Abstract
The invention discloses a scratch-proof press oil seal tool, which belongs to the technical field of tools. The scratch-proof press oil seal tool is in a cylindrical shape, and comprises a handheld end and a press-fitting end, wherein a press-fitting boss is arranged between the handheld end and the press-fitting end; the diameter of the press-fitting boss is larger than the diameters of the handheld end and the press-fitting end; a metal ring sleeve is arranged on the circumferential face of the press-fitting end; the external diameter of the metal ring sleeve is matched with the internal diameter of an oil seal; a circular groove matched with the radial dimension of the oil seal is arranged in the end face, close to the press-fitting end, of the press-fitting boss. The metal ring sleeve is arranged at the locating sleeve connection part of the oil seal, i.e. the press-fitting end, so that the smoothness and the abrasive resistance of the contact face of the tool and the oil seal are improved, the oil seal can smoothly enter the press-fitting end of the tool and can be accurately located without deflecting, the phenomenon that burrs are generated to scratch the oil seal and the like after the tool is used for a long time is avoided, and the service life of the tool is also prolonged.
Description
Technical field
The present invention relates to frock technical field, in particular to a kind of anti-scratch force feed envelope frock.
Background technology
Current manual force feed envelope normally adopts multidiameter, oil sealing utilizes the step of multidiameter to press-fit by being enclosed within multidiameter, in order to prevent the scratch of oil sealing, multidiameter is all adopt the nonmetallic materials such as nylon, roughness is comparatively large, and long-time use after, due to the repeatedly suit of oil sealing in this frock and taking-up, make its surface produce burr, the location at oil sealing and the damage to oil sealing have considerable influence.
Summary of the invention
The object of the present invention is to provide a kind of anti-scratch force feed to seal frock, make oil sealing in frock, be difficult to smooth and easy being in place to solve after existing frock uses for a long time, also can cause the problem of damage to oil sealing.
For realizing the object of the invention, the technical scheme adopted is: a kind of anti-scratch force feed envelope frock, it is cylindric, comprise handheld terminal and press-fit end, handheld terminal and press-fit to be provided with between end and press-fit boss, the diameter press-fiting boss is greater than handheld terminal and press-fits the diameter of end, and the periphery press-fiting end is provided with metal ring, the external diameter of metal ring and the internal diameter of oil sealing match, and what press-fit boss offers near the end face press-fiting end place the annular groove matched with oil sealing radial dimension.
Further, press-fiting boss is that nylon is made.
Further, the outer surface of handheld terminal is provided with anti-skidding lines.
The invention has the beneficial effects as follows, by the location socket place at oil sealing, namely press-fit end and metal ring is set, improve smoothness and the wearability of frock and oil sealing contact surface, oil sealing can enter press-fiting of frock smoothly and hold and accurate positioning, can not deflection, avoid frock and use rear generation burr to cause scratch etc. to oil sealing for a long time, also improve the service life of frock.
Accompanying drawing explanation
Fig. 1 is the sectional view of anti-scratch force feed provided by the invention envelope frock.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1 shows anti-scratch force feed provided by the invention envelope frock, it is cylindric, comprise handheld terminal 1 and press-fit end 2, handheld terminal 1 and press-fit to be provided with between end 2 and press-fit boss 3, the diameter press-fiting boss 3 is greater than handheld terminal 1 and press-fits the diameter of end 2, the periphery press-fiting end 2 is provided with metal ring 4, the external diameter of metal ring 4 and the internal diameter of oil sealing match, what press-fit boss 3 offers near the end face press-fiting end 2 place the annular groove 5 matched with oil sealing radial dimension, is better located oil sealing by frock during for press-fiting.
Wherein, other parts except metal ring 4 press-fit boss 3 grade and can be made up of nylon, are conducive to weight reduction, and prevent that hardness is excessive makes oil seal pressing be out of shape press-fiting in process.The edges at two ends of metal ring 4 is provided with fillet, prevents its edge scratch oil sealing further.Conveniently take use, the outer surface of handheld terminal 1 is provided with anti-skidding lines.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (3)
