Description

Technical Field

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

[0002] A carbon dioxide sensor is a device that can detect the concentration of carbon dioxide in the environment. It has a wide range of applications in many fields such as industrial production, agricultural planting, and indoor air quality monitoring, and is of great significance for protecting the production and living environment in various fields.

[0003] Existing carbon dioxide sensors are mostly installed using bolt-fixed or snap-fit ​​structures. These methods require tools and involve multiple steps during installation and disassembly, resulting in low installation efficiency. This is especially inconvenient in situations requiring frequent maintenance, replacement, or calibration (such as laboratories and industrial production lines). Furthermore, traditional installation structures often lack multi-directional limiting designs, making the sensor prone to displacement due to vibration or external forces during long-term use, affecting measurement accuracy and even posing a risk of detachment. Utility Model Content

[0004] The purpose of this invention is to provide a carbon dioxide sensor that is easy to install, which solves the problems mentioned in the background art that the existing carbon dioxide sensors are cumbersome to disassemble and assemble and lack multi-directional limiting design.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carbon dioxide sensor that is easy to install, comprising a sensor body and a mounting base. A first pressing groove is formed at the center of the top of the mounting base. A first pressing block is vertically slidably connected to the inner side of the first pressing groove. An I-shaped block is fixedly connected to the bottom of the first pressing block, and the I-shaped block contacts one end of an insertion rod. A second pressing groove is formed on the inner side of the mounting base on one side of the first pressing block. A horizontal plate is vertically slidably connected to the inner side of the second pressing groove. A second pressing block and a limiting rod are fixedly connected to the top two sides of the horizontal plate, respectively.

[0006] In this technical solution, during the pressing process, the sensor body first contacts the first pressing block, causing the I-shaped block below to descend and lose contact with the insertion rod, thus allowing the side clamping block to limit the sensor body from the side. As the pressing continues, it continues to squeeze the second pressing block, causing the limiting rod to lose its constraint on the front baffle, causing the front baffle to slide down, thereby blocking the front of the sensor body and preventing it from falling. The two work together to improve stability, and the solution is easy to assemble and disassemble, making it highly practical.

[0007] Preferably, a rubber ring is fixedly connected to the surface of the mounting base directly below the first pressing block, an air inlet groove is provided on the surface of the mounting base inside the rubber ring, a torsion groove is provided in the center of the bottom of the mounting base, the torsion groove is connected to the air inlet groove, and a torsion block is rotatably connected to the inside of the torsion groove.

[0008] In this technical solution, after the torsion block rotates, the air inlet slot is connected to the outside, and air enters the rubber ring, losing the suction cup effect. At this time, the sensor body can be removed. This adds an extra layer of protection and further improves the stability of the sensor body on the mounting surface.

[0009] Preferably, the left and right inner sidewalls of the mounting base are provided with lifting grooves, and a front baffle is slidably connected to the inner side of the lifting groove. Limiting holes are provided at the lower ends of the left and right sides of the surface of the front baffle.

[0010] In this technical solution, a limiting rod is inserted into the limiting hole. At this time, the front baffle remains stationary. After the second pressing block is pressed to be flush with the surface of the mounting base, the limiting rod will completely disengage from the limiting hole, and the front baffle will slide down smoothly to complete the front obstruction of the sensor body.

[0011] Preferably, a telescopic groove is provided between the second pressing groove and the lifting groove, and the two ends of the telescopic groove are respectively connected to the second pressing groove and the lifting groove, and the limiting rod is located inside the telescopic groove.

[0012] In this technical solution, the limiting rod slides inside the telescopic groove, which on the one hand blocks the front baffle, and on the other hand improves the stability of the horizontal plate during the up and down movement.

[0013] Preferably, the mounting base surfaces on both sides of the first pressing groove are provided with adjustment grooves, and clamping blocks are slidably connected to the surface of the adjustment grooves. Insert rods are fixedly connected to the side walls of the clamping blocks, and the far end of the insert rods passes through the adjustment grooves and contacts the I-shaped block.

[0014] In this technical solution, the I-shaped block can normally hold the insert rod, and when it is squeezed, it descends, and the two insert blocks will insert into the waist position of the I-shaped block, causing the clamping blocks on the left and right sides to move towards the center to complete the clamping.

[0015] Preferably, a first spring is fixedly connected between the front baffle and the inner bottom of the lifting groove, a second spring is fixedly connected between the I-shaped block and the inner bottom of the first pressing groove, a third spring is fixedly connected between the clamping block and the inner side wall of the adjusting groove, and a fourth spring is fixedly connected between the bottom of the horizontal plate and the inner bottom of the second pressing groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model installs the sensor body by setting a mounting base. The sensor body is directly pressed onto the surface of the mounting base. The first pressing block is squeezed, and the I-shaped block loses its limit on the insertion rod, so that the clamping blocks on both sides clamp the central sensor body. This process does not require auxiliary tools or complicated operations, which significantly improves the efficiency of disassembly and assembly, and is especially suitable for industrial and scientific research scenarios that require high-frequency maintenance.

[0018] 2. After limiting the left and right directions of the sensor body, the sensor body can continue to be pressed down. The second pressing block is squeezed. When it is squeezed to be flush with the surface of the mounting base, the limiting rod loses its constraint on the front baffle. The front baffle falls down and blocks the front side of the sensor body, thus completing the limiting installation. This double limiting structure effectively avoids the displacement or falling off of the sensor due to vibration or external force, greatly improves the installation stability, and maintains the convenience of "one-click installation". It has both high reliability and easy operation. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0028] An easy-to-install carbon dioxide sensor, see [link / reference] Figures 1 to 6 The device includes a sensor body 1 and a mounting base 101. A pressing groove 601 is formed at the center of the top of the mounting base 101. A pressing block 6 is vertically slidably connected to the inner side of the pressing groove 601. An I-shaped block 602 is fixedly connected to the bottom of the pressing block 6. The I-shaped block 602 contacts one end of the insertion rod 7. When the sensor body 1 is installed, it is pressed directly onto the surface of the mounting base 101. At this time, the pressing block 6 is squeezed. The pressing block 6 drives the I-shaped block 602 to move downward until it loses its constraint on the insertion rod 7. The insertion rod 7 is inserted into the waist position of the I-shaped block 602, thereby completing the adjustment of the position of the clamping block 701.

[0029] Meanwhile, adjustment grooves 702 are provided on the surfaces of the mounting bases 101 on both sides of the first pressing groove 601. Clamping blocks 701 are slidably connected to the surface of the adjustment grooves 702. Insert rods 7 are fixedly connected to the side walls of the clamping blocks 701. The far end of the insert rods 7 passes through the adjustment grooves 702 and contacts the I-shaped block 602. A second spring 603 is fixedly connected between the I-shaped block 602 and the inner bottom of the first pressing groove 601. A third spring 703 is fixedly connected between the clamping blocks 701 and the inner side walls of the adjustment grooves 702. The insert rods 7 are inserted into the waist groove of the I-shaped block 602 under the push of the third spring 703. At this time, the clamping blocks 701 move towards the center of the mounting base 101, thereby clamping the sensor body 1 from both sides and fixing it in the left and right directions. The whole process does not require any additional fixing mechanisms, which is convenient and quick.

[0030] Specifically, such as Figure 6 As shown, a second pressing groove 901 is provided on the inner side of the mounting base 101 on one side of the first pressing block 6. A horizontal plate 9 is vertically slidably connected to the inner side of the second pressing groove 901. The second pressing block 8 and the limiting rod 10 are fixedly connected to the top two sides of the horizontal plate 9, respectively. A telescopic groove 902 is provided between the second pressing groove 901 and the lifting groove 202. The two ends of the telescopic groove 902 are connected to the second pressing groove 901 and the lifting groove 202, respectively. The limiting rod 10 is located inside the telescopic groove 902. The bottom of the horizontal plate 9 is connected to the second pressing block 8. A fourth spring 903 is fixedly connected between the inner bottom of the groove 901. After being limited in the left and right directions, the sensor body 1 still has the ability to move back and forth. Therefore, if it continues to press down, the second pressing block 8 will be squeezed. When it is squeezed to be flush with the surface of the mounting base 101, the limiting rod 10 in the telescopic groove 902 will completely retract. After the front baffle 2 loses its limit, it will fall down and block the front side of the sensor body 1, thus completing the limitation in the front and back directions. The installation process is quick and convenient, and it is highly practical.

[0031] Furthermore, such as Figure 2 and Figure 4 As shown, the left and right inner walls of the mounting base 101 are provided with lifting grooves 202. A front baffle 2 is slidably connected to the inner side of the lifting groove 202. Limiting holes 201 are provided on the lower ends of the left and right sides of the surface of the front baffle 2. A first spring 203 is fixedly connected between the front baffle 2 and the inner bottom of the lifting groove 202. The limiting rod 10 is normally inserted in the limiting hole 201 to limit the front baffle 2. After the limiting rod 10 is retracted, the front baffle 2 will fall under the pull of the first spring 203, thereby blocking the left and right edges of the front of the sensor body 1 and completing the front-back direction limitation.

[0032] It is worth noting that, such as Figure 3 As shown, a rubber ring 3 is fixedly connected to the surface of the mounting base 101 directly below the first pressing block 6. An air inlet groove 4 is opened on the surface of the mounting base 101 inside the rubber ring 3. A torsion groove 5 is opened in the center of the bottom of the mounting base 101. The torsion groove 5 communicates with the air inlet groove 4. A torsion block 501 is rotatably connected to the inside of the torsion groove 5. The rubber ring 3 is flared. During the pressing of the sensor, it will stick tightly to the back of the sensor body 1 and force out the air, which acts as a suction cup. This provides installation security for the sensor body 1 and prevents it from falling off suddenly during disassembly. When the suction cup effect is needed, simply rotate the torsion block 501 so that the notch on the torsion block 501 reaches the air inlet groove 4. At this time, air enters and the sensor body 1 can be removed. It should be noted that a sealing ring is provided on the side of the torsion block 501 facing the air inlet groove 4 to ensure that there is no air leakage. In addition, the rotation of the torsion block 501 has a large friction to prevent it from rotating freely.

[0033] The sensor body 1 can be a carbon dioxide sensor based on the principle of infrared absorption, which internally includes an infrared light source, a measuring chamber, an infrared detector, and a signal processing circuit. The infrared light source emits infrared light of a specific wavelength. When carbon dioxide gas enters the measuring chamber, it absorbs the infrared light of that specific wavelength, causing the light intensity to attenuate. The infrared detector measures the intensity of the transmitted or reflected light and converts the light intensity signal into an electrical signal. The signal processing circuit processes the electrical signal and finally outputs the concentration value of carbon dioxide. This method of measuring gas concentration by utilizing the absorption characteristics of carbon dioxide to infrared light of a specific wavelength has high accuracy and stability.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0035] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
