[0034] Please combine Figure 1-4 The clamping device 100 of the embodiment of the present application includes a mounting base 10, a handle 20, a connecting member 30 and a plurality of clamping arms 40, wherein the handle 20 is rotatably disposed on the mounting base 10, and the connecting member 30 is connected to one end of the handle 20; the clamping arm 40 is movably disposed on the mounting base 10, and one end of each clamping arm 40 is movably connected to the connecting member 30. When the handle 20 rotates, the connecting member 30 is driven to move along the first direction to drive the clamping arm 40 to rotate.
[0035] In the clamping device 100 of the embodiment of the present application, when the handle 20 is rotated, the connecting member 30 is driven to move along the first direction to drive the clamping arm 40 to rotate, so that the multiple clamping arms 40 can work together to clamp and grasp or release small splicing parts. In this way, direct manual clamping of parts can be avoided, reducing the risk of personal injury. The use of the clamping device 100 also improves the semi-automatic efficiency of the machine. In addition, the clamping device 100 composed of the mounting base 10, the handle 20, the connecting member 30 and the clamping arm 40 has a simple and reliable structure and is easy to operate.
[0036] Specifically, the clamping device 100 is used to grasp small items. In the present embodiment, the clamping device 100 can be used to grasp small splicing product parts. It can be understood that small splicing products have some operating risks and are inconvenient to take and place. Manual direct clamping of items can easily cause personal injury. Therefore, manual operation of the clamping device 100 to grasp and carry small splicing product parts can reduce the risk of personal injury. At the same time, direct clamping by the clamping device 100 can also improve work efficiency.
[0037] The shape of the small object clamped by the clamping device 100 can be a regular shape or an irregular shape, that is, the shape of the small object can be diverse and not limited to a single shape. For example, in some examples, the shape of the small object can be a rectangle, another example, the shape of the small object can be a square, and another example, the shape of the small object can be a polygon. In this way, the clamping device 100 can be adapted to different splicing products, thereby improving the compatibility of the clamping device 100 with the splicing products.
[0038] The clamping device 100 can be made of a lightweight and high-strength alloy material. For example, the clamping device 100 is made of an aluminum alloy material. In this way, the clamping device 100 is lightweight while ensuring strength, which is convenient for users to use and improves work efficiency.
[0039] Please further combine Figure 1 The clamping device 100 may include a mounting seat 10, a handle 20, a connecting piece 30 and a clamping arm 40, wherein the mounting seat 10 constitutes a frame of the clamping device 100, and the handle 20, the connecting piece 30 and the clamping arm 40 may be respectively mounted on the mounting seat 10, thereby forming the clamping device 100 capable of grasping an object. The handle 20 and the clamping arm 40 may be respectively mounted on opposite sides of the mounting seat 10, and the handle 20 and the clamping arm 40 may both rotate relative to the mounting seat 10, and the handle 20 may be movably connected to the clamping arm 40 through the connecting piece 30.
[0040] Under the action of external force, the handle 20 can rotate around the mounting seat 10, thereby driving the connecting member 30 to move along a first direction, wherein the first direction can be the axial direction or vertical direction of the connecting member 30, and then the connecting member 30 drives the clamping arm 40 to rotate around the mounting seat 10, so that the clamping arm 40 can grab or unload objects. For example, please combine Figure 3 When the user presses down the handle 20 away from the end of the connector 30, the handle 20 rotates around the mounting base 10, driving the connector 30 to move upward in the first direction, and then driving the clamping arm 40 to rotate around the mounting base 10, so that the clamping arm 40 can clamp the small splicing parts. Figure 4When the user releases the handle 20 away from one end of the connecting member 30, the handle 20 rotates around the mounting base 10, driving the connecting member 30 to move downward along the first direction, and then driving the clamping arm 40 to rotate around the mounting base 10, so that the clamping arm 40 can loosen the small splicing part.
[0041] The number of the clamping arms 40 may be 2, 3, 4, 5 or even more, and the specific number is not limited. The multiple clamping arms 40 are used to clamp or grab items together. For example, in some embodiments, the number of the clamping arms 40 may be two, and the two clamping arms 40 are symmetrically arranged relative to the connecting member 30. For another example, in some embodiments, the number of the clamping arms 40 is 3, and the three clamping arms 40 are arranged circumferentially along the axis of the connecting member 30, and the three clamping arms 40 are used to clamp items together. For another example, in some embodiments, the number of the clamping arms 40 is 4, and two of the four clamping arms 40 are symmetrically arranged about the axis of the connecting member 30, and the four clamping arms 40 are used to clamp items together.
[0042] Please further combine Figure 1 and Figure 2 In some embodiments, the clamping device 100 further includes a reset elastic member 50 , which is compressed and disposed between the handle 20 and the connecting member 30 .
[0043] The resetting elastic member 50 may be a compression spring, for example, a coil spring, a leaf spring, a torsion bar spring, a gas spring or a rubber spring, etc., which is not specifically limited here.
[0044] When external force acts on the handle 20, the handle 20 rotates around the mounting seat 10, driving the connecting member 30 to move upward along the first direction, thereby driving the clamping arm 40 to rotate around the mounting seat 10, so that the clamping arm 40 can clamp the small splicing parts. At the same time, the connecting member 30 and the mounting seat 10 jointly press the reset elastic member 50 to produce elastic deformation. When the external force of the handle 20 disappears, the handle 20 rotates around the mounting seat 10, and the compressed reset elastic member 50 drives the connecting member 30 to move downward along the first direction, thereby driving the clamping arm 40 to rotate around the mounting seat 10, so that the clamping arm 40 can loosen the small splicing parts.
[0045] In this way, when the clamping device 100 places the spliced product, the user only needs to stop applying force to the handle 20 and rely on the spring force to reset and loosen the handle 20, which saves time and effort and improves the user experience of the clamping device 100.
[0046] See also Figure 1In some embodiments, the handle 20 includes a limiting protrusion 21, the mounting base 10 includes a fixed mounting member 11, the fixed mounting member 11 includes a limiting groove 111 and a hinge pin 60, the hinge pin 60 is located in the limiting groove 111, and the limiting protrusion 21 is rotatably connected to the hinge pin 60.
[0047] In this way, the handle 20 can be installed on the mounting seat 10 and rotate around the mounting fixing member 11, so as to drive the clamping arm 40 to clamp or open through the connecting member 30, so as to realize the grabbing or putting down of the splicing products.
[0048] In some embodiments, the handle 20 includes a first end and a second end opposite to each other, the first end is movably connected to the connecting member 30 , and the distance between the first end and the limiting protrusion 21 is smaller than the distance between the second end and the limiting protrusion 21 .
[0049] In this way, the user can save effort when grabbing splicing products through the clamping device 100, thereby reducing the difficulty of operating the clamping device 100.
[0050] Specifically, the handle 20 forms a lever on the fixed mounting member 11 with the limiting protrusion 21 as a fulcrum, and the first end and the second end are the two ends of the lever, and the first end of the handle 20 is a connecting end for movably connecting with the connecting member 30, and the second end of the handle 20 is a gripping end for the user to grip. It can be understood that the distance between the first end and the limiting protrusion 21 is smaller than the distance between the second end and the limiting protrusion 21. Due to the principle of the lever, the user can apply a smaller force to the gripping end to rotate the handle 20, thereby driving the clamping arm 40 to rotate to achieve grasping, so that when the user uses the clamping device 100 to grasp splicing products, the force applied to the handle 20 can be reduced, thereby improving the user experience.
[0051] See also Figure 1 and Figure 2 In some embodiments, the mounting base 10 further includes a plurality of support members 12 , and the support members 12 extend from the fixed mounting member 11 along a first direction to be movably connected to the clamping arm 40 .
[0052] Specifically, the number of the support members 12 is the same as the number of the clamping arms 40, and the plurality of support members 12 are arranged at intervals along the circumferential direction of the connecting member 30. The support members 12 include two opposite ends, one end of each support member 12 is fixedly connected to the fixed mounting member 11, and the other end is rotatably connected to the clamping arm 40, and the clamping arm 40 can rotate around the support member 12, thereby realizing the grabbing or putting down of the object.
[0053] The connection method between the support member 12 and the fixed installation member 11 may include but is not limited to screw connection, welding, riveting, etc. For example, the support member 12 and the fixed installation member 11 may be screwed, so that the disassembly, assembly and replacement of the support member 12 can be facilitated.
[0054] In this way, through the setting of the support member 12, the clamping arm 40 can be rotatably set on the support member 12. When the handle 20 is subjected to external force, the clamping arm 40 is driven to rotate around the support member 12 through the connecting member 30, thereby realizing the clamping or opening of the clamping arm 40, thereby realizing the grasping or putting down of the splicing product by the clamping device 100.
[0055] In some embodiments, the clamping arm 40 is connected to the support member 12 via a hinge.
[0056] Specifically, the clamping arm 40 may be provided with an open slot, in which a hinge pin 60 is provided, and the support member 12 partially extends into the open slot and is connected to the hinge pin 60. It can be understood that the hinge connection has the advantages of strong load bearing capacity, simple structure, convenient disassembly and maintenance, and good hinge function. Therefore, the clamping arm 40 and the support member 12 are connected through the hinge to effectively ensure that the clamping arm 40 is reliably connected to the fixed mounting member 11, and the clamping arm 40 can be rotated relative to the support member 12 to achieve the clamping or opening function.
[0057] In some embodiments, the connecting member 30 includes a concentric block 31 that is hingedly connected to the clamping arm 40 .
[0058] In this way, by hingedly connecting the concentric block 31 and the multiple clamping arms 40, the concentric block 31 and the clamping arms 40 can be rotationally connected and reliably connected, so that the concentric block 31 can drive the multiple clamping arms 40 to clamp and release at the same time, making the clamping device 100 compact, small and light.
[0059] In some embodiments, the connecting member 30 further includes a guide shaft 32, one end of which is movably connected to the handle 20, and the other end of the guide shaft 32 is connected to the concentric block 31. The axial extension direction of the guide wire shaft is the first direction.
[0060] Specifically, the fixed mounting member 11 is provided with a through hole, one end of the guide shaft 32 passes through the through hole and is movably connected to the handle 20 , and the other end of the guide shaft 32 is detachably connected to the concentric block 31 .
[0061] In some embodiments, the guide shaft 32 is connected to the concentric block 31 via threads.
[0062] In this way, the guide shaft 32 and the concentric block 31 are connected by threads, which can facilitate the installation and disassembly of the guide shaft 32 and the concentric block 31.
[0063] See also Figure 2 In some embodiments, the handle 20 is further provided with a through slot 22 , on which a rotating pin 23 is provided, and the guide shaft 32 passes through the through slot 22 and is detachably connected to the rotating pin 23 .
[0064] Specifically, the through slot 22 is opened at the first end of the handle 20, and the through slot 22 can be a U-shaped slot. The rotating pin 23 is detachably arranged on the through slot 22. The guide shaft 32 passes through the through slot 22 and is rotatably connected with the rotating pin 23 located on the through slot 22. When the rotating pin 23 is removed, the handle 20 is rotated to make the guide shaft 32 disengage from the through slot 22 and separate from the handle 20.
