Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically a fire emergency evacuation indication structure. Background Technology

[0002] Fire escape signs are the core guidance components of a building's emergency evacuation system, and their reliability is directly related to the safety of people in emergency situations. According to national standards such as the "Technical Standard for Fire Emergency Lighting and Evacuation Guidance Systems" (GB 51309-2018), signs must have functions such as continuous guidance, emergency power supply, and fault self-diagnosis, and must meet the corresponding power supply duration and brightness standards. Currently, most escape signs on the market are wall-mounted or recessed. As building scale expands, the density of sign placement increases significantly, but their maintenance design has obvious flaws, leading to high maintenance difficulty and costs. This directly reduces staff's willingness to perform maintenance and ultimately increases the risk of "failure in emergencies." The maintenance problems of existing signs mainly manifest in the following ways: Component replacement is complex. Most are integrated packages, with core components fixed by welding or multiple sets of screws. Replacement requires disassembling the outer shell, cutting wires, and rewiring. Recessed signs may even require damaging the wall, further exacerbating maintenance resistance. Manual inspection is arduous, relying on point-by-point inspection and recording. In large buildings, this is labor-intensive and prone to oversight. Fault information requires manual summarization, leading to delayed response and low staff motivation for proactive maintenance. Installation and maintenance are poorly compatible. Wall-mounted signs have wiring terminals hidden on the back, requiring disassembly for maintenance. Recessed signs have limited maintenance space, making tool operation difficult, and frequent plugging and unplugging of wires can cause poor contact, further discouraging staff from proactively maintaining them. Due to the aforementioned maintenance difficulties, staff often reduce the frequency of inspections or even omit necessary maintenance, leading to the accumulation of sign malfunctions, which in turn affects evacuation safety in emergency situations due to the failure of the signs.

[0003] In view of this, a fire emergency evacuation guidance structure is provided to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to provide a fire emergency evacuation indication structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a fire emergency evacuation indication structure, including a mounting base, an internal receiving groove, and an integrally formed mounting ear on the edge of the mounting base. In its initial state, a fire display sign body is placed inside the receiving groove. An integrally formed snap-fit ​​groove is formed on the edge of the fire display sign body. A mating assembly that matches the snap-fit ​​groove is installed on the inner wall edge of the receiving groove of the mounting base. The specific number of mounting ears is four, and the four mounting ears are arranged symmetrically.

[0006] Furthermore, a notch is provided at the top front side of the outer wall of the mounting base, and a lifting frame is fixedly installed on the outer wall of the fire protection display board body at the notch.

[0007] Furthermore, a glass display window is fixedly installed on the front side of the outer wall of the mounting base.

[0008] Furthermore, the docking assembly includes a hinge shaft, which is mounted on the side wall of the mounting base. A rotatable snap-fit ​​block is fitted on the outer wall of the hinge shaft. A square groove is formed at the top of the side wall of the receiving groove. The docking assembly is located inside the square groove. A return spring is fixedly connected between the bottom end of the snap-fit ​​block and the bottom of the inner wall of the square groove.

[0009] Furthermore, a limiting groove is formed on the side wall of the square groove, and a movable limiting block is provided inside the limiting groove. A pressing block is fixedly connected to one side of the limiting block, and the pressing block is located above the snap-fit ​​block.

[0010] Furthermore, the snap-fit ​​block is specifically "L" shaped, with an arc-shaped snap-fit ​​element integrally formed at its top. In the initial state, the arc-shaped snap-fit ​​element is located inside the snap-fit ​​groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By setting up an installation base and a fire safety display board body, and by creating a receiving groove inside the installation base and fixing mounting ears at the edge of the installation base, users can install the installation base and the fire safety display board body separately. When the fire safety display board body needs to be inspected and maintained, it can be quickly disassembled through the cooperation of the docking components and the snap-fit ​​groove. At the same time, the installation base and the fire safety display board body will not easily separate due to the snap-fit ​​action of the docking components and the snap-fit ​​groove, so that the fire safety display board body can be reliably inspected and maintained.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 See Figures 1-4 A fire emergency evacuation indication structure includes a mounting base 1, an internal receiving groove 6, and an integrally formed mounting ear 4 at the edge of the mounting base 1. In the initial state, a fire display sign body 2 is placed inside the receiving groove 6. An integrally formed snap-fit ​​groove 8 is formed at the edge of the fire display sign body 2. A docking component 7 that is compatible with the snap-fit ​​groove 8 is installed at the inner edge of the receiving groove 6 of the mounting base 1. The specific number of mounting ears 4 is four, and the four mounting ears 4 are arranged symmetrically.

[0016] A notch is provided at the top front of the outer wall of the mounting base 1, and a lifting frame 3 is fixedly installed on the outer wall of the fire safety display board body 2 at the notch. By setting a notch and installing a lifting frame 3 at the corresponding position of the fire safety display board body 2, users can more easily remove the fire safety display board body 2 without any obstruction.

[0017] The docking assembly 7 includes a hinge shaft 71, which is mounted on the side wall of the mounting base 1. A rotatable snap-fit ​​block 72 is fitted on the outer wall of the hinge shaft 71. A square groove is opened at the top of the side wall of the receiving groove 6. The docking assembly 7 is located inside the square groove. A return spring 73 is fixedly connected between the bottom end of the snap-fit ​​block 72 and the bottom of the inner wall of the square groove.

[0018] When the user contacts the locking block 72 through the locking slot 8, the locking block 72 can compress the return spring, so that the locking slot 8 can be embedded into one side of the locking block 72, so that the entire body of the fire display board 2 is restricted by the locking slot 8 and the docking component 7 and will not be detached from the device without human intervention.

[0019] By setting a reset spring 73 between the snap-fit ​​block 72 and the square groove, the snap-fit ​​block 72 can be automatically reset by the elastic force of the reset spring 73 after one end is pressed down.

[0020] A limiting groove 75 is provided on the side wall of the square groove. A movable limiting block 76 is provided inside the limiting groove 75. A pressing block 74 is fixedly connected to one side of the limiting block 76. The pressing block 74 is located above the snap-fit ​​block 72.

[0021] By setting the limiting groove 75 and the limiting block 76, the movement of the pressing block 74 is restricted, and it can only move in a predetermined direction. However, by setting the pressing block 74 above the locking block 72, the user can press down on the pressing block 74 to make the locking block 72 rotate around the hinge axis 71, thereby allowing one end of the locking block 72 to be controlled to move out of the locking groove 8.

[0022] It should be noted that the snap-fit ​​block 72 is specifically "L" shaped, with an arc-shaped snap-fit ​​piece integrally formed at its top. In the initial state, the arc-shaped snap-fit ​​piece is located inside the snap-fit ​​groove 8.

[0023] In addition, a glass display window 5 is fixedly installed on the front side of the outer wall of the mounting base 1.

[0024] In practice, conventional emergency evacuation signs are usually fixed in emergency passages with bolts. However, their maintenance design has obvious defects, which makes maintenance difficult and costly. This reduces the willingness of relevant personnel to carry out maintenance, affecting the maintenance of emergency evacuation signs and making them prone to malfunction when needed for emergency use.

[0025] In this practical application, the fire safety display board body 2 is directly embedded in the receiving groove 6 opened in the mounting base 1. When the staff needs to inspect the fire safety display board body 2, they only need to press down the pressing button 74 so that the pressing button 74 abuts against one end of the locking block 72, causing the locking block 72 to rotate around the hinge shaft 71. After the locking block 72 rotates, one end of it will disengage from the inside of the locking groove 8, so that the fire safety display board body 2 and the locking groove 8 are no longer restricted by the docking component 7. The user can easily take it out from the receiving groove 6 for inspection.

[0026] When putting the fire display board body 2 back, press the pressing block 74, align the snap-fit ​​groove 8 with the docking component 7 away from the pressing block 71, and rotate it around the hinge axis 71. After the snap-fit ​​groove 8 moves to the predetermined position, release the pressing block 74. At this time, the snap-fit ​​block 72 can be reset under the elastic force of the return spring 73, so that the mounting base 1 and the fire display board body 2 can be snapped together again.

[0027] By setting up an installation base frame 1 and a fire safety display board body 2, and by opening a receiving groove 6 inside the installation base frame 1, and fixing the installation ears 4 at the edge of the installation base frame 1, the user can install the installation base frame 1 and the fire safety display board body 2 separately. When the fire safety display board body 2 needs to be inspected and maintained, it can be quickly disassembled through the cooperation of the docking component 7 and the snap-fit ​​groove 8. At the same time, under the snap-fit ​​action of the docking component 7 and the snap-fit ​​groove 8, the installation base frame 1 and the fire safety display board body 2 will not easily separate, so that the fire safety display board body 2 can be reliably inspected and maintained.

[0028] Working principle: Conventional emergency evacuation signs are usually fixed in emergency passages with bolts, but their maintenance design has obvious defects, resulting in high maintenance difficulty and cost. This reduces the willingness of relevant personnel to carry out maintenance, affecting the maintenance of emergency evacuation signs and making them prone to failure when needed for emergency use.

[0029] In this practical application, the fire safety display board body 2 is directly embedded in the receiving groove 6 opened in the mounting base 1. When the staff needs to inspect the fire safety display board body 2, they only need to press down the pressing button 74 so that the pressing button 74 abuts against one end of the locking block 72, causing the locking block 72 to rotate around the hinge shaft 71. After the locking block 72 rotates, one end of it will disengage from the inside of the locking groove 8, so that the fire safety display board body 2 and the locking groove 8 are no longer restricted by the docking component 7. The user can easily take it out from the receiving groove 6 for inspection.

[0030] When the fire display board body 2 is put back, press the pressing block 74 and rotate the locking block 72 around the hinge shaft 71 to align the locking groove 8 with the side of the docking assembly 7 away from the pressing block 74. After the locking groove 8 moves to the predetermined position, release the pressing block 74. At this time, the locking block 72 can be reset under the elastic force of the return spring 73, so that the mounting base 1 and the fire display board body 2 can be locked together again.

[0031] By setting up an installation base frame 1 and a fire safety display board body 2, and by opening a receiving groove 6 inside the installation base frame 1, and fixing the installation ears 4 at the edge of the installation base frame 1, the user can install the installation base frame 1 and the fire safety display board body 2 separately. When the fire safety display board body 2 needs to be inspected and maintained, it can be quickly disassembled through the cooperation of the docking component 7 and the snap-fit ​​groove 8. At the same time, under the snap-fit ​​action of the docking component 7 and the snap-fit ​​groove 8, the installation base frame 1 and the fire safety display board body 2 will not easily separate, so that the fire safety display board body 2 can be reliably inspected and maintained.
