Description

Technical Field

[0001] This utility model relates to the field of damper actuator technology, specifically a damper actuator with an angle adjustment structure. Background Technology

[0002] A damper is a ventilation slot installed at the port of a device or channel. It usually contains rotatable fan blades or door panels to block or adjust the speed and direction of airflow. To facilitate the operation of the fan blades inside the damper, an actuator is often installed here to adjust the fan blades.

[0003] In the past, most fan blades were directly connected to the internal worm gear. It was inconvenient to pass through the worm gear or the rotational dynamics of the fan blades on the outside of the device. It was difficult to know the rotation angle of the fan blades in the internal damper from the outside surface. The opening and closing angle of the fan blades could not be accurately known by relying solely on electronic data.

[0004] Now, a novel damper actuator with an angle-adjustable structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a damper actuator with an angle adjustment structure to solve the problem of inconvenience in identifying the fan blade angle mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a damper actuator with an angle adjustment structure, comprising a front cover and a frame, wherein the front cover is fixed to the front end of the frame, and a rear cover is fixed to the rear of the frame; a rotating block is movably connected to the lower part of the front surface of the front cover, and a pointer is fixed to the front end of the rotating block; a worm gear is movably connected to the lower part of the front end of the rear cover, and a fixing ring is welded inside the worm gear; a connecting rod is inserted into the center of the fixing ring; two sets of support blocks are fixed to the lower right corner of the front end of the rear cover, and a worm is movably connected longitudinally to the center between the support blocks; a motor is fixed between the top end of the worm and the support block; and a scale ring is provided at the lower part of the front end of the front cover.

[0007] As a further technical solution of this utility model, the bottom of the output end of the motor is fixedly connected to the worm, and the worm is meshed with the right side of the worm wheel.

[0008] As a further technical solution of this utility model, a sleeve block is fixed on both sides of the front end of the fixing ring, and a screw rod is threadedly connected to the inside of the sleeve block. A nut is threadedly connected to the surface of the screw rod. A clamping block is movably connected to the side of the screw rod, and a sponge block is fixed to the side of the clamping block. A bracket is fixed to the upper and lower parts of the inside of the fixing ring, and a sleeve plate is fixed to the front end of the bracket. A screw rod is threadedly connected between the sleeve plates, and a nut is threadedly sleeved to the upper and lower parts of the outside of the screw rod. A hole is provided between the upper and lower parts of the front end of the connecting rod.

[0009] As a further technical solution of this utility model, the screw is embedded in the hole, and the clamping block and the sponge block are symmetrically attached to both sides of the outside of the connecting rod.

[0010] As a further technical solution of this utility model, wiring rods are fixed on both sides of the top of the frame, and metal plates are movably connected to the top of the wiring rods. The surface of the metal plate is provided with a winding groove, and a round hole is provided at the center of the metal plate. A control module is installed at the front end of the back cover, and there is an electrical connection between the control module, the motor, and the metal plate.

[0011] As a further technical solution of this utility model, the metal sheet rotates horizontally at the top of the connecting rod, and the circular hole is connected to the winding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the damper actuator with an angle adjustment structure not only realizes the synchronous notification of the fan blade angle and facilitates the connection of the fan blade rod, but also prevents the wire harness from falling off;

[0013] By fixing a pointer at the front end of the rotating block, the control module inside the actuator controls the worm gear installed between the motor rotating support blocks, forcing the worm gear to mesh and push the worm wheel on the left. The connecting rod of the fan blade is locked inside the worm wheel by a fixing ring. When the worm wheel rotates, the connecting rod inside also drives the fan blade to rotate. The front end of the worm wheel is engaged adjacent to the rotating block. When the worm wheel rotates, the rotating block also rotates. The pointer in the scale ring indicates the angle of rotation of the fan blade, making it convenient for the staff to observe the rotation status of the fan blade from the outside.

[0014] By setting a hole between the upper and lower ends of the front end of the connecting rod, after opening the front cover and inserting the connecting rod into the center of the fixing ring, the sleeve is passed through the hole and screw two is installed. The screw two is tightened and reinforced. Then, screw one in the sleeve block is rotated on both sides and reinforced with nut one. The connecting rod is locked from both sides by a clamp with a sponge block. This makes it easy to install and disassemble and also prevents the connecting rod from shaking.

[0015] By using a metal plate that is movably connected to the top of the connector rod, a section of the rubber sheath of the connecting wire harness is cut off, and the internal metal wires are separately wound between the winding groove and the round hole on the surface of the metal plate. Then, tape is used to wrap the wires to prevent them from being exposed, thus preventing the wire harness from detaching from the metal plate. The metal plate can also rotate at the top of the connector rod, making it easy to adjust the connection direction of the wire harness and improving the connection strength between the wire harness and the metal plate.

The bottom of the output end of the motor 10 is fixedly connected to the worm 12, and the worm 12 is meshed with the right side of the worm gear 13.

[0023] Specifically, such as Figure 1 and Figure 2As shown, the control module 9 inside the actuator controls the motor 10 to rotate the worm gear 12 installed between the support blocks 11, forcing the worm gear 12 to mesh and push the worm wheel 13 on the left. The connecting rod 14 of the fan blade is locked inside the worm wheel 13 by the fixing ring 15. When the worm wheel 13 rotates, the connecting rod 14 inside it also drives the fan blade to rotate. The front end of the worm wheel 13 is engaged with the rotating block 7. When the worm wheel 13 rotates, the rotating block 7 also rotates. The angle of rotation of the fan blade is also indicated by the pointer 8 in the scale ring 6.

[0024] Sleeve blocks 16 are fixed on both sides of the front end of the fixing ring 15, and a screw rod 17 is connected to the inside of the sleeve block 16 by a transverse thread. A nut 18 is connected to the surface of the screw rod 17 by a thread. A clamping block 19 is movably connected to the side of the screw rod 17, and a sponge block 20 is fixed to the side of the clamping block 19. A bracket 21 is fixed to the upper and lower parts of the inside of the fixing ring 15, and a sleeve 23 is fixed to the front end of the bracket 21.

The clamping block 19 and the sponge block 20 are symmetrically attached to both sides of the outside of the connecting rod 14.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, after opening the front cover 1, once the connecting rod 14 is embedded in the center of the fixing ring 15, it passes through the sleeve 23 and the hole 25 and is fitted with the second screw 24. It is then tightened with the second nut 22 for reinforcement. Then, the first screw 17 in the sleeve block 16 is rotated on both sides and reinforced with the first nut 18. The connecting rod 14 is then locked from both sides by the clamping block 19 with the sponge block 20, making it convenient to install and remove the connecting rod 14.

[0028] Working principle: When using this utility model, firstly, cut off a section of the rubber sheath of the connecting wire harness, then separately wrap the internal metal wires between the winding groove 27 and the round hole 26 on the surface of the metal plate 5, and then wrap it with tape to prevent the metal wires from being exposed, thus preventing the wire harness from detaching from the metal plate 5. The metal plate 5 can rotate at the top of the connecting rod 4. Then, open the front cover 1, and after the connecting rod 14 is embedded in the center of the fixing ring 15, pass through the sleeve 23 and the hole 25 and install the screw 24. Tighten the screw 22 with the nut 22 for reinforcement. Then rotate the screw 17 in the sleeve block 16 on both sides, and use the same method. Nut 18 is used for reinforcement, and clamping block 19 with sponge block 20 is used to lock connecting rod 14 from both sides. Finally, the control module 9 inside the actuator controls motor 10 to rotate worm gear 12 installed between support blocks 11, forcing worm gear 12 to mesh and push worm wheel 13 on the left.
