Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a switch structure for a pressure switch. Background Technology

[0002] Air compressors typically use an air pressure switch to control their operating status. The air pressure switch includes a manual start / stop button, an operating lever, and a pressure control device. To turn on the air compressor, pull up the manual start / stop button, disengaging it from the operating lever. The lever then springs back up under spring pressure, and the pressure control device automatically controls the motor to operate intermittently based on the pressure in the air tank. To turn off the air compressor, press down the manual start / stop button. The upper end of the operating lever contacts the button and, under its action, overcomes the spring force, moving downwards and remaining in the closed position.

[0003] For example, patent CN212514762U discloses a vertical pressure switch housing. A voltmeter is installed on one side of the top of the housing body. One end of the voltmeter has an opening with a mounting hole. A button is installed next to the mounting hole. A buffer spring groove is located below the button and is fixed to the inner surface of the housing body. The button is fixed to the housing body by the buffer spring groove. A circuit board is located below the voltmeter. The position of the button is controlled by the gripper-like buffer spring groove. The tightness of the buffer spring groove affects the force required to press down or pull up the button. If it is too loose, the button will automatically spring back up; if it is too tight, the button will be difficult to pull up.

[0004] Therefore, the difficulty in using the button of the pressure switch is precisely the technical problem that this application aims to solve. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention proposes a pressure switch structure that uses a lever principle to control the up-and-down movement of the driven component, thereby driving the opening and closing of the contact switch, making operation more convenient.

[0006] The technical solution of this utility model is as follows:

[0007] A pressure switch has a switching structure comprising a rotating rod, a driven member, and an elastic member, wherein the elastic member is disposed within a switching groove in a switch housing.

[0008] The bottom of the switch slot has a through hole for the follower to pass through. The follower passes through the elastic element below and extends to the through hole. The upper part of the follower is used to abut against the upper end of the elastic element.

[0009] The rotating rod is positioned above the driven member and is rotatably connected to the switch housing via a rotating shaft. The rotating rod includes a toggle part, a release part, and a stop part. The release part is closer to the rotating shaft than the stop part, and the toggle part extends away from the rotating shaft. The toggle part is used to drive the release part and the stop part to rotate along the rotating shaft, thereby controlling the release part or the stop part to contact the driven member, causing the driven member to move up and down.

[0010] In summary, the above technical solution has the following beneficial effects: the rotating rod is controlled to rotate around the rotating shaft by the toggle part; the driven member is subjected to an upward force under the action of the elastic member; when the control release part and the driven member collide, because the release part is close to the rotating shaft, the driven member moves upward and closer to the rotating shaft under the action of the elastic member; when the control contact part and the driven member collide, because the contact part is away from the rotating shaft, the driven member compresses the elastic member and moves downward and away from the rotating shaft. A contact switch that cooperates with the driven member is provided in the through hole inside the switch housing. The contact switch achieves the closing or opening of the contacts by the up and down movement of the driven member. Compared with existing buttons, this application adopts the lever principle. The rotation of the rotating rod can be easily controlled by the longer toggle part, and the up and down movement of the driven member can be easily achieved with the cooperation of the elastic member, realizing the purpose of switching. The switching structure of this new pressure switch has the effects of convenient operation and labor saving, and the elastic member always keeps the driven member in contact with the rotating rod, making the switching structure more stable and preventing abnormal noise during equipment operation.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0017] like Figures 1-4 As shown, a pressure switch structure includes a rotating rod 10, a driven member 20, and an elastic member 30. The elastic member 30 is disposed in a switch groove 41 opened in a switch housing 40. A through hole 42 is opened at the bottom of the switch groove 41 for the driven member 20 to pass through. The lower part of the driven member 20 passes through the elastic member 30 and extends to the through hole 42. The upper part of the driven member 20 is used to abut against the upper end of the elastic member 30. The rotating rod 10 is disposed above the driven member 20 and is rotatably connected to the switch housing 40 via a rotating shaft 50. The rotating rod 10 includes a toggle part 11, a release part 12, and abutting part 13. The release part 12 is closer to the rotating shaft 50 than the abutting part 13. The toggle part 11 extends away from the rotating shaft 50. The toggle part 11 is used to drive the release part 12 and the abutting part 13 to rotate along the rotating shaft 50, thereby controlling the release part 12 or the abutting part 13 to abut against the driven member 20, so that the driven member 20 moves up and down. The rotating rod 10 is controlled to rotate around the rotating shaft 50 by the actuating part 11. The driven member 20 is subjected to an upward force under the action of the elastic member 30. When the control release part 12 and the driven member 20 come into contact, because the release part 12 is close to the rotating shaft 50, the driven member 20 moves upward and closer to the rotating shaft 50 under the action of the elastic member 30. When the control contact part 13 and the driven member 20 come into contact, because the contact part 13 is away from the rotating shaft 50, the driven member 20 compresses the elastic member 30 and moves downward and away from the rotating shaft 50. A contact switch that cooperates with the driven member 20 is provided in the through hole 42 inside the switch housing 40. The contact switch achieves the closing or opening of the contacts by the up and down movement of the driven member 20. Compared to existing buttons, this application adopts the lever principle. The rotation of the rotating rod 10 can be easily controlled by the longer toggle part 11. With the help of the elastic element 30, the driven element 20 can be moved up and down easily to achieve the purpose of switching. The switching structure of this new pressure switch has the effect of convenient operation and labor saving. Moreover, the elastic element 30 keeps the driven element 20 in contact with the rotating rod 10, making the switching structure more stable and preventing abnormal noise during equipment operation.

[0018] The surfaces of the release part 12 and the contact part 13 that contact the driven member 20 are planes. After the plane contacts the driven member 20, the pressure from the elastic member 30 on the release part 12 and the contact part 13 is perpendicular to the plane of the release part 12 and the contact part 13, so that the rotating rod 10 is relatively stable in both states, and the driven member 20 will not automatically bounce up due to factors such as equipment vibration.

[0019] The rotating lever 10 also includes an arc-shaped transition section 14, which is located between the release section 12 and the contact section 13. The transition section 14 passes through the two planes of the arc-shaped release section 12 and the contact section 13, thereby allowing the actuating part 11 to rotate more effectively.

[0020] The angle between the plane of the release part 12 and the plane of the contact part 13 is 90 degrees. This angle is the angle at which the rotating rod 10 needs to rotate to control the switch.

[0021] The diameter of the through hole 42 is smaller than the diameter of the elastic member 30. The driven member 20 includes a support portion 21 and a telescopic portion 22. The support portion 21 is positioned above the telescopic portion 22. The support portion 21 is located above the elastic member 30 and is used to abut against the elastic member 30. The telescopic portion 22 passes through the elastic member 30 and extends to the through hole 42. The elastic member 30 is confined within the switch slot 41, thus enabling downward compression or upward bounce, and the elastic member 30 will not fall out of the through hole 42. Under the combined action of the rotating member and the elastic member 30, the telescopic portion 22 can extend and retract vertically within the through hole 42, thereby achieving the function of controlling the switch.

[0022] The upper part of the support 21 is flat, and the contact area between the support 21 and the release part 12 is smaller than the area of ​​the flat surface of the support 21.

[0023] The upper part of the support 21 is flat, and the contact area between the support 21 and the contact part 13 is smaller than the area of ​​the flat surface of the support 21. The contact areas between the release part 12 and the contact part 13 and the support 21 are both smaller than the area of ​​the flat surface of the support 21. In this way, the elastic element 30 acts evenly on the flat surface of the release part 12 and the contact part 13, making the force on the rotating rod 10 more uniform and more stable.

[0024] A friction ridge 15 is provided at the end of the actuating part 11 away from the rotating shaft 50.

[0025] The width of the actuating part 11 at the end away from the rotating shaft 50 is greater than the width at the end closer to the rotating shaft 50. The end of the actuating part 11 away from the rotating shaft 50 is for the user to hold, and the larger width makes it easier to hold and actuate.

[0026] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
