The description states that "The present utility model discloses a solar photovoltaic harness that is easy to connect, belonging to the technical field of solar photovoltaic harnesses. The present utility model includes a photovoltaic harness body, and adapter plugs are fixedly connected to the left and right ends of the photovoltaic harness body. Two devices are connected through the adapter plugs at the left and right ends of the photovoltaic harness body; the photovoltaic harness body is further provided with a regulating mechanism installed in the middle part, and the use length of the photovoltaic harness body can be adjusted by the regulating mechanism to avoid entanglement between adjacent photovoltaic harness bodies; the side of the adapter plug is provided with an adsorption connection mechanism, which is stably adsorbed on the connection device through the adsorption connection mechanism. This solar photovoltaic harness that is easy to connect can facilitate the connection of the harness during use, and can also reasonably regulate the use length of the harness according to actual use needs to avoid entanglement between adjacent harness bodies due to long harnesses."

[0004] The existing solar photovoltaic wiring harness can reasonably adjust the length of the wiring harness according to actual usage needs to avoid the interweaving and entanglement between adjacent wiring harnesses due to long wiring harnesses. However, after the length of the wiring harness is adjusted, it is not convenient to limit and fix the length of the wiring harness, which causes the wiring harness to easily shrink into the receiving block, making the photovoltaic wiring harness body easily loose inside the receiving block, reducing practicality. Utility Model Content

[0005] The purpose of the present utility model is to solve the problem in the prior art that after the length of the wiring harness is adjusted, it is inconvenient to limit and fix the length of the wiring harness, which causes the wiring harness to easily shrink into the accommodating block, making the photovoltaic wiring harness body easily loose inside the accommodating block, and a photovoltaic wiring harness connection structure is proposed.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a photovoltaic wiring harness connection structure, including a containing shell, a first roller is rotatably connected in the containing shell, an adjustment mechanism is provided at the inner top of the containing shell, a fixed plate is provided at the bottom of the adjustment mechanism, a second roller is rotatably connected to one side of the fixed plate, a photovoltaic wiring harness body is provided on the outer surfaces of the first roller and the second roller, a first fixed shell is fixedly connected to one side of the containing shell, a first limiting groove is provided at the bottom of the first fixed shell, a bidirectional threaded rod is rotatably connected in the first fixed shell, a movable plate is sleeved on the outer surface of the bidirectional threaded rod, the movable plate is movable through the first limiting groove, and a splint is fixedly connected to one side of the movable plate.

[0007] Preferably, the adjustment mechanism includes a second fixing shell, and the second fixing shell is connected to the inner top of the accommodating shell.

[0008] Preferably, a second limiting groove is provided on one side of the second fixing shell, and a one-way threaded rod is rotatably connected inside the second fixing shell.

[0009] Preferably, a movable frame is sleeved on the outer surface of the one-way threaded rod, and the movable frame movably passes through the second limiting groove.

[0010] Preferably, a movable plate is fixedly connected to the bottom of the movable frame, and the fixed plate is fixedly connected to the bottom of the movable plate.

[0011] Preferably, the smooth end of the one-way threaded rod movably passes through the second fixed shell, and the smooth end of the one-way threaded rod is fixedly mounted with a first rotating cap.

[0012] Preferably, the smooth end of the bidirectional threaded rod movably passes through the first fixed shell, and the smooth end of the bidirectional threaded rod is fixedly mounted with a second rotating cap.

[0013] Preferably, both ends of the photovoltaic wiring harness body are movably inserted into the accommodating shell, and both ends of the photovoltaic wiring harness body are fixedly connected with adapter plugs.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. In the utility model, after adjusting the length of the photovoltaic harness body according to actual needs, the bidirectional threaded rod is rotated. Since the first limiting groove limits the movable plate, the bidirectional threaded rod drives the two movable plates to move relative to each other, and the two movable plates drive the two clamping plates to move relative to each other, thereby facilitating the clamping and fixing of the photovoltaic harness body, avoiding the photovoltaic harness body from shrinking into the containing shell, causing the photovoltaic harness body to become loose in the containing shell, and improving stability during use.

When the movable frame drives the second roller to move upward, it can conveniently increase the tensioning force of the photovoltaic harness body, and pull the photovoltaic harness body toward the inside of the accommodating shell, so as to facilitate reducing the use length of the photovoltaic harness body. When the movable frame drives the second roller to move downward, it can reduce the tensioning force of the photovoltaic harness body in the accommodating shell, and at this time, the photovoltaic harness body is pulled toward the outside of the accommodating shell, so as to facilitate increasing the use length of the photovoltaic harness body, and conveniently adjust the length of the photovoltaic harness body according to actual needs, so as to facilitate the connection of the photovoltaic harness body.

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: Figure 1 - Figure 5 As shown, the utility model provides a photovoltaic wiring harness connection structure, including a containing shell 1, a first roller 2 is rotatably connected in the containing shell 1, an adjustment mechanism 3 is provided on the inner top of the containing shell 1, a fixed plate 4 is provided on the bottom of the adjustment mechanism 3, a second roller 5 is rotatably connected to one side of the fixed plate 4, a photovoltaic wiring harness body 6 is provided on the outer surfaces of the first roller 2 and the second roller 5, both ends of the photovoltaic wiring harness body 6 are movably passed through the containing shell 1, both ends of the photovoltaic wiring harness body 6 are fixedly connected to an adapter plug 7, a first fixed shell 8 is fixedly connected to one side of the containing shell 1, a first limiting groove 9 is provided at the bottom of the first fixed shell 8, a bidirectional threaded rod 10 is rotatably connected in the first fixed shell 8, a movable plate 11 is sleeved on the outer surface of the bidirectional threaded rod 10, the movable plate 11 is movably passed through the first limiting groove 9, and a clamping plate 12 is fixedly connected to one side of the movable plate 11.

[0026] The effect achieved by the entire embodiment 1 is that after adjusting the length of the photovoltaic harness body 6 according to actual needs, the bidirectional threaded rod 10 is rotated. Since the first limiting groove 9 limits the movable plate 11, the bidirectional threaded rod 10 drives the two movable plates 11 to move relative to each other, and the two movable plates 11 drive the two clamping plates 12 to move relative to each other, thereby facilitating the clamping and fixing of the photovoltaic harness body 6, avoiding the photovoltaic harness body 6 from shrinking into the containing shell 1, causing the photovoltaic harness body 6 to become loose in the containing shell 1, and improving the stability during use.

[0027] Example 2: Figure 1 - Figure 5 As shown, the adjustment mechanism 3 includes a second fixed shell 301, which is connected to the inner top of the accommodating shell 1, and a second limiting groove 302 is opened on one side of the second fixed shell 301. A one-way threaded rod 303 is rotatably connected to the second fixed shell 301, and the outer surface of the one-way threaded rod 303 is sleeved with a movable frame 304, and the movable frame 304 movably passes through the second limiting groove 302. The bottom of the movable frame 304 is fixedly connected to a movable plate 305, and the fixed plate 4 is fixedly connected to the bottom of the movable plate 305. The smooth end of the one-way threaded rod 303 movably passes through the second fixed shell 301, and the smooth end of the one-way threaded rod 303 is fixedly installed with a first rotating cap 306. The smooth end of the bidirectional threaded rod 10 movably passes through the first fixed shell 8, and the smooth end of the bidirectional threaded rod 10 is fixedly installed with a second rotating cap 13. The two ends of the photovoltaic harness body 6 movably pass through the accommodating shell 1, and both ends of the photovoltaic harness body 6 are fixedly connected to the adapter plug 7.

[0028] The effect achieved by the entire embodiment 2 is that, by means of the provided adjustment mechanism 3, the first rotating cap 306 is rotated, so that the first rotating cap 306 drives the one-way threaded rod 303 to rotate, and since the second limiting groove 302 limits the movable frame 304, the one-way threaded rod 303 drives the movable frame 304 to move upward or downward, thereby causing the movable frame 304 to drive the second roller 5 to move upward or downward. When the one-way threaded rod 303 drives the movable frame 304 to move upward, the movable frame 304 drives the second roller 5 to move upward, which can conveniently increase the tensioning force of the photovoltaic harness body 6, pull the photovoltaic harness body 6 toward the inside of the accommodating shell 1, and facilitate reducing the use of the photovoltaic harness body 6. Length, when the one-way threaded rod 303 drives the movable frame 304 to move downward, the movable frame 304 drives the second roller 5 to move downward, thereby reducing the tensioning force of the photovoltaic harness body 6 in the containing shell 1. At this time, the photovoltaic harness body 6 is pulled toward the outside of the containing shell 1, which is convenient for increasing the usable length of the photovoltaic harness body 6, and convenient for adjusting the length of the photovoltaic harness body 6 according to actual needs, so as to facilitate the connection of the photovoltaic harness body 6 and avoid entanglement between adjacent photovoltaic harness bodies 6. Then, through the set second rotating cap 13, it is convenient to rotate the two-way threaded rod 10, and then through the set adapter plug 7, the adapter plugs 7 at both ends of the photovoltaic harness body 6 are convenient for connecting the two devices.

[0029] Working principle: When in use, first rotate the first rotating cap 306, so that the first rotating cap 306 drives the one-way threaded rod 303 to rotate. Since the second limiting groove 302 limits the movable frame 304, the one-way threaded rod 303 drives the movable frame 304 to move upward or downward, thereby causing the movable frame 304 to drive the second roller 5 to move upward or downward. When the movable frame 304 drives the second roller 5 to move upward, it can conveniently increase the tensioning force on the photovoltaic harness body 6, and pull the photovoltaic harness body 6 toward the inside of the accommodating shell 1, thereby reducing the use length of the photovoltaic harness body 6. When the movable frame 304 drives the second roller 5 to move downward, it can reduce the tensioning force on the photovoltaic harness body 6 in the accommodating shell 1. Pulling the photovoltaic harness body 6 from the outside of the housing 1 can increase the usable length of the photovoltaic harness body 6. The length of the photovoltaic harness body 6 can be adjusted according to actual needs. After the adjustment is completed, the second rotating cap 13 is rotated to drive the bidirectional threaded rod 10 to rotate. Since the first limiting groove 9 limits the movable plate 11, the bidirectional threaded rod 10 drives the two movable plates 11 to move relative to each other, and the two movable plates 11 drive the two clamping plates 12 to move relative to each other, thereby clamping and fixing the photovoltaic harness body 6, preventing the photovoltaic harness body 6 from shrinking into the housing 1, causing the photovoltaic harness body 6 to become loose in the housing 1, thereby improving the stability during use, and then the adapter plugs 7 at both ends of the photovoltaic harness body 6 can be inserted into the external equipment accordingly.
