Description

Technical Field

[0001] This utility model relates to the field of flange nut technology, specifically a thick flange nut for rail transit. Background Technology

[0002] Existing flange nuts typically consist of two parts: a flange and a nut. When using them, the flange needs to be screwed onto the nut, which is cumbersome and can easily cause the flange to loosen, affecting the performance. A nut is a mechanical part with internal threads that works with a screw to transmit motion or power.

[0003] However, existing flange thick nuts may cause some wear on equipment or pipelines during use, making them inconvenient and inflexible to use. After the nuts and bolts are fixed, they may loosen due to vibration or prolonged use. They may also develop rust and corrosion problems after a short service life. Therefore, we propose a new device to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a thick nut for rail transit flanges, which solves the problems that existing thick nuts may cause wear on equipment or pipelines during use, and that the nuts and bolts may loosen due to vibration or prolonged use after being fixed.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a thick flange nut for rail transit, comprising a mating nut, a mating flange on one side of the mating nut, a fixing bolt threaded through one side of the mating nut, a mating rod inserted into the inner wall of the mating nut, a mating spring on the surface of the mating rod, a mating seat sleeved at one end of the mating rod, a moving rod inserted into the surface of the fixing bolt, a moving spring on the surface of the moving rod, a moving seat inserted into one side of the moving rod, and a limit ring sleeved on the surface of the fixing bolt.

[0008] Optionally, the mating nut has mating threads inside, and the fixing bolt has fixing threads on its surface.

[0009] Optionally, a gasket made of rubber is inserted into one side of the mating flange.

[0010] Optionally, the surface of the mating nut is provided with an anti-slip pad, and the anti-slip pad is made of rubber.

[0011] Optionally, a limiting hole is provided inside the docking nut, and a connecting post is provided on one side of the movable seat.

[0012] Optionally, a sealing ring is fitted onto the surface of the fixing bolt, and the sealing ring is made of rubber.

[0013] Optionally, the surface of the fixing bolt is provided with anti-slip grooves, and the anti-slip grooves are spaced equally.

[0014] Optionally, a contact pad is provided on one side of the docking seat, and the contact pad is made of fluoropolymer-lined material.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model has a reasonable structure. After the user removes the connecting nut, they can hold the anti-slip pad on the surface of the connecting nut and place the connecting nut and connecting flange on the equipment or pipeline, so that the washer on one side of the connecting flange contacts the equipment or pipeline. This achieves convenient and quick use of the connecting nut for fixing, and is simple and flexible to use, thereby reducing wear on the equipment and pipeline caused by the connecting flange. When the user tightens the fixing bolt into the connecting nut, the moving rod is compressed inside the connecting nut, which in turn compresses the moving spring. When the fixing bolt is screwed into the designated position, the moving spring, along with the moving seat on one side of the moving rod, enters the limiting hole, causing the moving seats on both sides of the fixing bolt to move. The fixing bolt is limited by the compression of the connecting rod and the connecting spring. When the fixing bolt is limited, the connecting spring will cause the connecting seat on one side of the connecting rod to pop out. The connecting seat is made easier to move by the conical shape of the contact pad and the limiting ring on one side. The limiting ring on the surface of the fixing bolt limits and fixes the connecting seat. The sealing ring seals the fixing bolt and the connecting nut, which achieves convenient and quick fixing of the fixing bolt. It prevents the fixing bolt from loosening and falling out of the connecting nut due to vibration or long-term use, increases the service life, and reduces the possibility of loosening during a single limiting fixation. It can also prevent the fixing bolt and the connecting nut from rusting and corroding. Attached Figure Description

[0022] 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.

[0023] Example: Reference Figures 1-4 The flange thick nut for rail transit shown includes a mating nut 1, a mating flange 2 on one side of the mating nut 1, a fixing bolt 3 threaded through one side of the mating nut 1, a mating rod 4 inserted into the inner wall of the mating nut 1, a mating spring 5 on the surface of the mating rod 4, a mating seat 6 sleeved on one end of the mating rod 4, a moving rod 7 inserted into the surface of the fixing bolt 3, a moving spring 8 on the surface of the moving rod 7, a moving seat 9 inserted into one side of the moving rod 7, and a limit ring 10 sleeved on the surface of the fixing bolt 3.

[0024] As a preferred embodiment of this example, Figures 2 to 4As shown, a mating flange 2 is provided on one side of the mating nut 1, and a washer 13 is inserted into one side of the mating flange 2. The washer 13 is made of rubber. An anti-slip pad 14 is provided on the surface of the mating nut 1. The anti-slip pad 14 is also made of rubber. A fixing bolt 3 is threaded through one side of the mating nut 1. A fixing thread 12 is provided on the surface of the fixing bolt 3. A mating thread 11 is provided inside the mating nut 1. A mating rod 4 is inserted into the inner wall of the mating nut 1. A mating spring 5 is provided on the surface of the mating rod 4. A mating seat 6 is sleeved on one end of the mating rod 4. A contact pad 16 is provided on one side of the mating seat 6. The contact pad 16 is made of fluoropolymer-lined material. A sliding spring 5 is inserted into the surface of the fixing bolt 3. The moving rod 7 has a moving spring 8 on its surface. A moving seat 9 is inserted into one side of the moving rod 7, and a connecting post is provided on one side of the moving seat 9. The connecting post is connected to the moving rod 7. A limit hole is opened inside the docking nut 1. A limit ring 10 is fitted onto the surface of the fixing bolt 3. A sealing ring 15 is fitted onto the surface of the fixing bolt 3. The sealing ring 15 is made of rubber. The surface of the fixing bolt 3 has anti-slip grooves with equal spacing. During use, after the user removes the docking nut 1, they can hold the anti-slip pad 14 on the surface of the docking nut 1 and place the docking nut 1 and the docking flange 2 on the equipment or pipeline, so that the docking flange 2... One side washer 13 contacts the equipment and pipeline, enabling convenient and quick fixing with the connecting nut 1. This simple and flexible operation reduces wear on the equipment and pipeline caused by the connecting flange 2. When the operator tightens the fixing bolt 3 into the connecting nut 1, the moving rod 7 is compressed within the connecting nut 1, causing the moving spring 8 to be compressed as well. When the fixing bolt 3 is screwed into the designated position, the moving spring 8, along with the moving seat 9 on one side of the moving rod 7, enters the limiting hole, causing the moving seats 9 on both sides of the fixing bolt 3 to limit its movement. The connecting rod 4 and the connecting spring 5 are also compressed. When the fixing bolt 3 is stopped,... The docking spring 5 will cause the docking seat 6 on one side of the docking rod 4 to pop out. The docking seat 6 is more easily moved by the conical shape of the contact pad 16 and the limiting ring 10 on one side. The limiting ring 10 on the surface of the fixing bolt 3 limits and fixes the docking seat 6. The sealing ring 15 seals the fixing bolt 3 and the docking nut 1, which achieves convenient and quick fixation of the fixing bolt 3. It prevents the fixing bolt 3 from loosening and falling out of the docking nut 1 due to vibration or long-term use, increases the service life, and reduces the possibility of loosening during a single limiting fixation, which may cause rust and corrosion on the fixing bolt 3 and the docking nut 1.

[0025] The working principle of this practical application is as follows:

[0026] During use, after the operator removes the docking nut 1, they hold the anti-slip pad 14 on the surface of the docking nut 1 and place the docking nut 1 and the docking flange 2 on the equipment or pipeline, so that the washer 13 on one side of the docking flange 2 contacts the equipment or pipeline. The operator then tightens the fixing bolt 3 inside the docking nut 1. The moving rod 7 is compressed inside the docking nut 1, which in turn compresses the moving spring 8. When the fixing bolt 3 is screwed into the designated position, the moving spring 8, along with the moving seat 9 on one side of the moving rod 7, enters the limiting hole, allowing the moving seats 9 on both sides of the fixing bolt 3 to limit the fixing bolt 3. The docking rod 4 and the docking spring 5 are also compressed. When the fixing bolt 3 is limited, the docking spring 5 will cause the docking seat 6 on one side of the docking rod 4 to pop out. The contact pad 16 and the limiting ring 10 on one side of the docking seat 6 are conical, making it easier for the docking seat 6 to move. The limiting ring 10 on the surface of the fixing bolt 3 limits and fixes the docking seat 6. The sealing ring 15 seals the connection between the fixing bolt 3 and the docking nut 1.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
