An infrared oil analyzer with a sealed structure

Abstract

This utility model relates to the field of infrared oil analyzer technology and discloses an infrared oil analyzer with a sealed structure, including an infrared oil analyzer body and a housing. The infrared oil analyzer body is placed inside the housing. Through a protective component, when the operator rotates the rocker arm to rotate the screw, the clamping plate clamps and fixes the oil analyzer body. With continued rotation, the insertion rod inserts into the insertion hole and contacts the inner wall of the contact groove, thereby driving the slider to move towards the limiting groove, causing the limiting block to enter the limiting groove. When the limiting block contacts the inner wall of the limiting groove, the movable plate is locked and cannot move further, the clamping plate also stops clamping, and the screw and rocker arm are simultaneously locked. This prevents over-clamping caused by the operator not stopping the force in time, avoids deformation of the oil analyzer body due to excessive clamping force, and ensures normal use and measurement accuracy of the instrument.

Description

Technical Field

[0001] This utility model relates to the field of infrared oil analyzer technology, specifically to an infrared oil analyzer with a sealed structure. Background Technology

[0002] An infrared oil analyzer is a detection instrument primarily used for monitoring water quality and hazardous waste sites, as well as for monitoring oil and water separation processes, among other applications.

[0003] According to a public notice of an infrared oil meter with a sealing mechanism (publication number: CN216685440U), in the above application, pulling the clamping plate to the left compresses the second compression spring, and the second compression spring generates a reaction force to clamp the infrared oil meter, thereby making it easier to fix the infrared oil meter.

[0004] In the aforementioned application, the clamping force relies solely on the elasticity of the spring, which has limited fixing strength. When the equipment is subjected to vibration or external force, the infrared oil meter may loosen or even fall off, affecting the accuracy of the detection and the safety of the instrument. If other rigid clamps are used to replace the spring clamping, if the operator fails to stop applying force in time during the clamping process, the clamping force will be too large, causing deformation of the infrared oil meter's outer shell or internal structure, thereby affecting the normal use of the instrument and the measurement accuracy. Utility Model Content

[0005] The purpose of this invention is to provide an infrared oil meter with a sealed structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an infrared oil meter with a sealed structure, comprising an infrared oil meter body and a housing, wherein the infrared oil meter body is placed inside the housing, and the housing is provided with fixing components and protective components.

[0007] The protective components include:

[0008] The limiting groove is used to cooperate with the limiting block for limiting;

[0009] Slide groove one is used to stabilize the slider;

[0010] The contact groove is used to cooperate with the insertion rod to drive the slider to move.

[0011] Preferably, the fixing assembly includes a rocker arm rotatably connected to the left side of the housing. A groove is formed at the bottom of the housing, and the output shaft of the rocker arm passes through this groove. A screw is rotatably connected to the inner wall of the groove, and the left end of the screw is fixedly connected to the surface of the output shaft of the rocker arm. A movable plate is slidably connected to the inner wall of the groove, and the screw passes through the movable plate and is threadedly connected to it. A movable plate is fixed to the top of the movable plate, and the movable plate is slidably connected to the bottom of the inner wall of the housing. A clamping plate is slidably connected to the bottom of the inner wall of the housing. A fixed plate is fixed to the bottom of the wall. A sliding rod is fixed to the side of the clamping plate away from the center of the box. The end of the sliding rod away from the clamping plate passes through the fixed plate and is slidably connected to the fixed plate. A spring is fixed to the surface of the end of the sliding rod away from the fixed plate. The end of the spring away from the sliding rod is fixed to the side of the fixed plate away from the clamping plate. Rotating the rocker arm forward causes the screw to move the moving plate and the movable plate synchronously. The surface of the movable plate abuts against the surface of the sliding rod, causing the clamping plate to move closer to the infrared oil meter body, thus clamping and fixing the clamping plate to the infrared oil meter body. Reversing the rocker arm releases the clamping plate.

[0012] Preferably, the limiting groove is formed on the inner wall of the housing, and the movable plate has sliding grooves on both sides. A slider is slidably connected to the inner wall of the sliding groove, and a spring is fixed to the outer surface of the slider. The end of the spring away from the slider is fixed to the inner wall of the sliding groove. The end of the slider away from the spring has a sliding groove. A limiting block is slidably connected to the inner wall of the sliding groove. A spring is fixed to the outer surface of the limiting block. The end of the spring away from the limiting block is fixed to the inner wall of the sliding groove. The outer surface of the slider has a... The contact groove has a fixed rod on the side of the fixed plate away from the clamping plate, and an insertion hole on the side of the movable plate close to the fixed plate. The insertion hole communicates with the sliding groove. The clamping plate clamps and fixes the infrared oil meter body. When the rocker arm is continuously rotated, the insertion rod moves into the insertion hole and abuts against the inner wall of the contact groove. The slider and the limiting block move, and the limiting block enters the limiting groove. At this time, the inner wall of the limiting groove abuts against the side of the limiting block away from the inclined surface, so that the movable plate can no longer move, and the clamping plate can no longer move. At this time, the screw and the rocker arm can no longer rotate.

[0013] Preferably, the rocker arm has a bolt on its surface, the bolt passes through the rocker arm, and the bolt is threadedly connected to the rocker arm, which facilitates limiting the rocker arm's position and prevents accidental contact from affecting stability.

[0014] Preferably, a sealing cap is installed on the outer surface of the infrared oil meter body to facilitate sealing.

[0015] Preferably, the screw is provided with two opposite threads, which can cause the moving plates to move closer or further apart synchronously when rotated.

[0016] Preferably, the abutting groove is set as an inclined surface, and the end of the limiting block away from the spring three is set as an inclined surface. When the inclined surface of the abutting groove is abutted, it can drive the slider and the limiting block to move. When the inclined surface of the limiting block is abutted, the limiting block can move into the sliding groove two.

[0017] Compared with the prior art, this utility model provides an infrared oil meter with a sealed structure, which has the following advantages:

[0018] 1. This infrared oil meter with a sealed structure, through its protective components, clamps and secures the meter body when the operator rotates the rocker arm to drive the screw. With continued rotation, the insertion rod inserts into the insertion hole and contacts the inner wall of the contact groove, thereby moving the slider towards the limiting groove, causing the limiting block to enter the limiting groove. When the limiting block contacts the inner wall of the limiting groove, the movable plate is locked and cannot move further, the clamping plate stops clamping, and the screw and rocker arm are simultaneously locked. This prevents over-clamping due to the operator's failure to stop applying force in time, avoids deformation of the oil meter body due to excessive clamping force, and ensures normal instrument use and measurement accuracy.

[0019] 2. This infrared oil meter with a sealed structure, through the fixed components, rotates the rocker arm and screw to drive the moving plate and movable plate closer together. The surface of the movable plate abuts against the surface of the sliding rod, and the clamping plate moves closer to the infrared oil meter body, so that the clamping plate clamps and fixes the infrared oil meter body, ensuring the stable fixation of the infrared oil meter body. Reversing the rocker arm will release it. Attached Figure Description

[0026] like Figures 1-5 As shown, this utility model provides a technical solution: an infrared oil meter with a sealed structure, including an infrared oil meter body 1 and a housing 2. The infrared oil meter body 1 is placed inside the housing 2. The housing 2 is provided with a fixing component 3 and a protective component 4. The protective component 4 includes: a limiting groove 40, a sliding groove 41, a slider 42, a spring 43, a contact groove 44, a sliding groove 45, a limiting block 46, a spring 47, a plug rod 48, and a plug hole 49.

[0027] The fixing component 3 includes a rocker arm 30, which is rotatably connected to the left side of the housing 2. A groove 31 is provided at the bottom of the housing 2. The output shaft of the rocker arm 30 passes through the groove 31. A screw 32 is rotatably connected to the inner wall of the groove 31. The left end of the screw 32 is fixedly connected to the surface of the output shaft of the rocker arm 30. A movable plate 33 is slidably connected to the inner wall of the groove 31. The screw 32 passes through the movable plate 33 and is threadedly connected to the movable plate 33. A movable plate 34 is fixed to the top of the movable plate 33 and slidably connected to the bottom of the inner wall of the housing 2. A clamping plate 35 is slidably connected to the bottom of the inner wall of the housing 2. A fixing plate 36 is fixed to the bottom of the inner wall of the housing 2. A sliding rod 37 is fixed to the side of the clamping plate 35 away from the center of the housing 2. The sliding rod 37 is located away from the clamping plate 35. One end of the sliding rod 37 passes through the fixed plate 36 and is slidably connected to the fixed plate 36. A spring 38 is fixed to the surface of the end of the sliding rod 37 away from the fixed plate 36. The end of the spring 38 away from the sliding rod 37 is fixed to the side of the fixed plate 36 away from the clamping plate 35. A bolt 5 is provided on the surface of the rocker arm 30. The bolt 5 passes through the rocker arm 30 and is threadedly connected to the rocker arm 30. The screw 32 is provided with two opposite threads. When the rocker arm 30 is rotated clockwise, the screw 32 drives the moving plate 33 to move closer to each other. At this time, the movable plate 34 moves synchronously. The surface of the movable plate 34 abuts against the surface of the sliding rod 37, which can drive the clamping plate 35 to move closer to the infrared oil meter body 1, so that the clamping plate 35 clamps and fixes the infrared oil meter body 1. Reversing the rocker arm 30 will release it.

[0028] A limiting groove 40 is formed on the inner wall of the housing 2. Slide grooves 41 are formed on both sides of the movable plate 34. A slider 42 is slidably connected to the inner wall of slide groove 41. A spring 43 is fixed to the outer surface of the slider 42. The end of spring 43 away from the slider 42 is fixed to the inner wall of slide groove 41. A slide groove 45 is formed at the end of the slider 42 away from spring 43. A limiting block 46 is slidably connected to the inner wall of slide groove 45. A spring 47 is fixed to the outer surface of the limiting block 46. The end of spring 47 away from the limiting block 46 is fixed to the inner wall of slide groove 45. An abutment groove 44 is formed on the outer surface of the slider 42. A plug rod 48 is fixed to the side of the fixed plate 36 away from the clamping plate 35. An insertion hole 49 is formed on the side of the movable plate 34 near the fixed plate 36. The insertion hole 49 interacts with slide groove 41. The contact groove 44 is set as an inclined surface, and the end of the limiting block 46 away from the spring 47 is also set as an inclined surface. The clamping plate 35 clamps and fixes the infrared oil meter body 1. When the rocker arm 30 is continuously rotated, the insertion rod 48 moves into the insertion hole 49. The surface of the insertion rod 48 abuts against the inner wall of the contact groove 44, which drives the slider 42 to move closer to the limiting groove 40. Simultaneously, it drives the limiting block 46 to move. The limiting block 46 enters the limiting groove 40. At this time, the inner wall of the limiting groove 40 abuts against the side of the limiting block 46 away from the inclined surface, which prevents the movable plate 34 from moving further and the clamping plate 35 from moving further. At this time, the screw 32 and the rocker arm 30 cannot continue to rotate, which avoids excessive clamping force and deformation of the infrared oil meter body 1 due to failure to stop rotating the rocker arm 30 in time, thus affecting normal use.

[0029] The outer surface of the infrared oil meter body 1 is equipped with a sealing cover 6, which facilitates the sealing of the housing 2 and prevents external dust and moisture from entering the housing 2, thus avoiding damage to the infrared oil meter body 1.

[0030] In use, place the infrared oil meter body 1 into the housing 2. Then, rotate bolt 5 to disengage it from the surface of housing 2. Rotate rocker arm 30 normally. At this time, screw 32 drives moving plate 33 to move closer together, and movable plate 34 moves synchronously. The surface of movable plate 34 abuts against the surface of sliding rod 37, causing clamping plate 35 to move closer to infrared oil meter body 1, thus clamping and fixing the infrared oil meter body 1. Simultaneously, spring 38 is compressed. When the operator continues to rotate rocker arm 30, insertion rod 48 moves closer to insertion hole 49 and into insertion hole 49. At this time, the surface of insertion rod 48... When the contact groove 44 comes into contact with the inner wall, the slider 42 moves closer to the limiting groove 40, simultaneously moving the limiting block 46. At this time, the second spring 43 is stretched. When the surface of the limiting block 46 contacts the inner wall of the housing 2, the limiting block 46 moves into the second sliding groove 45, and the third spring 47 is compressed. When the position of the limiting block 46 is parallel to the limiting groove 40, the third spring 47 is released, allowing the limiting block 46 to enter the limiting groove 40. At this time, the inner wall of the limiting groove 40 contacts the side of the limiting block 46 away from the inclined surface, preventing the movable plate 34 from moving further and the clamping plate 35 from moving further. At this time, the screw 32 and the rocker arm 3... To prevent the rocker arm 30 from rotating further, it must be stopped in time to avoid excessive clamping force, which could cause deformation of the infrared oil meter body 1 and affect normal use. During transportation, closing the sealing cover 6 will prevent external dust and moisture from entering the housing 2 and damaging the infrared oil meter body 1. Simultaneously, rotating bolt 5 will cause it to contact the surface of the housing 2, limiting the rocker arm 30 and preventing accidental activation that could affect the stability of the infrared oil meter body 1. When the infrared oil meter body 1 needs to be removed for use, loosen bolt 5 again and reverse the rocker arm 30. At this point, the inclined surface of the limiting block 46 and the limiting groove will... The inner wall of 40 abuts, causing the limiting block 46 to move into the second slide groove 45, which does not affect the normal reset of the movable plate 34 or the normal reverse rotation of the rocker arm 30. At this time, the first spring 38 drives the clamping plate 35 away from the infrared oil analyzer body 1, the insertion rod 48 disengages from the insertion hole 49, and the second spring 43 returns to its original position, driving the slider 42 and the limiting block 46 to reset. The infrared oil analyzer body 1 can then be taken out normally for use. The infrared oil analyzer is based on infrared spectrophotometry and quantitatively analyzes the oil content in water samples by detecting the absorption characteristics of oil substances in a specific infrared band. The model of the infrared oil analyzer body 1 is: JLBG-126 infrared oil analyzer.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
