Description

Technical Field

[0001] The present application relates to the technical field of liquid level measurement, and in particular to an integrally formed magnetic flap liquid level gauge display. Background Art

[0002] The magnetic flap level gauge is a product developed and produced based on the similar products at home and abroad and in accordance with the magnetic level gauge standard HG / T21584-95 promulgated by the former Ministry of Chemical Industry. It is used for medium level detection of various towers, tanks, tanks, spherical containers, boilers and other equipment.

[0003] The magnetic flap level gauge (also called magnetic float level gauge) is developed based on the buoyancy principle and magnetic coupling. When the liquid level in the measured container rises or falls, the magnetic float in the level gauge body tube also rises or falls. The permanent magnet in the float is transmitted to the magnetic flip column indicator through magnetic coupling, driving the red and white flip column to flip 180°. When the liquid level rises, the flip column changes from white to red, and when the liquid level drops, the flip column changes from red to white. The red and white intersection of the indicator is the actual height of the liquid level inside the container, thereby achieving a clear indication of the liquid level.

[0004] The display body of the magnetic flap level gauge in the prior art is usually composed of an aluminum display profile, an acrylic window panel, an upper first head and a lower first head, red and white beads, a bead bracket, etc. However, when the magnetic flap level gauge is in use, the acrylic window panel on the display body is prone to collision or scratching, reducing the visual clarity of the acrylic window panel, and therefore needs further improvement. Utility Model Content

[0005] In order to reduce the possibility of scratches on the surface of a transparent display shell, the present application provides an integrally formed magnetic flap liquid level gauge display.

[0006] The one-piece magnetic flap liquid level gauge display provided in this application adopts the following technical solution:

[0007] An integrally formed magnetic flap liquid level gauge display comprises a protective shell and a transparent display shell built into the protective shell, wherein the upper end of the protective shell is provided with a viewing window connected to an inner cavity, and the transparent display shell is provided with a bracket built into the transparent display shell, wherein the bracket is rotatably connected to a magnetic flap column, and a plurality of magnetic flap columns are provided and distributed along the length direction of the bracket.

[0008] By adopting the above technical solution, the transparent display shell is built into the protective shell, and the protective shell protects the transparent display shell, thereby effectively reducing the possibility of scratches on the surface of the transparent display shell, improving the clarity of the surface of the transparent display shell, and observing the flipping changes of the magnetic flip column in the transparent display shell through the viewing window.

[0009] Preferably, both ends of the protective shell are open, and both ends of the protective shell are provided with a first head for closing the port of the protective shell.

[0010] By adopting the above technical solution, the installed transparent display shell is slidably inserted into the inner cavity of the protective shell from the port of the protective shell, and then the port of the protective shell is sealed by the first head, effectively preventing the transparent display shell from sliding out of the port of the protective shell.

[0011] Preferably, both ends of the transparent display shell are open, and both ends of the protective shell are provided with second heads for closing the ports of the transparent display shell.

[0012] By adopting the above technical solution, after the installed bracket is slidably inserted into the inner cavity of the transparent display shell from the port of the transparent display shell, the port of the transparent display shell is blocked by the second head, effectively preventing the bracket from sliding out of the port of the transparent display shell.

[0013] Preferably, a limiting component for slidingly limiting the transparent display housing is provided at one end of the protective shell.

[0014] By adopting the above technical solution and adding a limit component, the transparent display shell is slidingly limited, which effectively reduces the possibility of displacement of the transparent display shell in the protective shell and ensures the accuracy of liquid level detection.

[0015] Preferably, a limit hole is provided on the side wall of the protective shell, the limit assembly includes a limit rod slidably penetrated through the limit hole, an outer wall at one end of the transparent display shell abuts against one of the first heads, and the limit rod abuts against the outer wall at the other end of the transparent display shell.

[0016] By adopting the above technical solution, the installed transparent display shell is slidably inserted into the inner cavity of the protective shell from one port of the protective shell, and then the port of the protective shell is sealed by the first head, and the outer wall of one end of the transparent display shell is abutted against one of the first heads, and then slidably penetrated through the limit rod, so that the limit rod is abutted against the outer wall of the other end of the transparent display shell, thereby effectively fixing the transparent display shell.

[0017] Preferably, the limiting hole passes through another outer wall of the protective shell, the limiting rod is a bolt, and the limiting assembly also includes a nut disposed outside the protective shell and threadedly connected to the bolt, and the end face of the nut abuts against the outer wall of the protective shell.

[0018] By adopting the above technical solution, a nut is locked on the end of the limiting rod, which effectively prevents the limiting rod from slipping out of the limiting hole.

[0019] Preferably, the end of the limit rod is fixedly connected to a force plate externally disposed on the protective shell, and the limit assembly also includes a spring arranged between the force plate and the outer wall of the protective shell to force the force plate to slide toward the protective shell under normal conditions.

[0020] By adopting the above technical solution, under normal circumstances, the spring forces the force plate to slide toward the direction close to the protective shell, so that the end of the limit rod extends to the inner cavity of the protective shell. When assembling the transparent display shell, the force plate is first pulled outward to make the end of the limit rod slide toward the outside of the protective shell, providing an escape space for the transparent display shell. At this time, the spring undergoes elastic deformation and has elastic potential energy. Subsequently, the transparent display shell is slidably inserted into the inner cavity of the protective shell, and the force applied to the force plate is removed. The spring forces the limit rod to slide and reset, so that the limit rod extends into the protective shell and abuts against the end face of the transparent display shell.

[0021] Preferably, the protective shell is fixedly connected to an indicator plate located at one side of the viewing window, and scale lines are arranged on the indicator plate.

[0022] By adopting the above technical solution, the liquid level height is directly obtained by the scale line on the indicator plate corresponding to the magnetic flip column rotating at the top.

[0023] In summary, the utility model has the following beneficial effects:

[0024] 1. By embedding the transparent display shell in the protective shell, the protective shell protects the transparent display shell, effectively reducing the possibility of scratches on the surface of the transparent display shell, improving the clarity of the surface of the transparent display shell, and observing the flipping changes of the magnetic flip column in the transparent display shell through the viewing window;

[0025] 2. Add a limiter component to limit the sliding of the transparent display housing, effectively reducing the possibility of displacement of the transparent display housing in the protective shell and ensuring the accuracy of liquid level measurement;

[0026] 3. The liquid level height can be directly obtained by the scale line on the indicator plate corresponding to the rotating magnetic column at the top. BRIEF DESCRIPTION OF THE DRAWINGS

The upper end surface of the protective shell 1 is integrally formed with an indicator plate 13 located on one side of the viewing window 11, and the indicator plate 13 is provided with scale lines.

[0036] Both ends of the transparent display shell 2 are open, and both ends of the protective shell 1 are provided with a second head 21 that closes the port of the transparent display shell 2. The second head 21 is an acrylic head. In this embodiment, the second head 21 and the transparent display shell 2 are glued together by sealing glue. The transparent display shell 2 has a built-in bracket 3, and the outer sides of the two ends of the bracket 3 are respectively abutted against the inner walls of the two second heads 21. The upper part of the inner wall of the transparent display shell 2 is integrally formed with a limit strip 22, and the upper end face edge of the bracket 3 is fixed with an elastic pad strip 31 that abuts against the lower end face of the limit strip 22. The bracket 3 is rotatably connected to a magnetic flip column 4, and a plurality of magnetic flip columns 4 are provided and distributed along the length direction of the bracket 3.

[0037] In this embodiment, the second end cap 21 on one end of the transparent display housing 2 abuts against the inner wall of the first end cap 12 on one end of the protective housing 1, and a limit assembly 5 for slidingly limiting the transparent display housing 2 is provided at one end of the protective housing 1. Specifically, the outer wall of the protective housing 1 is penetrated with a limit hole 14 along its width direction, and the limit assembly 5 includes a limit rod 51 and a nut 52 that are slidably penetrated in the limit hole 14. In this embodiment, the limit rod 51 is a bolt, and the nut 52 is externally disposed on the protective housing 1 and threadedly connected to the threaded section of the bolt.

[0038] The implementation principle of the embodiment of the present application is: by embedding the transparent display shell 2 into the protective shell 1, the protective shell 1 protects the transparent display shell 2, effectively reducing the possibility of scratches on the surface of the transparent display shell 2, and improving the clarity of the surface of the transparent display shell 2. The flipping changes of the magnetic flip column 4 in the transparent display shell 2 are observed through the viewing window 11, and the liquid level height is directly obtained through the scale line on the indicator plate 13 corresponding to the magnetic flip column 4 rotating at the top.
