Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to a self-locking insulating gasket. Background Art

[0002] Gaskets are mechanical seals between two objects, usually used to prevent pressure, corrosion and natural thermal expansion and contraction of pipelines. Since the machined surface cannot be perfect, gaskets can be used to fill irregularities. Gaskets are usually made of sheet materials such as pad paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, glass fiber or plastic polymers (such as polytetrafluoroethylene). Gaskets for specific applications may contain asbestos.

[0003] When some devices that need to be insulated are assembled with some conductive material parts, insulating rubber pads are needed for insulation isolation. Conventional insulating pads have a simple structure and no self-locking function.

[0004] In some complex scenarios, such as in an environment with large vibration or impact, the gasket may loosen or fall off, causing insulation failure, which in turn may lead to safety hazards such as short circuit and leakage. In some assembly scenarios with limited space or complex structure, some existing insulation gaskets do not have flexible adaptability and convenient installation methods. Installers may need to use additional fixings, adhesives or complex operating steps to ensure the stability of the gasket, which not only reduces work efficiency, but also may affect the overall assembly quality.

[0005] In view of this, we propose a self-locking insulating gasket. Utility Model Content

[0006] The purpose of the utility model is to provide a self-locking insulating gasket to solve the problem in the above background that conventional insulating gaskets have a simple structure, no self-locking function, and are inconvenient to install in some complex scenes.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A self-locking insulating gasket comprises a conductor and a device, wherein a first gasket is arranged on the right side of the conductor, a self-locking part is fixedly installed on the outer surface of the first gasket, a second gasket is arranged between the conductor and the device, a nut is arranged on the left side of the device, the internal meshing of the nut is equipped with a screw, and the screw is connected with the internal meshing of the second gasket; the self-locking part comprises an elastic clip installed on the outer surface of the first gasket, and the elastic clip is symmetrically installed on the outer surface of the first gasket.

[0009] As a further solution of the present invention: the first gasket and the second gasket are set to insulating materials, and the first gasket is inserted into the inside of the second gasket.

[0010] As a further solution of the utility model: two groups of fixing blocks are installed on the outer surface of the first gasket, and through holes are opened on the outer surface of the conductor, and the shapes of the through holes are adapted to the shapes of the fixing blocks and the self-locking parts.

[0011] As a further solution of the utility model: a hexagonal groove is formed on the outer surface of the first gasket, and the screw is configured as a hexagonal screw adapted to the hexagonal groove.

[0012] As a further solution of the utility model: the screw passes through the first gasket, the conductor, and the second gasket, and the interior of the device extends to the interior of the nut.

[0013] Beneficial effects of the utility model:

[0014] (1) The utility model provides a first gasket with a self-locking member, so that when the screw passes through the first gasket and is tightened, the outer surface of the screw will squeeze the self-locking member, causing the self-locking member to produce a certain deformation and store elastic potential energy. As the screw continues to be tightened, the rebound force of the self-locking member gradually increases, generating a reverse force on the outer surface of the screw, thereby having a certain fixing effect on the screw, effectively preventing the gasket from loosening under vibration or impact, and improving the stability and reliability of the insulation effect;

[0015] (2) The utility model provides a self-locking part to perform elastic locking during the installation process, so that the gasket can be stably installed without the need for additional fixings or adhesives, thereby reducing the assembly difficulty and time cost and facilitating quick installation.

[0023] 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 of 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.

[0024] Example: See Figure 1 - Figure 5 As shown, the utility model is a self-locking insulating gasket, comprising a conductor 1 and a device 2, wherein a first gasket 3 is arranged on the right side of the conductor 1;

[0025] The first gasket 3 is provided to provide a buffer layer between the conductor 1 and the screw 6, thereby increasing stability;

[0026] A hexagonal groove is formed on the outer surface of the first gasket 3, and the screw 6 is configured as a hexagonal screw 6 adapted to the hexagonal groove;

[0027] The hexagonal groove and the hexagonal screw 6 can be tightly combined, effectively preventing the screw 6 from sliding or loosening during rotation, improving the stability of assembly, and setting the screw 6 as a hexagonal screw is easy to obtain and install, reducing maintenance costs.

[0028] The screw 6 passes through the first gasket 3, the conductor 1, the second gasket 4, and the inside of the device 2 extends to the inside of the nut 5;

[0029] The first gasket 3, the conductor 1, the second gasket 4, and the device 2 are tightly connected together by screws 6 to form a compact and stable overall structure;

[0030] A self-locking member 301 is fixedly mounted on the outer surface of the first gasket 3. The self-locking member 301 includes an elastic clamp mounted on the outer surface of the first gasket 3, and the elastic clamp is symmetrically mounted on the outer surface of the first gasket 3.

[0031] The elastic clamp utilizes the elastic deformation ability of the material itself to generate deformation and store energy during the process of screwing the screw 6. When the screw 6 stops being screwed, the elastic clamp will try to return to its original shape and generate a rebound force in the process. This rebound force is used to generate additional tightening force on the screw 6, so that the screw 6 can be more stably stuck in the first gasket 3 and the second gasket 4 with the self-locking member 301.

[0032] And the self-locking member 301 is installed symmetrically, so that the elastic clamp can be evenly distributed when applying the fastening force, thereby increasing stability;

[0033] At the same time, the self-locking member 301 is set as an elastic clamp, so that the self-locking member 301 can still maintain stable performance after multiple uses;

[0034] A second gasket 4 is provided between the conductor 1 and the device 2, a nut 5 is provided on the left side of the device 2, and a screw 6 is provided for the internal engagement of the nut 5;

[0035] The device 2 is fixed to the conductor 1 by the cooperation of the screw 6 and the nut 5;

[0036] The screw 6 is meshed and connected with the inside of the second gasket 4, so that the screw 6, the second gasket 4 and the conductor 1 can be fixed together separately, which is convenient for the installation of the subsequent device 2 and reduces the installation problems caused by small space or complex scenes;

[0037] Two sets of fixing blocks are installed on the outer surface of the first gasket 3, and through holes are opened on the outer surface of the conductor 1, and the shape of the through holes is adapted to the shape of the fixing blocks and the self-locking member 301;

[0038] The shape of the through hole is set to match the shape of the fixing block and the self-locking member 301, so that the fixing block can be accurately inserted into the through hole of the conductor 1 to form a stable support structure, which can play a positioning role during the insertion process and reduce the possibility of misalignment and deviation;

[0039] It should be noted that, since the through hole is provided to prevent the first gasket 3 from rotating, the nut 5 can be directly tightened from one side to achieve a locking effect during installation and fixing;

[0040] The first gasket 3 and the second gasket 4 are made of insulating material, and the first gasket 3 is inserted inside the second gasket 4;

[0041] The choice of insulation material ensures electrical safety, prevents current from flowing in unwanted paths, and insulation materials generally have good chemical and heat resistance to maintain stable performance;

[0042] Working principle of the utility model: when the screw 6 passes through the first gasket 3, the conductor 1 and the second gasket 4 and is tightened, the outer surface of the screw 6 will squeeze the contact point of the self-locking member 301, so that the self-locking member 301 will produce a certain deformation and store elastic potential energy. As the screw 6 continues to be tightened, the resilience of the self-locking member 301 gradually increases, and finally a reverse force, i.e., a tightening force, is generated on the outer surface of the screw 6. This tightening force helps to firmly fix the first gasket 3 between the screw 6 and the conductor 1, and prevents the first gasket 3 from loosening under vibration or impact;

[0043] Through the above operation, the screw 6, the first gasket 3, the conductor 1 and the second gasket 4 can be installed into a whole, and then the device 2 to be installed is installed on the screw 6, and then the matching nut 5 is installed on the outer surface of the screw 6 and then tightened.

[0044] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
