[0001] This utility model relates to the field of fire warning. More specifically, this utility model relates to a fire guidance system. Background Technology
[0002] Fire guidance systems are warning devices installed in public places. In the event of a fire, these devices provide warnings to the public and staff on the ground or walls, or indicate escape routes. These devices are widely used in shopping malls, hotels, and other similar locations.
[0003] Existing fire guidance systems often project escape directions or escape signs onto walls or the ground using simple projection mechanisms. However, these simple projection mechanisms cannot be adjusted in terms of projection angle and position after installation. As a result, they may be affected by site factors during use, making it impossible to project the required image clearly and thus affecting the normal operation of the device. Utility Model Content

[0020] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.
[0021] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] like Figure 1-5As shown, the present invention proposes a fire guidance system, including a projection mechanism, a mounting shell, a sliding block, and a mounting component. The mounting shell is connected to the non-projection end of the projection mechanism, and its top has a first opening and a second opening that are interconnected. The sliding block performs a combined sliding and rotating motion within the opening through a connecting component. The mounting component is located above the mounting shell and connected to the sliding block, and can move with the sliding block to a position parallel to the axis of the second opening.
[0023] The projection mechanism refers to the optical components that generate and project escape signs. Specifically, digital micromirror devices combined with LED light sources can be used to generate and project images.
[0024] Through the composite design of interconnected tracks of the first and second openings, the projection mechanism gains two degrees of freedom of movement. The continuous movement of the sliding block enables real-time dynamic adjustment. Especially when dealing with tilted projection surfaces, this device can complete position translation and angle compensation to ensure that the escape sign always maintains a complete projection. While maintaining structural stability, this device achieves non-disassembly projection parameter adjustment, significantly improving the reliability and adaptability of emergency escape guidance.
[0025] This application further proposes a connecting component including a transmission block, a first groove on the inner wall of the first opening, a second groove communicating with the first groove on the inner wall of the second opening, the transmission block being slidably disposed in the first groove and slidingly attached to its inner wall, the transmission block being slidably disposed in the second groove and slidingly attached to its inner wall, the transmission block being rotatably disposed with the sliding block through a connecting unit, and the transmission block being limited to the mounting shell by a limiting unit.
[0026] When the transmission block slides horizontally along the first groove, it drives the sliding block to move laterally. When it is necessary to adjust the projection direction, the transmission block can slide vertically along the second groove. At this time, the sliding block rotates through the connecting unit to change the tilt angle of the mounting component. Through the connection design between the first groove and the second groove, the transmission block has the ability to slide horizontally and vertically in both directions. At the same time, combined with the connecting unit, the mounting component can automatically adjust the angle during the movement, which solves the problem of the single projection angle caused by the structural limitations of traditional devices.
[0027] This application further proposes a connecting unit including a mounting shaft, a first through hole on a sliding block, and a transmission block connected to the horizontally arranged mounting shaft at one end facing the sliding block. The mounting shaft is rotatably disposed within the first through hole.
[0028] Specifically, the transmission block is connected to the sliding block through the mounting shaft to form a rotating pair. When an external force is applied to the mounting assembly, the mounting shaft rotates circumferentially in the first through hole as the sliding block moves along the opening trajectory of the mounting shell. This rotational freedom allows the mounting assembly to adjust the pitch angle of the projection mechanism according to the actual installation environment while following the translation of the sliding block.
[0029] This application further includes a slide rod, a limiting rod, a limiting plate, and a spring. The slide block is provided with a second through hole that communicates with the first through hole. The slide rod is slidably disposed in the second through hole. One end of the slide rod is connected to the limiting rod, which can be moved into the first through hole. The other end of the slide rod extends out of the second through hole and is connected to the limiting plate. The spring is coaxially sleeved on the other end of the slide rod. Both ends of the spring are respectively connected to the slide block and the limiting plate. Multiple third grooves for the limiting rod to extend into are evenly distributed along the axial direction on the mounting shaft. The limiting rod and the inner wall of the third groove are slidably fitted together.
[0030] Specifically, when the angle of the installation component needs to be adjusted, the operator pulls the limiting plate outward to make the slide rod drive the limiting rod away from the third groove. At this time, the sliding block can rotate freely around the installation axis. When the target angle is reached, the limiting plate is released to make the spring push the slide rod to reset. The limiting rod automatically inserts into the corresponding third groove to complete the positioning. Thus, through the cooperation of the spring and the limiting rod with the groove, rapid angle adjustment and reliable positioning can be achieved. Multiple adjustment levels can be completed without tools during the operation.
[0031] This application further proposes a limiting unit including a first bolt, a first notch on the mounting shell communicating with a first groove, a second notch on the mounting shell communicating with a second groove, the first notch and the second notch communicating with each other, a first threaded through hole and a second threaded through hole respectively on both ends of the transmission block facing the first notch and the second notch, the first threaded through hole and the second threaded through hole communicating with each other, a plurality of third through holes corresponding to the first threaded through holes are arranged side by side at intervals on the inner wall of the first groove, a plurality of fourth through holes corresponding to the second threaded through holes are arranged side by side on the inner wall of the second groove, the first bolt can be threaded through the first threaded through hole and extended into any of the third through holes, and the first bolt can be threaded through the second threaded through hole and extended into any of the fourth through holes.
[0032] Specifically, when the transmission block slides along the first groove, the first bolt can pass through the first threaded through hole and be inserted into the corresponding third through hole. At this time, the transmission block is restricted to a specific position within the first groove. When the transmission block slides to the second groove, the first bolt can pass through the second threaded through hole and be inserted into the corresponding fourth through hole. At this time, the transmission block is restricted to a specific position within the second groove. This effectively limits the position of the transmission block, thereby completing the limitation of the sliding block's position.
[0033] This application further proposes an installation assembly including a connecting rod and a mounting plate, one end of the connecting rod being connected to a sliding block, and the other end of the connecting rod being coaxially arranged with and rotatably connected to the mounting plate.
[0034] The device is installed on a wall or ceiling using a mounting plate. Specifically, it can be installed with screws. A threaded blind hole is made in the wall or ceiling, and a mounting hole is made in the mounting plate. The screw is passed through the mounting hole and inserted into the threaded blind hole to complete the installation. The connecting rod effectively connects the projection mechanism and the mounting housing. The connecting rod and the mounting plate are rotatable, allowing the guide mechanism and the mounting housing to rotate, thus rotating the projection position of the projection mechanism and further expanding the projection range of the device.
[0035] This application further proposes a technical solution in which a connecting rod is coaxially connected to a fixing plate and placed below the mounting plate, a third threaded through hole is opened on the fixing plate, and a second bolt is threadedly installed in the third threaded through hole and can be moved to abut against the mounting plate.
[0036] When the angle of the connecting rod needs to be adjusted, the second bolt can be moved axially along the third threaded through hole until its end no longer contacts the mounting plate, so that the connecting rod can be moved easily. When the second bolt is tightened, the mounting plate is pressed against the fixed plate, thereby fixing the angle of the connecting rod and improving the stability of the device during use.
[0037] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and embodiments shown and described herein.
