[0002] The occurrence of fire is often accompanied by casualties and property losses. In order to prevent fire, people install different types of fire alarms in various places. The most widely used one is the smoke alarm. The smoke alarm achieves fire prevention by monitoring the concentration of smoke. The internal ion smoke sensor is a technologically advanced, stable and reliable sensor. It is widely used in various fire alarm systems. Its performance is far superior to that of gas sensitive resistor fire alarms. Usually the smoke alarm is installed on the top of the room with screws.

[0003] In order to facilitate the installation of the fire alarm, the prior art has made many improvements to the installation structure of the fire alarm. For example, the patent with patent publication number CN219588662U discloses a fire alarm with an installation structure, which includes a fixed block, a rotating block, and a smoke alarm; the rotating block is installed under the fixed block and connected to the fixed block, and a sliding groove is provided on the rotating block, and a connecting arm is slidably installed in the sliding groove; a fixed component is used to adjust the connecting arm to slide in the sliding groove, thereby driving the connecting arm to contract, so as to fix and clamp the smoke alarm; the device can fix and clamp smoke alarms of different sizes through the extension and contraction of the connecting arm, and at the same time, the smoke alarm can be easily disassembled, replaced and repaired through the connecting arm and torsion spring and other mechanisms, which facilitates the operation of workers, and the height of the smoke alarm can be easily adjusted according to the environment through the winding wheel and the pull rope structure, thereby improving the alarm effect of the smoke alarm and improving the applicability of the device.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] The above-mentioned comparative document can fix and clamp smoke alarms of different sizes by extending and retracting the connecting arm, and the fixing force comes from the elastic part and the torsion spring. The fixing effect is poor for smoke alarms with a large difference in volume. In the existing situation, the smoke alarm is basically installed on the indoor ceiling. If the indoor ceiling vibrates strongly, it will cause the elastic part and the torsion spring to deform, which may cause the smoke alarm to fall off. In addition, the structure in the above-mentioned comparative document is complicated, which increases the cost of installing the smoke alarm. Therefore, the art urgently needs to improve the fire alarm with a mounting structure to solve the defects of the prior art. Utility Model Content

[0029] Specific implementation method in this embodiment: the alarm body mentioned above is a smoke alarm in the prior art, wherein an ion smoke sensor is installed in the mounting cover 1, and the substrate 3 mentioned above is an existing indoor ceiling. When the alarm body needs to be installed, first determine the location where the alarm body needs to be installed, open a mounting hole 4 that is adapted to the mounting seat 2 on the substrate 3, first install the mounting seat 2, rotate the clamping plate 5 to be parallel to the side plate 7 during installation, and pass the side plate 7 through the mounting hole 4 on the substrate 3, the upper side of the mounting seat 2 is attached to the lower surface of the substrate 3, and the mounting bolts 6 are installed. The end passes through the mounting hole 4, one end of the mounting bolt 6 will push the clamping plate 5 up, and the clamping plate 5 will rotate. When the sliding column 8 moves to the top in the sliding groove 9, the clamping plate 5 will not move. At this time, due to the pushing of the mounting bolt 6, the clamping plate 5 will be horizontal. The end of the mounting bolt 6 is threadedly connected to the threaded hole 10. When the mounting bolt 6 is rotated, the clamping plate 5 will move down, and the clamping plate 5 moves down to be in contact with the upper surface of the substrate 3. After tightening the mounting bolt 6, the installation of the mounting seat 2 is completed. The mounting cover 1 is installed on the lower part of the mounting seat 2 by means of a threaded connection to complete the installation of the early warning device body.

[0030] A chemical power source is provided in the body of the wireless early warning device and is fixedly mounted in the mounting cover 1. In the prior art, the chemical power source needs to be replaced regularly. When the chemical power source is replaced, the mounting cover 1 is disassembled by rotation and the chemical power source inside is replaced.

[0031] If it is necessary to replace the installed early warning device body, first remove the mounting cover 1, and then rotate the mounting bolt 6 in the opposite direction. At this time, the clamping plate 5 is away from the base plate 3 until one end of the mounting bolt 6 is disengaged from the threaded hole 10. Remove the mounting bolt 6 and use a thin object to guide the clamping plate 5 and the side plate 7 to be parallel. Then, the mounting base 2 can be disassembled and the mounting base 2 can be reused. The overall mounting structure is simple and can be reused, which improves the strength of the early warning device body after installation and reduces the cost of installing the early warning device body.

[0032] It is worth noting that the above installation method is for the indoor substrate 3 with a suspended ceiling. When the alarm body needs to be installed in the position of the substrate 3 without a suspended ceiling, it can be installed directly by fasteners such as expansion bolts penetrating the installation hole 4.

[0033] Embodiment 2

[0034] See also Figure 4 This embodiment includes the above embodiment, wherein it further includes: a clamping ring 11 is fixedly connected between the lower ends of the two side plates 7, and the diameter of the clamping ring 11 is larger than the inner diameter of the mounting hole 4.

[0035] Specific implementation method in this embodiment: when the mounting base 2 needs to be installed, the side panel 7 is inserted into the mounting hole 4 on the mounting base 2 and the base plate 3 through the clamping ring 11, and the upper side surface of the clamping ring 11 is against the inner wall of the mounting base 2. When installing different types of early warning device bodies, it is only necessary to open the mounting hole 4 in the mounting base 2. Even if the early warning device body is damaged, the side panel 7 and the clamping ring 11 can still be used, which further reduces the installation cost of the early warning device body.

[0036] Embodiment 3

[0037] See also Figure 1-Figure 5 This embodiment includes all the above embodiments, which further includes: an open groove 12 is opened in the opposite side walls of each sliding groove 9, and elastic sheets 13 are fixedly installed on the inner walls of several open grooves 12. Several elastic sheets 13 are used to limit the sliding column 8. The two ends of the clamping plate 5 are asymmetrically arranged with the sliding column 8 as the center. Guide fillets 14 are opened at both ends of the clamping plate 5. A semicircular block 15 is provided at the end of the mounting bolt 6 away from the screw head, and a plurality of anti-slip grooves 16 are opened on the opposite sides of the clamping plate 5.

[0038] Specific implementation method of this embodiment: during installation, first move the sliding column 8 to the upper end of the sliding groove 9. Since the sliding column 8 is limited by a plurality of elastic sheets 13, the sliding column 8 will not move downward. The mounting bolt 6 passes through the mounting hole 4. Through the cooperation of the guide fillet 14 and the semicircular block 15, it is easier to push and rotate the clamping plate 5. After one end of the mounting bolt 6 is threadedly connected with the threaded hole 10, rotating the mounting bolt 6 will drive the clamping plate 5 to move downward. At this time, the sliding column 8 will squeeze the elastic sheet 13 in the open groove 12 to produce deformation, and the pressure plate 5 will be pressed. The clamping plate 5 continues to move downward. When the mounting seat 2 is disassembled, the mounting bolt 6 is rotated in the opposite direction to push the clamping plate 5 upward until the sliding column 8 returns to the upper end of the sliding groove 9 again. At this time, the mounting bolt 6 is disengaged from the threaded hole 10. The mounting bolt 6 is removed. Since the clamping plate 5 is asymmetrical on both sides of the sliding column 8, the clamping plate 5 will automatically rotate. The clamping plate 5 is parallel to the side plate 7, and the side plate 7 can be taken out of the mounting hole 4, which is convenient for the installer to install and disassemble. The anti-slip groove 16 increases the clamping force of the clamping plate 5 on the substrate 3.

[0039] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
