Description

Technical Field

[0001] This utility model relates to the field of nut technology, specifically a hexagonal flange nut with an anti-reverse structure. Background Technology

[0002] In patent application CN221879942U, a nut is included. A bolt is threaded onto the inner wall of the nut. A circular plate is slidably connected to the inner wall of the nut. A movable column is fixedly connected to the bottom end of the circular plate. A conical ring is fixedly connected to the bottom end of the movable column. A limit assembly is fixedly connected to the front end of the nut. A movable plate is slidably connected to the inner wall of the nut. A rubber pad is fixedly connected to the outer wall of the movable plate. The limit assembly includes a limit block. The outer wall of the limit block is fixedly connected to the front end of the nut. A positioning plate is elastically connected to the inner wall of the limit block via a connecting spring. A plug-in column is fixedly connected to the center of the positioning plate. A plug-in hole is formed on the outer wall of the conical ring. In this invention, releasing the limit and moving the conical ring causes the three sets of movable plates to move inward, causing the rubber pad to press against the bolt thread surface. The limit assembly limits this state, thereby preventing the bolt and nut from retracting.

[0003] In the aforementioned patents or prior art, the locking method for nuts mostly relies on applying pressure to the bottom of the nut to increase friction and achieve the anti-loosening effect. Some anti-loosening nuts use rubber pads to increase friction, but after long-term use in extreme environments such as high-frequency vibration, loosening may still occur. Utility Model Content

[0004] The purpose of this invention is to provide a hexagonal flange nut with an anti-loosening structure to solve the problem of easy loosening in extreme environments mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hexagonal flange nut with a backstop structure, comprising a nut, two split threaded sleeves on the top of the nut, the two split threaded sleeves being fixedly connected to the nut, and a flange being fixedly connected to the bottom of the nut.

[0006] Furthermore, the top of the nut is provided with two anti-slip pads, which are fixedly connected to the nut, and the two split threaded sleeves are adapted to the two anti-slip pads.

[0007] Furthermore, the nut is provided with an iron hoop at the top, which is adapted to the anti-slip pad.

[0008] Furthermore, a locking bolt is provided on one side of the iron hoop, and the locking bolt is compatible with the iron hoop.

[0009] Furthermore, the iron hoop has several threaded grooves.

[0010] Furthermore, the anti-slip mat is made of rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the hexagonal flange nut with anti-reverse structure is reasonable and has the following advantages:

[0012] (1) The use of vertical rubber pads with locking iron hoops can directly clamp and lock the bolt threads. Due to the use of rubber material, it will deform under the compression of the locking iron hoop, thereby better embedding into the bolt threads and generating greater resistance at the contact point between the split threaded sleeve and the bolt, further preventing the nut from loosening. It can adapt to more extreme working environments and has stronger applicability. The rubber pad adopts a detachable design. After repeated use, the rubber pad can be replaced and continued to be used, reducing production costs. At the same time, it is simple to operate and easy to learn, and is suitable for most usage environments. Through the comprehensive application of material innovation, structural optimization and anti-loosening strategies, the locking nut has significantly improved the stability and safety of industrial equipment. It is particularly outstanding in terms of high precision, corrosion resistance and vibration resistance, and has become a key component for the upgrading of modern industrial automation. When selecting, it is necessary to match the appropriate type according to the specific working conditions (such as vibration intensity, temperature, corrosive environment) to maximize its performance advantages.

[0019] 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.

[0020] Please see Figure 1-5The present invention provides a technical solution as follows:

[0021] Example 1:

[0022] In this embodiment, a hexagonal flange nut with a backstop structure includes a nut 2, two split threaded sleeves 5 are provided on the top of the nut 2, the two split threaded sleeves 5 are fixedly connected to the nut 2, and a flange 1 is fixedly connected to the bottom of the nut 2.

[0023] In this embodiment, two anti-slip pads 4 are provided on the top of the nut 2. The two anti-slip pads 4 are fixedly connected to the nut 2, and the two split threaded sleeves 5 are adapted to the two anti-slip pads 4.

[0024] In this embodiment, an iron hoop 6 is provided on the top of the nut 2, and the iron hoop 6 is adapted to the anti-slip pad 4.

[0025] In this embodiment, a locking bolt 3 is provided on one side of the iron hoop 6, and the locking bolt 3 is compatible with the iron hoop 6.

[0026] In this embodiment, the iron hoop 6 has several threaded grooves.

[0027] In this embodiment, the anti-slip pad 4 is made of rubber.

[0028] Working principle: When using, first use a suitable wrench to turn the nut 2 clockwise. After tightening, use a flathead screwdriver to turn the locking bolt 3 clockwise, causing the iron clamp 6 to gradually tighten and squeeze the internal anti-slip pad 4. The anti-slip pad 4 deforms under the pressure, thus clamping and tightening the bolt inside the anti-slip pad 4. Since the anti-slip pad 4 is made of rubber, it can completely fit the thread, increasing the friction. At the same time, since the nut 2 adopts a split design, the anti-slip pad 4 can also lock the engagement between the external thread of the bolt and the internal thread of the split threaded sleeve 5. When it is necessary to remove the nut 2, first turn the locking bolt 3 counterclockwise, causing the iron clamp 6 to gradually expand and release the pressure on the anti-slip pad 4. Then use a wrench to turn the nut 2 counterclockwise until the nut 2 can be removed.

[0029] 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.
