Abstract
The utility model provides a compound sealing structure for an air cylinder end face. An annular sealing body which is roughly in a Z shape is arranged between an air cylinder body and an end cap. A contact surface between a body and the air cylinder body is provided with a groove. An O-shaped sealing ring is arranged in the groove. A contact surface between the body and the end cap is provided with another groove, and another O-shaped sealing ring is arranged in the another groove. In the compound sealing structure for the air cylinder end face, an air cylinder end face sealing ring is provided with two grooves, and two sealing rings are added, so that a relatively hard end sealing ring not only achieves sealing for two surfaces (the end face and the radial direction) through depending on the relatively hard end sealing ring, but also achieves sealing through the two O-shaped sealing rings. Accordingly, sealing property and reliability of the air cylinder end face sealing ring are strengthened.
Description
Technical field
The utility model relates to a kind of sealing configuration, especially a kind of cylinder end face combined sealing structure.
Background technique
Cylinder is that a kind of compression energy with pressurized gas is converted to mechanical straight-line executive component.Owing to being the compression energy of pressured contracting gas, so to very strict of the requirement of sealing, and as the sealing of end face also very important just, end face seal structure is mainly realized sealing by extruding both at home and abroad, as shown in Figure 1, the cross section roughly is the loop configuration of zigzag, and its material is harder, and elasticity is less.So sealability is not fine, reliability is not strong, easily causes leakage.
The model utility content
The purpose of this utility model provides a kind of cylinder end face combined sealing structure of good sealing effect.
Realize the cylinder end face combined sealing structure of the utility model purpose, the ring packing body that roughly is zigzag between cylinder block and end cap, the surface of contact of described body and cylinder block is provided with groove, is provided with O-ring seals in the groove; The surface of contact of described body and end cap is provided with another groove, is provided with another O-ring seals in described another groove.
Vertical setting of another O-ring seals between O-ring seals between described body and the cylinder block and body and the end cap.
The surface of contact of described body and piston is provided with the buffering protuberance.
The beneficial effect of cylinder end face combined sealing structure of the present utility model is as follows: cylinder end face combined sealing structure of the present utility model, 2 grooves have been opened, 2 seal rings have been added, this is so that harder end seal ring not only relies on itself to realize the sealing of 2 faces (end face with radially), and also realize sealing by 2 O-ring seals, this has just strengthened its sealability and reliability.
Description of drawings
Fig. 1 is the structural representation of existing cylinder end surface seal structure.
Fig. 2 is the structural representation of cylinder end surface seal structure of the present utility model.
Fig. 3 is the local D enlarged view of Fig. 2.
Embodiment
Embodiment of the present utility model is as follows: shown in Fig. 2,3, cylinder end face combined sealing structure of the present utility model, the ring body that roughly is zigzag 1 between cylinder block 4 and end cap 2, described body 1 is provided with groove 5 with the surface of contact of cylinder block 4, is provided with O-ring seals 6 in the groove 5; Described body 1 is provided with another groove 7 with the surface of contact of end cap 2, is provided with another O-ring seals 8 in described another groove 7.
Another O-ring seals 8 vertical settings between O-ring seals 6 between body 1 and the cylinder block 4 and body 1 and the end cap 2.
Surface of contact between body 1 and the piston 3 is provided with buffering protuberance 9.
Cylinder end face combined sealing structure of the present utility model, 2 grooves have been opened, 2 seal rings have been added, this is so that harder end seal ring not only relies on itself to realize the sealing of 2 faces (end face with radially), and also realize sealing by 2 O-ring seals, this has just strengthened its sealability and reliability.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement (as changing the end surface shape of groove and O-ring seals) that the common engineers and technicians in related domain make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
Claims (3)
1. cylinder end face combined sealing structure is characterized in that: the ring packing body that roughly is zigzag between cylinder block and end cap, and the surface of contact of described body and cylinder block is provided with groove, is provided with O-ring seals in the groove; The surface of contact of described body and end cap is provided with another groove, is provided with another O-ring seals in described another groove.
2. cylinder end face combined sealing structure according to claim 1 is characterized in that: the vertical setting of another O-ring seals between the O-ring seals between described body and the cylinder block and body and the end cap.
