In addition, because the sample frame 2 drives the automatic door 3 to be opened or closed through the transmission device 4, the direct connection between the automatic door 3 and the sample frame 2 is avoided, the interference of the door opening and closing action on the in-and-out action of the sample frame 2 is reduced, the accurate positioning of the sample frame 2 is facilitated, and the accuracy of a sample analysis result is improved.

Optionally, the driving device 10 may be a motor, the power output end of the driving device 10 is provided with a gear 100, the sample rack 2 is provided with a rack 22 meshed with the gear 100, the sample rack 2 is moved along the box 1 through a rack-and-pinion, the sample rack has a long service life and a constant transmission ratio, the sample rack 2 can be accurately stopped at a set position, smooth sample analysis is facilitated, and the rack-and-pinion works stably and reliably, so that the sample rack 2 can be ensured to slide along the box 1 smoothly, and the sample rack 2 is prevented from generating great shaking to cause risks such as sample scattering. Of course, any device capable of generating linear motion, such as a hydraulic device, may be used as the driving device 10.

Specifically, a base 19 may be disposed in the box 1, and the extending direction of the base 19 is the same as the moving direction of the sample rack 2. The driving device 10 can be fixedly connected to the base 19, so that the driving device 10 and the box body 1 are kept relatively static, and the driving device 10 is prevented from generating vibration to influence the accuracy of an analysis result or generate larger noise in the using process of the device; the base 19 may be provided with guides along which the sample holders 2 slide, ensuring that the sample holders 2 move in a predetermined direction. The housing 1 should also be provided with a control center by means of which the movements of the relevant components (e.g. the drive means 10 or the analysis instrument, etc.) inside the housing 1 are controlled.

Further, the transmission device 4 is a crank-link mechanism, the crank-link mechanism comprises a sliding block 40, a connecting rod 42 and a crank 44 which are sequentially connected, the sliding block 40 slides along the box body 1, the connecting rod 42 drives the crank 44 to rotate, the linear movement of the sample frame 2 is converted into the pivoting movement of the automatic door 3 through the crank-link mechanism, the structure is simple, the processing is convenient, two components forming the movement are in surface contact, the bearing pressure is small, the lubrication is convenient, the abrasion is light, and the large load can be borne. Of course, other mechanisms capable of converting linear motion into pivotal motion, such as rack and pinion mechanisms or lead screw and nut mechanisms, may be used for the transmission 4.

Preferably, the slider 40 is intermittently attached to the sample rack 2 and slides as the sample rack 2 slides along the case 1, for example, the slider 40 may be attached to the sample rack 2 by an intermittent motion mechanism (e.g., a ratchet mechanism, a geneva gear mechanism, a link mechanism, an incomplete gear mechanism, etc.); the intermittent sliding of the slide block 40 is converted into intermittent rotation of the crank 44 through the connecting rod 42; the crank 44 is fixedly connected to a side of the automatic door 3 facing the inside of the box, for example, the crank 44 may be integrally formed with the automatic door 3, or the crank 44 is fixed to the automatic door 3 by a fastening member or the like, so that the automatic door 3 intermittently rotates around a pivot shaft of the automatic door 3 along with the crank 44, thereby controlling the action time and the opening angle of the automatic door 3 and preventing the automatic door 3 from being opened by an excessively large angle. Specifically, when the slide block 40 is connected with the sample rack 2, the slide block 40 slides along the box body 1 along with the sample rack 2, and the crank 44 starts to rotate to realize the door opening and closing action; when the slide block 40 is disengaged from the sample rack 2, the sample rack 2 slides along the box body 1 alone, the slide block 40 is kept stationary, and the crank 44 stops rotating to keep the automatic door 3 stationary.

Furthermore, a stop 20 is convexly arranged on one side of the sample rack 2 facing the slide block 40, the stop 20 can abut against the slide block 40 or release the slide block 40, and the stop 20 abuts against one side of the slide block 40 facing the opening 12. When the stop block 20 is abutted against the slide block 40, the slide block 40 slides along the box body 1 along with the sample rack 2 to realize the door opening and closing action; when the stop 20 releases the slide 40, the sample rack 2 alone slides along the case 1, the slide 40 remains stationary and the automatic door 3 remains stationary.

Specifically, the sample rack 2 of the medical sample analyzer provided in the embodiment of the present application moves in and out and opens and closes the door as follows:

when the sample rack 2 needs to be taken out of the box body 1, the sample rack 2 moves towards the direction of moving out of the box body 1, the sliding block 40 moves towards the direction close to the opening 12 along with the stop block 20, the automatic door 3 is gradually opened (see fig. 3), and the stop block 20 controls the moving speed of the sliding block 40, so that the automatic door 3 is slowly opened; when the automatic door 3 is opened to the maximum angle, the slider 40 is kept stationary as the automatic door 3 stops moving, the stopper 20 releases the slider 40 to slide alone, and the sample rack 2 continues to move to the takeout position along the opening of the automatic door 3 (see fig. 4). When the sample rack 2 needs to be fed into the box body 1, the sample rack 2 moves in the direction of moving into the box body 1, and the automatic door 3 remains still (see fig. 4); the sample rack 2 gradually moves to the inner side (the side facing the inside of the box body 1) of the automatic door 3 along the opening of the automatic door 3, at this time, the stopper 20 abuts against the slide block 40, the slide block 40 starts to move along with the stopper 20, and the automatic door 3 starts to be closed (see fig. 3); until the automatic door 3 is completely closed, the sample rack 2 stops moving simultaneously with the automatic door 3 (see fig. 2).

Further, the box body 1 is provided with a slide rail 14 adapted to the slide block 40, the slide block 40 slides along the slide rail 14, one end of the slide rail 14 close to the stopper 20 is provided with a limiting member 140, the limiting member 140 can be fixed to the slide rail 14 through a fastening member 144 (e.g., a screw), and abuts against the slide block 40 through the limiting member 140, so as to limit the movement of the slide block 40, and separate the slide block 40 from the stopper 20, that is, the driving member of the transmission device 4 is limited to stop the transmission device 4 from moving, thereby preventing the stress condition of the automatic door 3 from changing during the opening process, and further enabling the automatic door 3 to stop at the maximum opening angle position more stably. Of course, it is also possible to stop the movement of the transmission 4 by limiting the intermediate transmission member (connecting rod 42) or the driven member (crank 44 or automatic door 3) of the transmission 4.

Further, the elastic member 142 is disposed on a side of the limiting member 140 away from the sliding block 40, and the elastic member 142 forms a buffer, so that the sliding block 40 can stop moving smoothly, and the automatic door 3 is prevented from vibrating due to violent impact between the sliding block 40 and the limiting member 140.

Further, the medical sample analysis device that this application embodiment provided is equipped with electromagnetic lock 16 in one side of opening 12, is equipped with on the automatically-controlled door 3 with electromagnetic lock 16 matched with lockhole 440, when automatically-controlled door 3 closed completely, electromagnetic lock 16 inserts lockhole 440 to locking automatically-controlled door 3, stability when increasing automatically-controlled door 3 and closing prevents that sample analysis in-process automatically-controlled door 3 from rocking. The electromagnetic lock 16 is energized simultaneously with the driving device 10, that is, when the sample rack 2 starts to move when the driving device 10 is energized, the electromagnetic lock 16 is energized simultaneously to disengage from the lock hole 440 to release the automatic door, so that the automatic door 3 can be opened along with the movement of the sample rack 2.

Further, the electromagnetic lock 16 can automatically return, the automatic door 3 is further provided with a track groove 442, the track groove 442 is arranged on one side of the lock hole 440 and extends to the lock hole 440, when the electromagnetic lock 16 is separated from the lock hole 440, the electromagnetic lock 16 automatically pops out and slides along the track groove 442, when the sample rack 2 moves reversely, the electromagnetic lock 16 can reversely slide into the lock hole 440 along the track groove 442, the automatic door 3 is automatically locked, manual locking is not needed, and operation is more convenient.

Preferably, since the locking hole 440 and the crank 44 are both rotated about the pivot axis of the automatic door 3, the locking hole 440 and the track groove 442 may be directly disposed on the crank 44. On the one hand, the structure of the automatic door 3 can be simplified; on the other hand, the crank 44 is formed in a shape of an approximately arc-shaped structure, so that the crank 44 has a large area, thereby increasing the rigidity of the crank 44 and preventing the crank 44 from being damaged by breakage, deformation, or the like.

Further, an energy storage device 5 (e.g., a torsion spring, etc.) is disposed between the pivoting shaft of the automatic door 3 and the case 1, and the energy storage device 5 is connected to the pivoting shaft of the automatic door 3. When the automatic door 3 is closed, the energy storage device 5 stores energy, so that the closing speed of the automatic door 3 is slowed down, and the automatic door 3 is prevented from vibrating or impacting the box body 1; when the automatic door 3 is opened, the energy storage device 5 releases energy to ensure that the automatic door 3 can be smoothly opened.

Furthermore, the box 1 may be further provided with a position sensor 18, an input end of the position sensor 18 is connected to the automatic door 3, an output end of the position sensor 18 is connected to the driving device 10, and an output end of the position sensor 18 may be directly connected to the driving device 10 or indirectly connected (for example, connected through a control center). The position of the automatic door 3 can be detected by the position sensor 10, ensuring that the automatic door 3 can be completely closed, and ensuring that the parking position of the sample rack 2 in the box body 1 and the position where the automatic door 3 is closed remain unchanged. That is, when the position sensor 18 detects that the automatic door 3 reaches the fully closed position, the driving device 10 stops the operation in response to the signal, and the sample rack 2 stops moving and the automatic door 3 stops rotating.

Preferably, the position sensor 10 is a photoelectric position sensor, which includes a light source and a light receiver disposed opposite to each other; be equipped with light screen 30 on automatically-controlled door 3, light screen 30 can rotate to between light source and the light receiver along with automatically-controlled door 3, need not to make automatically-controlled door 3 and position sensor 3 contact, improves the accuracy of response, and can make position sensor 3 remain stable performance in the longer time.

Specifically, the side of the automatic door 3 facing the inside of the box 1 may be convexly provided with an extension portion 32, and the extension portion 32 and the crank 44 are in a symmetrical structure along the width direction of the automatic door 3, so that the whole automatic door 3 is kept balanced. Since each actuating component is located at the side of the crank 44, and there is no obvious actuating component at the side of the extending portion 32, the light shielding plate 30 can be connected to the front end (the end far away from the automatic door 3) of the extending portion 32, so as to reduce the interference of other actuating components to the position sensor 3 and improve the accuracy of the position sensor 3.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
