Abstract
The utility model relates to a kind of aligning of hydraulic floor spring, for hydraulic floor spring, it discloses aligning install from the lateral vertical of floor spring and can extend to the main hydraulic pressure oil duct of floor spring, and it is corresponding with oil circuit hole in floor spring inner chamber, the front end of aligning is the obstruction head of taper, the stage casing of aligning is provided with thread segment, that section of aligning between thread segment and obstruction head is provided with the axle body section of arc, this axle body section is corresponding with the main hydraulic pressure oil duct of floor spring when aligning is installed to floor spring.The utility model has the advantages that rational in infrastructure, low cost of manufacture, it can form hydraulic oil eddy current buffering at port blocked place while adjustment oil circuit caliber size, make the flow velocity at working connection two ends steady, the accessories such as the piston of floor spring, spring, cam are allowed to be operated in more stable hydraulic oil environment, thus making floor spring long service life, switch gate is more smooth and easy, nature.
Description
Technical field
The utility model relates to a kind of aligning of hydraulic floor spring, with the aligning of hydraulic cushion function while specifically having blocking action to hydraulic floor spring oil circuit.
Background technology
Hydraulic floor spring is in the market common fittings for glass doors, and in hydraulic floor spring mainly piston spill port and working connection carry out oil return speed control in the oil return path of hydraulic oil, market all adopts aligning to the oily uninterrupted of working connection to control oil return speed, but aligning is oil circuit control caliber size, when pressure is large, hydraulic oil becomes spray regime at the port blocked of aligning, so make oily speed in uncontrollable spring pressure process from large to small circulate equably, so control oily fast phenomenon reposefully also reach not other demand, also piston wear is made, the aspects such as spring stress are influenced, thus reduce application life.
Utility model content
The purpose of this utility model is to provide a kind of aligning of hydraulic floor spring, it can form hydraulic oil eddy current buffering at port blocked place while adjustment oil circuit caliber size, make the flow velocity at working connection two ends steady, the accessories such as the piston of floor spring, spring, cam are allowed to be operated in more stable hydraulic oil environment, thus making floor spring long service life, switch gate is more smooth and easy, nature.
Technical solution of the present utility model is on the basis of aligning, be characterized in that aligning is installed from the lateral vertical of floor spring and can extend to the main hydraulic pressure oil duct of floor spring, and it is corresponding with oil circuit hole in floor spring inner chamber, the front end of aligning is the obstruction head of taper, the stage casing of aligning is provided with thread segment, that section of aligning between thread segment and obstruction head is provided with the axle body section of arc, this axle body section is corresponding with the main hydraulic pressure oil duct of floor spring when aligning is installed to floor spring.
Operating principle of the present utility model is the axle body section being provided with arc in that section of aligning between the thread segment and obstruction head of aligning, when acting force of the spring is maximum, when the hydraulic oil of port blocked sprays the strongest, the axle body section place of this section of arc on main oil gallery just produces the highest eddy current of rotating speed thus cushions flow on main oil gallery, along with the minimizing of spring pressure, the minimizing that the hydraulic oil injection of port blocked and the rotating speed of eddy current are also directly proportional thereupon, so ensure that on main oil gallery, flow is close to steady state value, allow the piston of floor spring, spring, the accessories such as cam are operated in more stable hydraulic oil environment, thus make floor spring long service life, switch gate is more smooth and easy, nature.
The utility model has the advantages that rational in infrastructure, low cost of manufacture, it can form hydraulic oil eddy current buffering at port blocked place while adjustment oil circuit caliber size, make the flow velocity at working connection two ends steady, the accessories such as the piston of floor spring, spring, cam are allowed to be operated in more stable hydraulic oil environment, thus making floor spring long service life, switch gate is more smooth and easy, nature.
