[0002] Smoke sensors, also known as smoke alarms or smoke sensors, are mainly used to detect smoke concentrations and sound an alarm when the preset threshold is reached. They are an important part of fire warning systems.

[0003] Smoke sensors usually use photoelectric smoke sensing technology or ionization smoke sensing technology to detect smoke. Photoelectric smoke sensing technology triggers the alarm by detecting the scattering or blocking of light by smoke; ionization smoke sensing technology triggers the alarm by detecting the effect of tiny particles in the smoke on the current in the ionization chamber;

[0004] The installation part of the smoke sensor generally consists of a mounting base and a sensor body. The mounting base is directly fixed to the wall by screws, and then the sensor is connected to the mounting base by bolts or snap-fitting;

[0005] Although the method of connecting the sensor to the mounting base through bolts is reliable and stable, the operation is not convenient enough, which is not conducive to later maintenance. In addition, the bolts are easy to fall off after being separated from the threads during installation and removal, which affects the installation and removal work. The general clamping is through ordinary clamping blocks and slot structures, which are pressed to engage and pulled out by force. Although this method has the advantage of convenient operation, it has poor stability and the structure is too simple and easy to operate, which affects safety.

[0006] In order to solve the above problems, the present application proposes a quick installation structure of a smoke sensor. Utility Model Content

[0030] See also Figure 1-5As shown, the utility model is a quick installation structure of a smoke sensor, including a sensor body 1 and a mounting seat 3, a rotating movable sleeve 2 is provided on the outside of the sensor body 1, an elastic card block 11 is provided on the sensor body 1, a card slot 31 engaged with the elastic card block 11 is opened in the mounting seat 3, the elastic card block 11 and the card slot 31 are both located on the inner side of the movable sleeve 2, an elastic pressure plate 21 is provided on the movable sleeve 2, a pressing pin 22 is fixed on the inner side of the pressure plate 21, the elastic card block 11 and the card slot 31 are separated by the push of the pressing pin 22, and the pressing pin 22 can rotate along the mounting seat 3.

[0031] Among them, the mounting seat 3 is provided with a straight groove 32 located directly below the card slot 31, and the bottom of the straight groove 32 is opened. The mounting seat 3 is provided with a horizontal groove 33 with one end communicating with the top of the side of the straight groove 32. The pressing pin 22 slides in the straight groove 32 and the horizontal groove 33. In this embodiment, the straight groove 32 can allow the pressing pin 22 to enter during the engagement process of the elastic card block 11 and the card slot 31, so that the pressing pin 22 can enter the horizontal groove 33, thereby providing a channel for the cooperation between the pressing pin 22 and the mounting seat 3.

[0032] Among them, an avoidance groove 34 is opened at the upper part of the end of the horizontal groove 33, and a stop block 35 is formed at the lower part of the end of the horizontal groove 33. The pressing pin 22 is clamped at the end of the horizontal groove 33 through the stop block 35. In this embodiment, the cooperation between the avoidance groove 34 and the stop block 35 can limit the pressing pin 22 at the end of the horizontal groove 33, and also limit the rotation of the movable sleeve 2, which plays the role of elastic locking and preventing misoperation.

[0033] Among them, when the pressing pin 22 is located inside the straight groove 32, it is opposite to the outside of the elastic block 11, and the front end of the pressing pin 22 slides on the outside of the sensor body 1. In this embodiment, the straight groove 32 can be used for the separation and docking between the pressing pin 22 and the mounting seat 3, and can also accurately determine the matching position of the pressing pin 22 and the elastic block 11 to ensure that after pressing the pressure plate 21, the pressing pin 22 can squeeze the elastic block 11 to separate from the slot 31. At the same time, as shown in the figure, a movable space is provided at the top of the straight groove 32 for the pressing pin 22 to be pressed.

[0034] Among them, an annular sleeve is formed at the lower end of the mounting seat 3, and an annular groove for plugging the annular sleeve is arranged between the sensor body 1 and the movable sleeve 2. The annular groove and the annular sleeve structure in this embodiment not only provide a connection platform for the sensor body 1, the movable sleeve 2, and the mounting seat 3, but also can improve the overall structural strength after docking.

[0035] Among them, an annular seat 23 is formed at the inner bottom of the movable sleeve 2, and a rotating ring 12 is formed on the outside of the sensor body 1. The movable sleeve 2 is rotatably connected to the outside of the sensor body 1 through the rotating ring 12 and the annular seat 23. The rotating connection structure in this embodiment ensures the stability and fit of the movable sleeve 2 on the sensor body 1.

[0036] Among them, the upper ends of the sensor body 1 and the movable sleeve 2 are flush, the outer side of the mounting seat 3 is provided with a plane that fits and contacts with the top of the sensor body 1 and the movable sleeve 2, and the outer sides of the joints between the movable sleeve 2 and the mounting seat 3 are flush. In this embodiment, the connection between the sensor body 1, the movable sleeve 2, and the mounting seat 3 not only ensures the connection reliability, but also ensures the aesthetics.

[0037] It can be understood that, firstly, the elastic block 11 and the slot 31 are arranged to enable quick engagement while ensuring engagement stability; secondly, a rotatable movable sleeve 2 is arranged, and the pressure pin 22 inside the movable sleeve 2 is misaligned with the elastic block 11 to avoid misoperation of the pressure plate 21, thereby improving the stability of the sensor after installation.

[0038] A specific application of this embodiment is as follows: the mounting seat 3 is provided with mounting holes for expansion screws and screws, and the mounting seat 3 is directly fixed to the wall. When docking, the pressing pin 22 on the inner side of the movable sleeve 2 is rotated to a position facing the elastic block 11, and the elastic block 11 is aligned with the card slot 31, and the sensor body 1 and the movable sleeve 2 are pushed upward. The mounting seat 3 is inserted between the sensor body 1 and the movable sleeve 2. At this time, the elastic block 11 is squeezed outward until it is matched with the card slot 31 and engaged with it. During the engagement process, the elastic block 11 slides upward from the inside of the straight groove 32 to the horizontal groove 33 At this time, hold the movable sleeve 2 and rotate it, the pressing pin 22 slides inside the horizontal groove 33, and after the pressing pin 22 contacts the stopper 35, continue to rotate the movable sleeve 2 with force until the pressing pin 22 passes through the avoidance groove 34 and the stopper 35 and is stuck at the bottom of the horizontal groove 33. At this time, the sensor body 1, the movable sleeve 2, and the mounting seat 3 are installed. In this state, since the front end of the pressing pin 22 is against the sensor body 1, even if the pressing plate 21 is pressed, the elastic block 11 and the slot 31 will not be disengaged, and the damping generated by the pressing pin 22 and the stopper 35 can prevent misoperation.

[0039] When disassembling: hold the movable sleeve 2 and rotate it in the opposite direction. Since there will be a certain resistance between the pressing pin 22 and the block 35, a certain amount of force is required. After the pressing pin 22 passes through the block 35, it slides to the other end inside the horizontal groove 33. At this time, the front end of the pressing pin 22 is facing the elastic block 11. After pressing the pressure plate 21, the elastic block 11 is squeezed inwardly under the action of the pressing pin 22. After being squeezed, the elastic block 11 disengages from the card slot 31, and then the sensor body 1 and the movable sleeve 2 are taken out downward, and the pressing pin 22 moves downward along the straight groove 32 and disengages.
