Description

Technical Field

[0001] This utility model relates to the field of power switch technology, and more specifically, to a power switch with adjustable output power. Background Technology

[0002] With the rapid development of technology, electronic devices are increasingly widely used in various fields, and their types and functions are becoming more and more diversified. Different electronic devices have significantly different power requirements due to their own design and operational needs. For example, small electronic watches only require very low power to maintain their basic timekeeping function, while large industrial equipment such as CNC machine tools require higher power to ensure their normal operation. High-performance computers also require a stable and specific power supply when performing complex calculations.

[0003] Traditional power switches typically only perform simple circuit switching functions, with a fixed output power. In practical applications, this limitation leads to numerous inconveniences. In laboratory environments, researchers need to test and study electronic components or devices with varying power requirements. Using a fixed-power output power switch necessitates the use of multiple power supplies of different wattages, increasing equipment costs, consuming significant space, and reducing work efficiency. In home environments, when multiple electrical appliances are used simultaneously, such as televisions, computers, and small fans, their power demands differ. Fixed-power power switches cannot allocate power according to the actual needs of these devices, potentially causing some devices to malfunction or wasting energy.

[0004] Furthermore, in some temporary electronic equipment usage scenarios, such as outdoor electronic equipment repair and temporary exhibitions, it is difficult to quickly obtain a power supply with a power output that precisely matches the different devices, making the limitations of traditional power switches even more apparent.

[0005] Therefore, an adjustable power supply switch is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable power switch to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable power output switch, comprising a bottom shell, a top shell, and a transmission line. The top shell is mounted on the top of the bottom shell, and the transmission line for power transmission is connected to both ends of the bottom shell. A transmission assembly is installed inside the bottom shell. A pressing component is provided on one side of the transmission assembly, and multiple power-connecting components are provided on the other side of the transmission assembly. Each power-connecting component is connected to an output module. A knob is mounted on the top shell, and a rotating rod is mounted on the bottom end of the knob. A gear is mounted on the bottom end of the rotating rod, and the gear meshes with the transmission assembly.

[0008] Preferably, a rotating rod is coaxially mounted at the bottom end of the knob, and a gear that meshes with the transmission assembly is coaxially mounted at the bottom end of the rotating rod.

[0009] Preferably, the transmission assembly includes a toothed plate, a guide rod, a top head, a spring, and a pressure head. The toothed plate is meshed with a gear. A guide rod is installed at one end of the toothed plate. A top head and a pressure head are installed at both ends of the guide rod, respectively. A spring is sleeved on the guide rod near the pressure head.

[0010] Preferably, a guide block is installed inside the bottom shell, and a sliding groove is formed on the toothed plate, with the guide block slidably connected to the sliding groove.

[0011] Preferably, the extrusion assembly includes a fixed plate, movable grooves, protrusions, and locking grooves. The fixed plate is installed inside the bottom shell. A plurality of movable grooves are provided on one side of the fixed plate. A protrusion is provided on both sides of each movable groove. A locking groove is provided at the top of each protrusion.

[0012] Preferably, the power receiving assembly includes a first electrode plate and a second electrode plate. The first electrode plate is connected to the corresponding output module, and the second electrode plate is mounted on one side of the first electrode plate. The second electrode plate has a curved structure and is elastic.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By rotating the knob, the gear is driven to rotate, which in turn causes the transmission component to move under the guidance of the guide block. By using the cooperation of the pressing component and the transmission component, the electrode plates inside the power connection component are connected, allowing the output modules with different output power to be energized. The operation is simple and convenient, and the power supply can be used to supply power to equipment with different power outputs, thereby realizing the adjustment of output power.

[0015] 2. In the transmission assembly, the toothed plate meshes with the gear. During the movement of the toothed plate, the pressure head is squeezed, causing the top head to press against the electrical connection assembly. The spring can reset the top head when the pressure is removed, thereby controlling the on / off of the electrical connection assembly circuit and flexibly adjusting the output power as needed.

[0016] 3. The fixed plate of the extrusion assembly is provided with a movable groove, a protrusion and a locking groove. When the pressure head moves, the pressure of the protrusion causes the top head to abut against the power connection assembly. When it moves into the locking groove, it can limit the pressure head and ensure a stable circuit inside the power connection assembly.

[0017] 4. The second electrode of the power connection component is curved and elastic. When it is pressed against by the top head, it connects with the first electrode to realize the output module path. When the top head is removed, the connection is automatically disconnected, which facilitates circuit control. Attached Figure Description

[0024] 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.

[0025] As attached Figure 1-4The power switch with adjustable output power shown includes a bottom shell 1, a top shell 2, and a transmission line 3. The top shell 2 is installed on the top of the bottom shell 1, and the transmission line 3 for power transmission is connected to both ends of the bottom shell 1. A transmission assembly 5 is installed inside the bottom shell 1. A pressing assembly 6 is provided on one side of the transmission assembly 5, and multiple power connection assemblies 7 are provided on the other side of the transmission assembly 5. Each power connection assembly 7 is connected to an output module 8. A knob 4 is installed on the top shell 2, and a rotating rod 10 is installed at the bottom of the knob 4. A gear 11 is installed at the bottom of the rotating rod 10, and the gear 11 is meshed with the transmission assembly 5.

[0026] In practice, rotating the knob 4 causes the rotating rod 10 to drive the gear 11 to rotate, thereby causing the transmission component 5 to move under the guidance of the guide block 9 under the meshing force. During the movement, the pressure head 503 is squeezed by the compression component 6, causing the top head 505 to squeeze the electrical component 7, thereby connecting the two electrode plates in the electrical component 7, thus energizing the connected output module 8. The output power of the power supply can be changed according to the different output power of each output module 8. The operation is simple and convenient, so that the power supply can be used to transmit power to equipment with different power.

[0027] The output module 8 can be a circuit unit with different power output characteristics, such as a step-down or step-up circuit composed of resistors and capacitors of different specifications, or a chip unit with built-in different power setting programs. It can output electrical energy at the set power after being powered on, thereby realizing the adjustable output power of the power switch.

[0028] A rotating rod 10 is coaxially mounted at the bottom end of the knob 4, and a gear 11 that meshes with the transmission assembly 5 is coaxially mounted at the bottom end of the rotating rod 10.

[0029] The transmission assembly 5 includes a toothed plate 501, a guide rod 502, a top head 503, a spring 504, and a pressure head 505. The toothed plate 501 is meshed with the gear 11. A guide rod 502 is installed at one end of the toothed plate 501. A top head 503 and a pressure head 505 are respectively installed at both ends of the guide rod 502. A spring 504 is sleeved on the guide rod 502 near the pressure head 505.

[0030] A guide block 9 is installed inside the bottom shell 1, and a sliding groove 12 is provided on the toothed plate 501. The guide block 9 is slidably connected to the sliding groove 12.

[0031] In practice, when the gear 11 rotates, the toothed plate 501 is subjected to the meshing force of the gear 11. Under the guidance of the guide block 9, the toothed plate 501 can move. During the movement, the pressure head 503 is squeezed, causing the top head 503 to press against the power connection component 7. The spring 504 is compressed, thereby connecting the circuit of the power connection component 7, which enables the corresponding output module 8 to control the power transmission power. When the pressure on the pressure head 503 disappears, the potential energy of the spring 504 is released, causing the top head 505 to reset, thereby disconnecting the circuit of the corresponding power connection component 7. In this way, the output power can be adjusted as needed.

[0032] The extrusion assembly 6 includes a fixed plate 601, a movable groove 602, a protrusion 603, and a locking groove 604. The fixed plate 601 is installed inside the bottom shell 1. A plurality of movable grooves 602 are provided on one side of the fixed plate 601. A protrusion 603 is provided on both sides of each movable groove 602. A locking groove 604 is provided at the top of each protrusion 603.

[0033] In specific implementation, when the pressure head 503 is in the movable groove 602, it is not subjected to pressure. As the pressure head 503 moves, it is subjected to the pressure of the protrusion 603, which causes the top head 505 to abut against the power connection component 7. When the pressure head 503 moves into the locking groove 604, it can limit the movement of the pressure head 503 to a certain extent, so that the top head 505 can firmly abut against the power connection component 7, and the internal circuit of the power connection component 7 can be stably connected.

[0034] The power receiving assembly 7 includes a first electrode plate 701 and a second electrode plate 702. The first electrode plate 701 is connected to the corresponding output module 8. The second electrode plate 702 is installed on one side of the first electrode plate 701. The second electrode plate 702 has a curved structure and is elastic.

[0035] In practice, the second electrode 702 is subjected to the pressure of the top 505, which causes the second electrode 702 to connect with the first electrode 701, thereby forming a circuit with the corresponding output module 8 so that the power supply can transmit power at the output power of the output module 8. When the top 505 is removed, the potential energy of the second electrode 702 is released and restored, thereby automatically disconnecting the connection with the first electrode 701.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
