Description

Technical Field

[0001] This utility model relates to the field of strong magnet handling technology, and in particular to a clamp for strong magnets. Background Technology

[0002] With the rapid development of modern technology, strong magnets, due to their excellent magnetic properties, are widely used in fields such as new energy vehicle motors, high-precision medical magnetic resonance imaging equipment, and aerospace precision instruments. As application scenarios expand, the requirements for the magnetic field strength of strong magnets are constantly increasing, and product specifications are showing a trend of diversification. The demand for small strong magnets (such as single strong magnets with a side length or diameter of less than 5 cm and a weight of less than 100 grams) is becoming increasingly significant.

[0003] In existing technologies, specialized tools are typically used to handle and move large single strong magnets. However, these tools are generally bulky and unsuitable for the delicate handling of small, single strong magnets. Therefore, in actual production, packaging, and installation processes, the movement of small, single strong magnets is usually done manually. Because strong magnets possess high-intensity magnetic fields, they are prone to attracting other magnets or ferromagnetic objects during handling. The instantaneous, powerful squeezing and impact forces can easily cause finger injuries, crushing injuries, and other safety hazards.

[0004] Therefore, it is necessary to develop a clamp for single small strong magnets to address the above-mentioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a clamp for strong magnets, in order to solve the problem that the use of manual handling of single small strong magnets in the prior art can easily lead to safety accidents.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model relates to a clamp for strong magnets, which is made of a non-ferromagnetic material;

[0008] Includes a connecting component, one end of which is hinged to two sets of connecting rod assemblies;

[0009] One end of the connecting rod assembly is provided with a clamping component for clamping a small strong magnet.

[0010] A pressing component is provided at the other end of the connecting component;

[0011] The pressing component is provided with a driving component, which is slidably connected to the connecting component and is also drively connected to the linkage assembly.

[0012] Optionally, the linkage assembly includes a first rod hinged to the connecting component, a second rod hinged to the connecting component, and a third rod with its two ends hinged to the first rod and the second rod respectively. The axial distance between the hinge holes at both ends of the first rod is equal to the axial distance between the hinge holes at both ends of the second rod, and the first rod and the second rod are arranged parallel to each other.

[0013] Optionally, the clamping assembly includes a fourth rod with one end fixedly connected to the third rod, and a fixing block is fixed to the end of the fourth rod away from the third rod.

[0014] Optionally, a buffer layer is fixed to one side of the fixing block.

[0015] Optionally, the pressing assembly includes a fifth rod and a compression spring, one end of which is fixedly connected to the fifth rod, and the other end of which is fixedly connected to the connecting component.

[0016] Optionally, the drive assembly includes a sixth rod with one end fixedly connected to the fifth rod. A connecting plate is fixed on the first rod. One side of the connecting plate is configured as an arc surface, and a plurality of first teeth are provided on the arc surface. A plurality of second teeth for meshing with the first teeth are provided on the end of the sixth rod away from the fifth rod. A guide block is fixed on the connecting component, and the sixth rod slides through the guide block.

[0017] Optionally, a limiting component is provided on the sixth rod, and the limiting component abuts against the side of the guide block away from the fifth rod.

[0019] Optionally, the through grooves are spaced apart along the length of the connecting component; the length of the through grooves is between 5 cm and 10 cm, and the width of the through grooves is between 3 cm and 5 cm.

[0020] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0021] The operating structure, consisting of a pressing component, a driving component, a linkage component, and connecting parts, eliminates the need for operators to directly contact small, strong magnets. This effectively avoids the strong squeezing and impact forces generated by magnets attracting each other or attracting ferromagnetic objects during manual handling, which could cause finger pinching or crushing injuries.

[0022] The push-button drive design, combined with the through-slot structure, makes the operation simple and smooth. The operator only needs to place their fingers in the through-slot and press the fifth lever with their palm to quickly open and close the clamps. Attached Figure Description

Detailed Implementation

[0028] The core of this invention is to provide a clamp for strong magnets, which solves the problem that the use of manual handling of single small strong magnets in the prior art can easily lead to safety accidents.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In one specific embodiment of this utility model, the clamp is made of a non-ferromagnetic material, such as copper, aluminum alloy, plastic, ceramic, etc.

[0032] This clamp includes a connecting part 100, one end of which is hinged to two sets of connecting rod assemblies;

[0033] One end of the connecting rod assembly is equipped with a clamping component for holding a small strong magnet; the small strong magnet can be a single strong magnet with a side length or diameter of less than 5 cm and a weight of less than 100 grams.

[0034] A pressing component is provided at the other end of the connecting part 100;

[0035] The pressing component is equipped with a driving component, which is slidably connected to the connecting part 100 and is also drively connected to the linkage assembly.

[0036] In a specific embodiment of this utility model, the linkage assembly includes a first rod 200 hinged to the connecting component 100, a second rod 300 hinged to the connecting component 100, and a third rod 400 with both ends hinged to the first rod 200 and the second rod 300 respectively. The axial distance between the hinge holes at both ends of the first rod 200 is equal to the axial distance between the hinge holes at both ends of the second rod 300. The first rod 200 and the second rod 300 are arranged parallel to each other, that is, the first rod 200, the second rod 300, the third rod 400, and the connecting component 100 form a parallelogram structure. This parallelogram linkage structure has good stability and transmission performance. Under the action of the driving component, it can ensure that the clamping component opens and closes smoothly, realizing reliable clamping and release of small strong magnets.

[0037] In a specific embodiment of this utility model, the clamping assembly includes a fourth rod 500, one end of which is integrally formed or welded to the third rod 400, and a fixing block 600 is fixed (e.g., welded) to the end of the fourth rod 500 away from the third rod 400.

[0038] In one specific embodiment of this utility model, a buffer layer 700 is fixed to one side of the fixing block 600. The buffer layer 700 may be, but is not limited to, a rubber pad. The side of the rubber pad away from the fixing block 600 is provided with anti-slip texture. The rubber pad may be bolted or glued to the fixing block 600. The buffer layer 700 can provide a cushioning effect when clamping a strong magnet, avoiding damage to the magnet surface due to excessive clamping force; the anti-slip texture can increase the friction with the magnet surface, preventing the magnet from slipping during transportation.

[0039] In a specific embodiment of this utility model, the pressing component includes a fifth rod 800 and a compression spring 900. One end of the compression spring 900 is fixedly connected to the fifth rod 800 (e.g., by welding), and the other end of the compression spring 900 is fixedly connected to a connecting component 100 (specifically, the connecting component 100 may be a plate structure, with a support plate 101 welded to one side of the plate structure, and the support plate 101 is welded and fixedly connected to the compression spring 900). By pressing the fifth rod 800, the compression spring 900 is compressed, providing power to the driving component; when the fifth rod 800 is released, the compression spring 900 returns to its original state, allowing the clamp to return to its initial state for the next clamping operation.

[0040] In a specific embodiment of this utility model, the driving assembly includes a sixth rod 1000 whose one end is fixedly connected (e.g., welded) to the fifth rod 800. A connecting plate 210 is fixed (e.g., welded) on the first rod 200. One side of the connecting plate 210 is configured as an arc-shaped surface, and a plurality of first teeth are provided on the arc-shaped surface. A plurality of second teeth for meshing with the first teeth are provided at the end of the sixth rod 1000 away from the fifth rod 800. A guide block 110 is fixed (e.g., welded) on the connecting component 100, and the sixth rod 1000 slides through the guide block 110. When the fifth rod 800 is pressed, the sixth rod 1000 slides along the length of the connecting component 100 under the guidance of the guide block 110. Through the meshing transmission of the second tooth and the first tooth, the linear motion of the sixth rod 1000 is converted into the swing of the first rod 200, the second rod 300 and the third rod 400. Then, the third rod 400 drives the fourth rod 500 and the fixing block 600 to swing, so that the two fixing blocks 600 move closer to each other, thereby clamping the small strong magnet.

[0041] In a specific embodiment of this utility model, a limiting component 1100 is provided on the sixth rod 1000, and the limiting component 1100 abuts against the side of the guide block 110 away from the fifth rod 800. The limiting component 1100 prevents the second tooth on the sixth rod 1000 from separating from the first tooth on the connecting plate 210. The limiting component 1100 can be a bolt threadedly connected to the sixth rod 1000.

[0042] In a specific embodiment of this utility model, the connecting component 100 is provided with a plurality of through slots 120.

[0043] In a specific embodiment of this utility model, through slots 120 are spaced apart along the length of the connecting component 100; the length of the through slots 120 is between 5 cm and 10 cm, and the width of the through slots 120 is between 3 cm and 5 cm. Specifically, the connecting component 100 can adopt a plate structure. The through slots 120 can reduce the overall weight of the clamp, making it easier for operators to use for extended periods; on the other hand, they allow the operator's fingers to enter and exit. When in use, a finger can enter any through slot 120, and the palm can press down on the fifth rod 800, making the operation process comfortable and convenient.

[0044] The following is the usage process of a clamp for strong magnets according to this utility model: When using this clamp to grip a small strong magnet, the operator places their fingers into the through groove 120 of the connecting component 100 and presses the fifth rod 800 with their palm. At this time, the compression spring 900 is compressed. Under the guidance of the guide block 110, the fifth rod 800 drives the sixth rod 1000 to slide along the length direction of the connecting component 100. The second tooth on the sixth rod 1000 meshes with the first tooth on the connecting plate 210, causing the first rod 200 and the second rod 300 to swing around the hinge point with the connecting component 100. The third rod 400 drives the fourth rod 500 and the fixing block 600 to move, so that the two fixing blocks 600 can move closer to each other. The anti-slip texture of the buffer layer 700 reliably grips the small strong magnet.

[0045] When it is necessary to release the strong magnet, the fifth rod 800 is released. Under the elastic force of the compression spring 900, the fifth rod 800 and the sixth rod 1000 are reset. The third rod 400 drives the fourth rod 500 and the fixed block 600 to move, thereby causing the two fixed blocks 600 to move away from each other, thus releasing the strong magnet.

[0046] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.
