Description

Technical Field

[0001] This utility model relates to the field of nut technology, specifically a steam nut. Background Technology

[0002] As is well known, steam nuts, as connectors related to steam systems, are mainly used to fix or connect steam pipelines and equipment through threads to ensure safety and stability under high temperature and high pressure.

[0003] The existing lubrication effect of nuts is poor. After long-term use, the lubrication effect of nuts will decrease, which will lead to an increase in the coefficient of friction of nuts and make them prone to wear. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a steam nut.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a steam nut, comprising a body, a pipeline, a plug, and a limiting mechanism. The pipeline is disposed on the inner wall of the body, and there are several pipelines. The plug matches the pipeline, and there are several plugs. The limiting mechanism includes a groove, a spring, and a block. The groove is formed on the body. One end of the spring is connected to the inner wall of the groove, and the other end of the spring is connected to one end of the block. The other end of the block extends out of the groove. There are several limiting mechanisms.

[0008] To facilitate the insertion of the plug into the pipeline, the present invention is improved in that the plug is matched with the pipeline.

[0009] To achieve a sealing effect, the present invention is improved by providing sealing plugs at both ends of the main body, and the sealing plugs are matched with the main body.

[0010] To improve the sealing effect, the present invention is improved by using a rubber material for the sealing plug.

[0011] To facilitate the movement of the block in the groove, the present invention is improved in that the block is matched with the groove.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention provides a steam nut, which has the following advantages:

[0014] This steam nut, with its structure featuring a pipe on the main body, facilitates the addition of lubricating oil to the inner wall of the main body, preventing the lubrication effect from decreasing after prolonged use and thus avoiding increased friction coefficient and wear when the main body is tightened. The limiting mechanism also prevents the plug from separating from the pipe. 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. 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.

[0021] Please see Figure 1-4 A steam nut includes a body 1, a pipe 2, a plug 3, and a limiting mechanism 4. The pipe 2 is disposed on the inner wall of the body 1, and there are several pipes 2. The plug 3 is matched with the pipe 2, and there are several plugs 3. The limiting mechanism 4 includes a groove 5, a spring 6, and a block 7. The groove 5 is formed on the body 1. One end of the spring 6 is connected to the inner wall of the groove 5, and the other end of the spring 6 is connected to one end of the block 7. The other end of the block 7 extends out of the groove 5. There are several limiting mechanisms 4.

[0022] In use, first install the main body 1 in a suitable position. The main body 1 is a conventional steam nut on the market, which is a common technology and will not be described in detail here. By inserting an external syringe into the pipe 2, lubricating oil can be added into the pipe 2. The pipe 2 is connected to the inner wall of the main body 1, so the lubricating oil can flow into the interior of the main body 1 to achieve the lubrication effect. After the lubricating oil is added, press the block 7 to cause the spring 6 in the groove 5 to contract, causing the block 7 to contract. Then insert the plug 3 into the pipe 2, and then release the block 7. The spring 6 will rebound, and then the block 7 will move and abut against the top of the plug 3 to prevent the plug 3 from separating from the pipe 2. The size and shape of all parts in this structure are not specifically limited here and need to be produced according to the actual situation.

[0023] In order to facilitate the insertion of the plug 3 into the pipe 2, in this embodiment, the plug 3 is matched with the pipe 2.

[0024] In this embodiment, sealing plugs 8 are provided at both ends of the main body 1. The sealing plugs 8 are matched with the main body 1. When the main body 1 is not used after leaving the factory, the sealing plugs 8 can seal both ends of the main body 1 to prevent external dust from entering the interior of the main body 1.

[0025] The sealing plug 8 can be made of any material. In order to improve the sealing effect, in this embodiment, the sealing plug 8 is made of rubber.

[0026] In order to facilitate the movement of the block 7 in the groove 5, in this embodiment, the block 7 is matched with the groove 5.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
