[0002] An O-ring is a type of sealing ring and is one of the most widely used in hydraulic and pneumatic transmission systems. It is an annular rubber sealing ring with a circular interface and usually plays a role in preventing liquid or gas leakage of mechanical components under static conditions. Therefore, it is widely used in people's daily life and manufacturing processing and other fields. However, some problems still occur during the actual use of existing O-rings.

[0003] For example, the application number 202122167933.8 provides a new type of O-ring, which includes an annular body. A support ring is provided in the middle of the body, a cavity is provided in the middle of the support ring, and several connecting convex bodies are provided on the outer side wall of the support ring and the connecting convex bodies are wrapped in the body. It has the advantages of high support strength and good sealing effect. Most of the existing O-rings do not have an anti-slip function. When installed on mechanical components, the O-ring may slip during the operation of the machine due to the engine oil on the mechanical components, affecting the use of the O-ring. The cross-section of the existing O-ring is often circular and is not easily restored to its original state after being squeezed, resulting in the loss of the sealing effect of the O-ring.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the drawings.

[0030] Combined with Figure 1 , Figure 2 and Figure 4 , a new type of O-ring includes an O-ring body 1. Anti-slip grooves 11 are provided on both the left and right sides of the O-ring body 1. An inner connecting ring 111 is fixedly connected to the inner side of the O-ring body 1. Notches 12 are provided inside the anti-slip grooves 11, and multiple groups of notches 12 are provided. An inner lining strip 13 is also fixedly connected inside the O-ring body 1.

[0031] The present utility model will be further described below in conjunction with embodiments.

[0032] Embodiment 1:

[0033] To solve the problem that most existing O-rings do not have an anti-slip function, and when installed on mechanical components, the O-ring may slip during the operation of the machinery due to the engine oil on the mechanical components, affecting the use of the O-ring. Therefore, the following solution is disclosed. Specifically, please refer to Figures 1-4 , a non-slip inner sleeve 112 is fixedly connected to the inner connecting ring 111, and protrusions are provided on the outer side of the non-slip inner sleeve 112. Anti-slip blocks 121 and friction blocks 122 are also fixedly connected inside the anti-slip groove 11. Multiple groups of anti-slip blocks 121 and friction blocks 122 are provided, and reinforcing bars 123 are fixedly connected to both the left and right sides of the anti-slip block 121. The other end of the reinforcing bar 123 is fixedly connected to the inner side of the anti-slip groove 11. When the O-ring body 1 is installed on a mechanical component, due to the setting of the anti-slip groove 11 on the O-ring body 1, during the installation process of the O-ring body 1, the convex blocks on the mechanical component can be engaged with the inside of the anti-slip groove 11, which can play an auxiliary fixing effect. The setting of the inner connecting ring 111 and the non-slip inner sleeve 112 inside the O-ring body 1 can enable the O-ring to be firmly sleeved on the outer side of the mechanical component, and the notches 12 inside the anti-slip groove 11 can meet the usage requirements of different mechanical components. The setting of the anti-slip blocks 121 and the friction blocks 122 greatly improves the anti-slip performance of the O-ring body 1, avoiding the situation that the O-ring body 1 falls off due to mechanical operation. The setting of the reinforcing bars 123 ensures that the anti-slip blocks 121 will not break away during use, achieving the effect of enabling the O-ring to have a certain anti-slip effect and improving the use effect of the O-ring.

[0034] Embodiment 2:

[0035] To solve the problem that the cross-section of most existing O-rings is often circular, and after being squeezed, it is not easy to return to its original state, resulting in the O-ring losing its sealing effect. Therefore, the following solution is disclosed. Specifically, please refer to Figure 4 and Figure 5, an anti-slip layer 14 is fixedly connected to the outermost side of the O-ring body 1. An anti-cracking layer 141 is fixedly connected to the inner side of the anti-slip layer 14. The anti-cracking layer 141 is composed of polyvinyl chloride. An insulating layer 142 is fixedly connected to the inner side of the anti-cracking layer 141. The insulating layer 142 is composed of silicone rubber. A fastening layer 143 is fixedly connected to the inside of the insulating layer 142. The fastening layer 143 is composed of cross-linked polyethylene. At this time, due to the arrangement of the inner lining strip 13, the O-ring body 1 can still achieve the effect of automatic restoration after being squeezed. The arrangement of the anti-slip layer 14 makes the O-ring body 1 not fall off during use. The arrangement of the anti-cracking layer 141 makes the O-ring body 1 as much as possible protected from tearing when being stretched or the like. The insulating layer 142 enables the O-ring body 1 to have a certain insulating effect and avoid electric shock accidents. The fastening layer 143 can assist the inner lining strip 13 to play a role in the reset effect, realizing the function of being able to be restored after being squeezed, and at the same time making the O-ring body 1 have a certain protection function.
