Description
Technical Field
The utility model belongs to the technical field of the air spring, especially, relate to a buffer type air spring.
Background
The gas spring has wide application, and the working principle of the gas spring is that inert gas or oil-gas mixture is filled in a closed pressure cylinder, so that the pressure in a cavity is many times higher than the atmospheric pressure, and the movement of a piston rod is realized by utilizing the pressure difference generated by the fact that the cross section area of the piston rod is smaller than that of the piston. In the motion process of the piston rod, an oil seal needs to be arranged, the traditional gas spring is poor in buffering performance, only one pressure change can be achieved, and the purpose is limited.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that current air spring buffer performance is relatively poor with the leakproofness, in order to improve its weak point, the utility model provides a buffering type air spring.
In order to achieve the purpose, the utility model is realized by the following technical proposal:
the utility model provides a buffering type air spring, including the cylinder, sliding connection has the piston rod on the cylinder, and the piston rod end that is located the cylinder is connected with the piston, the piston is including two elastic sheet bodies that pile up the setting, the elastic sheet body is including the linkage segment of being connected with the piston rod end, linkage segment outside eaves is connected with flexible section, and the elastic section outside eaves of slope is contradicted on the cylinder inner wall, forms the toper seal groove between two elastic section, the embedded sealing washer that has connect of toper seal groove.
Compared with the prior art, the beneficial effects of the utility model are that: because the elastic sheet body produces the friction with the cylinder inner wall in the piston rod motion process, makes the elastic section of the elastic sheet body take place deformation to extrude the sealing washer in the toper seal groove, improve the leakproofness of device, the degree of deformation is big more simultaneously, and is big more with the contact surface of cylinder inner wall, forms certain cushioning effect to in the piston rod motion process, and the device is applicable to in the industrial production, has very strong practicality.
The free end of the piston rod is provided with a thread section, an adjusting nut is screwed on the thread section, and the adjusting nut abuts against the elastic sheet body connecting section. Adjusting nut can extrude two elastic sheet bodies for the toper seal groove clearance between two elastic segment reduces, thereby makes the inseparabler laminating cylinder inner wall setting of sealing washer, improves the leakproofness of device.
The bottom of the cylinder barrel is provided with a wedge-shaped opening, an end cover is covered on the wedge-shaped opening, and the outer surface of the end cover is a wedge-shaped surface matched with the inner surface of the wedge-shaped opening.
First pin holes are formed in the outer surface of the end cover, second pin holes are formed in the cylinder barrel opposite to the first pin holes, and the first pin holes are in pin joint with the corresponding second pin holes through pin shafts.
The free end of the piston rod, which is positioned outside the cylinder barrel, is connected with an earring, and the bottom of the cylinder barrel is connected with a hinged seat.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partially enlarged view of a portion a in fig. 1.
Fig. 3 is a partially enlarged view of fig. 1 at B.
In the figure: 1 cylinder, 2 piston rods, 3 elastic sheet bodies, 301 linkage segment, 302 elastic segment, 4 toper seal grooves, 5 sealing rings, 6 screw thread sections, 7 adjusting nut, 8 wedge openings, 9 end covers, 10 first pinhole, 11 second pinholes, 12 earrings, 13 articulated seats.
Detailed Description
The technical solution of the present application will be further described and explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1-3, for a buffering type air spring, including cylinder 1, sliding connection has piston rod 2 on the cylinder 1, the 2 ends of piston rod that are located in cylinder 1 are connected with the piston, the piston is including two elastic sheet bodies 3 that pile up the setting, elastic sheet body 3 is including the linkage segment 301 of being connected with 2 ends of piston rod, the outer eaves of linkage segment 301 is connected with elastic segment 302, the outer eaves of elastic segment 302 of slope is contradicted on the 1 inner wall of cylinder, form toper seal groove 4 between two elastic segment 302, the embedded sealing washer 5 that has connect of toper seal groove 4. The free end of the piston rod 2 is provided with a thread section 6, an adjusting nut 7 is screwed on the thread section 6, and the adjusting nut 7 is abutted to the connecting section 301 of the elastic sheet body 3. Adjusting nut 7 can extrude two elastic sheet bodies 3 for the 4 clearances in taper seal groove between two elastic segments 302 shrink, thereby make the setting of 1 inner walls of inseparabler laminating cylinder of sealing washer 5, improve the leakproofness of device. Wedge opening 8 has been seted up to cylinder 1 bottom, and 8 upper covers of wedge opening have closed end cover 9, and the surface of end cover 9 is the wedge face with 8 interior surface fit of wedge opening. The outer surface of the end cover 9 is provided with first pin holes 10, the cylinder barrel 1 opposite to each first pin hole 10 is provided with second pin holes 11, and each first pin hole 10 is in pin joint with the corresponding second pin hole 11 through a pin shaft. The free end of the piston rod 2 positioned outside the cylinder barrel 1 is connected with an earring 12, and the bottom of the cylinder barrel 1 is connected with a hinged seat 13.
During operation, because elastic sheet body 3 produces the friction with 1 inner wall of cylinder at 2 motion in-process of piston rod, make elastic sheet body 3's elasticity section 302 take place deformation to extrude sealing washer 5 in the toper seal groove 4, improve the leakproofness of device, the degree of deformation is big more simultaneously, and is big more with the contact surface of 1 inner wall of cylinder, forms certain cushioning effect to 2 motion in-process of piston rod.
The present invention is not limited to the above embodiments, and based on the technical solutions disclosed in the present invention, those skilled in the art can make some substitutions and modifications to some technical features without creative labor, and these substitutions and modifications are all within the protection scope of the present invention.
