Description

Technical Field

[0001] The invention relates to the technical field of liquid nitrogen tank storage, and in particular to a storage device for a liquid nitrogen tank for reproductive medicine embryos. Background Art

[0002] In the clinical treatment of infertility in assisted reproductive medicine, the embryos of test tube baby patients need to be frozen and preserved. Currently, liquid nitrogen containers, also known as liquid nitrogen freezing tanks, are used. Due to the particularity of the tank body, reproductive medicine embryo liquid nitrogen tanks cannot be stacked vertically. Therefore, such reproductive medicine embryo liquid nitrogen tanks are usually placed directly in the storage room. This placement method not only wastes space, but is also extremely inconvenient to find.

[0003] To solve the above problems, a Chinese patent with publication number CN219920095U discloses a reproductive medicine embryo liquid nitrogen tank storage device, including a liquid nitrogen tank, a motor is fixedly connected to the inner bottom end of the liquid nitrogen tank, a roller is fixedly connected to the output end of the motor, gears are evenly arranged on the outer side of the roller, the outer side of the gears are meshed and connected with internal gears, the internal gears are connected through fixed rods, the tops of the fixed rods are rotatably connected to the inner top of the top cover, the tops of the internal gears are evenly arranged with empty slots, and the inside of the empty slots is slidably connected with brackets. The patent drives the motor, so that the gears on the outer side of the roller drive the internal gears to rotate, and the bracket where the numbered reproductive medicine embryo storage device is located is rotated to the right side of the liquid nitrogen tank, which is convenient for the staff to access, so that the reproductive medicine embryo liquid nitrogen tanks can be centrally stored and conveniently found directly.

[0004] The following problems existed during the actual use of the above patent: after placing the reproductive medicine embryo liquid nitrogen tank on the bottom plate, the staff needed to rotate the screws on the left and right sides of the bottom plate, adjust the distance between the two screws, and then adjust the distance between the two rubber pads, and use the two rubber pads to clamp and position the reproductive medicine embryo liquid nitrogen tank; and, the positioning of each reproductive medicine embryo liquid nitrogen tank required this operation, which was cumbersome and inefficient. Summary of the invention

[0005] The present invention is intended to provide a storage device for a reproductive medical embryo liquid nitrogen tank, so as to solve the problem that the storage method of the reproductive medical embryo liquid nitrogen tank by the existing storage device is complicated to operate.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a storage device for a liquid nitrogen tank for embryos in reproductive medicine, comprising a cylinder and a rotating shaft, a motor is arranged in the cylinder, and the output shaft of the motor is coaxially connected to the rotating shaft; a plurality of placement mechanisms are equidistantly arranged on the circular shaft in the circumferential direction, the placement mechanism comprises a fixed plate and a lifting block, the fixed plate is fixedly connected to the circular shaft, a plurality of placement parts are equidistantly arranged vertically on the fixed plate, the placement parts comprise a side plate fixedly connected to the fixed plate, an inclined groove provided on the fixed plate and located on both sides of the lifting block, and the lifting block is vertically slidably connected to a plurality of side plates at the same time; the spacing between the two inclined grooves gradually decreases from top to bottom, an auxiliary block is slidably connected in the inclined groove, and a clamping arm is arranged on the auxiliary block; an opening and an arc groove are arranged on the side wall of the cylinder, and a sealing plate for sealing the opening is slidably connected in the arc groove; and an adjustment mechanism is also included for adjusting the spacing between the two clamping arms on each side plate as the lifting block moves vertically.

[0007] The principles and advantages of this solution are:

[0008] 1. In this scheme, multiple reproductive medicine embryo liquid nitrogen tanks are placed on multiple side plates on a fixed plate respectively, and the lifting block is manually pressed downward to move. The two clamping arms on each side plate can be brought close to each other through the adjustment mechanism, so that the two clamping arms clamp and position the reproductive medicine embryo liquid nitrogen tank; compared with the prior art, this scheme can clamp and position multiple reproductive medicine embryo liquid nitrogen tanks on the fixed plate at the same time, which is easy to operate and effectively improves work efficiency.

[0009] 2. This solution can drive multiple fixed plates to rotate through the rotating shaft, so as to change the positions of different fixed plates, and then multiple reproductive medicine embryo liquid nitrogen tanks can be stored on multiple side plates on different fixed plates, thereby increasing the storage capacity and being highly practical.

[0010] 3. This solution can drive different fixed plates to change positions through the rotating shaft, so that the staff can store multiple reproductive medicine embryo liquid nitrogen tanks on multiple side plates on different fixed plates at the opening, which is easy to operate and effectively improves work efficiency.

[0011] Furthermore, the adjustment mechanism includes a plurality of adjustment units vertically equidistantly arranged on the lifting block, a guide block fixed to the fixed plate and a stopping unit for stopping the lifting block, the adjustment unit includes a transverse groove opened on both sides of the lifting block, a transverse block is slidably connected in the transverse groove, and the transverse block is fixed to the auxiliary block; the lifting block is vertically slidably connected to the guide block, and a spring is provided between the lifting block and the guide block.

[0012] Through the above arrangement, the vertical block moves downward and is stopped by the stopping unit.

[0013] During the downward movement of the lifting block, the lifting block drives the transverse block to move downward, and the transverse block drives the clamping arm to move obliquely downward along the path of the inclined groove through the auxiliary block, so that the two transverse blocks are close to each other, and the two clamping arms are also close to each other, that is, both clamping arms are close to the reproductive medicine embryo liquid nitrogen tank; the lifting block continues to move downward, and when the lifting block is positioned, the two clamping arms clamp and position the reproductive medicine embryo liquid nitrogen tank.

[0014] Furthermore, the stopping unit includes a rack fixed to the side wall of the lifting block, a circular shaft fixed to the fixed plate, and a stopping groove opened on the side wall of the lifting block. A torsion spring is provided between the circular shaft and the fixed plate. A gear is coaxially connected to the circular shaft, and the gear is located on the movement trajectory of the rack. A stop block for sliding into the stopping groove is provided on the circular shaft.

[0015] Through the above arrangement, during the downward movement of the lifting block, the lifting block drives the rack to move downward, so that the rack meshes with the gear and drives the gear to rotate clockwise, and the gear drives the round shaft to rotate clockwise, and the torsion spring deforms; during the clockwise rotation of the round shaft, the round shaft drives the stop block to rotate clockwise, so that the free end of the stop block is away from the lower end of the lifting block; the lifting block continues to move downward, so that the rack and the gear are separated, so that the round shaft rotates counterclockwise under the action of the torsion spring, and the round shaft drives the stop block to rotate counterclockwise, so that the free end of the stop block slides into the stop groove, thereby realizing the positioning of the lifting block; when the lifting block needs to move upward, the round shaft is manually rotated clockwise to move the free end of the stop block out of the stop groove, and then the lifting block moves upward under the action of the spring.

[0016] Furthermore, a handle is provided on the circular shaft.

[0017] Through the above arrangement, the round shaft is driven to rotate by the handle, which makes the operation easier.

[0018] Furthermore, a plurality of clamping mechanisms are vertically equidistantly arranged on the fixed plate, and the clamping mechanisms include a clamping block and a power unit for driving the clamping block to abut against the top of the reproductive medicine embryo liquid nitrogen tank.

[0019] Through the above arrangement, the power unit drives the pressing block to abut against the top of the reproductive medical embryo liquid nitrogen tank, thereby achieving compression of the reproductive medical embryo liquid nitrogen tank, thereby enhancing the positioning effect of the reproductive medical embryo liquid nitrogen tank.

[0020] Furthermore, the pressing block is elastic and arc-shaped, and the protrusion of the pressing block is set toward the bottom direction of the cylinder; the power unit includes a slide groove laterally opened on both sides of the side wall of the fixed plate, and a movable block fixed to the clamping arm, a movable rod is slidably connected in the slide groove, and a top groove is provided on the top of the movable block, and the movable rod is vertically slidably connected to the top groove; the two ends of the pressing block are respectively fixed to the two movable blocks.

[0021] Through the above arrangement, during the period when the clamping arm moves obliquely downward along the path of the inclined groove, the clamping arm drives the movable block to move synchronously, so that the movable rod and the movable block move laterally, that is, the two movable blocks approach each other, and at the same time, the movable block moves downward relative to the movable rod; during the period when the two movable blocks approach each other, the two ends of the pressing block also approach each other, thereby making the pressing block bulge downward more greatly; at the same time, during the period when the movable block moves downward relative to the movable rod, the movable block drives the pressing block to move downward at the same time, so that the bulge of the pressing block is against the top of the reproductive medical embryo liquid nitrogen tank, thereby achieving the compression of the reproductive medical embryo liquid nitrogen tank.

[0022] Furthermore, an elastic layer is provided at the bottom of the pressing block.

[0023] Through the above arrangement, the elastic layer replaces the pressing block to abut against the top of the reproductive medical embryo liquid nitrogen tank, thereby avoiding damage to the reproductive medical embryo liquid nitrogen tank; and the pressing block drives the elastic layer to abut against the top of the reproductive medical embryo liquid nitrogen tank to deform the elastic layer, which can increase the contact area between the elastic layer and the top of the reproductive medical embryo liquid nitrogen tank, thereby enhancing the positioning effect of the reproductive medical embryo liquid nitrogen tank.

[0024] Furthermore, a convex block is provided on the sealing plate.

[0025] Through the above arrangement, the sealing plate is driven to move along the path of the arc groove by the projection, which makes the operation more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A number of placement mechanisms are circumferentially equidistantly arranged on the circular shaft 35, and the placement mechanisms include a fixed plate 20 and a lifting block 21. The fixed plate 20 is fixedly connected to the circular shaft 35, and a number of placement parts are vertically equidistantly fixedly connected to the fixed plate 20. The placement parts include a side plate 22 fixedly connected to the fixed plate 20, and inclined grooves 23 opened on the fixed plate 20 and located on both sides of the lifting block 21.

When the rack 34 and the lifting block 21 move downward, the rack 34 first engages with the gear 37 to drive the circular shaft 35 to rotate clockwise, and the circular shaft 35 drives the stop block 38 to rotate clockwise, providing space for the lifting block 21 to move downward, so that the lifting block 21 will not be hindered by the stop block 38 from moving downward.

[0037] A plurality of clamping mechanisms are vertically equidistantly arranged on the fixed plate 20, and the clamping mechanism includes a clamping block 40 and a power unit for driving the clamping block 40 to abut against the top of the reproductive medical embryo liquid nitrogen tank 60. The clamping block 40 is elastic and arc-shaped. The protruding direction of the clamping block 40 is arranged toward the bottom direction of the cylinder 10, that is, the protruding direction of the clamping block 40 is arranged downward; the power unit includes a slide groove 41 transversely opened on both sides of the side wall of the fixed plate 20, and a movable block 42 fixedly connected to the clamping arm 24, a movable rod 43 is slidably connected in the slide groove 41, a top groove is opened on the top of the movable block 42, and the movable rod 43 is vertically slidably connected to the top groove; the two ends of the clamping block 40 are respectively fixedly connected to the two movable blocks 42.

[0038] The specific implementation process is as follows:

[0039] When in use, the sealing plate 15 is manually driven to slide along the path of the arc groove 14, so that the opening 13 is communicated with the outside.

[0040] Start the motor 12, the output shaft of the motor 12 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the multiple fixed plates 20 to rotate. When a single fixed plate 20 is facing the opening 13, turn off the motor 12 to stop the rotating shaft 11, and then stop the multiple fixed plates 20; place multiple reproductive medical embryo liquid nitrogen tanks 60 on the multiple side plates 22 on the fixed plate 20 respectively, so that the reproductive medical embryo liquid nitrogen tanks 60 are located between the two clamping arms 24.

[0041] The lifting block 21 is manually pressed downward to compress the spring 33. During the downward movement of the lifting block 21, the lifting block 21 drives the rack 34 to move downward, so that the rack 34 meshes with the gear 37 to drive the gear 37 to rotate clockwise, and the gear 37 drives the circular shaft 35 to rotate clockwise, and the torsion spring is deformed. During the clockwise rotation of the circular shaft 35, the circular shaft 35 drives the stop block 38 to rotate clockwise, so that the free end of the stop block 38 is away from the lower end of the lifting block 21. The lifting block 21 continues to move downward. Movement causes the rack 34 to separate from the gear 37, causing the round shaft 35 to rotate counterclockwise under the action of the torsion spring, and the round shaft 35 drives the stop block 38 to rotate counterclockwise, so that the free end of the stop block 38 slides into the stop groove 36, thereby realizing the positioning of the lifting block 21; when it is necessary to move the lifting block 21 upward, the round shaft 35 is manually rotated clockwise to make the free end of the stop block 38 move out of the stop groove 36, thereby allowing the lifting block 21 to move upward under the action of the spring 33.

[0042] During the downward movement of the lifting block 21, the lifting block 21 drives the transverse block 32 to move downward, and the transverse block 32 drives the clamping arm 24 to move obliquely downward along the path of the inclined groove 23 through the auxiliary block, so that the two transverse blocks 32 are close to each other, and the two clamping arms 24 are also close to each other, that is, the two clamping arms 24 are close to the reproductive medical embryo liquid nitrogen tank 60; the lifting block 21 continues to move downward, and when the lifting block 21 is positioned, the two clamping arms 24 clamp and position the reproductive medical embryo liquid nitrogen tank 60; therefore, when the lifting block 21 is positioned, multiple reproductive medical embryo liquid nitrogen tanks 60 on the fixed plate 20 can be clamped and positioned at the same time, which is easy to operate and effectively improves work efficiency.

[0043] During the period when the clamping arm 24 moves obliquely downward along the path of the inclined groove 23, the clamping arm 24 drives the movable block 42 to move synchronously, so that the movable rod 43 and the movable block 42 move laterally, that is, the two movable blocks 42 approach each other, and at the same time, the movable block 42 moves downward relative to the movable rod 43; during the period when the two movable blocks 42 approach each other, the two ends of the pressing block 40 also approach each other, thereby increasing the downward protrusion of the pressing block 40; at the same time, during the period when the movable block 42 moves downward relative to the movable rod 43, the movable block 42 drives the pressing block 40 to move downward at the same time, so that the protrusion of the pressing block 40 is against the top of the reproductive medical embryo liquid nitrogen tank 60, thereby achieving the compression of the reproductive medical embryo liquid nitrogen tank 60, and then enhancing the positioning effect of the reproductive medical embryo liquid nitrogen tank 60.

[0044] Repeat the above operation to complete the storage of multiple reproductive medical embryos in the liquid nitrogen tank 60 ; after the storage work is completed, manually drive the sealing plate 15 to slide in the opposite direction along the path of the arc groove 14 so that the sealing plate 15 seals the opening 13 .

[0045] In this embodiment, a handle 50 is fixedly connected to the circular shaft 35 ; the circular shaft 35 is driven to rotate by the handle 50 , which makes the operation easier.

[0046] In this embodiment, an elastic layer 51 is fixedly connected to the bottom of the pressing block 40, and the elastic layer 51 is a rubber layer; the elastic layer 51 replaces the pressing block 40 and abuts against the top of the reproductive medical embryo liquid nitrogen tank 60, so that damage to the reproductive medical embryo liquid nitrogen tank 60 can be avoided; and the pressing block 40 drives the elastic layer 51 to abut against the top of the reproductive medical embryo liquid nitrogen tank 60 so that the elastic layer 51 is deformed, which can increase the contact area between the elastic layer 51 and the top of the reproductive medical embryo liquid nitrogen tank 60, thereby enhancing the positioning effect of the reproductive medical embryo liquid nitrogen tank 60.

[0047] In this embodiment, a protrusion 52 is fixedly connected to the sealing plate 15 ; the sealing plate 15 is driven by the protrusion 52 to move along the path of the arc groove 14 , which makes the operation more convenient.

[0048] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
