[0044] This application proposes a grounding device that facilitates quick connection, comprising: a main movable base 1, with a counterweight inside; a square edge 101 integrally formed on the outer bottom of the main movable base 1; a fixed outer ring 2 fixedly disposed in the middle of the outer side of the main movable base 1; a top plate frame 3, with a middle rod 301 fixedly disposed in the middle of the bottom of the top plate frame 3, the middle rod 301 being rotatably disposed in the middle of the main movable base 1; a set of connecting seats 4 fixedly disposed on the upper outer side of the main movable base 1; an inflation assembly 5 fixedly disposed on the outer side of the connecting seats 4; a take-up seat 6 fixedly disposed on the top of the top plate frame 3, the take-up seat 6 having an outer shell; the cross-section of the outer shell being U-shaped; a take-up wheel 601 rotatably disposed above the take-up seat 6 in conjunction with a bracket structure; a reset component for resetting is also disposed outside the shaft of the take-up wheel 601, the reset component being a spiral spring; a connecting wire 602 is wound around the outside of the take-up wheel 601, the connecting wire 602 being connected to the metal shaft of the take-up wheel 601; and a terminal 7 is connected to the outside of the connecting wire 602.

[0045] Specifically, the grounding device of this application is flexibly arranged through the main moving base 1, without the need to be placed on the ground or buried underground in advance; the winding wheel 601 provides the function of extending the use distance as needed. When grounding is required, the grounding device is moved to the predetermined position by the main moving base 1, and the contactor 7 is pulled out to connect to the electrical equipment, realizing the quick connection function. After the winding wheel 601 rotates, it keeps the electrical equipment and the connecting line 602 energized. The winding wheel can provide the functions of winding and unwinding, which can more conveniently extend the use distance. The connecting line is automatically retracted by the reset member, making it easy to operate.

[0046] The main movable seat 1 also includes: a pressing plate 102, a grounding copper sheet 103 fixedly installed at the bottom of the pressing plate 102, and a spring rod installed at the bottom of the square edge 101 at the top of the pressing plate 102, so that the pressing plate 102 can move up and down relative to the square edge 101; the intermediate rod 301 is electrically connected to the grounding copper sheet 103.

[0047] Specifically, the grounding copper sheet 103 at the bottom of the pressing plate 102 is in contact with the ground, and the intermediate rod 301 is electrically connected to the connecting wire, so as to realize the electrical connection between the grounding copper sheet 103, the intermediate rod 301, the connecting wire 602 and the terminal 7.

[0048] Among them, four sets of evenly distributed pneumatic telescopic rods 201 are fixedly connected to the bottom of the fixed outer ring 2. A movable outer shell 202 is fixedly installed at the bottom of the pneumatic telescopic rod 201. Four sets of universal wheels with bottoms lower than the movable outer shell 202 are fixedly installed on the outside of the movable outer shell 202, and the movable outer shell 202 is fitted outside the square edge 101.

[0049] Specifically, during grounding, the movable housing 202 is raised by the pneumatic telescopic rod 201, so that the grounding copper plate 103 contacts the ground. When the grounding equipment is moved without needing to be grounded, the movable housing 202 is lowered by the pneumatic telescopic rod 201, the casters contact the ground, and the main movable seat 1 is gradually supported, and the grounding copper plate 103 is separated from the ground.

[0050] The bottom of the top plate frame 3 is fixed with a set of limiting plates 302, and the top of the connecting seat 4 is set with a T-shaped structure and can contact the limiting plates 302.

[0051] Specifically, the intermediate rod 301 can rotate relative to the main moving seat 1, and the top plate frame 3 is connected to the intermediate rod 301, that is, the top plate frame 3 can rotate relative to the main moving seat 1 to meet the connection requirements in different directions. The T-shaped structure stops the limiting plate 302 to reduce the excessive rotation of the top plate frame 3.

[0052] The bottom of the connecting seat 4 is connected to a first one-way valve 401 and a second one-way valve 402 with opposite directions. The bottom of the second one-way valve 402 is connected to the fixed outer ring 2 by a pipe, and a vent valve 403 is also connected in the middle of the pipe.

[0053] Specifically, outside air passes through the first one-way valve 401 into the inflation assembly, then through the second one-way valve 402 into the fixed outer ring 2, which opens the air telescopic rod 201, brings the caster wheels to the ground, and supports the main moving seat 1.

[0054] The inflation component 5 includes an air pump; a limiting annular groove 501, which is provided on the outside of the telescopic end of the air pump; a protrusion 502, which is fixedly provided on the front end of the air pump; and a locking block 503, which can be fitted into the limiting annular groove 501. A first spring guide rod 504 is fixedly provided on the top of the locking block 503. A U-shaped cover 505 is provided on the first spring guide rod 504, which is fitted with a spring and passes through the protrusion 502. The bottom sides of the U-shaped cover 505 are designed to match the semi-circular groove on the top of the protrusion 502.

[0055] Specifically, the U-shaped cover 505 is moved along the protrusion 502 to adjust the position of the locking block 503. Since the locking block 503 is connected to the first spring guide rod 504, the locking block 503 can abut in the limiting ring groove 501, thereby stopping the end face of the air pump and limiting the position during the repeated compression of the air pump.

[0056] The take-up reel 601 has a locking tooth 603 on the outside of its left rotating shaft. The locking tooth 603 has a ratchet structure in the middle and a U-shaped groove on its outside. The take-up base 6 also includes a positioning card 604, which slides on the left side of the bracket of the take-up reel 601 via a second spring guide rod 605 at the bottom. The take-up frame 606 has a circular frame, and the right rotating shaft of the take-up reel 601 rotates within the circular frame of the take-up frame 606.

[0057] Specifically, based on the characteristics of the ratchet structure, it is easy to pull out the connecting wire and prevent the connecting wire from retracting, ensuring that the connecting wire 602 is properly extended outward. Then, the tension connector 7 can be used as a clamp to hold and fix it to the equipment node to complete the installation. Pulling down the second spring guide rod 605 and the positioning card 604 causes the positioning card 604 to disengage from the U-shaped groove of the positioning tooth 603, unlocking the positioning tooth 603. Then, the winding wheel 601 automatically resets through the worm spring, retracting the connecting wire 602.

[0058] The junction box 7 includes: a body; a flange 701, the body being cylindrical, with the flange 701 integrally formed on the outside of the body; a rear actuating lever 702, fixedly formed at the rear end of the body, with an auxiliary ring 703 fixedly formed at the top of the rear actuating lever 702; a merging cylinder 704, with two merging cylinders 704 rotatably formed on both sides of the front end of the body, and a wire-passing port provided at the front end of the merging cylinder 704; an internal frame 705, integrally formed inside the merging cylinder 704; and a copper clamping plate 706. The third spring guide rod 707 is elastically slidably connected to the built-in frame 705; the adjacent surfaces of the copper plates 706 on both sides are respectively provided with horizontal and vertical lines; the copper plates 706 are connected to the connecting line 602; the side connecting rod 708 is hinged to the rear side of the outer side of the merging cylinder 704; the sliding sleeve 709 has the rear end of the side connecting rod 708 hinged to both sides of the sliding sleeve 709, the bottom of the sliding sleeve 709 is fixedly provided with a front actuating rod 710, the sliding sleeve 709 slides outside the flange 701 of the connector 7, and a spring is provided inside the sliding sleeve 709.

[0059] Specifically, when grounding the equipment, directly hold the connector 7 and push the front lever 710 backward. The sliding sleeve 709, together with the side connecting rod 708, unfolds the two merging cylinders 704. Then, place the end of the ground wire in the middle of the two clamping copper plates 706. Then, release the sliding sleeve 709. The spring inside the sliding sleeve 709 will automatically reset, push the side connecting rod 708 back, close the two merging cylinders 704 to wrap the ground wire and complete the grounding.

[0060] like Figures 6 to 7As shown, there are two sets of merging cylinders 704. The two sets of merging cylinders 704 can form a cylindrical structure to protect the end of the grounding wire. Moreover, the merging cylinders 704 are controlled by a linkage structure. Pushing the front lever 710 backward causes the sliding sleeve 709 to cooperate with the side connecting rod 708 to unfold the two merging cylinders 704, so that the grounding wire can be connected. The tensioning connector 7 can also be directly used as a clamp to hold and fix it to the equipment node. Since the clamping copper sheet 706 is installed through the third spring guide rod 707, it has a buffering and adapting effect, which can ensure the stable fixing of the grounding wire.

[0061] The merging cylinder 704 is made of transparent material for easy observation.

[0062] The reset element is configured as a spiral spring to enable automatic retraction of the connecting wire.

[0063] Example 2:

[0064] Based on Example 1, such as Figures 8 to 9 As shown, the connecting line 602 can be extended. When needed, the connector 7 can be pulled outwards directly and fixed by the locking teeth 603 and the positioning card 604. The ratchet structure inside the locking teeth 603 rotates in one direction to ensure that the connecting line 602 is released outwards normally. When the second spring guide rod 605 and the positioning card 604 are pulled down, the positioning card 604 disengages from the U-shaped groove of the locking teeth 603, which will unlock the locking teeth 603. Then, the winding wheel 601 automatically resets through the worm spring, retracts the connecting line 602 and locks it in place.

[0065] Example 3:

[0066] Based on Example 1, such as Figure 3 As shown, when the movable housing 202 is raised, four sets of grounding copper plates 103 contact the ground. Based on the flatness of the ground and the counterweight of the main movable base 1, the grounding copper plates 103 can automatically adapt and maintain stable grounding. The number of grounding copper plates 103 and the number of take-up bases 6 are the same and correspond to each other, and the number can be increased as needed.

[0067] The specific usage and function of this embodiment are as follows: In this application, when in use, the main moving seat 1 is moved to a position that is easy to operate, and then the vent valve 403 is released. The air telescopic rod 201 automatically retracts through the internal spring to expel excess air. Then the moving outer shell 202 is raised so that the grounding copper plate 103 contacts the ground. According to the flatness of the ground and the counterweight of the main moving seat 1, the grounding copper plate 103 can automatically adapt and maintain stable grounding. Conversely, when it is necessary to raise the main moving seat 1, the vent valve 403 is closed, the U-shaped cover 505 is lifted and rotated 90 degrees. At this time, the U-shaped cover 505 is stuck outside the protrusion 502, and the locking block 503 is disengaged from the limiting ring groove 501. Then the air pump is repeatedly extended and retracted. Outside air enters the air pump through the first one-way valve 401, and then enters the fixed outer ring 2 through the second one-way valve 402, which opens the air telescopic rod 201, so that the caster wheel contacts the ground and the main moving seat 1 is lifted up.

[0068] When grounding the device, directly hold the connector 7 and push the front lever 710 backward. The sliding sleeve 709, together with the side connecting rod 708, unfolds the two merging cylinders 704. Then, place the end of the ground wire in the middle of the two clamping copper plates 706. Then, release the sliding sleeve 709. The spring inside the sliding sleeve 709 will automatically return to its original position, push the side connecting rod 708 back, close the two merging cylinders 704 to wrap the ground wire and complete the grounding.

[0069] When active connection to the equipment is required, in addition to the aforementioned control methods, it is also necessary to stretch the position of the connector 7, pull the connector 7 directly outward, and fix it with the locking tooth 603 and the positioning card 604. The ratchet structure inside the locking tooth 603 rotates in one direction to ensure that the connecting wire 602 is properly released outward. Then, the stretching connector 7 is used as a clamp to hold and fix it to the equipment node to complete the installation. Pull down the second spring guide rod 605 and the positioning card 604, the positioning card 604 disengages from the U-shaped groove of the locking tooth 603, unlocks the locking tooth 603, and then the winding wheel 601 automatically resets through the worm spring to retract the connecting wire 602.

[0070] The grounding device of this application, which facilitates quick connection, has the following advantages:

[0071] 1. This invention is equipped with a grounding device, which provides a function that can be selected according to the situation. The connection can be selected as needed. Push the front lever backward, and use the sliding sleeve and the side connecting rod to unfold the two merging cylinders. Then place the end of the ground wire in the middle of the copper plates on both sides. Release the sliding sleeve, and the spring inside the sliding sleeve will automatically reset. Push the side connecting rod back, close the two merging cylinders, wrap the ground wire, and complete the grounding. It can also actively connect the node, saving cumbersome wiring steps and protecting the wiring position.

[0072] 2. The winding wheel provides the function of extending the working distance as needed. The rotating frame ensures that the winding wheel remains powered after rotation, and the winding wheel provides winding and unwinding functions, which can more easily extend the working distance. In addition, the locking teeth and positioning clips can limit the position of the connecting wire. The ratchet structure can prevent the connecting wire from automatically retracting after being pulled out. When the positioning clip is released, the connecting wire will be automatically retracted by the worm spring, making operation convenient.

[0073] 3. The grounding copper plate provides a quick positioning and grounding connection structure. When the vent valve is released, the gas telescopic rod automatically retracts through the internal spring to expel excess air. Then, the moving shell automatically rises, allowing the grounding copper plate to contact the ground. The grounding copper plate automatically adapts to the flatness of the ground and the counterweight of the main moving base to maintain stable grounding. Different grounding copper plates are connected to different electrical contacts to avoid cross-current.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
