Description

Technical Field

[0001] The utility model belongs to the technical field of washer type nuts, in particular to a self-sealing washer type nut. Background Art

[0002] Sealing gasket nuts are usually used in situations where leakproof or sealing is required, such as in high-pressure systems, hydraulic systems or pneumatic systems. This nut design includes a sealing gasket, which is usually made of rubber or other elastic materials and can provide a good sealing effect between the nut and the connection surface. This nut can be used in a variety of different connection systems, including water pipe connections, automotive brake systems, industrial pipelines, etc. Sealing gasket nuts are used in connection systems that require good sealing. Through integrated design, it simplifies the installation process, improves sealing performance, and reduces maintenance costs.

[0003] At the same time, the patent specification with application number 201821192144.1 discloses a gasket nut, including a nut and a gasket that are buckled together and can rotate relative to each other, a threaded hole 1 is provided at the axial center position of the nut, a threaded hole 2 of the same model as the threaded hole 1 is provided at the center position of the gasket, an open groove 1 along the axial direction of the nut and passing through the nut is provided on the nut, and an open groove 2 along the height direction of the gasket and passing through the gasket is provided at a position corresponding to the nut on the gasket, the widths of the open groove 1 and the open groove 2 are equal and slightly larger than the outer diameters of the threaded hole 1 and the threaded hole 2. The gasket nut of this utility model has a reasonable overall structural design, is convenient for quick fixed installation, and improves installation efficiency; after tightening, the gasket nut has the functions of locking and anti-loosening, and the installation is highly firm.

[0004] During the use of an existing gasket nut, the nut sometimes slips off the bolt because the threads on the inner side of the nut are mostly not coated with anti-slip glue. Due to the lack of a shock-absorbing structure, there are many scenarios where nuts are needed. In some scenarios, after the nut is installed, the use of the device causes the bolt to vibrate, thereby causing the nut to vibrate with a small amplitude and high frequency. During the shaking process, the nut sometimes gradually slips off and falls from the outside of the bolt, posing a great safety hazard to the use of the device, reducing the stability of the device, and even threatening the personal safety of the staff.

[0005] Therefore, in order to solve the above problems, a nut with a self-sealing gasket is proposed. Utility Model Content

[0006] In order to solve the problems raised in the above background technology, the utility model provides a self-sealing gasket-type nut, which has the advantages of increasing the anti-slip and anti-shake of the inner thread of the nut and enhancing safety.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a self-sealing gasket type nut, comprising a nut body, a rubber gasket 1 being fixedly connected to the bottom end of the nut body, a stainless steel gasket 1 being fixedly connected to the top end of the nut body, a galvanized layer being bonded to the outer side of the nut body, an anti-slip glue being bonded to the inner side of the nut body, a lower meshing tooth being fixedly provided at the top end of the stainless steel gasket 1, an upper meshing tooth being slidably connected to one side of the lower meshing tooth, a stainless steel gasket 2 being fixedly connected to the top end of the upper meshing tooth, and the upper meshing tooth being in contact with the lower meshing tooth, a rubber gasket 2 being fixedly provided at the top end of the stainless steel gasket 2, and a stainless steel gasket 3 being fixedly connected to the top end of the rubber gasket 2.

[0008] Preferably, the outer side of the stainless steel gasket three is slidably connected with a carbon steel shell, and the aperture of the top end of the carbon steel shell is larger than the aperture of the nut body.

[0009] Preferably, a bolt is slidably connected to the inner side of the nut body, and the bolt is made of stainless steel.

[0010] Preferably, a bolt head is fixedly connected to the top end of the bolt, and the bolt is spirally inserted from one side of the carbon steel shell.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model combines a nut body, a rubber washer 1, a rubber washer 2 and a stainless steel gasket 2 in structure. Before using the sealing gasket nut, the user can set the carbon steel shell sleeve on the outer side of the stainless steel gasket 3. The inner thread surface of the sealing gasket nut is bonded with anti-slip glue. The nut body is rotated clockwise, and the nut body slides in along the outer side of the bolt. After the nut body is rotated to a suitable position, the upper meshing teeth and the lower meshing teeth are meshed with each other to generate an interaction force, so that the nut body can offset the force to the stainless steel gasket when it is hit or vibrated by an external force. A rubber washer 2 is arranged on the top of the stainless steel gasket 2. The rubber washer 2 can offset a part of the vibration force of the device, reduce the relative displacement distance between the nut and the bolt, eliminate the shedding of the nut caused by vibration, thereby improving the stability of the device and avoiding the occurrence of safety accidents.

[0013] 2. The utility model combines a bolt, a rubber washer 1, an anti-slip adhesive and a galvanized layer structure. When using a sealing gasket nut, the user first sets the carbon steel shell sleeve on the outer side of the stainless steel gasket 3, rotates the nut body clockwise along the outer side of the bolt and slides it in. The nut will approach the bolt head. When the nut is rotated to a suitable position, the upper meshing teeth and the lower meshing teeth will mesh with each other. The stainless steel gasket 3 will buffer a part of the impact generated by the vibration of the device. The rubber gasket 2 will offset most of the energy generated by the vibration of the stainless steel gasket 3. The rubber gasket 1 at the bottom end of the nut body can increase the friction between the nut body and the bolt, and reduce the relative displacement between the nut and the bolt caused by the vibration of the device. The surface of the nut body is coated with a galvanized layer. The galvanized layer can prevent the nut body from being corroded by corrosive gases in the air under harsh environments. After the nut is corroded, rust will be generated, which makes it difficult to remove the device when replacing or repairing it, reducing the maintenance efficiency. The galvanized layer can reduce the use cost of the nut while improving the maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4As shown, the utility model provides a self-sealing gasket nut, including a nut body 1, a rubber gasket 2 is fixedly connected to the bottom end of the nut body 1, a stainless steel gasket 3 is fixedly connected to the top end of the nut body 1, a galvanized layer 11 is bonded to the outside of the nut body 1, an anti-slip glue 10 is bonded to the inside of the nut body 1, a lower meshing tooth 4 is fixedly arranged on the top end of the stainless steel gasket 3, one side of the lower meshing tooth 4 is slidably connected to an upper meshing tooth 5, a stainless steel gasket 6 is fixedly connected to the top end of the upper meshing tooth 5, and the upper meshing tooth 5 is fixedly connected to the top end of the stainless steel gasket 6. Tooth 5 fits with lower meshing tooth 4, rubber washer 27 is fixedly provided on the top of stainless steel gasket 26, stainless steel gasket 3 8 is fixedly connected to the top of rubber gasket 27, stainless steel gasket 3 8 buffers the energy generated by the vibration of the device and transfers it to rubber gasket 27, rubber gasket 27 buffers most of the energy generated by the vibration and transfers the remaining energy to stainless steel gasket 26, the upper meshing tooth 5 at the bottom end of the gasket meshes with the lower meshing tooth 4, so that the vibration energy is completely offset, thereby avoiding the nut from slipping due to vibration.

[0021] Specifically, the outer side of the stainless steel gasket 3 8 is slidably connected with a carbon steel shell 9, and the aperture of the top of the carbon steel shell 9 is larger than the aperture of the nut body 1. The carbon steel shell 9 is light in texture and can protect the nut and the internal rubber gasket 2 7 from external forces.

[0022] Furthermore, a bolt 12 is slidably connected to the inner side of the nut body 1, and the bolt 12 is made of stainless steel, which makes the maintenance of the nut more convenient.

[0023] Furthermore, the top end of the bolt 12 is fixedly connected with a bolt head 13, and the bolt 12 is spirally inserted from one side of the carbon steel shell 9. The bolt 12 is rotated and inserted from one side of the carbon steel shell 9, and the carbon steel shell 9 can be fixed together when the nut is tightened.

[0024] Among them, the carbon steel shell 9, the rubber gasket 2, the galvanized layer 11 and the anti-slip glue 10 are prior arts and will not be described in detail. At the same time, the utility model also includes high temperature resistant glue, etc., which are not the main technical points of this patent and will not be described in detail.

[0025] Working principle and process: Before using the sealing gasket nut, the user can put the carbon steel shell 9 on the outside of the stainless steel gasket three 8, and the inner threaded surface of the sealing gasket nut is bonded with anti-slip glue 10. The nut body 1 is rotated clockwise, and the nut body 1 slides along the outside of the bolt 12. After the nut body 1 is rotated to a suitable position, the upper meshing teeth 5 and the lower meshing teeth 4 are meshed with each other to generate an interaction force, so that when the nut body 1 is subjected to external impact or vibration, the force can be offset to the stainless steel gasket one 3. A rubber gasket two 7 is arranged on the top of the stainless steel gasket two 6. The rubber gasket two 7 can offset part of the vibration energy of the device, reduce the relative displacement distance between the nut and the bolt 12, and eliminate the nut falling off due to vibration, thereby improving the stability of the device and avoiding the occurrence of safety accidents. When using the sealing gasket nut When the bolt 12 and the nut are combined, the nut will move toward the head of the bolt 12. In this process, the rubber washer 2 7 at the bottom end of the nut body 1 can absorb most of the energy generated by the vibration of the stainless steel gasket 3 8. At the same time, the presence of the rubber washer 2 increases the friction between the nut and the bolt 12, thereby reducing the relative displacement between the nut and the bolt 12 caused by the vibration of the equipment. In addition, a zinc-plated layer 11 is coated on the surface of the nut body 1. This zinc-plated layer 11 can protect the nut from corrosive gases in the air in harsh environments. If there is no zinc-plated layer 11, the nut may rust, which will make it difficult to remove the nut when replacing or repairing the equipment, thereby reducing the maintenance efficiency. Therefore, this device will improve the stability of the device and reduce the occurrence of nut corrosion.
