Description

Technical Field

[0001] The utility model relates to the technical field of electronic switches, in particular to a self-locking reset button switch. Background Art

[0002] As a common control component in electronic devices, push button switches are widely used in various electrical and electronic devices, such as home appliances, industrial control, and automobiles. Traditional push button switches generally only have simple on and off functions, and users need to manually operate the buttons to turn the circuit on or off. However, with the development of technology and the continuous expansion of application scenarios, the performance and functional requirements of push button switches are also getting higher and higher;

[0003] On the one hand, traditional push button switches require users to manually keep the buttons pressed after being pressed to keep the circuit connected. This design is not only cumbersome to operate, but also easily causes muscle fatigue when used for a long time, reducing the convenience and comfort of use. On the other hand, in certain specific application scenarios, such as power outages or equipment failures, traditional push button switches may not be able to return to their initial state, resulting in the circuit being unable to disconnect, thereby causing safety hazards. In addition, for some devices that require frequent switching of states, manual resetting also increases the inconvenience of operation and the possibility of errors. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a self-locking reset button switch, comprising a base, a cylindrical protrusion is arranged inside the base, and the outer end of the protrusion is connected to a first spring, the outer end of the first spring is sleeved with a contact piece, the upper end of the contact piece is connected to a rotor, and a second spring is arranged in the middle of the upper end of the rotor, the outside of the second spring is connected to a button, the upper end of the base is connected to a rubber cover, and the two sides of the base are connected to terminals, and the rotor, the button and the rubber cover are all contacted with a driving gear, and the driving gear is used to drive the rotor to rotate to drive the contact on the contact piece to connect or disconnect with the terminal, thereby realizing the on-off function.

[0006] Preferably, the base is a rectangular square plate structure, and a circular notch is provided in the middle of the upper end of the base, and through circular holes are provided at the four corners of the circular notch for connection and fixation with the rubber cover, and a cylindrical protrusion is provided inside the circular notch.

[0007] Preferably, the first spring and the cylindrical protrusion inside the base are matched and sleeved with each other, and a matching contact piece is connected to the outside of the first spring, three contacts are evenly spaced outside the lower end of the contact piece, and the contact pieces are in contact with the terminals above.

[0008] Preferably, the lower end of the contact piece is an annular circular plate structure, and circular holes are provided on the annular circular plate at equal intervals.

[0009] Preferably, the rotor is in a cylindrical sleeve structure, the rotor is connected to the top of the contact piece, and driving gears are arranged at equal intervals around the lower end of the rotor, and a column angle is arranged below the driving gear, an inclination angle is provided at the upper end of the driving gear inside the rotor, a groove is provided in the middle of the upper end of the rotor, and a second spring is arranged inside the groove.

[0010] Preferably, a button is sleeved on the outside of the second spring, and driving gears are arranged at equal intervals around the lower end of the button. A symmetrical inclination angle is opened at the lower end of the driving gear inside the button, and the driving gear arranged at the lower end of the button matches and fits with the driving gear arranged at the lower end of the rotor.

[0011] Preferably, the outer end of the rubber cover is a rectangular cube structure, the middle of the rubber cover is connected to a cylindrical sleeve, driving gears are arranged at equal intervals around the inner wall of the cylindrical sleeve, and the lower end of the driving gear inside the rubber cover is provided with an inclination angle.

[0012] The beneficial effects of the utility model are as follows: the device is engaged with each other through the mutual snap fit of the rotor and the contact sheet. When the button is pressed, the driving gear on the button starts to work, and the driving gear on the rotor is rotated through mechanical transmission. During this process, the second spring is compressed to provide the necessary rebound force for pressing the button. As the rotor rotates, the column angle at the lower end of the rotor is snapped into the circular hole on the contact sheet, and the driving gear on the rotor plays a role. The driving gear on the rubber cover is restricted to the top of the driving gear on the rotor, so that the rotor is kept in the current position. Even if the button is released at this time, the rotor will not immediately return to the initial position due to the rebound force of the first spring. Therefore, the contact on the contact sheet remains connected to the terminal, realizing the locking function, so that the device has a self-locking mechanism, which can avoid misoperation and ensure work safety; and the device can be opened and closed by a simple pressing action, without continuous pressing or multiple operations, thereby improving the convenience of device use, reducing the difficulty of operation, and allowing users to use the device more easily.

The outer end of the rubber cover 7 is a rectangular cube structure, a cylindrical sleeve is connected to the middle part of the rubber cover 7, and driving gears 9 are arranged at equal intervals around the inner wall of the cylindrical sleeve, and an inclination angle is provided at the lower end of the driving gear 9 inside the rubber cover 7.

[0021] Working principle: First, when the button 6 is pressed, the driving gear 9 on the button 6 starts to work, and the driving gear 9 on the rotor 4 is rotated through mechanical transmission. In this process, the second spring 5 is compressed to provide the necessary resilience for pressing the button 6. As the rotor 4 rotates, the column angle 901 at the lower end of the rotor 4 is snapped into the circular hole 301 on the contact piece 3, and the driving gear 9 on the rotor 4 plays a role. The driving gear 9 on the rubber cover 7 is restricted to the driving gear 9 on the rotor 4, so that the rotor 4 is kept in the current position. Even if the button 6 is released at this time, the rotor 4 will not immediately return to the initial position due to the resilience of the first spring 2. Therefore, the contact on the contact piece 3 and the terminal 8 remain connected to realize the locking function. When the switch needs to be disconnected, the user presses the button 6 again. At this time, the driving gear 9 drives the rotor 4 to rotate in the opposite direction, and the contact on the contact piece 3 is disconnected from the terminal 8 to realize the disconnection function. At the same time, due to the gradual release of the elastic force of the first spring 2, it pushes the rotor 4 back to the initial position to realize the reset function.
