[0042] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] Embodiment 1:

[0044] Please refer to Figure 1 , Figure 1 A schematic diagram of a structure of a device for preventing a counterweight from falling off when installing a junction box provided by an embodiment of the utility model. The device may include:

[0045] Articulator frame 10, connecting component 20 and crimping component 30;

[0046] One end of the articulator frame 10 abuts against the first surface of the junction box 50;

[0047] The connecting member 20 is connected to the articulator frame 10 to form a revolute pair, and the first connecting end of the connecting member 20 extends to the inner side of the articulator frame 10, and the second connecting end of the connecting member 20 extends to the outer side of the articulator frame 10;

[0048] One end of the crimping component 30 is hinged to the first connecting end, and the other end of the crimping component 30 abuts against the second surface of the junction box 50, so that when the counterweight block 60 is connected to the second connecting end and the connecting component 20 is driven to rotate, the crimping component 30 is driven to rotate in the opposite direction of the connecting component 20; the first surface and the second surface are two surfaces that are aligned with each other for the junction box 50.

[0049] It should be noted that in this embodiment, the photovoltaic module 1 is mostly arranged vertically during assembly, and the junction box 50 is connected to the back surface of the photovoltaic module 1. In this embodiment, one end of the articulator frame 10 abuts against the first surface of the junction box 50, and the crimping component 30 hinged to the connecting component 20 abuts against the second surface of the junction box 50. When the second connecting end of the connecting component 20 is connected to the counterweight 60, the connecting component 20 is driven to rotate, and because the crimping component 30 is hinged to the connecting component 20, when the connecting component 20 rotates, the crimping component 30 is driven to rotate in the opposite direction of the connecting component 20, so that the crimping component 30 forms a tendency to move toward the direction of the junction box 50, so as to form a snap-fit ​​engagement between the first surface and the second surface of the junction box 50. It should be further explained that, in order to ensure that the crimping component 30 can press down the junction box 50 and form a tendency to move toward the inside of the junction box 50 when the second connection end is connected to the counterweight 60, it is necessary to ensure that the crimping component 30 in contact with the second surface of the junction box 50 does not reach directly below the hinge point between the crimping component 30 and the connection component 20 when the second connection end is not connected to the counterweight 60, that is, the lowest point of the crimping component 30 rotating along the hinge point should be located inside the junction box 50, that is, the distance from the contact point between the crimping component 30 and the second surface of the junction box 50 to the hinge point is greater than the distance between the hinge point and the second surface of the junction box 50. In this embodiment, the connection component 20 can be set as a ball head connection rod, and the corresponding articulator frame 10 is correspondingly provided with a limit guide groove adapted to the position of the ball head.

[0050] In this embodiment, the connecting component 20 rotates along the connection point with the articulator frame 10, that is, one end of the connecting component 20 extends to the side of the articulator frame 10 close to the terminal box 50, and the other side of the connecting component 20 extends to the side of the articulator frame 10 facing away from the terminal box 50. This embodiment does not limit the specific way in which the connecting component 20 is connected to the counterweight 60. For example, the connecting component 20 can be fixedly connected to the counterweight 60, or the connecting component 20 can be movably connected to the counterweight 60. The above-mentioned connecting component 20 and the counterweight 60 can be movably connected, that is, the connection between the connecting component 20 and the counterweight 60 can be relatively displaced. This embodiment does not limit the specific structure of the articulator frame 10, as long as one end can abut against the first surface of the terminal box 50 and is provided with a shape that is connected to the connecting component 20 to form a rotating pair. For example, the articulator frame 10 can be set to have articulator frame substructures formed on at least two adjacent surfaces of the junction box 50, and the articulator frame substructure corresponding to the first surface of the junction box 50 can be abutted against the junction box 50, and the other articulator frame substructure can be connected to the connecting component 20, wherein each articulator frame substructure corresponds to one side surface of the junction box 50. This embodiment does not limit the specific shape and structure of the crimping component 30, as long as the shape and material can form friction with the surface of the junction box 50. It should be further explained that in this embodiment, the crimping component 30 uses a material with a larger friction coefficient with the surface of the junction box 50, and the effect of the device and the junction box 50 is better. Correspondingly, the specific shape of the crimping component 30 can be set to a shape with a larger contact area with the surface of the junction box 50 during rotation, and the effect of the device and the junction box 50 is better.

[0051] Further, in order to improve the convenience of connecting the counterweight block 60 with the connecting component 20, the above-mentioned terminal box counterweight block installation anti-falling device can also include a hanging component 40. The structure of the hanging component 40 in this embodiment can refer to Figure 2 , Figure 2 A schematic diagram of the structure of a suspension component in a junction box counterweight installation anti-falling device provided by an embodiment of the utility model. The suspension component 40 can be set as a slender rod with a diameter of 2 mm, and is connected to the connecting component 20 through a 1 mm steel shaft. A hole 41 for passing the steel shaft is correspondingly provided at the connection between the suspension component 40 and the connecting component 20. An annular steel ring 42 can be provided at the lower end of the suspension component 40. The annular steel ring 42 can be set to 10 mm for hanging the counterweight 60.

[0052] Furthermore, in order to ensure the regularity of the rotation of the connecting member 20, the articulator frame 10 may be provided with a limited guide groove;

[0053] The connecting component 20 is correspondingly arranged in the limiting guide groove so as to rotate in the limiting guide groove when an external force acts.

[0054] It should be noted that the articulator frame 10 of this embodiment is provided with a limiting guide groove for limiting the rotation of the connecting component 20, which can regulate the rotation process of the connecting component 20 and ensure that the connecting component 20 rotates in a specified direction. This embodiment does not limit the specific structure of the limiting guide groove, as long as it can limit the rotation process of the connecting component 20. The specific structure of the connecting component 20 in this embodiment can be referred to Figure 3 , Figure 3 A schematic diagram of the structure of a connecting component in a junction box counterweight installation anti-falling device provided by an embodiment of the utility model. The connecting component 20 can be set as a T-shaped structure, with the two ends of the horizontal structure 23 respectively connected to the crimping component 30, and a ball head 22 is set at the vertical structure 21, and a ball head installation groove for installing the ball head is correspondingly set on the articulator frame 10, and a ball head limiting guide groove is set outside the ball head installation groove to limit the rotation stroke of the connecting component 20.

[0055] Further, in order to improve the stability of the anti-dropping device for installing the counterweight block 60 of the junction box 50 and the engagement with the junction box 50, the crimping component 30 may include a plurality of crimping subcomponents;

[0056] When mounted on the junction box 50 , the plurality of crimping sub-components abut against the junction box 50 at a plurality of locations on the surface of the junction box 50 .

[0057] It should be noted that, in this embodiment, when the counterweight block 60 is connected to the second connection end and the connection component 20 is driven to rotate, multiple crimping sub-components form a tendency to move toward the inside of the junction box 50 at multiple positions on the second surface of the junction box 50. This embodiment does not limit the specific structure of the multiple crimping sub-components. For example, multiple crimping sub-components can be arranged along the symmetry center, or multiple crimping sub-components can be arranged in other ways. Accordingly, this embodiment does not limit the specific number of crimping sub-components. For example, the number of crimping sub-components can be set to two, or the number of crimping sub-components can also be set to three.

[0058] Furthermore, in order to reduce the manufacturing cost of the device, the plurality of crimping sub-components mentioned above may all be connected to the first connection end.

[0059] It should be noted that in this embodiment, multiple crimping sub-components are connected to the first connecting end, and only one hinge point needs to be set to enable the connecting component 20 to drive the crimping component 30 to rotate, which reduces the preparation cost of the crimping component 30 and improves the reliability of the device.

[0060] Furthermore, in order to increase the friction between the crimping component 30 and the junction box 50 when the crimping component 30 and the junction box 50 are squeezed, the crimping component 30 may include a horseshoe-shaped rubber crimping piece 31 .

[0061] It should be noted that the crimping component 30 provided in the present embodiment includes a horseshoe-shaped rubber crimping piece 31, which can increase the friction between the crimping component 30 and the junction box 50 through the rubber material, and at the same time utilize the horseshoe shape to increase the contact area between the crimping component 30 and the junction box 50, thereby improving the stability of the snap-fitting between the device and the junction box 50.

[0062] Further, in order to increase the service life of the anti-falling device for the junction box 50 counterweight block 60, reference may be made to Figure 4 , Figure 4 A schematic diagram of the structure of a protective isolation plate in a device for preventing a counterweight block from falling off provided in an embodiment of the utility model. A protective isolation plate 70 may also be included;

[0063] The articulator frame 10 includes a first sub-frame and a second sub-frame arranged on two surfaces corresponding to the junction box 50 and a connecting sub-frame connecting the first sub-frame and the second sub-frame;

[0064] The protective isolation plate 70 is connected to the first sub-frame or the second sub-frame through an isolation connection component to form a receiving cavity, and an opening is provided in the protective isolation plate 70;

[0065] The crimping component 30 passes through the opening and one end thereof extends into the accommodating cavity and is hinged to the first connecting end.

[0066] It should be noted that in this embodiment, the articulator frame 10 includes a first sub-frame and a second sub-frame arranged on two surfaces corresponding to the junction box 50, that is, the articulator frame is provided with corresponding sub-frames on both surfaces corresponding to the junction box 50, and a protective isolation plate 70 is provided on the side of the junction box 50 corresponding to the crimping component 30, and a receiving cavity is formed between the protective isolation plate 70 and the first sub-frame or the second sub-frame, and part of the connecting component 20, part of the crimping component 30, and the hinge point between the connecting component 20 and the crimping component 30 are arranged in the receiving cavity to protect the above structure. This embodiment does not limit the specific material of the above-mentioned isolation connection component, as long as the protection isolation plate 70 can be firmly connected to the articulator frame 10. In this embodiment, the protection isolation plate 70 can be provided with a mounting guide rod 71 connected to the isolation connection component, and a claw 72 connected to the outside can be provided at the edge of the protection isolation plate 70. In this embodiment, the side where the protection isolation plate 70 is provided is the same side where the crimping component 30 is provided.

[0067] Further, in order to ensure the functionality of the isolation connection plate, please refer to Figure 5 , Figure 5 The structural schematic diagram of another anti-falling device for mounting a counterweight block of a junction box provided by an embodiment of the utility model. The above-mentioned isolation connection component can be set as a spring part 14.

[0068] It should be noted that in this embodiment, the isolation connection component is set as a spring component 14, and when the counterweight 60 is not connected to the second connection end, the protective isolation plate 70 can be used to abut against the surface of the junction box 50 to connect the junction box counterweight installation anti-falling device to the junction box 50. At this time, the elastic force of the spring component 14 can ensure that there is a corresponding space between the protective isolation plate 70 and the articulator frame 10 part on the same side, avoiding damage to the structure between the protective isolation plate 70 and the articulator frame 10 part on the same side. In addition, it should be noted that in this embodiment, a ball head mounting base 13 can be set in the articulator frame 10, and a ball head mounting groove 11 for mounting a ball head set in the connection component 20 is provided in the ball head mounting base 13, and a limited position guide groove 12 is provided outside the ball head mounting groove 11.

[0069] The anti-falling device for installing the counterweight 60 of the junction box 50 provided by the embodiment of the utility model includes an articulator frame 10, a connecting component 20 and a crimping component 30. One end of the articulator frame 10 abuts against the first surface of the junction box 50. The connecting component 20 is connected to the articulator frame 10 to form a rotating pair, and the first connecting end of the connecting component 20 extends to the inner side of the articulator frame 10, and the second connecting end of the connecting component 20 extends to the outer side of the articulator frame 10. One end of the crimping component 30 is hinged to the first connecting end, and the other end of the crimping component 30 abuts against the second surface, so that when the counterweight 60 is connected at the second connecting end and the connecting component 20 is driven to rotate, the crimping component 30 is driven to rotate in the opposite direction of the connecting component 20. The first surface and the second surface are two surfaces formed in opposition to each other for the junction box 50. The utility model connects the connecting component 20 with the articulator frame 10 to form a rotating pair, and connects the two ends of the connecting component 20 to the crimping component 30 and the counterweight block 60 respectively. When the second connecting end is connected to the counterweight block, the connecting component 20 is driven to rotate, and the crimping component 30 has a tendency to rotate and move toward the surface of the junction box 50, so that it can abut against the surface of the junction box 50 by friction force to form a snap-fit ​​engagement.

[0070] In addition, the embodiment of the utility model can regulate the rotation process of the connecting component 20 and ensure that the connecting component 20 rotates in a specified direction by setting a limiting guide groove in the articulator frame 10 to limit the rotation of the connecting component 20; when the counterweight block 60 is connected to the second connecting end and drives the connecting component 20 to rotate, multiple crimping sub-components form a tendency to move toward the inside of the junction box 50 at multiple positions on the second surface of the junction box 50, thereby improving the stability of the anti-falling device for installing the junction box counterweight block and the clamping and biting of the junction box 50; connecting multiple crimping sub-components to the first connecting end increases the preparation cost of the crimping component 30 and improves the reliability of the device; setting the crimping part Part 30 includes a horseshoe-shaped rubber crimping part 31, which can improve the stability of the snap-fitting engagement between the device and the junction box 50; a protective isolation plate is correspondingly arranged on the surface of one side of the junction box 50, which can arrange part of the connecting component 20, part of the crimping component 30, and the hinge point between the connecting component 20 and the crimping component 30 in the accommodating cavity to form protection; the isolating connecting component is arranged as a spring component, which can be used to abut the surface of the junction box 50 by the protective isolation plate when the counterweight block 60 is not connected to the second connecting end, thereby ensuring that there is a corresponding space between the protective isolation plate and the part of the articulator frame 10 on the same side, thereby avoiding damage to the structure between the protective isolation plate and the part of the articulator frame 10 on the same side.

[0071] Embodiment 2:

[0072] The difference between the junction box counterweight installation anti-falling device provided in the embodiment of the utility model and embodiment 1 is that the articulator frame and the crimping component are correspondingly abutted against the upper surface and the lower surface of the junction box in the vertical direction.

[0073] It should be noted that in this embodiment, the articulator frame and the crimping component are correspondingly abutted against the upper surface and the lower surface of the junction box, that is, the first surface and the second surface are correspondingly set as the upper surface and the lower surface of the junction box, and the structure set on the upper surface of the junction box can use the support force of the upper surface of the junction box to improve the stability of the connection. It should be further noted that in this embodiment, one end of the articulator frame can be abutted against the lower surface of the junction box, and the crimping component can be correspondingly abutted against the upper surface of the junction box to ensure the stability of the connection between the above-mentioned connection component and the crimping component.

[0074] In a possible embodiment, the present embodiment may further provide a junction box counterweight installation anti-dropping device as described above corresponding to the side of the junction box, so as to increase the stability of the counterweight installation through the friction force formed with the side of the junction box. Specifically, a side connecting component, a side engaging portion frame abutting against the first side surface of the junction box, and a side crimping component abutting against the second side surface of the junction box may be provided;

[0075] The side occlusal frame is connected to the articulator frame, the side crimping component is connected to the articulator frame or the side occlusal frame to form a revolving pair, and the third connecting end of the connecting component extends to the inner side of the articulator frame or the side occlusal frame, and the fourth connecting end of the connecting component extends to the outer side of the articulator frame or the side occlusal frame;

[0076] One end of the side crimping component away from the second side surface of the junction box is hinged to the third connecting end, so that when the third connecting end is connected to the counterweight block and drives the side connecting component to rotate, the side crimping component is driven to rotate in the opposite direction of rotation to the side connecting component;

[0077] The first side surface and the second side surface are two side surfaces of the junction box that are aligned with each other.

[0078] It should be noted that in this embodiment, by respectively arranging a side engaging portion frame and a side crimping component on the two side surfaces of the junction box, the stability of the connection between the device and the junction box can be further improved, and the risk of the counterweight falling off can be further reduced.

[0079] The anti-falling device for installing the junction box counterweight provided in the embodiment of the utility model can make the structure arranged on the upper surface of the junction box use the supporting force of the upper surface of the junction box to improve the stability of the connection by making the articulator frame and the crimping component correspondingly abut against the upper surface and the lower surface of the junction box.

[0080] Embodiment 3:

[0081] The difference between the junction box counterweight installation anti-falling device provided in the embodiment of the utility model and the embodiment 1 is that it also includes a sleeve component connected to the articulator frame 10; the crimping component 30 passes through the sleeve component and is connected to the first connecting end.

[0082] It should be noted that in this embodiment, a sleeve component is provided, and a crimping component 30 is provided which is connected to the first connecting end through the sleeve component. The sleeve component can be used as a supporting point to support the crimping component 30, thereby improving the stability of the structure and preventing the torque generated when installing the counterweight from acting entirely on the crimping component 30, thereby increasing the service life of the crimping component 30.

[0083] Further, in order to improve the adaptability of the device, you can refer to Figure 6 , Figure 6 A partial structural diagram of a movable sleeve rod provided in a junction box counterweight installation anti-falling device provided in an embodiment of the utility model. The sleeve component can be provided as a movable sleeve rod 81, and the rotation axis of the movable sleeve rod 81 is parallel to the rotation axis of the connecting component;

[0084] The crimping component 30 includes an L-shaped connecting rod, which passes through the movable sleeve rod 81 and is connected to the first connecting end.

[0085] It should be noted that in this embodiment, by providing a movable sleeve rod 81 parallel to the rotation axis of the connecting component, and providing the crimping component 30 to be connected to the first connection end through the movable sleeve rod 81, the movable sleeve rod 81 can be used to support the crimping component 30, thereby improving the structural strength and stability of the crimping component 30, and the movable sleeve rod 81 can be rotatable to ensure the movable space of the crimping component 30, thereby improving the adaptability of the device. In this embodiment, when providing the movable sleeve rod 81 sleeved on the outside of the crimping component 30, it is necessary to connect the movable sleeve rod 81 to the articulator frame 10 using a mounting bracket.

[0086] The anti-drop-off device for installing the counterweight block of the junction box provided by the embodiment of the utility model is provided with a sleeve component, and the crimping component 30 is provided to be connected to the first connection end through the sleeve component, so that the sleeve component can be used as a support point to support the crimping component 30, thereby improving the stability of the structure, avoiding that the torque generated when installing the counterweight block is fully applied to the crimping component 30, and thus improving the service life of the crimping component 30. In addition, the embodiment of the utility model improves the flexibility and adaptability of the device by providing a movable sleeve rod 81 parallel to the rotation axis of the connecting component, and providing the crimping component 30 to be connected to the first connection end through the movable sleeve rod 81.

[0087] The anti-falling device for installing the counterweight block of the junction box provided by the utility model may specifically include the following structures:

[0088] Articulator frame, connecting parts, crimping parts and hanging parts; the crimping parts are horseshoe-shaped rubber crimping parts;

[0089] The occlusal end frame at one end of the occlusal frame abuts against the first surface of the junction box;

[0090] The connecting component is connected to the articulator frame to form a rotating pair, and the first connecting end of the connecting component extends to the inner side of the articulator frame, and the second connecting end of the connecting component extends to the outer side of the articulator frame; a limit guide groove is provided at the connection between the articulator frame and the connecting component, and the connecting component is correspondingly arranged in the limit guide groove so as to rotate in the limit guide groove when an external force acts;

[0091] One end of the crimping component is hinged to the first connection end, the other end of the crimping component is in contact with the second surface, and the hanging component is connected to the second connection end, so that when the hanging component is connected to the counterweight block and drives the connection component to rotate, the crimping component is also driven to rotate in the opposite direction of the connection component; the first surface and the second surface are two surfaces that form a counterposition of the junction box;

[0092] The articulator frame and the crimping component are correspondingly abutted against the upper surface and the lower surface of the junction box in the vertical direction;

[0093] The crimping component includes a plurality of crimping sub-components. When installed to the junction box, the plurality of crimping sub-components abut against the junction box at a plurality of positions on the surface of the junction box, and the plurality of crimping sub-components are all connected to the first connection end.

[0094] It also includes a movable sleeve rod connected to the articulator frame, the rotation axis of the movable sleeve rod is parallel to the rotation axis of the connecting component, and the crimping component includes an L-shaped connecting rod, which passes through the movable sleeve rod and is connected to the first connecting end;

[0095] It also includes a protective isolation plate, and the articulator frame includes a first sub-frame and a second sub-frame arranged on two surfaces corresponding to the junction box, and a connecting sub-frame connecting the first sub-frame and the second sub-frame; the protective isolation plate is connected to the first sub-frame or the second sub-frame through an isolation connecting component to form a accommodating cavity, and an opening is provided in the protective isolation plate, the crimping component passes through the opening and one end of the crimping component extends into the accommodating cavity and is hinged to the first connecting end; the isolation connecting component is a spring component.

[0096] When the hanging component is connected to the counterweight, the gravity of the counterweight causes the connecting component to obtain a downward pulling force, which causes the connecting component to rotate, and the connecting component drives the crimping component to rotate in the opposite direction. Since the crimping component is constrained in the movable sleeve rod, the movable sleeve rod rotates, and the crimping component slides in the movable sleeve rod. Finally, the crimping component will be displaced downward, thereby generating a greater friction force on the surface of the junction box, and finally the counterweight and the device will not fall off the junction box.
