Description

Technical Field

[0001] This utility model relates to the field of thawing frozen semen, specifically a thawing device for frozen bovine semen. Background Technology

[0002] Frozen bovine semen refers to a semen product that can be stored for a long time, obtained through a series of professional processes such as dilution, balancing, and freezing of the semen of healthy and superior breeding cattle. It can overcome the limitations of time and space, allowing the genetic material of superior breeding cattle to be widely disseminated and utilized, and is indispensable in bovine artificial insemination technology.

[0003] In actual operation on existing ranches, thawing cups are widely used thawing equipment when thawing semen tubes from frozen bovine semen. These thawing cups are equipped with a constant temperature heating system and a timing system. The water temperature inside is generally precisely set at around 38°C. After the staff takes the semen tube out of the liquid nitrogen tank, they place it into the thawing cup and then press the timing button. When the 30-second thawing time is over, the staff will use a special lifter with a disc with filter holes at the bottom and a column fixed at the top. The staff can lift the semen tube from the water in the thawing cup by holding the column.

[0004] However, the existing lifting device has certain inconveniences. Because the lifting device's rod is made of metal, and in order to make it easier for workers to grab the top of the rod, the top of the metal rod is usually level with or even higher than the rim of the thawing cup. This means that when workers need to put the lid on top of the thawing cup, they must first remove the lifting device from the thawing cup; otherwise, the lid cannot be closed smoothly. Consequently, this type of lifting device is difficult to carry conveniently with the thawing cup, causing trouble for the operation and movement of ranch workers. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a thawing device for frozen bovine semen to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thawing device for frozen bovine semen, comprising a lifting rod, a connecting rod, and a thawing cup. A lifting ball is fixed to the top of the lifting rod, a floating plate is provided on the outer wall of the lifting rod, and two sets of cavities are opened inside the lifting rod. A connecting rod is connected to the bottom of one set of cavities. A limit block is provided at the top of the connecting rod, and a support plate and a support plate are installed at the bottom of the connecting rod. The lifting rod, the connecting rod, and the support plate are combined to form a lifting assembly. A constant temperature chamber is provided inside the thawing cup, and a cup lid is installed on the top of the thawing cup.

[0007] By adopting the above technical solution, the technical problem of existing lifters being difficult to store in the thawing cup is solved. When personnel need to seal the thawing cup containing warm water, they can rotate the lid onto the top of the thawing cup. During the process of placing the lid on the top of the thawing cup, the protrusion inside the lid will press down on the lifting ball, causing the lifting ball to push the lifting rod into the thawing cup. The top of the connecting rod retracts back into a set of cavities inside the lifting rod, thus allowing the lifting component to be stored inside the thawing cup, making it convenient for personnel to carry both.

[0008] The present invention is further configured such that the lifting ball is hollow inside, and the lifting rod, the lifting ball and the floating plate are all made of polypropylene plate, and the polypropylene plate has a honeycomb structure inside.

[0009] Preferably, when the constant temperature chamber inside the defrosting cup is filled with enough water, the floating plate will float on the water surface.

[0010] The present invention is further configured such that the distance between the lifting ball and the floating plate is greater than the distance between the top wall of the constant temperature chamber and the top port of the thawing cup.

[0011] Preferably, during the thawing process of the semen tube inside the thawing cup, the lifting ball is positioned above the port of the thawing cup, making it convenient for personnel to grasp the lifting ball.

[0012] The present invention is further configured such that a protrusion is fixed inside the cup lid, and the length of the protrusion is less than the length of the connection point at the port of the defrosting cup.

[0013] Preferably, the protrusion inside the lid can be used to position the lid when it is closed to the defrosting cup, ensuring that the lid is tightened accurately.

[0014] The present invention is further configured such that a sealing gasket is fitted on the outer wall of the protrusion, and the sealing gasket is fixedly installed on the inner wall of the cup lid.

[0015] Preferably, when the lid is installed on the top of the thawing cup, the top port of the thawing cup presses against the sealing gasket inside the lid, and the sealing gasket can seal the gap between the port of the thawing cup and the lid.

[0016] The present invention is further configured such that a through hole is provided at the top of the set of cavities, and the diameter of the through hole is smaller than the radius of the cavity.

[0017] Preferably, when the connecting rod retracts into the cavity inside the lifting rod, the water inside the cavity will flow out of the cavity through the through hole, thereby reducing the resistance when the connecting rod retracts into the lifting rod.

[0018] The present invention is further configured such that the support plate has multiple sets of guide holes inside, the guide holes are tapered, and the top diameter of the guide holes is larger than the bottom diameter of the guide holes.

[0019] Preferably, when a person places the semen tube into the thawing cup, the semen tube will slide down the inclined inner wall of the guide hole until the bottom of the semen tube contacts the support plate.

[0020] The present invention is further configured such that the support plate has multiple sets of water flow holes inside, the water flow holes are offset from the guide holes, and the diameter of the water flow holes is smaller than the diameter of the semen tube.

[0021] Preferably, the support plate supports the semen tube, so that the rising support plate can carry the semen tube up with it.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the technical problem of existing lifters being difficult to store in a thawing cup by setting up a lifting rod, lifting ball, floating plate, connecting rod, limiting block, and cavity. When personnel need to seal a thawing cup containing warm water, they can rotate the lid onto the top of the thawing cup. During the process of placing the lid on the top of the thawing cup, the protrusion inside the lid will press down on the lifting ball, causing the lifting ball to push the lifting rod into the thawing cup. The top of the connecting rod retracts into a set of cavities inside the lifting rod, thus allowing the lifting component to be stored inside the thawing cup, making it convenient for personnel to carry both.

[0024] 2. This utility model, by setting up a support plate, guide hole, support plate and water flow hole, allows the semen tube to slide down along the inclined inner wall of the guide hole when the personnel put the semen tube into the thawing cup. Because the guide hole on the support plate is set as a cone and the diameter of the top of the guide hole is larger than the diameter of its bottom, the semen tube will contact the support plate at the bottom. The support plate supports the semen tube, and the support plate supports the semen tube, so that the semen tube is in an upright state, which makes it convenient for personnel to take out the semen tube during the lifting process of the lifting component.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Please see Figure 1 — Figure 6 The assembly includes a lifting rod 1, a connecting rod 2, and a defrosting cup 3. A lifting ball 101 is fixed to the top of the lifting rod 1, and a floating plate 102 is provided on the outer wall of the lifting rod 1. Two sets of cavities 103 are formed inside the lifting rod 1. The bottom of one set of cavities 103 is connected to the connecting rod 2. A limit block 201 is provided at the top of the connecting rod 2, and a support plate 202 and a support plate 204 are installed at the bottom of the connecting rod 2. The lifting rod 1, connecting rod 2, and support plate 204 are combined to form a lifting assembly. A constant temperature chamber 301 is provided inside the defrosting cup 3, and a cup lid 302 is installed on the top of the defrosting cup 3. This solves the problem of existing... There is a technical problem that the lifting device is difficult to store in the defrosting cup. When personnel need to seal the defrosting cup 3 containing warm water, they can rotate the cup lid 302 to install on the top of the defrosting cup 3. During the process of placing the cup lid 302 on the top of the defrosting cup 3, the protrusion 303 inside the cup lid 302 will press down on the lifting ball 101, so that the lifting ball 101 will press the lifting rod 1 into the defrosting cup 3. The top of the connecting rod 2 will retract back into a set of cavities 103 inside the lifting rod 1, so that the lifting component can be stored inside the defrosting cup 3, making it convenient for personnel to carry both.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 6The lifting ball 101 is hollow inside. The lifting rod 1, the lifting ball 101 and the floating plate 102 are all made of polypropylene board, and the polypropylene board has a honeycomb structure inside. When enough water is injected into the constant temperature chamber 301 inside the thawing cup 3, the floating plate 102 will float on the water surface.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The distance between the lifting ball 101 and the floating plate 102 is greater than the distance between the top wall of the constant temperature chamber 301 and the top port of the thawing cup 3. During the thawing process of the semen tube inside the thawing cup 3, the lifting ball 101 is located above the port of the thawing cup 3, which makes it convenient for personnel to grab the lifting ball 101.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The inside of the cup lid 302 is fixed with a protrusion 303, and the length of the protrusion 303 is less than the length of the connection at the port of the defrosting cup 3. The protrusion 303 inside the cup lid 302 can play a positioning role when the cup lid 302 is closed with the defrosting cup 3, ensuring that the cup lid 302 is tightened accurately.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The outer wall of the protrusion 303 is fitted with a sealing gasket 304, and the sealing gasket 304 is fixedly installed on the inner wall of the cup lid 302. When the cup lid 302 is installed on the top of the thawing cup 3, the top port of the thawing cup 3 squeezes the sealing gasket 304 inside the cup lid 302, and the sealing gasket 304 can seal the gap between the port of the thawing cup 3 and the cup lid 302.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 A through hole 104 is provided at the top of a set of cavities 103, and the diameter of the through hole 104 is smaller than the radius of the cavity 103. When the connecting rod 2 retracts into the cavity 104 inside the lifting rod 1, the water inside the cavity 104 will flow out of the cavity 104 through the through hole 104, thereby reducing the resistance when the connecting rod 2 retracts into the lifting rod 1.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The support plate 202 has multiple sets of guide holes 203 inside, and the guide holes 203 are set in a conical shape. The top diameter of the guide hole 203 is larger than the bottom diameter of the guide hole 203. When the personnel put the semen tube into the thawing cup 3, the semen tube will slide down along the inclined inner wall of the guide hole 203 until the bottom of the semen tube contacts the support plate 204.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 1The support plate 204 has multiple sets of water flow holes 205 inside. The water flow holes 205 are offset from the guide holes 203. The diameter of the water flow holes 205 is smaller than the diameter of the semen tube. The support plate 204 supports the semen tube, so that the rising support plate 204 can carry the semen tube up together.

[0043] In practical operation: The operator opens the lid 302 and fills the constant-temperature chamber 301 inside the thawing cup 3 with sufficient water. The operator can adjust the constant-temperature heating system and timing system inside the thawing cup 3 using the temperature and timer buttons on the outer wall of the thawing cup 3. The constant-temperature heating system inside the thawing cup 3 heats the water inside the constant-temperature chamber 301 until the water temperature stabilizes at 38°C. Before placing the frozen semen tube into the constant-temperature chamber 301, the lifting rod 1 inside the thawing cup 3, due to its internal structure with two sets of cavities 103 and a floating plate 102, allows the lifting assembly to unfold. At this time, the floating plate 102 floats on the water surface, and the height of the lifting ball 101 at the top of the lifting rod 1 is higher than the top port of the thawing cup 3. Subsequently, the operator places the semen tube into the thawing cup 3. In the process, because the guide hole 203 on the support plate 202 is set as a cone and the diameter of the top of the guide hole 203 is larger than the diameter of its bottom, the semen tube will slide down along the inclined inner wall of the guide hole 203 until the bottom of the semen tube contacts the support plate 204. The support plate 204 supports the semen tube. When the semen tube is put into the thawing cup 3, the personnel immediately press the timing button on the outer wall of the thawing cup 3. When the timing ends, the personnel lift the lifting component upward through the lifting ball 101. The lifting rod 1 drives the connecting rod 2 to move upward through the limiting block 201 at the top of the connecting rod 2. During the process of the lifting component rising, the support plate 204 lifts the semen tube upward, and the support plate 202 supports the semen tube through the guide hole 203. When the semen tube is exposed from the thawing cup 3, the personnel take out the thawed semen tube.

[0044] When a person needs to place the lid 302 on the defrosting cup 3, the protrusion 303 inside the lid 302 will press down on the lifting ball 101, causing the lifting ball 101 to press the lifting rod 1 into the defrosting cup 3. The top of the connecting rod 2 retracts back into a set of cavities 103 inside the lifting rod 1, so that the inside of the lid 302 covers the top of the defrosting cup 3.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
