Description

Technical Field

[0001] This utility model relates to the field of heavy-duty connector technology, specifically a heavy-duty connector grounding plate and a locking bolt. Background Technology

[0002] Heavy-duty connectors play a crucial role in industrial production and the connection of various electrical equipment, and the stable connection of their grounding plates is indispensable for ensuring the safe operation of equipment. Traditional heavy-duty connector grounding plates typically use a connection method where the grounding plate body is connected with a locking bolt and nut (as in application number [number missing]). However, in actual use, due to factors such as vibration, temperature changes, and mechanical stress generated during equipment operation, the locking bolt and nut are prone to loosening. Once loosened, the connection stability of the grounding plate will be affected, potentially leading to poor grounding of electrical equipment, causing safety hazards such as leakage and short circuits, and in severe cases, even damaging the equipment and affecting normal production. Existing solutions are either ineffective or complex and costly. Therefore, there is an urgent need for a new technical solution to address the loosening problem between the locking bolt and nut, in order to improve the connection reliability and stability of heavy-duty connector grounding plates. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a heavy-duty connector grounding plate and a locking bolt.

[0004] The technical solution adopted by this utility model is: a heavy-duty connector grounding plate, including a grounding plate body and a locking bolt connected to the grounding plate body. At least one thread of the locking bolt is provided with an anti-loosening structure, which is composed of a concave surface on one side of the thread and a convex surface on the other side of the thread.

[0005] Furthermore, the concave surface has an arc-shaped structure.

[0006] Furthermore, the maximum depth of the concave surface is 1 / 3 to 1 / 4 of the maximum thickness of the thread.

[0007] Furthermore, the maximum height of the convex surface is 1 / 3 to 1 / 4 of the maximum thickness of the thread.

[0008] Furthermore, the anti-loosening structure consists of two parts, which are disposed on the two turns of thread located near the screw head.

[0009] Furthermore, the concave surfaces of the two anti-loosening structures are positioned opposite each other on adjacent threads.

[0010] This application also provides a locking bolt, wherein at least one thread of the locking bolt is provided with an anti-loosening structure, the anti-loosening structure being composed of a concave surface on one side of the thread and a convex surface raised on the other side of the thread.

[0011] The beneficial effects of this utility model are:

[0012] First, by incorporating a unique anti-loosening structure on the threads of the locking bolt, consisting of a concave surface on one side of the thread and a convex surface on the other, loosening between the locking bolt and the nut can be effectively prevented. This design greatly enhances the stability of the grounding connection, enabling electrical equipment to operate reliably even under complex conditions such as vibration, temperature changes, and mechanical stress.

[0013] Secondly, stable and reliable connections reduce the probability of equipment failure due to looseness, lowering maintenance costs and downtime. For industrial production, this improves efficiency, reduces economic losses from equipment repairs, and creates greater economic benefits for businesses.

[0014] Furthermore, the anti-loosening structure is ingeniously and simply designed, requiring no additional complicated installation tools or procedures. Without increasing costs excessively, it significantly improves the performance of the heavy-duty connector grounding plate, making it highly practical and worthy of widespread application.

[0015] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0022] This utility model provides a heavy-duty connector grounding plate.

[0023] In this embodiment, refer to Figure 1-3 The heavy-duty connector grounding plate includes a grounding plate body 1 and a locking bolt 2 connected to the grounding plate body 1. At least one thread of the locking bolt 2 is provided with an anti-loosening structure, which is composed of a concave surface 3 on one side of the thread and a convex surface 4 on the other side of the thread.

[0024] In the above technical solution, an anti-loosening structure composed of a concave surface on one side and a convex surface on the other side is provided on the thread of the locking bolt. This can effectively prevent the locking bolt and nut from loosening, improve the connection stability of the grounding plate, ensure the safe operation of the equipment, and avoid potential hazards such as leakage and short circuit.

[0025] The anti-loosening structure uses a combination of concave and convex surfaces, which provides good anti-loosening effect and is simple in structure and easy to process.

[0026] Specifically, the concave surface has an arc-shaped structure.

[0027] In this embodiment, the concave surface adopts an arc-shaped structure. Compared with other shapes, the arc-shaped structure can distribute pressure more evenly when subjected to force. This further enhances the anti-loosening effect and, under conditions such as vibration, can better resist the loosening tendency caused by uneven force, thus helping to maintain the long-term stability of the grounding plate connection.

[0028] Specifically, the maximum depth of the concave surface is 1 / 3 to 1 / 4 of the maximum thickness of the thread.

[0029] In this embodiment, the maximum depth of the concave surface is limited to 1 / 3 to 1 / 4 of the maximum thickness of the thread. This precise dimensional range design enables a good anti-loosening function.

[0030] Specifically, the maximum height of the convex surface is 1 / 3 to 1 / 4 of the maximum thickness of the thread.

[0031] In this embodiment, the maximum depth of the convex surface is limited to 1 / 3 to 1 / 4 of the maximum thread thickness. This precise dimensional range design enables a good anti-loosening function.

[0032] Specifically, there are two anti-loosening structures, which are located on the two turns of thread near the screw head.

[0033] In this embodiment, two anti-loosening structures are provided on the two turns of thread near the screw head to ensure the anti-loosening effect.

[0034] Specifically, the concave surfaces of the two anti-loosening structures are positioned opposite each other on adjacent threads.

[0035] In this embodiment, the concave surfaces of the two anti-loosening structures are arranged opposite each other on adjacent threads. This opposite arrangement allows the anti-loosening structures on both turns of the thread to function simultaneously when the nut is tightened, forming a stronger constraint mechanism and further enhancing the anti-loosening effect.

[0036] This application also provides a locking bolt, wherein at least one thread of the locking bolt 2 is provided with an anti-loosening structure, the anti-loosening structure being composed of a concave surface 3 on one side of the thread and a convex surface 4 on the other side of the thread.

[0037] Locking bolt 2 boasts excellent versatility and anti-loosening performance. Besides being compatible with heavy-duty connector grounding plates, it can also be used in other applications requiring bolted connections. For example, in the construction industry, it's used for steel structure connections, effectively preventing bolt loosening caused by building vibrations or long-term stress, ensuring the stability of the building structure. In automotive manufacturing, it's suitable for connections in critical components such as engines and chassis, resisting severe vibrations during vehicle operation and improving vehicle safety and reliability. Furthermore, in the assembly of various industrial machinery and electronic equipment, its special anti-loosening structure can adapt to various nut types, significantly improving the anti-loosening ability of the connection without changing the nut specifications, thereby enhancing the overall operational safety and reliability of the equipment.

[0038] Please note to all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
