Description

Technical Field

[0001] This utility model relates to the field of SDI pollution measuring instrument technology, and in particular to an SDI pollution measuring instrument that is easy to maintain. Background Technology

[0002] In modern industrial production and water quality monitoring, SDI pollution analyzers play a crucial role. They can effectively detect the degree of pollution in water, providing key data support for industrial water treatment, wastewater treatment, and drinking water quality monitoring, ensuring the smooth operation of production processes and the safety of people's drinking water. With the continuous development of industry and the increasing requirements for water quality, the demand for SDI pollution analyzers is also increasing, and their application scenarios are becoming more and more extensive.

[0003] Currently, many SDI pollution analyzers on the market have numerous structural design deficiencies, causing significant inconvenience to maintenance. Many analyzers use an integrated encapsulated structure, with the main body fixed inside the instrument. If the main body malfunctions, maintenance personnel need to disassemble multiple complex components to access it, making the disassembly and assembly process cumbersome, time-consuming, and labor-intensive. In some analyzers, the structural design for fixing the main body is unreasonable, perhaps relying on multiple bolts for tight fastening. During disassembly and installation, not only are various tools required, but bolt rust and stripping can also lead to disassembly difficulties, prolonging maintenance time and increasing repair costs. Furthermore, when the instrument is opened for operation, some lack a stable support structure, causing the opened cover to wobble. This not only affects the operator's work efficiency but may also damage the analyzer if the cover is accidentally closed, even threatening the operator's safety. Therefore, this application proposes an SDI pollution analyzer that facilitates maintenance to address these technical problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an SDI pollution measuring instrument that is easy to maintain. When it is necessary to disassemble the main body of the measuring instrument, simply turn the knob to move the moving frame and remove the limit on the tenon, and the main body of the measuring instrument can be easily taken out from the first box. When the second box is opened, the limiting structure composed of connecting rod one, connecting rod two, rotating rod, sliding sleeve and tenon can stably fix the second box.

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

[0006] An easy-to-maintain SDI pollution analyzer includes a housing 1. A housing 2 is rotatably connected to the top of housing 1, and housing 2 is connected to the front end of housing 1 via a locking assembly.

Connecting rods 2 are fixedly connected to the opposite ends of the two rotating rods, and limit assemblies are slidably connected to the outer walls of the two rotating rods. Both connecting rods 2 are rotatably connected to the bottom end of housing 2. A bidirectional lead screw is rotatably connected to the rear side of the inner wall of housing 1. Two movable frames are connected to the outer wall of the bidirectional lead screw via threaded sleeves. Both movable frames are slidably connected to the inner wall of housing 1. Tenon strips are slidably connected to the adjacent ends of the two movable frames. Fixed frames are fixedly connected to the adjacent ends of the two tenon strips. The analyzer is mounted on the inner wall of the fixed frames.

[0007] Furthermore, the limiting component includes a sliding sleeve located on the outer wall of the two connecting rods, and each of the two sliding sleeves is fixedly connected to a tenon at one end.

[0008] Furthermore, the locking assembly includes a fixing plate located at the front end of the first housing, a male buckle rotatably connected to the front end of the fixing plate, and a female buckle fixedly connected to the front end of the second housing, the female buckle being connected to the male buckle.

[0009] Furthermore, a sliding rod is fixedly connected to one inner wall of the housing, and the sliding rod is slidably connected to the front end of the movable frame.

[0010] Furthermore, a knob is fixedly connected to the right end of the bidirectional lead screw, and an anti-slip strip is provided on the outer wall of the knob.

[0022] 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.

[0023] Reference Figures 2-4 This utility model provides an embodiment of an SDI pollution analyzer that is easy to maintain, comprising a housing 1, a housing 2 rotatably connected to the top of the housing 1, and the housing 2 being connected to the front end of the housing 1 via a fixing plate 4, a male buckle 6 and a female buckle 5. Two connecting rods 14 are rotatably connected to the top of the housing 1, and rotating rods 16 are rotatably connected to the inner walls of the two connecting rods 14. Connecting rods 15 are fixedly connected to the two rotating rods 16 at opposite ends, and sliding sleeves 17 and tenons 18 are slidably connected to the outer walls of the two rotating rods 16. Connecting rods 15 are rotatably connected to the bottom of the housing 2. A bidirectional lead screw 8 is rotatably connected to the rear side of the inner wall of the housing 1, and two movable frames 9 are connected to the outer wall of the bidirectional lead screw 8 via threaded sleeves. The two movable frames 9 are slidably connected to the inner wall of the housing 1, and tenons 10 are slidably connected to the near ends of the two movable frames 9. Fixed frames 11 are fixedly connected to the near ends of the two tenons 10, and the analyzer is provided on the inner wall of the fixed frames 11.

[0024] Specifically, rotating housing 2 upwards causes the connecting rod 14 (rotatably connected to the top of housing 1) and connecting rod 15 (rotatably connected to the bottom of housing 2) to move along with the rotation of housing 2. After a period of use, if maintenance of the main body 12 is required, rotating the knob 7 (fixed to the right end of the bidirectional lead screw 8) causes the bidirectional lead screw 8 to rotate. The outer wall of the bidirectional lead screw 8 is connected to two movable frames 9 via threaded sleeves. Therefore, the rotation of the bidirectional lead screw 8 causes the movable frames 9 to slide along the inner wall of housing 1. During this sliding process, the movable frames 9 release the limiting force on the tenon 10, allowing the main body 12 of the measuring instrument to be removed from housing 1 for maintenance and other operations.

[0025] Reference Figure 1 , Figure 3 and Figure 4 Among them, the sliding sleeves 17 are located on the outer walls of the two connecting rods 15, and the two sliding sleeves 17 are fixedly connected to the tenons 18 at one end. The fixed plate 4 is located at the front end of the box 1, and the front end of the fixed plate 4 is rotatably connected to the male buckle 6. The front end of the box 2 is fixedly connected to the female buckle 5, and the female buckle 5 is connected to the male buckle 6. The inner wall of the box 1 is fixedly connected to the sliding rod 13, and the sliding rod 13 is slidably connected to the front end of the moving frame 9. The right end of the double-acting screw 8 is fixedly connected to the knob 7, and the outer wall of the knob 7 is provided with anti-slip strips. The top of the box 2 is rotatably connected to the handle 3. The inner wall of the fixed frame 11 is provided with the measuring instrument body 12.

[0026] Specifically, the operation involves rotating the male buckle 6 on the front fixing plate 4 of box 1 to separate it from the female buckle 5 fixedly connected to the front of box 2. This cancels the engagement between box 1 and box 2, allowing them to separate. When box 2 rotates to a position perpendicular to box 1, the sliding sleeve 17 is moved along the rotating rod 16. Since a tenon 18 is fixedly connected to one end of the sliding sleeve 17, moving the sliding sleeve 17 allows the tenon 18 to be inserted into the groove of connecting rod 14. After the tenon 18 is inserted into the groove, it limits the movement of connecting rod 14 and connecting rod 2 15, thus stably fixing box 2. The sliding rod 13 is fixed to the inner wall of box 1, providing guidance for the sliding of the moving frame 9 and ensuring the stability of the moving frame 9 during movement. The anti-slip strip on the outer wall of the knob 7 increases the friction between the hand and the knob 7, making it easier to apply force and rotate. The main body 12 of the measuring instrument is the core component for SDI pollution measurement, realizing the function of detecting the pollution level of relevant samples.

[0027] Working principle: Hold handle 3 to lift housing 1 and housing 2, move the measuring instrument to the appropriate position, then use the male buckle 6 to release the engagement with the female buckle 5, allowing housing 1 and housing 2 to separate. Rotate housing 2 upwards. As it rotates, connecting rod 14 and connecting rod 25 will move with the rotation of housing 2. When housing 2 is rotated to a perpendicular position to housing 1, move the sliding sleeve 17 on the rotating rod 16 to insert the tenon 18 into the groove of connecting rod 14, limiting connecting rod 14 and connecting rod 25, thereby fixing housing 2. Then, the measuring instrument body 12 can be used for measurement. When the measuring instrument body 12 needs maintenance, turn the knob 7 to rotate the bidirectional lead screw 8, thereby moving the moving frame 9 to release the limiting of the tenon 10. Then, the measuring instrument body 12 can be removed from housing 1 for maintenance.

[0028] 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.
