Description

Technical Field

[0001] The utility model relates to the technical field of fire detection, in particular to a fire detector which is easy to assemble and disassemble. Background Art

[0002] Fire detectors are devices within the automatic fire alarm system that detect fires. They are the system's "sensory organs," monitoring the environment for fires. Once a fire is detected, they convert characteristic physical quantities of fire, such as temperature, smoke, gas, and radiant light intensity, into electrical signals, which then immediately send an alarm signal to the fire alarm controller.

[0003] At present, fire detectors are generally installed on the roof with bolts. When the fire detector is damaged and needs to be disassembled for repair or replacement, the bolts need to be removed one by one, which is a cumbersome disassembly method. At the same time, since the fire detector is directly installed on the roof with bolts, when the bolts are removed, threaded mounting grooves will appear on the roof. If the disassembly is not standardized, the aperture of the threaded mounting groove will increase, which will cause the fire detector to be unstable during the secondary installation. Utility Model Content

[0004] The purpose of the utility model is to provide a fire detector that is easy to disassemble and assemble, so as to solve the problems of inconvenient disassembly and assembly and weak secondary installation of existing fire detectors.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] Example 1

[0035] like Figure 1-5As shown, a fire detector that is easy to disassemble and assemble includes a main body component 100, a limiting component 200 and a fixing component 300. The main body component 100 includes a mounting seat component 101, a fire detector body 102, and a positioning component 103 installed on the fire detector body 102; the limiting component 200 includes a limiting annular groove 201 provided on the mounting seat component 101, and a snap-fit component 202 arranged at the top end of the limiting annular groove 201; the fixing component 300 includes a cavity rod 301 embedded in the mounting seat component 101, a built-in rod 302 and a spring 303 arranged inside the cavity rod 301, and a fixing groove 305 provided on the snap-fit component 202.

[0036] In this embodiment, by setting the positioning component 103, the mounting seat component 101 can be installed on the roof, and by setting the mounting seat component 101, the fire detector body 102 can be installed. By setting the limiting annular groove 201 and the locking component 202, the preliminary locking positioning of the mounting seat component 101 and the fire detector body 102 can be achieved. By setting the fixing component 300, the rapid installation and fixation between the mounting seat component 101 and the fire detector body 102 can be achieved.

[0037] Furthermore, the mounting seat assembly 101 includes a mounting seat body 1011, a snap-in groove 1012 opened on the lower surface of the mounting seat body 1011, and a wire arrangement groove 1013 opened at the top of the snap-in groove 1012. The fire detector body 102 is snap-into the interior of the mounting seat body 1011 through the snap-in groove 1012. By setting the snap-in groove 1012, the fire detector body 102 can be inserted into the interior of the mounting seat body 1011. By setting the wire arrangement groove 1013, the installation of the connecting wire of the fire detector body 102 is facilitated.

[0038] Furthermore, the positioning assembly 103 includes a positioning ring 1031 fixedly sleeved on the mounting base assembly 101, and a positioning bolt 1032 threadedly sleeved on the positioning ring 1031. A positioning groove 1033 is provided on the positioning ring 1031 relative to the positioning bolt 1032. By inserting the positioning bolt 1032 into the positioning groove 1033, the positioning ring 1031 can be installed on the roof, thereby completing the fixation of the mounting base body 1011.

[0039] Furthermore, the locking assembly 202 includes an arc-shaped plate 2021 installed at the top end of the limiting annular groove 201, a convex groove 2022 opened on one side of the arc-shaped plate 2021, and a convex plate 2023 movably locked in the convex groove 2022. The limiting annular groove 201 is opened at the top end of the clamping groove 1012, and the lower surface of the convex plate 2023 is connected to the upper surface of the fire detector body 102. When installing the fire detector body 102, first insert the fire detector body 102 into the clamping groove 1012, and make the convex plate 2023 fall into the inside of the limiting annular groove 201, and then rotate the fire detector body 102 so that the convex plate 2023 is inserted into the inside of the convex groove 2022 opened on one side of the arc-shaped plate 2021, thereby completing the initial fixation of the fire detector body 102 to prevent it from detaching from the inside of the mounting seat body 1011.

[0040] Among them, the number of the locking components 202 is four, and the four locking components 202 are all equidistantly arranged on the same circle with the axis of the limiting annular groove 201 as the center. In this way, the stability between the fire detector body 102 and the mounting seat body 1011 can be increased.

[0041] Furthermore, the cavity rod 301 is embedded and installed inside the mounting seat body 1011, and the built-in rod 302 and the spring 303 are both movably connected to the inside of the cavity rod 301. The spring 303 is arranged on the outside of the built-in rod 302, and a linkage plate 304 is provided inside the cavity rod 301. The linkage plate 304 is fixedly connected to the built-in rod 302. The two ends of the spring 303 are respectively connected to the internal top of the cavity rod 301 and one side of the linkage plate 304. The fixing groove 305 is opened on the arc plate 2021, and the bottom of the fixing groove 305 passes through the inside of the convex plate 2023. The size value of the fixing groove 305 is adapted to the built-in rod 302.

[0042] After the fire detector body 102 is inserted into the snap-fit groove 1012 and before the fire detector body 102 is rotated, the built-in rod 302 is first pulled outward, and the built-in rod 302 drives the linkage plate 304 to move synchronously, and the spring 303 is compressed until the built-in rod 302 is pulled outward to the maximum position, and then the fire detector body 102 is rotated so that the convex plate 2023 is inserted into the inner bottom end position of the convex groove 2022 opened on one side of the arc plate 2021. At this time, the fixing groove 305 on one of the snap-fit components 202 corresponds to the position of the built-in rod 302. At this time, the built-in rod 302 is released, and under the action of the reset force of the spring 303, the built-in rod 302 can be inserted into the inside of the fixing groove 305, thereby realizing rapid fixation between the fire detector body 102 and the mounting seat body 1011, and the fixing method is relatively simple.

[0043] If it is necessary to disassemble it, first pull the built-in rod 302 outward to the maximum position, and then rotate the fire detector body 102 in the opposite direction to complete the disassembly of the fire detector body 102. The disassembly method is relatively simple.

[0044] Example 2

[0045] The second embodiment is an improvement based on the first embodiment. The difference from the first embodiment is that Figure 2 、 Figure 3 and Figure 6 , also includes a reinforcement component 400, the reinforcement component 400 includes a reinforcement bolt 401 threadedly connected to the mounting seat component 101 and the clamping component 202; a reinforcement thread groove 402 is opened on the mounting seat body 1011, the arc plate 2021 and the convex plate 2023 at a position relative to the reinforcement bolt 401.

[0046] In this embodiment, by setting up a reinforcement component 400, the mounting base body 1011 and the fire detector body 102 can be reinforced and fixed. Specifically, after being fixed by the fixing component 300, the reinforcement bolt 401 is inserted into the corresponding reinforcement thread groove 402.

[0047] Furthermore, a heat dissipation groove 500 is provided at the inner bottom of the limiting annular groove 201 , and a dustproof net 600 is provided inside the heat dissipation groove 500 . By providing the heat dissipation groove 500 and the dustproof net 600 , heat dissipation and dust prevention can be achieved.

[0048] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
