Description

Technical Field

[0001] The present invention relates to the technical field of switch driving, and in particular to a driving structure of a hardware electrical appliance switch. Background Art

[0002] A switch is an electronic component that opens a circuit, interrupts current, or causes it to flow to another circuit. The most common switch is an electromechanical device operated by humans. There are many types of switches, including push-type and twist-type. Twist-type switches include rotary hardware electrical switches. In order to facilitate the operation of the switch, a drive structure needs to be added to the hardware switch. The existing series switches require individual control when in use, which brings inconvenience to the staff during operation. When all switches need to be adjusted to a synchronized position, the staff's operating steps are increased. When the switch's twisting seat is stationary, the staff's misoperation will cause the twisting seat to rotate. External factors will also cause the twisting seat to rotate, affecting the use of the switch. In addition, after the power cord is connected to the terminal, the bolts of the terminal will loosen, causing the power cord to loosen, posing a safety hazard. Summary of the Invention

[0019] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0020] Please refer to Figures 1-9 , the present invention provides a driving structure for a hardware electrical switch, including a mounting housing 1; Four twisting switches are installed inside the mounting housing 1. A twisting column is installed on the twisting switch. There are four evenly distributed wiring terminals 101 on the top of the mounting housing 1. A locking bolt is installed on the wiring terminal 101 to lock the connected power cord. Above the wiring terminal 101, a U-shaped sliding groove is provided. A locking buckle 102 is installed in the sliding groove. The sliding groove facilitates the sliding of the locking buckle 102. The locking buckle 102 is provided with two positioning grooves for positioning the locking buckle itself. There are two groups of triangular locking blocks on the inner side of the sliding groove, and there are also triangular locking blocks on the outer side of the locking buckle 102. The directions of the locking blocks of the sliding groove and the locking buckle 102 are opposite. Therefore, the locking buckle 102 is unidirectionally locked by the locking blocks. There is an extrusion inclined block at the bottom of the locking buckle 102, which contacts the locking bolt of the wiring terminal 101. After the position of the locking buckle 102 is locked, the locking buckle 102 prevents the locking bolt of the wiring terminal 101 from loosening. The locking buckle 102 is provided with a contraction groove, which is a U-shaped structure. The locking buckle 102 is deformed by force through the contraction groove. There are two pressing blocks above the locking buckle 102. The locking buckle 102 is pressed through the pressing blocks, so that the locking blocks of the sliding groove and the locking buckle 102 are no longer engaged, thus facilitating the reverse sliding of the locking buckle ​Driving gear 2, the driving gear 2 is installed on the outside of the twisting column of the twist switch, and when the driving gear 2 rotates, it will drive the twist switch to rotate. There are four driving gears 2 in total, and the four driving gears 2 are meshed with each other. Therefore, when the driving gear 2 on the left rotates, it will drive the other three driving gears 2 to rotate, so that the four twist switches are opened and closed synchronously. There is a connecting rod above the driving gear 2, and the connecting rod has three positioning grooves with a circular arc structure. The driving shaft 4 also has three positioning grooves with a circular arc structure. The connecting sleeve 501 is installed on the outside of the connecting rod of the driving gear 2 and the driving shaft 4. At this time, the connecting sleeve 501 connects the driving gear 2 and the driving shaft 4. There are three positioning blocks with a circular arc structure on the inner side of the connecting sleeve 501. Therefore, when the driving shaft 4 rotates, it will drive the driving gear 2 to rotate; the sealing cover 3, the sealing cover 3 has four mounting holes, and the sealing cover 3 is installed above the mounting shell 1; The drive shaft 4 is inserted into the mounting hole of the sealing cover 3, the mounting hole of the sealing cover 3 positions the drive shaft 4, the drive shaft 4 rotates in the mounting hole of the sealing cover 3, and the drive shaft 4 is installed with a clamp, which positions the bottom of the drive shaft 4; The connecting structure 5 is installed on the mounting shell 1. The connecting structure 5 is composed of a connecting sleeve 501, an extension rod 502 and a positioning rod 503. An annular groove is provided on the outer side of the connecting sleeve 501 to position the extension rod 502. There is a snap ring at the end of the extension rod 502, which is clamped in the annular groove of the connecting sleeve 501. Therefore, when the connecting sleeve 501 rotates, the extension rod 502 remains stationary. The connecting sleeve 501 is slidably connected to the outer side of the drive shaft 4. When the extension rod 502 moves up and down, the connecting sleeve 501 is driven to move. After the connecting sleeve 501 moves upward, the connecting sleeve 501 is no longer connected to the connecting rod of the drive gear 2. Therefore, when the drive shaft 4 rotates, the drive gear 2 will not be driven to rotate. It can be concluded that the rotation of the twist switch can be controlled by sliding the connecting sleeve 501, thereby performing individual control of the twist switch, which can be operated according to needs. To freely choose the rotation of the twist switch, the extension rod 502 is equipped with a rotatably connected positioning bolt, and the outer side of the sealing cover 3 is provided with four connecting blocks, and the bottom of the connecting block is provided with a threaded groove. When the extension rod 502 slides upward, the end of the positioning bolt is installed in the threaded groove of the connecting block to complete the position locking of the extension rod 502. There is a positioning rod 503 above the extension rod 502, and the positioning rod 503 is a cylindrical structure. A first supporting spring is sleeved on the outer side of the positioning rod 503, and the positioning rod 503 positions the first supporting spring. The first supporting spring elastically supports the extension rod 502 downward, so that the extension rod 502 is more stable after moving downward. The sealing cover 3 is provided with four sliding grooves of a U-shaped structure. The extension rod 502 is clamped in the sliding groove of the sealing cover 3, and the extension rod 502 slides in the sliding groove of the sealing cover 3. At the same time, the sliding groove also facilitates the installation and removal of the extension rod 502. The twisting seat 6 has a groove on the inner side of the twisting seat 6 that fits with the drive shaft 4. The twisting seat 6 is installed on the outer side of the drive shaft 4 through the groove. The twisting seat 6 is composed of two parts. The two-part twisting seat 6 facilitates the installation and disassembly of the sliding rod 7. The outer side of the twisting seat 6 has an external thread. A locking nut 601 is installed on the outer side of the twisting seat 6. The locking nut 601 locks the two-part twisting seat 6. When the twisting seat 6 is rotated, the drive shaft 4 is driven to rotate. The sliding rod 7 and the sealing cover 3 are provided with a positioning sleeve 301 above the sliding rod 7. The mounting holes of the positioning sleeve 301 and the sealing cover 3 are relatively aligned. The inner side of the positioning sleeve 301 has a locking groove distributed in a ring array. The end of the sliding rod 7 has an L-shaped pressing rod 701. The bottom of the pressing rod 701 has a locking block, which is clamped in the locking groove of the positioning sleeve 301. At this time, the locking groove of the positioning sleeve 301 locks the locking block, thereby concluding that the locking block will screw the seat 6 to lock it, avoiding To prevent the twisting seat 6 from rotating due to external factors and misoperation, a positioning groove with a stepped structure is provided on the inner side of the twisting seat 6, and the sliding rod 7 is installed in the positioning groove of the twisting seat 6. The sliding rod 7 is a stepped structure, and the positioning groove of the twisting seat 6 positions the sliding rod 7. The sliding rod 7 slides in the positioning groove of the twisting seat 6. A second supporting spring is sleeved on the outer side of the sliding rod 7. The second supporting spring elastically supports the sliding rod 7, so that the locking block of the pressing rod 701 is automatically clamped in the locking groove of the positioning sleeve 301.

[0021] In this embodiment, the driving gear 2 is first installed on the outside of the twisting column of the twist switch. When the driving gear 2 rotates, it drives the twist switch to rotate, so that the four driving gears 2 are meshed, and the connecting sleeve 501 is installed on the outside of the connecting column of the driving gear 2. At the same time, the extension rod 502 and the positioning rod 503 are installed. The sealing cover 3 is installed on the top of the mounting housing 1 by bolts, and the installation of the driving shaft 4 is completed at the same time. The twisting seat 6 is installed on the outside of the driving shaft 4, and the sliding rod 7 and the pressing rod 701 are installed at the same time. At this time, the locking block of the pressing rod 701 is clamped in the locking groove of the positioning sleeve 301. The locking groove of the positioning sleeve 301 locks the locking block, and the locking block locks the twisting seat 6, thereby preventing the twisting seat 6 from rotating due to external factors and misoperation. Install the power cord inside the terminal block 101, then turn the bolt to lock the power cord, and then push the locking buckle 102. The inclined block at the bottom of the locking buckle 102 presses the bolt to prevent the bolt from loosening. When the bolt is rotated in the opposite direction, the pressing block of the locking buckle 102 is pressed so that the locking blocks of the terminal block 101 and the locking buckle 102 are no longer engaged. Then, the locking buckle 102 is slid in the opposite direction, and the bolt can now be rotated in the opposite direction. The pressing rod 701 is pressed, and the twisting seat 6 is rotated to drive the driving shaft 4. When the driving shaft 4 rotates, the four driving gears 2 are rotated synchronously. Therefore, when the driving gear 2 on the left rotates, the other three driving gears 2 are rotated, so that the four twist switches are opened and closed synchronously. When the pressing rod 701 is stationary, the pressing rod 701 is automatically reset under the support of the second supporting spring, so that the locking block of the pressing rod 701 locks the twisting seat 6. When operating the switch individually, the extension rod 502 is slid upward and positioned by the bolt. At this time, the connecting sleeve 501 is no longer connected to the connecting rod of the drive gear 2. Therefore, when the drive shaft 4 rotates, the drive gear 2 will not be driven to rotate. It can be concluded that the rotation of the twist switch can be controlled by sliding the connecting sleeve 501, thereby individually controlling the twist switch, and the rotation of the twist switch can be freely selected according to needs.

[0022] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
