Description
Technical field
The utility model relates to hydraulic bjuffer, specifically a kind of hydraulic bjuffer tail plug structure.
Background technique
Hydraulic bjuffer uses field very extensive, such as has in household electrical appliances, pipeline, the vehicles and furniture industry big
Amount is used.The basic structure of hydraulic bjuffer is usually all cylinder body, piston and the piston rod that sealed internal chamber is equipped with comprising one, institute
Piston is stated to be arranged in the inner cavity of cylinder body, the internal chamber wall fluid-tight contact of piston and cylinder body and can along lumen shaft to sliding back and forth,
The inner cavity is divided into two working chambers, the medium runner of two working chambers of connection is provided on piston.Piston rod when work
Band piston is mobile, changes the volume of two working chambers, and hydraulic medium therein passes through one that medium runner becomes smaller from volume
Effluent is to the side to become larger.Since liquid medium has an of a substantially incompressible characteristic of volume, the pace of change of volume by
The latus rectum of medium runner limits, by speed namely cylinder body that suitable medium runner latus rectum, that is, settable volume change is arranged
Relative displacement between piston rod achievees the purpose that impact-reducing, antidetonation.But in existing buffer, buffer
Tail plug is using threaded connection, it is therefore desirable to it is provided with internal screw thread on the main body inner hole of hydraulic cylinder, external screw thread is arranged in tail beyond the Great Wall, when
After piston rod and the installation of piston group, tail plug is spirally connected and is fixed in main body, but the processing of this structure is complicated, craft precision requirement
Height leads to high production cost, and the market competitiveness is weak, therefore has you to be improved further to it.
Utility model content
The purpose of this utility model is to overcome prior art there are the shortcomings that, it is simple to provide a kind of structure, user
Just, production cost is low, a kind of hydraulic bjuffer tail plug structure of simple production process.
The utility model aim is realized with the following methods: a kind of hydraulic bjuffer tail plug structure comprising outer sleeve,
The top of outer sleeve and tail end are provided with opening, and guide sleeve is provided in outer sleeve top, and piston rod is built into outer from guide sleeve
It is connect in sleeve with piston group, it is characterised in that: the tail end of the outer sleeve is provided with tail plug, is formed between piston group and tail plug
Oil pocket；The tail plug includes slow-witted piston, and slow-witted piston is cylindrical is mounted in the inner hole of outer sleeve, is set in the outer circle of slow-witted piston
It is equipped with seal groove, sealing ring is mounted in the seal groove, and sealing ring plays the role of sealing the gap between slow-witted piston and outer sleeve；Institute
It states and is provided with locating slot in the outer circle of slow-witted piston, outer sleeve bulk material is inwardly stamped with link block and is snapped into locating slot, rises
The fixed function to slow-witted piston and outer sleeve is arrived.
The locating slot is the inner groovy on slow-witted outside piston, and inner groovy is formed by cutting slow-witted piston only material.
The link block is to be arranged in outer hub internal bore convex ring, and bulge loop is snapped into locating slot fixed.
The beneficial effects of the utility model are: 1, structure is simple, production cost is low, improves the market competitiveness.2, tail plug is logical
The link block connection being arranged on the locating slot and outer sleeve being provided thereon is crossed, the connection function of tail plug and outer sleeve is played, fills
With simple and fast.
Detailed description of the invention
Fig. 1 is the utility model general assembly effect picture.
Fig. 2 is the utility model structural assembly diagram.
Fig. 3 is the utility model structure sectional view.
Specific embodiment
Specific further instruction is made to the utility model with reference to the accompanying drawing.A kind of hydraulic bjuffer tail plug structure,
Including outer sleeve 1, the top of outer sleeve 1 and tail end are provided with opening, and guide sleeve 2, piston rod 3 are provided in 1 top of outer sleeve
It is built into outer sleeve 1 from guide sleeve 2 and is connect with piston group 4, it is characterised in that: the tail end of the outer sleeve 1 is provided with tail
Plug 5 forms oil pocket 6 between piston group 4 and tail plug 5；The tail plug 5 includes slow-witted piston 51, and slow-witted piston 51 is cylindrical is mounted on
In the inner hole of outer sleeve 1, it is provided with seal groove 52 in the outer circle of slow-witted piston 51, sealing ring 53 is mounted in the seal groove 52, close
Seal 53 is played the role of sealing the gap between slow-witted piston and outer sleeve 1；It is provided with locating slot 54 in the outer circle of the slow-witted piston 51,
1 bulk material of outer sleeve is inwardly stamped with link block 12 and is snapped into locating slot 54, plays to slow-witted piston 51 and outer sleeve 1
Fixed function.
The locating slot 54 is the inner groovy on slow-witted outside piston, and inner groovy is formed by cutting slow-witted piston only material.
The link block 12 is to be arranged in outer hub internal bore convex ring, and bulge loop is snapped into locating slot fixed.
