Description

Technical Field

[0001] This utility model relates to the field of outfitting technology, and in particular to a locking and anti-loosening outfitting component. Background Technology

[0002] Movable decking is extensively used inside ships, serving two main purposes: as passageways for personnel and as protective barriers to prevent accidental collisions with personnel and equipment. Some areas inside ships experience high personnel activity and have a high concentration of small equipment and piping accessories, making them prone to accidental collisions that can result in injuries or equipment damage. Therefore, movable decking is necessary around these small equipment and piping accessories to act as protective barriers.

[0003] When installing movable panels, bolts and nuts are usually used for connection. However, the vibration generated during equipment operation can cause the bolts and nuts to loosen. Loose bolts and nuts cannot effectively control the operation of the equipment, which brings great safety hazards. In addition, manual tightening of nuts increases maintenance costs. Furthermore, nuts are usually exposed to the outside, which makes them easy to get wet from rain or seawater and rust, reducing their service life. Utility Model Content

[0004] The present invention aims to solve, at least to some extent, one of the problems existing in the prior art. To this end, the present invention proposes a locking and anti-loosening outfitting component.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A locking and anti-loosening outfitting component includes a main bolt and a nut. The main bolt includes a threaded rod and a nut, and also includes a protective shell. After the nut is threadedly connected to the main bolt, the protective shell can cover the outside of the nut. A limiting structure is provided between the threaded rod and the protective shell to restrict the rotation of the protective shell. A locking bolt is threadedly connected to the outside of the protective shell. The locking bolt can pass through the protective shell and press against the side wall of the nut.

[0007] In some embodiments, the screw includes a threaded portion and a smooth portion. One end of the threaded portion is connected to a nut, and the other end is connected to the smooth portion. The limiting structure includes a vertical groove on the outer wall of the smooth portion. One end of the protective housing is provided with a through hole, and a limiting flange is provided on the inner wall of the through hole. The smooth portion passes through the through hole, and the limiting flange is provided in the vertical groove.

[0008] In some embodiments, an elastic element is provided between the nut and the protective housing, with one end of the elastic element abutting against the nut and the other end abutting against the protective housing.

[0009] In some embodiments, the elastic element includes an annular elastic washer, on which a plurality of elastic pieces are evenly distributed along the circumference. The annular elastic washer abuts against the inner wall of the protective housing, and the elastic pieces abut against the nut.

[0010] In some embodiments, an annular groove is provided on the inner wall of the protective housing, and the annular elastic gasket is disposed in the annular groove.

[0011] In some embodiments, the nut includes a coaxially arranged external hexagonal member and a cylindrical member, and the locking bolt abuts against the cylindrical member.

[0012] In some embodiments, anti-slip textures are provided at both ends of the nut.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During installation, after the nut and the main bolt are tightened together, the protective shell is then placed over the nut to protect it from rain or seawater and prevent it from rusting. In addition, the protective shell is limited by the limiting structure, and the nut is pressed by the locking bolt, which can securely fix the nut, resulting in good anti-loosening effect, stable structural strength, and strong practicality.

[0018] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0019] like Figures 1-4The locking and anti-loosening outfitting component shown includes a main bolt 1 and a nut 2. The main bolt 1 includes a screw 3 and a nut 4, and also includes a protective shell 5. After the nut 2 is threadedly connected to the main bolt 1, the protective shell 5 can cover the outside of the nut 2. A limiting structure is provided between the screw 3 and the protective shell 5. The limiting structure is used to restrict the rotation of the protective shell 5. A locking bolt 6 is threadedly connected to the outside of the protective shell 5. The locking bolt 6 can pass through the protective shell 5 and press against the side wall of the nut 2.

[0020] During installation, after the nut 2 is tightened into the threaded engagement of the main bolt 1, the protective shell 5 is then placed over the nut 2 to protect it from rain or seawater, preventing it from rusting. In addition, the protective shell 5 is limited by a limiting structure, and the nut 2 is pressed by a locking bolt 6, thus securing the nut 2 firmly. This provides good anti-loosening effect, stable structural strength, and strong practicality.

[0021] See Figures 2-4 As shown, the screw 3 includes a threaded portion 21 and a smooth portion 22. One end of the threaded portion 21 is connected to the nut 4, and the other end is connected to the smooth portion 22. The limiting structure includes a vertical groove 23 provided on the outer wall of the smooth portion 22. One end of the protective shell 5 is provided with a through hole 24. A limiting flange 25 is provided on the inner wall of the through hole 24. The smooth portion 22 passes through the through hole 24, and the limiting flange 25 is provided in the vertical groove 23. Thus, the protective shell 5 is limited by the cooperation of the limiting flange 25 and the vertical groove 23, preventing the protective shell 5 from rotating relative to the smooth portion 22. The structure is simple and easy to install.

[0022] Furthermore, an elastic element is provided between the nut 2 and the protective shell 5, with one end of the elastic element abutting against the nut 2 and the other end abutting against the protective shell 5.

[0023] Furthermore, the elastic element includes a circular elastic washer 41, and a plurality of elastic pieces 42 are evenly distributed along the circumference of the circular elastic washer 41. The circular elastic washer 41 abuts against the inner wall of the protective shell 5, and the elastic pieces 42 abut against the nut 2. The circular elastic washer 41 and the elastic pieces 42 are integrally stamped.

[0024] A circular groove 51 is provided on the inner wall of the protective shell 5, and the circular elastic pad 41 is provided in the circular groove 51, so as to facilitate the fixing of the elastic element.

[0025] See Figure 2 , Figure 4As shown, the nut 2 includes an external hexagonal piece 61 and a cylindrical piece 62 arranged coaxially, and the locking bolt 6 abuts against the cylindrical piece 62.

[0026] In this invention, anti-slip texture 71 is provided at both ends of the nut 2.

[0027] During installation, bolt 1 passes through plate 10 and is threadedly connected to nut 2. After nut 2 is tightened, an elastic element is installed inside the protective shell 5, with the annular elastic washer 41 of the elastic element placed in the annular groove 51, and then placed on the outside of nut 2. The smooth rod 22 passes through the through hole 24, and the limiting flange 25 is placed in the vertical sliding groove 23, with the elastic washer 42 abutting against nut 2 to press it down. Finally, the locking bolt 6 is tightened, pressing the cylindrical part 62 of nut 2 against the outer wall, thus firmly fixing nut 2 with good anti-loosening effect, stable structural strength, and strong practicality.
