Description

Technical Field

[0001] The utility model relates to the technical field of charging pile maintenance, in particular to a charging pile maintenance tool. Background Art

[0002] The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time, cost data printing and other operations. The charging pile display screen can display data such as charging amount, cost, and charging time.

[0003] The utility model patent with publication number CN216991682U discloses a charging pile maintenance tool, including: a tool body, which is hollow, a screwdriver is detachably mounted on one end of the tool body, a screw collection groove is fixedly mounted on the side of the tool body near the screwdriver end, and a magnet ring is fixedly connected to the middle of the screw collection groove. When repairing, put the removed screws into the screw collection groove, and the magnet ring in the screw collection groove will absorb the screws to prevent them from being lost.

[0004] The above tools have the following problems: Most screwdriver heads are made of magnetic materials and are magnetic, so they can attract iron screws. When unscrewing the screws of the charging pile for repair, the screwdriver head absorbs the screws, but the absorption force is not strong, and the screws are easily dropped when encountering collisions. Collisions are more likely to occur in narrow places, and it is difficult to remove the dropped screws, affecting the repair process. In addition, iron screws are prone to rust, so stainless steel screws are used instead of iron screws on many devices. Stainless steel screws are not magnetic, and the screwdriver heads of the above tools cannot be absorbed, which makes it easier for the stainless steel screws to fall during operation, making it inconvenient to use. Utility Model Content

[0005] The purpose of the utility model is to provide a charging pile maintenance tool to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A charging pile maintenance tool comprises: a handle, one end of which is detachably connected to a screwdriver, and also comprises: a fixing ring, which is detachably connected to one end of the handle close to the screwdriver, a limiting column is fixed on the side of the fixing ring away from the handle, and a limiting plate is fixed on the end of the limiting column; a moving ring is arranged on the side of the fixing ring away from the handle, a first slide groove is arranged on the side of the moving ring close to the handle, a second slide groove is arranged on the inner side of the moving ring, the limiting plate is located inside the first slide groove, an induction switch is arranged in the first slide groove close to the handle, a first spring is arranged between the fixing ring and the moving ring, and a button battery is arranged in the moving ring; a moving rod is arranged in the second slide groove, the moving rod is slidably connected to the moving ring, one end of the moving rod extends out of the second slide groove, a second spring is arranged between the moving rod and the moving ring, and a resistance component is fixed on one end of the moving rod extending out of the second slide groove; an iron sheet is located in the second slide groove, the iron sheet is fixed on the outer periphery of the moving rod, and an electromagnet is arranged in the second slide groove close to the resistance component. Use the screwdriver head to tighten the screw. During the process, the first spring pushes the moving ring to fit the working surface, so that the screwed out screw is located on the inner circumference of the moving ring. After tightening is completed, move the handle in the direction of screwing out the screw. The moving ring always fits the working surface under the action of the first spring until the limit piece contacts the sensing switch, and the sensing switch connects the electromagnet and the button battery. After the electromagnet is energized, it attracts the iron sheet to move the moving rod, and the resistance assembly resists the screw to clamp the screw to prevent it from falling off. Then remove the screw and save it, which effectively prevents the screwed out screw from falling into the charging pile during maintenance, affecting the maintenance process.

[0008] Optionally, the resistance component includes a fixed plate, which is fixed to one end of the moving rod extending out of the second sliding groove. The fixed plate is elastically connected to the moving plate on the side away from the second sliding groove. The fixed plate and the moving plate can be connected by a spring. After the moving plate resists the screw, the spring can both push the moving plate to clamp the screw and play a buffering role.

[0009] Optionally, the cross section of the movable plate is an arc shape, which better fits the outer circumference of the screw and clamps the screw more reliably.

[0010] Optionally, a friction strip is provided on the side of the movable plate away from the second slide groove, and the friction strip is provided to further prevent the screw from detaching from the movable plate when encountering a collision, thereby making the tool more reliable.

[0011] Optionally, the outer circumference of the fixed ring is rotatably connected to a limit hook, and a clamping column is fixed on the outer circumference of the movable ring, and the limit hook is clamped with the clamping column. This prevents the electromagnet from being energized when the tool is not in use. When the tool is used, the movable ring is moved to rotate the limit hook and separate it from the clamping column.

[0012] Optionally, the limit hook is made of iron, and an annular magnet is provided on the outer periphery of the fixed ring. When the tool is in use, it needs to be frequently moved and rotated. The limit hook is adsorbed by the annular magnet to prevent the limit hook from shaking and affecting the work.

[0013] Optionally, a lighting lamp is fixed to one end of the movable ring away from the grip, and a switch of the lighting lamp is arranged on the outer periphery of the movable ring, so that the screwdriver can be more easily inserted into the corresponding position on the screw when insufficient light is provided.

[0014] Optionally, the lighting lamp has a ring-shaped structure, which can more comprehensively illuminate the screws that need to be tightened, making it more convenient to use.

[0015] Optionally, a ring-shaped protrusion is provided on one side of the handle close to the fixing ring, and threads are provided on both the inner and outer sides of the protrusion. The screwdriver is screwed to the inner periphery of the protrusion, and the fixing ring is screwed to the outer periphery of the protrusion. The fixing ring is screwed to the protrusion, and the fixing ring can be removed at any time, that is, when the screw does not need to be clamped, the fixing ring can be removed from the handle, and the fixing ring can be reattached when it is needed, which has a wider range of applications.

[0016] Optionally, a friction pad is provided on the periphery of the handle, and inclined stripes are provided on the periphery of the friction pad, and a hanging ring is fixed on the end of the handle away from the fixing ring. The friction pad and the inclined stripes can prevent the hand from slipping when the handle is rotated, and the hanging ring can make the tool easy to hang and use.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] In the utility model, the handle is held and turned, and the screw is tightened by the screwdriver head. During the process, the first spring pushes the moving ring to fit the working surface, so that the screwed-out screw is located on the inner periphery of the moving ring. After the screwing is completed, the handle is moved along the screwing-out direction of the screw. The moving ring is always in contact with the working surface under the action of the first spring, and waits until the limit plate contacts the sensing switch, and the sensing switch connects the electromagnet and the button battery. After the electromagnet is energized, the iron plate is attracted to move the moving rod, and the abutment assembly abuts the screw, clamps the screw, and prevents the screw from falling off. After that, the screw can be removed and stored, which effectively prevents the screwed-out screw from falling into the charging pile when the charging pile is repaired, thereby affecting the repair process.
