Abstract
The utility model discloses a hydraulic oil cylinder piston rod which comprises a piston rod and a double treaded screw; wherein a counter sink of a certain depth is bored at the centre of the end surface of the piston rod wherein the piston rod is connected with the piston, an internal thread is made in the counter sink and one end of the double threaded screw is screwed into the counter sink to be fixed while the other end is connected with the piston. The shearing strength of the double threaded screw is high to make the double threaded screw less prone to breakage caused by axial force and the broken double threaded screw can be conveniently taken out for replacement to allow the piston to continue to serve.
Description
Technical field
The utility model relates to a kind of hydraulic cylinder piston rod
Background technique
The piston rod of hydraulic jack adopts usually with piston and is threaded, normally be processed into one owing to be used to connect the threaded connector of piston on the piston rod with piston rod, when frequently being subjected to radial force at work, piston rod does the time spent, threaded connector is easy to rupture at the tool withdrawal groove place, cause the hydraulic jack cisco unity malfunction, piston rod has only to be done to scrap processing, both caused waste, and piston rod is changed very inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of hydraulic cylinder piston rod, to overcome the problem that piston rod ruptures easily because of the bearing radial force threaded connector; The head rupture piston rod is recycling in case be threaded, and maintenance is changed conveniently.
A kind of hydraulic cylinder piston rod comprises piston rod, double threaded screw, bores the counter sink of appropriate depth in the end face central position that piston rod is connected with piston, machining internal thread in counter sink, and one of double threaded screw screws in counter sink and fixing, and the other end connects piston.
Because the shear strength height of double threaded screw, be not subject to the radial force effect and rupture; In case and double threaded screw ruptures, can be easily with its double threaded screw that takes out and more renew, piston rod still can continue to use.
Description of drawings
Figure is the utility model and piston assembling schematic representation.
Among the figure: 1. piston rod, 2. double threaded screw, 3. piston.
Embodiment
As shown in the figure, bore the counter sink of appropriate depth in end face central position that piston rod 1 is connected with piston 3, machining internal thread in counter sink, one of double threaded screw 2 screws in counter sink and fixing, and the other end is used for and being connected of piston 3.Adding the center of noting internal thread man-hour should be consistent with the center of counter sink.
