Example 2:

referring to fig. 8 and 9, the present embodiment is different from embodiment 1 in that the supporting slider 63 is provided with an adjusting member 64 for controlling the vertical elevation of the storage box 1, so that when taking out or placing the vaccine bags, only the vertical elevation of the storage box 1 needs to be adjusted by the adjusting member 64, so that the storage box 1 as a whole can be placed on the top ends of the plurality of supporting screws 722.

Specifically, guide surfaces 631 are formed on both ends of the upper end surface of the support slider 63 in the longitudinal direction of the support rail 62. The guide surfaces 631 are disposed obliquely, and the high ends of the two guide surfaces 631 face each other. The adjusting member 64 includes two adjusting blocks 641 slidably disposed on the two guiding surfaces 631 in a one-to-one correspondence manner, and the two adjusting blocks 641 of the same adjusting member 64 are slidably connected to the first supporting block 61 along the length direction of the supporting rail 62.

Referring to fig. 9 and 10, the support slider 63 is provided with a control member 65 for controlling the two adjusting blocks 641 to slide away from each other. Of course, in other embodiments, the adjusting member 64 may be directly connected to the supporting slider 63 by using a hydraulic cylinder, and then the telescopic end of the adjusting member 64 may be fixedly connected to the first supporting block 61.

When the vaccine is subjected to temperature return treatment, the two adjusting blocks 641 are controlled to slide oppositely only by the control member 65, so that the adjusting blocks 641 slide upwards along the guide surface 631, and the first supporting block 61 is lifted, so that the overall height of the storage box 1 is increased, the height of the storage box 1 can be adapted to the rotation of the swinging block 51, and the possibility of interference between the storage box 1 and the supporting screw 722 is reduced; when the vaccine bags need to be taken out or placed, the two adjusting blocks 641 are controlled to slide away from each other only by the control member 65, so as to reduce the height of the storage box 1, and the storage box 1 is parked at the upper ends of the plurality of supporting screws 722; compared with the way of controlling the storage box 1 to ascend and descend directly by a hydraulic cylinder, the impact generated by the adjusting block 641 when the storage box 1 swings can be partially decomposed into a component force in the horizontal direction by the guide surface 631, so that the vertical direct impact can be effectively reduced, and the stability of the storage box 1 when swinging is maintained.

Referring to fig. 9 and 10, further, the first supporting block 61 is fixedly connected to at least one first guiding strip 611, the cross section of the first guiding strip 611 is dovetail-shaped or T-shaped, and the first guiding strip 611 is clamped in sliding grooves formed in the two adjusting blocks 641, so that the first supporting block 61 is slidably connected to the adjusting blocks 641, and the adjusting blocks 641 and the first supporting block 61 can slide to adapt to the swing of the storage box 1 and reduce the possibility that the storage box 1 is separated from the adjusting blocks 641.

The control piece 65 includes a control screw 651 and two control sliders 652, the control screw 651 is a double-threaded screw, two ends of the control screw 651 are respectively penetrated and threaded to the control sliders 652, so that when the control screw 651 rotates, the two control sliders 652 can be driven to slide in opposite directions and move away from the sliding.

Referring to fig. 9 and 10, in particular, the supporting slider 63 is provided with a mounting sliding cavity 632, and the control screw 651 is rotatably disposed in the mounting sliding cavity 632, and is parallel to the supporting rail 62. The control slider 652 is slidably connected to the mounting sliding cavity 632 along the length direction of the support rail 62, and a vertically extending control bar 653 is fixedly connected to the control slider 652. Two control ports 633 that all vertically extend and communicate with installation sliding chamber 632 are seted up to support slider 63, and two control bars 653 vertically wear to locate control port 633 and insert and locate adjusting block 641 one-to-one respectively, and the profile of control port 633 is rectangular shape to make control bar 653 can follow control slider 652 and slide along control port 633.

When the height of the storage box 1 needs to be adjusted, the control screw 651 is only required to be controlled to rotate, so that the two control sliders 652 slide in the opposite direction or away from each other, and the control strip 653 is vertically inserted into the adjusting block 641, so that the two adjusting blocks 641 are driven to slide in the opposite direction or away from each other, the first supporting block 61 is vertically lifted, and the height of the storage box 1 is adjusted; in the process, the impact force generated by the swinging of the storage box 1 and the force in the horizontal direction generated by the guide surface 631 can be borne by the control screw 651, so that the borne impact force can be effectively reduced, the stability in use is optimized, and the possibility of damage to the control screw 651 in use is reduced; compared with the vertical lifting control of the first supporting block 61 directly controlled by the electric pushing cylinder and the hydraulic cylinder, the possibility that the vertical lifting control component is damaged can be effectively reduced; so as to optimize the possibility of damage to the control member 65 while reducing the occurrence of local overheating of the vaccine bag by the oscillation.

Referring to fig. 9 and 10, the supporting slide 63 is further provided with a power member 66 for driving the control screw 651 to rotate, the power member 66 comprises a power worm wheel 661, a power worm 662 engaged with the power worm wheel 661, and a power motor 663 for driving the power worm 662 to rotate, and the power motor 663 is fixedly connected to the supporting slide 63. The power worm 662 is coaxially and fixedly connected to an output shaft of the power motor 663. The control screw 651 coaxially penetrates through and is fixedly connected to the power worm wheel 661, and the power worm wheel 661 is located between the two control sliders 652.

The implementation principle of the embodiment 2 is as follows: when the storage box 1 needs to be controlled to vertically lift, only the power worm 662 and the power worm wheel 661 need to be driven to rotate through the power motor 663, so that the control screw 651 is driven to rotate, and when the storage box 1 swings, the control screw 651 can also be arranged in a penetrating manner and connected with the control slide block 652 and the power worm wheel 661 in a threaded manner to be meshed with the power worm 662 to realize multiple passive rotation locking, so that the stability during the use is further optimized, the rotation of the control screw 651 caused by impact force is reduced, and the possibility of interference between the storage box 1 and the support screw 722 is realized.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
