Description

Technical Field

[0001] This utility model relates to the field of blood glucose meter technology, and in particular to a mid-layer support and a blood glucose meter. Background Technology

[0002] A blood glucose meter is a medical device used to measure the concentration of glucose in the blood. It is mainly used for daily blood glucose monitoring by diabetic patients, but can also be used for blood glucose screening in healthy individuals.

[0003] Portable blood glucose meters are a type of blood glucose meter that are small and easy to carry. They are generally equipped with batteries. Existing portable blood glucose meters usually fix the battery to the bottom shell with adhesives (such as high-viscosity foam), such as the portable blood glucose meter for internal medicine clinical use with patent number CN216318020U. This method of fixing the battery to the bottom shell with adhesives has the following drawbacks: the battery is only connected and fixed to the bottom shell by adhesives, and the adhesive strength of the adhesives is easy to decrease over time. In addition, the portable blood glucose meter is easy to swing when carried, causing the internal battery to swing with it. Since there is no force support on the side of the battery, it is easy for the battery to wobble.

[0004] Therefore, the existing technology still needs to be improved and enhanced. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a middle support and a blood glucose meter, which aims to solve the problem that when the battery inside the portable blood glucose meter is fixed in the bottom shell by adhesive, the adhesive strength of the adhesive tends to decrease over time, and the portable blood glucose meter is easy to swing when carried, causing the internal battery to shake. Since there is no force support on the side of the battery, the battery is prone to loosening.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: In a first aspect, embodiments of the present invention provide a mid-layer support, comprising: The bracket body has a battery slot on one side. Along the length of the battery slot, one end of the battery slot has an arched notch for holding the protrusion of the positive terminal of the cylindrical battery. The other end of the battery slot has a limiting rib on the inner side for abutting the end face of the negative terminal of the cylindrical battery. The support plate has an arc-shaped slot that fits the side of the cylindrical battery. Multiple support plates are provided in the battery slot. The support plates are arranged in a row along the length of the battery slot, with each support plate parallel to the others and evenly spaced. The arc-shaped slots on each support plate are aligned along the length of the battery slot.

[0007] Furthermore, the bracket body is provided with two battery slots, which are staggered, and one of the battery slots is provided with a first air tube limiting groove on its outer side.

[0008] Furthermore, the first tracheal limiting groove is provided with a first elastic locking protrusion.

[0009] Furthermore, a second air pipe limiting groove is provided on the other end face of both battery slots.

[0010] Furthermore, the bracket body has a small transformer slot on one side of the battery slot, the top of the small transformer slot is open, and the top of a set of opposite sides of the small transformer slot is respectively provided with a second elastic latching protrusion.

[0011] Furthermore, a third air pipe limiting groove is provided on the other set of opposite sides of the small transformer slot.

[0012] Furthermore, the bracket body is provided with a single-hole vent groove on one side of the battery slot, and a third elastic locking protrusion is provided on each of the two opposite sides of the single-hole vent groove, and a fourth air pipe limiting groove is provided at one end of the single-hole vent groove.

[0013] Furthermore, the bracket body is provided with a multi-hole vent groove on one side of the battery slot, and the side of the multi-hole vent groove is provided with a plurality of fifth air pipe limiting grooves; the two opposite sides of the multi-hole vent groove are respectively provided with fourth elastic locking protrusions.

[0014] Furthermore, a rectangular positioning frame is provided on the side of the bracket body away from the battery slot to limit the position of the backlight display module.

[0015] Secondly, this utility model embodiment also provides a blood glucose meter, which includes the middle layer support described in any one of the above-mentioned embodiments.

[0016] Compared with the prior art, the embodiments of this utility model have the following advantages: This utility model embodiment provides a middle layer support, including: a support body, a battery slot on one side of the support body, an arched notch at one end of the battery slot along the length direction of the battery slot for holding the protrusion of the positive terminal of the cylindrical battery, and a limiting rib on the inner side of the other end of the battery slot for abutting the end face of the negative terminal of the cylindrical battery; and a support piece, the support piece having an arc-shaped notch adapted to the side periphery of the cylindrical battery, and multiple support pieces arranged in the battery slot, the support pieces being parallel to each other and evenly spaced in a row along the length direction of the battery slot, and the arc-shaped notches on each support piece being aligned along the length direction of the battery slot. In this invention, after the cylindrical battery is fixed to the battery compartment by the adhesive, the arc-shaped notch on the support piece can provide radial support and limit the cylindrical battery, while the arched notch on the battery compartment and the limiting rib inside the battery compartment can provide axial support and limit the cylindrical battery.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] Example 1: Please see Figures 1-6 The middle layer support includes: a support body 1, with a battery slot 2 on one side of the support body 1. Along the length of the battery slot 2, one end of the battery slot 2 has an arched notch 201 for holding the protrusion of the positive terminal of the cylindrical battery, and the other end of the battery slot 2 has a limiting rib 202 for abutting the end face of the negative terminal of the cylindrical battery; and a support plate 3, with an arc-shaped notch 301 on the support plate 3 that is adapted to the side circumference of the cylindrical battery. Multiple support plates 3 are provided in the battery slot 2. The support plates 3 are arranged in a row parallel to each other and evenly spaced along the length of the battery slot 2, and the arc-shaped notches 301 on each support plate 3 are aligned along the length of the battery slot 2.

[0021] like Figure 1 and Figure 2 As shown, in this embodiment, the bracket body 1 is provided with a battery slot 2 for installing a cylindrical battery. One side of the battery slot 2 is open, and the remaining sides extend outwards perpendicular to the bracket body 1 to form the sidewall of the battery slot 2. Along the length of the battery slot 2, an arched latch 201 is provided at the left end of the battery slot 2. The arched latch 201 is used to hold the protrusion of the positive terminal of the cylindrical battery. The arc design of the arched latch 201 naturally conforms to the curved surface of the positive terminal of the cylindrical battery. When the cylindrical battery is subjected to external force (such as equipment vibration or drop), the inner wall of the arched latch 201 can disperse the impact force through its arc, reducing local pressure on the positive terminal protrusion of the cylindrical battery and preventing deformation or breakage of the positive terminal protrusion. For batteries that are repeatedly inserted and removed… This can extend its service life; and the battery slot 2 has an arched latch 201 on one side for holding the end face of the cylindrical battery with a protrusion. The diameter of the arched latch 201 is slightly larger than the diameter of the protrusion at the positive terminal of the cylindrical battery, for example, larger than 0.1mm-0.3mm. The slightly larger diameter of the arched latch 201 provides a suitable holding space for the protrusion of the positive terminal of the cylindrical battery to avoid the positive terminal from shaking in the battery slot, and also retains a small gap to accommodate the size tolerance of the protrusion of different brands of batteries. Usually, the diameter of the protrusion of the positive terminal of the cylindrical battery has an error of ±0.1mm, ensuring that the positive terminal of the cylindrical battery is always in the preset conductive position, avoiding circuit breakage and equipment power failure due to poor contact.

[0022] The battery slot 2 has a limiting rib 202 on the inner side of the right end. The limiting rib 202 is used to abut the end face of the negative terminal of the cylindrical battery. The negative terminal of the cylindrical battery is usually a flat or shallow concave surface. The limiting rib 202 directly abuts its end face. The assembly tolerance is absorbed by the slight elastic deformation of the limiting rib 202, which ensures that batteries of the same model with different lengths can be reliably fixed and avoids axial movement caused by excessive gaps. In addition, the contact area of ​​the limiting rib 202 is small, and the friction force when inserting or removing the cylindrical battery is less than that of full-plane contact, which makes it easy for users to take out or install the cylindrical battery.

[0023] The support plate 3 is provided with an arc-shaped slot 301 that adapts to the side circumference of the cylindrical battery. The radius of the arc-shaped slot 301 is the same as the radius of the arc of the side circumference of the cylindrical battery. Multiple support plates 3 are provided in the battery slot 2. The arc-shaped slot 301 has a guiding function, so when the user inserts the battery, there is no need to precisely align the position. The side circumference of the cylindrical battery can naturally slide into the preset position along the arc-shaped slot 301, reducing assembly resistance. The support plates 3 are arranged in rows parallel to each other and evenly spaced along the length direction of the battery slot 2, forming a multi-point support for the cylindrical battery. The cylindrical battery is prone to bending deformation under its own weight or external force. The evenly distributed support points can distribute the weight of the cylindrical battery and external stress to multiple positions, avoiding excessive force at a single point that could cause the cylindrical battery to bend. In addition, the arc-shaped slots 301 on each support plate 3 are aligned along the length direction of the battery slot 2, forming a constraint channel that is completely parallel to the axis of the cylindrical battery. This design ensures that the battery moves along a preset axis during installation, ultimately aligning the positive and negative terminals precisely with the electrode contacts at both ends of the battery slot. This prevents electrode misalignment caused by battery tilting and ensures the stability of circuit conduction. In this embodiment, after the cylindrical battery is fixed to the battery slot 2 with adhesive, the arc-shaped latch 301 on the support piece 3 provides radial support and limitation for the cylindrical battery. The arched latch 201 on the battery slot 2 and the limiting rib 202 inside the battery slot 2 provide axial support and limitation for the cylindrical battery. By cooperating with the arc-shaped latch 301, the arched latch 201, and the limiting rib 202 to support the cylindrical battery, the adhesive inside the battery slot 2 experiences less force and maintains its adhesion for a longer period when bonding the cylindrical battery. It also prevents the cylindrical battery from shaking in all directions during transportation, which helps to enhance the stability of the cylindrical battery.

[0024] As a further solution, the bracket body 1 is provided with two battery slots 2, which are staggered. If the two battery slots 2 are designed to be aligned side by side, they would require a horizontal space of twice the width of the bracket body (e.g., if a single battery slot 2 is 20mm wide, an aligned layout would require at least 40mm in width). However, the staggered arrangement can achieve partial overlap in the horizontal space by offsetting a portion of the length vertically (e.g., only 25-30mm in width is needed to accommodate the two battery slots 2). This staggered design is crucial for size-sensitive devices such as blood glucose meters, as it meets the high battery life requirements of dual-battery power supply without increasing the horizontal dimensions of the bracket body or even the entire device, ensuring the device's compactness and portability. Furthermore, one of the battery slots 2 has a first air tube limiting groove 4 on its outer side. Specifically, in this embodiment, the first air tube limiting groove 4 can clamp and limit the air tube used for heat dissipation inside the blood glucose meter, fixing the air tube and preventing displacement due to device movement, vibration, or assembly errors. This ensures that the air tube always maintains a smooth heat dissipation path, ensuring temperature stability of the device under different operating conditions and indirectly improving the accuracy of blood glucose measurement results.

[0025] As a further improvement, the first air tube limiting groove 4 is provided with a first elastic locking protrusion 401, which is used to secure the heat dissipation air tube. The outer diameter of the heat dissipation air tube typically has a certain manufacturing error (usually ±0.2mm). The first elastic locking protrusion 401, through its own elastic deformation (such as using a micro-protrusion structure made of plastic), can automatically adapt to heat dissipation air tubes of different outer diameters. When the heat dissipation air tube is slightly thicker, the first elastic locking protrusion 401 is slightly squeezed and deformed, generating sufficient clamping force through elasticity; when the heat dissipation air tube is slightly thinner, the first elastic locking protrusion 401 remains in its natural state, ensuring close contact with the surface of the heat dissipation air tube through its protrusion height. The blood glucose meter will vibrate during carrying or use. If the heat dissipation air tube relies solely on the static constraint of the first air tube limiting groove 4, it is prone to gradually loosening or even falling off due to long-term vibration. The first elastic locking protrusion 401, through continuous elastic pressure, adheres tightly to the surface of the heat dissipation air tube, forming a dynamic clamping effect.

[0026] In this embodiment, a second air pipe limiting groove 203 is provided on the other end face of both battery slots 2. The second air pipe limiting groove 203 is used to clamp the heat dissipation air pipe connected to the battery slot 2.

[0027] like Figure 3 As shown, as a further embodiment, the bracket body 1 is provided with a small transformer slot 5 on one side of the battery slot 2. The top of the small transformer slot 5 is open, and the top of a set of opposite sides of the small transformer slot 5 is provided with a second elastic locking protrusion 501. The second elastic locking protrusion 501 is used to lock the outside of the small transformer.

[0028] As a further improvement, a third air pipe limiting groove 502 is provided on the other set of opposite sides of the small transformer slot 5. The third air pipe limiting groove 502 is used to clamp the heat dissipation air pipe connected to the small transformer slot 5.

[0029] like Figure 4 As shown, in this embodiment, the bracket body 1 is provided with a single-hole vent slot 6 on one side of the battery slot 2. The single-hole vent slot 6 is used to accommodate the single-hole vent component. The two opposite sides of the single-hole vent slot 6 are respectively provided with a third elastic locking protrusion 601. One end of the single-hole vent slot 6 is provided with a fourth air pipe limiting groove 602. The third elastic locking protrusion 601 is used to press the single-hole vent component, and the fourth air pipe limiting groove 602 is used to clamp the heat dissipation air pipe connected to the single-hole vent component.

[0030] like Figure 5 As shown, as a further embodiment, the bracket body 1 has a multi-hole vent groove 7 on one side where the battery slot 2 is located. The multi-hole vent groove 7 is used to accommodate the multi-hole vent component. The side of the multi-hole vent groove 7 has multiple fifth air pipe limiting grooves 701, which are used to clamp the heat dissipation air pipes connected to the multi-hole vent component. The two opposite sides of the multi-hole vent groove 7 are respectively provided with fourth elastic locking protrusions 702, which are used to press the outer side of the multi-hole vent component.

[0031] like Figure 6 As shown, as a further solution, the bracket body 1 is provided with a rectangular positioning frame 8 on the side opposite to the battery slot 2, which is used to limit the backlight display module.

[0032] Example 2: This embodiment also provides a blood glucose meter, which includes the mid-layer support as described in any one of the embodiments.

[0033] In summary, this utility model embodiment provides a mid-layer support, comprising: a support body 1, a battery slot 2 on one side of the support body 1, an arched notch 201 at one end of the battery slot 2 along its length for holding the protrusion of the positive terminal of a cylindrical battery, and a limiting rib 202 on the inner side of the other end of the battery slot 2 for abutting the end face of the negative terminal of the cylindrical battery; and a support piece 3, which has an arc-shaped notch 301 adapted to the side circumference of the cylindrical battery. Multiple support pieces 3 are provided inside the battery slot 2, and the support pieces 3 are arranged in a row parallel to each other and evenly spaced along the length of the battery slot 2, with the arc-shaped notches 301 on each support piece 3 aligned along the length of the battery slot 2. In this invention, after the cylindrical battery is fixed to the battery compartment 2 by the adhesive, the arc-shaped notch 301 on the support piece 3 can provide radial support and limit the cylindrical battery, and the arched notch 201 on the battery compartment 2 and the limiting rib 202 in the battery compartment 2 can provide axial support and limit the cylindrical battery. By cooperating to support the cylindrical battery through the arc-shaped notch 301, the arched notch 201 and the limiting rib 202, the adhesive in the battery compartment 2 can be less stressed and the adhesion can be maintained for a longer time. It can also prevent the cylindrical battery from shaking in all directions during transportation, which is beneficial to strengthening the stability of the cylindrical battery.
