Description

Technical Field

[0001] The utility model relates to the technical field of smoke detectors, and in particular to a smoke detector that is convenient to install and fix. Background Art

[0002] Smoke detectors are products that sense smoke concentration, determine whether there is a fire hazard, and then issue an alarm to notify of the danger. They are widely used in indoor places such as offices, hotels, and buildings, and are a good product for fire early warning. There are many types of smoke detectors in the existing technology, but they generally include: a main body and a base. The main body is installed on the base to complete the assembly and has a warning light;

[0003] For example, a smoke detector disclosed in the patent document with the publication number "CN213458356U" includes: a detector body with a circuit board installed inside and an indicator light provided on the detector body; a base for mounting the detector body; a slide rail provided on the base; a slide groove that cooperates with the slide rail structure provided on the back of the detector body; and the detector body is horizontally slidably assembled on the base. The utility model is provided with a three-color indicator light around the test button, and different colors of the indicator lights light up to provide different states or functions; at the same time, the indicator light is assembled in a plug-in manner, which is simple and convenient to install; the detector body and the base are slidably assembled, and the hook is inserted into the slot. The limiting protrusion and the limiting slot interact with each other, so that the detector body and the base are limited in both the horizontal and vertical directions, and the assembly is more stable.

[0004] In the prior art, the warning light of the smoke detector generally needs to be oriented toward a preset direction during installation, and the base and the detector body are usually fixed together by snapping together. Since the detector body cannot change its direction again after snapping together, it is necessary to pre-design the installation direction of the base when installing the base, and calculate the punching position of the installation base in advance. The installation preparation work is relatively cumbersome. Once the punching position deviates, it can only be re-drilled and reinstalled. The installation and debugging process is relatively inconvenient. Therefore, a smoke detector that is easy to install and fix is needed. Utility Model Content

[0014] When the limiting slip ring moves up to the limiting position and is inserted into the limiting hole, the movable limiting plate pops out under the elastic action of the limiting spring and makes the top wall of the movable limiting plate abut against the lower end surface of the limiting slip ring.

[0015] Preferably, a paddle is integrally formed at the lower end of the movable limiting plate, and the paddle extends downward and protrudes outside the mounting hole or the lower end of the limiting slip ring.

[0018] In summary, the technical effects and advantages of the utility model are:

[0019] 1. In the present invention, through the arrangement of the connecting piece and the connecting ring, after the detector body is connected to the connecting ring through the connecting clamp plate and the connecting block, since the connecting ring is rotatably connected to the mounting base, the installed detector body can still be rotated, and the rotation angle is consistent with the rotation angle of the connecting ring, both are 360°, so it is convenient to adjust the direction of the warning light on the detector body after the detector body is installed. Therefore, it is possible to avoid the need to preset the installation orientation of the mounting base in advance and the need to calculate the drilling position for installing the mounting base in advance, thereby avoiding tedious preparation work and the possibility of needing to redo the drilling installation when the drilling position deviates. The simplified installation operation is simple and quick, and the construction is easier.

[0020] 2. In the present invention, through the setting of the limit slip ring and the limit house, when the adjustment of the detector body is completed, the installer only needs to push the limit slip ring to make the limit slip ring slide upward, and finally make the limit house inserted in the limit hole, so as to limit the limit slip ring circumferentially and prevent the limit slip ring from rotating. At this time, since the limit slip ring and the detector body are in sliding connection, the detector body is also limited and cannot rotate, which is conducive to limiting the detector body after the adjustment is completed, so that it is fixed in the preset installation orientation, avoiding the detector body from being rotated by external force after installation, resulting in the need for readjustment.

[0021] 3. In the present invention, through the arrangement of the fixed plate, the movable limit plate and the limit spring, when the limit slip ring moves up to the limit housing and is inserted into the limit hole, the movable limit plate pops out under the elastic action of the limit spring and makes the top wall of the movable limit plate abut against the lower end face of the limit slip ring, thereby preventing the limit slip ring from sliding downward due to external force or its own gravity, thereby preventing the detector body from losing its limit due to the separation of the limit slip ring and the limit housing, which can more effectively ensure the installation stability of the detector body and improve the reliability of the smoke detector after installation.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example: Reference Figure 1-4 The smoke detector shown here is convenient for installation and fixation, and includes a mounting base 1 and a detector body 3. The mounting base 1 is provided with a mounting hole 11 for inserting a bolt. A connecting ring 2 is rotatably connected to the threading hole in the mounting base 1 via a connecting member. The connecting member is a connecting bearing 4. The inner ring of the connecting bearing 4 is fixed to the outer wall of the connecting ring 2, and the outer ring of the connecting bearing 4 is fixed to the inner top wall of the mounting base 1, thereby realizing a rotatable connection between the connecting ring 2 and the mounting base 1. The connecting ring 2 rotates 360 degrees.

[0030] At least two connection blocks 5 are fixed around the connecting ring 2, and the connection blocks 5 are located at the lower end of the connecting ring 2;

[0031] At least two connecting clamps 7 are fixed to the upper end of the detector body 3 . The connecting clamps 7 are L-shaped plates and are engaged with the connecting block 5 .

[0032] Based on the above structure, when the detector body 3 is connected to the connecting ring 2 through the connecting clamp 7 and the connecting block 5, since the connecting ring 2 is rotatably connected to the mounting base 1, the detector body 3 can still be rotated after installation, and the rotation angle is consistent with the rotation angle of the connecting ring 2, both being 360°, so that it is convenient to adjust the direction of the warning light on the detector body 3 after the detector body 3 is installed. Therefore, it is possible to avoid the need to preset the installation orientation of the mounting base in advance and the need to calculate the drilling position of the mounting base in advance, thereby avoiding tedious preparation work and the possibility of re-drilling and installation when the drilling position deviates. The simplified installation operation is simple and quick, and the construction is easier.

[0033] Furthermore, a limiting mechanism is installed on the outer side of the detector body 3 and the mounting base 1. The limiting mechanism is used to limit the detector body 3 from rotating after the orientation of the detector body 3 is adjusted.

[0034] The limiting mechanism includes a limiting slip ring 6 and a limiting housing 12. The limiting slip ring 6 is slidably sleeved on the outside of the detector body 3. Specifically, a guide slide 31 is fixed to the circumference of the detector body 3. A sliding groove 62 is provided on the inner side of the limiting slip ring 6 and is slidably connected to the guide slide 31. A plurality of limiting housings 12 are provided and distributed in an array along the circumference of the inner top wall of the mounting base 1.

[0035] The upper end of the limiting slip ring 6 is provided with a plurality of limiting holes 61 which are plugged into the limiting housing 12;

[0036] An anti-drop assembly 8 for limiting the lower end of the limiting slip ring 6 is installed in the middle of the detector body 3 .

[0037] Through the setting of the limiting slip ring 6 and the limiting house 12, when the adjustment of the detector body 3 is completed, the installer only needs to push the limiting slip ring 6 to make the limiting slip ring 6 slide upward, and finally make the limiting house 12 inserted into the limiting hole 61, so as to limit the limiting slip ring 6 circumferentially, so that the limiting slip ring 6 cannot rotate. At this time, since the limiting slip ring 6 and the detector body 3 are in sliding connection, the detector body 3 is also limited and cannot rotate, which is conducive to limiting the detector body 3 after the adjustment is completed, so that it is fixed in the preset installation orientation, avoiding the detector body 3 from being rotated by external force after installation, resulting in the need for readjustment.

[0038] Furthermore, the anti-slip assembly 8 includes a fixed plate 81, a movable limiting plate 82 and a limiting spring 83. The upper end of the fixed plate 81 is fixed to the top surface of the middle part of the detector body 3, the movable limiting plate 82 is slidably connected to the top surface of the middle part of the detector body 3, and the movable limiting plate 82 is elastically connected to the fixed plate 81 through the limiting spring 83.

[0039] By setting the fixed plate 81, the movable limiting plate 82 and the limiting spring 83, when the limiting slip ring 6 moves up to the limiting house 12 and is inserted into the limiting hole 61, the movable limiting plate 82 pops out under the elastic action of the limiting spring 83 and makes the top wall of the movable limiting plate 82 abut against the lower end face of the limiting slip ring 6, thereby preventing the limiting slip ring 6 from sliding downward due to external force or its own gravity, thereby preventing the detector body 3 from losing its limit due to the separation of the limiting slip ring 6 from the limiting house 12, which can more effectively ensure the installation stability of the detector body 3 and improve the reliability of the smoke detector after the installation is completed.

[0040] Furthermore, a paddle 84 is integrally formed at the lower end of the movable limit plate 82, and the paddle 84 extends downward and protrudes outside the mounting hole 11 or the lower end of the limit slip ring 6, so that the movable limit plate 82 can be pulled when disassembly is needed later, so that the movable limit plate 82 is separated from the lower end of the limit slip ring 6, thereby releasing the limit on the limit slip ring 6, and further the limit slip ring 6 can be disassembled, so that the detector body 3 can be disassembled, which is convenient for subsequent disassembly and maintenance operations.

[0041] The working principle of the present invention: During daily use, first, a hole is drilled at a predetermined installation position indoors. The hole position only needs to meet the requirements of installing the mounting base 1. There is no need to calculate the installation orientation of the mounting base 1. Then, the mounting base 1 is installed on the indoor ceiling by bolts, and further connected by connecting the clamping plate 7 and the connecting block 5, so that the detector body 3 is clamped on the connecting ring 2. At this time, since the connecting ring 2 is rotatably connected to the mounting base 1, the installed detector body 3 can still be rotated, and the rotation angle is consistent with the rotation angle of the connecting ring 2, both of which are 360°, so that it is convenient to adjust the direction of the warning light on the detector body 3 after installing the detector body 3. Therefore, it can avoid the need to preset the installation orientation of the mounting base in advance and the need to calculate the installation orientation of the mounting base in advance. The hole position is simplified, thereby avoiding tedious preparation work and the possibility of redrilling and installing when the drilling position deviates. The simplified installation operation is simple and fast, and the construction is easier. When the detector body 3 is adjusted, the installer only needs to push the limit slip ring 6 to make the limit slip ring 6 slide upward, and finally make the limit house 12 inserted in the limit hole 61, so that the limit slip ring 6 can be circumferentially limited, so that the limit slip ring 6 cannot rotate. At this time, since the limit slip ring 6 and the detector body 3 are in a sliding connection, the detector body 3 is also limited and cannot rotate, which is conducive to limiting the detector body 3 after the adjustment is completed, so that the detector body 3 is fixed in the preset installation orientation, avoiding the detector body 3 from being rotated by external force after installation, resulting in the need for readjustment.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
