An ion type smoke sensor is adopted inside the smoke detector. The ion type smoke sensor is a sensor with advanced technology and stable and reliable operation, and is widely used in various fire alarm systems, and its performance is far superior to that of a gas sensitive resistor type fire alarm.

[0003] The smoke sensing device is widely used, and among them, it is most commonly used in buildings. The existing installation method is generally to drill holes in the wall surface, and then directly fix the smoke sensing device on the wall surface by using expansion screws.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figures 1-4 shown, an installation structure of a smoke sensing device includes a mounting base 14, an insertion rod 5, a backing plate 11 and a smoke sensor 8. A connecting rod 1 is arranged at the center position of the upper surface of the mounting base 14, and a chassis 15 is connected through the connecting rod 1. The chassis 15 and the connecting rod 1 are buried in the wall surface. A threaded hole 2 is arranged at the center position of the bottom of the mounting base 14, and a plurality of card slots 13 are arranged in a circular matrix distribution with the axis of the mounting base 14 as the center. A plurality of buckles 3 corresponding to the card slots 13 are arranged on the upper surface of the backing plate 11, and a through hole 9 is opened at the center of the backing plate 11. The backing plate 11 is inserted into the card slot 13 through a card plate and is rotationally connected with the mounting base 14 by rotating counterclockwise. A threaded column 7 matching the threaded hole 2 is arranged at the center position of the upper surface of the smoke sensor 8, and the smoke sensor 8 is screwed with the threaded hole 2 by passing the threaded column 7 through the through hole 9 and rotating clockwise. The insertion rod 5 is U-shaped. First jacks 10 and second jacks 12 are respectively opened on the side walls of the backing plate 11 and the smoke sensor 8, and the insertion rod 5 is respectively inserted into the first jack 10 and the second jack 12; a plurality of groups of the insertion rod 5, the first jack 10 and the second jack 12 are respectively arranged and are evenly distributed on the side walls of the backing plate 11 and the smoke sensor 8; an elastic rubber sleeve 6 is sleeved on the insertion rod 5, and the rubber sleeve 6 is press-fitted into the first jack 10 and the second jack 12; a hole 4 is opened at the center position of the insertion rod 5; the backing plate 11 is made of a material with a waterproof effect.

[0021] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the attached Figures 1-4 As can be seen, in the present utility model, the mounting base 14 is buried in the wall through the connecting rod 1 and the chassis 15. This is set during the wall construction, avoiding the positions of pipelines and cables. The mounting base 14 only needs to protrude from the wall surface. Here, the wall surface also includes the roof of the building. Since a plurality of card slots 13 are arranged in a circular matrix at the bottom of the mounting base 14 with its axis as the center, and a plurality of buckles 3 corresponding to the card slots 13 are arranged on the upper surface of the backing plate 11, the backing plate 11 can be inserted into the slots through the buckles 3 and then rotated counterclockwise to be clamped with the mounting base 14, ensuring its stability in the axial direction, and the backing plate 11 can no longer be rotated counterclockwise. Since a threaded hole 2 is provided at the center position of the bottom of the mounting base 14, and a threaded post 7 is provided at the center position of the upper surface of the smoke sensor 8, the threaded post 7 passes through the through hole 9 of the backing plate 11 and is screwed with the threaded hole 2 until it is tightened. It should be noted here that the design of the thread direction should ensure that the threaded post 7 is rotated clockwise to be tightened, stabilizing the axial direction of the smoke sensor 8, and the smoke sensor 8 can no longer be rotated clockwise. Finally, the U-shaped insertion rod 5 is respectively inserted into the first insertion hole 10 and the second insertion hole 12 on the side walls of the backing plate 11 and the smoke sensor 8. The insertion design of the insertion rod 5 makes the backing plate 11 and the smoke sensor 8 integrated. The backing plate 11 can no longer be rotated counterclockwise, and the smoke sensor 8 can no longer be rotated clockwise, thus ensuring the stability of the installation of the smoke sensor 8. Compared with the prior art, the mounting base 14 is pre-embedded in advance. For the positions of pipelines and cables, the backing plate 11 and the smoke sensor 8 are simply rotated, and finally fixed by inserting the insertion rod 5. The fixing method is simple and convenient. When disassembling, only need to pull out the insertion rod 5 and rotate the smoke sensor 8 and the backing plate 11 in the reverse direction to remove them, which is convenient for disassembly and installation.

[0023] Among them, multiple groups of insertion rods 5, first insertion holes 10 and second insertion holes 12 are respectively provided, and are evenly distributed on the side walls of the backing plate 11 and the smoke sensor 8, further ensuring the stability of the installation of the smoke sensor 8 and the backing plate 11.

[0024] Among them, an elastic rubber sleeve 6 is sleeved on the insertion rod 5, and the rubber sleeve 6 is inserted into the first insertion hole 10 and the second insertion hole 12 by interference fit. By inserting the rubber sleeve 6 into the insertion holes and interference fit, the installation of the insertion rod 5 is stable.

[0025] Among them, a hole 4 is provided at the center position of the insertion rod 5, which is convenient for personnel to use tools to pull out the insertion rod 5.

[0026] Among them, the backing plate 11 is made of a material with waterproof effect, such as rubber, to avoid accidental water leakage on the wall surface from penetrating into the inside of the smoke sensor 8 and causing damage.

[0027] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
