[0027] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. If a relative arrangement, numerical expression, and numerical values of components and steps set forth in these embodiments are not specifically described, the scope of the present application is not limited to them.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way limiting to the scope of the application or its applications or uses.

[0029] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, the techniques, methods, and devices are sufficiently described in the disclosure.

[0030] In all examples shown and discussed herein, any specific value should be interpreted as merely illustrative and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0031] As Figures 1-7 shown, a quick-mounting protective structure of a smoke sensor includes a smoke generator body 1 and a mounting bracket 2 fixedly mounted on a wall, and the smoke generator body 1 is fixedly mounted with a protective ring 17 for anti-skid.

[0032] Here, the protective ring 17 is arranged around the middle region of the smoke generator body 1, and the surface thereof is provided with anti-skid lines, which facilitates an installer to hold the body for dismounting operation, avoids the body from falling and being damaged due to hand slipping, and fills the gap with the mounting structure after the body is mounted in place, thereby reducing the entry of external dust from the gap into the interior.

[0033] Further, the protective ring 17 is made of elastic rubber material and has certain buffering performance, which can absorb the influence of environmental vibration on the smoke generator body 1, avoid loosening of internal electronic components due to vibration, and improve the running stability of the sensor.

[0034] Further, the smoke generator body 1 is integrally formed with a plurality of extension plates 3, which are arranged in a ring shape at equal intervals on the smoke generator body 1.

[0035] Here, the extension plate 3 serves as a connecting medium between the smoke generator body 1 and the mounting bracket 2, provides a force point for the limiting structure, and realizes precise butt joint of the body and the mounting bracket 2; the integral forming process makes the extension plate 3 and the smoke generator body 1 firmly connected without splicing gaps, avoiding the problems of fracture and falling off after long-term use, and the ring-shaped equidistant arrangement design ensures uniform stress on the body and prevents deviation caused by unbalanced stress after installation.

[0036] Further, the number of extension plates 3 is preferably 3-4, which meets the stability requirement of limiting and does not increase the difficulty of installation operation due to excessive number, and adapts to the quick installation design requirement.

[0037] The mounting bracket 2 is provided with a placing groove 4 adapted to the smoke generator body 1, the placing groove 4 is fixedly connected with a support plate 5 through an elastic member, the smoke generator body 1 is slidably connected in a sliding groove 6 formed in the support plate 5, the upper part of the support plate 5 is fixedly installed with a first magnetic block 10, and the lower part of the smoke generator body 1 is fixedly installed with a second magnetic block 11, when the first magnetic block 10 and the second magnetic block 11 are attracted, the support plate 5 and the smoke generator body 1 abut and form a connection area.

[0038] Here, the placing groove 4 provides a precise accommodation space for the smoke generator body 1, strictly limits the radial position of the body installation, avoids left and right deviation during installation, the sliding groove 6 is formed along the length direction of the support plate 5, provides a clear guide track for the axial sliding of the smoke generator body 1, ensures that the extension plate 3 can be precisely aligned with the limiting sliding groove 12; at the same time, the first magnetic block 10 and the second magnetic block 11 are correspondingly arranged, when the body slides to the pre-installation position along the sliding groove 6, the two magnetic blocks automatically attract to form a temporary connection area, so that the support plate 5 and the smoke generator body 1 preliminarily abut, avoiding accidental slipping of the body during subsequent pressing operation.

[0039] Further, the magnetic temporary fixing does not require additional tools or operations, and cooperates with the guiding effect of the sliding groove 6 to realize a coherent pre-assembly process of "sliding-adsorbing-positioning", greatly reducing the operation difficulty of the installer, especially in high-altitude installation scenarios, the pre-assembly positioning can be completed with one hand, improving the installation safety; at the same time, the formation of the preliminary connection area can make the smoke generator body 1 and the support plate 5 fit more closely, reduce the stress deviation during pressing, and ensure that the magnetic attraction strength of the elastic member and the second magnetic block 11 is accurately adjusted, which can not only provide sufficient adsorption force to realize temporary fixing, but also will not affect the operation of pressing and compressing the spring 9 due to excessive adsorption force. When disassembling, only slight force is needed to separate the two magnetic blocks, taking into account the fixing reliability and operation convenience; and both magnetic blocks are embeddedly installed, with the surface flush with the surface of the support plate 5 and the smoke generator body 1, which does not affect the smooth sliding of the body along the sliding groove 6, and also avoids the problem of dust accumulation or collision damage of protruding structures.

[0044] Here, when installing, press the smoke generator body 1 to compress the spring 9, make the extension plate 3 move down along the limiting sliding groove 12 to the sliding path 14 position, then rotate the body to drive the extension plate 3 to rotate along the sliding path 14, loosen the press after aligning the limiting groove 13, the spring 9 resets to push the body up, make the extension plate 3 clamped into the limiting groove 13 to complete the limiting, the whole process does not need tools, the operation is coherent, and it meets the fast installation demand; the first working area is the pre-positioning area, which is convenient for the installer to align the position, and the second working area is the final fixing area, which ensures that the body is installed in place without deviation.

[0045] Further, the linkage operation of pressing-moving-rotating-loosening is realized by the stretching and sliding of the elastic member and the guiding cooperation of the sliding path 14, realizing the quick locking of mechanical limiting, solving the problem of complicated limiting operation and unstable fixing in the prior art, the plug-in cooperation of the limiting plug 15 and the limiting hole 16 forms secondary fixing after the extension plate 3 is clamped into the groove, and the double limiting structure greatly improves the anti-vibration and anti-collision ability of the body, avoiding loosening after long-term use.

[0046] Further, the sliding path 14 adopts arc transition design, reduces the friction resistance when the extension plate 3 rotates, makes the operation more labor-saving, the slot of the limiting groove 13 is provided with a guide slope, which facilitates the accurate clamping of the extension plate 3, and the elastic force of the spring 9 is accurately adjusted, which not only ensures the operation feeling when pressing, but also provides enough reset force to make the extension plate 3 tightly fit with the groove, while avoiding the installation difficulty caused by too large elastic force.

[0048] Here, the automatic triggering movement of the sliding block 20 is realized by using the principle of magnetic attraction and repulsion, without additional power source, the structure design is ingenious, and the magnetic attraction structure responds quickly, which can start the protection action at the same time when the body is fixed in place by pressing-rotating-loosening operation, realizing the linkage of limiting and protection.

[0049] Further, the guide rails 19 provide precise sliding guidance for the sliding block 20, avoiding deviation and jamming of the sliding block 20, ensuring reliable action of the protection member, and the rectangular slot 18 provides accommodation space for the magnetic attraction structure and the sliding block 20, so that the protection member is integrated in the mounting frame 2, without occupying additional space.
