Abstract
The utility model discloses a floor spring, comprising a shell body (1) and a susceptor (2). A connecting rod (13), a spring (14), a piston (17), a bearing sleeve (6), a lower movable plate (11), a rotary shaft (7), an upper movable plate (10), a sealing cover (5), a male pin (16), a end cover (20), a governing valve and a sealing screw nail (3) are arranged in the susceptor (2) which is installed in the shell body (1), and a big cover plate (15) and a small cover plate (14) are arranged on the shell body (1). The utility model is characterized in that a butterfly sealing ring (8) and a fixed ring (9) are arranged in the sealing cover (5). A central through hole of the piston (17) is provided with a ball (19) and a quadrat (21), and two grooves are arranged on the circumference of the piston (17) and are inserted in the O-shaped sealing rings (18). Without oil penetration and with stable operation, the utility model easily achieves the standard of GB9296.
Description
The utility model relates to a kind of floor spring.
The store oil parts of regulation floor spring do not allow and ooze, leak phenomenon, its test method for after the store oil parts are inverted 24h among the GB9296-88 " floor spring ", estimate ooze, oil leakage phenomenon.But at present commercially available floor spring often the oil impregnate phenomenon occurs at rotatingshaft and sealing cover place along with access times increases, and galloping when therefore moving often occurs just closed quickly at closing time; Very high to piston and base oil cylinder part requirement on machining accuracy, not so leakage of oil operation in piston edge is just not steady.
The purpose of this utility model is to provide a kind of floor spring, and its sealing is reliable, long service life, easy processing, cost descend.
In order to achieve the above object, the solution that the utility model is taked is: a kind of floor spring, it comprises housing, pedestal, place connecting rod in the pedestal, spring, piston, bearing housing, following mobile plate, rotatingshaft, upper mobile board, sealing cover, between following mobile plate and the upper mobile board with movable post interlock, spring is inserted in connecting rod, piston and connecting rod one end pin pinning, upper mobile board, the following mobile plate and the connecting rod the other end are screwed, end cap cooperates with base oil cylinder end thread to be tightened, at base series flow control valve is installed, sealing cover cooperates with whorl of base to be tightened, be inverted base, tighten sealing screw after the base tank filler sleeve refuels, base is installed in the housing, loads onto large cover and minor flaps; It is characterized in that being provided with in sealing cover butterfly seal ring and retainer ring, the piston central through bore is placed ball and abaculus, has two grooves to imbed two O RunddichtringOs on the piston circumference.
The utility model is compared with existing floor spring, owing to be provided with the butterfly seal ring in sealing cover, sealability is more reliable, and oil pressure makes the butterfly seal ring better to the sealing of rotatingshaft; Because the piston circumference is provided with the O RunddichtringO, the one, good seal performance, the 2nd, the requirement on machining accuracy reduction to piston circumference and oil cylinder has reduced difficulty of processing, has reduced processing cost, reaches the requirement of GB GB9296 easily.Ball in the piston central through bore makes oil turnover steadily, so very steady when door is closed.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing is a front section view of the present utility model.
The utility model comprises housing (1), pedestal (2), place connecting rod (13) in the pedestal (2), spring (14), piston (17), bearing housing (6), following mobile plate (11), rotatingshaft (7), upper mobile board (10), sealing cover (5), between following mobile plate (11) and the upper mobile board (10) with three movable posts (12) interlock, spring (14) is inserted in connecting rod (13), piston (17) and connecting rod (13) one ends pin (16) pinning, upper mobile board (10), following mobile plate (11) is screwed with connecting rod (13) the other end, end cap (20) cooperates with base (2) oil cylinder end thread to be tightened, at base (2) series flow control valve is installed, sealing cover (5) is tightened with base (2) screw-thread fit, be inverted base (2), after refueling, base (2) tank filler sleeve tightens sealing screw (3), base (2) is installed in the housing (1), load onto large cover (15) and minor flaps (4), place butterfly seal ring (8) and retainer ring (9) in the sealing cover (5), be beneficial to effective seal, prevent that rotatingshaft (7) from rotating oil impregnate, piston (17) central through bore is placed ball (19) and abaculus (21), has two grooves to imbed two O RunddichtringOs (18) on piston (17) circumference.
