In this embodiment, as shown in fig. 8 and 9, the reagent card 50 may have an approximately rectangular parallelepiped structure, wherein a groove 51 may be formed on a side of the reagent card 50, and a positioning groove 52 may be formed on a back of the reagent card 50; of course, the shape and structure of the reagent card 50 are not limited to the above description, and other suitable deformation structures can be applied, and are not particularly limited herein. Of course, in other embodiments, the card-inserting device 10 can also be used for fixing other cards, and is not limited herein.
The invention provides a card-insertion device 10, as shown in fig. 2 to 9, the card-insertion device 10 comprises a body 1, a pushing member 2 and a driving device 3.
The body 1 is provided with a first slot 11 for inserting a clamping piece; it should be noted that, in the present embodiment, a card member, such as a reagent card 50, is inserted into the first slot 11, wherein the reagent card 50 may be a single card, a double card, a triple card or other multiple cards, the width of the first slot 11 is wider than the width of the card member, such as the reagent card 50, so as to support the reagent card 50 to be inserted into the first slot 11 at will, wherein the reagent card 50 is approximately rectangular parallelepiped, that is, the width of the first slot 11 corresponds to the shorter end of the reagent card 50, and the length of the first slot 11 corresponds to the longer end of the reagent card 50.
The output end of the driving device 3 is connected with the pushing piece 2, the driving device 3 drives the pushing piece 2 to movably extend into the first slot 11 or extend out of the first slot 11 along the width direction of the first slot 11, and the pushing piece 2 abuts against the clamping piece when extending into the first slot 11. It should be noted that, as shown in fig. 7, the front end of the main body 1 near the operator has a slot entrance 111 for facilitating the insertion of the card into the first slot 11 from the slot entrance 111, the right side of the main body 1 has a channel communicating with the first slot 11, and the bottom of the main body 1 corresponding to the first slot 11 has a positioning slot 52 and the like. It can be understood that the driving device 3 drives the pushing member 2 to move in the first slot 11 along the width direction of the first slot 11, so that the pushing member 2 can adaptively adjust the position of the pushing member 2 in the first slot 11 according to the width of the card inserted into the first slot 11, so that the slot wall of the first slot 11 on the side far from the pushing member 2 and the pushing member 2 together clamp the card to make the card be stably fixed in the first slot 11. Specifically, in this embodiment, the pushing element 2 and the driving device 3 are integrated on the body 1, so as to improve the structural compactness of the card insertion device 10, wherein the channel of the body 1 corresponding to the first slot 11 is provided with the channel extending along the width direction of the first slot 11 and communicated with the first slot 11, and the pushing element 2 movably extends into the first slot 11 or extends out of the first slot 11 along the channel.
It will be appreciated that the principle of operation of the cardholder 10 is substantially as follows: inserting the card member into the first slot 11 of the body 1; according to the position of the clamping piece in the first slot 11, the driving device 3 is controlled to drive the pushing piece 2 to extend into the first slot 11 along the width direction of the first slot 11 to abut against the clamping piece, so that the clamping piece is clamped by the slot wall of the first slot 11 far away from one side of the pushing piece 2 and the pushing piece 2 together to enable the clamping piece to be stably fixed in the first slot 11. When the clamping piece needs to be taken out, the driving device 3 reversely drives the pushing piece 2 to extend out of the first slot 11 along the width direction of the first slot 11 so as to be separated from the clamping piece, and at the moment, the clamping piece is separated from the clamping state and can be taken out quickly.
In summary, the card insertion device 10 drives the pushing element 2 to movably extend into the first slot 11 or extend out of the first slot 11 along the width direction of the first slot 11 through the driving device 3, so as to adjust the position of the pushing element 2 in the first slot 11 according to the width of the card element inserted into the first slot 11, such as the reagent card 50, so that the slot wall of the first slot 11 on the side away from the pushing element 2 and the pushing element 2 clamp the reagent card 50 together, so that the reagent card 50 is stably fixed in the first slot 11. Therefore, the first slot 11 of the card inserting device 10 can be adapted to the reagent cards 50 with different widths, the reagent cards 50 can be inserted into the first slot 11 at will and positioned and stably clamped without being accurately inserted into the first slot 11, brackets with different types are not required to be equipped for stably clamping the reagent cards 50, the multiple cards can be simultaneously clamped and taken, and the card inserting device has the characteristics of simple structure and simplicity and convenience in operation.
In some embodiments, as shown in fig. 4 to 9, the pushing member 2 is provided with a first mating member for mating with a second mating member of the card, and when the pushing member 2 movably extends into the first slot 11 along the width direction of the first slot 11, the pushing member 2 can mate with the second mating member of the card through the first mating member to adjust the position of the card inserted into the first slot 11. It can be understood that, when the card member, such as the reagent card 50, is inserted into the first slot 11 at will and is not located at an accurate position relative to the first slot 11, for example, when the card member is disposed obliquely, and the pushing member 2 is driven by the driving device 3 to extend into the first slot 11, the reagent card 50 can be driven by the pushing member 2 to smoothly adjust its position through the cooperation of the first fitting member and the second fitting member, so that the reagent card 50 is accurately inserted into the first slot 11, thereby effectively preventing the reagent card 50 from shifting relative to the first slot 11 and affecting subsequent detection operations. Therefore, through the second fitting piece cooperation that sets up first fitting piece and fastener at impeller 2 to make this first slot 11 adapt to the reagent card 50 of different width under impeller 2's effect, can adjust the position of reagent card 50 so that reagent card 50 is fixed to be installed in first slot 11 accurately simultaneously, the user can insert reagent card 50 at will, further improves user experience and feels, improves the convenient and fast nature of plug-in card.

It can be understood that the triangular protrusion 21 and the triangular groove 51 are in inclined contact through the cooperation of two inclined surfaces, so that on one hand, the contact area between the protrusion 21 and the groove 51 can be increased, and on the other hand, the inclined surfaces can guide the movement between the reagent card 50 and the pushing member 2, so that the reagent card 50 can slide to the final matching point of the protrusion 21 and the groove 51 under the action of the inclined surfaces, and thus the offset position of the reagent card 50 can be effectively adjusted. Of course, in other embodiments, the protrusion 21 and the groove 51 may have other suitable shapes, such as a trapezoid, etc., and are not limited herein.

In some embodiments, the driving device 3 may be a screw transmission motor, and the screw transmission motor can drive the pushing member 2 to move linearly along the width extending direction of the first slot 11, and has the characteristics of high precision, high efficiency, and small friction force. Of course, in other embodiments, the driving device 3 may be a linear motor, and the like, and is not particularly limited herein.
In some embodiments, as shown in fig. 3, the body 1 and the pusher 2 are connected by a buffer 5 at a position between the driving device 3 and the pusher 2.
