Description

Technical Field

[0001] This utility model relates to the field of nut assemblies, specifically a shock-resistant and anti-loosening nut assembly. Background Technology

[0002] A nut, also known as a bolt, is a fastening tool with a central hole and threads on the inside. It is often used in conjunction with a matching screw to secure mating parts. Nuts are parts that are screwed together with bolts or threaded rods to achieve a fastening effect. They are essential components in all manufacturing machinery. Based on their material, nuts are classified into several types, including carbon steel, stainless steel, and non-ferrous metals.

[0003] For example, the authorized patent with publication number CN211423131U (External Conical Self-Locking Nut Assembly) includes a fixed nut assembly and a locking nut assembly; the fixed nut assembly includes a fixed nut and an external conical locking nut ring, and the locking nut assembly includes a locking nut body and an external conical locking nut cap; the external conical locking nut ring is disposed on the fixed nut assembly, and the locking nut body is divided into a fixed thread portion and an installation thread portion, the installation thread portion being threaded onto the external conical locking nut ring to facilitate locking the fixed nut assembly; the external conical locking nut cap is disposed on the locking nut body, and the external conical locking nut cap has multiple openings evenly distributed; the inner diameter of the internal thread of the external conical locking nut cap is smaller than the inner diameter of the internal thread of the fixed thread portion. The external conical self-locking nut assembly provided by this utility model adopts a double locking method to effectively solve the problem of safety hazards caused by nut loosening due to high-frequency vibration;

[0004] The nuts in the aforementioned prior art cannot be double-locked during the installation and fixing process, making them prone to loosening after installation vibration, resulting in insufficient firmness. Furthermore, the nuts cannot be installed from the inside or outside, and the installation and fixing method is limited. Utility Model Content

[0005] The purpose of this utility model is to provide a shock-resistant and anti-loosening nut assembly to solve the problems mentioned in the background art, such as the inability to double-lock the nut during installation, the nut being prone to loosening after installation vibration, insufficient firmness, and the inability to switch between internal and external installation, resulting in a single installation and fixing method.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-resistant and anti-loosening nut assembly, comprising a screw head, a nut, a hidden groove, an adjusting head, and a locking head. The nut has screw heads at both ends, multiple locking heads on the inner side of the nut, external threads on the outer side of the screw head, an installation port in the middle of the screw head, and a second internal thread and a first internal thread on the inner sidewalls of the screw head and the nut, respectively.

[0007] In a further embodiment, the outer side of the nut is provided with a plurality of hidden grooves, and an adjustment head is provided in the hidden grooves.

[0008] In a further embodiment, the nut has an internal thread on its inner side, and the adjusting head is connected to the internal thread for threaded transmission.

[0009] In a further embodiment, the screw head has external threads on its outer side, the nut has a hexagonal structure, and the screw head and nut are an integral structure.

[0010] In a further embodiment, there are a total of six hidden grooves, and the six hidden grooves are respectively located on the six edges of the nut.

[0011] In a further embodiment, the nut is fixedly connected to the screw thread via a first internal thread and a second internal thread, and is also fixedly installed via the screw head and the threaded sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The nut of this utility model has a first internal thread on the inner side, and a screw head is provided at both ends of the nut. A second internal thread is provided on the inner side of the screw head. The first and second internal threads facilitate the threaded fixing and installation of the screw rod. A screw head is provided at both ends of the nut, and an external thread is provided on the outer side of the screw head. The external thread facilitates the installation of the screw rod.

[0014] 2. The nut of this utility model is provided with a hidden groove, an adjusting head is provided in the hidden groove, and a locking head is provided at the end of the adjusting head. The locking head can lock and fix the screw after installation, which can improve the stability of the nut fixation and provide vibration protection. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a shock-resistant and anti-loosening nut assembly, comprising a screw head 1, a nut 2, a hidden groove 3, an adjusting head 4, and a locking head 5. The nut 2 has screw heads 1 at both ends, multiple locking heads 5 on its inner side, external threads on the outer side of the screw head 1, and an installation port 7 in the middle of the screw head 1. The inner walls of the screw head 1 and the nut 2 are respectively provided with a second internal thread 8 and a first internal thread 6. The screw head 1 allows the nut 2 to be threadedly fixed to a threaded sleeve, the locking head 5 strengthens and locks the nut 2, and the installation port 7, the second internal thread 8, and the first internal thread 6 facilitate the threaded fixing of the screw rod.

[0022] The outer side of the nut 2 has multiple hidden grooves 3, each containing an adjusting head 4. The adjusting head 4 can be concealed within the hidden grooves 3, and it controls the locking head 5 to tighten and secure the screw. The inner side of the nut 2 has internal threads, and the adjusting head 4 is threadedly connected to these threads. This design facilitates the control of the locking head 5 by the adjusting head 4. There are six hidden grooves 3 in total, located on the six edges of the nut 2, allowing the adjusting head 4 to be concealed within them.

[0023] The screw head 1 has external threads on its outer side, and the nut 2 has a hexagonal structure. The screw head 1 and the nut 2 are integrated into one piece, and the screw head 1 facilitates the threaded installation of the nut 2. The nut 2 is threadedly connected to the screw rod through the first internal thread 6 and the second internal thread 8, and is also threadedly installed on the threaded sleeve through the screw head 1.

[0024] Working principle: In use, the nut 2 can be installed and fixed with the threaded sleeve through the screw head 1. The screw rod and nut 2 can be threaded and fixed through the first internal thread 6 and the second internal thread 8. The hidden groove 3 facilitates the concealment and protection of the adjustment head 4. The adjustment head 4 can be manually controlled to rotate the locking head 5, so that the locking head 5 can lock and fix the installed screw rod, which can prevent vibration and loosening.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
