Abstract

The utility model belongs to a short-typed waterproof retarder. The piston of the retarder is inserted in the inner cavity of a sliding cylinder body. A piston rod and a sliding cylinder body after the assembly are arranged in the inner cavity of a shell and connected by a stop offset. A height adjustment gasket is positioned between the lower end of the piston and the bearing hole of the shell. An O-typed sealing ring is sleeved in a sealing groove of the stop offset. The ring-shaped card of the stop offset is inserted in a stop groove of the piston rod. The shell is tightly fixed on a matrix by a spring washer and a bolt. An oil-scraping wiper is arranged in a dustproof groove of the shell. As a discharge port is removed from the lower part of the shell to the upper part of the shell and the joint between the piston and the top shell is sealed, the good waterproof function is gotten, thereby achieving the purpose of the retarder.

Description

Short type waterproof is slowed down and is pushed up

Technical field

Short type waterproof is slowed down to push up and is mounted on the yard station track, and a kind of marshalling facilities to skating vehicle carries out safe speed governing operation belongs to railway train arrangement operation speed governing and safety apparatus technical field.

Background technology

The deflation hole on the short type deceleration top of current application is in the bottom of top shell, and the also sealing of the junction of piston rod.Like this, when the railway roadbed impeded drainage, water inlet easily in the shell of top, the normal use on influence deceleration top.As will guaranteeing that the top shell do not intake, must be moving on the deflation hole, and the connecting portion of piston rod and top shell is sealed.

Summary of the invention

The utility model has improved the structure that short type slows down and pushes up, and deflation hole is moved to top from the bottom, has improved the connection mode of piston rod and top shell simultaneously, makes the junction sealing of piston rod and top shell, plays waterproof action.

Short type waterproof slow down the top by housing, sliding oil cylinder, piston rod, end abatement, locating dowel pin, O RunddichtringO, heighten pad, spring washer, bolt and frizing dust ring and form.

Piston rod is inserted in the inner chamber of sliding oil cylinder, and piston rod after the assembling and sliding oil cylinder are contained in the inner chamber the inside of housing, connects with ending writing off; Be equipped with between the bearing hole of the lower end of piston rod and housing and heighten pad, the O RunddichtringO is sleeved on and ends in the seal groove that writes off, and ends writing off being inserted into the ending in the punching of housing; Locating dowel pin is inserted in the knock hole of the knock hole that end to write off and housing, ends the annular snap that writes off and is inserted in ending in the jet-bedding of piston rod; Housing is used spring washer and bolted basically, and the frizing dust ring is contained in the dustproof groove of housing.

The housing on short type waterproof deceleration top is provided with the breach of stepping down, internal thread hole, deflation hole, dustproof groove, oilway, upper bracket, lower seat, bearing hole, ends punching, knock hole; The dustproof stifled upper end that is welded on deflation hole.

The sliding oil cylinder on short type waterproof deceleration top is provided with and promotes with internal thread hole, inner chamber, air-filled pore, seal cover cap knock hole, hole circlip groove.

The piston rod on short type waterproof deceleration top is provided with negative thread valve seat orifice, piston-ring slot, through hole, pressure spring chamber, ends jet-bedding.

What short type slowed down and pushes up only being shaped on only towards cap, knock hole, seal groove, annular snap and sector notch in the abatement.

The specific embodiment

As shown in Figure 1, lack the type waterproof slow down the top by housing 1, sliding oil cylinder 2, piston rod 3, only write off 4, locating dowel pin 5, O RunddichtringO 6, heighten pad 7, spring washer 8, bolt 9 and frizing dust ring 1O and form.

Piston rod 3 is inserted in the inner chamber 2-2 of sliding oil cylinder 2, and piston rod 3 after the assembling and sliding oil cylinder 2 are contained in housing 1 the inside, connects with only writing off 4; Between the bearing hole 1-9 of the lower end of piston rod 3 and housing 1, be equipped with and heighten pad 7, O RunddichtringO 6 is sleeved on and only writes off in 4 the seal groove 4-3, only writing off 4 is inserted in the only punching 1-10 of housing 1, locating dowel pin 5 is inserted in the knock hole 1-11 that only writes off 4 knock hole 4-2 and housing 1, only writes off 4 annular snap 4-4 and is inserted in ending in the jet-bedding 3-5 of piston rod 3; Housing 1 usefulness spring washer 8 and bolt 9 are fastened on basically, and frizing dust ring 10 is contained in the dustproof groove 1-5 of housing 1.

The structure of short type waterproof deceleration top housing 1 such as Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5 are shaped on the breach 1-1 that steps down, internal thread hole 1-2, deflation hole 1-3, dustproof groove 1-5, oilway 1-6, upper bracket 1-7, lower seat 1-8, bearing hole 1-9, end punching 1-10, knock hole 1-11 on the housing 1; Dustproof stifled 1-4 is welded on the upper end of deflation hole 1-3.

The sliding oil cylinder 2 on short type waterproof deceleration top is shaped on the sliding oil cylinder 2 to promote and uses internal thread hole 2-1, inner chamber 2-2, air-filled pore 2-3, seal cover cap knock hole 2-4, hole circlip groove 2-5 as shown in Figure 6.

The piston rod 3 on short type waterproof deceleration top is shaped on negative thread valve seat orifice 3-1, piston-ring slot 3-2, through hole 3-3, pressure spring chamber 3-4, ends jet-bedding 3-5 as shown in Figure 7 on the piston rod 3.

What short type waterproof deceleration was pushed up only writes off 4 as Fig. 8, shown in Figure 9, only writes off to be shaped on 4 only towards cap 4-1, knock hole 4-2, seal groove 4-3, annular snap 4-4 and sector notch 4-5.
