Description
Technical Field
[0001] This utility model relates to the field of cold storage technology, specifically to a biomedical cold storage that is easy to recycle. Background Technology
[0002] Cold storage refers to an environment created artificially that differs from the outdoor temperature or humidity. It is a constant temperature and humidity storage device for items such as food, liquids, chemicals, pharmaceuticals, vaccines, and scientific experiments. In actual use, the internal temperature of biomedical cold storage is maintained at -80 degrees Celsius for a long time, thus meeting the storage requirements of most biomedical products. Biomedical cold storage needs to meet the storage requirements of biomedical products while also being efficient, flexible, and reliable to adapt to the turnover needs in different scenarios.
[0003] A search revealed a utility model patent with publication number CN217929356U, specifically disclosing a mobile cold storage unit, relating to the field of cold storage technology. The unit includes a cold storage shell, an air conditioner outdoor unit fixedly installed on the right outer wall, roller compartments on the left and right bottom sides of the shell, a partition plate movably installed inside the shell, a lifting motor fixedly installed on the top of the roller compartments, and a cold storage base fixedly installed at the four bottom corners of the shell. This utility model uses the rotation of a threaded rod to drive a movable shock-absorbing bracket to move up and down. The movable shock-absorbing bracket, connected to the roller bracket, causes the rollers to retract into the roller compartments. The cold storage unit is then placed on the ground via the bottom base. This solves the problem of increased transportation costs due to handling and refrigerated trucks during product transport, as well as the thawing losses during product handling, achieving cost savings and convenient transportation.
[0004] In the aforementioned patent, the rotation of the threaded rod drives the movable shock-absorbing bracket to move up and down. The movable shock-absorbing bracket, through its connection with the roller bracket, drives the rollers to retract into the roller compartment. The cold storage is placed on the ground via its bottom base, solving the problem of needing to use forklifts to transport products in the cold storage. However, biomedical cold storage is generally large in size, and during the turnover and movement of biomedical cold storage, the threaded rod drives the shock-absorbing bracket and rollers to move up and down. This requires the shock-absorbing bracket and threaded rod to have extremely high support strength, and the frequent up and down movement of the shock-absorbing bracket and threaded rod is prone to breakage, which may cause the cold storage to be bumped and damaged during turnover, resulting in damage to the equipment mounted on the outer wall of the cold storage.
[0005] Therefore, it is necessary to propose a biomedical cold storage that is easy to recycle to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a biomedical cold storage unit that is easy to move around. Through the cooperation of the internal parts of the traction mechanism, the traction rod can be connected and passed through the support base, releasing the rotation limit on the support shaft. Through the cooperation of the internal parts of the limiting mechanism, the support wheel can be limited, so that the limiting block passes through the support wheel and contacts the ground, thereby limiting the rotation of the support wheel. This completes the positioning of the cold storage unit after turnover, solving the problem that existing biomedical cold storage units are generally large in size, and that during the turnover process, the shock-absorbing bracket and rollers move up and down through the threaded rod. This requires the shock-absorbing bracket and threaded rod to have extremely high support strength, and the frequent up and down movement of the shock-absorbing bracket and threaded rod is prone to breakage, thus causing the cold storage to be bumped and damaged during turnover, resulting in damage to the equipment mounted on the outer wall of the cold storage.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a biomedical cold storage that is easy to recycle, comprising a cold storage body, a support base welded to the bottom end of the cold storage body, a traction mechanism threadedly connected to one end of the support base and extending into the interior of the support base, and a limit mechanism slidably connected inside the traction mechanism and extending into the outer wall of the traction mechanism.
[0008] The traction mechanism includes a traction rod, which is threaded to one end of the support base and extends into the interior of the support base. Support shafts are rotatably connected to both sides of the outer wall of the support base and extend into the interior of the support base. A support wheel is mechanically connected to the side of the support shaft away from the traction rod.
[0009] The limiting mechanism includes multiple connecting rods, which are slidably connected to the inside of the support shaft and located between the support wheels. A connecting column is machined on the side of each connecting rod away from the support wheel. A telescopic spring is sleeved on the outer wall of each connecting rod and located between the connecting column and the support shaft. A tapered column is machined on the side of each connecting rod away from the connecting column and extends into the inside of the support wheel. Multiple limiting blocks are slidably connected to the inner wall of the support wheel, fitting against one side of the inner wall of the tapered column and extending through the support wheel to its outer wall. A return spring is connected between one side of each limiting block and the inner wall of the support wheel. An arc-shaped baffle is rotatably connected to the outer wall of the support wheel and located at the end of the limiting block away from the tapered column. A connecting shaft is rotatably connected between the arc-shaped baffle and the support wheel and extends into the inside of the support wheel. A torsion spring is sleeved on the outer wall of the connecting shaft.
[0010] Preferably, the traction mechanism further includes an arc-shaped block, which is slidably connected to the inside of the support base and located below the traction rod. A support plate is machined at the bottom end of the arc-shaped block, and a fixing block is machined at the end of the support plate away from the arc-shaped block. The fixing block extends through the support base to the inside of the support shaft and is located between multiple connecting columns. A support spring is fixedly connected between the bottom end of the limiting block and the support base.
[0011] Preferably, one end of the support base is provided with a threaded hole that matches the traction rod, the bottom end of the cold storage body is provided with a movable groove that matches the support wheel, and the support shaft is rotatably connected to the support base through a bearing.
[0012] Preferably, the outer wall of the support shaft is provided with a plurality of fixing grooves that match the fixing block, the interior of the support base is provided with a support groove that matches the support plate, and the top of the arc block and the contact surface with the traction rod are set as an arc surface.
[0013] Preferably, a tapered surface matching the fixing block is provided between the plurality of connecting columns, an expansion groove matching the connecting rod is provided inside the support shaft, and a conical groove matching the limiting block is provided on the outer wall of the tapered column.
[0014] Preferably, the support wheel has a sliding groove inside that matches the limiting block, and a limiting plate that matches the reset spring is machined on one side of the limiting block. The two ends of the torsion spring are respectively connected to the connecting shaft and the support wheel, and the outer arc of the arc-shaped baffle is consistent with the outer wall of the support wheel.
[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0016] 1. By rotating the traction rod, the traction rod rotates through the threaded core into the support base. At the same time, the traction rod contacts the arc-shaped block and squeezes the arc-shaped block, causing the arc-shaped block to be forced to push the support plate to compress the support spring and move. This movement of the support plate drives the arc-shaped block and the fixed block to move, causing the fixed block to move out of the support shaft and release the limiting fixation on the support shaft. The operator drives the tractor connected to the traction rod and drives the moving support base through the traction rod, causing the support shaft to rotate and drive the support wheels to rotate. This allows the cold storage body to be moved and rotated flexibly.
[0017] 2. By allowing the fixed block to slide out from inside the support shaft, the fixed block releases its pressure on the connecting column, which in turn releases the pressure on the telescopic spring. The telescopic spring resets, pushing the connecting column to move, which in turn moves the connecting rod. The moving connecting rod then moves the conical column, releasing its pressure on the limiting block. The limiting block, in turn, releases its pressure on the reset spring via the limiting plate. This resets the spring, pushing the limiting block back from the outer wall of the support wheel to the inside of the support wheel, and also releases its pressure on the arc-shaped baffle. This resets the torsion spring, causing the connecting shaft to rotate. The rotation of the connecting shaft then causes the arc-shaped baffle to rotate, sealing the gap on the outer wall of the support wheel and releasing the locking and limiting of the support wheel to the ground. This allows the support wheel to rotate, enabling the cold storage unit to be transported and moved. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] This utility model provides, for example Figure 1-5 The present invention relates to a biomedical cold storage that is easy to recycle, comprising a cold storage body 1, a support base 101 welded to the bottom end of the cold storage body 1, a traction mechanism 2 threadedly connected to one end of the support base 101 and extending into the interior of the support base 101, and a limit mechanism 3 slidably connected inside the traction mechanism 2 and extending into the outer wall of the traction mechanism 2.
[0028] The traction mechanism 2 includes a traction rod 201, which is threaded to one end of the support base 101 and extends into the interior of the support base 101. Support shafts 202 are rotatably connected to both sides of the outer wall of the support base 101 and extend into the interior of the support base 101. A support wheel 203 is mechanically connected to the side of the support shaft 202 away from the traction rod 201.
[0029] The limiting mechanism 3 includes multiple connecting rods 301, which are slidably connected to the inside of the support shaft 202 and located between the support wheels 203. A connecting post 302 is machined on the side of the connecting rod 301 away from the support wheel 203. A telescopic spring 303 is sleeved on the outer wall of the connecting rod 301 and located between the connecting post 302 and the support shaft 202. A tapered post 304 is machined on the side of the connecting rod 301 away from the connecting post 302 and extends into the inside of the support wheel 203. Multiple connecting rods are slidably connected to the inner wall of the support wheel 203. A limiting block 305 is attached to one side of the inner wall of the conical column 304 and extends through the support wheel 203 to the outer wall of the support wheel 203. A return spring 306 is connected between one side of the limiting block 305 and the inner wall of the support wheel 203. An arc-shaped baffle 307 is rotatably connected to the outer wall of the support wheel 203 and is located at the end of the limiting block 305 away from the conical column 304. A connecting shaft 308 is rotatably connected between the arc-shaped baffle 307 and the support wheel 203 and extends through the interior of the support wheel 203. A torsion spring 309 is sleeved on the outer wall of the connecting shaft 308.
[0030] By cooperating with each other among the internal parts of the traction mechanism 2, the traction rod 201 can be connected and passed through the support base 101, and the rotation limit of the support shaft 202 can be released. By cooperating with each other among the internal parts of the limiting mechanism 3, the support wheel 203 can be limited, so that the limiting block 305 passes through the support wheel 203 and contacts the ground, thereby limiting the rotation of the support wheel 203, thus completing the positioning of the cold storage body 1 after turnover.
[0031] Refer to the instruction manual appendix Figure 1-5The traction mechanism 2 also includes an arc-shaped block 204, which is slidably connected to the inside of the support base 101 and located below the traction rod 201. A support plate 205 is machined at the bottom end of the arc-shaped block 204. A fixing block 206 is machined at the end of the support plate 205 away from the arc-shaped block 204 and passes through the support base 101 to the inside of the support shaft 202 and is located between multiple connecting columns 302. A support spring 207 is fixedly connected between the bottom end of the limiting block 305 and the support base 101. Through the mutual cooperation between the internal parts of the traction mechanism 2, the fixing block 206 can pass through the inside of the support shaft 202 to complete the rotation limit of the support shaft 202.
[0032] Refer to the instruction manual appendix Figure 1-5 One end of the support base 101 is provided with a threaded hole that matches the traction rod 201. The bottom end of the cold storage body 1 is provided with a movable groove that matches the support wheel 203. The support shaft 202 is rotatably connected to the support base 101 through a bearing. The threaded hole that matches the traction rod 201 at one end of the support base 101 facilitates the traction rod 201 to pass through the support base 101 and complete the connection between the traction rod 201 and the support base 101.
[0033] Refer to the instruction manual appendix Figure 1-5 The outer wall of the support shaft 202 is provided with multiple fixing grooves that match the fixing block 206. The inside of the support base 101 is provided with a support groove that matches the support plate 205. The top of the arc block 204 and the contact surface with the traction rod 201 are set as arc surfaces. The support groove inside the support base 101 that matches the support plate 205 and the top of the arc block 204 and the contact surface with the traction rod 201 are set as arc surfaces, so that the traction rod 201 can pass through the support base 101 and squeeze the arc block 204 to move.
[0034] Refer to the instruction manual appendix Figure 1-5 A tapered surface matching the fixing block 206 is provided between multiple connecting columns 302. The support shaft 202 has a telescopic groove matching the connecting rod 301 inside. The outer wall of the tapered column 304 has a conical groove matching the limiting block 305. The telescopic groove matching the connecting rod 301 inside the support shaft 202 and the conical groove matching the limiting block 305 on the outer wall of the tapered column 304 facilitate the telescopic movement of the connecting rod 301 to drive the tapered column 304 to squeeze the limiting block 305.
[0035] Refer to the instruction manual appendix Figure 1-5The support wheel 203 has a sliding groove inside that matches the limiting block 305, and a limiting plate that matches the return spring 306 is machined on one side of the limiting block 305. The two ends of the torsion spring 309 are connected to the connecting shaft 308 and the support wheel 203 respectively. The outer arc of the arc-shaped baffle 307 is consistent with the outer wall of the support wheel 203. The sliding groove inside the support wheel 203 matches the limiting block 305, and the limiting plate that matches the return spring 306 is machined on one side of the limiting block 305. This allows the limiting block 305 to squeeze the return spring 306 and move through the limiting plate, so that the limiting block 305 slides out from inside the support wheel 203 and contacts the ground, thus completing the limiting and fixing of the support wheel 203 on the ground.
[0036] The working principle of this practical application is as follows:
[0037] Refer to the instruction manual appendix Figure 1-5 By rotating the traction rod 201, the traction rod 201 rotates and passes through the thread into the support base 101. At the same time, the traction rod 201 contacts the arc-shaped block 204 and squeezes the arc-shaped block 204, causing the arc-shaped block 204 to be pushed by the force to push the support plate 205 to squeeze the support spring 207 to contract and move. This movement of the support plate 205 drives the arc-shaped block 204 and the fixed block 206 to move, causing the fixed block 206 to move out of the support shaft 202, releasing the limiting fixation of the support shaft 202. The staff drives the tractor vehicle and connects it to the traction rod 201, and drives the support base 101 to move through the traction rod 201. This causes the support shaft 202 to rotate and drive the support wheel 203 to rotate, thus moving and rotating the cold storage body 1, allowing the cold storage body 1 to be flexibly rotated.
[0038] Refer to the instruction manual appendix Figure 1-5 The fixing block 206 slides out from inside the support shaft 202, facilitating the release of the fixing block 206 from the compression of the connecting column 302. This releases the compression of the telescopic spring 303 by the connecting column 302, causing the telescopic spring 303 to reset and push the connecting column 302 to move, which in turn moves the connecting rod 301. The movement of the connecting rod 301 then moves the tapered column 304, causing the tapered column 304 to move and release the compression of the limiting block 305. The limiting block 305, in turn, releases the compression of the reset spring 306 through the limiting plate, thus allowing the reset spring to return to its original position. Spring 306 resets and pushes the limiting block 305 to retract from the outer wall of the support wheel 203 back into the support wheel 203, and releases the limiting block 305 from the pressure on the arc-shaped baffle 307. This causes the torsion spring 309 to reset and drive the connecting shaft 308 to rotate. The rotation of the connecting shaft 308 drives the arc-shaped baffle 307 to rotate, sealing and protecting the gap on the outer wall of the support wheel 203, and releasing the locking and limiting of the support wheel 203 to the ground. This allows the support wheel 203 to rotate and drive the cold storage body 1 for turnover and transportation.
[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
