Description

Technical Field

[0001] This utility model relates to the field of anchor bolt technology, specifically an anti-loosening structure for anchor bolt nuts used in electromechanical equipment. Background Technology

[0002] Anchor bolt connection is a mechanical fastening method that fixes mechanical equipment, steel structures, building components, etc. to concrete foundations, ground or walls. Anchor bolts are usually embedded in the concrete foundation at one end and protrude from the foundation at the other end. The connected parts (such as equipment bases, steel column base plates, brackets, etc.) are fastened by accessories such as nuts and washers, thereby achieving a rigid or semi-rigid connection between the components and the foundation, transmitting loads (such as vertical force, horizontal force, torque, etc.) and restricting component displacement.

[0003] An investigation revealed that a utility model patent (publication number: CN220248587U) discloses a non-loosening anchor bolt installation structure, comprising a reinforced concrete foundation and anchor bolt bodies. Two anchor bolt bodies are symmetrically embedded at their lower ends within the reinforced concrete foundation on both sides. This utility model uses an anti-loosening pressure cover to install a reverse-threaded rod in a reverse-threaded groove, pressing the anti-loosening pressure cover down on the nut. This reverse-threaded installation increases the nut's stability. Simultaneously, the bottom end of the reverse-threaded rod breaks the glue reservoir, allowing the screw glue to flow through a guide hole between the nut and the anchor bolt, fixing them together. This improves the nut's stability when installed on the anchor bolt, preventing loosening due to vibration and thus enhancing the overall stability of railway sound barrier installation.

[0004] While the aforementioned patent improves the stability of anchor bolts after installation through the design of components such as the anchor bolt body, anti-loosening cover, and reverse threaded rod, and enhances the bonding force between multiple nuts with glue to prevent loosening during use, the adhesive properties of the glue may decrease with increasing temperature or rain. This could lead to loosening of the nuts due to vibration during use, which is detrimental to improving the installation stability of the equipment.

[0005] Therefore, this utility model provides an anti-loosening structure for anchor bolts and nuts of electromechanical equipment to solve the above problems. Utility Model Content

The outer wall of the fastening bolt is threadedly connected to a fastening nut B above the serrated rings.

[0017] 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 protection scope of the present utility model.

[0018] This utility model provides an anti-loosening structure for anchor bolts and nuts of electromechanical equipment, such as... Figures 1-5 As shown, the anti-loosening structure for anchor bolts and nuts of electromechanical equipment includes a pad 1 and a fastening assembly. The top end of the pad 1 is threadedly connected to an equipment plate 3 by a fastening bolt 2. The fastening assembly includes an A fastening nut 4 threaded to the outer wall of the fastening bolt 2. The upper top of the A fastening nut 4 is threaded to a meshing washer 6 via a meshing bolt 5. A serrated ring 7 is fixedly connected to the upper top of the meshing washer 6. There are multiple serrated rings 7, and the multiple serrated rings 7 are arranged circumferentially along the center of the A fastening nut 4. The outer wall of the fastening bolt 2 is threaded to a B fastening nut 8 above the serrated rings 7. The lower bottom end of the B fastening nut 8 engages with the serrated ring 7 via a serrated seat 9.

[0019] The top of the fastening nut 8 is fixedly connected to a rigid washer 11 by a damping spring 10. The outer wall of the rigid washer 11 is coated with an anti-rust coating.

[0020] The outer wall of the fastening bolt 2 is slidably fitted with a rubber pad 12 at the top of the rigid washer 11, and the outer wall of the rubber pad 12 is coated with lubricant.

[0021] Specifically, the pad 1 improves the tightness of the connection with the external environment, further enhancing the installation stability of the electromechanical equipment and maintaining its operational stability. The fastening components, through their mutual cooperation, improve the stability of the anchor bolts and nuts after installation, preventing the nuts from loosening due to vibration. The A-type fastening nut 4 can fit against the equipment plate 3 after rotation, and the interlocking washer 6 and its internal interlocking bolt 5 provide a stable connection with the A-type fastening nut 4. Furthermore, after installation, the top of the interlocking washer 6... Multiple serrated rings 7 engage with multiple serrated seats 9 at the bottom of the B fastening nut 8. Through this engagement, the serrated teeth collide with each other when subjected to vibration, reducing the impact of vibration on the nut and preventing it from rotating due to vibration. The damping spring 10 at the top of the B fastening nut 8, together with the rigid washer 11, can alleviate the influence of gravity on the nut, preventing the nuts from deforming due to pressure. The rigid washer 11 and multiple rubber pads 12 work together to improve the locking effect of the nut through the soft material of the rubber pads 12, further improving the tightness of the installation.

[0022] The outer wall of the fastening bolt 2 is provided with a reverse thread 13 above the rubber pad 12. The outer wall of the reverse thread 13 is threaded with a reverse nut 14, and the outer wall of the reverse nut 14 is coated with an anti-corrosion coating.

[0023] The end of the fastening bolt 2 is movably fitted with a rust-proof sleeve 15 above the reverse nut 14, and the inner wall of the rust-proof sleeve 15 abuts against the outer wall of the reverse nut 14.

[0024] Specifically, the reverse thread 13 on the outer wall of the fastening bolt 2 can be used in conjunction with the reverse nut 14. The nuts in different directions work together to prevent the nuts from loosening when subjected to intense vibration. The anti-corrosion coating on the outer wall of the reverse nut 14 can improve its corrosion resistance, prevent external environmental erosion, and further improve its durability.

[0025] The bottom end of the pad 1 is provided with a reserved groove 16, and there are multiple reserved grooves 16.

[0026] The inner wall of the reserved groove 16 is fixedly connected with a meshing joint 17, and there are several meshing joints 17.

[0027] Specifically, the multiple pre-reserved grooves 16 at the bottom of the pad 1 can improve the connection with the concrete during concrete pouring. The multiple interlocking joints 17 inside the pad can increase the tightness of the connection with the concrete by increasing the number of contact surfaces, thereby further improving the stability of the equipment after installation.
