Description

Technical Field

[0001] This utility model relates to the field of surge arrester technology, and in particular to a surge arrester structure. Background Technology

[0002] A surge arrester is connected between the cable and the ground, usually in parallel with the protected equipment. Surge arresters effectively protect communication equipment; they activate in the event of abnormal voltage to provide protection. When the communication cable or equipment is operating under normal operating voltage, the surge arrester does not function and is considered an open circuit to the ground. However, if a high voltage occurs that threatens the insulation of the protected equipment, the surge arrester immediately activates, diverting the high-voltage surge current to the ground, thereby limiting the voltage amplitude and protecting the insulation of the communication cable and equipment. Once the overvoltage dissipates, the surge arrester quickly returns to its original state, allowing the communication line to operate normally.

[0003] Surge arresters typically have verticality and angle requirements during installation, depending on the type of arrester and its operating environment. Currently, most surge arresters are installed using a fixed structure, which makes angle adjustment difficult once installed, limiting their deployment capabilities in complex environments. Furthermore, the bottom connection of surge arresters usually uses threads or welding, making disassembly and assembly inconvenient and unable to meet the needs of frequent replacement or maintenance. The connection between the connector and the base is generally rigid, lacking quick disassembly and locking mechanisms, resulting in cumbersome maintenance and replacement processes. Fixing requires both hands simultaneously, leading to low efficiency and poor safety. Therefore, there is an urgent need for a surge arrester structure that is more stable, more precise in adjustment, and more convenient to operate. Utility Model Content

[0010] Preferably, there are gaps between the connecting plate and the top of the ball seat and the inner wall of the vertical baffle.

The four slide rails are slidably connected to the four guide blocks respectively.

[0011] Preferably, there are two sets of linkage mechanisms, and the two sets of linkage mechanisms are symmetrically arranged on both sides of the two connecting plates.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model constructs a modular assembly and disassembly structure by setting a threaded rod, a connector, and a connecting seat at the bottom of the surge arrester body, enabling rapid connection and separation between the surge arrester and the base. The connector, through the engagement of the locking block and the locking groove of the connecting seat, can achieve tool-free locking and fixing.

[0016] 3. This utility model, by setting guide blocks on both sides of the connecting plate, which cooperate with the slide rail on the inner wall of the vertical baffle, further improves the guiding and stability of the snap ring movement process, effectively avoiding jamming or displacement during snap ring locking. Simultaneously, symmetrical linkage mechanisms are set on both sides of the gear, supplemented by connecting shafts and bearings for support, achieving force balance and coordinated action during transmission. This not only improves the overall mechanical strength of the structure but also extends its service life, adapting to the high-efficiency operation requirements of various complex installation environments.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-9A surge arrester structure includes a surge arrester body 1, a threaded rod 2 fixedly connected to the bottom of the surge arrester body 1, a connector 3 fixedly connected to the bottom of the threaded rod 2, a connector 4 engaged with the connector 3, and a rotating ball 6 fixedly connected to the bottom of the connector 4 via a connecting rod 5; a base 7, including a fixing plate 701, a ball seat 702 fixedly connected to the top of the fixing plate 701, a hemispherical socket 703 matching the rotating ball 6 on the ball seat 702, the bottom of the rotating ball 6 rotatably mounted in the hemispherical socket 703, and vertical baffles 704 circumferentially connected to the top of the four side walls of the ball seat 702, with two phases slidably disposed on the inner wall of the vertical baffles 704. The two symmetrical connecting plates 705 are each fixedly connected to a semi-circular retaining ring 706 on the side closest to each other. The inner walls of the two semi-circular retaining rings 706 are tightly fitted to the outer wall of the top of the rotating ball 6. The linkage mechanism includes a gear 8 and a bolt 11. The gear 8 is meshed with an upper rack 9 and a lower rack 10, respectively. The upper rack 9 and the lower rack 10 are fixedly connected to the two connecting plates 705, respectively. The upper rack 9, the lower rack 10 and the bolt 11 are arranged in the same direction. The bolt 11 is threadedly connected to the vertical baffle 704 and its end passes through the vertical baffle 704 and is fixedly connected to a nearby connecting plate 705.

[0029] In this embodiment, the present invention achieves a detachable connection between the surge arrester body 1 and the base 7 through the combination of the surge arrester body 1, threaded rod 2, connector 3, connecting seat 4, connecting rod 5, and rotating ball 6, which facilitates quick installation and replacement. The rotating ball 6 cooperates with the hemispherical socket 703 on the ball seat 702 to form a rotatable structure, enabling the surge arrester to have an adjustable angle. The vertical baffle 704 cooperates with the connecting plate 705 slidably disposed on its inner wall. The semi-circular retaining ring 706 disposed on the connecting plate 705 can achieve a stable locking of the rotating ball 6, ensuring that the angle is fixed and does not deviate. The gear 8, upper rack 9, lower rack 10, and bolt 11 in the linkage mechanism are linked. By rotating the bolt 11, the gear 8 can be driven to rotate, and then the upper rack 9 and lower rack 10 simultaneously drive the two connecting plates 705 to move synchronously, so that the retaining ring 706 can open and close synchronously, which greatly improves the adjustment efficiency and locking reliability.

[0030] In this utility model, the connector 3 includes a connecting post 301 whose top is fixedly connected to the threaded rod 2. Several locking blocks 304 are evenly distributed on the bottom side wall of the connecting post 301 and fixedly connected thereto. A protective cover 303 is connected to the top of the connecting post 301 through a spring 302. The bottom of the threaded rod 2 moves through the protective cover 303 and the spring 302 and is fixedly connected to the connecting post 301. A nut 201 is threadedly connected to the threaded rod 2. The bottom of the nut 201 is tightly fitted to the top of the protective cover 303.

[0031] In this embodiment, a connector 3 with protective and positioning functions is constructed by setting up a connecting post 301, a locking block 304, a protective cover 303, and a spring 302. The connecting post 301 is firmly connected to the threaded rod 2, and the locking blocks 304 evenly distributed at its lower end enable quick engagement with the connecting seat 4. The protective cover 303 is elastically connected to the connecting post 301 via the spring 302, and can automatically spring back when not locked. After the nut 201 is tightened, its bottom presses against the protective cover 303, causing the protective cover 303 to loosen or fall off, thereby improving the stability of the entire connecting device.

[0032] In this utility model, the connecting seat 4 includes a column 401. The top of the column 401 is provided with a cylindrical groove 402 corresponding to the connecting column 301. The inner wall of the cylindrical groove 402 is provided with a slot 404 that matches a plurality of locking blocks 304. The plurality of locking blocks 304 are respectively engaged and connected in the plurality of slots 404. The top of the end of each of the plurality of slots 404 is connected to a slot 403 that matches the locking block 304. The plurality of slots 403 are respectively located on the same side of the plurality of slots 404 and penetrate the top of the cylindrical groove 402. The top of the column 401 is provided with a plurality of limiting holes 405. Each of the plurality of limiting holes 405 is movably inserted into a limiting block 305. The top of each of the plurality of limiting blocks 305 is fixedly connected to the bottom of the protective cover 303.

[0033] In this embodiment, a connector 4 with quick connection and anti-detachment functions is constructed by setting up a column 401, a columnar groove 402, a slot 404, a slot 403, a limiting hole 405, and a limiting block 305. Specifically, the column 401 has a columnar groove 402 at its top corresponding to the connecting column 301, and the slot 404 on its inner wall precisely matches the locking block 304, achieving quick and stable insertion and engagement. The slot 403 is located on the same side as the slot 404 and extends through the top of the columnar groove 402, facilitating the smooth insertion of the locking block 304 and improving assembly convenience. The limiting hole 405 at the top of the column 401 is fitted with a limiting block 305, which is fixedly connected to the bottom of the protective cover 303. This provides additional structural limitation after assembly, effectively preventing the locking block 304 from detaching due to vibration or external force, thereby enhancing the overall structural connection reliability and safety.

[0034] In this invention, the two semi-circular retaining rings 706 are symmetrical to each other and have a gap between them. The inner walls of the two semi-circular retaining rings 706 are densely covered with fine teeth 707.

[0035] In this embodiment, by setting two symmetrical semi-circular retaining rings 706 and fine teeth 707 densely distributed on their inner walls, a stable clamping and anti-slip locking function is achieved for the top of the rotating ball 6. The gap between the two semi-circular retaining rings 706 helps to coordinate with the linkage mechanism for opening and closing adjustment, thereby facilitating the position adjustment and positioning operation of the rotating ball 6. When the retaining rings 706 close and clamp the rotating ball 6, the fine teeth 707 on their inner walls can generate frictional engagement with the outer surface of the rotating ball 6, improving contact stability and preventing the rotating ball 6 from rotating and slipping due to external forces or gravity during use, further ensuring the accuracy and reliability of the installation angle of the surge arrester body 1.

[0036] In this utility model, there are gaps between the connecting plate 705 and the top of the ball seat 702 and the inner wall of the vertical baffle 704. Guide blocks 708 are fixedly connected to both sides of the two connecting plates 705. Four slide rails 709 arranged in the same direction as the upper rack 9 and the lower rack 10 are fixedly connected to the inner wall of the vertical baffle 704. The four slide rails 709 are slidably connected to the four guide blocks 708 respectively.

[0037] In this embodiment, a reasonable gap is set between the connecting plate 705 and the top of the ball seat 702 and the inner wall of the vertical baffle 704, and guide blocks 708 are set on both sides of the connecting plate 705. These, along with the slide rail 709 installed on the inner wall of the vertical baffle 704, form a stable sliding guide structure. The sliding cooperation between the guide blocks 708 and the slide rail 709 ensures that the connecting plate 705 moves precisely in a preset direction under the drive of the linkage mechanism, avoiding deviation or jamming during adjustment, improving the smoothness of operation and the overall reliability of the mechanism. Simultaneously, it provides accurate guidance for the meshing motion of the upper rack 9 and lower rack 10 with the gear 8, facilitating precise control of the clamping and releasing of the rotating ball 6, and further enhancing the effect of arrester angle adjustment and locking.

[0038] In this utility model, there are two sets of linkage mechanisms, and the two sets of linkage mechanisms are symmetrically arranged on both sides of the two connecting plates 705. The two gears 8 are fixedly connected to the side away from each other by a connecting shaft 12. The ends of the two connecting shafts 12 are rotatably connected to the inner wall of the vertical baffle 704 through a bearing 13.

[0039] In this embodiment, by symmetrically arranging two sets of linkage mechanisms on both sides of the two connecting plates 705, the clamping mechanism is subjected to balanced force and synchronized transmission, effectively avoiding the problem of offset or insecure clamping caused by unilateral force. The two gears 8 are rotatably connected to the bearings 13 on the inner wall of the vertical baffle 704 through their respective connecting shafts 12, which not only ensures the stable operation and precise transmission of the gears 8, but also significantly reduces running resistance and wear, thereby improving the durability and smooth operation of the entire structure, ensuring that the clamping process of the rotating ball 6 is more reliable and efficient, and providing solid support for the angle adjustment and stable fixation of the surge arrester.

[0040] In this utility model, the fixing plate 701 has a plurality of mounting holes 710.

[0041] In this embodiment, by opening a plurality of mounting holes 710 on the fixing plate 701, it is convenient to fix the surge arrester structure in the installation position, so that the surge arrester can be connected to other equipment or support structures.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
