It is important to note that the door switching device of specific protein analyzer provided by the present invention should not be so limited
In such situation, fixed pulley mechanism 2 includes pulley bracket 22, joint pin 24 and fixed pulley 23, and fixed pulley 23 has guiding role,
For changing the direction of connecting rope 3.Pulley bracket 22 is mounted on frame plate 6, and joint pin 24 is mounted on pulley bracket 22, fixed
Pulley 23 is connect by joint pin 24 with pulley bracket 22, and structure is simple, facilitates installation fixed pulley 23.
The door switching device of specific protein analyzer provided by the present invention, in the immovable situation of other components,
Fixed pulley 23 have U-type groove, connecting rope 3 wind it is more convenient, prevent connecting rope 3 from fixed pulley 23 deviate from, it is safer.It is fixed sliding
Wheel 23 is identical as the height of door ontology 19, and the driving force for the connecting rope 3 that door ontology 19 is subject to is maximum, is easy to drive door sheet
Body 19.
For the door switching device of the specific protein analyzer in above-mentioned each embodiment, adaptive damping mobile pulley group
4 include pulley fixed frame 12, guiding axis 16, limited post 13, mobile pulley frame 10, spiral compression spring 11 and movable pulley 15, is slided
Wheel fixed frame 12 is fixed on frame plate 6, and guiding axis 16 and limited post 13 are fixed on 12 lower end of pulley fixed frame, mobile pulley frame
10 are set on guiding axis 16, and can move along guiding axis 16.The length for being shorter in length than guiding axis 16 of limited post 13, limited post
13 can limit the compression,metal-to-metal position of mobile pulley frame 10.Spiral compression spring 11 is set on guiding axis 16, and one end is solid
Due on pulley fixed frame 12, the other end is fixed on mobile pulley frame 10, for generating damping force.Movable pulley 15 passes through revolution
Pin shaft 9 is installed on mobile pulley frame 10, easy to connect around 9 rotation of fulcrum post axis when can slide with connecting rope 3, more reliably.
In order to further optimize the above technical scheme, movable pulley 15 has U-type groove, and connecting rope 3 winds more convenient, prevents
The abjection of 3 follow-up pulley 15 of connecting rope, it is safer.It is set with guide sleeve 14 in the through-hole of mobile pulley frame 10, there is guiding role,
Guide sleeve 14 is copper sheathing, is worn smaller.Mobile pulley frame 10 in hole mounted thereto by marking closely the fixed copper sheathing of screw by being existed
It is slided on guiding axis 16, specific guiding axis 16 is inserted in the hole of copper sheathing, and guiding axis 16 end, which can be set, prevents copper sheathing from skidding off
Step.
On the basis of above-mentioned each specific embodiment, adaptive damping mobile pulley group 4 passes through on pulley fixed frame 12
Two through-holes are screwed on frame plate 6, including at least two guiding axis 16, for example two 16 one end of guiding axis insertions are slided
In two holes for taking turns fixed frame 12, fixed with the screw of marking closely being mounted in 12 two sides of pulley fixed frame, between guiding axis 16
It is parallel to each other, is smoothly oriented to.
Another inventive concept provided by the present invention is, driving device include stepper motor 5, driving wheel, driven wheel,
Synchronous belt, the output axis connection of driving wheel and stepper motor 5, driven wheel are connect by synchronous belt with driving wheel, and reagent rack 7 is installed
It is connected in the reagent rack 7 on synchronous belt, moved along guide rail with the synchronous belt that stepper motor 5 drives, under the driving of stepper motor 5
It moves along the vertical direction.Connecting rope 3 is fixed in reagent rack 7 by pin 8.It is connect along the reagent rack 7 that guide rail moves with sliding block,
Pin 8 is mounted on sliding block, and reagent rack 7 is connect by pin 8 with connecting rope 3.
It is of the invention in actual use, reagent rack 7 is mounted on guide rail to be connect with synchronous belt unilateral side, mobile reagent
Frame 7 moves under the drive of synchronous belt along guide rail, and reagent cup is moved to bottom end test position from door ontology 19.Specifically may be used
Think that stepper motor 5 drives synchronous belt movement, spiral stretch when moving below guide rail due to being equipped on door guiding mechanism 1
20 initial tensile force of spring is greater than the damping of adaptive damping mobile pulley group 4, is mounted in adaptive damping mobile pulley group 4 and provides resistance
The spiral compression spring 11 of Buddhist nun's power starts to compress with the movement of mobile pulley 15, can variable resistance when the mobile certain displacement of reagent rack 7
The damping of Buddhist nun's pulley blocks 4 starts the pulling force for the spiral stretching spring 20 being greater than on door guiding mechanism 1, and door ontology 19 starts
It is pulled open under the action of connecting rope 3.
Make mobile pulley frame 10 and the movable pulley on adaptive damping running block by the connecting rope 3 connecting with reagent rack 7
15 move up along guiding axis 16, and the beginning of spiral compression spring 11 for providing damping force is compressed, and damping force is with pulley yoke
Displacement gradually increases.
The damping force produced by spiral compression spring 11 just greater than on door guiding mechanism 1 spiral stretching spring 20 it is pre-
When pulling force, mobile pulley frame 10 is contacted with limited post 13 just, and mobile pulley frame 10 is subsequent no longer to be moved, reagent rack 7 after
It is continuous to move up, draw door ontology 19 to move along the sliding slot of guide plate 17 by connecting rope 3, agent bin door body 19 is beaten automatically
It opens, spiral stretching spring 20 is drawn high with agent bin door body 19.
After agent bin door body 19 is opened, it is put into reagent cup, reagent rack 7 is moved down with reagent cup along guide rail, examination
Agent door ontology 19 is progressively closed off in the case where spiral draws high spring effect, and when drawing high, spring tension is mobile just greater than adaptive damping to be slided
When the elastic force of the spiral compression spring 11 in wheel group 4, agent bin door body 19 is closed just, and mobile pulley frame 10 is with reagent rack
7 constantly move down when moving down, and spiral compression spring 11 is gradually recovered, and agent bin door body 19 is completed to close.
The balance transition of 20 pulling force of spiral stretching spring is replied by adaptive damping mobile pulley group 4 and door ontology 19,
It completes the instrument bin door body 19 at guide rail bottom to close, the control that instrument bin door body 19 is opened in rail crown, entirely
For process without individual driving, movement is steady noiseless, controls and simply easily realizes.
In the description of the present invention, it should be noted that the orientation or positional relationship of the instructions such as upper and lower, bottom of term is
It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of description of the present invention and simplification of the description, rather than instruction or dark
Show that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as pair
