Abstract
The utility model discloses a device capable of preventing an oil cylinder piston from getting loose, which comprises a piston and a piston rod, wherein the head end of the piston rod is sheathed with the piston; a sealing piece is arranged on the piston; and the device adopts the key points that a two-step diameter reduction structure is adopted by the head end of the piston rod from the inside to outside, and a right-handed nut and a left-handed nut are respectively arranged on the two-step diameter reduction structure. The device with simple structure is convenient to manufacture; in addition, the head end of the piston rod adopts the two-step diameter reduction structure, and the right-handed nut and the left-handed nut are respectively arranged on the two-step diameter reduction structure so as to firmly fasten the piston to the piston rod, so that the technical problem in the prior art that the piston is easy to fall out can be solved.
Description
Technical field the utility model belongs to the oil cylinder piston technical field, relates to a kind of anti-oil cylinder piston release.
The oil cylinder piston of background technique prior art comprises piston and piston rod, and piston sleeve is contained in the head end of piston rod.During use, piston sleeve is on piston rod, fastening with piston with lock screw, and in the time of fixedly, lock screw and piston rod are to contact, and area of contact is little, a bearing radial force, and load intensity is low, has the caducous technical problem of piston.
The summary of the invention the purpose of this utility model is to solve prior art to have the caducous technical problem of piston, a kind of anti-oil cylinder piston release is provided, thereby overcomes the deficiencies in the prior art.
For achieving the above object, the utility model is prevented oil cylinder piston release, comprises piston and piston rod, and piston sleeve is contained in the head end of piston rod, and piston is provided with Sealing; Its main points are that the head end of described piston rod is two rank undergauge structures from inside to outside successively, are respectively equipped with right-handed nut and left-handed nut on the two rank undergauge structures.
The utility model is simple in structure easy to make, because the head end of piston rod is two rank undergauge structures, be respectively equipped with right-handed nut and left-handed nut on the two rank undergauge structures, two nuts are subjected to pretightening force sturdy, be mutual locking trend, piston firmly is fastened on piston rod, has solved prior art and had the caducous technical problem of piston.
Appended drawings is the utility model structural representation.
Embodiment with reference to the accompanying drawings, it comprises piston 4 and piston rod 5 the utility model, piston 4 is sleeved on the head end of piston rod 5, piston 4 is provided with Sealing 3; The head end of piston rod 5 is two rank undergauge structures from inside to outside successively, is respectively equipped with right-handed nut 2 and left-handed nut 1 on the two rank undergauge structures.
