Abstract
The invention discloses a binding cylinder, which comprises a cylinder body (1) and a binding connector (12). A main cylinder shaft (9) is disposed in the cylinder body (1), the cylinder body (1) is connected with the binding connector (12) via two tension springs (4), a widened Beto ring is mounted on a piston head of the main cylinder shaft (9), and a steel lining and a sealing ring are additionally mounted on a piston rod of the main cylinder shaft (9). The binding cylinder has the advantages that the binding cylinder is reasonable in structural design, small in friction and fine in sealing performance, and the service life of the binding cylinder is greatly prolonged.
Description
Technical field
The present invention relates to a kind of shoemaking machinery, be specifically related to a kind of oil cylinder of tightening of lasting pincers.
Background technology
Traditional lasting pincers is tightened oil cylinder and is often adopted contained spring control, is not easy to change and maintenance; In addition, piston head on the master cylinder axle and cylinder body often directly produce friction and damage cylinder body, and the piston rod of master cylinder axle is prone to produce skew at the volley, and then damages cylinder body and oil sealing.
Summary of the invention
To existing shortcoming of tightening oil cylinder, the present invention provides a kind of novel oil cylinder of tightening.
To achieve these goals, the measure that the present invention taked:
A kind of oil cylinder of tightening comprises cylinder body and tightens connector, is provided with the master cylinder axle in the cylinder body, cylinder body through two extension springs with tighten connector and be connected, the shellfish filler ring is widened in the piston head installation of master cylinder axle, the piston rod of master cylinder axle installs steel lining and sealing ring additional.
Beneficial effect of the present invention: reasonable in design, it is little to rub, good airproof performance, prolong service life greatly.
Description of drawings
Fig. 1, structural representation of the present invention.
The specific embodiment
A kind of oil cylinder of tightening comprises cylinder body 1 and tightens connector 12, is provided with master cylinder axle 9 in the cylinder body 1; Cylinder body 1 through two extension springs 4 with tighten connector 12 and be connected; Be convenient for changing maintenance, the piston head of master cylinder axle 9 is installed and is widened the shellfish filler ring, prevents that piston head and cylinder body 1 from directly producing the friction damage cylinder body.The piston rod of master cylinder axle 9 installs steel lining and sealing ring additional, prevents to produce skew in the piston rod movement, avoids damaging cylinder body 1 and oil sealing leakage of oil.Beneficial effect of the present invention: reasonable in design, it is little to rub, good airproof performance, prolong service life greatly.
Those skilled in the art's simple change and replacement all are within protection scope of the present invention in this area.
