Description

Technical Field

[0001] This utility model relates to the field of acid-base detection technology, specifically to an experimental device for detecting the acid-base properties of foaming agents. Background Technology

[0002] pH refers to the strength of an aqueous solution's acidity or alkalinity. In an aqueous solution, when the concentration of hydrogen ions is greater than that of hydroxide ions, the solution is acidic; the higher the concentration of hydrogen ions, the stronger the acidity. Conversely, the solution is alkaline; the higher the concentration of hydroxide ions, the stronger the alkalinity. When the concentrations of hydrogen ions and hydroxide ions are equal, the solution is neutral. In the production of foaming agents, it is necessary to test the pH.

[0003] However, many foam agent acid testing equipment currently lacks dust prevention measures during use. If the equipment is not used for a period of time, a lot of dust will accumulate on the surface, and it is not convenient to adjust the height of the detection head in real time. Therefore, it is necessary to design a foam agent acidity and alkalinity testing equipment. Utility Model Content

[0004] The purpose of this invention is to provide a foaming agent acid-base testing experimental device, which solves the problem that many current foaming agent acid testing experimental devices lack dust prevention measures during use, and the surface of the device will be covered with a lot of dust after a period of non-use, and it is not convenient to adjust the height of the detection head in real time.

[0005] The technical solution of this utility model is as follows:

[0006] A foaming agent pH testing device includes a main body, with sliding plates slidably connected to both sides of the main body. A protective plate is fixedly connected to the top of the sliding plates. Vertical plates are fixedly connected to the top of the main body at both ends of the protective plates. Stops are fixedly connected to the surface of the vertical plates. A vertical rod is fixedly connected to the main body below the protective plate. A control ring is threadedly connected to the surface of the vertical rod. A connecting plate slidably connected to the vertical rod is rotatably connected to the top of the control ring. A mounting plate slidably connected to the vertical rod is fixedly connected to the top of the connecting plate. A limiting rod fixedly connected to the top of the vertical rod is slidably connected to the interior of the mounting plate. A positive and negative screw is rotatably connected to one side of the mounting plate. Two sets of clamps slidably connected to the mounting plate are threadedly connected to the surface of the positive and negative screw. A test pen is held in the inner wall of the clamps. A second spring is fixedly connected to one side of the vertical plate. A baffle slidably connected to the bottom of the second spring is fixedly connected to the vertical plate.

[0007] Preferably, a connecting plate is fixedly connected to the top of the device body, a sliding rod is slidably connected inside the connecting plate, and a first spring is fixedly connected to the connecting plate at both the top and bottom of the sliding rod, and a fixing plate fixedly connected to the sliding rod is fixedly connected to the tail of the first spring.

[0008] Preferably, the skateboard has a "T" shaped structure, and the vertical plate covers both ends of the skateboard.

[0009] Preferably, both the stop and the baffle are located on the movement trajectory of the skateboard, and the baffle is in close contact with the skateboard through a second spring.

[0010] Preferably, the control ring rotates to cause the connecting plate and the mounting plate to move horizontally up and down along the vertical rod, and the limiting rod is in close contact with the mounting plate.

[0011] Preferably, the clamping surfaces of the two sets of clamping plates are provided with an anti-slip rubber layer, and the two sets of clamping plates form a clamping structure through positive and negative lead screws.

[0012] Preferably, the test pen is installed with its orientation vertically downwards, and a circular placement area is provided directly below the test pen on the top of the device body.

[0013] Preferably, the top of the fixing plate is inclined, and six sets of fixing plates are equidistantly arranged.

[0014] Preferably, the slide bar is arranged perpendicularly to the fixed plate, and the fixed plate is clamped by a first spring.

[0015] Preferably, the clamping surfaces of all six sets of fixing plates are provided with anti-slip rubber strips.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting up a protective plate, the top of the equipment body can be blocked, and with the action of the vertical plate, the sides of the equipment body can be blocked, thus protecting the equipment body and preventing dust from falling on it. By setting up a stop and baffle, the slide can be limited and fixed, thereby fixing the protective plate. When it is necessary to remove the protective plate, pull the baffle upward to make the baffle detach from the slide, and the slide can be pulled out to remove the protective plate. When it is necessary to adjust the height of the test pen, rotate the control ring. When it rotates, it will drive the connecting plate and the mounting plate to descend along the vertical rod. The top of the limit rod will also descend along the top of the vertical rod to adjust the height of the test pen and control the test pen to enter the container to test the foaming agent.

[0018] 2. By setting a fixing plate, the container containing foaming agent is pushed down onto the fixing plate. Since the top of the fixing plate is inclined, when it is pushed, it will drive the slide rod to slide along the connecting plate, so that the container is placed on the top of the equipment body. Under the push of the first spring, the fixing plate will fit tightly with the container, thereby fixing the container. By setting a clamping plate, the clamping plate can be controlled to form a clamping and fixing state for the test pen by rotating the positive and negative screws. Attached Figure Description
