Description

Technical Field

[0001] The present invention relates to the technical field of animal husbandry oral care, and particularly to an animal husbandry oral retractor for veterinary use in animal husbandry. Background Art

[0002] Animal husbandry is the use of livestock and poultry that have been domesticated by humans. Through artificial breeding and reproduction, it enables the conversion of plant energy such as forage and feed into animal energy. When raising livestock, it is necessary to open the oral cavity for treatment and examination. Existing animal husbandry oral retractors only open the mouth of the animal. During use, it is easy to drop the animal husbandry oral retractor. At this time, it is necessary to interrupt the medicine irrigation and gastric lavage operations and re-open the mouth of the animal, which is troublesome and inconvenient to operate. Existing patent documents have made improvements in this regard.

[0003] For example, in Chinese Patent CN216985286U, an animal husbandry oral retractor for veterinary use in animal husbandry includes an implement main body. The implement main body includes a holding rod and a movable arm. Elastic material limiting rings are fixed on the left and right sides of the holding rod. One side of the movable arm close to the holding rod is connected with a connecting block. A driving disk is connected between one side of the connecting block and the movable arms. The side of the movable arm far from the holding rod is connected with a retracting block. The outside of the retracting block is connected with a lateral plate. A number of groups of one-way holes are formed on the surface of the lateral plate. By setting the holding rod, movable arm, connecting block, driving disk, and retracting block, it is possible to conveniently retract the oral cavity of livestock, making it more labor-saving and convenient to use, and making the device more efficient when in use.

[0004] Although the device in the above document can conveniently open the mouth of livestock, reduce the resistance of rejection, and prevent it from falling off the hand, it still has obvious defects in actual use, such as:

[0005] Although the device can conveniently open the mouth of livestock, when the livestock opens its mouth, it will feel uncomfortable, so its head will swing forcefully. In this state, even if the staff has great strength, it is difficult to firmly hold the handle of the device by hand. And even if it can be held, it is a physical confrontation between humans and livestock, which is not only inefficient but also increases the risk. At the same time, when the device opens the mouth of livestock, it can only retract on both sides or in the middle. When retracting on one side of the two sides, it will only cause unbalanced retraction of the oral cavity on the other side. If in the middle, it is easy to block the oral cavity, making it inconvenient for the staff to use tools for treatment operations;

[0006] Therefore, there is a need to design an animal husbandry oral retractor for veterinary use in animal husbandry that can increase stability and facilitate quality control to solve such defects. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides a livestock oral retractor for veterinary use, which solves the problems of unstable use and inconvenient treatment of existing oral retractors.

[0011] Preferably, a rotating cross bar is rotatably connected between both sides of the inner cavity of the flipping notch through a bearing member, a supporting rotating frame is fixedly connected to the surface of the rotating cross bar, gears are fixedly connected to both sides of the surface of the rotating cross bar, a metal hose is fixedly connected to the surface of the supporting rotating frame through a fixing block, and a plurality of metal hoses are provided. A lighting lamp is fixedly connected to the bottom end of the middle metal hose, and snap rings are fixedly connected to the bottom ends of both side metal hoses through fixing blocks.

[0012] Preferably, the expansion and locking mechanism includes an upper horizontal plate and a lower horizontal plate. Guide sockets for matching use with the tooth plate rods and the concave sliding grooves are respectively arranged on both sides of the surfaces of the upper horizontal plate and the lower horizontal plate, and the upper horizontal plate and the lower horizontal plate are slidably installed on the surfaces of the tooth plate rods through the guide sockets.

[0013] Preferably, circular rotating grooves are respectively arranged on both sides of the tops of the upper horizontal plate and the lower horizontal plate. A threaded rod is rotatably connected between the inner sides of the two circular rotating grooves on the same side through a bearing member, and longitudinal tooth plates for matching use with the gears are fixedly connected to both sides of the rear part of the upper horizontal plate through fixing blocks.

[0014] Preferably, upper and lower parts of the surface of the threaded rod are both threadedly connected with threaded sleeves, and an expanding mouth bent plate is fixedly connected between the two threaded sleeves, and the two expanding mouth bent plates are used in cooperation with each other.

[0015] Preferably, a sliding collar is fixedly connected to the side of the threaded sleeve away from the flaring bent plate through a fixing plate. A lifting pressure rod is slidably installed inside the sliding collar. One end of the lifting pressure rod away from the sliding collar is fixedly connected with a concave tooth engaging with the tooth plate rod, and a spring is sleeved on the surface of the lifting pressure rod.

[0016] Preferably, bearing ring frames are fixedly connected to both sides of the bottom of the lower transverse plate through fixing blocks, and a worm gear is fixedly connected to the bottom end of the threaded rod through a fixing block.

[0017] Preferably, a driven rod is rotatably connected between the inner sides of the two bearing ring frames. Threaded grooves meshing with the worm gear are formed on both sides of the surface of the driven rod, and polygonal knobs are fixedly connected to both ends of the driven rod.

[0018] The present invention provides a livestock oral dilator for veterinary use. Compared with the existing technology, it has the following beneficial effects:

[0019] (1) For the livestock oral dilator for veterinary use, by using the blocking and positioning mechanism and the expansion and locking mechanism in a combined manner, the settings of these structures can utilize the linkage between the structures of the expansion and locking mechanism to fixedly connect the whole expansion and locking mechanism with the blocking and positioning mechanism, thereby clamping the neck of the livestock to prevent the head from stretching back and forth. At the same time, the two flaring bent plates open the mouth of the livestock, and can lock the upper transverse plate and the lower transverse plate on the surface of the tooth plate rod. After opening the mouth of the livestock, the head of the livestock can be limited by the flaring bent plates plus the upper and lower blocking plates to prevent the head of the livestock from swinging and affecting the operation, which is convenient for the staff to use.

[0020] (2) For the livestock oral dilator for veterinary use, by installing a worm gear meshing with the threaded groove at the bottom end of the threaded rod and using the concave tooth in cooperation, the settings of these structures can drive the two threaded rods to rotate synchronously by rotating the driven rod, so that the upper and lower flaring bent plates can press the four concave teeth and accurately engage with the tooth plate rod at the same time, thus quickly completing the locking between the expansion and locking mechanism and the blocking and positioning mechanism. When the flaring bent plates expand the mouth of the livestock, it can prevent the livestock from feeling uncomfortable and swinging its head, causing the equipment to shake and shift, improving the stability and smoothness during expansion. And the setting of the upper and lower flaring bent plates can effectively avoid blocking the oral cavity and facilitate oral operations.

[0021] (3) The livestock and veterinary oral retractor has a support rotating frame installed on the inner side of the flipping notch by a rotating cross bar, and several metal hoses are installed on one side of the support rotating frame. The setting of these structures can drive the support rotating frame to flip the lighting lamp and the snap ring buckle to the front when the expansion locking mechanism and the blocking and retracting positioning mechanism are installed. Moreover, the bendable metal hoses can adjust the lighting lamp and the snap ring buckle at multiple angles. The adjusted lighting lamp can illuminate the oral cavity, while the snap ring buckle can assist in fixing tools such as syringes, improving the overall practicality and functionality of the device.

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

[0032] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a livestock and veterinary oral dilator for livestock, including a retarding and positioning mechanism 1, and the retarding and positioning mechanism 1 includes a positioning base 101, and an expanding and locking mechanism 2 is installed on the upper part of the positioning base 101.

[0033] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5, which shows the overall structure of the anti-receding positioning mechanism 1. The top of the positioning base 101 is fixedly connected with a lower anti-receding plate 102 through a bracket. The top of the lower anti-receding plate 102 is provided with an upper anti-receding plate 103. The surfaces of the lower anti-receding plate 102 and the upper anti-receding plate 103 are both provided with annular bayonets 104 that are used in cooperation. On both sides of the top of the lower anti-receding plate 102, positioning sockets 105 penetrating through to the bottom are provided. On both sides of the bottom of the upper anti-receding plate 103, positioning rods 106 are fixedly connected through fixing blocks, and the bottom ends of the positioning rods 106 extend to the inside of the positioning sockets 105. On both sides of the surfaces of the lower anti-receding plate 102 and the upper anti-receding plate 103, toothed plate rods 107 are fixedly connected through fixing blocks. Concave sliding grooves 108 are provided on the opposite sides of the upper and lower toothed plate rods 107. A flipping notch 109 is provided on the upper part of the surface of the upper anti-receding plate 103. Between the two sides of the inner cavity of the flipping notch 109, a rotating cross bar 110 is rotatably connected through a bearing member. A supporting rotating frame 111 is fixedly connected to the surface of the rotating cross bar 110. Gears 112 are fixedly connected to both sides of the surface of the rotating cross bar 110. A metal hose 113 is fixedly connected to the surface of the supporting rotating frame 111. The metal hose 113 can be bent and positioned and adjusted in orientation, and a number of metal hoses 113 are provided. The bottom end of the middle metal hose 113 is fixedly connected with a lighting lamp 114. The bottom ends of the metal hoses 113 on both sides are fixedly connected with snap rings 115 through fixing blocks.

[0034] Before use, first fix the positioning base 101 to the ground using bolt assemblies, and at the same time position the lower anti-receding plate 102. Subsequently, install the upper anti-receding plate 103 on the top of the lower anti-receding plate 102, and insert the positioning rods 106 into the inside of the positioning sockets 105. When in use, first pull up the upper anti-receding plate 103 by the limit of the positioning rods 106, then pass the livestock through the annular bayonet 104 and lower the upper anti-receding plate 103. At this time, the neck of the livestock is caught by the annular bayonet 104. Then lift the entire expansion locking mechanism 2 so that the four guiding sockets 205 are aligned with the toothed plate rods 107 and installed. After the guiding sockets 205 are aligned with the toothed plate rods 107, push the entire expansion locking mechanism 2 to slide backward until the two closed expanding nozzle plates 208 are placed into the mouth of the livestock and stop moving. While the expansion locking mechanism 2 moves backward, the teeth on the tops of the two longitudinal toothed plates 206 will first engage with the gears 112 and drive the supporting rotating frame 111 to rotate 180 degrees, rotating the lighting lamp 114 and the snap rings 115 to the front.

[0035] Please refer to Figure 6 , Figure 7 and Figure 8, which shows the overall structure of the expansion locking mechanism 2. The expansion locking mechanism 2 includes an upper transverse plate 201 and a lower transverse plate 202. Guide sockets 205 that are used in cooperation with the tooth plate rod 107 and the concave chute 108 are provided on both sides of the surfaces of the upper transverse plate 201 and the lower transverse plate 202. The upper transverse plate 201 and the lower transverse plate 202 are both slidably mounted on the surface of the tooth plate rod 107 through the guide sockets 205. Circular rotating grooves 203 are provided on both sides of the tops of the upper transverse plate 201 and the lower transverse plate 202. A threaded rod 204 is rotatably connected between the inner sides of two circular rotating grooves 203 on the same side through a bearing member. The thread grooves on the upper and lower parts of the surface of the threaded rod 204 are arranged in opposite directions. Longitudinal tooth plates 206 that are used in cooperation with the gear 112 are fixedly connected to both sides of the rear part of the upper transverse plate 201 through fixing blocks. Threaded sleeves 207 are threadedly connected to both the upper and lower parts of the surface of the threaded rod 204. A nozzle expanding bent plate 208 is fixedly connected between the two threaded sleeves 207. A rubber layer is wrapped on the surface of the nozzle expanding bent plate 208 to protect the oral cavity. The two nozzle expanding bent plates 208 are used in cooperation with each other. A sliding collar 209 is fixedly connected to the side of the threaded sleeve 207 away from the nozzle expanding bent plate 208 through a fixing plate. A lifting pressure rod 210 is slidably mounted inside the sliding collar 209. A concave clamping tooth 211 that is used in cooperation with the tooth plate rod 107 is fixedly connected to the end of the lifting pressure rod 210 away from the sliding collar 209. A spring 212 is sleeved on the surface of the lifting pressure rod 210. Bearing ring frames 214 are fixedly connected to both sides of the bottom of the lower transverse plate 202 through fixing blocks. A worm gear 213 is fixedly connected to the bottom end of the threaded rod 204 through a fixing block. A driven rod 215 is rotatably connected between the inner sides of the two bearing ring frames 214. Threaded grooves 216 that are meshed with the worm gear 213 are provided on both sides of the surface of the driven rod 215. Polygonal knobs 217 are fixedly connected to both ends of the driven rod 215.

[0036] After the mouth-expanding curved plate 208 is placed inside the mouth of the livestock, rotate the two multi-angle knobs 217. Under the limit of the bearing ring frame 214, the driven rod 215 is driven to rotate. At this time, since the worm gear 213 and the worm thread groove 216 are in a meshing relationship, when the driven rod 215 rotates, it will drive the two threaded rods 204 to rotate synchronously. When the threaded rods 204 rotate, the threaded sleeves 207 will drive the upper and lower mouth-expanding curved plates 208 to move away from each other. At this time, the opened mouth-expanding curved plates 208 will expand and open the mouth of the livestock. When the mouth-expanding curved plate 208 moves up and down, it will push the concave-shaped teeth 211 on the upper and lower parts to first engage with the teeth of the tooth plate rod 107, and then the sliding collar 209 will continue to slide and compress the spring 212. After the mouth-expanding curved plate 208 opens the mouth of the livestock to an appropriate height, stop rotating the driven rod 215. At this time, through the engagement of the concave-shaped teeth 211 and the tooth plate rod 107, the expansion locking mechanism 2 is completely positioned with the tooth plate rod 107. At the same time, the docking of the guiding socket 205 and the tooth plate rod 107 also fixes the lower anti-receding plate 102 and the upper anti-receding plate 103. At this time, the equipment installation is completed. Then, pull the metal hose 113 to make the lighting lamp 114 illuminate the mouth of the livestock, and use tools to conduct quality inspection on the livestock. The syringe can be stuck inside the snap ring buckle 115 for auxiliary injection. After the inspection is completed, rotate the driven rod 215 in the reverse direction to drive the two mouth-expanding curved plates 208 to close towards each other to close the mouth of the livestock. At the same time, the spring 212 pushes the concave-shaped teeth 211 to separate from the tooth plate rod 107. At this time, the guiding socket 205 loses its lock, and pull the expansion locking mechanism 2 to withdraw from the surface of the tooth plate rod 107. Then, push up the upper anti-receding plate 103 to separate it from the lower anti-receding plate 102, and then pull the livestock out from the inside of the annular bayonet 104.
