[0002] In a photovoltaic power plant, the photovoltaic mounting frame used to carry photovoltaic panels includes side frames and purlins. There are two main ways to connect and fix the side frames and purlins. One is bolt connection; the other is connection using special clamps. Connection using special clamps often requires special disassembly tools for disassembly.

A through hole is provided in the middle of the clamp, and clamping openings are provided on both sides of the front end of the clamp, through which the side frame and the purlin are clamped and fixed. When disassembling the clamp, the clamping opening needs to be expanded so that the clamping opening releases the side frame and the purlin. Since the clamp is generally made of metal material, it is difficult to disassemble by hand. Using some existing tools, such as screwdrivers, to expand the clamping opening easily damages the side frame and the purlin, and the disassembly efficiency is also low.

[0004] Therefore, it is urgent to propose a disassembly pliers to solve the above-mentioned technical problems. Utility Model Content

It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0039] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] This embodiment provides a disassembly pliers, which can realize the rapid disassembly of the clamp without damaging the side frame and the purlin, and the disassembly is labor-saving. It can be used for clamps of different shapes and has high universality.

[0041] like Figure 1 As shown, in a possible embodiment, the above-mentioned disassembly pliers are used to disassemble the installation clamp 10 of the side frame 20 and the purlin 30 of the photovoltaic module, and a through hole 12 is provided in the middle of the clamp 10, and two clamping openings 11 are provided at one end of the clamp 10 which are symmetrical with respect to the axis of the through hole 12, and the clamping openings 11 are connected to the through hole 12, and the side frame 20 and the purlin 30 are clamped and fixed by the two clamping openings 11.

[0042] Specifically, Figure 2-Figure 4 As shown, the disassembly pliers include two pliers bodies 100 connected together by rotation, one end of the two pliers bodies 100 located behind the rotation center is a handle end 110 driven by external force, and the other end located in front of the rotation center is an inner support end 120 used to open the clamping opening, and each inner support end 120 is detachably connected with an inner support member 130. The two handle ends 110 can drive the two inner support ends 120 to separate from each other under the drive of external force, so that the two inner support members 130 abut against the two ends of the clamp near the clamping opening, and the two ends are separated from each other, and the contact between the inner support member 130 and the end is a line contact.

[0043] Use these removal pliers to remove Figure 1 The specific process of the fixture 10 shown is as follows:

[0044] First, adjust the distance between the two inner support ends 120 so that the two inner support ends 120 extend into the through hole 12 of the clamp 10, and make the inner support member 130 on the inner support end 120 abut against the end of the clamp 10 close to the clamping opening 11, that is, abut against the inner wall of the through hole 12 close to the clamping opening 11;

[0045] Then, the handle end 110 is driven by external force to drive the two inner support ends 120 away from each other. The two inner support ends 120 moving away from each other will drive the two inner support members 130 to move away from each other synchronously, so that the two inner support members 130 jointly separate the end of the clamp 10 close to the clamping opening 11, thereby achieving the purpose of enlarging the clamping opening 11. After the clamping opening 11 is enlarged, the clamp 10 can be removed by moving the disassembly pliers.

[0046] The disassembly pliers provided in this embodiment can realize the rapid disassembly of the clamp, and will not touch the side frame 20 and the purlin 30 during the disassembly process, so the side frame 20 and the purlin 30 will not be damaged. By setting the contact between the inner support member 130 and the end as line contact, the contact area is larger than point contact, and it is more labor-saving in the process of disassembling the clamp. By setting the inner support member 130 to be detachable, the appropriate inner support member 130 can be replaced according to the shape of different clamps, thereby improving the universality of the disassembly pliers.

[0047] It is worth noting that, in addition to being used for disassembling the above-mentioned clamp 10, the disassembly pliers can also be used for other clamps that need to expand the clamping opening. In a possible embodiment, when disassembling a clamp of other structures, the inner support end 120 can be extended into the clamping opening, so that the inner support member 130 abuts against the side wall of the clamp for forming the clamping opening. That is, the disassembly pliers are flexible in use, and the disassembly method of the clamp can be flexibly adjusted according to the disassembly needs.

[0048] Optionally, continue to see Figure 2 and Figure 3 In this embodiment, when the two handle ends 110 are close to each other, the two inner support ends 120 are moved away from each other to expand the clamping opening. In this way, during the process of disassembling the clamp, the thumb of the operator's hand abuts against one of the pliers 100, and the other four fingers abut against the other pliers 100, and the two inner support ends 120 can be moved away from each other by squeezing hard to expand the clamping opening. It is convenient to apply force and can be operated with one hand, which improves the efficiency of disassembling the clamp and reduces the difficulty of disassembling the clamp.

[0049] Furthermore, if Figure 2 , Figure 3 and Figure 5As shown, one of the two handle ends 110 is provided with a stopper 200, and the stopper 200 can abut against the side wall of the other handle end 110 to limit the two handle ends 110 from getting closer. When the two handle ends 110 are held tightly by hand, so that one of the handle ends 110 drives the stopper 200 thereon to abut against the other handle end 110, it indicates that the clamping opening of the clamp has been expanded to the required size, and the clamp can be easily removed. That is, the setting of the stopper 200 has a reminder effect on the operator, preventing the operator from wasting energy by expanding the clamping opening excessively, thereby reducing the operator's work intensity.

[0050] It is worth noting that when the disassembly pliers are used to disassemble Figure 1 In the clamp 10 shown, when the limiting member 200 abuts against the side wall of the other handle end 110, the maximum distance between the two inner support members 130 should be greater than the inner diameter of the through hole 12 to ensure that the clamping opening 11 is expanded.

[0051] Optionally, continue to see Figure 2 The handle end 110 is provided with an elongated hole 111 extending along the length direction of the handle end 110. The stopper 200 includes a bolt 210 and a nut 220. The bolt 210 is passed through the elongated hole 111 and connected to the nut 220. When the two handle ends 110 approach each other, the bolt 210 on the handle end 110 with the bolt 210 can abut against the side wall of the other handle end 110 to limit the two handle ends 110 from approaching each other. With such a configuration, the bolt 210 can be fixed at any position in the extending direction of the elongated hole 111 by the nut 220 to adjust the shortest distance between the two handle ends 110, that is, to adjust the farthest distance between the two inner support members 130, so that it can be applied to various types of clamps and has high universality.

[0052] Furthermore, if Figure 6 As shown, a limit baffle 121 is provided on one of the two inner support ends 120, and the limit baffle 121 can abut against the side wall of the other inner support end 120 to limit the two inner support ends 120 from further approaching. In addition, when the limit baffle 121 abuts against the side wall of the other inner support end 120, the distance between the two inner support ends 120 is greater than the total thickness of the workpiece clamped by the clamp. With such a configuration, when the two inner support ends 120 are extended into the clamp, the workpiece clamped by the clamp will enter the gap between the two inner support ends 120 to ensure that the inner support ends 120 can be extended into place, thereby improving the reliability of the disassembly clamp of the disassembly pliers. In addition, the configuration of the limit baffle 121 can facilitate the operator to adjust the disassembly pliers to the initial working state, thereby reducing the difficulty of operation.

[0053] like Figure 4 As shown, use this removal pliers to remove Figure 1In the clamp 10 shown, when the limit stopper 121 abuts against the side wall of the other inner support end 120, the distance between the two inner support ends 120 is greater than the total thickness of the side frame 20 and the purlin 30. The distance between the two inner support members 130 is smaller than the inner diameter of the through hole 12 to ensure that the two inner support members 130 can enter the through hole 12.

[0054] Further, see Figure 2 and Figure 3 One of the two clamp bodies 100 is the first clamp body 101, and the other is the second clamp body 102. The angle between the inner support end 120 of the first clamp body 101 and the handle end 110 is a, and the angle between the inner support end 120 of the second clamp body 102 and the handle end 110 is b, and a and b satisfy: a<b≤90°. In this way, while ensuring that the first clamp body 101 and the second clamp body 102 can reliably expand the clamping mouth, it can avoid the photovoltaic component on the top of the inner support end 120 from interfering with the operation of the handle, reducing the difficulty of disassembly.

[0055] In this embodiment, the included angle b between the inner supporting end 120 of the second pliers body 102 and the handle end 110 is 90°.

[0056] Furthermore, if Figure 2 and Figure 8 As shown, the disassembly pliers further include a rotating connection member 300. The rotation centers of the two pliers bodies 100 are each provided with a rotating connection hole 140. The rotating connection member 300 is passed through the two rotating connection holes 140. The rotating connection member 300 is detachable. The rotation connection of the two pliers bodies 100 is achieved by arranging the cooperation between the rotating connection member 300 and the rotating connection hole 140, and the rotation smoothness is better. By arranging the rotating connection member 300 to be detachable, the disassembly and maintenance between the two pliers bodies 100 is facilitated.

[0057] Optionally, in one possible embodiment, the rotating connector 300 is a bolt and nut assembly. In another possible embodiment, the rotating connector 300 may also be a pin and cotter pin assembly. In other embodiments, the structure of the rotating connector 300 may also be other, which can be set according to actual needs, and this application does not make specific limitations.

[0058] Alternatively, if Figure 7 and Figure 8 As shown, in this embodiment, the inner support member 130 is provided with a mounting groove 131, and the mounting groove 131 is interference-fitted with the inner support end 120. Such a configuration facilitates the installation and replacement of the inner support member 130.

[0059] Further, see Figure 8The inner support end 120 includes a main body 1201 and a mounting section 1202 disposed at the end of the main body 1201. A limiting surface 1203 is formed between the mounting section 1202 and the main body 1201. The limiting surfaces 1203 of the two pliers 100 are located in the same plane. The mounting groove 131 is interference-fitted with the mounting section 1202. The side wall of the inner support member 130 abuts against the limiting surface 1203. By limiting the installation of the inner support member 130 through the limiting surface 1203, the installation accuracy and efficiency of the inner support member 130 can be improved. By setting the limiting surfaces 1203 of the two pliers 100 in the same plane, the two inner support members 130 can be arranged relative to each other, so that when the clamp is disassembled, the points of action of the two inner support members 130 on the clamp correspond to each other, which can make the disassembly more labor-saving.

[0060] Optionally, continue to see Figure 7 In this embodiment, the inner support member 130 includes an inner support surface 132, which contacts the clamp during the process of disassembling the clamp, and the inner support surface 132 is a curved surface that can fit the clamp. Figure 1 Of course, in other embodiments, the shape of the inner support surface 132 can also be set to other shapes, which can be matched with the shape of the fixture.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
