertical clamping rods are located between the two blocking frames, and the clamping rods firmly clamp the cow's neck.

[0015] Compared with the prior art, the present invention has the following advantages: The present invention uses two opened clamping rods to facilitate the cow to put its neck between the two clamping rods, and then step on the pressure frame to automatically adjust the distance between the two clamping rods according to the size of the cow's neck. Finally, the clamping rods are automatically fixed by loosening the pressure frame. The operation is simple, convenient and practical.

[0016] The present invention arranges a clamping frame so that when only one side of the clamping rod is stressed, the clamping rods and the U-shaped frames on both sides cannot move outwards. Only when the clamping rods on both sides are stressed so that the U-shaped frames on both sides are forced to open outwards, can the clamping frame be squeezed open. In this way, it is possible to quickly find that the cow's neck is too biased towards the clamping rod on one side. At this time, the cow's neck needs to be moved toward the middle to effectively fix the cow's neck.

[0017] The present invention uses an L-shaped clamping plate and a rack for extrusion matching, so that the U-shaped frame adapted to the cow's neck being opened is squeezed outward and continues to open a short distance, so that the cow's neck is in a loose clamping environment, thereby improving the cow's comfort.

[0018] The present invention provides a missing gear so that after the two U-shaped frames are pushed inward to reset, only one clamping rod needs to be pushed to rotate outward to simultaneously cause the other clamping rod to rotate outward, thereby saving time and effort.

[0019] The present invention slows down the blocking rod by means of a blocking block, so as to achieve the effect of slowing down the clamping rod, thereby preventing the clamping rod from rebounding too quickly and hurting the cow when the torsion spring rebounds and drives the clamping rod to swing toward the middle to contact the cow's neck when the foot steps down on the pressure frame, causing the cow to be frightened.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: A range-adjustable cattle neck clamp, such as Figure 1-Figure 3 As shown, it includes a mounting frame 1, the mounting frame 1 is slidably connected to a U-shaped frame 2 symmetrically distributed along the mounting frame 1 along the left and right directions, the upper part of the U-shaped frame 2 is rotatably connected to a clamping rod 3, the two clamping rods 3 are initially distributed in an "eight" shape, which is convenient for the cow to extend its neck between the two clamping rods 3, and a torsion spring 4 symmetrically distributed along the clamping rod 3 is fixed between the U-shaped frame 2 and the adjacent clamping rods 3, and the mounting frame 1 is slidably connected to a blocking frame 5 symmetrically distributed along the mounting frame 1 along the left and right directions, and the blocking frame 5 is used to block the clamping rod 3 on the same side, and the blocking frame 5 and the adjacent mounting frame 1 is fixed with a spring 6, a pressing frame 7 is slidably connected between the lower parts of the left-right symmetrically distributed blocking frames 5, a guide plate 8 symmetrically distributed along the front and back of the blocking frame 5 is slidably connected to the outer side of the blocking frame 5, the guide plate 8 slides up and down along the mounting frame 1, an oblique groove is opened on the upper part of the guide plate 8, the middle of the U-shaped frame 2 is slidably connected with a clamping rod 9 symmetrically distributed along the front and back of the U-shaped frame 2, the guide plate 8 is squeezed and matched with the adjacent clamping rod 9 through the oblique groove, and eight continuously arranged clamping holes 901 are opened in the middle of the U-shaped frame 2 from left to right, and the clamping rod 9 is inserted into one of the clamping holes 901.

[0032] When veterinary treatment is required, the cow first extends its neck between the left and right clamping rods 3, and then steps on the pressure frame 7. The pressure frame 7 drives the blocking frame 5 to move downward, and the spring 6 is compressed, so that the blocking frame 5 no longer blocks the clamping rod 3. In this process, the blocking frame 5 drives the guide plate 8 to slide downward, and the guide plate 8 then squeezes the clamping rod 9 through the inclined groove to move it away from the clamping hole 901, thereby releasing the limit on the U-shaped frame 2. At this time, the torsion spring 4 rebounds and drives the clamping rod 3 to swing toward the middle until it contacts the cow's neck. If the torsion spring 4 is not fully reset at this time, the torsion spring 4 continues to rebound, causing the U-shaped frame 2 to slide horizontally outward along the mounting frame 1. The U-shaped frame 2 drives the blocking frame 5 to slide outward along the pressure frame 7 through the spring 6 until the torsion spring 4 is fully reset. At this time, the two clamping rods 3 swing When the cow is in a vertical state parallel to each other, the pressure frame 7 is released again, and the spring 6 is reset to drive the blocking frame 5 to slide upward. The two vertical clamping rods 3 are located between the two blocking frames 5. The blocking frame 5 limits the clamping rod 3 so that the clamping rod 3 fixes the cow's neck. At the same time, the blocking frame 5 drives the guide plate 8 to slide upward, and the guide plate 8 then moves the clamping rod 9 through the inclined groove to insert into the corresponding clamping hole 901, thereby limiting and fixing the U-shaped frame 2. In this way, the present invention uses two opened clamping rods 3 to facilitate the cow to extend its neck between the two clamping rods 3, and then by stepping on the pressure frame 7, the distance between the two clamping rods 3 can be automatically adjusted according to the size of the cow's neck. Finally, by releasing the pressure frame 7, the clamping rod 3 is automatically fixed. The operation is simple, convenient and practical.

[0033] When the veterinary treatment is completed, the pressure frame 7 is stepped down again, so that the blocking frame 5 moves downward until it no longer blocks the clamping rod 3, and then the two U-shaped frames 2 are pushed inward to reset, and then the two clamping rods 3 are rotated outward, the torsion spring 4 is deformed, and then the pressure frame 7 is released, so that the blocking frame 5 moves upward until it blocks the clamping rod 3 again, thereby restoring the initial state.

[0034] Embodiment 2: Based on embodiment 1, Figure 4 As shown, it also includes a bracket 10 symmetrically distributed along the upper and lower parts of the mounting frame 1. The bracket 10 is slidably connected to the mounting frame 1. The bracket 10 has wedge-shaped surfaces symmetrically distributed along the left and right parts of the bracket 10. The wedge-shaped surfaces of the bracket 10 are squeezed and matched with the U-shaped frame 2 on the same side. When the left and right U-shaped frames 2 squeeze the bracket 10 outward together, the upper bracket 10 will move upward, and the lower bracket 10 will move downward. A first tension spring 11 symmetrically distributed along the left and right parts of the bracket 10 is fixedly connected between the mounting frame 1 and the bracket 10.

[0035] If the cow's neck is too biased towards the clamping rod 3 on one side, only the clamping rod 3 and the U-shaped frame 2 on that side move outward, while the clamping rod 3 on the other side does not contact the cow's neck when it swings inward to a vertical state, a gap will be left between the cow's neck and the clamping rod 3 on the other side, and the cow's neck cannot be effectively fixed. To avoid this situation, a clamping frame 10 is set so that when only the clamping rod 3 on one side is subjected to force, the clamping rods 3 and the U-shaped frame 2 on both sides cannot move outward. Only when the clamping rods 3 on both sides are subjected to force, so that the U-shaped frames 2 on both sides are forced to open outward, can the clamping frame 10 be squeezed open and the first tension spring 11 be stretched. In this way, it can be quickly discovered that the cow's neck is too biased towards the clamping rod 3 on one side. At this time, the cow's neck needs to be moved toward the middle to achieve effective fixation of the cow's neck.

[0036] Embodiment 3: Based on embodiment 2, Figure 5 and Figure 6 As shown, it also includes a fixing rod 12 symmetrically distributed along the mounting frame 1, the fixing rod 12 is fixedly connected to the mounting frame 1, and there are eight fixing rods 12 in total. An L-shaped card plate 13 is slidably connected between two adjacent fixing rods 12. When the card rod 9 is pulled out of the card hole 901, it will contact the adjacent L-shaped card plate 13. A second tension spring 14 is fixedly connected between the L-shaped card plate 13 and the mounting frame 1, and a rack 15 symmetrically distributed along the front and back of the U-shaped frame 2 is fixedly connected to one side of the U-shaped frame 2 close to the card hole 901. After the card rod 9 contacts the adjacent L-shaped card plate 13, the L-shaped card plate 13 is pushed to slide along the fixing rod 12 until it is separated from the adjacent rack 15. The L-shaped card plate 13 is reset by the second tension spring 14 and will contact the tooth surface of the adjacent rack 15 and be squeezed and fit during the reset process of the card rod 9.

[0037] When the U-shaped frame 2 is squeezed outward by the cow's neck, the U-shaped frame 2 drives the clamping hole 901 to move outward synchronously. When the clamping hole 901 stops moving, if the clamping rod 9 is facing between two adjacent clamping holes 901 and is biased toward the outer clamping hole 901, when the clamping rod 9 moves to reset, the clamping rod 9 will be inserted into the clamping hole 901 biased toward the outer side, causing the U-shaped frame 2 to be squeezed inward by the clamping rod 9 after the cow's neck is opened to retreat a short distance, thereby causing the cow's neck to be in a tight clamping environment, which may cause the cow's neck to be stuck, affecting the cow's comfort. To this end, the following operations are required so that in this case, the U-shaped frame 2 that adapts to the cow's neck opening is squeezed outward and continues to open a short distance, so that the cow's neck is in a loose clamping environment. Specifically: When the clamping rod 9 moves out of the clamping hole 901, it contacts the adjacent L-shaped clamping plate 13 and pushes the L-shaped clamping plate 13 to slide relative to the fixing rod 12 toward the side of the stretched second tension spring 14, so that the L-shaped clamping plate 13 is separated from the rack 15; When the clamping rod 9 moves in the opposite direction and is inserted into the clamping hole 901, the second tension spring 14 gradually rebounds, so that the L-shaped clamping plate 13 moves synchronously with the clamping rod 9, and the L-shaped clamping plate 13 contacts the tooth surface of the rack 15. If the L-shaped clamping plate 13 contacts the leftmost side of each tooth surface of the rack 15, the clamping rod 9 is facing a clamping hole 901, and then the clamping rod 9 is inserted into the facing clamping hole 901. If the L-shaped clamping plate 13 is not in contact with the leftmost side of each tooth surface of the rack 15, the L-shaped clamping plate 13 squeezes the rack 15 to move outward, so that the clamping hole 901 moves outward, until the L-shaped clamping plate 13 contacts the leftmost side of the tooth surface of this section of the rack 15, and then the clamping rod 9 is inserted into the facing clamping hole 901.

[0038] Embodiment 4: Based on embodiment 3, Figure 7 As shown, it also includes a missing gear 16 corresponding to the clamping rod 3. The missing gear 16 is fixedly connected to the corresponding clamping rod 3, and the two missing gears 16 are meshed with each other. By setting the missing gear 16, after the two U-shaped frames 2 are pushed inward to reset, only one clamping rod 3 needs to be pushed outward to rotate the other clamping rod 3 at the same time, which saves time and effort.

[0039] like Figure 8 and Fig. 9 As shown, it also includes a baffle rod 17 corresponding to the missing gear 16, the baffle rod 17 is slidably connected to the adjacent missing gear 16, a third tension spring 18 is fixedly connected between the missing gear 16 and the adjacent baffle rod 17, and four fan-shaped blocks 19 are fixedly connected to one side of the U-shaped frame 2 close to the adjacent baffle rod 17, the block 19 is used to slow down the adjacent baffle rod 17, and one end of the baffle rod 17 close to the adjacent block 19 is set as a spherical surface, and the baffle rod 17 is squeezed and matched with the adjacent block 19 through the spherical surface.

[0040] In order to prevent the clamp rod 3 from rebounding too quickly and hurting the cow when the torsion spring 4 rebounds and drives the clamp rod 3 to swing toward the middle and contact the cow's neck when the foot steps down on the pressure frame 7, causing the cow to be frightened, it is necessary to slow down the rebound speed of the clamp rod 3. Specifically, the block 19 is used to slow down the block rod 17. During this process, the third tension spring 18 is adaptively stretched and reset, thereby slowing down the missing gear 16, and then slowing down the clamp rod 3.

[0041] Embodiment 5: Based on Embodiment 4, a method for using a range-adjustable cattle neck clamp comprises the following steps: S1: The cow stretches its neck between the left and right clamping bars 3; S2: stepping down the pressing frame 7, so that the blocking frame 5 no longer blocks the clamping rod 3, and the two clamping rods 3 swing to a vertical state parallel to each other; S3: Release the pressing frame 7, so that the two vertical clamping rods 3 are located between the two blocking frames 5, and the clamping rods 3 fix the cow's neck.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
