[0040] In order to more conveniently explain the adjustment device provided in the embodiment of the present application, the technical solution of the present application will be explained in detail below as an example rather than a limitation.

[0041] The regulating device provided by the present application is now described in detail with reference to the accompanying drawings.

[0042] Example 1

[0043] See also Figure 1-4 An adjusting device comprises a first fixing plate, a first connecting member and a first fixing block, wherein the first fixing plate is used to be fixedly connected to the door, the first connecting member is used to connect the first fixing plate and the first fixing block, and the first fixing block is used to connect the base.

[0044] The first fixing plate is connected to the door by bolts. Specifically, the first fixing plate includes a hinge fixing plate 101 and a rotating shaft connecting plate 102, wherein the hinge fixing plate and the rotating shaft connecting plate are designed as one piece, and the hinge fixing plate and the rotating shaft connecting plate are vertically connected. More specifically, the hinge fixing plate is provided with a first through hole 103, and the bolt passes through the first through hole to connect the first fixing plate to the door; the rotating shaft connecting plate is provided with a second through hole, and the bolt passes through the second through hole to fix the first fixing plate to the right rotating shaft.

[0045] The first connecting member includes a left rotating shaft 201, a right rotating shaft 202, and a tightening screw 203. The tightening screw is screwed into the right rotating shaft, and the rotating shaft passes through the tightening screw and is sleeved on the right rotating shaft.

[0046] In order to achieve the purpose of adjusting the tightness when the door is opened, the right shaft is provided with two slender symmetrically arranged slots 2021 along the length direction of the shaft. As the screwing depth of the tension screw increases, the right shaft is squeezed by the tension screw and expands accordingly. Since the left shaft is sleeved on the right shaft, the matching clearance between the right shaft and the left shaft is reduced, thereby achieving the purpose of adjustment. It should be emphasized that the tension screw 203 has a structure with a large head diameter and a small tail diameter. Specifically, when the tension screw is screwed into the right shaft, the first part to enter the right shaft is the tail, that is, in the early stage of the tension screw being screwed into the right shaft, the right shaft will not open, and only when it reaches a certain depth will the right shaft be squeezed and expand.

[0047] The first fixing block 3 is provided with a first groove, and a bolt passes through the left rotating shaft to connect the left rotating shaft to the first fixing block, and the other side of the first fixing block is fixedly connected to the base. It should be noted that the base here can be fixedly connected to the instrument body, that is, the base part and the instrument body always remain in a relatively static state, and the hinge fixing plate moves relative to the instrument body, thereby driving the sample rack area door to open or close.

[0048] The right shaft 202 includes a first connecting portion and a second connecting portion of an integral design, wherein a second groove is provided in the first connecting portion, and a tensioning screw is screwed into the second groove of the first connecting portion, wherein a slender slot is provided on the second groove along the length direction of the right shaft, and as the tightening screw is screwed in deeper, the first connecting portion expands accordingly, and the matching clearance with the left shaft is reduced. The second connecting portion is fixedly connected to the shaft connecting plate.

[0049] like Figure 3 As shown, the tensioning screw 203 includes an integrally designed base 2031, a first expansion unit 2032, a first expansion unit 2033, a second expansion unit 2034, and a second expansion unit 2035. The right end of the base is conical, the left side of the base is the first expansion unit, the left side of the first expansion unit is the first expansion unit, the left side of the first expansion unit is the second expansion unit, and the left side of the second expansion unit is the second expansion unit. The first expansion unit and the second expansion unit are truncated cone structures, the first expansion unit and the second expansion unit are cylindrical structures, and the diameter of the second expansion unit is larger than that of the first expansion unit.

[0050] When the tension screw is screwed into the right shaft at the beginning, the right shaft will not expand due to the small base diameter, and the clearance between the left shaft and the right shaft is the smallest. When the tension screw is screwed in further, the first expansion unit enters the right shaft, and the right shaft expands slightly with the depth of the tension screw screwing in. When the second expansion unit enters the right shaft, the right shaft expands further. When the second expansion unit enters the right shaft, the expansion angle of the right shaft reaches the maximum, that is, the clearance between the left shaft and the right shaft is the smallest.

[0051] See also Figure 1 The left rotating shaft includes a third connecting part and a fourth connecting part of an integral design. The third connecting part is sleeved on the outer surface of the first connecting part, and the fourth connecting part is connected to the first fixing block by bolts.

[0052] The adjustment device of the present application can be widely used for flipping and opening small doors in in vitro diagnostic instruments. Through simple adjustment operations, the inspector can freely adjust the opening angle of the door as needed without having to hold the door with hands to prevent it from closing due to its own weight.

[0053] Specific applications:

[0054] Taking the sample rack door of an in vitro diagnostic instrument as an example, the device of the present application is used to connect the door and the instrument body. First, the shaft fixing block is fixed to the base, the base is connected to the sample rack compartment, and the left shaft is connected to the shaft fixing block by bolts. Then, the hinge fixing plate is fixed to the sample rack door, and the right shaft is connected to the hinge fixing plate by bolts. Finally, the tensioning screw is screwed into the right shaft, and the tightness of the door opening can be adjusted by adjusting the screw-in depth of the tensioning screw.

[0055] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Any non-substantial changes to the present application using this concept shall be deemed as an infringement of the protection scope of the present application.
