Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal handling tools, and in particular to a magnetic handling tool for handling thin sheets. Background Technology

[0002] Metal sheets are a common basic material in industrial processing. In actual production, the cutting, punching, and stamping of sheet metal are all done on the workbench. During the processing, manual loading, unloading and handling of sheet metal are required repeatedly.

[0003] In existing technologies, the handling of thin plates is mostly done by hand by workers, lacking specialized auxiliary handling tools. Due to the thinness of the plates themselves, when stacked, the surfaces of adjacent plates are tightly pressed together, and when placed on a workbench, the bottom surface of the plates is tightly pressed against the workbench surface, leaving insufficient space for fingers to reach in and grab. This makes it difficult for workers to quickly separate the thin plates from the stack or the workbench, resulting in inconvenient and inefficient handling operations. At the same time, manual handling also poses a risk of the thin plates' edges scratching the operators, creating certain operational hazards.

[0004] Therefore, a magnetic handling tool for handling thin plates is provided to address the above problems. Utility Model Content

[0005] This invention provides a magnetic handling tool for transporting thin plates to solve the technical problem of inconvenient gripping of thin plates.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions: This utility model provides a magnetic handling tool for transporting thin plates, including a handle; both ends of the handle are fixed with side tubes, and the bottom of the side tubes is fixed with a shell, and the bottom of the shell is open; a magnet is provided at the bottom of the shell, and the magnet is fixed to a pull rod by a connecting rod; the pull rod is located at the bottom of the handle and is slidably mounted on the side tubes vertically; a locking mechanism is provided inside the pull rod, and a locking sleeve for the locking mechanism to be inserted is fixed on the inner side wall of the side tube.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0017] The positive and progressive effects of this utility model are as follows: The aforementioned magnetic handling tool for transporting thin plates employs a magnetic attraction method to pick up the plates. The magnetic force of the magnet directly attracts and fixes the plates, easily lifting plates that are stacked or attached to a tabletop, effectively solving the problems of insufficient gripping space and difficulty in handling thin plates. Simultaneously, through the cooperative structure of the pull rod, connecting rod, magnet, and outer shell, unloading only requires pulling the pull rod upwards. This causes the connecting rod to lift the magnet vertically, while the bottom of the outer shell blocks the plate as it moves upwards with the magnet, allowing the magnet to continue moving inwards. This separation of the magnetic attraction between the magnet and the plate allows the plate to fall naturally under its own weight, completing the unloading process. The overall picking and unloading operation is simple and can effectively improve the efficiency of thin plate handling.

[0018] This handling tool is equipped with a locking mechanism that can lock the vertical position of the pull rod, connecting rod, and magnet during the handling of thin plates, preventing vertical movement of the pull rod, connecting rod, and magnet during handling and ensuring the stability of the magnetic handling state. Simultaneously, the operating push rod of this locking mechanism is located at the bottom of the pull rod. When the operator holds the pull rod with one hand, they can unlock the mechanism by pressing the push rod with their finger. Releasing the push rod automatically resets the locking mechanism. The unlocking and locking operations are convenient and require no additional personnel; a single person can independently complete all handling and unloading operations. Attached Figure Description

[0021] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments described herein.

[0022] like Figures 1-6 As shown, a magnetic handling tool for transporting thin plates includes a handle 1; both ends of the handle 1 are fixed with side cylinders 2, and the bottom of the side cylinders 2 is fixed with a housing 3, and the bottom of the housing 3 is provided with an opening.

[0023] A magnet block 4 is provided at the bottom of the outer casing 3, and the magnet block 4 is fixed to a pull rod 5 by a connecting rod 6.

[0024] The pull rod 5 is located at the bottom of the handle rod 1, and the pull rod 5 is slidably mounted on the side tube 2 in a vertical direction.

[0025] The pull rod 5 is provided with a locking mechanism 7, and the inner wall of the side tube 2 is fixed with a locking sleeve 9 for the locking mechanism 7 to be inserted.

[0026] The tool's initial state is as follows: Figures 2-3 As shown, the magnet 4 extends from the opening at the bottom of the outer casing 3. When handling the thin plate, the operator holds the handle 1 with one hand, moves the entire tool above the thin plate, and makes the magnet 4 adhere to the top surface of the thin plate. The magnet 4 attracts the thin plate. Then, the operator pulls the handle 1 upward, causing the thin plate and the entire tool to move downward together, leaving the stacked position of the thin plates. After the thin plate is transported to the workbench, the operator keeps the handle 1 in the pulled state with one hand, and unlocks the locking mechanism 7 with the other hand and pulls the lever 5 upward. The lever 5 drives the magnet 4 upward through the connecting rod 6. The thin plate on the magnet 4 moves together, and after the top surface of the thin plate adheres to the bottom surface of the outer casing 3, the thin plate is blocked and cannot continue to move with the magnet 4. The magnet 4 continues to move deeper into the outer casing 3, causing the magnet 4 to separate from the thin plate. The thin plate loses its magnetic attraction and falls onto the workbench by gravity, completing the unloading after handling. After unloading, release the lever 5. Under gravity, the lever 5, connecting rod 6, and magnet 4 fall back to their original positions. Figures 2-3 The state shown is then locked by the locking mechanism 7.

[0027] In practice, the magnet block 4 is a permanent magnet; the thin plate is made of iron or other magnetically attractive materials.

[0028] like Figures 1-2 As shown, a top cover 201 is fixed to the top port of the side cylinder 2, and a side through groove 202 is provided on one side of the side cylinder 2. The end of the pull rod 5 is slidably connected to the side through groove 202.

[0029] The top cover 201 is used to close the top port of the side tube 2, and the side through groove 202 is used for the pull rod 5 to pass through, so that the pull rod 5 extends into the side tube 2, thereby fixing the pull rod 5 to the connecting rod 6 set in the side tube 2; the side through groove 202 has a certain length in the vertical direction to ensure that the pull rod 5 can move vertically.

[0030] In such Figures 2-3 In the state shown, the bottom surface of the pull rod 5 is in contact with the bottom wall of the side through groove 202, providing a stop and support for the pull rod 5 to descend to the low position.

[0031] like Figures 2-3 As shown, the top of the outer shell 3 is provided with a guide hole 302, and the guide hole 302 is connected to the bottom port of the side cylinder 2. The connecting rod 6 is disposed inside the side cylinder 2, and the connecting rod 6 is slidably engaged with the guide hole 302.

[0032] The guide hole 302 provides vertical guidance for the vertical movement of the connecting rod 6, thereby providing vertical guidance for the overall structure consisting of the pull rod 5, the magnet block 4, and the connecting rod 6.

[0033] like Figure 2 As shown, a flexible ring 301 is fixed on the bottom open edge of the outer casing 3. The flexible ring 301 is preferably made of silicone or rubber. When the pull rod 5 is pulled upward, the magnet block 4 drives the thin plate to move upward, and the thin plate makes contact with the flexible ring 301, providing soft contact for the thin plate and avoiding damage to the thin plate during unloading.

[0034] like Figures 4-6 As shown, the pull rod 5 has a hollow shell structure; the locking mechanism 7 includes a trapezoidal block 705 disposed at the center of the pull rod 5, the trapezoidal block 705 is connected to a lifting part, and two sets of movable locking rods 701 are symmetrically arranged on both sides of the trapezoidal block 705. The movable locking rods 701 are used to insert into or leave the locking sleeve 9. The end of the movable locking rod 701 is connected to the side wall of the trapezoidal block 705 through a sliding part. The movable locking rod 701 is slidably sleeved with the guide sleeve 702 fixed inside the pull rod 5, and the movable locking rod 701 extends out of the end of the pull rod 5; an elastic connection part is provided between the movable locking rod 701 and the guide sleeve 702.

[0035] In such Figures 2-3 In the indicated state, the movable locking rod 701 of the locking mechanism 7 is inserted into the locking sleeve 9, providing a lock for the pull rod 5, connecting rod 6, and magnet 4. After the magnet 4 magnetically attracts the thin plate, the pull rod 5, connecting rod 6, and magnet 4 will not wobble up and down around the entire tool during handling, ensuring stability during handling. Before unloading the thin plate, the movable locking rod 701 is disengaged from the locking sleeve 9 to complete the unlocking.

[0036] The trapezoidal block 705 is an inverted isosceles trapezoidal structure, and the width of the bottom of the trapezoidal block 705 is smaller than the width of the top of the trapezoidal block 705.

[0037] By setting the trapezoidal block 705 as described above, the state of contact between the top sidewall of the trapezoidal block 705 and the sliding part at the end of the movable locking rod 701 is switched to the state of contact between the bottom sidewall and the sliding part at the end of the movable locking rod 701. The two movable locking rods 701 move closer to each other, that is, the movable locking block moves inward into the pull rod 5, so that the movable locking rod 701 leaves the lock sleeve 9; conversely, the movable locking rod 701 moves outward from the pull rod 5.

[0038] The lifting part includes a guide post 707 and a push rod 8 fixed to the bottom of the trapezoidal block 705; the guide post 707 is slidably engaged with a groove 7052 opened at the top of the trapezoidal block 705, a second spring 708 is sleeved on the guide post 707, and the top of the trapezoidal block 705 is elastically connected to the inner wall of the top of the pull rod 5 through the second spring 708; the push rod 8 passes through a hole opened at the bottom of the pull rod 5.

[0039] By pushing the push rod 8 upward, the trapezoidal block 705 can be moved upward and the second spring 708 can be compressed. After releasing the push rod 8, the trapezoidal block 705 can be lowered by its own weight and the elastic force of the second spring 708. During the lifting and lowering movement of the trapezoidal block 705, the guide post 707 and the groove 7052 provide sliding guidance.

[0040] like Figure 5 As shown, a baffle is provided at the bottom of the push rod 8, and a silicone pad is provided on the bottom surface of the baffle.

[0041] In practice, when the trapezoidal block 705 rises to its highest position, the baffle plate is in contact with the bottom surface of the pull rod 5 to prevent it from reaching its final position; when the trapezoidal block 705 descends to its lowest position, the bottom surface of the trapezoidal block 705 is in contact with the bottom inner wall of the pull rod 5 to prevent it from reaching its final position.

[0042] The silicone pad provides soft contact for the hand when the push rod 8 is pushed.

[0043] The sliding part includes a roller 706 rotatably mounted on the end of the movable locking rod 701; an annular guide groove 7061 is provided on the cylindrical surface of the roller 706, and a guide strip 7051 is fixed on the side wall of the trapezoidal block 705, and the guide groove 7061 and the guide strip 7051 are slidably connected.

[0044] When the trapezoidal block 705 moves up and down, the roller 706 provides rolling friction to reduce frictional resistance, while the guide bar 7051 and guide groove 7061 provide guidance.

[0045] The elastic connection includes a first spring 703 sleeved on the movable locking rod 701. The guide sleeve 702 is elastically connected to a fixed plate 704 via the first spring 703, and the fixed plate 704 is fixedly sleeved on the movable locking rod 701. The elastic connection between the movable locking rod 701 and the guide sleeve 702 is achieved through the elastic connection.

[0046] The working process of the locking mechanism 7 is as follows: After the thin plate is transported and before unloading, one hand holds the pull rod 5 while the fingers press and push the push rod 8, causing the trapezoidal block 705 to move upward and compress the second spring 708. The elastic force of the first spring 703 keeps the roller 706 in contact with the side wall of the trapezoidal block 705. The roller 706 moves to the bottom side of the trapezoidal block 705, and the movable locking rod 701 moves into the pull rod 5 through the guide sleeve 702. The movable locking rod 701 leaves the locking sleeve 9, completing the unlocking.

[0047] After the thin plate is unloaded, the pull rod 5 is lowered to fit against the bottom surface of the side through groove 202, so that the movable locking rod 701 is aligned with the locking sleeve 9. Then the push rod 8 is released, and the trapezoidal block 705 moves downward by the elastic force of the second spring 708 and the gravity of the trapezoidal block 705. The roller 706 is pushed by the trapezoidal block 705, so that the movable locking rod 701 is inserted into the locking sleeve 9 and the first spring 703 is compressed and deformed.

[0048] The locking mechanism 7 described above is easy to lock and unlock. The locking mechanism 7 can be operated simultaneously with one hand pulling the lever 5 without the need for assistance from other personnel.

[0049] This utility model is not limited to the above-described embodiments. Any changes made to its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
