Specific embodiment

As shown in Fig. 2, the present embodiment be one kind can self-draining plug-in movable railing, have guardrail piece and pre-buried base Plinth, guardrail piece can be plugged on embedded foundation by its railing post 1.

Embedded foundation is embedded on the basis of bottom surface in advance in the present embodiment, is arranged in a one-to-one correspondence with the railing post 1 of guardrail piece.In advance Burying basis includes service sleeve 2 and the fixation steel plate 3 positioned at 2 bottom of service sleeve, and the internal diameter of service sleeve 2 is vertical slightly larger than railing The outer diameter of column 1.

Non-return air valve 8 is equipped in the present embodiment inside the railing post 1 of guardrail piece, as shown in figure 3, non-return air valve 8 has Steel plate 801, steel plate 801 is fixed on 1 inner wall of railing post, and 1 internal chamber of railing post is separated lower regions, steel plate 801 Center offer direction stomata, corresponding stomata covers rectangular rubber paster 802, rubber paster 802 in 801 upper surface of steel plate One group of opposite side paste the two sides for being fixed on stomata on steel plate 801, another group of edges free of rubber paster 802, rubber respectively Patch 802 is close to steel plate 801.Rubber paster 802 is heaved upwards under acting below non-return air valve 8 compared with hyperbar, in its freedom End forms venting channels, and rubber paster 802 is adjacent to steel plate 801 under normal condition or low pressure state, blocks stomata.

Inside railing post 1, the rubber piston 6 that can be moved up and down inside railing post 1 is equipped with below non-return air valve 8, Reservoir chamber is formed in railing post 1, between non-return air valve 8 and rubber piston 6, reservoir chamber is corresponded on railing post 1 and is equipped with draining Mouth 9.

Hollow connection tube 7 (see Fig. 4) is coaxially coated on rubber piston 6, the hollow connection tube 7 is by a hollow conduit system It forms, upper end is water outlet, and connecting tube collet 10, pipe of the hollow connection tube 7 close to connecting tube collet 10 is welded and fixed in lower end Water sucking mouth 701 is offered on wall, 7 upper end of hollow connection tube is connected to reservoir chamber by water outlet after rubber piston 6.

Strong magnet 4 is set in 1 bottom of railing post in the present embodiment, is offered on strong magnet 4 logical for hollow connection tube 7 The through-hole crossed (see Fig. 5).Guardrail piece can be inhaled by the fixation steel plate 3 in the strong magnet 4 and embedded foundation of 1 bottom of railing post It closes, realizes that guardrail piece is connect with embedded foundation.

It rubber piston 6 and is connect between strong magnet 4 below through elastic telescopic mechanism, elastic telescopic in the present embodiment Mechanism uses spring 5, and 5 upper end of spring connects 6 lower end surface of rubber piston, and 5 lower end of spring connects strong magnet 4.

As shown in fig. 6, the working principle of the present embodiment is as follows:

When guardrail piece is inserted into embedded foundation, connecting tube collet 10 contacts the fixation steel plate 3 of embedded foundation first, and on column During bar column 1 is with self weight decline, rubber piston 6 is pushed to move up by hollow connection tube 7, while making spring 5 gradually It is elongated, elastic potential energy is gradually increased.Reservoir chamber top non-return air valve 8 is opened at this time, and balance inside and outside differential pressure guarantees rubber piston 6 Normal sliding.

After when top, guardrail piece is fully inserted into bottom hole, the strong magnet 4 of 1 bottom of railing post is tightly adsorbed in embedded foundation Fixation steel plate 3 on, rubber piston 6 is raised to highest point, and spring 5 is also stretched to longest, and elastic potential energy runs up to maximum.

At this point, the rebound pulling force of spring 5 alreadys exceed the static friction force between hollow connection tube 7 and rubber piston 6, bullet Spring 5 starts drag rubber piston 6 and overcomes dynamic friction slide downward between hollow connection tube 7 and rubber piston 6, whole process column Bar column 1 is tightly adsorbed on embedded foundation bottom hole in the case where self weight and strong magnet 4 act on.

When 6 slide downward of rubber piston, non-return air valve 8 is closed, and reservoir chamber is closed and forms negative pressure state with external pressure, Under pressure action, service sleeve 2 internal water accumulation in railing lower part is sucked by reservoir chamber by the water sucking mouth 701 of hollow conduit bottom.

When movable railing is withdrawn, opens discharge outlet 9 and reservoir chamber internal water accumulation, rubber piston 6, spring 5, hollow connection tube is discharged It is spare that 7 equal components return back to initial state.
