Abstract
The utility model discloses an anti-dropping cylinder piston, which comprises a piston body and a piston threaded hole arranged at the center of the piston body. A locking screw hole is arranged on the piston body, and two ends of the locking screw hole are respectively communicated with the edge of the piston body and the piston threaded hole. The anti-dropping cylinder piston is characterized in that the locking screw hole is arranged obliquely, and an included angle between the centre axis of the locking screw hole and a radial centre axis is 12 degrees. The anti-dropping cylinder piston is simple in structure and convenient in manufacturing, and the locking screw hole is arranged obliquely, thereby enlarging contact area between a locking screw and a piston rod, changing the stress direction of the locking screw, increasing stress-bearing strength, and resolving the technical problem that piston bodies are easy to drop in the prior art.
Description
Technical field the utility model belongs to the oil cylinder piston technical field, relates to a kind of Drop-proof oil cylinder piston.
The oil cylinder piston of background technique prior art comprises piston body and is arranged on the piston thread hole at piston body center, piston body radially vertically be provided with the lock screw hole, the two ends in lock screw hole are communicated with the edge and the piston thread hole of piston body respectively.During use, piston body is enclosed within on the piston rod, with lock screw that piston body is fastening.Because the lock screw aperture is to vertical setting, 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 body.
The summary of the invention the purpose of this utility model is to solve prior art to have the caducous technical problem of piston body, a kind of Drop-proof oil cylinder piston is provided, thereby overcomes the deficiencies in the prior art.
For achieving the above object, the utility model Drop-proof oil cylinder piston, comprise piston body and the piston thread hole that is arranged on the piston body center, described piston body is provided with the lock screw hole, and the two ends in lock screw hole are communicated with the edge and the piston thread hole of piston body respectively; Its main points be described lock screw hole deviation to setting, the angle of the center line Off-Radial center line in lock screw hole is 12 °.
The utility model is simple in structure easy to make, because the lock screw hole deviation to setting, has increased the area of contact of lock screw and piston rod, has changed it and has been subjected to force direction, has improved load intensity, has solved prior art and has had the caducous technical problem of piston body.
Appended drawings is the utility model structural representation.
Embodiment with reference to the accompanying drawings, it comprises the utility model piston body 1 and is arranged on the piston thread hole 3 at piston body center, piston body 1 is provided with lock screw hole 2, the two ends in lock screw hole 2 are communicated with the edge and the piston thread hole 3 of piston body 1 respectively; The 2 oblique settings of lock screw hole, the angle of the center line Off-Radial center line in lock screw hole 2 is 12 °.
