Description

Technical Field

[0001] The invention relates to the technical field of cold storage, in particular to a constant temperature refrigerator for beef cattle semen which is convenient to take out. Background Art

[0002] A constant temperature refrigerator is a special type of refrigerator that can maintain a constant temperature. It is usually used to store temperature-sensitive items such as medicines, chemical reagents, food, biological samples and experimental materials. It has a precise temperature control system that can maintain stability within the set temperature range.

[0003] A biological sample is any biological material obtained from an organism, including blood, tissue, cells, semen, urine, saliva, skin, hair, DNA or RNA. The collection and analysis of biological samples is crucial for understanding disease mechanisms, conducting genetic research, assessing health status, and developing new drugs and treatments. In a laboratory environment, these samples often need to be stored in a constant temperature refrigerator to maintain their stability and suitability.

[0004] At present, when studying the semen of beef cattle, it is necessary to put the collected semen into antifreeze test tubes, add cryoprotectants into the test tubes, and then place the test tubes in a constant temperature refrigerator for storage. However, during the storage process, the protective agent will tend to precipitate and stratify in a static state, and the semen will also have tiny precipitates and clots. Regular slight swinging is required to reduce the occurrence of these phenomena. As for the swinging of the test tubes, the experimenters usually take the test tubes out of the refrigerator one by one in strict accordance with the prescribed time and swing them. However, this method is cumbersome to operate and takes a long time. At the same time, the different swinging times of the test tubes in the front and back sequences will also lead to inaccurate experimental data. Summary of the invention

[0069] The swing assembly 4 also includes two support rods 404 and two connecting rods 408 installed in the constant temperature room. The two support rods 404 are respectively fixed on the rotating knobs 403 in each layer of the guide assembly 3. The two connecting rods 408 pass through the moving blocks 406 in each layer of the guide assembly 3. A spring latch 407 is installed on one side of the moving block 406. A plurality of latch holes 409 are provided on the surface of the connecting rod 408 along its length direction. The output end of the spring latch 407 is plugged into one of the latch holes 409 (this state is linked locking), and any locked placement assembly 2 is swung up and down, thereby driving the locked placement assembly 2 to swing at the same time.

[0070] Several drivers 5 are installed in the constant temperature room along the length direction thereof. The drivers 5 are located at the end of the inner slide rail 301 and are used to drive the strip plate 202 to swing in the storage state.

[0071] A regulating groove 412 is provided on one side of the connecting plate 401 away from the outer slide rail 302. The regulating groove 412 is connected to the stabilizing groove 405. A regulating slider 413 is slidably connected in the regulating groove 412. The regulating slider 413 is L-shaped. A push rod 414 is fixed to one end of the regulating slider 413 adjacent to the spring latch 407.

[0072] When the placement component 2 is in a horizontal state, the push rod 414 can correspond to the spring latch 407 . When the regulating slider 413 is pushed, the push rod 414 pushes the end of the spring latch 407 , so that the front end of the latch is inserted into the latch hole 409 .

[0073] The spring latch 407 is a push-type spring latch 407. When pushed for the first time, the front end of the latch can be inserted into the latch hole 409, and when pressed again, the latch is disengaged from the latch hole 409, thereby realizing the alternating locking and unlocking effects (this component is an existing technology, but is not limited to this component. Any component that can achieve the above function is acceptable, and no limitation is made here).

[0074] A protrusion 415 is fixed to the side of the regulating slider 413 away from the outer slide rail 302, a connecting rod 417 is fixed to one end of the protrusion 415, a right-angle plate 418 is fixed to one end of the connecting rod 417, a toothed plate 419 is fixed to one end of the right-angle plate 418, and at the same time, the tail end of the inner slide rail 301 is rotatably connected to a rotating gear 311, a gear roller 1 312 is fixed to the rotating gear 311, and the sides of the gear roller 1 312 and the gear roller 2 309 are meshed with a conductive toothed belt 313.

When the regulating slider 413 is pulled outward, the latch rod 416 is inserted into the positioning block 101 to achieve horizontal fixation of the swing assembly 4. At this time, the placement assembly 2 can be pulled and moved by the inner and outer slide rails, but cannot achieve the effect of swinging up and down.

[0078] A spring button 420 is fixed to the end of the tooth plate 419 , and a docking plate 315 is provided at the end of the inner slide rail 301 .

[0079] A circular hole is provided on the docking plate 315, and the spring button 420 is horizontally opposite to the circular hole.

[0080] Both ends of the linkage rod 408 are sleeved with sleeve rods 4081 , one end of the sleeve rod 4081 is installed in the constant temperature chamber, and the side of the sleeve rod 4081 is sleeved with a tension spring 4082 .

[0081] The sleeve rods 4081 at both ends of the connecting rod 408 are respectively fixed at the corresponding positions of the top and bottom in the constant temperature chamber, so that the connecting rod 408 can move smoothly in the vertical direction and, under the push of the tension spring 4082, improve the portability of the swing assembly 4 when swinging.

[0082] The working principle of the convenient-to-access constant-temperature refrigerator for beef cattle semen proposed in this embodiment is: when in use, by pushing the regulating slider 413, the latch rod 416 disengages from the positioning block 101, so that the spring latch 407 is inserted into the latch hole 409, and the linked locking is realized. At the same time, the tooth plate 419 moves backward, so that the baffle 310 flips outward and fits on the side of the synchronization rod 308, and synchronous locking is realized. At the same time, the spring button 420 disengages from the round hole of the docking plate 315. At this time, pull the placement component 2 of any locking layer to realize the extraction of the placement component 2 of the locking layer and the display of the test tube. At the same time, it can swing up and down to shake the semen in the test tube to avoid precipitation.

[0083] Example 2: Please refer to Figure 16-17 As shown, the convenient-to-use constant-temperature refrigerator for beef cattle semen proposed in this embodiment, based on the first embodiment, also includes that a sprocket 204 is fixed on the strip plate 202, and a chain belt 205 is meshed on the side of the sprocket 204, one end of the sprocket 204 is rotatably connected to the inner slide rail 301, wherein a transmission gear 1 206 is fixed on the sprocket 204 near one end of the inner slide rail 301, wherein a transmission gear 2 207 is fixed on the sprocket 204 near the other end of the inner slide rail 301, and a driving gear 303 is rotatably connected to one end of the inner slide rail 301 near the transmission gear 1 206, and the driving gear 303 is meshed with the transmission gear 1 206.

[0084] The chain belt 205 is wavy-shaped and mounted on a plurality of sprocket wheels 204, so that the sprocket wheels 204 can rotate simultaneously, realizing the effect of swinging or tilting the strip plate 202. The driving gear 303 drives the transmission gear 1 206 to rotate, so that a plurality of sprocket wheels 204 rotate simultaneously, realizing the effect of the strip plate 202 driving the test tube to tilt.

[0085] A connecting groove 304 is formed at one end of the inner slide rail 301 close to the driving gear 303 , a rack 305 is arranged in the outer slide rail 302 , and a plurality of friction plates 306 are fixed in the inner slide rail 301 , and the friction plates 306 are attached to the side of the sprocket 204 .

[0086] A rack 305 is fixed at one end of the outer slide rail 302, and the rack 305 and the connecting groove 304 are arranged in parallel and staggered along the length direction of the slide rail. When the inner slide rail 301 is pulled outward, the driving gear 303 meshes and rotates on the rack 305, and the driving gear 303 drives the connected sprocket 204 to rotate, and under the transmission of the chain belt 205, the multiple strip plates 202 drive the test tubes to be tilted and displayed.

[0087] It should be further explained that when the transmission gear 504 is meshed with the second transmission gear 207 , the driving gear 303 cannot be meshed with the rack 305 .

[0089] When the inner and outer slide rails are completely closed, the stabilizing groove 507 can fit on the side of the transmission gear 207, and the transmission gear 504 can mesh with the transmission gear 207. The output end of the driving motor 502 has the function of bidirectional rotation. During operation, the output end drives the motor gear 1 503 to rotate. Under the transmission of the transmission toothed belt 506, the motor gear 2 505 drives the transmission gear 504 to rotate, and when the transmission gear 504 is meshed with the transmission gear 207, it can drive the corresponding installed sprocket 204 to rotate, and under the transmission of the chain belt 205, multiple sprockets 204 drive the strip plate 202 to swing, so that the test tube can remain in a shaking state during storage to avoid precipitation.

[0090] The swing assembly 4 also includes an upper auxiliary plate 421 and a lower auxiliary plate 422. Both the upper and lower auxiliary plates are fixed to the outer slide rail 302. The upper auxiliary plate 421 is located above the front end of the connecting plate 401, and the lower auxiliary plate 422 is located below the front end of the connecting plate 401. The upper and lower auxiliary plates have different horizontal distances relative to the outer frame 201.

[0091] The upper auxiliary plate 421 is fixed above the front end of the outer slide rail 302, while the lower auxiliary plate 422 is fixed below the front end of the outer slide rail 302, and they are staggered in the vertical direction.

[0092] The adjacent surfaces of the upper and lower auxiliary plates are inclined. When the placement component 2 is pulled out, the bottom of the test tube that is in contact with the inclined surface of the lower auxiliary plate 422 gradually moves upward from the test tube slot 203, making it easier to check the test tube label. When the placement component 2 is retracted into the constant temperature chamber, the top of the test tube that is in contact with the inclined surface of the upper auxiliary plate 421 gradually retracts downward into the test tube slot 203.

[0093] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
