[0017] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0018] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0019] Reference Figures 1-10This embodiment provides a push-lock low-voltage branch switch quick grounding device, including a mounting part 1, on which a connecting part 2 is provided; the connecting part 2 is provided to fix the grounding wire and the connecting block 211 together, and the mounting part 1 is provided to install the connecting block 211 on the connector 114, so as to realize the quick installation of the grounding wire.

[0020] Furthermore, the mounting part 1 includes a base 11, a fixing member 12 disposed on the base 11, a pressing member 13 disposed on the fixing member 12, and a sliding member 14 disposed on the pressing member 13; The base component 11 is a low-voltage branch switch and its accessories, which is used to facilitate the installation of the fixing component 12. The fixing component 12 is set to install the connecting block 211 on the base component 11, thereby completing the installation of the grounding wire. The pressing component 13 is set to restrict the fixing component 12, thereby fixing the fixing component 12. The sliding component 14 is set to provide moving space for the pressing component 13, so that the pressing component 13 moves according to the trajectory of the sliding component 14 when it moves.

[0021] Preferably, the grounding wire is connected to the base member 11 by the fixing member 12, and then the sliding member 14 provides the movement trajectory of the pressing member 13, so that the pressing member 13 presses the fixing member 12 inward, thereby fixing the fixing member 12 to the base member 11.

[0022] In summary: The grounding wire is fixed to the connecting block 211 by the connecting part 2, and then the grounding wire is sleeved on the base component 11 composed of the low-voltage shunt switch and its accessories in the mounting part 1 by the fixing part 12. Then, the sliding part 14 provides a preset moving trajectory for the pressing part 13, so that the pressing part 13 presses the fixing part 12 inward along the trajectory, thereby making the fixing part 12 stably assembled on the base component 11. Finally, the connecting block 211 is installed on the connector 114 by the mounting part 1, so as to realize the rapid installation of the grounding wire.

[0023] Reference Figures 1 to 7 As an optional embodiment, a push-lock low-voltage branch switch quick grounding device is provided, including a base component 11 including a low-voltage branch switch body 111, a connecting conductor 112 disposed on the low-voltage branch switch body 111, a fixing bolt 113 disposed on the connecting conductor 112, and a connector 114 fixedly connected to the fixing bolt 113.

[0024] The low-voltage branch switch body 111 controls the on / off state of the low-voltage branch; the connecting conductor 112 is used to achieve a reliable connection between the grounding wire and the low-voltage branch switch body 111; the fixing bolt 113 is fixed on the lower side of the connecting conductor 112, and its function is to provide a stable installation base for the connector 114; the connector 114 achieves rapid installation of the grounding wire through connection with the fixing member 12.

[0025] Furthermore, the fastener 12 includes a limiting groove 121 formed on the connector 114, a sleeve ring 122 sleeved on the outer wall of the connector 114, a hole 123 formed on the sleeve ring 122, and a limiting bead 124 disposed inside the hole 123.

[0026] The limiting groove 121 is used to cooperate with the limiting bead 124 to fix the sleeve ring 122; the sleeve ring 122 is sleeved on the connector 114 to realize the effective connection between the connector block 211 and the mounting head; the hole 123 is used to place the limiting bead 124 so that the limiting bead 124 can extend into the limiting groove 121, and finally complete the fixing of the sleeve ring 122.

[0027] Preferably, after the sleeve ring 122 is fitted onto the connector 114, the limiting bead 124 in its hole 123 will fall into the limiting groove 121, thereby achieving the connection and fixation between the sleeve ring 122 and the connector 114.

[0028] Furthermore, the slider 14 includes a shelf 141, a groove 142 formed on the shelf 141, and a slider 143 connected inside the groove 142.

[0029] The shelf 141 has a groove 142 for the slider 143 to slide inside. Through the cooperation and linkage of multiple grooves 142 and slider 143, the extrusion block 131 in the extrusion member 13 is driven to expand and contract, thereby completing the fixing and unlocking operation of the limit bead.

[0030] Furthermore, the extrusion member 13 includes an extrusion block 131 fixedly connected to the slider 143, a cavity 132 opened on the extrusion block 131, and an annular spring 133 disposed inside the cavity 132.

[0031] The extrusion block 131 is fixedly connected to the slider 143 and can move along the track of the slide groove 142 with the slider 143. The cavity 132 in the middle of the extrusion block 131 contains a ring spring 133. With the help of the elastic force of the ring spring 133, the extrusion block 131 moves towards the middle and extrudes the limiting bead 124, so that the limiting bead 124 is embedded in the limiting groove to fix the sleeve ring 122, and finally achieves a stable connection between the connecting block 211 and the outside of the connecting head 114.

[0032] Preferably, the grounding wire installation process can be started by fitting the sleeve ring 122 onto the outer wall of the connector 114. During this process, the limiting bead in the hole 123 in the middle of the sleeve ring 122 is embedded in the limiting groove. At the same time, the elastic force of the ring spring 133 drives multiple sets of pressing blocks 131 to move towards the center along the slide groove 142 and generate compression, so that the limiting bead is firmly embedded in the limiting groove to complete the installation and fixation of the sleeve ring 122, and finally realizes the rapid connection between the connector block 211 and the connector 114.

[0033] In summary: by fitting the sleeve 122 of the fixing member 12 onto the outer wall of the connector 114, the limiting bead 124 in the hole 123 of the sleeve 122 will initially fall into the limiting groove 121 of the connector 114; at the same time, the sliding groove 142 on the shelf 141 of the sliding member 14 and the slider 143 form a linkage, the pressing block 131 of the pressing member 13 is fixedly connected to the slider 143 and can move along the sliding groove 142 with the slider 143, the annular spring 133 built into the cavity 132 in the middle of the pressing block 131 drives multiple sets of pressing blocks 131 to move towards the middle by elastic force, thereby pressing the limiting bead 124 to make it firmly embedded in the limiting groove 121, realizing the reliable fixing of the sleeve 122 and the connector 114, and finally achieving a quick and stable connection between the connecting block 211 and the connector 114 through the cooperation of the connector 114 and the fixing member 12, thus completing the installation of the grounding wire.

[0034] Reference Figure 1 , Figures 4 to 10 As an optional embodiment, a push-lock low-voltage branch switch quick grounding device is provided, including a connecting part 2 including a connecting member 21, including a connecting block 211 fixedly connected to the outside of the shelf 141, a connecting rod 212 disposed on the connecting block 211, a connecting ring 213 disposed on the connecting rod 212, and a grounding wire body 214 fixedly connected to the connecting ring 213.

[0035] The connecting block 211 is used to connect the grounding wire body 214 and the connector 114 to form a conductive loop so that the voltage can be conducted to the ground through the grounding wire; the connecting rod 212 is used to install the connecting ring 213 so that the connecting ring 213 is fixed on the connecting block 211; the connecting ring 213 is used to fix the grounding wire body 214, thereby realizing the quick connection between the grounding wire body 214 and the connecting block 211.

[0036] Preferably, by installing a connecting ring 213 on the grounding wire body 214, the installation of the grounding wire and the connector 114 can be completed simply by fitting the connecting ring 213 onto the connecting rod 212. Then, the grounding wire can be installed and fixed by quickly installing and removing the mounting part 1.

[0037] Furthermore, the connecting part 2 also includes a limiting member 22, which includes a storage groove 221 opened on the connecting rod 212, a storage tube 222 fixedly connected to the inner wall of the storage groove 221, a limiting block 223 slidably connected to both ends of the storage tube 222, and a limiting spring 224 disposed in the middle of the limiting block 223.

[0038] The storage slot 221 is located in the middle of the connecting rod 212 and is used to place the storage tube 222 and the limiting block 223. The storage tube 222 is used to install the two limiting blocks 223 and the limiting spring 224 between them. The function of the limiting spring 224 is to push the two limiting blocks 223 to reset after they are squeezed.

[0039] Preferably, the outer side of the limiting block 223 is chamfered and both ends are arc-shaped, so that it can retract into the storage groove 221 in the middle of the connecting rod 212 after being squeezed; when installing the connecting ring 213, it is sleeved on the connecting rod 212 and pushed towards the connecting block 211. The inner wall of the connecting ring 213 squeezes the two limiting blocks 223 to retract into the storage groove 221. After the connecting ring 213 passes the limiting block 223, the limiting spring 224 pushes the limiting block 223 to reset, thereby realizing the limiting and fixing of the connecting ring 213, so that it cannot fall off without the action of external force.

[0040] Furthermore, the connecting part 2 also includes a splicing component 23, which includes a groove 231 formed on the connecting rod 212, a splicing groove 232 formed on the connecting rod 212, a long rod 233 disposed inside the groove 231, and a limiting block 234 fixedly connected to the outer wall of the long rod 233.

[0041] The groove 231 is used to allow the long rod 233 to extend into the connecting rod 212, while the splicing groove 232 works with the limiting block 223 to lock the long rod 233, thereby achieving a stable connection between the connecting rod 212 and the long rod 233.

[0042] Preferably, when installing the long rod 233, first insert the long rod 233 into the groove 231, and align the limiting block 223 with the splicing groove 232 on the connecting rod 212; then push the long rod 233 inward so that the limiting block 223 enters the splicing groove 232, and then rotate the long rod 233 clockwise to drive the limiting block 223 to rotate synchronously; after releasing the long rod 233, the reset button pushes the long rod 233 outward so that the limiting block 223 is engaged with the splicing groove 232, and finally the connection between the long rod 233 and the connecting rod 212 is completed; disassembly can be completed by reversing the operation.

[0043] Furthermore, the connecting part 2 also includes a reset member 24, which includes a positioning rod 241 fixedly connected to the end of the long rod 233, a washer 242 slidably connected to the positioning rod 241, and a reset spring 243 fixedly connected to the washer 242.

[0044] The positioning rod 241 is used to install the shim 242 and the return spring 243. The shim 242 is used to cooperate with the return spring 243 to push the long rod 233 outward, thereby locking the long rod 233.

[0045] Furthermore, an insulated handle 3 is fixedly connected to the other end of the long rod 233.

[0046] In summary: The grounding wire body 214 and the connector 114 are connected by the connecting block 211 of the connector 21 to form a conductive circuit. The connecting rod 212 provides an installation base for the connecting ring 213. The connecting ring 213 fixes the grounding wire body 214. During installation, the connecting ring 213 is directly sleeved onto the connecting rod 212 to start the assembly. During the sleeve process, the inner wall of the connecting ring 213 presses against the chamfered and arc-shaped limiting block 223 in the limiting member 22, causing it to retract into the receiving tube 222 in the storage groove 221 in the middle of the connecting rod 212. After the connecting ring 213 passes the limiting block 223, the limiting spring 224 in the middle of the limiting block 223 pushes the limiting block 223 to reset, thus realizing the connection of the connecting ring 213. The limiting and fixing mechanism prevents detachment; simultaneously, the splicing component 23 inserts the long rod 233 with the insulated handle 3 into the groove 231 of the connecting rod 212, so that the limiting block 234 on the outer wall of the long rod 233 is aligned with the splicing groove 232 and pushed inward and rotated clockwise. The reset spring 243 on the positioning rod 241 of the reset component 24 pushes the long rod 233 outward with the help of the washer 242, so that the limiting block 234 is engaged in the splicing groove 232 to complete the stable connection between the long rod 233 and the connecting rod 212. The reverse operation can be used to unlock it when disassembling. All components work together to achieve quick installation, stable fixing and convenient disassembly of the grounding wire body 214 and the connector 114, ensuring that the voltage is reliably conducted to the ground through the grounding wire.

[0047] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
