Description

Spring buffer cushion shock absorber
Technical Field
The utility model relates to a shock attenuation equipment, concretely relates to spring buffer bumper shock absorber.
Background
Need use the bumper shock absorber on the car, the shock attenuation range of reduction car that the bumper shock absorber can be fine, the bumper shock absorber adopts built-in spring bumper shock absorber simultaneously, because of its compact structure, characteristics such as shock attenuation effect are liked by the customer deeply, built-in spring bumper shock absorber among the prior art, built-in spring upper end card is on the working cylinder, the lower extreme is unsettled, when bumper shock absorber limit operating mode is moved, the piston rod is easy tensile to the longest state more, stopper and built-in spring direct rigid contact, the life-span of bumper shock absorber has been influenced to a certain extent, the travelling comfort that the customer was taken a bus has been reduced, exist among the prior art: when the shock absorber is used, the built-in spring is easy to wear, and when the shock absorber is used, the phenomenon that the built-in spring is broken easily occurs, so that the shock absorption effect of the shock absorber is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a built-in spring easily wears out when solving the bumper shock absorber that exists among the prior art and using, the phenomenon of built-in spring rupture easily appears when using the bumper shock absorber, has influenced the technical problem of the shock attenuation effect of bumper shock absorber, and the phenomenon that the reduction built-in spring that can be better easily worn and torn in the use is proposed at present, lets the better spring cushion bumper shock absorber of bumper shock absorber shock attenuation effect.
The technical scheme of the utility model is that: the spring buffer cushion shock absorber is provided with a piston rod, a gland and a tray, a piston valve is arranged at the tail of the piston rod, an internal spring is arranged at the middle position of the piston rod, two ends of the internal spring are tightly attached to form a buffer cushion, a limiting ring is arranged on one side of the piston rod, the thickness of the limiting ring is larger than the back degree of the piston rod, and the inner wall of the limiting ring is tightly attached to the outer wall of the internal spring.
The buffer pad is of a circular ring-shaped structure and is attached to the built-in spring for arrangement.
The outer surface of the piston rod is sleeved with a gland.
The rear side laminating of gland be provided with the tray, just the tray be the outside of oblique form setting at the piston rod.
Extrusion gaps are arranged among the built-in springs, and the extrusion gaps are arranged at equal intervals.
The piston rod and the piston valve are sleeved with an oil storage cylinder, and the piston rod moves back and forth in the oil storage cylinder.
The utility model has the advantages that: when using the bumper shock absorber, nylon blotter is respectively installed at built-in spring both ends, blotter and built-in spring tight fit, fix the spring simultaneously, make spring and piston rod and working cylinder radially keep apart, simultaneously again can the axis on the piston rod slip, simultaneously can not produce the noise again, when the piston rod is tensile to the certain condition, the stopper is earlier with the cushion flexonics, the spring pressure and, produce reaction force to the spacing ring, produce cushioning effect, make to strike softer, show the operating mode that has improved the director, the life of extension bumper shock absorber, the travelling comfort that the customer was taken a bus obviously improves.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a cross-sectional view of the present invention.
Fig. 3 is a schematic view of the overall assembly of the present invention.
In the figure: the device comprises a piston rod 1, a gland 2, a tray 3, a piston valve 4, a built-in spring 5, a cushion pad 6, a limiting ring 7 and an oil storage cylinder 8.
Detailed Description
As shown in fig. 1, the spring buffer shock absorber is provided with a piston rod 1, a gland 2 and a tray 3, a piston valve 4 is arranged at the tail of the piston rod 1, an internal spring 5 is arranged along the middle position of the piston rod 1, two ends of the internal spring 5 are tightly attached to a buffer pad 6, a limit ring 7 is arranged at one side of the piston rod 1, the thickness of the limit ring 7 is greater than the rear degree of the piston rod 1, and the inner wall of the limit ring 7 is tightly attached to the outer wall of the internal spring 5.
As shown in fig. 2, the cushion pad 6 has a circular ring structure, and the cushion pad 6 is attached to the inner spring 5, so that the cushion pad 6 can reduce the impact force of the pressing spring on the retainer ring 7, and the outer portion of the inner spring 5 is not easily worn.
As shown in fig. 3, the outer surface of the piston rod 1 is sleeved with the gland 2, the rear side of the gland 2 is provided with the tray 3 in a fitting manner, the tray 3 is obliquely arranged outside the piston rod 1, and the gland 2 and the tray 3 are matched with each other, so that the shock absorber can be used more safely.
Be provided with extrusion gap between built-in spring 5, extrusion gap between equidistant setting, extrusion gap can let built-in spring's the more even of the extruded force, can be fit for the extrusion resilience of different operating modes.
The outside cover of piston rod 1 and piston valve 4 is equipped with oil storage jar 8, just piston rod 1 round trip movement in oil storage jar 8, the oil storage jar can let the use of bumper shock absorber more comfortable, relies on the drive of oil pressure to the piston rod for the motion of piston rod 1 can be more steady and comfortable.
