[0003] In order to facilitate use, storage and transportation, the existing special-shaped photovoltaic welding ribbons are wound on a wire drum, and wire reels for limiting are set at both ends of the wire drum. If the special-shaped photovoltaic welding ribbon needs to be used, the wire drum needs to be put on a rod-type bracket, and then the user pulls the special-shaped photovoltaic welding ribbon, and the pulled special-shaped photovoltaic welding ribbon will drive the wire drum to rotate on the rod-type bracket until the special-shaped photovoltaic welding ribbon is used up. Since the rod-type bracket is required for cooperation, the user needs to carry a matching bracket when carrying the special-shaped photovoltaic welding ribbon, which not only takes up more storage space, but also increases the weight of the carrying tool. Utility Model Content

[0004] The purpose of the utility model is to provide a special-shaped photovoltaic welding strip to solve the problems raised in the above background technology:

[0005] The existing special-shaped photovoltaic welding ribbon requires the wire reel to be put on a rod-shaped bracket, and then the user pulls the special-shaped photovoltaic welding ribbon, and the pulled special-shaped photovoltaic welding ribbon will drive the wire reel to rotate on the rod-shaped bracket until the special-shaped photovoltaic welding ribbon is used up. Since the rod-shaped bracket is required for cooperation, the user needs to carry a matching bracket when carrying the special-shaped photovoltaic welding ribbon, which not only takes up more storage space, but also increases the weight of the carrying tool.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A special-shaped photovoltaic welding strip comprises a wire drum, a welding strip body is wound on the outside of the wire drum, a wire drum is sleeved on the outside of the wire drum and on the corresponding two sides of the welding strip body, the wire drum is rotatably connected to the wire drum, the inside of the wire drum is rotatably connected to a rotating shaft, both ends of the rotating shaft are fixedly connected to a support plate, and a storage groove is opened on the outside of the wire drum, and the storage groove is used in conjunction with the support plate.

[0008] Preferably, a first slide groove is opened inside the wire drum, and the inside of the first slide groove is slidably connected to a limit rod, a first spring is arranged between the limit rod and the first slide groove, one end of the first spring is fixedly connected to the wire drum, and the other end of the first spring is fixedly connected to the limit rod.

[0012] Preferably, the cross-sections of the second sliding groove and the blocking block are both rectangular structures.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1) When the special-shaped photovoltaic welding tape is in use, the support plate is rotated out to a position where it is perpendicular to the wire reel. At this time, the wire drum is supported by the support plate in cooperation with the wire reel. Since the wire reel and the wire reel are rotatably connected, the welding tape body can be used normally when being pulled. The support plate acts as a support frame, and there is no need to carry and use other support frames separately, thereby reducing the weight of the tools that the user needs to carry.

[0020] Example 1

[0021] The existing special-shaped photovoltaic welding ribbon requires the wire reel to be put on a rod-shaped bracket, and then the user pulls the special-shaped photovoltaic welding ribbon, and the pulled special-shaped photovoltaic welding ribbon will drive the wire reel to rotate on the rod-shaped bracket until the special-shaped photovoltaic welding ribbon is used up. Since the rod-shaped bracket is required for cooperation, the user needs to carry a matching bracket when carrying the special-shaped photovoltaic welding ribbon, which not only takes up more storage space, but also increases the weight of the carrying tool.

[0022] See also Figures 1 to 3 A special-shaped photovoltaic welding tape comprises a wire drum 1, a welding tape body 2 is wound on the outside of the wire drum 1, and a wire drum 3 is sleeved on the corresponding two side edges of the welding tape body 2 on the outside of the wire drum 1. The welding tape body 2 is wound around the outside of the wire drum 1 in circles, and the wire drum 3 is arranged on both sides of the entire welding tape body 2 after winding, so as to block and limit the welding tape body 2 during the pulling process; the wire drum 3 is rotatably connected to the wire drum 1, and the inside of the wire drum 3 is rotatably connected to a rotating shaft 4, and both ends of the rotating shaft 4 are fixedly connected to support plates 5, and a storage groove 6 is opened on the outside of the wire drum 3, and the storage groove 6 is used in conjunction with the support plate 5. When the welding tape body 2 is not needed, the support plates 5 arranged at both ends of the rotating shaft 4 can be stored in the storage groove 6, which is smaller in size and does not take up too much space.

[0023] A first slide groove 7 is provided inside the wire drum 3, and a limit rod 8 is slidably connected inside the first slide groove 7. A first spring 9 is provided between the limit rod 8 and the first slide groove 7, and one end of the first spring 9 is fixedly connected to the wire drum 3, and the other end of the first spring 9 is fixedly connected to the limit rod 8. When the support plate 5 is received in the receiving groove 6, the elastic force of the first spring 9 will drive the limit rod 8 to press the support plate 5, so as to prevent the support plate 5 received in the receiving groove 6 from rotating out by itself due to the lack of limit.

[0024] A limiting groove 10 is provided at one end of the support plate 5 away from the rotating shaft 4, and the limiting groove 10 is used in conjunction with the limiting rod 8. The end of the limiting rod 8 away from the first spring 9 is spherical to prevent the limiting rod 8 from hindering the complete storage of the support plate 5 during the storage process. Correspondingly, the limiting groove 10 is also spherical. After the support plate 5 is completely stored in the storage groove 6, the limiting rod 8 engages with the limiting groove 10 to improve the limiting capacity.

[0025] The support plate 5 and the storage groove 6 are both arc-shaped structures. The arc-shaped storage groove 6 is adapted to the arc-shaped support plate 5. When the support plate 5 is completely stored in the storage groove 6, the wire drum 3 as a whole is a complete circular structure, which is more regular.

[0026] The use steps of the utility model are as follows: when using the special-shaped photovoltaic welding strip, the support plate 5 on each wire drum 3 is rotated outward in turn, so that the support plate 5 is rotated out of the storage groove 6 on the wire drum 3, until the support plate 5 is rotated to a position perpendicular to the wire drum 3. At this time, the whole can be placed in a corresponding location, and the wire drum 1 is supported by the support plate 5 in cooperation with the wire drum 3. Since the wire drum 1 and the wire drum 3 are rotatably connected, the welding strip body 2 can be used normally when being pulled. The support plate 5 acts as a support frame, and there is no need to carry and use other support frames separately. After use, the support plate 5 is rotated in the opposite direction until it is stored in the storage groove 6 again.

[0027] Example 2

[0028] When the welding strip body 2 is pulled, if the wire drum 1 is not limited, the wire drum 1 may be reversed after the welding strip body 2 is pulled, causing the pulled welding strip body 2 to be pulled in the opposite direction, thereby affecting the user's use of the welding strip body 2.

[0029] See also Figure 3 The difference between the combined implementation and the base is that a second slide groove 11 is provided inside the wire drum 3, and a block 12 is slidably connected inside the second slide groove 11, and a second spring 13 is arranged between the block 12 and the second slide groove 11. A slot 14 is provided on the outside of the wire drum 1, and the slot 14 is used in conjunction with the block 12. Under the elastic force of the second spring 13, the block 12 and the slot 14 remain engaged, and the rotating wire drum 1 in the wire drum 3 is limited by the block 12 and the slot 14 to prevent reversal.

[0030] The cross-sections of the second slide groove 11 and the block 12 are both rectangular structures. The second slide groove 11 with a rectangular cross-section serves to limit the block 12 with a rectangular cross-section, thereby preventing the block 12 from rotating laterally in the second slide groove 11 and preventing the block 12 from being misaligned with the slot 14.

[0031] The use steps of the utility model are as follows: when the special-shaped photovoltaic welding tape is in use, when the user pulls the welding tape body 2 wound on the bobbin 1, the wire drum 3 inside the wire drum 1 will be driven to rotate. Since the side of the clamping block 12 arranged inside the wire drum 3 is a trapezoidal structure, its inclined surface faces the opposite direction of the pulling of the welding tape body 2, when the welding tape body 2 is pulled, the wire drum 1 can rotate normally, but when the wire drum 1 needs to be reversed, the clamping block 12 and the engaged clamping groove 14 will limit the wire drum 1, making it impossible for the wire drum 1 to be reversed, thereby preventing the already pulled-out welding tape body 2 from being pulled in the opposite direction.
