[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] As attached Figure 1-3 As shown, the utility model discloses a blood analyzer, comprising a box body 1, a box cover 2 for buckling with the box body 1, an analyzer body 3 placed in the box body 1, and a scissor arm and a curtain arranged between the box body 1 and the box cover 2.

[0023] The curtain includes side curtains 6 located on the left and right sides between the box body 1 and the box cover 2 and a rear curtain 13 located at the rear side thereof. A rotating shaft A11 with a torsion spring is respectively arranged on the left and right sides inside the box body 1. The lower end of the side curtain 6 is wound around the rotating shaft A11, and the upper end is fixedly connected to the top of the box cover 2. A rotating shaft B12 with a torsion spring is arranged at the rear side of the box cover 2. The upper end of the rear curtain 13 is wound around the rotating shaft B12, and the lower end is fixedly connected to the rear side wall inside the box body 1. During the separation process of the box body 1 and the box cover 2, the rotating shaft A11 and the rotating shaft B12 rotate, and the side curtains and the rear curtains are pulled out on the corresponding rotating shafts, and the three sides of the space between the box body 1 and the box cover 2 are all blocked, leaving only the front side for easy detection operation, which can minimize the pollution of the environment to the detection process and the instrument. At the same time, due to the effect of the torsion spring, the curtain can always be kept in a tensioned state. During the buckling process of the box body 1 and the box cover 2, under the action of the torsion spring, the curtain can be wound around the corresponding rotating shaft to achieve storage.

[0024] There are two groups of scissor arms, which are respectively located on the left and right sides of the box body 1, including a mounting plate A7 fixedly arranged on the inner side of the side wall of the box body 1, a mounting plate B9 fixedly arranged on the inner side of the side wall of the box cover 2, a slide groove A8 arranged on the mounting plate A7, a slide groove B10 arranged on the mounting plate B9, a fork arm A19 with one end arranged on the mounting plate A7 through a rotating shaft and the other end slidingly connected to the slide groove B10, and a fork arm B20 with one end slidingly connected to the slide groove A8 and the other end rotationally connected to the mounting plate B9 through a rotating shaft. The fork arm A19 and the fork arm B20 are arranged crosswise in an X shape, and a rotating shaft is arranged at the intersection of the X shape.

[0025] Pulleys 18 are installed at the movable ends of the fork arm A19 and the fork arm B20, and the pulleys 18 are installed in the corresponding slide grooves A8 and B10.

[0026] As an embodiment of the utility model, a detachable support rod is provided between the box body 1 and the box cover 2. When the box cover 2 is opened upward, the support rod is installed to keep the box cover 2 in a high position (i.e., the box body 1 is opened). After that, the box can be used normally. The structure of supporting two objects by using the support rod is common knowledge to those skilled in the art and will not be described here.

[0027] As another embodiment, the utility model also discloses a locking pin mechanism, which can lock the box cover 2 to maintain the high position when it is lifted to the highest position. The locking pin mechanism includes through holes on the left and right side walls of the box cover 2, a locking pin 15 disposed in the through holes, and a matching hole 14 disposed on the central rotating shaft of the pulley at the top of the fork arm A19. When the box cover 2 is lifted to the highest position, the matching hole 14 corresponds to the through hole on the side wall of the box cover 2, and the locking pin 15 is inserted into the matching hole 14, so that the top of the fork arm A19 can be locked, so that the scissor arms cannot move, and the box cover 2 can be maintained in the highest position.

[0028] Preferably, a spring 16 for keeping the lock pin 15 in a locked state is provided between the lock pin 15 and the side wall of the box cover 2, and an end cover 17 is provided at the outer end of the lock pin 15. The spring 16 is a tension spring and is sleeved on the lock pin 15, one end of which is fixedly connected to the side wall of the box cover 2, and the other end is fixedly connected to the end cover 17. The tension of the spring is used to keep the lock pin 15 in a locked state at all times. When it is necessary to adjust and close the box cover 2, the lock pin 15 is pulled outward to disengage it from the matching hole 14, and the scissor arms can return to the moving state. There are two lock pins 15, which are respectively arranged on the left and right sides of the box cover 2. The two lock pins 15 need to be pulled outward at the same time to unlock the two scissor arms, which can also avoid accidental closure of the box cover 2 due to misoperation.

[0029] As a further improvement of this embodiment, the inner end face of the locking pin 15 is a slope, and the slope faces the front side of the box cover 2. The advantage of this structure is that during the upward movement of the box cover 2, the top pulley of the fork arm A19 moves toward the locking pin 15. The slope can play a transition role and can automatically push the locking pin 15 outward. The pulley continues to move until the matching hole 14 corresponds to the position of the locking pin 15. Under the pulling force of the spring 16, the locking pin 15 cooperates with the matching hole 14 to achieve automatic locking, which is more convenient to use.

[0030] In order to facilitate the internal space layout, the mounting plate A7 is located on the outside of the corresponding rotation axis A11, and the rotation axis B12 is located on the upper side of the mounting plate B9.

[0031] As a further improvement of the present invention, a sealing strip is provided at the connection position between the box body 1 and the box cover 2, and a filling block for filling the gap between the inner wall of the box body 1 and the analyzer body 3 is provided to prevent the analyzer body 3 from shaking.

[0032] The box body 1 and the box cover 2 of the utility model adopt a separate structure, and a scissor arm is used to support the two in a separated state. Curtains are correspondingly arranged on the three sides between the box body 1 and the box cover 2. When in use, the box cover 2 is in a high position, and the curtains are opened as the box cover 2 moves upward, which can achieve a better protective effect. At the same time, the front side is left empty, which is convenient for detection operations.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
