Description

Technical Field

[0001] This utility model relates to the field of humidity sensor technology, specifically to a humidity sensor that is easy to install. Background Technology

[0002] Temperature and humidity, as fundamental environmental factors, are closely related to all aspects of daily production and life. For example, temperature and humidity can directly affect the comfort of the living environment and the pass rate of finished products. Temperature and humidity sensors are a type of sensor that measures the temperature and humidity in the air using a specific detection device. After measuring the temperature and humidity, the sensor converts the data into electrical signals or other required forms of information output according to a certain rule to meet user needs. Temperature and humidity sensors are among the most commonly used environmental factor acquisition devices, offering advantages such as high accuracy, ease of operation, good real-time performance, and cost-effectiveness.

[0003] For example, patent CN208780229U discloses a temperature and humidity sensor base that is easy to install. It includes a base body, a support base located at the bottom of the base body, and a suction cup device detachably connected to the support base. The suction cup device includes a suction cup cover, a latch, a suction cup, and a connector that passes through the suction cup and connects to the latch. The support base includes a support base body and a recess within the support base body. A retaining rib is provided in the recess and engages with the base body. The base body includes a housing, a fixed base, a partition, a temperature and humidity sensing element, a micro battery, and a micro resistor. The fixed base is fixed to the bottom of the housing. A support plate for the partition is provided on the fixed base. One end of the temperature and humidity sensing element and a tension spring are both located on the fixed base. A guide plate is fixed vertically on the partition. The micro battery is located within the fixed base. The purpose of this invention is to provide a temperature and humidity sensor base that is easy to install, making the installation of the temperature and humidity sensor convenient and quick.

[0004] However, the aforementioned easy-to-install temperature and humidity sensor base relies on a suction cup device for fixation. Its core compatibility is limited to smooth and flat flat surfaces (such as glass, ceramic tiles, and smooth metal panels). In core application scenarios such as industrial production and HVAC, the installation environment is often more complex. On the one hand, if the surface of the carrier has textures, rust, or unevenness (such as the frosted panel of an industrial cabinet or the outer wall of a pipe), the suction cup cannot form an effective seal, which can easily lead to the risk of falling off and resulting in insufficient stability of the sensor after installation. On the other hand, for scenarios that need to be installed on non-planar carriers such as the side of a pipe or equipment bracket, the suction cup device is completely unsuitable and requires an additional adapter structure, which increases the installation complexity. In addition, the support base and the base body use a snap-fit ​​connection structure, which, although enabling detachment, has a fixed snap-fit ​​position and cannot adjust the installation spacing according to the size and specifications of the sensor. If different models of temperature and humidity sensing elements are replaced later, installation will be impossible due to size mismatch, reducing the versatility of the base. Utility Model Content

[0005] The purpose of this utility model is to provide a humidity sensor that is easy to install, in order to solve the problems mentioned in the background art, which are limited in the applicable scenarios due to the reliance on suction cup fixation, and cannot be stably installed on carriers with textured, rusty or uneven surfaces (such as the frosted panel of industrial cabinets, the outer wall of pipes) as well as non-planar carriers such as the side of pipes and equipment brackets. Furthermore, the support base and the base body adopt a fixed position clamping structure, which cannot adjust the installation spacing according to the size specifications of different models of temperature and humidity sensing elements, resulting in poor versatility.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easy-to-install humidity sensor includes: a guide rail and a humidity sensor body. Two sets of guide rail blocks are slidably mounted on the outer surface of the guide rail. Locking rings are fixedly mounted on the upper surface of each set of guide rail blocks. The humidity sensor body can be inserted into the two sets of locking rings and pressed into them by a clamping mechanism. The clamping mechanism is slidably mounted in a connecting cylinder. The connecting cylinder is connected to the upper end of the outer surface of the locking ring.

[0008] Preferably, a first universal ball is fixedly installed at one end of the lower surface of the guide rail rod, a sleeve is rotatably installed on the outer surface of the first universal ball, the other end of the sleeve is rotatably installed on the outer surface of a second universal ball, and an L-shaped clamp is fixedly installed at the other end of the outer surface of the second universal ball.

[0009] Preferably, a transmission plate is slidably mounted on the other end of the L-shaped clamp in a relative manner. The transmission plate is threaded through the threaded part of the threaded rod, while the rod post of the threaded rod is rotatably mounted in the L-shaped clamp and the screw head is turned out from one end.

[0010] Preferably, both ends of the outer surface of the sleeve are rotatably mounted with wing bolts, which can be threaded into the sleeve and press against the outer surfaces of the first and second universal balls to lock them in place.

[0011] Preferably, the clamping mechanism includes a pull cylinder, which is slidably installed inside the connecting cylinder. An arc pressure plate is fixedly installed on the lower surface of the pull cylinder and is embedded in the upper end of the inner ring surface of the locking ring. A pull ring is rotatably installed on the upper surface of the pull cylinder.

[0012] Preferably, a top pressure plate is slidably installed at the upper end of the pull tube. The top pressure plate slides out from both ends of the pull tube and is fixedly installed in the connecting tube. A spring is fixedly connected to the lower surface of the top pressure plate, and the other end of the spring is fixedly connected to the lower surface of the pull tube, so that the spring can apply a downward spring force to the pull tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This humidity sensor requires no special tools during use. Operators can directly drive the transmission plate and L-shaped clamp to clamp the carrier to be installed by rotating the threaded rod, quickly and securely fixing the base. After loosening the wing bolts, the first and second universal ball joints can freely adjust the angle of the guide rail rod. Tightening the bolts fixes the angle to meet the needs of different monitoring directions. The guide rail block can slide along the guide rail rod with damping, easily adjusting the locking ring spacing to accommodate humidity sensor bodies of different lengths. Pulling the pull ring upwards moves the pull cylinder upwards, causing the arc pressure plate to disengage from the locking ring. After placing the sensor, releasing the pull ring causes the spring to push the pull cylinder downwards, allowing the arc pressure plate to automatically press the sensor and complete the fixation. The entire process is simple and intuitive, significantly shortening installation and maintenance time, effectively improving work efficiency, and adapting to various installation scenarios, balancing stability and versatility.

[0019] 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.

[0020] Please see Figures 1-3 This embodiment provides the following technical solution:

[0021] like Figures 1-2As shown, an easy-to-install humidity sensor includes: a guide rail rod 2 and a humidity sensor body 1. Two sets of guide rail blocks 201 are damped and slidably mounted on the outer surface of the guide rail rod 2. Locking rings 202 are fixedly mounted on the upper surface of both sets of guide rail blocks 201. The humidity sensor body 1 can be inserted into the two sets of locking rings 202 and pressed into them by a clamping mechanism 3. The clamping mechanism 3 is slidably mounted in a connecting cylinder 210. The connecting cylinder 210 is connected to the upper end of the outer surface of the locking rings 202.

[0022] The guide rail rod 2 has a first universal ball 204 fixedly installed at one end of its lower surface. A sleeve 203 is rotatably installed on the outer surface of the first universal ball 204. The other end of the sleeve 203 is rotatably installed on the outer surface of the second universal ball 209. An L-shaped clamp 205 is fixedly installed at the other end of the outer surface of the second universal ball 209. A transmission plate 206 is slidably installed at the other end of the L-shaped clamp 205. The transmission plate 206 is threaded through the threaded part of the threaded rod 207, while the rod post of the threaded rod 207 is rotatably installed in the L-shaped clamp 205 with the screw head protruding from one end. Both ends of the outer surface of the sleeve 203 are rotatably installed with wing bolts 208. The wing bolts 208 can be threadedly tightened into the sleeve 203 and press against the outer surfaces of the first universal ball 204 and the second universal ball 209 respectively to lock them.

[0023] Through the design of the humidity sensor body 1, guide rail rod 2, guide rail block 201, locking ring 202, sleeve 203, first universal ball joint 204, L-shaped clamping plate 205, transmission plate 206, threaded rod 207, and clamping mechanism 3, in actual use, the operator can attach one side of the L-shaped clamping plate 205 to a suitable position on the carrier to be installed, such as the edge of a cabinet or equipment bracket, and then rotate the threaded head of the threaded rod 207. Since the rod post of the threaded rod 207 is rotatably installed inside the L-shaped clamping plate 205, and its threaded part is threadedly connected to the transmission plate 206 which is slidably installed inside the L-shaped clamping plate 205, as the threaded rod 207 rotates, the transmission... Plate 206 will slide relative to the inner side of L-shaped clamp 205 until the transmission plate 206 and the other side of L-shaped clamp 205 clamp the carrier to be installed, thereby achieving a stable fixation of the entire sensor mounting base. Then, adjust the angle of guide rail rod 2 according to actual monitoring needs. At this time, the wing bolts 208 at both ends of the outer surface of sleeve 203 can be loosened. Since both ends of sleeve 203 are rotatably connected to guide rail rod 2 and L-shaped clamp 205 through first universal ball 204 and second universal ball 209 respectively, after loosening the wing bolts 208, the first universal ball 204 and second universal ball 209 can rotate freely inside sleeve 203, thereby driving the guide rail rod. 2. Adjust to the required tilt angle or horizontal position. After the angle adjustment is complete, retighten the wing bolts 208 at both ends so that the ends of the wing bolts 208 press against the outer surfaces of the first universal ball 204 and the second universal ball 209, locking their rotational freedom and ensuring that the guide rail rod 2 remains at the set angle. Then, the distance between the two sets of guide rail blocks 201 can be adjusted according to the length of the humidity sensor body 1. Since the guide rail blocks 201 are damped and slidably installed on the outer surface of the guide rail rod 2, the operator can directly push the two sets of guide rail blocks 201 to slide along the guide rail rod 2. The damping structure allows the guide rail blocks 201 to stop and remain in place at any time during the sliding process. At the current position, until the distance between the locking rings 202 on the two sets of guide rail blocks 201 matches the length of the humidity sensor body 1, both ends of the humidity sensor body 1 can be inserted into the two sets of locking rings 202 respectively. Then, by operating the clamping mechanism 3, the clamping mechanism 3 slides in the connecting cylinder 210 and applies pressure to the humidity sensor body 1 in the locking ring 202, clamping and fixing it in the locking ring 202, thus completing the entire humidity sensor installation process. If the sensor needs to be disassembled or adjusted later, simply reverse the operation of the clamping mechanism 3 to release the fixation, and then adjust the distance between the guide rail blocks 201, the angle of the guide rail rod 2, or loosen the L-shaped clamp 205 as needed.

[0024] like Figure 3As shown, the clamping mechanism 3 includes a pull cylinder 301, which is slidably installed inside the connecting cylinder 210. An arc pressure plate 305 is fixedly installed on the lower surface of the pull cylinder 301 and is embedded in the upper end of the inner ring surface of the locking ring 202. A pull ring 303 is rotatably installed on the upper surface of the pull cylinder 301. A top pressure plate 302 is slidably installed at the upper end of the pull cylinder 301. The top pressure plate 302 slides out from both ends of the pull cylinder 301 and is fixedly installed inside the connecting cylinder 210. A spring 304 is fixedly connected to the lower surface of the top pressure plate 302. The other end of the spring 304 is fixedly connected to the lower surface of the pull cylinder 301, so that the spring 304 can apply a downward spring force to the pull cylinder 301.

[0025] Through the design of the pull cylinder 301, top pressure plate 302, pull ring 303, spring 304, and arc pressure plate 305, when installing the humidity sensor body 1, the operator can pull the pull ring 303 upwards. Since the pull ring 303 is rotatably mounted on the upper surface of the pull cylinder 301, pulling the pull ring 303 will cause the pull cylinder 301 to slide upwards within the connecting cylinder 210. At this time, the spring 304 between the lower inner surface of the pull cylinder 301 and the lower surface of the top pressure plate 302 will be compressed. The top pressure plate 302, having slid out from both ends of the pull cylinder 301 and fixed within the connecting cylinder 210, will... While remaining stationary, as the pull cylinder 301 moves upward, the arc-shaped pressure plate 305 fixed on its lower surface moves upward synchronously from its embedded position at the upper end of the inner ring surface of the locking ring 202, creating sufficient space inside the locking ring 202 for the humidity sensor body 1 to pass through. After the humidity sensor body 1 is inserted into the locking ring 202, the pull ring 303 is released, and the compressed spring 304 generates a downward restoring force, which in turn pushes the pull cylinder 301 downward within the connecting cylinder 210. The pull cylinder 301 then drives the arc-shaped pressure plate 305 downward and presses it tightly against the outside of the humidity sensor body 1. The surface of the clamping mechanism 302 securely fastens the humidity sensor body 1. During this process, the rotating design of the pull ring 303 allows the operator to apply force from different angles, improving operational convenience. The continuous spring force provided by the spring 304 ensures that the arc pressure plate 305 maintains pressure on the humidity sensor body 1 at all times. Even in environments with slight equipment vibration or airflow impact, it can prevent the humidity sensor body 1 from loosening or shifting, ensuring the stability of the fixation. At the same time, the arc-shaped structure of the arc pressure plate 305 can better fit with the outer surface of the humidity sensor body 1, increasing the contact area, which not only improves the fixation effect but also avoids damage to the humidity sensor body 1 caused by excessive local pressure. The top pressure plate 302 provides stable force support for the spring 304, ensuring that the spring force of the spring 304 can accurately act on the pull cylinder 301. The operation of the entire clamping mechanism 3 can be completed simply by pulling and releasing the pull ring 303 without the need for tools, further enhancing the convenience of the entire humidity sensor installation, lowering the operation threshold, and also providing convenience for subsequent disassembly and replacement of the humidity sensor body 1, reducing maintenance time and costs.

[0026] The humidity sensor body 1 can be any of the Sensirion brand, model SHT45-AD1F or SHT40I-HD1B.

[0027] Based on the above technical solution, the working steps of this solution are summarized as follows: During use, the operator can attach one side of the L-shaped clamp 205 to the carrier to be installed, such as the edge of a cabinet, equipment bracket, etc., at a suitable position. Then, rotate the threaded head of the threaded rod 207. Since the rod post of the threaded rod 207 is rotatably installed inside the L-shaped clamp 205, and its threaded part is threadedly connected to the transmission plate 206 that slides inside the L-shaped clamp 205, as the threaded rod 207 rotates, the transmission plate 206 will slide relative to the inner side of the L-shaped clamp 205 until the transmission plate 206 and the other side of the L-shaped clamp 205 together clamp the carrier to be installed, thereby achieving a stable fixation of the entire sensor mounting base. Then, adjust the guide rail rod 2 according to the actual monitoring requirements. At this angle, the wing bolts 208 at both ends of the outer surface of the sleeve 203 can be loosened. Since both ends of the sleeve 203 are rotatably connected to the guide rail rod 2 and the L-shaped clamp 205 via the first universal ball 204 and the second universal ball 209 respectively, loosening the wing bolts 208 allows the first universal ball 204 and the second universal ball 209 to rotate freely within the sleeve 203, thereby adjusting the guide rail rod 2 to the required tilt angle or horizontal position. After the angle adjustment is complete, retighten the wing bolts 208 at both ends, so that the ends of the wing bolts 208 press against the outer surfaces of the first universal ball 204 and the second universal ball 209, locking their rotational freedom and ensuring that the guide rail rod 2 remains at the set angle. Then, according to the humidity sensor body 1... The distance between the two sets of guide rail blocks 201 is adjusted. Since the guide rail blocks 201 are damped and slidably mounted on the outer surface of the guide rail rod 2, the operator can directly push the two sets of guide rail blocks 201 to slide along the guide rail rod 2. The damping structure allows the guide rail blocks 201 to stop at any time during the sliding process and maintain the current position until the distance between the locking rings 202 on the two sets of guide rail blocks 201 matches the length of the humidity sensor body 1. Then, the pull ring 303 can be pulled upward. Since the pull ring 303 is rotatably mounted on the upper surface of the pull cylinder 301, pulling the pull ring 303 will drive the pull cylinder 301 to slide upward in the connecting cylinder 210. At this time, the spring 304 between the lower inner surface of the pull cylinder 301 and the lower surface of the top pressure plate 302 will be compressed. The top pressure plate 302 will be compressed due to the pull cylinder 301. Both ends slide out and are fixed inside the connecting cylinder 210 and remain stationary. As the pull cylinder 301 moves upward, the arc pressure plate 305 fixed on its lower surface moves upward synchronously from the embedded position at the upper end of the inner ring surface of the locking ring 202, so that the inside of the locking ring 202 forms enough space for the humidity sensor body 1 to pass through. After the humidity sensor body 1 is placed into the locking ring 202, the pull ring 303 is released. The compressed spring 304 will generate a downward reset spring force, which will push the pull cylinder 301 to slide downward inside the connecting cylinder 210. The pull cylinder 301 will then drive the arc pressure plate 305 to move downward and press tightly against the outer surface of the humidity sensor body 1, so as to achieve a stable clamping and fixing of the humidity sensor body 1. The operation of the entire clamping mechanism 3 can be completed by simply pulling and releasing the pull ring 303.

[0028] In summary: The L-shaped clamping plate 205, threaded rod 207, and transmission plate 206 work together to quickly clamp and fix different carriers such as cabinet edges and equipment brackets without drilling or relying on smooth surfaces, making it highly adaptable to various installation scenarios. Furthermore, the combination of the first universal ball joint 204, the second universal ball joint 209, the sleeve 203, and the wing bolt 208 allows the guide rail rod 2 angle to be flexibly adjusted and securely locked, meeting diverse monitoring direction requirements. The damping guide rail block 201 allows the spacing of the locking ring 202 to be freely adjusted according to the length of the humidity sensor body 1, improving the versatility of the device. The clamping mechanism 3, through the linkage of the pull ring 303, pull cylinder 301, spring 304, and arc pressure plate 305, allows the fixation and disassembly of the humidity sensor body 1 to be completed with simple pulling and releasing actions, without the need for tools. This achieves convenient assembly and disassembly, significantly reducing installation and maintenance time costs and effectively improving work efficiency.
