Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a temperature and humidity sensor with drop resistance. Background Technology

[0002] In modern industrial and outdoor monitoring fields, temperature and humidity sensors have become indispensable devices, widely used in environmental monitoring, warehouse management, and agriculture. However, these scenarios often involve harsh operating environments, such as high-altitude installation, frequent movement, or vibration and shock. In such cases, the sensor's drop resistance is crucial, directly affecting the device's lifespan and reliability. While existing temperature and humidity sensors have made some progress in measurement accuracy and data transmission technology, their structural design is relatively weak in terms of drop resistance, revealing many shortcomings.

[0003] Most sensor housings are designed primarily to protect internal components, but lack effective cushioning structures. When the device is dropped or subjected to external force, the impact is directly transmitted to the delicate internal electronic components, causing damage or even rendering them unusable. This design is particularly inadequate for complex environmental conditions, especially in industrial or field measurement scenarios. While some sensors have attempted to enhance drop resistance by thickening the housing, the effect is limited, increasing the weight of the device without truly addressing the issue of impact energy transmission. To address these problems, those skilled in the art have proposed drop-resistant temperature and humidity sensors to solve these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a temperature and humidity sensor with drop resistance, which aims to improve the problem that most sensor housing designs are mainly aimed at protecting internal components, but lack an effective cushioning structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A temperature and humidity sensor with drop resistance includes a sensor body, a display screen mounted on the top of the sensor body, a button on the front of the top of the sensor body, a ventilation opening on the front of the sensor body, a probe connected to the front of the sensor body, drop-proof components on both the left and right sides of the sensor body, and snap-fit ​​components on both the left and right sides inside the sensor body.

[0007] The anti-fall component includes a mounting block, with inserts fixedly connected to the bottom front and rear sides of the mounting block. Limiting blocks are slidably connected to the interior front and rear sides of the mounting block. A spring is installed inside the mounting block. A connecting rod is rotatably connected to the top of the limiting block. Anti-fall plates are rotatably connected to the top of the connecting rod on the front and rear sides. Two slots are opened on the left and right sides of the sensor body.

[0008] Furthermore, the buckle assembly includes two limiting grooves, which are respectively opened on the front and rear sides inside the sensor body. A second spring is provided inside the limiting groove, and a second limiting block is slidably connected inside the limiting groove. A locking block is fixedly connected to the adjacent side of the two second limiting blocks, and a pull rope is fixedly connected to the opposite side of the two second limiting blocks. A knob is rotatably connected inside the sensor body, and a locking groove is opened inside the insertion block.

[0009] Furthermore, the two ends of the spring are respectively fixedly connected to the adjacent side of the front and rear limiting blocks, and the outside of the insert block matches the inside of the slot.

[0010] Furthermore, one end of the second spring is fixedly connected to the outside of the second limiting block, and the other end of the second spring is fixedly connected to the inner wall of the limiting groove.

[0011] Furthermore, the exterior of the card block matches the interior of the card slot, and the adjacent sides of the pull ropes on both the front and rear sides are fixedly connected to the exterior of the knob.

[0012] Furthermore, the sensor body is provided with multiple mounting bolts on its exterior for mounting and fixing the sensor body.

[0013] Furthermore, the drop shield is made of polycarbonate composite material, and the surface of the drop shield is provided with anti-slip texture.

[0014] Furthermore, a dustproof mesh is installed inside the vent to prevent dust or particulate matter from entering the sensor body.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, through the anti-drop component and spring buffer design, limiting blocks and elastic connection structures are installed on the left and right sides of the sensor. The cooperation of the spring and the limiting block effectively disperses external impact, protecting the sensor body and internal components from damage. Compared to the rigid and inflexible protective structures of existing technologies, this design improves drop resistance and avoids direct damage to the sensor upon drop.

[0017] 2. In this utility model, the elastic locking of the buckle assembly and the knob-pulling unlocking structure enable quick assembly and disassembly of the anti-fall component. The cooperation of the limiting groove, spring two, and the locking block makes the protective component both stable and easy to maintain. Traditional technical solutions for similar protective structures usually require tools for disassembly, which is inconvenient for users. This invention optimizes the convenience of the device, solves the problem of cumbersome installation and maintenance, and improves the applicability and user-friendliness of the equipment.

[0024] 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 some embodiments of the present utility model, and not all embodiments. 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.

[0025] Reference Figure 1 and Figure 2An embodiment of this utility model provides a temperature and humidity sensor with drop resistance, comprising a sensor body 1, a display screen 3 mounted on the top of the sensor body 1, a button 4 provided on the front side of the top of the sensor body 1, a ventilation opening 5 on the front side of the sensor body 1, a dustproof mesh installed inside the ventilation opening 5 to prevent dust or particles from entering the sensor body 1, a probe 6 connected to the front side of the sensor body 1, and multiple mounting bolts 2 provided on the outside of the sensor body 1 for mounting and fixing the sensor body 1.

[0026] Specifically, a display screen 3 is mounted on the top of the sensor body 1 to display real-time ambient temperature and humidity data. The outer surface of the display screen 3 is covered with a scratch-resistant coating made of a material with a hardness of not less than 9H to improve the durability and impact resistance of the display screen 3. A button 4 is located on the front top of the sensor body 1. The button 4 is used for function selection and parameter adjustment. The button 4 is encapsulated in silicone material, providing waterproof and dustproof performance. A ventilation opening 5 is located on the front of the sensor body 1. A dustproof mesh made of high-density stainless steel with a mesh diameter of 0.2 to 0.5 mm effectively prevents dust or particles from entering the sensor body 1, ensuring the accuracy and stability of the sensor measurement. A probe 6 is connected to the front of the sensor body 1. The probe 6 adopts a modular design, including a temperature probe and a humidity probe. The probe 6 is connected to the sensor body 1 through a standardized interface for easy disassembly, replacement, or maintenance. The probe 6 is covered with a protective shell made of polycarbonate material to further improve its drop resistance. Multiple mounting bolts 2 are also provided on the outside of the sensor body 1 to securely install the sensor body 1 in the operating environment, ensuring the stability and safety of the equipment during use.

[0027] Reference Figure 1 and Figure 2 The sensor body 1 has anti-drop components 7 on both the left and right sides. The anti-drop components 7 include mounting blocks 701. The bottom front and rear sides of the mounting block 701 are fixedly connected to the insert blocks 702. The front and rear sides of the mounting block 701 are slidably connected to the limit blocks 703. The mounting block 701 has a spring 704 inside. The two ends of the spring 704 are fixedly connected to the adjacent side of the limit blocks 703 on the front and rear sides respectively. The top of the limit blocks 703 is rotatably connected to the connecting rod 705. The top of the connecting rod 705 on the front and rear sides is rotatably connected to the anti-drop plate 706. The anti-drop plate 706 is made of polycarbonate composite material. The surface of the anti-drop plate 706 is provided with anti-slip texture. The sensor body 1 has two slots 707 on both the left and right sides. The outside of the insert block 702 matches the inside of the slot 707.

[0028] Specifically, the sensor body 1 is equipped with anti-drop components 7 on both the left and right sides. Each anti-drop component 7 includes a mounting block 701, which is fixedly connected to the slot 707 of the sensor body 1 via an insert 702. The exterior of the insert 702 matches the interior of the slot 707, ensuring the stability of the mounting block 701. Limiting blocks 703 are slidably connected to the front and rear sides of the mounting block 701. The sliding of the limiting blocks 703 within the mounting block 701 is elastically supported by springs 704. The two ends of the springs 704 are fixedly connected to the adjacent side of the limiting blocks 703 on both sides, absorbing and dispersing external impact through elastic deformation, further improving the anti-drop performance of the sensor body 1. A connecting rod 705 is rotatably connected to the top of the limiting blocks 703. The top of the connecting rod 705 is rotatably connected to an anti-drop plate 706, which is made of polycarbonate composite material. This material has high strength and toughness, effectively resisting external impact. The surface of the drop guard 706 is textured with anti-slip material, which can prevent the sensor from slipping or shifting during a fall, thereby further reducing the risk of secondary damage.

[0029] Reference Figures 2-4 The sensor body 1 has a buckle assembly 8 on both the left and right sides inside. The buckle assembly 8 includes two limiting grooves 801, which are respectively opened on the front and rear sides inside the sensor body 1. A second spring 802 is installed inside the limiting groove 801. A second limiting block 803 is slidably connected inside the limiting groove 801. One end of the second spring 802 is fixedly connected to the outside of the second limiting block 803, and the other end of the second spring 802 is fixedly connected to the inner wall of the limiting groove 801. A locking block 804 is fixedly connected to the adjacent side of the two second limiting blocks 803, and a pull rope 806 is fixedly connected to the opposite side of the two second limiting blocks 803. A knob 807 is rotatably connected inside the sensor body 1. The adjacent side of the pull rope 806 on the front and rear sides is fixedly connected to the outside of the knob 807. A slot 805 is opened inside the insert block 702, and the outside of the locking block 804 matches the inside of the slot 805.

[0030] Specifically, the sensor body 1 has locking assemblies 8 on both the left and right sides inside. These assemblies 8 secure the anti-drop component 7 and provide a stable, impact-resistant connection structure. Each locking assembly 8 includes two limiting grooves 801, located on the front and rear sides of the sensor body 1. A limiting block 803 is slidably connected inside each limiting groove 801, allowing it to move within the groove in a sliding direction. A spring 802 is installed inside each limiting groove 801. One end of the spring 802 is fixedly connected to the outside of the limiting block 803, and the other end is fixedly connected to the inner wall of the limiting groove 801. The elasticity of the spring 802 allows the limiting block 803 to automatically reset, ensuring that the locking assembly 8 can effectively lock or release the anti-drop component 7. Each of the two limiting blocks 803 has a locking block 804 fixedly connected to its adjacent side. The outer side of the locking block 804 matches the inner slot 805 of the insert block 702. When the locking block 804 is inserted into the slot 805, the drop-proof component 7 is firmly connected to the sensor body 1, forming a stable drop-proof structure. Each of the two limiting blocks 803 has a pull rope 806 fixedly connected to its opposite side. The pull rope 806 can be controlled by a knob 807. When the knob 807 is rotated, it drives the pull rope 806 to pull the limiting block 803, causing the locking block 804 to disengage from the slot 805, thus facilitating the user to quickly disassemble the drop-proof component 7.

[0031] Working Principle: First, when the sensor is subjected to external impact or drop, the drop protection plate 706 of the drop protection component 7 is the first to come into contact with the external force. Made of polycarbonate composite material, the drop protection plate 706 has high strength and toughness, capable of resisting initial impact. Simultaneously, the drop protection plate 706 is connected to the limiting block 703 via the connecting rod 705. The limiting block 703 slides inside the mounting block 701. The spring 704 inside the mounting block 701 undergoes elastic deformation as the impact force is transmitted, effectively reducing the impact force on the sensor body 1 by absorbing and dispersing the impact energy. Furthermore, the anti-slip texture design reduces slippage or displacement when the device is dropped, preventing secondary damage.

[0032] Secondly, the drop protection component 7 is fixedly connected to the sensor body 1 via the snap-fit ​​component 8. The snap-fit ​​block 804 is inserted into the slot 805 inside the insert block 702 to ensure stable installation of the drop protection component 7. The snap-fit ​​block 804 is fixed in the limiting groove 801 by the limiting block 803 and is elastically supported by the spring 802 to achieve automatic reset. When it is necessary to disassemble the drop protection component 7, the user can rotate the knob 807 inside the sensor body 1. The knob 807 drives the pull rope 806 to pull the limiting block 803 to the unlock position, so that the snap-fit ​​block 804 disengages from the slot 805, thereby easily completing the disassembly of the drop protection component 7.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
