Description

Technical Field

[0001] This utility model relates to the field of power switch technology, specifically a power switch with protective function. Background Technology

[0002] The main function of a power switch is to convert direct current into alternating current by switching the circuit on and off at high speed, thereby providing one or more sets of voltages required for the transformer. A light bulb switch is a type of power switch, and its main function is to control the light bulb to turn on or off by controlling the flow of current.

[0003] A search revealed, for example, that Chinese utility model patent CN221812067U discloses an anti-accidental-touch power switch, comprising a panel with a switch button movably mounted on the front side of the panel, and an anti-accidental-touch mechanism provided on the front sidewall of the panel. The anti-accidental-touch mechanism includes a fixing box, a cylindrical rod, a horizontal guide plate, a fixing block, a mounting block, a positioning block, and a spring. The fixing box is fixedly mounted on the right end of the front sidewall of the panel, the cylindrical rod is movably mounted inside the fixing box, a horizontal guide plate is fixedly mounted on the bottom of the cylindrical rod, a fixing block is fixedly mounted inside the fixing box, a mounting block is fixedly mounted on the outer surface of the cylindrical rod, a positioning block is fixedly mounted inside the fixing box, and a spring is sleeved on the outer surface of the cylindrical rod. This anti-accidental-touch power switch, by setting the anti-accidental-touch mechanism, allows the fixing block to be located inside the fixing hole, fixing the switch button and preventing accidental contact that could cause the light bulb to turn off.

[0004] This patent prevents accidental activation by fixing a block into the fixing hole of the switch button, but it has the drawback of low efficiency in emergency operation. The structure requires the user to complete three consecutive actions of "pulling-turning-releasing" and relies on the smooth cooperation of mechanical parts. In emergency scenarios (such as when a sudden accident occurs at night and the light needs to be turned on quickly), the operation is easily delayed or even impossible to complete due to hand slippage, part jamming, or insufficient force. It is difficult to meet the core requirements of "fast and reliable" switch operation in emergency situations. Therefore, a power switch with protective function is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a power switch with protective functions, which has the advantages of quickly and reliably achieving switch limit and unlocking. It solves the problem that existing technologies are prone to operation delays or even failures in emergency scenarios due to hand slippage, component jamming, or insufficient force, making it difficult to meet the core requirements of "fast and reliable" switch operation in emergency situations.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power switch with protective function, comprising a power switch body, an on / off switch on the front side of the power switch body, and a protective component on the right side of the on / off switch;

[0007] The protective assembly includes a housing. The housing is fixedly installed on the front side of the power switch body. Inside the housing, from top to bottom, a power module, a control circuit board, and a miniature electric telescopic rod are arranged sequentially. The telescopic end of the miniature electric telescopic rod passes through the bottom of the housing and is fixedly installed with a movable plate. A locking block is fixedly installed on the top of the movable plate. A button is provided on the front side of the housing.

[0008] Furthermore, the bottom of the switch is provided with a locking socket, and the locking socket is compatible with the locking block.

[0009] Furthermore, a guide block is fixedly installed on the rear side of the movable plate, and a guide groove is provided on the front side of the power switch body, with the guide block slidably connected to the guide groove.

[0010] Furthermore, a locking status indicator light and a button are provided on the front side of the housing, and the button is electrically connected to the miniature electric telescopic rod.

[0011] Furthermore, a power indicator light is provided on the top of the housing, and a charging port is provided on the right side of the housing, with a sealing cover provided at the charging port.

[0012] Furthermore, the housing is made of an insulating and flame-retardant material.

[0013] Furthermore, the power module is electrically connected to the control circuit board, and the control circuit board is electrically connected to the button and the miniature electric telescopic rod, respectively.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This power switch with protective features can quickly insert a locking block into the locking socket without complicated operations, thus limiting the power switch and effectively preventing accidental operation. In emergency situations, users only need to press the button to quickly control the miniature electric telescopic rod to remove the locking block from the locking socket, allowing the power switch to resume operation quickly. This meets the core requirements of "fast and reliable" switch operation in emergency situations. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-5 In this embodiment, a power switch with protective function includes a power switch body 1, a switch key 2 is provided on the front side of the power switch body 1, and a protective component 3 is provided on the right side of the switch key 2.

[0024] The switch 2 is used to control the power supply. Users can control the circuit to close and open by pressing the switch 2, thereby controlling the working status of the electrical equipment. The locking socket 201 at the bottom is compatible with the locking block 36 in the protective component 3. Under the action of the protective component 3, the locking block 36 can be inserted into the locking socket 201 to limit the switch 2 and prevent the switch 2 from being accidentally touched and causing misoperation.

[0025] The protective component 3 includes a housing 31. The housing 31 is fixedly installed on the front side of the power switch body 1. Inside the housing 31, from top to bottom, there are a power module 32, a control circuit board 33, and a miniature electric telescopic rod 34. The telescopic end of the miniature electric telescopic rod 34 passes through the bottom of the housing 31 and is fixedly installed with a moving plate 35. A locking block 36 is fixedly installed on the top of the moving plate 35. A button 302 is provided on the front side of the housing 31.

[0026] The protective component 3 is the key part of this utility model to achieve the protective function. The housing 31 is made of insulating and flame-retardant material, which provides a safe housing space for internal electronic components such as the power module 32, control circuit board 33 and miniature electric telescopic rod 34, avoiding interference and physical damage to the components from the external environment. At the same time, the insulating and flame-retardant properties also improve the safety during use. The power module 32 is electrically connected to the control circuit board 33, providing a stable power supply to the control circuit board 33 and the miniature electric telescopic rod 34 and other components that require electric drive, ensuring the normal operation of each component. The control circuit board 33 is electrically connected to the button 302 and the miniature electric telescopic rod 34 respectively, playing a core control role. It receives the operation signal transmitted by the button 302, processes the signal, and then controls the working state of the miniature electric telescopic rod 34 according to the processing result.

[0027] A miniature electric telescopic rod 34 is installed inside the housing 31. Its telescopic end passes through the bottom of the housing 31 and is fixedly mounted on a movable plate 35. When the control circuit board 33 issues a command, the miniature electric telescopic rod 34 can telescopically extend and retract, thereby driving the movable plate 35 to move up and down. The locking block 36 fixedly mounted on the top of the movable plate 35 moves with the movable plate 35. When it is necessary to limit the switch 2, the miniature electric telescopic rod 34 drives the movable plate 35 to move upward, so that the locking block 36 is inserted into the locking socket 201 at the bottom of the switch 2, restricting the movement of the switch 2 and preventing accidental activation. When it is necessary to unlock the switch 2, the miniature electric telescopic rod 34 drives the movable plate 35 to move downward, so that the locking block 36 is removed from the locking socket 201, and the switch 2 can be operated normally.

[0028] To ensure the stability and accuracy of the movement of the movable plate 35, a guide block 37 is fixedly installed on the rear side of the movable plate 35, and a guide groove 38 is provided on the front side of the power switch body 1. The guide block 37 is slidably connected to the guide groove 38. The guide block 37 slides in the guide groove 38, which guides and limits the movement of the movable plate 35, ensuring that the movable plate 35 can only move up and down in the set direction, thereby ensuring that the locking block 36 can be accurately inserted into or removed from the locking socket 201.

[0029] The button 302 on the front of the housing 31 is electrically connected to the miniature electric telescopic rod 34. The user sends an operation signal to the control circuit board 33 by pressing the button 302. After receiving the signal, the control circuit board 33 controls the miniature electric telescopic rod 34 to move, realizing the quick unlocking of the switch 2. Only a simple press of the button 302 is needed, which greatly improves the efficiency of emergency operation. The power indicator light 303 on the top of the housing 31 is used to display the power status of the power module 32, so that the user can know the remaining power in time for charging. The charging interface 304 on the right side of the housing 31 is used to charge the power module 32. The sealing cover 305 on the charging interface 304 can prevent dust, moisture and other substances from entering the charging interface 304.

[0030] In actual use, when in normal use and no protection is needed for the switch 2, the locking block 36 is located outside the locking socket 201, the locking status indicator 301 is off, and the switch 2 can be operated freely. When it is necessary to prevent accidental contact with the switch 2, no complicated operation is required. Simply control the extension of the miniature electric telescopic rod 34 to insert the locking block 36 into the locking socket 201, and the locking status indicator 301 will light up red, thus limiting the switch 2. In emergency situations, such as when a sudden accident occurs at night and the light needs to be turned on quickly, the user only needs to press the button 302 quickly. After receiving the signal, the control circuit board 33 will immediately control the miniature electric telescopic rod 34 to shorten, causing the locking block 36 to quickly exit from the locking socket 201. The locking status indicator 301 will then turn off, and the switch 2 can immediately resume operation.

[0031] In summary, this power switch with protective function, by setting the protective component 3, can quickly insert the locking block 36 into the locking socket 201 without complicated operation, thereby limiting the switch 2 and effectively preventing accidental operation of the power switch caused by accidental contact. In emergency scenarios, the user only needs to press the button 302 to quickly control the miniature electric telescopic rod 34 to drive the locking block 36 out of the locking socket 201, so that the switch 2 can quickly resume operation, meeting the core requirements of "fast and reliable" switch operation in emergency situations.
