Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically a foldable, anti-detachment, and cold-shrinkable outdoor terminal fixing structure. Background Technology

[0002] Cable terminations are structures that integrate waterproofing, stress control, shielding, and insulation. They are typically installed at the end of cables and are mainly divided into indoor and outdoor terminations. They have good electrical and mechanical properties. Outdoor terminations usually require a fixed structure for restraint and support during installation before the terminals are connected to the power grid. This is to prevent the outdoor termination from being too heavy and causing the connection structure to deform or break due to excessive stress, and to prevent the outdoor termination from shaking due to external forces such as wind, which could affect the stability of the terminal connection.

[0003] Existing outdoor terminal fixing structures typically use steel structures such as channel steel and angle steel welded into an integrated bracket. The bracket is tower-shaped or grid-shaped, used with accessories such as insulators and flange plates, and supported by a reinforced concrete base. The bracket of the fixing structure is heavy and bulky. During transportation by trolleys, forklifts, or other vehicles, the long length of the bracket makes it easy for the two ends to collide. Or, during manual handling, multiple workers are required, otherwise the center of gravity will shift and it will easily fall to the ground. The operation is time-consuming, labor-intensive, and inconvenient. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a foldable, anti-detachment, and cold-shrinkable outdoor terminal fixing structure to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable, anti-detachment, cold-shrink outdoor terminal fixing structure, including a base and a mounting plate. The top of the mounting plate is respectively connected to a first longitudinal frame and a second longitudinal frame, and a first horizontal frame is fixed to the top of the first longitudinal frame. A first limiting plate and a second limiting plate are respectively connected to one side of the back of the first horizontal frame. A second horizontal frame is fixed to the top of the second longitudinal frame. A hinge is connected between the first horizontal frame and the second horizontal frame. A rotating frame is connected to the back of the second horizontal frame, and a screw is connected to one end of the rotating frame.

[0006] By adopting the above technical solution, firstly, when handling is required, the worker rotates the second horizontal frame upwards, shortening the support structure composed of the first vertical frame, first horizontal frame, second vertical frame, and second horizontal frame by half. Then, the worker rotates the screw to be perpendicular to the second limiting plate using the rotating frame, and subsequently tightens the nut on the screw to press against the second limiting plate, thereby limiting the second horizontal frame and preventing it from rotating arbitrarily and affecting handling and transportation. Furthermore, the first vertical frame, first horizontal frame, second vertical frame, and second horizontal frame are made of aluminum alloy, which has the advantages of being lightweight and high-strength. Reducing the structural weight further facilitates the worker's handling and transportation of the structure. Furthermore, aluminum alloy has excellent corrosion resistance, making it suitable for long-term outdoor use. Upon arrival at the designated location, workers place the first longitudinal frame on the mounting plate. Then, workers loosen the nut on the screw and rotate the screw using a rotating frame to separate the screw from the second limiting plate, thus ending the limitation on the second horizontal frame. Workers then reverse the second horizontal frame to unfold it and restore the original length of the support structure, with the second longitudinal frame in contact with the mounting plate. Afterward, workers rotate the screw using the rotating frame until it is perpendicular to the first limiting plate, and then tighten the nut on the screw to press against the first limiting plate, thereby limiting the second horizontal frame and ensuring that the second horizontal frame is flush with the first horizontal frame.

[0007] Furthermore, the second crossbeam is rotatably connected to the first crossbeam via a hinge.

[0008] By adopting the above technical solution, when it is necessary to move the equipment, the second crossbeam can be rotated upwards, so that the support composed of the first longitudinal frame, the first crossbeam, the second longitudinal frame, and the second crossbeam can be shortened by half, thus facilitating handling and transportation; when it is needed for use, the second crossbeam can be reversed to unfold the structure and restore its original length, so as to facilitate the fixing of the outdoor terminal.

[0009] Furthermore, the rotating frame is rotatably connected to the second cross frame, and the first limiting plate and the second limiting plate are perpendicularly distributed.

[0010] By adopting the above technical solution, when folding, the screw can be rotated to be perpendicular to the second limiting plate by the rotating frame; when in use, the screw can be rotated to be perpendicular to the first limiting plate by the rotating frame.

[0011] Furthermore, the screw is detachably connected to the first limiting plate and the second limiting plate, and the cross-sections of the first limiting plate and the second limiting plate are both "n" shaped.

[0012] By adopting the above technical solution, the nut on the screw is tightened to abut against the first or second limiting plate, thereby facilitating the limiting of the second crossbar in the folded or used state.

[0013] Furthermore, the base is made of reinforced concrete, and the mounting plate extends through the top of the base. The mounting plate is connected to the first longitudinal frame and the second longitudinal frame by mounting bolts.

[0014] By adopting the above technical solution, workers pre-fabricated a base at the installation location by binding steel bars and pouring concrete, and then fixed the mounting plate to the base to facilitate the subsequent installation of the structure.

[0015] Furthermore, there are four of each of the following: the second crossbeam, hinge, rotating frame, screw, first limiting plate, and second limiting plate; and the four second crossbeams, hinges, rotating frames, screws, first limiting plates, and second limiting plates are mirror images of each other.

[0016] By adopting the above technical solution, the structure can be easily folded to half its length, making it easier to transport. At the same time, it is easy to limit the movement during folding and unfolding, thus improving stability.

[0017] Furthermore, there are two of each of the base, mounting plate, first longitudinal frame, first transverse frame and second longitudinal frame, and the two first longitudinal frames, first transverse frame and second longitudinal frame are mirror images of each other.

[0018] By adopting the above technical solution, it is convenient to support the four foldable second crossbars, and to facilitate the installation of the bracket composed of the first longitudinal frame, the first crossbar, the second longitudinal frame, and the second crossbar.

[0019] Furthermore, the top of the first crossbeam and the second crossbeam are respectively connected to twelve insulators, and the top of each of the twelve insulators is connected to three flange plates. The top of the three flange plates is through which a terminal cable passes, and the terminal cable is sleeved with a cold shrink sleeve. The top of the terminal cable is connected to three terminals.

[0020] By adopting the above technical solution, the workers first installed twelve insulators on two first crossbeams and four second crossbeams respectively. Then, the workers passed the terminal cable between the two first crossbeams and four second crossbeams and installed cold shrink sleeves, terminals, flange plates, etc. After the outdoor terminal was made, the workers installed the flange plates on the insulators.

[0021] Furthermore, the first longitudinal frame, the first transverse frame, the second longitudinal frame, and the second transverse frame are all made of aluminum alloy.

[0022] By adopting the above technical solution, it has the advantages of light weight and high strength. The reduction of structural weight makes it easier for staff to maintain and transport the structure. In addition, aluminum alloy has excellent corrosion resistance, which is suitable for long-term outdoor use.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model, through the arrangement of a first vertical frame, a first horizontal frame, a second vertical frame, a second horizontal frame, and a hinge, allows the second horizontal frame to be rotated upwards when transporting, shortening the support structure composed of the first vertical frame, the first horizontal frame, the second vertical frame, and the second horizontal frame by half its length, thus facilitating handling and transportation; when in use, simply reverse the second horizontal frame to unfold the structure and restore its original length, facilitating the fixing of the outdoor terminal; the structure can be easily folded during transportation and handling, thus simplifying transportation and handling.

[0025] 2. This utility model, through the arrangement of a rotating frame, a screw, a first limiting plate, and a second limiting plate, allows for folding. During folding, the screw can be rotated perpendicular to the second limiting plate via the rotating frame, and then the nut on the screw can be tightened to press against the second limiting plate, thereby limiting the second crossbeam and preventing it from rotating arbitrarily, which would affect handling and transportation. During use, the screw can be rotated perpendicular to the first limiting plate via the rotating frame, and then the nut on the screw can be tightened to press against the first limiting plate, thereby limiting the second crossbeam and increasing structural stability. This facilitates structural limiting and improves stability. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1:

[0035] Foldable, anti-detachment, and cold-shrink outdoor terminal fixing structure, such as Figures 1-5 As shown, the system includes a base 1 and a mounting plate 2. A first longitudinal frame 9 and a second longitudinal frame 11 are connected to the top of the mounting plate 2. A first transverse frame 10 is fixed to the top of the first longitudinal frame 9.

The first limiting plate 16 and the second limiting plate 17 are perpendicularly distributed, and both the first limiting plate 16 and the second limiting plate 17 have an "n"-shaped cross-section. A second transverse frame 12 is fixed to the top of the second longitudinal frame 11. A hinge 13 connects the first transverse frame 10 and the second transverse frame 12, allowing the second transverse frame 12 to be rotatably connected to the first transverse frame 10 via the hinge 13. A rotating frame is connected to the back of the second transverse frame 12. 14. The rotating frame 14 is rotatably connected to the second crossbeam 12. One end of the rotating frame 14 is connected to a screw 15. The screw 15 is detachably connected to the first limiting plate 16 and the second limiting plate 17. There are four of each of the following: second crossbeam 12, hinge 13, rotating frame 14, screw 15, first limiting plate 16, and second limiting plate 17. The four second crossbeams 12, hinges 13, rotating frame 14, screw 15, first limiting plate 16, and second limiting plate 17 are mirror images of each other. When it is necessary to move the equipment, the operator rotates the second crossbeam 12 upwards, so that the support frame composed of the first longitudinal frame 9, the first crossbeam 10, the second longitudinal frame 11, and the second crossbeam 12 can be shortened. Half the length, then the workers rotate the screw 15 to be perpendicular to the second limiting plate 17 using the rotating frame 14, and then tighten the nut on the screw 15 to abut against the second limiting plate 17, thereby limiting the second horizontal frame 12 and preventing the second horizontal frame 12 from rotating arbitrarily and affecting handling and transportation. The first longitudinal frame 9, the first horizontal frame 10, the second longitudinal frame 11, and the second horizontal frame 12 are made of aluminum alloy, which has the advantages of light weight and high strength. Reducing the structural weight further facilitates the workers' handling and transportation of the structure. Aluminum alloy also has excellent corrosion resistance, making it suitable for long-term outdoor use. When transported to the designated location, the workers place the first longitudinal frame... 9 is placed on the mounting plate 2. Then, the operator loosens the nut on the screw 15 and rotates the screw 15 through the rotating frame 14 to separate the screw 15 from the second limiting plate 17, thereby ending the limitation of the second cross frame 12. Then, the operator reverses the second cross frame 12 to unfold and restore the original length of the support structure, and the second longitudinal frame 11 contacts the mounting plate 2. Then, the operator rotates the screw 15 through the rotating frame 14 to be perpendicular to the first limiting plate 16, and then tightens the nut on the screw 15 to press against the first limiting plate 16, thereby limiting the second cross frame 12 and ensuring that the second cross frame 12 is flush with the first cross frame 10.

[0036] See Figures 1-5In the above embodiment, the base 1 is made of reinforced concrete, and the mounting plate 2 extends through the top of the base 1. Mounting bolts 3 connect the mounting plate 2 to both the first longitudinal frame 9 and the second longitudinal frame 11. Two of each of the base 1, mounting plate 2, first longitudinal frame 9, first transverse frame 10, and second longitudinal frame 11 are provided, and the two first longitudinal frames 9, first transverse frames 10, and second longitudinal frames 11 are mirror images of each other. Workers fix the first longitudinal frames 9 and second longitudinal frames 11 to the mounting plate 2 using the mounting bolts 3. Twelve insulating rings are respectively connected to the top of the first transverse frame 10 and the second transverse frame 12. The twelve insulators 8 are connected to three flange plates 7 on their tops. The terminal cable 4 passes through the top of the three flange plates 7. The terminal cable 4 is fitted with a cold shrink sleeve 5. The top of the terminal cable 4 is connected to three terminals 6. The workers first install the twelve insulators 8 on two first cross frames 10 and four second cross frames 12 respectively. Then the workers pass the terminal cable 4 between the two first cross frames 10 and four second cross frames 12 and install the cold shrink sleeve 5, terminals 6, flange plates 7, etc. After the outdoor terminal is made, the workers install the flange plates 7 on the insulators 8.

[0037] Example 2:

[0038] Based on the above embodiment one, the following settings are now implemented to further improve practicality.

[0039] See Figures 1-5 In the above embodiments, the first longitudinal frame 9, the first transverse frame 10, the second longitudinal frame 11, and the second transverse frame 12 are all made of aluminum alloy, which has the advantages of light weight and high strength. By reducing the structural weight, it is easier for workers to maintain and transport the structure. In addition, aluminum alloy has excellent corrosion resistance, which is convenient for long-term outdoor use.

[0040] The implementation principle of this utility model is as follows: First, when it is necessary to move the structure, the worker rotates the second horizontal frame 12 upwards, so that the support composed of the first vertical frame 9, the first horizontal frame 10, the second vertical frame 11, and the second horizontal frame 12 can be shortened by half. Then, the worker rotates the screw 15 to be perpendicular to the second limiting plate 17 by rotating the frame 14. Then, the nut on the screw 15 is tightened to abut against the second limiting plate 17, thereby limiting the second horizontal frame 12 and preventing the second horizontal frame 12 from rotating arbitrarily, which would affect the handling and transportation. Moreover, the first vertical frame 9, the first horizontal frame 10, the second vertical frame 11, and the second horizontal frame 12 are made of aluminum alloy, which has the advantages of light weight and high strength. By reducing the structural weight, it is easier for the worker to carry out the structure. In addition, aluminum alloy has excellent corrosion resistance and is suitable for long-term outdoor use.

[0041] When transported to the designated location, the staff places the first longitudinal frame 9 on the mounting plate 2. Then, the staff loosens the nut on the screw 15 and rotates the screw 15 through the rotating frame 14 to separate the screw 15 from the second limiting plate 17, thereby ending the limitation on the second horizontal frame 12. Then, the staff reverses the second horizontal frame 12 to unfold and restore the original length of the support structure, and the second longitudinal frame 11 contacts the mounting plate 2. Then, the staff rotates the screw 15 through the rotating frame 14 to be perpendicular to the first limiting plate 16. Then, the staff tightens the nut on the screw 15 to press against the first limiting plate 16, thereby limiting the second horizontal frame 12 and ensuring that the second horizontal frame 12 is flush with the first horizontal frame 10. Then, the staff fixes the first longitudinal frame 9 and the second longitudinal frame 11 to the mounting plate 2 with the mounting bolts 3.

[0042] After fixing the first longitudinal frame 9 and the second longitudinal frame 11, the workers first install the twelve insulators 8 on the two first horizontal frames 10 and the four second horizontal frames 12 respectively. Then, the workers pass the terminal cable 4 through the two first horizontal frames 10 and the four second horizontal frames 12 and install the cold shrink sleeve 5, terminal 6, flange plate 7, etc. After the outdoor terminal is made, the workers install the flange plate 7 on the insulator 8, thus completing the installation operation.
