Description

Technical Field

[0001] The utility model relates to a novel transparent shell structure of an ultrasonic water meter, which is used for protecting core components of the ultrasonic water meter and belongs to the technical field of ultrasonic water meters. Background Art

[0002] Currently, to achieve the required level of protection, common household ultrasonic water meter movements are typically glued. This glue-filling process requires a sponge pad to seal the transparent shell and the LCD display, and then the movement is sealed with glue from the back of the transparent shell. This process requires manual gluing of the sponge pad to a specified position on the transparent shell, which is difficult to align. This can easily lead to sponge leakage from the shell window, and after assembly, the transparent shell and the LCD display cannot be completely sealed, leading to glue overflow in the window. This results in low assembly efficiency and a reduced yield rate. Utility Model Content

[0003] The purpose of the utility model is to provide a new ultrasonic water meter transparent shell structure with a simple structure and convenient assembly. The machine replaces manual labor, and the glue injection is automated, thereby improving the assembly efficiency and stability, and the sealing stability. The transparent shell and the surrounding area of the liquid crystal display are better sealed before the glue injection process, thereby improving the yield rate and solving the above-mentioned technical problems existing in the background technology.

[0004] The technical solution of the utility model is:

[0005] A novel transparent shell structure for an ultrasonic water meter includes a transparent shell and a liquid crystal display (LCD). The transparent shell is provided with a mounting recess for the LCD, a viewing window is provided at the bottom center of the mounting recess, and a window protection frame is provided around the viewing window. The window protection frame is a convex ridge surrounding the viewing window. The space between the window protection frame and the sidewalls of the mounting recess forms a glue injection area, into which silicone is injected by a glue injection machine. The LCD is placed in the mounting recess and aligned with the position of the window. The space between the LCD and the sidewalls of the mounting recess forms a glue filling area, into which sealant is filled to seal the LCD. The present invention enhances the stability of the glue filling area by providing a window protection frame around the viewing window and injecting silicone by a glue injection machine, replacing the manual application of a sealing sponge. Silicone has a higher viscosity than sealant. After the glue injection machine injects silicone into the glue filling area and then places the LCD, sealant can be directly poured into the glue filling area, effectively preventing glue overflow from the window and improving the yield rate.

[0006] The LCD display is provided with a main board, and a plurality of limiting protrusions are provided on the upper side wall of the mounting groove. The board surface of the main board is placed in the mounting groove, and the limiting protrusions constrain the horizontal position of the main board. After the LCD display is attached to the window protection frame, the limiting protrusions constrain the LCD display to face the window protection frame.

[0007] A mainboard fixing buckle is provided on the side of the limiting protrusion. After the mainboard surface is placed in, the mainboard fixing buckle limits the surface, so that the liquid crystal display and the window protection frame are tightly fitted.

[0008] The space between the bottom of the mainboard and the bottom of the transparent shell is a glue filling area.

[0009] The utility model can realize automatic glue injection of the transparent shell because the glue injection area is provided.

[0010] The utility model has the following beneficial effects: simple structure, convenient assembly, automatic assembly, improved assembly efficiency and stability, effective prevention of glue overflow in the window, and improved yield. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below through embodiments with reference to the accompanying drawings.

[0016] A novel transparent housing structure for an ultrasonic water meter comprises a transparent housing 8 and a liquid crystal display 6. The transparent housing 8 is provided with a mounting recess 10 for the liquid crystal display 6. A viewing window 9 is provided at the bottom center of the mounting recess 10. A window protection frame 1 is provided around the viewing window 9. The window protection frame 1 is a convex ridge surrounding the viewing window 9. The space between the window protection frame 1 and the sidewalls of the mounting recess 10 forms a glue injection area 2. A glue injection machine injects silica gel B into the glue injection area 2. The liquid crystal display 6 is placed in the mounting recess 10 and aligned with the position of the window 9. The space between the liquid crystal display 6 and the sidewalls of the mounting recess 10 forms a glue filling area 3. The glue filling area 3 is filled with sealant to seal the liquid crystal display 6. The present invention provides a glue filling area 2 by providing the window protection frame 1 around the viewing window 9. The glue filling area 2 is then filled with silica gel B by the glue injection machine, replacing the manual application of a sealing sponge. This enhances the stability of the glue filling. The viscosity of silica gel B is higher than that of sealant. After the glue injection machine injects silica gel B into the glue filling area 2 and then places the liquid crystal display 6, the sealant can be directly poured into the glue filling area 3. This effectively prevents glue overflow from the window and improves the yield rate.

[0017] The LCD display 6 is provided with a mainboard A, and a plurality of limiting protrusions 5 are provided on the upper side wall of the mounting groove 10. The board surface 7 of the mainboard A is placed in the mounting groove 10, and the limiting protrusions 5 constrain the horizontal position of the mainboard A. After the LCD display 6 is attached to the window protection frame 1, the LCD display 6 is constrained by the limiting protrusions 5 so as to face the window protection frame 1.

[0018] The side of the limiting protrusion 5 is provided with a mainboard fixing buckle 4. After the board surface 7 of the mainboard A is placed in, the mainboard fixing buckle 4 limits the board surface 7, so that the liquid crystal display 6 and the window protection frame 1 are tightly fitted.

[0019] The mainboard fixing buckle 4 is made of elastic material, and the top of the mainboard fixing buckle 4 is tilted to facilitate the board surface 7 of the mainboard A to be clamped under the mainboard fixing buckle 4.

[0020] Each side wall of the mounting groove 10 is provided with two limiting protrusions 5 , which are vertically arranged. The side surfaces of the limiting protrusions 5 on the two side walls are provided with mainboard fixing buckles 4 .

[0021] The space between the bottom of the board surface 7 of the mainboard A and the bottom of the transparent shell 8 is the glue filling area 3.

[0022] The utility model can realize automatic glue injection of the transparent shell due to the provision of the glue injection area 2.

[0023] The thickness from the board surface 7 of the mainboard A to the liquid crystal display 6 is interference-fitted with the distance from the transparent shell window protection frame 1 to the mainboard fixing buckle 4, so that the liquid crystal display 6 and the window protection frame 1 fit tightly.

[0024] The assembly process is as follows:

[0025] ① Place the open end of the mounting groove 10 at the bottom of the transparent housing 8 horizontally upwards, and use a glue injection machine to inject silicone rubber B into the glue injection area 2, so that the silicone rubber B completely surrounds the window protection frame 1;

[0026] ② Place the LCD display 6 side of the motherboard A downward, facing the mounting groove 10 at the bottom of the transparent housing 8, and install it downward along the limiting protrusions 5 on the side wall. The LCD display 6 is attached to the transparent housing window protection frame 1. Press the motherboard downward until the board surface 7 of the motherboard A is fully engaged with the motherboard fixing clips 4. At this time, the silicone rubber B is squeezed by the transparent housing, window protection frame 1 and LCD display 6, completely sealing the window protection frame 1.

[0027] ③ Using a glue injection machine to inject sealant into the glue injection area 3, the sealant injected into the glue injection area 3 seals the liquid crystal display 6, effectively preventing glue from overflowing in the window and improving the yield rate.
