Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a buckle double-head anti-loosening spring nut assembly. Background Art

[0002] Spring nut assemblies are fasteners upgraded from bolts and nuts. They have a certain rebound effect, which allows the two connecting parts to have a certain buffering capacity after connection. At the same time, they have high stability and are often used in industries such as industry, transportation, electronics, photovoltaics, and new energy. However, existing spring nut assemblies are prone to loosening or even falling due to vibration or shaking of objects during use, causing production accidents.

[0003] Based on the above technical problems, the applicant proposes a buckle double-ended anti-loosening spring nut assembly. Utility Model Content

[0004] The purpose of the utility model is to provide a buckle double-head anti-loosening spring nut assembly to solve the technical problems mentioned in the background technology. The purpose of the utility model is achieved through the following technical solutions:

[0005] A double-ended anti-loosening spring nut assembly comprises a nut body, which is a hexagonal prism structure. A cylindrical boss is fixed to one end of the nut body, and a compression spring is sleeved on the outer side of the boss. A threaded hole is opened in the center of the nut body, and the threaded hole passes through the nut body and the boss. An outer shell is arranged on the outer side of the nut body, and the outer shell comprises a hexagonal shell and a screw thread fixed to one end of the shell, and the screw thread is located at the end away from the compression spring.

[0006] Furthermore, the thickness of the boss is greater than the length of the compression spring after compression.

[0007] Furthermore, an end of the boss away from the nut body is provided with an anti-slip groove.

[0008] Furthermore, the thickness of the shell is smaller than the sum of the thicknesses of the nut body and the boss.

[0009] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0010] By arranging a compression spring on one end of the nut body, the nut body can be cushioned and the impact of equipment vibration on the nut body can be reduced. At the same time, a screw thread is arranged on the other end of the nut body to further prevent the nut body from loosening through the engagement of the screw thread with the external thread on the bolt, thereby improving the reliability of the spring nut connection and ensuring the safe and stable operation of the equipment.

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1-4 A buckle double-headed anti-loosening spring nut assembly shown includes a nut body 1, a compression spring 2 and a shell 3. The nut body 1 is a hexagonal prism structure, and a cylindrical boss 11 is fixed to the lower end of the nut body 1. The compression spring 2 is sleeved on the outside of the boss 11, and the upper end of the compression spring 2 abuts against the lower end of the nut body 1. A threaded hole 12 is provided in the center of the nut body 1, and the threaded hole 12 passes through the nut body 1 and the boss 11. Among them, the thickness of the boss 11 is greater than the length of the compression spring 2 after compression, and an anti-slip groove 111 is provided on the end of the boss 11 away from the nut body 1. When the nut body 1 is locked, the compression spring 2 is compressed by the nut body 1 and the connecting piece so that the boss 11 abuts against the connecting piece to prevent the nut body 1 from rotating.

[0019] like Figure 1-4As shown, the shell 3 is sleeved on the outside of the nut body 1, and the shell 3 includes a shell 31 and a screw thread 32 fixed on the shell 31. The shell 31 is a hexagonal structure with an open lower end. A through hole matching the threaded hole 12 is opened at the center of the top of the shell 31. Two screw threads 32 are symmetrically fixed at the through hole. The shell 3 is sleeved on the outside of the nut body 1 from top to bottom. Among them, the shell 3 is stamped from a metal sheet, and the thickness of the shell 3 is less than the sum of the thicknesses of the nut body 1 and the boss 11 to avoid affecting the locking of the nut body 1.

[0020] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0021] By arranging a compression spring on one end of the nut body, the nut body can be cushioned and the impact of equipment vibration on the nut body can be reduced. At the same time, a screw thread is arranged on the other end of the nut body to further prevent the nut body from loosening through the engagement of the screw thread with the external thread on the bolt, thereby improving the reliability of the spring nut connection and ensuring the safe and stable operation of the equipment.

[0022] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
