[0006] As a preferred embodiment, the mounting boss includes a mounting base, a vertical rod on the mounting base, a guide boss on the vertical rod, and a mounting recess including a mounting post connected to a telescopic rod. The mounting post has a mounting groove into which the guide boss extends. A locking pin is radially telescopically installed in the mounting groove. The free end of the locking pin is divided into an upper contact surface and a lower contact surface. The lower contact surface contacts and guides the upper part of the guide boss, while the upper contact surface contacts and supports the lower part of the guide boss.

[0007] As a preferred embodiment, the quick-release structure includes a guide ring, which is movably fitted onto a vertical rod. The mounting base and guide boss limit the range of motion of the guide ring. The upper part of the guide ring fits against the lower part of the guide boss, forming a smooth transition between the lower part of the guide ring and the upper part of the guide boss. The lower contact surface of the pin contacts and guides the upper part of the guide ring, and the upper contact surface of the pin contacts and guides the lower part of the guide ring.

[0008] As a preferred embodiment, the auxiliary opening structure includes a mounting plate fixedly connected to the carding device. Multiple auxiliary suction cups are vertically connected and mounted on the mounting plate via suction cup connecting rods. The top end of the suction cup connecting rods is provided with a negative pressure suction port connected to a negative pressure system. The suction cup connecting rods pass through the mounting plate and slide vertically up and down.

[0009] As a preferred embodiment, the locking post has a pin hole in which the locking pin slides radially horizontally, and a fixing plate is provided on the outside of the locking post to block the pin hole. The rod of the locking pin passes through the fixing plate and slides horizontally. A return spring is fitted on the rod of the locking pin, and the return spring is limited by the fixing plate and the end of the locking pin.

[0010] As a preferred embodiment, the upper contact surface of the pin is a horizontal surface, the lower contact surface of the pin is an inclined surface, the lower part of the guide boss is also a horizontal surface, and the lower part of the guide ring is an arc surface or an inclined surface.

[0011] As a preferred embodiment, the upper part of the guide boss is an arc surface or an inclined surface, and the upper part of the guide ring is a horizontal surface.

[0012] As a preferred embodiment, the mounting plate is rectangular, and two auxiliary suction cups are provided and symmetrically mounted on the mounting plate with the clamping post as the center.

[0013] As a preferred embodiment, the cover plate is also provided with a positioning structure for quick positioning with the opening of the storage pool.

[0014] After adopting the above technical solution, the effect of this utility model is as follows: The human specimen storage pool cover opening mechanism includes multiple storage pools arranged in an array. A cover is installed at the upper end of each storage pool. The cover has a locking protrusion, and a locking recess is provided above the locking protrusion for locking and fixing with it. The locking recess is connected to a lifting device via a telescopic rod. The telescopic rod also has an auxiliary opening structure to limit the deflection of the cover when opening. Furthermore, there is a connection between the locking recess and the locking protrusion. Equipped with a quick-release structure, the telescopic rod is moved above the locking protrusion via a lifting device. The telescopic rod then extends, causing the locking protrusion to descend and engage with the locking recess. Simultaneously, an auxiliary opening structure assists in stabilizing the opening of the cover. The cover is then moved, and after movement, the quick-release structure allows for the disassembly of the locking recess and protrusion, enabling subsequent operations. This opening mechanism accurately moves the cover through the engaging and disassembling of the locking protrusion and recess, facilitating easy disassembly. Its simple structure reduces operating costs.

[0015] Furthermore, the mounting protrusion includes a mounting base, a vertical rod on the mounting base, a guide protrusion on the vertical rod, and a mounting recess including a mounting post connected to a telescopic rod. The mounting post has a mounting groove into which the guide protrusion extends. A locking pin is radially telescopically installed within the mounting groove. The free end of the locking pin is divided into an upper contact surface and a lower contact surface. The lower contact surface contacts and guides the upper part of the guide protrusion, while the upper contact surface contacts and supports the lower part of the guide protrusion. Fixing the vertical rod and guide protrusion to the cover plate via the mounting base ensures stable and reliable movement of the cover plate by clamping the guide protrusion. Simultaneously, when the mounting post descends, it ensures that the locking pin is accurately guided and compressed back by the guide protrusion. When moving downwards again, it is positioned at the vertical rod, and the locking pin extends again. Then, when the mounting post rises, the locking pin presses against the lower part of the guide protrusion, thereby driving the cover plate to rise and move, ensuring stable and reliable operation.

[0016] Furthermore, the quick-release structure includes a guide ring, which is movably fitted onto the vertical rod. The locking base and guide boss restrict the range of motion of the guide ring. The upper part of the guide ring fits against the lower part of the guide boss, creating a smooth transition between the lower part of the guide ring and the upper part of the guide boss. The lower contact surface of the pin contacts and guides the upper part of the guide ring, while the upper contact surface of the pin contacts and guides the lower part of the guide ring. When the cover plate needs to be lowered, the locking post is moved downwards, and the lower contact surface of the locking pin contacts the upper part of the guide ring. The guide ring is then held in place by the locking base, causing the locking pin to be squeezed back again, placing it below the guide ring. Then, the locking post is raised, and the upper contact surface of the locking pin drives the guide ring to rise until it contacts the guide boss. As it continues to rise, the upper contact surface of the locking pin is guided by the lower part of the guide ring, squeezing it back. Simultaneously, the guide ring and guide boss smoothly transition, and the locking pin remains in the retracted state until it disengages from the guide boss, completing the removal of the cover plate. The operation is simple and convenient.

[0017] Furthermore, the auxiliary cover opening structure includes a mounting plate fixedly connected to the clamping device. Multiple auxiliary suction cups are vertically connected and installed on the mounting plate via suction cup connecting rods. The top of the suction cup connecting rods is provided with a negative pressure suction port connected to the negative pressure system. The suction cup connecting rods pass through the mounting plate and slide vertically up and down. The installation height of the auxiliary suction cups is lower than the installation height of the clamping column. The auxiliary suction cups on the mounting plate can first suction the cover plate to prevent the cover plate from moving, thereby improving the stability of the cover plate when it moves.

[0018] Furthermore, the locking pin has a pin hole that allows it to slide horizontally in the radial direction within the locking pin, and a fixing plate that blocks the pin hole is located on the outside of the locking pin. The rod of the locking pin passes through the fixing plate and slides horizontally. A return spring is fitted onto the rod of the locking pin, and the return spring is limited by the fixing plate and the end of the locking pin. The rod of the locking pin passing through the fixing plate ensures that the locking is stable and reliable when it is compressed and extended, and also ensures that the locking pin is fixed stably and reliably when it is supported by the guide boss. The return spring ensures that the locking pin can be accurately ejected after being compressed.

[0019] Furthermore, since the upper contact surface of the pin is a horizontal plane, the lower contact surface of the pin is an inclined slope, the lower part of the guide boss is also a horizontal plane, and the lower part of the guide ring is an arc surface or an inclined slope; thus, when the locking pin descends, the lower contact surface of the pin will be squeezed by the inclined slope, causing the locking pin to retract and the locking post to descend. Then, the upper contact surface of the pin and the lower part of the guide boss can effectively fit together, and the locking pin will not retract, effectively supporting the guide boss stably and reliably, thereby causing the cover plate to rise; then, when disassembly is required, the lower part of the guide ring can easily squeeze the locking pin when it contacts the upper contact surface of the pin, and at the same time, the guide ring moves towards the guide boss, ensuring that the upper contact surface of the pin can be stably guided and squeezed when it is facing upward.

[0020] Furthermore, since the upper part of the guide boss is an arc surface or an inclined surface, and the upper part of the guide ring is a horizontal surface, the upper part of the guide boss can reduce friction when it contacts the locking pin, and the guiding compression is accurate. The upper part of the guide ring can fit better with the lower part of the guide boss, making it easier for the locking rod to transition from the guide ring to the guide boss.

[0021] Furthermore, since the mounting plate is rectangular, two auxiliary suction cups are provided and symmetrically mounted on the mounting plate with the clamping post as the center; using as few auxiliary suction cups as possible ensures the stability when moving the cover plate and improves the usage effect.

[0022] Furthermore, the cover plate is also equipped with a positioning structure for quick positioning with the opening of the storage pool, ensuring that the cover plate can be accurately closed when it is moved back onto the storage pool. Attached Figure Description

[0032] The present invention will be further described in detail below through specific embodiments.

[0033] like Figures 1 to 7 As shown, a human specimen storage pool cover opening mechanism includes a storage pool 1, wherein there are multiple storage pools 1 arranged in an array, and a cover plate 2 is installed on the upper end of the storage pool 1. The cover plate 2 is provided with a locking protrusion, and a locking recess is provided above the locking protrusion to lock and fix with the locking protrusion. The locking recess is connected to a lifting device through a telescopic rod 3. The telescopic rod 3 is also provided with an auxiliary opening structure to limit the deflection of the cover plate when opening the cover. A quick-release structure is also provided between the locking recess and the locking protrusion.

[0034] In this embodiment, the lifting device includes a linear sliding block and a telescopic rod 3 fixed on the linear sliding block. The linear sliding block can change the horizontal position of the telescopic rod 3. The telescopic rod 3 is connected to a locking recess to change its height. The same structure is described in patent number 202410550920.4, so it will not be described in detail in this document.

[0035] like Figure 2 and Figure 3 As shown, the mounting boss includes a mounting base 4, a vertical rod 5 on the mounting base 4, a guide boss 6 on the vertical rod 5, and a mounting recess including a mounting post 7 connected to the telescopic rod 3. The mounting post 7 has a mounting groove 8 for the guide boss 6 to extend into. A locking pin 9 is radially telescopically mounted within the mounting groove 8. The free end of the locking pin 9 is divided into an upper contact surface 10 and a lower contact surface 11. The lower contact surface 11 contacts and guides the upper part of the guide boss 6, while the upper contact surface 10 contacts and guides the lower part of the guide boss 6. The guide boss 6 is supported by a clamping base 4. The clamping base 4, the vertical rod 5 and the guide boss 6 are fixedly fixed to form a clamping boss, and each cover plate 2 is fixedly installed with the clamping boss. This ensures that the cover plate 2 can be moved stably and reliably by clamping the guide boss 6. At the same time, when the clamping post 7 descends, it can ensure that the locking pin 9 is accurately guided and squeezed back by the guide boss 6. When it moves downward, it is located at the vertical rod 5, and the locking pin 9 will extend again. Then the clamping post 7 rises, and the locking pin 9 will push against the lower part of the guide boss 6, thereby driving the cover plate 2 to rise and move, forming a rigid connection, which is stable and reliable in use.

[0036] Furthermore, the quick-release structure includes a guide ring 12, which is movably fitted onto the vertical rod 5. The locking base 4 and the guide boss 6 restrict the range of motion of the guide ring 12. The upper part of the guide ring 12 fits against the lower part of the guide boss 6, forming a smooth transition between the lower part of the guide ring 12 and the upper part of the guide boss 6. The pin lower contact surface 11 contacts and guides the upper part of the guide ring 12, and the pin upper contact surface 10 contacts and guides the lower part of the guide ring 12. The guide ring 12 can move up and down along the vertical rod 5. When the cover plate 2 has been moved and needs to be disassembled and placed, the locking pin 7 is moved further down to lock the pin 9. The lower contact surface 11 of the pin contacts the upper part of the guide ring 12, and the guide ring 12 is held in place by the mounting base 4, thereby squeezing and compressing the locking pin 9 back, so that the locking pin 9 is below the guide ring 12. Then, the mounting post 7 is raised, and the upper contact surface 10 of the locking pin 9 drives the guide ring 12 to rise until it contacts the guide boss 6. As it continues to rise, the upper contact surface 10 of the locking pin 9 is guided by the lower part of the guide ring 12 and squeezed and compressed back. At the same time, the guide ring 12 and the guide boss 6 smoothly transition, and the locking pin 9 remains in the retracted state until it is disengaged from the guide boss 6. This completes the disassembly of the cover plate 2. The operation is simple and convenient.

[0037] like Figure 1 and Figure 7 As shown, the auxiliary cover opening structure includes a mounting plate 13 fixedly connected to the locking device. Multiple auxiliary suction cups 14 are vertically connected and installed on the mounting plate 13 via suction cup connecting rods 15. The top end of the suction cup connecting rods 15 is provided with a negative pressure suction port 16 connected to the negative pressure system. The suction cup connecting rods 15 pass through the mounting plate 13 and slide vertically up and down. The auxiliary suction cups 14 on the mounting plate 13 can first suck up the cover plate 2 and prevent the cover plate 2 from moving, thereby improving the stability of the cover plate 2 when it moves.

[0038] In this embodiment, the locking post 7 has a pin hole 17 for the locking pin 9 to slide horizontally in the radial direction. The locking post 7 has a fixing plate 18 on the outside to block the pin hole. The rod of the locking pin 9 passes through the fixing plate 18 and slides horizontally. The rod of the locking pin 9 is fitted with a return spring 19. The return spring 19 is limited by the fixing plate 18 and the end of the locking pin 9. The rod of the locking pin 9 passing through the fixing plate 18 can ensure that the locking is stable and reliable when it is squeezed and stretched. At the same time, it can also ensure that the locking pin 9 is fixed stably and reliably when it is supported by the guide boss 6. The return spring 19 can ensure that the locking pin 9 can be accurately ejected after being squeezed.

[0039] like Figure 4 and Figure 5As shown, the upper contact surface 10 of the pin is a horizontal surface, the lower contact surface 11 of the pin is an inclined surface, the lower part of the guide boss 6 is also a horizontal surface, and the lower part of the guide ring 12 is an arc surface or an inclined surface. In this way, when the locking pin 9 descends, the lower contact surface 11 of the pin will be squeezed by the inclined surface, causing the locking pin 9 to retract and the locking post 7 to descend. Then, the upper contact surface 10 of the pin and the lower part of the guide boss 6 can effectively fit together, and the locking pin 9 will not retract, effectively supporting the guide boss 6 stably and reliably, thereby causing the cover plate 2 to rise. Then, when disassembly is required, the lower part of the guide ring 12 can easily squeeze the locking pin 9 when it comes into contact with the upper contact surface 10 of the pin. At the same time, the guide ring 12 moves towards the guide boss 6 to ensure that the upper contact surface 10 of the pin can be stably guided and squeezed when it rises.

[0040] In this embodiment, the upper part of the guide boss 6 is an arc surface or an inclined surface, and the upper part of the guide ring 12 is a horizontal surface; when the upper part of the guide boss 6 contacts the locking pin 9, friction can be reduced and the guiding compression is accurate. The upper part of the guide ring 12 can fit better with the lower part of the guide boss 6, which facilitates the transition of the locking rod from the guide ring 12 to the guide boss 6, making disassembly more accurate and reliable.

[0041] In this embodiment, the mounting plate 13 is rectangular, and two auxiliary suction cups 14 are provided and symmetrically mounted on the mounting plate 13 with the clamping post 7 as the center; using as few auxiliary suction cups 14 as possible ensures the stability of the cover plate 2 when moving, prevents the cover plate 2 from rotating after being lifted, and improves the use effect.

[0042] like Figure 6 As shown, the cover plate 2 is also provided with a positioning structure for quick positioning with the opening of the storage tank 1; the positioning structure is a sealing block 20 with a trapezoidal cross section fixedly installed below the cover plate 2. The inclined surface of the sealing block 20 can effectively guide the cover plate 2 to slide accurately when it is moved to the opening of the storage tank 1, ensuring accurate sealing and improving the use effect.

[0043] The working principle of this embodiment is as follows: First, the telescopic rod 3 is moved to the upper part of the corresponding storage tank 1 by the linear sliding block. Then, the telescopic rod 3 drives the locking post 7 to descend. The auxiliary suction cup 14 first contacts the cover plate 2 for adsorption. Then, the guide boss 6 is inserted into the locking groove 8. When the locking pin 9 contacts the guide boss 6, the lower contact surface 11 of the pin and the upper part of the guide boss 6 are squeezed and guided, the locking pin 9 retracts, and the locking post 7 falls below the guide boss 6. Then, after the locking pin 9 pops out, the locking post 7 rises, and the locking pin 9 pushes up the guide boss 6. Platform 6 opens cover 2. After moving cover 2, when it is necessary to remove cover 2, the locking post 7 continues to descend, causing the locking pin 9 to contact the guide ring 12. After pressing down the guide ring 12, the locking pin 9 retracts and descends. The locking pin 9 pops out and is below the guide ring 12. Then, it drives the guide ring 12 to rise and approach the guide boss 6. Then, the locking pin 9 squeezes the lower part of the guide ring 12 and retracts again. It transitions along the lower part of the guide ring 12 to the upper part of the guide boss 6, and finally pops out. The auxiliary suction cup 14 releases the suction, and the disassembly is completed.

[0044] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and alterations made to the technical solution of the present utility model without departing from its design spirit shall fall within the protection scope defined by the claims of the present utility model.
