Description

Technical Field

[0001] The utility model is applicable to the technical field of coulometric trace moisture meters, and particularly relates to a coulometric trace moisture meter which is easy to carry. Background Art

[0002] At present, the Karl Fischer coulometric method (KF coulometric method) is used to determine the water content in samples. It overcomes the shortcomings of Karl Fischer titration instruments such as low accuracy, large amount of electrolyte, and complicated operation. It utilizes advanced automatic control circuits, large electrolytic currents, and current automatic control technology, and the measurement results are directly displayed digitally.

[0003] However, the coulometric trace moisture meter currently used has two sets of corresponding electrolytic electrode ends at the top when in use, and the two sets of electrolytic electrode ends cannot be quickly and conveniently fixed when it is carried and moved, which causes the electrode ends to shake easily when moving and contact and collide with the surface of the moisture meter, which not only affects the overall carrying and transportation speed of the moisture meter, but also causes damage to it and affects the normal use of subsequent electrode end detection. Therefore, we propose a portable coulometric trace moisture meter. Utility Model Content

[0004] The main purpose of the utility model is to provide a portable coulometric trace moisture meter, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A portable coulometric micro-moisture meter comprises a housing, a display screen is fixedly mounted on the top surface of the housing, detection electrode ends are mounted on both ends of the top side of the housing, a sliding plate is slidably mounted on the top side of the housing, and a transmission frame is fixedly mounted laterally on the inner side of the housing;

[0007] A rotating screw is rotatably installed inside the transmission frame through a bearing, a transmission sleeve is movably sleeved on the outer surface of the rotating screw, a transmission frame is vertically fixedly installed on the outer top surface of each transmission sleeve, and the transmission frame is slidably installed inside the top of the transmission frame, a transmission rod is vertically fixedly installed on the top surface of the transmission frame, and the transmission rod penetrates and is slidably installed inside the top of the casing, both sides of the top of the casing are provided with limiting grooves, and the transmission rod penetrates and is slidably installed inside the limiting grooves;

[0008] The top of the transmission rod and the bottom surface of the sliding plate are fixedly connected, and the two side surfaces of the top of the sliding plate are fixedly installed with a clamping frame.

[0009] By adopting the above technical scheme, the positions of the sliding plate and the clamping frame can be adjusted under the rotational transmission action of the rotating screw on the transmission sleeve and the synchronous transmission action of the transmission frame and the transmission rod, so that when the casing is carried and moved, the detection electrode end can be bent so that it is clamped inside the clamping frame, and then the detection electrode end can be installed and reinforced to avoid arbitrary shaking of the detection electrode end and affect its transportation portability, thereby improving the safety of carrying and moving the entire moisture meter.

[0010] As an optional solution of the technical solution of the present application, a servo motor is fixedly mounted on the outer surface of the transmission frame, and the side of the servo motor transmission shaft is fixedly connected to the outer surface of the rotating screw through a coupling.

[0011] By adopting the above technical solution, the driving force for the rotation of the rotating screw is provided through the structural function of the servo motor.

[0012] As an optional solution of the technical solution of the present application, a limit baffle is detachably mounted on the top surface of each of the clamping frames by means of bolts.

[0013] By adopting the above technical solution, the upper fixing processing of the detection electrode end during placement is achieved through the structural function of the limit baffle.

[0014] As an optional solution of the technical solution of the present application, an anti-skid friction pad is fixedly bonded to the inner side wall of each of the snap-fit ​​frames.

[0015] By adopting the above technical solution, the stability of the detection electrode terminal during placement is improved through the structural effect of the anti-slip friction pad.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is a portable coulometric micro moisture meter. A snap-fit ​​frame is provided on the top of the sliding plate, and the synchronous transmission action of the transmission frame and the transmission rod is combined. When the housing of the moisture meter needs to be transported and moved, the rotating screw is rotated to drive the sliding plate to move horizontally on the outside of the housing synchronously to adjust the positions of the sliding plate and the snap-fit ​​frame. When the housing is carried and moved, the detection electrode end can be bent and snapped into the inside of the snap-fit ​​frame, and then the detection electrode end can be installed and reinforced to avoid arbitrary shaking of the detection electrode end and affect its transportation portability, thereby improving the safety of the entire moisture meter when carried and moved.

[0018] 2. The technical solution of the present application is a portable coulometric trace moisture meter, in which a limit baffle is movably installed on the top of a clamping frame by means of bolts, so that after the detection electrode end is sleeved inside the clamping frame, the limit baffle can seal it from the top of the clamping frame, thereby further ensuring the stability of the detection electrode end placed inside the clamping frame.

DETAILED DESCRIPTION

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: a portable coulometric micro moisture meter, a servo motor 26 is fixedly mounted on the outer surface of a transmission frame 23, and the side of the transmission shaft of the servo motor 26 is fixedly connected to the outer surface of a rotating screw 24 through a coupling.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a rotating screw 24 is rotatably installed inside the transmission frame 23 through a bearing, and a transmission sleeve 25 is movably sleeved on the outer surface of the rotating screw 24. A transmission frame 27 is vertically fixedly installed on the outer top surface of each transmission sleeve 25, and the transmission frame 27 is slidably installed inside the top of the transmission frame 23. A transmission rod 28 is vertically fixedly installed on the top surface of the transmission frame 27, and the transmission rod 28 is slidably installed inside the top of the casing 1. Limiting grooves 29 are provided on both sides of the top of the casing 1, and the transmission rod 28 is slidably installed inside the limiting grooves 29.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a display screen 11 is fixedly mounted on the top surface of the casing 1, and detection electrode ends 12 are mounted on both ends of the top side of the casing 1.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), the top of the transmission rod 28 is fixedly connected to the bottom surface of the sliding plate 2, and the two side surfaces of the top of the sliding plate 2 are fixedly installed with a clamping frame 21, and the top surface of each clamping frame 21 is detachably installed with a limit baffle 22 by bolts.

[0027] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), the inner wall of each clamping frame 21 is fixedly bonded with an anti-skid friction pad 3.

[0028] During operation, when the housing 1 of the coulometric micro moisture meter needs to be carried and transported as a whole, the servo motor 26 is turned on through an external control switch to make it run and drive the rotating screw 24 to rotate synchronously. Combined with the guiding and limiting effect of the limiting groove 29 on the transmission rod 28, the transmission sleeve 25 sleeved on the surface of the rotating screw 24 can be driven to move horizontally synchronously. Under the transmission effect of the transmission frame 27 and the transmission rod 28, a horizontal driving force is provided to the sliding plate 2, so that the sliding plate 2 can move on the outer surface of the housing 1. After moving and adjusting the position of the clamping frame 21 so that the clamping frame 21 can be away from the detection electrode end 12, after tightening the bolts on both sides of the limit baffle 22, the limit baffle 22 is detached from the top surface of the clamping frame 21, the detection electrode end 12 is pressed down to bend it and placed inside the clamping frame 21, and then the limit baffle 22 is attached to the top surface of the clamping frame 21, and one side of the detection electrode end 12 is clamped and fixed, and then the casing 1 is held and carried for transportation.
