[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Example 1 Figure 1 This is a schematic diagram of the anchoring device for a flexible photovoltaic module connection frame according to Embodiment 1 of this utility model. This anchoring device can be used for fixing steel strands, especially for fixing steel stranded wires, and can be used in flexible photovoltaic module connection frames. See also... Figure 1 This anchoring device includes a compression anchor sleeve 1 for compression fixing of steel strand 6, and an anchoring assembly that cooperates with the compression anchor sleeve 1; the anchoring assembly includes an anchor ring 2 and a pre-tightening clamp 4 disposed inside the anchor ring 2. The anchor ring 2 is coaxially disposed with the compression anchor sleeve 1, and the anchor ring 2 is provided with a trumpet-shaped mounting hole 5 that cooperates with the pre-tightening clamp 4. The large-diameter end of the mounting hole 5 is disposed towards the compression anchor sleeve 1.

[0024] In practical applications, the small-diameter end of the mounting hole 5 on the anchor ring 2 can be used to abut against the photovoltaic bracket. Then, the steel strand 6 is passed through the anchor ring 2, and a pre-tightening clamp 4 is installed inside the mounting hole 5 of the anchor ring 2. The pre-tightening clamp 4 is used to clamp and fix the steel strand 6, forming the first anchoring point. Finally, the compression anchor sleeve 1 can be fitted onto the steel strand 6. After the compression anchor sleeve 1 presses against the pre-tightening clamp 4, the compression anchor sleeve 1 is compressed and anchored using a compression device, so that the compression anchor sleeve 1 and the anchor ring 2 abut against each other to form the second anchoring point. By setting two anchoring points to fix the steel strand 6, not only is the fixing effect of this anchoring device on the steel strand 6 improved, but the assembly of both anchoring points is also very simple, reducing the assembly difficulty of this anchoring device.

[0025] Optionally, both ends of the compression anchor sleeve 1 are provided with tapered ends 8. By providing tapered ends 8 at both ends of the compression anchor sleeve 1, it is not only convenient for the compression equipment to position and compress the compression anchor sleeve 1, thereby improving the compression effect of the compression equipment on the compression anchor sleeve 1, but also helps to control the deformation of the compression anchor sleeve 1 and reduce the possibility of abnormal deformation of the compression anchor sleeve 1 during the compression deformation process.

[0026] Optionally, the outer diameter of the compression anchor sleeve can be smaller than the outer diameter of the anchoring assembly. By setting the outer diameter of the compression anchor sleeve 1 to be smaller than the outer diameter of the anchoring assembly, not only can the overall structural weight of this anchoring device be reduced, saving costs and simplifying assembly, but it can also allow the compression anchor sleeve 1 and the anchoring assembly to form a stable inverted T-shaped structure, which is beneficial to improving the overall structural stability and strength of this anchoring device.

[0027] Preferably, the compression anchor sleeve 1 is provided with a compression spring 7 for fitting onto the steel strand 6. By providing the compression spring 7, when the compression anchor sleeve 1 is compressed by the compression equipment, the compression spring 7 can be broken and further clamp the steel strand 6, preventing the steel strand 6 from moving axially within the compression anchor sleeve 1.

[0028] The anchoring device for a flexible connection frame of photovoltaic modules described in this embodiment has the advantages of simple structure and easy construction and assembly. By setting up a compression anchor sleeve and an anchoring component, the compression anchor sleeve and the anchoring component cooperate to form two anchoring points to fix the steel strand. This not only improves the fixing effect of this anchoring device on the steel strand, but also simplifies the assembly of both anchoring points, reducing the assembly difficulty of this anchoring device.

[0029] Example 2 Figure 2 This is a schematic diagram of the structure of an anchoring device for a flexible connection frame of a photovoltaic module according to Embodiment 2 of this utility model. See also... Figure 2This embodiment is an optimization based on the above embodiment one. Specifically, the optimization is as follows: the above anchoring assembly also includes an anti-loosening cover 3 for limiting the pre-tightening clip 4, which is provided on the anchor ring 2 at the large diameter end corresponding to the assembly hole 5. The anti-loosening cover 3 is detachably installed on the anchor ring 2. The anti-loosening cover 3 is provided with an installation hole that cooperates with the steel strand 6. The compression anchoring sleeve 1 is connected to the anchor ring 2 through the installation hole.

[0030] In practical applications, the end of the anchor ring 2 that is different from the anti-loosening cap 3 can be used to abut against the photovoltaic bracket. Then, the steel strand 6 is passed through the anchor ring 2, and a pre-tightening clamp 4 is installed in the assembly hole 5 of the anchor ring 2. The anti-loosening cap 3 is then installed, which limits the pre-tightening clamp 4, allowing it to clamp and fix the steel strand 6, forming the first anchoring point. Finally, the compression anchor sleeve 1 can be fitted onto the steel strand 6, and the compression anchor sleeve 1 can be compressed and anchored using a compression device. The compression anchor sleeve 1 and the anti-loosening cap abut against each other to form the second anchoring point.

[0031] By setting two anchor points to fix the steel strand 6, the fixing effect of this anchoring device on the steel strand 6 is not only improved, but the assembly of both anchor points is also very simple, reducing the assembly difficulty of this anchoring device. In addition, by setting mounting holes on the anti-loosening cap 3 to mate with the steel strand 6, the mounting holes, the compression anchoring section, and the pre-tightening clamp 4 can achieve three-point positioning of the steel strand 6, which helps to reduce the impact of the vibration of the steel strand 6 on this anchoring device, prevents the anchoring device from loosening, and ensures that the anchoring device can more stably anchor the steel strand 6.

[0032] Preferably, the left and right ends of the compression anchor sleeve 1 are provided with tapered ends 8. By providing tapered ends 8 at the left and right ends of the compression anchor sleeve 1, it is not only convenient for the compression equipment to position and compress the compression anchor sleeve 1, thereby improving the compression effect of the compression equipment on the compression anchor sleeve 1, but also helps to control the deformation of the compression anchor sleeve 1 and reduce the possibility of abnormal deformation of the compression anchor sleeve 1 during the compression deformation process.

[0033] Preferably, the anti-loosening cap 3 has a threaded groove that mates with the anchor ring 2, and the mounting hole communicates with the threaded groove. The anchor ring 2 has an external thread that mates with the threaded groove. By providing a threaded groove on the anti-loosening cap 3 that mates with the anchor ring 2, the stability of the connection between the anti-loosening cap 3 and the anchor ring 2 is improved, thus enhancing the overall structural strength and reliability of the anchoring assembly. Simultaneously, by utilizing the engagement between the threaded groove on the anti-loosening cap 3 and the external thread on the anchor ring 2, the operator can further tighten and fix the pre-tightening clamp 4 by screwing on the anti-loosening cap 3. The inclined surface on the pre-tightening clamp engages with the inner wall of the mounting hole 5, allowing the pre-tightening clamp to better clamp and fix the steel strand 6, thereby improving the anchoring assembly's fixation effect on the steel strand 6.

[0034] In addition, those skilled in the art can also choose other methods to install the anti-loosening cover 3 according to actual needs, so as to achieve a detachable connection between the anti-loosening cover 3 and the anchor ring 2, which will not be elaborated here.

[0035] Optionally, the outer diameter of the compression anchor sleeve 1 can be smaller than the outer diameter of the anti-loosening gland 3. By setting the outer diameter of the compression anchor sleeve 1 to be smaller than the outer diameter of the anti-loosening gland 3, not only can the overall structural weight of this anchoring device be reduced, saving costs and reducing assembly difficulty, but it can also make the compression anchor sleeve 1 and the anti-loosening gland 3 form a stable inverted T-shaped structure, which is beneficial to improving the overall structural stability and structural strength of this anchoring device.

[0036] Preferably, the compression anchor sleeve 1 is provided with a compression spring 7 for fitting onto the steel strand 6. By providing the compression spring 7, when the compression anchor sleeve 1 is compressed by the compression equipment, the compression spring 7 can be broken and further clamp the steel strand 6, preventing the steel strand 6 from moving axially within the compression anchor sleeve 1.

[0037] In practical applications, the diameter of the mounting hole can be smaller than the diameter of the compression spring 7, thereby preventing the compression spring 7 from falling into the mounting hole during installation. This ensures that the compression spring 7 is always stably installed in the compression anchor sleeve 1 and will not break during compression by the compression equipment. This increases the friction between the compression anchor sleeve 1 and the steel strand 6, ensuring that the compression anchor sleeve 1 can stably fix the steel strand 6.

[0038] Preferably, the anti-loosening cover 3 has at least one fastening bolt 11, one end of which extends into the anti-loosening cover 3 and abuts against the anchor ring 2. Exemplarily, one or more fastening bolts 11 may be provided, and the anti-loosening cover 3 has threaded holes for installing the fastening bolts 11. By installing the fastening bolts 11 to abut against the anchor ring 2, the stability of the connection between the anti-loosening cover 3 and the anchor ring 2 is improved.

[0039] In practical applications, the fastening bolts 11 can be set in any of the following ways: 1. One or more fastening bolts 11 are provided at the end of the anti-loosening cover 3 facing the compression anchor sleeve 1; 2. One or more fastening bolts 11 are provided on the side of the anti-loosening cover 3; 3. One or more fastening bolts 11 are provided at both the end of the anti-loosening cover 3 facing the compression anchor sleeve 1 and the side. By setting fastening bolts 11 at the end of the anti-loosening cover 3 facing the compression anchor sleeve 1 and the side, it is beneficial to achieve multi-directional tightening of the anchor ring 2, further improving the stability of the connection between the anti-loosening cover 3 and the anchor ring 2.

[0040] The anchoring device for a flexible photovoltaic module connector described in this embodiment has the advantages of stability and reliability. By setting an anti-loosening pressure cap, it not only limits the pre-tightening clips, ensuring that they can always stably clamp and fix the steel strands, but also provides good protection for the pre-tightening clips, thus improving the safety and reliability of this anchoring device during use. Furthermore, by setting a compression spring inside the compression anchor sleeve, it further enhances the compression and fixing effect of the compression anchor sleeve on the steel strands, ensuring that the compression anchor sleeve can stably fix the steel strands.

[0041] Example 3 Figure 3 This is a schematic diagram of the structure of an anchoring device for a flexible connection frame of a photovoltaic module according to Embodiment 3 of this utility model. See also... Figure 3 This embodiment is an optimization based on the above embodiment 2. Specifically, the optimization is as follows: the compression anchor sleeve 1 and the anti-loosening cover 3 are separate parts, and the end face of one end of the compression anchor sleeve 1 is engaged by pressing against the anti-loosening cover 3.

[0042] In practical applications, after the steel strand is installed, under the tension of the steel strand, the compression anchor sleeve 1 can be limited by pressing against the anti-loosening cover 3. This not only allows the first anchor point and the second anchor point to work together to anchor the steel strand 6, but also allows the compression anchor sleeve 1 to be tightened and limited by pressing against the anti-loosening cover 3, thus preventing the anti-loosening cover 3 from loosening.

[0043] The anchoring device for a flexible connection frame of a photovoltaic module described in this embodiment adopts a split structure of extrusion anchor sleeve and anti-loosening pressure cap. During assembly, the operator can assemble and adjust according to actual needs, which helps to further reduce the assembly difficulty of this anchoring device.

[0044] Example 4 Figure 4 This is a structural schematic diagram of an anchoring device for a flexible connection frame of a photovoltaic module as described in Embodiment 4 of this utility model. See also... Figure 4 This embodiment is an optimization based on the above embodiment 2. Specifically, the optimization is as follows: a positioning sleeve 9 is provided between the compression anchor sleeve 1 and the anti-loosening cover 3; one end of the positioning sleeve 9 is detachably connected to or fixed on the anti-loosening cover 3, and the other end of the positioning sleeve 9 is detachably connected to or fixed on the compression anchor sleeve 1.

[0045] In practical applications, the positioning sleeve 9 can stably cooperate with the steel strand 6, increasing the contact length between the anchoring device and the steel strand 6. This not only extends the cooperation length between the mounting hole and the steel strand 6, but also connects the compression anchoring sleeve 1 and the anti-loosening cap 3, allowing the anchoring device to better limit the movement of the steel strand 6 and reduce its vibration. Simultaneously, by setting the inner diameter of the positioning sleeve 9 to be smaller than the diameter of the compression spring 7, the compression spring 7 is prevented from entering the positioning sleeve 9, ensuring that it remains within the compression anchoring sleeve 1. Furthermore, the positioning sleeve 9 provides good protection for the steel strand 6 between the first and second anchoring points, facilitating construction by operators according to actual needs and improving the safety of this anchoring device during use.

[0046] Preferably, at least one of the positioning sleeve 9, the anti-loosening pressure cap 3, and the anchor ring 2 is provided with a clamping groove 10. Exemplarily, the clamping groove 10 can be provided in any of the following ways: 1. The positioning sleeve 9 is provided with a clamping groove 10; 2. The anti-loosening pressure cap 3 is provided with a clamping groove 10; 3. The anchor ring 2 is provided with a clamping groove 10; 4. The positioning sleeve 9 and the anti-loosening pressure cap 3 are provided with clamping grooves 10; 5. The positioning sleeve 9 and the anchor ring 2 are provided with clamping grooves 10; 6. The anti-loosening pressure cap 3 and the anchor ring 2 are provided with clamping grooves 10; 7. The positioning sleeve 9, the anti-loosening pressure cap 3, and the anchor ring 2 are all provided with clamping grooves 10. By providing clamping grooves 10 on the positioning sleeve 9, the anti-loosening pressure cap 3, and the anchor ring 2, it is easier for operators to use tools to clamp the above-mentioned components for assembly, which helps to reduce the assembly difficulty of the above-mentioned components.

[0047] Preferably, one end of the positioning sleeve 9 is detachably connected to or fixed to the anti-loosening cover 3, and the other end of the positioning sleeve 9 is detachably connected to or fixed to the compression anchor sleeve 1.

[0048] For example, the positioning sleeve 9 can be installed in any of the following ways: 1. One end of the positioning sleeve 9 abuts against the anti-loosening cover 3, and the other end abuts against the compression anchor sleeve 1; 2. One end of the positioning sleeve 9 abuts against the anti-loosening cover 3, and the other end is fixed to the compression anchor sleeve 1; 3. One end of the positioning sleeve 9 is fixed to the anti-loosening cover 3, and the other end abuts against the compression anchor sleeve 1; 4. The left and right ends of the positioning sleeve 9 are fixed to the anti-loosening cover 3 and the compression anchor sleeve 1, respectively.

[0049] Based on the above, the positioning sleeve 9 and the anti-loosening cover 3, and the positioning sleeve 9 and the compression anchor sleeve 1 can also be connected by threads: that is, the positioning sleeve 9 can also be installed in any of the following ways: 1. One end of the positioning sleeve 9 is threaded to the anti-loosening cover 3, and the other end is threaded to the compression anchor sleeve 1; 2. One end of the positioning sleeve 9 is threaded to the anti-loosening cover 3, and the other end is fixed to the compression anchor sleeve 1; 3. One end of the positioning sleeve 9 is fixed to the anti-loosening cover 3, and the other end is threaded to the compression anchor sleeve 1; 4. The left and right ends of the positioning sleeve 9 are fixed to the anti-loosening cover 3 and the compression anchor sleeve 1, respectively.

[0050] For example, when the positioning sleeve 9 and the anti-loosening cover 3, and the positioning sleeve 9 and the compression anchoring sleeve 1 are connected by threads, the positioning sleeve 9 may be provided with external threads, and the anti-loosening cover 3 may be provided with threaded holes that communicate with the mounting holes. Conversely, the anti-loosening cover 3 may be provided with threaded protrusions, and the positioning sleeve 9 may be provided with threaded holes that mate with the threaded protrusions.

[0051] In practical applications, the threaded connection between the positioning sleeve 9 and the compression anchor sleeve 1 is similar. Those skilled in the art can select a suitable threaded connection method according to actual needs to achieve a stable threaded connection between the positioning sleeve 9 and the anti-loosening gland 3, and between the positioning sleeve 9 and the compression anchor sleeve 1. Further details are omitted here. In addition, those skilled in the art can also select other detachable connection methods according to actual needs, which are also omitted here.

[0052] The anchoring device for a flexible connection frame of a photovoltaic module described in this embodiment uses a positioning sleeve between the compression anchor sleeve and the anti-loosening pressure cover. The positioning sleeve can be set to a suitable length according to actual needs, thereby extending the cooperation length between this anchoring device and the steel strand. This helps to better limit the position of the steel strand, improve the stability of the steel strand, and prevent the steel strand from loosening.

[0053] Example 5 Figure 5 This is a structural schematic diagram of an anchoring device for a flexible connection frame of a photovoltaic module as described in Embodiment 5 of this utility model. See also... Figure 5 This embodiment is an optimization based on the above embodiment 2. Specifically, the optimization is that the compression anchor sleeve 1 and the anti-loosening pressure cover 3 are detachably connected.

[0054] For example, the compression anchor sleeve 1 and the anti-loosening pressure cover 3 are connected by threads. One end of the compression anchor sleeve 1 is provided with a threaded connection part, and the anti-loosening pressure cover 3 is provided with a threaded hole that mates with the threaded connection part. The diameter of the threaded hole can be larger than the diameter of the mounting hole.

[0055] Conversely, a threaded connection can also be provided on the anti-loosening cap 3, and the compression anchor sleeve 1 is provided with a threaded hole that mates with the threaded connection. Those skilled in the art can also select a suitable detachable connection method according to actual needs to achieve a detachable connection between the compression anchor sleeve 1 and the anti-loosening cap 3, which will not be elaborated here.

[0056] The anchoring device for a flexible photovoltaic module connector described in this embodiment uses a detachable connection between the compression anchor sleeve and the anti-loosening cap. This improves the stability of the connection between the compression anchor sleeve and the anti-loosening cap, ensuring that the first and second anchoring points can consistently and stably anchor the steel strand together. Simultaneously, the detachable connection between the compression anchor sleeve and the anti-loosening cap reduces the installation difficulty of this anchoring device. Operators can install the anti-loosening cap first, and then assemble the compression anchor sleeve and its internal compression spring.

[0057] Example 6 Figure 6 This is a structural schematic diagram of an anchoring device for a flexible connection frame of a photovoltaic module as described in Embodiment Six of this utility model. See also... Figure 6 This embodiment is an optimization based on the above embodiment 2. Specifically, the optimization is as follows: the compression anchor sleeve 1 is fixed on the anti-loosening pressure cover 3.

[0058] The anchoring device for a flexible connection frame of a photovoltaic module described in this embodiment improves the overall structural strength of the anchoring device by fixing the extrusion anchor sleeve to the anti-loosening pressure cover.

[0059] Example 7 Figure 7 This is a structural schematic diagram of an anchoring device for a flexible connection frame of a photovoltaic module as described in Embodiment 7 of this utility model. See also... Figure 7 This embodiment is an optimization based on the above embodiment one. Specifically, the optimization is that a positioning sleeve 9 is also provided between the compression anchor sleeve 1 and the anchor ring 2.

[0060] For example, one end of the positioning sleeve 9 abuts against the compression anchor sleeve 1, and the other end abuts against the anchor ring 2. In actual use, the inner diameter of the positioning sleeve 9 can be set smaller than the diameter of the compression spring 7, thereby preventing the compression spring 7 from falling into the positioning sleeve 9 during installation, ensuring that the compression spring 7 is always stably installed in the compression anchor sleeve 1 and breaks when compressed by the compression equipment, so as to increase the friction between the compression anchor sleeve 1 and the steel strand 6, and ensure that the compression anchor sleeve 1 can stably fix the steel strand 6.

[0061] Preferably, at least one of the positioning sleeve 9 and the anchor ring 2 is provided with a clamping groove 10. Exemplarily, the clamping groove 10 can be provided in any of the following ways: 1. The positioning sleeve 9 is provided with a clamping groove 10; 2. The anchor ring 2 is provided with a clamping groove 10; 3. Both the positioning sleeve 9 and the anchor ring 2 are provided with clamping grooves 10. By providing clamping grooves 10 on the positioning sleeve 9 and the anchor ring 2, it is easier for operators to use tools to clamp the aforementioned components for assembly, which helps to reduce the assembly difficulty of the aforementioned components.

[0062] The anchoring device for a flexible connection frame of a photovoltaic module described in this embodiment uses a positioning sleeve 9 between the compression anchor sleeve 1 and the anchor ring 2. The positioning sleeve 9 can be set to a suitable length according to actual needs, thereby extending the cooperation length between this anchoring device and the steel strand 6. This helps to better limit the position of the steel strand 6, improve the stability of the steel strand 6, and prevent the steel strand 6 from loosening.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
