The carrying part is mounted on the inner side. The force guiding part is used to provide power guidance for the matching mechanism.

[0029] The mounting parts include a servo motor 3, a mounting plate 4, a docking joint 5 and a horizontal moving frame 6. The servo motor 3 is fixed on one side inside the mounting seat 1, the mounting plate 4 is fixed on the output end of the servo motor 3, the docking joint 5 is fixed on one end of the mounting plate 4, and the outer side of the docking joint 5 is slidably connected to the horizontal moving frame 6. When the servo motor 3 is started, the output end of the servo motor 3 drives the mounting plate 4 and the docking joint 5 to rotate, so that the docking joint 5 pushes the horizontal moving frame 6 to move by cooperating with the inner side of the inner groove 7.

[0030] The inner side of the horizontal movable frame 6 is provided with a matching inner groove 7 corresponding to the position of the docking head 5. The matching inner groove 7 is slidably connected to the horizontal movable frame 6. When the mounting plate 4 rotates, the docking head 5 can be driven to push the horizontal movable frame 6 to move through the matching inner groove 7.

[0031] The force guiding member comprises an auxiliary vertical rod 8, a carrying top rod 9, a force guiding transmission groove 10, a force guiding bottom rod 11, a movable connecting rod 12 and an integrated rod seat 13. An auxiliary vertical rod 8 is fixed to one side of the horizontal moving frame 6, and a carrying top rod 9 is assembled on one side of the auxiliary vertical rod 8. The top of the carrying top rod 9 is fixed to the mounting seat 1, and a force guiding transmission groove 10 is provided on the inner side of the carrying top rod 9. The force guiding transmission groove 10 is slidably connected to the auxiliary vertical rod 8. A force guiding bottom rod 11 is fixed to the bottom of the auxiliary vertical rod 8. Both ends of the force guiding bottom rod 11 are slidably connected with movable connecting rods 12. The middle parts of the two movable connecting rods 12 are rotatably connected to the inner side of the mounting seat 1 through pins. An integrated rod seat 13 is fixed to one end of the movable connecting rod 12. The integrated rod seat 13 is assembled and connected to the smoke alarm 2. A long groove is provided on the inner side of the movable connecting rod 12. The long groove is slidably connected to the force guiding bottom rod 11, so as to provide a guide for the rotation of the movable connecting rod 12.

[0032] Example 2

[0033] Embodiment 1 is further optimized, specifically, as Figure 4-5 As shown, a detachable mechanism is installed between the smoke alarm 2 and the integrated rod base 13 , and the detachable mechanism is used for connecting the smoke alarm 2 and the integrated rod base 13 .

[0034] The detachable assembly mechanism includes a positioning plate 14, a circular inner groove 15, an arc-shaped clamping block 16, an arc-shaped protruding piece 17 and an anti-slip groove 18. The positioning plate 14 is fixed to one end of the integrated rod seat 13 close to the smoke alarm 2. A circular inner groove 15 is provided on one side of the smoke alarm 2 close to the integrated rod seat 13. The circular inner groove 15 is slidably connected to the positioning plate 14.

The anti-slip groove 18 is interference fit with the arc-shaped protrusion 17. The opening at one end of the inner side of the anti-slip groove 18 is larger, and the other end is smaller. When the smoke alarm 2 is rotated, the arc-shaped protrusion 17 can be passively rotated into the anti-slip groove 18, increasing the friction contact between the arc-shaped protrusion 17 and the anti-slip groove 18, and realizing the connection between the positioning plate 14 and the circular inner groove 15.

[0035] Preferably, the ends of the arc-shaped protruding piece 17 are provided with inclined surfaces. The provision of the inclined surfaces facilitates the user to rotate the smoke alarm 2 so that the anti-slip groove 18 is butted against the arc-shaped protruding piece 17 .

[0036] From the above, we can know that:

[0037] The utility model is directed to the following technical problems: In the process of using the prior art, the smoke alarm is usually fixed to the indoor ceiling by means of a mounting base and screws, that is, it is installed on a horizontal surface. When installing on an inclined or vertical mounting surface indoors, the orientation of the smoke alarm cannot be adjusted, and the air intake of the smoke alarm is in a vertical state, which results in a limited air intake range and reduced sensitivity of the smoke alarm. The technical solutions of the above-mentioned embodiments are adopted.

[0038] At the same time, the implementation process of the above technical solution is:

[0039] When in use, when the mounting base 1 is installed on an oblique or vertical surface indoors by screws, the servo motor 3 is started, and the output end of the servo motor 3 drives the mounting plate 4 and the docking joint 5 to rotate, so that the docking joint 5 moves along the inner side of the matching inner groove 7.

[0040] When the smoke alarm 2 needs to be separated from the integrated rod seat 13, the smoke alarm 2 is rotated so that the smoke alarm 2 drives the arc-shaped clamping block 16 to rotate, thereby separating the anti-slip groove 18 from the arc-shaped protruding piece 17 until the circular inner groove 15 in the smoke alarm 2 can be separated from the positioning plate 14.

[0041] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0042] 1. The utility model uses a structural design of a cooperative use mechanism to facilitate the adjustment of the angle of the smoke alarm 2. When the mounting base 1 is installed on an oblique or vertical surface, smoke can easily enter the air intake portion of the smoke alarm 2, thereby increasing the air intake range and achieving a good use effect.

[0043] 2. The utility model adopts the structural design of the detachable mechanism, so that the device can quickly disassemble and assemble the smoke alarm 2 and the integrated rod base 13, thereby improving the convenience of later disassembly and assembly.

[0044] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.
