Abstract

Door closing device for two-way sliding doors Type of embedded in the upper frame with performance characteristics By using the camshaft as the act of closing the door And there are pistons to create resistance in the open-close stroke of the door by the resistance arising from the hydraulic fluid. Contained in the engine block When the piston moves There is a filter, hydraulic oil to filter impurities from flowing into the system. And can be adjusted to slow or fast closing the door by adjusting the oil valve The barrier between the piston chamber and the cylinder block. As for the opening of the door, it is a working relationship between the camshaft and the rollers. When the door leaf is opened more than 90 degrees or open beyond normal.

Claims (1)

1.Door closing device for two-way sliding door Type embedded in the upper frame of the gate and is a 1-valve type consisting of a boxed cylinder block (1). To install a camshaft (17) with a shaft protruding above it for attaching to the door. To be used to force the door shut-open, the mechanism of the door closing device for the two-way sliding door consists of - Inside the box of the cylinder tiger (1) is installed a piston (6) and a spring (3) with a piston rod (2) with the other end. It is attached to the cam mounting bottom plate (16) and the top plate fixing the cam (19) with the cam plate fixing pin (20), the piston part (6) is fixed to the piston rod (2) with the piston rod fixing pin (4) - piston. (6) cylindrical It will have children (8) that will act to force it to flow in one way. And has a piston pin to prevent the ball climb (7) block the ball bearing (8) another class - the piston closes the chamber (10) with a thread. For screwing off the cylinder (1) with a ring (9) to prevent oil leakage in the second layer. Before screwing it off - Ball shaft (17 ) That has a spindle appearance And there is a control disc that looks like a Bodhi leaf with a grooved shoulder on both sides To support the roller pins (18) are attached to the camshaft bottom plate (16) and the top plate of the cam (19), sandwiched together by the camshaft pin (20) - the camshaft (17), with the bottom shaft inserted. In the cylinder block (1) that is made into a hole with a ball bearing (15) as a support for rotation. The top shaft will be assembled with Bearing (21) with a second hydraulic oil seal ring (23) prevents oil from leaking out after assembly. The ends of the camshafts (17) are protruding square bars. It is intended to be attached to a two-way sliding door. - The engine block cap (25) is round \ 'and is threaded, the center part is drilled to fit the camshaft (17) and has a socket in the bottom center for fitting with the camshaft. (21) There is a gasket (24) as a secondary protection against oil leaks. When assembled with a cylinder block (1) - the valve (14) is a round bar with a concave groove. It has a thread for attaching the cylinder block (1) at the end to be reduced to a smaller size, with a ring (11), a valve washer (12) and a valve insert (13) to prevent leaking of high-grade oil. Licks in the piston chamber on another floor. - There is a special feature: there will be the inner center of the piston (6), a hole is drilled through the shoulder to install the hydraulic oil filter, which is the form of a stainless steel wire mesh cut. Circle To assemble with the steel rim that made the filter. Hydraulic oil (5) It acts as a filter of unwanted impurities in the hydraulic oil so that it does not flow into the hydraulic oil.
