Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve actuator technology, and in particular to a valve actuator that is easy to maintain. Background Technology
[0002] Air damper actuators are key devices used in ventilation, air conditioning, and air conditioning systems to control the opening degree of air dampers. They can convert external control signals, such as voltage and current signals, or digital signals from building automation systems, into mechanical actions, thereby precisely adjusting the opening and closing degree of the air damper blades and achieving effective control of airflow.
[0003] The protective cover of the existing damper actuator is fixed to the damper actuator with multiple screws, and the screws are distributed in a relatively scattered position. When it is necessary to maintain the internal components of the damper actuator, special tools are required to remove the screws one by one. The operation process is cumbersome and consumes a lot of time and manpower. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a valve actuator that is easy to maintain.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A maintenance-friendly damper actuator includes a damper actuator body. A removable protective cover is installed on the back side of the damper actuator body. Four grooves are provided at the four corners of the back side of the damper actuator body. A slot 1 is provided at the bottom of the groove. Limiting through grooves are provided on both sides of the inner wall of slot 1. Limiting grooves are provided on the other two sides of the inner wall of slot 1. A rotating groove is provided at the bottom of slot 1. The rotating groove is connected to the limiting through groove and the limiting groove. A slot 2 is provided at the bottom of the rotating groove. A limiting auxiliary component is provided in slot 2.
[0007] The protective cover has through holes at all four corners, and a limit component is movable inside the through holes.
[0008] In addition, a preferred structure is that the limiting auxiliary component includes a rotating disk, a magnetic sheet is rotatably disposed inside the rotating disk, and a spring is fixedly installed at the bottom of the rotating disk, with the bottom of the spring fixedly connected to the bottom of the second slot.
[0009] In addition, a preferred structure is that sliding grooves are provided on both sides of the inner wall of the second hole.
[0010] In addition, a preferred structure is that sliders are provided on both sides of the outer wall of the rotating disk, and the sliders slide within the grooves.
[0011] In addition, a preferred structure is that the limiting component includes a limiting pin, and an iron block is provided at the bottom of the limiting pin. The iron block is inserted into the rotating disk and attracts the magnetic sheet.
[0012] In addition, a preferred structure is that limit blocks are provided at both ends of the outer wall of the limit pin, and the limit blocks are engaged in the limit groove.
[0013] The beneficial effects of this utility model are as follows:
[0014] In this invention, pressing the limiting pin squeezes the spring, then rotating the limiting pin 90 degrees moves the limiting block from the limiting groove into the limiting through groove. Then, pulling the limiting component upwards quickly removes the protective cover from the main body of the air valve actuator. The operation is simple, time-saving, and labor-saving.

[0024] 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.
[0025] Reference Figure 1-8 A maintenance-friendly damper actuator includes a damper actuator body 1, a removable protective cover 2 installed on the back side of the damper actuator body 1, four grooves 11 are provided at the four corners of the back side of the damper actuator body 1, a first hole groove 12 is provided at the bottom of the groove 11, a limit through groove 121 is provided on both sides of the inner wall of the first hole groove 12, a limit groove 122 is provided on the other two sides of the inner wall of the first hole groove 12, a rotating groove 13 is provided at the bottom of the first hole groove 12, the rotating groove 13 is connected to the limit through groove 121 and the limit groove 122, a second hole groove 14 is provided at the bottom of the rotating groove 13, and a limit auxiliary component 4 is provided in the second hole groove 14;
[0026] The protective cover 2 has through holes 21 at each of its four corners, and a limit component 3 is movably installed in the through holes 21.
[0027] Meanwhile, the limiting auxiliary component 4 includes a rotating disk 41, a magnet 43 is rotatably disposed inside the rotating disk 41, and a spring 42 is fixedly installed at the bottom of the rotating disk 41. The bottom of the spring 42 is fixedly connected to the bottom of the slot 14. The magnet 43 can rotate inside the rotating disk 41, so that the limiting pin 31 can rotate after being inserted into the rotating disk 41.
[0028] Furthermore, grooves 141 are provided on both sides of the inner wall of the second hole 14.
[0029] Meanwhile, sliders 411 are provided on both sides of the outer wall of the rotating disk 41. The sliders 411 slide within the groove 141, making the up-and-down movement of the rotating disk 41 more stable.
[0030] Meanwhile, the limiting component 3 includes a limiting pin 31, and an iron block 33 is provided at the bottom of the limiting pin 31. The iron block 33 is inserted into the rotating disk 41 and attracts the magnet 43. The magnet 43 can rotate in the rotating disk 41, so that the limiting pin 31 can also rotate in the rotating disk 41.
[0031] Furthermore, limit blocks 32 are provided at both ends of the outer wall of the limit pin 31. The limit blocks 32 are engaged in the limit groove 122 to limit the limit pin 31, making it easier to install the protective cover 2 onto the main body 1 of the air valve actuator.
[0032] In this embodiment, when the damper actuator malfunctions and its internal components need to be repaired and protected, the limiting pin 31 is pressed down, which in turn compresses the spring 42 through the rotating disk 41, causing the limiting block 32 of the limiting pin 31 to leave the limiting groove 122 and enter the rotating groove 13. Then, the limiting pin 31 is rotated 90 degrees, so that the limiting block 32 is aligned with the limiting through groove 121. Then, the limiting pin 31 is loosened, and the limiting pin 31 will push the limiting block 32 into the limiting through groove 121 under the elastic action of the spring 42. At this time, the protective cover 2 can be pulled up, and the limiting block 32 of the limiting pin 31 will move upward in the limiting through groove 121 and leave the limiting through groove 121. At this time, the protective cover 2 is removed from the damper actuator body 1, and then the internal components can be maintained and repaired.
[0033] After maintenance is completed, align the limiting block 32 of the limiting pin 31 with the limiting slot 121 and insert it. Insert the bottom of the limiting pin 31 into the rotating disk 41. The iron block 33 at the bottom of the limiting pin 31 and the magnet 43 will attract each other. Then press the limiting pin 31 down so that the limiting block 32 of the limiting pin 31 enters the rotating slot 13. Then rotate the limiting pin 31 90 degrees. The magnet 43 will rotate 90 degrees synchronously with the rotating disk 41. The limiting block 32 of the limiting pin 31 will be aligned with the limiting slot 122. Then loosen the limiting pin 31. The limiting block 32 will be locked into the limiting slot 122. The protective cover 2 can then be installed on the main body 1 of the air valve actuator.
[0034] In this utility model, pressing the limiting pin 31 compresses the spring 42, then rotating the limiting pin 31 90 degrees causes the limiting block 32 to leave the limiting groove 122 and enter the limiting through groove 121. Then, pulling the limiting component 3 upwards allows the protective cover 2 to be quickly removed from the air valve actuator body 1. The operation is simple, time-saving, and labor-saving.
[0035] 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.
