Description

Technical Field

[0001] This utility model relates to the field of water supply control technology, specifically to a water supply controller. Background Technology

[0002] The water supply and sanitation system is an important component of the train. The equipment in the water supply and sanitation system is mainly a facility that provides sanitation services for passengers and train crew. The water supply and sanitation system generally includes a water purification system and a waste disposal system, which are usually controlled by separate controllers.

[0003] Most water supply controllers are equipped with displays to show control programs and facilitate operation. Currently, the displays of water supply controllers are generally fixed directly to the edge of the controller housing with four M3 screws. When the controller is installed in a control cabinet or a distribution box near the water pump, the temperature fluctuation range inside the distribution box is 30℃-60℃, which causes the housing to undergo thermal expansion and contraction deformation of 0.5-1mm. This deformation is directly transmitted to the display screen frame, easily causing cracks in the display screen glass or poor contact of the ribbon cable (touch screen malfunction). Although some existing technologies have attempted to use a single bracket to fix the display screen, the bracket is rigidly connected to the housing (without a buffer gap), which still cannot solve the problem of deformation transmission. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: A water supply controller includes a back panel, on the front of which a housing is mounted by screws. The housing has an opening on the upper left side of its front, and a touch screen is mounted inside the housing via a mounting bracket at the opening. A socket panel is mounted on the right side of the housing's front by screws.

[0005] Furthermore, the mounting bracket includes two brackets located on the left and right sides of the touch screen. The touch screen is mounted to the brackets with screws. The upper and lower ends of the brackets are integrally formed and fixed with fixing ears. An upper fixing bracket is installed in the housing above the bracket with screws, and a lower fixing bracket is installed in the housing below the bracket with screws. The upper and lower fixing brackets are respectively connected to the fixing ears at the upper and lower ends of the brackets. A deformation buffer gap of 1-2mm is reserved between the upper and lower fixing brackets and the brackets.

[0006] Furthermore, a connector is installed between the upper fixed frame and the upper fixed ear of the frame plate. The connector is connected to the upper fixed frame and the fixed ear by screws. A connector is installed between the lower fixed frame and the lower fixed ear of the frame plate. The connector is connected to the lower fixed frame and the fixed ear by screws. The assembly gap between the fixed ear and the lower fixed frame and the upper fixed frame is controlled at 0.5-1mm.

[0007] Furthermore, the back plate above the housing is made of metal, and a circuit board is mounted on the back plate by M3 screws, with terminal blocks integrated and mounted on the circuit board by solder.

[0008] The beneficial effects of this utility model are as follows: 1. This utility model uses a mounting bracket to connect the touch screen and the housing. The thermal expansion and contraction deformation of the housing needs to act on the mounting bracket first, and then on the touch screen. With the mounting bracket and the deformation buffer gap, the lateral and longitudinal stresses generated by the thermal expansion and contraction of the housing are buffered, reducing the possibility of damage to the touch screen caused by the deformation of the housing.

[0009] 2. The external terminal block of this utility model facilitates wiring and subsequent disconnection. Attached Figure Description
