TECHNICAL FIELD

[0001] The present application relates to the field of panel switch, in particular to an extendable panel switch. BACKGROUND

[0002] Switch panel is a common electrical equipment, used to control the switch of circuit and protect the circuit. It is usually composed of one or more switches, which can be used to turn on or off the circuit, and cut off the power supply when needed. Switch panel is widely used in various fields, including residential, commercial and industrial.

[0003] The switch panel of the invention disclosed in the patent with the publication number CN113921320A comprises a switch shell and a switch bottom shell, the switch shell is fixedly connected with the switch bottom shell and encloses an internal space, at least one opening is formed on the switch shell; further comprising at least one switch key, at least one protection frame and at least one silica gel block, the protection frame is a shell structure with openings at both ends, the outer peripheral wall of the protection frame is matched with the opening on the switch shell, the inner peripheral wall of the protection frame wraps the outer peripheral wall of the switch key, the protection frame and the switch key extend out of the switch shell through the opening on the switch shell from the internal space, the protection frame is fixed, and the silica gel block is arranged in the internal space and located between the switch key and the switch contact.

[0004] The switch panel of the above-mentioned technology is fixedly connected on the wall surface, when it is needed to turn on or off the circuit, it is necessary to operate in front of the switch panel, which is not convenient. SUMMARY

[0005] In order to make the use of switch more convenient, the present application provides an extendable panel switch.

[0006] The present application provides an extendable panel switch, which adopts the following technical solution: An extendable panel switch, comprising a panel base, a switch box and an extension mechanism, a placing groove is formed on the panel base, the switch box is movably connected on the placing groove, the extension mechanism is used to connect the panel base and the switch box, the extension mechanism comprises an extension line and a winding assembly, a winding box is arranged on the switch box, the extension line is wound in the winding box, one end of the extension line penetrates the winding box and is fixedly connected on the switch box, the other end of the extension line penetrates the winding box and is fixedly connected on the panel base, and the winding assembly is used to wind the extension line in the winding box.

[0007] By adopting the above technical solution, the switch box can be taken off from the panel base, the extension line in the winding box extends to the outside, within the length range of the extension line, the switch box can be taken to any place, so as to turn on or off the circuit connected by the panel switch, and facilitate the use of the panel switch.

[0008] Preferably, the winding assembly includes a winding roller, a torsion spring, and a limiting assembly. The winding roller is rotatably connected inside the winding box, and the extension wire is wound on the winding roller. The torsion spring is disposed on the winding box and is used to drive the rotation of the winding roller. The limiting assembly is used to limit the movement of the extension wire.

[0009] By adopting the above technical solution, when the extension line is pulled out, the winding roller rotates, and the torsion spring deforms when the winding roller rotates. When the torsion spring returns to its original state, the winding roller rotates in the opposite direction, causing the extension line to be rewound back onto the winding roller, and the switch box is retracted into the placement slot. The limiting component restricts the movement of the extension line, reducing the possibility of the extension line retracting.

[0010] Preferably, the winding assembly further includes a gear ring, a plurality of first gears and second gears, the second gears being fixed on the winding roller, the gear ring being coaxial with the second gears and rotatably connected inside the winding box, the plurality of second gears being rotatably connected inside the winding box respectively, the plurality of second gears simultaneously meshing with the gear ring and the second gears, one end of the torsion spring being fixedly connected to the gear ring, and the other end of the torsion spring being fixedly connected inside the winding box.

[0011] By adopting the above technical solution, the transmission ratio is changed, and the transmission is carried out through the first gear and the second gear. When the roller rotates, the gear ring drives the torsion spring to move and deform.

[0012] Preferably, the limiting component includes a slider and two limiting blocks. Multiple rubber blocks are evenly distributed along the length of the extension line. The slider is slidably connected to the winding box. One end of the slider passes through the junction box. The two limiting blocks are fixedly connected to the end of the slider located inside the junction box. When the slider slides to its limit position on one side of the extension line, the two limiting blocks abut against both sides of the extension line in the thickness direction, and the two limiting blocks are located between the two rubber blocks.

[0013] By adopting the above technical solution, the sliding slider allows the two limiting blocks to slide towards one side of the extension line until they abut against both sides in the thickness direction of the extension line, and the two limiting blocks are respectively located between the two rubber blocks, thus restricting the movement of the extension line and reducing the possibility that the switch box will automatically retract after being removed; in addition, multiple rubber blocks are provided on the extension line to reduce the possibility of damage to the extension line caused by dragging after the switch box is removed.

[0014] Preferably, the winding box is rotatably connected to the switch box.

[0015] By adopting the above technical solution, the possibility of interference in the extension line is reduced.

[0016] Preferably, the switch box is provided with a first adsorption block and a second magnetic adsorption block on both sides, and the placement slot is provided with a first magnetic adsorption block that can magnetically engage with the first adsorption block and a second adsorption block that can magnetically engage with the second magnetic adsorption block on both sides.

[0017] By adopting the above technical solution, through the magnetic connection between the first adsorption block and the first magnetic block, and the magnetic connection between the second magnetic block and the second adsorption block, the switch box is limited after it is placed back into the slot.

[0018] Preferably, it also includes an insulating sleeve, which is fitted over the outside of both the switch box and the winding box.

[0019] By adopting the above technical solution, the installation of the insulating sleeve reduces the possibility of leakage in the switch box and reduces the possibility of damage caused by dragging after the switch box is removed.

[0020] Preferably, the insulating sleeve is provided with multiple suction cups.

[0021] By adopting the above technical solution, the multiple suction cups facilitate the removal of the switch box from the placement slot and its attachment to a suitable position. This allows for the temporary placement of the switch box and enables the opening or closing of the circuit connected to the panel switch, thus facilitating the use of the panel switch.

[0022] The main technical effects of this invention are reflected in the following aspects: 1. By setting an extension component, the switch box can be removed from the panel base, and the extension wire inside the winding box extends to the outside. Within the length range of the extension wire, the switch box can be taken to any location to facilitate opening or closing the circuit connected to the panel switch, thus facilitating the use of the panel switch. 2. This invention, by setting a limiting component and sliding a slider, allows two limiting blocks to slide towards one side of the extension line until they abut against both sides in the thickness direction of the extension line, and positions the two limiting blocks between two rubber blocks, thereby restricting the movement of the extension line and reducing the possibility that the switch box will automatically retract after being removed; in addition, multiple rubber blocks are provided on the extension line to reduce the possibility of damage to the extension line caused by dragging after the switch box is removed. 3. By setting an insulating sleeve, the present invention reduces the possibility of leakage in the switch box and reduces the possibility of damage caused by dragging after the switch box is removed.

[0030] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0031] This application discloses an extendable panel switch.

[0032] Reference Figures 1-6 An extendable panel switch according to this embodiment includes a panel base 1, a plurality of switch boxes 2, and an extension mechanism 3. The panel base 1 has a placement groove 11, and the plurality of switch boxes 2 are movably connected to the placement groove 11. When the plurality of switch boxes 2 are located in the placement groove 11, the plurality of switch boxes 2 are arranged in a rectangular row. The switch boxes 2 are equipped with stationary contact plates, moving contact plates, spring plates, etc. to realize the opening and closing of the circuit. The extension mechanism 3 is used to connect the panel base 1 and the switch boxes 2. The extension mechanism 3 includes an extension wire 31 and a winding assembly 32. The winding box 22 is rotatably connected to the switch box 2 along the thickness direction of the switch box 2. The extension wire 31 is wound in the winding box 22. One end of the extension wire 31 passes through the winding box 22 and is fixedly connected to the switch box 2. The other end of the extension wire 31 passes through the winding box 22 and is fixedly connected to the panel base 1. The winding assembly 32 is used to wind the extension wire 31 in the winding box 22.

[0033] Reference Figures 1-6The switch box 2 can be removed from the panel base 1, and the extension wire 31 inside the winding box 22 extends to the outside. Within the length range of the extension wire 31, the switch box 2 can be taken to any location to facilitate the opening or closing of the circuit connected to the panel switch, thus facilitating the use of the panel switch.

[0034] Reference Figures 3-6 The winding assembly 32 includes a winding roller 321, a torsion spring 322, and a limiting assembly 33. The winding roller 321 is rotatably connected inside the winding box 22, and the extension wire 31 is wound around the winding roller 321. The torsion spring 322 is installed inside the winding box 22 and is used to drive the rotation of the winding roller 321. The limiting assembly 33 is used to limit the movement of the extension wire 31. When the extension wire 31 is pulled out, the winding roller 321 rotates. When the winding roller 321 rotates, the torsion spring 322 deforms. When the torsion spring 322 returns to its original shape, the winding roller 321 rotates in the opposite direction, causing the extension wire 31 to rewind back onto the winding roller 321 and the switch box 2 to retract into the placement slot 11. The limiting assembly 33 restricts the movement of the extension wire 31, reducing the possibility of the extension wire 31 retracting.

[0035] Reference Figures 3-6 The winding assembly 32 also includes a gear ring 323, several first gears 324 and second gears 325. The second gears 325 are coaxial and fixed on the winding roller 321. The gear ring 323 and the second gears 325 are coaxial and rotatably connected inside the winding box 22. The several second gears 325 are rotatably connected inside the winding box 22 along the rotation direction of the winding roller 321. The several second gears 325 simultaneously mesh with the gear ring 323 and the second gears 325. One end of the torsion spring 322 is fixedly connected to the gear ring 323, and the other end of the torsion spring 322 is fixedly connected inside the winding box 22. Through the above technical solution, the transmission ratio is changed, and the transmission is carried out through the first gears 324 and the second gears 325. When the winding roller 321 rotates, the gear ring 323 causes the torsion spring 322 to move and deform.

[0036] Reference Figures 3-6The limiting component 33 includes a slider 331 and two limiting blocks 332. The cross-section of the extension line 31 is square, and multiple rubber blocks 311 are provided on both sides of the extension thickness direction. The multiple rubber blocks 311 are evenly distributed along the length direction of the extension line 31. The slider 331 is slidably connected to the winding box 22 along the width direction of the extension line 31. One end of the slider 331 passes through the junction box. The two limiting blocks 332 are fixedly connected to the end of the slider 331 located in the junction box. When the slider 331 slides to the limit position on one side of the extension line 31, the two limiting blocks 332 abut against both sides of the extension line 31 in the thickness direction, and the two limiting blocks 332 are located between the two rubber blocks 311. The sliding slider 331 causes the two limiting blocks 332 to slide towards one side of the extension line 31 until they abut against both sides of the extension line 31 in the thickness direction, and the two limiting blocks 332 are respectively located between the two rubber blocks 311, which restricts the movement of the extension line 31 and reduces the possibility that the switch box 2 will automatically retract after being removed; and multiple rubber blocks 311 are fixedly connected to the extension line 31 to reduce the possibility that the extension line 31 will be damaged due to dragging after the switch box 2 is removed.

[0037] Reference Figures 1-6 The switch box 2 has a first adsorption block 23 and a second magnetic block 24 respectively embedded and fixedly connected to both sides in the width direction. The placement slot 11 has a first magnetic block 111 that can magnetically engage with the first adsorption block 23 and a second adsorption block 112 that can magnetically engage with the second magnetic block 24 respectively embedded and fixedly connected to both sides in the width direction. Through the magnetic connection between the first adsorption block 23 and the first magnetic block 111, and the magnetic connection between the second magnetic block 24 and the second adsorption block 112, the position of the switch box 2 in the placement slot 11 is limited when the switch box 2 is returned to the placement slot 11.

[0038] Reference Figures 3-6 The system also includes an insulating sleeve 4, which is fitted over the outside of both the switch box 2 and the winding box 22. The insulating sleeve 4 avoids the first magnetic adsorption block 23 and the second magnetic adsorption block 24. The insulating sleeve 4 reduces the possibility of leakage in the switch box 2 and the possibility of damage caused by dragging after the switch box 2 is removed. Multiple suction cups 41 are fixedly connected to the insulating sleeve 4, and the suction cups 41 are evenly distributed on the side of the insulating sleeve 4 away from the switch box 2. The multiple suction cups 41 facilitate the removal of the switch box 2 from the placement slot 11, allowing it to be adsorbed into a suitable position for temporary placement, facilitating the opening or closing of the circuit connected to the panel switch, and simplifying the use of the panel switch.

[0039] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods.
