Joint box dismounting tool

Abstract

This utility model provides a junction box disassembly fixture. The junction box disassembly fixture includes a handle, a rotating support module, a ratchet, and a pawl. One end of the handle has a plug-in part and a mounting part arranged opposite each other. The rotating support module includes a connecting shaft and a support body. The ratchet is mounted on the connecting shaft. The pawl is located on one side of the ratchet and is rotatably mounted on the mounting part. When using the junction box disassembly fixture of this application, the plug-in part is inserted into the gap between the ratchet and the pawl to lock the junction box cover, and then the support body is driven to abut against the top surface of the junction box cover. At this time, because the pawl and the ratchet cooperate to restrict the rotation of the support body away from the plug-in part, the junction box disassembly fixture forms a lever structure. Rotating the handle makes the latch between the junction box body and the junction box cover open, so that the junction box cover can be removed from the junction box body. The operation time is short and the safety is high, which helps to speed up the production cycle and improve the rework efficiency of the junction box.

Description

Technical Field

[0001] This utility model relates to the field of junction box disassembly, and in particular to a junction box disassembly tool. Background Technology

[0002] Junction boxes play a crucial role as the output channel for internal current in photovoltaic modules. During the production of photovoltaic modules, issues such as poor welding of the junction boxes necessitate rework, which requires removing the junction box cover, removing the internal silicone sealant, and then proceeding with the repair. However, due to the structural design of existing junction boxes, the junction box cover is difficult to remove. Utility Model Content

[0003] Therefore, it is necessary to provide a junction box disassembly tool to address the problem that the junction box cover is not easy to remove in the existing technology.

[0004] The technical solution is as follows:

[0005] On the one hand, a junction box disassembly tooling is provided, including:

[0006] The handle has a plug-in part and a mounting part arranged opposite to each other at one end. The plug-in part is used to insert into the gap between the junction box cover and the junction box body.

[0007] A rotating support module, comprising a connecting shaft rotatably mounted on the mounting portion and a support body connected to the connecting shaft, the support body being used to abut against the top surface of the junction box cover;

[0008] A ratchet and a pawl, wherein the ratchet is mounted on the connecting shaft, the pawl is located on one side of the ratchet and is rotatably mounted on the mounting portion, and the pawl is configured to restrict the support body from rotating in a direction away from the insertion portion when the ratchet and the pawl are engaged.

[0009] In the junction box disassembly fixture described in the above embodiment, during use, firstly, the pawl is driven to rotate, causing the ratchet to separate from the pawl. Then, the support body is driven to rotate away from the plug-in portion to the side of the mounting portion away from the plug-in portion, driving the pawl to reset and re-engage with the ratchet. Next, the plug-in portion is inserted into the gap between the ratchet and the pawl to lock the junction box cover. The support body is pressed, causing it to rotate towards the plug-in portion until the top surface of the support body abuts against the junction box cover. At this point, the engagement of the pawl and ratchet restricts the rotation of the support body away from the plug-in portion, forming a lever structure. Finally, the handle is turned, causing the latch of the junction box cover to slightly lift. After the latch between the junction box body and the junction box cover is pried open, it is lifted upwards to remove the junction box cover from the junction box body. This operation is quick and safe, which helps to speed up the production cycle and improve the rework efficiency of the junction boxes.

[0010] The technical solution will be further explained below:

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, a junction box disassembly fixture 10 is provided, including a handle 100, a rotating support module 200, a ratchet 300, and a pawl 400. One end of the handle 100 has a plug-in portion 110 and a mounting portion 120 disposed opposite to each other. The plug-in portion 110 is used to insert into the gap between the junction box cover 21 and the junction box body 22. The rotating support module 200 includes a connecting shaft rotatably mounted on the mounting portion 120 and a support body connected to the connecting shaft. The support body is used to abut against the top surface of the junction box cover 21. The ratchet 300 is mounted on the connecting shaft. The pawl 400 is located on one side of the ratchet 300 and is rotatably mounted on the mounting portion 120. The pawl 400 is configured to restrict the rotation of the support body away from the plug-in portion 110 when the ratchet 300 is engaged with the pawl 400.

[0031] In the above embodiment, the junction box disassembly fixture 10 is used as follows: First, the pawl 400 is driven to rotate, causing the ratchet 300 to separate from the pawl 400. Then, the support body is driven to rotate in a direction away from the plug-in portion 110 until the mounting portion 120 is on the side away from the plug-in portion 110. The pawl 400 is then driven to reset, and the pawl 400 and ratchet 300 re-engage. Next, the plug-in portion 110 is inserted into the gap between the ratchet 300 and the pawl 400 to lock the junction box cover 21. The support body is then pressed, causing it to rotate towards the plug-in portion 110 until the support body abuts against the top surface of the junction box cover 21. At this point, the engagement of the pawl 400 and ratchet 300 restricts the rotation of the support body away from the plug-in portion 110, thus forming a lever structure for the junction box disassembly fixture 10. Finally, turn the handle 100 so that the latch of the junction box cover 21 is slightly lifted. After the latch between the junction box body 22 and the junction box cover 21 is pried open, lift it upward to remove the junction box cover 21 from the junction box body 22. The operation is quick and safe, which helps to speed up the production cycle and improve the repair efficiency of the junction box.

[0032] It should be noted that when the ratchet 300 is engaged with the pawl 400, the support body can rotate in the direction close to the insertion part 110, but cannot rotate in the direction away from the insertion part 110. When the ratchet 300 is disengaged from the pawl 400, the support body can rotate in the direction close to or away from the insertion part 110.

[0033] like Figure 3 As shown, in this specific embodiment, when the ratchet 300 and the pawl 400 are engaged, the support body can rotate counterclockwise, but cannot rotate clockwise.

[0034] Specifically, in this embodiment, the handle 100 can be made of stainless steel, hollow or solid aluminum alloy, or a composite material. Both the insertion portion 110 and the mounting portion 120 are integrally formed with the handle 100. The length of the handle 100 can be set to 120mm to 150mm, and the width of the handle 100 can be set to 20mm to 30mm. The handle 100 can act as an extension lever arm, reducing the force required for disassembly and providing a mounting base for other parts.

[0035] Specifically, in this embodiment, the ratchet 300 can be made of stainless steel or aluminum alloy. The ratchet 300 is fixedly mounted on the connecting shaft and is coaxial with it. The outer diameter of the ratchet 300 can be 8mm to 10mm, and the number of teeth can be 18 to 22. The pawl 400 can be made of stainless steel or aluminum alloy. The width of the pawl 400 can be 5mm to 9mm. The ratchet 300 and pawl 400 cooperate to ensure unidirectional rotation of the rotating support module 200 and to form a lever with the plug-in portion 110 when the junction box cover 21 is removed.

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, the junction box disassembly fixture 10 further includes an elastic element 500. The elastic element 500 is mounted on the mounting portion 120 and contacts the pawl 400. The elastic element 500 is configured to apply an elastic restoring force to the pawl 400 to engage with the ratchet 300 when the pawl 400 is separated from the ratchet 300. Thus, under the action of the elastic element 500, the pawl 400 has a tendency to rotate toward the ratchet 300, ensuring that the pawl 400 can remain engaged with the ratchet 300 when no external force is applied, and can promptly return to engagement with the ratchet 300 when the applied external force is removed or when the support body rotates in a direction close to the plug portion 110, thereby improving the reliability of the junction box disassembly fixture 10.

[0037] The elastic element 500 can be configured as a spring, elastic pad, elastic strip, or other elastic structure. Specifically, in this embodiment, the elastic element 500 is configured as a spring sheet. The spring sheet can be made of conventional spring steel. The pawl 400 is located above the ratchet 300, and the spring sheet is located above the pawl 400. The width of the spring sheet can be 5mm to 9mm.

[0038] like Figure 5 As shown, optionally, the two ends of the pawl 400 are respectively configured as an engaging end 410 and a driving end 420. The engaging end 410 contacts the elastic member 500 and engages with the ratchet 300. The driving end 420 is used to receive the driving force that separates the engaging end 410 from the ratchet 300. Thus, by applying a driving force to the driving end 420, the engaging end 410 can be correspondingly separated from the ratchet 300, and the elastic member 500 is compressed. When the driving force is removed to release the driving end 420, the elastic member 500 resets and drives the engaging end 410 to rotate in a direction close to the ratchet 300, so that the engaging end 410 automatically engages with the ratchet 300. This operation is simple and convenient, improving the practicality of the junction box disassembly fixture 10.

[0039] like Figure 3 and Figure 5 As shown, in one embodiment, the mounting portion 120 is provided with a mounting cavity 121. The ratchet 300, pawl 400, and elastic element 500 are all mounted within the mounting cavity 121. In this way, the ratchet 300, pawl 400, and elastic element 500 are all hidden within the mounting cavity 121, preventing external objects from interfering with any of the ratchet 300, pawl 400, and elastic element 500, thereby improving the reliability of the junction box disassembly fixture 10.

[0040] like Figure 3 and Figure 5As shown, optionally, the mounting portion 120 has a mounting hole on the side away from the plug-in portion 110. The junction box disassembly fixture 10 also includes a button 600, which is mounted at the mounting hole and moves and engages with the mounting hole along the axial direction of the mounting hole. The button 600 is connected to the drive end 420. Thus, when the button 600 is pressed, the button 600 presses down on the drive end 420, and the engaging end 410 rotates in a direction away from the ratchet 300 and separates from the ratchet 300. At this time, the elastic element 500 is compressed, and the support body can rotate in a direction away from the plug-in portion 110. This avoids interference between the support body and the junction box cover 21 during the insertion of the plug-in portion 110 into the gap between the junction box cover 21 and the junction box body 22, ensuring that the plug-in portion 110 can be smoothly inserted into the gap between the junction box cover 21 and the junction box body 22, and improving the practicality of the junction box disassembly fixture 10. When the support body rotates away from the plug-in portion 110 to the side of the mounting portion 120 away from the plug-in portion 110, the button 600 is released, the elastic element 500 presses against the engagement end 410 and drives the engagement end 410 to reset, so that the engagement end 410 can re-engage with the ratchet 300 and remain there, improving the reliability of the junction box disassembly fixture 10.

[0041] Specifically, in this embodiment, the button 600 can be made of stainless steel, hollow or solid aluminum alloy, or a composite material. The button 600 is located above the drive end 420 and is in contact with the drive end 420.

[0042] like Figure 3 and Figure 5 As shown, optionally, the mounting part 120 is further provided with a first mounting through hole and a second mounting through hole, both of which communicate with the mounting cavity 121. The first mounting through hole and the second mounting through hole are spaced apart and both extend along the axial direction of the connecting shaft. The connecting shaft passes through the first mounting through hole. The junction box disassembly fixture 10 also includes a rotating shaft 700, which passes through the second mounting through hole. The pawl 400 is mounted on the rotating shaft 700. In this way, the ratchet 300 is rotatably mounted in the mounting cavity 121 via the connecting shaft, and the pawl 400 is rotatably mounted in the mounting cavity 121 via the rotating shaft 700, improving the ease of assembly of the junction box disassembly fixture 10.

[0043] The shape and size of the first mounting through hole, the second mounting through hole, and the mounting hole can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the cross-sections of both the first and second mounting through holes are circular. The diameter of the first mounting through hole matches the diameter of the connecting shaft and is set to 5mm to 7mm. The diameter of the second mounting through hole matches the diameter of the rotating shaft 700 and is set to 1mm to 3mm. The cross-section of the mounting hole can be rectangular. The size of the mounting hole matches the size of the button 600. The cross-sectional length of the mounting hole can be set to 5mm to 9mm, and the cross-sectional width of the mounting hole can be set to 5mm to 9mm.

[0044] like Figure 1 As shown, in one embodiment, the mounting portion 120 is provided with a first mounting through hole for the connecting shaft to pass through. The support body also includes a first connector 210, a second connector 220, and a support member 230. The first connector 210 and the second connector 220 are spaced apart and disposed on opposite sides of the mounting portion 120. One end of the first connector 210 and one end of the second connector 220 are respectively fixedly connected to both ends of the connecting shaft. The other end of the first connector 210 and the other end of the second connector 220 are respectively fixedly connected to both ends of the support member 230. The support member 230 is used to abut against the top surface of the junction box cover 21. Thus, the connecting shaft, the first connecting member 210, the second connecting member 220, and the support member 230 form a clearance space to avoid the mounting part 120, ensuring that the support body will not interfere with the mounting part 120. At the same time, the first connecting member 210 and the second connecting member 220 press against the two ends of the support member 230 respectively, so that the force distribution on the support member 230 is uniform, ensuring that the support member 230 can stably and reliably resist and support the junction box cover 21, thereby improving the reliability of the junction box disassembly fixture 10.

[0045] In this specific embodiment, both the first connector 210 and the second connector 220 are rods, and the support 230 is a plate. The connecting shaft, the first connector 210, the second connector 220, and the support 230 can all be made of stainless steel, hollow or solid aluminum alloy, or composite materials.

[0046] like Figure 1 As shown, optionally, the support body also includes a soft rubber pad 240. The soft rubber pad 240 is installed on the support member 230 at a position where it abuts against the junction box cover 21. Thus, during disassembly, the soft rubber pad 240 is located between the support member 230 and the junction box cover 21 to prevent the support member 230 from scratching the junction box cover 21 and to improve the reliability of the junction box disassembly fixture 10.

[0047] Specifically, in this embodiment, the length of the soft rubber pad 240 can be set to 30mm to 40mm, and the width of the soft rubber pad 240 can be set to 6mm to 10mm.

[0048] like Figure 2 and Figure 3 As shown, in one embodiment, the plug-in portion 110 includes a flange 111 extending along the axial direction of the handle 100 and a plug-in tooth 112. The plug-in tooth 112 is disposed on the side of the flange 111 near the mounting portion 120 and away from the handle 100. The plug-in tooth 112 is used to insert into the gap between the junction box cover 21 and the junction box body 22. In this way, the flange 111 and the plug-in tooth 112 cooperate to form a hook structure, which can lock the junction box cover 21, improving the practicality of the junction box disassembly fixture 10.

[0049] Specifically, in this embodiment, the flange 111 is along the axial direction of the handle 100 (e.g., Figure 3 The length of the flange 111 (in the direction shown by B) is greater than the thickness of the edge of the junction box cover 21 to ensure that the insertion teeth 112 on the flange 111 can be inserted into the gap between the junction box cover 21 and the junction box body 22. The length of the insertion teeth 112 can be set to 10mm to 12mm, and the height of the insertion teeth 112 can be set to 1mm to 2mm.

[0050] like Figure 2 and Figure 3 As shown, optionally, the side of the flange 111 away from the handle 100 and the side of the insertion tooth 112 away from the handle 100 are located in the same plane and are both used to fit against the outer wall of the junction box body 22. The insertion tooth 112 is inclined on the side near the handle 100. The width of the insertion tooth 112 gradually increases along the direction near the flange 111. In this way, the outer wall of the junction box body 22 can position the insertion part 110, and the inclined arrangement of the insertion tooth 112 on the side near the handle 100 can guide it, ensuring that the insertion tooth 112 can be smoothly inserted into the gap between the junction box cover 21 and the junction box body 22, improving the practicality of the junction box disassembly fixture 10.
