Description

Technical Field

[0001] This utility model relates to the field of cold chain transportation, and in particular to a temperature recorder fixing structure. Background Technology

[0002] In the cold chain transportation sector, repetitive IoT temperature loggers are key equipment for ensuring the quality of cold chain products. They can monitor and record the ambient temperature in real time during transportation, providing core data support for the safe traceability of cold chain products. However, in practical applications, traditional IoT temperature loggers, limited by power supply and fixed structural design flaws, are gradually becoming unable to meet the demands for high efficiency and stability in cold chain transportation.

[0003] In terms of power supply, existing repetitive IoT temperature loggers generally use dry cell batteries or lithium batteries as their power source. This power supply method directly determines that the device needs to be frequently removed from the cold chain insulation box for charging, and then reinstalled in its fixed position in the insulation box after it is fully charged. The device fixing process is precisely the most problematic part of the current technical solutions—existing products mainly rely on two structures for fixing, but both have obvious limitations.

[0004] One mainstream fixing method relies on the elastic deformation of engineering plastics to achieve snap-fit ​​fixation, directly locking the recorder housing in place through the elastic deformation of the plastic. This structure has significant drawbacks: while a large snap-fit ​​engagement can ensure a certain degree of stability, it makes removing the recorder extremely inconvenient. Furthermore, during forced disassembly, the hard plastic snaps can easily rub or collide with the recorder housing, causing scratches, wear, and even damage to internal components, shortening the device's lifespan. Conversely, a small snap-fit ​​engagement, while reducing the difficulty of removal, cannot provide sufficient fixing force. Under conditions of bumps and vibrations during cold chain transportation, the recorder can easily detach from the mounting bracket, leading to interrupted temperature monitoring and affecting the integrity of cold chain data. More importantly, this structure relies entirely on the elastic deformation of engineering plastics for fixation. Repeated loading and unloading operations over a long period can cause fatigue damage to the plastic. With prolonged use, the plastic snaps are prone to breakage, directly causing the entire fixing device to fail and become unusable.

[0005] Another common fixing method is using a pin tumbler mechanism. Compared to engineering plastic clips, pin tumblers offer improved durability and are less prone to breakage. However, they present a significant technical challenge in controlling the fixing force: if the pin's elasticity is too low, it cannot provide sufficient clamping force, and the recorder can easily detach from its mounting position under transport bumps or minor impacts; if the pin's elasticity is too high, while ensuring a secure fixation, it greatly increases the difficulty of removing the recorder, especially for operators with weaker hand strength (such as warehouse managers and logistics sorters), requiring considerable effort to pry the device out. This not only reduces loading and unloading efficiency but may also cause the device to slip and be damaged due to improper operation. This "dilemma of force" makes pin tumbler fixing unsuitable for the needs of different operators and unable to cope with complex scenarios such as vehicle vibration and environmental temperature changes during cold chain transportation (which may affect the lubrication and elasticity stability of the pins).

[0006] In recent years, with the rapid growth in consumer demand for cold chain products such as fresh food and pharmaceuticals, the scale of cold chain transportation has continued to expand, placing higher demands on the frequency of use, stability of installation, and ease of operation of temperature recorders. The problems of inconvenient loading and unloading, susceptibility to damage, and poor adaptability of the two aforementioned installation methods have seriously affected the efficiency of cold chain transportation and the reliability of temperature monitoring, making it increasingly difficult to meet the current large-scale, high-frequency cold chain transportation needs.

[0007] In view of this, it is necessary to improve the existing repetitive IoT temperature recorder fixing device to solve the problems caused by the above-mentioned fixing structure defects and adapt to the development needs of the cold chain industry. Utility Model Content

[0008] The purpose of this application is to solve the problems of inconvenient installation and removal, damage, and poor adaptability of traditional temperature recorders.

[0009] To achieve the above objectives, this application provides a temperature recorder fixing structure, including: a groove for placing the temperature recorder, and a buckle connected to the groove via a rotating shaft; one end of the buckle near the display surface of the temperature recorder is a bent holding part, which is used to fix the temperature recorder, and the buckle is provided with a protrusion facing and close to the temperature recorder, the protrusion being located between the temperature recorder and the groove.

[0010] When the fastening part is inserted into and fixed in the fastening groove, the protrusion moves away from the temperature recorder; when the fastening part is released and moves away from the fastening groove, the protrusion moves closer to and abuts against the temperature recorder.

[0011] More specifically, the fixing structure also includes a stop located below the buckle and facing the temperature recorder. When the fastening part is inserted into and fixed in the fastening groove, the protrusion approaches and abuts against the stop.

[0012] More specifically, it also includes a pin set on the stop block, a return spring with one end sleeved on the pin, and the other end of the return spring abutting against the other end of the buckle away from the fastening part.

[0013] More specifically, the temperature recorder has a retaining groove on its top, and the retaining part corresponds to the retaining groove.

[0014] More specifically, the side of the protrusion facing the temperature recorder is an inclined surface, and the inclined surface forms an obtuse angle with the inner surface of the buckle.

[0015] More specifically, the side of the holding part away from the holding groove has a first guide surface that is inclined toward the holding groove, and the back of the temperature recorder has an inclined second guide surface, with the first guide surface corresponding to the second guide surface.

[0016] More specifically, a limiting plate is provided at the bottom of the tank.

[0017] More specifically, the inner side of the groove is also provided with several ball structures.

[0018] More specifically, the temperature recorder is provided with a photosensitive element on its top, and the buckle is provided with a through hole corresponding to the photosensitive element.

[0019] More specifically, the bottom of the tank is provided with an interface for electrical connection with a temperature recorder.

[0020] More specifically, the groove is provided with a number of mounting holes.

[0021] The beneficial effects of this application are: through the innovative buckle structure, the temperature recorder can be firmly installed on the cabinet. During installation, the temperature recorder can be automatically locked and fixed after being pushed in by the inclined guide surface. During disassembly, the temperature recorder can be automatically pushed out by the internal protrusion. The fixing structure has the characteristics of long service life, high fixing stability, ingenious structural design, and convenient and quick operation. Users can complete the installation and disassembly work with only one hand, which greatly improves work efficiency. Attached Figure Description

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figure 1As shown, this application provides a fixing structure for securing a temperature recorder. The fixing structure includes: a groove 1 for placing the temperature recorder, and a buckle 2 connected to the groove 1 via a rotating shaft. The buckle 2 is located at the top of the groove 1. When the temperature recorder is placed inside the groove 1, the buckle 2 can be rotated to secure or release the temperature recorder via the rotating shaft. For a more stable locking effect, the end of the buckle 2 near the display surface of the temperature recorder is a bent retaining part 21. The retaining part 21 corresponds to the retaining groove of the temperature recorder, and when the buckle 2 is snapped down, the retaining part 21 can be locked precisely within the retaining groove. Figure 5 As shown, the side of the retaining part 21 away from the retaining groove can be designed as a first guide surface 31 inclined towards the groove 1. Simultaneously, the back of the temperature recorder has an inclined second guide surface 32. This facilitates the placement of the temperature recorder; the temperature recorder only needs to be pushed into the groove 1 to allow the buckle 2 to rotate upwards around its axis using the inclined guide surface. Both the retaining part 21 and the rear of the temperature recorder are inclined surfaces. During the pressing of the temperature recorder, due to the inclined surface design, the buckle 2 will rotate upwards along the inclined surface, allowing the temperature recorder to smoothly enter the groove 1 without needing to manually push the buckle 2 upwards to complete the installation operation.

[0033] To facilitate the disassembly of the temperature recorder, such as Figure 2 As shown, the buckle 2 is provided with a protrusion 22 facing and close to the temperature recorder. When the buckle 2 is locked, the protrusion 22 will not hold the temperature recorder. When the buckle 2 rotates upward around the axis to release the temperature recorder, the protrusion 22 will hold the temperature recorder and push it outward from the outside of the tank 1. At this time, the user will not need to pry open the tightly sealed tank 1 to remove the temperature recorder. The user only needs to grasp the exposed part that has been pushed out to easily remove the temperature recorder.

[0034] In some specific embodiments, the fixing structure also includes a stop 23 located below the latch 2 facing the temperature recorder, a pin 24 disposed on the stop 23, and a return spring 25 with one end sleeved on the pin 24. The other end of the return spring 25 abuts against the other end of the latch 2 away from the holding part 21. With the help of the elastic force of the return spring 25, the latch 2 will have a more stable locking ability and automatic reset ability. When the holding part 21 is inserted and fixed in the holding groove, the protrusion 22 approaches and abuts against the stop 23. The stop 23 can block the protrusion 22 and keep the latch 2 parallel even when the temperature recorder is not installed, reducing the extra operation required to lift the latch 2 when installing the temperature recorder. The stop 23 can also prevent the latch 2 from rotating downwards excessively and damaging the return spring 25.

[0035] like Figures 2 to 5As shown, in some specific embodiments, the side of the protrusion 22 facing the temperature recorder is an inclined surface, and the inclined surface forms an obtuse angle with the inner surface of the buckle 2. The obtuse angle structure can prevent the temperature recorder from being accidentally stuck between the buckle 21 and the protrusion 22, and can ensure that the temperature recorder is gradually pushed out by the protrusion 22 (if the protrusion 22 immediately abuts against the temperature recorder when the buckle 2 rotates upward, the temperature recorder may be stuck).

[0036] In some specific embodiments, a limiting plate 12 is also provided at the bottom of the tank 1. The limiting plate 12 can restrict the temperature recorder and prevent the lower part from leaving the tank 1. When the protrusion 22 is pushed outward, the limiting plate 12 can act as a lower fulcrum, so that only the upper part is pushed out, making it easy for the user to pick up.

[0037] In some specific embodiments, a number of ball structures 11 are also provided on the inner side of the tank 1. The ball structures 11 are symmetrically distributed on the working side wall of the tank 1, which can help fix the temperature recorder.

[0038] In some specific embodiments, the aforementioned fixing structure is applied to the enclosure, for example, it can be fixed to the foam layer of the enclosure through several mounting holes in the groove 1. The inner surface of the groove 1 can also be provided with a label groove for affixing labels to identify information such as the enclosure number and temperature recorder number.

[0039] In some specific embodiments, the bottom of the tank 1 is provided with an interface for electrical connection with a temperature recorder, through which temperature changes inside the chamber can be directly detected.

[0040] In some specific embodiments, a photosensitive element is provided on the top of the temperature recorder, and a through hole 26 corresponding to the photosensitive element is also provided on the buckle 2. When the buckle 2 fixes the temperature recorder, the photosensitive element can sense whether the box is completely covered through the through hole 26 (the through hole 26 will be blocked when the box is covered).

[0041] like Figure 6 As shown, the temperature recorder fixing structure designed in this application completes the portable installation and fixing and automatic disassembly functions of the temperature recorder through the movable and automatically reset buckle 2 and the protrusion 22 inside the buckle 2. The user can install the temperature recorder on the box with only one hand and easily complete the disassembly operation with only one hand.

[0042] The embodiments of this utility model have been described in detail above, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
