Technical Field

[0001] This utility model relates to the field of actuator technology, and in particular to an electric fireproof valve actuator. Background Technology

[0002] An electric fire damper actuator is a device used to control electric fire dampers. It typically consists of a motor, a transmission mechanism, and a control circuit. By receiving control signals, the motor drives the transmission mechanism to open, close, or adjust the fire damper, meeting fire protection requirements in different scenarios. It effectively prevents the spread of fire and smoke during a fire, making it a crucial component for ensuring fire safety.

[0003] Currently, electric fire valve actuators rely on electrical wires for power supply and signal transmission. However, in practical applications, the wires can be accidentally pulled and detach from the actuator, leading to signal interruption and valve malfunction, posing a significant fire safety hazard and urgently requiring improvement.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 An electric fireproof valve actuator includes an actuator body 1 and a wiring port located at its lower end. A vertically arranged mounting plate 2 is fixedly connected to the lower end of the actuator body 1 for mounting a connecting plate 6. The mounting plate 2 is located behind the wiring port. A horizontally arranged baffle 3 is provided on the surface of the mounting plate 2 for shielding the connecting plate 6. The baffle 3 is located below the wiring port. Both the baffle 3 and the mounting plate 2 are made of stainless steel to improve the protection strength. A semi-circular handle 4 is fixedly connected to the surface of the baffle 3 for easy unscrewing by the user. A hinge is provided at the left end of the baffle 3 for supporting the baffle 3. The baffle 3 is rotatably connected to the mounting plate 2 through the hinge. A locking screw 5 is inserted on the surface of the baffle 3 near the right edge for fixing the baffle 3. The baffle 3 is fixed to the mounting plate 2 through the locking screw 5.

[0022] In this embodiment, two vertically arranged connecting plates 6 are fixedly connected to the surface of the mounting plate 2 for mounting the connecting guide rod 9. The connecting plates 6 are arranged horizontally, and a set of support blocks 7 are provided on the opposite side of each of the two connecting plates 6 for supporting the wire. The number of support blocks 7 in each set is 2-4. The end of the support block 7 away from the connecting plate 6 is provided with a groove, and a longitudinally arranged roller 11 is provided in the groove to reduce the friction between the wire and the support block 7. The front and rear ends of the roller 11 are rotatably connected to connecting rods 12 for supporting the roller 11. The end of the connecting rod 12 away from the roller 11 is fixedly connected to the inner side wall of the groove. A rubber pad 13 is fixedly connected to the outer side wall of the roller 11 to prevent the surface of the wire from being worn.

[0023] In this embodiment, multiple vertically arranged guide rods 8 are slidably inserted at the opposite ends of the two sets of support blocks 7 to guide the movement of the support blocks 7. A fixing ring 10 is fixedly sleeved at the end of the guide rod 8 away from the support block 7 to improve the firmness between the guide rod 8 and the connecting plate 6. The end of the fixing ring 10 away from the support block 7 is fixedly connected to the connecting plate 6. A spring 9 is slidably sleeved on the guide rod 8 to provide elastic displacement space for the support block 7. The two ends of the spring 9 are fixedly connected to the support block 7 and the connecting plate 6, respectively.

[0024] In this embodiment, firstly, the wire is plugged into the wiring port of the actuator body 1 and securely locked. Then, the locking screw 5 is unscrewed, and the baffle 3 is smoothly unscrewed. Next, the wire is properly arranged between the two connecting plates 6 and between the two sets of support blocks 7, so that the wire is naturally bent. After completing the above operations, the baffle 3 is closed, and the locking screw 5 is tightened again to stabilize the position of the baffle 3. When the wire is accidentally pulled, its bent part will slowly straighten. During the straightening process, the wire will squeeze the support block 7, thereby driving the support block 7 to move towards the connecting plate 6. During this process, the support block 7 compresses the spring 9 to achieve elastic displacement of the wire, effectively preventing the wire from being directly detached from the actuator body 1. When the pulling ends, the spring 9 pushes the support block 7 to reset due to its own elasticity, and the support block 7 pushes the wire back to the bent state.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
