Description

Technical Field

[0001] This utility model belongs to the field of temperature and humidity detection, specifically relating to a temperature and humidity recorder that is easy to install and disassemble. Background Technology

[0002] In the field of pharmaceutical cold chain transportation, insulated boxes are commonly used to transfer medicines, vaccines, blood products, and other items. To ensure the quality of these items during transportation, temperature and humidity data loggers are needed to monitor the temperature and humidity of the insulated boxes in real time. However, most existing temperature and humidity data loggers are either embedded or threaded, directly embedded in the inner wall of the insulated box or fixed to the inside of the box with screws. This makes installation and removal difficult, leading to challenges in later maintenance.

[0003] In existing technologies, such as patent document CN213543644U, a combined temperature and humidity recorder is disclosed. By dividing the base plate into multiple areas, the various components inside the temperature and humidity recorder are made independent, improving the convenience of maintenance. However, this temperature and humidity recorder needs to be fixed to the mounting location by screws passing through mounting holes. When the temperature and humidity recorder needs to be disassembled for maintenance, the fixing screws need to be removed, which is inconvenient. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model proposes a temperature and humidity recorder that is easy to install and remove. The base and the mounting base on which the recorder body is installed are detachably connected by a slot, a hook, and a clearance groove. When the recorder body needs to be installed or removed, it can be installed in or removed from the insulation box by simply pressing and rotating.

[0005] This utility model is implemented as follows: a temperature and humidity recorder that is easy to install and disassemble includes a recorder body, a base fixed to an insulation box, and a mounting base detachably connected to the base, wherein the recorder body is mounted on the mounting base.

[0006] The base has a slot on its periphery, and the mounting base has a hook that matches the slot. The base also has a clearance groove on its periphery corresponding to the hook, extending along the axial direction of the base. The hook is inserted into the slot through the clearance groove and engages with the slot by rotation. The engagement of the hook and slot creates a detachable connection between the mounting base and the base, allowing for quick installation or removal of the recorder and improving the convenience of later maintenance. The clearance groove provides a channel for the hook to enter and exit the slot, making it easier to connect or remove the mounting base from the base, further improving the ease of installation and removal of the temperature and humidity recorder.

[0007] The base is also equipped with an anti-loosening mechanism, which includes an anti-loosening plate. When the hook engages with the slot, the anti-loosening plate presses the hook against the side wall of the slot. The anti-loosening plate increases the friction between the hook and the slot by pressing, making the engagement tighter and preventing the hook from slipping out of the slot due to loosening of the mounting base, thus improving the reliability of the connection between the hook and the slot.

[0008] Preferably, each of the clearance grooves gradually increases in size from the inside out, forming a guide portion, which is flared in shape. The guide portion is used to guide the hook when it enters the clearance groove, making it easier for the hook to enter the clearance groove, thereby improving the convenience of connecting the mounting base and the base.

[0009] Specifically, the guide opening extends to the end face of one end of the base, and the opening size of multiple guides occupies more than 80% of the circumference of the end face, expanding the guiding range of the guide and making it easier for the hook to enter the guide when the mounting base is installed, further improving the convenience of connecting the mounting base and the base.

[0010] Preferably, the anti-loosening mechanism further includes an elastic unit, which is sleeved within the slot, with one end abutting against the inner wall of the slot and the other end elastically connected to the anti-loosening plate. The elastic unit applies a continuous pre-pressure to the anti-loosening plate to ensure that the anti-loosening plate can continuously abut against the hook, improving the reliability of the anti-loosening plate and also increasing its pressure resistance, thus enhancing its anti-loosening effect.

[0011] Preferably, the slot is further provided with a limiting part corresponding to the hook. When the hook is engaged in the slot, the side of the hook abuts against the limiting part. The limiting part is used to limit the engagement of the hook with the slot. When the hook engages with the slot, it needs to enter the slot from the clearance groove and then be engaged in the slot by rotation. Since there are multiple clearance grooves, if the hook rotates too much, there is a risk that the hook will come out of the next clearance groove. The limiting part is used to prevent the hook from coming out of the next clearance groove, thereby improving the reliability of the slot.

[0012] Specifically, the anti-loosening plate is provided with a guide groove corresponding to the limiting part. The guide groove engages with the limiting part, causing the anti-loosening plate to reciprocate along the extension direction of the limiting part. The guide groove guides the movement of the anti-loosening plate, improves the repeatability of the anti-loosening plate, and prevents misalignment due to movement when the anti-loosening plate presses against the hook, thereby improving the anti-loosening effect of the anti-loosening plate.

[0013] Preferably, the hook has a first transition portion that gradually decreases in size from bottom to top on its side, and the clearance groove has a second transition portion that matches the first transition portion. When the mounting base is removed, the first transition portion and the second transition portion are wedge-connected. On the one hand, since the hook needs to squeeze the anti-loosening plate when connecting with the slot to form a channel between the anti-loosening plate and the inner wall of the slot for the hook to engage, and the resistance of the anti-loosening plate needs to be overcome during installation, the first and second transition portions allow the hook to gradually increase the size of the channel during engagement with the slot, thereby reducing the initial size of the channel, reducing the resistance of the anti-loosening plate that needs to be overcome during installation, and improving installation convenience. On the other hand, when the mounting base is removed, the hook can gradually detach from the slot, preventing the mounting base from suddenly coming out of the slot during removal, which could cause the mounting base to slip and fall, thus improving the safety of the mounting base.

[0014] Preferably, the mounting base also has a recessed mounting portion. When the mounting base is connected to the base, the mounting portion is sleeved on the end of the base, and the inner wall of the mounting portion fits against the outer wall of the end of the base. The mounting portion sleeved on the end of the base increases the contact area when the mounting base and the base are connected, thus improving the stability of the connection. The close fit between the inner wall of the mounting portion and the outer wall of the end of the base allows for guidance when the mounting base rotates relative to the base, improving the concentricity between the mounting base and the base, and consequently improving the accuracy of the engagement between the hook and the slot.

[0015] Preferably, the bottom periphery of the base extends outward to form a fixing part, and the fixing part is further provided with a plurality of evenly distributed adjustment grooves. The adjustment grooves are arc-shaped and penetrate through the fixing part. Since dimensional and installation errors are unavoidable, the recorder body may tilt clockwise or counterclockwise after installation due to the accumulation of dimensional and installation errors. The adjustment grooves are used to provide adjustment margin for the installed recorder body, allowing the entire temperature and humidity recorder to be adjusted clockwise and counterclockwise, thus preventing the recorder body from tilting due to dimensional and installation errors.

[0016] Preferably, the mounting base further includes a fixing part that is fixedly connected to the recorder body. The fixing part has fixing holes on both sides. The set screws fix the recorder body to the mounting base through the fixing holes. When the recorder body needs to be installed on the mounting base or removed from the mounting base, it is only necessary to tighten or loosen the set screws, which improves the convenience of connecting the recorder body and the mounting base.

[0017] The beneficial effects of this utility model are:

[0018] This utility model proposes a temperature and humidity recorder that is easy to install and disassemble. On the one hand, the base and the mounting seat on which the recorder body is installed are detachably connected by a slot, a hook, and a clearance groove. The clearance groove provides a channel for the hook to enter and exit the slot. When the recorder body needs to be installed or removed, it can be installed in or removed from the insulation box by simply pressing and rotating. On the other hand, the anti-loosening mechanism increases the friction between the hook and the slot, thereby improving the reliability of the connection between the hook and the slot.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-7 As shown, a temperature and humidity recorder that is easy to install and disassemble includes a recorder body 3, a base 1 fixed to an insulated box, and a mounting base 2 detachably connected to the base 1. The recorder body 3 is mounted on the mounting base 2.

[0030] The base 1 has a slot 11 around its periphery, the mounting base 2 has a hook 21 that matches the slot 11, and the base 1 has a relief groove 12 that corresponds to the hook 21 around its periphery. The relief groove 12 extends along the axial direction of the base 1.

[0031] The hook 21 is inserted into the slot 11 through the clearance groove 12 and engages with the slot 11 by rotation. The engagement of the hook 21 and the slot 11 creates a detachable connection between the mounting base 2 and the base 1, allowing the recorder body 3 to be quickly installed or removed, thus improving the convenience of later maintenance. The clearance groove 12 provides a channel for the hook 21 to enter and exit the slot 11, making it easier for the mounting base 2 to connect or disconnect from the base 1, further improving the ease of installation and removal of the temperature and humidity recorder.

[0032] In this embodiment, each of the clearance grooves 12 gradually increases in size from the inside out, forming a guide portion 121, which is flared in shape. The guide portion 121 is used to guide the hook 21 when it enters the clearance groove 12, making it easier for the hook 21 to enter the clearance groove 12, thereby improving the convenience of connecting the mounting base 2 and the base 1.

[0033] Specifically, the opening of the guide portion 121 extends to the end face of one end of the base 1, and the opening size of the multiple guide portions 121 occupies more than 80% of the circumference of the end face, thereby expanding the guiding range of the guide portion 121. This makes it easier for the hook 21 to enter the guide portion 121 when the mounting base 2 is installed, further improving the convenience of connecting the mounting base 2 and the base 1.

[0034] In this embodiment, the side of the hook 21 is provided with a first transition portion 211 that gradually decreases from bottom to top, and the clearance groove 12 is provided with a second transition portion 122 that is adapted to the first transition portion 211. When the mounting base 2 is removed, the first transition portion 211 and the second transition portion 122 are wedge-connected. On the one hand, since the hook 21 needs to squeeze the anti-loosening plate 41 when connecting with the slot 11, a channel for the hook 21 to engage is formed between the anti-loosening plate 41 and the inner wall of the slot 11. During installation, the resistance of the anti-loosening plate 41 needs to be overcome. The first transition part 211 and the second transition part 122 can gradually increase the size of the channel during the engagement of the hook 21 with the slot 11, thereby reducing the initial size of the channel, reducing the resistance of the anti-loosening plate 41 that needs to be overcome during installation, and improving the ease of installation. On the other hand, when removing the mounting base 2, the hook 21 can gradually detach from the slot 11, preventing the mounting base 2 from instantly coming out of the slot 11 during removal, which would cause the mounting base 2 to slip and fall, thus improving the safety of the mounting base 2.

[0035] In this embodiment, the mounting base 2 is further provided with a recessed mounting portion 22. When the mounting base 2 is connected to the base 1, the mounting portion 22 is sleeved on the end of the base 1, and the inner wall of the mounting portion 22 is in contact with the outer wall of the end of the base 1. The mounting portion 22 sleeved on the end of the base 1 increases the contact area when the mounting base 2 is connected to the base 1, thereby improving the stability of the connection between the mounting base 2 and the base 1. The close contact between the inner wall of the mounting portion 22 and the outer wall of the end of the base 1 can guide the mounting base 2 when it rotates relative to the base 1, improving the concentricity between the mounting base 2 and the base 1, and thus improving the accuracy of the engagement between the hook 21 and the slot 11.

[0036] In this embodiment, the base 1 extends outward from its bottom periphery to form a fixing part 14. The fixing part 14 is also provided with a plurality of evenly distributed adjustment grooves 141. These adjustment grooves 141 are arc-shaped and penetrate the fixing part 14. Since dimensional and installation errors are unavoidable, the cumulative effect of these errors may cause the recorder body 3 to tilt clockwise or counterclockwise after installation. The adjustment grooves 141 provide adjustment margin for the installed recorder body 3, allowing the entire temperature and humidity recorder to be adjusted clockwise and counterclockwise, thus preventing the recorder body 3 from tilting due to dimensional and installation errors.

[0037] In this embodiment, the mounting base 2 further includes a fixing part 23 that is fixedly connected to the recorder body 3. The fixing part 23 has fixing holes 231 on both sides. The set screws fix the recorder body 3 to the mounting base 2 through the fixing holes 231. When the recorder body 3 needs to be installed on the mounting base 2 or removed from the mounting base 2, it is only necessary to tighten or loosen the set screws, which improves the convenience of connecting the recorder body 3 and the mounting base 2.

[0038] The base 1 is also provided with an anti-loosening mechanism 4, which includes an anti-loosening plate 41. When the hook 21 is engaged with the slot 11, the anti-loosening plate 41 presses the hook 21 against the side wall of the slot 11. By pressing, the anti-loosening plate 41 increases the friction between the hook 21 and the slot 11, making the engagement tighter and preventing the mounting base 2 from loosening and causing the hook 21 to come out of the slot 11, thus improving the reliability of the connection between the hook 21 and the slot 11.

[0039] In this embodiment, the anti-loosening mechanism 4 further includes an elastic unit 42, which is sleeved within the slot 11, with one end abutting against the inner wall of the slot 11 and the other end elastically connected to the anti-loosening plate 41. The elastic unit 42 applies a continuous pre-pressure to the anti-loosening plate 41 to ensure that the anti-loosening plate 41 can continuously abut against the hook 21, thereby improving the reliability of the anti-loosening plate 41 and increasing its abutting force, thus enhancing its anti-loosening effect.

[0040] In this embodiment, the elastic unit 42 can be a compression spring.

[0041] In this embodiment, the slot 11 is further provided with a limiting part 13 corresponding to the hook 21. When the hook 21 is engaged in the slot 11, the side of the hook 21 abuts against the limiting part 13. The limiting part 13 is used to limit the engagement of the hook 21 with the slot 11. When the hook 21 is engaged with the slot 11, it needs to enter the slot 11 from the clearance groove 12 and then be engaged in the slot 11 by rotation. Since there are multiple clearance grooves 12, when the rotation of the hook 21 is too large, there is a risk that the hook 21 will come out of the next clearance groove 12. The limiting part 13 is used to prevent the hook 21 from coming out of the next clearance groove 12, thereby improving the reliability of the slot 11.

[0042] Specifically, the anti-loosening plate 41 is provided with a guide groove 411 corresponding to the limiting part 13. The guide groove 411 engages with the limiting part 13, causing the anti-loosening plate 41 to reciprocate along the extending direction of the limiting part 13. The guide groove 411 guides the movement of the anti-loosening plate 41, improves the repeatability of the anti-loosening plate 41, and prevents misalignment caused by movement when the anti-loosening plate 41 presses against the hook 21, thereby improving the anti-loosening effect of the anti-loosening plate 41.

[0043] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
