Description

Technical Field

[0001] This utility model relates to the field of digital water level display technology, specifically a digital water level display device. Background Technology

[0002] Water level display devices are commonly used to monitor liquid levels, such as in reservoirs, water towers, water tanks, or industrial containers; they are also known as water level measuring instruments.

[0003] For example, the Chinese authorized patent with publication number CN220960218U (a water level measuring instrument) includes a water level measuring instrument body, which includes a measuring display host, a support base, a measuring wire, and a measuring probe. The measuring display host is located at the top of the support base, the measuring wire is snapped onto the end of the measuring display host, and the measuring probe is located at the end of the measuring wire. By designing a storage and protection mechanism, after the water level measuring instrument body is used for water level measurement, the measuring wire can be wound around the outer surface of the winding reel, and the end is snapped into the inside of the retainer for fixation. It is also convenient to use the winding reel to wind up the measuring wire. After winding, the handwheel drives the lead screw to rotate in place inside the groove. When the lead screw is rotated, the moving head moves, and when the moving head moves, the winding reel moves and closes inside the support base. It is also convenient to use the winding reel and the measuring wire to be closed and protected inside the support base after winding.

[0004] However, most existing digital water level display devices use bolts or hot-melt processes to fix the casing, which makes disassembly and repair inconvenient when internal parts are damaged, and may even require damage to the casing, resulting in high repair costs, high repair difficulty, and inconvenience. Therefore, this does not meet the current needs, and we propose a digital water level display device. Utility Model Content

[0005] The purpose of this utility model is to provide a water level digital display device to solve the problems mentioned in the background art, which are that the housing of most existing water level digital display devices is fixed by bolts or by hot melting process, which makes it inconvenient to disassemble and repair internal parts when they are damaged, and may even require damage to the housing, resulting in high repair costs, high repair difficulty and inconvenience.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a digital water level display device, comprising: a display body, a water level probe disposed below the display body, a wire disposed between the water level probe and the display body, the display body comprising a control panel and a first housing, wherein the first housing is located at the rear end of one side of the control panel, and a second housing is disposed at the rear end of the other side of the control panel, wherein both the first housing and the second housing are provided with cavities inside. A connecting plate is provided on one side surface of the first housing, and a sealing sleeve is provided on the outside of the connecting plate. A connecting slot is provided on one side surface of the second housing, and the connecting plate is inserted into the connecting slot. A first connecting post is provided on the inner wall of the cavity of the first housing, and a second connecting post is provided on the inner wall of the cavity of the second housing. Both the first and second connecting posts have through grooves that penetrate the first housing, the second housing, the first connecting post, and the second connecting post. A bolt post is inserted into the through groove, and one end of the bolt post is threaded with a threaded seat. A sleeve groove is provided on the rear surface of the first and second housings, and the sleeve groove penetrates the first and second housings. A rubber ring seat is heat-fused to the inner wall of the sleeve groove of the first housing. A probe fixing seat is provided at the upper end of the first housing, and fixing screws are provided at both ends of the probe fixing seat. The probe fixing seat is threadedly fixed to the first housing by the fixing screws.

[0007] Preferably, both the first housing and the second housing are provided with a limiting moving seat on the side near the control panel, the rear surface of the control panel is provided with a limiting moving groove, and the limiting moving seat moves along the limiting moving groove.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] (1) This utility model provides a limiting moving seat on the rear surface of both the first housing and the second housing, and a limiting moving groove on the rear surface of the control panel. When the first housing and the second housing are installed, the limiting moving seat moves along the limiting moving groove to connect the first housing and the second housing with the control panel. Both the limiting moving seat and the limiting moving groove are T-shaped structures, which improves the connection stability and prevents them from falling off. The connecting plate is inserted into the connecting slot to improve the connection stability of the first housing and the second housing. The sealing sleeve improves the connection sealing performance and prevents water leakage. Finally, the bolt column is used for reinforcement. When disassembling, only the threaded seat needs to be removed to quickly disassemble the first housing and the second housing, which improves the convenience of disassembly. This solves the problem that most of the housings of existing water level digital display devices are fixed by bolts or by hot melt process, which leads to damage to internal parts. When repairing, disassembly and repair are inconvenient and may even require damage to the housing, resulting in high repair costs, high repair difficulty, and inconvenience.

[0010] (2) By setting a probe fixing seat at the upper end of the first housing, the probe fixing seat is threaded to the first housing by fixing screws. The water level probe is fixed by the probe fixing seat, which is convenient to carry. The probe fixing seat is also detachable and easy to replace. Attached Figure Description
