Description
Technical Field
[0001] The utility model relates to the technical field of smoke detectors, in particular to a fixing structure of a smoke detector. Background Art
[0002] A smoke detector is an early warning device that detects smoke concentration in the air. It is commonly used in residential, office buildings, factories and other places to prevent fires. Smoke detectors monitor smoke particles through sensors, and once a certain concentration of smoke is detected, an audible and visual alarm will be issued to alert people to pay attention and take action.
[0003] When using existing smoke detectors, most of them are installed on the ceiling by screws. When fixing the smoke detector, it is necessary to use tools to repeatedly rotate it, which is troublesome to fix the smoke detector. Since most smoke detectors are powered by internal batteries, after using them for a period of time, the smoke detector needs to be removed and the battery needs to be replaced. The smoke detector fixed with screws is troublesome to disassemble and has low work efficiency. Therefore, we propose a fixing structure for the smoke detector. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Embodiment 1:
[0020] See also Figure 1-3The utility model provides a technical solution: a fixing structure of a smoke detector, comprising a mounting plate 1 and a smoke detector body 2, expansion bolts 3 are threadedly connected to both ends of the mounting plate 1, and two groups of T-slots 9 are opened on the bottom wall of the mounting plate 1, T-slide blocks 10 are slidably connected in the two groups of T-slots 9, and movable plates 4 are installed on the bottom walls of the two groups of T-slots 10, the bottom of the movable plate 4 is rotatably connected to a damping shaft 5 through a bearing, and a baffle 6 is provided at the bottom of the damping shaft 5, U-shaped seats 12 are installed on the outer side walls of the two groups of movable plates 4, and the open ends of the U-shaped seats 12 are directly opposite to the T-slots 9, and a limiting unit is provided between the U-shaped seat 12 and the T-slot 9.
[0021] The smoke detector body 2 is an existing device, and the specific working principle is not described here. Before use, first, a threaded hole compatible with the expansion bolt 3 is opened on the ceiling, and the mounting plate 1 is fixed to the ceiling by the expansion bolt 3. When installing the smoke detector body 2, the spacing between adjacent movable plates 4 is adjusted so that the inner side surfaces of the two sets of movable plates 4 are both attached to the outer walls of the two sides of the smoke detector body 2. Then, by rotating the damping shaft 5, the baffle 6 is brought close to the smoke detector body 2, and the baffle 6 is attached to the lower surface of the smoke detector body 2. The two sets of movable plates 4. The two groups of baffles 6 realize the fixation of the left and right ends and the upper and lower ends of the smoke detector body 2, and the fixing effect of the smoke detector body 2 is good. In the process of adjusting the movable plate 4, the locking block 16 in the limit unit is not connected with the corresponding locking hole 11. After the position of the movable plate 4 is determined, the locking block 16 in the limit unit is connected with the corresponding locking hole 11, that is, the position of the movable plate 4 is fixed to prevent the movable plate 4 from sliding. When disassembling, the rotation of the damping shaft 5 rotates the baffle 6 and keeps the baffle 6 away from the lower surface of the smoke detector 2.
[0022] Among them, preferably, a limiting rod 7 is connected to the lower surface of the mounting plate 1, and a limiting hole 8 adapted to the limiting rod 7 is opened on the top of the smoke detector body 2; through the connection between the limiting rod 7 and the limiting hole 8, the front and back and left and right ends of the smoke detector body 2 are limited after installation.
[0023] Preferably, the limiting unit includes an operating rod 13, which is slidably connected in the U-shaped seat 12, and a locking block 16 is provided at the bottom of the operating rod 13, and the inner wall of the T-shaped slot 9 is provided with multiple groups of locking holes 11 that are compatible with the locking block 16; the U-shaped seat 12 is fixedly connected to the movable plate 4, and the operating rod 13 is fixedly connected to the locking block 16.

The outer wall of the operating rod 13 is sleeved with a compression spring 14, and the compression spring 14 is located between the bottom of the slide plate 15 and the inner wall of the U-shaped seat 12; the slide plate 15 is fixedly connected to the operating rod 13. During the adjustment process of the movable plate 4, the operating rod 13 in the U-shaped seat 12 is pulled down, and the slide plate 15 at this time moves down, the compression spring 14 is compressed, and the locking block 16 is received in the U-shaped seat 12. At this time, the T-shaped slide block 10 can slide smoothly in the T-slot 9. When the position of the movable plate 4 is determined, the locking block 16 is aligned with a corresponding group of locking holes 11, and the operating rod 13 is released. The compressed compression spring 14 automatically returns to its original position, so that the slide plate 15 moves toward one side of the locking hole 11, so that the locking block 16 is connected to the corresponding locking hole 11, that is, the position of the T-shaped slide block 10 is fixed, and the movable plate 4 is prevented from moving.
[0025] Preferably, a pull ring 17 is installed at the top end of the operating rod 13 ; the pull ring 17 facilitates pulling the operating rod 13 .
