Description

Technical Field

[0001] The utility model relates to the technical field of moisture measuring instruments, in particular to a protective device for moisture measuring instruments. Background Art

[0002] In 1935, German Karl Fischer invented a new method for determining water content: using the redox reaction of iodine and sulfur dioxide to react quantitatively with water in an environment of organic base and methanol. The sample is titrated continuously with an iodine-containing reagent, and the method for determining the end point is to observe the color change when iodine is excessive. This is the original Karl Fischer water titration method.

[0003] Currently, mature moisture analyzers are available on the market, but such instruments are often directly exposed to the outside, and the measuring tanks are mostly glass containers, which are easily damaged, thus affecting the subsequent use of the equipment.

[0004] In the prior art, a Chinese patent with a publication number of CN210690383U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: it includes a shell and a base installed at the bottom of the shell, the shell is connected to the measuring instrument body through a retracting mechanism, and a rectangular opening is opened on the right side wall of the shell, and a locking mechanism matching the rectangular opening is arranged on the right side of the shell. The utility model can ensure the integrity of the measuring instrument when it is idle by retracting and sending the measuring instrument, and can also prevent dust and the like from invading the measuring instrument and causing its unexpected failure, thus realizing the protection and storage of the measuring instrument to the greatest extent and greatly extending the service life of the measuring instrument. However, the device can only reduce the problems caused by the bad environment such as temperature. When encountering external environmental vibration, the device cannot effectively solve the influence of vibration on the detection results. Summary of the invention

[0005] The purpose of the utility model is to provide a protective device for a moisture analyzer to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A protective device for a moisture meter comprises a box body, a box door is arranged on one side of the box body, the box door is slidably connected to the box body, a handle is fixedly connected to the box door, a first rack is fixedly connected to one side of the box door, a first shaft body and a second shaft body are respectively arranged in the box body, the first shaft body and the second shaft body are respectively rotatably connected to the box body, a movable plate is arranged in the box body, a slide bar is fixedly connected to the lower part of the movable plate, a first slide groove is opened in the box body, the slide bar is slidably connected to the first slide groove, a second rack is fixedly connected to one side of the movable plate, a power transmission component for transmitting power is connected inside the box body, a support shaft is symmetrically arranged on one side of the movable plate, a support plate is slidably connected to the support shaft, and a stabilizing component for reducing vibration is connected below the support plate.

[0008] When the moisture analyzer needs to be placed in the protective device, the box door is moved by pushing and pulling the handle. At this time, the movement of the box door will drive the power transmission component to work through the first rack, and then the power transmission component will drive the rack to move to achieve the purpose of moving the moving plate. At this time, the movement of the moving plate will drive the supporting plate slidably connected thereto to move outward, making it more convenient to place the moisture analyzer. When the moisture analyzer is placed, the stabilizing component under the supporting plate will cooperate with the pressure spring to adjust the height of the supporting plate so that it can be stably on the supporting plate, reducing the influence of external vibration of the box on the measurement result. Then the box door is closed, so that the moisture analyzer is inside the box to work.

[0009] A further improvement of the technical solution of the utility model is that the power transmission component includes a first gear and a second gear, the first gear is fixedly connected to the first shaft, the second gear is fixedly connected to the second shaft, a first pulley and a second pulley are fixedly connected below the first gear and the second gear respectively, the first pulley and the second pulley are connected by a belt drive, the first gear and the first rack are meshed with each other, and the second gear and the second rack are meshed with each other.

[0010] The above technical solution is adopted. In this solution, when the box door moves, the movement of the first rack will drive the first gear to rotate, and the rotation of the first gear will drive the first pulley highly connected to it to rotate. The first pulley transmits power to the second gear through the belt and the second pulley. The rotation of the second gear will drive the second rack meshing with it to move, thereby realizing that the support plate inside the box body is moved out by moving the box door, making it more convenient to place the moisture analyzer, greatly improving the working efficiency of the device.

[0011] A further improvement of the technical solution of the utility model is that: the stabilizing component includes a bottom plate, the bottom plate is fixedly connected to the box body, a support column is fixedly connected to the bottom plate, a top plate is arranged above the bottom plate, a column is fixedly connected to the side of the top plate close to the bottom plate, the column is slidably connected to the support column, an air leakage hole begins on the column, a plurality of blocks are symmetrically arranged on the top plate, the block is fixedly connected to the top plate, a slider is slidably connected to the block, one end of the slider is fixedly connected to an elastic spring, the other end of the elastic spring is fixed to the block, the block and the bottom plate are hinged by a connecting rod, one end of the support plate is fixedly connected to a pressure spring, the other end of the pressure spring is fixedly connected to the movable plate, and the support plate is slidably connected to the top plate.

[0012] The above technical solution is adopted. In this solution, when the moisture meter is placed on the support plate, the gravity of the moisture meter will cause the top plate to move downward. At this time, the slider is moved toward the end away from the pressure spring by the downward pressure of the top plate and the force of the connecting rod. At this time, the elastic spring is in a stretched state and the pressure spring is in a compressed state. At the same time, a sliding connection is set between the column and the support column to disperse the pressure. When the pressure on the top plate is unevenly distributed, the pressure can be dispersed by sliding the column and the support column to prevent the top plate from tilting and causing damage to the device. The sliding connection between the support plate and the top plate can effectively transfer the pressure to the top plate.

[0013] A further improvement of the technical solution of the utility model is that one end of the first rack and one end of the second rack are respectively fixedly connected to be provided with limiting teeth.

[0014] The above technical solution is adopted, in which limiting teeth are fixedly connected at one end of the first rack and the second rack respectively, because when the rack and the gear are meshed with each other, movement overload will cause the rack to be disengaged, which will not only affect the stability of the power transmission components, but may also cause the device to malfunction. The limiting teeth can provide additional resistance, making it difficult for the rack to be disengaged when working, so as to ensure that the normal operation of the device is not affected.

[0015] A further improvement of the technical solution of the utility model is that the top view of the support plate is a right-angled trapezoid.

[0016] According to the above technical solution, since the support plate moves together with the movable plate, when the door is opened, the movable door may collide with the support plate, causing the door to be unable to open. Setting the top view of the support plate to a right-angled trapezoid can effectively solve the problem of the door being unable to open.

[0017] A further improvement of the technical solution of the utility model is that the diameter of the first pulley is smaller than the diameter of the second pulley.

[0018] The above technical solution is adopted, in which the diameter of the first pulley is set smaller than the diameter of the second pulley because the distance that the movable plate can drive the support plate to move is limited, and the displacement distance of the box door cannot be achieved. This setting allows the support plate to extend to the maximum extent when the box door is just opened, thereby making the device run more smoothly.

[0019] A further improvement of the technical solution of the utility model is that the material of the box door is transparent glass.

[0020] The above technical solution is adopted, and the material of the box door is set to be transparent glass in this solution to facilitate the staff to observe the working condition of the moisture analyzer in the box in time, thereby improving the working efficiency of the device and the accuracy of the test data. If equipment failure, sample leakage, etc. occur, the transparent glass door allows the staff to discover and take corresponding measures in time to avoid safety accidents.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a protective device for a moisture analyzer. The limiting teeth are fixedly connected at one end of the first rack and the second rack respectively because when the rack and the gear are meshed with each other, the motion overload may cause the rack to be disengaged, which will not only affect the stability of the power transmission component, but also may cause the device to malfunction. The limiting teeth can provide additional resistance, making it difficult for the rack to be disengaged when working, so as to ensure that the normal operation of the device is not affected.

[0023] 2. The utility model provides a protective device for a moisture analyzer. Since the support plate moves together with the movable plate, when the box door is opened, the movable box door may collide with the support plate, resulting in the box door being unable to open. Setting the top view of the support plate to a right-angled trapezoid can effectively solve the problem of the box door being unable to open.

[0024] 3. The utility model provides a protective device for a moisture analyzer. The diameter of the first pulley is set to be smaller than the diameter of the second pulley because the distance that the movable plate can drive the support plate to move is limited and cannot achieve the distance of displacement of the box door. This setting allows the support plate to be extended to the maximum extent when the box door is just opened, thereby making the device run more smoothly.

[0025] 4. The utility model provides a protective device for a moisture analyzer. The material of the box door is transparent glass, which is convenient for the staff to observe the working condition of the moisture analyzer in the box in time, thereby improving the working efficiency of the device and the accuracy of the test data. If equipment failure, sample leakage, etc. occur, the transparent glass door allows the staff to discover and take corresponding measures in time, thereby avoiding the occurrence of safety accidents.

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the embodiments:

[0034] Example 1

[0035] like Figure 1 As shown, the utility model provides a protective device for a moisture analyzer, including a box body 1, a box door 2 is provided on one side of the box body 1, the box door 2 is slidably connected to the box body 1, a handle 3 is fixedly connected to the box door 2, a first rack 4 is fixedly connected to one side of the box door 2, a first shaft body 6 and a second shaft body 7 are respectively provided in the box body 1, the first shaft body 6 and the second shaft body 7 are respectively rotatably connected to the box body 1, a moving plate 8 is provided in the box body 1, a slide bar 9 is fixedly connected to the lower part of the moving plate 8, a first slide groove 10 is opened in the box body 1, the slide bar 9 is slidably connected to the first slide groove 10, a second rack 5 is fixedly connected to one side of the moving plate 8, a power transmission component for transmitting power is connected inside the box body 1, a support shaft 11 is symmetrically provided on one side of the moving plate 8, a support plate 26 is slidably connected to the support shaft 11, and a stabilizing component for reducing vibration is connected to the lower part of the support plate 26.

[0036] In this embodiment, when the moisture meter needs to be placed in the protective device, the box door 2 is moved by pushing and pulling the handle 3. At this time, the movement of the box door 2 will drive the power transmission component to work through the first rack 4, and then the rack is driven to move by the power transmission component to achieve the purpose of moving the movable plate 8. At this time, the movement of the movable plate 8 will drive the support plate 26 slidably connected thereto to move outward, making it more convenient to place the moisture meter. When the moisture meter is placed, the stabilizing component located under the support plate 26 will cooperate with the pressure spring 23 to adjust the height of the support plate 26 so that it can be stably placed on the support plate 26, reducing the influence of the external vibration of the box body 1 on the measurement result, and then the box door 2 is closed, so that the moisture meter is inside the box body 1 to work.

[0037] like Figure 3 As shown, in the present embodiment, preferably, the power transmission component includes a first gear 12 and a second gear 13, the first gear 12 is fixedly connected to the first shaft 6, the second gear 13 is fixedly connected to the second shaft 7, a first pulley 14 and a second pulley 15 are fixedly connected below the first gear 12 and the second gear 13, respectively, the first pulley 14 and the second pulley 15 are connected via a belt 16, the first gear 12 and the first rack 4 are meshed with each other, and the second gear 13 and the second rack 5 are meshed with each other.

[0038] When the box door 2 moves, the movement of the first rack 4 will drive the first gear 12 to rotate, and the rotation of the first gear 12 will drive the first pulley 14 highly connected thereto to rotate, and the first pulley 14 transmits power to the second gear 13 through the belt 16 and the second pulley 15, and the rotation of the second gear 13 will drive the second rack 5 meshing therewith to move, thereby achieving the removal of the support plate 26 inside the box body 1 by moving the box door 2, making it more convenient to place the moisture analyzer, thereby greatly improving the working efficiency of the device.

[0039] like Figure 3 As shown, preferably, the stabilizing component includes a bottom plate 17, which is fixedly connected to the box body 1, a support column 19 is fixedly connected to the bottom plate 17, a top plate 27 is arranged above the bottom plate 17, a column 18 is fixedly connected to the side of the top plate 27 close to the bottom plate 17, the column 18 is slidably connected to the support column 19, an air leakage hole begins to be provided on the column 18, a plurality of blocks 20 are symmetrically arranged on the top plate 27, the block 20 is fixedly connected to the top plate 27, a slider 21 is slidably connected to the block 20, one end of the slider 21 is fixedly connected to an elastic spring 22, the other end of the elastic spring 22 is fixed to the block 20, the block 20 and the bottom plate 17 are hinged by a connecting rod 24, one end of the support plate 26 is fixedly connected to a pressure spring 23, the other end of the pressure spring 23 is fixedly connected to the movable plate 8, and the support plate 26 is slidably connected to the top plate 27.

[0040] When the moisture meter is placed on the support plate 26, the gravity of the moisture meter will cause the top plate 27 to move downward. At this time, the slider 21 is moved toward the end away from the pressure spring 23 by the downward pressure of the top plate 27 and the force of the connecting rod 24. At this time, the elastic spring 22 is in a stretched state, and the pressure spring 23 is in a compressed state. At the same time, the column 18 and the support column 19 are provided with a sliding connection to disperse the pressure. When the pressure on the top plate 27 is unevenly distributed, the pressure can be dispersed by sliding the column 18 and the support column 19 to prevent the top plate 27 from tilting and causing damage to the device. The support plate 26 and the top plate 27 are provided with a sliding connection to effectively transfer the pressure to the top plate 27.

[0041] Example 2

[0042] like Figure 3 Figure 5 As shown, based on Example 1, the utility model provides a technical solution: preferably, one end of the first rack 4 and one end of the second rack 5 are respectively fixedly connected to be provided with a limiting tooth 25.

[0043] In this embodiment, the limiting teeth 25 are fixedly connected at one end of the first rack 4 and the second rack 5 respectively because when the rack and the gear are meshed with each other, the movement overload may cause the rack to be disengaged, which will not only affect the stability of the power transmission component, but may also cause the device to malfunction. The limiting teeth 25 can provide additional resistance, making it difficult for the rack to be disengaged when working, so as to ensure that the normal operation of the device is not affected.

[0044] like Figure 2 As shown, preferably, the diameter of the first pulley 14 is smaller than the diameter of the second pulley 15 .

[0045] The diameter of the first pulley 14 is set smaller than the diameter of the second pulley 15 because the distance that the movable plate 8 can drive the support plate 26 to move is limited, and the distance of displacement of the door 2 cannot be achieved. This setting allows the support plate 26 to be extended to the maximum when the door 2 is just opened, so that the device can run more smoothly.

[0046] Example 3

[0047] like Figure 2 As shown, based on Example 2, the utility model provides a technical solution: preferably, the top view of the support plate 26 is a right-angled trapezoid.

[0048] In this embodiment, because the support plate 26 moves together with the movable plate 8, when the door 2 is opened, the moving door 2 may collide with the support plate 26, resulting in the door 2 being unable to open. Setting the top view of the support plate 26 to a right-angled trapezoid can effectively solve the problem of the door 2 being unable to open.

[0049] Example 4

[0050] like Figure 1 As shown, based on Example 3, the utility model provides a technical solution: preferably, the material of the box door 2 is transparent glass.

[0051] In this embodiment, the material of the box door 2 is transparent glass to facilitate the staff to timely observe the working condition of the moisture analyzer in the box body 1, thereby improving the working efficiency of the device and the accuracy of the test data. If equipment failure, sample leakage, etc. occur, the transparent glass door allows the staff to discover and take corresponding measures in time to avoid safety accidents.

[0052] The following is a detailed description of the working principle of the protective device for the moisture analyzer.

[0053] like Figure 1-5As shown, when the moisture meter needs to be placed in the protective device, the box door 2 is moved by pushing and pulling the handle 3. At this time, the movement of the box door 2 will drive the power transmission component to work through the first rack 4, and then the rack is driven to move by the power transmission component to achieve the purpose of moving the movable plate 8. At this time, the movement of the movable plate 8 will drive the support plate 26 slidably connected thereto to move outward, making it more convenient to place the moisture meter. After the moisture meter is placed, the stabilizing component located under the support plate 26 will cooperate with the pressure spring 23 to adjust the height of the support plate 26 so that it can be stably placed on the support plate 26, reducing the influence of the external vibration of the box body 1 on the measurement result, and then the box door 2 is closed, so that the moisture meter is inside the box body 1 to work. When the box door 2 moves, the movement of the first rack 4 will drive the first gear 12 to rotate, and the rotation of the first gear 12 will drive the first pulley 14 highly connected thereto to rotate, and the first pulley 14 transmits power to the second gear 13 through the belt 16 and the second pulley 15, and the rotation of the second gear 13 will drive the second rack 5 meshing therewith to move, thereby achieving the removal of the support plate 26 inside the box body 1 by moving the box door 2, making it more convenient to place the moisture analyzer, thereby greatly improving the working efficiency of the device. When the moisture meter is placed on the support plate 26, the gravity of the moisture meter will cause the top plate 27 to move downward. At this time, the slider 21 is moved to the end away from the pressure spring 23 by the downward pressure of the top plate 27 and the force of the connecting rod 24. At this time, the elastic spring 22 is in a stretched state, and the pressure spring 23 is in a compressed state. At the same time, the column 18 and the support column 19 are provided with a sliding connection to disperse the pressure. When the pressure on the top plate 27 is unevenly distributed, the pressure can be dispersed by sliding the column 18 and the support column 19 to prevent the top plate 27 from tilting and causing damage to the device. The support plate 26 and the top plate 27 are provided with a sliding connection to effectively transmit the pressure to the top plate 27. The reason why the limiting teeth 25 are fixedly connected at one end of the first rack 4 and the second rack 5 is that when the rack and the gear are meshed with each other, the motion overload will cause the rack to be disengaged, which will not only affect the stability of the power transmission component, but also may cause the device to fail. The limiting teeth 25 can provide additional resistance to make it difficult for the rack to be disengaged when working, so as to ensure that the normal operation of the device is not affected. Because the support plate 26 moves together with the moving plate 8, when the door 2 is opened, the moving door 2 may collide with the support plate 26, resulting in the door 2 being unable to open. Setting the top view of the support plate 26 to be a right-angled trapezoid can effectively solve the problem of the door 2 being unable to open. The diameter of the first pulley 14 is set smaller than the diameter of the second pulley 15 because the distance that the moving plate 8 can drive the support plate 26 to move is limited and cannot achieve the distance that the door 2 is displaced. This setting allows the support plate 26 to be extended to the maximum when the door 2 is just opened, thereby making the device run more smoothly.The material of the box door 2 is transparent glass to facilitate the staff to timely observe the working condition of the moisture analyzer in the box 1, thereby improving the working efficiency of the device and the accuracy of the test data. If equipment failure or sample leakage occurs, the transparent glass door allows the staff to discover it in time and take corresponding measures to avoid safety accidents.

[0054] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
