Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing gaskets, in particular to a composite sealing gasket. Background Art
[0002] A sealing gasket is a sealing material used to prevent liquid or gas leakage. It is usually placed between two connecting parts to ensure that there will be no leakage at the connection. Sealing gaskets can fill uneven surfaces, reduce vibrations and prevent corrosion, thereby maintaining a close connection between connecting parts. Sealing gaskets are usually made of metal, rubber, plastic and other materials, and are widely used in pipelines, mechanical equipment, automobiles and other fields. Existing sealing gaskets are mostly made of a single layer of rubber. When in use, the soft rubber will deform after being squeezed and fit tightly with the connecting parts to achieve sealing. However, since the sealing gasket is thin and has a limited stretch range, a large extrusion force is required to ensure sealing. Moreover, shrinkage due to environmental influences will affect the sealing effect. In addition, it is difficult for the rubber to recover quickly after being squeezed and deformed for a long time, which affects its reuse. Utility Model Content
[0003] In order to solve the above problems, the utility model provides a composite sealing gasket with large extension range, small required extrusion force, good sealing performance, automatic and rapid recovery and convenient recycling.
[0004] In order to solve the above-mentioned technical problems, the technical solution proposed by the utility model is: a composite sealing gasket, including a gasket body, a reinforcement pad, a spring and an airbag, the gasket body is provided with an annular cavity, the reinforcement pad is symmetrically fixed in the annular cavity and arranged close to the two side walls of the annular cavity, a plurality of the springs are fixed between two reinforcement pads, the two ends of the spring are respectively connected to the two reinforcement pads, and a plurality of the airbags are fixed between the reinforcement pads and the side walls of the annular cavity.
[0005] Furthermore, the gasket body and the reinforcement spacer are made of rubber.
[0006] Furthermore, the springs are arranged in a plurality of groups in an annular shape in the annular cavity, and the springs in adjacent annular layers are arranged in a staggered manner.
[0007] Furthermore, gaskets are connected at both ends of the spring, the gaskets are fixedly connected to one side of the reinforcement spacer, and the edges of the gaskets are arc surfaces.
[0008] Furthermore, the gasket is made of metal.
[0009] Furthermore, the airbag is hemispherical, and the side of the airbag close to the reinforced spacer is spherical.
[0010] Compared with the prior art, the utility model has the following advantages: an annular cavity is provided in the gasket body, and the spring and the airbag are arranged in the cavity, so that the gasket can have a larger longitudinal extension range when subjected to force, so that the sealing gasket can still be tightly attached to the connecting component when subjected to a smaller extrusion force, and the multiple springs and airbags can make the sealing gasket deform to adapt to the shape of the connecting component to achieve good sealing, the recovery speed of the spring and the airbag is faster than that of the rubber pad and the service life is long, and the gasket body can be automatically pushed to recover quickly after disassembly, which is convenient for disassembly and recycling. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a front cross-sectional view of the utility model.
[0013] As shown in the figure: 1. Gasket body; 2. Reinforcement spacer; 3. Spring; 4. Airbag; 5. Gasket. DETAILED DESCRIPTION
[0014] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0015] Combined with Figure 1 A composite sealing gasket includes a gasket body 1, a reinforced spacer 2, a spring 3 and an airbag 4. The gasket body 1 is provided with an annular cavity. The reinforced spacer 2 is symmetrically fixed in the annular cavity and arranged close to the two side walls of the annular cavity. The gasket body 1 and the reinforced spacer 2 are made of rubber material, which is convenient for the fitting parts to deform and has good sealing performance.
[0016] Combined with Figure 1 , Attachment Figure 2 The plurality of springs 3 are fixedly arranged between the two reinforcing spacers 2. The springs 3 are arranged in a plurality of groups in an annular shape in the annular cavity. The springs 3 in adjacent annular layers are staggered to ensure that the side wall of the gasket body 1 is fully stressed, thereby ensuring its sealing performance.
[0017] Combined with Figure 1 The two ends of the spring 3 are respectively connected to two reinforcement spacers 2, and the two ends of the spring 3 are connected with gaskets 5, which are fixedly connected to one side of the reinforcement spacer 2. The edge of the gasket 5 is an arc surface, which can effectively prevent the edge of the gasket 5 from scratching the reinforcement spacer 2, and is safe and stable. The gasket 5 is made of metal and has a good supporting effect, thereby ensuring the effective expansion and contraction of the spring 3.
[0018] Combined with Figure 1The plurality of airbags 4 are fixedly arranged between the reinforcement spacer 2 and the side wall of the annular cavity. The airbag 4 is hemispherical, and the side of the airbag 4 close to the reinforcement spacer 2 is spherical, which can increase the contact area between the airbag 4 and the side wall of the annular cavity, so that the force of the gasket body 1 on the components is uniform and effective, and can also provide sufficient space for the deformation of the airbag 4, so that it is convenient for it to exert force on the gasket body 1.
[0019] The specific implementation mode of the utility model is as follows: the gasket body 1 is placed between two components that need to be connected, and one of the components is passed through the annular hole in the middle of the gasket body 1. The components are close to each other and will squeeze the gasket body 1, and the airbag 4 and the spring 3 will be deformed and compressed due to the squeezing. At the same time, the elastic force of the spring 3 and the tightening force of the airbag 4 will make the side wall of the gasket body 1 press the two components tightly, and the spring 3 and the airbag 4 at different positions will produce different degrees of deformation due to the shape of the components, thereby ensuring that the gasket body 1 is in close contact with the components in all directions to achieve a good sealing effect. When the sealing gasket is removed, the spring 3 and the airbag 4 will automatically and quickly recover, thereby driving the outer wall of the gasket body 1 to be reset, which is convenient for reuse.
[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
