Description

Technical Field

[0001] This utility model belongs to the technical field of very early fire warning devices, specifically relating to a sliding cover opening device for very early fire warning devices. Background Technology

[0002] Early warning fire (ELF) devices are equipment that can quickly identify the source of a fire and issue an early warning signal by detecting changes in smoke, temperature, and gases in the early stages of a fire. They can detect fire hazards much earlier than traditional fire alarm systems, thus buying more time for evacuation and firefighting, and reducing fire losses. ELF devices typically involve aspirating fire alarm products.

[0003] When current aspirating fire alarm products are installed on the wall, it is necessary to facilitate the opening of the cover for wiring and routing at the installation site. However, most products on the market use mechanical screws to open the cover, which leaves screw holes or screw marks on the visible surface of the cover. The screws are also easy to fall off and be lost on site, affecting the appearance. At the same time, the operation of opening or closing the cover with screws is cumbersome and not conducive to the disassembly of the equipment on the wall. Utility Model Content

[0004] To address the aforementioned shortcomings, this utility model provides a sliding cover opening device for a very early fire warning device. This utility model enables rapid opening and closing of the very early fire warning device on the wall, while the device as a whole has no screw holes or other openings, ensuring a clean and aesthetically pleasing appearance. This utility model offers stable unlocking without the risk of unlocking failure. This utility model also allows for quick replacement of parts, facilitating subsequent maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sliding cover device for an early fire warning system includes a lower shell and an upper cover. Multiple sliding grooves are evenly distributed around the sidewalls of the lower shell, and sliders are vertically slidably connected to these grooves. Multiple upper cover latches and multiple lower shell latches are fixedly arranged around the inner perimeter of the upper cover and the lower shell, respectively, with the upper cover latches engaging with their corresponding lower shell latches. The sliders are connected to a folding push plate inside the lower shell, with one end of the folding push plate located between the lower shell latches and the upper cover latches. A sliding hole is formed on the folding push plate, and a sliding rod is fixedly arranged inside the lower shell, slidably connected to the sliding hole. A compression spring is sleeved on the sliding rod, located inside the lower shell and between the folding push plate. An inclined push block is also fixedly arranged on the folding push plate, positioned below the upper cover latches. Spring mechanisms are fixedly installed at the four corners of the inside of the upper cover, and the spring mechanisms are in movable contact with the inside of the lower shell.

[0006] Furthermore, the folding push plate includes a first vertical plate, a first horizontal plate, and a second vertical plate that are fixedly connected in sequence; the inclined push block is fixedly disposed in the middle of the connection between the first horizontal plate and the second vertical plate, and the sliding hole is located on both sides of the first horizontal plate; the end of the second vertical plate is located between the lower shell buckle block and the upper cover buckle block.

[0007] Furthermore, a first vertical groove is formed through the groove, and a force-generating rod is fixedly provided on the inner side wall of the slider; a force-receiving hole is correspondingly formed on the first vertical plate, and the force-generating rod passes through the first vertical groove and extends into the force-receiving hole.

[0008] Furthermore, a second vertical groove is provided through the groove, and a slider buckle is fixedly provided on the inner side wall of the slider; the first vertical plate is provided with a buckle hole, and the slider buckle passes through the second vertical groove and is engaged with the buckle hole.

[0009] Furthermore, a first protrusion is fixedly provided at the end of the lower shell fastener, and a second protrusion is fixedly provided on the side of the upper cover fastener near the end of the lower shell fastener; when the upper cover fastener and the lower shell fastener are fastened together, there is a gap between the upper cover fastener and the lower shell fastener.

[0010] Furthermore, the outer wall of the slider is fixedly provided with a protrusion.

[0011] Furthermore, a bottom cover is fixedly installed at the bottom of the lower shell.

[0012] Furthermore, the slide bar has two rods.

[0013] Furthermore, the locking hole has two holes.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model presses the top cover down so that the top cover buckle is engaged with the corresponding bottom cover buckle of the bottom shell, and the two are tightly engaged. During this process, the spring mechanism at the contact feature between the top cover and the bottom shell is compressed and stores energy. When the top cover is to be opened, the external slider of the device is slid upward, and the slider drives the internal folding push plate of the device to squeeze the top cover buckle of the top cover to deform, so that it is disengaged from the bottom cover buckle of the bottom shell. At this time, the spring mechanism at the contact feature between the top cover and the bottom shell releases energy and pushes the top cover out, so that the top cover can be opened quickly. This allows for the quick opening and closing of the very early fire warning device on the wall, while the device as a whole has no screw holes or other openings, ensuring that the device is clean and beautiful.

[0015] (2) Through the structural design of the inclined push block and its cooperation with the second vertical plate, this utility model can quickly unlock the lower shell buckle and the upper cover buckle by pushing the inclined push block when the folding push plate is moved up. At the same time, the end of the second vertical plate is always located between the lower shell buckle and the upper cover buckle, so that the problem of unlocking failure will not occur. Furthermore, the automatic reset of the folding push plate can be achieved through the cooperation of the compression spring, which is convenient for the next opening and closing operation.

[0016] (3) Through the structural design of the slider buckle and the force rod, the dual positioning of the force rod and the slider buckle makes it easy to adjust and operate stably. It is also easy to disassemble. The parts can be quickly replaced by contacting and buckling the slider buckle, which is convenient for subsequent maintenance. Attached Figure Description
