Description

Technical Field

[0001] This utility model belongs to the field of bovine embryo cryopreservation technology, specifically relating to a bovine embryo cryopreservation device. Background Technology

[0002] A bovine embryo cryopreservation device is a specialized instrument for the cryopreservation of bovine embryos. This device uses specific freezing technology to ensure the bovine embryos remain viable at low temperatures, guaranteeing their safety and survival rate during the freezing process, so that they can be subsequently used for embryo transfer or other related research.

[0003] A utility model patent with patent authorization announcement number CN219762336U discloses a cryopreservation device for beef cattle breeding embryos, including a container and a cover on top of the container. A cylindrical frame is provided at the bottom inside the container, and beef cattle breeding embryos are placed in the cylindrical frame. Liquid nitrogen is filled at the bottom inside the container.

[0004] However, existing bovine embryo cryopreservation devices also have certain shortcomings. Most existing bovine embryo cryopreservation devices use manual operation to extract and retrieve embryos from the tanks. Due to factors such as the inner diameter and depth of the liquid nitrogen tank, they are very inconvenient for people to use. Summary of the Invention

[0005] The purpose of this invention is to provide a bovine embryo cold storage device, which solves the problem that existing bovine embryo cold storage devices mostly use manual operation to extract and retrieve embryos from the tank, and are inconvenient to use due to factors such as the inner diameter and depth of the liquid nitrogen tank.

[0006] To achieve the above objectives, this utility model provides a bovine embryo cryopreservation device, comprising a liquid nitrogen tank, a tank lid contacting the upper end of the liquid nitrogen tank, a sealing ring fixedly sleeved on the outer side of the end of the tank lid, the sealing ring being slidably connected to the liquid nitrogen tank, two symmetrically distributed connecting rods fixedly connected to the end of the tank lid, a fixing frame fixedly connected to the lower ends of the two connecting rods, an embryo tank fixedly connected to the bottom inner side of the fixing frame, a support frame fixedly connected to the outer side of the liquid nitrogen tank, a toothed plate slidably connected to the opening groove of the support frame, the toothed plate being fixedly connected to the tank lid, a motor mounted on the horizontal part of the support frame via a support member, a gear fixedly sleeved on the outer side of the output shaft of the motor, the gear meshing with the toothed plate, a positioning mechanism being provided on both the tank lid and the support frame, and an oil injection mechanism being provided on the horizontal part of the support frame.

[0007] The principle of this utility model is as follows: the starting motor drives the output shaft to rotate, which in turn drives the gear to rotate. Under the meshing relationship, the gear drives the tooth plate to move upward, which in turn drives the can cover to move, and then drives the connecting rod to move. When the connecting rod moves, it can drive the fixed frame to move, and finally drive the embryo tank to move upward, so that the embryo tank is exposed from the liquid nitrogen tank, making it convenient for the user to take out the material.

[0008] When the lid moves, the guide block slides along the vertical part of the support frame to guide the lid's movement and ensure its stability. The lid's movement also moves the locking rod. Under the pressure of the inner wall of the locking hole, the locking rod moves to the right, allowing the telescopic frame to move stably along the inner wall of the fixed plate. Once the spring deforms, the locking rod disengages from the locking hole. Under the force, the locking rod slides along the inner wall of the support frame. When the locking rod slides into the next locking hole, the spring returns to its original shape, pulling the locking rod back into the locking hole to position the lid and thus precisely control the embryo tank.

[0009] By pushing the oil injection pipe to deflect it, the vertical part on the left side of the oil injection pipe is positioned above the opening slot of the horizontal part of the support frame. Then, the push plate is pushed upward to move the end rod along the inner wall of the horizontal part of the support frame and to move the sealing push plate along the inner wall of the oil reservoir, thus pushing the lubricating oil. This allows the lubricating oil to flow out through the oil injection pipe and finally come into contact with the gear plate and gears, providing lubrication between them to reduce hard wear and ensure good transmission performance.

[0010] The beneficial effects of this utility model are as follows: This solution, through the setting of structures such as motors, gears, and toothed plates, can drive the can lid to move, thereby driving the fixed frame to move, and then driving the embryo tank to move, enabling automatic material handling of the embryo tank. Under the action of structures such as locking holes, locking rods, and springs, the movement of the can lid can be limited, thereby accurately positioning the embryo tank. By pushing the oil injection pipe to deflect, the left vertical part of the oil injection pipe is positioned above the opening groove of the support frame. Under the action of structures such as end rods and sealing push plates, the lubricating oil can be pushed to flow, and with the guiding effect of the oil injection pipe, the lubricating oil comes into contact with the gears and toothed plates, thereby reducing hard wear between the toothed plates and gears.

[0011] Furthermore, the positioning mechanism includes a guide block, which is fixedly connected to the upper end of the can lid. The guide block is slidably connected to the vertical part of the support frame. The vertical part of the support frame has a locking hole. A fixing plate is fixedly connected to the upper left side of the can lid. A telescopic frame is slidably connected to the inner wall of the fixing plate. A locking rod is fixedly connected to the left end of the telescopic frame. The locking rod is slidably connected to the locking hole. An end plate is fixedly connected to the right end of the telescopic frame. A spring is provided on the outer side of the telescopic frame. Through the combined use of the locking hole, locking rod, and other structures, the can lid can be moved and limited, thereby positioning the embryo can.

[0012] Furthermore, there are two locking holes, which are evenly distributed on the left vertical part of the support frame. The locking holes facilitate the use of locking rods for engagement.

[0013] Furthermore, one end of the spring is welded to the end plate, and the other end of the spring is welded to the telescopic frame. The end plate can be connected and used through the setting of the spring.

[0014] Furthermore, the oil injection mechanism includes an oil reservoir. The oil reservoir is fixedly connected to the horizontal part of the support frame. An end rod is slidably connected to the horizontal part of the support frame. The end rod is slidably connected to the oil reservoir. A push plate is fixedly connected to the lower end of the end rod. A spring is provided on the outer side of the end rod. A sealing push plate is fixedly connected to the upper end of the end rod. The sealing push plate is slidably connected to the oil reservoir. By pushing the push plate upward, the end rod is moved, which in turn causes the sealing push plate to slide along the inner wall of the oil reservoir, pushing the lubricating oil to facilitate subsequent lubrication of gears and other components.

[0015] Furthermore, an oil injection pipe is installed inside the oil reservoir via a bearing. The vertical part of the oil injection pipe on the left side is located above the opening groove of the support frame. The oil injection pipe allows for the diversion and use of lubricating oil.

[0016] Furthermore, one end of the second spring is welded to the push plate, and the other end of the second spring is welded to the horizontal part of the support frame. The push plate can be connected and used through the setting of the second spring. Attached Figure Description

Detailed Implementation

[0024] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment provides a bovine embryo cryopreservation device, including a liquid nitrogen tank 1. The upper end of the liquid nitrogen tank 1 is in contact with a tank lid 2. A sealing ring 3 is fixedly sleeved on the outer side of the end of the tank lid 2. The sealing ring 3 is slidably connected to the liquid nitrogen tank 1. Two symmetrically distributed connecting rods 4 are fixedly connected to the end of the tank lid 2. The lower ends of the two connecting rods 4 are jointly fixedly connected to a fixing frame 5. An embryo tank 6 is fixedly connected to the bottom inner side of the fixing frame 5. A support frame 7 is fixedly connected to the outer side of the liquid nitrogen tank 1. A toothed plate 8 is slidably connected to the opening groove of the support frame 7. The toothed plate 8 is fixedly connected to the tank lid 2. A motor 9 is installed on the horizontal part of the support frame 7 through a support member. A gear 90 is fixedly sleeved on the outer side of the output shaft of the motor 9. The gear 90 meshes with the toothed plate 8.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a positioning mechanism 10 is provided on both the lid 2 and the support frame 7. The positioning mechanism 10 includes a guide block 101. The upper end of the lid 2 is fixedly connected to the guide block 101, which is slidably connected to the vertical part of the support frame 7. The vertical part of the support frame 7 has a locking hole 102. The upper left side of the lid 2 is fixedly connected to a fixing plate 103. The inner wall of the fixing plate 103 is slidably connected to a telescopic frame 104. The left end of the telescopic frame 104 is fixedly connected to a locking rod 105, which is slidably connected to the locking hole 102. The right end of the telescopic frame 104 is fixedly connected to an end plate 106. A spring 107 is provided on the outer side of the telescopic frame 104. Through the cooperation of the locking hole 102, locking rod 105 and other structures, the lid 2 can be moved and limited, thereby positioning the embryo tank 6.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, there are two locking holes 102. The two locking holes 102 are evenly distributed on the left vertical part of the support frame 7. The locking holes 102 facilitate the locking with the locking rod 105. One end of the spring 107 is welded to the end plate 106, and the other end of the spring 107 is welded to the telescopic frame 104. The spring 107 can be used to connect the end plate 106.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the horizontal part of the support frame 7 is provided with an oil injection mechanism 11. The oil injection mechanism 11 includes an oil reservoir 111. The oil reservoir 111 is fixedly connected to the horizontal part of the support frame 7. An end rod 113 is slidably connected to the horizontal part of the support frame 7. The end rod 113 is slidably connected to the oil reservoir 111. A push plate 114 is fixedly connected to the lower end of the end rod 113. A spring 115 is provided on the outer side of the end rod 113. A sealing push plate 116 is fixedly connected to the upper end of the end rod 113. The sealing push plate 116 is slidably connected to the oil reservoir 111. By pushing the push plate 114 upward, the end rod 113 is moved, which in turn causes the sealing push plate 116 to slide along the inner wall of the oil reservoir 111, pushing the lubricating oil to facilitate subsequent lubrication of gears 90 and the like.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, an oil injection pipe 112 is installed inside the oil reservoir 111 via a bearing. The vertical part of the oil injection pipe 112 is located on the upper side of the opening slot of the support frame 7. The oil injection pipe 112 can be used to guide the flow of lubricating oil. One end of the second spring 115 is welded to the push plate 114, and the other end of the second spring 115 is welded to the horizontal part of the support frame 7. The push plate 114 can be connected to the second spring 115.

[0029] The specific implementation process of this utility model is as follows: The motor 9 is started to drive the output shaft to rotate, thereby driving the gear 90 to rotate. Under the meshing relationship, the gear 90 drives the tooth plate 8 to move upward, thereby driving the can cover 2 to move, and then driving the connecting rod 4 to move. When the connecting rod 4 moves, it can drive the fixed frame 5 to move, and finally drive the embryo tank 6 to move upward, so that the embryo tank 6 is exposed from the liquid nitrogen tank 1, making it convenient for the user to take out the material.

[0030] When the lid 2 moves, the guide block 101 can slide along the vertical part of the support frame 7 to guide the lid 2 and ensure the stability of the lid 2. When the lid 2 moves, the locking rod 105 can move. Under the pressure of the inner wall of the locking hole 102, the locking rod 105 can be pushed to the right to drive the telescopic frame 104 to move stably along the inner wall of the fixed plate 103. The spring 107 deforms and finally causes the locking rod 105 to disengage from the locking hole 102. Under the action of force, the locking rod 105 slides along the inner wall of the support frame 7. When the locking rod 105 slides into the next locking hole 102, the spring 107 returns to its original deformation to pull the locking rod 105 into the locking hole 102 to position the lid 2 and thus accurately control the embryo tank 6.

[0031] By pushing the oil injection pipe 112 to deflect it, the vertical part on the left side of the oil injection pipe 112 is positioned above the opening slot of the horizontal part of the support frame 7. Then, the push plate 114 is pushed upward to drive the end rod 113 to slide along the inner wall of the horizontal part of the support frame 7, and drive the sealing push plate 116 to slide along the inner wall of the oil reservoir 111 to push the lubricating oil. The lubricating oil flows out through the oil injection pipe 112, and finally the lubricating oil comes into contact with the gear plate 8 and the gear 90 to lubricate the gear plate 8 and the gear 90, so as to reduce the hard wear between the gear plate 8 and the gear 90 and ensure good transmission effect.

[0032] This solution, through the configuration of motor 9, gear 90, toothed plate 8, etc., can drive the tank cover 2 to move, thereby moving the fixed frame 5, and then moving the embryo tank 6, enabling automatic material handling of the embryo tank 6. Under the action of the clamping hole 102, clamping rod 105, spring 107, etc., the movement of the tank cover 2 can be limited, thereby accurately positioning the embryo tank 6. By pushing the oil injection pipe 112 to deflect, the left vertical part of the oil injection pipe 112 is positioned above the opening groove of the support frame 7. Under the action of the end rod 113, sealing push plate 116, etc., the lubricating oil can be pushed to flow. With the guiding effect of the oil injection pipe 112, the lubricating oil comes into contact with the gear 90 and toothed plate 8, thereby reducing hard wear between the toothed plate 8 and gear 90.
