Description

Technical Field

[0001] This utility model relates to the field of self-locking button technology, and in particular to a self-locking button structure that prevents accidental touches. Background Technology

[0002] In the operation and control of various electronic and mechanical equipment, buttons are extremely common input components. From simple household appliances to complex industrial control systems, buttons are used everywhere. However, with the increasing number of device functions and the growing complexity of usage scenarios, traditional button structures can no longer meet people's needs for operational safety, convenience, and reliability. Therefore, developing a button structure with anti-accidental touch and self-locking functions is of great practical significance. It can not only improve the user experience of the device, but also reduce the potential risks and losses caused by misoperation, and has broad application prospects in many fields.

[0003] In existing technologies, common button structures are mainly based on simple press-type designs, generally consisting of a keycap, a spring element, and a contact switch. When the keycap is pressed, the spring element is compressed, and the keycap drives the contact switch to close, thereby realizing the conduction of the circuit or the transmission of signals. After the keycap is released, the spring element returns to its original state, and the contact switch opens. Some buttons also use the principle of limit switches, triggering the corresponding movement by the displacement of the button.

[0004] Although existing button structures can meet basic operational needs to a certain extent, they are prone to accidental activation in actual use. Traditional buttons can usually be triggered with only a small amount of external force. In some complex operating environments, such as accidental collisions with the equipment or accidental touches by the operator, buttons can easily be triggered incorrectly, leading to abnormal operation of the equipment or execution of incorrect commands. This not only affects the normal use of the equipment but also poses safety hazards. Especially in fields such as industrial control and medical equipment where high accuracy and safety are required, accidental activation can have serious consequences. Therefore, a self-locking button structure to prevent accidental activation is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-7This utility model provides an embodiment of a self-locking button structure to prevent accidental touches, including a housing 3, which serves as a support and protective component for the entire button 1 structure, providing a stable installation space for internal components. The housing 3 is made of high-strength plastic, possessing good impact resistance and durability, effectively protecting the internal structure from external physical damage. A button 1 is slidably connected inside the housing 3. The button 1 consists of a keycap and a key stem, with a frosted surface to increase friction between the finger and the button 1, facilitating precise user operation. The key stem is cylindrical and integrally formed with the keycap, ensuring the stability of button 1 operation. The button 1 can slide flexibly back and forth within the housing 3 to switch between different function states. A toggle switch 5 is rotatably connected inside the housing 3. The toggle switch 5 is elliptical in shape, with anti-slip textures on its surface, making it easy for the user to pinch and rotate it with their fingers. A limiting block 11 is fixedly connected to the inner wall of the toggle switch 5. The limiting block 11 is cuboid in shape, made of plastic, and possesses a certain degree of elasticity and wear resistance. The limiting block 11 contacts one side of the button 1. Its function is to firmly hold the button 1 in place when it is locked, preventing accidental sliding and thus avoiding misoperation. The limiting block 11 contacts one side of the button 1. An unlocking display block 6 and a locking display block 7 are fixedly connected to the top of the button 1. Both the unlocking and locking display blocks 6 are square thin pieces made of red and green plastic respectively, with bright colors for easy user identification. A display frame 8 is provided inside the outer casing 3. The top of the locking display block 7 is located at the bottom of the display frame 8, and the top of the unlocking display block 6 is located at the bottom of the display frame 8. The locking and unlocking display blocks 7 are different colors for display purposes. The current status is displayed. The tops of the locked display block 7 and the unlocked display block 6 are both located at the bottom of the display frame 8. When the button 1 is in different states, the corresponding display block will display the corresponding color in the display frame 8 to intuitively show the current status of the button 1. An unlocking spring 2 is set inside the housing 3. One end of the unlocking spring 2 is fixedly connected to the outer wall of the button 1, and the other end of the unlocking spring 2 is fixedly connected to the inside of the housing 3 for pressing the button 1. A reset spring 4 is set inside the housing 3. One end of the reset spring 4 is fixedly connected to the inner wall of the toggle 5, and the other end of the reset spring 4 is fixedly connected to the inner wall of the housing 3. A limit groove 9 is opened inside the housing 3, and a hook 10 is set inside the housing 3. The outer wall of the hook 10 is set inside the limit groove 9.

[0033] Specifically, the anti-accidental-touch self-locking button 1 structure effectively prevents accidental operation, providing users with a convenient and safe user experience. In the initial state, the return spring 4 pops out, pushing the limiting block 11 at the front of the toggle 5 to firmly press against the end of the button 1, achieving a secure self-locking function. At this time, the locking display block 7 moves to the bottom of the display frame 8, displaying a prominent green indicator to remind the user that the button 1 is in a locked state and cannot be pressed at will, greatly reducing the risk of accidental touch. When the button 1 needs to be used, simply toggle the toggle 5. The rotation of the toggle 5 will cause the limiting block 11 to move, separating it from the button 1 and releasing the restriction on the button 1. Then, the unlocking spring 2 rebounds, pushing the button 1 to move inward, while simultaneously moving the unlocking display block 6 to the bottom of the display frame 8. A red indicator shows that the button has been successfully unlocked. At this time, the user can freely press button 1 to operate. After use, if you want to lock button 1 again, simply pull button 1. The reset spring 4 will pop out, so that the limiting block 11 will contact the outer wall of button 1 again to complete the locking. At the same time, the locking display block 7 will return to the bottom of the display frame 8 to show the locked state. In addition, the limiting groove 9 and hook 10 added to the bottom of the outer shell 3 make it easy to tightly assemble the various parts of the device into a whole. This not only improves the assembly efficiency, but also enhances the stability and applicability of the structure. This anti-accidental touch self-locking button 1 structure solves the problem of easy accidental operation of traditional button 1, improves the safety and convenience of use, and improves the overall applicability and reliability through optimized assembly design.

[0034] Working principle: When button 1 needs to be used, the toggle switch 5 can be turned. The rotation of the toggle switch 5 drives the limiting block 11 to move, thereby separating it from button 1 and releasing the limitation on button 1. Then, the unlocking spring 2 rebounds, causing button 1 to move inward. At the same time, the unlocking display block 6 moves to the bottom of the display frame 8, displaying the unlocked state, and then button 1 can be pressed for use. Subsequently, when it is necessary to lock it, button 1 is pulled. The return spring 4 pops out, moving the limiting block 11 to contact the outer wall of button 1 and locking it. At the same time, as button 1 is pulled out, the locking display block 7 moves to the bottom of the display frame 8 to display the locked state, which is convenient for users to check. The device can also be assembled through the bottom limiting groove 9 and the hook 10, improving its applicability.
