[0038] As Figure 4 、 Figure 6 、 Figure 8 shown, Figure 8 the left side in the figure is the front side of the battery compartment 1.1, Figure 8On the right side of the rear is the rear side of the battery compartment. One end of the battery door 3 is provided with a battery door buckle 3.3, and a buckle groove 1.1.5 corresponding to the position of the battery door buckle 3.3 is opened on the housing. The battery door buckle 3.3 and the buckle groove 1.1.5 cooperate to fix the battery door 3 and the battery compartment 1.1; the other end of the battery door 3 is provided with a door shaft 3.1. When the battery door buckle 3.3 is opened, the battery door 3 is hinged to the housing 1 through the door shaft 3.1; when the battery door 3 is closed, the door shaft 3.1 slides into the inner side of the housing 1; an inner side of the housing 1 is provided with a latch 1.1.10 extending towards the inner side of the housing 1, and the latch 1.1.10 is located on the path where the door shaft 3.1 slides into the inner side of the housing 1; the door shaft 3.1 includes a cylinder 3.1.1 and a "Ji"-shaped connecting member 3.1.2 for connecting the cylinder 3.1.1 and the battery door 3.

[0039] On the front side of the battery compartment 1.1, there is a stop block 1.1.4 located on the lower side of the housing 1 and fixedly connected to the bottom of the battery compartment 1.1. The stop block 1.1.4 extends from the battery compartment 1.1 towards the housing 1 along the length direction of the housing 1; the battery compartment 1.1 is provided with a stop block 1.1.4 extending along the length direction of the housing 1. One end of the stop block 1.1.4 is connected to the inner wall of the battery compartment 1.1 and the other end is suspended in the battery compartment 1.1. There is a gap 7 between the stop block 1.1.4 and the outer wall of the housing 1 and between the stop block 1.1.4 and the inner wall of the battery compartment 1.1. The door shaft enters the inner side of the housing 1 through the gap 7 between the stop block 1.1.4 and the outer wall of the housing 1. The gap between the stop block 1.1.4 and the inner wall of the battery compartment 1.1 is used to provide a space for accommodating the connecting member 3.1.2. When the battery door 3 is closed, the connecting member 3.1.2 is located within the gap between the stop block 1.1.4 and the inner wall of the battery compartment 1.1; a bottom tray 4 is detachably connected to the housing 1 below the stop block 1.1.4; an articulated activity space for accommodating the door shaft 3.1 is formed between the bottom tray and the housing 1.

[0040] A pair of fixing columns 1.1.7 are provided on both sides of the latch 1.1.10. The first fixing column is located on the inner side wall of the housing 1 and the second fixing column is located on the inner side wall of the stop block 1.1.4. The fixing columns 1.1.7 extend towards the inner side of the housing 1. The first fixing column and the second fixing column are located on both sides of the latch 1.1.10 and are used to fix the bottom tray 4. Two ends of the bottom tray 4 are respectively inserted into the first fixing column and the second fixing column.

[0041] The door hinge 3.1 is made of plastic. When installing the battery door 3, by utilizing the elasticity of the plastic, the door hinge 3.1 is inserted into the inner side of the housing 1 from the gap 7 between the stopper 1.1.4 and the outer wall of the housing 1, realizing the rotational connection between the battery door 3 and the housing 1. At one end of the battery door 3 away from the door hinge 3.1, a battery door buckle 3.3 is provided, and a buckle groove 1.1.5 corresponding to the position of the battery door buckle 3.3 is formed on the housing 1. During assembly, after the battery door 3 slides into the battery compartment along the guide rail 1.1.6 and is horizontally pushed into the housing 1, the door hinge 3.1 is inserted into the inner side of the housing 1 from the gap 7 between the stopper 1.1.4 and the inner wall of the battery compartment 1.1, crossing over the lock catch 1.1.10, and the battery door buckle 3.3 is inserted into the buckle groove 1.1.5, thereby realizing the locking of the battery door.

[0042] The lock catch 1.1.10 on the inner side of the housing 1 is a protrusion extending towards the inner side of the housing and provided in front of the battery compartment 1.1. The lock catch 1.1.10 is located on the path where the door hinge 3.1 slides into the inner side of the housing 1. When the latching amount is appropriate, it can achieve smooth and labor-saving opening of the battery door and reliable self-locking when closing the battery door.

[0043] On the base 4, two fixing holes 4.1 are provided corresponding to the first fixing column and the second fixing column. During installation, the two fixing holes 4.1 are directly aligned with the first fixing column and the second fixing column and pressed in. Through the interference fit between the hole and the column, the base 4 is reliably and firmly installed between the housing 1 and the stopper 1.1.4. Since the up-and-down floating space of the door hinge 3.1 of the battery door 3 in the housing 1 is large, if there is no restriction on its sinking, when the upper side of the battery door 3 is closely attached to the side wall of the battery compartment and rotates, and the space sufficient to replace the battery has not been opened yet, a rotation dead angle will appear and it will be locked. If one then tries to forcefully open the battery door, there is a certain probability of breaking the battery door hinge structure. During the rotation of the battery door 3, the base 4 restricts the sinking amount of the door hinge 3.1 and acts as a lifting support for the door hinge 3.1. Under the lifting support of the base 4, even if the upper side of the battery door 3 is closely attached to the side wall of the battery compartment and rotates, the battery door can be smoothly opened, eliminating the rotation dead angle.

[0044] The battery door is horizontally pulled out from the buckle groove 1.1.5 towards the rear of the housing 1 to disengage from the housing 1, and then rotates upwards and can stand reliably on the housing 1. A certain gap is left between the base 4 and the housing 1. During the rotation of the battery door, it lifts the rotating shaft, eliminates the rotation dead angle of the battery door, makes the battery door rotate smoothly, and avoids breaking the battery door hinge due to excessive force caused by jamming.

[0045] Such as Figure 4As shown, a number of battery pressing strips 3.2 extending towards the battery are provided on the inner side of the battery door 3. The battery pressing strips 3.2 are arranged corresponding to the center positions of the button batteries 5. When the battery door 3 is closed, the number of battery pressing strips 3.2 will exert a pressure on the button batteries 5 in the direction of the bottoms of the first installation groove 1.1.11 and the second installation groove 1.1.12, providing a second guarantee for the reliable contact between the button batteries 5 and the positive and negative spring pieces.

[0046] The battery compartment of the blood glucose meter in this embodiment adopts a simple positive and negative spring piece structure that can be automatically soldered on the SMT line; the distance between the two button batteries is made as small as possible, and a relief groove 1.1.1 is added in the middle on one side of the installation positions of the two button batteries to facilitate the removal of the batteries; by using the cooperation of the first battery buckle 1.1.2, the second battery buckle 1.1.3, the installation groove and the battery spring piece, the button batteries are reliably fixed in the battery compartment; and the battery door and the rear cover are designed to be connected by a rotating shaft. When the battery door is opened to install or remove the battery, the battery door and the rear cover remain connected, which not only avoids losing the battery door but also can use the front area of the battery door to display the nameplate information, making the tester compact, thin and light. At the same time, the bottom bracket installed under the rotating shaft of the battery door supports the rotating shaft of the battery door during the process of rotating and opening the battery door, eliminating the dead angle of movement, and making the rotation and flipping smooth after the battery door buckle 3.3 disengages from the buckle groove 1.1.5.
