Abstract
The utility model relates to an oil buffer. The oil buffer comprises a cylinder, wherein a piston rod is perpendicularly and movably arranged in the cylinder; a main oil passage in the perpendicular direction is arranged at the lower end of the piston rod; a marble is contained in the main oil passage; a piston spring is connected below the marble; the upper end of the main oil passage in the piston rod is led to two subordinate oil passages which are led to the middle of the cylinder; the piston spring is arranged below the main oil passage. With the adoption of the technical scheme, the two subordinate oil passages are added, so that the buffer effect is improved; then an oil cup cap is added on the piston rod, so that the stability of the piston rod during movement is improved.
Description
Technical field
The utility model belongs to the assembly of handcart, is specifically related to a kind of oil dashpot.
Background technique
It is simple in structure for oil dashpot in handcart of the prior art, and its cushioning effect is poor, and stability is low.
Summary of the invention
The utility model, in order to solve the technical problem of mentioning in background technique, provides a kind of oil dashpot.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of oil dashpot, comprise cylinder body, in cylinder body, vertical motion is provided with a piston rod, the lower end of piston rod is provided with the main oil gallery of Vertical direction, hoodle is housed in main oil gallery, two sub-oil ducts are led in main oil gallery upper end in piston rod, and seed oil road leads to the neutral position of cylinder body, and underpart of the piston rod arranges piston spring.
Piston rod is movably arranged in an oil cup cap, and oil cup cap is fixedly mounted in cylinder body, is provided with some circle seal rings between piston rod and oil cup cap.
The upper end of piston rod is installed and is connected with a piston cap by a horizontally disposed resilient key.
Adopt after above technological scheme: the utility model has increased by two sub-oil ducts, improve the effect of buffering, then on piston rod, increased oil cup cap, the stability of the movement process of piston rod is provided.
