Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and more specifically, to a locking nut. Background Technology

[0002] Nuts are widely used as fasteners for installing and fixing profiles. There are many types of nuts used in the current assembly process. The working principle of nuts is to achieve self-locking by using the friction between the nut and the bolt.

[0003] In the existing technology, nuts have a wide range of applications and are used in different environments. They are used in dusty and humid environments. With prolonged use, the connection is exposed to the outside world, which can easily lead to dust accumulation and rust. This can cause the nuts to rust and become stuck, making disassembly inconvenient. At the same time, vibration can cause the nuts to loosen between the nuts and the screw, affecting the tightness of the nut connection.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a locking nut to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A locking nut includes a nut body, a first protrusion at the bottom of the nut body, a sealing ring sleeved on the outer side of the first protrusion, a locking mechanism on the nut body, a second protrusion at the top of the nut body, a sleeve connected to the outer side of the second protrusion, a dust cover connected to the bottom of the sleeve, the dust cover covering the outer side of the nut body, a rotating handle at the top of the sleeve, and a disassembly head at the top of the dust cover.

[0008] Preferably, the first protrusion is arranged in a ring shape, and the sealing ring has a groove that matches the shape of the first protrusion.

[0009] Preferably, the second protrusion is provided in the form of a hollow column, and the outer side of the second protrusion is provided with external threads.

[0010] Preferably, the inner side of the sleeve is provided with an internal thread that matches the external thread, and the sleeve is threadedly connected to the second protrusion through the internal thread.

[0011] Preferably, the rotating handle is provided with anti-slip texture, and the disassembly head is located at the top center of the sleeve.

[0012] Preferably, the locking mechanism includes a connector, a threaded rod, a locking block, and a rubber pad. The two ends of the threaded rod are connected to the connector and the locking block, respectively. The connector has a slot that matches the disassembly head, and the rubber pad is disposed on one side of the locking block.

[0013] Preferably, the nut body is provided with a threaded hole that matches the threaded rod, and one end of the threaded hole is provided with a groove that matches the locking top block.

[0014] Preferably, the threaded rod passes through the threaded hole and is connected to the locking top block via a movable locking block. The locking top block has a slot on one side surface inside the nut body, and the rubber pad is attached to the slot of the locking top block.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By providing a sleeve, after connecting the locking nut and the screw, the sleeve is connected to the locking nut. The sleeve can shield and protect the screw, and the dust cover can protect the nut body, thus playing a role in dust and water protection.

[0017] 2. By incorporating a locking mechanism, when connecting the locking nut, the connecting head drives the threaded rod to rotate, causing the locking top block to contact the threaded part of the screw rod. The rubber pad then locks the locking nut in place, preventing loosening between the locking nut and the screw rod and improving the connection effect between them. Attached Figure Description
