[0001] This utility model relates to the field of clamps, and in particular to a spring clamp for clamping sheet metal. Background Technology
[0002] In industrial production, clamps are commonly used tools for holding and securing materials for subsequent processing or operations. However, existing clamps have several shortcomings: the end clamping structures of some glass or ceramic plate clamps use steel frames and pins, which are prone to breakage at the clamping points during transport, causing damage to the transported materials. Therefore, there is an urgent need for an improved clamp to solve these problems. Utility Model Content
[0003] Therefore, it is necessary to provide a spring clamp for holding plates to address the above problems.
[0004] A spring clamp for holding sheet metal includes a clamp body, which comprises an upper handle, a lower handle, and an elastic component. The upper and lower handles are rotatably connected by a pin, which passes through pre-set through holes in both handles, allowing them to rotate relative to each other around the pin's axis. Each handle has a spring-holding structure at its front end, comprising a first spring and a clamping pin. The first spring and clamping pin are disposed on a pre-set connecting portion of the upper handle, which has a hole adapted to the outer diameter of the first spring's end. The elastic component is arranged on the clamp body. A limiting block is also provided between the upper and lower handles.
[0005] The upper and lower grips are also provided with multiple mounting holes.
[0006] In one embodiment, the elastic component is a second spring, and the second spring is mounted between the upper grip and the lower grip through a mounting hole.
[0007] In one embodiment, the clamping surface of the clip is provided with anti-slip protrusions.
[0008] In one embodiment, the inner wall of the mounting hole on the fixture body is surface treated.
[0009] In one embodiment, the inner wall surface of the connector is specially treated.
[0010] In one embodiment, the gripping parts of the upper and lower grips are provided with an anti-slip structure, which is an anti-slip rubber layer.
[0011] In one embodiment, the clamp body, upper grip, lower grip, and clamp pins are all made of metal, and the first spring and the second spring are made of spring steel.
[0012] The aforementioned spring clamp for holding sheet metal, by setting a spring clamping structure and elastic components, and by setting anti-slip protrusions on the clamping pins, can prevent the clamping point from breaking when clamping and transporting materials, thus protecting the transported materials; the upper handle and the lower handle are rotatably connected by a pin, which makes operation flexible and easy to control the opening and closing of the clamp, improving work efficiency. The structural optimization of each component improves the overall performance of the clamp, extends its service life, reduces maintenance costs, and can meet the needs of production and processing.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] See Figures 1-4 A spring clamp for holding sheet metal includes a clamp body 1. The clamp body 1 includes an upper handle 11, a lower handle 12, and an elastic component. The upper handle 11 and the lower handle 12 are rotatably connected by a pin. The pin passes through a pre-set through hole 13 in each of the upper handle 11 and the lower handle 12, allowing the upper handle 11 and the lower handle 12 to rotate relative to each other around the axis of the pin, thereby achieving flexible opening and closing action. The front ends of the upper handle 11 and the lower handle 12 are provided with spring clamping structures 2. The spring clamping structure 2 includes a first spring 21 and a clamping pin 22. The first spring 21 and the clamping pin 22 are disposed on a pre-set connecting part 14 of the upper handle 11. The connecting part 14 has a hole that adapts to the outer diameter of the end of the first spring 21. The elastic component is arranged on the clamp body 1 to provide elastic support or reset function. The spring clamping structure 2 on the upper handle 11 is the same as the spring clamping structure 2 on the lower handle 12. A limiting block 3 is also provided between the upper grip 11 and the lower grip 12, and the limiting block 3 can limit the position of the clamp when holding the material;
[0023] The upper grip 11 and the lower grip 12 are also provided with a plurality of mounting holes 4; by providing the mounting holes 4, they can be fixedly connected to other components by bolts, pins and other connecting parts, so that the clamp can be used with different equipment or structures.
[0024] Furthermore, the elastic component is a second spring 5, and the second spring 5 is installed between the upper grip 11 and the lower grip 12 through the mounting hole 4; during the opening and closing of the clamp, elastic deformation occurs, which helps the clamp to return to its initial state.
[0025] Furthermore, the clamping surface of the clamp 22 is provided with anti-slip protrusions 221 to increase the contact friction with the material, enhance the clamping force on the material, and prevent the material from slipping.
[0026] Furthermore, the inner wall of the mounting hole 4 on the fixture body 1 undergoes surface treatment; the surface treatment is galvanizing or knurling to enhance the friction and connection stability with the connector and prevent loosening during use.
[0027] Furthermore, the inner wall surface of the connecting part 14 is roughened to enhance the friction with the end of the spring and the connection stability, and to prevent the spring from undergoing axial displacement during use.
[0028] Furthermore, the gripping parts of the upper grip 11 and the lower grip 12 are provided with an anti-slip structure, which is an anti-slip rubber layer 6.
[0029] Furthermore, the clamp body 1, upper handle 11, lower handle 12, and clamp pin 22 are all made of metal materials, and the first spring 21 and the second spring 5 are made of spring steel materials; this prevents hand slippage during operation and improves operational safety and comfort; the metal materials are aluminum alloy or carbon steel, which have sufficient strength and rigidity; the springs are made of spring steel materials to ensure good elasticity and service life.
[0030] It should be noted that, taking glass plate 7 as an example, when glass plate 7 needs to be transported and clamped, the operator holds the upper handle 11 and the lower handle 12, applying external force to compress the second spring 5 between the upper handle 11 and the lower handle 12, and rotates it around the pin, causing the clamping pins 22 and the first spring 21 on the upper handle 11 and the lower handle 12 to move in opposite directions. At this time, the front ends of the upper handle 11 and the lower handle 12 separate to form an opening, and the rear ends move closer to each other. The opening is placed into the glass plate 7. After the glass plate 7 touches the limiting block 3, the upper handle is then slowly released. The upper handle 11 and lower handle 12 reduce external force. The second spring 5, through its elastic restoring force, drives the ends of the upper handle 11 and lower handle 12 to move in opposite directions. The spring clamping structure 2 of the upper handle 11 and lower handle 12 clamps the glass plate 7. After the first spring 21 contacts the glass plate 7, it begins to compress until the anti-slip protrusions 221 of the clamping pins 22 of the upper and lower handles 12 touch the glass plate 7, thus completing the clamping of the glass plate 7. After transporting to the corresponding position, the step of applying external force is repeated to make the clamp detach from the glass plate 7. Multiple such clamps are used to achieve the clamping and transportation of the glass plate 7.
[0031] See Figure 5 In addition, throughout the process, the first spring 21 is elastic, which allows the glass plate 7 to swing up and down slightly, further preventing the clamping points of the glass plate 7 from being damaged due to excessive force.
[0032] The aforementioned spring clamp for holding sheet metal, by setting a spring clamping structure 2 and an elastic component, and by setting anti-slip protrusions 221 on the clamping pins 22, can prevent the clamping point from breaking when clamping and transporting materials, thus protecting the transported materials; the upper handle 11 and the lower handle 12 are rotatably connected by a pin, which makes the operation flexible and easy to control the opening and closing of the clamp, improving work efficiency. The structural optimization of each component improves the overall performance of the clamp, extends its service life, reduces maintenance costs, and can meet the needs of production and processing.
[0033] 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.
[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
