Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5This utility model provides an embodiment of an easily assembled fireproof smoke exhaust valve actuator, including an actuator housing 7, a front cover 1 installed at the front end of the actuator housing 7, a rear cover 8 fixedly connected to the rear end of the actuator housing 7, fixing plates 5 fixedly connected to the left and right sides of the upper and lower ends of the rear end of the front cover 1, mounting holes 12 are respectively opened on the left and right sides of the upper and lower ends of the fixing plates 5 and the outer side of the outer wall of the actuator housing 7, bolts 6 are installed inside the mounting holes 12, fixing blocks 9 are fixedly connected to the left and right sides of the rear end of the front cover 1, movable blocks 10 are movably hinged to the front end of the left and right sides of the actuator housing 7, a protrusion 16 is fixedly connected to the side of the movable block 10 near the outside, and a groove 15 is opened inside the fixing block 9;

[0026] The fixing plate 5 is fixed to the upper and lower ends of the actuator housing 7 by bolts 6 and mounting holes 12. The front cover 1 is installed at the front end of the actuator housing 7 by bolts 6 and mounting holes 12. The protrusion 16 is embedded in the groove 15, and the groove 15 and the protrusion 16 cooperate with each other.

[0027] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, when the front cover 1 needs to be installed on the front end of the actuator housing 7, place the front cover 1 on the front end of the actuator housing 7. When placing the front cover 1, align the mounting hole 12 on the fixing plate 5 with the mounting hole 12 on the actuator housing 7. Then screw the bolt 6 into the mounting hole 12 to limit and fix the upper and lower ends of the front cover 1. Then rotate the movable block 10 so that the protrusion 16 on the movable block 10 is locked in the groove 15 to fix the left and right sides of the front cover 1. Using the groove 15 and the protrusion 16 to fix the left and right sides of the front cover 1 can save assembly time.

[0028] A connecting rod 2 is movable at the top right side inside the front cover 1. A handle 11 is fixedly connected to the front end of the right side of the connecting rod 2. A protective sleeve 4 is provided on the outside of the handle 11. A second sealing ring 14 is provided at the connection between the front cover 1 and the actuator housing 7. A first sealing ring 13 is provided on the outside between the front cover 1 and the rear cover 8.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the protective cover 4 on the outside of the handle 11 not only makes it convenient for the user to use, but also protects the user's hands. The first sealing ring 13 can seal the connection between the rear cover 8 and the actuator housing 7, and the second sealing ring 14 can seal the connection between the front cover 1 and the actuator housing 7, ensuring that it can work normally in the event of a fire and will not malfunction due to the influence of the external environment.

[0030] A protective shell 3 is fixedly connected to the middle position of the bottom end of the actuator housing 7. Limiting clamps 20 are provided on the left and right sides inside the protective shell 3. A movable rod 19 is fixedly connected to the side of the limiting clamp 20 near the outside. A push plate 18 is fixedly connected to the front end of the movable rod 19 near the middle. Limiting springs 17 are fixedly connected to the left and right sides between the limiting clamp 20 and the protective shell 3. The limiting springs 17 are installed at the upper and lower ends of the side of the limiting clamp 20 near the outside. The movable rod 19 slides on the left and right sides inside the protective shell 3. Anti-slip pads are provided on the inner side wall of the limiting clamp 20. The limiting clamp 20 slides left and right inside the protective shell 3.

[0031] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, the limiting spring 17 can use its elasticity to clamp and limit the top of the connecting wire by the limiting clamp 20, preventing the top of the connecting wire from accidentally falling off the bottom of the actuator housing 7. The anti-slip pad on the inner side wall of the limiting clamp 20 can protect the top of the connecting wire. When it is necessary to disassemble the connecting wire, push the push plate 18 outward. The push plate 18 drives the limiting clamp 20 to move to both sides through the movable rod 19, so that the connecting wire is no longer fixed.

[0032] Working Principle: In use, the protective sleeve 4 on the outside of the handle 11 not only facilitates user operation but also protects the user's hands. The first sealing ring 13 seals the connection between the rear cover 8 and the actuator housing 7, while the second sealing ring 14 seals the connection between the front cover 1 and the actuator housing 7, ensuring normal operation during a fire and preventing malfunctions due to external environmental factors. When maintenance of the actuator housing 7 is required, the front cover 1 is disassembled. After maintenance, the front cover 1 is placed back on the front of the actuator housing 7. When placing the front cover 1, the mounting holes 12 on the fixing plate 5 are aligned with the mounting holes 12 on the actuator housing 7. Then, the bolts 6 are tightened. The upper and lower ends of the front cover 1 are fixed by screwing into the mounting hole 12. Then, the movable block 10 is rotated so that the protrusion 16 on the movable block 10 is locked in the groove 15 to fix the left and right sides of the front cover 1. Using the groove 15 and the protrusion 16 to fix the left and right sides of the front cover 1 can save assembly time. The limiting spring 17 can use its elasticity to clamp and limit the top of the connecting wire by the limiting clamp 20, preventing the top of the connecting wire from accidentally falling from the bottom of the actuator housing 7. The anti-slip pad on the inner side wall of the limiting clamp 20 can protect the top of the connecting wire. When it is necessary to disassemble the connecting wire, push the push plate 18 outward. The push plate 18 drives the limiting clamp 20 to move to both sides through the movable rod 19, so that the connecting wire is no longer fixed.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
