Description

Technical Field

[0001] This utility model relates to the field of smoke sensing technology, and specifically to an adjustment mechanism for a smoke sensing device. Background Technology

[0002] Most smoke detectors on the market have little angle adjustment function after installation. If the mounting plate is misaligned, the detector will tilt, affecting its appearance and detection performance.

[0003] Traditional smoke detectors are adjusted primarily through manual mechanical adjustments and preset basic parameters, with the core focus on sensitivity and installation angle. First, the detector base is secured to the preset position on the ceiling / wall with screws. After adjusting it to the target direction, the limiting screws are tightened to ensure the main body is no longer loose.

[0004] However, the aforementioned traditional devices fix the smoke sensor by tightening screws. When adjustments are needed, the screws must be removed before the position can be adjusted, which is inconvenient for position adjustment and reduces adjustment efficiency. Utility Model Content

The mechanism also includes:

[0034] Drive mechanism 2 is used to drive slide plate 15 to adjust the lateral position of smoke sensor 16;

[0037] The drive mechanism 2 includes a primary screw 21. The middle part of the slide plate 15 is provided with a threaded groove. The primary screw 21 is threadedly connected to the middle part of the slide plate 15. The primary screw 21 is rotatably connected to the inner side of the two side plates 13. The left part of the primary screw 21 passes through the side plate 13 and is fixedly connected to a knob 22.

[0038] In this embodiment, as Figure 1 and Figure 2 As shown, manually turning the knob 22 drives the first-stage screw 21 to rotate. The first-stage screw 21 is threadedly connected to the slide plate 15, causing the slide plate 15 to slide on the outer wall of the slide rod 14, thereby adjusting the position of the smoke sensor 16 horizontally. The position adjustment mechanism 3 is used to adjust the horizontal longitudinal position of the smoke sensor 16, and the angle adjustment mechanism 4 is used to adjust the angle of the smoke sensor 16.

[0039] Example 2

[0040] The difference from Embodiment 1 is that this embodiment discloses a position adjustment mechanism:

The nut 48 is threadedly connected to the outer wall of the bolt 47.

[0048] In this embodiment, as Figure 4 and Figure 5 As shown, the rotating plate 45 rotates parallel to the bottom plane of the second fixed plate 46, which drives the rotating plate 46 to rotate. The fixed base 44 rotates inside the rotating plate 43, which drives the smoke sensor 16 to rotate. The rotating plate 42 rotates parallel to the bottom plane of the first fixed plate 41, which drives the rotating plate 43 to rotate inside the first fixed plate 41, thereby adjusting the angle of the smoke sensor 16. After adjustment, the bolt 47 and nut 48 apply pressure to the plane to fix the angle.

[0049] The working principle of this utility model is as follows:

[0050] Manually turning knob 22 drives the primary screw 21 to rotate. The primary screw 21 is threadedly connected to the slide plate 15, causing the slide plate 15 to slide on the outer wall of the slide rod 14, thereby adjusting the position of the smoke sensor 16 horizontally. Manually turning knob 36 drives the secondary screw 35 to rotate. The secondary screw 35 is threadedly connected to the slide plate 34, causing the slide plate 34 to slide on the outer wall of the guide rod 33, thereby adjusting the position of the smoke sensor 16 vertically. Facing the fixed plate 46, rotating parallel to the bottom plane of the fixed plate 46, drives the rotating plate 45 to rotate. The fixed base 44 rotates inside the rotating plate 43, driving the smoke sensor 16 to rotate. Facing the fixed plate 41, rotating parallel to the bottom plane of the fixed plate 41, drives the rotating plate 42 and the rotating plate 43 to rotate inside the fixed plate 41, thereby adjusting the angle of the smoke sensor 16. After adjustment, the bolt 47 and nut 48 apply pressure to the plane to fix the angle.
