Clamping tool

Abstract

The present application relates to a clamping tool. The clamping tool comprises: a support body, a first clamping member, a second clamping member and a movable component. The first clamping member and the second clamping member are spaced apart on the support body, and a clamping space for placing the photovoltaic frame is formed therebetween. The movable component is movably connected to the support body and is rotationally connected to at least one of the first clamping member and the second clamping member, and the movable component is used to drive at least one of the first clamping member and the second clamping member to move so that the first clamping member and the second clamping member move closer to or away from each other. By using the clamping tool, employees' fingers are prevented from directly contacting the photovoltaic frame, reducing the risk of crushing injuries. In addition, since the clamping tool can quickly loosen the photovoltaic frame by rotating the movable component, the action consistency is high, which can reduce shaking when placing the photovoltaic frame, thereby reducing the risk of hidden cracks.

Description

Technical Field

[0001] The present application relates to the technical field of tools, and in particular to a clamping tool. Background Art

[0002] The photovoltaic frame usually includes side A, side B, side C and side D, where side A is the top surface of the photovoltaic frame, side B is the side outside the photovoltaic frame, side C is the bottom surface of the photovoltaic frame, and side D is the side inside the photovoltaic frame. A placement groove is formed under side A to place the solar cell.

[0003] At present, in order to reduce the production cost of photovoltaic frames, the width of the C side of the short frame in the photovoltaic frame is usually shortened, or even no C side is set. In the production workshop, when the assembly line fails or other abnormal conditions occur, the photovoltaic frames will fill the assembly line. In order to reduce losses and maximize production capacity, it is necessary to manually lift and lower the photovoltaic frames from the assembly line. The photovoltaic frames are generally placed with the C side facing up and the A side facing down, and flow along the direction of the long frame of the photovoltaic frame on the assembly line. Personnel can only stand at both ends of the short frame to carry the components. When the short frame has a short C side or no C side, since there is no fulcrum on the C side to lift up, you can only reach your hand into the placement slot below the A side of the photovoltaic frame to lift it up. On the one hand, lifting in this way is easy to crush people's fingers, and on the other hand, the unstable movement of the personnel in the process of pulling out their fingers will cause shaking, which is easy to cause hidden cracks in the photovoltaic frame. Utility Model Content

[0004] Based on this, it is necessary to provide a clamping tool to address the current problems that on the one hand, people's fingers are easily crushed during the process of lifting the photovoltaic frame, and on the other hand, the shaking caused by people pulling their fingers away can easily cause hidden cracks in the photovoltaic frame.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0028] See also Figure 1 (b), the photovoltaic frame 2000 generally includes an A surface 201, a B surface 202, a C surface 203 and a D surface 204, and a placement groove 205 is used to place solar cells.

[0029] See also Figure 1 (a) and (b), in order to reduce the production cost of the photovoltaic frame 2000, the width of the C surface 203 of the short frame 200 of the photovoltaic frame 2000 is usually shortened, or even the C surface 203 of the short frame 200 is eliminated. In the production workshop, when the assembly line fails or other abnormal conditions occur, the photovoltaic frames 2000 will fill up the assembly line. In order to reduce the loss and maximize the production capacity, it is necessary to manually lift and lower the photovoltaic frames 2000 from the assembly line. The photovoltaic frames 2000 are generally placed with the C surface 203 facing up and the A surface 201 facing down, and flow along the direction of the long frame 100 of the photovoltaic frame 2000 on the assembly line. The personnel can only stand at both ends of the short frame 200 to carry it. Since the C surface 203 of the short frame 200 is placed upward, there is no fulcrum for lifting it upward, and the only way is to reach into the placement groove 205 below the A surface 201 of the photovoltaic frame 2000 to lift it upward. On the one hand, lifting in this way can easily crush people's fingers. On the other hand, the unstable movement of people in the process of pulling their fingers away will cause shaking, which can easily cause hidden cracks in the photovoltaic frame 2000.

[0030] Based on this, see Figure 3 and Figure 6, an embodiment of the present application provides a clamping tool 1000, including a support body 1, a first clamping member 2, a second clamping member 3 and a movable component 4. The first clamping member 2 and the second clamping member 3 are spaced apart on the support body 1, and a clamping space for placing the photovoltaic frame 2000 is formed therebetween. The movable component 4 is movably connected to the support body 1, and is rotationally connected to at least one of the first clamping member 2 and the second clamping member 3. The movable component 4 is used to drive at least one of the first clamping member 2 and the second clamping member 3 to move so that the first clamping member 2 and the second clamping member 3 move closer to or away from each other. Due to the use of the clamping tool 1000, employees' fingers are prevented from directly contacting the photovoltaic frame 2000, reducing the risk of crushing injuries. The photovoltaic frame 2000 can be quickly released through the movable component 4, and the action consistency is high. It can reduce shaking when placing the photovoltaic frame 2000, thereby reducing the risk of hidden cracks. Furthermore, at least one of the first clamping member 2 and the second clamping member 3 is rotatably connected to the movable component 4, so that the clamping member has a soft contact when contacting the photovoltaic frame 2000, thereby avoiding collision with the photovoltaic frame 2000.

[0031] The movable component 4 may be movably connected to the support body 1 by sliding connection or rotating connection, both of which can be used to drive at least one of the first clamping member 2 and the second clamping member 3 to move.

[0032] See also Figure 2 and Figure 3 In some embodiments, the first clamping member 2 is fixedly connected to the support body 1, and the second clamping member 3 is rotatably connected to the movable assembly 4. The movable assembly 4 drives the second clamping member 3 to move closer to or away from the first clamping member 2 to clamp or release the photovoltaic frame 2000. This arrangement can save the volume of the clamping tool 1000, so that it can clamp the photovoltaic frame 2000 in a relatively small working area.

[0033] See also Figure 3 In some embodiments, the support body 1 includes a first portion 11 and a second portion 12 connected in a bent manner, the first clamping member 2 is fixedly connected to the first portion 11 and arranged opposite to the second portion 12, and the movable component 4 is movably connected to the second portion 12. Compared with rotatably connecting the movable component 4 to an end of the first portion 11 away from the first clamping member 2, adding the second portion 12 can increase the supporting force of the support body 1 on the movable component 4 and improve the clamping stability of the clamping tool 1000.

[0034] See also Figure 3Further, along the extension direction of the first clamping member 2, the length of the second portion 12 is less than the length of the first clamping member 2, and the end of the second portion 12 away from the first portion 11 is rotatably connected with the movable component 4. In order to ensure that the second portion 12 does not interfere with the rotation of the movable component 4, the length of the second portion 12 is set to be less than the length of the first clamping member 2, so that a space with a height difference is constructed between the second portion 12 and the first clamping member 2, so that the movable component 4 can rotate in the space.

[0035] See also Figure 3 In some embodiments, the movable assembly 4 includes two movable members 44 and a handle 45 arranged in pairs, one end of the two movable members 44 is connected by the handle 45, and the other ends are arranged at intervals to be movably connected to the two sides of the support body 1. The paired movable members 44 can provide a more stable clamping force, and the handle 45 is arranged for easy gripping.

[0036] See also Figure 4 In some embodiments, each movable member 44 includes a bent and connected rotating portion 42 and a hand-held portion 43. The rotating portion 42 is rotatably connected to the support body 1 and is rotatably connected to the second clamping member 3. Figure 3 The handle portion 43 is at least partially located above the support body 1, and the handle portion 43 is used to move upward or downward to rotate the rotating portion 42, thereby driving the second clamping member 3 to move closer to or away from the first clamping member 2. By adding the handle portion 43, the second clamping member 3 can be moved toward the first clamping member 2 by pulling the handle portion 43 upward, which is more labor-saving and efficient.

[0037] See also Figure 2 , Figure 3 and Figure 4 , illustratively, an embodiment of the present application provides a method for using a clamping tool 1000, which is to press down the handle 45 of the movable component 4 so that the rotating part 42 drives the second clamping member 3 away from the first clamping member 2, so that the photovoltaic frame 2000 is located in the clamping space, and lift the handle 45 so that the rotating part 42 drives the second clamping member 3 to move closer to the first clamping member 2 to clamp the photovoltaic frame 2000.

[0038] See also Figure 5 and Figure 6In some embodiments, the movable component 4 includes two groups, and the two groups of movable components 4 are respectively movably connected to the opposite sides of the support body 1, and the first clamping member 2 and the second clamping member 3 are respectively corresponding to the two groups of movable components 4. The two groups of movable components 4 respectively drive the first clamping member 2 and the second clamping member 3 to move toward or away from each other to get closer or farther away. Since two groups of movable components 4 are provided, the first clamping member 2 and the second clamping member 3 can both move flexibly, the size of the clamping space can be better adjusted, the clamping flexibility of the clamping tool 1000 is improved, and the first clamping member 2 and the second clamping member 3 can evenly apply clamping force to the photovoltaic frame 2000 to avoid the deflection or tilt of the photovoltaic frame 2000.

[0039] See also Figure 6 In some embodiments, in the two groups of movable components 4, each group of movable components 4 includes two movable parts 44 and a handle 45 arranged in pairs, one end of the two movable parts 44 is connected by the handle 45, and the other ends are arranged at intervals to be movably connected to the two sides of the support body 1. In this way, the clamping stability of the two groups of movable components 4 can be improved.

[0040] See also Figure 6 In some embodiments, the movable member 44 of each group of movable components 4 includes a rotating portion 42 and a hand-held portion 43 connected by bending, the first clamping member 2 and the second clamping member 3 are respectively connected to the two rotating portions 42, the rotating portions 42 are respectively connected to the opposite sides of the support body 1, the two hand-held portions 43 are located above the support body 1, and the openings of each group of movable components 4 are arranged to face each other at the bending angle. The hand-held portions 43 are added, and by pulling the two hand-held portions 43 upward, the two rotating portions 42 drive the first clamping member 2 and the second clamping member 3 to move closer to each other, thereby saving more effort and being more efficient.

[0041] See also Figure 7 (a), in some embodiments, the support body 1 includes a first portion 11 and two second portions 12 connected in a bent manner, the two second portions 12 are arranged on the same side of the first portion 11 and are arranged opposite to each other, and the two groups of movable components 4 are respectively movably connected to the two second portions 12. Compared with movably connecting the two groups of movable components 4 at both ends of the first portion 11, adding two second portions 12 to the support body 1 can better provide support for the two movable components 4, allowing them to move more stably.

[0042] Illustratively, the embodiment of the present application provides another method of using the clamping tool 1000, which is to simultaneously press down the handles 45 of the two movable components 4 so that the two movable components 4 respectively drive the first clamping member 2 and the second clamping member 3 away from each other, so that the photovoltaic frame 2000 is located in the clamping space, and at the same time lift up the handle 45 so that the two movable components 4 respectively drive the first clamping member 2 and the second clamping member 3 closer to each other to clamp the photovoltaic frame 2000.

[0043] See also Figure 3 , Figure 4 , Figure 6 and Figure 7 In some embodiments, the movable component 4 is penetrated by a first mounting hole 41, and the first clamping member 2 and / or the second clamping member 3 is penetrated by a second mounting hole 31. The movable component 4 is rotatably connected to the first clamping member 2 and / or the second clamping member 3 by simultaneously penetrating the first mounting hole 41 and the second mounting hole 31 through the first fastener 5, which facilitates disassembly and assembly and makes the structure compact.

[0044] There are the following optional implementations but are not limited to, in one implementation, see Figure 3 and Figure 4 The first clamping member 2 is fixedly connected to the support body 1, the second clamping member 3 is rotatably connected to the movable component 4, the second clamping member 3 is penetrated with a second mounting hole 31, and the movable component 4 is rotatably connected to the second clamping member 3 through the first fastener 5 which penetrates the first mounting hole 41 and the second mounting hole 31. Figure 3 In this manner, the axes of the first fastener 5 and the second fastener 6 are aligned along the extension direction of the second portion 12 of the support body 1, thereby positioning the second clamping member 3 on the inner side of the second portion 12 of the support body 1, so that the second portion 12 can abut against the second clamping member 3, thereby preventing the second clamping member 3 from turning out of the support body 1 relative to the movable component 4, thereby improving the clamping stability.

[0045] See also Figure 6 In another optional manner, the first clamping member 2 and the second clamping member 3 are rotatably connected to the two movable components 4 respectively. Figure 7 (b), Figure 7 (b) shows that the second clamping member 3 is provided with a second mounting hole 31, and the first clamping member 2 is also provided with a second mounting hole 31. Figure 6 The two movable components 4 are rotatably connected to the first mounting holes 41 (not shown in the figure) on the first clamping member 2 and the second clamping member 3 through the second mounting holes 31 provided by the two first fasteners 5 respectively.

[0046] See also Figure 6 In some embodiments, the movable component 4 is provided with a third mounting hole 421, see Figure 7 (a) The support body 1 is penetrated by the fourth mounting hole 13, and the movable component 4 is penetrated by the third mounting hole 421 and the fourth mounting hole 13 through the second fastener 6 to be rotatably connected to the support body 1, which can facilitate assembly and disassembly.

[0047] Furthermore, the third mounting holes 421 on the two groups of movable components 4 are long strip holes, and the long strip holes have a first end and a second end relative to each other along their length direction, the first end being an end close to the inside of the support body 1, and the second end being an end close to the outside of the support body 1. The connection position of the second fastener 6 can be located at any position between the first end and the second end. When the second fasteners 6 on both sides are connected to a position close to the first end, the distance between the first clamp 2 and the second clamp 3 is widened, and it can adapt to a photovoltaic frame 2000 with a larger width. When the second fasteners 6 on both sides are connected to a position close to the second end, the distance between the first clamp 2 and the second clamp 3 is narrowed, and it can adapt to a photovoltaic frame 2000 with a smaller width. In this way, it is possible to flexibly adapt to the width size of the photovoltaic frame 2000 for clamping.

[0048] For example, the first fastener 5 and the second fastener 6 may be bolts, screws, etc.

[0049] Exemplarily, the first clamping member 2 and the second clamping member 3 may be in the shape of a square plate, or a semicircular plate, a trapezoidal plate, etc. The opposing surfaces of the first clamping member 2 and the second clamping member 3 may be provided with anti-slip members, such as anti-slip rubber strips or anti-slip rubber plates, etc.
