Description

Technical Field

[0001] This utility model belongs to the field of safety equipment technology, and specifically relates to a pressure head-up display device. Background Technology

[0002] A head-up display (HUD) is an important safety device, commonly used in personal protective equipment such as positive-pressure breathing apparatus for fire fighting. It receives wireless signals transmitted by a transmitter and displays the remaining air pressure to alert the user.

[0003] Conventional pressure head-up displays are snapped onto the mask via a snap-fit ​​structure and have several LEDs within the user's line of sight to indicate the remaining oxygen. To reduce the weight of the display and the burden on the user when carrying it, the casing is often made of non-metallic composite materials. However, composite materials will age over time and may break during compression installation. Therefore, it is necessary to design an installation structure to reduce casing breakage. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a pressure head-up display device that is easy to assemble and disassemble, prevents breakage, and enables rapid search and rescue.

[0005] The objective of this utility model can be achieved through the following technical solution: A pressure head-up display device, characterized in that it includes a housing with a power supply compartment, a display unit on the top of the housing, a plurality of display LEDs on the display unit, a snap-fit ​​ring on the housing, and an expansion joint at the bottom of the snap-fit ​​ring, a fitting part and a locking part at the bottom of the snap-fit ​​ring, a protruding locking block on the fitting part, the locking block being positioned in the middle of the locking part, a guide opening groove on the locking block, a locking slider on the locking part, a guide groove on the locking slider, and a press key on both ends of the locking slider.

[0006] In the aforementioned pressure head-up display device, a waterproof groove is provided on the power supply compartment, and two sealing rings are provided in the waterproof groove. A waterproof cover plate is provided on the power supply compartment, and several indicator light strips are evenly distributed on the waterproof cover plate. The waterproof cover plate is embedded between the sealing rings.

[0007] In the aforementioned pressure head-up display device, the power supply compartment is further provided with a locking cover, the housing is provided with several slots, the locking cover is provided with a fixing buckle and an elastic buckle, and the display light strips all protrude from the locking cover plate.

[0008] In the aforementioned pressure head-up display device, the display unit is provided with a fixed cover plate, the display unit and the fixed cover plate are respectively located on both sides of the housing, and the display unit is also provided with control buttons.

[0009] Compared with existing technologies, this pressure head-up display device uses the elasticity of composite materials to control the sliding of the locking block between the locking parts. The compression of the housing facilitates quick assembly and disassembly of the housing. After installation, the locking slider locks the device in place, preventing the installation from falling off due to the sliding of the locking block. Two sealing rings are set in the waterproof groove to compress the waterproof cover plate and increase the waterproof performance. The indicator light bar can display the battery level when the device is turned on and can also control the strobe light, making the user easier to spot during rescue operations.
