Description

Technical Field

[0001] This utility model relates to the field of veterinary instrument technology, and in particular to a bovine oral dilator. Background Technology

[0002] The purpose and significance of a bovine oral dilator is to effectively open the bovine mouth, facilitating veterinarians to examine, treat, and perform surgical procedures on the mouth, teeth, and throat, such as treating oral inflammation and extracting diseased teeth. It also helps keep the mouth open during medication and force-feeding, ensuring smooth procedures, reducing stress and harm to the cattle, and protecting their health and productivity.

[0003] A bovine oral dilator works by having the cow bite down on a ring-shaped device with a defined opening. External force is applied to open the cow's mouth to a certain extent, facilitating procedures. It is commonly used in veterinary clinical practice, such as examining oral diseases, treating dental problems, and removing foreign objects. It is also used in livestock farming for administering medication and cleaning the mouth, offering ease of use and ensuring the health of the cattle.

[0004] In existing technologies, some bovine oral dilators mainly expand the bovine's oral cavity by having the bovine bite on a ring with a certain opening. This can lead to the inability to adjust the bovine's oral cavity to a suitable opening, making it difficult to accurately deliver drugs or special feed into the bovine's oral cavity, affecting drug absorption and nutrient intake, and thus affecting the bovine's recovery and growth. Therefore, a bovine oral dilator is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bovine oral dilator, which aims to improve the problem that some existing bovine oral dilators mainly expand the bovine's oral cavity by having the bovine bite on a ring with a certain opening, which leads to the inability to adjust the bovine's oral cavity to a suitable opening.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bovine oral dilator includes an occlusal plate. Two upper rotating rods are rotatably connected to the bottom of the occlusal plate. Adjusting blocks are rotatably connected to the other ends of the two upper rotating rods. Lower rotating rods are rotatably connected to the bottom of the two adjusting blocks. Another upper rotating rod is rotatably connected to the other ends of the two lower rotating rods. Two sliding rods are slidably connected to the inner wall of the occlusal plate. Fixing blocks are fixedly connected to the bottom of the two sliding rods. A fixing component for fixing the dilator to the head of a cow is installed on the outer wall of the occlusal plate.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes an adjustment belt, one end of which is fixedly connected to a connecting belt, the other end of which is fixedly connected to the outer wall of the bite plate, and the other end of the bite plate is fixedly connected to a neck strap;

[0010] As a further description of the above technical solution:

[0011] One end of the neck strap is fixedly connected to a lever, and one end of the lever is fixedly connected to a ratchet.

[0012] As a further description of the above technical solution:

[0013] The other end of the lever is rotatably connected to a fixed box, and the outer wall of the ratchet is rotatably connected to the inner wall of the fixed box;

[0014] As a further description of the above technical solution:

[0015] The inner wall of the fixed box is rotatably connected to a rotating column, and the outer wall of the rotating column is fixedly connected to a pawl.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the rotating column is fitted with a torsion spring, and the other end of the rotating column is fixedly connected to a control rod;

[0018] As a further description of the above technical solution:

[0019] One end of the torsion spring is fixedly connected to the outer wall of the pawl, and the other end of the torsion spring is fixedly connected to the inner wall of the fixing box.

[0020] As a further description of the above technical solution:

[0021] The other end of the neck strap is fixedly connected to the outer wall of the fixed box. The inner wall of the fixed block is threaded with a bidirectional threaded rod. The outer wall of the bidirectional threaded rod is threadedly connected to the inner wall of the adjusting block. The inner wall of the bidirectional threaded rod is fixedly connected with a rotating handle.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the cow bites the upper and lower bite plates. At this time, the handle is rotated. The rotation of the handle causes the double-threaded rod to rotate. The rotation of the double-threaded rod causes the two adjusting blocks on the outer wall of the double-threaded rod to move in opposite directions. The movement of the adjusting blocks causes the upper and lower rotating rods to rotate, thereby causing the upper and lower bite plates to open. This allows the bite plates to open the cow's mouth, thus achieving the opening of the cow's oral cavity and adjusting the degree of opening of the cow's oral cavity.

[0024] 2. In this utility model, when it is necessary to bring the expander to the neck of the cow, the neck strap is put on the neck of the cow, and then the control lever is rotated. The rotation of the control lever drives the winch to rotate, and the rotation of the winch drives the ratchet to rotate. The rotation of the winch tightens the neck strap, thereby realizing the tightening of the neck strap. By tightening the neck strap, the loop of the neck strap is changed to adapt to the necks of different cows. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a bovine oral dilator, including a biting plate 1, which is a basic component for the bovine to bite on to achieve oral dilation. Two upper rotating rods 12 are rotatably connected to the bottom of the biting plate 1. The upper rotating rods 12 can rotate at the bottom of the biting plate 1, thereby transmitting power and changing the direction of force during adjustment. Adjusting blocks 15 are rotatably connected to the other ends of the two upper rotating rods 12. The adjusting blocks 15 are used to connect to the upper rotating rods 12 and can move with the rotation of the bidirectional threaded rod 18, thereby driving the upper rotating rods 12 to rotate. Lower rotating rods 16 are rotatably connected to the bottom of the two adjusting blocks 15. The lower rotating rods 16 are rotatably connected to the adjusting blocks 15 and can rotate when the adjusting blocks 15 move, thereby pushing the other upper rotating rod 12 to rotate. The other ends of the two lower rotating rods 16 are rotatably connected to the other upper rotating rod 12.

[0033] Another upper rotating rod 12 is rotatably connected to the lower rotating rod 16. During rotation, it cooperates with the lower rotating rod 16 to allow the two upper and lower occlusal plates 1 to open. Two sliding rods 13 are slidably connected to the inner wall of the occlusal plate 1. The function of the sliding rods 13 is to facilitate the longitudinal sliding of the two occlusal plates 1 on their surface, providing guidance and support for the movement of the occlusal plates 1. The bottom of each of the two sliding rods 13 is fixedly connected to a fixing block 14. The fixing block 14 is used to fix and limit the sliding rod 13 to ensure the stability of the sliding rod 13. The outer wall of the occlusal plate 1 is equipped with a fixing component for fixing the expander to the cow's head. The fixing component can stably fix the expander to the cow's head, which is convenient for expanding the cow's oral cavity. The bottom of the occlusal plate 1 is rotatably connected to two upper rotating rods 12. The rotational connection of the upper rotating rods 12 allows them to move within a certain range, providing the possibility of adjusting the opening degree of the occlusal plate 1.

[0034] The other ends of both upper rotating rods 12 are rotatably connected to adjusting blocks 15. The rotatable connection between the adjusting blocks 15 and the upper rotating rods 12 ensures that the upper rotating rods 12 can rotate when the adjusting blocks 15 move. The bottoms of both adjusting blocks 15 are rotatably connected to lower rotating rods 16. The rotatable connection between the lower rotating rods 16 and the adjusting blocks 15 allows the lower rotating rods 16 to rotate as the adjusting blocks 15 move, thereby driving the other upper rotating rod 12. The other ends of both lower rotating rods 16 are rotatably connected to another upper rotating rod 12. The rotatable connection between the other upper rotating rod 12 and the lower rotating rod 16 allows force to be transmitted to the other bit. On the occlusal plate 1, the opening of the occlusal plate 1 is achieved. Two sliding rods 13 are slidably connected to the inner wall of the occlusal plate 1. The sliding rods 13 are slidably connected to the inner wall of the occlusal plate 1, so that the occlusal plate 1 can slide along the sliding rods 13 to achieve opening and closing. The bottom of each of the two sliding rods 13 is fixedly connected to a fixing block 14. The fixing block 14 is fixedly connected to the bottom of the sliding rod 13 to ensure that the position of the sliding rod 13 is fixed during the working process. The outer wall of the occlusal plate 1 is equipped with a fixing component for fixing the expander to the cow's head. The fixing component is installed on the outer wall of the occlusal plate 1 and can connect the expander to the cow's head to achieve the expansion of the cow's oral cavity.

[0035] Reference Figures 2 to 4 The fixing component includes an adjusting belt 2, which is used to adjust the length of the fixing component to adapt to different cattle conditions. One end of the adjusting belt 2 is fixedly connected to a connecting belt 8, which connects the adjusting belt 2 and the bite plate 1. The other end of the connecting belt 8 is fixedly connected to the outer wall of the bite plate 1, ensuring a stable connection between the adjusting belt 2 and the bite plate 1. The other end of the bite plate 1 is fixedly connected to a neck strap, which is used to put around the neck of the cattle and fix the expander to the head of the cattle. One end of the neck strap is fixedly connected to a lever 9, which is used to rotate to tighten the neck strap and achieve the tightening of the neck strap. One end of the lever 9 is fixedly connected to a ratchet 10, which is fixedly connected to the lever 9 and can rotate with the rotation of the lever 9. The other end of the lever 9 is rotatably connected to a fixing box 3 (neck strap 4), which supports the lever 9 and allows the lever 9 to rotate stably.

[0036] The outer wall of the ratchet 10 is rotatably connected to the inner wall of the neck belt 4 of the fixed box 3. The ratchet 10 rotates within the neck belt 4 of the fixed box 3, ensuring the stability of the ratchet 10's rotation. A rotating post 6 is rotatably connected to the inner wall of the neck belt 4 of the fixed box 3. The rotating post 6 can rotate within the neck belt 4 of the fixed box 3, providing conditions for the rotation of the pawl 7. The outer wall of the rotating post 6 is fixedly connected to the pawl 7, which is fixed to the outer wall of the rotating post 6. When the rotating post 6 rotates, it can limit and engage the ratchet 10. A torsion spring 5 is sleeved on the outer wall of the rotating post 6. The outer wall of the rotating column 6 is used to drive the pawl 7 to reset. The other end of the rotating column 6 is fixedly connected to a control rod 11, which is used to control the rotation of the rotating column 6, thereby controlling the pawl 7 to limit the ratchet 10. One end of the torsion spring 5 is fixedly connected to the outer wall of the pawl 7. This end of the torsion spring 5 is connected to the pawl 7 and can drive the pawl 7 to rotate. The other end of the torsion spring 5 is fixedly connected to the neck belt of the fixed box 3. The inner wall of the fixed box 3 provides a fixing point for the torsion spring 5, so that it can play the role of driving the pawl 7 to reset.

[0037] Working principle: When it is necessary to use a dilator to dilate the cow's mouth, the cow bites the upper and lower bite plates 1. Then, the handle 17 is turned. The rotation of the handle 17 causes the double-threaded rod 18 to rotate. The rotation of the double-threaded rod 18 causes the two adjusting blocks 15 on the outer wall of the double-threaded rod 18 to move in opposite directions. The movement of the adjusting blocks 15 causes the upper rotating rod 12 and the lower rotating rod 16 to rotate, thereby opening the upper and lower bite plates 1. This allows the bite plates 1 to open the cow's mouth, thus achieving the opening of the cow's mouth. This allows for adjustment of the opening degree of the cow's mouth, making it easier for veterinarians to examine the cow's mouth. The sliding rod 13 facilitates the longitudinal sliding of the two bite plates 1 on its surface. The fixing block 14 is used to fix and limit the sliding rod 13.

[0038] When it is necessary to bring the spreader to the cow's neck, the neck strap is put around the cow's neck. Then, the control lever 11 is rotated. The rotation of the control lever 11 drives the winch 9 to rotate, which in turn drives the ratchet 10 to rotate. The rotation of the winch 9 tightens the neck strap, thereby achieving the tightening of the neck strap. By tightening the neck strap, the loop of the neck strap can be changed to adapt to different cows' necks. When the ratchet 10 rotates, the pawl 7 will engage with the ratchet 10 to limit its movement. The torsion spring 5 facilitates the reset of the pawl 7, and the rotating column 6 facilitates the rotation of the pawl 7.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
