[0001] The utility model relates to the technical field of nitrogen concentration detection sensors, in particular to a mounting bracket and a nitrogen concentration detection sensor. Background Technique

[0002] A mounting bracket is a device for placing a nitrogen concentration detection sensor. When using the nitrogen concentration detection sensor, the sensor body is directly arranged inside the mounting bracket, and then the sensor is arranged in the industrial experiment room. The gas is sucked into the sensor body through an air pump, and the nitrogen concentration is detected inside the sensor and then displayed on the display screen, so that the nitrogen content in the industrial experiment environment can be understood.

[0003] The inventor found in daily work that the nitrogen concentration detection sensor still has at least the following problems: when using the nitrogen concentration detection sensor, the sensor body is directly arranged inside the mounting bracket, and then the sensor is arranged in the industrial experiment room. The gas is sucked into the sensor body through an air pump, and the nitrogen concentration is detected inside the sensor and then displayed on the display screen, so that the nitrogen content in the industrial experiment environment can be understood. However, in the actual use process, the sensor body is mostly directly clamped on the fixing plate through an elastic component. Because the sensor needs to be regularly overhauled, multiple disassembly will cause wear of the elastic component, which will affect the fixing of the sensor to a certain extent. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a mounting bracket and a nitrogen concentration detection sensor are proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a mounting bracket and a nitrogen concentration detection sensor, including a fixing plate, a limiting device is arranged on one side of the fixing plate, a protection device is arranged at the bottom of the fixing plate, the limiting device includes a support plate, the support plate is fixedly connected with one side of the fixing plate, a chute is arranged on one side of the fixing plate, a clamping strip is slidably connected to the inner wall of the chute, a first spring is fixedly connected to one side of the inner wall of the chute, and one end of the first spring close to the chute is fixedly connected to one side of the clamping strip.

[0006] The effects achieved by the above components are as follows: when using the limiting device, manually place the sensor on the top of the support plate, and then manually control the clamping strip to slide inside the chute. The first spring squeezes the clamping strip towards the middle of the fixing plate in the chute, so that the clamping strip can be well restricted on one side of the sensor, and thus the sensor can be well arranged on one side of the fixing plate.

[0012] The effects achieved by the above components are as follows: Slide the pressing plate to the top of the sensor, and then squeeze the pressing plate towards the limiting groove by the third spring, so that the pressing plate can be well arranged on the top of the sensor.

[0013] Preferably, the protection device includes a baffle. Connecting rods are uniformly and fixedly connected to the bottom of the support plate, and the bottom of the connecting rods is fixedly connected to the baffle.

[0014] The effects achieved by the above components are as follows: When using the protection device, set the connecting rods and the baffle at the bottom of the sensor, which can, to a certain extent, prevent sundries from blocking the air inlet of the sensor and affecting the operation of the sensor.

[0028] Refer to Figure 2, the limiting device 5 includes a support plate 504. The support plate 504 is fixedly connected to one side of the fixed plate 1. A sliding groove 501 is formed on one side of the fixed plate 1. A clamping strip 502 is slidably connected to the inner wall of the sliding groove 501. A first spring 503 is fixedly connected to one side of the inner wall of the sliding groove 501. One end of the first spring 503 close to the sliding groove 501 is fixedly connected to one side of the clamping strip 502. When using the limiting device 5, manually place the sensor on the top of the support plate 504, and then manually control the clamping strip 502 to slide inside the sliding groove 501. The first spring 503 squeezes the clamping strip 502 towards the middle of the fixed plate 1 in the sliding groove 501, thereby well restricting the clamping strip 502 on one side of the sensor. In this way, the sensor can be well arranged on one side of the fixed plate 1. A receiving groove 505 is formed on one side of the clamping strip 502. A round rod 506 is fixedly connected to the inner wall of the receiving groove 505. A rotating strip 507 is rotatably sleeved on the surface of the round rod 506. One end of the rotating strip 507 is slidably inserted with a clamping block 508. The clamping block 508 is arranged on one side of another clamping strip 502. Manually control the rotating strip 507 to rotate on the surface of the round rod 506, and then slide the rotating strip 507 into the receiving groove 505. Then insert the clamping block 508 into one side of the rotating strip 507, thereby arranging the clamping block 508 on one side of the clamping strip 502. In this way, the clamping strip 502 can be well arranged on one side of the sensor. A damping rod 509 is fixedly connected to one side of the clamping block 508. One end of the damping rod 509 close to the clamping block 508 is fixedly connected to one side of the rotating strip 507. A second spring 510 is sleeved on the surface of the damping rod 509. One end of the second spring 510 is fixedly connected to one side of the clamping block 508. One end of the second spring 510 close to the damping rod 509 is fixedly connected to one side of the rotating strip 507. A connecting frame 511 is slidably sleeved on the surface of the clamping block 508. The connecting frame 511 is fixedly connected to one side of the clamping strip 502. By pulling the clamping block 508 towards the rotating strip 507 by the second spring 510, the clamping block 508 is well restricted inside the connecting frame 511. In this way, the clamping block 508 can be well arranged on one side of the clamping strip 502. A limiting groove 512 is formed on one side of the fixed plate 1. An extrusion plate 513 is slidably connected to the inner wall of the limiting groove 512. A third spring 514 is fixedly connected to the top of the inner wall of the limiting groove 512. One end of the third spring 514 close to the limiting groove 512 is fixedly connected to the top of the extrusion plate 513. Slide the extrusion plate 513 to the top of the sensor, and then squeeze the extrusion plate 513 towards the limiting groove 512 by the third spring 514, thereby the extrusion plate 513 can be well arranged on the top of the sensor.

[0029] Refer to Figure 3 and Figure 4, the protection device 6 includes a baffle 601. The bottom of the support plate 504 is uniformly and fixedly connected with connecting rods 602, and the bottom of the connecting rods 602 is fixedly connected with the baffle 601. When using the protection device 6, the connecting rods 602 and the baffle 601 are arranged at the bottom of the sensor, which can, to a certain extent, prevent sundries from blocking the air inlet of the sensor and affecting the operation of the sensor. The bottom of the support plate 504 is fixedly connected with a support bar 605. A first rotating rod 606 is rotatably inserted through one side of the support bar 605. A semi-circular plate 607 is uniformly fixedly connected to one side of the first rotating rod 606. A first bevel gear 608 is fixedly connected to the end of the first rotating rod 606 away from the semi-circular plate 607. When the air flow impacts the semi-circular plate 607 when the air enters the sensor, it can drive the first bevel gear 608 to rotate. A second rotating rod 609 is rotatably inserted through the top of the baffle 601. A second bevel gear 610 is fixedly connected to the top of the second rotating rod 609. The second bevel gear 610 meshes with the first bevel gear 608. A first pulley 611 is fixedly connected to the surface of the second rotating rod 609. A connecting belt 613 is sleeved on the surface of the first pulley 611. A second pulley 612 is sleeved on the inner wall of the connecting belt 613. A limiting rod 603 is fixedly connected to the bottom of the second pulley 612. The limiting rod 603 is rotatably inserted through the top of the baffle 601. An L-shaped rod 604 is fixedly connected to one side of the limiting rod 603. Since the first bevel gear 608 and the second bevel gear 610 mesh with each other, the first bevel gear 608 can drive the second bevel gear 610 to rotate, and then drive the L-shaped rod 604 to rotate on the surfaces of the baffle 601 and the connecting rod 602 through the connecting belt 613, which can, to a certain extent, scrape the sundries off the surfaces of the baffle 601 and the connecting rod 602.

[0030] Working principle: When using the nitrogen concentration detection sensor, directly place the sensor body 2 inside the mounting bracket, and then place the sensor in the industrial experiment room. Use the air pump 3 to suck the gas into the sensor body 2, detect the nitrogen concentration inside the sensor, and then display it on the display screen, so as to understand the nitrogen content in the industrial experiment environment. When using the limiting device 5, manually place the sensor on the top of the support plate 504, and then manually control the sliding of the clamping strip 502 inside the sliding groove 501. Squeeze the clamping strip 502 towards the direction of the middle of the fixed plate 1 in the sliding groove 501 through the first spring 503, so as to well limit the clamping strip 502 on one side of the sensor. Then manually control the rotation of the rotating bar 507 on the surface of the round rod 506, and then slide the rotating bar 507 into the receiving groove 505. Then insert the clamping block 508 into one side of the rotating bar 507, and pull the clamping block 508 towards the direction of the rotating bar 507 through the second spring 510, so as to well limit the clamping block 508 inside the connecting frame 511. In this way, the clamping block 508 can be well set on one side of the clamping strip 502, and the clamping strip 502 can be well set on one side of the sensor. Slide the pressing plate 513 to the top of the sensor, and then squeeze the pressing plate 513 towards the direction of the limiting groove 512 through the third spring 514, so as to well set the pressing plate 513 on the top of the sensor. In this way, the sensor can be well set on one side of the fixed plate 1. When using the protection device 6, set the connecting rod 602 and the baffle 601 at the bottom of the sensor, which can, to a certain extent, prevent sundries from blocking the air inlet of the sensor. When the air enters the sensor and the air flow impacts the semi-circular plate 607, it can well drive the first bevel gear 608 to rotate. Because the first bevel gear 608 and the second bevel gear 610 are meshed with each other, the first bevel gear 608 can well drive the second bevel gear 610 to rotate, and then drive the L-shaped rod 604 to rotate on the surfaces of the baffle 601 and the connecting rod 602 through the connecting belt 613. In this way, the sundries can be scraped off the surfaces of the baffle 601 and the connecting rod 602 to a certain extent, which can, to a certain extent, prevent the work of the sensor from being affected.
