The utility model provides a mechanism for opening, closing and flipping a refrigeration module side door 14, including a refrigeration bin 1 and a side door 14, and also includes a linear guide slider assembly, a synchronous belt drive assembly and a crank slider assembly. The synchronous belt drive assembly includes two identical synchronous pulleys 7, a synchronous belt 10, a bearing baffle 3, a bearing 4, a first rotating shaft 5, an adjustable pulley bearing seat 6, a synchronous belt adjusting screw 8, and a synchronous belt drive assembly. The step belt connecting plate 9, the synchronous belt locking plate 11, the pulley shaft seat 12 and the pulley shaft seat mounting plate 30, the linear guide slider assembly includes a side door connecting plate 13, a guide rail mounting plate 20, a guide rail 26, a slider 25, a slider mounting plate 24 and a slider fixed mounting plate 23, the crank slider assembly includes an inclined plane mechanism and a torsion spring 16, the inclined plane mechanism includes a reagent bottle seat 2, an axle seat 15, a second rotating shaft 17, a warehouse door rotating lever 18, a nut 19, a warehouse door flip trigger inclined plane 21, an inclined plane mounting plate 22 and a bearing retaining ring 27.

[0027] In this embodiment, the utility model sets the synchronous belt drive assembly, so that the damping of the pulling and pushing action of the reagent bottle holder can be adjusted, thereby realizing the adjustable operation feel of the operator, and by setting the linear guide slider assembly and the crank slider assembly, when replacing the reagent in the reagent bottle in the refrigeration module, the reagent bottle holder can be pulled out a suitable distance and then flipped, which can be more convenient for the operator to take the reagent bottle when replacing the reagent in the reagent bottle, thereby solving the technical problems that the reagent bottles in the refrigeration module of the existing blood cell analysis and specific protein analysis all-in-one machine are difficult to replace when replacing the reagent, the pulling of the reagent bottle holder is not smooth, and the resistance cannot be adjusted.

[0028] Among them, the side door 14 is arranged on one side of the refrigeration warehouse 1, and is used to close or open and close the refrigeration warehouse 1. The linear guide slider assembly is used to translate and pull out the side door 14, so as to realize the pulling and pushing operation of the reagent bottle holder of the refrigeration module. The synchronous belt drive assembly is used to adjust the damping of the pulling and pushing action of the reagent bottle holder to realize the adjustable operation feel of the operator. Through the coordinated use of the inclined plane mechanism and the torsion spring 16, the flipping movement of the reagent bottle holder based on the translation of the linear guide slider assembly is realized.

[0029] Secondly, the synchronous belt transmission assembly is externally connected to a driving motor for converting the manual operation of the synchronous belt transmission assembly into motor drive to achieve automated operation.

[0030] Again, the synchronous belt adjusting screw 8 is directly stuck in the U-shaped groove of the pulley shaft seat mounting plate 30, and the synchronous belt adjusting screw 8 is screwed into the adjustable pulley bearing seat 6, and the adjustable pulley bearing seat 6 is arranged on the pulley shaft seat mounting plate 30; when assembling the synchronous pulley 7, one of the bearings 4 is installed in the adjustable pulley bearing seat 6 and the pulley shaft seat 12, and then the first rotating shaft 5 is passed through the circular hole of the synchronous pulley 7 along the hole, and the axial end of the first rotating shaft 5 is installed in the bearing 4, and then the other bearing 4 is installed into the other end of the first rotating shaft 5, and finally the bearing baffle 3 is stuck in the slot on the first rotating shaft 5. According to the different requirements of different operators for experience, the tightness of the synchronous belt 10 is adjusted by the synchronous belt adjusting screw 8.

[0031] At the same time, the adjustable pulley bearing seat 6 and the pulley shaft seat 12 are both installed on the pulley shaft seat mounting plate 30, and a guide structure for moving along the linear guide slider assembly is set between the adjustable pulley bearing seat 6 and the pulley shaft seat mounting plate 30.

[0032] In addition, for the synchronous belt connecting plate 9, the structural design needs to ensure that the synchronous belt connecting plate 9 can smoothly pass through the synchronous belt pulley 7 and the adjustable pulley bearing seat 6.

[0033] In addition, the side door connecting plate 13 is connected to the side door 14, and the side door connecting plate 13 is connected to the guide rail 26 through the guide rail mounting plate 20. The slider 25 is fixedly connected to the slider mounting plate 24 directly connected to the frame of the refrigeration warehouse 1, and the slider mounting plate 24 is locked on the slider mounting fixing plate 23.

[0034] Finally, place the torsion spring 16 in the notch in the middle of the shaft seat 15, and install the two pins of the torsion spring 16 into the corresponding empty positions, then place the reagent bottle seat 2 on the shaft seat 15, and then pass the second rotating shaft 17 through the center hole of the reagent bottle seat 2, the shaft seat 15 and the torsion spring 16, and determine the relative position of the second rotating shaft 17 relative to the shaft seat 15 by tightening the screws, then connect the side door 14 to the side door connecting plate 13, and then install the shaft seat 15 on the side door connecting plate 1 3, and then install the door flip trigger slope 21 on the slope mounting plate 22, and the slope mounting plate 22 is installed on the air duct on the refrigeration warehouse 1, and finally the door rotation lever 18 is installed at one end of the second rotating shaft 17, and then locked by the nut 19, and the bearing retaining ring 27 and the bearing 4 are locked on the door rotation lever 18 by countersunk screws, and a limiting groove is set on the slope, and the limiting groove is used to prevent the reagent bottle holder 2 from automatically flipping and resetting under the action of the torsion spring 16.

[0035] When using a mechanism of the present embodiment that can realize the opening, closing and flipping of the side door 14 of the refrigeration module, the reagent bottle seat 2 is a reagent bottle tray, and the reagent bottle seat 2 is placed on the inner side of the side door 14. The reagent bottle A28 and the reagent bottle B29 are placed in the reagent bottle seat 2. The side door 14 can be pulled out of the refrigeration warehouse 1 or put into the refrigeration warehouse 1. The side door 14 can be pulled out by translation through the linear guide slider assembly, so that the pulling and pushing operation of the reagent bottle seat 2 of the refrigeration module can be realized. Through the coordinated use of the inclined plane mechanism and the torsion spring 16, the flipping movement of the reagent bottle seat 2 based on the translation of the linear guide slider assembly can be realized. The damping of the pulling and pushing action of the reagent bottle seat 2 can be adjusted by the synchronous belt drive assembly, so that the operator's operating feel can be adjusted.

[0036] The main design point of the utility model is to realize the pull-out and flipping action, so the refrigeration part will not be described.

[0037] The present invention mainly describes the manual operation process, and no detailed description is given for the motor drive. When the motor drive is required, the drive motor is directly connected to the synchronous belt transmission assembly and appropriate control is added.

[0038] When the reagent bottle A28 and the reagent bottle B29 need to be replaced, the operator can directly hold the side door 14 and pull it outward. Due to the action of the synchronous belt transmission assembly, there will be resistance during the pulling process, thereby ensuring that the pulling action is smooth and the side door 14 can stop at any position.

[0039] The assembly process of the synchronous belt transmission assembly is as follows: the synchronous belt adjusting screw 8 is directly clamped in the U-shaped groove on the pulley shaft seat mounting plate 30, and it is screwed into the adjustable pulley bearing seat 6. The adjustable pulley bearing seat 6 is fixed to the pulley shaft seat mounting plate 30 by screw locking. The locking screw is loosened. The tightness of the synchronous belt 10 can be adjusted by the synchronous belt adjusting screw 8. When assembling the synchronous pulley 7, one of the bearings 4 is preferentially installed in the adjustable pulley bearing seat 6 and the pulley shaft seat 12, and then the first rotating shaft 5 is passed through the circular hole of the synchronous pulley 7 along the hole, and the shaft end of the rotating shaft is installed in the bearing 4, and then another bearing 4 is installed in the other end of the first rotating shaft 5. Finally, the bearing baffle plate 3 is clamped in the slot on the first rotating shaft 5 to prevent the bearing 4 from falling off. The pulley shaft seat mounting plate 30 is directly connected to the frame of the refrigeration warehouse 1 with screw locking (not shown in the figure) to facilitate modular installation and maintenance of the synchronous belt transmission assembly.

[0040] In view of the different experience requirements of different operators, the tightness of the synchronous belt 10 can be adjusted by the synchronous belt adjusting screw 8. If it is necessary to change the manual operation to motor control, the driving motor can be connected to the synchronous pulley 7 away from the synchronous belt adjusting screw 8. The adjustable pulley bearing seat 6 and the pulley shaft seat 12 are installed on the pulley shaft seat mounting plate 30, and a guide structure for moving along the linear guide slider assembly is designed between the adjustable pulley bearing seat 6 and the pulley shaft seat mounting plate 30 to facilitate the adjustment of the linear guide slider assembly. For the synchronous belt connecting plate 9, the structural design needs to ensure that it can pass through the synchronous pulley 7 and the adjustable pulley bearing seat 6 smoothly.

[0041] The utility model adopts the linear guide rail 26 assembly, the inclined plane mechanism and the torsion spring 16 to realize the function of the reagent bottle turning over and automatically resetting along with the reagent bottle holder.

[0042] When the operator pulls the side door 14 outward, the side door connecting plate 13 directly connected to the side door 14 is connected to the guide rail 26 through the guide rail mounting plate 20, and the slider 25 is fixedly connected to the slider mounting plate 24 directly connected to the frame of the refrigeration warehouse 1. When the side door 14 is pulled outward, the linear guide rail 26 will make a linear motion relative to the slider 25; when the bearing 4 installed on the warehouse door rotating lever 18 contacts the warehouse door flip trigger inclined surface 21, the second rotating shaft 17 fixedly connected to the warehouse door rotating lever 18 will rotate accordingly, thereby driving the reagent bottle locked on the second rotating shaft 17 with a set screw The seat 2 rotates, and the height of the inclined surface can be accurately calculated according to the required rotation angle. When the operator pulls the side door 14 into place, the bearing 4 moves into the limiting groove designed on the door flip trigger inclined surface 21, which can prevent the reagent bottle seat 2 from automatically flipping and resetting under the action of the torsion spring 16; after replacing the reagent bottle, the operator pushes the side door 14 back with an appropriate thrust. At this time, under the action of a certain thrust, the bearing 4 will pass over the limiting groove designed on the door flip trigger inclined surface 21, and as the bearing 4 slowly loses contact with the door flip trigger inclined surface 21, the reagent bottle seat 2 is reset to a closed state under the action of the torsion spring 16.

[0043] The installation and connection method of the linear guide rail 26 assembly, the inclined plane mechanism and the torsion spring 16 is as follows: first, place the torsion spring 16 in the notch in the middle of the shaft seat 15, and install the two pins of the torsion spring 16 into the corresponding empty positions, then place the reagent bottle seat 2 on the shaft seat 15, then pass the second rotating shaft 17 through the center hole of the reagent bottle seat 2, the shaft seat 15 and the torsion spring 16, and determine the relative position of the second rotating shaft 17 relative to the shaft seat 15 by tightening screws, then connect the side door 14 to the side door connecting plate 13 by screws, and then install the shaft seat 15 on the side door connecting plate 13, connect the slider mounting plate 24 to the slider 25 with screws, and then install the guide rail 26 on the guide rail mounting plate 20, and finally install the guide rail mounting plate 20 is connected and locked with the side door connecting plate 13 by screws. At the same time, it is also necessary to lock the slider mounting plate 24 on the slider mounting fixing plate 23 (the slider mounting fixing plate 23 is directly installed and locked on the air duct on the refrigeration warehouse 1 with screws), and then the warehouse door flip trigger slope 21 is connected to the slope mounting plate 22 with screws, and the slope mounting plate 22 is also installed and locked on the air duct on the refrigeration warehouse 1 by screws. Finally, the warehouse door rotation lever 18 is installed at one end of the second rotating shaft 17, and then locked by the nut 19-19 (after locking, the locking screw for locking the second rotating shaft 17 can be loosened, and the warehouse door rotation lever 18 is adjusted to a suitable position and then the locking screw is locked), and the bearing retaining ring 27 and the bearing 4 are locked on the warehouse door rotation lever 18 by countersunk screws.

[0044] The translation and flipping actions in the utility model are realized by a new mechanism evolved from the classic crank slider 25 mechanism. For the inclined plane mechanism, there are two active components, namely the slider 25 and the connecting rod. There are two low pairs and one high pair in the mechanism, namely the high pair formed by the moving pair, the rotating pair, and the guide wheel and the frame line surface contact. According to the calculation method of the degree of freedom in the mechanical principle, the degree of freedom of the mechanism can be calculated as f=3*N-2*nm, where N represents the number of active components, n represents the number of low pairs, and m represents the number of high pairs. The degree of freedom f=1 is finally obtained by substituting the data, indicating that this mechanism only needs one drive to operate.

[0045] As for the inclined plane profile in the inclined plane mechanism, it needs to be designed in detail according to the use requirements in actual design and manufacturing to obtain ideal motion performance. This utility model does not design the inclined plane profile in detail, but only provides a solution. In the actual design process, the inclined plane profile can be determined according to the displacement s of the slider 25 and the rotation angle θ of the connecting rod.

[0046] In summary, the utility model can adjust the damping of the pulling and pushing action of the reagent bottle holder by setting the synchronous belt drive assembly, thereby realizing the adjustable operation feel of the operator, and by setting the linear guide slider assembly and the crank slider assembly, when replacing the reagent in the reagent bottle in the refrigeration module, the reagent bottle holder can be pulled out for a suitable distance and then flipped, which can be more convenient for the operator to take the reagent bottle when replacing the reagent in the reagent bottle, and solves the technical problems of difficulty in replacing the reagent bottle in the refrigeration module of the existing blood cell analysis and specific protein analysis all-in-one machine, the reagent bottle in the refrigeration module is not smooth to pull the reagent bottle holder, and the resistance cannot be adjusted.

[0047] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
