Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet accessories technology, and in particular to a push button switch for electrical cabinets with locking and self-resetting functions. Background Technology

[0002] In electrical cabinet control systems, push-button switches are commonly used control components. Traditional push-button switches typically only have simple pressing operation functions, and still have some shortcomings in practical use. For example, push-button switches lack a locking function; during electrical cabinet operation, vibration, accidental touches, etc., can easily cause the button's state to change, leading to abnormal operation of electrical equipment and affecting its stability and safety. Furthermore, the reset function of push-button switches is not reliable enough, with slow or inaccurate reset speeds, failing to meet the needs of rapid and precise control. Moreover, the structural design of traditional push-button switches is often complex, making repair and component replacement difficult, increasing maintenance costs and time. These problems limit the further development and application of push-button switches in the field of electrical control. Therefore, developing a push-button switch for electrical cabinets with reliable locking and self-reset functions, a reasonable structure, and easy maintenance is of significant practical importance. Utility Model Content

[0003] To address some of the problems existing in the prior art, this utility model provides a push button switch for electrical cabinets with locking and self-resetting functions. Through ingenious structural design, this push button switch achieves both locking and self-resetting functions, while also being easy to maintain, greatly reducing maintenance costs and time, and improving the service life and practicality of the push button switch.

[0004] To achieve the above objectives, this utility model provides a push button switch for electrical cabinets with locking and self-resetting functions, including a push button switch body. The push button switch body includes a fixed base, and a reset component is connected and installed at the lower end of the fixed base. A base plate is snapped onto the bottom end of the reset component. A pressing component is provided on the fixed base, and the pressing component is connected to the reset component. A locking buckle is also provided on the side end of the fixed base.

[0005] When this utility model is in operation, firstly, the user directly presses the outer cover 101. The outer cover 101 transmits pressure to the switch guide rail 106 through the fixing ring 102, the washer ring 103, and the lock nut 104. Under the action of force, the switch guide rail 106 moves along the switch guide rail sleeve 108, and the main spring assembly 107 is compressed. At the same time, the movement of the pressing assembly 1 is transmitted to the reset assembly 4, which pushes the contact sensing mechanism 406 to act synchronously. The contact stabilizing bracket 4060 in the contact sensing mechanism 406 drives the connecting plate 4061, the locking block 4063, and the mounting plate. The paddle 4068 moves within the paddle slot 4064, causing the contact blocks 4067 at both ends of the paddle 4068 to contact the sensing block 407, thus completing the circuit. If it is necessary to lock the button switch at this time, the locking buckle 2 can be inserted, and the button can be locked by connecting it to the fixing base 5 through the elastic buckle. When the outer cover 101 is released, the main spring assembly 107 rebounds, and at the same time, the reset spring 4065 and the tension spring 4069 also play a role, causing the paddle 4068 to reset, the contact blocks 4067 to separate, thus breaking the circuit, and the button switch returns to its initial state.

[0006] The beneficial effects of this utility model are as follows: In terms of locking function, the locking buckle and the fixing seat are connected by an elastic buckle, which can effectively lock the state of the button switch and avoid button malfunctions caused by vibration, accidental touch, etc., greatly improving the stability and safety of electrical equipment operation and reducing equipment failures and production accidents caused by button malfunctions; In terms of self-resetting function, the reset component has a clever structural design, and through the coordinated work of various components, the button can be reset quickly and accurately, meeting the requirements of electrical cabinet control systems for fast button response and precise control; In addition, the locking block, lever, contact block and tension spring in the contact sensing mechanism can be disassembled and replaced individually, greatly reducing maintenance costs and maintenance time, improving the service life and practicality of the button switch, and has broad application prospects.

[0009] As a further improvement to this utility model, in order to enhance the flexibility, accuracy, and maintainability of the contact sensing mechanism, improve the response speed of the push-button switch, and extend its service life, the contact sensing mechanism includes a contact stabilizing bracket, on which a connecting plate is slidably mounted; a locking block is fitted on the connecting plate, and multiple fastening screws are provided on the locking block; the locking block is connected to the connecting plate by the multiple fastening screws, and the locking block can be disassembled and replaced individually; a return spring is also fitted at the lower end of the connecting plate.

[0010] As a further improvement of this utility model, in order to improve the contact sensing accuracy of the push-button switch, enhance the accuracy of contact sensing, and make the operation of the push-button switch in the electrical cabinet control more reliable, the contact sensing mechanism also includes a lever with a tension spring on it; the connecting plate and the locking block are both provided with lever slots, and several lever slots are correspondingly provided; the connecting plate is provided with a through hole, and the lever passes through the through hole and is fixed in the lever slot; contact blocks are also provided at both ends of the lever, and contact sensing is performed through the contact blocks.

[0011] As a further improvement of this utility model, in order to optimize the disassembly and replacement process of the contact sensing mechanism, reduce maintenance costs and difficulties, and improve maintainability and economy, the overall card block is T-shaped, and the height of the mounting groove on one side of the through hole formed between the card block and the connecting plate is 1.2 to 1.5 times the outer diameter of the tension spring; the paddle, contact block and tension spring can all be disassembled and replaced individually.

[0012] As a further improvement of this utility model, in order to effectively prevent the button from malfunctioning due to vibration of the electrical cabinet or other unexpected situations, and to enhance the safety and stability of the button switch; at the same time, while ensuring reliable locking, it is convenient for users to unlock at any time as needed; the locking buckle and the fixing base are connected by an elastic buckle, and the locking buckle is used to lock the button switch state.
