Description

Technical Field

[0001] This utility model relates to the field of clamping tool technology, and in particular to a convenient clamping device for plates. Background Technology

[0002] In decoration, furniture manufacturing, and panel installation sites, construction workers frequently need to move, flip, or temporarily secure various thin panels (such as gypsum board, plywood, aluminum composite panels, and sintered stone). Traditional methods have at least the following drawbacks: When lifting the board manually, the operator can only hold the bottom or side edge of the board with their fingers. The contact area is small and the pressure is strong, which makes it easy to cut the fingers. When the surface of the board is covered with dust or release agent, the risk of slipping is high. A 2400×1200×12 mm gypsum board often requires two people to work together, which results in high labor costs.

[0003] While vacuum suction cup lifting devices are labor-saving, they require an external power source or compressed air, and the equipment is bulky and expensive. When the surface of the board has uneven texture, damaged film, or is damp, the seal may fail, causing the suction cup to suddenly fall off, posing a significant safety hazard.

[0004] Traditional C-clamps and F-clamps, while offering adjustable clamping force, are perpendicular to the material and cannot be used as handles. Moving them requires either holding the material or using a pry bar, resulting in repetitive steps and low efficiency. Therefore, a solution is urgently needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a convenient clamping device for plates. The device has a simple structure, is easy to use, can quickly clamp objects, improve handling efficiency, and save labor.

[0006] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: a convenient clamping device for plates includes a handle, a support frame, an elastic element, an arc-shaped connecting rod, and a clamping plate; there are two support frames and two arc-shaped connecting rods, with one end of each support frame connected to the other, and the other end of each support frame connected to one end of an arc-shaped connecting rod; one end of the handle is rotatably connected to the connection end of the two support frames; both ends of the elastic element are connected to the connection points of the two support frames and the arc-shaped connecting rods, and the elastic element can deform under external pressure and automatically return to its original position after the external force is removed; the other ends of the two arc-shaped connecting rods are connected to the clamping plate.

[0007] Preferably, the elastic element is an arc-shaped spring steel.

[0008] Preferably, the arc-shaped connecting rod is hinged to the clamping plate.

[0009] Preferably, the inner surface of the clamping plate is provided with a plurality of anti-slip protrusions, and the anti-slip protrusions are made of rubber material.

[0010] Preferably, a handle is fixedly provided on the outer surface of the clamping plate.

[0011] The beneficial effects of this utility model are reflected in: (1) The clamping device provided by this utility model forms multi-point and surface contact by arranging rubber anti-slip protrusions on the entire inner side of the clamping plate, resulting in low pressure per unit area and making it difficult for the plate to slip or chip. The arc spring steel provides continuous and stable positive clamping force, and the clamping force does not decrease during walking, bumping, and flipping, thus avoiding injury from "suddenly dropping the plate" and significantly improving the safety of handling.

[0012] (2) When using the device provided by this utility model, only one person is needed to complete the whole process of “opening-insertion-releasing clamping-lifting and transporting-releasing”. No assistant is needed to hold the board, nor is it necessary to carry auxiliary equipment such as vacuum pumps and air pipes. On-site labor can be reduced, thereby simplifying the operation process and saving manpower.

[0013] (3) The device provided by this utility model utilizes the variable stiffness characteristics of the arc spring steel itself: the deformation is small and the clamping force is gentle when the plate is thin; the deformation is large and the clamping force increases synchronously when the plate is thick. There is no need to manually adjust the bolts or replace the springs. One clamp covers the specifications of commonly used decoration boards. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0017] Example See Figure 1-2As shown: This utility model provides a convenient clamping device for plates, including a handle 1, two support frames 2 and an arc-shaped spring steel 3.

[0018] One end of each of the two support frames 2 is connected to the other end, and the connecting end is rotatably connected to one end of the handle 1. The other end of each of the two support frames 2 is connected to an arc-shaped connecting rod 4. An arc-shaped spring steel 3 is placed between the two support frames 2. The arc-shaped spring steel 3 has the function of elastic deformation and energy storage, and the two ends of the arc-shaped spring steel 3 are respectively connected to the connection points of the two support frames 2 and the arc-shaped connecting rod 4.

[0019] A clamping plate 5 is hinged to one end of the arc-shaped connecting rod 4. Multiple anti-slip protrusions 6 are fixed on the inner surface of the clamping plate 5, and the anti-slip protrusions 6 are made of rubber material. A handle 7 is fixed on the outer surface of the clamping plate 5.

[0020] In practical use During the preparation phase: The operator holds both handles 7 with both hands at the same time. After the handles 7 are separated outward, they drive the clamping plates 5 to open outward around the hinge point. The arc-shaped connecting rod 4 pushes the support frame 2 to open around the pin of the handle 1. After that, the arc-shaped spring steel 3 is bent in the opposite direction to store energy. The opening of the two clamping plates 5 is increased to be large enough to insert the plate.

[0021] After inserting the board: maintain the external pulling force on the handle 7, move the device to the edge of the board, so that the board enters between the two clamping plates 5; at this time, the handle 1 is in a free hanging state and is not held by hand.

[0022] Automatic clamping: When handle 7 is released, the arc-shaped spring steel 3 releases its elastic potential energy and pushes the support frame 2 to rebound inward. Then, the rebound force is converted into a positive clamping force of the clamping plate 5 through the arc-shaped connecting rod 4, and the plate is continuously pressed; the rubber anti-slip protrusion 6 is deformed under pressure, providing high friction and preventing slippage.

[0023] Extracting the plate: After the clamping plate 5 has fully clamped the plate, the operator can hold the handle 1 located at the top of the device to lift, move or flip the entire plate with one hand; at this time, the curved spring steel 3 still maintains sufficient clamping force, and there is no need to hold the handle 7 during the handling process.

[0024] Quick release: After placing the board in the target position, pull out the handles 7 on both sides again to increase the opening of the clamping plate 5, and then pull out the device to complete one clamping-transfer-release cycle.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
