The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The embodiment provides a device for conveniently loading reagent cards, as shown in fig. 1-2, comprising:
a bottom plate group 100;
a tray set 200 installed on the bottom plate set 100, wherein a reagent card set 500 can be placed on the tray set 200;
guide optical axes 102 fixed to both sides of the bottom plate group 100;
a pressing plate group 400 having a through hole capable of being matched with the guide optical axis 102, wherein the pressing plate group 400 is mounted on the guide optical axis 102 through the through hole, and the pressing plate group 400 is capable of moving along the guide optical axis 102; when the pressing plate set 400 is close to the bottom plate set 100, the reagent card set 500 can be clamped and fixed;
a pressing plate group lifting mechanism 300 for lifting the pressing plate group 400, wherein the pressing plate group lifting mechanism is provided with a self-locking mechanism for locking the height after the pressing plate group 400 is lifted to a certain height;
a platen set pull-down mechanism for applying a force to platen set 400 toward bottom plate set 100.
The device for conveniently loading the reagent card of the embodiment has the use method that:
s1, using the platen set elevating mechanism 300 to elevate the platen set 400 such that the platen set 400 is at a height from the bottom plate set 100 sufficient to accommodate the reagent card set 500, as shown in fig. 4, and then positioning with a self-locking mechanism;
s2, placing the reagent card set 500 on the tray set 200 as shown in fig. 4;
s3, as shown in fig. 5, the self-locking mechanism cancels self-locking, and the pressing plate set 400 is driven by the pressing plate set pull-down mechanism to approach the bottom plate set 100, so as to clamp and fix the reagent card set 500.
Preferably, in the device for conveniently loading reagent cards of the present embodiment, as shown in fig. 3, the platen group elevating mechanism includes:
a pedestal bearing 302 fixed to the bottom plate assembly 100;
a transmission shaft 301 mounted on the pedestal bearing 302;
a first link 304;
a second link 305;
one end of the first connecting rod 304 is fixed to the transmission shaft 301, the other end of the first connecting rod is hinged to one end of the second connecting rod 305, and the other end of the second connecting rod 305 is rotatably connected to one side of the pressing plate group 400;
the self-locking mechanism is a protrusion 404 protruding from one side of the pressure plate set 400, the protrusion 404 is located on one side of the hinge joint of the second connecting rod 305 and the pressure plate set 400, an edge of the protrusion 404 has an inclined surface 4041, and the edge of the second connecting rod 305 is restricted from rotating when abutting against the inclined surface 4041. The principle of the lifting mechanism is as follows: when the first link 304 rotates to drive the second link 305 to rotate, the projection heights of the first link 304 and the second link 305 in the vertical direction (i.e., the height from the platen set 400 to the bottom plate set 100) change, that is, the heights of the platen set 400 change along with the rotation of the first link 304. As shown in fig. 4, when the platen group 400 is raised to the maximum (the first link 304 and the second link 305 form an angle of 180 degrees), the operator rotates the first link 304 counterclockwise by a certain angle, so that the included angle between the first link 304 and the second link 305 is smaller than 180 degrees, and at this time, the left side of the second link 305 is blocked by the inclined surface 4041 and is restricted from rotating, so when the operator removes the external force, the platen group pull-down mechanism gives a force to the platen group 400 toward the bottom plate group 100, at this time, there is a downward pulling force on the upper end of the second link 305, there is an upward pulling force on the lower end of the first link 304, that is, the platen group pull-down mechanism gives a tendency that the second link 305 rotates clockwise, but due to the restriction of the inclined surface 4041, the second link 305 cannot rotate clockwise, so that the first link 304 and the second link 305 as a whole cannot rotate under the force of the platen group pull-down mechanism, forming a 'self-locking' state. The principle of releasing the self-locking state of the lifting mechanism is as follows: as shown in fig. 3-5, the protrusion 404 is located on the left side of the hinge of the second link 305 and the pressure plate set 400, so that the operator only needs to rotate the first link 304 clockwise, and when the second link 305 rotates counterclockwise, the right side of the second link 305 is not restricted, as shown in fig. 5, the pressure plate set 400 tends to move downward (the tendency of clamping the reagent card set 500) under the driving of the pressure plate set pulling-down mechanism.
Preferably, in the device for conveniently loading reagent cards of the present embodiment, as shown in fig. 3, the transmission shaft 301 is connected with a rotating handle 303 or a driving machine. An operator may manually rotate drive shaft 301 by rotating handle 303.
