In some embodiments, it is high to be less than the tooth that remaining turns tooth for the tooth height of inclined teeth.As a result, inclined teeth plays very
Good guiding role.
In some embodiments, the side of oilhole is equipped with the second mounting hole, the outer end face of the second mounting hole and ontology
Outer end face flush, the aperture of the second mounting hole are more than the aperture of oilhole.It is equipped with the second mounting hole as a result, can facilitate the
Current-limiting apparatus is installed on two mounting holes, so as to control the flowing velocity of ontology both sides hydraulic oil, meets different closing velocities
Requirement.
In some embodiments, adjacent the distance between the tooth that turns is 3.93mm, and the tooth wall for turning tooth is obliquely installed, inclination angle
Degree is 20 °.Thus, it is possible to be rotated convenient for mutually matched tooth, effectively prevents tooth and stuck phenomenon occur in rotation, protect
Fluency when using is demonstrate,proved.
In some embodiments, it is equipped with protrusion on the outside of ontology both ends, the outer diameter of both sides protrusion is equal, protrusion and ontology
It is an integral molding structure.It is equipped with protrusion as a result, the flowing of outer body hydraulic oil can be prevented, is convenient for ontology and other component
Tight fit.
In some embodiments, wherein the end face of side protrusion is equipped with installation screens, installs the outer diameter of screens less than convex
The outer diameter risen, installation screens are located at the opposite sides of the first mounting hole with the second mounting hole.It is equipped with installation screens as a result,
The buckle with the spring of body fits can be facilitated.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model door closer piston；
Fig. 2 is the schematic cross-sectional view of the utility model door closer piston.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to figs. 1 to Fig. 2：Door closer piston, including ontology 1, ontology 1 are equipped with the first mounting hole 11, the first mounting hole 11
Run through ontology 1 along the radial direction of ontology 1, the two lateral walls of the first mounting hole 11, which are equipped with, turns tooth 2, and the number of teeth for turning tooth 2 is
Five, first tooth for turning tooth per side is inclined teeth 21, and the end slope of inclined teeth 21 is arranged, the end face angle of two inclined teeths 21
It is 36 °, is equipped with oilhole 3 along the axial direction of ontology 1, oilhole 3 runs through ontology 1.
In actual use, the tooth 2 that turns of the first mounting hole 11 is matched with the tooth in shaft, and shaft connects with pivoted arm
It connects, pivoted arm is connect with door leaf；It is rotated by the connect band turn arm and shaft of door leaf, shaft coordinates with tooth 2 is turned, to realize
Ontology 1 is driven to move.When the spindle is rotated, corresponding guiding role of the tooth Jing Guo inclined teeth 21 in shaft, is nibbled with tooth 2 is turned
It closes, shaft is effectively prevent stuck phenomenon occur in rotation.
Turning tooth 2 by the second tooth, the distance for turning 2 tooth top of tooth being oppositely arranged is 12.9mm, and the distance of bottom of the tooth is 18mm.
