Description

Technical Field

[0001] This utility model relates to the field of electric power iron accessories, specifically an anti-detachment electric power iron accessory. Background Technology

[0002] Transmission lines are usually secured to utility poles by crossarms, which are then secured to the poles by clamps. Clamps are commonly used to fasten equipment or guy ropes on utility poles.

[0003] In the prior art, such as in publication number CN214063473U, a fixing clamp for preventing detachment is disclosed. It includes a first clamp body, a second clamp body, and two threaded sleeves. Two bolt posts are fixedly connected to one end of one side of the top and one side of the first clamp body. A first threaded hole is formed on one side of each threaded sleeve, and the two bolt posts are threadedly connected to their corresponding first threaded holes. This invention achieves the clamping of the two clamps through the cooperation of the threaded sleeves and the bolt posts. The rotation of the threaded sleeves is restricted by the cooperation of the locking rod and the outer groove of the threaded sleeve, and the vertical movement of the locking rod is restricted by the threads, thereby preventing the clamps from loosening and improving their safety.

[0004] While the aforementioned patent achieves the effect of preventing the clamp from loosening through a multi-structure design of clamp rods and threaded sleeves, the structure is relatively complex, the operation is also relatively complicated, and the efficiency is low. At the same time, a single protection structure has the same risk and lacks multiple anti-detachment protection structures. Therefore, an anti-detachment electric iron accessory is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as complex structures, complicated operations, and low efficiency, and the lack of multiple anti-detachment protection structures, this invention proposes an anti-detachment electric iron accessory.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The anti-detachment electric iron accessory of this utility model includes an upper clamp and a lower clamp. Both ends of the upper clamp and the lower clamp are provided with mounting holes. A screw is threadedly connected inside the mounting hole. An anti-detachment component is fixedly connected to the top of the screw. A limit component is fixedly connected to the top surface of the anti-detachment component. An octagonal block is fixedly connected to the bottom end of the screw.

[0007] The anti-detachment component includes two clamping plates symmetrically fixedly connected to the top surface of the screw. A rotating block is rotatably connected to the side of the clamping plate. A plastic rod is fixedly connected to the bottom surface of the rotating block. A thin support structure is provided in the middle section of the plastic rod. The bottom end of the plastic rod is fixedly connected to the top surface of the screw.

[0008] The limiting component includes a screw block fixedly connected to the top surface of the clamping plate. A through limiting hole is opened on the side of the screw block. A limiting rod is inserted into the limiting hole. Both ends of the limiting rod are provided with insertion holes, and elastic inserts are inserted into the insertion holes.

[0009] Preferably, the rotating block and clamping plate of the anti-detachment component form a flip-able connection structure through a rotating shaft, and the thin support structure of the plastic rod is located in the region where the diameter of the middle section is reduced.

[0010] Preferably, the bottom surface of the screw block of the limiting assembly is vertically and fixedly connected to the top surface of the clamping plate, and the axis of the insertion hole of the limiting rod is set perpendicular to the length direction of the limiting rod.

[0011] Preferably, after the plastic rod breaks, the rotating block connected to its top end can be placed flat on the surface of the mounting hole, and the screw block forms a limiting structure that blocks the rotation of the screw when the rotating block is flat.

[0012] Preferably, after the elastic insert is inserted into the insertion hole of the limiting rod, its end forms an anti-dislodgement head with a diameter larger than the insertion hole, and the elastic insert is made of spring steel.

[0013] Preferably, the clamping plates are symmetrically arranged on both sides of the top surface of the screw, and the distance between the two clamping plates is less than the width of the screw block.

[0014] The advantages of this utility model are:

[0015] 1. This utility model uses a thin support structure design for the plastic rod in the anti-detachment component. After the screw is tightened to the correct position, turning the screw block will cause the plastic rod to break, allowing the rotating block to lie flat on the surface of the mounting hole to form a mechanical lock on the rotation of the screw. The operation is simple and quick, and the anti-detachment function is achieved through a one-time action, which significantly improves the installation efficiency.

[0016] 2. This utility model uses a limiting rod in the limiting component to pass through the limiting hole of the screw block and an elastic insert to form a secondary fixation. On the basis of preventing plastic rod breakage and detachment, a lateral limiting protection is superimposed. The double anti-detachment structure ensures the linkage locking effect between the clamp and the screw block, effectively reducing the risk of failure of a single anti-detachment mechanism and improving the long-term stability of electric iron accessories in vibration environment.

[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, an anti-detachment electric iron accessory includes an upper clamp 1 and a lower clamp 2. Both ends of the upper clamp 1 and the lower clamp 2 are provided with mounting holes. A screw 3 is threadedly connected inside the mounting holes. An anti-detachment component 4 is fixedly connected to the top of the screw 3. A limit component 5 is fixedly connected to the top surface of the anti-detachment component 4. An octagonal block 6 is fixedly connected to the bottom of the screw 3. The anti-detachment component 4 includes two clamping plates 41 symmetrically fixedly connected to the top surface of the screw 3. A rotating block 42 is rotatably connected to the side of the clamping plate 41. A plastic rod 43 is fixedly connected to the bottom surface of the rotating block 42. A thin support structure is provided in the middle section of the plastic rod 43. The bottom of the plastic rod 43 is fixedly connected to the top surface of the screw 3.

[0025] During operation, the screw 3 is rotated by the octagonal block 6 to make it threaded into the mounting holes of the upper clamp 1 and the lower clamp 2. When the top of the screw 3 protrudes from the top surface of the mounting hole, the screw block 51 of the anti-detachment component 4 is turned outward. The lever action causes the rotating block 42 to rotate around the axis of the clamp 41, which causes the thin support structure in the middle section of the plastic rod 43 to break. At this time, the rotating block 42 is placed flat on the surface of the mounting hole and forms a horizontal limiting surface with the screw block 51, preventing the screw 3 from rotating in the opposite direction, and completing the anti-detachment locking in one go.

[0026] Furthermore, the limiting component 5 includes a screw block 51 fixedly connected to the top surface of the clamping plate 41. A through limiting hole is opened on the side of the screw block 51. A limiting rod 52 is inserted into the limiting hole. Both ends of the limiting rod 52 are provided with insertion holes. An elastic insert 53 is inserted into the insertion holes.

[0027] During operation, after the plastic rod 43 breaks, the limiting rod 52 is inserted laterally into the limiting hole on the side of the screw block 51. Then, the spring steel elastic insert 53 with elastic deformation capability is inserted through the insertion holes at both ends of the limiting rod 52. The end of the elastic insert 53 expands to form an anti-dislodgement head with a diameter larger than the insertion hole. The limiting rod 52 is clamped by elastic rebound to achieve axial fixation. The limiting rod 52 passes through the screw blocks 51 on both sides to form a lateral rigid constraint, doubly locking the relative position of the clamping plate 41 and the screw block 51, and strengthening the anti-reverse effect.

[0028] Furthermore, the rotating block 42 of the anti-detachment component 4 and the clamping plate 41 form a flip-able connection structure through a rotating shaft, and the thin support structure of the plastic rod 43 is located in the middle section with a reduced diameter.

[0029] During operation, the rotating block 42 is rotated around the axis by turning the screw block 51, causing the diameter reduction area of ​​the middle section of the plastic rod 43 to be subjected to concentrated stress and break. This thin support structure precisely controls the breakage position, ensuring that the rotating block 42 is completely in contact with the surface of the mounting hole after it is rotated. This design achieves the rapid switching of the rotating block 42 to the anti-loosening state through directional fracture. No tools are required during operation and the fracture force is controllable. This simplifies the installation steps and avoids damage to the screw rod 3 due to excessive force. At the same time, the remaining part of the plastic rod 43 after the thin support structure breaks is still fixed to the top surface of the screw rod 3, preventing the rotating block 42 from falling off and being lost, improving the reliability of anti-loosening and reducing maintenance costs.

[0030] Furthermore, the bottom surface of the screw block 51 of the limiting component 5 is vertically and fixedly connected to the top surface of the clamping plate 41, and the axis of the insertion hole of the limiting rod 52 is set perpendicular to the length direction of the limiting rod 52.

[0031] During operation, the bottom surface of the screw block 51 is vertically fixed to the top surface of the clamping plate 41, ensuring that the axis of the limiting hole of the screw block 51 is orthogonal to the extension direction of the clamping plate 41. When the limiting rod 52 is inserted into the elastic insert 53 along the insertion hole axis perpendicular to its own length direction, the spring steel material of the elastic insert 53 causes it to undergo radial compression during insertion. After passing through the insertion hole, it returns to its original shape to form an end anti-detachment head. This vertical insertion method makes the limiting rod 52 and the screw block 51 form a cross-locking structure. This structure effectively restricts the displacement of the screw block 51 and the clamping plate 41 through the double constraint in the orthogonal direction. The design that the insertion hole axis is perpendicular to the length direction of the limiting rod 52 decouples the insertion and extraction direction of the elastic insert 53 from the force direction of the limiting rod 52, avoiding the insertion strip from loosening under vibration. At the same time, the vertically fixed screw block 51 provides a precise alignment reference for the limiting rod 52, ensuring the rapid installation and long-term stability of the secondary anti-detachment component.

[0032] Working principle: The octagonal block 6 drives the screw 3 to screw into the mounting holes of the upper clamp 1 and the lower clamp 2. When the top of the screw 3 protrudes from the top surface of the mounting hole, the screw block 51 of the anti-detachment component 4 is turned, causing the rotating block 42 to rotate around the axis of the clamping plate 41. This causes the thin support structure in the middle section of the plastic rod 43 to break under torsional force. After the breakage, the rotating block 42 lies flat on the surface of the mounting hole and forms a horizontal blocking surface with the screw block 51, preventing the octagonal block 6 from rotating the screw 3 in the opposite direction, thus achieving the initial anti-detachment locking. Subsequently, the limiting rod 52 is inserted laterally into the limiting hole of the screw block 51, and the spring steel... The elastic insert 53 is inserted along the insertion axis perpendicular to the length direction of the limiting rod 52. The end of the elastic insert 53 expands to form an anti-dislodgement head, which restricts the axial displacement of the limiting rod 52. At the same time, the limiting rod 52 passes through the screw blocks 51 on both sides to form a lateral rigid constraint, thus locking the relative position of the anti-dislodgement component 4 and the limiting component 5. This prevents the screw 3 from reversing due to vibration or external force. Finally, the long-term anti-dislodgement stability of the electric iron accessory is ensured through the combined effect of the one-time mechanical locking caused by the breakage of the plastic rod 43 and the secondary rigid fixation of the insertion of the limiting rod 52.

[0033] The above description is merely a preferred embodiment of the present utility model and is 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.
