Description

Technical Field

[0001] This utility model relates to the field of power fittings technology, and in particular to a ball-head hanging ring that is easy to install. Background Technology

[0002] Ball-head hangers are connecting parts between iron towers and insulators on power transmission lines. They are electrical devices used to connect insulating suspension plates and are often used to fix conductive wires on insulators. Because hangers are widely used on power transmission lines, they are one of the important components related to the safe operation of overhead power transmission lines.

[0003] Traditional ball joint rings are mostly one-piece molded structures. Since the length of the ball joint ring is fixed, the distance between different connection structures varies in actual applications. The fixed-length ball joint ring is difficult to adapt to these changes, which limits its applicability and reduces the flexibility of use. Therefore, we propose a ball joint ring that is easy to install. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a ball-head hanging ring that is easy to install.

[0005] This utility model is achieved using the following technical solution: a ball-head hanging ring that is easy to install, including a ball head, an extension block fixedly connected to the top of the ball head, a fixing rod slidably connected to the surface of the extension block, a plurality of through holes evenly distributed on the inner walls of the extension block and the fixing rod, a hanging ring fixedly connected to the top of the fixing rod, a fixing component provided on the outside of the fixing rod, and a locking component provided at the upper end of the fixing component;

[0006] The fixing component includes a U-shaped rod, the right end of which is threaded with a nut, and a positioning hole is provided at the right end of the U-shaped rod.

[0007] The above technical solution involves pulling the ball head to make the extension block slide on the inner wall of the fixed rod. After adjustment, the U-shaped rod is inserted into the two through holes, and the nut is threaded to one end of the U-shaped rod to fix the position of the extension block and the fixed rod. The distance between the ball head and the hanging ring is adjusted to facilitate adjustment according to the distance between the connecting structures, which is convenient for subsequent installation. The two nuts are connected by two rods at one end of the U-shaped rod to ensure the stability after installation.

[0008] As a further improvement to the above solution, the U-shaped rod passes through the extension block and the fixing rod via a through hole, and the nut is located on the right side of the fixing rod.

[0009] With the above technical solution, when the U-shaped rod is inserted into the through hole, the positioning hole is positioned upwards, which facilitates the subsequent locking assembly to fix it.

[0010] As a further improvement to the above solution, the locking assembly includes a fixing plate, a mounting bracket fixedly connected to the top of the fixing plate, a limit rod slidably connected to the inner wall of the fixing plate, a pull ring fixedly connected to the top of the limit rod, a spring sleeved on the surface of the limit rod, and a limit ring fixedly connected to the surface of the limit rod.

[0011] With the above technical solution, by pulling the pull ring, the pull ring drives the limiting rod to move. At the same time, the movement of the limiting ring compresses the spring. At this time, the mounting bracket will not block the through hole position. When fixing, the pull ring is released, and the spring elastically returns to its original position, pushing the limiting ring so that the limiting rod moves downward and enters the interior of the positioning hole, which plays a limiting role on the U-shaped rod and the nut, preventing the nut from loosening, effectively preventing accidental fall-off, and improving the safety during use.

[0012] As a further improvement to the above solution, the left end of the fixing plate is fixedly connected to the surface of the fixing rod, and the lower end of the limiting rod extends into the interior of the positioning hole.

[0013] Through the above technical solution, the limiting rod passes through the positioning hole through the U-shaped rod, preventing the U-shaped rod from moving and ensuring the stability of the connection.

[0014] As a further improvement to the above solution, the surface of the limiting rod is slidably connected to the inner wall of the mounting bracket, and the pull ring is located at the top of the mounting bracket.

[0015] With the above technical solution, since the limiting rod is slidably connected to the inner wall of the fixing frame and the mounting frame, the deviation of the limiting rod during movement is avoided, which facilitates subsequent precise docking. The pull ring facilitates operation during use and improves the convenience of operation.

[0016] As a further improvement to the above solution, the top of the spring is fixedly connected to the top of the inner wall of the mounting bracket.

[0017] As a further improvement to the above solution, the bottom of the spring contacts the top of the limiting ring.

[0018] With the above technical solution, when the limiting rod moves, it will drive the limiting ring to move. Since the diameter of the limiting ring is larger than the diameter of the spring, it will compress the spring.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model uses an extension block, a fixing rod, and a fixing assembly. Specifically, the extension block slides on the inner wall of the fixing rod by pulling the ball head. After adjustment, the U-shaped rod is inserted into the two through holes, and the nut is threaded to one end of the U-shaped rod to fix the position of the extension block and the fixing rod. The distance between the ball head and the hanging ring is adjusted to facilitate adjustment according to the distance between the connecting structures, which is convenient for subsequent installation. The two nuts are connected by two rods at one end of the U-shaped rod to ensure the stability after installation.

[0021] This utility model incorporates a locking component. Specifically, by releasing the pull ring, the spring elastically returns and pushes the limiting ring, causing the limiting rod to move downward and enter the positioning hole. This limits the U-shaped rod and the nut, preventing the nut from loosening and effectively preventing accidental detachment, thus improving safety during use. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5This embodiment provides a convenient ball head hanging ring, including a ball head 1, an extension block 2 fixedly connected to the top of the ball head 1, a fixing rod 3 slidably connected to the surface of the extension block 2, a plurality of equally spaced through holes 4 on the inner walls of both the extension block 2 and the fixing rod 3, a hanging ring 5 fixedly connected to the top of the fixing rod 3, a fixing component 6 provided on the outside of the fixing rod 3, and a locking component 7 provided at the upper end of the fixing component 6;

[0032] The fixing component 6 includes a U-shaped rod 601, with a nut 602 threadedly connected to the right end of the U-shaped rod 601. A positioning hole 603 is provided at the right end of the U-shaped rod 601. When it is necessary to adjust the length between the ball head 1 and the hanging ring 5, the ball head 1 is pulled to make the extension block 2 slide on the inner wall of the fixing rod 3. After the adjustment is completed, the U-shaped rod 601 is inserted into the two through holes 4, and the nut 602 is threadedly connected to one end of the U-shaped rod 601 to fix the position of the extension block 2 and the fixing rod 3. The distance between the ball head 1 and the hanging ring 5 is adjusted to facilitate adjustment according to the distance between the connecting structures, which is convenient for subsequent installation. The two nuts 602 are connected by two rods at one end of the U-shaped rod 601 to ensure the stability after installation.

[0033] The U-shaped rod 601 passes through the through hole 4, extending through the extension block 2 and the fixing rod 3, with the nut 602 located on the right side of the fixing rod 3.

[0034] The locking assembly 7 includes a fixing plate 701, a mounting bracket 702 fixedly connected to the top of the fixing plate 701, a limit rod 703 slidably connected to the inner wall of the fixing plate 701, a pull ring 704 fixedly connected to the top of the limit rod 703, a spring 705 sleeved on the surface of the limit rod 703, and a limit ring 706 fixedly connected to the surface of the limit rod 703. By pulling the pull ring 704, the pull ring 704 drives the limit rod 703 to move, and at the same time, the limit ring 706 moves to compress the spring 705. At this time, the mounting bracket 702 will not block the position of the through hole 4. When fixing, the pull ring 704 is released, the spring 705 elastically returns to its original position and pushes the limit ring 706, so that the limit rod 703 moves downward and enters the interior of the positioning hole 603, which plays a limiting role on the U-shaped rod 601 and the nut 602, preventing the nut 602 from loosening, effectively preventing accidental fall-off, and improving safety during use.

[0035] The left end of the fixing plate 701 is fixedly connected to the surface of the fixing rod 3, and the lower end of the limiting rod 703 extends into the interior of the positioning hole 603.

[0036] The surface of the limiting rod 703 is slidably connected to the inner wall of the mounting bracket 702, and the pull ring 704 is located at the top of the mounting bracket 702.

[0037] The top of the spring 705 is fixedly connected to the top of the inner wall of the mounting bracket 702.

[0038] The bottom of spring 705 contacts the top of limit ring 706.

[0039] The implementation principle of the ball-head hanging ring that is easy to install in this embodiment is as follows: When it is necessary to adjust the length between the ball head 1 and the hanging ring 5, pull the ball head 1 to make the extension block 2 slide on the inner wall of the fixing rod 3. After the adjustment is completed, first pull the ring 704. The ring 704 drives the limiting rod 703 to move. At the same time, the limiting ring 706 moves to compress the spring 705. At this time, the mounting bracket 702 will not block the position of the through hole 4. Then, insert the U-shaped rod 601 into the two through holes 4, and thread the nut 602 to one end of the U-shaped rod 601 to connect the extension block 2 and the fixing rod 3. The position is fixed, and the distance between the ball head 1 and the hanging ring 5 is adjusted to facilitate adjustment according to the distance between the connecting structures, which is convenient for subsequent installation. Two nuts 602 are connected by two rods at one end of the U-shaped rod 601 to ensure stability after installation. Then, the pull ring 704 is loosened, and the spring 705 elastically returns to its original position, pushing the limiting ring 706, so that the limiting rod 703 moves downward and enters the interior of the positioning hole 603, which limits the U-shaped rod 601 and the nut 602, preventing the nut 602 from loosening, effectively preventing accidental fall-off, and improving safety during use.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
