Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a pin end sealing ring. Background Art

[0002] A pin seal is a sealing element used in mechanical connections, usually to prevent liquid or gas from leaking from the connection. It is usually made of elastic materials, such as rubber or plastic, and has a ring-shaped design to adapt to the shape of the connection and provide an effective seal. The seal is usually used at the pin end of the connection to prevent liquid or gas from leaking in the axial direction. It can be found in various industrial and mechanical applications, such as automotive engines, hydraulic systems, pneumatic equipment, etc. The choice of seal depends on factors such as the pressure, temperature and chemical environment of the application. The seal is designed to provide reliable sealing performance and has a certain wear resistance and durability. In order to ensure its normal operation, the seal needs to be checked and replaced regularly to prevent leakage problems caused by aging or wear. In general, the pin seal plays a key role in mechanical connections. It can effectively prevent liquid or gas leakage, thereby ensuring the normal operation of the mechanical system.

[0003] At present, as a part of mechanical connection, pin ends usually involve the transmission of liquid or gas. The main function of the sealing ring is to ensure that the connection does not lose efficiency or function due to axial leakage of liquid or gas. However, once the sealing ring is loose, its sealing performance will be affected, which may cause liquid or gas to leak from the connection; therefore, it does not meet the existing needs. In this regard, we propose a pin end sealing ring. Utility Model Content

[0022] Embodiment 1: This embodiment is intended to facilitate the solution of the problem that the pin end is part of a mechanical connection, which usually involves the transmission of liquid or gas. The main function of the sealing ring is to ensure that the connection does not lose efficiency or function due to axial leakage of liquid or gas. However, once the sealing ring is loose, its sealing performance will be affected, which may cause liquid or gas to leak from the connection. Please refer to Figure 1-4A pin end sealing ring includes a pin end body 110, a pin end disc 111 is connected to the end of the pin end body 110, a sealing ring body 120 is installed on the outer side of the pin end disc 111, a chuck 130 is installed on the side of the pin end disc 111, a groove 140 is provided on the side of the sealing ring body 120, and the chuck 130 is slidably engaged with the groove 140.

[0023] The chuck 130 is configured as a circular ring disk, and the outer side of the chuck 130 is configured as a threaded section. The sealing ring body 120 includes a first sealing ring 121 and a second sealing ring 122. The first sealing ring 121 is arranged above the second sealing ring 122. A sealing body 150 is installed between the first sealing ring 121 and the second sealing ring 122. The sealing body 150 includes a rubber edge 151 and an iron ring 152. The rubber edge is connected to the side of the iron ring 152. The slot 140 is arranged on the side of the iron ring 152. The slot 140 is configured as a threaded slot. The chuck 130 and the slot 140 are threadedly matched for use.

[0024] The design of the annular disk enables the chuck 130 to apply pressure evenly, ensuring that the sealing ring body 120 including the first sealing ring 121 and the second sealing ring 122 are firmly installed on the outside of the pin end disk 111. The cooperation of the threaded section and the threaded groove further enhances the stability of the connection, effectively preventing loosening under vibration or load. The threaded matching design makes the installation and removal of the sealing ring body 120 more convenient and can be completed without complicated tools. This is very important for maintenance and replacement of seals, which can reduce maintenance time and the difficulty of operation for staff. The threaded matching of the chuck 130 and the groove 140 ensures that the sealing body 150 composed of the rubber edge 151 and the iron ring 152 is completely and tightly embedded in the pin end disk 111, effectively preventing the leakage of liquid or gas. The design of the sealing body 150 ensures good elasticity and durability, and maintains the sealing effect for a long time.

[0025] In this embodiment: through the arrangement of the chuck 130 and the slot 140, the sealing body is sleeved on the outside of the pin end disk 111, and the chuck 130 and the slot 140 are threadedly engaged. The chuck 130 and the slot 140 are threadedly engaged, which can ensure that the sealing body is firmly fixed on the outside of the pin end disk 111. This design can effectively prevent the sealing body from loosening or falling off due to vibration or load during use, improve the stability and reliability of the seal, and solve the problem that the pin end is part of the mechanical connection and usually involves the transmission of liquid or gas. The main function of the sealing ring is to ensure that the connection will not lose efficiency or function due to axial leakage of liquid or gas, but once the sealing ring is loose, its sealing performance will be affected, which may cause liquid or gas to leak from the connection.

[0026] Embodiment 2: This embodiment is intended to promote the solution to the problem of loose engagement. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-4The first sealing ring 121 is connected to the first rubber ball 153 on the side, the second sealing ring 122 is connected to the second rubber ball 154 on the side, a cavity 200 is provided inside the sealing ring body 120, the cavity 200 is connected to the first rubber ball 153 and the second rubber ball 154, a notch 155 is provided on the side of the pin end plate 111, and the notch 155 is slidably engaged with the second rubber ball 154;

[0027] The arrangement of the first rubber ball 153 and the second rubber ball 154 forms a cavity 200 inside the sealing ring body 120, and communicates with the first sealing ring 121 and the second sealing ring 122 through the cavity 200. When the notch 155 on the side of the pin end disk 111 is slidably engaged with the second rubber ball 154, the integrity of the sealing system can be effectively maintained to prevent leakage of liquid or gas. The design of sliding engagement enables the sealing ring body 120 to be more conveniently matched with the pin end disk 111 during installation, ensuring the sealing effect and convenience of operation. This is very practical for daily maintenance and replacement of seals, and can reduce maintenance costs and operating difficulties. The elastic design of the first rubber ball 153 and the second rubber ball 154 and the engagement with the notch 155 of the pin end disk 111 ensure the stability of the sealing ring body 120 during operation and the durability of long-term use. This design can maintain sealing performance in various working environments and conditions, improve the reliability of the system, and the sliding engagement ensures a tight connection between the second rubber ball 154 and the pin end plate 111, effectively preventing liquid or gas from leaking from the connection of the sealing system. This is crucial for the safe operation of hydraulic or pneumatic systems in industrial applications. The perfect sealing design not only protects the inside of the mechanical system from the external environment, but also reduces the risk of harmful substances entering the surrounding environment, thereby improving the safety and environmental protection level of the workplace.

[0028] In this embodiment, the first rubber ball 153 and the second rubber ball 154 are arranged, and the first rubber ball 153 and the second rubber ball 154 cooperate with the pin end plate 111. When the sealing ring body 120 is installed, the pin end plate 111 squeezes the first rubber ball 153, and the gas inside the first rubber ball 153 flows to the second rubber ball 154. The second rubber ball 154 is engaged with the notch 155. Under the squeezing of the pin end plate 111, the first rubber ball 153 flows the gas inside the first rubber ball 153 to the second rubber ball 154. After the second rubber ball 154 is engaged with the notch 155, the connection between the pin end plate 111 and the sealing ring body 120 can be effectively sealed to prevent leakage of liquid or gas.
