Description

Technical Field

[0001] This utility model relates to the technical field of fire damper actuators, specifically a fire damper actuator with a quick-change temperature sensor. Background Technology

[0002] A fire damper is a type of valve that uses shape memory alloy to control temperature and closes by gravity and a spring mechanism. Newer products also utilize the deformation of shape memory alloy to close the valve. The temperature sensor inside the fire damper is a very important detection element, and it may need to be disassembled and replaced during inspection and maintenance to ensure the normal operation of the fire damper.

[0003] Currently, fire damper actuators mainly use the housing as an external protective installation structure. During maintenance, the housing of the actuator needs to be opened to replace the temperature sensor, which is very inconvenient. Some fire dampers allow for quick replacement by opening the top of the temperature sensor, but the sealing effect at the opening is poor and the sealing structure is easy to detach from the housing, affecting normal use.

[0004] There is an urgent need for a fire damper actuator that allows for quick replacement of the temperature sensor to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a fire damper actuator that allows for quick replacement of the temperature sensor, thereby solving the problem of inconvenient and slow replacement of the temperature sensor mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire damper actuator with a quick-change temperature sensor, comprising a base, a housing mounted on the top of the base, a top cover mounted on the top of the housing, a reserved opening on the left side of the top of the top of the top cover, a limiting slide fixedly connected to the rear end of the reserved opening on the surface of the top cover, a sealing plug installed inside the reserved opening, a limiting plate movably connected to the top of the sealing plug, and magnetic suction pieces fixedly connected to the top of the limiting plate and the inner side of the limiting slide.

[0007] As a further technical solution of this utility model, a temperature sensor body is installed on the base, and the reserved opening is located directly above the temperature sensor body.

[0008] As a further technical solution of this utility model, the limiting plate can be embedded inside the limiting slide and magnetically connected to the limiting slide.

[0009] As a further technical solution of this utility model, a handle shaft is movably connected to the right side of the top of the upper cover, and a handle grip is fixedly connected to the end of the handle shaft. A wiring tube is installed on the right side of the outer shell. Mounting seats are fixedly connected to the front and rear ends of the base. Mounting plates are connected to the outside of the mounting seats. Mounting holes are provided at the bottom of the mounting plates. Connecting bolts are provided at the front end of the mounting plates. Connecting holes are evenly opened on the mounting seats. The handle shaft and the handle grip are combined to form a "Z" shape.

[0010] As a further technical solution of this utility model, an anti-slip sleeve is installed on the outside of the handle grip, and the anti-slip sleeve is made of rubber.

[0011] As a further technical solution of this utility model, the mounting plate is L-shaped, and the connecting bolt is embedded in the connecting hole and installed on the mounting base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the fire damper actuator with quick temperature sensor replacement not only realizes the function of easy and quick temperature sensor replacement, easy and stable pushing and status observation, but also the function of easy and flexible installation;

[0013] The actuator cover is equipped with a pre-reserved opening, a limiting slide, a limiting plate, a sealing plug, and a magnetic chuck. The pre-reserved opening is located directly above the temperature sensor body. The pre-reserved opening is sealed by the sealing plug. The limiting plate on the sealing plug is embedded inside the limiting slide to position the sealing plug. When the temperature sensor body needs to be replaced, the limiting plate is rotated to move it out of the limiting slide, and then the sealing plug is pulled upward to expose the temperature sensor body for easy replacement. Since the limiting slide and the limiting plate are attracted by the magnetic chuck, manual force is required to rotate and move them out. Therefore, the installation of the sealing plug is very stable. This structure enables the function of quick and easy replacement of the temperature sensor.

[0014] The actuator features a curved handle shaft, a handle grip, and an anti-slip sleeve. The handle shaft and handle grip are combined to form a "Z" shape. When the handle shaft is pushed, the anti-slip sleeve can improve the anti-slip effect and enhance the stability of the push. The Z-shaped handle allows the user to intuitively observe whether the actuator is in the open state. This structure realizes the function of easy and stable push and quick observation of the opening and closing state.

[0015] The mounting plate, which includes a mounting base, connecting holes, mounting piece, mounting holes, and connecting bolts, can be used to install the actuator. The mounting position of the mounting piece can be adjusted according to installation requirements. Before installation, the mounting piece is first installed in a suitable position on the mounting base and then locked in place with the connecting bolts. Then, the actuator can be installed and fixed by engaging the mounting holes on the mounting piece with the bolts. This structure enables convenient and flexible installation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-4 An embodiment of this utility model provides a fire damper actuator with a quick-change temperature sensor, comprising a base 1, a housing 2 mounted on the top of the base 1, a top cover 3 mounted on the top of the housing 2, a reserved opening 4 on the left side of the top of the top of the top of the top cover 3, a limiting slide 12 fixedly connected to the surface of the top cover 3 at the rear end of the reserved opening 4, a sealing plug 14 installed inside the reserved opening 4, a limiting plate 13 movably connected to the top of the sealing plug 14, magnetic suction pieces 16 fixedly connected to the top of the limiting plate 13 and the inner side of the limiting slide 12, a handle shaft 5 movably connected to the right side of the top of the top of the top of the top of the top cover 3, a handle grip 6 fixedly connected to the end of the handle shaft 5, a wiring conduit 8 mounted on the right side of the housing 2, mounting seats 9 fixedly connected to the front and rear ends of the base 1, mounting pieces 11 connected to the outside of the mounting seats 9, mounting holes 15 provided at the bottom end of the mounting pieces 11, connecting bolts 17 provided at the front end of the mounting pieces 11, and connecting holes 10 evenly provided on the mounting seats 9;

[0023] The base 1 is equipped with a temperature sensor body, and the reserved opening 4 is located directly above the temperature sensor body. The limiting plate 13 can be embedded in the limiting slide 12 and is magnetically connected to the limiting slide 12.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the reserved opening 4 is located directly above the main body of the temperature sensor. The reserved opening 4 is sealed and blocked by the sealing plug 14. The limiting plate 13 on the sealing plug 14 is embedded in the limiting slide 12 to position the sealing plug 14. When the main body of the temperature sensor needs to be replaced, the limiting plate 13 is rotated to move it out of the limiting slide 12. Then, the sealing plug 14 is pulled upward to expose the main body of the temperature sensor for easy replacement. Since the limiting slide 12 and the limiting plate 13 are attracted by the magnetic absorbing piece 16, manual force is required to rotate and move them out. Therefore, the installation of the sealing plug 14 is very stable.

[0025] The handle shaft 5 and the handle grip 6 are combined to form a "Z" shape. The handle grip 6 is equipped with an anti-slip sleeve 7, which is made of rubber.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the handle shaft 5 and the handle grip 6 are combined to form a "Z" shape. When the handle shaft 5 is pushed, the anti-slip sleeve 7 can improve the anti-slip effect and enhance the stability of the push. The Z-shaped handle makes it easy for users to intuitively observe whether the actuator is in the open state.

[0027] The mounting plate 11 is L-shaped, and the connecting bolt 17 is embedded in the connecting hole 10 and mounted on the mounting base 9;

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the mounting plate 11 can be used to install the actuator. The installation position of the mounting plate 11 can be adjusted according to the installation requirements. Before installation, the mounting plate 11 is installed in a suitable position on the mounting base 9 and locked and fixed with the connecting bolt 17. Then, the actuator can be installed and fixed by cooperating with the bolt through the mounting hole 15 on the mounting plate 11.

[0029] Working principle: In use, the mounting plate 11 can be used to install the actuator. The handle shaft 5 and the handle grip 6 combine to form a "Z" shape. When pushing the handle shaft 5, the anti-slip sleeve 7 can improve the anti-slip effect and enhance the stability of pushing. The Z-shaped handle allows the user to intuitively observe whether the actuator is in the open state. The reserved opening 4 is located directly above the temperature sensor body. The reserved opening 4 is sealed and blocked by the sealing plug 14. The limiting plate 13 on the sealing plug 14 is embedded in the limiting slide 12 to achieve the positioning of the sealing plug 14. When the temperature sensor body needs to be replaced, the limiting plate 13 is rotated. 3. Move it out of the limiting slide 12, and then pull out the sealing plug 14 to expose the temperature sensor body for easy replacement. Since the limiting slide 12 and the limiting plate 13 are attracted by the magnetic 16, manual force is required to rotate and move it out. Therefore, the installation of the sealing plug 14 is very stable. When adjusting the installation position, the mounting plate 11 is installed in the appropriate position on the mounting base 9 and locked with the connecting bolt 17. Then, the actuator can be installed and fixed by cooperating with the bolt through the mounting hole 15 on the mounting plate 11. This structure realizes the function of easy and flexible installation.
