Description

Technical Field

[0001] This utility model relates to the field of grounding leads, specifically a ring-shaped concrete pole grounding lead fixing structure with a self-locking buckle. Background Technology

[0002] Concrete poles are poles made of concrete and reinforcing steel bars or wires, and are mainly divided into prestressed concrete poles and non-prestressed concrete poles. Prestressed concrete poles use prestressed steel bars, which can save steel and improve crack resistance and service life. The application of grounding leads in concrete poles is very important, mainly to ensure the safety of electrical equipment.

[0003] In the prior art, such as in CN220020831U, a transformer core grounding lead fixing device is disclosed. It includes a fixed base, a connecting block, and a U-shaped grounding bolt. The top surface of the fixed base is fixedly connected to the bottom surface of the connecting block. The connecting block consists of two parts: a horizontal connecting block and a vertical connecting block. The bottom of the horizontal connecting block is fixed on the fixed base, and the bottom end of the vertical connecting block is fixed to one side of the top of the horizontal connecting block. A U-shaped bolt is installed at the top. The fixed base has a vertically penetrating wiring fixing pipe at the end away from the vertical connecting block. The horizontal connecting block has a wiring hole on the left side of the end away from the vertical connecting block and a threaded hole on the front side. The threaded hole extends into the wiring hole.

[0004] Although the aforementioned patent has a simple structure, is easy to process, and has low cost, and can effectively fix the grounding lead and prevent it from coming loose from the wiring hole due to the vibration of the transformer during operation, it still requires the use of various tools for installation and fixation, which still leads to inconvenience in operation. The grounding lead often has multiple strands connected, and the multiple strands cannot be bundled and managed, causing the lead to shake or entangle. Therefore, in order to solve the above problems, a ring concrete pole grounding lead fixing structure with self-locking buckle is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as the need for various tools for installation and fixing of grounding leads, which still leads to operational inconvenience, and the inability to manage multiple strands of grounding leads in a bundle, resulting in problems such as shaking or tangling of the leads, this utility model proposes a ring-shaped concrete pole grounding lead fixing structure with a self-locking buckle.

[0006] The technical solution adopted by this utility model to solve its technical problem is: the ring concrete pole grounding lead fixing structure with self-locking buckle of this utility model includes a fixing plate; a connecting cylinder is fixedly connected to one side of the fixing plate, and a threaded screw is rotatably connected to the surface of the fixing plate and inside the connecting cylinder; a bearing is sleeved inside one end of the connecting cylinder, and a knob is fixedly connected to one end of the threaded screw through the inside of the bearing.

[0007] The threaded screw has a threaded ring threadedly connected to its surface and inside the connecting cylinder. Connecting blocks are fixedly connected to both sides of the threaded ring in an axially symmetrical manner. Several elastic rubber teeth are provided on one side of the connecting block.

[0008] A connecting plate and B connecting plate are fixedly connected to both sides of the fixed plate respectively. A slot is opened inside one end of the A connecting plate, and an insert plate is provided at one end of the B connecting plate. The size of the insert plate and the slot are compatible.

[0009] Preferably, the A connecting plate and the B connecting plate are symmetrically distributed on both sides of the fixed plate, wherein the opening direction of the slot inside one end of the A connecting plate is consistent with the orientation of the insert plate at one end of the B connecting plate.

[0010] Preferably, both the A connecting plate and the insert plate have threaded holes on their surfaces, and fixing bolts are installed inside the threaded holes.

[0011] Preferably, the connecting cylinder has symmetrically arranged wire grooves on both sides, and a grounding lead is sleeved inside the wire groove.

[0012] Preferably, the inner wall of the connecting cylinder is provided with two limiting strips, which are distributed symmetrically along an axis.

[0013] Preferably, each of the connecting blocks has a sliding groove on one side, and the interior of the sliding groove is slidably connected to the surfaces of the two limiting strips.

[0014] The advantages of this utility model are:

[0015] 1. This utility model drives the threaded screw to rotate by rotating the knob, which in turn drives the threaded ring and connecting block to slide along the limiting strip. This causes the elastic rubber teeth to radially press the grounding lead wire. The serrated structure of the elastic rubber teeth enhances the friction with the lead wire and improves the tensile strength. The sliding cooperation between the limiting strip and the slide groove ensures the linear movement of the threaded ring, avoids loosening due to uneven load, and improves the wind vibration resistance. The lead wire can be fixed by hand rotation without tools, which improves the installation efficiency and solves the problem of time-consuming traditional bolt tightening.

[0016] 2. This utility model allows multiple grounding leads to be inserted simultaneously through symmetrically opened wire slots on both sides of the connecting cylinder. The elastic rubber teeth adapt to different wire diameters, preventing the leads from crossing and tangling, and improving the neatness of the arrangement. The A connecting plate and the B connecting plate are inserted into the slot through the insert plate and locked with the fixing bolts. Multiple fixing plates can be connected in series to accommodate multiple grounding leads and expand the installation range. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, the grounding lead fixing structure of the annular concrete pole with self-locking buckle includes a fixing plate 1; a connecting cylinder 2 is fixedly connected to one side of the fixing plate 1; a threaded rod 3 is rotatably connected to the surface of the fixing plate 1 and inside the connecting cylinder 2; a bearing 4 is sleeved inside one end of the connecting cylinder 2; a knob 5 is fixedly connected to one end of the threaded rod 3 through the inside of the bearing 4; a threaded ring 301 is threadedly connected to the surface of the threaded rod 3 and inside the connecting cylinder 2; connecting blocks 302 are fixedly connected to both sides of the threaded ring 301 in an axially symmetrical manner; and several elastic rubber teeth 303 are provided on one side of the connecting block 302.

[0025] During operation, rotating knob 5 drives the threaded screw 3 to rotate, causing the threaded ring 301 to slide along the limiting strip 10. The connecting block 302 pushes the elastic rubber teeth 303 to radially press the grounding lead 9. This process can be done by hand without tools, significantly reducing the time required for single-point lead fixing and greatly improving efficiency compared to traditional bolt fixing. The serrated structure of the elastic rubber teeth 303 enhances friction and increases tensile strength. The limiting strip 10 on the inner side of the connecting cylinder 2 and the sliding groove 11 of the connecting block 302 form a two-way linear guide rail, ensuring that the threaded ring 301 moves linearly without deviation. This design ensures that the clamping force is evenly distributed, avoiding lead damage caused by stress concentration on one side and improving wind resistance.

[0026] Furthermore, A connecting plate 101 and B connecting plate 102 are fixedly connected to both sides of the fixed plate 1, respectively. A slot 103 is opened inside one end of A connecting plate 101, and a plug plate 104 is provided at one end of B connecting plate 102. The size of plug plate 104 and slot 103 are matched. A connecting plate 101 and B connecting plate 102 are symmetrically distributed on both sides of the fixed plate 1. The opening direction of the slot 103 inside one end of A connecting plate 101 is consistent with the orientation of the plug plate 104 at one end of B connecting plate 102. Threaded holes 6 are opened on the surface of both A connecting plate 101 and plug plate 104. Fixing bolts 7 are provided inside the threaded holes 6.

[0027] During operation, the A connecting plate 101 and B connecting plate 102, which are symmetrically distributed on both sides of the fixed plate 1, are designed for plugging in. The plug plate 104 matches the slot 103, and multiple fixed plates 1 can be connected in series to form a row. The wire groove 8 of a single fixed plate 1 can constrain a small number of grounding leads 9. After the row is expanded, the management capacity of grounding leads 9 increases linearly, realizing the upgrade from "single-point fixing to multi-row centralized constraint", solving the pain point of traditional solutions being unable to centrally manage multiple leads, and improving the layout density.

[0028] Furthermore, the two sides of the connecting cylinder 2 are symmetrically provided with wire grooves 8, and a grounding lead 9 is sleeved inside the wire grooves 8;

[0029] During operation, the symmetrical opening design of the wire groove 8 allows grounding leads 9 of different diameters to be inserted simultaneously, and the elastic rubber teeth 303 automatically deform and engage according to the thickness of the lead.

[0030] Furthermore, the inner wall of the connecting cylinder 2 is provided with two limiting strips 10, which are symmetrically distributed along the axis. Each side of the connecting block 302 is provided with a sliding groove 11, and the interior of the sliding groove 11 is slidably connected to the surface of the two limiting strips 10.

[0031] During operation, the limiting strip 10 on the inner side of the connecting cylinder 2 and the sliding groove 11 of the connecting block 302 form a two-way linear guide rail, ensuring that the threaded ring 301 moves linearly without deviation. This design makes the clamping force evenly distributed, avoids damage to the lead wire caused by stress concentration on one side, and improves the wind resistance performance.

[0032] Working principle: Align the A connecting plate 101 of multiple fixed plates 1 with the B connecting plate 102 of the adjacent fixed plate 1, insert the insert plate 104 into the slot 103 to form a ring or linear arrangement, and lock the threaded hole 6 with the fixing bolt 7 to ensure that the A connecting plate 101 and the B connecting plate 102 of the adjacent fixed plate 1 are tightly connected. Pass the multiple grounding leads 9 into the wire grooves 8 on both sides of the connecting cylinder 2 respectively, and arrange them parallel to the grooves to avoid crossing and tangling. Rotate the knob 5 clockwise, the threaded screw 3 rotates, and drives the threaded ring 301 to slide along the limit strip 10 towards the center of the connecting cylinder 2. The connecting block 302 pushes the elastic rubber teeth 303 to radially squeeze the grounding leads 9. The sawtooth structure bites the lead surface to form a self-locking. The rotation resistance of the knob 5 increases significantly, and the grounding leads 9 cannot be manually pulled out.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
