Description

Technical Field

[0001] The present invention relates to the related field of electric actuators, and in particular to an electric actuator control system.

[0002] panel. Background Art

[0003] Electric actuators are widely used in the field of industrial automation, and the knobs on their control housings are an important interface for users to interact with the equipment. The knobs are used to adjust the actuator's parameter settings, such as speed, torque, or stroke. The stability of the knobs is crucial to ensure the accuracy and safety of the operation. Therefore, existing electric actuator control panel knobs often face the problem of unstable fixing, which may lead to misoperation, incorrect parameter settings, and even damage to the equipment or interruption of the production process.

[0004] Traditional knob fixing methods usually rely on threaded fastening or simple snap-on structures. These methods may perform well at the initial installation, but their fixing effect may gradually weaken over time and due to environmental factors. Utility Model Content

[0005] In order to improve the fixing effect of the knob and prevent the knob from rotating due to accidental touch, the present application provides a control panel of an electric actuator.

[0006] The control panel of an electric actuator provided in this application adopts the following technical solution:

[0007] A control panel for an electric actuator comprises a knob, one end of which is rotatably mounted on the housing, the other end of which is provided with a slide groove close to the housing, a sliding pressure block and a snap-in ball being movably arranged in the slide groove, the snap-in ball being in sliding contact with the housing, and an arcuate snap-in groove being provided on the housing corresponding to the snap-in ball, the snap-in ball being capable of being embedded in the arcuate snap-in groove; an elastic member is arranged between the sliding pressure block and the snap-in ball, one end of the elastic member is mounted on the sliding pressure block, the other end of the elastic member abuts against the snap-in ball, and the elastic member is always in a compressed state.

[0008] By adopting the above technical solution, when the knob is rotated to a specified gear position, one end of the elastic member in a compressed state acts on the sliding pressure block, and the other end applies pressure to the snap-on ball, so that the snap-on member can be smoothly embedded in the arc-surface slot matching the gear position under the action of the elastic member, thereby effectively preventing the knob from being easily rotated and improving the fixing effect of the knob. When the knob needs to be turned again, the user needs to apply a certain amount of force to turn the knob so that the snap-on ball can slide out of the arc-surface slot smoothly, and the elastic member that is always compressed can be used to turn the knob to re-embed the snap-on ball into the arc-surface slot.

[0009] Preferably, a plurality of the arc surface grooves are provided, and the plurality of the arc surface grooves are arranged along the circumferential direction of the rotation axis of the knob.

[0010] By adopting the above technical solution, multiple gear positions can be adjusted by using multiple arc-surface slots.

[0011] Preferably, limit members are provided on the housing at two ends corresponding to the rotation path of the knob.

[0012] By adopting the above technical solution, the rotation range of the knob can be limited by setting the limiter, which effectively prevents the knob from being damaged due to excessive rotation or affecting the normal operation of other components.

[0013] Preferably, the knob is provided with a locking hole matching the locking piece near the bottom of the slide slot, and the locking hole is connected to the slide slot; when the locking piece is installed in the locking hole, the sliding pressure block moves toward the bottom close to the shell.

[0014] By adopting the above technical solution and setting a lock hole, the sliding pressure block can be moved downward in cooperation with the locking member, thereby increasing the pressure of the elastic member on the locking ball. At this time, the knob is not easy to rotate, further improving the fixing effect of the knob.

[0015] Preferably, the sliding pressure block includes a sliding end and a mounting end, and the mounting end is close to the shell; one end of the elastic member away from the locking ball is sleeved on the outside of the mounting end and abuts against the sliding end, and the outside of the sliding end is close to or abuts against the inner wall of the slide groove.

[0016] By adopting the above technical solution, one end of the elastic member can act on the sliding end, so that the elastic member can apply pressure to the caught ball.

[0017] Preferably, one end of the knob is rotatably mounted on the shell through a mounting base, and a mounting groove is provided at one end of the mounting base away from the shell, the mounting groove is provided with a limiting bolt, and the limiting bolt and the mounting groove are threadedly matched.

[0018] By adopting the above technical solution, the rotation of the knob can be achieved by providing a mounting base, and the rotation axis of the knob can be limited by using a limiting bolt.

[0019] Preferably, the connection between the arc-surface slot and the shell is configured as an arc-surface transition design.

[0020] By adopting the above technical solution, the caught ball can slide out of the arc surface slot more effortlessly.

[0021] Preferably, a label is provided on the shell corresponding to the arc-surface slot.

[0022] By adopting the above technical solution, the user can understand the function of the gear position conveniently by setting labels.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the knob is rotated to a specified gear position, one end of the elastic member in a compressed state acts on the sliding pressure block, and the other end of the elastic member applies pressure to the snap-on ball, so that the snap-on member can be embedded in the arc-surface snap-on groove corresponding to the gear position under the action of the elastic member, thereby improving the fixing effect of the knob to prevent the knob from being accidentally turned;

[0025] 2. When the knob needs to be turned, the locking ball is forced to slide out of the arc-surface slot by turning the knob with force. At this time, the elastic member is still in a compressed state and the locking ball is in sliding contact with the housing. Then, the knob can be further turned to insert it into another arc-surface slot to achieve gear adjustment.

[0026] 3. The lock hole and the locking piece used in conjunction with it are used to limit the knob after the gear adjustment is completed. At this time, the sliding pressure block moves downward and increases the pressure of the elastic piece on the clamping ball, making the knob less likely to rotate, further improving the fixing effect of the knob.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] An embodiment of the present application discloses a control panel of an electric actuator.

[0032] Reference Figure 1 and Figure 2A control panel of an electric actuator includes a knob 1, one end of which is rotatably mounted on a housing 100, and the other end of the knob 1 is provided with a slide groove 11 near the housing 100, in which a sliding pressure block 2 and a snap-in ball 3 are movably provided. The housing 100 is provided with a plurality of arc-surface snap-in grooves 5 that snap-in with the snap-in ball 3. This embodiment is illustrated by taking three as examples. The plurality of arc-surface snap-in grooves 5 are arranged along the circumferential direction of the rotation axis of the knob 1, and each arc-surface snap-in groove 5 corresponds to a different gear position of the knob 1. An elastic member 4 is provided between the sliding pressure block 2 and the snap-in ball 3, one end of the elastic member 4 is mounted on the sliding pressure block 2, and the other end of the elastic member 4 abuts against the snap-in ball 3, and the elastic member 4 is always in a compressed state. By rotating the knob 1, the snap-in ball 3 can be embedded in the arc-surface snap-in groove 5 under the action of the elastic member 4, so that the knob 1 can be prevented from being easily rotated as much as possible, thereby improving the fixing effect of the knob 1 structure.

[0033] The knob 1 is in the shape of a rectangular plate as a whole, and both ends of the knob 1 in the length direction are arc-shaped. One end of the knob 1 in the length direction is rotatably mounted on the housing 100 through the mounting base 6, and the knob 1 is provided with a through hole 12 corresponding to the mounting base 6. The mounting base 6 is in the shape of a cylinder as a whole, and the length direction of the mounting base 6 is perpendicular to the rotation plane of the knob 1. One end of the mounting base 6 in the length direction is mounted in the housing 100, and the other end of the mounting base 6 in the length direction is rotatably mounted in the through hole 12. The mounting base 6 is provided with a mounting groove 61 along its own length direction at one end away from the housing 100. A limiting bolt 7 is provided in the mounting groove 61, and the limiting bolt 7 and the mounting groove 61 are threadedly matched. Preferably, a recessed portion 13 is also provided at one end of the knob 1 corresponding to the through hole 12 away from the housing 100, so that the head of the limiting bolt 7 can be located in the recessed portion 13, thereby improving the aesthetics.

[0034] The slide groove 11 is arranged at the other end of the length direction of the knob 1. The slide groove 11 is cylindrical as a whole, and the slide groove 11 is grooved toward the bottom near the shell 100. The sliding pressure block 2 includes an integrally formed sliding end 21 and a mounting end 22, and the mounting end 22 is located on the side of the sliding end 21 close to the shell 100. The mounting end 22 is cylindrical as a whole, and the length direction of the mounting end 22 is perpendicular to the rotation plane of the knob 1. The sliding end 21 is truncated cone as a whole, and the axis of the sliding end 21 coincides with the axis of the mounting end 22. The circular surface with a larger area of ​​the sliding end 21 is close to the mounting end 22, and the diameter of the surface is larger than the diameter of the end face of the mounting end 22. The outer side of the sliding end 21 is close to or abuts against the inner wall of the slide groove 11, thereby realizing the sliding fit between the sliding pressure block 2 and the slide groove 11.

[0035] One end of the elastic member 4 is sleeved on the outside of the mounting end 22 and abuts against the side of the sliding end 21 close to the housing 100, so that the sliding pressure block 2 can compress the elastic member 4 toward the elastic member 4, and the compressed elastic member 4 can apply pressure to the snap-in ball 3, so that the snap-in ball 3 can be embedded in the arc-surface snap-in groove 5. When the snap-in ball 3 needs to be moved to another arc-surface snap-in groove 5, more force is required to turn the knob 1, and the snap-in ball 3 rotates and gradually slides out of the arc-surface snap-in groove 5. At the same time, the spring is still in a compressed state, and during the rotation of the knob 1, the snap-in ball 3 is in sliding contact with the housing 100.

[0036] Preferably, the knob 1 is provided with a cylindrical lock hole 9 near the slide groove 11, and the lock hole 9 is used in conjunction with a locking member such as a lock head or a lock pin. The length direction of the lock hole 9 is perpendicular to the length direction of the slide groove 11. The lock hole 9 is located on the side of the slide groove 11 away from the housing 100, and is connected to the slide groove 11. When the locking member is not installed, the portion of the sliding end 21 away from the housing 100 is located in the lock hole 9. When the knob 1 is rotated until the snap-in ball 3 is embedded in the designated arc-shaped snap-in groove, the sliding pressure block 2 can be moved toward the bottom close to the housing 100 by installing the locking member, thereby increasing the pressure of the elastic member 4 on the snap-in ball 3. At this time, the knob 1 is not easy to rotate.

[0037] The housing 100 is provided with limit members 8 at both ends of the rotation path of the knob 1. The limit members 8 are cylindrical in shape, and the length direction of the limit members 8 is perpendicular to the rotation plane of the knob 1. When the side wall of the knob 1 abuts against the limit members 8, the catch ball 3 is located in the catch ball 3 close to the limit members 8, thereby further limiting the rotation range of the knob 1 and ensuring that the knob 1 will not be excessively rotated to damage or affect the normal operation of other components.

[0038] On this basis, the connection between the arc surface slot 5 and the housing 100 is set to an arc surface transition design, so that the receiving ball 3 can slide out of the arc surface slot 5 more effortlessly. In addition, labels 102 such as stickers, recessed text or raised text are set on the housing 100 corresponding to different arc surface slots 5, so that users can understand the functions of each gear position easily.

[0039] In addition, a plurality of buttons 101 may be provided on the housing 100. In this embodiment, three buttons 101 are provided. The plurality of buttons 101 are provided close to the knob 1 and outside the rotation range of the knob 1 to realize more panel operation functions.

[0040] The implementation principle of the control panel of an electric actuator in the embodiment of the present application is as follows: when the knob 1 is rotated to adjust to a specified gear position, the elastic member 4 is in a compressed state, one end of the elastic member 4 acts on the sliding pressure block 2, and the other end of the elastic member 4 acts on the snap-on ball 3, so that the snap-on member can be embedded in the arc-surface slot 5 corresponding to the gear position under the action of the elastic member 4, so as to prevent the knob 1 from being easily rotated and improve the fixing effect of the knob 1. When it is necessary to rotate the knob 1, it is necessary to rotate the knob 1 with force to make the snap-on ball 3 slide out of the arc-surface slot 5. At this time, the elastic member 4 is still in a compressed state and the snap-on ball 3 is in sliding contact with the housing 100, so that the snap-on ball 3 can be embedded in other arc-surface slots 5 to achieve gear adjustment.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
