Abstract
Description
Technical Field
[0001] This utility model relates to the field of power switch technology, specifically a power switch designed to prevent accidental activation. Background Technology
[0002] A power switch is a device that uses a circuit to control a switching transistor to quickly turn the circuit on and off. It converts direct current (DC) into high-frequency alternating current (AC), which is then supplied to a transformer for voltage transformation, thereby generating one or more required voltages. Power switches play a crucial role in power systems.
[0003] Power switches typically control the power supply, but since they are exposed outdoors, accidental activation by operators can interfere with power supply operations and lead to safety accidents. Common power switches usually have a protective cover to prevent accidental activation, but this cover can bulge outwards from the switch, making it susceptible to impact damage and rendering it ineffective in preventing accidental activation. Therefore, we propose a power switch designed to prevent accidental activation. Utility Model Content
[0004] To address the shortcomings of existing power switches designed to prevent accidental touch, this invention provides a power switch designed to prevent accidental touch. It features an anti-touch box installed around the switch button, providing initial protection. Simultaneously, a first support plate and a second support plate are installed at the lower end of the switch button. The first support plate limits the downward movement of the second support plate, preventing damage to the anti-touch box and thus ensuring the switch's ability to prevent accidental touch. This invention solves the problems mentioned in the background section.
[0005] This utility model provides the following technical solution: a power switch to prevent accidental touch, including a mounting plate, a trigger rod movably mounted inside the mounting plate, a switch button fixedly connected to the top of the trigger rod, side plates fixedly connected to both sides of the mounting plate, a front baffle fixedly connected to the front end of the mounting plate, a slide rod movably mounted inside a sliding groove in the side plate, an anti-touch box fixedly connected to the top of the slide rod, a rotating disc movably sleeved inside the anti-touch box, and a limit pin fixedly connected to the outside of the rotating disc.
[0006] Preferably, a first support plate and a second support plate are aligned and installed between the mounting plate and the switch button, with the second support plate installed on the upper end of the first support plate, and the contact surface between the first support plate and the second support plate being arc-shaped.
[0007] Preferably, a spring is fixedly connected to the lower end of the switch button, the spring is installed between the mounting plate and the switch button, and the lower end of the trigger rod contacts an inductive switch.
[0008] Preferably, a first limiting plate is installed at the front end of the anti-touch box, and the first limiting plate is installed at the front end of the front baffle.
[0009] Preferably, a rear baffle is installed inside the rear end of the mounting plate by fastening bolts, and a second limiting plate is fixedly connected to the rear end of the anti-touch box, the second limiting plate being clamped between the side plate and the rear baffle.
[0010] Preferably, the interior of the anti-touch box has a limiting groove, and the limiting pin is movably sleeved inside the limiting groove.
[0011] Preferably, a rotating handle is fixedly connected inside the rotating disk, and the rotating handle is cross-shaped.
[0012] Compared with existing power switches designed to prevent accidental touches, this invention has the following advantages:
[0013] 1. This power switch designed to prevent accidental activation has a first support plate and a second support plate installed between the mounting plate and the switch button. The first support plate prevents the second support plate from pressing down, thus initially preventing the user from accidentally activating the switch. At the same time, the anti-touch box is fitted over the outside of the switch button, further improving the anti-accidental activation effect. Furthermore, by rotating the rotating disc, the limit pin is disengaged from the limit groove, which activates the switch. Thus, through this double protection device, the accidental activation of the switch is effectively prevented.
[0014] 2. This power switch, designed to prevent accidental touch, has a side plate mounted on the side of the mounting plate. The switch is installed inside the side plate by sliding a rod, which allows the anti-touch box to be installed outside the switch button. The front baffle limits the front end of the anti-touch box, and the rear baffle is installed at the rear end of the mounting plate, thus improving the convenience and stability of the anti-touch box installation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 An anti-accidental-touch power switch includes a mounting plate 1. A trigger rod 2 is movably mounted inside the mounting plate 1. A switch button 3 is fixedly connected to the top of the trigger rod 2. Pressing the switch button 3 causes the trigger rod 2 to contact the inductive switch, thereby controlling the power supply. Side plates 7 are fixedly connected to both sides of the mounting plate 1. A front baffle 8 is fixedly connected to the front end of the mounting plate 1, limiting the position of the front end of the anti-accident box 10. A sliding rod 9 is movably mounted inside the side plate 7 with a sliding groove. The sliding rod 9 is sleeved inside the side plate 7, improving the ease of installation of the anti-accident box 10 on the upper end of the side plate 7. The top of the sliding rod 9 is fixedly connected to the anti-accident box 10. A rotating disc 14 is movably sleeved inside the anti-accident box 10. A limit pin 16 is fixedly connected to the outside of the rotating disc 14. Rotating the rotating disc 14 causes the limit pin 16 to be sleeved inside the limit groove 17, improving the ease of removal of the rotating disc 14.
[0024] Please see Figure 6A first support plate 5 and a second support plate 6 are aligned and installed between the mounting plate 1 and the switch button 3. The second support plate 6 is installed on the upper end of the first support plate 5, and the contact surfaces of the first support plate 5 and the second support plate 6 are arc-shaped. By installing the first support plate 5 and the second support plate 6 between the mounting plate 1 and the switch button 3, in the normal state, the first support plate 5 restricts the position of the second support plate 6, that is, the switch button 3 cannot be pressed down, and the arc-shaped contact surfaces of the first support plate 5 and the second support plate 6 prevent the switch button 3 from shifting due to shaking, etc. When it is necessary to control the switch, rotate the switch button 3. The switch button 3 moves the second support plate 6 away from the upper part of the first support plate 5, which controls the switch button 3 to be pressed down, thus avoiding the problem of accidentally touching the first support plate 5.
[0025] Please see Figure 6 A spring 4 is fixedly connected to the lower end of the switch button 3. The spring 4 is installed between the mounting plate 1 and the switch button 3, and the lower end of the trigger rod 2 contacts the inductive switch. The spring 4 is installed between the mounting plate 1 and the switch button 3. The spring 4 pushes the switch button 3 to move upward. When the switch button 3 is pressed downward, the switch button 3 controls the trigger rod 2 to contact the inductive switch, which can activate the function of the control switch. At the same time, when the switch button 3 is released, the switch button 3 can be reset under the action of the spring 4.
[0026] Please see Figure 2 The front end of the anti-touch box 10 is equipped with a first limiting plate 11, which is installed at the front end of the front baffle 8. The anti-touch box 10 is installed on the upper part of the mounting plate 1. The sliding rod 9 is slid into the side plate 7, which can drive the anti-touch box 10 to be sleeved on the upper part of the switch button 3. At the same time, the front baffle 8 is rotated to limit the movement trajectory of the anti-touch box 10.
[0027] Please see Figure 2 A rear baffle 13 is installed inside the rear end of the mounting plate 1 by fastening bolts. A second limiting plate 12 is fixedly connected to the rear end of the anti-touch box 10. The second limiting plate 12 is clamped between the side plate 7 and the rear baffle 13. After the anti-touch box 10 is installed on the upper end of the mounting plate 1, the rear baffle 13 is installed at the rear end of the mounting plate 1. The rear baffle 13 limits the position of the second limiting plate 12, thereby improving the stability of the second limiting plate 12 when it is spliced at the upper end of the mounting plate 1.
[0028] Please see Figure 3The inside of the anti-touch box 10 has a limiting groove 17, and the limiting pin 16 is movably sleeved inside the limiting groove 17. By rotating the externally mounted limiting pin 16 of the rotating disc 14, the limiting pin 16 is movably sleeved inside the limiting groove 17. Rotating the rotating disc 14 causes the limiting pin 16 to engage inside the limiting groove 17, that is, the rotating disc 14 can be limited to the upper end of the anti-touch box 10. At the same time, rotating the rotating disc 14 in the opposite direction causes the limiting pin 16 to disengage from the limiting groove 17, so that the rotating disc 14 can be opened. At the same time, the switch button 3 can be operated through the hole formed inside the anti-touch box 10.
[0029] Please see Figure 4 A rotating handle 15 is fixedly connected inside the rotating disc 14. The rotating handle 15 is cross-shaped. The rotating handle 15 is installed inside the rotating disc 14. An opening is formed on the outside of the rotating disc 14 to facilitate observation of the internal status of the switch. At the same time, manually rotating the rotating handle 15 can easily drive the rotating disc 14 to rotate.
[0030] Working principle: In use, the anti-touch box 10 is installed on the upper part of the mounting plate 1. The anti-touch box 10 drives the slide rod 9 to move and fit inside the side plate 7 for installation. At the same time, a rear baffle 13 is installed at the rear end of the mounting plate 1. The rear baffle 13 drives the second limit plate 12 to lock and limit its position. Through the protection of the anti-touch box 10 and the limiting of the second support plate 6 and the side plate 7, the external protection effect of the switch button 3 is ensured, and the phenomenon of accidental touch by the user is avoided. When the device is in use, the rotating disc 14 is rotated to remove it from the anti-touch box 10. The switch button 3 is rotated and then pressed again to activate the switch.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
